AI Technical Summary

Technical Problem

Existing mine ventilation louvers are laborious to adjust ventilation volume and difficult to fix. Installation and disassembly are cumbersome, especially in complex, narrow or high-altitude environments, which increases the labor intensity of workers and reduces maintenance efficiency.

Method used

The positioning structure adopts a combination of a limit rod and a limit tube, and achieves quick locking through a docking mechanism. The window leaf angle is adjusted by using a telescopic cylinder to drive a rack and pinion. Combined with the automatic locking design of pawl and ratchet, the installation and disassembly process is simplified.

Benefits of technology

It enables a convenient installation and disassembly process, reduces the labor intensity of workers, and improves the maintenance efficiency and installation convenience of the ventilation system.

Abstract

The utility model relates to the technical field of shutters, and discloses a mining exhaust shutter convenient to mount and dismount, which comprises a support frame and a window frame fixedly connected to the left end of the support frame, and a plurality of shutter blades are uniformly mounted in the window frame from top to bottom; limiting rods are fixedly connected to the upper ends and the lower ends of the surfaces of the front side and the rear side of the supporting frame, the limiting rods are movably sleeved with limiting pipes, and butt joint mechanisms are arranged in the middles of the surfaces of the front side and the rear side of the supporting frame; when the device is installed for the first time, although a limiting pipe and a C-shaped plate need to be fixed on a roadway wall or a ventilation opening in advance, only a limiting rod of a supporting frame needs to be inserted into the limiting pipe and then pushed rightwards during subsequent installation, a second rack is meshed with a second gear, a pawl automatically clamps a ratchet wheel under the action of a spring, firm locking is completed, and the process is extremely convenient and fast; during disassembly, the whole supporting frame can be easily pulled out leftwards only by simultaneously pulling the pawls on the two sides upwards with two hands to be separated from the ratchet wheels, and maintenance is extremely convenient.
