Description

Technical Field

[0001] The present invention relates to the technical field of steel bar framework welding, and particularly relates to a cover beam steel bar framework welding device. Background Art

[0002] A cover beam steel bar framework is a steel bar structure system used to support a cover beam (a transverse load-bearing member at the top of a pier or abutment) in bridge engineering. Its function is to transfer loads such as bending moments and shear forces borne by the cover beam to the lower structure by reasonably arranging steel bars, and at the same time work together with concrete to improve the overall stiffness and crack resistance of the structure.

[0003] The application document with the publication number CN116252089A discloses a cover beam framework sheet welding positioning device, including an operating table on which a cover beam framework sheet to be welded is placed; the positioning and clamping mechanism includes a first cylinder, the first cylinder is fixedly connected to the lower part of the operating table through an adapter plate, the output end of the first cylinder points into the through groove and is fixedly connected with an L-shaped rod, a guide groove is opened in the horizontal part of the L-shaped rod, clamping plates are symmetrically and slidably connected in the guide groove, and the end of the lead screw is fixedly connected to the output end of the motor, and the motor is horizontally fixedly connected to the vertical end of the L-shaped rod; this welding positioning device, through the position of the through groove, enables the steel bars to be placed according to the position points of the through groove, playing a positioning role. At the same time, the setting of the positioning and clamping mechanism can clamp and fix the steel bars simultaneously and synchronously, and release the steel bars synchronously and simultaneously. Compared with operating each fastening structure one by one, the setting of this positioning and clamping mechanism can effectively improve the positioning and fixing of the cover beam framework sheet.

[0004] When welding the existing cover beam steel bar framework, generally, U-shaped locking blocks are arranged on the surface of the formwork table, and the contact positions of straight steel bars and bent steel bars are arranged in the locking blocks and pressed tightly with lateral pressure. However, internal stress will be generated during the welding of the steel bars, resulting in deformation of both the straight steel bars and the bent steel bars, causing the surface of the weld to be uneven. Moreover, the steel bar framework needs to be welded on both sides. It is difficult to fix it when welding the other side after deformation. In addition, the position of the locking block cannot be adjusted, and it is necessary to turn it over and then rotate and adjust the position to fit the locking block, which is time-consuming and laborious and affects work efficiency. Summary of the Invention

[0005] The present invention provides a cover beam steel bar framework welding device, aiming to solve the technical problems in the related art that internal stress will be generated when welding the existing cover beam steel bar framework, resulting in deformation of both the straight steel bars and the bent steel bars, causing the surface of the weld to be uneven. Moreover, the steel bar framework needs to be welded on both sides. It is difficult to fix it when welding the other side after deformation. In addition, the position of the locking block cannot be adjusted, and it is necessary to turn it over and then rotate and adjust the position to fit the locking block, which is time-consuming and laborious and affects work efficiency.

[0006] A welding device for a bent cap steel bar framework according to the present invention includes: a workbench and a base provided below it; two rows of fixing holes are arranged front and back on the workbench, and a positioning module is arranged inside the base. The positioning module includes two positioning units arranged at intervals front and back. Each positioning unit includes a moving mechanism arranged in the base and a positioning mechanism arranged on the moving mechanism. The moving mechanism can drive the positioning mechanism to lift and slide back and forth so that the positioning mechanisms in the two positioning units exchange positions; the positioning mechanism includes a bearing seat arranged at the output end of the moving mechanism. Two moving plates are horizontally slidably installed on the bearing seat at intervals front and back. A driving member is arranged on the bearing seat to drive the two moving plates to approach or move away from each other. A plurality of positioning components respectively corresponding to the fixing holes are arranged at intervals left and right on the moving plates; the positioning component includes a positioning block and a bearing table which are arranged corresponding to each other front and back and are respectively arranged on the two moving plates, and both are located in the fixing holes. A clamping portion is arranged on the positioning block. A pressing plate is vertically slidably installed on the bearing table. The pressing plate has a vertical section opposite to the clamping portion front and back and a horizontal section for vertically clamping the steel bar.

