Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen storage tank layer plate wrapping welding, and specifically relates to a hydrogen storage tank layer plate wrapping welding device and a welding method thereof. Background Art

[0002] Hydrogen storage tanks are often used for the centralized transportation of hydrogen. Due to the special physical and chemical properties of hydrogen, it is prone to accidents such as explosions. It is a dangerous transport item with extremely high transportation requirements. Therefore, it has high requirements for the rigidity of hydrogen tanks. In order to prevent the hydrogen tanks from being affected by sand and gravel splashing during transportation, the outside of the hydrogen tanks will be wrapped with multiple layers of formed steel plates before leaving the factory. Manual welds will be assisted by special clamping or tensioning devices to improve the rigidity of the hydrogen tanks.

[0003] In the prior art, after the layer plates are wrapped and bonded to the surface of the hydrogen storage tank, the layer plates and the hydrogen storage tank are often not tightly bonded due to impurities attached to the surface of the layer plates and the welding points. The impurities at the welding points prevent the layer plates from fitting perfectly, causing the layer plates to partially bulge, which seriously affects the flushness of the weld and subsequently affects the welding quality.

[0004] Therefore, we propose a welding device and a welding method for hydrogen storage tank layer wrapping to solve the above problems. Summary of the invention

Grinding equipment is provided inside the two fixed plates. A semicircular mounting plate is provided in the middle of the rear sides of the two fixed plates. A cleaning brush is provided at the front end of the outer surface of the lower end of the semicircular mounting plate. The right side wall of the moving block two on the left and the left side wall of the moving block two in the middle are provided with welding guns.

[0008] As a preferred embodiment of the present invention, a dust suction pipe is arranged at the rear end of the outer surface of the lower end of the semicircular mounting plate, an exhaust pipe is arranged in the middle of the semicircular mounting plate, and the exhaust pipe is connected to the dust suction pipe.

[0009] As a preferred embodiment of the present invention, a transfer mechanism is provided at the upper end of the base, and the transfer mechanism includes a motor 1, and the motor 1 is arranged on the right side wall of the base through a motor seat, and the power output end of the motor 1 is transmission-connected with a threaded rod 1, and the circumferential surface of the threaded rod 1 is threadedly connected with a moving block 1, and a moving plate is provided at the upper end of the moving block 1, and a lifting cylinder 1 is provided at the four corners of the upper surface of the moving plate, and the upper ends of the lifting cylinder 1 on the left and the lifting cylinder 1 on the right are both provided with arc-shaped placement plates, and a layer plate is placed between the two arc-shaped placement plates.

[0010] As a preferred embodiment of the present invention, a clamping mechanism is provided at the upper end of the base, and the clamping mechanism includes a mounting frame 2, and two mounting frames 2 are symmetrically arranged front and back, the two mounting frames 2 are arranged on the left side of the upper surface of the base, and the lower ends of the two mounting frames 2 are each provided with a lifting cylinder 2, and the upper ends of the two lifting cylinders 2 are each provided with a rotating motor, and the telescopic ends of the two rotating motors are each provided with an electric telescopic clamping plate, and the hydrogen storage tank body is clamped between the two electric telescopic clamping plates, and the hydrogen storage tank body is located between the two welding guns.

[0011] As a preferred embodiment of the present invention, the transmission mechanism includes sprocket 1, a toothed chain and sprocket 2, and two sprockets 2 are provided. The sprocket 1 is arranged on the circumferential surface of the rear end of the threaded rod 2, and the two sprockets 2 are respectively arranged on the circumferential surfaces of the rear ends of the two threaded rods 3, and the sprocket 1 and the two sprockets 2 are connected by a toothed chain transmission.

