A reinforcing steel bar welding device for civil engineering

Abstract

This application discloses a steel bar welding device for civil engineering, belonging to the field of steel bar welding technology. The device includes a body, with a welding device mounted on the inner side of the body. Two sets of hollow tubes are rotatably connected to both ends of the inner side of the body, extending through the outer side of the body. A cavity is formed on the inner side of the body, and a motor is mounted inside the cavity. In this application, after placing two sets of steel bars into the two sets of hollow tubes, the output end of the motor rotates in the forward direction, allowing the steel bars to be clamped and aligned by a clamping assembly. Simultaneously, a second push rod enters the rotation range of a first push rod, enabling the first push rod to push the second push rod, causing the hollow tubes to rotate. This causes the two sets of steel bars to rotate synchronously, allowing the welding device to weld the outer periphery of the two sets of steel bars, thus improving welding efficiency. When the motor output end rotates in the reverse direction, the steel bars stop rotating, and the clamping assembly releases its grip on the steel bars.

Description

Technical Field

[0001] This invention belongs to the field of steel bar welding technology, specifically relating to a steel bar welding device for civil engineering. Background Technology

[0002] Reinforcing bar welding is a crucial process in civil engineering construction. Its welding quality directly affects the overall mechanical properties and durability of reinforced concrete structures, and it is widely used in reinforced concrete components of high-rise buildings, bridges, tunnels, nuclear power plants, and other projects. With the continuous advancement of infrastructure construction in my country, increasingly higher demands are being placed on the quality, efficiency, and automation level of reinforcing bar welding.

[0003] Chinese Patent CN116652472A, published on August 29, 2023, discloses a rebar welding device, including a base plate, an auxiliary structure disposed on the top of the base plate, and a support structure disposed on the top of the base plate. The auxiliary structure includes: four support frames installed on the top of the base plate, clearance openings on the side of each support frame, a lower fixing frame and an upper fixing frame disposed on the top of the support frame for clamping and fixing the rebar, and multiple lifting ports are opened on the end faces of both the lower fixing frame and the upper fixing frame. Limiting blocks are installed on the top of the upper fixing frame and on the top surface of the lifting ports, and lifting rods are rotatably connected to the bottom ends of the multiple limiting blocks. The bottom ends of the multiple lifting rods pass through the lifting ports opened on the lower fixing frame and the upper fixing frame. Threads are provided on the outer periphery of each lifting rod. A fixing plate is welded to the outer side of the support frame. When the above-mentioned equipment is in operation, the operator needs to weld the steel bars at different angles, which makes it difficult for the operator to weld the steel bars evenly during the welding process. After welding, the weld slag adheres to the surface of the steel bars. In a humid environment, the residual weld slag is prone to absorbing moisture, which accelerates the rusting of the steel bar joint area and reduces the structural life of the steel bars.

[0015] The advantages of this application are: (1) In this application, after the two sets of steel bars are placed into the two sets of hollow tubes respectively, the output end of the motor is rotated in the forward direction so that the steel bars can be clamped and centered by the clamping assembly. At the same time, the push rod 2 enters the rotation range of the push rod 1 so that the push rod 1 can push the push rod 2 to rotate the hollow tube, thereby making the two sets of steel bars rotate synchronously, so that the welder can weld the periphery of the two sets of steel bars to improve the welding efficiency. When the output end of the motor rotates in the reverse direction, the steel bars stop rotating and the clamping assembly ends the clamping of the steel bars.

[0016] (2) In this application, when the motor output end rotates in the reverse direction, the gear two drives the push block, which pushes the irregular extrusion block to move towards the irregular long plate, so that the irregular long plate moves upward and the striking block can move towards the reinforcing bar to achieve the purpose of striking the reinforcing bar, so that the slag on the surface of the reinforcing bar weld is shaken off. This facilitates observation of the actual situation at the weld and avoids the slag absorbing moisture in a humid environment, which would cause the reinforcing bar joint area to rust and thus seriously affect the structural life.

[0017] (3) In this application, when the output end of the motor rotates in the forward direction, the extrusion rod drives the linkage rod, causing the fixed rod to press down on the telescopic plate, so that the shielding plate gradually descends to prevent welding slag from splashing, avoid burns and fires, and facilitate the operator's observation. When the output end of the motor rotates in the reverse direction, the shielding plate returns to its original position. Attached Figure Description

A motor 101 is installed inside the cavity 300. A rotating rod 102 is installed at the output end of the motor 101. A push plate 103 is fixedly connected to the outer side of the rotating rod 102. A moving plate 104 is slidably connected to the inner side of the cavity 300. A limit assembly 105 is installed inside the cavity 300.

