Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly relates to an on-site welding device for ultra-long pipes. Background Art

[0002] Welded steel pipes refer to steel pipes with seams on the surface, which are formed by bending steel strips or steel plates into circular, square or other shapes and then welding them. The blanks used for welded steel pipes are steel plates or steel strips.

[0003] However, in the prior art, due to the gravity of the long pipes themselves and different metal properties, they are prone to slight bending, making it difficult to weld them. Precise docking is required for the welding parts to achieve better welding after welding. Moreover, when welding long pipes, if dust removal is required, a portable dust collector needs to be carried to remove dust from the welding parts, which is troublesome and laborious during the movement process. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: an on-site welding device for ultra-long pipes includes a base. A slide rail is fixedly connected to the upper surface of the base. A support device is arranged above the slide rail. There are two support devices. A positioning device is arranged between the support devices. A storage device is arranged below the positioning device. The support device includes a positioning column. A horn column is fixedly connected to the outer surface of the positioning column. A slider is slidably connected to the inner surface of the horn column. A sliding plate is rotatably connected to the outer surface of the slider. A connecting column is rotatably connected to the outer surface of the sliding plate. A rotating block is fixedly connected to the outer surface of the connecting column. A roller is rotatably connected to the inner surface of the rotating block. An activity rod is rotatably connected to the inner surface of the rotating block. A compression spring is arranged on the outer surface of the activity rod. When the pipe enters, it will push the sliding plate to move. The slider connected to the sliding plate will slide in the groove on the horn column and drive the rotatably connected connecting column to move, thereby causing the rotating block to move. Due to the action of the compression spring, the activity rod is driven to move. At the same time, the roller will support the entering steel pipe and will not affect its continued entry. At this time, the positioning column cooperates with the positioning device, and the push column drives the clamping device to clamp the pipe, so that the two ends of the entering pipe enter the position of the center of the positioning device, which is convenient for subsequent clamping.

[0005] Preferably, the positioning device includes a connecting device, above which a clamping device is arranged. A pushing column is arranged on the outer surface of the clamping device. A sliding groove is slidably connected to the outer surface of the pushing column. A fixing plate is fixedly connected to the outer surface of the sliding groove. A moving column is fixedly connected to the outer surface of the fixing plate. A baffle is fixedly connected to the outer surface of the moving column. When the pipe enters, the pushing column is moved to drive the baffle fixedly connected to the moving column to move. The connecting device plays a connecting role. In cooperation with the clamping device, when the pushing column presses the sliding inclined plate, the arc-shaped plate fixedly connected to the sliding inclined plate will press the pipe and extrude the pipe to the central position.

[0006] Preferably, the connecting device includes a sliding box. An extension rod is fixedly connected to the outer surface of the sliding box. A trapezoidal movable block is slidably connected to the outer surface of the extension rod. A trapezoidal fixed block is fixedly connected to the outer surface of the extension rod. A telescopic spring is arranged outside the trapezoidal fixed block. A blocking column is fixedly connected to the outer surface of the telescopic spring. The outer surface of the telescopic spring is fixedly connected to the inner surface of the sliding box. The outer surface of the blocking column is slidably connected to the inner surface of the sliding box. In cooperation with the connecting device, the position of the pipe can be effectively fixed, so that the two pipes are concentric and will not move randomly.

[0007] Preferably, the clamping device includes a first fixing ring. A rotating ring is slidably connected to the outer surface of the first fixing ring. A clamping device is arranged on the outer surface of the rotating ring. A sliding inclined plate is slidably connected to the inner surface of the rotating ring. An arc-shaped plate is fixedly connected to the outer surface of the sliding inclined plate. A second fixing ring is arranged around the arc-shaped plate. The inner surface of the second fixing ring is slidably connected to the outer surface of the sliding inclined plate. The outer surface of the second fixing ring is slidably connected to the outer surface of the rotating ring, so that it will not generate too much friction on the pipe when it moves, thus not affecting butt welding. At this time, the outwardly pulled support device can move along the slide rail to the end of the pipe away from the welding to implement support, thereby reducing the vibration and bending of the pipe.

[0008] Preferably, the clamping device includes a first rotating rod. A sliding groove is slidably connected to the outer surface of the first rotating rod. A second rotating rod is rotatably connected to the outer surface of the first rotating rod. A clamping plate is rotatably connected to the outer surface of the second rotating rod. By setting the clamping device, the process of clamping the pipe is fixed, so that the support device does not need to continuously apply pressure to the pushing column for clamping the pipe. After clamping, the support device can be moved to be active.

