Abstract

The invention relates to the technical field of hoisting tackles, and discloses a uniform speed pulley mechanism capable of avoiding an unstable operation of an electric tackle. The mechanism comprises a rotating shaft, wherein a mounting hole is formed in the front surface of the rotating shaft, a supporting rod is movably connected in the mounting hole, and a connecting rod is hinged to the end,far away from the mounting hole, of the supporting rod; A slide block is movably connected to the end, far away from the supporting rod, of the connecting rod, and a variable resistance mechanism ismovably connected to the back surface of the slide block. According to the uniform speed pulley mechanism capable of avoiding the unstable operation of the electric tackle, through the cooperative useof the variable resistance mechanism and the rotating shaft, when the rotating speed of the rotating shaft is high and exceeds the rated rotating speed, the resistance is automatically increased, andthe rotating speed of the rotating shaft is reduced; when the rotating speed of the rotating shaft is low and is lower than the rated rotating speed, the resistance is automatically reduced, the rotating speed of the rotating shaft is increased, the effect of always keeping the rotating shaft at a uniform speed is achieved, and the problem of unstable vertical hoisting speed caused by a unstablegravity center of a hoisted object or worker operation is avoided.

Description

Technical field[0001]The invention relates to the technical field of hoisting pulleys, in particular to a uniform speed pulley mechanism for avoiding unstable operation of electric pulleys.Background technique[0002]Hoisting tackle is an important hoisting tool with simple structure and easy to use. It can change the direction of the traction cable of the tackle and the tackle group and lift or move the moving objects many times, especially the tackle group composed of the tackle combined with the hoist, Masts or other lifting appliances are widely used in construction and installation operations. Most of the current workshops and construction sites use electric pulleys, which are easy to operate and can lift heavy objects vertically. However, the current electric pulleys on the market may cause the vertical lifting speed to be unstable due to the unstable center of gravity of the lifting objects or the operation problems of the workers. Stable, this will result in unstable force of ...
