Description

Technical Field

[0001] This invention relates to the field of drainage pipe laying technology, specifically to a drainage pipe laying device and method for houses. Background Technology

[0002] During the construction of a house, drainage pipes need to be laid indoors and outdoors for drainage, depending on the house's condition. In practice, adjacent drainage pipes are often connected. At this time, the two drainage pipes need to be aligned. In order to reduce the workload of workers in the process of connecting drainage pipes, pipe laying devices are often used to assist in the pipe laying.

[0003] A Chinese patent with publication number CN109252579B discloses a drainage pipe laying device for building drainage projects, including a counterweight base, a turning mechanism, a lifting mechanism, and a clamping mechanism. The turning mechanism is located above the counterweight base, the lifting mechanism is located above the turning mechanism, and the clamping mechanism is located on one side of the lifting mechanism. Casters are fixedly connected to the four corners of the bottom of the counterweight base. This invention can clamp and lock the drainage pipe by setting the clamping mechanism and the locking mechanism, allowing construction workers to work with both hands, greatly improving work efficiency. Furthermore, the turning mechanism and the lifting mechanism can adjust the position of the drainage pipe at multiple angles, making the laying position of the drainage pipe more precise and greatly reducing the possibility of water leakage. At the same time, this invention is applicable to drainage pipes of different diameters and placement trenches of different depths, enhancing the applicability of the device.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In actual operation, multiple drain pipes are usually stacked horizontally on the ground. Therefore, when using the laying device, the workers need to lift one drain pipe first, then adjust the angle of the drain pipe to make it vertical, and then use the clamping mechanism to clamp and fix the drain pipe. Due to the long size and large volume of the drain pipe, it is inconvenient for the workers to operate.

[0005] Therefore, we propose a drainage pipe laying device and method for houses. Summary of the Invention

[0006] The purpose of this invention is to provide a drainage pipe laying device and method for houses to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drainage pipe laying device and method for a building, comprising a chassis and a drainage pipe, wherein a column is fixedly installed on the upper surface of the chassis, a rotating shaft is rotatably connected to the upper end of the column, an mounting plate is fixedly connected to the end of the rotating shaft away from the column, a fixing plate is fixedly installed on the surface of the mounting plate, and an electric telescopic rod is fixedly installed on both sides of the chassis, the output end of the electric telescopic rod is fixedly connected to a support plate, and the device further comprises: a lifting structure respectively disposed on the surface of the mounting plate for lifting the drainage pipe, wherein the lifting structure... The structure includes a roller rotatably connected to the mounting plate, straps for binding the drain pipe, clamps for holding the drain pipe, and baffles for limiting the position of the drain pipe; an adjustment structure for adjusting the angle of the drain pipe, respectively disposed on the side wall of the column, the adjustment structure including two brackets fixedly connected to the column, a rack and a gear ring for driving the rotating shaft to rotate, and a lead screw for driving the rack to move; and a counterweight structure disposed on the surface of the chassis to prevent the chassis from tilting as much as possible, the counterweight structure including a base fixedly connected to the chassis and several counterweight blocks for increasing the weight.

[0008] The aforementioned components achieve the following effects: By setting up a lifting structure, it is convenient for workers to lift and suspend the drainage pipe during installation, thus facilitating subsequent operations. By setting up an adjustment structure, the drainage pipe can be adjusted to the required angle, and after adjustment, the position of the drainage pipe can be automatically restricted, further facilitating the laying of the drainage pipe. By setting up a counterweight structure, the center of gravity of the pipe laying device is lowered by the counterweight blocks, which minimizes the possibility of the chassis tilting, thereby improving the stability of the pipe laying device. Furthermore, the number of counterweight blocks can be adjusted according to actual needs.

