Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing technology, and in particular to a pipeline fixing device. Background Technology

[0002] In the underground working environment of coal mines, pipelines for ventilation, drainage, and power supply systems need to be stably laid along the roadway walls, and their reliability directly affects mine production safety. Traditional fixing methods often use welded supports or wire binding. However, welded supports require on-site welding of metal supports to roadway wall anchors, which is not only inefficient—limited by the narrow underground space and power supply conditions, welding operations require specialized equipment and are extremely difficult to perform—but also highly dependent on the worker's skill level, with welds susceptible to corrosion from humid environments or external impacts, leading to cracks. Furthermore, the fixed size of the supports makes it difficult to accommodate multi-specification pipelines or subsequent pipeline layout adjustments, resulting in insufficient system scalability. On the other hand, while wire binding does not require complex equipment, it suffers from poor stability and significant safety hazards. Wires are prone to loosening and slipping due to roadway vibration or the weight of the pipeline itself, causing pipeline displacement; sharp wire ends may scratch the pipeline's anti-corrosion layer or workers, leading to secondary accidents. Additionally, wire is a single-use material and cannot be reused after disassembly, resulting in resource waste and increased long-term operating costs. Utility Model Content

[0003] The purpose of this utility model is to provide a pipeline fixing device that can be anchored to the sidewall of the tunnel, has high stability, and has an anti-detachment structure to prevent the pipeline from loosening and falling off; moreover, it is easy to install and disassemble, and convenient for secondary use.

[0004] To achieve the above objectives, this utility model provides a pipeline fixing device, including an anchor rod that can be anchored into the roadway wall and a hanging device fixed to the anchor rod; the hanging device includes a base plate, a hook fixed to the base plate, and a retaining ring to prevent the pipeline from detaching; the top of the base plate is fixed to the anchor rod; the hook portion of the hook is bent upward to form an upward-opening hook structure; the retaining ring is placed on the outside of the hook and its top and bottom are respectively fixed to the base plate; the retaining ring and the base plate form a pipeline channel; the hook is set inside the pipeline channel.

[0005] With the above structure, the stability of the device is ensured by anchoring the anchor bolts into the roadway side; by first supporting the pipe on the hook and then fixing the retaining ring to the base plate, the hook and retaining ring form an anti-detachment structure, thus preventing the pipe from loosening and falling off; in addition, by fixing the base plate to the anchor bolts, it is convenient to install and disassemble, and the device will not be damaged when disassembled, so it can be reused.

[0006] Preferably, multiple hooks are vertically arranged, with a certain distance between adjacent hooks to avoid interference; multiple hooks are enclosed within the same retaining ring. This structure allows for the simultaneous fixing of multiple pipes.

[0007] Preferably, an anchor bolt is screwed with a mounting nut, and the mounting nut has a mounting plate extending circumferentially therefrom. The base plate is hinged to the mounting plate by locking bolts.

[0008] Preferably, the mounting nut includes a hexagonal nut screwed onto the anchor bolt and a collar fixed to one side of the hexagonal nut; a mounting plate is disposed on the collar. This structure extends the length of the mounting nut, facilitating installation.

[0009] Preferably, a tightening bolt is installed at the bottom of the base plate, penetrating the base plate and abutting against the side wall of the tunnel. This structure reduces the pressure on the mounting nuts, adjusts the gap between the bottom of the base plate and the side wall of the tunnel, and improves the stability of the device.

[0010] Preferably, a handwheel is provided on the side of the tightening bolt located above the base plate. This design facilitates the tightening operation of the tightening bolt.

[0011] Preferably, after the retaining ring is installed, it abuts against the outer wall of the pipe, pressing the pipe firmly against the side of the hook closest to the base plate. This structural design improves the retaining ring's anti-detachment effect.

[0012] Preferably, the top of the retaining ring is hinged to the top of the base plate, and its bottom is detachably fixed to the bottom of the base plate. This structure facilitates the opening and closing of the retaining ring.

[0013] Preferably, two retaining rings are provided, located on both sides of the hook. This structure creates symmetrical clamping by the two retaining rings, improving resistance to lateral displacement.

[0014] Preferably, the tops of the two retaining rings are hinged to both sides of the base plate, and their bottoms are fixedly connected by a connecting rod; a positioning plate is provided on the connecting rod; the bottom of the base plate is provided with a positioning groove for the positioning plate to be inserted, and the positioning groove and the positioning plate are fixedly connected by a pin.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] The orientations mentioned in this specification are based on the orientation of the pipeline fixing device of this utility model when it is working normally, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0026] Example 1:

[0027] like Figure 1 As shown, a pipeline fixing device includes an anchor rod 1 that can be anchored into the roadway wall and a hanging device 2 fixed to the anchor rod 1. The anchor rod 1 has a threaded structure and is anchored into the roadway wall, with the exposed top section used to fix the hanging device 2.

[0028] The hanging device 2 includes a base plate 21, a hook 22 fixed on the base plate 21, and a retaining ring 23 that prevents the pipe 3 from being hooked off.

[0029] The top of the base plate 21 is fixed to the anchor bolt 1. In this embodiment, one fixing method is as follows: an upwardly extending fixing plate 211 is fixedly installed on the base plate 21. The fixing plate 211 has a through hole, which is fitted onto the anchor bolt 1 at one end located on the outer side of the roadway. Then, by installing a tightening nut on the anchor bolt 1, the tightening nut clamps the fixing plate 211 between the tightening nut and the roadway side, thereby fixing the base plate 21 to the anchor bolt 1.

