Description

Technical Field

[0001] This utility model relates to the field of pipeline installation equipment technology, specifically to an auxiliary device for pipeline installation in mine roadways. Background Technology

[0002] In the mining industry, the pipeline system within roadways is the lifeline ensuring critical functions such as ventilation, drainage, compressed air, and gas extraction. The stable, safe, and long-term reliable operation of these pipelines directly affects the safety and production efficiency of underground operations. Therefore, the installation devices used to fix, support, and install these pipelines are of paramount importance. Their core function is to ensure that the pipelines are accurately positioned and securely fixed to the roadway walls or support structures to withstand their own weight, internal medium pressure, and potential external loads, preventing displacement, vibration, or damage during service.

[0003] Currently, in the practice of pipe installation in mine roadways, a very common and direct method of fixing is to use expansion bolts to anchor the fixing components of the installation device to the roadway wall. Although this technology is simple to operate and low in cost, it has revealed obvious technical defects in practical applications.

[0004] Specifically, when drilling holes in walls and installing expansion bolts using an impact drill, the unevenness of the tunnel wall surface, the inhomogeneity of the internal materials, or the skill level of the operator can all cause minor, unintended displacement of the fasteners during final tightening. Although this displacement is small, it can accumulate into errors in long-distance, multi-support pipeline installation systems. Even a slight misalignment of a single fastener can cause a deviation from its intended connection point with the pipeline. This deviation is directly transmitted to subsequent installation stages, making it difficult to smoothly insert the pipeline into the fastener, or forcing installers to perform additional operations such as forced correction or hole enlargement of the pipeline or fastener. This not only increases the difficulty and time of on-site installation and reduces construction efficiency, but also may lead to initial stress at the connection point due to forced assembly, or prevent the anchoring force between the expansion bolt and the wall from reaching the design value. This can create potential hazards such as loosening, detachment, or even safety accidents in the long-term operation of the pipeline system.

[0005] Therefore, there is an urgent need to develop a pipeline installation auxiliary device that can effectively compensate for installation deviations and achieve rapid and accurate alignment. Utility Model Content

[0006] The present invention aims to provide an auxiliary device for pipeline installation in mine roadways, so as to improve the adaptability of the installation auxiliary device, reduce the existing pipeline installation error, improve the accuracy and stability of pipeline positioning, and improve installation efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides an auxiliary device for pipe installation in mine roadways. By flexibly adjusting the clamping angle and position of the device, a self-centering clamping structure is formed, ensuring the center stability of the pipe to be installed, reducing positioning deviation, improving installation accuracy and effectiveness, effectively reducing installation difficulty, and improving installation efficiency. Specifically, the auxiliary device for pipe installation in mine roadways includes an installation plate mounted on the roadway wall. A first adjusting rod is provided on one side of the installation plate, and a first connecting plate is provided at one end of the first adjusting rod. A second connecting plate is movably mounted on the upper part of the first connecting plate, and a second adjusting rod is provided on the upper part of the second connecting plate. A U-shaped frame is provided on the upper part of the second adjusting rod, and a first clamping block and a second clamping block for clamping the pipe to be installed are movably mounted in the middle of the U-shaped frame. The first clamping block and the second clamping block are slidably arranged relative to each other.

[0008] The principle and advantages of this scheme are: This design creates a self-centering mechanism by driving the first and second clamping blocks to move synchronously radially within the U-shaped frame. This automatically compensates for installation errors, ensuring that the clamping center of the clamping blocks is always aligned with the theoretical axis of the pipeline. The cooperation of the adjusting shaft and the rotating shaft enables flexible multi-angle adjustment of the clamping mechanism in space, and rigid locking via through holes and bolts ensures stable final posture. Simultaneously, the spring and inner clamping plate together form a flexible force-applying unit, converting concentrated locking force into uniformly distributed surface pressure. The rubber layer at the end provides necessary friction and anti-slip protection, improving clamping reliability, preventing pipeline slippage, and also providing vibration reduction and noise reduction protection.