[0009] Preferably, the straps are wound around the arc surface of the reel. Two rectangular holes are formed on the surface of the fixing plate. A directional roller is rotatably connected to the inner wall of each rectangular hole. The straps pass through the directional rollers. The baffle is fixedly connected to the fixing plate. A servo motor is fixedly mounted on the surface of the fixing plate. The output end of the servo motor is fixedly connected to the reel. Support rods are fixedly connected to the ends of the two straps away from the reel. Two support frames are fixedly connected to the arc surface of each support rod. Two oblique holes are formed on the surface of each support frame. A sliding rod is slidably connected to the inner wall of each oblique hole. The arc surface of the sliding rod... The surface is fixedly connected to the clamping plate. The lower end of the clamping plate has an arc structure. A threaded post is threaded into the surface of the clamping plate. One end of the threaded post is rotatably connected to a positioning plate. The positioning plate is slidably connected to the clamping plate. A round rod is fixedly connected inside the oblique hole. The round rod passes through the slide rod. A round plate is fixedly connected to the arc surface of the roller. An electric actuator is fixedly connected to the mounting plate relative to the round plate. A push plate is fixedly connected to the output end of the electric actuator. The vertical cross-section of the baffle is "V" shaped. The side of the baffle away from the fixed plate has an arc structure. The clamping plate is slidably connected to the drain pipe.

[0010] The aforementioned components achieve the following effects: Moving the support frame downwards causes the sliding rod to move, which in turn moves the clamping plate. When the lower end of the clamping plate abuts against the arc surface of the drain pipe, pressing the support frame further compresses the clamping plate. Because the contact point between the clamping plate and the drain pipe is arc-shaped, the arc surface of the drain pipe can squeeze the clamping plate, causing the two clamping plates to slide away from each other, thus facilitating operation. At this point, the two clamping plates will cause the sliding rod to slide away from each other along the inner wall of the inclined hole. The round rod restricts the sliding path of the sliding rod. Continuing to slide the support frame will cause the sliding rod to slide downwards along the inner wall of the inclined hole. When the sliding rod reaches the bottom of the inner wall of the inclined hole, rotating the threaded column will cause the threaded column to drive the positioning plate to slide along the surface of the clamping plate. The clamping plate prevents the positioning plate from rotating with the threaded column. The sliding positioning plate will then contact the drain pipe. The two positioning plates achieve the function of controlling the drainage... The clamps further restrict the position of the drain pipe, holding it in place. Then, the servo motor is activated, its output rotating to drive the reel. This reel winds up the strap, which slides along the adjusting roller. The adjusting roller, due to the strap's pressure, rotates along the inner wall of the rectangular hole, adjusting the angle of the strap as it passes, reducing wear and extending its lifespan. The sliding strap lifts the support rod, which moves the support frame. The sliding rod, with the support frame's help, moves the clamps, which in turn move the drain pipe. During this process, because the sliding rod is located at the bottom of the inclined hole's inner wall, the two clamps, under the influence of the drain pipe's weight, do not slide away from each other, thus achieving the purpose of clamping and lifting the drain pipe. Furthermore, lifting the drain pipe does not require manual lifting, making operation more convenient.

[0011] Preferably, a square plate is fixedly connected to one end of the slide rod, and a first spring is fixedly connected between the two square plates.

[0012] The effect achieved by the above components is that the two clamping plates slide towards each other under the action of the first spring tension, and the first spring accelerates the automatic reset of the two clamping plates.

[0013] Preferably, a synchronizing rod slides through the square plate, with both ends of the synchronizing rod abutting against the inner wall of the support frame, and the first spring is sleeved on the arc surface of the synchronizing rod.

[0014] The effect achieved by the above components is that the sliding of the square plate will drive the synchronizing rod to slide along the inner wall of the support frame. The synchronizing rod ensures that the two square plates slide synchronously, thereby limiting the sliding path of the two clamping plates.

[0015] Preferably, a lead screw is rotatably connected within the two brackets. The arc surface of the lead screw is threadedly connected to the rack. The gear ring is fixedly sleeved on the arc surface of the rotating shaft. The tooth surface of the gear ring meshes with the tooth surface of the rack. Hexagonal blocks are fixedly connected to both ends of the lead screw. Two U-shaped plates are sleeved on the arc surface of the lead screw. A cross plate is fixedly connected to the surface of the U-shaped plate. A rotating ring is fixedly connected to the surface of the cross plate. An insertion hole is opened on the surface of the cross plate. The size of the insertion hole on the cross plate is adapted to the size of the hexagonal block.

[0016] The above components achieve the following effect: when the rotating ring is rotated, the cross plate rotates, which in turn drives the hexagonal block to rotate. The rotation of the hexagonal block drives the lead screw to rotate. At this time, the lead screw drives the rack to move through the thread. The movement of the rack drives the gear ring to rotate. The rotation of the gear ring drives the rotating shaft to rotate. The mounting plate rotates through the rotating shaft, which drives the fixing plate to rotate. The fixing plate and the baffle cooperate to drive the drain pipe to rotate, thereby adjusting the angle of the drain pipe and facilitating the subsequent installation of the drain pipe.

