Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and more particularly to an auxiliary device for building plumbing construction. Background Technology

[0002] In high-rise buildings, heating is generally divided into two zones: high and low. Each zone has its own separate supply and return water pipes. These heating water delivery pipes are centrally located in the water and heating pipe rooms on each floor of the high-rise building.

[0003] Chinese patent application CN112393028A discloses a tooling for installing plumbing pipes in high-rise buildings, solving the problem of convenient pipe connection and welding within the pipe room of a high-rise building. The design includes a frame for supporting welded pipe connections used in a first-floor plumbing room. A vertically adjustable lifting plate is installed on this frame, with jacks positioned between the lifting plate and the frame. A moving track is installed on the top surface of the lifting plate, and a movable pipe support bearing is mounted on the track. A pipe support is placed on the pipe support bearing, and the lower end of the first-floor welded pipe is inserted into the pipe support, making the rotation of the welded pipe easier through the pipe support bearing. After all the welded pipes above the first floor are completed, the jacks are lowered, causing the support plate for the welded pipes to descend and detach from the welded pipes. Finally, the frame is moved horizontally from directly below the welded pipes to facilitate the subsequent welding work between the first-floor pipes and the basement pipes.

[0004] However, the above technical solution does not solve the following problem:

[0005] Because the diameter of the pre-drilled holes in the building is larger than the diameter of the pipe to be installed, when two adjacent pipes are welded together, the center lines of the two adjacent pipes are not collinear, which makes it impossible to guarantee the quality of the welded pipes. Therefore, this article provides an auxiliary device for building plumbing construction. Summary of the Invention

[0006] The purpose of this invention is to provide a building plumbing construction auxiliary device that is simple to operate and improves the installation and welding quality of plumbing pipes.

[0007] This invention is achieved through the following measures:

[0008] A building plumbing construction auxiliary device, characterized in that it includes a base and a pipe clamping mechanism disposed on the base;

[0009] The pipe clamping mechanism includes a vertical rod mounted on the base. The vertical rod is provided with an upper support plate and a lower support plate with identical structures. Both the upper and lower support plates have pipe clamping parts at their free ends. The center lines of the upper and lower pipe clamping parts are collinear. The upper pipe clamping part clamps the upper pipe, and the lower pipe clamping part clamps the lower pipe. In this way, the center lines of the upper and lower pipes are collinear, ensuring the connection quality of the upper and lower pipes.

[0010] The invention also has the following specific features:

[0011] The pipe clamp includes a flat plate portion disposed at the free end of the upper support plate or the lower support plate. The upper support plate or the lower support plate is provided with an arc-shaped portion that cooperates with the flat plate portion via a rotating shaft. The arc-shaped portion is disposed on the inner side of the flat plate portion facing the vertical rod. Since the pipe is close to the wall, it is clamped by the cooperation of the flat plate portion and the arc-shaped portion.

[0012] The pipe clamping mechanism further includes a driving part disposed between the upper support plate and the lower support plate. The driving part includes an upper round rod and a lower round rod. The lower ends of the upper round rod and the lower round rod are provided with transition plates. A cylindrical rod is disposed between the upper and lower transition plates. A round shaft is disposed on the upper end face of the upper round rod and the lower round rod. Correspondingly, the upper support plate and the lower support plate are provided with through holes that cooperate with the round shaft. The round shaft is rotatably disposed in the corresponding through holes. After the round shaft passes through the corresponding through holes on both sides, a connecting plate is disposed.

[0013] Both sides of the connecting plate are provided with a circular shaft 2, and both sides of the arc-shaped part are provided with a circular shaft 3. A connecting plate 2 is movably arranged between the circular shaft 2 and the circular shaft 3 on the corresponding side. Specifically, one end of the connecting plate 2 is rotatably arranged around the circular shaft 2, and the other end of the connecting plate 2 is rotatably arranged around the circular shaft 3.

[0014] Rotating the cylindrical rod causes the transition plate to rotate, which in turn pulls the connecting plate to move, causing the arc-shaped part to rotate around the axis of rotation. This allows the arc-shaped part to open and close relative to the flat plate, ultimately achieving the clamping or loosening of the pipe.

[0015] The flat plate includes a flat plate, and a through rectangular hole is provided in the middle of the flat plate. Several rollers are arranged between the upper and lower sides of the rectangular hole.

[0016] The arc-shaped part includes a mounting plate. One end of the mounting plate is provided with an arc-shaped plate that mates with the flat plate. The mounting plate is located around the rotating shaft. The end of the mounting plate away from the arc-shaped plate is provided with the circular shaft three. A through hole is provided in the middle of the arc-shaped plate. Several rollers two are provided on the upper and lower sides of the through hole. The pipe is clamped by the rollers one and rollers two on both sides. Since the rollers can rotate, the pipe clamped by the pipe clamp can be rotated easily.

