Anchored pier anti-slide slope protection device

Abstract

This invention provides an anchored pier slope protection device for landslide prevention, relating to the technical field of support devices, including: a fixing frame and an anchor pier assembly. When the adjusting component is adjusted to its maximum adjustment range and still fails to achieve anchor cable clamping, adjustment can be made by rotating a threaded rod. Rotating the threaded rod drives the compression plate to move downwards, achieving anchor cable clamping and tensioning. In summary, it can achieve anchor cable tensioning and allows adjustment through multiple structures. Even if one structure is damaged, adjustment can still be made. This solves the problem that currently, after anchor cable fixation, the anchor cable easily loosens after a period of use, reducing the anchor cable's fixing effect and thus affecting the support effect. Furthermore, it cannot achieve multiple adjustments through structural improvements to ensure that adjustment can still be made even when one adjustment reaches its upper limit or is damaged.

Description

Technical Field

[0001] This invention relates to the field of support device technology, and in particular to an anchored pier anti-slide slope support device. Background Technology

[0002] The Mengdigou Hydropower Station is the fifth cascade in the seven-stage development plan for the middle reaches of the Yalong River. It connects with the Lenggu cascade upstream and the Yangfanggou cascade downstream. The hub area is located on the main stream of the Yalong River at the border of Ganzi Prefecture and Liangshan Prefecture in Sichuan Province. The reservoir area involves Jiulong County, Kangding City, Yajiang County in Ganzi Prefecture and Muli County in Liangshan Prefecture. Support devices are required for the slope protection of the hydropower station.

[0003] Currently, after being fixed by anchor cables, the anchor cables are prone to loosening after a period of use. At this time, the fixing effect of the anchor cables will be reduced, which will affect the support effect. It is not possible to achieve multiple adjustments through structural improvements to ensure that adjustments can still be made when one adjustment reaches the adjustment limit or is damaged. Summary of the Invention

[0004] In view of this, the present invention provides an anchored pier anti-slide slope support device, which solves the problem that after the anchor cable is fixed, it is easy for the anchor cable to loosen after a period of use. At this time, the fixing effect of the anchor cable will be reduced, which will affect the support effect. It is not possible to achieve multiple adjustments through structural improvements to ensure that adjustments can still be made when one adjustment reaches the adjustment limit or is damaged.

[0005] The purpose and effectiveness of the anchored pier anti-slide slope support device of the present invention are achieved by the following specific technical means:

[0006] This invention provides an anchored pier anti-slide slope support device, specifically including: a fixing frame and an anchored pier assembly;

[0007] The fixing frame is equipped with four first fixing components, and there are a total of four anchor pier components. All four anchor pier components are installed on the slope, and four support blocks are welded on the fixing frame.

[0008] Furthermore, the first fixing component consists of a first rotating shaft, a fixing seat, a first ground nail, and a second ground nail. The first rotating shaft is rotatably connected to the fixing frame, and a fixing seat is welded onto each of the first rotating shafts.

[0009] Furthermore, each of the aforementioned fixing bases is welded with two first ground nails, both of which are inserted into the soil.

[0010] Furthermore, the bottom end face of the fixing frame is welded with a second ground nail in a rectangular array. When the first ground nail is inserted into the soil, the second ground nail is inserted into the soil simultaneously. When fixing, the first ground nail can be directly fixed to the soil. After the first ground nail is inserted into the soil, the second ground nail is inserted into the soil simultaneously under the drive of the fixing frame.

[0011] Furthermore, the anchor assembly consists of an anchor body, a third ground nail, a second rotating shaft, a connecting seat, a worm gear, a rotating frame, a worm, an adjusting component, and ball bearings. There are four anchor bodies in total, and the four anchor bodies are placed on the slope in pairs. Two anchor bodies are located on the left side of the fixing frame, and the other two anchor bodies are located on the right side of the fixing frame.

[0012] Furthermore, each of the aforementioned piers is welded with a third ground nail, and all four third ground nails are inserted into the soil; each of the aforementioned piers is rotatably connected with a second shaft.

[0013] Furthermore, the second rotating shaft is a cylindrical rod structure, and each second rotating shaft has a limiting sliding connection with a connecting seat that is connected to the anchor cable. An anchor cable is connected between the two connecting seats on the left and right sides, and the anchor cable is connected to the support block.