[0017] Preferably, a second spring is fitted onto the arc surface of the lead screw, one end of the second spring is fixedly connected to the lead screw, and the other end of the second spring is fixedly connected to a top ring. The top ring is slidably fitted onto the arc surface of the lead screw, and the top ring is slidably connected to a U-shaped plate.

[0018] The effect achieved by the above components is as follows: when the second spring extends, the top ring will move towards the hexagonal block with the help of the tension of the second spring. The movement of the top ring will squeeze the U-shaped plate. The second spring and the top ring work together to make the U-shaped plate automatically reset.

[0019] Preferably, a reset plate is fixedly connected to the arc surface of the rotating shaft, and a rotating plate is fixedly connected to the upper end of the column.

[0020] The effect achieved by the above components is as follows: the rotating shaft will drive the reset plate to rotate. When the reset plate comes into contact with the rotating plate, the rotating plate will prevent the reset plate from continuing to rotate, thereby limiting the position of the rotating shaft and thus returning the mounting plate to a horizontal state.

[0021] Preferably, a strip plate is rotatably connected to the inner wall of the base, and a counterweight is slidably fitted onto the surface of the strip plate. The counterweight is made of stainless steel. A rectangular tube is slidably fitted onto the surface of the strip plate. A screw is threaded into the side wall of the rectangular tube. The screw passes through the rectangular tube and abuts against the surface of the strip plate. A hanging rope is fixedly connected to the side wall of the rectangular tube. A hook is fixedly connected to the side of the column near the hanging rope. The hanging rope is fitted onto the arc surface of the hook.

[0022] The aforementioned components achieve the following effects: When it is necessary to minimize chassis tilting, the hanging rope is removed from the arc surface of the hook, and then the strip plate is rotated along the inner wall of the base. When the strip plate contacts the bottom of the inner wall of the base, the base will prevent the strip plate from continuing to rotate. Then, the counterweight block is slid along the surface of the strip plate towards the rectangular tube. When the screw abuts against the surface of the strip plate, the counterweight block lowers the center of gravity of the pipe-laying device, minimizing chassis tilting and thus improving the stability of the pipe-laying device. When the number of counterweight blocks needs to be adjusted, the screw is rotated, and the screw will disengage from the strip plate through threaded movement. Then, the rectangular tube can be removed from the surface of the strip plate, and the number of counterweight blocks can be increased or decreased. After adjustment, the rectangular tube is put back onto the surface of the strip plate, and the screw is rotated in the opposite direction. When the screw abuts against the surface of the strip plate, the screw restricts the position of the rectangular tube, thus preventing the counterweight block from falling off the surface of the strip plate.

[0023] Preferably, a support plate is fixedly connected to the surface of the chassis, and a buffer strip is fixedly connected to the upper surface of the support plate. The buffer strip is made of rubber and is located below the counterweight.

[0024] The effect achieved by the above components is as follows: the counterweight will slide down the surface of the strip plate under its own weight, and the bottom counterweight will come into contact with the rubber buffer strip. The buffer strip will be compressed and deformed to cushion the counterweight, thereby preventing the counterweight from damaging the base as much as possible.

[0025] Preferably, a method for laying a building drainage pipe includes the following processing steps:

[0026] S1. Adjust the center of gravity of the pipe laying device with the aid of counterweights according to the size and weight of the drainage pipe;

[0027] S2. Use clamps to hold the drain pipe;

[0028] S3. Start the servo motor and use the reel to wind up the straps, thereby lifting the drain pipe;

[0029] S4. Rotate the rotating ring to adjust the drain pipe to the required angle using the screw, rack, and gear ring.

[0030] S5. Use the electric telescopic rod and support plate to fine-tune the height of the drain pipe so that it is aligned with other drain pipes.

[0031] S6. Connect and install the drain pipe with other drain pipes.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. This invention, by setting up a lifting structure, can clamp drainage pipes of different diameters with the help of clamping plates, and then use a servo motor to lift the drainage pipe upwards. Then, with the cooperation of baffles, the position of the drainage pipe is restricted, thereby making it convenient for workers to lift and suspend the drainage pipe during the installation process, thus facilitating subsequent operations.

