Description

Technical Field

[0001] This utility model relates to the field of mine detection technology, and in particular to a mine roadway pressure detection device. Background Technology

[0002] The prior art patent CN209387182U discloses a mine pressure detection device, including a detection box body. A connecting seat is fixedly connected to the bottom of the detection box body, and a base is movably connected to the bottom of the connecting seat. A base plate is fixedly connected to the bottom of the base. Hydraulic cylinders are fixedly connected to both sides of the bottom of the inner surface of the detection box body. A sliding plate is fixedly connected between the output ends of the two hydraulic cylinders. A slider is fixedly connected to both sides of the sliding plate. A fixing plate is fixedly connected to both sides of the inner wall of the detection box body. This causes the vertical rod to move up and down on the inner surface of the through groove, so that multiple anti-slip circular plates abut against the rock layer at multiple angles. A certain elastic pressure is generated by the return spring, which installs the anti-slip circular plates on the rock layer at the corresponding angle, effectively improving the anti-slip performance.

[0003] The device is installed in the rock strata to detect the pressure in the mine roadway. However, rocks often fall on the rock strata in the mine, and the device body is not equipped with a corresponding protective structure. During use, it is easy to be damaged by the impact of falling rocks. Therefore, a mine roadway pressure detection device is needed to meet the usage requirements. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example:

[0024] like Figure 1-6 As shown, this embodiment provides a mine roadway pressure detection device, including a base plate 1, a base 2 fixedly installed on the base plate 1, a pressure detection device body 3 set on the base 2, a guide rail 4 set above the base plate 1, a sleeve 5 slidably installed in the guide rail 4, a protective plate 6 fixedly installed on the sleeve 5, an adjustable protective plate 7 set on the protective plate 6, a fixing mechanism 8 set on the protective plate 6 and the adjustable protective plate 7, a protective plate integration mechanism 9 set on the protective plate 6, a guide rail mounting mechanism 10 set on the base plate 1 and the guide rail 4, and a strip support seat 11 fixedly installed on the base plate 1;

[0025] First, the base plate 1, base 2, and pressure detection device body 3 are installed on the rock strata of the mine roadway. Then, the height of the pressure detection device body 3 is adjusted according to requirements, and the pressure in the mine roadway is detected through the pressure detection device body 3. This process is existing technology, and the specific principles and processes are not detailed here. Next, the guide rail 4 is installed on the base plate 1 through the guide rail mounting mechanism 10. Then, a set of protective plates 6 is pushed along the guide rail 4 by the clamping sleeve 5 and moved closer together. The protective plates 6 are fixed together by the protective plate integration mechanism 9. The adjustable protective plate 7 is adjusted according to the height of the pressure detection device body 3, and the position of the adjustable protective plate 7 is locked by the fixing mechanism 8. The protective plate 6 and the adjustable protective plate 7 together form a protective cover that protects the pressure detection device body 3, preventing damage from long-term impacts from falling rocks. The strip support 11 provides stable support for the guide rail 4.

[0026] In this embodiment of the utility model, specifically, the fixing mechanism 8 includes a screw hole 83 that passes through the protective plate 6 and the adjusting protective plate 7, a fixing screw 82 is screwed into the screw hole 83, and a screw block 81 is fixedly installed at the end of the fixing screw 82;

[0027] To lock the position of the adjusted protective plate 7, after adjusting the position of the protective plate 7, align the screw holes 83 on the protective plate 6 and the adjusted protective plate 7, and then screw the fixing screw 82 into the screw hole 83 using the screw block 81 to lock the position of the adjusted protective plate 7.

[0028] In this embodiment of the utility model, specifically, there is a set of protective plates 6. Each set of protective plates 6 is fixedly installed with a pin 91 and a sleeve 92. The pin 91 is inserted into the sleeve 92. An abutment block 93 is slidably installed in the pin 91. A first telescopic spring 94 and a first guide telescopic rod 95 are fixedly installed at the bottom of the abutment block 93. The other ends of the first telescopic spring 94 and the first guide telescopic rod 95 are fixedly installed in the pin 91.

