Description

Technical Field

[0001] This utility model relates to the field of support and repair technology, and in particular to a fixing structure for support and repair. Background Technology

[0002] In the field of underground engineering, such as mine tunnel excavation, as ore is mined, the stress state of the rocks around the tunnel changes, and the original rock mass balance is disrupted. In order to prevent the surrounding rock of the tunnel from deforming and collapsing, an effective support, repair and fixation structure is needed. For example, in coal mine tunnels, due to the mining of coal seams, the rocks on the roof, floor and sides of the tunnel will become loose and cracks will expand. According to statistics, about 70% of tunnel instability accidents are caused by improper support.

[0003] Existing technologies, such as the utility model patent with publication number CN212405165U, disclose a repair structure for foundation pit support piles. This patent employs a ring hoop assembly around the crack on the pile body. The ring hoop assembly includes a repair panel, which can be detachably configured as a first half-plate and a second half-plate. One end of the first half-plate and the second half-plate are respectively fixed to the inner wall of the foundation pit or an adjacent pile body. A locking assembly for connecting the first half-plate and the second half-plate is provided on the other side of the first half-plate and the second half-plate. The locking assembly is located on the outer side of the repair panel. This solves the problem that in reality, cracks in the pile body are not necessarily located at the point where the pile body and the foundation pit collapse. When the crack occurs at the height where the pile body is in contact with the foundation pit, the repair frame and repair installation ring cannot be fitted onto the pile body because one side of the pile body is fixed to the side wall of the foundation pit.

[0004] During the repair process, the aforementioned fixing structure can only fix the position of one support pile at a time. When multiple support piles need to be repaired and fixed, this method of installation one by one makes the construction process cumbersome. Construction workers need to frequently move tools and equipment between different support piles, and each installation requires repositioning and calibration. It cannot be batch operated like a structure that fixes multiple support piles at the same time, which reduces the overall efficiency of construction. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing technologies can only fix the position of a single support pile. When multiple support piles need to be repaired and fixed, this method of installing them one by one makes the construction process cumbersome. Construction workers need to frequently move tools and equipment between different support piles, and each installation requires repositioning and calibration. It cannot be batch operated like a structure that fixes multiple support piles at the same time, thus reducing the overall efficiency of construction. Therefore, this utility model proposes a fixing structure for support repair.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a fixed structure for support and repair, comprising a pile body movably disposed in a groove of a foundation pit, a pile core fixedly connected to the center of the pile body, a fixing assembly fixedly disposed on the upper surface of the foundation pit, the fixing assembly including a mounting frame, the mounting frame being fixedly connected to the upper surface of the foundation pit, a guide groove being provided on the side surface of the mounting frame, a limit hole being provided on the side of the mounting frame near the guide groove, a fixing plate being in contact with the side surface of the mounting frame, and an installation...

[0007] Preferably, the mounting bracket is arranged in an "L" shape, and there are two mounting brackets. The two mounting brackets are symmetrically arranged at the center of the foundation pit, which facilitates the support of the fixed plate.

[0008] Preferably, the limiting hole is rectangular and there are multiple limiting holes. The multiple limiting holes are horizontally distributed on the mounting bracket. The limiting holes facilitate locking the position of the limiting block to ensure the stability of the limiting block in the locked state.

[0009] Preferably, the fixing plate is arc-shaped on the side closest to the pile body, the fixing plate is in contact with the outer arc surface of the pile body, and the fixing plate is in contact with the surface of the foundation pit. The fixing plate facilitates the fixation of the pile body's position to prevent the pile body from tilting and collapsing during support.

[0010] Preferably, the slide groove is located on one side near the connecting block, and there are two slide grooves. The two slide grooves are located at the center of the slide plate and are arranged symmetrically from top to bottom. The slide grooves can guide the direction of movement of the slide plate to ensure that the slide plate moves in a horizontal direction.

[0011] Preferably, the slider is slidably connected to the inner wall of the groove, the slider is rectangular, the slider is in contact with the side surface of the limiting hole, and there are two sliders. The two sliders are located in the middle of the fixed plate and are symmetrically arranged from left to right. Through the cooperation of the slider and the rack, the position of the fixed plate can be supported, and the position of the fixed plate can be avoided from shifting when the fixed plate moves.

[0012] Preferably, the toothed block engages with the toothed groove of the rack, the toothed block slides on the side surface of the limiting hole, the toothed block contacts the inner wall of the mounting groove, and there are two toothed blocks. The two toothed blocks are symmetrically arranged in the middle of the fixing plate.

[0013] Preferably, the limiting block is inserted into the inner wall of the limiting hole, the limiting block is in contact with the inner wall of the mounting groove, and the limiting block is in contact with the inner wall of the guide groove. The limiting block is arranged in an "L" shape, and there are two limiting blocks. The two limiting blocks are located in the middle of the fixing plate and are arranged symmetrically from left to right. The position of the fixing plate can be fixed by the limiting blocks to ensure the fixation of the fixing plate to the pile body.