A shaped extrusion rod 202 is slidably connected to the bottom of the cavity 300 and inside the machine body 100. A shaped extrusion plate 203 is hinged to the right side of the shaped extrusion rod 202. By setting the shaped extrusion plate 203, when the push plate 103 rotates around the rotating rod 102 in the forward direction, the shaped extrusion plate 203 will not move.

By setting the limit rod 209, after the limit rod 1 201 squeezes the limit rod 209, the limit rod 209 can limit the limit rod 1 201. A spring 210 is fixedly connected to the machine body 100. A lifting rod 211 is fixedly connected below the limiting rod 209. The lifting rod 211 is in contact with the irregular extrusion rod 202. The sides of the lifting rod 211 and the irregular extrusion rod 202 that are in contact with each other are both set as bevels. The sides of the limiting rod 101 and the limiting rod 209 that face each other are both set as arc structures. A slide groove 106 is opened on the inner side of the machine body 100. An extrusion rod 107 is slidably connected on the inner side of the machine body 100 and above the slide groove 106. The extrusion rod 107 is fixedly connected above the moving plate 104. A fixing plate 108 is fixedly connected on the inner side of the machine body 100. Multiple sets of springs 109 are fixedly connected between the fixing plate 108 and the extrusion rod 107. Both sides of the pressure rod 107 are slidably connected to a moving platform 110. An extension plate 112 is fixedly connected to the outer side of the moving platform 110. A fixing plate 111 is fixedly connected to the inner side of the machine body 100. A spring 113 is fixedly connected between the fixing plate 111 and the extension plate 112. A transmission plate 123 is fixedly connected above the moving platform 110. A gear 116 is rotatably connected to the inner side of the machine body 100 and the outer side of the hollow tube 400. A telescopic ring 117 is fixedly connected to the outer side of the gear 116 and the outer side of the hollow tube 400. An annular groove is provided above the transmission plate 123. A corresponding ring is fixedly connected to the outer side of the telescopic ring 117. The ring is rotatably connected to the inner side of the annular groove. By setting the transmission plate 123...The transmission plate 123 can drive the telescopic ring 117 to move, and the telescopic ring 117 can rotate above the transmission plate 123. The telescopic ring 117 is rotatably connected above the transmission plate 123. A push rod 118 is fixedly connected to the outer side of the telescopic ring 117, and a push rod 119 is fixedly connected to the outer side of the hollow tube 400. The extrusion rod 107 is in contact with the moving platform 110. The side of the extrusion rod 107 that is in contact with the moving platform 110 is set as an inclined surface. The ends of the push rod 118 and the push rod 119 that are close to each other are set as an arc structure. Two sets of gears 115 are rotatably connected to the inner side of the machine body 100. Gear 115 meshes with gear 116. A rotating plate 114 is fixedly connected to the inner side of gear 115. Rotating plate 114 extends through the outer side of the machine body 100. A rotating rod 102 extends through the machine body 100. Rotating plates 121 are fixedly connected to both sides of the rotating rod 102 and to the outer side of the machine body 100. A transmission rod 122 is fixedly connected between rotating plate 121 and rotating plate 114. By fixing the transmission rod 122 to the same end of rotating plate 114 and rotating plate 121, rotating plate 114 and rotating plate 121 can rotate synchronously via the transmission rod 122. The outer side of the hollow tube 400 is equipped with... The system is equipped with a clamping assembly 124, which includes a rectangular plate 301 fixedly connected to the top of the moving platform 110. A slip ring 302 is slidably connected to the outer side of the hollow tube 400. An annular groove is formed on the top of the rectangular plate 301. A corresponding circular ring is fixedly connected to the outer side of the slip ring 302, and the circular ring is rotatably connected to the inner side of the annular groove. By setting the rectangular plate 301, the rectangular plate 301 can drive the slip ring 302 to move, and the slip ring 302 can rotate above the rectangular plate 301. The slip ring 302 is rotatably connected above the rectangular plate 301. A movable ring 303 is slidably connected to the outer side of the hollow tube 400. Multiple sets of springs 304 are fixedly connected between the movable ring 303 and the sliding ring 302. Four sets of extrusion plates 305 are fixedly connected to the outer side of the movable ring 303. Four sets of clamping blocks 306 are slidably connected to the inner side of the hollow tube 400. The distance between the sliding ring 302 and the movable ring 303 is less than the horizontal distance between push rod 118 and push rod 219, allowing the four sets of clamping blocks 306 to clamp the reinforcing bars before the hollow tube 400 rotates. The clamping blocks 306 are in contact with the extrusion plates 305, and the sides of the clamping blocks 306 and extrusion plates 305 that are in contact with each other are all set as inclined surfaces.

