Description

Technical Field

[0001] This invention relates to an anchoring support and adjustment device for preventing deformation of rock slopes, belonging to the field of slope support technology. Background Technology

[0002] Rock slopes are slopes composed of rock. The stability of rock slopes depends on factors such as the relative relationship between the main structural planes of the rock mass and the slope dip, and the dip angle of the soil-rock interface. Based on rock mass strength, they can be classified as hard rock slopes, soft rock slopes, and weathered rock slopes. Based on rock mass structure, they can be classified as integral slopes, blocky slopes, layered slopes, fractured slopes, and loose-grained slopes. Their failure modes mainly include sliding, toppling, and collapse. To prevent slope failure and deformation, prestressed anchor rods are generally used for anchoring and support. One end of the prestressed anchor rod is connected to the support structure, and the other end is anchored within the rock and soil layer, with prestress applied. The frictional force at the anchored end forms pull-out resistance, bearing the structural tensile forces generated by soil and rock pressure, water pressure, buoyancy resistance, and overturning resistance, thus maintaining the stability of the rock and soil mass. Currently, to ensure the anchoring and support effect of prestressed anchor rods, it is usually necessary to adjust the prestress of the anchor rod by turning the anchor nut with a wrench.

[0003] Chinese patent document CN222791881U discloses a torque wrench that can adapt to prestressed anchor bolts of multiple sizes. The torque wrench can be used for construction of anchor bolts of different models. Only the corresponding anchor bolt adapter needs to be replaced to match anchor bolts of different diameters.

[0004] However, each time, it is necessary to change the corresponding anchor bolt adapter according to the anchor bolt model in order to tighten the anchor bolt nut to adjust the anchor bolt prestress. This has the disadvantages of low anchor bolt prestress adjustment efficiency and inconvenient operation of torque wrench. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an anchoring support adjustment device for preventing deformation of rock slopes.

[0006] This invention is achieved through the following technical solution: An anchoring support adjustment device for preventing deformation of rock slopes includes a shell and a nut fitting mechanism. One end of the shell is provided with a turning drive mechanism, and the turning drive mechanism extends into the shell. The other end of the shell is movably provided with a torque transmission mechanism, and the torque transmission mechanism extends into the shell. A torque detection component is provided inside the shell. The torque detection component is detachably connected to the turning drive mechanism and the torque transmission mechanism. The nut fitting mechanism is located outside the shell and is detachably connected to the torque transmission mechanism.

[0007] The levering drive mechanism includes a geared motor, a rotating shaft, and a connecting assembly.

The middle part of the second rotating shaft is rotatably connected to the housing, and one end of the second rotating shaft extends into the housing. The connecting assembly is located inside the housing and is fixedly connected to the end of the second rotating shaft that extends into the housing.

[0009] The connecting assembly includes a pad and a support plate. A bushing is fixedly mounted on one side of the pad, and multiple round rods are fixedly mounted on the other side. The round rods are arranged side by side, and a baffle is fixedly mounted on the end of each round rod away from the pad. The baffle is coaxial with the round rod, and the diameter of the baffle is larger than the diameter of the round rod. The support plate is fixedly connected to a rotating shaft one or a rotating shaft two. Multiple through holes are opened on the support plate at positions corresponding to the multiple round rods. The multiple through holes are fitted with the multiple round rods one by one with clearance, so as to realize the sliding connection between the support plate and the round rods. A support spring is fitted on each of the multiple round rods between the support plate and the pad.

[0010] The torque detection component is a torque sensor. A mounting base is fixed inside the housing. The mounting plate on the torque sensor is connected to the mounting base by screws. The input shaft of the torque sensor is inserted into the connecting component in the turning drive mechanism to realize torque transmission. The output shaft of the torque sensor is inserted into the connecting component in the torque transmission mechanism to realize torque transmission.

[0011] It also includes a display screen, which is mounted on the housing and electrically connected to the torque sensor.

[0012] The housing has an inspection port at a position corresponding to the torque detection component, and an inspection cover is detachably connected to the inspection port on the housing. Two handles are fixedly installed on the housing. The two handles are symmetrical, coaxial and arranged radially along the housing. Both handles are covered with rubber sleeves and are connected to the housing by reinforcing ribs.

