Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to a water supply and drainage pipeline installation and docking device. Background Technology

[0002] In the prior art, such as the water supply and drainage pipe installation and docking device disclosed on the Chinese patent website with announcement number CN221121196U, a lateral adjustment mechanism is set on the crossbar to simultaneously adjust the distance and length between two sets of clamping plate assemblies, so that the clamping plate assemblies can quickly clamp and fix pipes of different diameters. By setting a driving mechanism, the two sets of lateral adjustment mechanisms can be driven synchronously, thereby improving the convenience of device operation. By setting a longitudinal adjustment mechanism on the vertical bar to adjust the distance between the two crossbars, the docking work of two pipes can be completed quickly, and the central axes of the two pipes can be ensured to be on the same straight line.

[0003] However, in actual use, when workers are connecting pipes at different locations, they need to move the connection device. However, the device does not have a moving mechanism, so workers need to manually move the connection device to the required location, which reduces work efficiency. In addition, pipe connections have different height requirements, and the height adjustment of the device's clamping plate and the clamping action are tied together, making it impossible to freely adjust the clamping height. Utility Model Content

[0004] To address the existing technical problems of the inability to move freely and adjust the clamping height freely, this utility model proposes a water supply and drainage pipeline installation and docking device.

[0005] This utility model proposes a water supply and drainage pipeline installation and docking device, including a top plate, support rods fixedly installed at the four lower corners of the top plate, an electric telescopic rod fixedly installed at the upper part of the top plate, the telescopic end of the electric telescopic rod penetrating and extending to the lower part of the top plate, a moving mechanism provided at the lower part of the support rod, and a docking mechanism provided at the lower part of the top plate.

[0006] Preferably, the moving mechanism includes a rotating rod, the arcuate surface of which is rotatably connected to the lower side of the support rod via ball bearings. Both ends of the rotating rod extend through and out of the lower sides of the support rod. A limit block is fixedly installed at one end of the rotating rod, and one side surface of the limit block is in contact with the side of the support rod. A support column is fixedly installed on the arcuate surface of the other end of the rotating rod. A mounting plate is rotatably connected to the lower end of the support column via ball bearings. A support plate is fixedly installed on the lower part of the mounting plate. The opposing surfaces of the two support plates are rotatably connected to a rotating shaft via ball bearings. A moving wheel is fixedly connected to the arcuate surface of the rotating shaft.

[0007] The above technical solution, by setting up movable wheels, allows workers to easily push the device to move quickly to the location where water supply and drainage pipes need to be installed. The mounting plate is rotatably connected to the lower end of the support column, allowing the movable wheels to rotate 360°, so that the device can rotate freely without restriction.

[0008] Preferably, the lower surface of the support rod is further threaded with a fixing bolt, one end of which penetrates and extends out of one side of the support rod, and the threaded surface of the fixing bolt is also threadedly connected to the arc surface of the rotating rod.

[0009] By using the above technical solution, a fixing bolt is set, and the fixing bolt is unscrewed so that the rotating rod is not limited by the fixing bolt, allowing the rotating rod to rotate. This allows the moving wheel to rotate around the rotating rod in the vertical direction. After the moving wheel rotates 180°, the fixing bolt is screwed back in to re-limit and fix the rotating rod, which allows the moving wheel to leave the ground and the lower part of the support rod to contact the ground, preventing the device from moving erratically.

[0010] Preferably, the docking mechanism includes a movable plate, which is fixedly installed at the lower part of the telescopic end of the electric telescopic rod. A second support plate is fixedly installed at the lower part of the movable plate. The opposing surfaces of the two second support plates are rotatably connected to a bidirectional screw via ball bearings. A motor is fixedly installed on one side of one second support plate. The output end of the motor is fixedly connected to one end of the bidirectional screw via a coupling. A first limit rod is fixedly installed on the opposing surfaces of the two second support plates. A sliding plate is threadedly connected to the left-hand threaded surface and the right-hand threaded surface of the bidirectional screw. The outer surface of the sliding plate is also slidably inserted into the arc surface of the two first limit rods.

[0011] The above technical solution involves setting up a movable plate, which can move up and down with the docking mechanism under the action of the electric telescopic rod, so that the docking mechanism can meet the docking requirements of pipes at different heights. A bidirectional screw is also set up. When the motor drives the bidirectional screw to rotate, the two sliding plates move towards each other under the limit of the first limiting rod, that is, they move inward or outward synchronously.