[0007] Beneficial effects: Place the straight steel bar and the bent steel bar at the corresponding positions on the workbench. The second moving plate and the first moving plate approach each other. The vertical section of the pressing plate and the clamping portion can clamp and fix the straight steel bar and the bent steel bar. At the same time, the pressing plate descends and abuts against the upper part of the straight steel bar and the bent steel bar to clamp and fix the straight steel bar and the bent steel bar in the vertical direction. All welding parts can be fixed simultaneously, saving manpower and avoiding deformation of the steel bar caused by the influence of stress during welding, ensuring the flatness of the steel bar during welding. Moreover, the clamping portion and the pressing plate can move back and forth to adapt to different numbers of steel bars. The pressing plate can position the steel bar in the vertical direction to further prevent the steel bar from warping during welding, effectively ensuring the welding quality of the welded part of the steel bar. When welding the first side is completed, turn over the straight steel bar and the bent steel bar, and at the same time, exchange the positions of the front and rear bearing seats. The positioning blocks and bearing tables on the bearing seats can just adapt to the welding positions of the steel bars after turning over, and there is no need to rotate the steel bars again, saving manpower.

[0008] Preferably, the moving mechanism includes horizontal sliding seats arranged at intervals left and right in the base. Horizontal sliders are horizontally slidably installed on the horizontal sliding seats front and back. A vertical sliding seat is vertically arranged on the horizontal slider. A vertical slider is vertically slidably installed on the vertical sliding seat. The vertical slider is fixedly connected to the bearing seat.

[0009] The effect is that it can drive the bearing seat to lift and slide back and forth to realize the exchange of positions of the front and rear bearing seats.

[0010] Preferably, the moving plate includes a first moving plate and a second moving plate. A driving lead screw arranged horizontally from front to back is rotatably installed on the bearing seat. The driving lead screw is in threaded fit with the first moving plate and the second moving plate, and there are two threads with opposite directions on the driving lead screw, so that the first moving plate and the second moving plate approach or move away from each other.

[0011] The effect is that: when the driving lead screw rotates, the first moving plate and the second moving plate can approach or move away from each other, realizing the clamping and loosening of the steel bars.

[0012] Preferably, a plurality of lifting seats are arranged at left - right intervals between the first moving plate and the second moving plate. The lifting seats correspond to the positioning components one by one, and are fixedly connected between the lifting seats. The pressing plates are respectively in front - to - back horizontal sliding fit with the corresponding lifting seats. An elevating cylinder connected to the lifting seats is provided at the bottom of the bearing seat.

[0013] The effect is that: the elevating cylinder drives all the lifting seats to rise and fall, thereby driving all the pressing plates to clamp and fix the steel bars in the vertical direction.

[0014] Preferably, a first jack that penetrates up and down is provided on the bearing table, and the first jack corresponds to the positioning block.

[0015] Preferably, a second jack that penetrates up and down is opened on the horizontal section of the pressing plate, and the second jack corresponds to the clamping part.

[0016] Preferably, the bearing seat is of a rectangular structure and has a concave cavity communicated with the fixing hole inside.

[0017] Preferably, the length of the bearing seat in the front - side positioning unit is greater than the length of the bearing seat in the rear - side positioning unit, and the horizontal sliding seat in the rear - side positioning unit is located inside the horizontal sliding seat in the front - side positioning unit.

[0018] Preferably, the upper surfaces of the bearing table and the positioning block are flush with the upper surface of the workbench, and the clamping part and the pressing plate protrude from the upper surface of the workbench.

[0019] The effect is that: the clamping part and the pressing plate protrude from the upper surface of the workbench, and can clamp and fix the steel bars placed on the upper surface of the workbench.

[0020] Preferably, the fixing holes are all rectangular holes, and the length direction thereof extends along the front - to - back direction.

[0021] With the above technical solution, the beneficial effects of the present invention are as follows: Place the straight steel bars and bent steel bars at the corresponding positions on the workbench. The second moving plate and the first moving plate approach each other. The vertical section of the pressing plate and the clamping part can clamp and fix the straight steel bars and bent steel bars. At the same time, the pressing plate descends and abuts above the straight steel bars and bent steel bars to clamp and fix them in the vertical direction. It can fix all the welding parts at the same time, saving manpower and avoiding the deformation of the steel bars caused by the influence of the stress during welding, ensuring the flatness of the steel bars during welding. Moreover, the clamping part and the pressing plate can move back and forth, which can adapt to different numbers of steel bars. The pressing plate can position the steel bars in the vertical direction, further preventing the steel bars from warping during welding, effectively ensuring the welding quality of the welded parts of the steel bars. When welding the first side is completed, turn over the straight steel bars and bent steel bars, and at the same time, the front and rear two bearing seats are adjusted in position. The positioning blocks on the bearing seats and the bearing platform can just adapt to the welding positions of the steel bars after turning over, without the need to rotate the steel bars again, saving manpower.

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0034] As Figures 1 to 10 shown, in a specific embodiment of a bent cap steel bar skeleton welding device of the present invention, for the convenience of understanding, the straight steel bars 13 and the bent steel bars 14 are used as the application scenarios of the present invention. The bent cap steel bar skeleton welding device includes a bearing module and a positioning module.

