[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example: Figure 1-Figure 12 As shown, the present invention provides a technical solution for a petroleum pipeline sealing detection device based on laser technology, including a motion structure 1, the motion structure 1 includes a mounting frame 11, a support structure 2 is installed on one side of the mounting frame 11, a plurality of laser scanners 4 are installed on the support structure 2, three biaxial pneumatic telescopic cylinders 115 are fixedly inserted on the mounting frame 11, multi-directional support components are installed on both piston ends of the three biaxial pneumatic telescopic cylinders 115, mounting frames 13 are arranged at both ends of the three biaxial pneumatic telescopic cylinders 115, and limiting structures 3 are installed inside the three mounting frames 13 close to the support structure 2, and the limiting structures 3 apply a corresponding state of force to the support structure 2 according to the working state of the motion structure 1.

[0034] Specifically, three batteries 12 are fixedly inserted on the mounting frame 11, and the batteries 12 store electricity to provide power for the operation of structures such as the dual-axis pneumatic telescopic cylinder 115, the forward and reverse motor 24, the laser scanner 4, the brake 17, and the forward and reverse motor 112. Installing an invisible communication module on the motion structure 1 for data transmission and control command reception is an existing well-known technology and will not be elaborated here.

[0035] Three biaxial pneumatic telescopic cylinders 115 are fixedly inserted on the annular mounting frame 11, and multi-directional support components are installed on both piston ends of the three biaxial pneumatic telescopic cylinders 115. A hollow mounting frame 2 13 is set at both ends of the three biaxial pneumatic telescopic cylinders 115, and one end of the mounting frame 2 13 is fixedly connected to the mounting frame 11.

[0036] The multi-directional support assembly is composed of a mounting frame 3 14 fixedly connected to one end of the mounting frame 2 13 away from the mounting frame 1 11, a support shaft 15 rotatably inserted inside the mounting frame 3 14 close to the side of the mounting frame 11, and a mounting frame 4 19 fixedly installed on the outside of the support shaft 15 as the main structure, and the mounting frame 4 19 fixedly installed on the outside of the support shaft 15 can rotate inside the mounting frame 3 14, and a support shaft 2 110 is rotatably inserted in the mounting frame 4 19 at a position away from the mounting frame 11, and a wheel 111 is fixedly sleeved on the outside of the support shaft 2 110, and the mounting frame 4 19, the support shaft 2 110 and the wheel 111 constitute a support wheel, and the support shaft 15 fixed to the mounting frame 4 19 can rotate. The support wheel can be rotated around the support shaft 15 as the axis, and the rotation angle of the support wheel can be controlled to control the support wheel to contact with oil pipelines of different diameters.

[0037] The bottoms of the two transmission gears 18 fixedly sleeved on the outside of the support shaft 15 are meshed with racks 113, and a fixed plate 116 is fixedly connected between the two racks 113. Under the action of the fixed plate 116, the two racks 113 move synchronously, and the transmission gears 18 meshed with the two racks 113 also rotate synchronously in the corresponding direction. The fixed plate 116 is fixedly connected to the piston end of the adjacent double-axis pneumatic telescopic cylinder 115, and the fixed plate 116 is set inside the adjacent mounting frame 2 13 and is slidably connected to the mounting frame 2 13. The operation of the double-axis pneumatic telescopic cylinder 115 can control the movement of the fixed plate 116 and the rack 113 fixedly connected to the fixed plate 116.

[0038] A support frame five 119 is fixedly connected between two adjacent mounting frames three 14, and a mounting frame three 14 is fixedly connected between the six mounting frames three 14 and the mounting frame one 11, so the mounting frame one 11, the mounting frame three 14 and the support frame five 119 are integrated and can only move synchronously.

[0039] The specific usage of the oil pipeline laser detection device composed of the motion structure 1, the support structure 2, and the limit structure 3 in this application is as follows:

[0040] Embodiment 1:

[0041] When the inner diameter of the oil pipeline is larger than the outer diameter of the mounting frame 11, the user holds the oil pipeline laser detection device and pushes it into the oil pipeline. When the user holds the mounting frame 11 or one of the supporting frames 5 119, the supporting frame 5 119 and the mounting frame 3 14 fixedly connected to the supporting frame 5 119 and the mounting frame 11 fixedly connected to the mounting frame 2 13 cannot move.

