Abstract
The utility model relates to a friction lifting automatic balance linkage of restricting more that improves on wedge block formula hydraulic pressure transfers rope linkage basis. The original wedge block and hydraulic cylinder are replaced by a hydraulic cylinder with a capsule inside, the capsules in the hydraulic cylinders on the suspension devices are communicated by hoses, and the capsules are filled with liquid. The tension between the steel cables on each suspension device is kept equal through the pressure transmission of the liquid. The automatic balance can be formed when the device is in motion or is still.
Description
The utility model relates to many steel wire rope tension balances of a kind of friction drive hoist automatic regulating apparatus, a kind of multirope friction winder self-equalizing suspension gear of more specifically saying so.
Now in all multi-rope friction hoisting equipment in countries in the world, equalization of strain equipment mainly contains three kinds of forms between many steel ropes: the first, lever: utilize lever principle to regulate the balance of steel rope, its shortcoming is: balancing device is owing to be subjected to size and materials limitations, can only be used for the less occasion of lift stroke, and balance quality is very low.The second, spring loaded: the same with lever, stroke can not be big, is generally＜300m, is used for elevator more, basic not use on the mine.The 3rd, fluid pressure type: utilize hydraulic actuating cylinder to adjust equalization of strain between steel rope, its balance quality is all higher than lever and spring loaded, stroke is also big, but for a long time, can't solve the influence of the seal leakage problem of hydraulic actuating cylinder and working environment to hydraulic cylinder type balancing device reliability always, only be used as the adjustment of tension force when static, and can not realize kinetic balance, reason is because quiet timing fills up the pad size error that adds, the difference of degree of wear, stiffness variation difference between the steel rope, the steel rope of adjusting when static is got into smooth and new overbalance can be formed, and constantly aggravation, be difficult to find.In addition, tension imbalance has quickened the wearing and tearing and the steel rope fatigue damage of liner, can cause rope-broken accident when serious.
The purpose of this utility model is in order to provide a kind of no matter when static, still can both to guarantee multirope friction winder self-balanced suspension gear when motion.
The purpose of this utility model can realize in the following manner: a kind of multirope friction winder self-equalizing suspension gear, be to transfer on the rope suspension gear basis improved at existing Wedge-type hydraulic pressure, replace original voussoir and hydraulic actuating cylinder with a special hydraulic actuating cylinder, described special hydraulic actuating cylinder includes cylinder body, piston rod and airtight capsule are arranged in it, make the connection of the capsule in the hydraulic actuating cylinder on several suspension gears with flexible pipe, according to the fluid pressure transfer principle, steel rope stress balance on the suspension gear that can guarantee to link to each other, no matter when static, still when motion, can both keep balance.
