[0014] A construction method for a construction butt-pushing device of a water supply pipe network, the method comprising the following steps:

[0015] Step 1: Place a plurality of water supply pipes for butt joint fixation inside the storage housing, and drive the rollers at the bottom of the storage housing and the support frame through the control handle, so that the storage housing pushes the water supply pipes inside towards the butt joint position of the water supply pipe network;

[0016] Step 2: Through the action of the pipeline conveying mechanism, convey the water supply pipes inside the storage housing upwards along the circular through-hole towards the upper part of the support frame. The water supply pipes move into the arc of the bottom of the arc placement block in the middle section of the movable strip, and are limited by the action of the pipeline limiting mechanism. Then, through the action of the rotation adjustment mechanism, the rotating shaft is rotated and adjusted, and the U-shaped strip is driven to rotate synchronously, so as to adjust the flipping angle of the two arc placement blocks. Then, through the action of the displacement mechanism, adjust the distance between the U-shaped strip and the movable strip, so that the two arc placement blocks move towards the butt joint position of the branch of the water supply pipe network;

[0017] Step 3: Make the arc placement block at one end of the bottom of the movable strip fit with the branch of the water supply pipe network, and limit the arc placement block at one end of the bottom of the movable strip on the branch of the water supply pipe network through the action of the pipeline limiting mechanism, so that the branch of the water supply pipe network and the butt-jointed and installed water supply pipe are coaxially arranged, and are respectively limited by the two arc placement blocks, ensuring that one end of the water supply pipe and the branch of the water supply pipe network can be accurately butted.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the action of the pipeline limiting mechanism, the arc placement block at one end of the bottom of the movable strip is limited on the branch of the water supply pipe network, so that the branch of the water supply pipe network and the butt-jointed and installed water supply pipe are coaxially arranged, and are respectively limited by the two arc placement blocks, ensuring that one end of the water supply pipe and the branch of the water supply pipe network can be accurately butted. When fixing and butting one end of the water supply pipe on the branch of the water supply pipe network, the water supply pipe can be effectively supported and limited by the arc placement block, so that one end of the water supply pipe can be stably welded on the branch of the water supply pipe network, improving the butt joint efficiency of the water supply pipe network and shortening the construction period.

[0020] 2. After the arc placement block at one end of the bottom of the movable strip contacts the branch of the water supply pipe network, the branch of the water supply pipe network is limited in the arc of the bottom of the corresponding arc placement block through the action of the pipeline limiting mechanism, so that the water supply pipe clamped and limited on the arc placement block in the middle section of the bottom of the movable strip and the branch of the water supply pipe network are coaxially arranged. Thus, when the water supply pipe and the branch of the water supply pipe network are welded and fixed, one end of the water supply pipe and the branch of the water supply pipe network always remain butted and are supported and limited.

[0021] 3. When the two clamping rollers move in opposite directions, they drive the corresponding connecting shafts to rotate in opposite directions. The ratchets on the connecting shafts are no longer restricted by the elastic abutting pieces during the reverse rotation. Therefore, when the clamping rollers move in the opposite direction along the contact surface of the water supply pipe, they can rotate cooperatively along the surface of the water supply pipe through the contact friction force, thereby reducing the reverse pulling force on the water supply pipe when the clamping rollers move in the opposite direction, reducing the influence of the reverse pulling force generated at the welded joints of the water supply pipe and the branch of the water supply pipe network. After the round pin moves from the clamping section back into the separation section, the two clamping rollers move away from each other and release the contact with the surface of the water supply pipe, facilitating the return to the initial position and the next pipe docking.

[0022] 4. When the pushing bar is located at the communication position of the circular through-hole and the strip-shaped groove, the water supply pipe is completely pushed out of the storage housing. When the output shaft of the fourth motor rotates in the reverse direction and drives the pushing bar to return, the piston shaft of the second hydraulic cylinder moves in the reverse direction to drive the pushing bar to move downward, preventing the pushing bar from coming into contact with and blocking one end of the water supply pipe that falls between the two arc-shaped grooves during the return process, ensuring the continuous pushing of the water supply pipe.