[0012] Preferably, a support plate three is fixedly installed on one side of the lower part of the sliding plate. A threaded rod one is threadedly connected to the surface of the support plate three. The threaded rod one passes through and extends to both sides of the support plate three. An arc-shaped clamping block one is rotatably connected to one end of the threaded rod one via a ball bearing. A limiting rod two is also slidably inserted into the surface of the support plate three. The limiting rod two passes through and extends out of both sides of the support plate three. One end of each of the two limiting rod two is fixedly connected to the outer arc-shaped surface of the arc-shaped clamping block one. A moving block one is fixedly installed at the other end of the two limiting rod two. An arc-shaped surface of one end of the threaded rod one is rotatably connected to one side surface of the moving block one via a ball bearing. One end of the threaded rod one passes through and extends out of one end of the moving block one. A rotating disk one is fixedly installed at the end of the threaded rod one extending out of the moving block one.

[0013] The above technical solution involves setting up a rotating disk 1. When the operator rotates the rotating disk 1, it drives the threaded rod 1 to rotate. Under the limiting action of the limiting rod 2, it drives the circular clamping plate 1 to move inward. A moving block 1 is set up to limit the distance that the circular clamping plate 1 moves inward.

[0014] Preferably, a support plate four is fixedly installed on the lower side of the sliding plate. A threaded rod two is threadedly connected to the surface of the support plate four. The threaded rod two passes through and extends to both sides of the support plate four. An arc-shaped clamping block two is rotatably connected to one end of the threaded rod two via a ball bearing. A limiting rod three is also slidably inserted into the surface of the support plate four. The limiting rod three passes through and extends out of both sides of the support plate four. One end of each of the two limiting rod three is fixedly connected to the outer arc-shaped surface of the arc-shaped clamping block two. A moving block two is fixedly installed at the other end of each of the two limiting rod three. An arc-shaped surface of one end of the threaded rod two is rotatably connected to one side surface of the moving block two via a ball bearing. One end of the threaded rod two passes through and extends out of one end of the moving block two. A rotating disk two is fixedly installed at the end of the threaded rod two extending out of the moving block two.

[0015] Through the above technical solution, a rotating disk two is set up. When the operator rotates the rotating disk two, it drives the threaded rod two to rotate. Under the limiting action of the limiting rod three, it drives the circular clamping plate two to move inward. A moving block two is set up to limit the distance that the circular clamping plate two moves inward.

[0016] Preferably, the inner arc sidewalls of the first and second arc clamps are respectively fixedly connected with anti-slip rubber pads, a laser emitter is fixedly installed on the outer arc surface of the first and second arc clamps at the lower part of one of the sliding plates, and a light sensor is fixedly installed on the outer arc surface of the first and second arc clamps at the lower part of the other sliding plate.

[0017] The above technical solution involves setting up anti-slip rubber pads. When circular clamping plates one and two clamp the pipe, the anti-slip rubber pads increase friction, making the clamping and fixing more stable. At the same time, they can also protect the outer wall of the pipe. A laser emitter and a light sensor are set up. By rotating rotating disk one and rotating disk two, the positions of circular arc clamping blocks one and two can be adjusted, allowing the clamped and fixed pipe to be positioned. When the light sensor receives the light signal emitted by the laser emitter, it indicates that the two pipes that need to be connected are on the same central axis. Starting the motor will cause the two sliding plates to move the two pipes closer to each other, allowing the staff to complete the connection of the water supply and drainage pipes.

[0018] The beneficial effects of this utility model are as follows:

[0019] By setting up a moving mechanism, the device can be moved freely, making it convenient for staff to move to the location where pipes need to be connected. It is equipped with an electric telescopic rod, which can move the connection mechanism up and down when the electric telescopic rod is activated. This allows the connection mechanism to meet the connection needs of water supply and drainage pipes of different heights, solving the existing technical problems of not being able to move freely and not being able to freely adjust the clamping height.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A water supply and drainage pipeline installation and docking device includes a top plate 1, support rods 2 are fixedly installed at the four lower corners of the top plate 1, an electric telescopic rod 3 is fixedly installed on the upper part of the top plate 1, the telescopic end of the electric telescopic rod 3 passes through and extends to the lower part of the top plate 1, a moving mechanism is provided at the lower part of the support rods 2, and a docking mechanism is provided at the lower part of the top plate 1.

