[0025] Pipes have been widely used in fields such as ships and electronic equipment to protect the internal space of the pipes. During the production process of pipes, the quality of the pipes needs to be tested to ensure that the quality of the pipes is qualified, thereby ensuring the safety and reliability of the products.

[0026] There are many types of pipes. For ease of description, a double-wall pipe is used as an example below.

[0027] The double-walled pipe may include an outer layer pipe and an inner layer pipe. The outer layer pipe has the advantages of insulation, corrosion resistance, and wear resistance. The inner layer pipe may be sleeved inside the outer layer pipe. The inner layer pipe may extend coaxially with the outer layer pipe. The inner layer pipe has the advantages of low melting point, waterproofness, sealing, and high adhesion.

[0028] Double-walled pipes can meet the requirements of waterproof, leak-proof, and anti-corrosion protection for the wiring of ships and electronic equipment. Double-walled pipes can be used in scenarios such as waterproof wiring of water pumps and submersible pumps. Double-walled pipes can also be used in scenarios such as ship gas transportation. Therefore, it is necessary to test the air tightness, smoothness, and other properties of the side walls of double-walled pipes.

[0029] Figure 1 It is a structural schematic diagram of the pipeline testing tooling of the utility model.

[0030] See also Figure 1 For ease of understanding and description, the state of the pipeline inspection tooling when in use is taken as a reference, and the up and down directions of the pipeline inspection tooling are taken as the up and down directions below.

The limiting structure 300 may include a movable bracket 310, a rotating plate 320 and a limiting assembly 330. The movable bracket 310 is movably arranged on the base 100 so as to be able to move toward the end of the pipeline. The rotating plate 320 is rotatably arranged on the movable bracket 310, and the rotating axis of the rotating plate 320 is parallel to the axial direction of the pipeline. The limiting assembly 330 can be arranged on a side surface of the rotating plate 320 facing the pipeline, and the limiting assembly 330 is used to support and limit the end of the pipeline. Among them, the rotating plate 320 rotates to be able to drive the pipeline to rotate along the rotating axis of the rotating plate 320.

[0032] When the pipeline is undergoing quality inspection, the pipeline is moved onto the base 100, and then the movable bracket 310 is moved toward the end of the pipeline. After the movable bracket 310 moves to the end of the pipeline, the limit assembly 330 abuts against and limits the end of the pipeline. When it is necessary to monitor the circumferential quality of the pipeline, the pipeline can be driven to rotate by the rotating plate 320. On the one hand, the rotating plate 320 drives the pipeline to rotate, which can effectively improve the rotation efficiency of the pipeline, thereby improving the inspection efficiency; on the other hand, there is no need for the staff to manually rotate the pipeline, which improves the safety during the pipeline inspection process.

[0084] In another embodiment, the support structure 600 is located on the upper side of the moving groove 110 to facilitate alignment and support of the pipeline.

[0085] In some embodiments, the support structure 600 may further include an elastic member 340. The elastic member 340 is disposed on a side wall of the support plate 630 facing the pipeline. The elastic member 340 can support and buffer the pipeline to increase the friction between the support plate 630 and the pipeline and improve the support stability.

[0086] In other embodiments, the limiting assembly 330 may also include an elastic member 340. The elastic member 340 is disposed on a side wall of the clamping plate 331 facing the center of the plurality of clamping plates 331, and the elastic member 340 can be pressed on the pipe. On the one hand, the elastic member 340 can support and buffer the pipe to increase the friction between the support plate 630 and the pipe, and improve the stability of the pipe clamping. On the other hand, the elastic member 340 can protect the peripheral side wall of the pipe, thereby preventing the clamping plate 331 from damaging the peripheral side wall of the pipe when driving the pipe to rotate.

[0087] In some other embodiments, the elastic member 340 may include a plurality of elastic protrusions, which are arranged at intervals.

[0088] See also Figures 1 to 3 In this embodiment, the tooling may further include a detection device (not shown in the figure) to perform quality inspection on the pipeline. The detection device may include a pipe wall detector, a leak detector, an air tightness detector, and the like.

[0089] See also Figures 1 to 3 In the present invention, when the pipeline is to be inspected for quality, the pipeline is moved onto the support structure 600, and the outer wall of the pipeline is supported on the support plate 630. Then the moving motor 220 drives the moving screw 210 to rotate, and the moving screw 210 drives the moving bracket 310 to move toward the end of the pipeline.

[0090] When the limiting structure 300 moves to the end of the pipe, the clamping motor 420 drives the clamping screw 410 to rotate, and the clamping screw 410 drives the multiple clamping plates 331 to move toward the center of the clamping plates 331 to respectively support and limit the outer peripheral wall of the pipe.

[0091] After the limiting structure 300 clamps and limits the pipeline, the telescopic end of the first telescopic member 510 and the nozzle 520 can extend into the pipeline to clean the pipeline. After the pipeline is cleaned, the telescopic end of the first telescopic member 510 and the nozzle 520 are moved out of the pipeline.

[0092] Finally, the second telescopic member 620 is retracted, and the support plate 630 is away from the pipeline. Then, the rotating plate 320 drives the pipeline to rotate through the limiting assembly 330, so that the quality of the pipeline can be detected by the detection device.

[0093] See also Figures 1 to 3In this embodiment, the tooling may include two limiting structures 300. The two limiting structures 300 are arranged at intervals so as to be able to move toward or away from each other, so that the two limiting structures 300 can clamp the two ends of the pipe respectively.

[0094] The two limiting structures 300 are transmission-connected to the mobile driving assembly so that the two limiting structures 300 can move toward or away from each other, so that the two limiting structures 300 respectively limit the two ends of the pipeline, thereby facilitating the rotation of the pipeline and also facilitating the staff to detect the quality of the pipeline.

[0095] In some embodiments, the sliding sleeves 313 on the two moving plates 311 are sleeved on the moving screw rod 210, so that the moving screw rod 210 can drive the two limiting structures 300 to move toward and away from each other. In other embodiments, the moving screw rod 210 is a positive and negative thread screw rod.

[0096] In some other embodiments, there are two cleaning structures 500 corresponding to the two limiting structures 300, so as to be able to clean the inner wall of the pipeline from both ends of the pipeline respectively.

[0097] In some embodiments, the support structure 600 is located between the two limiting structures 300 to support the middle portion of the pipeline.

[0098] See also Figures 1 to 3 In the present invention, when the pipeline is to be inspected for quality, the pipeline is moved onto the support structure 600, and the outer wall of the pipeline is supported on the support plate 630. Then the moving motor 220 drives the moving screw 210 to rotate, and the moving screw 210 drives the two moving brackets 310 to move toward the two ends of the pipeline respectively.

[0099] When the two limiting structures 300 move to the two ends of the pipe respectively, the clamping motor 420 drives the clamping screw 410 to rotate, and the clamping screw 410 drives the multiple clamping plates 331 to move toward the center of the clamping plate 331 to respectively support and limit the outer peripheral wall of the pipe.

[0100] After the two limiting structures 300 clamp and limit the two ends of the pipeline, the telescopic ends of the first telescopic members 510 and the nozzles 520 on the two movable plates 311 can clean the pipeline.

[0101] Finally, the second telescopic member 620 is retracted, and the support plate 630 is away from the pipeline. Then, the two rotating plates 320 drive the pipeline to rotate, so that the quality of the pipeline can be detected by the detection device.
