Description

Technical Field

[0001] This invention relates to the field of tank processing technology, specifically to a welding equipment for processing tank bodies of liquid transport tank trucks. Background Technology

[0002] The welding equipment for liquid transport tanker tank body processing is a special device for welding and grinding circumferential and longitudinal seams of tank bodies. Its core lies in integrating welding and grinding functions, and achieving precise positioning and efficient operation through mechanical transmission.

[0003] The process involves workers first adjusting the position of the roller frame. Once the adjustment is complete, the tank is placed on the surface of the roller, and the tank is slowly rolled by the roller. Welding is performed during the rolling process. Since it is necessary to weld irregularly shaped tanks, insufficient contact between the roller frame and the tank can lead to unstable support, causing the tank to shake or shift during rotation. The following solutions are proposed to address these issues. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a welding device for processing the tank body of a liquid transport tanker, including a base, a roller frame slidably disposed on the top of the outer wall of the base, rollers rotatably disposed on the side wall of the roller frame, and a processing device fixedly disposed on the side wall of the base, and further including: The support mechanism is slidably mounted on the inner wall of the roller; An inflation mechanism is fixedly installed on the inner wall of the support mechanism. The braking mechanism is slidably mounted on the outer wall of the roller frame.

[0005] Preferably, the support mechanism includes: The force-applying component is slidably disposed on the inner wall of the roller; Follow component, the follow component slides and is set on the inner wall of the roller; The force-applying component is activated while the roller is rolling, and the force-applying component drives the following component to move.

[0006] Preferably, the inflation mechanism includes: A compression component is fixedly installed on the inner wall of the force-applying component; The control component is rotated and located on the inner wall of the force-applying component; In this system, as the force-applying component moves, the control component rotates accordingly.

[0007] Preferably, the braking mechanism includes: A movable component is slidably mounted on the outer wall of the roller frame; The cleaning component is slidably mounted on the outer wall of the roller frame; As the rollers roll, the cleaning components move upwards.

[0008] Preferably, the force-applying component includes a telescopic rod fixedly connected to the inner wall of the roller, an electric actuator fixedly connected to the left end of the inner wall of the roller, a sliding rod fixedly connected to the right end of the outer wall of the electric actuator, and several collision blocks fixedly connected to the side wall of the sliding rod. The tank first comes into contact with the telescopic rod, forcing the telescopic rod to compress and activating the electric actuator. Under the thrust of the electric actuator, several collision blocks move accordingly.

[0009] Preferably, the following component includes a support rod slidably connected to the inner wall of the roller, a plurality of fixing blocks are fixedly connected to the inner wall of the roller, a torsion spring is sleeved on the top of the outer wall of the fixing block, and a V-shaped rod is rotatably connected to the top of the outer wall of the fixing block; As the collision block moves, a thrust is applied to the V-shaped rod, causing the top of the outer wall of the V-shaped rod to contact the outer wall of the telescopic rod and enter the groove on the outer wall of the telescopic rod, thus restricting the telescopic rod.

[0010] Preferably, the compression assembly includes a spring fixedly connected to the inner wall of the telescopic rod, and a compression rod is fixedly connected to the inner wall of the telescopic rod; When the tank applies pressure to the telescopic rod, the compression rod contracts.

[0011] Preferably, the control component includes a swing plate rotatably connected to the through groove on the inner wall of the telescopic rod, and a leather sleeve is fixedly connected to the top of the outer wall of the telescopic rod; When the telescopic rod is compressed, it drives the swing plate to move down synchronously. When the swing plate finishes rotating, it seals the through groove on the inner wall of the telescopic rod. Under the expansion of the gas, the gas enters the interior of the sleeve, causing the sleeve to expand towards the gap.

[0012] Preferably, the moving component includes a contact block fixedly connected to the side wall of the roller, a movable plate slidably connected to the top of the outer wall of the roller frame, a spring 1 fixedly connected to the side wall of the movable plate, a triangular block fixedly connected to the end of the spring 1 away from the movable plate, and two springs 2 fixedly connected to the right end of the side wall of the movable plate. As the roller rolls, it moves the contact block, forcing the movable plate to slide. While sliding, the irregular protrusion on the top of the outer wall of the roller frame restricts the triangular block, causing the movable plate to continuously apply a pushing force to the second spring.