[0028] To facilitate the movement of the docking device, a moving mechanism is provided. The moving mechanism includes a rotating rod 4. The arc surface of the rotating rod 4 is rotatably connected to the lower side of the support rod 2 via ball bearings. Both ends of the rotating rod 4 extend through and out of the lower sides of the support rod 2. A limit block 5 is fixedly installed at one end of the rotating rod 4. One side surface of the limit block 5 is in contact with the side of the support rod 2. A support column 6 is fixedly installed on the arc surface of the other end of the rotating rod 4. The lower end of the support column 6 is rotatably connected to a mounting plate 7 via ball bearings. A support plate 8 is fixedly installed on the lower part of the mounting plate 7. The opposing surfaces of the two support plates 8 are rotatably connected to a rotating shaft 9 via ball bearings. A moving wheel 10 is fixedly connected to the arc surface of the rotating shaft 9.

[0029] By setting the movable wheels 10, the staff can easily push the device to move it and quickly move it to the location where water supply and drainage pipes need to be installed. The mounting plate 7 is rotatably connected to the lower end of the support column 6, so that the movable wheels 10 can rotate 360°, allowing the device to move freely without restriction.

[0030] To allow the movable wheel 10 to retract, a fixing bolt 11 is threaded onto the lower surface of the support rod 2. One end of the fixing bolt 11 passes through and extends out of one side of the support rod 2, and the threaded surface of the fixing bolt 11 is also threaded onto the arc surface of the rotating rod 4. By setting the fixing bolt 11 and unscrewing it, the rotating rod 4 is no longer limited by the fixing bolt 11, allowing the rotating rod 4 to rotate. This allows the movable wheel 10 to rotate around the rotating rod 4 in the vertical direction. After the movable wheel 10 has rotated 180°, the fixing bolt 11 is screwed back in to re-limit and fix the rotating rod 4, thus allowing the movable wheel 10 to leave the ground and the lower part of the support rod 2 to contact the ground, preventing the device from moving erratically.

[0031] To facilitate clamping and docking of water supply and drainage pipes, a docking mechanism is provided. The docking mechanism includes a movable plate 12, which is fixedly installed at the lower part of the telescopic end of the electric telescopic rod 3. A second support plate 13 is fixedly installed at the lower part of the movable plate 12. The opposing surfaces of the two second support plates 13 are rotatably connected to a double-acting screw 14 via ball bearings. A motor 15 is fixedly installed on one side of one second support plate 13. The output end of the motor 15 is fixedly connected to one end of the double-acting screw 14 via a coupling. Limiting rods 16 are fixedly installed on the opposing surfaces of the two second support plates 13. The left-hand threaded surface and the right-hand threaded surface of the double-acting screw 14 are respectively threaded with sliding plates 17. The outer surface of the sliding plates 17 is also slidably inserted into the arc surfaces of the two limiting rods 16.

[0032] By setting the movable plate 12, the movable plate 12 can move up and down with the docking mechanism under the action of the electric telescopic rod 3, so that the docking mechanism can meet the docking requirements of pipes at different heights. A bidirectional screw 14 is set. When the motor 15 drives the bidirectional screw 14 to rotate, the two sliding plates 17 move towards each other under the limit of the limit rod 16, that is, move inward or outward synchronously.

[0033] To achieve separate control of pipe clamping, a support plate 3 18 is fixedly installed on one side of the lower part of the sliding plate 17. A threaded rod 19 is threadedly connected to the surface of the support plate 3 18. The threaded rod 19 passes through and extends to both sides of the support plate 3 18. An arc-shaped clamping block 20 is rotatably connected to one end of the threaded rod 19 via a ball bearing. Limiting rods 21 are also slidably inserted into the surface of the support plate 3 18. The limiting rods 21 pass through and extend to both sides of the support plate 3 18. One end of each limiting rod 21 is fixedly connected to the outer arc surface of the arc clamping block 20. A moving block 22 is fixedly installed at the other end of each limiting rod 21. The arc-shaped surface of one end of the threaded rod 19 is rotatably connected to one side surface of the moving block 22 via a ball bearing. One end of the threaded rod 19 passes through and extends to one end of the moving block 22. A rotating disk 23 is fixedly installed at the end of the threaded rod 19 extending from the moving block 22.

[0034] By setting a rotating disk 23, when the operator rotates the rotating disk 23, it drives the threaded rod 19 to rotate. Under the limiting action of the limiting rod 21, it drives the circular clamping plate 1 to move inward. A moving block 22 is set to limit the distance the circular clamping plate 1 moves inward.

