Abstract
Description
Technical Field
[0001] This utility model relates to a welding deformation correction device for steel structure components, belonging to the field of steel structure component production technology. Background Technology
[0002] Steel structure components are welded from multiple steel plates. During the welding process, uneven heating can cause various deformations in the steel plates, such as longitudinal shrinkage, transverse shrinkage, and angular deformation. Correction can redistribute the residual welding stress, avoid the adverse effects of stress concentration on the structural bearing capacity, and improve the overall stability.
[0003] Flame straightening is a process that uses an oxyacetylene flame to locally heat the deformed area of a metal component, and then uses the plastic deformation generated by cooling and shrinkage to offset the original residual deformation.
[0004] A search revealed a patent with patent number 201811648400.8, which discloses a method for correcting welding deformation of H-beams using a flame. The method involves using an oxyacetylene flame to bake the deformed welded area of the H-beam flange for a certain period of time. After the baked area cools, the area is baked a second time for a certain period of time, depending on the degree of shrinkage and deformation of the H-beam flange. After the baked area cools, the deformed area of the H-beam flange shrinks, is corrected, and flattened, thus completing the correction of the welded H-beam.
[0005] While the aforementioned patents can achieve the purpose of steel structure straightening, current technology is not comprehensive and has the following drawbacks: 1. Standing on the top surface of the steel structure and using a handheld flame gun to perform flame straightening on localized areas results in uneven flame gun movement speed, leading to unsatisfactory heating of the steel structure components and affecting the straightening effect. 2. The lack of a method for testing the flame straightening effect makes over-straightening prone to occur, further affecting the straightening result.
[0006] To solve one of the above problems, there is an urgent need for a welding deformation correction device for steel structure components. Utility Model Content
[0007] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to achieve a more uniform movement speed of the flame spray gun, better heating effect on steel structure components, and to use the aforementioned correction and detection device to detect the flame correction effect, so as to prevent overcorrection as much as possible. To this end, a welding deformation correction device for steel structure components is provided.
[0008] The steel structure component welding deformation correction device of this utility model includes a walking track and a self-propelled trolley that travels along the length of the walking track. The self-propelled trolley is equipped with a vertical support column, and a horizontal support cantilever is installed at the top of the support column. A first mounting seat and a second mounting seat that can move and be locked along the length of the horizontal support cantilever are installed on the horizontal support cantilever. A gas heating gun and a correction detection device are respectively installed on the first mounting seat and the second mounting seat.
[0009] Preferably, the supporting column includes a bottom sleeve rod and an upper insert rod installed on the self-propelled trolley. The bottom end of the upper insert rod is inserted into the bottom sleeve rod and extends and retracts with the bottom sleeve rod. The top end of the upper insert rod is fixedly connected to the horizontal support cantilever. Side plates A and B are fixed on both sides of the upper insert rod, respectively. A left screw and a right screw are fixed on the lower surfaces of side plates A and B, respectively. Side plates C and D are fixed on both sides of the bottom sleeve rod, respectively. Through holes A and B are respectively provided on side plates C and D for the left screw and right screw to pass through. A nut A supporting the upper surface of side plate C is threaded onto the left screw, and a nut B supporting the upper surface of side plate D is threaded onto the right screw.
[0010] By rotating nuts A and B to change their positions on the left and right screws, the depth of the upper insert rod inserted into the lower sleeve rod is changed, thereby achieving height adjustment of the horizontal support cantilever, allowing the air gun and straightening detection device to act on the surface of the steel plate.
[0011] Preferably, a horizontal screw parallel to the horizontal support cantilever is provided above the horizontal support cantilever, and end plates A and B are fixed at both ends of the horizontal screw, respectively. End plates A and B are fixed at both ends of the horizontal support cantilever.
