The invention can be used for sealing detection of double oil pipes.

[0004] In the prior art including the above-mentioned patents, the air tightness and inner wall flatness of the high-pressure oil pipe need to be tested after production, and the existing testing method usually requires the high-pressure oil pipe to be tested step by step. When performing flatness testing and air tightness testing, the high-pressure oil pipe needs to be repositioned and installed on different testing equipment, which increases the operation steps and time and reduces the testing efficiency.

[0046] The first detection disk 15 is provided with first telescopic grooves matching the multiple telescopic touch panels 21, and the multiple telescopic touch panels 21 are in a relatively sealed state with the inner wall of the first detection disk 15. The second detection disk 16 is provided with second telescopic grooves matching the multiple telescopic touch panels 21, and the multiple telescopic touch panels 21 are in a relatively sealed state with the inner wall of the second detection disk 16. The multiple inner fixed plates 24 are all provided with inner sliding grooves matching the L-shaped clamping blocks 25.

[0047] A plurality of spiral transmission plates 32 are distributed on the outer fixing tube 31 in a ring array, and a plurality of transmission rods 341 are distributed on the inner wall of the transmission cylinder 34 in a ring array.

[0048] The clamping assembly 11 includes a clamping platform 111 fixed on the inner wall of the tooling assembly 1, and two clamping seats 113 are slidably mounted on the clamping platform 111. Two electric telescopic rods 112 are mounted on the top of the clamping platform 111, and the output ends of the two electric telescopic rods 112 are respectively fixedly connected to the two clamping seats 113, and the top of each clamping seat 113 is in contact with the arc-shaped outer wall of the high-pressure oil pipe body 12.

[0049] When testing the high-pressure oil pipe body 12, the two ends of the high-pressure oil pipe body 12 can be placed between the two clamping seats 113, and then the two electric telescopic rods 112 are started at the same time, and the two clamping seats 113 are driven to slide on the top of the clamping platform 111, so that the high-pressure oil pipe body 12 can be straightened and the end of the high-pressure oil pipe body 12 close to the sponge marking block 37 is in the same plane as the contact surface of the sponge marking block 37. Since the above belongs to the prior art, it will not be elaborated here.

[0050] At this time, the hydraulic rod 14 can be started to drive the propulsion frame 141 fixedly connected to its output end to move toward the high-pressure oil pipe body 12, and the first detection disk 15 and the second detection disk 16 fixedly connected to the sealing ring 42 can be driven to move at the same time under the connection of the sealing ring 42. When any one of the two groups of telescopic touch plates 21 on the first detection disk 15 and the second detection disk 16 contacts the protrusion on the inner wall of the high-pressure oil pipe body 12, when the telescopic touch plate 21 on the first detection disk 15 contacts the protrusion, the telescopic touch plate 21 can be pushed to slide into the first detection disk 15, and the telescopic spring 22 can be compressed at the same time. At this time, the displacement sensor 23 can record the position of the protrusion. And the displacement sensor 23 detects the moving distance, and sends the data to the data processing terminal 13 through the data processing module. At the same time, the sliding of the telescopic touch plate 21 can drive the inner fixed plate 24 fixedly connected thereto to slide, so that the L-shaped clamping block 25 is in close contact with the clamping block 261. Since the position of the clamping block 261 is in a relatively static state, the L-shaped clamping block 25 can be pushed to slide inside the inner slide groove, and the reset spring 251 can be compressed. When the top end of the L-shaped clamping block 25 slides to the bottom of the clamping block 261, the elastic force of the reset spring 251 can make the L-shaped clamping block 25 slide toward the clamping block 261 until it slides to the bottom of the clamping block 261. At this time, Under the limiting action of the clamping block 261, the telescopic spring 22 is in a compressed state. With the continuous advancement of the hydraulic rod 14, when the multiple spiral transmission plates 32 on the external fixed tube 31 contact the multiple transmission rods 341 fixed on the inner wall of the transmission cylinder 34, the connecting tube inside the transmission cylinder 34 can be connected with the external fixed tube 31. At this time, the transmission rod 341 is in a relatively static state, and the transmission rod 341 can be pushed along the outer wall of the spiral transmission plate 32. In this process, the external fixed tube 31 can drive the two transmission tubes 26 to rotate around the connection position of the first detection disk 15 and the second detection disk 16 respectively, and at the same time compress the transmission tubes 26 and the first detection disk 15 respectively. , and the second detection disk 16. When the rotation of the transmission tube 26 drives the clamping block 261 to move to the separation position of the L-shaped clamping block 25, the L-shaped clamping block 25 can move toward the outside of the first detection disk 15 under the elastic force of the telescopic spring 22, and the telescopic touch plate 21 can slide at the same time. Since the internal space of the first detection disk 15 connected with the connecting tube through the external fixed tube 31 is in a sealed state, the sliding of the telescopic touch plate 21 can apply negative pressure to the internal space, so that the piston rod 36 sliding inside the piston cylinder 35 can slide upward, and drive the sponge marking block 37 to move upward, so as to mark the high-pressure oil pipe body 12, which is convenient for the operator to identify.

