Coal mine roadway displacement automatically monitoring device

Abstract

The invention discloses a coal mine roadway displacement automatically monitoring device. The coal mine roadway displacement automatically monitoring device comprises a base, and the lower surface ofthe base is fixedly provided with fixing teeth, through which the entire coal mine roadway displacement automatically monitoring device can be fixed stably inside a coal mine roadway; the fixing teethcan grip the ground firmly so that the monitoring efficiency of the coal mine roadway displacement automatically monitoring device can be enhanced; a rotating motor drives a double screw to rotate; mounting bases inside two moving chambers can move in opposite directions along the double screw; monitoring units connected to the mounting bases through connecting rods can monitor both side walls ofthe coal mine roadway; when air cylinders are opened, the monitoring units fixedly mounted at the output ends of the air cylinders can monitor the top wall inside the coal mine roadway, settlement sensors and pressure sensors are directly fixed onto the inner walls of the coal mine roadway to in real time monitor whether settlement cracks exist in the coal mine roadway; data collected by the sensors can be automatically transmitted to monitoring personnel, so that monitoring the coal mine roadway can be fully achieved.

Description

technical field The invention relates to the field of coal mine roadway safety monitoring equipment, in particular to an automatic monitoring device for coal mine roadway surface displacement. Background technique There are many safety hazards in the process of coal mine excavation, among which the safety of coal mine roadway is one of them. The safety of coal mine roadway directly affects the coal mining work. In the process of coal mining, it is necessary to monitor the safety of the coal mine roadway in real time. Some current monitoring equipment cannot monitor the roadway accurately in real time, and the current roadway is of various sizes, which requires that the monitoring device must be able to adjust. In order to adapt to various lanes. Contents of the invention The object of the present invention is to provide an automatic monitoring device for the surface displacement of coal mine roadway, so as to solve the problems raised in the above-mentioned background te...