[0012] Preferably, the first mounting base includes a sliding sleeve A that is sleeved on the horizontal support cantilever and slides in cooperation with the horizontal support cantilever. An L-shaped mounting plate connected to the gas torch is fixed at the bottom of the sliding sleeve A. A limiting plate A is installed at the top of the sliding sleeve A. A horizontal screw passes through the limiting plate A, and nuts C and D are threaded onto the horizontal screw. Nuts C and D are attached to both sides of the limiting plate A.
[0013] Nuts C and D can be used in conjunction with a horizontal screw to lock the limiting plate A onto the horizontal screw. When it is necessary to adjust the position of the sliding sleeve A on the horizontal support cantilever, the operator only needs to use a wrench to adjust nuts C and D away from the limiting plate A. When nuts C and D are away from the limiting plate A, the operator can then adjust the sliding sleeve A along the length of the horizontal support cantilever. After the position of the first mounting seat is adjusted, the operator only needs to use a wrench to adjust nuts C and D towards the limiting plate A to lock the limiting plate A onto the horizontal screw again.
[0014] Preferably, the second mounting base includes a sliding sleeve B that is sleeved on and slides with the horizontal support cantilever. A limiting plate B is mounted on the top of the sliding sleeve B. A horizontal screw passes through the limiting plate B, and nuts E and F are threaded onto the horizontal screw. Nuts E and F are fitted against both sides of the limiting plate B. The adjustment of the first mounting base and the second mounting base is consistent.
[0015] Preferably, the correction detection device is mounted on the sliding sleeve B.
[0016] Preferably, the correction detection device includes a vertical connecting plate connected to a sliding sleeve B. An upper support plate is vertically connected to the bottom end of the vertical connecting plate. A bottom support plate is located below the upper support plate. Optical axes A and B are vertically connected to the upper surface of the bottom support plate. The upper end of optical axis A passes through the sliding sleeve A on the upper support plate and connects to a top plate A. The upper end of optical axis B passes through the sliding sleeve B on the upper support plate and connects to a top plate B. A compression spring is fitted onto optical axis B. A proximity switch for sensing top plate B is located above top plate B. The proximity switch is mounted on the vertical connecting plate via a sensor bracket. A microcontroller is mounted on the vertical connecting plate. The proximity switch is electrically connected to the signal input terminal of the microcontroller. An audible and visual alarm is integrated into the microcontroller. An extension rod is mounted on the bottom support plate, and a roller is mounted at the bottom end of the extension rod.
[0017] The rollers reciprocate along the edge of the steel plate. When the end of the steel plate bends, the compression spring drives the bottom support plate to move away from the upper support plate. The top plate B moves away from the proximity switch and cannot trigger it. When the gas torch performs flame straightening on the steel plate, if the edge of the steel plate is straightened, the straightened steel plate support extension rod moves upward. The optical axis B compresses the compression spring and moves upward. After the top plate B moves upward, it triggers the proximity switch. The proximity switch transmits a signal to the microcontroller and triggers an audible and visual alarm to warn the operator that the straightening is complete and to prevent over-straightening.
[0018] Preferably, the horizontal support cantilever has a circular cross-section.
[0019] Preferably, the self-propelled trolley is equipped with a geared motor, and a drive gear is mounted on the power output shaft of the geared motor. A rack is arranged along the length of the travel track to mesh with the drive gear. Powered by the geared motor, the geared motor drives the drive gear to rotate, and the drive gear meshes with the rack to drive the self-propelled trolley to reciprocate along the length of the travel track.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] The steel structure component welding deformation correction device of this utility model uses a self-propelled trolley to carry the supporting column and horizontal support cantilever back and forth along the length of the walking track. The steel plate to be corrected is placed below the walking track of the gas torch and the correction detection device. The self-propelled trolley, as the power source, moves the gas torch and the correction detection device along the length of the steel plate, which makes the movement speed of the flame torch more uniform and the heating effect on the steel structure component better. The gas torch is used to perform flame correction on the steel plate, thereby improving the correction effect.
[0022] The steel structure component welding deformation correction device of this utility model includes a correction detection device used to detect the flame correction effect and to prevent overcorrection as much as possible.