[0034] 2. This invention, by setting an adjustment structure, can adjust the drainage pipe to the required angle by means of a lead screw, rack and pinion, and toothed ring. After adjustment, it can also automatically restrict the position of the drainage pipe, thereby further facilitating the laying of drainage pipes by workers.

[0035] 3. By setting up a counterweight structure, the present invention lowers the center of gravity of the pipe-laying device with the help of counterweight blocks, thereby preventing the chassis from tilting and improving the stability of the pipe-laying device. In addition, the number of counterweight blocks can be adjusted according to actual needs. Attached Figure Description

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figure 1-12This invention provides a technical solution: a drainage pipe laying device and method for a building, including a chassis 1 and a drainage pipe 11. A column 2 is fixedly installed on the upper surface of the chassis 1. A rotating shaft 3 is rotatably connected to the upper end of the column 2. An installation plate 4 is fixedly connected to the end of the rotating shaft 3 away from the column 2. A fixing plate 5 is fixedly installed on the surface of the installation plate 4. Electric telescopic rods 9 are fixedly installed on both sides of the chassis 1. A support plate 10 is fixedly connected to the output end of the electric telescopic rods 9. The invention also includes: a lifting structure 6 respectively disposed on the surface of the installation plate 4 for lifting the drainage pipe 11. The lifting structure 6 includes a roller 601 rotatably connected to the installation plate 4 and a mechanism for binding... The drain pipe 11 is secured by a strap 602, a clamping plate 613 for holding the drain pipe 11, and a baffle 620 for limiting the position of the drain pipe 11. An adjustment structure 7 is set on the side wall of the column 2 to adjust the angle of the drain pipe 11. The adjustment structure 7 includes two brackets 701 fixedly connected to the column 2, a rack 707 and a gear ring 708 for driving the rotating shaft 3 to rotate, and a lead screw 702 for driving the rack 707 to move. A counterweight structure 8 is set on the surface of the chassis 1 to prevent the chassis 1 from tilting as much as possible. The counterweight structure 8 includes a base 81 fixedly connected to the chassis 1 and several counterweight blocks 83 for increasing the weight.

[0051] The following section will explain the specific configuration and function of its lifting structure 6, adjusting structure 7, and counterweight structure 8.