[0051] The sealing assembly 4 also includes a fixed disk 41 fixed to the outer wall of the propulsion frame 141, the interior of the fixed disk 41 is hollow, and the fixed disk 41 is located at the center of the two sealing rings 42, a connecting tube 43 is fixedly provided on the transmission tube 26 inside the second detection disk 16, and a port disk 44 is fixedly provided on the connecting tube 43 near one end of the fixed disk 41, and a blocking disk is fixedly provided between the other end of the connecting tube 43 and the transmission tube 26, and the port disk 44 rotates on the inner wall of the fixed disk 41, and a plurality of connecting rods 45 are slidably provided on the port disk 44, and both ends of each connecting rod 45 are penetrated by the interior of the fixed disk 41 To both sides of the outer wall of the fixed disk 41, both ends of each connecting rod 45 extend to the inside of the two sealing rings 42 respectively, a plurality of arc-shaped slide grooves 441 matching the plurality of connecting rods 45 are opened on the port disk 44, and a plurality of straight slide grooves 411 matching the plurality of connecting rods 45 are opened on the fixed disk 41, two sealing push rods 46 are fixed at both ends of each connecting rod 45, and each sealing push rod 46 slides on the inner wall of the sealing push rod 46, a sealing ring 47 is fixedly arranged on the arc-shaped outer wall of each sealing push rod 46, and each group of sealing push rods 46 is fixedly connected to the inner wall of the sealing ring 47.

[0052] A plurality of straight slide grooves 411 are distributed in an annular array on the fixed disk 41 , a plurality of arcuate slide grooves 441 are distributed in an annular array on the port disk 44 , and each sealing push rod 46 is provided with a plurality of movable through grooves matching the plurality of connecting rods 45 .

[0053] An air inlet hole is formed on the sealing push rod 46 close to one side of the hydraulic rod 14, and an air inlet pipe is fixedly disposed inside the air inlet hole.

[0054] When the high-pressure oil pipe body 12 is tested, the two electric telescopic rods 112 are started and the clamping assembly 11 is cooperated to make the high-pressure oil pipe body 12 in a straightened state, and then the hydraulic rod 14 is started. At the same time, with the cooperation of the smoothness detection assembly 2, the transmission tube 26 can be pushed toward the transmission cylinder 34 while the transmission tube 26 rotates. At this time, the connecting cylinder 43 fixedly connected to the transmission tube 26 can be driven to rotate, and then the port plate 44 can be driven to rotate. Since the multiple connecting rods 45 are slidably connected to the multiple arc-shaped slide grooves 441 provided on the port plate 44, and the multiple connecting rods 45 slide simultaneously Inside the multiple straight grooves 411 opened on the fixed disk 41, and at this time the fixed disk 41 is in a relatively static state, the multiple connecting rods 45 can slide toward the arc-shaped outer wall of the fixed disk 41 at the same time, and then drive the multiple sealing push rods 46 slidingly connected to the two sealing rings 42 respectively to push the sealing ring 47, so that the sealing ring 47 is deformed, and the sealing ring 47 is tightly attached to the inner wall of the high-pressure oil pipe body 12 and clamped and sealed, thereby playing a sealing role. Then, by connecting the output end of the air tightness detector with the intake pipe, the air tightness test of the high-pressure oil pipe body 12 can be directly performed.

[0055] The working principle and use process of the present invention are as follows: when the high-pressure oil pipe body 12 is inspected, by starting the two electric telescopic rods 112 and cooperating with the clamping assembly 11, the high-pressure oil pipe body 12 can be in a straightened state, and then the hydraulic rod 14 can be started. At the same time, with the cooperation of the smoothness detection assembly 2 and the marking assembly 3, it is assumed here that in this process, the telescopic touch plate 21 on the first detection disk 15 contacts the convex block, which can make the transmission tube 26 rotate, and then make the sponge marking block 37 move upward under the action of negative pressure, so that the high-pressure oil pipe body 12 can be marked, and at the same time, the corresponding telescopic touch plate 21 on the first detection disk 15 contacts the convex block. The displacement sensor 23 on the plate 21 can record the position of the bump, and the displacement sensor 23 detects the moving distance, and sends the data to the data processing terminal 13 through the data processing module. The rotation of the transmission tube 26 can simultaneously, with the cooperation of the sealing assembly 4, cause multiple sealing push rods 46 to push the sealing ring 47, causing the sealing ring 47 to deform, and make the sealing ring 47 tightly attached to the inner wall of the high-pressure oil pipe body 12 and clamp and seal. Then, the output end of the airtightness detector can be connected to the intake pipe to detect the airtightness of the high-pressure oil pipe body 12.