[0023] The steel structure component welding deformation correction device of this utility model has a roller that reciprocates along the edge of the steel plate. When the end of the steel plate bends, the compression spring drives the bottom support plate to move away from the upper support plate. The top plate B is away from the proximity switch and cannot trigger the proximity switch. When the gas torch performs flame correction on the steel plate, if the edge of the steel plate is corrected, the corrected steel plate support extension rod moves upward, the optical axis B compresses the compression spring and moves upward. After the top plate B moves upward, it triggers the proximity switch. The proximity switch transmits a signal to the microcontroller and generates an audible and visual alarm to warn the operator that the correction has been completed and to promptly turn off or remove the gas torch to prevent overcorrection.

[0031] The present invention will be further described below with reference to the accompanying drawings:
[0032] The present invention will be further described below through specific embodiments, but it is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0033] Example 1, as Figure 1-2 As shown, the steel structure component welding deformation correction device includes a walking track 1 and a self-propelled trolley 2 that travels along the length of the walking track 1. A vertical support column 3 is installed on the self-propelled trolley 2. A horizontal support cantilever 4 is installed at the top of the support column 3. A first mounting seat 5 and a second mounting seat 6 that can move and be locked along the length of the horizontal support cantilever 4 are installed on the horizontal support cantilever 4. An air heating gun 7 and a correction detection device 8 are respectively installed on the first mounting seat 5 and the second mounting seat 6.
[0034] Steel structure components are welded from multiple steel plates. During the welding process, uneven heating can cause various deformations in the steel plates, such as longitudinal shrinkage, transverse shrinkage, and angular deformation. Correction can redistribute the residual welding stress, avoid the adverse effects of stress concentration on the structural bearing capacity, and improve the overall stability.
[0035] Flame straightening is a process that uses an oxyacetylene flame to locally heat the deformed area of a metal component to 600-800℃, and then uses the plastic deformation generated by cooling and shrinkage to offset the original residual deformation.
[0036] The self-propelled trolley 2 described in this application, carrying the supporting column 3 and the horizontal supporting cantilever 4, reciprocates along the length of the travel track 1. The steel plate 15 to be straightened is placed below the travel path of the gas torch 7 and the straightening detection device 8. The self-propelled trolley 2, carrying the gas torch 7 and the straightening detection device 8, moves along the length of the steel plate 15, which makes the movement speed of the flame torch more uniform and improves the heating effect on the steel structure components. The gas torch 7 is used to perform flame straightening on the steel plate 15. The straightening detection device 8 is used to detect the flame straightening effect and prevent over-straightening as much as possible.
[0037] Example 2, as Figure 1-4 As shown, the steel structure component welding deformation correction device includes a walking track 1 and a self-propelled trolley 2 that travels along the length of the walking track 1. A vertical support column 3 is installed on the self-propelled trolley 2. A horizontal support cantilever 4 is installed at the top of the support column 3. A first mounting seat 5 and a second mounting seat 6 that can move and be locked along the length of the horizontal support cantilever 4 are installed on the horizontal support cantilever 4. An air heating gun 7 and a correction detection device 8 are respectively installed on the first mounting seat 5 and the second mounting seat 6.
[0038] Furthermore, the supporting column 3 includes a bottom sleeve rod 3.1 and an upper insert rod 3.2 mounted on the self-propelled trolley 2. The bottom end of the upper insert rod 3.2 is inserted into the bottom sleeve rod 3.1 and extends and retracts in cooperation with the bottom sleeve rod 3.1. The top end of the upper insert rod 3.2 is fixedly connected to the horizontal support cantilever 4. Side plates A3.3 and B3.4 are fixed on both sides of the upper insert rod 3.2, respectively. Left-side screws are fixed on the lower surfaces of the side plates A3.3 and B3.4, respectively. Rod 3.7 and right-side screw 3.8 are respectively fixed to the two sides of the bottom sleeve rod 3.1, with side plates C3.5 and D3.6 respectively. The side plates C3.5 and D3.6 are respectively provided with through holes A and B for the left-side screw 3.7 and right-side screw 3.8 to pass through. The left-side screw 3.7 is threaded with a nut A3.9 supported on the upper surface of the side plate C3.5, and the right-side screw 3.8 is threaded with a nut B3.10 supported on the upper surface of the side plate D3.6.
