PLC controlled mine hoist brake device

Mine hoist 1 ton chain hoist is an important protective device mine hoist. The braking device can be summarized as follows:

(1) at the end or lifting hoist not work reliably live gate hoist.
(2) speed hoist participate in the deceleration phase control.
(3) As a safety mechanism in the event of an emergency, to enhance the system protection.
(4) double drum hoist rope clutch when opening tune, replacement level, adjust the rope length, can live live drum brake, release the die roll to be adjusted rope operation.
     Currently 1 phase hoist brake disc brake mostly braking system consists of brake and hydraulic components. In the hoist operation use, although the design of the brake system tuning braking torque over multiple hoist static torque of three times, but still due to brake system failure caused over volume, squat cans and other accidents, causing serious economic loss.
     According to the analysis of the reliability of the braking system, brake system, brake disc causes of accidents caused by:
(1) hydraulic standing emergency braking, poor oil return pipe.
(2) hydraulic brake pressure regulator stability is not enough work.
(3) residual pressure is too high, the solenoid valve failure.
(4) brake failure, such as fatigue or rupture disc springs, brake shoe pollution caused by insufficient braking torque and so on. The electronically controlled part of the entire hydraulic station programmable controller (PLC), which will greatly improve the reliability of electronic control systems; and increase interaction with the field devices match the flexibility to achieve a variety of functional changes.

Small electric winch traction is used to set the value of the pound

Small electric winch traction is used to set the value of the pound, can be converted to convert tonnes or kilograms. The best choice for high winch pounds, because the weight of a vehicle is often trapped in much higher daily weight. Do not exceed the traction winch wire rope hoist manufacturers traction object.wound on the reel turns small electric winch rope more smaller outer tension. The reel-long winch can reduce the number of laps wound, to increase the outer traction.Rely on the vehicle's own power system driven winch, advantages: You can use basic normal in the case of a vehicle fire high quality electric chain hoist vdeath is unmatched by other winch, especially for water and more areas have great advantages, easy to install and can be installed quickly realize multi-position shift. Disadvantages: You can not sustain long-term use (vehicle itself power system limitations, its easy to heat and other reasons), the smaller the driving force of most electric winch can provide, applying force only in one direction (installed in front of the small electric hoist car only to before pulling, installed in the rear can only pull back).Of course, using the winch was starting the installation. Although not complicated, but it is the most important step, because it is directly related to the subsequent steps and winch use of effects. Most important to note that the noose drum situation before the start and throughout the process should ensure uniform wound noose.

wire rope

The steel monorail wire rope hoist is one of the components of a very high rate of hoist is used, this isdue to the unique characteristics of its decision. Compared with the rigid component of wire rope, wire rope has the advantages of high strength, light weight, good flexibility,impact resistance and other characteristics, especially prominent is the safety reliability of it.‍

Steel wire rope electric hoist used in normal circumstances will not generally besuddenly broken, even if the failure is also a precursor, generally from the individual,local broken wire, to the progressive development of the rope, is a time process, if thewire rope suddenly broken, because the load exceeds the limit breaking force the rope suddenly failure occurred. This provides such a possibility, as long as usual to strengthen safety management and use of wire rope for electric hoist, caused by wind tubine hoist accidents can be avoided. But the electric wire rope hoist force status changing,complex work environment, the failure in addition to mechanical damage, improper selection, improper structure maintenance checks, wire rope failure reason notpromptly scrapped and update and so on.‍

Application of the technology in electric hoist hook

electric hoist trolley hook is a hook hoisting machinery in the most common. By electric hoistand pulley block part is hung on the hoisting mechanism of the wire rope or chain.According to the shape is divided into single and double hook hook, according to the manufacturing method for forging and laminated. three phase electric hoist hook is made of gold, steel, heat treated, chain, annealing, surface anti-corrosiontreatment produced, we understand in detail the application of the technology in electric hoist hook.

Electric hoist single hook has the advantages of simple manufacture, convenient use,but the stress condition is not good, mostly in the weight for the workplace 80 tons; big lifting weight often use force symmetrical double hook. Laminated hook which is composed of a plurality of cutting steel plate riveted together, the hook will not damage the cracks of individual plates, security is better, but the large self weight,mostly used in large capacity or the lifting of the molten steel ladle crane. The hook is often affected by the impact during the operation, the good toughness of high quality carbon steel manufacturing.

Mainly because of cheap wire rope hoist  in the use process, there are rarely have an overload situation. In this case, there will be deformation of the hook. And hook groupgeneral in the hanging point, is not easy to detect, if there are serious consequences.The hook is very easy to see the visual hook changes, minimize risk hook deformationalso continue to work. So the artificial let tensile strength hook group is different, it is necessary to.‍

