[0016] Furthermore, a method for using a loading and unloading device for welding a transformer oil tank, the method comprising the following steps:

[0017] S1: First, connect the connecting plate 1 with a manipulator. When the oil tank needs to be loaded, the manipulator moves the device to the top of the oil tank, and then drives the device to move downward and to the surface of the oil tank. Then, the electric push rod is started. When the electric push rod is working, its output end will move upward. When the output end of the electric push rod moves upward, it will drive the hollow plate and the connecting plate 2 to move upward. When the hollow plate moves upward, the hollow plate will pull the L plate to move;

[0018] S2: When the L plate moves, it drives the hollow frame to slide on the surface of the guide rod. When the four hollow frames slide, they will form a four-sided covering on the surface of the oil tank and clamp the oil tank;

[0019] S3: After the four hollow frames are clamped to the oil tank, the movement of the manipulator is controlled so that the device drives the oil tank to move to the welding table to complete the loading work.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the L-plate pulls the hollow frame to make it slide on the surface of the guide rod, the sliding of the hollow frame will drive the T-shaped plate to move synchronously. When the hollow frame drives the T-shaped plate to move, the T-shaped plate will slide on the surface of the raised shaft. Since the raised sliding on the surface of the raised shaft is connected to the threaded groove inside the T-shaped plate, when the T-shaped plate slides on the surface of the raised shaft, the T-shaped plate will rotate. When the T-shaped plate rotates, it will squeeze the push rod through the wave groove on its side wall. After the push rod is squeezed, it will push the sliding block to slide. When the sliding block slides, it will squeeze the trapezoidal block. After the trapezoidal block is squeezed, it will slide between the two obtuse-angle frames and squeeze the front end of the obtuse-angle frame. When the front end of the obtuse-angle frame is squeezed, the obtuse-angle frame will rotate with its middle as the center. When the obtuse-angle frame rotates, the obtuse-angle frame will push the rubber plate through the movable plate to move it forward. When the rubber plate moves forward, the rubber The plate will fit on the surface of the oil tank. At the same time, when the sliding block slides, the sliding of the sliding block will drive the rotating disk to rotate through the long rod. When the rotating disk rotates, it will push the arc plate through the middle plate to make it rotate on the side wall of the inclined plate. When the arc plate rotates, the rotation of the arc plate will drive the middle of the rubber plate to move backward through the spring shaft. When the spring shaft moves backward, the spring shaft will pull the front end of the rubber plate. The front end of the rubber plate will form a depression after being pulled, and the edge of the rubber plate will form an outward convex deformation. When the rubber plate is deformed, the contact area with the oil tank will be significantly increased, which makes the clamping force more evenly distributed on the surface of the oil tank, reducing the risk of deformation or damage of the oil tank caused by excessive local pressure. At the same time, a larger friction area will be formed on the surface of the oil tank, which helps to ensure that the oil tank will not slide or fall off easily during the clamping and transportation process, thereby improving the feeding and conveying efficiency.

[0022] 2. In the present invention, when the movement of the sliding block drives the long rod to move, the movement of the long rod will drive the rotating disk to rotate. When the rotating disk rotates, the rotation of the rotating disk will drive several square plates of its extension section to rotate synchronously. When the square plates rotate, they will periodically push the rotating frame. When the rotating frame is pushed by the square plates, the rotating frame will drive the spring disk to rotate synchronously. At the same time, when the spring plate rotates, the spring plate will push the spring disk through the connecting strip, so that the spring disk contacts the surface of the ratchet shaft. Then, when the rotating frame rotates, the rotating frame will drive the spring disk to rotate synchronously. When the spring disk rotates, it pushes the ratchet shaft, so that the ratchet shaft rotates. When the ratchet shaft rotates, it will reel in both ends of the ratchet belt. Since the two ends of the ratchet belt are entangled together, it will generate a large amount of friction with itself. At this time, under the action of friction, the ratchet belt will reel in with the rotation of the ratchet shaft, and will not produce reverse relaxation. When the ratchet belt is wrapped around the surface of the oil tank, it can apply a tightening force to the oil tank from multiple directions, which can avoid the oil tank from slipping on the surface of the rubber sheet due to the downward gravity of the oil tank itself or impurities on the surface. It can also effectively prevent the oil tank from shaking and displacing during transportation, greatly improving the stability of the clamping, ensuring the tightening effect, and improving the feeding efficiency.

