Coal mine hoisting winch capable of replacing drum conveniently

Abstract

The invention discloses a coal mine hoisting winch capable of replacing a drum conveniently. The hoisting winch comprises a fixed plate and a lead screw; the fixed plate is provided with a first fixedblock; the first fixed block is connected with a first fixed ring; moreover, the first fixed ring and the drum are connected with each other; the drum is provided with a ratchet wheel; the ratchet wheel is connected with a connecting rod through a pawl; the right side of the drum is provided with a fixture block; the fixture block and a second fixed ring are connected with each other; moreover, sliding blocks are arranged under the fixture block; moreover, each sliding block and a corresponding sliding chute are connected with each other; the sliding chutes are formed in a second fixture block; the second fixture block is connected with a turning block through a connection block; the lead screw is arranged on the second fixed ring; the lead screw is connected with a worm gear; and the worm gear is connected with a worm. According to the coal mine hoisting winch capable of replacing the drum conveniently, the first fixed ring and the second fixed ring are correspondingly fixed to the left side and the right side of the drum, so that the rotation of the drum cannot be hindered when the drum is fixed.

Description

technical field [0001] The invention relates to the technical field of hoisting winches for coal mines, in particular to a hoisting winch for coal mines that facilitates the replacement of drums. Background technique [0002] In coal mining, a lifting winch is used, a lifting device that uses a drum to wind a steel wire or a chain to lift or pull heavy objects. However, after a long period of use, the drum of a general lifting winch is excessively worn, and it is inconvenient to replace the drum. When the roller is easy to reverse without control, it is easy to cause unnecessary trouble. [0003] Therefore, we have proposed a coal mine hoisting winch that is easy to replace the drum in order to solve the problem that the drum of the general hoisting winch proposed above is excessively worn after long-term use, and it is inconvenient to replace the drum, and the drum is in use. In the case of control, it is easy to reverse, and it is easy to cause unnecessary troubles. Con...