[0013] The nut adapter mechanism includes a sliding sleeve, which is slidably connected to the second rotating shaft and realizes torque transmission. The sliding sleeve is provided with a limiting component to limit the relative position of the sliding sleeve and the second rotating shaft. The end of the sliding sleeve away from the second rotating shaft is provided with a nut adapter component.

[0014] The second rotating shaft has multiple toothed grooves along its length. The limiting component includes a U-shaped bracket and a toothed block. The U-shaped open end of the U-shaped bracket is fixedly connected to the sliding sleeve, and a square groove is provided in the middle of the U-shaped bracket. A square rod is provided on the toothed block, and the middle of the square rod is slidably connected to the square groove. A pull button is provided at the end of the square rod away from the toothed block. A limiting spring is fitted on the square rod between the U-shaped bracket and the toothed block. A sliding groove is provided on the sliding sleeve at a position corresponding to the toothed block. The toothed block is slidably connected to the U-shaped bracket and the sliding groove. Under the action of the spring force of the limiting spring, the toothed block is partially inserted into the toothed groove on the second rotating shaft.

[0015] The nut adapter assembly includes a pressure plate, a first washer, and several second washers. The first washer is fixedly connected to the pressure plate by multiple guide posts arranged in parallel. A hexagonal sleeve is fixedly provided on the side of the first washer away from the pressure plate. Several second washers are located between the pressure plate and the first washer. Several second washers are provided with multiple post holes. The multiple post holes on the second washer correspond to the multiple guide posts with clearance fit, so as to realize the sliding connection between the second washer and the multiple guide posts. A hexagonal sleeve is fixedly provided on the side of the second washer near the first washer. The shape and size of the hexagonal sleeve on the second washer near the pressure plate gradually decreases compared to the shape and size of the hexagonal sleeve on the second washer away from the pressure plate.

A return spring is fitted on the multiple guide posts between the pressure plate and the second washer adjacent to the pressure plate.

[0016] The beneficial effects of this invention are as follows: 1.

[0017] 2. Connecting components are provided at the ends of rotating shaft one and rotating shaft two that are close to each other. On the one hand, this facilitates quick connection of the input shaft of the torque sensor to rotating shaft one and the output shaft of the torque sensor to rotating shaft two, and ensures torque transmission. On the other hand, it also facilitates quick disassembly of the torque sensor.

[0018] 3. The distance between the support plate and the pad in the two connecting components can be reduced by pushing the pad to compress the support spring. On the one hand, this provides sufficient operating space for the input and output shafts of the torque sensor to be inserted into or disengaged from the bushings in the two connecting components, facilitating quick installation or disassembly of the torque sensor. On the other hand, it enables the two connecting components to provide axial compensation, reducing the axial installation accuracy requirements of the wrench drive mechanism, torque detection component, and torque transmission mechanism, while ensuring a continuous and reliable connection between the torque sensor and the connecting components, thereby improving the stability and reliability of torque transmission.

[0019] 4. The torque value of the anchor nut is detected by a torque sensor and displayed on a screen. This allows for quick adjustment of the anchor nut's tightness by referring to the torque value on the screen, thereby quickly adjusting the anchor prestress to the required value.

[0020] 5. The shape and size of the hexagonal sleeve one and multiple hexagonal sleeve two correspond one-to-one with the shape and size of various anchor bolt nuts of different models and specifications, so that the nut adapter assembly can be used to tighten various anchor bolt nuts of different models and specifications.

Detailed Implementation

[0023] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0024] like Figures 1 to 9 As shown, the rock slope anti-deformation anchoring support adjustment device of the present invention includes a housing 1 and a nut adapter mechanism. One end of the housing 1 is provided with a wrench driving mechanism, and the wrench driving mechanism extends into the housing 1. The other end of the housing 1 is movably provided with a torque transmission mechanism, and the torque transmission mechanism extends into the housing 1. The housing 1 is provided with a torque detection component 2. The torque detection component 2 is detachably connected to the wrench driving mechanism and the torque transmission mechanism. The nut adapter mechanism is located outside the housing 1 and is detachably connected to the torque transmission mechanism.

