Description

Technical Field

[0001] The present invention relates to the technical field of steel bar skeleton welding, and in particular to a cap beam steel bar skeleton welding device. Background Art

[0002] The cap beam reinforcement skeleton is a steel structure system used to support the cap beam (the transverse load-bearing member at the top of the pier or abutment) in bridge engineering. Its function is to transfer the bending moment, shear force and other loads borne by the cap beam to the lower structure through the reasonable arrangement of steel bars. At the same time, it works together with concrete to improve the overall stiffness and crack resistance of the structure.

[0003] The application document with publication number CN116252089A discloses a cap beam skeleton piece welding positioning device, including an operating table, on which the cap beam skeleton piece to be welded is placed; the positioning clamping mechanism includes a No. 1 cylinder, which is fixed to the bottom of the operating table through a connecting plate, and the output end of the No. 1 cylinder points to the through slot and is fixed with an L-shaped rod, and a guide groove is provided on the horizontal part of the L-shaped rod, and a clamping plate is symmetrically slidably connected in the guide groove, and the end of the screw rod is fixed to the output end of the motor, and the motor is horizontally fixed to the vertical end of the L-shaped rod; the welding positioning device, through the position of the through slot, enables the steel bars to be placed according to the position point of the through slot, which plays a positioning role, and at the same time, the setting of the positioning clamping mechanism can simultaneously clamp and fix the steel bars, and simultaneously release the steel bars. Compared with operating each fastening structure one by one, the setting of the positioning clamping mechanism can effectively improve the positioning and fixation of the cap beam skeleton piece.

[0004] When welding the existing cap beam reinforcement skeleton, a U-shaped locking block is generally set on the surface of the mold base, and the contact position of the straight steel bar and the bent steel bar is set in the locking block and compressed with lateral pressure. However, internal stress is generated when the steel bars are welded, which causes both the straight steel bar and the bent steel bar to deform, resulting in an uneven weld surface. Moreover, the reinforcement skeleton needs to be welded on both sides. After the deformation occurs, it is difficult to fix it when welding the other side. In addition, the position of the locking block cannot be adjusted. It needs to be turned over and then rotated to change its position to adapt to the locking block, which is time-consuming and labor-intensive, affecting work efficiency. Summary of the Invention

[0005] The present invention provides a cap beam reinforcement frame welding device, which aims to solve the technical problems in the related art that the existing cap beam reinforcement frame generates internal stress during welding, causing deformation of both straight and bent reinforcement bars, resulting in an uneven weld surface. In addition, the reinforcement frame needs to be welded on both sides, making it difficult to fix it when welding the other side after deformation. In addition, the position of the locking block cannot be adjusted, requiring it to be turned over and then rotated to adjust its position to match the locking block, which is time-consuming and labor-intensive, affecting work efficiency.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 10 As shown, a specific embodiment of a cap beam reinforcement skeleton welding device of the present invention is shown. For ease of understanding, straight steel bars 13 and bent steel bars 14 are used as application scenarios of the present invention. The cap beam reinforcement skeleton welding device includes a bearing module and a positioning module.

[0036] like Figure 1 and Figure 2 As shown, the carrying module includes a workbench 10 and a base 12. The workbench 10 is fixedly installed above the base 12. In this embodiment, the workbench 10 and the base 12 are both rectangular structures. The length directions of the two are consistent, and the length direction is defined as the left-right direction, and the width direction is defined as the front-back direction.

[0037] The workbench 10 is a rectangular plate-like structure located on the ground. A row of fixing holes 11 is provided on both the front and rear sides of the upper surface of the workbench 10. The fixing holes 11 are vertically continuous and rectangular in structure, with the length of the fixing holes 11 extending in the front-to-back direction. It should be noted that the two rows of fixing holes 11 correspond to each other in the front-to-back direction.

[0038] The base 12 is a box-like structure with a hollow interior and an open top. The fixing holes 11 on the workbench 10 communicate with the interior of the base 12, and the positioning module is mounted within the base 12. In other words, during installation, the device requires a recessed pit in the ground to accommodate the base 12, with the base 12 positioned below the ground and the workbench 10 above it. Straight rebar 13 and bent rebar 14 can be placed on the top surface of the workbench 10. The positioning module secures the straight and bent rebars 13 and 14 together, allowing a worker to weld the two bars while standing on the workbench 10.