[0013] Preferably, the cleaning assembly includes a lifting plate slidably connected to the side wall of the roller frame, a plurality of fixed plates fixedly connected to the top of the side wall of the lifting plate, an elastic telescopic rod fixedly connected to the inner wall of the fixed plate, a grinding wheel fixedly connected to the end of the elastic telescopic rod away from the lifting plate, and a contact block fixedly connected to the side wall of the roller. When the movable plate moves, the outer inclined surface of the movable plate contacts the lifting plate, the outer wall of the grinding wheel contacts the surface of the tank, and when the roller slowly rotates at a certain angle, it drives the contact block to contact the left end of the outer wall of the movable plate, and the triangular block gets rid of the restriction of the irregular protrusion on the top of the outer wall of the roller frame.

[0014] The present invention has the following beneficial effects: (1) When the tank is placed on the roller surface, the tank first contacts the telescopic rod. While the telescopic rod is compressed, the electric actuator is activated. Under the thrust of the electric actuator, the support rod moves upward. While the support rod moves upward, the V-shaped rod rotates, so that the top of the outer wall of the V-shaped rod contacts the outer wall of the telescopic rod and enters the slot at the outer wall of the telescopic rod, thus completing the restriction of the telescopic rod. The above components effectively increase the contact area between the roller and the tank, and at the same time improve the friction of the contact surface, reducing the risk of displacement due to unstable support.

[0015] (2) When the tank applies pressure to the telescopic rod, the telescopic rod is compressed and drives the fixed shaft to move down synchronously. When the swing plate finishes rotating, the through groove on the inner wall of the telescopic rod is sealed. At this time, during the compression of the internal space of the telescopic rod, gas is generated inside the telescopic rod and enters the inside of the sleeve. The sleeve gradually expands under the entry of gas. Facing the compression of the tank, the sleeve expands towards the gap. Since there is still a gap at the bottom of the tank, it cannot fully contact the surface of the roller. The above-mentioned components inflate the sleeve to make it expand and fully contact the bottom of the tank.

[0016] (3) When the telescopic rod loses pressure, it moves upward by the elastic force of the spring. During the upward movement, the swing plate moves upward as well. When it moves to the highest point, it gets rid of the restriction of the compression rod and completes the reset by the elastic force of its own torsion spring, returning to the initial horizontal position. At this time, the through groove in the inner wall of the telescopic rod is opened, and the gas inside the sleeve and the telescopic rod is discharged through the groove. The gas pressure is released in time by the above components, which effectively avoids deformation of the telescopic rod due to excessive gas pressure, and at the same time provides sufficient space for the next compression.

[0017] (4) In this invention, while the roller is rolling, the contact block is moved, which forces the movable plate to slide. While sliding, it contacts the lifting plate, which forces the lifting plate to move upward through the inclined plane. As the upward movement continues, the grinding wheel applies pressure to the elastic telescopic rod and contacts the surface of the tank. The above components ensure that the welding area is polished after welding is completed at intervals, while effectively avoiding continuous polishing of the tank, which may prematurely remove the surface metal on the weld before it is fully cooled, and alleviate the difficulty of installation or poor sealing caused by weld protrusion.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-10 This invention relates to a welding device for processing the tank body of a liquid transport tanker truck, comprising a base 13, a roller frame 14 slidably disposed on the top of the outer wall of the base 13, rollers 15 rotatably disposed on the side wall of the roller frame 14, and a processing device 16 fixedly disposed on the side wall of the base 13, and further comprising: Support mechanism 1 is slidably disposed on the inner wall of roller 15; Inflation mechanism 2 is fixedly installed on the inner wall of support mechanism 1; Braking mechanism 3 is slidably mounted on the outer wall of roller frame 14.

[0023] Supporting mechanism 1 includes: Force application component 11 is slidably disposed on the inner wall of roller 15; follower component 12 is slidably disposed on the inner wall of roller 15. First, the staff adjusts the position of the roller frame 14. After the adjustment is completed, the can is placed on the surface of the roller 15. At this time, the staff adjusts the processing device 16. When the can is placed on the surface of the roller 15, the roller 15 is started. The roller 15 drives the can to roll slowly. While rolling, the processing device 16 welds the surface of the can. At the same time as the roller 15 rolls, the force application component 11 is started, which drives the following component 12 to move.

[0024] Inflatable mechanism 2 includes: Compression component 21 is fixedly installed on the inner wall of force application component 11; Control component 22 is rotatably disposed on the inner wall of force application component 11; In this process, pressure is applied to the compression component 21 while the force application component 11 moves, forcing the compression component 21 to change, and the control component 22 rotates in accordance with the change of the compression component 21.

[0025] Braking mechanism 3 includes: The moving component 31 is slidably disposed on the outer wall of the roller frame 14; the cleaning component 32 is slidably disposed on the outer wall of the roller frame 14. As the roller 15 rolls, it drives the moving component 31 to move, and as the moving component 31 moves, it drives the cleaning component 32 to move upward.

