Description

A municipal pipeline transportation device Technical Field

[0001] This application relates to the field of municipal engineering equipment, and in particular to a municipal pipeline transportation device. Background Technology

[0002] Municipal pipeline installation, a core component of urban infrastructure construction, aims to meet the transmission needs of systems such as water supply, drainage, gas, and electricity. Traditional construction processes include pit excavation, pipeline laying, and backfilling. After excavation, the pipeline must be lowered from the ground into the pit, and then moved and repositioned within the pit. However, in densely populated urban areas, such as narrow streets, old urban areas, or sections adjacent to buildings, the space around the pit is often limited, typically less than 2 meters wide. This prevents large hoisting equipment from accessing the work area, forcing construction workers to manually move the pipeline within the pit to its installation location. This method not only significantly extends the construction period but also greatly increases the labor intensity for workers. Therefore, a specialized transportation tool is urgently needed to overcome these technical bottlenecks. Summary of the Invention

[0003] In view of the shortcomings of the prior art, this application provides a municipal pipeline transportation device, which aims to solve the above-mentioned problems.

[0004] A municipal pipeline transportation device includes a base for placing a pipeline. Both sides of the base are detachably connected to limiting parts. At least two mounting blocks are installed on the lower end face of each limiting part. Each mounting block is equipped with a caster wheel. The base has a fixing groove for placing the pipeline. Both ends of the upper end face of the base are provided with support members for fixing the pipeline. Each limiting part is equipped with a limiting member for pressing against the pipeline.

[0005] By adopting the above technical solution, this device can achieve stable pipeline transportation without large hoisting equipment. The initial positioning of the pipeline is achieved through the fixing groove of the base and the support members at both ends. Combined with the limiting members on the limiting part, the pipeline is fixed at multiple points, effectively preventing displacement, sliding, or collision during transportation. The omnidirectional wheel design gives the device high mobility in narrow pits, allowing for single-person operation of pipeline transportation and positioning adjustments, significantly reducing worker labor intensity and shortening the construction cycle. It is particularly suitable for municipal pipeline installation operations in densely populated urban areas.

[0006] Optionally, the upper surface of the base is provided with limiting holes on both sides for the insertion of the limiting part. Each limiting hole has a positioning hole on its inner sidewall and a locking rod passes through each positioning hole. The limiting part has a corresponding locking groove for the locking rod to be inserted. One end of the locking rod is connected to a fixing magnet. A metal sheet for the fixing magnet to be attracted is embedded on the outer sidewall of the base.

[0007] By adopting the above technical solution, the limiting post is inserted into the limiting hole, and then the locking rod is inserted into the locking groove after passing through the positioning hole. The fixing magnet on the locking rod is attracted to the metal plate, realizing the quick assembly and disassembly and stable positioning of the limiting part. The installation and disassembly of the limiting part can be completed without additional tools, which significantly improves the efficiency of on-site assembly. It is particularly suitable for construction environments with limited space, such as narrow streets or old urban areas, effectively shortening the deployment time of pipeline transportation devices and reducing manual operation steps.

[0008] Optionally, the limiting component includes a limiting screw threadedly connected to the limiting part, one end of the limiting screw being connected to a limiting post for pressing against the pipe, and the other end being connected to a drive handwheel.

[0009] By adopting the above technical solution, the limit post can be precisely adjusted by rotating the handwheel, ensuring that the limit post can be pressed against the outer wall of the pipeline. This makes the pipeline fixing process simpler and more controllable, avoiding the errors and loosening risks of traditional manual fixing, ensuring that the pipeline maintains a stable position during transportation, and significantly reducing the rework rate caused by pipeline displacement during construction.

[0010] Optionally, a drive handle is connected to the drive handwheel.

