[0002] In the manufacturing industry, especially the photovoltaic industry, its vacuum equipment contains a large number of pipes, such as circulating cooling water pipes and gas pipes. The outer diameters of the pipes are different. Some circulating cooling water pipes need to install branch pipes on the main pipes. In the process of leak detection, blind plugs and pipe connectors are required, and compressed air with a certain air pressure is used as the leak detection medium. This requires that the installation of blind plugs must be firm and reliable. The current common operation method is to place the pipe directly on a plane without special fixation. The blind plug is directly fixed through the pipe connector. This poses a relatively large safety hazard, such as the blind plug being bounced off under the action of air pressure and causing accidental injury. Summary of the invention

The pipe 10 passes through the center of the gap formed by the clamping part 26, the track 22 is connected to the rotating part 21, and the clamping mechanism 15 is controlled to make a circular motion to drive the clamping claw 26 to open and close, so that the size of the hollow range is adjusted to clamp the pipe 10. A movable locking block 25 and a track 22 are also provided on the pipe locking mechanism. The clamping claw mechanism 15 limits the size of the central space of the clamping part 26 by moving the movable locking block 25 on the track 22. A rotating handle 34 and a rotating shaft 35 are also provided on the pillar 33. By shaking the rotating handle 34, the rotating shaft 35 and the blind plate 31 can perform synchronous linear horizontal motion.

[0024] As a specific embodiment, the base includes: a base 12, on which a support portion 13 is arranged, the shape of the support portion 13 is circular on the top and isosceles trapezoidal on the bottom, an extension portion 14 is arranged on the side of the support portion 13, and the clamping mechanism 15 is arranged on the extension portion 14.

[0025] As a specific embodiment, a plurality of first pads 11 are disposed below the support portion 13 , and the first pads 11 are in the shape of a right triangle.

[0026] As a specific embodiment, a fixed locking block 23 is provided on the track 22 , and the distance between the fixed locking block 23 and the movable locking block 25 is adjusted according to the diameter of the pipe 10 .

[0027] As a specific embodiment, a plurality of second pads 32 are further arranged around the axis of the blind plate 31 , and the second pads 32 are in the shape of a right triangle.

[0028] As a specific embodiment, a plurality of third pads 36 are further provided at the lower portion of the support column 33 , and the third pads 36 are in the shape of a right triangle.

[0029] As a specific embodiment, a detection table 37 is further provided under the base.

[0030] As a specific embodiment, the detection table 37 is movable.

[0031] As a specific embodiment, the clamping mechanism is also provided on the back side of the support portion 13 .

[0032] This device needs to be used in pairs, that is, when the pipeline 10 is leak-checked, blind plugging installation needs to be performed at both ends of the pipeline. This device can only work on one end face of the pipeline.

[0033] The base is used to form the main body of the device, support the device and fix it on a flat table. The first pad 11 is used to increase the strength of the support 13 .

[0034] Please refer to Figure 3 and Figure 4 The left side of the mobile locking block 25 is connected and fixed with the abutment portion 24, and the abutment portion has a connecting hole, so that the mobile locking block is connected. Like this, the linear motion of the mobile locking block 25 is utilized to be converted into the motion of the clamping portion 26 in the circumferential direction. Figure 1 It is a structural schematic diagram of the utility model when it is not in use. Figure 21 is a schematic diagram of the structure of the utility model in use, and the figure also shows that the distance between the movable locking block and the fixed locking block is shortened. In the figure: when the rotating part 21 is shaken, the rotation of the rotating part drives 22 to rotate, and then the movable locking block 25 moves closer to or away from the fixed locking block 25 on the track 22, realizing the use of the linear motion of the movable locking block 25 to convert into the movement of the clamping claw mechanism 15 in the circumferential direction.

[0035] The function of the pipe locking mechanism is to reliably fix and lock the pipe 10 to be inspected. The circular motion of the clamping part 26 is achieved by shaking the rotating part 21. The pipe can be clamped by installing three clamping parts 26. The movable locking block 25 can move on the track 22, but there are minimum and maximum limits. This limit determines the minimum and maximum diameters of the pipe that can be clamped by this mechanism. After clamping, it is locked by threaded connection.

[0036] The function of the blind plug baffle mechanism is: when installing the blind plug, the blind plug is tightly and completely fitted to the end face of the pipeline through this mechanism, so that in the process of making the blind plug and the pipeline become a whole through the pipeline connector, the blind plug and the pipeline connector are connected more firmly and reliably. When compressed air is filled, the event of the blind plug accidentally being ejected can be handled more effectively. By shaking the handle 34, the rotating shaft 35 and the blind plate 31 move synchronously in a straight line horizontally, so that the blind plate is safely fixed. The second pad 32 and the third pad 36 are provided for safety considerations to increase the strength of the support 33, so as to better handle the accidental ejection of the blind plug.

[0037] As a specific embodiment, the part of the rotating shaft 35 inside the pillar 33 is a threaded connection structure, so that the rotating shaft 35 is driven to rotate by shaking the handle 34, and the rotating shaft 35 is fixed to the blind plate 31, thereby realizing the synchronous linear horizontal movement of the rotating shaft 35 and the blind plate 31 as a whole.

[0038] The clamp mechanism has good adjustability. One set of mechanism can meet the pipe diameter of 14mm to 96mm. If a larger diameter range is required, the size of the device can be adjusted.

[0039] The blind plug baffle mechanism securely fixes the blind plate, thereby eliminating the potential safety hazard of the blind plug being bounced off during the leak detection process and improving work safety.

[0040] The second cushion ensures that the device has sufficient strength to cope with the possible unexpected situation that the blind plug is bounced off, thereby ensuring working safety.

[0041] The support portion of the utility model is in the shape of a circle on the upper side and an isosceles trapezoid on the lower side. A plurality of first pads are arranged under the support portion, which can enhance the pipe fixing effect.

[0042] By adopting the utility model, the convenience of personnel operation is greatly improved. The safety of personnel operation is more guaranteed. The reliability of the blind plug and the pipeline end face is more guaranteed. The pipeline is reliably fixed during the entire leak detection process, eliminating the safety hazard of pipeline movement. The work efficiency of pipeline leak detection is greatly improved and the working hours are reduced.

[0043] It should be clear that the present invention is not limited to the specific configurations and processes described above and shown in the figures. For the sake of simplicity, a detailed description of the known methods is omitted here. In the above embodiments, several specific steps are described and shown as examples. However, the method process of the present invention is not limited to the specific steps described and shown, and those skilled in the art can make various changes, modifications and additions, or change the order between the steps after understanding the spirit of the present invention.
