Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and in particular, to a water supply and drainage pipeline construction device. Background Art

[0002] With the gradual development of the urbanization process, as an important part of urban infrastructure, people have paid more and more attention to the municipal water supply and drainage problems. Municipal water supply and drainage projects can not only timely remove the accumulated water on the urban ground, provide industrial and domestic water, but also prevent the pollution of urban water resources. Common water supply pipes include galvanized steel pipes, ductile iron pipes, aluminum-plastic pipes, and plastic-lined steel pipes, etc.

[0003] Municipal rainwater pipes are usually connected in sequence by socket pipes. The construction process generally uses lifting equipment such as excavators to lift the pipes into the installation trench through lifting ropes and connect them with the previous pipes. This process requires the assistance of multiple workers to control the position of the pipes. During the docking process, it is easy to cause the pipes to collide, resulting in damage to the appearance of the pipes and safety accidents caused by personnel collisions. It is difficult to achieve stable docking, resulting in low construction efficiency. Therefore, corresponding improvements are made to solve this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a water supply and drainage pipeline construction device.

[0005] A water supply and drainage pipeline construction device proposed by the present invention includes a bottom plate. An opening is provided on the bottom plate. Handles are fixed at both ends of the bottom plate. A support plate is arranged in the opening. A plurality of L-shaped fixing frames are fixed at the top of the bottom plate at the corner positions. An electric push rod facing downwards is fixed at the top end of the fixing frame. The output shaft of the electric push rod is fixedly connected to the support plate. A positioning component and a propulsion component are also arranged on the top of the bottom plate. Support plates are arranged at the corners of the bottom of the bottom plate. A wheel shaft is fixed on the support plate. A roller is rotatably connected to the wheel shaft; Move the pipe onto the support plate, stabilize the pipe through the positioning component, then move the device to the trench through the handle. Then, extend the output shaft of the electric push rod to drive the support plate to move downwards until the pipe moves to the predetermined height and then stop. Then, push the pipe along the direction of the support plate through the propulsion component until the two pipes are butted together. In this way, the entire docking process will be quite stable.

[0006] Preferably, the propulsion assembly includes a first bracket fixed to the top of the pallet. There is a socket on the first bracket, and a transverse sliding plate is inserted into the socket. The inner end of the sliding plate is rotatably connected to a rotating shaft, and a rotating plate is fixed to the bottom end of the rotating shaft. The first bracket is also rotatably connected to a shaft column and a first screw rod respectively located above and below the socket. The first screw rod is threadedly connected to the sliding plate, and the shaft column and the first screw rod are connected by a synchronization assembly. A second bevel gear capable of axially moving along the shaft column is sleeved on the shaft column. A vertical plate is provided on the top of the sliding plate, and the second bevel gear is rotatably connected to the vertical plate. A first motor is fixed to the outer side of the first bracket, and the output shaft of the first motor is fixedly connected to the end of the shaft column. When the first motor is started, the output shaft of the first motor drives the shaft column to rotate, and then the shaft column drives the first screw rod to rotate through the synchronization assembly. When the shaft column rotates, it synchronously drives the second bevel gear to rotate, and then the second bevel gear meshes with the first bevel gear to drive the rotating shaft and the rotating plate to rotate, and the rotating plate will push the pipeline forward. Then when the first screw rod rotates, it will drive the sliding plate to move forward, and the sliding plate will synchronously drive the rotating plate, the vertical plate and the second bevel gear to move forward, so that the rotating plate will continuously push the pipeline forward.

[0007] Preferably, the synchronization assembly includes a pair of first synchronous wheels, and the two first synchronous wheels are respectively fixedly sleeved on the shaft column and the first screw rod, and the two first synchronous wheels are connected by a first synchronous belt. In this way, through the transmission cooperation between the first synchronous wheels and the first synchronous belt, the shaft column and the first screw rod can be rotated synchronously.

[0008] Preferably, a sliding groove is provided on the circumferential inner wall of the second bevel gear, and a sliding strip forming a sliding fit with the sliding groove is provided on the circumferential outer wall of the shaft column. Through the sliding fit formed between the sliding groove and the sliding strip, the second bevel gear can axially move along the shaft column.