[0011] By adopting the above technical solution, a drive handle is added to the drive handwheel. The drive handle provides a point of leverage for construction workers, making it easier to move the base. In addition, the drive handle makes it easier for workers to turn the limit screw in narrow spaces, significantly reducing labor intensity. This is especially suitable for operation scenarios in densely populated urban areas, avoiding construction delays and worker fatigue caused by strenuous operation. After the pipeline is moved to the designated position, the worker turns the limit screw through the drive handle, causing the limit screw to move away from the pipeline. This causes the drive handle to press against the inner wall of the pit, thereby restricting the movement of the base and further improving construction safety.

[0012] Optionally, each of the limiting posts is provided with a connecting hole for the locking rod to pass through, and the cross-section of the limiting post is semi-circular.

[0013] By adopting the above technical solution, after removing the two limiting parts from the base, the drive handwheel is rotated to adjust the relative position of the two limiting posts so that the connecting holes on the two limiting posts are aligned with each other. Then, the locking rod is inserted into the connecting hole to fix the two limiting parts together. On the one hand, it is convenient to store the limiting parts. On the other hand, after the two limiting parts are fixed together, it is convenient for construction personnel to push the two limiting parts to move at the same time, thereby improving construction efficiency.

[0014] Optionally, one end of each of the limiting posts is connected to a resilient protective block.

[0015] By adopting the above technical solution, an elastic protective block is connected to the end of the limiting post, which absorbs the impact force during transportation through cushioning material. This design avoids direct collision between the pipe and rigid components, reducing surface damage and noise.

[0016] Optionally, the support member includes a support plate and a first support bar and a second support bar respectively installed at the upper and lower ends of the support plate. The base has an installation hole, the support plate is slidably connected to the installation hole, the upper end face of the base is rotatably connected to a locking post, the upper end of the locking post is vertically connected to a locking bar, and the first support bar has a fixing hole for the locking bar to pass through.

[0017] By adopting the above technical solution, after the pipeline is transported to the designated position, the support plate is moved down so that the first support bar is in close contact with the upper end face of the base. The locking bar passes through the fixing hole, and then the locking bar is rotated 90 degrees so that the locking bar is in close contact with the upper end face of the first support bar, thereby restricting the sliding of the support plate. This allows the second support bar to contact the bottom of the pit, making it easier to remove the limiting part later.

[0018] Optionally, sliding grooves are provided at both ends of the lower end face of the second support bar, and a connecting bar is slidably connected in each sliding groove. A fastening spring for pressing the connecting bar is connected between the connecting bar and the inner side wall of the sliding groove. Two connecting rings for the connecting bar to be inserted are connected to both ends of the lower end face of the base.

[0019] By adopting the above technical solution, the connecting strip is inserted into the connecting ring to form a locking structure, which restricts the downward sliding of the support plate, so that the support plate always extends from the upper end face of the base, thereby limiting the pipe and preventing the pipe from slipping off the base. On the other hand, when the pipe is transported to the designated position, the support plate is moved down, and the second support strip contacts the bottom of the pit. Under the action of the fastening spring, the connecting strip extends out of the sliding groove, thereby increasing the contact area between the second support strip and the bottom of the pit, providing better support for the base, further improving the stability of the base, and preventing the base from tipping over.

[0020] Optionally, a shock-absorbing column is connected to the mounting block, a shock-absorbing groove is provided on the limiting part, the shock-absorbing column is slidably connected in the shock-absorbing groove, and a shock-absorbing spring is sleeved on the shock-absorbing column, with one end of the shock-absorbing spring abutting against the mounting block and the other end abutting against the limiting part.

[0021] By adopting the above technical solution, the mounting block is connected to the shock-absorbing column, and the limiting part has a shock-absorbing groove and is fitted with a shock-absorbing spring, forming a vibration reduction system. This solution effectively absorbs ground bumps and transportation vibrations, avoiding pipeline damage or displacement caused by impact. It is especially suitable for complex urban road surfaces, significantly reducing the risk of damage during pipeline transportation and ensuring project quality.

[0022] Optionally, a plurality of mounting slots are provided on the inner side wall of the fixing slot, and a drive bearing is installed in each mounting slot, the drive bearing abutting against the outer side wall of the pipe.

