[0014] A construction method for a water supply network construction docking and pushing device, the method comprising the following steps:

[0015] Step 1: Place multiple water supply pipes for docking and fixing inside the material storage shell, and drive the rollers at the bottom of the material storage shell and the support frame to roll by controlling the handle, so that the material storage shell pushes the internal water supply pipes to the docking position of the water supply network;

[0017] Step three, use the arc-surface placement block at one end of the bottom of the movable bar to fit it with the branch of the water supply network, and use the pipe limiting mechanism to limit the arc-surface placement block at one end of the bottom of the movable bar on the branch of the water supply network, so that the branch of the water supply network and the docking water supply pipe are coaxially arranged, and the two arc-surface placement blocks are used to limit them respectively to ensure that one end of the water supply pipe and the branch of the water supply network can be accurately docked.

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

[0019] 1. The arc-surface placement block at one end of the bottom of the movable bar is limited 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 for docking are coaxially arranged, and the two arc-surface placement blocks are used to limit them respectively to ensure that one end of the water supply pipeline and the branch of the water supply network can be accurately docked, and when one end of the water supply pipeline is fixedly docked on the branch of the water supply network, the water supply pipeline can be effectively supported and limited by the arc-surface placement block, so that one end of the water supply pipeline can be stably welded on the branch of the water supply network, thereby improving the docking efficiency of the water supply network and shortening the construction period.

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

[0021] 3. When the two clamping rollers move in opposite directions, they drive the corresponding connecting shaft to rotate in opposite directions. The ratchet on the connecting shaft is no longer restricted by the rotation of the elastic plate when rotating in opposite directions. As a result, when the clamping rollers move in opposite directions along the contact surface of the water supply pipe, they can rotate along the surface of the water supply pipe through contact friction, thereby reducing the reverse pulling force on the water supply pipe when the clamping rollers move in opposite directions, and reducing the reverse pulling force generated at the welding point of the water supply pipe and the water supply network branch. After the circular pin moves back from the clamping section to the inside of the separation section, the two clamping rollers move away from each other and release the contact with the surface of the water supply pipe, so as to return to the initial position and carry out the next pipe docking.

[0022] 4. When the push bar is located at the connection point between the circular through hole and the strip groove, the water supply pipe is completely pushed out of the material storage shell, and when the output shaft of the fourth motor rotates in the opposite direction and drives the push bar to return, the piston shaft of the second hydraulic cylinder moves in the opposite direction to drive the push bar to move downward, preventing the push bar from contacting and blocking one end of the water supply pipe falling between the two arc grooves during the return process, thereby 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] The middle section of the bottom of the movable bar 6 and the end away from the material storage shell 1 are fixedly connected with an arc-surface placement block 7, and the arc-surface placement block 7 is connected with a pipeline limiting mechanism. A circular through hole 8 is opened on the side of the material storage shell 1 close to the supporting frame 2, and the arc surfaces of the two arc-surface placement blocks 7 are coaxially arranged with the circular through hole 8. A pipeline conveying mechanism is connected to the material storage shell 1, and a handle 9 is fixedly connected to the end of the supporting frame 2 away from the material storage shell 1. When working, the prior art usually needs to transport the water supply pipeline to the docking area and then carry out docking installation when docking the water supply pipeline. It is difficult to accurately dock the water supply pipeline 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. During the fixing and sealing process, it is difficult to effectively support and limit the water supply pipe in the docking, thereby reducing the docking efficiency of the water supply network and extending the construction period of the water supply network. The technical solution can solve the above problems. The specific working method is as follows: a plurality of water supply pipes for docking and fixing are placed inside the storage shell 1, and the storage shell 1 and the rollers 3 at the bottom of the support frame 2 are driven to roll by controlling the handle 9, so that the storage shell 1 pushes the internal water supply pipe to the docking position of the water supply network. After the storage shell 1 moves to one side of the water supply network, the water supply pipe is pushed through the pipe. The conveying mechanism conveys the water supply pipe inside the storage shell 1 along the circular through hole 8 to the top of the support frame 2, and the water supply pipe moves to the arc surface at the bottom of the arc surface placement block 7 in the middle section of the movable bar 6, and is limited by the action of the pipe limiting mechanism, and then the rotating shaft 4 is rotated and adjusted by 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 surface placement blocks 7, and then the distance between the U-shaped bar 5 and the movable bar 6 is adjusted by the action of the displacement mechanism, so that the two arc surface placement blocks 7 are moved to the docking position of the water supply pipe network branch, and the arc surface placement block 7 at one end of the bottom of the movable bar 6 is used to connect with the water supply pipe network branch. The branch of the pipe network is fitted, and the arc-surface placement block 7 at one end of the bottom of the movable bar 6 is limited on the branch of the water supply pipe network through the action of the pipe limiting mechanism, so that the branch of the water supply pipe network and the docked water supply pipe are coaxially arranged, and are limited respectively by two arc-surface placement blocks 7 to ensure that one end of the water supply pipe and the branch of the water supply pipe network can be accurately docked, and when one end of the water supply pipe is fixedly docked on the branch of the water supply pipe network, the water supply pipe can be effectively supported and limited by the arc-surface placement block 7, so that one end of the water supply pipe can be stably welded on the branch of the water supply pipe network, thereby improving the docking efficiency of the water supply pipe network and shortening the construction period.

