Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, and in particular to a prestressed rock and soil anchor bolt support device. Background Technology

[0002] Anchor bolt support structures are made of metal, wood, polymer or other materials to form rods, which are driven into pre-drilled holes in the surface rock or the rock mass surrounding the cavern. The head, body and tail plate of the anchor bolt are used to bond it to the rock mass to achieve the purpose of support. In the construction process, in order to ensure the safety of the construction process and the building structure, it is usually necessary to reinforce the slope to stabilize the slope rock and soil and avoid disasters such as collapse.

[0003] Most existing anchor bolt support devices are fixed, and the support height and anchoring depth of the anchor bolt support devices are difficult to adjust, which cannot adapt to different engineering needs. When adjustment is required, it mainly relies on external tools such as hydraulic jacks, which makes the adjustment operation complicated and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a prestressed rock and soil anchor support device that can adjust the support height and anchoring depth to adapt to different support needs, with flexible adjustment and improved support stability.

[0005] To achieve the above objectives, a prestressed rock and soil anchor support device is provided, including a base, a support frame fixedly connected to the upper outer surface of the base, a stabilizing mechanism provided on the upper outer surface of the support frame, the stabilizing mechanism including a fixed column, the fixed column being fixedly connected to the upper outer surface of the support frame, a hollow rod being provided inside the fixed column, the lower end of the hollow rod slidingly penetrating through the lower outer surface of the fixed column and the top outer surface of the support frame, and being fixedly connected to a movable frame;

[0006] A reinforcing mechanism is provided on the upper outer surface of the base. The reinforcing mechanism includes a limiting cylinder. The upper end of the limiting cylinder is fixedly inserted through the bottom outer surface of the movable frame. A movable cylinder is provided inside the limiting cylinder.

[0007] According to the aforementioned prestressed rock and soil anchor support device, a knob is rotatably connected to the right outer surface of the fixed column, and a worm is fixedly connected to the left outer surface of the knob. The left end of the worm rotates through the right outer surface of the fixed column and is rotatably connected to the left inner surface of the fixed column. A worm wheel is meshed with the outer surface of the worm. Through the self-locking characteristics of the worm wheel and worm, the support structure can be prevented from retreating after being subjected to force, thereby improving stability.

[0008] According to the aforementioned prestressed rock and soil anchor support device, a lead screw is rotatably connected to the upper inner surface of the fixed column, a worm gear is fixedly connected to the upper outer surface of the lead screw, and a moving block is threadedly connected to the middle outer surface of the lead screw, the moving block being fixedly connected to the upper outer surface of the hollow rod.

[0009] According to the aforementioned prestressed rock and soil anchor support device, sliders are fixedly connected to the inner surfaces of both sides of the movable block, and a sliding groove is provided on the inner surface of the fixed column. The sliders are slidably connected to the sliding groove, and the sliders on both sides of the movable plate slide along the sliding groove on the inner wall of the fixed column to ensure a smooth lifting process, avoid deviation or jamming, and enhance the reliability of the overall structure.

[0010] According to the prestressed rock and soil anchor support device, a threaded rod is movably connected to the upper inner surface of the limiting cylinder, and a turntable is fixedly connected to the upper inner surface of the threaded rod.

[0011] According to the aforementioned prestressed rock and soil anchor support device, the movable cylinder is movably connected to the inner surface of the limiting cylinder, and the movable cylinder is internally threaded with a threaded rod.

The reinforcing blocks are rhomboid in shape. The rhomboid design of the reinforcing blocks can reduce insertion resistance and enhance the interlocking with the soil during pullback, thus preventing the anchor from loosening.

[0013] According to the prestressed rock and soil anchor support device, the movable frame is slidably connected to the inner surfaces of both sides of the support frame, and the anchor body is fixedly installed on the inner wall of the base.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, by rotating the knob, the worm gear is driven to rotate, which in turn drives the worm wheel that meshes with the worm gear to rotate, which in turn drives the lead screw that is fixedly connected to the inner surface of the worm wheel to rotate, which in turn drives the moving block that is threadedly connected to the lead screw to descend, which in turn drives the hollow rod and the moving frame to descend, so that the limiting cylinder descends into the hole wall. Then, the height of the support can be adjusted according to the actual engineering needs. At the same time, the worm gear has a self-locking characteristic, which can prevent the support structure from retreating after being stressed, improve stability, and achieve fixation of the anchor bolt body.