[0023] By adopting the above technical solution, a drive bearing is embedded inside the fixed groove, forming a low-friction interface with the outer wall of the pipe. This design significantly reduces the moving resistance of the pipe on the base, making manual handling more labor-saving and efficient. It is particularly suitable for single-person operation in narrow foundation pits, directly shortening the construction cycle and reducing the labor intensity of workers, meeting the needs of municipal engineering for high-efficiency and low-burden operations.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The device can achieve stable pipeline transportation without large hoisting equipment. The initial positioning of the pipeline is achieved through the fixing groove of the base and the support members at both ends. The limiting members on the limiting part provide multi-point fixation of the pipeline, effectively preventing displacement, sliding, or collision during transportation. The omnidirectional wheel design gives the device high mobility in narrow pits, allowing for pipeline transportation and position adjustment by a single operator, significantly reducing labor intensity and shortening the construction cycle. It is particularly suitable for municipal pipeline installation operations in densely populated urban areas.

[0025] 2. A drive handle is added to the drive handwheel. The drive handle provides a leverage point for construction workers to easily move the base. In addition, the drive handle makes it easier for workers to turn the limit screw in narrow spaces, significantly reducing labor intensity. This is especially suitable for operation scenarios in dense urban areas, avoiding construction delays and personnel fatigue caused by laborious operation. After the pipeline is moved to the designated position, the worker turns the limit screw by the drive handle, causing the limit screw to move away from the pipeline. This causes the drive handle to press against the inner wall of the pit, thereby restricting the movement of the base and further improving construction safety.

[0026] 3. After removing the two limiting parts from the base, rotate the drive handwheel to adjust the relative position of the two limiting posts so that the connecting holes on the two limiting posts are aligned with each other. Then insert the locking rod into the connecting hole to fix the two limiting parts together. This makes it easier to store the limiting parts and also makes it easier for construction workers to push the two limiting parts to move at the same time after they are fixed together, thus improving construction efficiency.

[0027] 4. After the pipeline is transported to the designated position, the support plate is moved down so that the first support bar is in close contact with the upper surface of the base. The locking bar passes through the fixing hole. Then, the locking bar is rotated 90 degrees so that it is in close contact with the upper surface of the first support bar, thereby restricting the sliding of the support plate. This allows the second support bar to contact the bottom of the pit, making it easier to remove the limiting part later.

[0028] 5. The connecting strip engages with the connecting ring to form a locking structure, restricting the downward sliding of the support plate and ensuring that the support plate always extends from the upper surface of the base, thereby limiting the pipe and preventing it from slipping off the base. On the other hand, when the pipe is transported to the designated position, the support plate is moved down, and the second support strip contacts the bottom of the pit. Under the action of the fastening spring, the connecting strip extends from the sliding groove, thereby increasing the contact area between the second support strip and the bottom of the pit, providing better support for the base, further improving the stability of the base, and preventing the base from tipping over.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0037] This application discloses a municipal pipeline transportation device. Referring to Figures 1 and 2, it includes a base 1 for placing pipelines, and the base 1 is cuboid in shape. Limiting parts 2 are detachably connected to both sides of the upper surface of the base 1. Two mounting blocks 21 are installed on the lower surface of each limiting part 2, and each mounting block 21 is equipped with casters 22. A fixing groove 11 for placing the pipeline is provided on the base 1, and support members 3 for fixing the pipeline are provided at both ends of the upper surface of the base 1. Each limiting part 2 is equipped with a limiting member for pressing against the pipeline. This device can achieve stable pipeline transportation without large hoisting equipment. The fixing groove 11 of the base 1 and the support members 3 at both ends achieve initial positioning of the pipeline, and the limiting members on the limiting parts 2 provide multi-point fixation of the pipeline, effectively preventing displacement, sliding, or collision of the pipeline during transportation. The 22-wheel design gives the device high mobility in narrow pits, allowing a single person to operate it to transport and reposition the pipeline, greatly reducing the labor intensity of workers and shortening the construction cycle. It is especially suitable for municipal pipeline installation in densely populated urban areas.