[0038] As a further implementation scheme of the present invention, the rotation adjustment mechanism includes a matching gear 10 and a first motor 11, the matching gear 10 is fixedly connected to the rotating shaft 4, the first motor 11 is fixedly installed on the material storage shell 1, and a driving gear 12 is fixedly connected to the output shaft of the first motor 11, and the driving gear 12 is meshed with the matching gear 10; when working, the driving gear 12 is driven to rotate synchronously by the rotation of the output shaft of the first motor 11, and the meshing action of the driving gear 12 and the matching gear 10 makes the rotating shaft 4 rotate along the rotating connection of the material storage shell 1, and drives the U-shaped bar 5 and the movable bar 6 to rotate synchronously, thereby adjusting the angle between the arc surface placement block 7 and the water supply network branch, so that the arc surface at the bottom of the arc surface placement block 7 can face the water supply network branch, which is convenient for the arc surface placement block 7 at one end of the bottom of the movable bar 6 to limit the water supply network branch.

[0039] As a further implementation scheme of the present invention, the displacement mechanism includes two sliding bars 13, both of which are fixedly connected to the top of the movable bar 6 and slidably inserted on the U-shaped bar 5. Two first hydraulic cylinders 14 are fixedly installed inside the U-shaped bar 5. The piston shafts of the first hydraulic cylinders 14 penetrate the U-shaped bar 5 and extend to the bottom of the U-shaped bar 5 and are fixedly connected to the top of the movable bar 6. When working, after the arc surface of the bottom of the arc surface placement block 7 faces the branch of the water supply network through the action of the rotating adjustment mechanism, the piston shafts of the two first hydraulic cylinders 14 move synchronously and drive the movable bar 6 away from the U-shaped bar 5, so that the arc surface placement block 7 on the movable bar 6 Move synchronously and approach the branch of the water supply network, the sliding bar 13 on the movable bar 6 moves along the sliding joint of the U-shaped bar 5 and limits the movement of the movable bar 6. When the arc placement block 7 at one end of the bottom of the movable bar 6 contacts the branch of the water supply network, the branch of the water supply network is limited in the arc surface at the bottom of the corresponding arc placement block 7 through the action of the pipeline limiting mechanism, so that the clamped and limited water supply pipe on the arc placement block 7 in the middle section of the bottom of the movable bar 6 and the branch of the water supply network are coaxially arranged, so that when the water supply pipe and the branch of the water supply network are welded and fixed, the water supply pipe and one end of the branch of the water supply network are always kept docked and supported and limited.

[0040] As a further implementation scheme of the present invention, the pipeline limiting mechanism includes two mounting frames 15, the two mounting frames 15 are fixedly connected to the two sides of the arc surface placement block 7, the interior of the mounting frames 15 is slidably connected with a movable plate 16, the movable plate 16 is fixedly connected with an arc surface limiting strip 17, the two arc surface limiting strips 17 are both located at the bottom of the arc surface placement block 7, the arc surface limiting strip 17 corresponds to the arc surface of the arc surface placement block 7, a bidirectional lead screw 18 is rotatably connected between the two mounting frames 15, the two 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; when working, the bidirectional lead screw 18 is driven to rotate by the rotation of the output shaft of the second motor 19, and the bidirectional lead screw 18 is driven to rotate by the rotation of the output shaft of the second motor 19. Through the threaded connection between the bidirectional lead screw 18 and the two movable plates 16, the two movable plates 16 are moved along the corresponding mounting frame 15 through the rotation of the bidirectional lead screw 18, so that the two movable plates 16 are close to each other. When the two movable plates 16 are close to each other, the corresponding arc surface limit strips 17 are driven to move synchronously, so that the two arc surface limit strips 17 are close to each other, and the arc surface on the arc surface limit strip 17 fits with the surface of the water supply pipe, so that the water supply pipe is limited in the arc surface at the bottom of the arc surface placement block 7. When the output shaft of the second motor 19 rotates in the opposite direction, the two arc surface limit strips 17 move away from each other, thereby releasing the limitation of the water supply pipe in the arc surface at the bottom of the arc surface placement block 7, so that the two arc surface placement blocks 7 can limit and release the water supply network branch and the water supply pipe respectively.