[0039] like Figure 4As shown, the positioning module comprises two positioning units spaced apart from each other. Both units are structurally identical, each including a moving mechanism and a positioning mechanism. The positioning mechanisms in the front and rear positioning units correspond one-to-one with the front and rear rows of fixing holes 11, respectively. The positioning mechanisms clamp and secure the welds on the straight and bent bars 13 and 14, while the moving mechanism drives the positioning mechanisms up and down, as well as forward and backward, thereby repositioning the positioning mechanisms in the two positioning units.

[0040] The positioning mechanisms each include a horizontal slide 20 , a horizontal slider 21 , a vertical slide 22 and a vertical slider 23 .

[0041] Two horizontal slides 20 are provided, fixedly mounted on the bottom of the base 12 at intervals. Each horizontal slide 20 is rectangular in shape, with its length extending in the front-to-back direction. Each horizontal slide 20 is provided with a track extending in the front-to-back direction, and a horizontal slider 21 is mounted on each horizontal slide 20 for horizontal sliding movement back and forth. The sliders 21 are capable of reciprocating movement on the horizontal slide 20. A drive mechanism (not shown) is also mounted on the sliders 21 to drive the sliders 21 along the horizontal slide 20.

[0042] Each horizontal slider 21 is fixedly mounted with a vertical slide 22. The vertical slide 22 is a rectangular structure and is arranged vertically. A vertical track is provided on the vertical slide 22, and a vertical slider 23 is vertically slidably mounted on the vertical slide 22. The vertical slider 23 can slide back and forth on the vertical slide 22. A drive structure (not shown) is also mounted on the vertical slider 23 to drive the vertical slider 23 to slide on the vertical slide 22.

[0043] In this embodiment, the drive structure comprises a motor and a drive wheel. The motor is fixedly mounted on the slider, and the drive wheel is fixedly mounted on the output end of the motor. The drive wheels are respectively engaged with the slider. When the motor drives the drive wheel to rotate, the slider can slide along the slider. In other embodiments, the drive structure can also be a cylinder or a screw structure.

[0044] The positioning mechanism is fixedly installed between the left and right vertical sliders 23, so as to drive the positioning mechanism to move up and down and forward and backward.

[0045] It is particularly noted that the straight steel bar 13 has two parallel horizontal portions, front and rear, and in this embodiment, the length of the front horizontal portion is greater than the length of the rear horizontal portion (e.g. Figure 1 As shown in FIG, therefore, of the two front and rear positioning units, the left-right length of the positioning mechanism on the front side is greater than the left-right length of the positioning mechanism on the rear side. That is, the two horizontal slides 20 in the moving mechanism on the rear side are located inside the two horizontal slides 20 in the moving mechanism on the front side (as shown in FIG. Figure 4 At the same time, it also facilitates the replacement of the front and rear positioning mechanisms to avoid interference between the two when they move.

[0046] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the positioning mechanism includes a bearing seat 30, a first movable plate 31, a second movable plate 32, a driving screw 33, a driving motor 34, a positioning block 40, a clamping part 41, a bearing platform 42, a pressing plate 44, a lifting seat 51 and a lifting cylinder 54.

[0047] The support base 30 is a rectangular structure with a concave cavity inside. The length of the support base 30 extends in the left-right direction. The left and right ends of the support base 30 are respectively fixedly connected to the two vertical sliders 23 in each moving mechanism, thereby driving the support base 30 to move up and down and forward and backward.

[0048] A second movable plate 32 and a first movable plate 31 are spaced apart and parallel to each other within the support base 30. The second movable plate 32 and the first movable plate 31 are rectangular in structure, and their lengths extend in the left-right direction. The second movable plate 32 and the first movable plate 31 slide horizontally with the support base 30 in a front-to-back manner.