[0026] Example 2, please refer to Figures 3-13 The present invention is a welding equipment for processing the tank body of a liquid transport tanker. Based on Example 1, the force application component 11 includes a telescopic rod 111 fixedly connected to the inner wall of the roller 15, an electric push rod 112 fixedly connected to the left end of the inner wall of the roller 15, a sliding rod 113 fixedly connected to the right end of the outer wall of the electric push rod 112, and a plurality of collision blocks 114 fixedly connected to the side wall of the sliding rod 113. The process begins with the workers adjusting the position of the roller frame 14. Once the adjustment is complete, the can is placed on the surface of the roller 15. At this point, the workers adjust the processing device 16. When the can is placed on the surface of the roller 15, the roller 15 is activated, causing the can to roll slowly. During the rolling process, the processing device 16 welds the surface of the can. When the can is placed on the surface of the roller 15, it first comes into contact with the telescopic rod 111, forcing the telescopic rod 111 to be compressed. While the telescopic rod 111 is being compressed, the electric push rod 112 is activated. Under the thrust of the electric push rod 112, the sliding rod 113 slides, and several collision blocks 114 move accordingly.

[0027] The following component 12 includes a support rod 121 that is slidably connected to the inner wall of the roller 15. Several fixing blocks 122 are fixedly connected to the inner wall of the roller 15. A torsion spring 123 is sleeved on the top of the outer wall of the fixing block 122. A V-shaped rod 124 is rotatably connected to the top of the outer wall of the fixing block 122. As the collision block 114 moves, it exerts a thrust on the support rod 121, forcing the support rod 121 to move upward. As the support rod 121 moves upward, it exerts a thrust on the V-shaped rod 124, causing the V-shaped rod 124 to rotate. As it rotates, it applies pressure to the torsion spring 123, forcing the torsion spring 123 to be compressed. As the V-shaped rod 124 rotates, the telescopic rod 111 is compressed, causing the top of the outer wall of the V-shaped rod 124 to contact the outer wall of the telescopic rod 111 and enter the groove on the outer wall of the telescopic rod 111, thus completing the restriction of the telescopic rod 111.

[0028] The compression assembly 21 includes a spring 211 fixedly connected to the inner wall of the telescopic rod 111, and a compression rod 212 fixedly connected to the inner wall of the telescopic rod 111. When the tank applies pressure to the telescopic rod 111, the telescopic rod 111 is compressed and exerts pressure on the spring 211, forcing the spring 211 to compress. At the same time, pressure is applied to the compression rod 212, causing the compression rod 212 to contract.

[0029] The control component 22 includes a swing plate 221 rotatably connected to the through groove on the inner wall of the telescopic rod 111, and a leather sleeve 222 is fixedly connected to the top of the outer wall of the telescopic rod 111. When the telescopic rod 111 is compressed, it drives the fixed shaft 221 to move downwards synchronously. During the downward movement of the fixed shaft 221, it contacts the top of the compression rod 212 and rotates under the restriction of the compression rod 212, generating pressure on the torsion spring on the inner wall. This forces the torsion spring to compress and accumulate potential energy. When the swing plate 221 finishes rotating, it completes the sealing of the through groove on the inner wall of the telescopic rod 111. At this time, during the compression of the internal space of the telescopic rod 111, gas is generated inside the telescopic rod 111. Under the expansion of the gas, it enters the interior of the sleeve 222 through the slot at the top of the outer wall of the telescopic rod 111, causing the sleeve 222 to gradually expand under the entry of gas. Facing the compression of the tank, the sleeve 222 expands towards the gap. If the surface of the tank is relatively flat and smooth, the generated gas will exert a thrust on the swing plate 221 during compression, causing the swing plate 221 to rotate.

[0030] The moving component 31 includes a contact block 311 fixedly connected to the side wall of the roller 15, a movable plate 312 slidably connected to the top of the outer wall of the roller frame 14, a spring 313 fixedly connected to the side wall of the movable plate 312, a triangular block 314 fixedly connected to the end of the spring 313 away from the movable plate 312, and two springs 315 fixedly connected to the right end of the side wall of the movable plate 312. As the roller 15 rolls, it drives the contact block 311 to move. Since the roller rotates slowly, after a certain welding time, the contact block 311 collides with the movable plate 312, forcing the movable plate 312 to slide. While sliding, the first spring 313 and the triangular block 314 slide. At the same time, the second spring 315 is pushed by the movable plate 312 and compressed, accumulating potential energy. During the movement of the triangular block 314, it contacts the irregular protrusion on the top of the outer wall of the roller frame 14, so that the triangular block 314 exerts a pushing force on the first spring 313. When the movable plate 312 stops moving for the first time, the irregular protrusion on the top of the outer wall of the roller frame 14 completes the restriction of the triangular block 314, so that the movable plate 312 continues to exert a pushing force on the second spring 315.