[0035] As Figure 1 shown, the bearing module includes a workbench 10 and a base 12. The workbench 10 is fixedly installed above the base 12. In this embodiment, both the workbench 10 and the base 12 are rectangular structures, and their length directions are the same. The length direction is defined as the left - right direction, and the width direction is defined as the front - back direction. Figure 2 The workbench 10 is a rectangular plate - like structure and is located on the ground. A row of fixed holes 11 are provided on the front and back of the upper surface of the workbench 10. The fixed holes 11 penetrate up and down and are rectangular structures. The length direction of the fixed holes 11 extends along the front - back direction. It should be particularly noted that the two rows of fixed holes 11 correspond to each other in the front - back direction.

[0036] The base 12 is a box - like structure with a hollow interior and an open upper surface. The fixed holes 11 on the workbench 10 are communicated with the interior of the base 12, and the positioning module is installed inside the base 12. That is, when installing this device, a pit for accommodating the base 12 needs to be set on the ground so that the base 12 is located below the ground and the workbench 10 is located on the ground. The straight steel bars 13 and the bent steel bars 14 can be placed on the upper surface of the workbench 10. The straight steel bars 13 and the bent steel bars 14 are fixed together by the positioning module, and then workers can stand on the workbench 10 to weld the welding positions of the straight steel bars 13 and the bent steel bars 14.

[0037]

[0038] Figure 4 As Figure 4As shown in the figure, the positioning module includes two positioning units arranged at intervals before and after. The structures of the two positioning units are the same. Each positioning unit includes a moving mechanism and a positioning mechanism. The positioning mechanisms in the front and rear positioning units respectively correspond to the front and rear rows of fixing holes 11 one by one. The positioning mechanism is used to clamp and fix the welding parts on the straight steel bar 13 and the bent steel bar 14, and the moving mechanism is used to drive the positioning mechanism to lift and move back and forth, so as to replace the positions of the positioning mechanisms in the two positioning units.

[0039] The positioning mechanisms both include a horizontal sliding seat 20, a horizontal sliding block 21, a vertical sliding seat 22 and a vertical sliding block 23.

[0040] There are two horizontal sliding seats 20, which are fixedly installed at the bottom of the base 12 at intervals left and right. The horizontal sliding seat 20 is of a rectangular structure, and its length direction extends along the front and rear directions. The horizontal sliding seat 20 is provided with a track extending along the front and rear directions, and the horizontal sliding blocks 21 are horizontally slidably installed on the horizontal sliding seat 20 back and forth. The horizontal sliding block 21 can reciprocate back and forth on the horizontal sliding seat 20. A driving structure (not shown in the figure) is also installed on the horizontal sliding block 21, and the driving structure is used to drive the horizontal sliding block 21 to slide on the horizontal sliding seat 20.

[0041] Vertical sliding seats 22 are fixedly installed on the horizontal sliding blocks 21 respectively. The vertical sliding seat 22 is of a rectangular structure and is arranged vertically. The vertical sliding seat 22 is provided with a vertically arranged track, and the vertical sliding blocks 23 are vertically slidably installed on the vertical sliding seat 22. The vertical sliding block 23 can reciprocate up and down on the vertical sliding seat 22. A driving structure (not shown in the figure) is also installed on the vertical sliding block 23, and the driving structure is used to drive the vertical sliding block 23 to slide on the vertical sliding seat 22.

[0042] In this embodiment, the driving structure is a motor and a driving wheel. The motors are respectively fixedly installed on the sliding blocks, and the output ends of the motors are fixedly installed with driving wheels, and the driving wheels are respectively in transmission cooperation with the sliding seats. Therefore, when the motors drive the driving wheels to rotate, the sliding blocks can slide along the sliding seats. In other embodiments, the driving structure can also be a cylinder or a lead screw structure.

[0043] The positioning mechanism is fixedly installed between the left and right vertical sliding blocks 23, so as to drive the positioning mechanism to lift and move back and forth.

[0044] It should be particularly noted that the straight steel bar 13 has two parallel horizontal parts before and after, and in this embodiment, the length of the front horizontal part is greater than the length of the rear horizontal part (as Figure 1 shown), so in the front and rear positioning units, the length of the front positioning mechanism in the left and right directions is greater than the length of the rear positioning mechanism in the left and right directions. That is, the two horizontal sliding seats 20 in the moving mechanism located at the rear are located inside the two horizontal sliding seats 20 in the moving mechanism located at the front (asFigure 4 As shown). At the same time, it is also convenient for the front and rear positioning mechanisms to change positions, avoiding interference when the two move.