[0017] The upper round rod is a telescopic rod, which includes a round tube and an inner rod slidably disposed inside the round tube. The transition plate is provided on the lower side of the round tube, and the round shaft is provided at the upper end of the inner rod. A limiting groove is provided on the side of the round tube, and a limiting rod is provided at the lower end of the inner rod that extends through the limiting groove. The limiting rod and the limiting groove are slidably engaged, and the limiting rod can prevent the inner rod from rotating inside the round tube.

[0018] A sliding groove is provided on the side of the vertical rod. A lead screw is rotatably mounted between the bottom and top surfaces of the sliding groove. A lead screw slider is provided around the lead screw, and an upper support plate is mounted on the lead screw slider. A motor is mounted on the upper end face of the vertical rod. The upper end of the lead screw passes through the top surface of the sliding groove and is mounted on the output end of the motor. The motor drives the lead screw to rotate, which in turn drives the upper support plate to slide, thereby causing the corresponding pipe clamp to move up and down. This allows the upper pipe to be moved downwards to align with the lower pipe end for easier welding.

[0019] A crossbar is provided on the base, and a second sliding groove is provided on the crossbar. A second pipe clamp mechanism, which is symmetrical to the first pipe clamp mechanism, is slidably arranged in the second sliding groove. The second pipe clamp mechanism can facilitate simultaneous operation on two pipes, thereby improving work efficiency.

[0020] The pipe clamp mechanism 1 is rotatably mounted on a pair of brackets 1. Specifically, the bracket 1 is mounted on the lower support plate of the pipe clamp mechanism 1, and a threaded moving block 1 is mounted around the screw 2. The pipe clamp mechanism 2 is mounted on a pair of brackets 2. Specifically, the bracket 2 is mounted on the lower support plate of the pipe clamp mechanism 2, and a moving block 2 is slidably mounted around the guide rail. Both the moving block 1 and the moving block 2 are provided with a sliding groove 3 that mates with the cylindrical rod. The cylindrical rods on both sides are slidably mounted in the sliding groove 3 on the corresponding side. Specifically, the cylindrical rods on the pipe clamp mechanism 1 are mounted in the sliding groove 3 on the moving block 1, and the cylindrical rods on the pipe clamp mechanism 2 are mounted in the sliding groove 3 on the moving block 2.

[0021] The first movable block is provided with a pair of guide grooves, and the second movable block is provided with a pair of guide rods, the guide rods being slidably disposed in the corresponding guide grooves;

[0022] A second motor is provided on one side of the pipe clamping mechanism one. Specifically, the second motor is located on the corresponding side of the vertical rod, and the corresponding end of the second lead screw is located on the output end of the second motor. The second motor drives the second lead screw to rotate, which in turn drives the first moving block and the second moving block to slide, thereby causing the driving parts on both sides to act, thus realizing the clamping or loosening effect of the pipe clamping mechanism one and the pipe clamping mechanism two on the pipe.

[0023] A support plate is provided on one side of the base near the second pipe clamp mechanism. A lead screw three is rotatably mounted on the support plate. A motor three is provided on the first pipe clamp mechanism. Specifically, the motor three is located on the side of the vertical rod of the first pipe clamp mechanism. The free end of the lead screw three is located on the output end of the motor three. A lead screw slider two is provided around the lead screw three. One side of the lead screw slider two is located on the second pipe clamp mechanism. Specifically, the lead screw slider two is located on the vertical rod of the second pipe clamp mechanism.

[0024] The motor three drives the lead screw three to rotate, which in turn drives the pipe clamping mechanism two to slide, thereby facilitating the clamping of the pipe.

[0025] The base has several casters on its lower surface and a push handle on one side.

[0026] The usage method is as follows:

[0027] S1. Assuming there are two sets of pipes that need to be welded and installed, first lower the pipes on both sides through the pre-embedded holes on both sides of the floor slab until the pipe ends on both sides are abutting against the two pipe ends on the lower side.

[0028] S2. Push this device to the vicinity of the pipeline, and then use the motor three to bring the pipe clamp mechanism two closer to the pipe clamp mechanism one until the pipe clamps on both sides can enter between the two pipelines. Then push this device so that the pipe clamps on both sides are aligned with the corresponding pipes. Then use the motor three to slide the pipe clamp mechanism two and adjust this device until the pipes on both sides are in the corresponding pipe clamps. At this time, the upper pipe is in the upper pipe clamp and the lower pipe is in the lower pipe clamp.

[0029] S3. The second motor causes the pipe clamp to clamp the corresponding pipe. Since the center lines of the upper and lower pipe clamps are collinear, the center lines of the upper and lower pipes are also collinear after clamping.

