Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to an I-beam welding tool for green building construction. Background Art

[0002] I-beams, also known as steel beams, are long strips of steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. I-beams are mainly used in building structures, curtain wall projects, mechanical equipment, and vehicle manufacturing. Most I-beams are used in engineering construction. In engineering construction, there is a need to install the I-beam to be installed between two I-beams that have been fixed on the ceiling or at a high place. Since the models of I-beams are the same, it is necessary to manually cut off the flanges of the I-beams to be installed on site, exposing part of the web, so that the web of the cut I-beam can enter between the two flanges of the two installed I-beams, and then weld them. In the prior art, after the I-beam wing plate to be installed is cut off, there will be surface defects in the cutting area, which makes it impossible to embed the web into the two wing plates, and grinding and trimming are required. Most of them are done manually. After the manual grinding is completed, splicing is performed, and then it is necessary to determine whether the connection is flush. When the connection is not flush, the I-beam wing plate needs to be grinded a second time and spliced ​​again. This process requires the I-beam to be installed to be continuously transferred back and forth between the installation location such as the ceiling and the ground processing area, resulting in the installation work taking too long.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0024] See also Figures 1 to 7 The present invention provides an I-beam welding tool for green building construction, comprising a frame 1 that moves on the I-beam A26, the frame 1 comprising a vertically arranged column 2, a support frame 3 fixedly arranged at the lower end of the column 2, a walking wheel 4 for moving on the I-beam is arranged on the support frame 3, and a set of fixing mechanisms 5 for fixing the frame 1 on the I-beam are respectively fixedly arranged on both sides of the support frame 3; A positioning mechanism 6 is also provided on the frame 1, and a detachable connecting I-beam B27 is provided on the positioning mechanism 6.

[0025] The user moves the mobile frame 1 along the I-beam A26 until the target welding position, fixes the frame 1 on the I-beam A26 through the fixing mechanisms 5 on both sides of the support frame 3, and connects the I-beam B27 with the positioning mechanism 6. After the wing plate of the I-beam B27 is cut, there will be surface defects in the cutting area, which makes it impossible to embed the web into the two wing plates, and grinding and trimming are required. Most of them are done by manual grinding. After the manual grinding is completed, splicing is performed, and then it is necessary to determine whether the connection is flush. When the connection is not flush, the I-beam wing plate needs to be polished again and spliced ​​again. The device only needs to adjust the position of the positioning mechanism 6 to achieve the adjustment of the state of the I-beam B27; The device realizes in-situ trimming in the air through dynamic adjustment of the positioning mechanism 6, the number of hoisting times is reduced to one, the work efficiency is improved, and the welding time of the I-beam is shortened.

[0026] The positioning mechanism 6 includes two active rods 7 arranged in parallel, the upper end of the active rod 7 is rotatably connected to the upper end of the frame 1, and the lower ends of the two active rods 7 are rotatably connected through a lower connecting rod; A driven rod 8 is rotatably arranged at the lower end of each active rod 7, and the movable end of the driven rod 8 is rotatably connected through an adapter frame 9, on which a connecting unit 10 is fixedly arranged, and an I-beam B27 is detachably arranged on the connecting unit 10; An adjusting nut 11 is rotatably provided at the middle of an active rod 7 away from one side of the frame 1, the adjusting nut 11 is internally threadedly connected to a screw rod 12, and the lower end of the screw rod 12 is rotatably connected to the frame 1; The user fixes the frame 1 on the I-beam A26, connects the I-beam B27 to the positioning mechanism 6, and a handle is fixedly provided on the upper end of the screw rod 12. The user can rotate the screw rod 12 by turning the handle, thereby driving the adjustment nut 11 to move, so that the active rod 7 rotates around the upper end of the frame 1; Since the active rod 7, the lower connecting rod and the driven rod 8 form a parallel four-bar linkage, the adapter frame 9 remains in a horizontal state, and the position of the I-beam B27 is adjusted to make the I-beam B27 away from the I-beam A26, so that the user can grind and trim the I-beam B27. After the grinding and trimming is completed, the screw rod 12 is rotated in the opposite direction to insert the I-beam B27 into the upper and lower flanges of the I-beam A26. After confirming that the alignment is correct, temporary spot welding is performed to ensure that the I-beam is stably connected. Finally, the I-beam is fully welded.

[0027] A large gear 13 is fixedly provided at the lower end of an active rod 7 away from the frame 1, and a small gear 14 is rotatably provided at the lower end of the other active rod 7. The small gear 14 is fixedly connected to the driven rod 8, and the large gear 13 and the small gear 14 are meshed with each other.

[0028] The number of teeth of the large gear 13 is twice the number of teeth of the small gear 14 .