[0041] As a further embodiment of the present invention, a mounting groove 20 is provided at the bottom of the movable bar 6, a movable frame 21 is slidably connected inside the mounting groove 20, a movable groove 22 is provided on the movable frame 21, both sides of the movable groove 22 are slidably connected to L-shaped plates 23, the bottoms of the two L-shaped plates 23 are rotatably connected to connecting shafts 24, the connecting shafts 24 are fixedly connected to clamping rollers 25, and the tops of the connecting shafts 24 are fixedly connected to ratchet wheels 26 (such as Figure 2 As shown in the figure, the L-shaped plate 23 is fixedly connected with an elastic piece 27, one end of the elastic piece 27 is respectively located on the side of the corresponding ratchet 26, the movable frame 21 is fixedly inserted with a first connecting ring 28, the interior of the mounting groove 20 is rotatably connected with a first lead screw 29, and the first lead screw 29 is threadedly connected to the interior of the first connecting ring 28, and one end of the movable bar 6 is fixedly installed with a third motor 30 (as shown in the figure). Figure 3As shown in the figure, the output shaft of the third motor 30 is fixedly connected to one end of the first lead screw 29, and two guide grooves 31 are fixedly connected to the top surface inside the mounting groove 20, and the guide groove 31 includes a separation section 3101 and a clamping section 3102. The adjacent sides of the two L-shaped plates 23 are fixedly connected with circular pins 32, and one end of the circular pins 32 is respectively located inside the corresponding guide grooves 31, and the movable frame 21 is located between the circular through hole 8 and the arc surface placement block 7 in the middle section of the movable bar 6; when working, when the water supply pipe moves along the circular through hole 8 to the arc surface at the bottom of the arc surface placement block 7 in the middle section of the movable bar 6, the water supply pipe is limited by the corresponding arc surface limiting strip 17, and the arc surface placement block 7 at one end of the movable bar 6 passes through the corresponding arc When the surface limit strip 17 is limited on the branch of the water supply network, the connection between the branch of the water supply network and the water supply pipeline is completed, and the first lead screw 29 is driven to rotate unidirectionally through the output shaft of the third motor 30, and the first lead screw 29 and the first connecting ring 28 are threadedly connected to each other, so that 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, and the circular pin 32 on the L-shaped plate 23 moves from the separation section 3101 of the guide groove rail 31 to the clamping section 3102 during the movement, and the two L-shaped plates 23 are guided and limited by the separation section 3101 during the movement, so that the two L-shaped plates 23 are close to each other along the inside of the movable groove 22, and drive the two clamping sections 3102 to move synchronously. The holding rollers 25 synchronously approach and clamp the two sides of the water supply pipe. After the two clamping rollers 25 clamp the water supply pipe, they continue to move with the movable frame 21, and the ratchet 26 is pressed and limited by the elastic stopper 27, thereby limiting 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. Therefore, the water supply pipe is clamped by the two clamping rollers 25. The water supply pipe is close to the branch direction of the water supply network, and one end of the water supply pipe is in contact with one end of the branch of the water supply network, so that one end of the water supply pipe can be welded and fixed to the branch of the water supply network. After the welding and fixing is completed, the output shaft of the third motor 30 moves in the opposite direction, and the two clamping rollers 25 move in the opposite direction. When the two clamping rollers 25 move in opposite directions, they drive the corresponding connecting shaft 24 to rotate in opposite directions. The ratchet 26 on the connecting shaft 24 is no longer restricted by the rotation of the elastic stop 27 when rotating in opposite directions. As a result, when the clamping rollers 25 move in opposite directions along the contact surface of the water supply pipe, they can rotate along the surface of the water supply pipe through contact friction, thereby reducing the reverse pulling force on the water supply pipe when the clamping rollers 25 move in opposite directions, and reducing the reverse pulling force generated at the welding point of the water supply pipe and the water supply network branch. After the circular pin 32 moves back from the clamping section 3102 to the inside of the separation section 3101, the two clamping rollers 25 move away from each other and release the contact with the surface of the water supply pipe, so as to return to the initial position and carry out the next water supply pipe docking.