[0012] On the other hand, the present invention provides a welding method for hydrogen storage tank layer wrapping, which specifically comprises the following steps:

[0013] Step 1: First place the main body of the hydrogen storage tank between the two electric telescopic splints, then start the two electric telescopic splints, so that the two electric telescopic splints are close to each other and clamp the main body of the hydrogen storage tank between the two mounting frames 2, then place the layer plate between the two arc-shaped placement plates, and then start the motor 2 and the air pump. The motor 2 drives the threaded rod 2 and the sprocket 1 to rotate. The rotation of the sprocket 1 drives the sprocket 2 to rotate through the tooth chain, so that the threaded rod 3 rotates synchronously, and then the three groups of moving blocks 2 can move forward horizontally synchronously. The two moving blocks 2 on the right side move forward horizontally, which can drive the fixed plate and the grinding The equipment and the semicircular mounting plate move forward horizontally. When the grinding equipment moves forward, it can grind the upper surfaces of the left and right ends of the layer plate, thereby improving the cleanliness and flatness of the layer plate at this point, thereby improving the subsequent welding quality. At the same time, when the grinding equipment is grinding, the semicircular mounting plate moves forward with a cleaning brush and a dust suction pipe. The cleaning brush can clean the inner surface of the layer plate to prevent impurities from adhering to the inner surface of the layer plate and affecting the subsequent bonding effect with the outer surface of the hydrogen storage tank body. The dust suction pipe can absorb dust and impurities generated during the grinding process to prevent dust and impurities from adhering to the inner surface of the layer plate for the second time and affecting subsequent use.

[0014] Step 2: After the moving block 2 drives the grinding equipment to grind and clean the layer plate and moves to the front end, the lifting cylinder 1 is started to drive the arc-shaped placement plate to move downward for a distance to avoid the upper end of the layer plate from colliding with the lower end of the fixed mounting seat, and then the motor 1 is started, and the motor 1 drives the threaded rod 1 to rotate, so that the moving block 1 and the moving plate move horizontally to the left, and then drives the lifting cylinder 1, the arc-shaped placement plate and the layer plate to move horizontally to the left after the grinding and cleaning are completed, and stops moving after the layer plate is moved to the bottom of the hydrogen storage tank body;

[0015] Step 3: Start the lifting cylinder 1 to drive the arc-shaped placement plate and the layer plate to move vertically upward, and then fit the layer plate to the circumferential outer surface of the lower half of the hydrogen storage tank body, and then start the motor 2 in the reverse direction. At this time, when the moving block 2 moves, the welding gun installed on it works, and the grinding equipment does not work. The welding gun works to weld the upper ends of the left and right sides of the layer plate and the fitting parts of the hydrogen storage tank body. When the moving block 2 drives the welding gun to return to the initial state, the welding work of the layer plate is completed, so that the layer plate is welded to the hydrogen storage tank body, and then the motor 1 is reversed. The movable block 1 and the movable plate are driven to move to the right to the initial position. At the same time, the rotating motor drives the electric telescopic clamp and the hydrogen storage tank body to rotate 180 degrees, so that the side of the outer surface of the hydrogen storage tank body welded with the layer plate is rotated to the top, and then the above operation is repeated once, so that the other layer plate is again attached to the lower outer surface of the hydrogen storage tank body. Then, when the welding gun moves backward, the connection between the two layer plates on the hydrogen storage tank body is welded together, completing the layer plate welding and wrapping welding work of a hydrogen storage tank body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The grinding and welding mechanism can be used to grind and smooth the welding parts of the layer plates, remove impurities and protruding parts attached to the welding parts of the layer plates, and during the grinding process, the cleaning brush can also clean the inner surface of the layer plates to improve the cleanliness of the inner surface of the layer plates. Then, when the layer plates are wrapped on the surface of the hydrogen storage tank, the layer plates and the hydrogen storage tank fit more closely, and the layer plates fit more smoothly, avoiding gaps or staggered areas that affect the welding quality.

[0018] (2) Through the provided transfer mechanism and clamping mechanism, the layer plate can be automatically transferred to the surface of the hydrogen storage tank, and the layer plate can be wrapped on the surface of the hydrogen storage tank, which is convenient for subsequent welding work. There is no need for manual assistance for welding work, the operation is simple and fast, and the efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

The welding gun 407 works to weld the upper ends of the left and right sides of the layer plate 307 and the fitting parts of the hydrogen storage tank body 705. When the moving block 2 404 drives the welding gun 407 to return to the initial state, the welding work of the layer plate 307 is completed, so that the layer plate 307 is welded to the hydrogen storage tank body 705, and then the motor 1 301 The reverse rotation drives the moving block 303 and the moving plate 304 to move right to the initial position. At the same time, the rotating motor 703 drives the electric telescopic clamp 704 and the hydrogen storage tank body 705 to rotate one hundred and eighty degrees, so that the side of the outer surface of the hydrogen storage tank body 705 welded with the layer plate 307 rotates to the top, and then the above operation is repeated once, so that the other layer plate 307 is again attached to the lower outer surface of the hydrogen storage tank body 705, and then the welding gun 407 welds the connection between the two layer plates 307 on the hydrogen storage tank body 705 during the backward movement, so that the two layer plates 307 are welded together, completing the welding and wrapping welding work of the layer plates 307 of the hydrogen storage tank body 705.