[0009] This solution eliminates pipeline axis misalignment caused by processing or assembly errors at its source, ensuring precise alignment during pipeline installation and laying the foundation for stable system operation. Simultaneously, the rigid bolt locking mechanism, adjustable at multiple angles, provides strong fixing force, which, combined with the robust U-shaped frame foundation, ensures long-term pipeline stability under complex operating conditions. Furthermore, it supports multi-dimensional angle adjustment, flexibly adapting to different installation spaces and pipeline routing requirements, greatly enhancing the versatility of the device.

[0010] Furthermore, the first clamping block and the second clamping block are respectively provided with arc-shaped grooves that match the shape of the surface of the pipe to be installed on their opposite sides; multiple sets of springs are arranged around the inner side of the arc-shaped grooves; an inner clamping plate with the same shape as the arc-shaped surface is provided on the outer side of the springs, and the inner side of the inner clamping plate abuts against the outer surface of the pipe to be installed.

[0011] Furthermore, adjusting screws are respectively provided on the outer sides of the first clamping block and the second clamping block, and the adjusting screws are rotatably mounted on the two side walls of the U-shaped frame.

[0012] Furthermore, an adjusting seat is provided at the end of the first connecting plate, and a plurality of positioning through holes are provided circumferentially on the side wall of the adjusting seat; an adjusting shaft is provided at the lower end of the second connecting plate, and the adjusting shaft is located inside the adjusting seat; a plurality of limiting holes that cooperate with the positioning through holes are provided circumferentially on the side wall of the adjusting shaft.

[0013] Furthermore, a rotating shaft is fixedly connected to the center of the adjusting shaft, and the adjusting shaft is movably disposed within the adjusting seat via the rotating shaft, with the limiting hole surrounding the rotating shaft.

[0014] Furthermore, the first adjusting rod and the second adjusting rod have the same structure, both including a sleeve, a rod, and a contact screw; the rod is located inside the sleeve and is slidably connected; the contact screw is located at one end of the sleeve, and its end passes through the sleeve and abuts against the outer wall of the built-in rod.

[0015] Furthermore, a rubber layer is provided on the inner side of the inner clamping plate.

[0016] Furthermore, the spring comprises 2 to 5 groups, each group being arranged side by side on the arc-shaped groove; each group comprises 1 to 3 spring members arranged side by side.

[0017] Furthermore, a bolt for fixing the positioning through hole and the limiting hole is provided on one of the positioning through holes.

Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method: Example 1 This embodiment is basically as shown in the appendix. Figure 1 The diagram illustrates an auxiliary device for pipeline installation in mine roadways. This device allows for flexible, multi-angle adjustment, enhancing its adaptability, reducing deviations between the clamping blocks and the pipeline axis caused by installation errors, ensuring precise alignment and stability during pipeline installation, lowering installation difficulty, and improving overall efficiency. It includes a mounting plate 1 for installation on the roadway wall. In this embodiment, the mounting plate 1 is a rectangular structure, serving as the foundation of the entire device. The mounting plate 1 secures the entire device to the roadway wall. Expansion bolts are used to connect the mounting plate 1 to the wall through the four corner mounting holes.

[0022] A corrosion-resistant coating is also provided on the outer surface of the mounting plate 1. In this embodiment, the corrosion-resistant coating is used to protect the mounting plate 1 from the erosion of moisture, corrosive gases or chemicals in the mine roadway, effectively extending the service life of the mounting plate 1.

[0023] A first adjusting rod 2 is fixedly connected to one side of the mounting plate 1. A first connecting plate 3 is provided at one end of the first adjusting rod 2. A second connecting plate 4 is movably provided on the upper part of the first connecting plate 3. A second adjusting rod 5 is fixedly installed on the upper part of the second connecting plate 4. A U-shaped frame 6 is installed on the upper part of the second adjusting rod 5. A first clamping block 7 and a second clamping block 8 for clamping the pipe to be installed are movably provided in the middle of the U-shaped frame 6. The first clamping block 7 and the second clamping block 8 are slidably arranged relative to each other.