DETAILED DESCRIPTION

[0035] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0036] like Figures 1 to 11 A water supply network construction docking and pushing device shown in the figure comprises a material storage shell 1, a support frame 2 is fixedly connected to the bottom of one end of the material storage shell 1, rollers 3 are rotatably connected to both sides of the bottom of the material storage shell 1 and the support frame 2, a rotating shaft 4 is rotatably connected to one end of the material storage shell 1 close to the support frame 2, a U-shaped bar 5 is fixedly connected to the rotating shaft 4, a rotating adjustment mechanism is connected to the rotating shaft 4, a movable bar 6 is arranged at the bottom of the U-shaped bar 5, and a displacement mechanism is connected between the movable bar 6 and the U-shaped bar 5;

[0037] An arc-shaped placement block 7 is fixedly connected to the middle section at the bottom of the movable bar 6 and one end away from the storage housing 1. A pipe limiting mechanism is connected to each arc-shaped placement block 7. A circular through-hole 8 is provided on one side of the storage housing 1 close to the support frame 2. The arc surfaces of the two arc-shaped placement blocks 7 are coaxially arranged with the circular through-hole 8. A pipe conveying mechanism is connected to the storage housing 1. A handle 9 is fixedly connected to one end of the support frame 2 away from the storage housing 1. During operation, in the prior art, when docking a water supply pipe, it is usually necessary to transport the water supply pipe to the docking area and then perform docking and installation. It is difficult for the water supply pipe to accurately dock with the branch of the water supply network during the docking process. And during the docking process, the staff needs to fix and seal the docking position. It is difficult to effectively support and limit the water supply pipe during docking, thus reducing the docking efficiency of the water supply network and prolonging the construction period of the water supply network. This technical solution can solve the above problems. The specific working method is as follows: Place multiple water supply pipes for docking and fixing inside the storage housing 1, and drive the rollers 3 at the bottom of the storage housing 1 and the support frame 2 to roll by controlling the handle 9, so that the storage housing 1 pushes the water supply pipes inside towards the docking position of the water supply network. After the storage housing 1 moves to one side of the water supply network, the water supply pipes inside the storage housing 1 are transported upward along the circular through-hole 8 to above the support frame 2 through the action of the pipe conveying mechanism. The water supply pipes move into the arc surface at the bottom of the arc-shaped placement block 7 in the middle section of the movable bar 6 and are limited by the action of the pipe limiting mechanism. Then, the rotating shaft 4 is rotated and adjusted through the action of the rotation adjustment mechanism, and the U-shaped bar 5 is driven to rotate synchronously, so as to adjust the flipping angle of the two arc-shaped placement blocks 7. Then, the distance between the U-shaped bar 5 and the movable bar 6 is adjusted through the action of the displacement mechanism, so that the two arc-shaped placement blocks 7 move towards the docking position of the branch of the water supply network. The arc-shaped placement block 7 at one end of the bottom of the movable bar 6 is used to fit with the branch of the water supply network, and the arc-shaped placement block 7 at one end of the bottom of the movable bar 6 is limited on the branch of the water supply network through the action of the pipe limiting mechanism, so that the branch of the water supply network and the water supply pipe for docking and installation are coaxially arranged, and are respectively limited by the two arc-shaped placement blocks 7, ensuring that one end of the water supply pipe and the branch of the water supply network can be accurately docked. And when one end of the water supply pipe is fixedly docked on the branch of the water supply network, the water supply pipe can be effectively supported and limited by the arc-shaped placement block 7, so that one end of the water supply pipe can be stably welded on the branch of the water supply network, improving the docking efficiency of the water supply network and shortening the construction period.

[0038] As a further embodiment of the present invention, the rotation adjustment mechanism includes a mating gear 10 and a first motor 11. The mating gear 10 is fixedly connected to the rotating shaft 4, and the first motor 11 is fixedly installed on the storage housing 1. A driving gear 12 is fixedly connected to the output shaft of the first motor 11, and the driving gear 12 meshes with the mating gear 10. During operation, the output shaft of the first motor 11 rotates to drive the driving gear 12 to rotate synchronously. Through the meshing action of the driving gear 12 and the mating gear 10, the rotating shaft 4 rotates in cooperation along the rotating connection of the storage housing 1, driving the U-shaped strip 5 and the movable strip 6 to rotate synchronously, thereby adjusting the angle between the arc-shaped placement block 7 and the branch of the water supply pipe network, so that the arc-shaped surface at the bottom of the arc-shaped placement block 7 can face the branch of the water supply pipe network, facilitating the arc-shaped placement block 7 at one end of the bottom of the movable strip 6 to limit the branch of the water supply pipe network.

