Description

Technical Field

[0001] The utility model relates to the field of water supply and drainage devices, in particular to a pipe delivery device for municipal water supply and drainage construction. Background Art

[0002] The municipal water supply and drainage system is the cornerstone of urban operations and is related to the supply and discharge of water. In this system, plastic pipes have surpassed traditional materials such as cast iron pipes and galvanized steel pipes with their advantages such as light weight, corrosion resistance, low water flow resistance, energy saving, easy installation and low cost. They have become the mainstream choice for modern water supply and drainage pipelines, providing a solid guarantee for the sustainable development of cities.

[0003] When laying long-distance pipelines, since the pipelines need to be constructed in sections and are heavy, pipe delivery and docking become a difficult problem for construction workers. Currently, suspension equipment is widely used for pipeline lifting, but the pipeline shaking problem occurs frequently during the suspension process, resulting in uneven placement of the pipelines. At the same time, for long pipelines, both ends are prone to falling due to gravity during suspension, which will cause pipeline deformation and reduce the quality of pipeline construction.

[0004] Therefore, in order to address the problem that the pipes may shake and deform when they are hoisted using suspension equipment, a pipe delivery device for municipal water supply and drainage construction can be designed. Through a threaded transmission structure and a connecting rod structure, the plastic pipes can be smoothly lifted and transported while avoiding the problem of shaking and deformation of the pipes. Utility Model Content

[0005] In order to overcome the problem of shaking and deformation of pipelines when using suspension equipment to lift pipelines.

[0006] The technical solution of the utility model is: a pipe delivery device for municipal water supply and drainage construction, including a transport vehicle, a ditch, a U-shaped bracket, wheels, axles, a support block, a guide plate, rollers and a lifting assembly; the U-shaped bracket is placed in the ditch, and two axles are symmetrically installed at the lower end of the U-shaped bracket, and wheels are installed at the front and rear ends of each axle, the support block is fixedly connected to the rear end of the U-shaped bracket and the support block is located at the upper end of the edge of the ditch, the lower end of the support block is installed with rollers, the upper end of the support block is fixedly connected with the guide plate, the guide plate is composed of an inclined plate and a cross plate, one end of the inclined plate is connected to the unloading bin of the transport vehicle, and the cross plate extends backward to the front end of the receiving plate in the lifting assembly, and the lifting assembly is installed in the U-shaped bracket.

[0007] Preferably, the transport vehicle serves as the main carrier for pipeline transportation and is responsible for transporting the water supply and drainage pipes from the storage location to the construction site. In municipal water supply and drainage construction, the excavation and laying of ditches are key steps. The ditch in the device serves as the track or support base of the pipe delivery device, and the U-shaped bracket serves as the installation base of the lifting component, while being able to move in the ditch. The support block provides additional support force to ensure that the guide plate can stably support the plastic pipe. At the same time, the roller at the lower end of the support block can roll on the edge of the ditch, so that the support block cooperates with the U-shaped bracket to move in the ditch, and the guide plate at the upper end of the support block further guides the plastic pipe into the U-shaped bracket. The design of the guide plate enables the plastic pipe to remain stable and stable during unloading, reducing impact and damage to the pipe. The lifting component is responsible for moving the plastic pipe up and down so that the plastic pipe enters the ditch.

[0008] Preferably, a rotating support seat is fixedly connected to the right inner wall of the U-shaped bracket, and a rotating motor is installed at the left end of the U-shaped bracket. The rotating support seat supports and allows the bidirectional threaded rod to rotate inside it to ensure stability during rotation. The rotating motor provides power to drive the bidirectional threaded rod to rotate.

[0009] Preferably, a coupling is installed at the left end of the bidirectional threaded rod and is connected to the output shaft of the rotating motor through the coupling. The right end of the bidirectional threaded rod is rotatably connected to the rotating support seat. The outer walls of the left and right ends of the bidirectional threaded rod are provided with external threads in opposite directions. The bidirectional threaded rod is connected to the output shaft of the rotating motor through the coupling to achieve power reception. At the same time, through the rotational motion, the No. 1 threaded sleeve and the No. 2 threaded sleeve are driven to move in relative or opposite directions.

