[0002] A flow pipe expansion joint is a device used to connect pipes, valves, pumps, and other equipment. It can freely expand and contract within a certain range, compensating for pipe displacement caused by temperature changes. This feature allows the expansion joint to adapt to changes in pipe displacement, thereby protecting the normal operation of the pipe and equipment. Conventional technology requires a surface painting process before shipment. During this painting process, the joint is often fixed with a double-sided clamp, resulting in poor fixing effect. Furthermore, the clamping surface of the expansion joint cannot be painted, requiring multiple processing steps.

[0003] For example, the authorized patent document with application number CN201921065853.8 discloses an inner wall painting device for the production of three-way joints, which belongs to the field of three-way joints and solves the problem that the existing device cannot realize the rotation of the three-way joint, resulting in uneven painting; its technical features are: it includes a base, a protective cover and a nozzle, the upper part of the base is provided with a protective cover, the base and the protective cover are connected by a snap buckle, a joint placement plate is installed in the protective cover, a placement plate driving assembly is provided below the joint placement plate, a nozzle is provided above the joint placement plate, the nozzle is connected to a paint conduit, and a joint rotation assembly for rotating the joint is provided on the upper surface of the joint placement plate, and a plurality of support legs for supporting the base are fixedly installed on the lower surface of the base; the utility model is simple to operate, the three-way joint is easy to rotate, and the accuracy of painting is ensured.

[0030] The elastic member 30 includes a short plate 301, a slide rod 302 and a support spring 303. The slide rod 302 is slidably mounted inside the push block 35. The short plates 301 are fixedly mounted at both ends of the slide rod 302. The bottom of the short plate 301 is fixedly mounted on the top of the disc 31. A support spring 303 is clamped between one side of the push block 35 and the surface of the short plate 301. The interior of the support spring 303 is movably sleeved with the surface of the slide rod 302.

[0031] In this embodiment, before painting the surface of the guide pipe expansion joint, it needs to be fixed. First, the convex rod portion on the surface of the center disk 32 is moved to rotate the center disk 32. The rotation of the center disk 32 drives the hinge seat 33 to rotate accordingly. At the same time, the swing frame 34 swings and adjusts, thereby pulling the three push blocks 35 closer to each other, and the push blocks 35 slide on the slide bar 302 and stretch the support spring 303 until the joint is put on the three support rods 37. The three support rods 37 are inserted into the inner wall of the joint, so that the internal fixation of the joint will not contact the joint surface, and a support plate portion is integrally processed on the three support rods 37 to support the bottom of the joint. Under the action of the support spring 303, the three support rods 37 have the force to move away from each other, thereby fixing the joint. The paint spraying mechanism 4 is used to spray paint on the joint surface.

[0032] Two guide blocks 5 are fixedly mounted on the bottom of each of the three push blocks 35, and a guide groove 6 for the guide blocks 5 to slide is provided on the top of the disc 31;

[0033] Specifically, during the movement of the push block 35 , the guide block 5 at the bottom is driven to slide in the guide groove 6 , thereby guiding the movement of the push block 35 and preventing the push block 35 from rotating and adjusting.

[0034] The disc 31 is further provided with a driving member 7, which includes a cylinder 71, a gear ring 72, a driving gear 73, and a motor 74.

[0037] It is worth noting that the water pump 44 is started to transport the paint liquid in the box 41 to the spray plate 43 through the pipe body 42, and the paint liquid is atomized by the nozzle on the surface of the spray plate 43, so as to be coated on the joint surface.

[0038] An inclined groove is provided on the top of the workbench 1, and a filter frame 8 is embedded in the workbench 1, which is connected to the interior of the box 41;

[0039] Specifically, an inclined groove portion is opened on the top of the workbench 1, which is conducive to concentrating the sprayed paint liquid, and is connected to the filter frame 8 at the lowest point of the inclined groove portion. The filter frame 8 is connected to the box body 41 and has a recycling function. At the same time, the filter net intercepts debris.

[0040] In order to dry the joint surface after painting, two heating rods 9 are installed on the top of the inner wall of the frame 2.

[0041] Before this device is used to paint the surface of the expansion joint of the guide pipe, it needs to be fixed. First, the convex rod part on the surface of the center disk 32 is moved to rotate the center disk 32. The rotation of the center disk 32 drives the hinge seat 33 to rotate accordingly. At the same time, the swing frame 34 swings and adjusts, thereby pulling the three push blocks 35 closer to each other, and the push blocks 35 slide on the slide bar 302 and stretch the support spring 303 until the joint is put on the three support rods 37. The three support rods 37 are inserted into the inner wall of the joint, so that the internal fixation of the joint will not contact the joint surface, and a support plate part is integrally processed on the three support rods 37 to support the bottom of the joint. Under the action of the support spring 303, the three support rods 37 have the force to move away from each other, thereby fixing the joint. The paint spraying mechanism 4 is used to spray paint on the surface of the joint.
