Description

Technical Field

[0001] The utility model relates to the field of underground general equipment, in particular to a lifting explosion-proof lamp stand for an underground maintenance chamber. Background Art

[0002] Explosion-proof lighting lamps for coal mines are usually fixedly installed on the top plate or side of the tunnel. During installation and maintenance, workers need to work at heights, which is unsafe and inconvenient. At the same time, due to installation conditions, the position of the lighting lamp cannot be moved once it is installed. When it comes to specific operations, the lighting range in some places cannot meet the needs of the site. In this case, an external light source is required, which makes the work process cumbersome. There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a lifting explosion-proof lamp rack for an underground maintenance chamber that has a simple structure, can be quickly raised and lowered, extended and adjusted, and can flexibly reposition the position of the lighting lamp, thereby facilitating the inspection and maintenance of the explosion-proof lamp itself and coordinating with other operations, providing a better light source effect, and is easy to assemble.

[0004] The device includes a pulley, and the pulley is installed at a high position on the side wall of the chamber;

[0005] A support arm is hingedly provided at the lower part of the pulley, the support arm is a tube-in-tube structure, and an explosion-proof lamp is provided at the rear end of the support arm;

[0006] At the lower part of the support arm, a positioning rod is arranged in an array;

[0007] A suspension connection part is arranged on the support arm, a steel cable is arranged on the suspension connection part, and the steel cable passes through the pulley from top to bottom; a suspension component is arranged at the tail end of the steel cable, and the suspension component is suspended on the positioning rod.

[0008] The effect achieved by this is that by pulling the steel cable and fixing it on positioning rods of different heights, the height adjustment of the explosion-proof lamp can be achieved;

[0009] By adjusting the length of the support arm, the left and right position of the explosion-proof lamp can be adjusted. That is, the position adjustment of the explosion-proof lamp is achieved in the above-mentioned adjustment method.

[0010] The beneficial effects of the utility model are as follows: the utility model solves the problem that the explosion-proof lamp cannot be moved in the fixed installation in the prior art, and realizes the rapid positioning and adjustment of the explosion-proof lamp position, including the height and the horizontal setting position, through a simple structure, and thereby cooperates with different working conditions and the self-maintenance of the explosion-proof lamp. In particular, the equipment has a simple structure, is easy to assemble and maintain, and has great safety promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
