A coal mine underground fire truck

Abstract

The invention relates to a coal mine underground fire truck, which comprises a storage box, a first chassis and a second chassis, track wheels are arranged on the bottom of the first chassis, universal wheels are arranged on the bottom of the second chassis, the first chassis, the second The chassis are connected by a hinged structure extending along the front-to-back direction of the hinge axis. The first chassis is provided with a first track extending in the left-right direction, and the second chassis is provided with a second track extending in the left-right direction and arranged correspondingly to the first track. The bottom of the placement box is provided with a track matching structure, the placement box has a first working position that moves to the first track, and a second chassis is provided between the placement box and the second chassis for placing the box at the first working position. Limit to the second chassis limit structure standing on the right side of the placement box. The invention provides a coal mine underground fire engine which can not only use the mine underground track to walk, but also can walk on the mine underground road.

Description

technical field [0001] The invention relates to a coal mine underground fire truck in the field of coal mine fire safety. Background technique [0002] Mine fires are also called mine fires or underground fires, which refer to fires that occur in coal mine underground roadways, working faces, goafs and other places. A ground fire that can spread and threaten underground safety is also called a mine fire. Fires in mines often lead to casualties, equipment loss, mine shutdown, resource destruction, and even explosions of gas, coal dust or sulfide mine dust. [0003] After a fire breaks out in the mine, the main job that workers can do is to extinguish the fire in time. At present, the fire extinguishing equipment used in the mine is placed at a fixed point, and the fire extinguishing equipment is placed separately or collectively. However, if the fire occurs in a place far away from the fire extinguishing equipment, Or if the fire extinguishing equipment is not enough, the f...

AI Technical Summary

Problems solved by technology

However, there are various fire sites in actual mines. Not all fire sites have extended tracks, or sometimes the tracks are blocked due to collapse, because the track wheels that match the mine tracks have their own defects. 1. The track wheels cannot turn , 2. The track wheel has an anti-derailment edge, which has caused the track wheel to be unsuitable for walking on normal roads. At this time, it is necessary for the staff to lift the fire truck off the track and directly transport it to the fire scene. At this time It is very time-consuming and labor-intensive, which seriously affects the fire-fighting time and will cause unimaginable consequences to the accident.
