Description

Technical Field

[0001] This invention relates to the field of steel pipe inner wall grinding technology, specifically a steel pipe inner wall treatment device. Background Technology

[0002] Steel pipes are hollow, long strips of material made of steel, with their core characteristic being their hollow structure. They are mainly divided into seamless steel pipes, which are produced through piercing and rolling, and welded steel pipes, which are produced through coiling and welding. Steel pipes combine the high strength and toughness of steel with the lightweight, excellent mechanical properties, and fluid transport capacity of a hollow structure, making them a widely used basic industrial material. They are extensively used in fluid transport, building structural support, machinery manufacturing, manufacturing equipment, the energy industry, and many daily necessities and furniture products.

[0003] In existing technology, after the steel pipe to be ground is transported to the designated position, the hydraulic cylinder actuates, driving the tracking wheel to move and lightly touch the outer wall of the steel pipe. The hydraulic cylinder stops when it reaches the preset stroke. Under the action of the return spring, the grinding wheel inside the steel pipe moves towards the inner wall of the steel pipe and contacts it. At this time, the distance between the tracking wheel and the grinding wheel is the steel pipe wall thickness. The stroke of the hydraulic cylinder can be adjusted to accommodate steel pipes with different wall thicknesses. The self-rotating motor starts and drives the grinding wheel to rotate. During the rotation of the grinding wheel, the inner wall of the steel pipe end is ground and corrected. The revolution mechanism starts and drives the tracking mechanism and the grinding wheel to revolve together, rotating around the center line of the steel pipe. During the revolution, the grinding wheel maintains its rotation to grind the inner wall of the steel pipe end it passes through. Because the distance between the tracking wheel and the grinding wheel remains unchanged, the wall thickness of the steel pipe end is uniform. However, in existing technology, it is not convenient to perform wide-coverage grinding of the inner wall of the pipe, and the cooling efficiency is low. Therefore, there is considerable room for improvement in existing technology. Summary of the Invention

The rotating shell mechanism 6 is provided with a plurality of pressing mechanisms 7. The pressing mechanism 7 is provided with a grinding belt mechanism 8. The grinding belt mechanism 8 is provided with an elastic vibration clamping plate mechanism 9. The deflection connection mechanism 3 is used to connect the first installation pipe mechanism 1 and the second installation pipe mechanism 2. The first installation pipe mechanism 1 and the second installation pipe mechanism 2 are used to realize the circulation of coolant. The movable chuck mechanism 4 is used to realize the movement of the device along the inner wall of the steel pipe. The pneumatic sealing mechanism 5 is used to partially seal the inner wall of the steel pipe.

The elastic vibration clamping plate mechanism 9 is used to drive the grinding belt mechanism 8 to vibrate.

[0030] The movable chuck mechanism 4 includes a fixed ring 401 fixed to the first tube 101. A plurality of first displacement seats 402 are fixedly connected to the outer surface of the fixed ring 401. The first displacement seats 402 are rotatably connected to the deflection lever 403. A movable motor 404 is provided on the deflection lever 403. The output shaft of the movable motor 404 is fixedly connected to the movable wheel 405. The movable wheel 405 and the deflection lever 403 are rotatably connected. A first elastic element 406 is fixedly connected to the side of the fixed ring 401. A movable ring 407 is fixedly connected to the end of the first elastic element 406 away from the fixed ring 401. The movable ring 407 is slidably connected to the first tube 101. A plurality of second displacement seats 408 are fixedly connected to the movable ring 407. The second displacement seats 408 are rotatably connected to the support rod 409. The end of the support rod 409 away from the second displacement seats 408 is rotatably connected to the third displacement seat 410. The third displacement seat 410 and the deflection lever 403 are fixedly connected.

[0031] Specifically, under the action of the first elastic element 406, the moving ring 407 can move towards the fixed ring 401, thereby causing the support rod 409 to deflect, which in turn drives the deflection lever 403 to deflect around the first displacement seat 402, causing the moving wheel 405 to abut against the inner wall of the steel pipe. At this time, the moving motor 404 is turned on, and the output shaft of the moving motor 404 rotates, which drives the moving wheel 405 to rotate, thereby driving the equipment to move along the inner wall of the steel pipe.

