| titleOfInvention | A kind of protective plate for coal mining roadway |
| abstract | The invention discloses a protective plate for coal mining roadway, comprising a bottom plate and a stress plate, four supporting legs are fixedly connected to the top of the bottom plate, and a load-bearing plate is fixedly connected to the top of the four supporting legs. The load-bearing plate is located above the load-bearing plate, and a buffer mechanism is arranged between the load-bearing plate and the load-bearing plate. The outer wall is hinged with four first movable rods, the top of the load-bearing plate is provided with four long grooves, the end of the first movable rod away from the mounting plate is connected with the long grooves in a limited position and sliding, and is located at the inner wall of the long groove. A spring is fixedly connected between the first movable rod and the inner wall of the long slot. Through the cooperation of the above-mentioned structures, the present invention can effectively resist the collapse or falling pressure from the top of the roadway, and can provide an effective safe area for construction workers in a crisis. |
