Pressure induction device of hydraulic prop

Abstract

The invention relates to a pressure induction device of a hydraulic prop, and belongs to the technical field of single hydraulic props. The pressure induction device is composed of a prop body, a general control device and a top cover device. The top cover device is installed at one end of the prop body, the general control device is fixedly installed on the prop body, and the general control device is composed of a first outer shell, a second outer shell, a protective cover, a first through hole, a second through hole, a third through hole, a display screen, a first key, a second key and a control center; the top cover device is composed of pressure sensors, a protective shell, a receiver and a transmitter, at least two pressure sensors are installed on the surface of the protective shell, and the pressure sensors are connected with the receiver through electric wires; and the receiver is connected with the transmitter through an electric wire, and the receiver and the transmitter are fixed in the protective shell. The situation that the hydraulic prop cannot be in contact with a tunnel cannot happen, the service life of the hydraulic prop cannot be influenced, and the life safety of workers is guaranteed; and the production expenses cannot be increased, and the usable area of the tunnel cannot be influenced.

Description

technical field [0001] The invention relates to a pressure sensing device, in particular to a pressure sensing device of a hydraulic prop, belonging to the technical field of a single hydraulic prop. Background technique [0002] The criss-cross mine tunnel is the most important item in coal mine safety inspection. In case of an accident, the mine tunnel is the only exit connecting to the outside world. The safety standard of the mine tunnel is also gradually raised. In order to prevent the mine tunnel from collapsing, the most effective The method is to use hydraulic props to support, and this method is generally adopted by coal mining enterprises, but in use, it is found that because the surface of the mine road is uneven, when the hydraulic prop is supporting, the top cover part will withstand the mine road. One part fails to touch the mine road, which will make the pressure of the hydraulic prop unbalanced, and the service life of the hydraulic prop will be greatly short...

[0002] The criss-cross mine tunnel is the most important item in coal mine safety inspection. In case of an accident, the mine tunnel is the only exit connecting to the outside world. The safety standard of the mine tunnel is also gradually raised. In order to prevent the mine tunnel from collapsing, the most effective The method is to use hydraulic props to support, and this method is generally adopted by coal mining enterprises, but in use, it is found that because the surface of the mine road is uneven, when the hydraulic prop is supporting, the top cover part will withstand the mine road. One part fails to touch the mine road, which will make the pressure of the hydraulic prop unbalanced, and the service life of the hydraulic prop will be greatly shortened for a long time. If the mine collapses, the hydraulic prop will not play any role, which will seriously affect the work The life safety of personnel, in order to solve this phenomenon, the number of hydraulic props used by coal mining enterprises in mine tunnels has increased by two to three times, production expenses have also greatly increased, and the area of ​​mine tunnels has also been greatly reduced, which seriously affects the entry and exit of staff. It is urgent to solve this problem
