[0002] Due to its good anti-corrosion properties, graphite materials are widely used in some high-corrosion industries and fields. However, due to the low strength of graphite materials and the fact that they are brittle materials, various graphite parts are bonded or clamped together. Graphite tubes made of graphite materials are also fixed to graphite flanges by bonding.

[0003] After the production of graphite tubes is completed, it is necessary to randomly perform pressure testing on the graphite tube fittings produced in the same batch. The traditional pressure test of graphite tube fittings mainly releases the pressure on its cross section, but the lateral pressure resistance of graphite tube fittings is also an important parameter affecting the basic performance of graphite tube fittings. Traditional pressure testing equipment cannot simultaneously have the lateral and longitudinal stable clamping effect of graphite tube fittings. When the pressure testing equipment releases the pressure on the tube fittings to be tested, resulting in the splashing of residues from the broken tube fittings, the splashed residues can easily injure surrounding staff.

[0034] The material installation assembly includes a clamping platform 35, a second guide seat 36 and a clamping module. The clamping platform 35 is arranged on the base 1, the second guide seat 36 is arranged on the base 1 and is located on one side of the clamping platform 35, and the clamping module is arranged on the clamping platform 35 for clamping and fixing the pipe to be inspected.

[0035] In a specific case of the present embodiment, the clamping module includes a clamping drive disk 48, a plurality of connecting blocks 42, a clamping member and an exhaust structure. The clamping table 35 is provided with a plurality of adjustment grooves 41, each of which is movably provided with a connecting block 42. The connecting block 42 and the adjustment groove 41 are elastically connected, and each of the connecting blocks 42 is provided with a clamping member. The clamping drive disk 48 is movably provided on the base 1 and is located between the clamping table 35 and the second guide seat 36. The clamping drive disk 48 is provided with a plurality of through grooves 50, and the through grooves 50 are provided with an adjustment ramp, and the adjustment ramp is in abutment with the connecting block 42. The exhaust structure is provided on the second guide seat 36 and is connected to the suction cup 2. The exhaust structure is connected to the connecting block 42. When the connecting block 42 moves, it controls the exhaust structure to work synchronously and exhausts the air between the suction cup 2 and the ground.

[0036] In another specific case of this embodiment, the clamping member includes a longitudinal splint 43, a transverse splint, a pipe groove 46 and a pressure sensor 47. The longitudinal splint 43 is arranged on the connecting block 42, the transverse splint is movably arranged on the longitudinal splint 43 and the two are elastically connected, the pipe groove 46 is arranged on the transverse splint, the number of the pressure sensor 47 is at least one and is arranged on the longitudinal splint 43 and located on the moving path of the transverse splint, the pressure sensor 47 is electrically connected to the pressure release component, and the pressure sensor 47 adjusts the pressure release mode of the pressure release component when under pressure.

[0037] Of course, the present embodiment is not limited to the above-mentioned pressure sensor 47 to detect the position of the transverse clamping plate relative to the longitudinal clamping plate 43, and an infrared distance sensor or an ultrasonic distance sensor may be used instead, which are not listed here one by one.

[0038] It should be supplemented that the exhaust structure includes a second gear 49, a wave tube 37, an exhaust pipe 38, a piston rod 39 and a second clamping shaft 40. The number of the exhaust pipes 38 is the same as the number of the connecting blocks 42 and are arranged in a ring on the second guide seat 36. The exhaust pipe 38 and the second guide seat 36 are slidably matched. The piston rod 39 is movably set on the exhaust pipe 38 and the two are threadedly matched. The second clamping shaft 40 is movably inserted on the piston rod 39. The second gear 49 is movably set on the exhaust pipe 38 and is coaxially connected to the second clamping shaft 40.