[0035] To achieve separate control of pipe clamping, a support plate 24 is fixedly installed on one side of the lower part of the sliding plate 17. A threaded rod 25 is threadedly connected to the surface of the support plate 24. The threaded rod 25 passes through and extends to both sides of the support plate 24. One end of the threaded rod 25 is rotatably connected to an arc-shaped clamping block 26 via a ball bearing. Limiting rods 27 are also slidably inserted into the surface of the support plate 24. The limiting rods 27 pass through and extend to both sides of the support plate 24. One end of each limiting rod 27 is fixedly connected to the outer arc surface of the arc-shaped clamping block 26. The other end of each limiting rod 27 is fixedly installed with a moving block 28. One end of the threaded rod 25 is rotatably connected to one side surface of the moving block 28 via a ball bearing. One end of the threaded rod 25 passes through and extends out of one end of the moving block 28. A rotating disk 29 is fixedly installed at the end of the threaded rod 25 extending out of the moving block 28.

[0036] By setting up a rotating disk 29, when the operator rotates the rotating disk 29, it drives the threaded rod 25 to rotate. Under the limiting action of the limiting rod 3 27, it drives the circular clamping plate 2 to move inward. A moving block 28 is set up to limit the distance the circular clamping plate 2 moves inward.

[0037] To ensure more accurate pipe connection, anti-slip rubber pads 30 are fixedly connected to the inner arc sidewalls of arc clamp 1 20 and arc clamp 26 respectively. A laser emitter 31 is fixedly installed on the outer arc surface of arc clamp 1 20 and arc clamp 26 under one sliding plate 17, and a light sensor 32 is fixedly installed on the outer arc surface of arc clamp 1 20 and arc clamp 26 under another sliding plate 17.

[0038] By setting up anti-slip rubber pads 30, when circular clamping plates one and two clamp the pipe, the anti-slip rubber pads 30 can increase the friction, making the clamping and fixing more stable, and at the same time, they can protect the outer wall of the pipe. By setting up laser emitter 31 and light sensor 32, the position of circular clamping block one 20 and circular clamping block two 26 can be adjusted by rotating rotating disk one 23 and rotating disk two 29, so that the position of the clamped and fixed pipe can be adjusted. When the light sensor 32 receives the light signal emitted by laser emitter 31, it indicates that the two pipes that need to be connected are on the same central axis. Starting motor 15 can make the two sliding plates 17 move the two pipes closer to each other, so that the staff can complete the connection of water supply and drainage pipes.

[0039] Working principle: First, the operator moves the device to the location where the water supply and drainage pipes need to be connected using the movable wheel 10. Then, the fixing bolt 11 is unscrewed, allowing the rotating rod 4 to rotate without being limited by the fixing bolt 11. This allows the movable wheel 10 to rotate vertically around the rotating rod 4. After the movable wheel 10 rotates 180°, the fixing bolt 11 is screwed back in to re-limit and fix the rotating rod 4, allowing the movable wheel 10 to leave the ground and the lower part of the support rod 2 to contact the ground, preventing it from moving erratically under force during pipe connection. The electric telescopic rod 3 is then activated, allowing the movable plate 12 to move up and down. This moves the arc-shaped clamping blocks 20 and 26 at the bottom of the movable plate 12 to the appropriate positions. Then, rotating the rotating disks 23 and 29 drives the threaded rods 19 and 25 to rotate. The rotation of the threaded rod 19 causes the arc-shaped clamping block 20 to move inward under the limiting action of the limiting rod 21, and the rotation of the threaded rod 25 causes the arc-shaped clamping block 20 to move inward under the limiting action of the limiting rod 21. Under the limiting action of the limiting rod 27, the arc clamp 26 moves inward, and the arc clamp 1 20 and arc clamp 26 move inward to clamp and fix the pipes to be connected. The anti-slip rubber pads 30 set on the inner arc surfaces of the arc clamp 1 20 and arc clamp 26 increase the friction, making the clamping and fixing of the pipes more stable, and at the same time protecting the outer wall of the pipes. Then, by adjusting the fine-tuning rotating disk 1 23 and rotating disk 2 29, the position of the clamped and fixed pipes is finely adjusted left and right, so that the light sensor 32 on the outer arc surface of the arc clamp 1 20 and arc clamp 26 on one side can receive the light emitted by the laser emitter 31 on the outer arc surface of the arc clamp 1 20 and arc clamp 26 on the other side. At this time, it indicates that the two pipes to be connected are on the same central axis. The starting motor 15 drives the bidirectional screw 14 to rotate, causing the two sliding plates 17 to move inward, so that the two clamped and fixed pipes move closer together, making it convenient for the staff to connect the pipes.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
