Abstract

The invention relates to a winch, in particular to a winch cradle interlocking protection device. According to the winch cradle interlocking protection device, because an electrical appliance interlocking device and a mechanical protection device are arranged, the interlocking protection function of a winch cradle is achieved, and when pulleying happens to the winch, the winch is immediately stopped from running, and personnel security and equipment operation are guaranteed. The winch cradle interlocking protection device comprises the electrical appliance interlocking device and the mechanical protection device, wherein the electrical appliance interlocking device comprises a ground sensing coil installed between mine car rails, the ground sensing coil is connected with a control loop ofthe winch, the mechanical protection device comprises a sleeve fixed to the winch and a stop lever fixedly connected to a steel wire rope, and the steel wire rope penetrates through the sleeve and iswinded around the winch.

Description

Technical field [0001] The invention relates to a winch, in particular to a winch cradle interlocking protection device. Background technique [0002] In the production process of coal mines, the dispatch winch is the most used hoisting equipment in the hoisting and transportation process. Because the dispatching winch has a simple structure and is flexible and convenient to use, it is widely used. However, serious accidents such as wounding and equipment damage often occurred during the use of the winch, which not only affected normal production, but also threatened personal safety. Summary of the invention [0003] The purpose of the present invention is to provide a winch cradle interlocking protection device. By providing electrical interlocking devices and mechanical protection devices, the interlocking protection function of the winch cradle is realized. When the winch is over-rolled, the winch is immediately stopped. , To ensure the safety of personnel and the operation o...