[0039] In actual application, the pipe to be inspected is placed on the clamping table 35, and the pipe to be inspected is clamped longitudinally or transversely by controlling the clamping module. It should be specifically explained that when the pipe to be inspected is clamped longitudinally, the pipe to be inspected is placed on the clamping table 35, and the clamping drive disk 48 is rotated. Under the interference between the adjustment ramp and the second gear 49, the connecting block 42 can be driven to close along the adjustment groove 41 until the longitudinal clamping plate 43 clamps and fixes the surface of the pipe to be inspected. When the pipe to be inspected is clamped transversely, the pipe to be inspected is placed horizontally between the pipe grooves 46, and the position between the transverse clamping plates 45 is adjusted by rotating the clamping drive disk 48, so that the pipe grooves 46 clamp and fix the outer wall of the pipe to be inspected. When the transverse clamping plate 45 is displaced relative to the longitudinal clamping plate 43 and conflicts with the pressure sensor 47, the pressure sensor 47 can be adjusted according to the position of the pipe to be inspected. The pressure output mode of the pressure release component is adjusted by the installation mode, and when the clamping drive disk 48 rotates, the meshing action between the second gear 49 and the teeth 51 can drive the second gear 49 and the second clamping shaft 40 to rotate, thereby driving the piston rod 39 to rotate relative to the exhaust pipe 38, and under the action of the threaded cooperation between the piston rod 39 and the exhaust pipe 38, the piston rod 39 is driven to move relative to the exhaust pipe 38, so that the air between the suction cup 2 and the ground is extracted to reach a vacuum state, thereby increasing the stability of the entire device when performing pressure testing on the pipe to be tested. By controlling the operation of the pressure release component and adopting two different extrusion methods to extrude the pipe to be tested clamped horizontally or longitudinally until the pipe to be tested is instantly broken, the pressure release component can record the pressure bearing capacity data of the pipe to be tested; when the pressure release component is in contact with the pipe to be tested, the protection component can be controlled to work synchronously to perform protection treatment on the surrounding of the pipe to be tested.

[0042] After completing the clamping and fixing work of the pipe to be inspected, the driving motor 15 is controlled to be powered on and rotated, driving the first clamping shaft 17 and the pressure relief screw 18 to rotate, and under the action of the threaded cooperation between the pressure relief screw 18 and the pressure relief screw sleeve 19, the lifting seat 20 and the lifting platform 21 are driven to move in the vertical direction along the guide rail 14, thereby driving the extrusion structure to move toward the direction of the pipe to be inspected, and applying pressure to the pipe to be inspected through the extrusion structure.

The hydraulic pipe 24 is in a group and is symmetrically arranged on the lifting platform 21. The number of sliding columns is the same as the number of hydraulic pipes 24.

[0046] Non-restrictive, the present embodiment is not limited to the above-mentioned hydraulic cylinder 9 to adjust the position of the protective half box 4, and a linear motor or electric cylinder can also be used instead, which are not listed here one by one.

[0047] In actual application, when the pipe to be inspected is clamped longitudinally, the driving motor 15 is powered on to rotate and drives the extrusion plate 22 to move downward so that the extrusion plate 22 and the end face of the pipe to be inspected directly contact each other. When the pipe to be inspected is clamped and fixed transversely, the pressure sensor 47 can be pressurized, triggering the electromagnetic block 32 to be powered on and attracted, thereby driving the rack 30 to move. Under the meshing action between the gear and the rack 30, and the threaded cooperation between the adjusting screw 34 and the adjusting screw sleeve 33, the punch head 29 is driven to move downward, so that when the extrusion plate 22 moves downward, the punch head 29 and the outer surface of the pipe to be inspected are in contact with each other and the pressure resistance of the outer wall of the pipe to be inspected is tested. Regardless of whether the punch head 29 and the extrusion plate 22 are in contact with the pipe to be inspected, the sliding column can be driven to move relative to the hydraulic pipe 24, so that the liquid in the hydraulic pipe 24 is input into the buffer tank 25 The airbag is filled with hydraulic pressure and expanded (similar to a piston-type infusion cylinder). At this time, the pressure value applied by the punch head 29 or the extrusion plate 22 is obtained according to the contact position of the conductive block 27 and the resistor bar 28. When the pipe to be detected is broken due to excessive pressure, the data between the conductive block 27 and the resistor bar 28 is recorded. When a conflict occurs between the punch head 29 or the extrusion plate 22 and the pipe to be detected, part of the liquid in the hydraulic pipe 24 enters the hydraulic cylinder 9, thereby driving the hydraulic cylinder 9 to extend. Under the action of the first push arm 10, the moving block 11 is driven to move along the first guide seat 6, and under the action of the second push arm 12, the protective half-boxes 4 are controlled to move toward each other, and then the surrounding of the pipe to be detected is protected. By controlling the operation of the fan 5, the residue can be absorbed at the moment when the pipe to be detected is broken, so as to avoid the residue splashing and injuring the surrounding staff.
