Description

Technical Field

[0001] This utility model relates to the field of ground pressure detection technology, specifically a support device for ground pressure detection equipment. Background Technology

[0002] Non-coal mining areas account for a large proportion of mining development, especially in recent years with social development and increasing investment in mining areas. However, safety issues have become increasingly prominent during this development process. Many mines have numerous goaf areas. Since goaf areas and working areas are often located together, ground pressure monitoring equipment is needed to detect ground pressure and prevent disasters. Ground pressure monitoring equipment is typically installed stably with the assistance of support devices.

[0003] Based on the above, the inventors have discovered the following problems: In actual use, the support device and the ground pressure detection equipment are generally rigidly supported, which cannot adapt to uneven rock surfaces during the detection process, thus reducing the practicality of the support device.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a support device for ground pressure detection equipment in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a support device for ground pressure detection equipment to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A support device for a ground pressure detection equipment includes a lifting assembly, a telescopic assembly, and an angle adjustment assembly. The telescopic assembly is disposed outside the lifting assembly, and the angle adjustment assembly is disposed outside the telescopic assembly. The lifting assembly is used to adjust the height of the ground pressure detection device, and the telescopic assembly is used to allow the detection end of the ground pressure detection device to fit against the rock wall to be detected. The angle adjustment assembly is used to adjust the angle of the ground pressure detection device. The angle adjustment assembly includes a connecting seat, a first universal joint is installed at one end of the connecting seat, a connecting rod is installed at the end of the first universal joint away from the connecting seat, a second universal joint is installed at the end of the connecting rod away from the first universal joint, a first mounting seat is installed at the end of the second universal joint away from the connecting rod, a second mounting seat is sleeved on the outside of the first mounting seat, and the ground pressure detection device is installed at the end of the second mounting seat away from the first mounting seat.

[0008] Furthermore, the longitudinal section of the first mounting base is T-shaped, and first screw holes are provided on both outer sides of the first mounting base. The second mounting base is provided with a second screw hole near the first screw hole, and fastening bolts are threadedly connected between adjacent first screw holes and second screw holes.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperative use of the first mounting base, the second mounting base, and the fastening bolts, the first mounting base and the second mounting base are fixed together by the fastening bolts, thereby facilitating the quick assembly and disassembly of the first mounting base and the second mounting base, and thus facilitating the subsequent maintenance of the ground pressure detection device by the operators.

[0010] Furthermore, the telescopic assembly includes a fixed base with a cavity inside. One end of the fixed base has a circular hole, and a telescopic rod is provided inside the circular hole. One end of the telescopic rod is fixedly connected to the end of the connecting base away from the first universal joint, and the telescopic rod has scale lines on its outside.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting scale lines on the outside of the telescopic rod, it is convenient for users to read the extension amount of the telescopic rod through the scale lines. By setting the telescopic rod, the telescopic rod in the fixed seat can extend outward or retract inward, thereby adjusting the distance between the detection end of the ground pressure detection device and the rock wall, ensuring that the detection end is in close contact with the rock wall, thereby obtaining accurate ground pressure data.

[0012] Furthermore, a fixing plate is installed inside the cavity, and a screw is rotatably connected to one side of the fixing plate. A block is threadedly connected to the outside of the screw, and the outer wall of the block slides against the inner wall of the cavity. The block is fixedly connected to the end of the telescopic rod away from the connecting seat on the side away from the fixing plate. An installation cavity is opened inside the telescopic rod, and the inner wall of the installation cavity is provided with several threads. The screw extends through the telescopic rod into the cavity at the end away from the fixing plate and is threadedly connected to the telescopic rod.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since the screw is threadedly connected to the block and the telescopic rod, and the outer wall of the block is slidingly fitted with the inner wall of the cavity, when the screw rotates, the block and the telescopic rod connected to its external threads can only extend and retract axially under the action of the sliding fit between the outer wall of the block and the inner wall of the cavity.

[0014] Furthermore, a second servo motor is installed on one side of the inner wall of the cavity, and the output end of the second servo motor is connected to the screw via a transmission.

[0015] The advantage of adopting the above-mentioned further solution is that by setting a second servo motor, it is easier to drive the screw to rotate when the second servo motor is working.

[0016] Furthermore, the lifting assembly includes a base plate, a first column is installed at the bottom end of the base plate, a second column is installed at the top end of the base plate, a movable block is slidably connected inside the second column, a movable sleeve 17 is sleeved on the outside of the second column, sliding grooves are provided on all four sides of the second column, and sliders are slidably connected inside the four sliding grooves. The outer sides of the sliders are fixedly connected to the inner wall of the movable sleeve and the outer wall of the movable block, respectively. One side of the outer wall of the movable sleeve is fixedly connected to the end of the fixed seat away from the connecting seat.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting the slide and slider, the movement direction of the moving sleeve is restricted, so that it can only move vertically along the second column, which effectively prevents tilting or shaking during the lifting process and ensures the stability of the ground pressure detection device at different heights. At the same time, the slider is fixedly connected to the moving sleeve and the moving block respectively to form a multi-faceted support structure, which disperses the force during the lifting process and improves the overall structure's load-bearing capacity and deformation resistance.