[0025] Specifically, the nut adapter mechanism is suitable for tightening various types and specifications of anchor nuts. When it is necessary to adjust the prestress of the anchor, first, the end of the nut adapter mechanism away from the torque transmission mechanism is put onto the anchor nut. Then, the torque of the tightening drive mechanism is transmitted to the nut adapter mechanism through the torque detection component 2 and the torque transmission mechanism, so as to drive the nut adapter mechanism to adjust the tightness of the anchor nut, thereby realizing the adjustment of the anchor prestress. At the same time, the torque detection component 2 detects the torque of tightening the anchor nut to ensure that the anchor prestress is adjusted to the required value.

[0026] Because the nut adapter mechanism is suitable for tightening various types and specifications of anchor nuts, it is not necessary to replace the nut adapter mechanism every time for different types and specifications of anchor nuts, which greatly improves the adjustment efficiency of anchor prestress and enhances the ease of operation and use of the device.

[0027] The turning drive mechanism includes a geared motor 11, a rotating shaft 5, and a connecting assembly 7. The geared motor 11 is located at one end of the housing 1, and the output shaft of the geared motor 11 extends into the housing 1. The rotating shaft 5 is located inside the housing 1, and one end of the rotating shaft 5 is connected to the output shaft of the geared motor 11. The connecting assembly 7 is located inside the housing 1 and is fixedly connected to the end of the rotating shaft 5 away from the geared motor 11.

[0028] Specifically, the rotating shaft 5 is rotatably connected to the housing 1 via a bearing. The geared motor 11 drives the connecting assembly 7 to rotate at a low speed via the rotating shaft 5.

[0029] The torque transmission mechanism includes a second rotating shaft 6 and a connecting assembly 7. The middle part of the second rotating shaft 6 is rotatably connected to the housing 1, and one end of the second rotating shaft 6 extends into the housing 1. The connecting assembly 7 is located inside the housing 1 and is fixedly connected to the end of the second rotating shaft 6 that extends into the housing 1.

[0030] Specifically, the second rotating shaft 6 is rotatably connected to the housing 1 via a bearing.

[0031] The connecting assembly 7 includes a pad 706 and a support plate 701. A bushing 707 is fixedly provided on one side of the pad 706, and multiple smooth round rods 703 are fixedly provided on the other side. The multiple smooth round rods 703 are arranged side by side, and a baffle 704 is fixedly provided on the end of the smooth round rod 703 away from the pad 706. The baffle 704 is coaxially arranged with the smooth round rod 703, and the diameter of the baffle 704 is larger than the diameter of the smooth round rod 703. The support plate 701 is fixedly connected to a rotating shaft 5 or a rotating shaft 6. Multiple through holes 702 are opened on the support plate 701 at positions corresponding to the multiple smooth round rods 703. The multiple through holes 702 and the multiple smooth round rods 703 are fitted with clearance to achieve a sliding connection between the support plate 701 and the smooth round rods 703. A support spring 705 is fitted on each of the multiple smooth round rods 703 between the support plate 701 and the pad 706.

[0032] Specifically, in the torque transmission mechanism, the support plate 701 within the connecting assembly 7 is fixedly connected to the end of the rotating shaft 5 furthest from the reduction motor 11, and the bushing 707 is inserted into the input shaft of the torque sensor to achieve torque transmission. In the torque transmission mechanism, the support plate 701 within the connecting assembly 7 is fixedly connected to the end of the rotating shaft 6 near the torque transmission mechanism, and the bushing 707 is inserted into the output shaft of the torque sensor to achieve torque transmission.

[0033] A connecting component 7 is provided at one end of each shaft 5 and shaft 6 that are close to each other. On the one hand, this facilitates quick connection of the input shaft of the torque sensor to shaft 5 and the output shaft of the torque sensor to shaft 6, and ensures torque transmission. On the other hand, it also facilitates quick disassembly of the torque sensor.

