Description

Technical Field

[0001] This invention relates to the field of reinforcement technology for existing steel structures, specifically to a reinforcement and renovation device based on existing steel structures. Background Technology

[0002] In the fields of architecture, bridges, and industrial plants, many existing steel column structures require reinforcement and renovation to ensure structural safety and service life due to factors such as long-term service, load changes, environmental erosion, or upgrades in design standards. Welding reinforcement is one of the most commonly used core processes in the renovation of existing steel column structures. It improves the load-bearing capacity and stability of steel columns by welding reinforcing components (such as stiffening plates and sleeves) to weak points in the steel columns.

[0003] Current welding equipment used for reinforcing existing steel columns generally suffers from technical defects such as incomplete operational coverage and poor adaptability to working conditions, making it difficult to meet the reinforcement needs in complex scenarios. Specifically, traditional welding equipment is mostly designed with fixed positions, which can only perform welding operations on local areas of the steel column. When welding is required at different circumferential positions or different vertical heights of the steel column, the installation position of the equipment must be repeatedly adjusted manually or the welding equipment must be moved. This is not only cumbersome and labor-intensive, but also prone to problems such as misalignment of welded joints and unstable welding quality due to deviations in machine position adjustment.

[0004] Based on this, the present invention designs a reinforcement and renovation device based on existing steel structures to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a reinforcement and renovation device based on existing steel structures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reinforcement and renovation device based on an existing steel structure, including a welding machine capable of welding the steel structure, and a locking drive assembly capable of moving up and down on the steel structure; the locking drive assembly is further provided with two sets of rotary transmission assemblies for driving the welding machine to rotate circumferentially around the outer periphery of the steel structure. The engagement drive assembly includes an engagement plate one and an engagement plate two that can move up and down on the steel structure. The two engagement plates one and two are detachably engaged through a matching engagement structure to form a radial clamping limit on the steel structure. Both the first and second locking plates have arc-shaped blocks fixedly connected to their grooves. The arc-shaped blocks are equipped with tracks. After the first and second locking plates form a radial clamping limit on the steel structure, the tracks can drive the first and second locking plates to move up and down on the steel structure.

[0007] As a further embodiment of the present invention, the rotary transmission assembly includes two sliding plates respectively disposed on a first locking plate and a second locking plate, which enable the welding machine to rotate circumferentially around the outer periphery of the steel structure. Each sliding plate is provided with a fixed box, and the welding machine is disposed on the fixed box. Each of the sliding plates is fixedly connected to a bidirectional drive motor; the drive motor is provided with a first output terminal and a second output terminal. The second output end of the drive motor passes through the sliding plate and extends to its lower surface where a drive gear is fixedly connected. Both the first and second locking plates are provided with toothed grooves that can mesh with the drive gear.

[0008] As a further embodiment of the present invention, the rotary transmission assembly further includes a slide groove that allows the welding machine to slide vertically in the fixed box after the locking plate 1 and the locking plate 2 are positioned. The fixed end of the welding machine extends through and into the interior of the fixed box and is slidably connected to the slide groove. A limit plate is fixedly connected to the fixed end of the welding machine. A reset spring for resetting is fixedly connected to the limit plate and the inner wall of the fixed box. A traction rope is fixedly connected to the lower surface of the limit plate. A winding wheel for driving the welding machine to descend is fixedly connected to the lower end of the traction rope. The winding wheel is fixedly connected to the first output end of the drive motor.

[0009] As a further embodiment of the present invention, a locking block is slidably connected to the two locking ends of the locking plate 1 on the second locking plate, and the locking block is elastically connected to the second locking plate by a pressure spring. The locking plate is provided with a locking groove that matches the locking block.

[0010] As a further aspect of the present invention, the tooth groove is a continuous annular tooth groove.

[0011] As a further embodiment of the present invention, the outer peripheral wall of the winding reel is provided with a spiral rope groove, and the traction rope is wound in the spiral rope groove. The traction rope is a galvanized steel wire rope, and its diameter is adapted to the groove width of the spiral rope groove.

[0012] As a further aspect of the present invention, the inner arc surface of the arc-shaped block is provided with an anti-slip and wear-resistant pad layer.

[0013] As a further embodiment of the present invention, the track is a rubber track, the inner side of the track is provided with transmission teeth that mesh with the drive wheel, and the outer side of the track is provided with anti-slip patterns to increase the friction with the surface of the steel structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The sliding plate drives the fixed box mounted on it to move synchronously, thereby pulling the welding machine mounted on the fixed box to rotate circumferentially along the outer perimeter of the steel column structure, achieving welding operations covering different circumferential directions of the steel structure. Through the cooperation of the sliding groove and the limiting plate, precise vertical guidance and sliding of the welding machine are achieved, eliminating the need for repeated adjustments to the installation position of the device or the relocation of the welding equipment.