Electric Stacker often use should pay attention to maintenance , especially for electric cars piled high maintenance system to do better , then how do electric stacker hydraulic system maintenance job?
 select the appropriate hydraulic oil:
Hydraulic oil in the hydraulic system of electric forklift trucks passing plays pressure , lubrication , cooling and sealing effect, the inappropriate choice of hydraulic oil hydraulic system failure and durability of the early decline. When grade hydraulic oil should 15 ton electric chain hoist randomly select "Manual" specified in special circumstances need to use on behalf of the oil, it should seek the same performance as the original grade performance. Different brands of hydraulic oil can not be mixed , to prevent hydraulic oil to produce a chemical reaction  the performance changes. Dark brown , white , smelly oil hydraulic oil is bad you can not use .2, to prevent air from entering the hydraulic system mini electric hoist Containing hydraulic fluid under pressure in the temperature volume ratio of 6 to 8% of the air pressure is reduced when the air is free from the oil , the hydraulic components bubble burst " cavitation " noise. A lot of air into the oil will cause " cavitation " phenomenon intensified, hydraulic oil compressibility increases, job insecurity, reduced efficiency , implementation of components appear to work "crawling " and other adverse consequences. In addition , the air also makes hydraulic oil oxidation, accelerated deterioration of the oil.

wire rope winch This is because the laser is directional

Ranging laser light is one of the earliest applications. This is because the laser is directional , high  brightness , good color and many other advantages . 1965 years ago the Soviet Union using laser measuring  the distance between the Earth and the Moon (380 × 103km) error of only 250m. After the Americans landing  on the moon in 1969 set the mirror on the lunar surface , but also with a laser to measure the Earth-Moon  distance , the error is only 15cm. [ 14 ] Although the high -precision laser distance sensor has been  listed for many years , but because of its price is too high , has not been widely used . Recently, due to  the significant permanent magnetic lifter decline in their prices , making it a cost-effective areas ranging approach. After  comprehensive consideration , we decided to take the lead in the industry of weight using laser distance  sensor for non-contact position measurement, this not only ensures the safety test accuracy and test  process can be slipped easily measure the amount of brake weights , lifting parameters such as speed and  position to solve the wire 20 , Southeast University, master's degree thesis ( 1 ) spatial segregation :  Let susceptible to interference away from the interference source crane trolley signal lines or circuits , this is the  most effective measures to suppress interference sources. Avoid parallel lines and the strong and weak  signal line signal lines away from strong electrical feeder lines must go alone . Must not be mixed with  the signal line to pull together ; must take the analog signal and digital signal lines separate line ;  avoid strong signal line parallel with the weak signal line , if the conditions as much as possible so that  the two orthogonal . ( 2 ) Screening: overcoming the electric-field coupling is the most effective method  of interference shielding . Because placed in the hollow conductor or metal objects are not affected by  external electric field . However, when an electric field coupling interference shield , the shield  conductor layer is preferably not connected at both ends

Electric wire rope hoist

After the wire rope hoist used for some time , the gear will be worn, what is the reason for this liftech motorized chain hoist phenomenon is formed below us ; ? Do a detailed analysis .
Transmission gear wire rope hoist on another failure mode is wear, worn tooth thinning. If there is wear due to impurities in the oil , generally referred to abrasive wear. This wear often occurs in the deep channel scraping tooth top and root scraping section perpendicular to the line track and parallel to each other . After scraping the road appears to rise in the gear unit oil , gear shrill noise occurs , then you must replace the oil . Because tooth deviation installation center distance deviation is too large , may cause tooth gear pair top edge portion of the transition curve and the tooth root excessive compression , so that part of the tooth root fillet produce severe wear. Due to overload , tends to make the drive wheel tooth or teeth of the driven pulley of the top ( also sometimes occur along the entire tooth surface) of a thin layer is worn away . Lifting gear reducer mechanism for the wear, tooth thickness of not less than 60% of the original tooth liftech portable electric hoist thickness for wear after running gear tooth thickness institutions should not be less than 80% of the original tooth thickness exceeds the standard should be replaced with new gear . Tooth wear can be measured with a thick tooth pitch circle caliper measurements to test the tooth thickness . Measuring method shown in FIG . Caliper Caliper is a comprehensive measure tooth vernier caliper and depth gauge , used to measure tooth thickness . When measuring , starting with drawings isolated tooth height ( ie, from division to round the top of the tooth height ) , the vertical scale measuring tooth caliper raised the height. Then, the card foot stuck teeth , tooth thickness measurement with a level of scale . Measurement accuracy up to 0.02mm.

Single rope winding lifting equipment

An earlier onset , it is reliable, simple structure, but only for shallow and medium depth of the mine , and the terminal load is not too large . For deep wells and the terminal load is large, a large rope and hoist upgrade roll diameter , resulting in a hoist equipmentlarge volume , gravity soared, making the hoisting rope and hoist the manufacture , transport and use on both inconvenience. Thus , to a liftech cheap wire rope hoistcertain extent, limit the single rope winding hoist used in deep well conditions. Friction appears to enhance its development machine , to a certain extent, solve the single rope winding hoist that appear under the condition of deep problems. However , things are always divided into two . Generally used to enhance the friction tail rope balanced tension at both ends to reduce the error and improve reliability. Thus , the container connection with hoisting rope rope section , the static stress changes with position changes of the container . When the container is located in the unloading liftech hoist and trolleyposition the wellhead , the gravity of the entire container and the end of the gravity are acting on the rope of the section ; arrival when the container bottom before loading position to withstand only the gravity of the section of the container. In other words, the entire upgrade process, with the hoisting rope section of the vessel to bear in connection with an amplitude of . static stress changes σj = qH / S0 of (q is the tail rope per meter gravity , N / m H as lifting height , m S0 to enhance the cross sectional area of ​​the wire rope , cm2).