[0045] Such as 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 moving plate 31, a second moving plate 32, a driving lead screw 33, a driving motor 34, a positioning block 40, a clamping part 41, a bearing table 42, a pressing plate 44, a lifting seat 51 and a lifting cylinder 54.

[0046] The bearing seat 30 is of a rectangular structure and has a concave cavity inside. The length direction of the bearing seat 30 extends along the left - right direction. The left and right ends of the bearing seat 30 are respectively fixedly connected to two vertical sliders 23 in each moving mechanism, thereby driving the bearing seat 30 to lift and move forward and backward.

[0047] Inside the bearing seat 30, the second moving plate 32 and the first moving plate 31 are arranged in parallel at intervals in the front - rear direction. The second moving plate 32 and the first moving plate 31 are of rectangular structures, and the length directions of the second moving plate 32 and the first moving plate 31 both extend along the left - right direction. The second moving plate 32 and the first moving plate 31 are horizontally slidably matched with the bearing seat 30 in the front - rear direction.

[0048] A driving motor 34 is fixedly installed on the front side of the bearing seat 30, and a driving lead screw 33 is rotatably installed inside the bearing seat 30. The driving lead screw 33 is fixedly connected to the output end of the driving motor 34. The driving lead screw 33 is horizontally arranged, and its axis extends along the front - rear direction. The driving lead screw 33 passes through both the second moving plate 32 and the first moving plate 31, and the driving lead screw 33 is threadedly matched with both the second moving plate 32 and the first moving plate 31. There are two sections of threads on the driving lead screw 33 in the front - rear direction. The two sections of threads are respectively matched with the second moving plate 32 and the first moving plate 31, and the directions of the two sections of threads are opposite. Thus, when the driving motor 34 drives the driving lead screw 33 to rotate, it can drive the second moving plate 32 and the first moving plate 31 to approach or move away from each other simultaneously.

[0049] A plurality of positioning components are arranged at intervals in the left - right direction between the second moving plate 32 and the first moving plate 31. Each group of positioning components includes a positioning block 40 fixedly installed on the second moving plate 32. The positioning block 40 is of a rectangular structure, and the length direction of the positioning block 40 extends along the front - rear direction. A clamping part 41 is vertically installed on the upper surface of the positioning block 40. The clamping part 41 is fixedly matched with the positioning block 40, and the clamping part 41 has a square protrusion.

[0050] A bearing platform 42 is fixedly installed at a position corresponding to the positioning block 40 on the first moving plate 31, and the length direction of the bearing platform 42 also extends in the front-back direction. The upper surface of the bearing platform 42 is flush with the upper surface of the positioning block 40, and a first jack 43 penetrating up and down is provided near the front end of the bearing platform 42. The first jack 43 corresponds to the positioning block 40 and has the same width as the latter. Thus, when the second moving plate 32 approaches the first moving plate 31, the positioning block 40 can be inserted into the first jack 43.

[0051] Specifically, the bearing platform 42 and the positioning block 40 in each positioning component are both located in a corresponding fixing hole 11 above, and the upper surfaces of the bearing platform 42 and the positioning block 40 are flush with the upper surface of the workbench 10. That is to say, the clamping part 41 protrudes from the upper surface of the workbench 10.

[0052] A pressing plate 44 is vertically and slidably installed at a position near the rear side of the bearing platform 42. The pressing plate 44 has an L-shaped structure and has a vertical section and a horizontal section. The vertical section of the pressing plate 44 penetrates the bearing platform 42 up and down, and the surface of the vertical section of the pressing plate 44 opposite to the clamping part 41 is a 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 bearing platform 42. When the second moving plate 32 approaches the first moving plate 31, the vertical section of the pressing plate 44 and the clamping part 41 can clamp and fix the straight steel bar 13 and the bent steel bar 14 (as Figure 9 )

[0053] A second jack 45 penetrating up and down is provided at a position near the front side of the horizontal section of the pressing plate 44, and the size and position of the second jack 45 correspond to those of the protrusion on the clamping part 41. After the vertical section of the pressing plate 44 and the clamping part 41 clamp and fix the straight steel bar 13 and the bent steel bar 14, the pressing plate 44 descends, and the horizontal section of the pressing plate 44 will descend and abut against the upper sides of the straight steel bar 13 and the bent steel bar 14 to clamp and fix them in the vertical direction. When the horizontal section of the pressing plate 44 descends, the protrusion on the clamping part 41 will be inserted into the second jack 45. That is to say, the second jack 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 pressing plate 44.

