[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a pipe tightness testing device for easy fixing of workpieces, comprising several bases 1, each base 1 having an arc-shaped placement plate 2 on its top, each arc-shaped placement plate 2 having an arc-shaped cover plate 3 rotatably mounted on its top, each adjacent arc-shaped placement plate 2 being detachably connected, and each arc-shaped cover plate 3 having an arc-shaped fixing plate 4 for fixing pipes of different sizes mounted on its inner wall bottom, with the arc-shaped fixing plate 4 being mounted on the top of one end of the arc-shaped cover plate 3, and the other arc-shaped fixing plates 4 being detachably connected to the arc-shaped fixing plate 4 of one end of the arc-shaped cover plate 3. By assembling multiple arc-shaped placement plates 2, pipes of different lengths can be adapted.

[0021] In this embodiment, adjacent arc-shaped placement plates 2 are connected by a quick-disassembly structure, which can accommodate pipes of different lengths and facilitate disassembly and transportation.

[0022] The arc-shaped cover plate 3 is connected to the top of the arc-shaped placement plate 2 via a hinge or pivot. During testing, it is closed to form a sealed cavity. After testing, it can be easily opened for easy pipe placement and removal. The arc-shaped cover plate 3 has a reserved interface for injecting compressed air / water to monitor pressure changes or leaks.

[0023] One end of the arc-shaped cover plate 3 integrates a drive component at the top to control the lifting and lowering of the arc-shaped fixing plate 4 at that end. The other arc-shaped fixing plates 4 are connected in a detachable manner and move synchronously with the drive end to achieve uniform fixing of multiple pipe sections. The lifting and lowering of the arc-shaped fixing plates 4 can fix the pipe when it is thinner, thus adapting to pipes of different diameters.

[0024] According to the pipe length, the splicing base 1 and the arc-shaped placement plate 2 are connected. The pipe is placed on the arc-shaped placement plate 2, all the arc-shaped cover plates 3 are closed, the drive component is started, and all the arc-shaped fixing plates 4 are lowered synchronously. The arc-shaped surface is tightly attached to the outer wall of the pipe, avoiding local stress damage from traditional clamps. Then, the pipe is inspected. After the inspection is completed, the arc-shaped fixing plate 4 is raised, the arc-shaped cover plate 3 is opened and the pipe is taken out. The modules are disassembled and stacked for storage, saving space and facilitating transportation.

[0025] Furthermore, a drive box 6 is provided at one end of the top of the arc-shaped placement plate 2, and a first motor 7 is arranged horizontally inside the drive box 6. One end of the arc-shaped cover plate 3 is fixedly connected to the output shaft of the first motor 7.

[0026] In this embodiment, the arc-shaped placement plate 2 and the arc-shaped cover plate 3 are fitted together in a circular shape to withstand the maximum roughness.

[0027] All the arc-shaped cover plates 3 are in the open position to facilitate pipe placement. The arc-shaped fixing plate 4 is in the highest position to avoid interfering with pipe installation. After the pipe is placed, the first motor 7 drives the arc-shaped cover plate 3 to rotate until the arc-shaped cover plate 3 is in contact with the arc-shaped placement plate 2.

[0028] Furthermore, a receiving box 8 is vertically arranged on the top of one of the arc-shaped cover plates 3, and a second motor 9 is vertically arranged at the bottom of the inner cavity of the receiving box 8. The output shaft of the second motor 9 is fixedly connected to a threaded rod 10, and a threaded sleeve 11 is threadedly connected to the surface of the threaded rod 10. An L-shaped rod 12 is fixedly connected to the surface of the threaded sleeve 11, and a vertical plate 5 is fixedly connected to one end of the L-shaped rod 12. The bottom of the vertical plate 5 is fixedly connected to the upper surface of the arc-shaped fixing plate 4.

[0029] In this embodiment, a pressure sensor is provided at the bottom of the arc-shaped fixing plate 4.

