Downhole ventilation device capable of being controlled lightly

Abstract

The invention relates to an underground light control ventilation device which comprises an air door, a fixing piece is installed on a roadway on the side portion of the air door, a lower pulley is installed on the fixing piece, an upper pulley and a steel wire rope buckle are installed on the upper portion of the air door, and the upper pulley and the steel wire rope buckle are located in the same horizontal direction. The steel wire rope buckle is located on one side of the upper pulley, the lower pulley is arranged on the other side of the upper pulley, and the lower pulley is located below the upper pulley. One end of a steel wire rope is connected to the steel wire rope buckle, the other end of the steel wire rope sequentially winds around the upper pulley and the lower pulley and then is provided with a balance weight barrel, and the balance weight barrel is arranged in the vertical direction. The ventilation system has the advantages that the transportation efficiency is improved, and the stability of the ventilation system is ensured. The opening time is shortened due to the light opening of the air door, and the transportation efficiency is improved; meanwhile, the air door is normally opened and closed, stable operation of the ventilation system is guaranteed, and a good working environment is created.

Description

technical field [0001] The invention relates to a ventilating device for downhole use and portability control. Background technique [0002] Due to the large pressure difference between the inside and outside of the mine auxiliary fan, the damper is particularly difficult to open. Generally, it takes 1-2 strong people to open it, and it is easy to cause accidents of squeezing hands and hurting people if you are not careful; The damper switch is not in place, or it is easy to collide with the mine car and be damaged due to the reason that it is not fixed firmly and is suddenly closed under the action of wind pressure. came severely affected. Contents of the invention [0003] In order to overcome the defects of the prior art, solve the difficulty of opening the air door at the auxiliary fan fan, the inconvenience of electric locomotive transportation, prevent the occurrence of injuries, and reduce the damage of the air door, the present invention provides a ventilating dev...