[0031] The cleaning assembly 32 includes a lifting plate 321 slidably connected to the side wall of the roller frame 14. Several fixing plates 322 are fixedly connected to the top of the side wall of the lifting plate 321. An elastic telescopic rod 323 is fixedly connected to the inner wall of the fixing plate 322. A grinding wheel 324 is fixedly connected to the end of the elastic telescopic rod 323 away from the lifting plate 321. A contact block 325 is fixedly connected to the side wall of the roller 15. When the movable plate 312 moves, the inclined outer wall of the movable plate 312 contacts the lifting plate 321, forcing the lifting plate 321 to move upward through the inclined surface. Simultaneously, the lifting plate 321 moves upward, causing the fixed plate 322 to move upward as well. The elastic telescopic rod 323 and the grinding wheel 324 follow suit. Before the upward movement stops, the outer wall of the grinding wheel 324 contacts the surface of the tank. As the upward movement continues, the grinding wheel 324 applies pressure to the elastic telescopic rod 323, causing the elastic telescopic rod 323 to be compressed. This results in unevenness on the surface of the tank, and the grinding wheel 324 compresses the elastic telescopic rod 323. The spring force ejects the grinding wheel 324, keeping its outer wall in contact with the surface of the tank. As the roller 15 slowly rotates at a certain angle, it causes the contact block 325 to contact the left end of the outer wall of the movable plate 312. Since the contact block 325 is longer than the contact block 311, the movable plate 312 is forced to move to the right again. When it stops, the triangular block 314 breaks free from the restriction of the irregular protrusion on the top of the outer wall of the roller frame 14 and is ejected outward by the elastic force of the spring 313. At this time, the movable plate 312 gradually returns to its original position by the elastic force of the spring 315, and the triangular block 314 completes its return to its original position along the groove on the top of the outer wall of the roller frame 14.

[0032] One specific application of this embodiment is as follows: the worker first adjusts the position of the roller frame 14. After the adjustment is completed, the can is placed on the surface of the roller 15. At this time, the worker adjusts the processing device 16. When the can is placed on the surface of the roller 15, the roller 15 is started. The roller 15 drives the can to roll slowly. While rolling, the processing device 16 welds the surface of the can.

[0033] To address the issue of unstable support during tank welding, particularly when welding irregularly shaped tanks, insufficient contact between the roller frame and the tank can lead to wobbling or shifting of the tank during rotation. This results in uneven stress on the weld pool, causing defects such as inconsistent weld width, excessive weld reinforcement, or incomplete fusion. To address this, when the tank is placed on the roller 15 surface, it first contacts the telescopic rod 111, forcing it to compress. Simultaneously, the electric actuator 112 is activated. Under the thrust of the electric actuator 112, the sliding rod 113 slides, and several collision blocks 114 move accordingly. As the collision blocks 114 move, they exert a thrust on the support rod 121, forcing it to move upwards. This upward movement of the support rod 121 also applies a thrust to the V-shaped rod 124, causing the V-shaped rod... When V-shaped rod 124 rotates, it applies pressure to torsion spring 123, forcing it to compress. Simultaneously, as V-shaped rod 124 rotates, telescopic rod 111 is compressed, causing the top of the outer wall of V-shaped rod 124 to contact the outer wall of telescopic rod 111 and enter the groove on the outer wall of telescopic rod 111, thus restricting telescopic rod 111. At this time, the top of the outer wall of telescopic rod 111 is in stable contact with the tank surface and generates friction on the tank surface during rolling. When the tank rotates a certain angle and is about to contact the next set of telescopic rods 111, electric actuator 112 retracts inward. Upon contact, electric actuator 112 extends again. These components effectively increase the contact area between roller 15 and the tank, while also increasing the friction of the contact surface and reducing the risk of displacement due to unstable support.