[0032] The first installation pipe mechanism 1 includes a first pipe body 101, which is open at one end and closed at the other. The first pipe body 101 has several first inlet / outlet ports 102, and a first switching valve is installed inside the first pipe body 101. The second installation pipe mechanism 2 includes a second pipe body 201, which is open at one end and closed at the other. The second pipe body 201 has several second inlet / outlet ports 202, and a second switching valve is installed inside the second pipe body 201. The pneumatic sealing mechanism 5 includes a threaded mounting ring 501 that is threadedly connected to the first tube body 101. The threaded mounting ring 501 is fixedly connected to a fixed ring shell 502. The fixed ring shell 502 is provided with a vent pipe 503 and a control valve. The fixed ring shell 502 is provided with an annular mounting groove 504 and an annular through groove 505. An inflation / deflation machine 506 is provided inside the fixed ring shell 502. The inflation / deflation machine 506 is connected to a rubber inflation ring 507. A plurality of second elastic elements 508 are provided between the rubber inflation ring 507 and the fixed ring shell 502.

[0033] In an embodiment of the present invention, the inflation / deflation machine 506 includes an electrically controlled deflation valve located at the air outlet of the rubber inflation ring 507 and an electrically controlled inflation pump located at the air inlet of the rubber inflation ring 507. When deflation is required, the electrically controlled deflation valve is opened to discharge the gas inside the rubber inflation ring 507. When inflation is required, the electrically controlled inflation pump is opened to inflate the rubber inflation ring 507.

[0034] Specifically, turning on the inflation / deflation machine 506 and injecting gas into the rubber inflation ring 507 will cause the rubber inflation ring 507 to expand and come into contact with the inner wall of the steel pipe. Since the rubber inflation ring 507 is elastic, it can adapt to the sealing of steel pipes with a certain diameter. At this time, cooling gas can be introduced between the two pneumatic sealing mechanisms 5 through the vent pipe 503.

[0035] Additionally, coolant can be poured into the first pipe 101 and discharged into the enclosed space through the first inlet and outlet 102 to cool the grinding position and remove impurities generated during grinding. The cooled coolant is discharged from the second pipe 201 through the second inlet and outlet 202.

[0036] The rotating shell mechanism 6 includes a first sealing groove 601 and a second sealing groove 602 fixed on the first tube 101. A first sealing ring 603 is provided in the first sealing groove 601, and a second sealing ring 604 is provided in the second sealing groove 602. A rotating mounting shell 605 is provided in the first sealing groove 601 and the second sealing groove 602. A rotary motor 606 is provided on the first tube 101. The output shaft of the rotary motor 606 is fixedly connected to a gear shaft 607. The gear shaft 607 is fixedly connected to a first gear 608. A second gear 609 is fixedly connected to the inner wall of the rotating mounting shell 605. The first gear 608 and the second gear 609 mesh.

[0037] Specifically, turning on the rotary motor 606 can drive the gear shaft 607 to rotate. The rotation of the gear shaft 607 will drive the first gear 608 to rotate, which in turn will drive the second gear 609 to rotate. The rotation of the second gear 609 will then drive the rotating mounting housing 605 to rotate.

[0038] The clamping mechanism 7 includes a clamping sleeve 701 fixed on a rotating mounting shell 605. A linear motor 702 is fixedly connected inside the clamping sleeve 701. An adjusting block 703 is fixedly connected to the end of the linear motor 702. A third elastic element 704 is fixedly connected to the adjusting block 703. A clamping block 705 is fixedly connected to the end of the third elastic element 704 away from the adjusting block 703. A fourth elastic element 706 is fixedly connected between the clamping block 705 and the clamping sleeve 701. A clamping rod 707 is fixedly connected to the clamping block 705. The clamping rod 707 passes through the clamping sleeve 701 and is slidably connected to the clamping sleeve 701. The grinding belt mechanism 8 is fixed to the mounting plate 801 on the clamping rod 707. The mounting plate 801 has several symmetrically arranged movable frame slots 802. Movable frames 803 are arranged in the movable frame slots 802. The movable frames 803 and the mounting plate 801 are slidably connected. A fifth elastic element 804 is fixedly connected between the movable frames 803 and the mounting plate 801. The movable frames 803 are rotatably connected to the contact wheel 805. The mounting plate 801 is fixedly connected to two side plates 806. The two side plates 806 are symmetrically arranged on the mounting plate 801. The side plates 806 have displacement slots 807. The side plates 806 are fixedly connected to a sixth elastic element 808. The sixth elastic element 808 is fixedly connected to a displacement block 809. The displacement block 809 and the side plates 806 are slidably connected. A drive wheel 810 is arranged between the two displacement blocks 809. A hub motor is arranged in the drive wheel 810. The hub motor is used to drive the drive wheel to rotate. Grinding belts 811 are arranged on the drive wheel 810 and the contact wheel 805. The elastic vibration plate mechanism 9 includes an elastic spring plate 901 fixed on two movable frames 803. The elastic spring plate 901 is in contact with the grinding belt 811, and a vibration motor 902 is provided on the elastic spring plate 901.