[0029] In order to lock a set of protective plates 6 together, the set of protective plates 6 can move and move closer to each other so that the pin 91 passes through the sleeve 92. When the abutment block 93 passes through the sleeve 92, under the action of the first telescopic spring 94, the abutment block 93 can pop up and abut against the sleeve 92, thereby locking a set of protective plates 6 together. The first guide telescopic rod 95 can guide the movement of the abutment block 93.

[0030] In this embodiment of the utility model, specifically, the guide rail mounting mechanism 10 includes a disassembly base 101 fixedly mounted on the base plate 1, a bracket 102 fixedly mounted on the bottom of the guide rail 4, a locking plate 103 movably mounted inside the disassembly base 101, the locking plate 103 being snapped into the bracket 102, a second telescopic spring 104 and a second guide telescopic rod 105 fixedly mounted inside the disassembly base 101, and the other ends of the second telescopic spring 104 and the second guide telescopic rod 105 being fixedly mounted on the locking plate 103;

[0031] To avoid affecting the adjustment of the pressure detection device body 3, the guide rail 4 is installed above the base plate 1 after adjustment. After the height of the pressure detection device body 3 is adjusted, the insert bracket 102 is directly inserted into the front of the disassembly base 101. The insert bracket 102 will squeeze the clamping plate 103 into the disassembly base 101. When the clamping plate 103 coincides with the hole on the insert bracket 102, the clamping plate 103 will be driven into the insert bracket 102 by the action of the second telescopic spring 104, thus completing the installation of the guide rail 4. The second guide telescopic rod 105 can guide the movement of the clamping plate 103.

[0032] In this embodiment of the utility model, a tube 107 is fixedly installed on the base plate 1, a circular plate 106 is fixedly installed on the bottom of the guide rail 4, a connector 108 is fixedly installed on the bottom of the circular plate 106, a compression spring 109 is fixedly installed inside the tube 107, and the connector 108 is inserted into the tube 107 and abuts against the compression spring 109.

[0033] To position the insert 102 and facilitate its ejection, the connector 108 on the circular plate 106 is aligned with and inserted into the insert cylinder 107. At this time, the insert 102 can be inserted into the front of the disassembly base 101, and the compression spring 109 is also compressed by the connector 108. When it is necessary to remove the protective plate 6 and the adjusting protective plate 7, the locking plate 103 is pressed into the disassembly base 101. Under the action of the compression spring 109, the insert 102 can be ejected upward, facilitating the disassembly of the protective plate 6 and the adjusting protective plate 7.

[0034] Working principle: In use, align the connector 108 on the circular plate 106 with the insert cylinder 107 and insert it. At this time, the insert bracket 102 can be inserted into the front side of the disassembly base 101. The insert bracket 102 will squeeze the clamping plate 103 into the disassembly base 101. When the clamping plate 103 coincides with the hole on the insert bracket 102, the clamping plate 103 will be driven into the insert bracket 102 by the action of the second telescopic spring 104. The guide rail 4 can be installed above the base plate 1. Then, the clamping sleeve 5 pushes a set of protective plates 6 to move on the guide rail 4 and move closer to each other. The movement and close proximity of the set of protective plates 6 can allow the pin 91 to pass through the insert sleeve 92. When the abutment block 93 passes through the insert sleeve 92, Under the action of the first telescopic spring 94, the abutment block 93 can be ejected upward and pressed against the insert 92, thereby locking a set of protective plates 6 together. The protective plate 7 can be adjusted according to the height of the pressure detection device body 3. After adjusting the position of the protective plate 7, the screw holes 83 on the protective plate 6 and the adjusting protective plate 7 are aligned. Then, the fixing screw 82 is screwed into the screw hole 83 by the screw block 81, thereby locking the position of the adjusting protective plate 7. The protective plate 6 and the adjusting protective plate 7 together can protect the pressure detection device body 3 and prevent the pressure detection device body 3 from being damaged by falling rocks over a long period of time.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
