[0002] At present, municipal water supply is the most basic guarantee for human survival in cities. Water resources need to be transported through municipal water supply pipelines to maintain the normal operation of cities. Municipal areas have a large water consumption and drainage volume. Therefore, it is often necessary to install water pipes under municipal roads to facilitate the transportation of daily water, sewage and other liquids. The installation steps of the pipeline are as follows: prepare materials and equipment such as water pipes and dig installation trenches, use a crane to hang the water pipes into the installation trenches, and workers will splice and seal the two adjacent water pipes to form a water supply pipeline, and then bury the pipeline, so as to form a municipal water supply pipeline.

[0003] However, during the pipeline installation process, the water pipe is lowered into the installation groove by a crane. Due to the softness of the hanging rope, it is not easy to connect the water pipe to the pipeline mouth, so manual correction or movement is required, which reduces the efficiency of pipeline installation. Further improvement is needed. Summary of the invention

The slide plate drives the vertical moving component to move in the horizontal direction, and then makes the clamping component move in the horizontal direction, so as to realize the horizontal alignment of the pipe to be installed and the installed pipe.

[0009] Preferably, the first positioning device includes a first cylinder, a first movable frame, a second cylinder, a second movable frame and a positioning plate, the first cylinder and the second cylinder are symmetrically arranged, and the first cylinder and the second cylinder are fixedly connected to the support frame; the first movable frame and the second movable frame are both located between the first cylinder and the second cylinder, the first movable frame is fixedly connected to the first cylinder, and the second movable frame is fixedly connected to the second cylinder, the first movable frame and the second movable frame are both sleeved on the first sliding rod, the first movable frame and the second movable frame are slidably connected to the first sliding rod, and the first movable frame and the second movable frame are respectively located on both sides of the slide plate; at least one group of positioning plates is provided, and each group of positioning plates is symmetrically provided with two positioning plates, the positioning plates are arranged between the first movable frame and the second movable frame, and the two positioning plates in the same group are connected to the first movable frame and the second movable frame The racks correspond one to one, the first movable rack is fixedly connected to the corresponding positioning plate, and the second movable rack is fixedly connected to the corresponding positioning plate; a first groove is provided on the positioning plate, and a first sensor is arranged in the first groove close to the first movable rack, the first sensor is fixedly connected to the positioning plate, and the first sensor is used to detect the distance between the positioning plate close to the first movable rack and the installed pipeline; a second sensor is arranged in the first groove close to the second movable rack, the second sensor is fixedly connected to the positioning plate, and the second sensor is used to detect the distance between the positioning plate close to the second movable rack and the installed pipeline, and when multiple positioning plates are in contact with the installed pipeline, the first movable rack and the second movable rack are both in contact with the slide plate; the first sensor is electrically connected to a control module, and the second sensor, the first cylinder, and the second cylinder are all electrically connected to the control module.

[0011] The first sensor and the second sensor transmit the distance signal between themselves and the installed pipe to the control module. The distance between the first sensor and the installed pipe is always equal to the distance between the second sensor and the installed pipe. When the distances of one of the two are different, if the distance of the first sensor is larger, the control module transmits the electrical signal to the second cylinder, so that the second cylinder stops driving the second moving frame until the distance between the first sensor and the installed pipe is equal to the distance between the second sensor and the installed pipe, and then starts the second cylinder.

[0053] The first sensor 654 and the second sensor 655 transmit the distance signal between the positioning plate 65 connected to themselves and the installed pipe to the control module. The distance between the first sensor 654 and the installed pipe is always equal to the distance between the second sensor 655 and the installed pipe. When the first sensor 654 senses that the positioning plate 65 near the first mobile frame 62 is in contact with the pipe, the first sensor 654 transmits an electrical signal to the control module, and the control module sends a signal to pause the first cylinder 61. When the second sensor 655 senses that the positioning plate 65 near the second mobile frame 64 is in contact with the pipe, the second sensor 655 transmits an electrical signal to the control module, and the control module sends a signal to pause the second cylinder 63.