[0029] Since the gear transmission ratio is 2:1, the rotation angle of the driven rod 8 is twice that of the active rod 7. This transmission relationship ensures that the I-beam B27 maintains parallel movement, so that the horizontal height of the I-beam B27 and the I-beam A26 are always consistent, making it easier for users to observe the docking status.

[0030] The connecting unit 10 includes a cross bar 15 fixedly mounted on the adapter frame 9. Two ends of the cross bar 15 are respectively provided with slots. A clamping block 16 is slidably mounted in each slot. The two clamping blocks 16 are arranged opposite to each other. An adjusting screw 17 is rotatably disposed in the cross bar 15 . Threads are disposed at both ends of the adjusting screw 17 . The threads at both ends of the adjusting screw 17 are threadedly connected to one of the clamping blocks 16 .

[0031] A knob is fixedly disposed at each end of each adjusting screw 17; Place the upper flange of the I-beam B27 between two clamping blocks 16 arranged opposite to each other, rotate the adjusting screw 17, drive the two clamping blocks 16 to move synchronously toward each other through the bidirectional thread, and continue to rotate the adjusting screw 17 until the clamping block 16 is in close contact with the upper flange of the I-beam. The thread transmission provides a stable clamping force to prevent position deviation during welding. A single long screw controls the double clamping blocks 16, and the clamping and releasing operations are simple and fast, which can be adapted to I-beams of different specifications; Moreover, the I-beam B27 can be always located in the middle of the adapter frame 9, ensuring balanced force during clamping, avoiding the phenomenon of sinking due to the shift of the center of gravity, and improving the safety of high-altitude operations.

[0032] The fixing mechanism 5 includes a locking screw 18 fixedly arranged on the frame 1, and a clamping arm 19 is rotatably arranged at one end of the locking screw 18 close to the column 2; A sleeve 20 is sleeved on the locking screw 18 , a locking hook 21 is fixedly arranged on the sleeve 20 , the locking hook 21 is clamped with the upper flange of the I-beam A26 , a movable nut 22 is rotatably arranged in the middle of the sleeve 20 , and the movable nut 22 is threadedly connected with the locking screw 18 .

[0033] Move the frame 1 to the predetermined position of the I-beam A26, ensure that the travel wheel 4 is in contact with the flange of the I-beam, rotate the moving nut 22, drive the sleeve 20 to move toward the column 2, and make the locking hook 21 initially engage with the upper flange of the I-beam; A slot is provided along the axis of the locking screw 18 , and a boss is provided on the sleeve 20 , and the boss slides in the slot.

[0034] The boss on the sleeve 20 moves linearly along the slot of the locking screw 18 to prevent the sleeve 20 from rotating during use.

[0035] The end of the locking screw 18 away from the clamp arm 19 is rotatably provided with a support rod 23, the support rod 23 is "L" shaped, the shorter end of the support rod 23 is rotatably connected to the locking screw 18, and the other end of the support rod 23 is bent upward and rotatably provided with a control handle 24, and the control handle 24 is rotatably connected to the upper end of the clamp arm 19; The operator presses down the control handle 24, and under the action of the support rod 23, the clamp arm 19 is further tightened. When the rotation axis of the support rod 23 and the locking screw 18, the rotation axis of the support rod 23 and the control handle 24, and the rotation axis of the control handle 24 and the clamp arm 19 are in a straight line, the support rod 23, the control handle 24 and the clamp arm 19 are in a dead point position, and the fixing mechanism 5 can firmly clamp the I-beam A26; A pry bar 25 is rotatably disposed in the middle of the handle, and the pry bar 25 abuts against the support rod 23 .

[0036] When the device needs to be unlocked, the movable end of the pry bar 25 is pressed down, and the pry bar 25 pries the control handle 24 to break the dead point state, release the clamp arm 19, and reversely rotate the movable nut 22 to move the sleeve 20 outward, and the locking hook 21 is separated from the I-beam flange to complete the unlocking.

[0037] When the present invention is used, the user moves the frame 1 along the I-beam A26 until the target welding position, fixes the frame 1 on the I-beam A26 through the fixing mechanisms 5 on both sides of the support frame 3, and connects the I-beam B27 with the positioning mechanism 6. After the wing plate of the I-beam B27 is cut, there will be surface defects in the cutting area, which makes it impossible to embed the web into the two wing plates, and grinding and trimming are required. Most of them adopt manual grinding. After the manual grinding is completed, splicing is performed, and then it is necessary to determine whether the connection is flush. When the connection is not flush, the I-beam wing plate needs to be polished again and spliced ​​again. The device only needs to adjust the position of the positioning mechanism 6 to achieve the adjustment of the state of the I-beam B27; The device realizes in-situ trimming in the air through dynamic adjustment of the positioning mechanism 6, the number of hoisting times is reduced to one, the work efficiency is improved, and the welding time of the I-beam is shortened.