[0039] As a further embodiment of the present invention, the displacement mechanism includes two sliding strips 13. Both sliding strips 13 are fixedly connected to the top of the movable strip 6 and are slidably inserted into the U-shaped strip 5. Two first hydraulic cylinders 14 are fixedly installed inside the U-shaped strip 5. The piston shafts of the first hydraulic cylinders 14 penetrate through the U-shaped strip 5 and extend below the U-shaped strip 5 and are fixedly connected to the top of the movable strip 6. During operation, after the arc-shaped surface at the bottom of the arc-shaped placement block 7 faces the branch of the water supply pipe network through the action of the rotation adjustment mechanism, the piston shafts of the two first hydraulic cylinders 14 move synchronously, driving the movable strip 6 away from the U-shaped strip 5, causing the arc-shaped placement block 7 on the movable strip 6 to move synchronously and approach the branch of the water supply pipe network. The sliding strips 13 on the movable strip 6 move along the sliding insertion of the U-shaped strip 5 to limit the movement of the movable strip 6. When the arc-shaped placement block 7 at one end of the bottom of the movable strip 6 contacts the branch of the water supply pipe network, the branch of the water supply pipe network is limited in the arc-shaped surface at the bottom of the corresponding arc-shaped placement block 7 through the action of the pipeline limiting mechanism, so that the water supply pipe clamped and limited on the arc-shaped placement block 7 in the middle section of the bottom of the movable strip 6 is coaxially arranged with the branch of the water supply pipe network. Thus, when the water supply pipe and the branch of the water supply pipe network are welded and fixed, one end of the water supply pipe and the branch of the water supply pipe network always remain butted and are supported and limited.

[0040] As a further embodiment of the present invention, the pipeline limiting mechanism includes two mounting frames 15, which are fixedly connected to both sides of the arc-shaped placing block 7. The inside of each mounting frame 15 is slidably connected with a movable plate 16. An arc-shaped limiting strip 17 is fixedly connected to each movable plate 16. Both arc-shaped limiting strips 17 are located at the bottom of the arc-shaped placing block 7, and the arc-shaped surfaces of the arc-shaped limiting strips 17 correspond to the arc-shaped surface of the arc-shaped placing block 7. A bidirectional lead screw 18 is rotatably connected between the two mounting frames 15. Both movable plates 16 are threadedly connected to the bidirectional lead screw 18. A second motor 19 is fixedly installed on one of the mounting frames 15, and the output shaft of the second motor 19 is fixedly connected to one end of the bidirectional lead screw 18. During operation, the output shaft of the second motor 19 rotates to drive the bidirectional lead screw 18 to rotate. Through the threaded connection between the bidirectional lead screw 18 and the two movable plates 16, the two movable plates 16 move along the inside of the corresponding mounting frame 15 by the rotation of the bidirectional lead screw 18, so that the two movable plates 16 approach each other. When the two movable plates 16 approach each other, they drive the corresponding arc-shaped limiting strips 17 to move synchronously, so that the two arc-shaped limiting strips 17 approach each other. And through the arc-shaped surface on the arc-shaped limiting strip 17 being attached to the surface of the water supply pipeline, the water supply pipeline is limited in the arc-shaped surface at the bottom of the arc-shaped placing block 7. When the output shaft of the second motor 19 rotates in the reverse direction, the two arc-shaped limiting strips 17 move away from each other, thereby releasing the limitation of the water supply pipeline in the arc-shaped surface at the bottom of the arc-shaped placing block 7, enabling the two arc-shaped placing blocks 7 to respectively limit and release the limitation of the water supply network branch and the water supply pipeline.

