Mine winch balance chain and lock catch type lifting hook device

Abstract

Provided is a mine winch balance chain and lock catch type lifting hook device. The mine winch balance chain and lock catch type lifting hook device is used for preventing the phenomenon that casualty accidents happen when a lifting hook is separated from happening when ore of an inclined shaft of a mine is lifted. According to the balance chain principle, when a winch is used for carrying out lifting, a steel wire rope violently swings, impact force borne by the lifting hook of the winch is maximum, just like the principle in the physics, the distance between a balance wheel and an origin is the largest, the impact force can be reduced through the balance effect of an annular chain, and the technical problem that the lifting hook is separated due to the impact force can be solved. The balance chain is connected with the steel wire rope, the other end of the balance chain is connected with the lifting hook head of the lock catch type lifting hook, and the lowermost end of the balance chain is connected with a hanging ring of a tramcar. The lock catch type lifting hook comprises the lifting hook head, a spring, an elastic opening, a locking bar and a rivet shaft. The hanging ring is fixed to the tramcar, the tip of the elastic opening is longer than the locking bar, the locking bar is usually supported on the elastic opening through the spring and is closed, the head end of the spring is fixedly arranged in a rivet shaft hole, when the lock catch type lifting hook is hung or disassembled, a user presses the locking bar with a hand, the spring is compressed, and the elastic opening is opened.

Description

technical field [0001] The invention relates to a mine winch balance chain and a locking hook device. Specifically, the inclined shaft of the mine adopts a device for lifting ore and coal by a winch, which is convenient and quick, especially safe, and prevents and avoids decoupling personal casualties in the lifting. Background technique [0002] At present, the hook device of the known mining winch hoisting material and ore is all that the hook is directly hung on the shackle of the Sheng coal, ore, material box or the shackle of the mine car. When the steel wire rope swings a lot, it is the same as the principle of the balance wheel in physics. Especially at the track joint of the mine winch, if the installation is uneven and the coal mine car swings back and forth, the hook will sometimes be unhooked. A personal injury accident occurred in which the mine cart fell. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies ...