[0034] The distance between the support plate 701 and the pad 706 in the two connecting components 7 can be reduced by pushing the pad 706 to compress the support spring 705. On the one hand, this provides sufficient operating space for the input and output shafts of the torque sensor to be inserted into or disengaged from the bushings 707 in the two connecting components 7, facilitating quick installation or disassembly of the torque sensor. On the other hand, it enables the two connecting components 7 to provide axial compensation, reducing the axial installation accuracy requirements of the wrench drive mechanism, torque detection component 2, and torque transmission mechanism, while ensuring a continuous and reliable connection between the torque sensor and the connecting components 7, thereby improving the stability and reliability of torque transmission.

[0035] The torque detection component 2 is a torque sensor. A mounting base 4 is fixedly provided inside the housing 1. The mounting plate 3 on the torque sensor is connected to the mounting base 4 by screws. The input shaft of the torque sensor is inserted into the connecting component 7 in the turning drive mechanism to realize torque transmission. The output shaft of the torque sensor is inserted into the connecting component 7 in the torque transmission mechanism to realize torque transmission.

[0036] It also includes a display screen 10, which is mounted on the housing 1 and electrically connected to the torque sensor.

[0037] Specifically, the torque value of the anchor nut is detected by a torque sensor and displayed on the display screen 10. This allows for quick adjustment of the tightness of the anchor nut by referring to the torque value on the display screen 10, thereby quickly adjusting the anchor prestress to the required value.

[0038] The housing 1 has an inspection port 8 at a position corresponding to the torque detection component 2, and an inspection cover 9 is detachably connected to the inspection port 8 on the housing 1. Two handles 12 are fixedly provided on the housing 1. The two handles 12 are symmetrical, coaxial and arranged radially along the housing 1. Both handles 12 are covered with rubber sleeves 13 and are connected to the housing 1 by reinforcing plates 14 respectively.

[0039] Specifically, the inspection cover 9 is installed onto the housing 1 with screws, sealing the inspection port 8, which facilitates the installation and removal of the torque sensor. Two handles 12 are fixedly installed on the housing 1, allowing manual operation of the device to adjust the tightness of the anchor nut.

[0040] The nut adapter mechanism includes a sliding sleeve 16, which is slidably connected to the second rotating shaft 6 and realizes torque transmission. A limiting component 15 is provided on the sliding sleeve 16 to limit the relative position of the sliding sleeve 16 and the second rotating shaft 6. A nut adapter component 19 is provided at one end of the sliding sleeve 16 away from the second rotating shaft 6.

[0041] Specifically, the relative position of the sliding sleeve 16 and the rotating shaft 6 in the axial direction is limited by the limiting component 15.

[0042] The rotating shaft 6 has multiple toothed grooves 17 along its length direction; The limiting component 15 includes a U-shaped bracket 1501 and a toothed block 1504. The U-shaped opening end of the U-shaped bracket 1501 is fixedly connected to the sliding sleeve 16, and a square groove is provided in the middle of the U-shaped bracket 1501. A square rod 1502 is provided on the toothed block 1504. The middle part of the square rod 1502 is slidably connected to the square groove, and a pull button 1505 is provided at one end of the square rod 1502 away from the toothed block 1504. A limiting spring 1503 is fitted on the square rod 1502 between the U-shaped bracket 1501 and the toothed block 1504. A sliding groove 18 is provided on the sliding sleeve 16 at a position corresponding to the toothed block 1504. The toothed block 1504 is slidably connected to the U-shaped bracket 1501 and the sliding groove 18, and the toothed block 1504 is partially inserted into the toothed groove 17 on the rotating shaft 6 under the spring force of the limiting spring 1503.

[0043] Specifically, under the spring force of the limiting spring 1503, the toothed block 1504 partially engages with the toothed groove 17 on the rotating shaft 6 to lock the relative axial position of the sliding sleeve 16 and the rotating shaft 6. The pull button 1505 overcomes the spring force of the limiting spring 1503 and pulls the toothed block 1504 away from the rotating shaft 6. Once the toothed block 1504 separates from the toothed groove 17, the relative axial position of the sliding sleeve 16 and the rotating shaft 6 can be adjusted. Then, the pull button 1505 is released, and the toothed block 1504 again partially engages with the toothed groove 17 on the rotating shaft 6 under the spring force of the limiting spring 1503, thus locking the relative axial position of the sliding sleeve 16 and the rotating shaft 6 again.