[0015] 2. The combination of the height adjustment structure and the circumferential rotation function of the rotary transmission component enables the welding machine to achieve multi-dimensional movement of circumferential rotation and vertical lifting along the steel structure, which can fully cover the welding operation area and adapt to welding needs under different working conditions, such as downward-sloping welds, significantly improving the adaptability of the device and the comprehensiveness of welding operations.

[0018] Please see Figures 1-7 The present invention provides a technical solution: a reinforcement and renovation device based on an existing steel structure, including a welding machine 1 capable of welding the steel structure, and a locking drive assembly capable of moving up and down on the steel structure; the locking drive assembly is further provided with two sets of rotary transmission assemblies for driving the welding machine 1 to rotate circumferentially around the outer periphery of the steel structure. The engaging drive assembly includes an engaging plate 2 and an engaging plate 3 that can move up and down on the steel structure. The two engaging plates 2 and 3 are detachably engaged through a matching engaging structure to form a radial clamping limit on the steel structure. Arc-shaped blocks 4 are fixedly connected to the grooves of the first clamping plate 2 and the second clamping plate 3. Tracks 5 are provided on the arc-shaped blocks 4. After the first clamping plate 2 and the second clamping plate 3 form a radial clamping limit on the steel structure, the tracks 5 can drive the first clamping plate 2 and the second clamping plate 3 to move up and down on the steel structure.

[0019] When performing reinforcement and welding work on existing steel column structures, the first clamping plate 2 and the second clamping plate 3 are first attached to the outer perimeter of the steel structure. The two are detachably clamped through their matching clamping structure, so that the first clamping plate 2 and the second clamping plate 3 form a clamping space that matches the outline of the steel structure, thereby forming a stable radial clamping limit on the steel structure. After the clamping drive assembly completes the clamping and positioning, the electric track 5 configured on the arc block 4 is started. During the operation of the electric track 5, effective friction is generated with the surface of the steel structure, thereby driving the first clamping plate 2 and the second clamping plate 3 to move along the extension direction of the steel structure to the designated position. Then, the two sets of rotary transmission components mounted on the clamping drive assembly move synchronously, driving the welding machine 1 to rotate circumferentially around the outer perimeter of the steel structure, so that the welding machine 1 can complete continuous welding operations at different height positions and circumferential positions of the steel structure.

[0020] The detachable clamping structure of clamping plate 2 and clamping plate 3 enables rapid clamping and positioning of steel column structures of different specifications. It is highly adaptable and easy to operate, effectively reducing the installation difficulty and preparation time of the device on the steel structure surface. With the help of the crawler 5 driving the clamping drive assembly to move up and down along the steel structure, and in conjunction with the rotary transmission assembly driving the circumferential rotation of the welding machine 1, the welding machine 1 can achieve full-dimensional operation coverage on the steel structure surface. There is no need for repeated manual adjustment of the welding position, which significantly improves the automation level and work efficiency of the reinforcement and renovation welding operation. At the same time, the radial clamping and limiting design of the clamping drive assembly on the steel structure ensures the stability of the relative position between the device and the steel structure during the welding process, avoiding welding quality defects caused by device offset, which is conducive to improving the construction quality and reliability of steel structure reinforcement and renovation.

[0021] As a further embodiment of the present invention, the rotary transmission assembly includes two sliding plates 6 respectively disposed on the first locking plate 2 and the second locking plate 3, which are capable of the welding machine 1 rotating around the outer periphery of the steel structure. Each sliding plate 6 is provided with a fixed box 7, and the welding machine 1 is disposed on the fixed box 7. Each of the sliding plates 6 is fixedly connected to a bidirectional drive motor 8; the drive motor 8 is provided with a first output terminal 9 and a second output terminal 10. The second output end 10 of the drive motor 8 passes through the sliding plate 6 and extends to its lower surface where a drive gear 11 is fixedly connected. Both the first locking plate 2 and the second locking plate 3 are provided with tooth grooves 12 that can mesh with the drive gear 11.

[0022] When the welding machine 1 performs circumferential welding around the outer perimeter of the steel structure, the bidirectional drive motor 8 fixedly connected to the sliding plate 6 is started. The second output end 9 of the bidirectional drive motor 8 drives the drive gear 11 fixedly connected to it to rotate synchronously. Since the two drive gears 11 mesh with the toothed grooves 12 opened on the first and second clamping plates 2 and 3, the rotational motion of the drive gears 11 is converted into the circumferential movement of the sliding plate 6 along the toothed grooves 12 through gear meshing transmission. The sliding plate 6 drives the fixed box 7 set on it to move synchronously, thereby pulling the welding machine 1 installed on the fixed box 7 to rotate circumferentially around the outer perimeter of the steel column structure, so as to achieve welding operation coverage of different circumferential directions of the steel structure.

