Abstract
Description
Technical Field
[0001] This invention belongs to the field of welding positioning technology, and particularly relates to a welding positioning device for steel reinforcement components used in building construction, and a working method of the welding positioning device for steel reinforcement components used in building construction. Background Technology
[0002] Reinforcing steel bars are widely used materials in construction engineering. Most of their application is as a supporting framework. Due to the limited length of reinforcing steel bars, they need to be welded to achieve the required length. During welding, the connection between two reinforcing steel bars should prioritize coaxial alignment to ensure smooth force transmission when the steel bars are under stress and to avoid additional bending moments caused by eccentricity, which could affect structural safety. Therefore, a positioning device is used to fix the reinforcing steel bars coaxially before welding.
[0003] Since the positioning device occupies the welding position, removing or replacing the positioning device can cause the steel bar to tilt due to its own weight, resulting in potential stress problems for steel bars with different axes, thereby reducing the load-bearing capacity of the steel bar. Summary of the Invention
[0004] To address the problems in the prior art, the present invention proposes the following technical solution: A welding positioning device for reinforcing steel bars used in building construction, comprising: The fixing cylinder has two cylinders, which are sleeved on the ends of two steel bars. The fixing cylinder is provided with a clamping component for clamping and fixing the steel bars. A support module is used to connect two fixed cylinders. The support module includes a first support rod and a second support rod. The two ends of the first support rod and the second support rod are respectively rotatably sleeved on the two fixed cylinders, and the second support rod is located outside the first support rod. After placing the steel bars to be welded, the clamping components inside the two fixed cylinders align the two steel bars coaxially and clamp and fix them. The first support rod and the second support rod are placed on both sides to maintain the connection between them. Welding equipment is used to weld the joint of the steel bars. The first support rod or the second support rod is pushed away from the position to be welded to avoid obstruction.
[0005] As a preferred embodiment of the above technical solution, the clamping assembly includes a lead screw and a worm gear reducer. The lead screw has reverse-oriented threads at both ends, and fixed clamping plates are fitted onto the threaded surfaces at both ends of the lead screw. The output end of the worm gear reducer is fixedly connected to the lead screw. The dual input ends of the worm gear reducer are respectively provided with a clockwise rotating gear and a counterclockwise rotating gear. When the clockwise gear rotates clockwise, the lead screw rotates clockwise, causing the two fixed clamping plates to move towards each other to clamp the end of the steel bar. When the counterclockwise gear rotates counterclockwise, the lead screw rotates counterclockwise, causing the two fixed clamping plates to move in the opposite direction and reset.
[0006] As a preferred embodiment of the above technical solution, it further includes two linkage components, each located within a fixed cylinder. Each linkage component includes a clockwise gear ring and a counter-clockwise gear ring. One end of the clockwise gear ring meshes with a clockwise gear, and the other end of the clockwise gear ring is connected to a first one-way member between itself and a first support rod. The clockwise gear ring and the clockwise gear rotate through a first limiting groove. One end of the counter-clockwise gear ring meshes with a counter-clockwise gear, and the other end of the counter-clockwise gear ring is connected to a second support rod. The first support rod, through the first one-way member, rotates the clockwise gear ring only clockwise, and the second support rod, through the second one-way member, rotates the counter-clockwise gear ring only counter-clockwise. Normally rotating first and second support rods respectively perform the clamping and releasing actions of the clamping components, while reverse rotation of the first and second support rods completes the welding avoidance work.
[0007] As a preferred embodiment of the above technical solution, the first unidirectional component includes a plurality of circumferentially arranged toothed blocks, and the surface of the toothed ring is provided with a plurality of corresponding first limiting grooves.
[0008] As a preferred embodiment of the above technical solution, the second unidirectional component includes a plurality of circumferentially arranged reverse tooth blocks, and the surface of the reverse tooth ring is provided with a plurality of corresponding second limiting grooves.
[0009] As a preferred embodiment of the above technical solution, both the first support rod and the second support rod are provided with fixing components. The fixing components include a pressing block and two pushing blocks. The ends of the pressing block and the pushing block are provided with elastic blocks. Both ends of the pushing block are connected to connecting rods. The ends of the connecting rods are provided with insertion blocks. The surface of the fixing cylinder is provided with several corresponding insertion slots.
[0010] As a preferred embodiment of the above technical solution, the two sides of the extrusion block are sloped, and the two pushing blocks are matched with the slopes.
[0011] As a preferred embodiment of the above technical solution, the pushing blocks in the first support rod and the pushing blocks in the second support rod are arranged in opposite directions, and the insertion blocks in the first support rod and the insertion blocks in the second support rod are also arranged in opposite directions.