[0023] 3. In the present invention, when the T-shaped plate rotates on the surface of the raised shaft along with the movement of the hollow frame, the rotation of the T-shaped plate will drive the spiral rod to rotate synchronously. When the spiral rod rotates, the rotating spiral rod will drive the insertion rod slidably connected to the surface of the spiral rod to move. When the insertion rod moves, the insertion rod can slide in the rectangular groove on the surface of the fixed sleeve. At the same time, when the insertion rod slides, the sliding insertion rod will drive the movable plate and the hollow bar to move synchronously through the cross rod. When the cross rod pushes the hollow bar to move forward, the hollow bar will be pushed outward by the rotating bar. When the hollow bar expands outward, it will extend out of the outer surface of the cross-slot plate and generate an outward pushing force on the surface of the oil tank. Force, since the adsorption mechanism is arranged on all four sides of the oil tank, when the hollow bar expands, it will also form an additional driving force on the oil tank, and at the same time, when the cross rod drives the movable plate to move, the movement of the movable plate will slide inside the piston box, and the movable plate will generate adsorption force between the inside of the piston box and the movable plate when sliding. At this time, the adsorption force will extract the gas inside the hollow bar through the connecting pipe. When the gas inside the hollow bar is extracted, it will pass through the round hole at the front end of the hollow bar to make it firmly adsorbed on the surface of the oil tank, which helps to prevent the oil tank from detaching from the square frame due to shaking, vibration or external force impact during transportation, and can improve the stability of the loading process.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the electric push rod 201 is working, its output end will move upward. When the output end of the electric push rod 201 moves upward, it will drive the hollow plate 202 and the connecting plate 203 to move upward. When the hollow plate 202 moves upward, the hollow plate 202 will pull the L plate 204 to move. When the L plate 204 moves, it will drive the hollow frame 205 to make the hollow frame 205 slide on the surface of the guide rod 103. When the four hollow frames 205 slide, they will form a four-sided covering on the surface of the oil tank and clamp the oil tank. After the four hollow frames 205 are clamped to the oil tank, by controlling the movement of the manipulator, the device drives the oil tank to move to the welding table to complete the loading work.

[0056] When the L plate 204 pulls the hollow frame 205 to slide on the surface of the guide rod 103, the sliding of the hollow frame 205 will drive the T-shaped plate 401 to move synchronously. When the hollow frame 205 drives the T-shaped plate 401 to move, the T-shaped plate 401 will slide on the surface of the raised shaft 402. Since the raised sliding surface of the raised shaft 402 is connected to the threaded groove inside the T-shaped plate 401, when the T-shaped plate 401 slides on the surface of the raised shaft 402, the T-shaped plate 401 will rotate. When the T-shaped plate 401 rotates, the wave The wave groove squeezes the push rod 404, and the push rod 404 pushes the sliding block 405 to slide after being squeezed. The sliding block 405 squeezes the trapezoidal block 502 when sliding. The trapezoidal block 502 slides between the two obtuse-angle frames 501 and squeezes the front end of the obtuse-angle frame 501 after being squeezed. When the front end of the obtuse-angle frame 501 is squeezed, the obtuse-angle frame 501 rotates with its middle as the center. When the obtuse-angle frame 501 rotates, the obtuse-angle frame 501 pushes the rubber plate 504 through the movable plate 503 to move it forward. When the rubber plate 504 moves forward, the rubber plate 504 will fit on the surface of the oil tank. At the same time, when the sliding block 405 slides, the sliding of the sliding block 405 will drive the rotating disk 505 to rotate through the long rod. When the rotating disk 505 rotates, it will push the arc plate 507 through the middle plate 508 to make it rotate on the side wall of the inclined plate 302. When the arc plate 507 rotates, the rotation of the arc plate 507 will drive the spring shaft 506 to move backward in the middle of the rubber plate 504. When the spring shaft 506 moves backward, the spring shaft 506 The front end of the rubber sheet 504 will be pulled, and the front end of the rubber sheet 504 will be concave after being pulled, and the edge of the rubber sheet 504 will be deformed to bulge outward. When the rubber sheet 504 is deformed, the contact area with the oil tank will be significantly increased, which makes the clamping force more evenly distributed on the surface of the oil tank, reducing the risk of deformation or damage to the oil tank caused by excessive local pressure. At the same time, a larger friction area will be formed on the surface of the oil tank, which helps to ensure that the oil tank will not slide or fall off easily during the clamping and transportation process, thereby improving the feeding and conveying efficiency.