[0038] Referring to Figures 1, 2, and 3, two limiting holes 12 are provided on both sides of the upper surface of the base 1 for the insertion of the limiting part 2. Each limiting hole 12 has a positioning hole 13 on its inner sidewall, and a locking rod 4 passes through each positioning hole 13. A corresponding locking groove 23 is provided on the limiting part 2 for the insertion of the locking rod 4. A fixing magnet 41 is fixedly connected to one end of the locking rod 4. A metal sheet (made of iron) is embedded on the outer sidewall of the base 1 for the fixing magnet 41 to attract. The limiting post 25 is inserted into the limiting hole 12, and then the locking rod 4 is inserted into the locking groove 23 after passing through the positioning hole 13. The fixing magnet 41 on the locking rod 4 is attracted to the metal sheet, achieving quick assembly and disassembly and stable positioning of the limiting part 2. The installation and disassembly of the limiting part 2 can be completed without additional tools, significantly improving on-site assembly efficiency. It is particularly suitable for construction environments with limited space, such as narrow streets or old urban areas, effectively shortening the deployment time of pipeline transportation devices and reducing manual operation steps. In addition, after the pipeline is transported to the designated location, the limiting part 2 can be removed from the base 1, and the pipeline can be temporarily placed in the designated location. The removed limiting part 2 can be reused. Only one pair of limiting parts 2 and several bases 1 are needed to place multiple pipelines to be installed in advance, thereby improving construction efficiency.

[0039] Referring to Figures 1 and 2, the limiting component includes a limiting screw 24 threadedly connected to the limiting part 2. One end of the limiting screw 24 is fixedly connected to a limiting post 25 for pressing against the pipe, and the other end is fixedly connected to a drive handwheel 26. By rotating the handwheel, the limiting post 25 can be precisely adjusted, ensuring that the limiting post 25 can press against the outer wall of the pipe. This makes the pipe fixing process simpler and more controllable, avoiding the errors and loosening risks of traditional manual fixing, ensuring that the pipe maintains a stable position during transportation, and significantly reducing the rework rate caused by pipe displacement during construction.

[0040] Referring to Figures 1, 2, and 3, a drive handle 27 is fixedly connected to the drive handwheel 26. The drive handle 27 provides a leverage point for construction workers, facilitating the movement of the base 1. Furthermore, the drive handle 27 allows workers to more easily rotate the limiting screw 24 in confined spaces, significantly reducing labor intensity, especially suitable for densely populated urban areas, avoiding construction delays and worker fatigue caused by strenuous operation. Once the pipeline has moved to the designated position, the worker rotates the limiting screw 24 using the drive handle 27, causing the limiting screw 24 to move away from the pipeline, thus pressing the drive handle 27 against the inner wall of the pit, thereby restricting the movement of the base 1 and further improving construction safety.

[0041] Referring to Figures 1, 2, and 3, each limiting post 25 has a connecting hole 251 for the locking rod 4 to pass through, and the cross-section of the limiting post 25 is semi-circular. One end of each limiting post 25 is fixedly connected to an elastic protective block 252 made of rubber. After removing the two limiting parts 2 from the base 1, rotate the drive handwheel 26 to adjust the relative position of the two limiting posts 25, aligning the connecting holes 251 on the two limiting posts 25. Then, insert the locking rod 4 into the connecting hole 251, thereby fixing the two limiting parts 2 together. This facilitates the storage of the limiting parts 2 and allows construction personnel to simultaneously push the two limiting parts 2, improving construction efficiency. The elastic protective block 252 fixedly connected to the end of the limiting post 25 absorbs the impact force during transportation through the cushioning material. This design avoids direct collision between the pipe and rigid components, reducing surface damage and noise.