[0030] The hook portion of hook 22 bends upward to form an upward-opening hook structure for supporting pipe 3. Furthermore, in order to fix multiple pipes at the same time, multiple hooks 22 are vertically arranged. In this embodiment, three hooks 22 are provided, which can fix three pipes 3 at the same time. In actual applications, two or other numbers can be set as needed. This embodiment does not limit this.

[0031] A retaining ring 23 is fitted over the outside of the hook 22, and its top and bottom are fixed to the base plate 21 respectively; the retaining ring 23 and the base plate 21 form a pipe channel; the hook 22 is set inside the pipe channel. The retaining ring 23 can prevent the pipe from detaching laterally, thereby achieving the function of limiting the pipe 3. When the pipe 3 passes through the pipe channel, the retaining ring 23 and the hook 22 form a limit, so that the pipe 3 is always confined within the bend of the hook 22 and does not detach.

[0032] In this embodiment, three hooks 22 are provided, and the hooks 22 that are adjacent to each other do not interfere with each other. In order to make reasonable use of space, multiple hooks 22 are enclosed within the same retaining ring 23.

[0033] Preferably, to enhance the limiting function of the retaining ring 23, after installation, the retaining ring 23 abuts against the outer wall of the pipe 3, pressing the pipe 3 tightly against the side of the hook 22 near the base plate 21. This creates a clamping force, preventing lateral swaying. Of course, in practical applications, the retaining ring 23 can also be installed without abutting against the outer wall of the pipe 3, but its distance from the outer wall should be reasonably controlled to avoid rendering the limiting function of the retaining ring 23 ineffective.

[0034] Preferably, the top and bottom of the retaining ring 23 are fixed to the base plate 21 respectively. It can be fixed by plugging or by bolts. In this embodiment, in order to facilitate the opening and closing of the retaining ring 23, a hinged fixing method is adopted. Specifically, the top of the retaining ring 23 is hinged to the top of the base plate 21, and its bottom is detachably fixed to the bottom of the base plate 21.

[0035] To improve the limiting effect, two retaining rings 23 are provided, located on both sides of the hook 22. The two retaining rings 23 form a symmetrical clamping, improving the resistance to lateral displacement. The tops of the two retaining rings 23 are hinged to both sides of the base plate 21, and their bottoms are fixedly connected by a connecting rod 231. The two retaining rings 23 are fixedly connected by the connecting rod 231, enabling the synchronous opening of the two retaining rings 23, which greatly improves the convenience of operation. A positioning plate is provided on the connecting rod 231; the bottom of the base plate 21 is provided with a positioning groove for the positioning plate to be inserted, and the positioning groove and the positioning plate are fixedly connected by a pin.

[0036] When disassembling pipe 3, the retaining ring 23 needs to be opened first. The opening method is as follows: pull the pin out from between the positioning groove and the positioning plate to eliminate the connection between the two, then rotate the retaining ring 23 upwards. The retaining ring 23 flips over, thus opening the retaining ring 23. Then, pipe 3 can be taken out from the corresponding hook 22.

[0037] Example 2:

[0038] This embodiment is a further improvement on Embodiment 1. Because the angle of the tunnel wall is not always consistent, the angle of anchor rod 1 is not always vertical when it is driven into the tunnel wall. When anchor rod 1 needs to be driven into the tunnel wall at an angle, this embodiment is improved in order to facilitate the adjustment of the installation angle of the hanging device 2.

[0039] like Figures 2-6 As shown, an anchor bolt 1 is screwed with a mounting nut 11, and a mounting plate 12 extending circumferentially from the mounting nut 11 is provided on it. The base plate 21 is hinged to the mounting plate 12 by a locking bolt 24. Specifically, the mounting nut 11 includes a hexagonal nut 111 screwed onto the anchor bolt 1 and a collar 112 fixed to one side of the hexagonal nut 111; the mounting plate 12 is disposed on the collar 112. With this structure, the mounting nut 11 is first screwed onto the anchor bolt 1, and then the base plate 21 is hinged to the mounting plate 12 by the locking bolt 24. After the angle adjustment is completed, the locking bolt 24 is tightened to achieve a fixed connection of the base plate 21.

[0040] Furthermore, to accommodate adjustments to different pitch angles and to reduce the pressure on the locking bolt 24 while improving the stability of the device, a tightening bolt 25 is installed at the bottom of the base plate 21 in this embodiment. The tightening bolt 25 penetrates the base plate 21 and abuts against the side wall of the tunnel. A handwheel is provided on the side of the tightening bolt 25 located above the base plate 21 for easy rotation.

[0041] Working principle:

[0042] Anchoring stage: Anchor bolt 1 is inserted into the pre-set hole in the roadway side. First, the mounting nut 11 is screwed onto anchor bolt 1. Then, the base plate 21 is hinged to the mounting plate 12 using locking bolts 24. After the angle adjustment is completed, the locking bolts 24 are tightened to achieve a fixed connection of the base plate 21. Rotate the tightening bolts 25 to eliminate the gap between the base plate 21 and the roadway side.

[0043] Hanging stage: Open the retaining ring 23, put the pipe 3 into the hook 22, close the retaining ring 23 and fix the bottom; when multiple pipes run in parallel, the hooks 22 can be arranged in layers within the same retaining ring 23.

[0044] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