[0014] Furthermore, the support block is a rectangular block structure, and a groove is provided at the center of the top surface of the support block. The groove is a semi-cylindrical groove structure, and the anchor cable is engaged inside the groove.

[0015] Furthermore, a worm gear is welded onto the second rotating shaft; a rotating frame is welded onto the pier body, and a worm is rotatably connected to the rotating frame, with the worm meshing with the worm gear.

[0016] Furthermore, the second rotating shaft is threaded, and an adjusting component is threadedly connected to the second rotating shaft. One end of the adjusting component has a circular array of balls, which contact the connecting seat. When the anchor cable needs adjustment, the worm gear can be rotated directly. When the worm gear is rotated, the worm wheel and the second rotating shaft rotate under the drive of the worm gear. When the second rotating shaft rotates, it drives the connecting seat to rotate, thus tensioning the anchor cable. At this time, the tensioned anchor cable can press the fixing frame tightly. When the worm gear is damaged and cannot be adjusted, the adjusting component can be rotated directly. When the adjusting component rotates, it compresses the connecting seat. By compressing the connecting seat backward, the anchor cable can be tensioned. During rotation, because the rear end of the adjusting component has a circular array of balls, which contact the connecting seat, adjustment is convenient and quick.

[0017] Furthermore, an auxiliary component is installed on one of the inner connecting seats. The auxiliary component consists of a threaded rod and a pressing plate. The threaded rod is threadedly connected to one of the inner connecting seats, and a pressing plate is rotatably connected to the lower end of the threaded rod. The pressing plate is in contact with the anchor cable. When the adjusting member is adjusted to the maximum adjustment range, the anchor cable can be tightened. At this time, the threaded rod can be rotated. When the threaded rod is rotated, the pressing plate can be moved downward under the drive of the threaded rod. When the pressing plate moves downward, the anchor cable can be tightened, and the anchor cable can be tensioned. Beneficial effects

[0018] When anchor cable tensioning is required, it can first be adjusted by rotating the worm gear. When the worm gear is rotated, the worm wheel and the second shaft rotate under the drive of the worm gear. When the second shaft rotates, it can drive the connecting seat to rotate. When the connecting seat rotates, the anchor cable can be tensioned.

[0019] Secondly, when the worm gear is damaged and cannot be adjusted, the adjusting part can be rotated directly. When the adjusting part rotates, the connecting seat can be squeezed. The anchor cable can be tensioned by squeezing the connecting seat backward.

[0020] Finally, when the adjustment component is adjusted to the maximum adjustment range and the anchor cable can still be tightened, it can be adjusted by rotating the threaded rod. When the threaded rod is rotated, the pressing plate can be moved downward under the drive of the threaded rod. When the pressing plate moves downward, the anchor cable can be tightened, and the anchor cable can be tensioned. In summary, the anchor cable can be tensioned and can be adjusted through multiple structures. Even if one structure is damaged, it can still be adjusted.

[0021] During the fixing process, the second ground nail can be fixed at the same time as the first ground nail, resulting in high fixing efficiency. Attached Figure Description

[0036] Example 1

[0037] Please refer to Figures 1 to 8 :

[0038] This invention proposes an anchored pier anti-slide slope support device, comprising: a fixing frame 1 and an anchored pier assembly 3;

[0039] Four first fixing components 2 are installed on the fixing frame 1, and there are four anchor pier components 3 in total. All four anchor pier components 3 are installed on the slope. Four support blocks 101 are welded on the fixing frame 1.

[0040] The first fixing component 2 consists of a first rotating shaft 201, a fixing seat 202, a first ground nail 203, and a second ground nail 204. The first rotating shaft 201 is rotatably connected to the fixing frame 1, and a fixing seat 202 is welded onto each first rotating shaft 201.

[0041] Each fixing base 202 has two first ground nails 203 welded on it, and both first ground nails 203 are inserted into the soil.