[0052] Reference Figures 2-5 as well as Figure 11 , Figure 12As shown in this embodiment: the strap 602 is wound around the arc surface of the reel 601. Two rectangular holes 603 are formed on the surface of the fixing plate 5. A directional roller 604 is rotatably connected to the inner wall of the rectangular holes 603. The strap 602 passes through the directional roller 604. The baffle 620 is fixedly connected to the fixing plate 5. A servo motor 605 is fixedly mounted on the surface of the fixing plate 5. The output end of the servo motor 605 is fixedly connected to the reel 601. A support rod 606 is fixedly connected to the end of each strap 602 away from the reel 601. Two support frames 607 are fixedly connected to the arc surface of the support rod 606. Two oblique holes 611 are formed on the surface of the support frames 607. A sliding rod 612 is slidably connected to the inner wall of the oblique holes 611. The arc surface of the sliding rod 612 is fixedly connected to the clamping plate 613. The lower end of the clamping plate 613 has an arc structure. A threaded post 614 is threaded into the surface of the clamping plate 613. One end of the threaded post 614 is rotatably connected to a positioning plate 615. The positioning plate 615 is slidably connected to the clamping plate 613. A round rod 618 is fixedly connected in the inclined hole 611. The round rod 618 passes through the slide rod 612. A round plate 608 is fixedly connected to the arc surface of the roller 601. An electric actuator 609 is fixedly connected to the mounting plate 4 relative to the round plate 608. A push plate 610 is fixedly connected to the output end of the electric actuator 609. The vertical section of the baffle 620 is "V" shaped. The side of the baffle 620 away from the fixed plate 5 has an arc structure. The clamping plate 613 is slidably connected to the drain pipe 11. The support frame 607 moves downward. The movement of the support frame 607 will drive the slide rod 612. The movement of the sliding rod 612 causes the clamping plate 613 to move. When the lower end of the clamping plate 613 abuts against the arc surface of the drain pipe 11, the support frame 607 continues to press down. Because the contact point between the clamping plate 613 and the drain pipe 11 is an arc structure, the arc surface of the drain pipe 11 can squeeze the clamping plate 613, causing the two clamping plates 613 to slide away from each other, thus facilitating operation. At this time, the two clamping plates 613 will cause the sliding rod 612 to slide away from each other along the inner wall of the inclined hole 611. The round rod 618 achieves the function of restricting the sliding path of the sliding rod 612. Continuing to slide the support frame 607 will cause the sliding rod 612 to slide downward along the inner wall of the inclined hole 611. When the sliding rod 612 slides to the bottom of the inner wall of the inclined hole 611, the threaded column 614 is rotated. 614 uses threads to drive the positioning plate 615 to slide along the surface of the clamping plate 613. The clamping plate 613 prevents the positioning plate 615 from rotating with the threaded post 614. The sliding positioning plate 615 will contact the drain pipe 11. The two positioning plates 615 further restrict the position of the drain pipe 11, and the clamping plate 613 clamps the drain pipe 11. Then, the servo motor 605 is started. The output end of the servo motor 605 rotates, which drives the reel 601 to rotate. The rotation of the reel 601 will wind up the binding strap 602. At this time, the binding strap 602 will slide along the adjusting roller 604. The adjusting roller 604 will rotate along the inner wall of the rectangular hole 603 due to the compression of the binding strap 602, thereby adjusting the angle of the binding strap 602 as it passes through the adjusting roller 604.To reduce wear on the strap 602 and extend its service life, the strap 602 slides, lifting the support rod 606. The support rod 606 then moves the support frame 607. The sliding rod 612, with the help of the support frame 607, moves the clamping plate 613, which in turn moves the drain pipe 11. During this process, because the sliding rod 612 is located at the bottom of the inner wall of the inclined hole 611, the two clamping plates 613 will not slide away from each other due to the gravity of the drain pipe 11. This achieves the purpose of clamping and lifting the drain pipe 11, and it eliminates the need for manual lifting of the drain pipe 11, making operation more convenient. A square plate 616 is fixedly connected to one end of the sliding rod 612, and a first spring 617 is fixedly connected between the two square plates 616. Under the tension of the first spring 617, the two clamping plates 613 slide towards each other, accelerating the automatic reset of the two clamping plates 613. A synchronizing rod 619 slides through the square plate 616. Both ends of the synchronizing rod 619 abut against the inner wall of the support frame 607. A first spring 617 is sleeved on the arc surface of the synchronizing rod 619. Sliding of the square plate 616 causes the synchronizing rod 619 to slide along the inner wall of the support frame 607. The synchronizing rod 619 ensures that the two square plates 616 slide synchronously, thereby limiting the sliding path of the two clamping plates 613.

[0053] Reference Figure 2 and Figures 6-8As shown, specifically, a lead screw 702 is rotatably connected within the two supports 701. The arc surface of the lead screw 702 is threadedly connected to the rack 707. A gear ring 708 is fixedly sleeved on the arc surface of the rotating shaft 3, and the tooth surface of the gear ring 708 meshes with the tooth surface of the rack 707. Hexagonal blocks 706 are fixedly connected to both ends of the lead screw 702. Two U-shaped plates 703 are sleeved on the arc surface of the lead screw 702. A cross plate 704 is fixedly connected to the surface of the U-shaped plate 703. A rotating ring 705 is fixedly connected to the surface of the cross plate 704. An insertion hole is opened on the surface of the cross plate 704. The size of the insertion hole on the cross plate 704 is... The hexagonal block 706 is sized to match the rotation of the rotating ring 705. The rotation of the cross plate 704 via the rotating ring 705 will drive the hexagonal block 706 to rotate. The rotation of the hexagonal block 706 will drive the lead screw 702 to rotate. At this time, the lead screw 702 will drive the rack 707 to move via the thread. The movement of the rack 707 will drive the gear ring 708 to rotate. The rotation of the gear ring 708 will drive the rotating shaft 3 to rotate. The mounting plate 4 will drive the fixing plate 5 to rotate via the rotating shaft 3. The fixing plate 5 and the baffle 620 will drive the drain pipe 11 to rotate, thereby adjusting the angle of the drain pipe 11 and facilitating the subsequent installation of the drain pipe 11. A second spring 709 is fitted onto the arc surface of the lead screw 702. One end of the second spring 709 is fixedly connected to the lead screw 702, and the other end is fixedly connected to a top ring 710. The top ring 710 slides on the arc surface of the lead screw 702 and is slidably connected to the U-shaped plate 703. When the second spring 709 extends, the top ring 710 moves towards the hexagonal block 706 under the tension of the second spring 709. The movement of the top ring 710 compresses the U-shaped plate 703. The cooperation of the second spring 709 and the top ring 710 achieves the effect of automatically resetting the U-shaped plate 703. A reset plate 711 is fixedly connected to the arc surface of the rotating shaft 3, and a rotating plate 712 is fixedly connected to the upper end of the column 2. The rotating shaft 3 drives the reset plate 711 to rotate. When the reset plate 711 contacts the rotating plate 712, the rotating plate 712 prevents the reset plate 711 from continuing to rotate, thereby limiting the position of the rotating shaft 3 and causing the mounting plate 4 to return to a horizontal state.

