Description

Technical Field

[0001] This invention relates to the field of welding technology for temporary fixing of cantilever continuous beams, and in particular to a welding device for temporary fixing of cantilever continuous beams. Background Technology

[0002] In the field of bridge engineering, cantilever continuous beams are widely used in scenarios such as river crossings, road crossings, and urban viaducts due to their advantages such as large span capacity and reasonable structural stress. The core construction process is the cantilever casting method, which involves casting the beam segment by segment using a hanging basket to form a continuous structure. However, during cantilever construction, the connection between the beam and the pier needs to be secured by temporary measures to ensure stability and prevent structural instability caused by unbalanced bending moments or vertical forces.

[0003] Existing welding devices for temporary fixation of cantilever continuous beams have several drawbacks. First, they cannot quickly weld around the joints of reinforcing bars, often requiring secondary movement and repositioning of the welding equipment, which reduces work efficiency. Second, there is no stable welding environment between the two reinforcing bars, leading to instability and misalignment during welding. Third, welding is impossible when the distance between the two reinforcing bars is large. Therefore, this invention is proposed to solve the above problems. Summary of the Invention

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Reference Figures 1 to 7This invention provides a welding device for temporary fixing of cantilever continuous beams. It enables rapid welding around reinforcing bars to achieve temporary fixing. Before welding, it can automatically fix two reinforcing bars to be temporarily welded and extend the reinforcing bars to complete the subsequent temporary welding fixation. The device includes a rotating assembly 100, comprising a welding assembly 200 and a data acquisition device 300 fixed to the inner wall of the rotating assembly 100; a docking assembly 400 connected to the top of the rotating assembly 100, the top of which has connecting lugs for connection to a mobile device or suspension device, allowing the device to be moved to the reinforcing bar to be welded; four fixing assemblies 500 connected to the bottom of the docking assembly 400; and four driven assemblies 600 connected to the left side inside the welding assembly 200, which are fixed to the two fixed assemblies 500 on the left side. The active component 700 is located on the right side inside component 200. The active component 700 is fixed to the two fixed components 500 on the right side. The adapter component 800 is connected to the top of the active component 700 inside the welding component 200. The telescopic component 900 is connected to the top of the fixed component 500 inside the welding component 200. By rotating component 100, the welding component 200 can be driven to temporarily weld and fix the reinforcing bars. Before welding, the active component 700 and the driven component 600 can be triggered by the adapter component 800 to trigger the fixed component 500 to fix the reinforcing bars on both sides. When it is necessary to delay the welding of reinforcing bars, a section of reinforcing bar of the required length is placed in the docking component 400 inside the two fixed components 500 on the left side during the equipment stage. The driven component 600, the two fixed components 500 on the left side, and the docking component 400 are triggered by the telescopic component 900 to fix the reinforcing bar. Then, the above operation is continued to connect the prepared reinforcing bar and the reinforcing bar that needs to be extended.

[0038] Specifically, such as Figure 3 In the rotating assembly 100, there are two shells: a split shell 101, which is composed of two shells; an open ring 102, which is disposed inside the split shell 101 and rotatably connected to it; the split shell 101, composed of two shells, facilitates the installation, disassembly, and maintenance of the open ring 102; a first tooth 103 is fixed to the outer wall of the open ring 102; and a motor 104 is fixed to the end face of the split shell 101. The drive end of the motor 104 passes through the split shell 101 and is connected to a gear 105. The gear 105 meshes with the first tooth 103. In use, the motor 104 drives the gear 105 to drive the first tooth 103, thereby rotating the open ring 102 inside the split shell 101. This can drive the welding assembly 200 and the acquisition device 300 on the open ring 102 to rotate, thus enabling the welding of the outer wall of the reinforcing bar. The acquisition device 300 can continuously acquire the welding effect.

[0039] Furthermore, such as Figure 4 In the process, the welding assembly 200 includes a robotic arm 201 fixed to the inner wall of the open ring 102 and a welding device 202 fixed to the end of the robotic arm 201. The robotic arm 201 can drive the welding device 202 to extend and retract, and can weld various types of steel bars.

[0040] Furthermore, such as Figure 5 In the process, the docking assembly 400 includes a housing 401 bolted to the top of the split housing 101. The top of the housing 401 is detachable and has a hanging ear for connecting to a mobile device or a suspension device. Limiting screws 402 are bolted to both sides of the housing 401. Four opening plates 403 are fixed to the bottom of the housing 401. Gaskets 404 are fixed to the openings of the opening plates 403.

[0041] Furthermore, such as Figure 6 In the middle, the fixing component 500 includes a pressing plate 501 rotatably connected to one side of the bottom end of the opening plate 403, a soft pad 502 fixed to the top of the pressing plate 501, a second tooth 503 fixed to the outer wall of the rotating end of the pressing plate 501, and a toothed plate 504 sliding on the opening plate 403 located on one side of the pressing plate 501. The top of the toothed plate 504 penetrates the outer shell 401. The toothed plate 504 and the second tooth 503 mesh with each other. In use, by moving the toothed plate 504 downward, the second tooth 503 can be driven, so that the pressing plate 501 can be driven by the second tooth 503 to rotate into the opening of the opening plate 403. Thus, the pressing plate 501 can drive the soft pad 502 to press the steel bar, and the steel bar will also press the pad 404 in the opening plate 403, thereby adapting to the fixing of various steel bars.