[0042] The bottom surface of the fixing frame 1 is welded with a second ground nail 204 in a rectangular array. When the first ground nail 203 is inserted into the soil, the second ground nail 204 is inserted into the soil simultaneously. When fixing, the first ground nail 203 can be directly fixed to the soil. After the first ground nail 203 is inserted into the soil, the second ground nail 204 is inserted into the soil simultaneously under the drive of the fixing frame 1.

[0043] Example 2

[0044] Based on Example 1, such as Figure 1 and Figure 5 As shown, it also includes: anchor block assembly 3, which consists of anchor body 301, third ground nail 302, second rotating shaft 303, connecting seat 304, worm gear 305, rotating frame 306, worm 307, adjusting component 308 and ball bearing 309. There are four anchor bodies 301 in total. The four anchor bodies 301 are placed on the slope in pairs. Two anchor bodies 301 are located on the left side of the fixed frame 1, and the other two anchor bodies 301 are located on the right side of the fixed frame 1.

[0045] Each pier 301 is welded with a third ground nail 302, and all four third ground nails 302 are inserted into the soil; each pier 301 is rotatably connected with a second rotating shaft 303.

[0046] The second rotating shaft 303 is a cylindrical rod structure. Each second rotating shaft 303 is limited and slidably connected to a connecting seat 304 that is connected to the anchor cable. An anchor cable is connected between the two connecting seats 304 on the left and right sides, and the anchor cable is connected to the support block 101.

[0047] The support block 101 is a rectangular block structure. A groove is provided at the center of the top surface of the support block 101. The groove is a semi-cylindrical groove structure, and the anchor cable is engaged inside the groove.

[0048] Among them, a worm gear 305 is welded on the second rotating shaft 303; a rotating frame 306 is welded on the pier body 301, and a worm 307 is rotatably connected to the rotating frame 306, with the worm 307 meshing with the worm gear 305.

[0049] The second rotating shaft 303 is threaded, and an adjusting member 308 is threadedly connected to it. One end of the adjusting member 308 has a ring-shaped array of balls 309, which contact the connecting seat 304. When the anchor cable needs adjustment, the worm gear 307 is rotated directly. When the worm gear 307 is rotated, the worm wheel 305 and the second rotating shaft 303 rotate under its drive. The rotation of the second rotating shaft 303 drives the connecting seat 304 to rotate. When the connecting seat 304 rotates, the anchor cable can be tensioned. At this time, the tensioned anchor cable can press the fixing frame 1. When the worm 307 is damaged and cannot be adjusted, the adjusting part 308 can be rotated directly. When the adjusting part 308 rotates, the connecting seat 304 can be squeezed. The anchor cable can be tensioned by squeezing the connecting seat 304 backward. When rotating, the ball bearings 309 are arranged in a ring array at one end of the rear side of the adjusting part 308. The ball bearings 309 contact the connecting seat 304, making the adjustment convenient and quick.

The auxiliary component 4 consists of a threaded rod 401 and a pressing plate 402. The threaded rod 401 is threadedly connected to an inner connecting seat 304. A pressing plate 402 is rotatably connected to the lower end of the threaded rod 401. The pressing plate 402 is in contact with the anchor cable. When the adjusting component 308 is adjusted to the maximum adjustment range, the anchor cable can be tightened. At this time, the threaded rod 401 can be rotated. When the threaded rod 401 is rotated, the pressing plate 402 can be moved downward under the drive of the threaded rod 401. When the pressing plate 402 moves downward, the anchor cable can be tightened. At this time, the anchor cable can be tensioned.

[0052] The specific usage and function of this embodiment are as follows:

[0053] During fixing, the first ground nail 203 is directly fixed to the soil. After the first ground nail 203 is inserted into the soil, the second ground nail 204 is simultaneously inserted into the soil under the drive of the fixing frame 1. When the anchor cable needs to be adjusted, the worm gear 307 is rotated directly. When the worm gear 307 is rotated, the worm wheel 305 and the second rotating shaft 303 rotate under the drive of the worm gear 307. When the second rotating shaft 303 rotates, it can drive the connecting seat 304 to rotate. When the connecting seat 304 rotates, the anchor cable can be tensioned. At this time, the tensioned anchor cable can press the fixing frame 1. When the worm gear 307 is damaged and cannot be adjusted, the adjusting part 308 is rotated directly.