[0057] When the movement of the sliding block 405 drives the long rod to move, the movement of the long rod will drive the rotating disk 505 to rotate. When the rotating disk 505 rotates, the rotation of the rotating disk 505 will drive several square plates of its extended section to rotate synchronously. When the square plates rotate, they will periodically push the rotating frame 701. When the rotating frame 701 is pushed by the square plates, the rotating frame 701 will drive the spring disk 703 to rotate synchronously. At the same time, when the spring plate 705 rotates, the spring plate 705 will push the spring disk 703 through the connecting strip 704, so that the spring disk 703 contacts the surface of the ratchet shaft 702. Then, when the rotating frame 701 rotates, the rotating frame 701 will drive the spring disk 703 to rotate synchronously. When the spring disk 703 rotates The ratchet shaft 702 is pushed to rotate the ratchet shaft 702. When the ratchet shaft 702 rotates, the two ends of the ratchet belt will be reeled in. Since the two ends of the ratchet belt are entangled together, a large amount of friction will be generated between it and itself. At this time, under the action of friction, the ratchet belt will be reeled in as the ratchet shaft 702 rotates, and no reverse relaxation will occur. When the ratchet belt is wrapped around the surface of the oil tank, a tightening force can be applied to the oil tank from multiple directions, which can prevent the oil tank from slipping on the surface of the rubber plate 504 due to the downward gravity of the oil tank itself or impurities on the surface. It can also prevent the oil tank from shaking and shifting during transportation, greatly improving the stability of the clamping, ensuring the tightening effect, and improving the feeding efficiency.

[0058] When the T-disk 401 rotates on the surface of the raised shaft 402 as the hollow frame 205 moves, the rotation of the T-disk 401 will drive the spiral rod 403 to rotate synchronously. When the spiral rod 403 rotates, the rotating spiral rod 403 will drive the insertion rod slidably connected to the surface of the spiral rod 403 to move. When the insertion rod moves, the insertion rod can slide in the rectangular groove on the surface of the fixed sleeve 601. At the same time, when the insertion rod slides, the sliding insertion rod will drive the movable disk and the hollow bar 604 to move synchronously through the cross rod 605. When the cross rod 605 pushes the hollow bar 604 to move forward, the hollow bar 604 will be pushed by the rotating bar 603 to expand outward. When the hollow bar 604 expands outward, it will extend out of the outer surface of the cross groove plate 303 and move in the oil tank. An outward thrust is generated on the surface. Since the adsorption mechanism 6 is arranged on all four sides of the oil tank, when the hollow bar 604 expands, an additional thrust is generated on the oil tank. At the same time, when the cross rod 605 drives the movable disk to move, the movement of the movable disk will slide inside the piston box 602. When the movable disk slides, an adsorption force will be generated between the inside of the piston box 602 and the movable disk. At this time, the adsorption force will extract the gas inside the hollow bar 604 through the connecting tube 606. After the gas inside the hollow bar 604 is extracted, it will be firmly adsorbed on the surface of the oil tank through the circular hole at the front end of the hollow bar 604. This helps to prevent the oil tank from detaching from the square frame due to shaking, vibration or external force impact during transportation, and can improve the stability of the loading process.