Figure 7 As shown), a second connecting ring 43 is fixedly connected to one side of the slider 36, and the second connecting ring 43 is threadedly connected to the second lead screw 42. A fourth motor 44 is fixedly installed on the material storage shell 1, and the output shaft of the fourth motor 44 is fixedly connected to one end of the second lead screw 42; when working, multiple water supply pipes are placed inside the material storage shell 1, and are guided by the inclined surfaces at the top of the two inclined guide blocks 33 to make the water supply pipes converge to the middle and enter between the two arc grooves 34. The distance between the two arc grooves 34 is the same as the diameter of the circular through hole 8. One end of the water supply pipe located at the bottom between the two arc grooves 34 faces the circular through hole 8, and moves upward through the piston axis of the second hydraulic cylinder 41, and drives the connecting plate 38 to move upward along the sliding insertion of the limit pin 39, so that the top end of the push bar 40 moves upward along the strip groove 35 and At one end of the water supply pipe at the bottom, the second lead screw 42 is driven to rotate by the output shaft of the fourth motor 44, and the slider 36 is moved toward the support frame 2 along the sliding connection at the bottom of the storage shell 1 through the threaded connection between the second lead screw 42 and the second connecting ring 43, and the water supply pipe at the bottom between the two arc grooves 34 is pushed out along the circular through hole 8. When the push bar 40 is located at the connection between the circular through hole 8 and the strip groove 35, the water supply pipe is completely pushed out of the storage shell 1, and when the output shaft of the fourth motor 44 rotates in the opposite direction and drives the push bar 40 to return, the push bar 40 is driven downward by the reverse movement of the piston shaft of the second hydraulic cylinder 41, so as to prevent the push bar 40 from contacting and blocking the end of the water supply pipe falling between the two arc grooves 34 during the return process, thereby ensuring the continuous pushing of the water supply pipe.

[0043] As a further embodiment of the present invention, the tops of the two inclined guide blocks 33 are each provided with a circular groove 45, and the inside of the circular groove 45 is provided with a toggle roller 46, and the top of the toggle roller 46 extends above the corresponding inclined guide block 33, and the inside of the toggle roller 46 is fixedly connected with a fixed shaft 47, and the fixed shaft 47 is rotatably connected to the inside of the storage housing 1, and one end of the storage housing 1 is fixedly installed with two fifth motors 48 (such as Fig. 9 As shown), 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 material storage shell 1 and are located at the tops of the two inclined guide blocks 33, due to the mutual contact between the water supply pipes, a large contact friction force is generated, resulting in the water supply pipe between the two arc grooves 34 being pushed out along the circular through hole 8. The water supply pipe on the top of the inclined guide block 33 remains stationary due to the contact friction force, and it is difficult to enter between the two arc grooves 34. The output shafts of the two fifth motors 48 rotate in the same direction, driving the corresponding fixed shaft 47 to rotate, so that the toggle roller 46 rotates in the corresponding circular groove 45, and the top of the toggle roller 46 is used to rotate and contact with the water supply pipe on the top of the inclined guide block 33, so that the water supply pipes on the top of the two inclined guide blocks 33 are all transported in the same direction, so that multiple water supply pipes are unidirectionally rolled, so that the water supply pipe enters between the two arc grooves 34 during the movement, ensuring that the water supply pipe enters between the two arc grooves 34 and is continuously pushed.

[0045] Step 1: Place multiple water supply pipes for docking and fixing inside the material storage shell 1, and drive the rollers 3 at the bottom of the material storage shell 1 and the support frame 2 to roll by controlling the handle 9, so that the material storage shell 1 pushes the internal water supply pipes to the docking position of the water supply network;

[0046] Step 2: The water supply pipe inside the material storage shell 1 is transported along the circular through hole 8 to the top of the support frame 2 through the action of the pipe conveying mechanism, and the water supply pipe is moved to the arc surface at the bottom of the arc surface placement block 7 in the middle section of the movable bar 6, and is limited by the action of the pipe limiting mechanism, and 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 surface placement blocks 7, and 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 are moved to the docking position of the water supply network branch;

[0047] Step three, 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 docking water supply pipeline are coaxially arranged, and the two arc-surface placement blocks 7 are used to limit them respectively to ensure that one end of the water supply pipeline and the branch of the water supply network can be accurately docked.