[0041] As a further embodiment of the present invention, an installation groove 20 is opened at the bottom of the movable strip 6. A movable frame 21 is slidably connected inside the installation groove 20. An activity groove 22 is opened on the movable frame 21. Both sides inside the activity groove 22 are slidably connected with L-shaped plates 23. The bottom of both L-shaped plates 23 is rotatably connected with a connecting shaft 24. A clamping roller 25 is fixedly connected to each connecting shaft 24. A ratchet wheel 26 (as Figure 2 shown) is fixedly connected to the top of each connecting shaft 24. An elastic abutting piece 27 is fixedly connected to each L-shaped plate 23. One end of the elastic abutting piece 27 is respectively located on the side of the corresponding ratchet wheel 26. A first connecting ring 28 is fixedly inserted on the movable frame 21. A first lead screw 29 is rotatably connected inside the installation groove 20. The first lead screw 29 is threadedly connected inside the first connecting ring 28. A third motor 30 is fixedly installed at one end of the movable strip 6 (as Figure 3As shown, the output shaft of the third motor 30 is fixedly connected to one end of the first lead screw 29. On the top surface inside the installation groove 20, two guiding channel rails 31 are fixedly connected. The guiding channel rail 31 includes a separating section 3101 and a clamping section 3102. On the adjacent sides of the two L-shaped plates 23, circular pins 32 are fixedly connected respectively. One ends of the circular pins 32 are respectively located inside the corresponding guiding channel rails 31. The movable frame 21 is located between the circular through hole 8 and the arc-shaped placing block 7 in the middle section of the movable strip 6. During operation, when the water supply pipe moves along the circular through hole 8 to the arc surface at the bottom of the arc-shaped placing block 7 in the middle section of the movable strip 6, the water supply pipe is limited by the corresponding arc-shaped limiting strip 17. And when the arc-shaped placing block 7 at one end of the movable strip 6 is limited by the corresponding arc-shaped limiting strip 17 on the branch of the water supply network, the docking of the branch of the water supply network and the water supply pipe is completed. By rotating the output shaft of the third motor 30, the first lead screw 29 is driven to rotate unidirectionally. And through the threaded connection between the first lead screw 29 and the first connecting ring 28, the first connecting ring 28 drives the movable frame 21 to move along the sliding connection inside the installation groove 20, so that the two L-shaped plates 23 move synchronously. The circular pins 32 on the L-shaped plates 23 move from the separating section 3101 of the guiding channel rail 31 to the clamping section 3102 during the movement. And during the movement, through the guiding and limiting of the separating section 3101, the two L-shaped plates 23 approach each other along the inside of the movable groove 22, and drive the two clamping rollers 25 to approach and clamp on both sides of the water supply pipe synchronously. After the two clamping rollers 25 clamp the water supply pipe and continue to move with the movable frame 21, the ratchet 26 is pressed and limited by the elastic pressing piece 27, so as to limit the unidirectional rotation of the connecting shaft 24, so that the two clamping rollers 25 cannot rotate on the surface of the water supply pipe along the moving direction after clamping the water supply pipe. Thus, the water supply pipe approaches the branch direction of the water supply network under the clamping action of the two clamping rollers 25, and one end of the water supply pipe contacts one end of the branch of the water supply network, so that one end of the water supply pipe can be welded and fixed on the branch of the water supply network. When the welding and fixing are completed, the output shaft of the third motor 30 moves in the reverse direction, and the two clamping rollers 25 move in the reverse direction. When the two clamping rollers 25 move in the reverse direction, the corresponding connecting shaft 24 is driven to rotate in the reverse direction. The ratchet 26 on the connecting shaft 24 is no longer restricted by the elastic pressing piece 27 during the reverse rotation. Thus, when the clamping roller 25 moves in the reverse direction along the contact surface of the water supply pipe, it can rotate in cooperation along the surface of the water supply pipe through the contact friction force, so as to reduce the reverse pulling force on the water supply pipe when the clamping roller 25 moves in the reverse direction, reduce the influence of the reverse pulling force generated at the welding joint between the water supply pipe and the branch of the water supply network, and after the circular pin 32 moves back from the clamping section 3102 to the separating section 3101 inside, the two clamping rollers 25 move away from each other and release the contact with the surface of the water supply pipe, which is convenient to return to the initial position and perform the next docking of the water supply pipe.