[0014] Preferably, the shaft is inserted into the limiting spring and contacts the inner wall of the linkage groove. There are two shafts, which are symmetrically arranged at the center of the connecting block. The limiting spring facilitates the application of a reset spring force to the tooth block.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this utility model, by setting a fixing component, when the position of the pile needs to be repaired and fixed, the worker holds the connecting blocks on both sides with both hands and pulls the connecting blocks outward. The connecting blocks pull the toothed blocks to move towards the sliding plate, and the movement compresses the limiting spring. The limiting spring deforms under the compression, and then drives the toothed blocks to move towards the sliding plate. When the toothed blocks move away from the rack, the worker continues to pull the connecting blocks, and at the same time, the connecting blocks on both sides move towards the middle. As the connecting blocks move, the sliding plate, guided by the sliding groove, guides the toothed blocks and drives the limiting blocks to move along the mounting groove towards the middle of the fixing plate, so that the limiting blocks move away from the limiting holes, and then the position of the fixing plate is no longer restricted.

[0017] Then, according to the position of the pile, the fixing plate can be pushed. As the fixing plate is pushed, the slider moves towards the pile under the guidance of the guide groove until the fixing block is completely in contact with the surface of the main body. Then, the hands holding the connecting block can be released, and the limit spring will return to its original position, driving the toothed block to move along the limit block towards the rack. The moving block abuts against the tooth groove of the rack. Then, under the action of the rack's chamfer, the toothed block drives the limit block to move towards the limit hole until it is completely inserted into the limit hole. Then, the position of the fixing plate is fixed. The fixing plate can fix the position of the support. By setting the fixing component, multiple supports can be clamped at the same time. Compared with fixing a single pile one by one, the number of installations can be greatly reduced, thereby further saving construction time. Attached Figure Description

[0033] The effect achieved by the above components is that the position of the pile 2 can be easily fixed by the fixing plate 44 to prevent the pile 2 from tilting and collapsing during support.

[0034] Specifically, the slide groove 46 is located on one side near the connecting block 415. There are two slide grooves 46, which are located at the center of the slide plate 410 and are arranged symmetrically from top to bottom.

[0035] The effect achieved by the above components is that the sliding groove 46 can guide the direction of movement of the sliding plate 410 to ensure that the sliding plate 410 moves in a horizontal direction.

[0036] Specifically, the slider 49 is slidably connected to the inner wall of the groove 46. The slider 49 is rectangular and contacts the side surface of the limiting hole 43. There are two sliders 49, which are symmetrically arranged in the middle of the fixing plate 44.

[0037] The effect achieved by the above components is that the position of the fixed plate 44 can be supported by the cooperation of the slider 49 and the rack 48, so as to prevent the fixed plate 44 from shifting its position when it moves.

[0038] Specifically, the toothed block 412 meshes with the tooth groove of the rack 48, the toothed block 412 slides with the side surface of the limiting hole 43, the toothed block 412 contacts the inner wall of the mounting groove 45, and there are two toothed blocks 412, which are symmetrically arranged in the middle of the fixing plate 44.

[0040] Specifically, the limiting block 413 is inserted into the inner wall of the limiting hole 43, the limiting block 413 is in contact with the inner wall of the mounting groove 45, and the limiting block 413 is in contact with the inner wall of the guide groove 42. The limiting block 413 is arranged in an "L" shape, and there are two limiting blocks 413. The two limiting blocks 413 are located in the middle of the fixing plate 44 and are arranged symmetrically from left to right.

[0041] The effect achieved by the above components is that the position of the fixing plate 44 can be fixed by the limiting block 413 to ensure the fixation of the fixing plate 44 to the pile body 2.

[0042] Specifically, the shaft 414 is inserted into the limiting spring 411, and the shaft 414 is in contact with the inner wall of the linkage groove 47. There are two shafts 414, which are symmetrically arranged at the center of the connecting block 415.

[0043] The effect achieved by the above components is that the limiting spring 411 facilitates the application of a reset spring force to the tooth block 412.

[0044] Working principle: When the position of pile 2 needs to be repaired and fixed, the worker holds the connecting blocks 415 on both sides with both hands and pulls the connecting blocks 415 outward. The connecting blocks 415 pull the toothed blocks 412 to move towards the sliding plate 410, which compresses the limiting spring 411. The limiting spring 411 deforms under the compression, which in turn drives the toothed blocks 412 to move towards the sliding plate 410. When the toothed blocks 412 move away from the rack 48, the worker continues to pull the connecting blocks 415, which in turn drives the connecting blocks 415 on both sides to move towards the middle. As the connecting blocks 415 move, the sliding plate 410, guided by the sliding groove 46, guides the toothed blocks 412 and drives the limiting blocks 413 to move along the mounting groove 45 towards the middle of the fixing plate 44. This causes the limiting blocks 413 to move away from the limiting holes 43, and the position of the fixing plate 44 is no longer restricted.

[0045] Then, according to the position of the pile 2, the fixing plate 44 can be pushed. While the fixing plate 44 is pushed, the slider 49 moves towards the pile 2 under the guidance of the guide groove 42. It moves until the fixing block is completely in contact with the surface of the main body. Then, the hands holding the connecting block 415 can be released. Then, the limiting spring 411 rebounds and resets, and drives the toothed block 412 to move along the limiting block 413 towards the rack 48. It moves and abuts against the tooth groove of the rack 48. Then, under the action of the chamfer of the rack 48, the toothed block 412 drives the limiting block 413 to move towards the limiting hole 43. It moves until it is completely inserted into the limiting hole 43, and then the position of the fixing plate 44 is fixed. The fixing plate 44 can fix the position of the support. By setting the fixing component 4, multiple supports can be clamped at the same time. Compared with fixing a single pile 2 one by one, the number of installations can be greatly reduced, thereby further saving construction time.
