Description

Technical Field

[0001] This application relates to the field of pipe assembly, and in particular to a modular pipe elbow assembly platform. Background Technology

[0002] Pipelines are devices made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. They are an important part of transportation equipment. During the installation of pipelines, bends are often used to change the direction of fluid in order to reduce the accumulation of substances in the pipeline. Therefore, the assembly and installation of bends is also an important part.

[0003] Currently, the installation of bends involves welding the straight pipes together with the bends. When connecting the straight and bends, they are usually supported before being joined. However, when the straight and bends are brought close together for connection, the horizontal position between them can easily be altered due to shaking during transportation, which reduces the accuracy of the connection and affects the subsequent welding precision. Therefore, this method needs to be improved. Summary of the Invention

[0004] To improve the installation accuracy of pipe bends, this application provides a modular pipe elbow assembly platform.

[0005] The modular pipe elbow assembly platform provided in this application adopts the following technical solution:

[0006] A modular pipe elbow assembly platform includes two assembly platforms, one installation bend, and two installation connecting pipes. A first clamp is fitted onto the outer wall of the installation connecting pipe, and a second clamp is fitted onto the outer wall of the installation bend. The two installation connecting pipes are symmetrically arranged at both ends of the installation bend so that each installation connecting pipe corresponds to one assembly platform. Each assembly platform has a sliding groove facing the corresponding installation connecting pipe. Each assembly platform is provided with a sliding component corresponding to the installation connecting pipe, and the sliding component is inserted into the corresponding sliding groove. The sliding component drives the corresponding installation connecting pipe to slide along the length of the sliding groove. An installation block connected to the second clamp is provided in the sliding groove of one of the assembly platforms.

[0007] By adopting the above technical solution, after the sliding component is started, the sliding component drives the installation connecting pipe to slide along the corresponding sliding groove, so that the installation connecting pipe is close to the installation mounting pipe. The sliding component also keeps the installation connecting pipe parallel to the assembly platform, thereby improving the accuracy of welding the installation connecting pipe and the installation bend, and thus improving the connection accuracy of the installation bend and the installation connecting pipe.

[0008] Preferably, the sliding assembly includes a sliding block, a drive motor, and a drive screw. The drive motor is connected to the inner wall of the sliding groove, one end of the drive screw is connected to the coupling of the drive motor of the sliding groove, the sliding block is sleeved on the drive screw, the outer wall of the sliding block is in contact with the inner wall of the sliding groove, and a rotating assembly is provided at the sliding block, the rotating assembly driving the first clamp to rotate.

[0009] By adopting the above technical solution, after the drive motor is started, the drive screw rotates, and the drive screw drives the sliding block to move along the length direction of the sliding groove, thereby causing the sliding block to drive the installation connecting pipe to move and approach the installation bend, improving the connection stability between the installation bend and the installation connecting pipe; the rotating component can drive the first clamp to rotate, after the installation connecting pipe and the installation bend are welded.

[0010] Preferably, the rotating assembly includes a rotating motor, a rotating rod, a rotating gear, a rotating gear ring, and a rotating block. The sliding block is provided with a rotating groove, and the rotating block is inserted into the rotating groove. The sliding block is provided with an operating cavity communicating with the rotating groove. The rotating motor is connected to the inner wall of the rotating groove. One end of the rotating rod is connected to the end wall of the rotating motor, and the other end of the rotating rod extends into the rotating groove and is connected to the rotating gear. The rotating gear ring meshes with the rotating gear, and the rotating block is connected to the rotating gear ring. The first clamp is connected to the rotating block.

[0011] By adopting the above technical solution, after the rotating motor is started, the rotating motor drives the rotating rod to rotate, and the rotating gear rotates synchronously, so that the rotating gear ring drives the rotating block to rotate. After the sliding block rotates in the sliding groove, the angle of the installation connecting pipe changes. After a part of the installation connecting pipe and the installation bend are welded, the rotating assembly is started to facilitate the welding of the remaining parts of the installation connecting pipe and the installation bend.

[0012] Preferably, the side wall of the rotating groove is provided with a limiting groove, the side wall of the rotating block is provided with a positioning plate inserted into the limiting groove, the positioning block can slide along the length direction of the limiting groove, the positioning block is provided with a snap-fit ​​block, and the limiting groove is provided with a snap-fit ​​groove for the snap-fit ​​block to be inserted.