[0030] After the pipe is placed, the PLC sends a command to the second motor 9. The second motor 9 drives the threaded rod 10 to rotate, and the threaded sleeve 11 drives the L-shaped rod 12 and the vertical plate 5 to descend at a constant speed. When the pressure sensor detects that the contact force reaches the preset threshold, the second motor 9 stops and locks.

[0031] Furthermore, each of the vertical plates 5 has several first connecting rods 17 and second connecting rods 19 on both sides. Each of the first connecting rods 17 has a connecting block 18 at one end. Each of the second connecting rods 19 has a groove 20 at one end that matches the connecting block 18. Each connecting block 18 has a second threaded groove 21 on its surface and below the groove 20. It can be fixed by screwing a fixing bolt 22 into the second threaded groove 21.

[0032] In this embodiment, when multiple vertical plates 5 need to be connected, the connecting block 18 of the first connecting rod 17 is inserted into the groove 20 in the second connecting rod 19. Then, by screwing the fixing bolt 22 into the second threaded groove 21, two adjacent vertical plates 5 can be fixed. The driving component at one end can drive one vertical plate 5 to rise and fall, thereby driving the arc-shaped fixing plate 4 at the bottom of multiple vertical plates 5 to fall until it is attached and fixed to the pipe.

[0033] The first connecting rod 17 and the second connecting rod 19 of the vertical plate 5 are located at the top of both ends of the vertical plate 5. When the first connecting rod 17 and the second connecting rod 19 are in contact with the arc-shaped cover plate 3, when the plate is moved to the lowest end, the arc-shaped fixing plate 4 is in contact with the bottom of the arc-shaped placement plate 2.

[0034] Furthermore, each of the arc-shaped cover plates 3 has a limiting rod 13 on one side wall, and each of the arc-shaped cover plates 3 has an elongated groove 14 adapted to the limiting rod 13 on the other side wall. Each limiting rod 13 has a plurality of first threaded grooves 15 on its surface that correspond to the elongated groove 14. The rods are fixed by screwing positioning bolts 16 into the first threaded grooves 15.

[0035] In this embodiment, when it is necessary to fix a long pipe, multiple arc-shaped placement plates 2 are first placed on the same plane. Then, by inserting the limiting rod 13 on the arc-shaped cover plate 3 into the long groove 14 and screwing the positioning bolt 16 into the first threaded groove 15, multiple arc-shaped placement plates 2 can be connected. This can adapt to pipes of different lengths and improve the versatility during use.

[0036] Furthermore, the vertical plates 5 at both ends are provided with a first connecting rod 17 and a second connecting rod 19 only at their inner ends, and the arc-shaped cover plates 3 at both ends are provided with a limit rod 13 and a long groove 14 only at their inner ends.

[0037] In this embodiment, only the inner first connecting rod 17 and the second connecting rod 19 are retained in the vertical plates 5 at both ends, and the connecting structure on the outer side is eliminated, simplifying the end face design.

[0038] The arc-shaped cover plates 3 at both ends are equipped with limiting rods 13 and long grooves 14 only on the inner side, and the outer side adopts a smooth transition design to reduce space occupation.

[0039] The working principle and usage process of this utility model are as follows: After the utility model is installed, the base 1 and the arc-shaped placement plate 2 are spliced ​​according to the pipe length. The pipe is placed on the arc-shaped placement plate 2, all the arc-shaped cover plates 3 are closed, the drive component is started, and all the arc-shaped fixing plates 4 are lowered synchronously. The arc-shaped surface is tightly attached to the outer wall of the pipe, avoiding local stress damage from traditional clamps. Then, the pipe is inspected. After the inspection is completed, the arc-shaped fixing plate 4 is raised, the arc-shaped cover plate 3 is opened and the pipe is taken out. The modules are disassembled and stacked for storage, saving space and facilitating transportation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