[0042] Then, the three double-axis pneumatic telescopic cylinders 115 are controlled to work and extend. At this time, the fixed plate 116 fixed at the two piston ends of the double-axis pneumatic telescopic cylinder 115 moves toward the mounting frame 3 14, and the rack 113 fixedly connected to the fixed plate 116 moves. Under the action of the transmission gear 18 meshing with the rack 113, the support shaft 15 fixedly connected to the transmission gear 18 rotates inside the mounting frame 3 14, and the support shaft 15, the mounting frame 4 19 and the support shaft 2 110 all rotate outward, and the six multi-directional support components are expanded outward. Finally, the six wheels 111 contact the inner wall of the oil pipeline, and the double-axis pneumatic telescopic cylinder 115 is controlled to stop working. During this process, the user adjusts his own state according to the force transmitted by the expansion of the multi-directional support component, so that the multi-directional support component can be smoothly expanded to support the oil pipeline laser detection equipment to the inside of the oil pipeline.

[0043] The two sides of the mounting frame 4 19 are respectively fixedly connected with a forward and reverse motor 112 and a balance block 120. The arrangement of the forward and reverse motor 112 and the balance block 120 makes the weight on both sides of the mounting frame 4 19 in a balanced state, and one end of the support shaft 2 110 is fixedly connected to the output end of the forward and reverse motor 112, and the other end of the support shaft 2 110 is rotationally connected to the balance block 120. At this time, the forward and reverse motor 112 is controlled to rotate forward or reverse, so that the support shaft 2 110 and the wheel 111 fixedly connected to the outer side of the support shaft 2 110 can rotate, and the six forward and reverse motors 112 can be controlled to rotate forward or reverse synchronously, so as to control the rotation direction of the six wheels 111, and control the direction of movement of the oil pipeline laser detection equipment inside the oil pipeline;

[0044] A support structure 2 is installed on one side of the mounting frame 11. The detection paths of multiple laser scanners 4 supported by the support structure 2 form a circular path. As the oil pipeline laser detection equipment moves inside the oil pipeline, multiple laser scanners 4 detect and collect data on cracks, holes, and wear depressions on the inner wall of the oil pipeline, and a comprehensive judgment is made on the sealing performance of the oil pipeline at a later stage.

[0045] Embodiment 2:

[0046] When the outer diameter of the oil pipeline is smaller than the inner diameter of the mounting frame 11, since the mounting frame 11 is set in a circular ring shape, the user holds the mounting frame 11 or one of the supporting frames 5 119 and then holds the oil pipeline laser detection device and sets it on the outside of the oil pipeline.

[0047] Then, the three double-axis pneumatic telescopic cylinders 115 are controlled to work and retract, and the double-axis pneumatic telescopic cylinders 115 drive the fixed plate 116 away from the mounting frame 3 14. Under the action of the fixed plate 116 and the transmission gear 18 meshed with the rack 113 fixedly connected to the fixed plate 116, the support shaft 15 rotates, and the mounting frame 4 19 fixedly connected to the support shaft 15 rotates inward, and the six multi-directional support components are expanded inward. Finally, the multiple support shafts 2 110 move to contact the outer wall of the oil pipeline, and the six inwardly expanded multi-directional support components support the mounting frame 11 on the outer wall of the oil pipeline.

[0048] The forward and reverse motor 24 in the control support structure 2 works synchronously with the double-axis pneumatic telescopic cylinder 115. The forward and reverse motor 24 is arranged inside the mounting groove 25 formed on the mounting frame 11 and is fixedly connected to the mounting frame 11, so the forward and reverse motor 24 drives the support shaft 3 23 fixedly connected at the output end to rotate. The outer sides of multiple support shafts 3 23 in the support structure 2 are fixedly sleeved with a transmission gear 22, and multiple transmission gears 22 are all meshed with the ring gear 21 rotatably connected to the mounting frame 11, and one end of the remaining support shafts 3 23 is rotatably connected to the mounting frame 11, so the rotating support shaft 3 23 drives the outer transmission gear 2 22 to rotate, the transmission gear 2 22 drives the meshing ring gear 21 to rotate, and the ring gear 21 drives the remaining transmission gears 22 to rotate; finally, the multiple support shafts 3 23 and the support frame 6 26 fixedly connected at one end of the support shaft 3 23 rotate, and the laser scanner 4 is installed inside the support frame 6 26 so they rotate synchronously.

