Abstract
The utility model relates to a single-wheel insulating pulley comprising a pulley assembly, a hook, a rotating shaft, and a rotating shaft connector. A fork handle equipped with a hole is disposed on the bottom of the hook. One end of the rotating shaft connector is fixed at the fork handle of the hook through a bolt. The other end of the rotating shaft connector is also configured in a fork handle shape and is fixed on the rotating shaft through a bolt. The rotating shaft is in movable connection with a rotating shaft fixing seat on the pulley assembly. The single-wheel insulating pulley can be freely rotated within 360 degrees and prevents a deadlocking phenomenon. The groove-shaped hook is not required to cooperate with a rope and can be directly suspended from a tower. The single-wheel insulating pulley resolves a defect of overlong effective stroke in insulator replacement, shortens operating time, increase work efficiency, and reduces operation potential safety hazard.
Description
Technical field
The utility model relates to a kind of lifting tool, relates in particular to a kind of New single wheel insulation coaster.
Background technology
Single-wheel insulation coaster is mainly applicable to 35kV-500kV transmission line, its effect is in the process of replacing insulator, coordinated insulation rope, the insulator of insulating tool, checkout equipment, metal Work tool and required replacing and other small tool of operation etc. of using for lifting operation, traditional insulation coaster turns to underaction, often there will be under cable traction, pulley is sprained causes pulley and the stuck phenomenon of supporting plate; Traditional insulation coaster is used in conjunction with in process at rope sling, can lengthen the effective travel of lifting after rope is stressed, and the validity that this has just reduced coaster, wastes time and energy when use, inefficiency, and dangerous values is higher, has very large potential safety hazard.
Summary of the invention
(1) technical problem that will solve.For addressing the above problem, the utility model proposes a kind of New single wheel insulation coaster, it can 360 ° rotates freely, there will not be stuck phenomenon, and groove shape hook coordinates without rope, can directly hang on tower material, solve and changed the long defect of effective travel in insulator.(2) technical scheme.This New single wheel insulation coaster, it comprises pulley assembly, hook, rotating shaft and rotating shaft connector, described pulley assembly comprises a nylon wheel, a rotating shaft holder and two supporting plates, described hook lower end is provided with a fork handle with holes, described rotating shaft connector one end is bolted on hook fork handle place, the described rotating shaft connector other end is set to equally fork handle shape and rotating shaft utilizes bolt to fix, and described rotating shaft is flexibly connected with the rotating shaft holder on pulley assembly.Further, to be set to grooved hook-shaped for described hook.Further, described supporting plate material is epoxy plate.Further, described nylon wheel is fixed in the middle of two supporting plates by a little axle, free to rotate.(3) beneficial effect.The utility model compared with prior art, it has following beneficial effect: the utility model single-wheel insulation coaster has newly been established a turning gear between hook and pulley assembly, finally realize 360 °, pulley, multiaspect, the function of Space Rotating, in use procedure, there will not be the stuck phenomenon of pulley, it is hook-shaped that hook is designed to grooved, be used in conjunction with without rope sling, can directly be suspended on the function on tower material, solve and changed the long defect of effective travel in insulator, new single-wheel insulation coaster after improvement in use, to changing 500kV tension resistant four insulator string and changing 220kV linear string insulator, the suspension coaster time greatly reduced than in the past, because of the defect problem of stuck in operation or stroke etc., activity duration and labour intensity are also greatly reduced and are reduced again, and corresponding coaster frictional force also just diminishes much naturally, has improved operating efficiency, has reduced potential safety hazard.