[0044] The nut adapter assembly 19 includes a pressure plate 1901, a first washer 1903, and multiple second washers 1905. The first washer 1903 is fixedly connected to the pressure plate 1901 via multiple parallel guide posts 1902. A hexagonal sleeve 1904 is fixedly provided on the side of the first washer 1903 away from the pressure plate 1901. The multiple second washers 1905 are all located between the pressure plate 1901 and the first washer 1903. Each of the multiple second washers 1905 has multiple post holes 1906. The multiple post holes 1906 on the second washer 1905 correspond one-to-one with the multiple guide posts 1902, achieving a clearance fit between the second washer 1905 and the multiple guide posts 1902. The guide post 1902 is slidably connected. Hexagonal sleeves 1907 are fixedly provided on the side of multiple gaskets 1905 near the gasket 1903. The shape and size of the hexagonal sleeves 1907 on the gaskets 1905 near the pressure plate 1901 gradually decreases compared to the hexagonal sleeves 1907 on the gaskets 1905 far away from the pressure plate 1901. The shape and size of the hexagonal sleeve 1904 are larger than the shape and size of all the hexagonal sleeves 1907. A return spring 1908 is fitted on multiple guide posts 1902 between the pressure plate 1901 and the gaskets 1905 adjacent to the pressure plate 1901.

[0045] Specifically, the shape and size of the hexagonal sleeve 1904 and multiple hexagonal sleeves 1907 correspond one-to-one with the shape and size of various anchor nuts of different models and specifications, so that the nut adapter component 19 can be used to tighten various anchor nuts of different models and specifications.

[0046] When the nut adapter assembly 19 is fitted onto the anchor nut, the pressing device, under pressure, causes the hexagonal sleeve 1907, which is smaller in shape and size than the anchor nut, to move upward against the spring force of the return spring 1908, misaligning with the hexagonal sleeve 1904. Meanwhile, the hexagonal sleeve 1904 or hexagonal sleeve 1907, which matches the shape and size of the anchor nut, is fitted onto the anchor nut. Then, the reduction motor 11 is started. The reduction motor 11 transmits torque to the anchor nut through the rotating shaft 5, connecting assembly 7, torque sensor, connecting assembly 7, rotating shaft 6, sliding sleeve 16, pressure plate 1901, multiple guide posts 1902, corresponding gaskets 1903 or 2905, and corresponding hexagonal sleeves 1904 or 2907, thereby adjusting the tightness of the anchor nut until the anchor prestress is adjusted to the required value. Next, lift the device upwards to separate it from the anchor nut. Each washer 1905 and hexagonal sleeve 1907 will reset under the spring force of the return spring 1908.

[0047] The sliding sleeve 16 transmits torque to either the first washer 1903 or the second washer 1905 via the pressure plate 1901 and multiple guide posts 1902. The nut adapter assembly 19 has a robust and reliable structure and is not easily deformed.

A hexagonal sleeve (1904) is fixedly provided on the side of the first washer (1903) away from the pressure plate (1901). Several second washers (1905) are located between the pressure plate (1901) and the first washer (1903). Several second washers (1905) are provided with multiple post holes (1906). The multiple post holes (1906) on the second washer (1905) correspond one-to-one with the multiple guide posts (1902) for clearance fit, so that the second washer (1905) can be properly fitted. The device is slidably connected to multiple guide posts (1902). Several gaskets 2 (1905) are fixedly provided with hexagonal sleeves 2 (1907) on the side near gasket 1 (1903). The shape and size of the hexagonal sleeves 2 (1907) on the gaskets 2 (1905) near the pressure plate (1901) gradually decreases compared to the shape and size of the hexagonal sleeves 2 (1907) on the gaskets 2 (1905) far away from the pressure plate (1901). The shape and size of the hexagonal sleeve 1 (1904) is larger than the shape and size of all the hexagonal sleeves 2 (1907). The multiple guide posts (1902) are fitted with return springs (1908) between the pressure plate (1901) and the gaskets 2 (1905) adjacent to the pressure plate (1901).