[0010] Preferably, an internal thread that matches the external thread on the left outer wall of the two-way threaded rod is formed in the No. 1 threaded sleeve, and the left end of the two-way threaded rod is threadedly connected to the No. 1 threaded sleeve. An internal thread that matches the external thread on the right outer wall of the two-way threaded rod is formed in the No. 2 threaded sleeve, and the right end of the two-way threaded rod is threadedly connected to the No. 2 threaded sleeve. The No. 1 threaded sleeve and the No. 2 threaded sleeve move in relative or opposite directions according to the rotation direction of the two-way threaded rod, thereby driving the connecting rod to rotate, and then causing the receiving plate to rise or fall.

[0011] Preferably, the lifting assembly includes a connecting shaft and a receiving plate; the front and rear ends of the No. 1 threaded sleeve and the No. 2 threaded sleeve are fixedly connected with the connecting shaft, and the receiving plate for placing the plastic pipe is installed in the U-shaped bracket. The connecting shaft connects the No. 1 threaded sleeve, the No. 2 threaded sleeve and the connecting rod, and converts the movement of the No. 1 threaded sleeve and the No. 2 threaded sleeve into the lifting movement of the receiving plate. This design enables the connecting rod to rotate with the movement of the threaded sleeve, thereby driving the lifting and lowering of the receiving plate. The receiving plate places and supports the plastic pipe, and moves with the lifting and lowering of the connecting rod, thereby driving the plastic pipe to descend.

[0012] Preferably, two support plates are fixed symmetrically on the left and right sides of the lower end of the connecting plate, a fixed shaft is fixedly connected between the two support plates, the lower end of the connecting rod is rotatably connected to the outer wall of the connecting shaft, and the upper end of the connecting rod is rotatably connected to the outer wall of the fixed shaft. The support plate and the fixed shaft provide support and rotation fulcrum for the connecting rod, ensuring that the connecting rod can rotate stably, thereby driving the connecting plate to move.

[0013] Preferably, an arc-shaped limit groove adapted to the plastic pipe is formed at the upper end of the receiving plate, and a protective plate is fixedly connected to the front end of the U-shaped bracket to prevent the plastic pipe from falling. The arc-shaped limit groove is adapted to the plastic pipe to ensure that the pipe is stable and does not shake when placed, and the protective plate is used to prevent the plastic pipe from accidentally falling when entering the limit groove, thereby ensuring that the plastic pipe is not damaged.

The transport vehicle 1 is used as the main carrier for pipeline transportation and is responsible for The water supply and drainage pipes are transported from the storage location to the construction site. In the municipal water supply and drainage construction, the excavation and laying of the ditch 2 are key steps. The ditch 2 in the device serves as the track or support base of the pipe delivery device, and the U-shaped bracket 3 serves as the installation base of the lifting component, while it can move in the ditch 2. The support block 6 provides additional support force to ensure that the guide plate 7 can stably support the plastic pipe. At the same time, the roller 8 at the lower end of the support block 6 can roll on the edge of the ditch 2, so that the support block 6 cooperates with the U-shaped bracket 3 to move in the ditch 2, and the guide plate 7 at the upper end of the support block 6 further guides the plastic pipe into the U-shaped bracket 3. The design of the guide plate 7 enables the plastic pipe to remain stable and stable during the unloading process, reducing the impact and damage to the pipe. The lifting component is responsible for moving the plastic pipe up and down so that the plastic pipe enters the ditch 2.

[0026] See also Figure 4 and Figure 6In this embodiment, the right inner wall of the U-shaped bracket 3 is fixedly connected with a rotating support seat 9, and a rotating motor 10 is installed at the left end of the U-shaped bracket 3. A coupling 12 is installed at the left end of the bidirectional threaded rod 11 and is connected to the output shaft of the rotating motor 10 through the coupling 12. The right end of the bidirectional threaded rod 11 is rotatably connected to the rotating support seat 9. The outer walls of the left and right ends of the bidirectional threaded rod 11 are provided with external threads in opposite directions. The No. 1 threaded sleeve 13 is provided with an internal thread that matches the external thread on the left outer wall of the bidirectional threaded rod 11. The left end of the bidirectional threaded rod 11 is threadedly connected to the No. 1 threaded sleeve 13, and the No. 2 threaded sleeve 14 is provided with an internal thread that matches the external thread on the right outer wall of the bidirectional threaded rod 11.