[0013] By adopting the above technical solution, when the rotating block rotates, the positioning plate slides in the limiting groove. The positioning plate can slide in the limiting groove, thereby improving the stability of the rotating block when rotating and reducing the occurrence of the installation connecting pipe falling off when the rotating component is operated to rotate the rotating block. At the same time, the snap-fit ​​block is inserted into the snap-fit ​​groove to reduce the occurrence of the rotating block rotating too much, further improving the stability of the installation connecting pipe.

[0014] Preferably, the sliding block is provided with an insertion slot communicating with the operating cavity, and an insertion plate is slidably connected in the insertion slot. The insertion plate is provided with a locking rod, and the outer wall of the rotating rod is provided with a limiting plate. The surface of the limiting plate is provided with a limiting hole for the locking rod to be inserted, and the outer wall of the locking rod is adapted to the inner wall of the limiting hole.

[0015] By adopting the above technical solution, after the rotating component drives the rotating rod to the position required for installing the connecting pipe, the sliding plug plate moves close to the operating cavity and the locking rod is inserted into the limiting hole on the surface of the limiting plate. This can reduce the occurrence of the phenomenon that the accuracy between the installing connecting pipe and the installing bend pipe decreases due to the rotation of the rotating plate during the subsequent welding process.

[0016] Preferably, the surface of the sliding block is provided with a stabilizing groove that communicates with the insertion groove, a positioning rod is inserted into the stabilizing groove, and the surface of the plug plate is provided with a locking groove for the positioning rod to be inserted.

[0017] By adopting the above technical solution, after the plug plate slides, the positioning rod is inserted into the stabilizing groove, and after the positioning rod slides, it is inserted into the locking groove on the surface of the plug plate. This allows the positioning rod to limit the plug plate, reducing the occurrence of plug plate sliding due to vibration generated during welding in subsequent welding processes. This further improves the stability of the installation connecting pipe and the installation bend during welding, and effectively improves the accuracy of welding between the installation connecting pipe and the installation bend.

[0018] Preferably, the side wall of the sliding block is provided with a fixing block, and a fixing bolt that is threadedly connected to the assembly platform is inserted in the fixing block.

[0019] By adopting the above technical solution, after the position of the installation connecting pipe is fixed, the fixing bolt is passed through the fixing block and threadedly connected to the assembly platform, thereby fixing the position of the sliding block and effectively improving the stability of the installation connecting pipe after installation.

[0020] Preferably, the mounting block includes a receiving block and a lifting block. The mounting block is provided with a lifting groove, the lifting block is inserted into the lifting groove, a lifting motor is provided in the lifting groove, the coupling of the lifting motor is provided with a lifting screw, the lifting block is sleeved on the lifting screw, and the second clamp is connected to the lifting block.

[0021] By adopting the above technical solution, after the lifting motor is started, the lifting block drives the second clamp to move along the length of the lifting groove, so as to adjust the height of the installation bend and to position the bend between the concealed bend and the installation connecting pipe, thereby improving the stability between the installation bend and the installation connecting pipe.

[0022] Preferably, the assembly platform is equipped with rotating wheels.

[0023] By adopting the above technical solution, the assembly platform can be moved by pushing the rotating wheel, so as to move the assembled bend, thereby improving the mobility of the conveying platform.

[0024] Preferably, the assembly platform is equipped with a measuring level and a platform positioning ruler.

[0025] By adopting the above technical solution, the measuring level can measure the horizontal and vertical positions of the installed connecting pipe, thereby facilitating timely adjustment of the position of the installed connecting pipe and effectively improving the accuracy between the installed connecting pipe and the installed bend.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Install the mounting connecting pipe onto the sliding assembly. After determining the angle of the mounting connecting pipe, clamp the first clamp onto the mounting connecting pipe and connect it to the sliding assembly. Then, manipulate the sliding assembly to move it closer to the mounting bend, so that the mounting connecting pipe can be precisely positioned close to the mounting bend. This not only improves the convenience of moving the mounting connecting pipe but also improves the welding accuracy between the mounting connecting pipe and the mounting bend during subsequent welding processes.

[0028] 2. A rotating component is installed in the sliding block. After the rotating motor is started, the rotating rod rotates, which causes the rotating gear to rotate. The rotating gear drives the rotating gear ring to rotate, and the rotating block follows the rotating gear ring to rotate. This causes the first clamp to drive the installation connecting pipe to rotate. After the installation connecting pipe is welded to the installation bend, the rotating component is operated to make the installation connecting pipe rotate, which facilitates the welding of the remaining parts of the installation connecting pipe and the installation bend, effectively improving the convenience of welding between the installation connecting pipe and the installation bend.