[0009] Preferably, the storage device includes a support plate. A cross plate is fixedly connected to the upper surface of the support plate. A movable ring is rotatably connected to the outer surface of the cross plate. Support rods are arranged on both sides of the movable ring. A fixing device is arranged above the support rods. The fixing device includes a push-pull ring. A connecting block is fixedly connected to the outer surface of the push-pull ring. A pressure block is rotatably connected to the inner surface of the connecting block. A first thrust rod is rotatably connected to the outer surface of the pressure block. A second thrust rod is rotatably connected to the inner surface of the first thrust rod. A fixed clamp is rotatably connected to the outer surface of the second thrust rod. The fixing device is provided to fix the support rods so that the moving columns on both sides will not return due to the gravity of the objects on the support plate. When the moving columns reach a certain position, the fixing device is provided to support the support rods, so that the stored objects will not return again after being pulled out and shown.

[0010] The beneficial effects of the present invention are as follows: 1. By providing a support device in the present invention, when two sections of pipes are welded, they are pushed in from one end of the horn column. When the pipes enter, they will push the sliding plate to move. The slider connected to the sliding plate will slide in the groove on the horn column and drive the rotatably connected connecting column to move at the same time, so that the rotating block moves. Due to the action of the compression spring, the movable rod is driven to move. At the same time, the rollers will support the entering steel pipe and will not affect its continuous entry. At this time, the positioning column cooperates with the positioning device, and the push column drives the clamping device to clamp the pipes, so that the entering positions of both ends of the pipes are the centers of the positioning device, which is convenient for subsequent clamping.

[0011] 2. By providing a positioning device in the present invention, when the pipes enter, the push column moves to drive the baffle fixedly connected to the moving column to move. A connection is achieved through the connection device. In cooperation with the clamping device, when the push column squeezes the sliding inclined plate, the arc plate fixedly connected to the sliding inclined plate will squeeze the pipes and squeeze the pipes to the central position. In cooperation with the connection device, the positions of the pipes can be effectively fixed, so that the two pipes are concentric and will not move randomly.

[0012] 3. By providing a clamping device in the present invention, after the pipes are clamped, the process of clamping the pipes is fixed by the clamping device, so that the support device does not need to continuously apply pressure to the push column for clamping the pipes. After clamping, the support device can be moved. Due to the setting of the rollers, when it moves, it will not generate too much friction on the pipes, thus not affecting butt joint and welding. At this time, the outwardly pulled support device can move along the slide rail to the end of the pipe far from the welding to provide support, thereby reducing the vibration and bending of the pipes.

[0013] 4. The present invention incorporates a storage device to house the exhaust fan within the base. After the pipes are docked and fixed, the movable columns on both sides are pulled apart, driving the support rods to separate. The separated support rods cause the rotationally connected support plate to rise. An exhaust fan can be installed within the cross plate. By pulling the movable ring, a certain amount of dust and smoke can be blocked above the welding area. A fixing device is provided to secure the support rods, preventing the movable columns on both sides from returning due to the gravitational force of the objects on the support plate. When the movable columns reach a certain position, the fixing device provides a supporting force to the support rods, ensuring that the stored objects do not return after being pulled out and revealed.

[0017] Embodiment: Please refer to Figure 1 - Figure 9 , the present invention provides a technical solution: an on-site welding device for ultra-long pipes includes a base 1. A slide rail 2 is fixedly connected to the upper surface of the base 1. A support device 3 is arranged above the slide rail 2. There are two support devices 3. A positioning device 4 is arranged between the support devices 3. A storage device 5 is arranged below the positioning device 4; The support device 3 includes a positioning column 31. A horn column 32 is fixedly connected to the outer surface of the positioning column 31. A slider 34 is slidably connected to the inner surface of the horn column 32. A sliding plate 33 is rotatably connected to the outer surface of the slider 34. A connecting column 35 is rotatably connected to the outer surface of the sliding plate 33. A rotating block 36 is fixedly connected to the outer surface of the connecting column 35. A roller 37 is rotatably connected to the inner surface of the rotating block 36. An activity rod 38 is rotatably connected to the inner surface of the rotating block 36. A compression spring 39 is arranged on the outer surface of the activity rod 38. When two sections of pipes are welded, they are pushed in from one end of the horn column 32. When the pipes enter, they will push the sliding plate 33 to move. The slider 34 connected to the sliding plate 33 will slide in the groove on the horn column 32 and drive the rotatably connected connecting column 35 to move, so that the rotating block 36 moves. Due to the action of the compression spring 39, the activity rod 38 is driven to move. At the same time, the roller 37 will support the incoming steel pipe and will not affect its continued entry.