[0049] A drive motor 34 is fixedly mounted on the front side of the support base 30, and a drive screw 33 is rotatably mounted on the inner side of the support base 30. The drive screw 33 is fixedly connected to the output end of the drive motor 34. The drive screw 33 is arranged horizontally, and its axis extends in the front-to-back direction. The drive screw 33 passes through the second movable plate 32 and the first movable plate 31, and the drive screw 33 is threadedly engaged with the second movable plate 32 and the first movable plate 31. The drive screw 33 is provided with two sections of thread at the front and rear, respectively engaging with the second movable plate 32 and the first movable plate 31, and the two sections of thread are in opposite directions. Therefore, when the drive motor 34 drives the drive screw 33 to rotate, it can drive the second movable plate 32 and the first movable plate 31 to move closer or farther away at the same time.

[0050] Multiple positioning assemblies are spaced apart along the left-right direction between the second movable plate 32 and the first movable plate 31. Each set of positioning assemblies includes a positioning block 40 fixedly mounted on the second movable plate 32. The positioning block 40 is a rectangular structure, and its length extends in the front-to-back direction. A clamping portion 41 is vertically mounted on the upper surface of the positioning block 40. The clamping portion 41 is fixedly engaged with the positioning block 40 and has a square protrusion.

[0051] A support platform 42 is fixedly mounted on the first movable plate 31 at a position corresponding to the positioning block 40. The length of the support platform 42 also extends in the front-to-back direction. The support platform 42 is flush with the upper surface of the positioning block 40. A first insertion hole 43 extending vertically through the support platform 42 is provided near the front end. The first insertion hole 43 corresponds to the positioning block 40 and has the same width as the positioning block 40. Therefore, when the second movable plate 32 and the first movable plate 31 are close to each other, the positioning block 40 can be inserted into the first insertion hole 43.

[0052] It should be noted in particular that the supporting platform 42 and the positioning block 40 in each positioning assembly are located in a corresponding fixing hole 11 above, and the upper surfaces of the supporting platform 42 and the positioning block 40 are flush with the upper surface of the workbench 10, that is, the clamping portion 41 protrudes from the upper surface of the workbench 10.

[0053] A clamping plate 44 is installed vertically and slidably near the rear side of the supporting platform 42. The clamping plate 44 is an L-shaped structure, and has a vertical section and a horizontal section. The vertical section of the clamping plate 44 passes through the supporting platform 42 from top to bottom. The surface of the vertical section of the clamping plate 44 facing the clamping portion 41 is the clamping surface. When the straight steel bar 13 and the bent steel bar 14 are placed on the upper surface of the workbench 10, they are just located on the upper surface of the supporting platform 42. When the second movable plate 32 and the first movable plate 31 are close to each other, the vertical section of the clamping plate 44 and the clamping portion 41 can clamp the straight steel bar 13 and the bent steel bar 14 (such as Figure 9 ).

[0054] The horizontal section of the clamping plate 44 is provided with a second insertion hole 45 which passes through from top to bottom near the front side, and the second insertion hole 45 corresponds to the size and position of the protrusion on the clamping part 41. When the vertical section of the clamping plate 44 and the clamping part 41 clamp the straight steel bar 13 and the bent steel bar 14, the clamping plate 44 descends, and the horizontal section of the clamping plate 44 descends and abuts above the straight steel bar 13 and the bent steel bar 14, clamping and fixing the straight steel bar 13 and the bent steel bar 14 in the vertical direction. When the horizontal section of the clamping plate 44 descends, the protrusion on the clamping part 41 will be inserted into the second insertion hole 45, that is, the second insertion hole 45 can avoid the protrusion on the clamping part 41, and at the same time enhance the stability of the clamping part 41 and the clamping plate 44.

[0055] It is particularly emphasized that the two positioning components in the left and right directions are a group, that is, the two positioning components can clamp and fix one of the welding parts on one side of the straight steel bar 13 and the bent steel bar 14 (such as Figure 9 As shown in FIG, and the two positioning components can be fixed on both sides of the welding part, the middle position of the welding part can be welded first during welding to ensure the stability of the welding.