[0022] In practical use, the above-mentioned equipment is first used by placing two steel bars into the two sets of hollow tubes 400 and fitting them together. Then, the output end of the motor 101 is rotated forward, causing the motor 101 to drive the rotating rod 102 to rotate counterclockwise. The rotating rod 102 then drives the push plate 103 to rotate counterclockwise around the rotating rod 102, allowing the push plate 103 to push the moving plate 104 forward. The moving plate 104 then drives the limiting rod 201 forward, allowing the limiting rod 201 to press the limiting rod 209, causing the limiting rod 209 to move upward. As the limiting rod 201 continues to move forward, the limiting rod 209 moves downward due to the elastic force of the spring 210, thus limiting the limiting rod 201 and subsequently moving the moving plate 104. The limit switch is activated, and simultaneously, the moving plate 104 drives the pressing rod 107 forward, causing the pressing rod 107 to stop blocking the two sets of moving platforms 110. This allows the two sets of moving platforms 110 to gradually move closer together under the elastic force of spring 113. The moving platforms 110 can then drive the transmission plate 123 and the rectangular plate 301 to move together. The transmission plate 123 drives the telescopic ring 117, which in turn drives the push rod 118. This causes the push rod 119 to enter the moving range of the push rod 118, causing the rectangular plate 301 to drive the slip ring 302 towards the clamping block 306. The slip ring 302 then compresses the multiple sets of springs 304, which in turn push the movable ring 303. The movable ring 303 then drives the pressing plate 305, causing the pressing plate... 305 can compress the clamping block 306, allowing multiple sets of clamping blocks 306 to clamp and center the reinforcing bars. Simultaneously, the rotating rod 102 drives the rotating plate 121 to rotate counterclockwise, which in turn drives the transmission rod 122 to move. The transmission rod 122 then drives the rotating plate 114 to rotate, which in turn drives the gear 115 to rotate counterclockwise. The gear 115 then drives the gear 116 to rotate, which in turn drives the telescopic ring 117 to move. The telescopic ring 117 then drives the push rod 118 to move, which in turn pushes the push rod 119, causing the push rod 119 to rotate the hollow tube 400. This causes the two sets of reinforcing bars to rotate synchronously. When the two sets of reinforcing bars rotate synchronously, the welding machine 200 is activated. Welding of the reinforcing bars is performed. When welding is completed, the welding machine 200 is turned off, causing the output end of the motor 101 to rotate in the reverse direction. This causes the motor 101 to drive the rotating rod 102 to rotate clockwise, which in turn causes the push plate 103 to push the shaped extrusion plate 203. The shaped extrusion plate 203 then moves the shaped extrusion rod 202 towards the lifting rod 211, causing the shaped extrusion rod 202 to press against the lifting rod 211. This causes the lifting rod 211 to move upward, which in turn causes the second limiting rod 209 to move upward. The second limiting rod 209 then stops limiting the first limiting rod 201. When the push plate 103 stops pushing the shaped extrusion plate 203, the shaped extrusion plate 203 returns to its original position due to the elastic force of the fourth spring 207. The second limiting rod 209 stops limiting the first limiting rod 201.The clamping rod 107 can return to its original position by the elastic force of the spring 109, causing the clamping rod 107 to press against the two sets of moving platforms 110, which then return to their original positions, thus ending the clamping of the reinforcing bar. When the slag removal process is complete, the motor 101 shuts off.