[0054] It should be particularly emphasized that two positioning components in the left-right direction form a group. That is to say, 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 (as Figure 9 shown), and the two positioning components can be fixed on both sides of the welding part. During welding, the middle position of the welding part can be welded first to ensure the stability of welding.

[0055] The second moving plate 32 and the first moving plate 31 are both provided with avoidance through holes 50 that penetrate from front to back at corresponding positions in the left-right direction with respect to the positioning components. Each positioning component is correspondingly provided with a lifting seat 51. The length direction of the lifting seat 51 extends in the front-back direction, and the front and rear ends of the lifting seat 51 respectively penetrate into the front and rear corresponding avoidance through holes 50. The avoidance through holes 50 can avoid the lifting seat 51 when the second moving plate 32 and the first moving plate 31 move. Adjacent two lifting seats 51 are fixedly connected by a connecting plate 53, and a lifting cylinder 54 is fixedly installed at the bottom of the bearing seat 30. The telescopic part of the lifting cylinder 54 is fixedly connected to the connecting plate 53, so that the lifting cylinder 54 can drive all the lifting seats 51 to lift together.

[0056] The lifting seats 51 are all provided with moving grooves 52 arranged in the front-back direction. The lower ends of the pressing plates 44 in each positioning component are slidably matched with the moving grooves 52 on the corresponding lifting seats 51. When the lifting cylinder 54 lifts or lowers, all the pressing plates 44 can be driven to lift or lower through the lifting seats 51, thereby fixing the straight reinforcing bars 13 and the bent reinforcing bars 14 in the vertical direction. At the same time, when the second moving plate 32 and the first moving plate 31 move, the bearing table 42 will drive the pressing plates 44 to slide along the moving grooves 52 on the pressing plates 44, so that the pressing plates 44 can not only slide back and forth, but also perform lifting and lowering movements.

[0057] During work, the straight reinforcing bars 13 and the bent reinforcing bars 14 are placed at corresponding positions on the workbench 10. The two horizontal parts on the straight reinforcing bar 13 are respectively located above the front and rear rows of fixing holes 11. And each horizontal part is located between the clamping part 41 and the pressing plate 44. At the same time, the welded parts of the straight reinforcing bar 13 and the bent reinforcing bar 14 are also located between the clamping part 41 and the pressing plate 44 (as Figure 1 shown). Then the second moving plate 32 and the first moving plate 31 approach each other. The vertical sections of the pressing plates 44 and the clamping part 41 can clamp and fix the straight reinforcing bars 13 and the bent reinforcing bars 14. At the same time, the pressing plates 44 descend and abut against the upper sides of the straight reinforcing bars 13 and the bent reinforcing bars 14 to clamp and fix the straight reinforcing bars 13 and the bent reinforcing bars 14 in the vertical direction. Then the welded parts of the straight reinforcing bars 13 and the bent reinforcing bars 14 are welded. It can fix all the welded parts at the same time, which not only saves manpower, but also effectively prevents the straight reinforcing bars 13 and the bent reinforcing bars 14 from deforming during welding. Moreover, the clamping part 41 and the pressing plate 44 can move back and forth, can adapt to different numbers of reinforcing bars, and the pressing plate 44 can press and fix the straight reinforcing bars 13 and the bent reinforcing bars 14 in the vertical direction, further increasing the stability during welding, avoiding the reinforcing bars from warping due to stress, and ensuring the welding quality.

[0058] When the welding of the first side is completed, turn over the straight steel bar 13 and the bent steel bar 14, and then the vertical slider 23 drives the bearing seat 30 to descend, and the height of the bearing seat 30 at the rear side is lower than that of the bearing seat 30 at the front side. Then, the horizontal slider 21 drives the bearing seats 30 on both the front and rear sides to swap positions. That is, since the bent steel bar 14 is in a Z shape, the welding positions of the two horizontal parts on the straight steel bar 13 are different. After the bearing seats 30 on the front and rear sides swap positions, it can just adapt to the welding positions on the straight steel bar 13 and the bent steel bar 14 after turning over, without the need to rotate the straight steel bar 13 and the bent steel bar 14 again, saving manpower.

[0059] It should be emphasized that, due to the misaligned arrangement of the two positioning components in the front-back direction, in order to enable the two positioning components on the front and rear sides to still correspond to the fixing holes 11 after swapping positions, in this embodiment, the widths of the two mutually misaligned fixing holes 11 in the front and back directions are both increased (as Figure 10 shown), so that one fixing hole 11 can accommodate two positioning components. That is, when the positioning component at the rear side moves to the front side, the corresponding fixing hole 11 at the front side can also match it.

[0060] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
