Protection device for breakage of elevator steel wire rope

Abstract

The invention relates to the technical field of machines, and discloses a protection device for breakage of an elevator steel wire rope. The protection device comprises a base, a lifting device, an anti-falling plate, a cargo basket and a rope fixing ring. The base is a rectangular flat plate, an upper anti-falling box is fixedly mounted above the base, the upper anti-falling box is a rectangularhollow box body, a lower anti-falling box is fixedly mounted above the base, the lower anti-falling box is a rectangular hollow box body, the anti-falling plate is arranged above the base, and the left end and the right end of the anti-falling plate penetrate through sliding ways on the left side and the right side separately. The protection device is novel in concept, compact in structure, reliable in work, convenient to use and low in manufacturing cost, when the elevator steel wire rope is suddenly broken, cargoes are received by the anti-falling plate, the anti-falling plate inclines rightwards, based on the lever principle, teeth fixed on anti-falling blocks are engaged with teeth on the inner walls of the anti-falling boxes, the anti-falling plate is locked, the cargoes are supportedby the cargo basket on the anti-falling plate, the heavy objects are automatically prevented from falling from high altitudes, the production safety can be strictly guaranteed, and major safety accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a protection device for breakage of a steel wire rope of a hoist. Background technique [0002] Because of its simple structure, the hoist is widely used by industrial and mining enterprises as a tool for moving and lifting heavy objects. However, if the wire rope of the hoist breaks, the lifted heavy objects will fall from a high altitude, causing serious safety accidents, especially for explosives manufacturers. If the wire rope of the hoist breaks, a chain explosion accident will occur, and the consequences will be disastrous. . Therefore, a protective device is needed on the hoist. When the wire rope of the hoist breaks, the protective device can catch the falling goods, so that the goods will not fall quickly to the ground, which can prevent the occurrence of major safety accidents when heavy objects fall from high altitude. Contents of the invention [0003] (1) Solve...