[0029] 3. The assembly platform is equipped with a testing level, which can detect the angle of the installation connecting pipe or the installation bend, thereby facilitating timely adjustment of the angle between the installation connecting pipe and the installation bend, further improving the connection accuracy between the installation connecting pipe and the installation bend, and thus improving the connection stability between the installation connecting pipe and the installation bend.

The sliding component 4 can drive the corresponding installation connecting pipe 3 to slide along the length direction of the sliding groove 11, so that the installation connecting pipe 3 can approach the installation bend 2.

[0039] Reference Figure 2 and Figure 3 The sliding assembly 4 includes a sliding block 41, a drive motor 42, and a drive screw 43.

The side wall of the sliding block 41 fits snugly with the inner wall of the sliding groove 11. The sliding block 41 is threadedly connected to the drive screw 43. After the drive motor 42 is started, the drive screw 43 rotates, and the sliding block 41 can move along the length direction of the sliding groove 11 and approach the mounting bend 2.

[0040] Reference Figure 3 , Figure 4 and Figure 5A rotating assembly 5 is installed at the sliding block 41. The rotating assembly 5 is connected to the first clamp 31. After the sliding block 41 moves, the first clamp 31 moves synchronously with the sliding block 41, thereby bringing the mounting connecting pipe 3 closer to the mounting bend 2. The rotating assembly 5 includes a rotating motor 51, a rotating rod 52, a rotating gear 53, a rotating gear ring 54, and a rotating block 55. A rotating groove 44 is formed on the upper surface of the sliding block 41. The rotating groove 44 is an arc-shaped groove. The rotating block 55 is inserted into the rotating groove 44, and the side wall of the rotating block 55 is in contact with the inner wall of the rotating groove 44. An operating cavity 45 is formed at the upper end of the sliding block 41. The operating cavity 45 communicates with the rotating groove 44. The rotating motor 51 is far from the operating cavity 45. One end of the rotating block 52 is fixedly connected to the rotating groove 44 by screws. One end of the rotating rod 52 is welded and fixed to the coupling of the rotating motor 51. The other end of the rotating rod 52 extends into the rotating groove 44 and is welded and fixed to the shaft of the rotating gear 53. The rotating gear 53 is located in the rotating groove 44. The outer wall of the rotating block 55 is fixedly connected to the rotating gear ring 54 by screws. The rotating gear 53 and the rotating gear ring 54 mesh with each other. The first clamp 31 is fixedly connected to the side of the rotating block 55 away from the rotating gear ring 54 by screws. After the rotating motor 51 is started, the rotating gear 53 drives the rotating gear ring 54 to rotate, thereby causing the first clamp 31 to drive the mounting connecting pipe 3 to rotate circumferentially along the mounting connecting pipe 3.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The side wall of the rotating block 55 is integrally formed with a positioning plate 551. The sliding block 41 is located on the side wall of the limiting groove 441, which has a limiting groove 441. The positioning plate 551 is inserted into the limiting groove 441. The limiting groove 441 is opened along the rotation direction of the rotating block 55. The side wall of the positioning plate 551 and the inner wall of the limiting groove 441 are adapted and fitted together. The inner wall of the limiting groove 441 has a snap-fit ​​groove 442. The positioning plate 551 is located at the center of its length direction with a snap-fit ​​block 552. The snap-fit ​​block 552 is inserted into the snap-fit ​​groove 442. The outer wall of the snap-fit ​​block 552 is fitted with the outer wall of the snap-fit ​​groove 442. The snap-fit ​​groove 442 is opened along the length direction of the limiting groove 441. The limiting groove 441 is a through groove, while the snap-fit ​​groove 442 is not a through groove. The setting of the snap-fit ​​block 552 and the positioning plate 551 effectively improves the stability of the rotating block 55 during rotation.

[0042] Reference Figure 3 , Figure 4 and Figure 5The sliding block 41 has an insertion slot 46. In this embodiment, each sliding block 41 has two insertion slots 46. The insertion slots 46 are opened along the width direction of the sliding block 41 and are located at different horizontal planes. The two insertion slots 46 are parallel to each other.