[0009] Preferably, the propulsion assembly includes a second bracket fixed to the top of the pallet. A second screw rod is rotatably connected to the second bracket, and a push plate is threadedly connected to the second screw rod. The bottom end of the push plate is in contact with the top surface of the pallet. A second motor is fixed to the outer side of the second bracket, and second synchronous wheels are installed on both the output shaft of the second motor and the second screw rod, and the two second synchronous wheels are connected by a second synchronous belt. After the second motor is started, the output shaft of the second motor will drive the second screw rod to rotate through the transmission cooperation of the second synchronous wheels and the second synchronous belt. Then the rotating second screw rod will drive the push plate to move forward, and the push plate will continuously push the pipeline forward.

[0010] Preferably, a guide post is fixed to the outer side of the push plate, and the free end of the guide post passes through the second bracket. The stability of the push plate during the moving process can be improved through the guide post.

[0011] Preferably, the positioning assembly includes two positioning plates. A sliding opening is formed at the top of the support plate, and the positioning plates are slidably connected within the sliding opening. A pair of fixed seats are fixed to the bottom of the support plate, and the same bidirectional screw is rotatably connected between the two fixed seats. The bidirectional screw is threadedly connected to both positioning plates. After placing the pipeline between the two positioning plates, rotate the bidirectional screw, and then the two positioning plates will approach each other, centering and positioning the pipeline, making the pipeline stable.

[0012] Preferably, the support plate is fixedly connected to the bottom plate.

[0013] Preferably, the support plate is slidably connected to the bottom plate. Two groups of legs are symmetrically distributed front and back at the bottom of the bottom plate. A notch is formed in the bottom plate at the position where the support plate is installed, and a toothed bar is rotatably connected within the notch. Two toothed plates are fixed to the front and rear ends of the support plate respectively and are located within the notch. The toothed plates are meshed with the toothed bar. The support plate is meshed with the toothed bar through the tooth groove on the back. When the support plate moves downward, it will synchronously drive the toothed plates to move, and then the toothed plates will engage the toothed bar to drive the support plate to move upward, and then the legs will land to support the bottom plate. At this time, the support plate and the toothed bar will disengage from the meshed state, and the support plate can continue to move downward until it reaches the predetermined position, so that the device will be more stable during the docking process and will not shift randomly.

[0014] Compared with the prior art, the present invention provides a water supply and drainage pipeline construction device, which has the following beneficial effects: 1. A water supply and drainage pipeline construction device, by setting a support plate and a propulsion assembly, moves the pipeline onto the support plate, stabilizes the pipeline through the positioning assembly, then moves the device to the trench through the handle, and then the output shaft of the electric push rod extends to drive the support plate to move downward until the pipeline moves to the predetermined height and stops. Then, the pipeline is pushed along the direction of the support plate through the propulsion assembly until the two pipelines are butted together, so that the entire butting process will be quite stable.

[0015] 2. A water supply and drainage pipeline construction device, by setting a rotating plate, the output shaft of the first motor drives the shaft column to rotate, and then the shaft column drives the first screw to rotate through the synchronous assembly.

[0016] 3.

Then, the rotating second screw will drive the push plate to move forward, and the push plate will continuously push the pipeline.

[0017] 4. A water supply and drainage pipeline construction device. By setting a movable support plate, when the support plate moves downward, it will synchronously drive the toothed plate to move. Then, the toothed plate will engage with the toothed rod to drive the support plate to move upward, and then the support legs will land to support the bottom plate. At this time, the support plate and the toothed rod will disengage from the meshing state, and the support plate can continue to move downward until it reaches the predetermined position. In this way, the device can be more stable during the docking process and will not shift randomly. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the pipeline is pushed along the direction of the support plate 3 through the propulsion component until the two pipelines are butted together. In this way, the entire butting process will be quite stable.

[0023] In Embodiment 1, the propulsion assembly includes a first bracket 11 fixed to the top of the pallet 3. A socket 12 is provided on the first bracket 11. A transverse sliding plate 13 is inserted into the socket 12. The inner end of the sliding plate 13 is rotatably connected to a rotating shaft 14. A rotating plate 10 is fixed to the bottom end of the rotating shaft 14. The first bracket 11 is also rotatably connected to a shaft column 16 and a first screw 19 respectively located above and below the socket 12. The first screw 19 is threadedly connected to the sliding plate 13. The shaft column 16 and the first screw 19 are connected by a synchronization assembly. A second bevel gear 22 capable of moving axially along the shaft column 16 is sleeved on the shaft column 16. A vertical plate 17 is provided on the top of the sliding plate 13. The second bevel gear 22 is rotatably connected to the vertical plate 17. A first motor 15 is fixed to the outer side surface of the first bracket 11. The output shaft of the first motor 15 is fixedly connected to the end of the shaft column 16. When the first motor 15 is started, the output shaft of the first motor 15 drives the shaft column 16 to rotate. Then, the shaft column 16 drives the first screw 19 to rotate through the synchronization assembly. When the shaft column 16 rotates, it synchronously drives the second bevel gear 22 to rotate. Then, the second bevel gear 22 meshes with the first bevel gear 18 to drive the rotating shaft 14 and the rotating plate 10 to rotate, and the rotating plate 10 will push the pipeline forward. Then, when the first screw 19 rotates, it will drive the sliding plate 13 to move forward, and the sliding plate 13 will synchronously drive the rotating plate 10, the vertical plate 17 and the second bevel gear 22 to move forward, so that the rotating plate 10 will continuously push the pipeline forward.