[0054] Reference Figure 2 and Figure 9 as well as Figure 10As shown, specifically, a strip plate 82 is rotatably connected to the inner wall of the base 81. A counterweight 83 is slidably fitted onto the surface of the strip plate 82. The counterweight 83 is made of stainless steel. A rectangular tube 84 is slidably fitted onto the surface of the strip plate 82. A screw 85 is threaded into the side wall of the rectangular tube 84. The screw 85 passes through the rectangular tube 84 and abuts against the surface of the strip plate 82. A hanging rope 88 is fixedly connected to the side wall of the rectangular tube 84. A hook 89 is fixedly connected to the side of the column 2 near the hanging rope 88. The hanging rope 88 is fitted onto the arc surface of the hook 89. To avoid tilting the base 1 as much as possible, the hanging rope 88 is removed from the arc surface of the hook 89. Then, the strip plate 82 is rotated along the inner wall of the base 81. When the strip plate 82 contacts the bottom of the inner wall of the base 81, the base 81 will prevent the strip plate 82 from continuing to rotate. Then, the strip plate 82 is rotated along the surface of the strip plate 82 towards the rectangular tube 82. The counterweight 83 slides in the direction of the rectangular tube 84. When the screw 85 abuts against the surface of the strip plate 82, the counterweight 83 lowers the center of gravity of the pipe-laying device, preventing the chassis 1 from tilting and thus improving the stability of the pipe-laying device. When it is necessary to adjust the number of counterweights 83, the screw 85 is rotated. The screw 85 will move by the thread and disengage from the strip plate 82. Then the rectangular tube 84 can be removed from the surface of the strip plate 82. The number of counterweights 83 can then be increased or decreased. After adjustment, the rectangular tube 84 is put back on the surface of the strip plate 82, and the screw 85 is rotated in the opposite direction. When the screw 85 abuts against the surface of the strip plate 82, the screw 85 restricts the position of the rectangular tube 84, thus preventing the counterweights 83 from falling off the surface of the strip plate 82. A support plate 86 is fixedly connected to the surface of the chassis 1. A buffer strip 87 is fixedly connected to the upper surface of the support plate 86. The buffer strip 87 is made of rubber and is located below the counterweight 83. The counterweight 83 will slide down the surface of the strip plate 82 due to its own weight. The bottom counterweight 83 will contact the rubber buffer strip 87. The buffer strip 87 will be deformed under pressure to buffer the counterweight 83, thereby preventing the counterweight 83 from damaging the base 81 as much as possible.

[0055] Reference Figure 1-12 As shown, a specific method for laying a building drainage pipe includes the following processing steps:

[0056] S1. Adjust the center of gravity of the pipe laying device with the aid of counterweight 83 according to the size and weight of the drainage pipe 11.

[0057] S2. Clamp the drain pipe 11 with the help of the clamp 613;

[0058] S3. Start the servo motor 605 and use the reel 601 to wind up the strap 602, thereby lifting the drain pipe 11.

[0059] S4. Rotate the rotating ring 705, and adjust the drain pipe 11 to the required angle by means of the lead screw 702, rack 707 and gear ring 708;

[0060] S5. With the help of the electric telescopic rod 9 and the support plate 10, the height of the drain pipe 11 is finely adjusted so that the drain pipe 11 is aligned with other drain pipes 11.