[0034] Utilizing the compression characteristics of the telescopic rod 111, when the tank applies pressure to the telescopic rod 111, the compression of the telescopic rod 111 generates pressure on the spring 211, forcing the spring 211 to compress. Simultaneously, pressure is applied to the compression rod 212, causing it to contract. As the telescopic rod 111 is compressed, it drives the fixed shaft 221 to move downwards synchronously. During the downward movement of the fixed shaft 221, it contacts the top of the compression rod 212 and rotates under the constraint of the compression rod 212, generating pressure on the torsion spring on the inner wall. This forces the torsion spring to compress and accumulate potential energy. When the swing plate 221 has finished rotating, the sealing of the through groove on the inner wall of the telescopic rod 111 is completed. During the compression process of the internal space of the telescopic rod 111, gas is generated inside the telescopic rod 111. Under the expansion of the gas, it enters the interior of the sleeve 222 through the slot at the top of the outer wall of the telescopic rod 111, causing the sleeve 222 to gradually expand under the influx of gas. Facing the compression of the tank, the sleeve 222 expands towards the gap. If the surface of the tank is relatively flat and smooth, the generated gas will exert a pushing force on the swing plate 221 during compression, causing the swing plate 221 to rotate. Since there is still a gap at the bottom of the tank, it cannot fully contact the surface of the roller. By inflating the sleeve 222 with the above-mentioned components, it expands and fully contacts the bottom of the tank.

[0035] Utilizing the characteristic that the fixed shaft 221 rotates under the constraint of the compression rod 212, when the telescopic rod 111 loses pressure, it moves upward by the elastic force of the spring 211. During the upward movement, the swing plate 221 moves upward as well. When it reaches the highest point, it breaks free from the constraint of the compression rod 212 and completes the reset by the elastic force of its own torsion spring, returning to the initial horizontal position. At this time, the through groove in the inner wall of the telescopic rod 111 is opened, and the gas inside the sleeve 222 and the telescopic rod 111 is discharged through the groove. When the internal pressure continues to rise and there is no pressure relief channel, the telescopic rod 111 may deform or rupture due to being unable to withstand the pressure. The above-mentioned components release the air pressure in time, effectively preventing the telescopic rod 111 from deforming due to excessive air pressure, and at the same time providing sufficient space for the next compression.

[0036] Utilizing the rolling characteristic of the roller 15, as the roller 15 rolls, it drives the contact block 311 to move. Since the roller's rotation speed is relatively slow, after a certain welding time, the contact block 311 collides with the movable plate 312, forcing the movable plate 312 to slide. Simultaneously, the sliding causes the first spring 313 and the triangular block 314 to slide. At the same time, the second spring 315 is pushed by the movable plate 312 and compressed, accumulating potential energy. During the movement of the triangular block 314, it contacts the irregular protrusion at the top of the outer wall of the roller frame 14, causing the triangular block 314 to exert a pushing force on the first spring 313. Meanwhile, the contact block 311... When the roller frame 14 stops moving for the first time, the irregular protrusion on the top of the outer wall restricts the triangular block 314, causing the movable plate 312 to continuously apply a pushing force to the spring 315. When the movable plate 312 moves, the inclined surface of the outer wall of the movable plate 312 contacts the lifting plate 321, forcing the lifting plate 321 to move upward through the inclined surface. As the lifting plate 321 moves upward, it drives the fixed plate 322 to move upward. The elastic telescopic rod 323 and the grinding wheel 324 follow and move upward. Before the upward movement stops, the outer wall of the grinding wheel 324 contacts the surface of the tank. As the upward movement continues, the grinding wheel 324 applies pressure to the elastic telescopic rod 323, causing the elastic... When the telescopic rod 323 is compressed, unevenness appears on the tank surface. Simultaneously, the grinding wheel 324 is ejected by the elastic force of the telescopic rod 323, maintaining contact between the outer wall of the grinding wheel 324 and the tank surface. After welding, the weld metal accumulates above the base material surface, forming a protrusion. Simultaneously, the high welding temperature causes chromium loss on the stainless steel surface, creating a chromium-depleted zone that loses its original corrosion resistance. If the oxide scale is not removed by grinding, this area will become the starting point for pitting and crevice corrosion. The aforementioned components ensure that the welded area is ground at intervals after welding, effectively avoiding continuous grinding of the tank. Premature removal of surface metal from the weld before it has fully cooled can alleviate installation difficulties or poor sealing caused by weld protrusions. When the roller 15 slowly rotates at a certain angle, it causes the contact block 325 to contact the left end of the outer wall of the movable plate 312. Since the contact block 325 is longer than the contact block 311, the movable plate 312 is forced to move to the right again. When it stops, the triangular block 314 gets rid of the restriction of the irregular protrusion at the top of the outer wall of the roller frame 14 and pops outward by the elastic force of the spring 313. At this time, the movable plate 312 gradually returns to its original position by the elastic force of the spring 315, and the triangular block 314 completes its return to its original position along the groove at the top of the outer wall of the roller frame 14.
