Furthermore, workers can flexibly adjust the position of the operating lever based on on-site spatial conditions, avoiding unnecessary impact and vibration on the piping system during disassembly and assembly, thereby ensuring the safety of related equipment.

[0026] The pipeline disassembly and assembly device provided by this application will be described in detail below with reference to specific embodiments.

[0027] refer to Figure 1 and Figure 2 The present invention provides a pipeline assembly and disassembly device comprising a universal bearing 100, an operating device 200, an adjusting device 300, a first clamping member 400, and a second clamping member 500. The first clamping member 400 is fixedly connected to the universal bearing 100 and is used to clamp a first target object 10; the second clamping member 500 is fixedly connected to the adjusting device 300 and is used to clamp a second target object 20.

[0028] The universal bearing 100 includes a bearing seat 110 and a spherical inner ring 120 located inside the bearing seat 110 and movably connected to the bearing seat 110. When the spherical inner ring 120 is fixed, the bearing seat 100 can rotate 360 ​​degrees around the center of the spherical inner ring 120.

[0029] The first clamping member 400 is fixedly connected to the spherical inner ring 120, and the operating device 200 and the adjusting device 300 are fixedly connected to the outer wall of the bearing seat 110. The operating device 200 is configured to drive the bearing seat 110 to move relative to the spherical inner ring 120, thereby driving the adjusting device 300 to rotate around the spherical inner ring 120, and driving the second clamping member 500 to move relative to the first holding member 400 to align the second target 20 with the first target 10. The adjusting device 300 is configured to move the second clamping member 500 toward or away from the first clamping member 400 to move the second target 20 closer to or farther away from the first target 10.

[0030] When the pipelines need to be installed, the first and second pipelines are clamped by the first clamping member 400 and the second clamping member 500, respectively, as the first target 10 and the second target 20. The first pipeline and the first clamping member 400 are fixed in position. By operating the operating device 200, the bearing seat 110 is rotated about the spherical inner ring 120, thereby driving the adjustment device 300 to rotate about the spherical inner ring 120, so that the second pipeline is aligned with the first pipeline. Subsequently, the adjustment device 300 drives the second clamping member 500 toward the first clamping member 400, thereby bringing the second pipeline closer to the first pipeline, achieving the connection requirement. When the pipelines need to be disassembled, the first and second pipelines are clamped by the first clamping member 400 and the second clamping member 500, respectively, as the first target 10 and the second target 20. The adjustment device 300 is used to move the second clamping member 500 away from the first clamping member 400, thereby moving the second pipeline away from the first pipeline, completing the disassembly.

[0031] In some embodiments, the universal bearing 100 is a spherical plain bearing.

[0032] In some embodiments, the spherical inner ring 120 is connected to the first clamping member 400 via a connecting shaft 600 . The connecting shaft 600 includes a first connecting portion 610 , a second connecting portion 630 , and a middle portion 620 located between the first connecting portion 610 and the second connecting portion 630 .

[0033] In some embodiments, the first connecting portion 610 is located on a side of the spherical inner ring 120 close to the first clamping member 400 and is fixedly connected to the first clamping member 400 .

[0035] In some embodiments, the second connecting portion 630 extends beyond the spherical inner ring 120 and is threaded, being fixedly connected to the spherical inner ring 120 via a nut 640. In some embodiments, the second connecting portion 630 is further sleeved with a washer 650, which is disposed between the nut 640 and the bearing seat 110.

[0036] In some embodiments, the operating device 200 includes an operating rod 210, and a first end of the operating rod 210 is fixedly connected to the outer wall of the bearing seat 110. In some embodiments, the operating rod 210 is welded to the outer wall of the bearing seat 110.

[0037] In some embodiments, the angle between the operating rod 210 and the outer wall of the bearing seat 110 is 110° to 130°, for example, 110°, 120° or 130°. It should be noted that the angle refers to the angle between the axial direction of the operating rod 210 and the bottom surface of the bearing seat 110. When the bearing seat 110 is set horizontally, the operating rod 210 extends toward the ground, which is convenient for workers to operate the operating rod 210 while standing on the ground, reducing or avoiding the use of ladders or auxiliary platforms when the installation height is higher than the height of the human body, making it easier for workers to exert force while also avoiding the risk of workers falling from ladders or auxiliary platforms.

[0038] In some embodiments, the operating device 200 further includes an operating handle 220, which is disposed at the second end of the operating rod 210 and fixedly connected to the operating rod 210. In some embodiments, the operating handle 220 is sleeved onto the operating rod 210.

[0039] In some embodiments, the material of the operating handle 220 includes rubber.

[0040] The staff can hold the operating handle 220 to operate the operating rod 210, driving the bearing seat 110 to rotate around the spherical inner ring 120, and then driving the adjustment device 300 connected to the bearing seat 110 to rotate around the spherical inner ring 120. The second clamping member 500 drives the second target object 20 to move under the drive of the adjustment device 300, so that the second target object 20 is aligned with the first target object 10.

[0041] In some embodiments, the adjustment device 300 includes a slide rail 310, a slider 320, and a driving member 330. The first end of the slide rail 310 is connected to the outer wall of the bearing seat 110. The slider 320 is disposed at the second end of the slide rail 310, fixedly connected to the second clamping member 500, and movably connected to the slide rail 310. The driving member 330 is configured to drive the slider 320 to move along the slide rail 310 toward or away from the first end of the slide rail 310.