[0018] The positioning device 4 includes a connecting device 41. A clamping device 42 is arranged above the connecting device 41. A push column 43 is arranged on the outer surface of the clamping device 42. A sliding groove 44 is slidably connected to the outer surface of the push column 43. A fixing plate 45 is fixedly connected to the outer surface of the sliding groove 44. A moving column 46 is fixedly connected to the outer surface of the fixing plate 45. A baffle 47 is fixedly connected to the outer surface of the moving column 46.

[0019] The connecting device 41 includes a sliding box 411. An extension rod 412 is fixedly connected to the outer surface of the sliding box 411. A trapezoidal movable block 413 is slidably connected to the outer surface of the extension rod 412. A trapezoidal fixed block 414 is fixedly connected to the outer surface of the extension rod 412. A telescopic spring 415 is arranged outside the trapezoidal fixed block 414. A blocking column 416 is fixedly connected to the outer surface of the telescopic spring 415. The outer surface of the telescopic spring 415 is fixedly connected to the inner surface of the sliding box 411. The outer surface of the blocking column 416 is slidably connected to the inner surface of the sliding box 411. The positioning column 31 presses the push column 43, and the push column 43 moves on the sliding groove 44. The sliding groove 44 is fixed on the fixing plate 45, and the fixing plate 45 is fixed on the moving column 46. The push column 43 drives the clamping device 42 to clamp the pipe.

[0020] The clamping device 42 includes a first fixing ring 421. A rotating ring 422 is slidably connected to the outer surface of the first fixing ring 421. A clamping device 423 is arranged on the outer surface of the rotating ring 422. A sliding inclined plate 424 is slidably connected to the inner surface of the rotating ring 422. An arc-shaped plate 425 is fixedly connected to the outer surface of the sliding inclined plate 424. A second fixing ring 426 is arranged around the arc-shaped plate 425. The inner surface of the second fixing ring 426 is slidably connected to the outer surface of the sliding inclined plate 424. The outer surface of the second fixing ring 426 is slidably connected to the outer surface of the rotating ring 422. When the pipe enters, moving the push column 43 drives the baffle 47 fixed on the moving column 46 to move. The baffle 47 pushes the sliding box 411 to move, so that the trapezoidal fixed block 414 on the extension rod 412 enters the inside of the opposite sliding box 411. Since there are holes in the sliding box 411 to accommodate the telescopic spring 415 and the blocking column 416, when the trapezoidal fixed block 414 enters, it will press the blocking column 416 to slide and then reset under the action of the telescopic spring 415, which will block the trapezoidal fixed block 414 and play a connecting role. It can only be pulled out until the trapezoidal movable block 413 also passes through the blocking column 416 after being pushed in again. Cooperating with the clamping device 42, when the push column 43 presses the sliding inclined plate 424, the arc-shaped plate 425 fixedly connected to the sliding inclined plate 424 will press the pipe and squeeze the pipe to the central position.

[0021] The clamping device 423 includes a first rotating rod 4231. A sliding groove 4232 is slidably connected to the outer surface of the first rotating rod 4231. A second rotating rod 4233 is rotatably connected to the outer surface of the first rotating rod 4231. A clamping plate 4234 is rotatably connected to the outer surface of the second rotating rod 4233. After the pipe is clamped, rotate the rotating ring 422. The rotating ring 422 that slides on the two surfaces of the first fixing ring 421 and the second fixing ring 426 will drive the first rotating rod 4231 to move. The first rotating rod 4231 moves on the sliding groove 4232, so its moving direction is restricted. When the rotating ring 422 drives the first rotating rod 4231 away, its lower end will move upward on the sliding groove 4232. When the second rotating rod 4233 rotatably connected to the lower end of the first rotating rod 4231 is pulled upward, it will pull the clamping plate 4234 to move inward. At this time, the clamping plate 4234 will clamp the sliding inclined plate 424, so that the supporting device 3 does not need to continuously apply pressure to the pushing column 43 for clamping the pipe.

[0022] The storage device 5 includes a support plate 51. A cross plate 52 is fixedly connected to the upper surface of the support plate 51. A movable ring 53 is rotatably connected to the outer surface of the cross plate 52. Support rods 54 are arranged on both sides of the movable ring 53. A fixing device 55 is arranged above the support rods 54. The fixing device 55 includes a push-pull ring 551. A connecting block 552 is fixedly connected to the outer surface of the push-pull ring 551. A pressure block 553 is rotatably connected to the inner surface of the connecting block 552. A first thrust rod 554 is rotatably connected to the outer surface of the pressure block 553. A second thrust rod 555 is rotatably connected to the inner surface of the first thrust rod 554. A fixing clip 556 is rotatably connected to the outer surface of the second thrust rod 555. By setting the fixing device 55 to fix the support rods 54, the moving columns 46 on both sides will not return due to the gravity of the objects on the support plate 51. After the moving columns 46 reach a certain position, push the push-pull ring 551 to drive the connecting block 552 to move downward to generate pressure on the pressure block 553, so that the first thrust rod 554 is driven to be squeezed and rotate, thereby driving the second thrust rod 555 to move, so that the fixing clip 556 is squeezed inward to generate a supporting effect on the support rods 54.