[0042] Furthermore, such as Figure 7 In the driven component 600, there is a first force plate 601 that slides on the left side of the inner wall of the outer casing 401, a first spring 602 fixed between the first force plate 601 and the outer casing 401, and the first force plate 601 is fixed to two toothed plates 504 on the left side. In use, the top cover of the outer casing 401 is removed, and then the limiting screw 402 is removed to take out the first force plate 601.

[0043] Furthermore, such as Figure 7 In the active component 700, there are two force plates 701 that slide on the right side of the inner wall of the outer casing 401, a second spring 702 fixed between the second force plate 701 and the outer casing 401, and a linkage plate 703 fixed to the top of the second force plate 701 located on the top of the first force plate 601. The second force plate 701 is fixed to two toothed plates 504 on the right side. In use, the top cover of the outer casing 401 is removed, and then the limiting screw 402 is removed to take out the second force plate 701.

[0044] Furthermore, such as Figure 7In the middle, the adapter component 800 includes an electric push-pull rod 801 fixed to the inner wall of the outer casing 401 corresponding to the top of the second force plate 701, a transmission plate 802 fixed to the drive end of the electric push-pull rod 801, two pressure springs 803 fixed between the transmission plate 802 and the second force plate 701, the elastic force of the pressure springs 803 being greater than that of the first spring 602 and the second spring 702, and a button 804 fixed to the inner wall of the outer casing 401 corresponding to the bottom of the transmission plate 802. The button 804 is adapted to the motor 104. In use, the electric push-pull rod 801 drives the transmission plate 802, the pressure springs 803, and the second force plate 701. The second force plate 701 can drive the two toothed plates 504 on the right side to move downwards. At the same time, the second force plate 701 will drive the linkage plate 70. 3. Press down the first force plate 601 and the two toothed plates 504 on the left, so that the four toothed plates 504 will move downward to trigger the fixing component 500. When the electric push-pull rod 801 drives the transmission plate 802 to squeeze the pressure spring 803, the elastic space of the pressure spring 803 can press down the second force plate 701, the linkage plate 703, the first force plate 601, and the toothed plates 504 as much as possible, so as to be able to fix and position various types of steel bars. After the triggering work is completed, the transmission plate 802 will press the button 804 to trigger the motor 104 to operate. At this time, the motor 104 can drive the subsequent structure and its welding component 200 and the acquisition device 300 to rotate around the steel bar, and the welding component 200 can perform welding work around the steel bar, and the acquisition device 300 can collect data during welding.

[0045] Furthermore, such as Figure 7 In the telescopic assembly 900, there are telescopic rods 901 fixed to the inner wall of the outer shell 401 corresponding to the top of the first force plate 601, and extrusion discs 902 fixed to the driving end of the telescopic rods 901. In use, when it is necessary to extend the steel bar to be welded, the steel bar is placed in the two open plates 403 on the left side, and the extrusion rods 901 drive the extrusion discs 902 to press down. The extrusion discs 902 will then extrude the first force plate 601 and the two toothed plates 504 on the left side, which can pre-fix the steel bar on this side. Then, the device is moved to the steel bar that needs to be extended, and the electric push-pull rod 801 and its subsequent structure are activated to fix the steel bar that needs to be extended. At this time, welding can be carried out.

[0046] In use, the device is moved to the two steel bars to be welded using a mobile or suspension device. The two open plates 403 on the left correspond to the left steel bar, and the two open plates 403 on the right correspond to the right steel bar. Then, the electric push-pull rod 801 drives the transmission plate 802, the pressure spring 803, and the second force plate 701. The second force plate 701 can drive the two toothed plates 504 on the right to move downward. At the same time, the second force plate 701 will drive the linkage plate 703 to press down the first force plate 601 and the two toothed plates on the left. 504, thus the four toothed plates 504 will move downward to trigger the fixing component 500. Because the electric push-pull rod 801 drives the transmission plate 802 to compress the pressure spring 803, the elastic space of the pressure spring 803 can press down the second force plate 701, the linkage plate 703, the first force plate 601, and the toothed plates 504 as much as possible, thus adapting to various types of steel bars for fixing and positioning. After the triggering work is completed, the transmission plate 802 will press the button 804 to trigger the motor 104 to operate. The motor 104 can drive the toothed plates... Wheel 105 drives tooth 103, which in turn drives the open ring 102 to rotate within the split shell 101. This rotation drives the welding assembly 200 and the acquisition device 300 on the open ring 102 to rotate, thus enabling welding of the outer wall of the reinforcing bar. The acquisition device 300 can continuously collect the welding effect. At this time, motor 104 can drive the subsequent structure and its welding assembly 200 and acquisition device 300 to rotate around the reinforcing bar. The welding assembly 200 can perform welding work around the reinforcing bar, and the acquisition device 300 can collect data during welding. When it is necessary to extend the reinforcing bar to be welded, the reinforcing bar is placed in the two open plates 403 on the left side. The extrusion rod 901 drives the extrusion plate 902 to press down, which in turn extrudes the first force plate 601 and the two toothed plates 504 on the left side, thus pre-fixing the reinforcing bar on this side. This allows the device to be moved to the reinforcing bar that needs to be extended, and the electric push-pull rod 801 and its subsequent structure to fix the reinforcing bar that needs to be extended. Welding can then be performed.

[0047] In summary, this device enables rapid welding around reinforcing bars, captures images of the welding area during welding, and can correct and fix two reinforcing bars before welding. It is compatible with various types of reinforcing bars, thus avoiding the problem of reinforcing bar misalignment during welding. Furthermore, when the distance between two reinforcing bars is insufficient, this device can easily extend the reinforcing bars to be welded for subsequent welding.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