[0023] Example 2, as Figure 1 , Figure 9 , Figure 10 As shown, based on Embodiment 1, a support plate 401 is fixedly connected to the inner side of the machine body 100 and above the extrusion rod 107. A shaped support block 402 is fixedly connected above the support plate 401. Multiple sets of openings are made on the inner side of the shaped support block 402, allowing welding slag on the reinforcing bar to fall through these openings, preventing the slag from accumulating above the shaped support block 402. Guide plates 403 are fixedly connected to both sides of the shaped support block 402. An extrusion block 404 is slidably connected above the guide plates 403. A sliding rod 405 is fixedly connected to the outer side of the extrusion block 404. A fixing block 406 is fixedly connected above the steel bar. A sliding rod 405 passes through the fixing block 406. A striking block 418 is fixedly connected to the outside of the sliding rod 405 and the outside of the fixing block 406. By setting the striking block 418, the welding slag attached to the steel bar will be shaken off when the striking block 418 strikes the steel bar. The extrusion block 408 and the extrusion block 404 are in contact with each other. The side of the extrusion block 408 that is in contact with the extrusion block 404 is set as a slope. The side of the striking block 418 near the irregular support block 402 is set as an arc structure. The extrusion block 404 and the fixing block 406 are fixedly connected. There is a spring 407. Two sets of round rods 409 are slidably connected to the inner side of the support plate 401. An extrusion block 408 is fixedly connected above the round rods 409. A lifting plate 410 is fixedly connected below the two sets of round rods 409. A spring 411 is fixedly connected between the lifting plate 410 and the support plate 401. An irregularly shaped long plate 417 is fixedly connected below the lifting plate 410. The irregularly shaped long plate 417 is slidably connected to the inner side of the machine body 100. A push block 413 is fixedly connected to the outer side of the gear 115. Irregularly shaped extrusion blocks 414 are slidably connected to both ends of the inner side of the machine body 100. By setting irregularly shaped extrusion blocks... When the motor 101 rotates in the forward direction, the pusher 413 pushes the irregularly shaped extrusion block 414 away from the irregularly shaped long plate 417. When the motor 101 rotates in the reverse direction, the pusher 413 pushes the irregularly shaped extrusion block 414 to press the irregularly shaped long plate 417. Triangular block one and triangular block two are fixedly connected to the upper left and right sides of the irregularly shaped extrusion block 414, respectively. Triangular block one is in contact with the irregularly shaped long plate 417, and triangular block two is on the moving path of the pusher 413. Fixed plates 415 are fixedly connected to both ends of the inner side of the machine body 100. A spring 416 is fixedly connected between the fixed plate 415 and the irregularly shaped extrusion block 414.

[0024] In practical use, when the output end of motor 101 rotates in the reverse direction, gear 2 115 rotates clockwise, causing gear 2 115 to drive push block 413 to rotate clockwise around gear 2 115. This allows push block 413 to push the irregularly shaped extrusion block 414, causing the irregularly shaped extrusion block 414 to move towards the irregularly shaped long plate 417. This allows the irregularly shaped extrusion block 414 to extrude the irregularly shaped long plate 417, causing the irregularly shaped long plate 417 to move upward. This allows the irregularly shaped long plate 417 to drive the lifting plate 410 to move upward, which in turn drives the round rod 409 to move upward. This allows the round rod 409 to drive the extrusion block 2 408 to move upward, allowing the extrusion block 2 408 to... The compression block 404 is pressed and moved toward the fixed block 406, which in turn moves the sliding rod 405. The sliding rod 405 then moves the striking block 418, which strikes the reinforcing bar to dislodge the weld slag from the weld surface. This facilitates observation of the weld and prevents the weld slag from absorbing moisture in a humid environment, which could lead to rust in the joint area of ​​the reinforcing bar and severely affect the structural lifespan. After the push block 413 passes the irregular compression block 414, the irregular compression block 414 can return to its original position via the spring 416, allowing the push block 413 to repeatedly push the irregular compression block 414.

[0025] Example 3, as Figure 2 , Figure 11 , Figure 12 As shown, based on Embodiment 1 or Embodiment 2, a baffle plate 501 is slidably connected to the inner side of the machine body 100. By setting the baffle plate 501, the baffle plate 501 can block the splashing welding slag. An opening 502 is provided on the top of the machine body 100. A rotating rod 503 is rotatably connected to the inner side of the machine body 100 and to the inner side of the opening 502. A telescopic plate 504 is rotatably connected to the outer side of the rotating rod 503. The telescopic plate 504 is fixedly connected to the outer side of the baffle plate 501. A spring 507 is fixedly connected between the fixed end of the telescopic plate 504 and the machine body 100. Two sets of connecting rods 505 are fixedly connected to the outside of the extrusion rod 107. A fixing rod 506 is fixedly connected between the two sets of connecting rods 505 and above the telescopic plate 504. By setting the fixing rod 506, the fixing rod 506 can press the telescopic plate 504 down. The telescopic plate 504 and the fixing rod 506 fit together. The end of the opening 502 near the baffle plate 501 is set as an inclined surface.

[0026] In practical use, when the extrusion rod 107 moves forward, it drives the connecting rod 505, which in turn drives the fixed rod 506 to move towards the baffle plate 501. This allows the fixed rod 506 to press down the telescopic plate 504, which in turn drives the baffle plate 501 to move downwards, thus blocking the spattering welding slag. When the extrusion rod 107 returns to its original position, the connecting rod 505 drives the fixed rod 506 to gradually move away from the baffle plate 501, thus ending the fixed rod 506's obstruction of the telescopic plate 504. The telescopic plate 504 can then return to its original position due to the elastic force of the spring 507, which in turn drives the baffle plate 501 back to its original position.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
