Product Introduction

Introduction of pneumatic mechanical locking device

The damper hydraulic locking device is designed based on the principle of mechanical rotation. It is mainly used for mutual locking between the damper in underground coal mine. It has the characteristics of simple structure, flexible opening, convenient installation, no need to use all kinds of energy, wide applicability, reliable blocking and so on.

Operating principle of pneumatic mechanical latching device

The small damper lock chute works with the small damper lock lever fixed on the locking string to form the small damper lock organization of damper I. The difference is that the opening of the damper and its relief damper changes from "pull" to "push". Coal mine air door locking device is using two sets of as a set of cooperation, to which a set of mine air door locking device to clarify the operation process, the hydraulic cylinder of the hydraulic cylinder equipment equipment on the partition wall, piston rod connecting device on the throttle, accumulator, tubing and tubing on the roadway side wall, door lock device in air door, lock device on the door frame.

When damper I opened, the top set of atresia offshoring piece by wire rope drive the organization's activities, the sliding block popup, block by the spring pin spacing, move the head to the pin shaft bearing, push pin shaft to the second hole inside out, make the pin stuck activity block header, n by wire rope tension, in the closure of air condition, air door is mine ventilation equipment, located between the inlet and return air shaft or contact which between the inlet and return air lane. Air filtration assembly the lower end of the two bodies is provided with a drain pipe.

So, throttle air door locking device, the air door locking device contains the atresia, the second lock, the control valve and the second control valve, as described in the top of the block contains the top closure main body and the top slot, is described in the second atresia contains the second locking the subject and the second slot, described the top closure on the main body is equipped with the top of the cylinder and the piston rod with referred to the top of the cylinder cohesion and cooperation with referred to the top slot at the top of the locks, described the second closure on the subject has mentioned in the second cylinder and the cylinder piston rod cohesion and cooperation with described in the second phase lock slot second locks; The second control valve is connected with the top cylinder, and the top control valve is connected with the second cylinder.

Damper mechanical latching device structure

Damper mechanical locking device including: installed on the roadway of pulleys and ropes, described at both ends of the ropes are respectively fixed on the two door bolt, described the two door bolt is installed on the two air door, door bolt installation location is described: hinge connecting to shutter doors open one side of the top the shutter doors, door bolt can be described described around the hinge to the doors open in the direction of the turn.