[0042] As a further embodiment of the present invention, the pipeline conveying mechanism includes two inclined surface guiding blocks 33 (as Figure 10 shown), the two inclined surface guiding blocks 33 are fixedly connected to both sides inside the storage housing 1, arc-shaped grooves 34 are provided on one side of each of the two adjacent inclined surface guiding blocks 33, a strip-shaped groove 35 is provided at the bottom of the storage housing 1, and the bottom of the strip-shaped groove 35 is in through communication with the circular through-hole 8. A slider 36 is slidably connected to one end of the bottom of the storage housing 1 away from the support frame 2. A rectangular groove 37 is provided inside the slider 36. A connecting plate 38 is provided on the bottom surface inside the rectangular groove 37. Two limit pins 39 are slidably inserted into the connecting plate 38. The limit pins 39 are fixedly connected to the inside of the rectangular groove 37. The top of the connecting plate 38 is fixedly connected to a pushing bar 40. The top of the pushing bar 40 penetrates through the slider 36 and extends above the slider 36 and then is located inside the strip-shaped groove 35. A second hydraulic cylinder 41 is fixedly installed at the bottom of the slider 36. The piston rod of the second hydraulic cylinder 41 penetrates through the slider 36 and extends into the rectangular groove 37 and then is fixedly connected to the bottom of the connecting plate 38. A second lead screw 42 (as Figure 7 shown) is rotatably connected to the bottom of the storage housing 1. A second connecting ring 43 is fixedly connected to one side of the slider 36. The second connecting ring 43 is threadedly connected to the second lead screw 42. A fourth motor 44 is fixedly installed on the storage housing 1. The output shaft of the fourth motor 44 is fixedly connected to one end of the second lead screw 42. During operation, a plurality of water supply pipes are placed inside the storage housing 1, and through the inclined surface guiding at the top of the two inclined surface guiding blocks 33, the water supply pipes converge towards the middle and enter between the two arc-shaped grooves 34. The distance between the two arc-shaped grooves 34 is the same as the diameter of the circular through-hole 8. One end of the water supply pipe at the bottom between the two arc-shaped grooves 34 is directly opposite to the circular through-hole 8. The piston rod of the second hydraulic cylinder 41 moves upward, driving the connecting plate 38 to move upward along the sliding insertion part of the limit pins 39, so that the top of the pushing bar 40 moves upward along the strip-shaped groove 35 and is located at one end of the lowermost water supply pipe. The output shaft of the fourth motor 44 rotates to drive the second lead screw 42 to rotate. Through the threaded connection between the second lead screw 42 and the second connecting ring 43, the slider 36 moves towards the support frame 2 along the sliding connection at the bottom of the storage housing 1, and the lowermost water supply pipe between the two arc-shaped grooves 34 is pushed out along the circular through-hole 8. When the pushing bar 40 is located at the communication part of the circular through-hole 8 and the strip-shaped groove 35, the water supply pipe is completely pushed out of the storage housing 1. When the output shaft of the fourth motor 44 rotates in the reverse direction and drives the pushing bar 40 to return, the piston rod of the second hydraulic cylinder 41 moves in the reverse direction to drive the pushing bar 40 to move downward, preventing the pushing bar 40 from coming into contact and blocking with one end of the water supply pipe falling between the two arc-shaped grooves 34 during the return process, and ensuring the continuous pushing of the water supply pipe.

[0043] As a further embodiment of the present invention, circular grooves 45 are provided at the tops of both of the two inclined surface guiding blocks 33. A toggle roller 46 is arranged inside each circular groove 45. The top of the toggle roller 46 extends above the corresponding inclined surface guiding block 33. A fixed shaft 47 is fixedly connected inside the toggle roller 46. The fixed shaft 47 is rotatably connected inside the storage housing 1. Two fifth motors 48 (as Figure 9 shown) are fixedly installed at one end of the storage housing 1. The output shaft of the fifth motor 48 is fixedly connected to one end of the corresponding fixed shaft 47. During operation, when a large number of water supply pipes are arranged inside the storage housing 1 and are located at the tops of the two inclined surface guiding blocks 33, due to the large contact friction generated by the mutual contact between the water supply pipes, after the water supply pipes between the two arc-shaped grooves 34 are pushed out along the circular through-hole 8, the water supply pipes at the tops of the inclined surface guiding blocks 33 remain stationary due to the contact friction and it is difficult to enter between the two arc-shaped grooves 34. By rotating the output shafts of the two fifth motors 48 in the same direction, the corresponding fixed shafts 47 are driven to rotate, so that the toggle rollers 46 rotate in the corresponding circular grooves 45, and the tops of the toggle rollers 46 are used to make rotational contact with the water supply pipes at the tops of the inclined surface guiding blocks 33, so that the water supply pipes at the tops of the two inclined surface guiding blocks 33 are all conveyed in the same direction, enabling the plurality of water supply pipes to roll unidirectionally, so that the water supply pipes enter between the two arc-shaped grooves 34 during the movement, ensuring that the water supply pipes enter between the two arc-shaped grooves 34 and are continuously pushed.