[0049] After the forward and reverse motor 24 stops working, the multiple laser scanners 4 rotate 180 degrees, and the multiple laser scanners 4 face the outer wall of the oil pipeline.

[0050] Then, the forward and reverse motor 112 is controlled to work, so that the oil pipeline laser detection equipment can move outside the oil pipeline, perform laser detection on the outer wall of the oil pipeline, and collect the oil pipeline sealing data.

[0051] Embodiment three:

[0052] When the biaxial pneumatic telescopic cylinder 115 is in the initial state, the mounting frame 4 19 is stored inside the mounting frame 3 14, and the multi-directional support assembly is in a folded state. At this time, the oil pipeline laser detection equipment is in a relatively regular state as a whole, and the oil pipeline laser detection equipment is more convenient to store;

[0053] At this time, the fixing plate 318 in the limiting structure 3 that is slidably connected to the inside of the mounting frame 2 13 is on the side of the mounting frame 2 13 away from the mounting frame 1 11. At this time, the hydraulic pressure inside the rubber liquid storage part 2 317 that is fixedly connected between the fixing plate 318 and the transfer box 38 is low, and the multiple spring-type telescopic rods 316 that are fixedly connected between the transfer box 38 and the mounting frame 1 11 are in an extended state. Under the action of the multiple spring-type telescopic rods 316, the transfer box 38 is always subjected to a force that moves toward the mounting frame 3 14;

[0054] A support shaft 4 32 is provided on one side of the transfer box 38 close to the mounting frame 11, and the support shaft 4 32 is rotatably connected between the mounting frame 2 13 and the mounting frame 11, and a mounting groove 4 37 is provided on the outer side of the transmission gear 3 33 fixedly sleeved on the outer side of the support shaft 4 32, and a fixing plate 2 36 is fixedly connected between the friction plate 2 35 provided inside the mounting groove 4 37 and the transfer box 38, and the transfer box 38 applies force to the friction plate 2 35 through the fixing plate 2 36, and friction plates 1 34 are provided on both sides of the friction plate 2 35 to increase the friction force. At this time, the friction plate 2 35 contacts the friction plate 1 34 close to the mounting frame 3 14 of the two friction plates 1 34 fixedly connected to the transmission gear 3 33, and the friction plate 2 35 subjected to the motion force contacts the friction plate 1 34 in real time, and there is a certain friction between the friction plate 2 35 and the friction plate 1 34, and the transmission gear 3 33 fixedly connected with the friction plate 1 34 is limited;

[0055] Because the bottom of the mounting frame 2 13 is provided with a mounting groove 31 , the support shaft 4 32 is arranged inside the mounting groove 31 , and the transmission gear 3 33 is meshed with the ring gear 21 through the mounting groove 31 , and the ring gear 21 is limited by the transmission gear 3 33 at this time.

[0056] When the dual-axis pneumatic telescopic cylinder 115 is in the initial state and the mounting frame 4 19 is stored inside the mounting frame 3 14, the limiting structures 3 arranged in the three mounting frames 2 13 close to the support structure 2 are in a non-working state. At this time, the transmission gears 3 33 of the three limiting structures 3 are all in a limited state, and the limiting forces received by the three transmission gears 3 33 are applied to the meshing ring gear 21 to prevent the ring gear 21 from rotating. At this time, the limiting structure 3 has the effect of sharing the force applied by the laser scanner 4 to the ring gear 21, reducing the burden on the forward and reverse motors 24, and ensuring the accuracy of the angle adjustment of the laser scanner 4 by preventing the ring gear 21 from rotating.

[0057] When the biaxial pneumatic telescopic cylinder 115 is extended, the fixed plate 116 moves toward the mounting frame 3 14. At this time, the fixed plate 3 318 has not been subjected to the force applied by the fixed plate 116, and the working state of the multiple spring-type telescopic rods 316 remains unchanged.

[0058] Embodiment 4: During the implementation of the technical solution provided in Embodiment 2, the fixed plate 116 moves toward the mounting frame 11, and the fixed plate 116 will push the fixed plate 318 to move. The fixed plate 318 squeezes the rubber liquid storage part 2 317. The force applied by the rubber liquid storage part 2 317 to the transfer box 38 is greater than the force applied by the multiple spring-type telescopic rods 316 to the transfer box 38, so the transfer box 38 moves to a position away from the laser scanner 4. After the transfer box 38 moves a certain distance, the friction plate 2 35 contacts the friction plate 1 34 close to the mounting frame 11; during the movement of the transfer box 38, the limit of the transmission gear 3 33 is removed, providing time for the support structure 2 to drive the laser scanner 4 to rotate 180°. After the laser scanner 4 rotates 190°, the forward and reverse motor 24 stops working, and then the transfer box 38 moves to contact the friction plate 1 34 close to the mounting frame 11.