[0061] S6. Connect and install the drain pipe 11 with other drain pipes 11.

[0062] Working principle: During the construction of drainage pipe laying, the support frame 607 is moved downwards. The movement of the support frame 607 will drive the slide rod 612 to move, and the movement of the slide rod 612 will drive the clamping plate 613 to move. When the lower end of the clamping plate 613 abuts against the arc surface of the drainage pipe 11, the support frame 607 is pressed further. Since the contact point between the clamping plate 613 and the drainage pipe 11 is an arc structure, the arc surface of the drainage pipe 11 can squeeze the clamping plate 613, causing the two clamping plates 613 to slide away from each other, thus facilitating the operation of the workers. At this time, the two clamping plates 613 will drive the slide rod 612 to slide away from each other along the inner wall of the inclined hole 611. The round rod 618 achieves the function of restricting the sliding path of the slide rod 612. The square plate 616 slides with the help of the slide rod 612. When the first spring 617 is stretched, it is in a stretched state. Simultaneously, the sliding rod 612 causes the square plate 616 to slide upwards. The sliding of the square plate 616 causes the synchronizing rod 619 to slide along the inner wall of the support frame 607. The synchronizing rod 619 ensures that the two square plates 616 slide synchronously, thus limiting the sliding path of the two clamping plates 613. As the support frame 607 continues to slide, the two clamping plates 613 slide closer to each other under the tension of the first spring 617, clamping the drain pipe 11. At this time, the two sliding rods 612 also slide closer to each other. When the sliding rod 612 slides to the bottom of the inner wall of the inclined hole 611, the threaded column 614 is rotated. The threaded column 614 then moves towards the drain pipe using the screw thread... The threaded positioning plate 615 slides along the surface of the clamping plate 613, preventing the positioning plate 615 from rotating with the threaded post 614. The sliding positioning plate 615 contacts the drain pipe 11, further restricting its position. Then, the servo motor 605 is activated, its output rotating to drive the reel 601. The reel 601 then winds up the strap 602, causing it to slide along the adjusting roller 604. The adjusting roller 604 rotates along the inner wall of the rectangular hole 603 due to the pressure from the strap 602, thus adjusting the angle of the strap 602 as it passes through the adjusting roller 604, reducing wear and extending its service life. The sliding of strap 602 lifts support rod 606, which in turn moves support frame 607. Sliding rod 612, aided by support frame 607, moves clamping plate 613, which in turn moves drain pipe 11. During this process, because sliding rod 612 is located at the bottom of the inner wall of inclined hole 611, the two clamping plates 613 will not slide away from each other due to the gravity of drain pipe 11. This achieves the purpose of clamping and lifting drain pipe 11. Furthermore, when lifting drain pipe 11, manual lifting of drain pipe 11 is not required, making operation more convenient. As support rod 606 and drain pipe 11 move upwards, they will successively contact baffle 620. At this time, baffle 620 will guide the movement path of support rod 606 and drain pipe 11.The support rod 606 first slides between the two baffles 620, and the two support frames 607 slide to both sides of the fixed plate 5. When the drain pipe 11 tilts and rotates during its upward movement, the baffle 620, with its arc-shaped structure on the side away from the fixed plate 5, can guide and adjust the posture of the drain pipe 11. As the drain pipe 11 continues to move, it will contact the two baffles 620. The baffle 620, with its vertical "V"-shaped cross-section, in conjunction with the clamping plate 613, can restrict the position of drain pipes 11 of different diameters. Then, the electric actuator 609 is activated. The output end of the electric actuator 609 extends, causing the push plate 610 to move closer to the circular plate 608. After the push plate 610 contacts the circular plate 608, the servo motor 605 is turned off. At this time, the push plate 610 restricts the position of the circular plate 608, thereby restricting the position of the rotating shaft 3, and thus preventing the strap 602 from loosening, which would cause the drain pipe 11 to move downward.

