Description

Technical Field

[0001] The utility model relates to the technical field of geological detection devices, and particularly relates to a coal mine geological detection device for geological surveying. Background Technique

[0002] The coal mine geological detection device is an important part of coal mine exploitation in the prior art. Geological detection can accurately master key information such as the geological structure and coal seam occurrence state in the coal mine area, help judge the stability of the coal seam, gas outburst situation and ground pressure deformation characteristics, so as to early warn the occurrence of coal mine geological disasters and provide a scientific basis for safe production.

[0003] When the coal mine geological detection device in the prior art conducts settlement detection of the mine, generally the total station monitoring method is adopted: using high-precision measuring equipment such as total stations, through means such as laser beams and photoelectric trackers, to continuously and highly accurately measure the surface of the mine in real time, and monitor parameters such as the settlement, deformation and displacement of the mine. Or the GPS monitoring method: using the global positioning system (GPS) technology to accurately measure the position and elevation of the surface change of the mine, realize real-time monitoring and precise positioning, and provide high-precision data for mine settlement monitoring.

[0004] However, the above devices cannot extend into the mine to detect parameters such as the deformation and displacement of the mine, and can only reduce the surface detection. Therefore, in view of this problem, a coal mine geological detection device for geological surveying is needed for improvement. Content of the Utility Model

The pressure detection device is electrically connected to the control box through a connection cable. Through the connection cable, the pressure detection data of the shaft detected by the pressure detection device can be transmitted to the control box in real time, and then the detection data is transmitted to the control terminal through the control box, so that the staff can conveniently obtain these detection data.

[0008] Preferably, a hook is fixedly arranged at the lower end of the connection cable, and a lifting lug is fixedly arranged at the upper end of the electric push rod. The hook and the lifting lug are engaged with each other, and the connection cable and the electric push rod can be conveniently and quickly fixed together through the hook and the lifting lug.

[0009] Preferably, a limiting frame is fixedly arranged on the outer surface of the side plate above the fixed pulley. The limiting frame can prevent the cable from falling off the upper surface of the fixed pulley.

[0010] Preferably, a limiting frame is fixedly arranged on the outer surface of the side plate above the fixed pulley. The limiting frame can prevent the cable from falling off the upper surface of the fixed pulley.

[0011] Preferably, a motor is fixedly arranged on the upper end of the bottom plate on one side of the winding drum. The output shaft end of the motor is in transmission connection with the rotating shaft where the winding drum is located through a coupling.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1.

In this way, the detection effect of the device can be improved.

[0014] 2. In the present utility model, the motor drives the winding drum to rotate. By rotating the winding drum to release or wind the connection cable, the whole detection mechanism can be driven to move up and down inside the shaft, so as to drive the detection mechanism to be at the target position in the shaft. In this way, the detection flexibility of the device is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

An electric push rod 7 is arranged inside the shaft, a movable head 8 is fixedly arranged at the movable end of the electric push rod 7, a plurality of connecting rods 9 are evenly movably arranged on the outer surface of the electric push rod 7 through a rotating shaft, one end of the connecting rod 9 far from the electric push rod 7 is movably arranged with a tension rod 10 through a rotating shaft, a transmission rod 11 is movably arranged on the outer surface of the movable head 8 through a rotating shaft, and one end of the transmission rod 11 close to the tension rod 10 is movably connected with the tension rod 10 through a rotating shaft, and a pressure detection device 12 is fixedly arranged on the outer surface of the tension rod 10.

[0023] A control box 13 is fixedly provided on the surface of the side plate 4 on one side of the fixed roller. The pressure detection device 12 is electrically connected to the control box 13 via a connecting cable 6. The connecting cable 6 can transmit the pressure detection data of the vertical shaft by the pressure detection device 12 to the control box 13 in real time. The control box 13 then transmits the detection data to the control terminal, making it convenient for staff to obtain the detection data.

[0024] A hook 14 is fixedly provided at the lower end of the connecting cable 6, and a lug 15 is fixedly provided at the upper end of the electric push rod 7. The hook 14 and the lug 15 engage with each other, and the connecting cable 6 and the electric push rod 7 can be fixed together conveniently and quickly by the hook 14 and the lug 15;

[0025] A limit frame 16 is fixedly provided on the outer surface of the side plate 4 at the upper end of the fixed pulley 5, and the limit frame 16 can prevent the cable from falling off the upper end surface of the fixed pulley 5;

[0026] A winding drum 17 is movably provided at the upper end of the base plate 1 on one side of the column 3 via a rotating shaft. The connecting cable 6 is wound around the outer surface of the winding drum 17. The rotation of the winding drum 17 to release the connecting cable 6 or to wind the connecting cable 6 can drive the entire detection mechanism to move up and down inside the shaft, thereby driving the detection mechanism to the target position of the shaft.

[0028] Working principle: When the device is used, the detection mechanism is placed inside the shaft, and then the electric push rod 7 is extended, so that the tensioning plate can be pushed to open to the surroundings through the transmission rod 11, and then the pressure detection device 12 is squeezed firmly and pressed against the inner side wall of the shaft. Then the pressure detection device 12 can transmit the detection data to the control box 13 through the connecting cable 6, and then the control box 13 transmits the detection data to the control terminal, so that the staff can easily obtain these detection data; if the entire mine is normal and there is no change, the detection data of the pressure detection device 12 should not change significantly at the time, and if the mine is deformed or collapsed, the detection data of the pressure detection data will disappear or increase, which means that the mine is abnormal and needs to be detected in time. In this way, a shaft is opened on the surface of the mine, and then a pressure detection device 12 is set in the shaft. Then, by detecting whether the shaft 2 is deformed, it is judged whether the entire mine is deformed or settled. In this way, the detection effect of the device can be improved.

[0029] When the device is in use, the motor 18 drives the winding drum 17 to rotate. By the rotation of the winding drum 17, the connecting cable 6 is released or wound, and the entire detection mechanism can be driven to move up and down inside the shaft, so that the detection mechanism can be driven to the target position in the shaft. In this way, the device has high detection flexibility.