4. A welding method for wrapping hydrogen storage tank layers, characterized in that: A hydrogen storage tank layer plate binding welding device applied to any one of claims 1 to 3 comprises the following steps: Step 1: first place the hydrogen storage tank body (705) between the two electric telescopic clamps (704), then start the two electric telescopic clamps (704), so that the two electric telescopic clamps (704) are close to each other and the hydrogen storage tank body (705) is clamped and fixed between the two mounting frames (701), then the layer plate (307) is placed between the two arc-shaped placement plates (306), and then the motor (6) and the air pump are started. The motor (6) drives the threaded rod (402) and the sprocket (501) to rotate, and the sprocket (501) rotates through the tooth chain (502) to drive the sprocket (503) to rotate, so that the threaded rod (403) rotates synchronously, and then the three groups of moving blocks (404) are rotated. ) can move forward horizontally synchronously, and the two right moving blocks (404) move forward horizontally, driving the fixed plate (405), the grinding device (406) and the semicircular mounting plate (408) to move forward horizontally. When the grinding device (406) moves forward, the upper surfaces of the left and right ends of the layer plate (307) are ground to improve the cleanliness and flatness of the layer plate (307) at this point, thereby improving the subsequent welding quality. At the same time, when the grinding device (406) is grinding, the semicircular mounting plate (408) moves forward with the cleaning brush (409) and the dust suction pipe (8). The cleaning brush (409) can clean the inner surface of the layer plate (307), and the dust suction pipe (8) absorbs dust and impurities generated during the grinding process; Step 2: After the moving block 2 (404) drives the grinding equipment (406) to grind and clean the layer plate (307) and moves to the front end, the lifting cylinder 1 (305) is started to drive the arc-shaped placement plate (306) to move downward for a distance, and then the motor 1 (301) is started. The motor 1 (301) drives the threaded rod 1 (302) to rotate, so that the moving block 1 (303) and the moving plate (304) move horizontally to the left, and then drives the lifting cylinder 1 (305), the arc-shaped placement plate (306) and the layer plate (307) after grinding and cleaning to move horizontally to the left, and stops moving after the layer plate (307) is moved to the bottom of the hydrogen storage tank body (705); Step 3, start the lifting cylinder 1 (305), so that it drives the arc-shaped placement plate (306) and the layer plate (307) to move vertically upward, and then the layer plate (307) is attached to the circumferential outer surface of the lower half of the hydrogen storage tank body (705), and then reversely start the motor 2 (6). At this time, when the moving block 2 (404) moves, the welding gun (407) installed thereon works, and the grinding device (406) does not work. The welding gun (407) works to weld the upper ends of the left and right sides of the layer plate (307) and the hydrogen storage tank body (705) at the joints. When the moving block 2 (404) drives the welding gun (407) to return to the initial state, the welding work of the layer plate (307) is completed, so that the layer plate (307) is welded to the hydrogen storage tank body (705), and then the motor 1 (3 01) The reverse rotation drives the moving block 1 (303) and the moving plate (304) to move rightward to the initial position. At the same time, the rotating motor (703) drives the electric telescopic clamp (704) and the hydrogen storage tank body (705) to rotate 180 degrees, so that the side of the outer surface of the hydrogen storage tank body (705) welded with the layer plate (307) rotates upward, and then the above operation is repeated once, so that the other layer plate (307) is again attached to the lower outer surface of the hydrogen storage tank body (705), and then the welding gun (407) welds the connection between the two layer plates (307) on the hydrogen storage tank body (705) during the backward movement, so that the two layer plates (307) are welded together, completing the welding and wrapping welding work of the layer plates (307) of the hydrogen storage tank body (705).