The rotating support seat 9 supports and allows the bidirectional threaded rod 11 to rotate therein to ensure stability during rotation. The rotating motor 10 provides power to drive the bidirectional threaded rod 11 to rotate. The bidirectional threaded rod 11 is connected to the output shaft of the rotating motor 10 through a coupling 12 to receive power. At the same time, through the rotational movement, the No. 1 threaded sleeve 13 and the No. 2 threaded sleeve 14 are driven to move in relative or opposite directions. The No. 1 threaded sleeve 13 and the No. 2 threaded sleeve 14 move in relative or opposite directions according to the rotation direction of the bidirectional threaded rod 11, thereby driving the connecting rod 19 to rotate, and then the receiving plate 16 rises or falls.

[0027] See also Figure 5 and Figure 6 In this embodiment, the lifting assembly includes a connecting shaft 15 and a receiving plate 16; the front and rear ends of the No. 1 threaded sleeve 13 and the No. 2 threaded sleeve 14 are fixedly connected with the connecting shaft 15, and a receiving plate 16 for placing the plastic pipe is installed in the U-shaped bracket 3. The lower end of the receiving plate 16 is symmetrically fixed with two support plates 17, and a fixed shaft 18 is fixedly connected between the two support plates 17. The lower end of the connecting rod 19 is rotatably connected to the outer wall of the connecting shaft 15, and the upper end of the connecting rod 19 is rotatably connected to the outer wall of the fixed shaft 18. The upper end of the receiving plate 16 is provided with an arc-shaped limiting groove 20 adapted to the plastic pipe. The front end of the U-shaped bracket 3 is fixedly connected with a protective plate 21 for preventing the plastic pipe from falling. The connecting shaft 15 connects the No. 1 threaded sleeve 13 and the No. 2 threaded sleeve 14. The threaded sleeve 14 and the connecting rod 19 convert the movement of the No. 1 threaded sleeve 13 and the No. 2 threaded sleeve 14 into the lifting and lowering movement of the receiving plate 16. This design enables the connecting rod 19 to rotate with the movement of the threaded sleeve, thereby driving the receiving plate 16 to rise and fall. The receiving plate 16 places and supports the plastic pipe, and moves with the lifting and lowering of the connecting rod 19, thereby driving the plastic pipe to descend. The support plate 17 and the fixed shaft 18 provide support and rotation fulcrum for the connecting rod 19 to ensure that the connecting rod 19 can rotate stably, thereby driving the receiving plate 16 to move. The arc-shaped limit groove 20 is adapted to the plastic pipe to ensure that the pipe is stable and does not shake when placed, and the protective plate 21 is used to prevent the plastic pipe from accidentally falling when entering the limit groove 20 to ensure that the plastic pipe is not damaged.

[0028] In the operation process, the construction personnel first park the transport vehicle 1 at the edge of the ditch 2, and then slide the U-shaped bracket 3 along the ditch 2 to the front end of the unloading bin of the transport vehicle 1 to ensure that the guide plate 7 is docked with the unloading bin. At this time, the plastic pipe is smoothly rolled along the guide plate 7 to the limit groove 20 on the receiving plate 16. The limit groove 20 perfectly matches the shape of the pipe, effectively preventing the pipe from shaking. At the same time, the protective plate 21 effectively curbs the risk of slipping due to excessive rolling of the pipe.

[0029] Next, the rotating motor 10 is started, and the rotation of the rotating motor 10 drives the bidirectional threaded rod 11 to rotate. By utilizing the interaction principle of the threads, the No. 1 threaded sleeve 13 and the No. 2 threaded sleeve 14 move toward each other in the U-shaped bracket 3. This movement is converted into a stable descent of the receiving plate 16 through the connection and transmission of the connecting rod 19, and then the plastic pipe is slowly sent into the ditch 2.

[0030] After the laying of one section of the pipeline is completed, the transport vehicle 1 is again controlled to move forward a certain distance to meet the laying requirements of the next section of the pipeline.

[0031] Through the above steps, the pipe delivery device of the municipal water supply and drainage construction has a compact structure and is easy to operate. It not only effectively reduces the impact and damage of the pipeline during transportation and unloading, but also ensures that the pipeline enters the ditch 2 smoothly through the setting of the guide plate 7 and the protective plate 21, thereby reducing the workload of the construction personnel, improving the construction efficiency and quality of the staff, and solving the problem of shaking and deformation of the pipeline when the pipeline is hoisted using suspension equipment.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