[0039] By rotating nuts A3.9 and B3.10 to change their positions on the left screw 3.7 and right screw 3.8, the depth of the upper insert rod 3.2 inserted into the lower sleeve rod 3.1 is changed, thereby achieving height adjustment of the horizontal support cantilever 4, so that the gas torch 7 and the straightening and detection device 8 can act on the surface of the steel plate 15.
[0040] Furthermore, a horizontal screw 11 parallel to the horizontal support cantilever 4 is provided above it. End plates A9 and B10 are fixed at both ends of the horizontal screw 11, respectively. End plates A9 and B10 are fixed at both ends of the horizontal support cantilever 4.
[0041] Furthermore, the first mounting base 5 includes a sliding sleeve A5.1 that is sleeved on the horizontal support cantilever 4 and slides in cooperation with the horizontal support cantilever 4. The bottom of the sliding sleeve A5.1 is fixed with an L-shaped mounting plate 5.5 that is connected to the gas torch 7. The top of the sliding sleeve A5.1 is fitted with a limiting plate A5.2. The horizontal screw 11 passes through the limiting plate A5.2, and the horizontal screw 11 is threaded with nuts C5.3 and D5.4. Nuts C5.3 and D5.4 are attached to both sides of the limiting plate A5.2.
[0042] Nuts C5.3 and D5.4 are used in conjunction with the horizontal screw 11 to lock the limiting plate A5.2 onto the horizontal screw 11. When it is necessary to adjust the position of the sliding sleeve A5.1 on the horizontal support cantilever 4, the operator only needs to use a wrench to adjust nuts C5.3 and D5.4 away from the limiting plate A5.2. When nuts C5.3 and D5.4 are away from the limiting plate A5.2, the operator can then adjust the sliding sleeve A5.1 along the length of the horizontal support cantilever 4. After the position of the first mounting seat 5 is adjusted, the operator only needs to use a wrench to adjust nuts C5.3 and D5.4 towards the limiting plate A5.2 to lock the limiting plate A5.2 onto the horizontal screw 11 again.
[0043] Furthermore, the second mounting base 6 includes a sliding sleeve B6.1 that is sleeved on the horizontal support cantilever 4 and slides in cooperation with the horizontal support cantilever 4. A limiting plate B6.2 is installed on the top of the sliding sleeve B6.1. The horizontal screw 11 passes through the limiting plate B6.2, and nuts E6.3 and F6.4 are threaded onto the horizontal screw 11. Nuts E6.3 and F6.4 are fitted against both sides of the limiting plate B6.2. The adjustment of the first mounting base 5 and the second mounting base 6 is consistent.
[0044] Furthermore, the correction detection device 8 is mounted on the sliding sleeve B6.1.
[0045] Further, the correction and detection device 8 includes a vertical connecting plate 8.3 connected to the sliding sleeve B6.1. An upper support plate 8.2 is vertically connected to the bottom end of the vertical connecting plate 8.3. A bottom support plate 8.1 is disposed below the upper support plate 8.2. Optical axes A8.7 and B8.8 are vertically connected to the upper surface of the bottom support plate 8.1. The upper end of optical axis A8.7 passes through the sliding sleeve A on the upper support plate 8.2 and connects to the top plate A8.10. The upper end of optical axis B8.8 passes through the sliding sleeve B on the upper support plate 8.2 and connects to the top plate B8.11. A compression spring 8.9 is fitted onto the top plate B8.11. A proximity switch 8.12 for sensing the top plate B8.11 is provided above the top plate B8.11. The proximity switch 8.12 is mounted on the vertical connecting plate 8.3 via a sensor bracket 8.4. A microcontroller 8.13 is mounted on the vertical connecting plate 8.3. The proximity switch 8.12 is electrically connected to the signal input terminal of the microcontroller 8.13. The microcontroller 8.13 integrates an audible and visual alarm. An extension rod 8.5 is mounted on the bottom support plate 8.1. A roller 8.6 is mounted at the bottom end of the extension rod 8.5.