[0063] When the angle of the drain pipe 11 needs to be adjusted, rotate the rotating plate 712 to disengage it from the reset plate 711, and press the rotating ring 705 towards the bracket 701. The cross plate 704 moves with the help of the rotating ring 705, which causes the U-shaped plate 703 to slide along the arc surface of the lead screw 702. The sliding of the U-shaped plate 703 will compress the top ring 710, and the sliding of the top ring 710 will compress the second spring 709, putting the second spring 709 in a compressed state. The cross plate 704 continues to slide, causing the inner wall of the socket to slide along the surface of the hexagonal block 706. Then, rotate the rotating ring 705, and the cross plate 704 moves with the help of the rotating ring. Rotating ring 705 will cause hexagonal block 706 to rotate, which in turn will cause lead screw 702 to rotate. Lead screw 702 will then drive rack 707 to move via its thread. Rack 707's movement will drive gear ring 708 to rotate, which in turn will drive rotating shaft 3 to rotate. Mounting plate 4, via rotating shaft 3, will drive fixing plate 5 to rotate. Fixing plate 5, in conjunction with baffle 620, will drive drain pipe 11 to rotate, thereby adjusting the angle of drain pipe 11 for easier installation. After adjustment, release rotating ring 705. At this point, second spring 709 will extend, and top ring 710... The tension of the second spring 709 will cause the top ring 710 to move closer to the hexagonal block 706. The movement of the top ring 710 will press against the U-shaped plate 703. The sliding of the U-shaped plate 703 will disengage the insertion hole from the hexagonal block 706. Even if the rotating ring 705 is accidentally touched, the lead screw 702 will not rotate, thus minimizing the risk of the drain pipe 11 changing angle and affecting installation. After installation, when the mounting plate 4 needs to be adjusted back to a horizontal position, rotate the rotating plate 712 in the opposite direction. Then, place the cross plate 704 on the surface of the hexagonal block 706 and rotate the rotating ring 705. At this time, the rotating shaft 3 will... The reset plate 711 is rotated. When the reset plate 711 contacts the rotating plate 712, the rotating plate 712 will prevent the reset plate 711 from continuing to rotate, thereby limiting the position of the rotating shaft 3 and causing the mounting plate 4 to return to a horizontal state. When it is necessary to adjust the height of the drain pipe 11, the electric telescopic rod 9 is activated. The extension of the output end of the electric telescopic rod 9 will drive the support plate 10 to move downward. After the support plate 10 touches the ground, the extension of the output end of the electric telescopic rod 9 will cause the chassis 1 to move upward. The column 2 will move with the help of the chassis 1 and eventually drive the drain pipe 11 to move upward, thereby further facilitating the installation of the drain pipe 11.

[0064] During the lifting of the drainage pipe 11, to avoid tilting of the chassis 1 as much as possible, remove the hanging rope 88 from the arc surface of the hook 89, and then rotate the strip plate 82 along the inner wall of the base 81. When the strip plate 82 contacts the bottom of the inner wall of the base 81, the base 81 will prevent the strip plate 82 from continuing to rotate. Then, slide the counterweight 83 along the surface of the strip plate 82 towards the rectangular pipe 84. When the screw 85 abuts against the surface of the strip plate 82, the counterweight 83 lowers the center of gravity of the pipe laying device, preventing the chassis 1 from tilting and thus improving the stability of the pipe laying device. When it is necessary to adjust the number of counterweights 83, rotate the screw 85. The screw 85 will disengage from the strip plate 82 by moving with the thread, and then the rectangular pipe 84 can be removed from the surface of the strip plate 82. Then the number of counterweights 83 can be increased or decreased. After adjustment, the rectangular tube 84 is re-attached to the surface of the strip plate 82, and the screw 85 is rotated in the opposite direction. When the screw 85 abuts against the surface of the strip plate 82, the screw 85 restricts the position of the rectangular tube 84. At this time, the rectangular tube 84 helps to prevent the counterweight 83 from falling off the surface of the strip plate 82. When the counterweight structure 8 is not needed, the strip plate 82 is rotated in the opposite direction. At this time, the counterweight 83 will slide down the surface of the strip plate 82 due to its own weight. The bottom counterweight 83 will come into contact with the rubber buffer strip 87. The buffer strip 87 will be deformed under pressure and will cushion the counterweight 83, thereby preventing the counterweight 83 from damaging the base 81. Then, the hanging rope 88 is re-attached to the arc surface of the hook 89. The hook 89 restricts the position of the hanging rope 88 and thus restricts the position of the strip plate 82.