[0030] S4. Since clamping may cause the pipe ports on the upper and lower sides to shift and not make contact, the motor can be used to drive the upper pipe to move down until the pipe ports on the upper and lower sides make contact.

[0031] S5. Start welding. After welding the outer half circle, the pipe can be easily rotated due to the setting of roller one and roller two, so that the unwelded part is exposed.

[0032] The beneficial effects of this invention are as follows: the device has a simple structure and is easy to operate. When connecting pipes, it can make the center lines of the upper and lower pipes collinear, which improves the installation and welding quality of the pipes and is of great significance to building plumbing construction.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0044] See Figure 1-6 A building plumbing construction auxiliary device includes a base 1 and a pipe clamping mechanism disposed on the base 1;

[0045] The pipe clamping mechanism includes a vertical rod 16 mounted on a base 1. The vertical rod 16 is equipped with an upper support plate 6 and a lower support plate 3 with identical structures. Both the upper support plate 6 and the lower support plate 3 have pipe clamping parts at their free ends. The center lines of the upper and lower pipe clamping parts are collinear. The upper pipe clamping part clamps the upper pipe, and the lower pipe clamping part clamps the lower pipe. In this way, the center lines of the upper and lower pipes are collinear, ensuring the connection quality of the upper and lower pipes.

[0046] The pipe clamp includes a flat plate 4 disposed at the free end of the upper support plate 6 or the lower support plate 3. An arc-shaped part 5 that cooperates with the flat plate 4 is disposed on the upper support plate 6 or the lower support plate 3 via a rotating shaft. The arc-shaped part 5 is disposed on the inner side of the flat plate 4 facing the vertical rod 16. Since the pipe is close to the wall, it is clamped by the cooperation of the flat plate 4 and the arc-shaped part 5.

[0047] The pipe clamping mechanism also includes a drive unit 2 disposed between the upper support plate 6 and the lower support plate 3. The drive unit 2 includes an upper round rod and a lower round rod 28. The lower ends of the upper round rod and the lower round rod 28 are provided with transition plates. A cylindrical rod 27 is disposed between the upper and lower transition plates. A round shaft 24 is disposed on the upper end face of the upper round rod and the lower round rod 28. The corresponding upper support plate 6 and the lower support plate 3 are provided with through holes that cooperate with the round shaft 24. The round shaft 24 is rotatably disposed in the corresponding through holes. After the round shaft 24 passes through the corresponding through holes on both sides, a connecting plate 23 is disposed.

[0048] Both sides of the connecting plate 23 are provided with a circular shaft 22, and both sides of the arc-shaped part 5 are provided with a circular shaft 3. A connecting plate 22 and a circular shaft 3 are movably arranged between the corresponding side of the circular shaft 22 and the circular shaft 3. Specifically, one end of the connecting plate 22 is rotatably arranged around the circular shaft 22, and the other end of the connecting plate 22 is rotatably arranged around the circular shaft 3.

[0049] Rotating the cylindrical rod 27 causes the transition plate to rotate, which in turn pulls the connecting plate 7 to move, causing the arc-shaped part 5 to rotate around the axis of rotation. This allows the arc-shaped part 5 to open and close relative to the flat plate part 4, ultimately achieving the clamping or loosening of the pipe.

[0050] The flat plate 4 includes a flat plate, and a through rectangular hole is provided in the middle of the flat plate. Several rollers 31 are arranged between the upper and lower sides of the rectangular hole.

[0051] The arc-shaped part 5 includes a mounting plate. One end of the mounting plate is provided with an arc-shaped plate that mates with the flat plate. The mounting plate is located around the rotating shaft. The end of the mounting plate away from the arc-shaped plate is provided with a round shaft three. A through hole is provided in the middle of the arc-shaped plate. Several rollers two 32 are provided on the upper and lower sides of the through hole. The pipe is clamped by the rollers one 31 and rollers two 32 on both sides. Since the rollers can rotate, the pipe clamped by the pipe clamp can be rotated easily.

[0052] The upper round rod is a telescopic rod, which includes a round tube 26 and an inner rod 25 slidably disposed inside the round tube 26. A transition plate is provided on the lower side of the round tube 26, and a round shaft 24 is provided at the upper end of the inner rod 25. A limiting groove 29 is provided on the side of the round tube 26, and a limiting rod 30 is provided at the lower end of the inner rod 25 that extends through the limiting groove 29. The limiting rod 30 and the limiting groove 29 are slidably engaged, and the limiting rod 30 can prevent the inner rod 25 from rotating inside the round tube 26.