[0054] Reference Figure 7 The side walls of the two positioning plates 65 close to each other are connected to the limiting device 7. The limiting device 7 includes a limiting plate 71, a control rod 72, a first spring 73, a rack 74, a gear 75, a threaded rod 76 and a baffle 77. The limiting plate 71 is fixedly connected to the positioning plate 65. A through hole 711 is provided on the side wall of the limiting plate 71 away from the positioning plate 65, and an active cavity 653 is provided in the positioning plate 65, and the active cavity 653 is connected to the through hole 711. A sliding groove 652 is provided on the side wall of the positioning plate 65 close to the limiting plate 71, and the sliding groove 652 is vertically arranged and connected to the first groove 651.

[0055] Reference Figure 7 The control rod 72 passes through the through hole 711 and extends into the active cavity 653, and the control rod 72 is slidably connected to the limit plate 71. The first spring 73 is arranged in the through hole 711, one end of the first spring 73 is fixedly connected to the limit plate 71, and the other end is fixedly connected to the control rod 72.

[0056] Reference Figure 7 The first end of the rack 74 is disposed in the movable cavity 653, and the second end of the rack 74 extends into the through hole 711 and is fixedly connected to the control rod 72. The gear 75 is disposed in the movable cavity 653 and is rotatably connected to the positioning plate 65. The threaded rod 76 is disposed in the movable cavity 653, and the threaded rod 76 passes through the gear 75 and is threadedly connected to the gear 75. The bottom end of the threaded rod 76 passes through the positioning block 85 and extends into the slide groove 652. The baffle plate 77 is disposed in the slide groove 652 and is slidably connected to the positioning plate 65, and the baffle plate 77 is fixedly connected to the threaded rod 76.

[0057] When the two positioning plates 65 are in contact with the installed pipes, the limit plate 71 is located above the pipes, the two limit plates 71 are in contact with each other, the control rod 72 retracts into its respective through hole 711, and the control rod 72 drives the rack 74 to move during the movement process, the rack 74 drives the gear 75 to rotate, the gear 75 drives the threaded rod 76 to move, and the threaded rod 76 drives the baffle 77 to move in the slide groove 652. When the positioning plate 65 is in contact with the installed pipes, the baffle 77 blocks the first sensor 654 and the second sensor 655. Even if the first sensor 654 and the second sensor 655 are not located on the same diameter of the installed pipe, the first sensor 654 and the second sensor 655 still transmit electrical signals to the control module after sensing the position of the baffle 77, and the control module transmits the electrical signals to the first cylinder 61 and the second cylinder 63 to pause the first cylinder 61 and the second cylinder 63.

[0058] Reference Figure 8 The second positioning device 8 includes a fixing plate 81, a vertical rod 82, a block 83, a second spring 84, a positioning block 85 and a third sensor 86. The fixing plate 81 is arranged horizontally, and a first end of the fixing plate 81 is fixedly connected to the mounting frame 42. The vertical rod 82 passes through the limiting plate 71 and is slidably connected to the limiting plate 71. The block 83 is fixedly connected to the top of the vertical rod 82. The second spring 84 is arranged between the block 83 and the limiting plate 71. One end of the second spring 84 is fixedly connected to the block 83, and the other end is fixedly connected to the limiting plate 71.

[0059] Reference Figure 8 The positioning block 85 is fixedly connected to the bottom end of the vertical rod 82, and the bottom surface of the positioning block 85 is set in an arc surface and matches the outer wall of the installed pipeline. The bottom surface of the positioning block 85 is provided with a second groove 851, and the third sensor 86 is arranged in the second groove 851 and fixedly connected to the positioning block 85. The third sensor 86 is electrically connected to the control module. When the positioning block 85 abuts against the installed pipeline, the second end of the fixing plate 81 abuts against the clamping block 83, and the axis of the pipeline to be installed coincides with the axis of the installed pipeline.

[0060] After the horizontal position of the pipe to be installed is determined, when the mounting frame 42 moves in the vertical direction, the mounting frame 42 drives the fixing plate 81 to move in the vertical direction. After the fixing plate 81 contacts the clamping block 83, the fixing plate 81 drives the clamping block 83 to move. The clamping block 83 drives the vertical rod 82 to move and compresses the second spring 84. The vertical rod 82 drives the positioning block 85 to move until the positioning block 85 contacts the pipe to be installed. After the third sensor 86 senses the position of the pipe, it transmits an electrical signal to the control module. The control module transmits the electrical signal to the hydraulic cylinder 41. The hydraulic cylinder 41 stops moving. At this time, the axis of the clamped pipe to be installed coincides with the axis of the installed pipe. Restarting the transport motor 511 can accurately dock the pipe to be installed with the installed pipe, thereby improving the efficiency of pipe installation.