[0046] The self-propelled trolley 2, carrying the gas torch 7 and the correction and detection device 8, moves along the length of the steel plate 15, which makes the movement speed of the flame torch more uniform and the heating effect on the steel structure components better. The gas torch 7 is used to perform flame correction on the steel plate 15.
[0047] During the flame straightening process, the roller 8.6 reciprocates along the edge of the steel plate 15. When the end of the steel plate 15 bends, the compression spring 8.9 drives the bottom support plate 8.1 to move away from the upper support plate 8.2. The top plate B8.11 moves away from the proximity switch 8.12 and cannot trigger it. As the gas torch 7 performs flame straightening on the steel plate 15, the edge of the steel plate 15 is gradually straightened. The edge and center of the straightened steel plate 15 are on the same horizontal plane. During the straightening process, the edge of the steel plate 15 can support the extension rod 8.5 to move upward. The optical axis B8.8 gradually compresses the compression spring 8.9 to move upward. After the top plate B8.11 moves upward, it approaches the proximity switch 8.12, triggering the proximity switch 8.12. The proximity switch 8.12 transmits a signal to the microcontroller 8.13 and triggers an audible and visual alarm to warn the operator that the straightening is complete and to promptly turn off or remove the gas torch 7 to prevent over-straightening. Figure 5 As shown.
[0048] Furthermore, the horizontal support cantilever 4 has a circular cross-section.
[0049] Furthermore, a geared motor 12 is installed on the self-propelled vehicle 2. A drive gear 13 is mounted on the power output shaft of the geared motor 12, and a rack 14 is arranged along the length direction of the travel track 1 to mesh with the drive gear 13. Powered by the geared motor 12, the geared motor 12 drives the drive gear 13 to rotate. The drive gear 13 meshes with the rack 14 to drive the self-propelled vehicle 2 to reciprocate along the length direction of the travel track 1. Alternatively, an existing remote control assembly can be added, allowing the operator to control the forward, reverse, and stop movements of the geared motor using a remote control, thus enabling the self-propelled vehicle 2 to move forward, backward, and park.
[0050] The steel structure component welding deformation correction device of this utility model utilizes a self-propelled trolley carrying a support column and a horizontal support cantilever to reciprocate along the length of the travel track. The steel plate to be corrected is placed below the travel track of the gas torch and the correction detection device. The self-propelled trolley carrying the gas torch and the correction detection device moves along the length of the steel plate, which makes the movement speed of the flame torch more uniform and the heating effect on the steel structure component better. The gas torch is used to perform flame correction on the steel plate.
[0051] The steel structure component welding deformation correction device of this utility model includes a correction detection device used to detect the flame correction effect and to prevent overcorrection as much as possible.
[0052] The steel structure component welding deformation correction device of this utility model has a roller that reciprocates along the edge of the steel plate. When the end of the steel plate bends, the compression spring drives the bottom support plate to move away from the upper support plate. The top plate B is away from the proximity switch and cannot trigger the proximity switch. When the gas torch performs flame correction on the steel plate, if the edge of the steel plate is corrected, the corrected steel plate support extension rod moves upward, the optical axis B compresses the compression spring and moves upward. After the top plate B moves upward, it triggers the proximity switch. The proximity switch transmits a signal to the microcontroller and generates an audible and visual alarm to warn the operator that the correction has been completed and to promptly turn off or remove the gas torch to prevent overcorrection.