[0042] Referring to Figures 2, 4, and 5, the support member 3 includes a support plate 31 and a first support bar 32 and a second support bar 33, which are respectively fixedly connected to the upper and lower ends of the support plate 31. The base 1 has mounting holes, and the support plate 31 is slidably connected to the mounting holes. A locking post 5 is rotatably connected to the upper surface of the base 1, and a locking bar 51 is vertically fixed to the upper end of the locking post 5. The first support bar 32 has a fixing hole 321 through which the locking bar 51 passes. After the pipeline is transported to the designated position, the support plate 31 is lowered so that the first support bar 32 is in close contact with the upper surface of the base 1, and the locking bar 51 passes through the fixing hole 321. Then, the locking bar 51 is rotated 90 degrees, so that the locking bar 51 is in close contact with the upper surface of the first support bar 32, thereby restricting the sliding of the support plate 31. This allows the second support bar 33 to contact the bottom of the pit, facilitating the subsequent removal of the limiting part 2.

[0043] Referring to Figures 2, 4, and 5, sliding grooves 331 are provided at both ends of the lower end face of the second support bar 33, and a connecting bar 6 is slidably connected in each sliding groove 331. A fastening spring 61 for pressing the connecting bar 6 is fixedly connected between the connecting bar 6 and the inner wall of the sliding groove 331. Two connecting rings 7 for the connecting bar 6 to be inserted are connected to both ends of the lower end face of the base 1. The connecting bar 6 is inserted into the connecting ring 7 to form a locking structure, which restricts the downward sliding of the support plate 31, so that the support plate 31 always extends from the upper end face of the base 1, thereby limiting the pipe and preventing the pipe from slipping off the base 1. On the other hand, when the pipe is transported to the designated position, the support plate 31 is moved down, and the second support bar 33 contacts the bottom of the pit. Under the action of the fastening spring 61, the connecting bar 6 extends out of the sliding groove 331, thereby increasing the contact area between the second support bar 33 and the bottom of the pit, providing better support for the base 1, further improving the stability of the base 1, and preventing the base 1 from tipping over.

[0044] Referring to Figures 2 and 4, a shock-absorbing column 211 is fixedly connected to the mounting block 21, and a shock-absorbing groove 28 is provided on the limiting part 2. The shock-absorbing column 211 is slidably connected within the shock-absorbing groove 28. A shock-absorbing spring 212 is sleeved on the shock-absorbing column 211, with one end of the spring 212 pressing against the mounting block 21 and the other end pressing against the limiting part 2. A drive bearing 112 is embedded inside the fixing groove 11, forming a low-friction interface with the outer wall of the pipeline. The shock-absorbing spring 212 can effectively absorb ground bumps and transportation vibrations, preventing pipeline damage or displacement caused by impact. It is especially suitable for complex urban road surfaces, significantly reducing the risk of damage during pipeline transportation and ensuring project quality.

[0045] Referring to Figures 1 and 2, several mounting slots 111 are formed on the inner sidewall of the fixing groove 11. Each mounting slot 111 houses a drive bearing 112, which abuts against the outer sidewall of the pipe. The drive bearing 112 forms a low-friction interface with the outer wall of the pipe. This design significantly reduces the moving resistance of the pipe on the base 1, making manual handling more labor-saving and efficient. It is particularly suitable for single-person operation in narrow foundation pits, directly shortening the construction cycle and reducing the labor intensity of workers, meeting the needs of municipal engineering for high-efficiency and low-burden operations.

[0046] The implementation principle of a municipal pipeline transportation device according to an embodiment of this application is as follows: This device can achieve stable transportation of pipelines without the need for large hoisting equipment. The initial positioning of the pipeline is achieved through the fixing groove 11 of the base 1 and the support members 3 at both ends. The limiting members on the limiting part 2 provide multi-point fixation of the pipeline, effectively preventing displacement, sliding or collision of the pipeline during transportation. The design of the universal wheels 22 gives the device high mobility in narrow pits, allowing a single person to operate the pipeline for transportation and position adjustment, greatly reducing the labor intensity of workers and shortening the construction cycle. It is particularly suitable for municipal pipeline installation operations in densely populated urban areas.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