[0024] Combined with appendix Figure 2 As shown in this embodiment, the first clamping block 7 and the second clamping block 8 are two sliding blocks with a semi-circular arc structure on one side. On the opposite side, i.e. the inner side, of the first clamping block 7 and the second clamping block 8, arc grooves matching the surface shape of the pipe to be installed are respectively provided. By adjusting the relative position of the arc grooves on both sides, the pipe to be installed is clamped to adapt to pipes of different diameters, thereby improving adaptability and versatility.

[0025] Multiple sets of springs 15 are arranged around the inner side of the arc-shaped groove. On the outer side of the springs 15, that is, on the side of the springs 15 away from the arc-shaped groove, there is an inner clamping plate 16 with the same shape as the arc-shaped surface. The inner side of the inner clamping plate 16 abuts against the outer surface of the pipe to be installed. At the same time, a rubber layer is also provided on the inner side of the inner clamping plate 16.

[0026] In this embodiment, the springs 15 include 2 to 5 groups, each group being fixedly arranged side-by-side on the arc-shaped groove; each group includes 1 to 3 spring members arranged side-by-side. Specifically, during installation, the number of springs 15 and the number of groups can be flexibly adjusted according to the width of the arc-shaped groove, such as setting 3 groups of springs, with 3 springs in each group. The springs 15 provide elastic support and buffer and absorb some external forces during clamping, reducing the rigid impact on the pipe. At the same time, the inner clamping plate 16 is in direct contact with the pipe, and the rubber layer increases the friction between the contact surface and the pipe, preventing the pipe from sliding during clamping, thereby ensuring the stability of the pipe and reducing errors.

[0027] Adjusting screws 9 are fixedly installed on the outer sides of the first clamping block 7 and the second clamping block 8, respectively. The adjusting screws 9 are rotatably mounted on the two side walls of the U-shaped frame 6. In this embodiment, adjusting screws 9 are installed on the sides of the first clamping block 7 and the second clamping block 8 that are far apart from each other, for driving the two clamping blocks to slide relative to each other. The distal thread of the adjusting screw 9 passes through the side wall of the U-shaped frame 6 and can rotate within the side wall of the U-shaped frame 6, providing a frame structure for installing and adjusting the first clamping block 7 and the second clamping block 8. Rotation of the adjusting screws 9 causes the clamping blocks to slide back and forth, allowing them to slide on the bottom side of the U-shaped frame 6. Adjusting the adjusting screws 9 on both sides causes the first clamping block 7 and the second clamping block 8 to move closer or further apart, thereby controlling the clamping of pipes of various diameters to be installed, ensuring the pipes are firmly clamped, and achieving the clamping and fixing of the pipes. The simple structure allows for flexible adjustment of clamping force and clamping diameter, making installation and operation easier, improving overall efficiency, and ensuring operational safety.

[0028] Combined with appendix Figure 3 As shown, an adjusting seat 12 is fixedly provided at the end of the first connecting plate 3, and the front end of the adjusting seat 12 has an arc-shaped structure. Multiple positioning through holes 13 are circumferentially arranged on the two side walls of the adjusting seat 12. In this embodiment, the number of positioning through holes 13 can be set according to the required rotation angle. If a smaller adjustment angle is required, more closely spaced positioning through holes 13 can be provided, with an included angle of 5~10° between each positioning through hole 13; if a larger adjustment angle is required, more sparsely spaced positioning through holes 13 can be provided, with an included angle of 20~60° between each positioning through hole 13. The required number of positioning through holes 13 can be flexibly set according to the adjustment angle requirements to ensure the effectiveness and adaptability of the angle adjustment, and also reduce the complexity of the device design.