[0024] Among them, the synchronization assembly includes a pair of first synchronous wheels 20. The two first synchronous wheels 20 are respectively fixedly sleeved on the shaft column 16 and the first screw 19. The two first synchronous wheels 20 are connected by a first synchronous belt 21. In this way, through the transmission cooperation between the first synchronous wheels 20 and the first synchronous belt 21, the shaft column 16 and the first screw 19 can be made to rotate synchronously.

[0025] Among them, a chute 23 is provided on the circumferential inner wall of the second bevel gear 22. A sliding strip 24 forming a sliding fit with the chute 23 is provided on the circumferential outer wall of the shaft column 16. Through the sliding fit formed between the chute 23 and the sliding strip 24, the second bevel gear 22 can be made to move axially along the shaft column 16.

[0026] In Embodiment 2, the propulsion assembly includes a second bracket 26 fixed to the top of the pallet 3. A second screw rod 27 is rotatably connected to the second bracket 26. A push plate 25 is threadedly connected to the second screw rod 27. The bottom end of the push plate 25 is in contact with the top surface of the pallet 3. A second motor 28 is fixed to the outer side surface of the second bracket 26. Second synchronous pulleys 29 are installed on both the output shaft of the second motor 28 and the second screw rod 27. The two second synchronous pulleys 29 are connected by a second synchronous belt 30. After the second motor 28 is started, the output shaft of the second motor 28 will drive the second screw rod 27 to rotate through the transmission cooperation of the second synchronous pulley 29 and the second synchronous belt 30. Then, the rotating second screw rod 27 will drive the push plate 25 to move forward, and the push plate 25 will continuously push the pipeline forward.

[0027] Furthermore, guide posts 31 are fixed to the outer side surface of the push plate 25. The free ends of the guide posts 31 pass through the second bracket 26. The stability of the movement process of the push plate 25 can be improved through the guide posts 31.

[0028] Among them, the positioning assembly includes two positioning plates 33. A sliding opening 32 is formed in the top of the pallet 3. The positioning plates 33 are slidably connected in the sliding opening 32. A pair of fixed seats 34 are fixed to the bottom of the pallet 3. The same bidirectional screw rod 35 is rotatably connected between the two fixed seats 34. The bidirectional screw rod 35 is threadedly connected to both of the two positioning plates 33. After the pipeline is placed between the two positioning plates 33, the bidirectional screw rod 35 is rotated. Then, the two positioning plates 33 will approach each other, positioning the pipeline in the middle and keeping the pipeline stable.

[0029] In Embodiment 3, the support plate 6 is fixedly connected to the bottom plate 1.

[0030] Considering that the support plate 6 is directly fixedly connected to the bottom plate 1, the device is prone to displacement through the rollers 7 during the docking process, thus affecting the precise docking. Therefore, in Embodiment 4, the support plate 6 and the bottom plate 1 are slidably connected. Two groups of legs 39 are symmetrically distributed front and back and fixed to the bottom of the bottom plate 1. A notch 36 is formed in the bottom plate 1 at the position where the support plate 6 is installed. A toothed bar 37 is rotatably connected in the notch 36. Two toothed plates 38 are fixed to both the front and rear ends of the pallet 3 and are respectively located in the notch 36. The toothed plates 38 are meshed with the toothed bar 37. The support plate 6 is meshed with the toothed bar 37 through the tooth groove on the back. When the pallet 3 moves downward, it will synchronously drive the toothed plate 38 to move. Then, the toothed plate 38 will engage the toothed bar 37 to drive the support plate 6 to move upward. Then, the legs 39 will touch the ground to support the bottom plate 1. At this time, the support plate 6 and the toothed bar 37 will disengage from the meshed state, and the pallet 3 can continue to move downward until it reaches the predetermined position. In this way, the device can be more stable during the docking process and will not shift randomly.