[0016] 2. Compared with the existing technology, by rotating the turntable, the threaded rod is driven to rotate, which in turn drives the movable cylinder to descend. Then, through the action of the fixed pile fixedly connected to the lower surface of the movable cylinder and the reinforcing block on the outer surface of the fixed pile, the friction between the limiting cylinder and the hole wall is increased, thereby further increasing the stability of the anchor bolt body.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a prestressed rock and soil anchor support device, which includes a base 1. An anchor body 11 is fixedly installed on the inner wall of the base 1. A support frame 2 is fixedly connected to the upper outer surface of the base 1. A stabilizing mechanism is provided on the upper outer surface of the support frame 2. The stabilizing mechanism includes a fixed column 3, which is fixedly connected to the upper outer surface of the support frame 2. A hollow rod 36 is provided inside the fixed column 3. The lower end of the hollow rod 36 slides through the lower outer surface of the fixed column 3 and the top outer surface of the support frame 2, and is fixedly connected to a movable frame 4. The movable frame 4 is slidably connected to the inner surfaces of both sides of the support frame 2.

[0027] A knob 31 is rotatably connected to the right outer surface of the fixed column 3. A worm gear 32 is fixedly connected to the left outer surface of the knob 31. The left end of the worm gear 32 rotatably passes through the right outer surface of the fixed column 3 and is rotatably connected to the left inner surface of the fixed column 3. A worm wheel 33 is meshed with the outer surface of the worm gear 32. A lead screw 34 is rotatably connected to the upper inner surface of the fixed column 3. A worm wheel 33 is fixedly connected to the upper outer surface of the lead screw 34. A moving block 35 is threadedly connected to the middle outer surface of the lead screw 34. Slider blocks 37 are fixedly connected to the inner surfaces of both sides of the moving block 35. A sliding groove 38 is opened on the inner surface of the fixed column 3. The slider 37 is slidably connected to the sliding groove 38. Through the action of the slider 37 and the sliding groove 38, the lifting process is ensured to be smooth, avoiding skew or jamming, and enhancing the reliability of the overall structure. The moving block 35 is fixedly connected to the upper outer surface of the hollow rod 36.

[0028] The above structure, by rotating the knob 31, drives the worm gear 32 and worm wheel 33 to rotate, which in turn drives the lead screw 34 to rotate, causing the moving block 35 and hollow rod 36 to move up and down, thereby achieving precise adjustment of the support height. At the same time, the worm wheel 33 and worm gear 32 have self-locking characteristics, which can prevent the support structure from retreating after being subjected to force, thereby improving the overall stability of the support structure.

[0029] A reinforcement mechanism is provided on the upper outer surface of the base 1. The reinforcement mechanism includes a limiting cylinder 5, which is fixedly inserted through the bottom outer surface of the movable frame 4. A threaded rod 7 is movably connected to the upper inner surface of the limiting cylinder 5. A turntable 6 is fixedly connected to the upper inner surface of the threaded rod 7. A movable cylinder 8 is provided inside the limiting cylinder 5 and is movably connected to the inner surface of the limiting cylinder 5. A threaded rod 7 is threadedly connected inside the movable cylinder 8. A fixing pile 9 is fixedly connected to the lower outer surface of the movable cylinder 8. Several reinforcement blocks 10 are fixedly connected to the outer surface of the fixing pile 9. The reinforcement blocks 10 are made of high-strength material and are rhomboid in shape. By rotating the threaded rod 7 through the turntable 6, the movable cylinder 8 is driven to move inside the limiting cylinder 5, which drives the fixing pile 9 and the reinforcement blocks 10 to penetrate deeper into the soil layer, thereby achieving adjustable anchoring depth and enhancing the anchoring effect. The rhomboid design of the reinforcement blocks 10 can reduce insertion resistance and enhance the interlocking with the soil during pullback, preventing the anchor rod from loosening.

[0030] Working principle: In use, this type of prestressed rock and soil anchor support device works by rotating the knob 31 after the anchor body 11 enters the borehole wall. This rotates the worm 32, which in turn rotates the worm wheel 33, which is meshed with the worm 32. This, in turn, rotates the screw 34, which is fixedly connected to the inner surface of the worm wheel 33. This, in turn, causes the moving block 35, which is threadedly connected to the screw 34, to descend. This further causes the hollow rod 36 and the moving frame 4 to descend, allowing the limiting cylinder 5 to descend into the borehole wall. This allows the support height to be adjusted according to the actual engineering needs. At the same time, the worm wheel 33 and worm 32 have self-locking characteristics, which can prevent the support structure from retreating after being stressed, improve stability, and achieve the fixation of the anchor body 11.

[0031] Then, by rotating the turntable 6, the threaded rod 7 is driven to rotate, thereby causing the movable cylinder 8 to descend. Through the action of the fixed pile 9 fixedly connected to the lower surface of the movable cylinder 8 and the reinforcing block 10 on the outer surface of the fixed pile 9, the friction between the limiting cylinder 5 and the hole wall is increased, thereby further increasing the stability of the anchor bolt body 11.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