[0059] As the fixed plate 116 continues to move, the rubber liquid storage member 317 applies a certain force to the transfer box 38, and the hydraulic pressure inside the rubber liquid storage member 317 and the transfer box 38 increases to a certain value;

[0060] After the hydraulic pressure inside the rubber liquid storage part 2 317 and the transfer box 38 increases to a certain value, since the pressure relief valve 39 and the solenoid valve 311 are fixedly connected to both sides of the transfer box 38, and the solenoid valve 311 is in a normally closed state, the pressure relief valve 39 fixed on one side of the transfer box 38 is opened by the high-pressure liquid. Since the volume of the internal channel of the pressure relief valve 39 is limited, the transfer box 38 still keeps exerting force on the friction plate 2 35 to make the friction plate 2 35 rub against the friction plate 1 34.

[0061] Guide frames 312 are provided on both sides of the top of the transfer box 38, and a diversion box 313 is fixedly connected inside the guide frame 312 to which the outer shell of the double-axis pneumatic telescopic cylinder 115 is fixedly connected, and one end of the pressure relief valve 39 and the solenoid valve 311 are fixedly connected to a guide tube 310, and one end of the two guide tubes 310 are respectively fixedly connected to the two diversion boxes 313, and the liquid medium inside the rubber liquid storage part 317 enters the diversion box 313 through the guide tube 310. After the internal hydraulic pressure of the rubber liquid storage part 314 fixedly connected to one end of the diversion box 313 reaches a certain value, the rubber liquid storage part 314 can expand and extend to meet the needs of multi-distance movement of the fixed plate 116.

[0062] Embodiment 5: After embodiment 2 is completed in real time, the dual-axis pneumatic telescopic cylinder 115 is controlled to push the fixed plate 116 to restore to the initial state, the solenoid valve 311 is controlled to open, and a guide tube 2 315 is fixedly connected between the two diversion boxes 313. The liquid medium inside the rubber liquid storage component 1 314 and the diversion box 313 can flow back to the rubber liquid storage component 2 317 through the solenoid valve 311. During the process, the support structure 2 is controlled to restore the laser scanner 4 to its original state.

[0063] In summary, during use, the oil pipeline laser detection equipment provided by the present application only needs to control the working state of the dual-axis pneumatic telescopic cylinder 115 to control the six multi-directional support components to expand outward or inward, so that the oil pipeline laser detection equipment can move inside or outside the oil pipeline, and only needs to control the expansion degree of the multi-directional support components to enable the multi-directional support components to support the oil pipeline laser detection equipment on oil pipelines of different diameters, which can meet the needs of sealing detection of oil pipelines of various diameters.

[0064] In addition, such as Figure 2 As shown, a thread groove 118 is provided on the outside of the mounting frame 11. When the oil pipeline laser detection equipment is supported on the outside of the oil pipeline by six multi-directional support components, a handle can be installed on the outside of the mounting frame 11 through the thread groove 118 and the thread structure, and the staff can manually control the movement of the oil pipeline laser detection equipment.

[0065] In addition, such as Figure 4 As shown, a weight-reducing groove 117 is provided on the mounting frame 4 19. The setting of the weight-reducing groove 117 reduces the weight of the mounting frame 4 19, and the mounting frame 11 is set in a circular ring shape, providing a lighter oil pipeline laser detection device.

[0066] In addition, such as Figure 4 and Figure 7 As shown, mounting grooves 16 are provided at both ends of the outer side of the support shaft 15, and brakes 17 are fixedly installed on both sides of the inside of the mounting frame 3 14. The brake 17 is sleeved on the outer side of the support shaft 15 through the mounting grooves 16. After the mounting frame 4 19 is unfolded, the brake 17 can be controlled to limit and fix the position of the support shaft 15, so that the mounting frame 4 19 is maintained at a required angle, thereby ensuring the stability of the oil pipeline laser detection equipment.

[0067] In addition, such as Fig.10 As shown, the guide frame 312 passes through the fixed plate 116 , and the guide frame 312 limits and guides the movement of the fixed plate 116 .