[0056] The second movable plate 32 and the first movable plate 31 are both provided with front-to-back clearance holes 50 at positions corresponding to the positioning components along the left-right direction. Each positioning component is provided with a corresponding lift seat 51. The length of the lift seat 51 extends in the front-to-back direction, and the front and rear ends of the lift seat 51 are respectively inserted into the two corresponding front and rear clearance holes 50. The clearance holes 50 allow the lift seats 51 to avoid movement when the second movable plate 32 and the first movable plate 31 move. Adjacent lift seats 51 are fixedly connected by a connecting plate 53, and a lifting cylinder 54 is fixedly installed at the bottom of the support base 30. The telescopic portion of the lifting cylinder 54 is fixedly connected to the connecting plate 53, allowing the lifting cylinder 54 to drive all the lift seats 51 to rise and fall together.

[0057] Each lifting seat 51 is provided with a movable groove 52 arranged in the front-to-back direction. The lower end of each holding plate 44 in the positioning assembly slides with the movable groove 52 on the corresponding lifting seat 51. When the lifting cylinder 54 is raised or lowered, the lifting seat 51 can drive all the holding plates 44 to rise and fall, thereby vertically fixing the straight steel bars 13 and the bent steel bars 14. At the same time, when the second movable plate 32 and the first movable plate 31 move, the supporting platform 42 drives the holding plates 44 to slide along the movable groove 52 on the holding plates 44, allowing the holding plates 44 to slide forward and backward while also being able to move up and down.

[0058] During operation, the straight steel bar 13 and the bent steel bar 14 are placed at corresponding positions on the workbench 10, and the two horizontal portions of the straight steel bar 13 are respectively located above the front and rear rows of fixing holes 11. Each horizontal portion is located between the clamping portion 41 and the pressing plate 44, and the welding portion of the straight steel bar 13 and the bent steel bar 14 is also located between the clamping portion 41 and the pressing plate 44 (as shown in FIG. Figure 1 As shown). Then the second movable plate 32 and the first movable plate 31 approach each other, and the vertical section of the clamping plate 44 and the clamping portion 41 can clamp and fix the straight steel bar 13 and the bent steel bar 14. At the same time, the clamping plate 44 descends and abuts against the straight steel bar 13 and the bent steel bar 14, clamping and fixing the straight steel bar 13 and the bent steel bar 14 in the vertical direction. Then, welding of the welded parts of the straight steel bar 13 and the bent steel bar 14 begins. Being able to fix all welded parts at the same time not only saves manpower, but also effectively prevents the deformation of the straight steel bar 13 and the bent steel bar 14 during welding. Moreover, the clamping portion 41 and the clamping plate 44 can move back and forth, and can adapt to different numbers of steel bars. The clamping plate 44 can clamp and fix the straight steel bar 13 and the bent steel bar 14 in the vertical direction, further increasing the stability during welding, preventing the steel bars from being warped due to stress, and ensuring the quality of welding.

[0059] When the welding of the first side is completed, the straight steel bar 13 and the bent steel bar 14 are turned over, and then the vertical slider 23 drives the supporting seat 30 to descend, and the rear supporting seat 30 is lower than the height of the front supporting seat 30, and then the horizontal slider 21 drives the front and rear supporting seats 30 to swap positions. That is, since the bent steel bar 14 is Z-shaped, the welding positions of the two horizontal parts on the straight steel bar 13 are different. After the front and rear supporting seats 30 are swapped, they can just adapt to the welding positions on the straight steel bar 13 and the bent steel bar 14 after the flipping, and there is no need to rotate the straight steel bar 13 and the bent steel bar 14 again, saving manpower.

[0060] It should be emphasized that, since the two positioning components in the front and rear directions are staggered, in order to enable the front and rear positioning components to still correspond to the fixing holes 11 after the positions are swapped, in this embodiment, the widths of the two mutually staggered fixing holes 11 are increased (e.g., Figure 10 As shown), one fixing hole 11 can accommodate two positioning components, that is, when the positioning component on the rear side is moved to the front side, the corresponding fixing hole 11 on the front side can also match it.

[0061] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