[0012] A method for operating a welding positioning device for reinforcing steel bars used in building construction includes the following steps: S1. Place the reinforcing steel piece; hold the first or second support rod and attach one of the fixing cylinders to the end of the fixed reinforcing steel piece, then insert the end of the reinforcing steel piece to be welded through the other fixing cylinder; S2. Fixing the reinforcing bars: After the ends of the two reinforcing bars come into contact, use the clamping assembly to clamp and fix the reinforcing bars and align them coaxially. The first and second support rods on both sides maintain the connection between the two fixing cylinders to support the reinforcing bars. S3. Welding treatment; Use welding equipment to weld the joints of the reinforcing steel parts, and push the first or second support rod away from the position to be welded to avoid it; S4. Remove the positioning device; after welding is completed, reset the clamping assembly, move the device to the other end of the steel bar and remove it for the next welding process.
[0013] The beneficial effects of this invention are as follows: 1. The first and second support rods connecting the two fixed cylinders can stably support the steel bars. During welding, the positions of the first and second support rods can be rotated away from the welding position, eliminating the need to disassemble and reinstall the device. This maintains stable support for the steel bars, prevents them from tilting and becoming misaligned, and ensures that there are no potential stress hazards that could reduce the load-bearing capacity of the steel bars. 2. By cooperating with the unidirectional components of the first and second support rods respectively, a mechanical logic of "unidirectional drive - bidirectional action" is constructed. When the first support rod rotates clockwise, it drives the clockwise gear to rotate. The clockwise gear drives the lead screw to rotate through the worm gear reducer, causing the fixed clamping plates to move in opposite directions to clamp the steel bar. Reverse rotation does not affect the clamping state and is only used for avoidance. When the second support rod rotates counterclockwise, it drives the reverse gear to rotate. The reverse gear drives the lead screw to rotate through the worm gear reducer, causing the fixed clamping plates to move in the opposite direction to release the steel bar. Reverse rotation is also only used for avoidance. The "clamping / releasing" and "avoidance" functions are realized through the same component, and they do not interfere with each other during operation, making it more convenient to use. 3. The clamping assembly adopts a bidirectional reverse threaded screw fixing clamp design. The rotation of the screw drives the two clamps to move in opposite directions, which can adapt to steel bars of different diameters. There is no need to replace the special clamps, which is highly versatile and reduces construction costs. Attached Figure Description

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.
[0017] Figures 1-5 A welding positioning device for reinforcing steel bars used in building construction includes: The fixing cylinder 10 is provided in two parts, and the two fixing cylinders 10 are sleeved on the ends of two steel bars. The fixing cylinder 10 is provided with a clamping component 40 for clamping and fixing the steel bars. A support module is used to connect two fixed cylinders 10. The support module includes a first support rod 20 and a second support rod 30. The two ends of the first support rod 20 and the second support rod 30 are respectively rotatably sleeved on the two fixed cylinders 10, and the second support rod 30 is located outside the first support rod 20. After placing the steel bars to be welded, the clamping components 40 inside the two fixing cylinders 10 align the two steel bars coaxially and clamp and fix them. The first support rod 20 and the second support rod 30 are placed on both sides to maintain the connection between them. Welding equipment is used to weld the joint of the steel bars. The first support rod 20 or the second support rod 30 is pushed away from the position to be welded to avoid obstruction.
[0018] The first support rod 20 and the second support rod 30 connecting the two fixed cylinders 10 can stably support the steel reinforcement. During welding, the first support rod 20 and the second support rod 30 can be rotated away from the welding position without disassembling and reinstalling the device. This maintains stable support for the steel reinforcement, prevents the steel reinforcement from tilting and becoming misaligned, and ensures that there are no potential stress hazards that could reduce the load-bearing capacity of the steel reinforcement.
[0019] A method for operating a welding positioning device for reinforcing steel bars used in building construction includes the following steps: S1. Place the reinforcing bar; hold the first support rod 20 or the second support rod 30 and attach one of the fixing cylinders 10 to the end of the fixed reinforcing bar, and then insert the end of the reinforcing bar to be welded through the other fixing cylinder 10. S2. Fixing the reinforcing bars; After the ends of the two reinforcing bars come into contact, the clamping assembly 40 is used to clamp and fix the reinforcing bars and align them coaxially. The first support rod 20 and the second support rod 30 on both sides maintain the connection between the two fixing cylinders 10 and support the reinforcing bars. S3. Welding treatment; Use welding equipment to weld the joint of the steel reinforcement components, and push the first support rod 20 or the second support rod 30 away from the position to be welded to avoid it; S4. Remove the positioning device; after welding is completed, reset the clamping assembly 40, move the device to the other end of the steel bar and remove it for the next welding process.
