Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] First embodiment

[0027] A pressure pipeline compression resistance detection mechanism for special equipment includes a support assembly 1, an adjustment module 2, and a clamping module 3;

[0028] Among them, the clamping module 3 includes a lead screw groove 31. Two slide blocks 32 are arranged in the lead screw groove 31. The two ends of the inner side of the lead screw groove 31 are respectively movably connected to one end of a bi-directional lead screw 33. The two slide blocks 32 are respectively threadedly connected to the bi-directional lead screw 33. Two sections of threads with opposite directions are respectively arranged on the bi-directional lead screw 33. One end of the bi-directional lead screw 33 passes through one end of the lead screw groove 31, and one end of the bi-directional lead screw 33 is fixedly connected to the center of a knob 34;

[0029] The adjustment module 2 includes two square cylinders 26. The upper sides of the two slide blocks 32 are respectively fixedly connected to the corresponding square cylinders 26. Corresponding chutes 27 are respectively arranged on one side of the two square cylinders 26. Corresponding sliding shafts 25 are respectively arranged in the two chutes 27. The two sliding shafts 25 are respectively fixedly connected to the corresponding square rods 24. The two square rods 24 are respectively arranged in the corresponding square cylinders 26. The two sliding shafts 25 are respectively arranged in L-shaped grooves 28. The upper ends of the two square rods 24 are respectively fixedly connected to sealing caps 23. The air inlet end of a pressure gauge 21 passes through and is fixedly connected to the upper part of a corresponding sealing cap 23. The lower part of the corresponding sealing cap 23 is fixedly communicated with a valve 22.

[0030] The support assembly 1 includes a support plate 12. The lead screw groove 31 is arranged in the middle of the support plate 12.

[0031] Vertical plates 13 corresponding to each other are respectively fixedly connected to the upper side of the support plate 12.

[0032] The corresponding L-shaped grooves 28 are respectively arranged on the two vertical plates 13.

[0033] The upper side of the support plate 12 is fixedly connected with a U-shaped frame 11 respectively.

[0034] A groove 14 is provided in the middle of the upper side of the U-shaped frame 11.

[0035] Working principle: First, connect the valve 22 to an external air pump. When it is necessary to detect the pressure pipeline 4, place the pressure pipeline 4 in the groove 14, move the two sealing caps 23 upward. The two sealing caps 23 drive the corresponding square rods 24 to move upward along the square tubes 26 respectively. The two square rods 24 drive the corresponding sliding shafts 25 to move upward along the sliding grooves 27 respectively. At the same time, the two sliding shafts 25 move upward along the inclined grooves of the corresponding L-shaped grooves 28 respectively. When the two sealing caps 23 move to the height flush with the pressure pipeline 4, stop moving the sealing caps 23 at this time. Then, turn the knob 34. The knob 34 drives the bidirectional lead screw 33 to rotate. The bidirectional lead screw 33 drives the corresponding sliders 32 to slide towards each other. The two sliders 32 drive the corresponding square tubes 26 to move towards each other respectively, so that the two square tubes 26 drive parts such as the sliding shafts 25 and the square rods 24 to move towards each other respectively, and the two sliding shafts 25 move from the inclined groove parts of the corresponding L-shaped grooves 28 to the straight groove parts respectively. At this time, the two sealing caps 23 move closer to each other, so that the two sealing caps 23 clamp the pressure pipeline 4, forming a relatively airtight space between the pressure pipeline 4 and the two sealing caps, avoiding the phenomenon of pressure relief. Stop turning the knob 34 at this time;

[0036] Then turn on the external air pump, so that the external gas enters the valve 22 and the pressure pipeline 4 through the air pump. At the same time, observe the value of the pressure gauge 21. When the pressure gauge 21 reaches a certain value, turn off the external air pump, wait for a period of time, and observe the value of the pressure gauge 21 again. Compare the value at this time with the previous value to obtain the pressure resistance of the pressure pipeline 4.

[0037] Beneficial effects: Through the adjustment module 2, the two sealing caps 23 are moved to the height flush with the pressure pipeline 4. Through the clamping module 3, the two sealing caps 23 move closer to each other, so that the two sealing caps 23 clamp the pressure pipeline 4, forming a relatively airtight space between the pressure pipeline 4 and the two sealing caps. Turn on the external air pump, so that the external gas enters the valve 22 and the pressure pipeline 4 through the air pump. At the same time, observe the value of the pressure gauge 21. When the pressure gauge 21 reaches a certain value, turn off the external air pump, wait for a period of time, and observe the value of the pressure gauge 21 again. Compare the value at this time with the previous value to obtain the pressure resistance of the pressure pipeline 4.