[0023] It can precisely control the circumferential displacement trajectory of welding machine 1 to ensure the forming quality of the welded joint; the two sets of rotary transmission components are respectively mounted on clamping plate 1 2 and clamping plate 2 3, which can realize synchronous or asynchronous operation of dual welding machines 1, and greatly improve the welding efficiency of steel structure reinforcement and renovation.

[0024] As a further embodiment of the present invention, the rotary transmission assembly further includes a slide groove 20 that allows the welding machine 1 to slide vertically in the fixed box 7 after the locking plate 1 2 and the locking plate 2 3 are positioned. The fixed end of the welding machine 1 extends through and into the interior of the fixed box 7 and is slidably connected to the slide groove 20. A limit plate 13 is fixedly connected to the fixed end of the welding machine 1. A reset spring 14 for resetting is fixedly connected to the limit plate 13 and the inner wall of the fixed box 7. A traction rope 15 is fixedly connected to the lower surface of the limit plate 13. A winding wheel 16 for driving the welding machine 1 to descend is fixedly connected to the lower end of the traction rope 15. The winding wheel 16 is fixedly connected to the first output end 9 of the drive motor 8.

[0025] After the locking plates 1 and 2 complete the limiting and fixing of the steel structure, when the weld is oblique and the welding operation requires adjusting the height of the welding machine 1, the bidirectional drive motor 8 starts and drives the winding wheel 16 to rotate through the first output end 9. During the rotation of the winding wheel 16, a winding force is generated on the traction rope 15. The traction rope 15 pulls the limiting plate 13 fixedly connected to it, so that the limiting plate 13 drives the fixed end of the welding machine 1 to slide down along the slide groove 20 in the fixed box 7, thereby realizing the height adjustment of the welding machine 1. At the same time, the drive gear 11 drives the sliding plate 6 to drive the fixed box 7 set on it to move synchronously, so that the welding machine 1 installed on the fixed box 7 makes circumferential rotation along the outer periphery of the steel structure, realizing the welding operation of the oblique weld of the steel column structure; so as to adapt to the welding requirements of different weld positions.

[0026] When the welding machine 1 needs to be reset and raised, the drive motor 8 controls the first output end 9 to rotate in the opposite direction, and the winding wheel 16 releases the traction rope 15. At this time, the reset spring 14, which is fixedly connected to the limit plate 13 and the inner wall of the fixed box 7, pushes the limit plate 13 to move upward by its own elastic reset force, thereby driving the welding machine 1 to rise back to the initial position along the slide 20 and complete the height reset.

[0027] The height adjustment structure, combined with the circumferential rotation function of the rotary transmission component, enables the welding machine 1 to achieve multi-dimensional motion of circumferential rotation and vertical lifting along the steel structure. This allows it to fully cover the welding operation area, adapt to welding needs under different working conditions, and significantly improve the adaptability of the device and the comprehensiveness of the welding operation.

[0028] As a further embodiment of the present invention, a locking block 17 is slidably connected to the two locking ends of the locking plate 2 on the second locking plate 3, and the locking block 17 is elastically connected to the second locking plate 3 by a pressure spring 18. The locking plate 2 is provided with a locking groove 19 that is adapted to the locking block 17.

[0029] like Figure 7 As shown, when assembling the first clamping plate 2 and the second clamping plate 3 to clamp the steel structure, the clamping block 17 is pulled to overcome the elastic force of the pressure spring 18 and move to the outside of the second clamping plate 3. Then the clamping block 17 enters the clamping groove 19, and the clamping block 17 is released so that the clamping block 17 is locked in the clamping groove 19.

[0030] The elastic fit design of the pressure spring 18 and the locking block 17 enables quick assembly and disassembly of the locking plate 12 and the locking plate 23 without the need for additional tools, which greatly reduces the difficulty of installation and disassembly of the device on the steel structure and saves preparation and finishing time.

[0031] As a further embodiment of the present invention, the tooth groove 12 is a continuous annular tooth groove.

[0032] As a further embodiment of the present invention, the outer peripheral wall of the winding reel 16 is provided with a spiral rope groove, and the traction rope 15 is wound in the spiral rope groove. The traction rope 15 is a galvanized steel wire rope, and its diameter is adapted to the groove width of the spiral rope groove.

[0033] As a further embodiment of the present invention, the inner arc surface of the arc block 4 is provided with an anti-slip and wear-resistant pad layer.

[0034] As a further embodiment of the present invention, the track 5 is a rubber track, the inner side of the track 5 is provided with transmission teeth that mesh with the drive wheel, and the outer side of the track 5 is provided with anti-slip patterns to increase the friction with the surface of the steel structure.