Limiting holes 522 are opened through the surface of limiting plate 521 along its thickness direction. When rotating rod 52 rotates to the required position, sliding plug plate 47 is slidable. The locking rod 471 of plug plate 47 is inserted into the limiting hole 522 of limiting plate 521. The outer wall of locking rod 471 and the inner wall of limiting hole 522 are adapted to each other, thereby reducing the phenomenon of rotating rod 52 rotating when welding installation connecting pipe 3 and installation bend 2, and improving the stability when welding installation bend 2 and installation connecting rod.

The positioning rod 49 is a cylindrical rod, and the outer wall of the positioning rod 49 fits against the inner wall of the stabilizing groove 48. The surface of the plug-in plate 47 is provided with a locking groove 472. After the plug-in plate 47 slides along the insertion groove 46 and the locking rod 471 is inserted into the limiting hole 522, the positioning rod 49 is inserted into the stabilizing groove 48, so that the positioning rod 49 is inserted into the locking groove 472 of the plug-in plate 47, which further improves the stability of the plug-in plate 47.

[0044] Reference Figure 3 The sidewall of the sliding block 41 is integrally formed with a fixing block 411. The fixing block 411 is a rectangular block. Each sliding block 41 has two fixing blocks 411. The fixing blocks 411 are located on both sides of the length direction of the sliding block 41. Fixing bolts 412 are inserted into the surface of the fixing blocks 411. After the position of the sliding block 41 is fixed, the fixing bolts 412 are passed through the sliding block 41 and the fixing bolts 412 are threaded to the assembly platform 1, thereby effectively improving the stability of the sliding block 41.

[0045] Reference Figure 2 , Figure 4 and Figure 5One of the assembly platforms 1 has a sliding groove 11 in which an installation block 6 is inserted. The installation block 6 can slide along the length of the sliding groove 11. The lower end of the installation block 6 is inserted into the sliding groove 11. The outer wall of the installation block 6 is in contact with the inner wall of the sliding groove 11. It includes a receiving block 61 and a lifting block 62. The upper surface of the installation block 6 has a lifting groove 63 along its height direction. The lifting block 62 is inserted into the lifting groove 63.

The lifting block 62 is sleeved on the lifting screw 65. The lifting block 62 and the lifting screw 65 are threadedly matched. The side wall of the lifting block 62 is in contact with the inner wall of the lifting groove 63. The second clamp 21 is fixedly connected to the upper surface of the lifting block 62 by screws. The position of the lifting block 62 is adjusted by the lifting motor 64 to facilitate the adjustment of the horizontal position of the installation bend 2 and the installation connecting pipe 3.

[0046] Reference Figure 1 and Figure 2 The side of the assembly platform 1 facing away from the sliding groove 11 is connected to a rotating wheel 12 via a rotating rod 52. A measuring level 13 is fixedly connected to the connection point of the two assembly platforms 1 by screws. In this embodiment, the measuring level 13 is an infrared level, which can measure the distance and position between the installation connecting pipe 3 and the installation bend 2. A platform positioning ruler 14 is embedded in the side wall of the assembly platform 1. The platform positioning ruler 14 is engraved with scale, which can further facilitate the measurement of the distance between the installation bend 2 and the installation connecting pipe 3.

[0047] The implementation principle of the modular pipe elbow assembly platform in this application embodiment is as follows:

[0048] First, install the connecting pipe 3 according to the construction requirements. Fix the first clamp 31 to the sliding block 41 with screws. Then, snap the connecting pipe 3 into the first clamp 31. After confirming the angle of the connecting pipe 3 using a level 13, connect the bend pipe 2. After fixing the second clamp 21 to the lifting block 62, snap the bend pipe 2 into the second clamp 21. Adjust the horizontal position between the bend pipe 2 and the connecting pipe 3 using the lifting motor 64, and confirm the horizontal position between them using the level 13. Then, start the drive motor 42 on the assembly platform 1. After the moving screw 43 rotates, the sliding block 41 drives the mounting connecting pipe 3 to approach the mounting bend 2. When the mounting connecting pipe 3 and the mounting bend 2 approach each other, the mounting bend 2 and the mounting connecting pipe 3 are welded together. After the mounting bend 2 is welded to one mounting connecting pipe 3, the drive motor 42 at another assembly platform 1 is started, so that the sliding block 41 at the other assembly platform 1 drives another mounting connecting pipe 3 to approach the mounting bend 2. Then the mounting bend 2 is welded to the other mounting connecting pipe 3. Using the assembly platform to connect the mounting bend 2 and the mounting connecting pipe 3 effectively improves the connection accuracy between the mounting bend 2 and the mounting connecting pipe 3.