[0018] Furthermore, a drive box is installed at the upper end of the second column, and a take-up roller is rotatably connected inside the drive box. A steel wire rope is wound around the outside of the take-up roller. One end of the steel wire rope passes through the drive box and the second column, extends into the interior of the second column, and is fixedly connected to the upper end of the moving block. A first servo motor is installed on one side of the outer wall of the drive box, and the output end of the first servo motor is connected to the take-up roller for transmission.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting a first servo motor, when the first servo motor is working, it drives the winding roller to rotate, and the winding roller winds up and down the wire rope, so that the moving block and the moving sleeve connected to the moving block through the slider rise or fall under the action of the wire rope, and detect different positions of the rock wall, thereby improving the safety and convenience of operation.

[0020] Furthermore, threaded holes are provided at all four corners of the base plate.

[0021] The advantage of adopting the above-mentioned further solution is that, by setting the threaded hole, it is convenient for the operator to fix the support device to different bases or the ground with bolts.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The ground pressure detection equipment uses a support device and a lifting component to adjust the vertical height of the ground pressure detection device, making it suitable for rock wall detection scenarios at different heights. Rock wall surfaces are often uneven, and the telescopic component can adjust the distance between the detection end of the ground pressure detection device and the rock wall, ensuring that the detection end of the ground pressure detection device is in close contact with the detection position, avoiding errors in detection data due to gaps. Through the cooperation of the first universal joint, the second universal joint, and the connecting rod, the ground pressure detection device can be freely rotated in multiple dimensions such as pitch, tilt, and rotation, adapting to any tilt angle or curved surface of the rock wall, ensuring comprehensive coverage of detection data. Since the first mounting base is fitted with a second mounting base, and the first and second mounting bases are fixed together by fastening bolts, the ground pressure detection device can be quickly assembled and disassembled. Under different geological conditions, the ground pressure detection equipment suitable for hard rock or soft rock can be quickly switched. Attached Figure Description

By setting a scale line on the outside of the telescopic rod 25, it is easy for the user to read the extension amount of the telescopic rod 25 through the scale line.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5This utility model provides a technical solution: the lifting assembly 1 includes a base plate 11, a first column 12 is installed at the bottom end of the base plate 11, a second column 13 is installed at the upper end of the base plate 11, a movable block 14 is slidably connected inside the second column 13, a movable sleeve 17 is sleeved on the outside of the second column 13, and each of the four sides of the second column 13 has a sliding groove 15, and each of the four sliding grooves 15 has a sliding block 16 slidably connected inside. The outer two sides of the sliding block 16 are respectively fixedly connected to the inner wall of the movable sleeve 17 and the outer wall of the movable block 14. One side of the outer wall of the movable sleeve 17 is fixedly connected to the end of the fixed seat 21 away from the connecting seat 31. A drive box 18 is installed at the upper end of the second column 13, and a winding roller 19 is rotatably connected inside the drive box 18. A steel wire rope 110 is wound around the outside of the winding roller 19. The end extends through the drive box 18 and the second column 13 into the interior of the second column 13 and is fixedly connected to the upper end of the moving block 14. A first servo motor 111 is installed on one side of the outer wall of the drive box 18. The output end of the first servo motor 111 is connected to the winding roller 19 for transmission. Threaded holes are provided at the four corners of the base plate 11. By setting the first servo motor 111, when the first servo motor 111 is working, it drives the winding roller 19 to rotate. The winding roller 19 winds up and unwinds the wire rope 110, so that the moving block 14 and the moving sleeve 17 connected to the moving block 14 through the slider 16 rise or fall under the action of the wire rope 110, so as to detect different positions of the rock wall, improve the safety and convenience of operation. The setting of the threaded holes makes it easy for the operator to fix the support device to different bases or the ground with bolts.

[0035] Specifically, the working principle of the support device for this type of ground pressure detection equipment is as follows: During use, the operator first digs a pit in the ground near the detection location and inserts the first column 12 into the pit. Then, the support device is fixed to different bases or the ground using bolts. When the first servo motor 111 works, it drives the winding roller 19 to rotate. The winding roller 19 winds up and unwinds the wire rope 110, causing the moving block 14 and the moving sleeve 17 connected to the moving block 14 via the slider 16 to rise or fall under the action of the wire rope 110, detecting different positions on the rock wall. When the second servo motor 26 works, it drives the screw 23 to rotate, causing the externally threaded block 24 and the telescopic rod 25 to only extend and retract axially under the sliding cooperation between the outer wall of the block 24 and the inner wall of the cavity. The telescopic rod 25 inside the fixed seat 21 can extend outwards or retract inwards. The distance between the detection end of the ground pressure detection device 310 and the rock wall is adjusted to ensure a tight fit between the detection end and the rock wall, thereby obtaining accurate ground pressure data. By setting scale lines on the outside of the telescopic rod 25, the user can easily read the extension amount of the telescopic rod 25 through the scale lines. Through the cooperation of the first universal joint 32, the second universal joint 34 and the connecting rod 33, the ground pressure detection device 310 can be freely rotated in multiple dimensions such as pitch, tilt and rotation, which can adapt to any tilt angle or curved surface of the rock wall and ensure comprehensive coverage of detection data. Since the first mounting base 35 is fitted with the second mounting base 36, and the first mounting base 35 and the second mounting base 36 are fixed by fastening bolts 39, the ground pressure detection device 310 can be quickly assembled and disassembled.