[0044] A construction method for a water supply pipe network construction docking and pushing device, the method comprising the following steps:

[0045] Step 1: Place a plurality of water supply pipes for docking and fixing inside the storage housing 1, and drive the rollers 3 at the bottoms of the storage housing 1 and the support frame 2 to roll through the control handle 9, so that the storage housing 1 pushes the water supply pipes inside towards the docking position of the water supply pipe network;

[0046] Step 2: Through the action of the pipeline conveying mechanism, convey the water supply pipes inside the storage housing 1 upwards along the circular through-hole 8 to the upper part of the support frame 2. The water supply pipes move into the arc at the bottom of the arc-shaped placement block 7 in the middle section of the movable strip 6, and are limited through the action of the pipeline limiting mechanism. Then, through the action of the rotation adjustment mechanism, the rotating shaft 4 is rotated and adjusted, and the U-shaped strip 5 is driven to rotate synchronously, so as to adjust the flipping angle of the two arc-shaped placement blocks 7. Then, through the action of the displacement mechanism, adjust the distance between the U-shaped strip 5 and the movable strip 6, so that the two arc-shaped placement blocks 7 move towards the docking position of the water supply pipe network branch;

[0047] Step 3: Use the arc surface placement block 7 at one end of the bottom of the movable bar 6 to fit with the branch of the water supply network, and limit the arc surface placement block 7 at one end of the bottom of the movable bar 6 on the branch of the water supply network through the action of the pipeline limiting mechanism, so that the branch of the water supply network and the water supply pipeline installed in butt joint are coaxially arranged, and are respectively limited by the two arc surface placement blocks 7 to ensure that one end of the water supply pipeline and the branch of the water supply network can be accurately butted.

[0048] Working principle of the present invention:

[0049] Place a plurality of water supply pipelines for butt joint fixation inside the storage housing 1, and drive the rollers 3 at the bottom of the storage housing 1 and the support frame 2 to roll through the control handle 9, so that the storage housing 1 pushes the water supply pipelines inside it towards the butt joint position of the water supply network. After the storage housing 1 moves to one side of the water supply network, the water supply pipelines inside the storage housing 1 are transported along the circular through hole 8 above the support frame 2 through the action of the pipeline conveying mechanism. The water supply pipelines move into the arc surface at the bottom of the arc surface placement block 7 in the middle section of the movable bar 6 and are limited through the action of the pipeline limiting mechanism. Then, the rotating shaft 4 is rotationally adjusted through the action of the rotation adjustment mechanism, and the U-shaped bar 5 is driven to rotate synchronously, thereby adjusting the flipping angle of the two arc surface placement blocks 7. Then, the distance between the U-shaped bar 5 and the movable bar 6 is adjusted through the action of the displacement mechanism, so that the two arc surface placement blocks 7 move towards the butt joint position of the branch of the water supply network. Use the arc surface placement block 7 at one end of the bottom of the movable bar 6 to fit with the branch of the water supply network, and limit the arc surface placement block 7 at one end of the bottom of the movable bar 6 on the branch of the water supply network through the action of the pipeline limiting mechanism, so that the branch of the water supply network and the water supply pipeline installed in butt joint are coaxially arranged, and are respectively limited by the two arc surface placement blocks 7 to ensure that one end of the water supply pipeline and the branch of the water supply network can be accurately butted. And when one end of the water supply pipeline is fixedly butted on the branch of the water supply network, the water supply pipeline can be effectively supported and limited through the arc surface placement block 7, so that one end of the water supply pipeline can be stably welded on the branch of the water supply network, improving the butt joint efficiency of the water supply network and shortening the construction period.