[0039] Specifically, activating the linear motor 702 causes the adjusting block 703 to shift, thereby controlling the position of the third elastic element 704, which in turn adjusts the position of the clamping block 705, thereby adjusting the clamping state of the fourth elastic element 706, which in turn adjusts the position of the clamping rod 707, thereby adjusting the contact pressure between the grinding belt 811 and the inner wall of the steel pipe. At the same time, due to the presence of the elastic spring plate 901, the grinding belt 811 can amplify the area of ​​contact with the inner wall of the steel pipe. At this time, activating the hub motor inside the drive wheel 810 causes the drive wheel 810 to rotate. The rotation of the drive wheel 810 drives the grinding belt 811 to rotate, and the rotation of the grinding belt 811 can grind the inner wall of the steel pipe.

[0040] In addition, turning on the vibration motor 902 can drive the elastic spring plate 901 to vibrate, which in turn drives the grinding belt 811 to vibrate, thereby enhancing the grinding efficiency.

[0041] Example 2, see below. Figures 1-2 The deflection connection mechanism 3 includes a first connecting rod 301 fixed to the first tube 101, the first connecting rod 301 fixedly connected to a ball bushing 302, a first reset magnet provided in the middle of the inner wall of the ball bushing 302, a ball shaft 303 provided inside the ball bushing 302, a second reset magnet provided in the middle of the outer side of the ball shaft 303, the first reset magnet and the second reset magnet are opposite magnets, the ball shaft 303 is fixedly connected to a second connecting rod 304, and the second connecting rod 304 is fixedly connected to the second tube 201.

[0042] Specifically, by setting the ball bushing 302 and the ball shaft 303, the relative deflection displacement of the first tube 101 and the second tube 201 can be realized. Since the first reset magnet and the second reset magnet are opposite magnets, the return of the ball bushing 302 and the ball shaft 303 can be guaranteed.

[0043] In the implementation of this invention, the required equipment is first placed inside a steel pipe. At this time, under the action of the moving chuck mechanism 4, it can make contact with the inner wall of the steel pipe. If a closed grinding process is required, two pneumatic sealing mechanisms 5 are opened. If no coolant is needed for cooling, low-temperature gas is directly introduced into the two pneumatic sealing mechanisms 5 through the pneumatic sealing mechanisms 5 to avoid high temperature during grinding of the inner wall of the steel pipe. If coolant is needed for cooling, coolant is introduced between the two pneumatic sealing mechanisms 5 through the first installation pipe 1 to cool the grinding position. At the same time, the debris generated during grinding can be carried out through the second installation pipe mechanism 2. The specific grinding process is achieved by opening the clamping mechanism 7, so that the grinding belt mechanism 8 comes into contact with the inner wall of the steel pipe. At this time, the grinding belt mechanism 8 can grind the inner wall of the steel pipe. At the same time, the elastic vibration clamping plate mechanism 9 can drive the grinding belt mechanism 8 to vibrate, thereby accelerating the loosening of the debris attached to the inner wall of the steel pipe. In this way, the grinding process of the inner wall of the steel pipe is completed.

[0044] This invention, by setting up a first mounting pipe mechanism 1 and a second mounting pipe mechanism 2, enables the supply of coolant to the grinding position on the inner wall of the steel pipe and simultaneously removes impurities generated during grinding. A movable chuck mechanism 4 allows the equipment to move along the inner walls of steel pipes with different inner diameters. A pneumatic sealing mechanism 5 enables partial sealing of the steel pipe's interior and allows coolant to be supplied between the two pneumatic sealing mechanisms 5, thereby accelerating heat dissipation during grinding and simultaneously removing impurities generated during grinding. A rotating shell mechanism 6 drives the grinding belt mechanism 8 to rotate and shift, enabling rotational grinding of the inner wall of the steel pipe. A pressing mechanism 7 controls the pressure between the grinding belt mechanism 8 and the inner wall of the steel pipe. Combined with an elastic vibration clamping plate mechanism 9, the grinding belt mechanism 8 vibrates, increasing grinding intensity and improving the efficiency of grinding the inner wall of the steel pipe.

[0045] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