[0053] A groove 34 is provided on the side of the vertical rod 16. A lead screw 35 is rotatably mounted between the bottom and top surfaces of the groove 34. A lead screw slider is provided around the lead screw 35. An upper support plate 6 is mounted on the lead screw slider. A motor 8 is mounted on the upper end face of the vertical rod 16. The upper end of the lead screw 35 passes through the top surface of the groove 34 and is mounted on the output end of the motor 8. The motor 8 drives the lead screw 35 to rotate, which in turn drives the upper support plate 6 to slide, thereby driving the corresponding pipe clamp to move up and down. This allows the upper pipe to be moved downward so that it can contact and align with the lower pipe end, facilitating welding.

[0054] A crossbar 14 is provided on the base 1, and a second sliding groove 13 is provided on the crossbar 14. A second pipe clamp mechanism, which is symmetrical to the first pipe clamp mechanism, is slidably installed in the second sliding groove 13. The second pipe clamp mechanism can facilitate simultaneous operation on two pipes, thus improving work efficiency.

[0055] The pipe clamp mechanism 1 is rotatably mounted with a lead screw 18 via a pair of brackets 1. Specifically, the lower support plate 3 of the pipe clamp mechanism 1 is mounted with bracket 1, and the lead screw 18 is surrounded by a threaded moving block 17. The pipe clamp mechanism 2 is mounted with a guide rail rod 12 via a pair of brackets 2. Specifically, the lower support plate 3 of the pipe clamp mechanism 2 is mounted with bracket 2, and the guide rail rod 12 is slidably mounted with a moving block 9. Both the moving block 17 and the moving block 9 are provided with a sliding groove 3 20 that mates with the cylindrical rod 27. The cylindrical rods 27 on both sides are slidably mounted in the sliding groove 3 20 on the corresponding side. Specifically, the cylindrical rod 27 on the pipe clamp mechanism 1 is mounted in the sliding groove 3 20 on the moving block 17, and the cylindrical rod 27 on the pipe clamp mechanism 2 is mounted in the sliding groove 3 20 on the moving block 2 9.

[0056] A pair of guide grooves 33 are provided on the first movable block 17, and a pair of guide rods 21 are provided on the corresponding second movable block 9. The guide rods 21 are slidably disposed in the corresponding guide grooves 33.

[0057] A second motor 19 is provided on one side of the pipe clamping mechanism 1. Specifically, the second motor 19 is located on the corresponding side of the vertical rod 16. The corresponding end of the second lead screw 18 is located on the output end of the second motor 19. The second motor 19 drives the second lead screw 18 to rotate, which in turn drives the first moving block 17 and the second moving block 9 to slide, thereby causing the two driving parts 2 to act, thus realizing the clamping or loosening of the pipe by the first pipe clamping mechanism and the second pipe clamping mechanism.

[0058] A support plate is provided on one side of the base 1 near the second pipe clamping mechanism. A lead screw 11 is rotatably mounted on the support plate. A motor 15 is provided on the corresponding first pipe clamping mechanism. Specifically, the motor 15 is located on the side of the vertical rod 16 of the first pipe clamping mechanism. The free end of the lead screw 11 is located on the output end of the motor 15. A lead screw slider 10 is provided around the lead screw 11. One side of the lead screw slider 10 is located on the second pipe clamping mechanism. Specifically, the lead screw slider 10 is located on the vertical rod 16 of the second pipe clamping mechanism.

[0059] Motor 315 drives lead screw 311 to rotate, which in turn drives pipe clamp mechanism 2 to slide, thus facilitating the clamping of the pipe.

[0060] The lower surface of the base 1 is provided with several casters, and a push handle is provided on one side of the base 1.

[0061] The usage method is as follows:

[0062] S1. Assuming there are two sets of pipes that need to be welded and installed, first lower the pipes on both sides through the pre-embedded holes on both sides of the floor slab until the pipe ends on both sides are abutting against the two pipe ends on the lower side.

[0063] S2. Push this device to the vicinity of the pipeline, and then use motor 315 to bring pipe clamp mechanism 2 closer to pipe clamp mechanism 1 until the pipe clamps on both sides can enter between the two pipelines. Then push this device so that the pipe clamps on both sides are aligned with the corresponding pipes. Then use motor 315 to slide pipe clamp mechanism 2 and adjust this device until the pipes on both sides are in the corresponding pipe clamps. At this time, the upper pipe is in the upper pipe clamp and the lower pipe is in the lower pipe clamp.

[0064] S3. The pipe clamp is clamped by the motor 19. Since the center lines of the upper and lower pipe clamps are collinear, the center lines of the upper and lower pipes are also collinear after clamping.

[0065] S4. Since clamping may cause displacement of the pipe ports on the upper and lower sides and prevent them from contacting, motor 8 can be used to drive the upper pipe clamp to move the upper pipe downward until the pipe ports on the upper and lower sides contact each other.

[0066] S5. Start welding. After welding the outer half circle, the pipe can be easily rotated due to the setting of roller 1 31 and roller 2 32, so that the unwelded part is exposed.

[0067] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