[0061] The use principle of the present application is as follows: when the pipeline to be installed is docked with the installed pipeline, the hydraulic cylinder 41 is started, and the hydraulic cylinder 41 drives the mounting frame 42 to move downward, and the mounting frame 42 drives the transport assembly 51 and the clamping assembly 52 to move downward, so that the clamping assembly 52 is close to the pipeline to be installed. Then the clamping motor 521 is started, and the clamping motor drives the bidirectional lead screw 522 to move, and the bidirectional lead screw 522 drives the first clamping plate 523 and the second clamping plate 524 to move closer to each other, and the first clamping plate 523 and the second clamping plate 524 cooperate to clamp the pipeline to be installed. Then the hydraulic cylinder 41 is started again, and the hydraulic cylinder 41 drives the transport assembly 51 and the clamping assembly 52 to reset through the mounting frame 42.

[0062] Start the first cylinder 61 and the second cylinder 63, the first cylinder 61 drives the first moving frame 62 to move, the first moving frame 62 drives the positioning plate 65 connected to itself to move; the second cylinder 63 drives the second moving frame 64 to move, the second moving frame 64 drives the positioning plate 65 connected to itself to move. The first sensor 654 and the second sensor 655 transmit the distance signal between the positioning plate 65 connected to themselves and the installed pipe to the control module, and the distance between the first sensor 654 and the installed pipe is always equal to the distance between the second sensor 655 and the installed pipe.

[0063] No matter the first mobile frame 62 or the second mobile frame 64 abuts against the slide plate 33, the slide plate 33 will be driven to move. When the first sensor 654 senses that the positioning plate 65 near the first mobile frame 62 abuts against the pipeline, the first sensor 654 transmits an electrical signal to the control module, and the control module sends a signal to pause the first cylinder 61. When the second sensor 655 senses that the positioning plate 65 near the second mobile frame 64 abuts against the pipeline, the second sensor 655 transmits an electrical signal to the control module, and the control module sends a signal to pause the second cylinder 63. At this time, the first mobile frame 62 and the second mobile frame 64 are both in contact with the slide plate 33, and the position of the slide plate 33 is determined, that is, the positions of the vertical moving component 4, the second positioning device 8, the transport component 51, and the clamping component 52 in the horizontal direction are all determined, and the position of the pipeline to be installed in the horizontal direction is determined.

[0064] When the horizontal position of the pipeline to be installed is determined, the hydraulic cylinder 41 is started to move the mounting frame 42 in the vertical direction. The mounting frame 42 drives the pipeline to be installed downward through the transport assembly 51 and the clamping assembly 52. ​​At the same time, the mounting frame 42 drives the fixed plate 81 downward. After the fixed plate 81 abuts against the clamping block 83, the fixed plate 81 drives the clamping block 83 to move. The clamping block 83 drives the vertical rod 82 to move and compresses the second spring 84. The vertical rod 82 drives the positioning block 85 to move until the positioning block 85 abuts against the pipeline to be installed. After the third sensor 86 senses the position of the pipeline, it transmits an electrical signal to the control module. The control module transmits the electrical signal to the hydraulic cylinder 41, and the hydraulic cylinder 41 stops moving. At this time, the clamped pipeline to be installed coincides with the axis of the installed pipeline, that is, the vertical position of the pipeline to be installed is determined.

[0065] Start the transport motor 511, which drives the transport screw 512 to rotate. The transport screw 512 cooperates with the guide rod 513 to realize the movement of the transport frame 514 along the length direction of the installed pipe. The transport frame 514 drives the clamping assembly 52 to move, so that the clamping assembly 52 is close to the installed pipe, thereby realizing the splicing of the pipe to be installed and the installed pipe.

At the same time, the vertical moving component 4 drives the second positioning device 8 to move.
