Abstract

The invention discloses an anti-pinch mechanism of a mine pneumatic damper, relates to the technical field of the anti-pinch mechanism, and aims to solve the problem that the existing mine pneumatic damper anti-pinch mechanism is complicated and causes the anti-pinch mechanism to be inconvenient to use. The inside of the door frame of the pneumatic damper is provided with a first main body of the left damper, and one side of the first main body of the left damper is provided with a first main body of the right damper, and the inner walls of the first main body of the right damper and the first main body of the left damper are both provided with There is a first slide groove, one side of the first slide groove is provided with a fixed slide plate, the outer wall of the fixed slide plate is provided with a manual power-assisted handle, and the manual power-assisted handle is fixedly connected with the fixed slide plate, and one end of the fixed slide plate is provided with There are two fixed blocks, one side of the fixed block is provided with a circular ring, and the circular ring is fixedly connected with the fixed block, and the other end of the fixed slide plate is provided with a damper.

Description

technical field [0001] The invention relates to the technical field of anti-pinch mechanisms, in particular to an anti-pinch mechanism for mine pneumatic dampers. Background technique [0002] Pneumatic regulating damper is composed of executive mechanism and regulating mechanism. The executive mechanism is the thrust part of the regulating valve. It generates corresponding thrust according to the pressure of the control signal to push the regulating mechanism to act. The damper is an important equipment for ventilation safety in the mining industry. At present, the commonly used mine damper is a fully pneumatic automatic locking damper. This damper is installed between the door frame and the damper with a cylinder, and the damper is pushed or pulled back under the action of the cylinder piston rod, so as to automatically control the opening or closing of the damper. This kind of automatic control damper realizes automatic control to the greatest extent, but it also creates...