[0029] As attached Figure 2As shown, a circular adjusting shaft 10 is fixedly connected to the lower end of the second connecting plate 4 by screws. The adjusting shaft 10 is movably installed within the adjusting seat 12, allowing the two to rotate relative to each other. By removing the screws, the second connecting plate 4 and the adjusting shaft 10 can be separated for easy transportation. In this embodiment, multiple limiting holes 17 that mate with the positioning through holes 13 are also provided circumferentially on both side walls of the adjusting shaft 10. In this embodiment, the number of limiting holes 17 is arranged in the same way as the positioning through holes 13, and will not be described again here. Specifically, a rotating shaft 11 is fixedly connected to the center of the adjusting shaft 10, and the adjusting shaft 10 is movably installed within the adjusting seat 12 via the rotating shaft 11, allowing the adjusting shaft 10 to rotate within the adjusting seat 12. The limiting holes 17 are arranged around the outer periphery of the rotating shaft 11. A bolt 14 is also provided on one of the positioning through holes 13 for fixing the positioning through hole 13 and the limiting hole 17 to rotate relative to each other.

[0030] The adjustment shaft 10 and the adjustment seat 12 cooperate to provide a function of mutual rotational adjustment. The rotating shaft 11 is rotatably connected to the adjustment seat 12, allowing the adjustment seat 12 to rotate around the rotating shaft 11, thereby realizing angle adjustment. The adjustment seat 12 provides a rotatable platform, allowing the U-shaped frame 6 to adjust the angle as needed to adapt to different installation scenarios. The positioning through hole 13 and the limiting hole 17 are used to fix the relative position of the adjustment seat 12 and the adjustment shaft 10. By selecting different hole alignments and fixing them with bolts 14, different angles can be adjusted and fixed.

[0031] In this embodiment, the first adjusting rod 2 and the second adjusting rod 5 have the same structure, both including a sleeve 201, a sleeve rod 202, and a connecting screw 203. For ease of understanding, the following description uses the first adjusting rod 2 as an example, in conjunction with the attached... Figure 4 As shown, the sleeve rod 202 is disposed within the sleeve 201 and slidably connected. The sleeve 201 is the main body of the first adjusting rod 2, providing a sliding channel that allows the sleeve rod 202 to move freely within it, thereby achieving length adjustment. The sleeve rod 202 adjusts the length of the first adjusting rod 2 by sliding within the sleeve 201 to adapt to different installation distance requirements. The abutment screw 203 is disposed at one end of the sleeve 201 through a threaded hole, and its end passes through the sleeve 201 and abuts against the outer wall of the built-in sleeve rod 202, thereby locking the position of the sleeve rod 202 and ensuring that the first adjusting rod 2 remains stable at the set length.

[0032] The implementation process is as follows: As attached Figures 1 to 4 As shown, when pipe installation is required, the mounting plate 1 is first fixed to the wall at the designated position using expansion bolts. Then, according to the position and direction of the pipe to be installed, the angle of the adjusting shaft 10 is rotated, and it is fixed to the adjusting seat 12 with bolts 14 to ensure the angular position and stability of the entire upper part of the device.

[0033] Then, by rotating the two sets of adjusting screws 9 respectively, the first clamping block 7 and the second clamping block 8 can be driven to achieve synchronous radial displacement within the U-shaped frame 6, forming a self-centering clamping structure to position and clamp the pipe to be installed, thereby reducing the deviation from the pipe axis caused by installation errors and thus completing the rapid installation of the pipe.

[0034] In this embodiment, by rotating two sets of independent adjusting screws, the first clamping block 7 and the second clamping block 8 are precisely driven to move synchronously radially within the U-shaped frame 6, thus forming a self-centering structure that automatically eliminates installation errors and ensures that the clamping center is always precisely aligned with the pipeline axis. Based on this, the clamping angle is flexibly and infinitely adjusted via the adjusting shaft 10 and the adjusting seat 12, and the final position is rigidly fixed using through holes and bolts, ensuring overall stability. Finally, the spring 15 and the inner clamping plate 16 together form a buffer system, converting the concentrated locking force into a uniformly distributed clamping force. Combined with the anti-slip and friction-enhancing effects of the rubber pad, this ultimately achieves flexible and reliable grip on the pipeline, improving the adaptability of pipeline installation.