[0042] In some embodiments, the slide rail 310 includes a first slide rail 311 and a second slide rail 312, the first slide rail 311 is located on the side of the bearing seat 110 close to the second clamping member, the first slide rail 311 includes an integrally connected first connecting portion 311a and a first parallel portion 311b, the first connecting portion 311a is fixedly connected to the outer wall of the bearing seat 110, and the first parallel portion 311b is slidably connected to the slider 320; the second slide rail 312 is located on the side of the bearing seat 110 away from the second clamping member 500, the second slide rail 312 includes an integrally connected second connecting portion 312a and a second parallel portion 312b, the second connecting portion 312a is fixedly connected to the outer wall of the bearing seat 110, the second parallel portion 312b is movably connected to the slider 320, and the second parallel portion 312b is parallel to the first parallel portion 311b.

[0043] In some embodiments, the slider 320 is provided with two first through holes 321 passing through the slider, and the first through holes 321 respectively match the first parallel portion 311b and the second parallel portion 312b, so as to enable the slider 320 to slide along the first parallel portion 311b and the second parallel portion 312b.

[0044] In some embodiments, the slider 320 is further provided with a threaded hole 322 passing through the slider 320 , for threading the slider 320 to be connected to the driving member 330 . In some embodiments, the threaded hole 322 is located between the two first through holes 321 .

[0045] In some embodiments, the driving member 330 includes a traction rod 331 , a bidirectional screw rod 332 and a driving rod 333 .

[0046] The first end of the traction rod 331 is fixedly connected to the outer wall of the bearing seat 11-, and the second end of the traction rod 331 is provided with an internal threaded hole.

[0047] In some embodiments, the traction rod 331 is welded to the bearing seat 110 .

[0048] The first end of the bidirectional screw rod 332 is provided with a first thread and is threadedly connected to the internal threaded hole. The second end of the bidirectional screw rod 332 is provided with a second thread with a spiral direction opposite to that of the first thread and is threadedly connected to the slider 320. A second through hole 332a is provided between the first end and the second end of the bidirectional screw rod 332 and passes through the bidirectional screw rod 332.

[0049] refer to Figure 3, setting the second through hole 332a on the bidirectional screw rod 332 will reduce the strength of the bidirectional screw rod 332, making the bidirectional screw rod 332 prone to breakage in the area close to the second through hole 332a. Therefore, in some embodiments, the bidirectional screw rod 332 is integrally connected with a reinforcement portion 332b, and the reinforcement portion 332b is sleeved onto the bidirectional screw rod 332. The second through hole 332a simultaneously penetrates the reinforcement portion 332b and the bidirectional screw rod 332. The setting of the reinforcement portion 332b improves the strength of the bidirectional screw rod 332 and reduces the risk of breakage of the bidirectional screw rod 332.

[0050] The drive rod 333 is configured to be inserted into the second through hole 332a, driving the bidirectional screw rod 332 to rotate clockwise or counterclockwise. By rotating the drive rod 333, the bidirectional screw rod 332 can be driven to rotate clockwise or counterclockwise, thereby causing the slider 320 threadedly connected to the bidirectional screw rod 332 to move toward or away from the traction rod 331.

[0051] In some embodiments, the driving rod 333 includes a rod portion 333a and a head portion 333b located at both ends of the rod portion 333a, the rod portion 333a is inserted into the second through hole 332a, the diameter of the rod portion 333a is smaller than the diameter of the second through hole 332a, and the maximum length of the head portion 333b along the axial direction perpendicular to the rod portion 333a is greater than the diameter of the second through hole 332a, thereby preventing the driving rod 333 from falling off from the second through hole 332a.

[0052] In some embodiments, the first clamping member 400 and the second clamping member 500 are common pipe clamps. In some embodiments, the first clamping member 400 and the second clamping member 500 are disc clamps.

[0053] In some implementations, the first clamping member 400 and the second clamping member 500 are respectively welded to the connecting shaft 600 and the slider 320 .

[0054] In some embodiments, the pipeline disassembly and assembly device provided in this application is used as follows:

[0055] When the pipeline needs to be installed, the first pipeline and the second pipeline are clamped by the first clamping member 400 and the second clamping member 500 as the first target object 10 and the second target object 20 respectively. By manipulating the operating rod 210, the bearing seat 110 is driven to rotate around the spherical inner ring 120, thereby driving the adjustment device 300 to rotate around the spherical inner ring 120, so that the second pipeline is aligned with the first pipeline. Subsequently, the driving rod 333 is rotated clockwise to drive the bidirectional screw rod 332 to rotate, so that the slider 320 moves toward the traction rod 331, and then the second pipeline moves toward the first pipeline until the distance between the first pipeline and the second pipeline reaches the connection standard. Use relevant connection tools, such as snaps, to lock the first pipeline and the second pipeline.

[0056] The pipeline needs to be disassembled, and the first pipeline and the second pipeline are clamped by the first clamping member 400 and the second clamping member 500 as the first target object 10 and the second target object 20 respectively. After disassembling the buckle connecting the first pipeline and the second pipeline, the driving rod 333 is rotated counterclockwise to drive the bidirectional screw rod 332 to rotate, so that the slider 320 moves away from the traction rod 331, and then the second clamping member 500 moves away from the first clamping member 400. Driven by the second clamping member 500, the second pipeline moves away from the first pipeline, completing the disassembly of the first pipeline and the second pipeline.