[0020] Figures 2-4 In this assembly, the clamping component 40 includes a lead screw 41 and a worm gear reducer 42. The lead screw 41 has reverse-oriented threads at both ends, and fixed clamping plates 43 are sleeved on the threaded surfaces at both ends of the lead screw 41. The output end of the worm gear reducer 42 is fixedly connected to the lead screw 41. The worm gear reducer 42 has a clockwise rotating clock gear 44 and a counterclockwise rotating counter gear 45 respectively at its dual input ends. When the clock gear 44 rotates clockwise, the lead screw 41 rotates clockwise, causing the two fixed clamping plates 43 to move towards each other to clamp the end of the steel bar. When the counter gear 45 rotates counterclockwise, the lead screw 41 rotates counterclockwise, causing the two fixed clamping plates 43 to move in the opposite direction and reset.
[0021] The clamping assembly 40 adopts a design with a bidirectional reverse threaded screw 41 to fix the clamping pieces 43. The two clamping pieces move in opposite directions or towards each other by rotating the screw 41, which can adapt to steel bars of different diameters. There is no need to replace the special clamps, which is highly versatile and reduces construction costs.
[0022] Figures 2-4The system also includes two linkage components 50, each located within a fixed cylinder 10. Each linkage component 50 includes a clockwise gear ring 51 and a counterclockwise gear ring 52. One end of the clockwise gear ring 51 meshes with a clockwise gear 44, and the other end of the clockwise gear ring 51 is connected to a first one-way member between itself and a first support rod 20. The clockwise gear ring 51 and the clockwise gear 44 are rotated via a first limiting groove 532. One end of the counterclockwise gear ring 52 meshes with a counterclockwise gear 45, and the other end of the counterclockwise gear ring 52 is connected to a second one-way member between itself and a second support rod 30. The first support rod 20 rotates the clockwise gear ring 51 only when rotating clockwise via the first one-way member, and the second support rod 30 rotates the counterclockwise gear ring 52 only when rotating counterclockwise via the second one-way member. The normally rotating first support rod 20 and the second support rod 30 respectively perform the clamping and releasing actions of the clamping component 40, while the reverse rotation of the first support rod 20 and the second support rod 30 completes the welding avoidance work.
[0023] The first unidirectional component includes a plurality of circumferentially arranged toothed blocks 531, and the surface of the toothed ring 51 is provided with a plurality of corresponding first limiting grooves 532.
[0024] The second unidirectional component includes a plurality of circumferentially arranged reverse tooth blocks 541, and the surface of the reverse tooth ring 52 is provided with a plurality of corresponding second limiting grooves 542.
[0025] By cooperating with the unidirectional components of the first and second support rods 30, respectively, the clockwise gear ring 51 and counterclockwise gear ring 52 construct a mechanical logic of "unidirectional drive - bidirectional action". When the first support rod 20 rotates clockwise only, it drives the clockwise gear ring 51 to rotate. The clockwise gear 44 drives the lead screw 41 to rotate through the worm gear reducer 42, causing the fixed clamping plate 43 to move in opposite directions to clamp the steel bar. When rotating in the opposite direction, it does not affect the clamping state and is only used for avoidance. When the second support rod 30 rotates counterclockwise only, it drives the counterclockwise gear ring 52 to rotate. The counterclockwise gear 45 drives the lead screw 41 to rotate through the worm gear reducer 42, causing the fixed clamping plate 43 to move in the opposite direction to release the steel bar. When rotating in the opposite direction, it is also only used for avoidance. The "clamping / release" and "avoidance" functions are realized through the same component, and they do not interfere with each other during operation, making it more convenient to use.
[0026] Figure 2 and Figure 5 In the middle, the first support rod 20 and the second support rod 30 are both provided with fixing members 60. The fixing member 60 includes a pressing block 61 and two pushing blocks 62. The ends of the pressing block 61 and the pushing block 62 are provided with elastic blocks 63. The two ends of the pushing block 62 are connected to connecting rods 64. The ends of the connecting rods 64 are provided with insertion blocks 65. The surface of the fixing cylinder 10 is provided with several corresponding insertion slots 66.
[0027] The extrusion block 61 has sloping surfaces on both sides, and the two push blocks 62 are matched with its sloping surfaces.
[0028] The pushing block 62 in the first support rod 20 and the pushing block 62 in the second support rod 30 are arranged in opposite directions, and the insertion block 65 in the first support rod 20 and the insertion block 65 in the second support rod 30 are arranged in opposite directions.
[0029] Pressing the squeezing block 61 pushes the pushing block 62 to move, and the connecting rod 64 then drives the plug block 65 to leave the plug slot 66 position. The fixing member 60 then disconnects the fixing between the first support rod 20 or the second support rod 30 and the two fixing cylinders 10, thus completing the effect of holding and pressing to adjust the position of a single support module.
[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