[0023] Working principle: During use, by setting the supporting device 3, when two sections of pipe are welded, they are pushed in from one end of the horn column 32. When the pipe enters, it will push the sliding plate 33 to move. The slider 34 connected to the sliding plate 33 will slide in the groove on the horn column 32 and drive the rotatably connected connecting column 35 to move, thereby causing the rotating block 36 to move. Due to the action of the compression spring 39, the movable rod 38 is driven to move. At the same time, the roller 37 will support the incoming steel pipe and will not affect its continued entry. At this time, the positioning column 31 cooperates with the positioning device 4. The positioning column 31 squeezes the push column 43, and the push column 43 moves on the sliding groove 44. The sliding groove 44 is fixed on the fixing plate 45, and the fixing plate 45 is fixed on the moving column 46. The push column 43 drives the clamping device 42 to clamp the pipe, so that the two ends of the incoming pipe enter at the center of the positioning device 4, which is convenient for subsequent clamping.

[0024] During use, by setting the positioning device 4, when the pipe enters, the push column 43 is moved to drive the baffle 47 fixedly connected to the moving column 46 to move. The baffle 47 pushes the sliding box 411 to move, so that the trapezoidal fixing block 414 on the extension rod 412 enters the inside of the opposite sliding box 411. Since there are holes in the sliding box 411 to accommodate the telescopic spring 415 and the blocking column 416, when the trapezoidal fixing block 414 enters, it will press the blocking column 416 to slide and then reset under the action of the telescopic spring 415, and will block the trapezoidal fixing block 414, playing a connecting role. It can only be pulled out until the trapezoidal movable block 413 also passes through the blocking column 416 after being pushed in again. Cooperating with the clamping device 42, when the push column 43 squeezes the sliding inclined plate 424, the arc plate 425 fixedly connected to the sliding inclined plate 424 will squeeze the pipe, squeezing the pipe to the central position. Cooperating with the connecting device 41, the position of the pipe can be effectively fixed, so that the two pipes are concentric and will not move randomly.

[0025] In use, by setting the clamping device 423, after the pipe is clamped, the rotating ring 422 is rotated. The rotating ring 422 that slides on the two surfaces of the first fixed ring 421 and the second fixed ring 426 will drive the first rotating rod 4231 to move. The first rotating rod 4231 moves on the chute 4232, so its moving direction is restricted. When the rotating ring 422 drives the first rotating rod 4231 away, its lower end will move upward in the chute 4232. The second rotating rod 4233 rotatably connected to the lower end of the first rotating rod 4231 will pull the clamping plate 4234 inward when being pulled upward. At this time, the clamping plate 4234 will clamp the sliding inclined plate 424, so that the supporting device 3 does not need to continuously apply pressure to the pushing column 43 for clamping the pipe. After clamping, the supporting device 3 can be moved. Due to the setting of the rollers 37, when it moves, it will not generate too much friction on the pipe, thus not affecting butt joint and welding. At this time, the supporting device 3 pulled outward can move along the slide rail 2 to the end of the pipe away from the welding to implement support, thereby reducing the vibration and bending of the pipe.

[0026] In use, the exhaust fan is received inside the base 1 by setting the receiving device 5. After the pipes are butted and fixed, the moving columns 46 on both sides are pulled apart to drive the support rods 54 to be pulled apart. The pulled support rods 54 cause the rotatably connected support plate 51 to rise. An exhaust fan can be arranged inside the cross plate 52. The movable ring 53 is pulled to block a certain amount of dust and smoke above the welding ground. The fixing device 55 is set to fix the support rods 54 so that the moving columns 46 on both sides will not return due to the gravity of the objects on the support plate 51. When the moving columns 46 reach a certain position, the push-pull ring 551 is pushed to drive the connecting block 552 to move downward to exert pressure on the pressure block 553, so that the first thrust rod 554 is driven to be squeezed and rotated, thereby driving the second thrust rod 555 to move, so that the fixed clamp 556 is squeezed inward to exert a supporting effect on the support rod 54, playing a role in preventing the received object from returning again after being pulled out.
