Abstract
A kind of automatic wire tension balancing device for multiple wire hoist is to utilize the card fag end to link up with a balance lifting rope between per two steel cables, the balance lifting rope is on a balance wheel, rely on balance lifting rope peace weighing apparatus wheel to rotate and makes two steel cable tension force obtain balance, the balance between the every pair of steel cable is to be undertaken by gusset piece on the balancing axle and trammel beam.This balancing device, can make multi rope winding steel cable its tension force of self-equalizing constantly in operational process, reach the stressed unanimity of respectively restricting, the scope that its adjusting range can be reconciled much larger than hydraulic ram, and needn't be on the roll friction liner recessing, thereby prolonged service life of steel cable and roll friction liner, reduce maintenance capacity, and can increase the safe reliability of gig.
Description
The present invention is the balancing device that is used for balanced steel cable or wirerope tension force in a kind of multi-rope hoist, exactly is a kind of automatic wire tension balancing device for multiple wire hoist.
But the multi rope winding technology is more and more generally used in gig at present owing to have advantages such as safe material saving, simplified apparatus, when adopting the multi rope winding technology, how to guarantee that every lifting steel cable stressed (tension force) equilibrium is the key of technology.But because the preparation technology of steel cable and the influence of material, objectively always there is difference in each steel cable coefficient of elasticity, and particularly the influence of this difference is just outstanding especially for the dark mine hoisting of hundreds of rice, solves also very difficult.For solving many suffered equalization of strains of hoisting rope, be to be added with a hydraulic ram at present at every end, by modulated pressure oil cylinder pull bar size, adjust and promote steel cable length, but this method variable range less (adjustable 400~450mm).The way of recessing on cylinder can be taked in addition, the tension force weighing apparatus of hoisting rope can be solved to a certain extent.But this cylinder recessing just temporarily solves the Tension Difference between many ropes, and because frequent car grooving is scrapped the roll friction liner too early.In addition, used steel cable in multi-rope hoist, as long as there is one to scrap, all the other steel cables all need to change again, so multi-rope hoist friction lining and steel cable used life are short, maintenance capacity is big.How to solve multi-rope hoist steel cable equalization of strain problem, be still key problem in technology to be solved.
The purpose of this invention is to provide a kind of steel cable tension balance device that is used for multi-rope hoist, it can make operating lifting steel cable self-equalizing, reach and promote the stressed equalization of steel cable, simplify lifting means, prolonged life-span of steel cable, roll friction liner, reduce maintenance, simultaneously the safety of multi-rope hoist is improved.The lifting steel cable of multi-rope hoist is generally 2,4, generally be to link by hydraulic ram and lifting container, automatic balance device of the present invention, utilize the card fag end to link up with a balance lifting rope between per two steel cables, the balance lifting rope is on a balance wheel, one gusset piece is installed on the balance wheel, can be directly connected below the gusset piece or two gusset pieces link with the trammel beam two ends respectively again, and the trammel beam center connects with lifting container by coupling head with lifting container.The equilibrium process of multi-rope hoist steel cable automatic balance device of the present invention is as follows: when the steel cable of multi-rope hoist is stressed when changing (tension force), at first per two steel cables rotate by balance lifting rope peace weighing apparatus wheel and obtain balance, claim the one-level balance; Obtain to carry out balance by gusset piece and trammel beam between two steel cables of balance and the two other steel cable, claim the secondary balance.For making balance play flexible, antifriction-bearing box all is housed in balance wheel, trammel beam, many rope tensions are changed obtain rapidly adjusting.
An example of the present invention can be illustrated by Fig. 1.Fig. 1 is for using the lifting steel cable automatic balance device of 4 wider rope gigs.Among the figure 1, promote steel cable, 1#, 2#, 3# and 4# and be respectively the steel cable sequence number; 2, card fag end; 3, balance lifting rope; 4, balance wheel, wherein I, II are represented two balance wheels; 5, gusset piece; 6, trammel beam; 7, coupling head; 8, lifting container.By 2 one balance lifting ropes of card fag end 1#, 3# steel cable are linked up, and walk around the balance wheel I, another balance lifting rope links up 2#, 4# steel cable, walk around the balance wheel II, gusset piece 5 is installed in the two ends of trammel beam 6 respectively on balance wheel I, the II, lifting container 8 is lifted on by coupling head 7 on the center shaft of trammel beam 6, for reducing friction, antifriction-bearing box all being housed in the center shaft of the wheel shaft of balance wheel I, II and trammel beam 6.Promote the Tension Difference between steel cable 1# and the 3#, can realize its balance (being the one-level balance) by balance lifting rope peace weighing apparatus wheel I, same balance wheel II realizes the equalization of strain of 2# and 4# steel cable; Equilibrium process between balance wheel I and the II is realized (being the secondary balance) by trammel beam 6, thereby realizes the steel cable self-equalizing of 4 rope gigs.For reducing the balance wheel diameter, the balance lifting rope can be made by many thin steel ropes in parallel in addition.
Gusset piece on the balance wheel 45 directly can be connected with lifting container for better simply duplex type gig, and can increase by a balance wheel according to a pair of hoisting rope of every increase for the above multi-rope hoist of 4 ropes, change the corresponding trammel beam 6 of design again, to realize the self-equalizing of steel cable tension force.Promptly adopt balancing device of the present invention, can make multi rope winding steel cable its tension force of self-equalizing constantly in operational process, reach the stressed unanimity of respectively restricting, its adjusting range is big more than hydraulic ram, and needn't be on the roll friction liner recessing.Thereby prolonged service life of steel cable and roll friction liner, reduce maintenance capacity, and can increase the safety and reliability of gig.
