Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a welding device for steel cages used in building construction. Background Technology

[0002] In the construction of urban rail transit, the integrated construction of new hubs and the renovation of existing subway stations is a crucial link. Among the many engineering stages involved in the integrated construction, the steel cage, as a basic structural component, is widely used in station foundation construction, underground continuous walls, and other parts. Its quality plays a decisive role in the safety and stability of the entire project. The steel cage is mainly composed of longitudinal bars, positioning hoops, and stirrups. The longitudinal bars are the main load-bearing components of the steel cage, bearing the tensile and compressive forces of the structure. The positioning hoops are used to fix the position of the longitudinal bars and ensure the overall shape of the steel cage is regular. The stirrups are responsible for connecting the longitudinal bars and enhancing the overall rigidity and stability of the steel cage. In the operation of welding the stirrups to the steel cage, the longitudinal bars are usually first welded and fixed to the positioning hoops according to the design spacing to form the prototype of the steel cage. Then, the stirrups are wound around the outside of the longitudinal bars according to the preset pitch, and then welded to make the stirrups and longitudinal bars tightly connected, finally completing the fabrication of the steel cage and providing a stable steel skeleton support for subsequent concrete pouring.

[0003] However, the existing technology has the following problems: In existing technologies, when welding steel reinforcement cages, specialized welding tools are required to position and reinforce the cages before subsequent welding operations can be carried out. However, in actual construction, steel reinforcement cages come in a variety of specifications, and cages with different diameters and longitudinal reinforcement arrangements require corresponding specialized tools. This not only significantly increases equipment procurement costs and adds to the economic burden on the construction party, but also causes a waste of site resources due to the storage of a large number of tools, which also brings many inconveniences to on-site material management. Summary of the Invention

[0004] The purpose of this invention is to provide a steel cage welding device for building construction in order to solve the above-mentioned problems. It aims to overcome the shortcomings of existing steel cage welding, which requires the preparation of multiple special tools to adapt to steel cages of different specifications, which increases equipment costs and occupies space, resulting in waste. Details are described below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a welding device for steel cages used in building construction, comprising: a supporting rotation assembly, which includes a main shaft and four support plates, the four support plates supporting the inner wall of the steel cage from the inside out, and the main shaft driving the steel cage to rotate via the four support plates; a welding assembly capable of welding the rotating steel cage during movement; an auxiliary feeding assembly including multiple pulleys for rolling and conveying the steel cage; an adjusting part for adjusting the support diameter of the four support plates; and a positioning hoop support part for supporting two positioning hoops of the steel cage.

[0006] Preferably, the supporting rotation assembly includes a drive box and a column. A support arm is hinged to the column, and a first hydraulic cylinder is hinged between the support arm and the column. One end of the main shaft is connected to the drive box, and the other end of the main shaft rests on the support arm. A roller is provided at the contact position between the support arm and the main shaft. Multiple mounting rings are connected to the main shaft. Multiple first connecting rods are hinged to the support plate, and the multiple first connecting rods on the support plate are respectively hinged to the multiple mounting rings. The four support plates are arranged in a circular array with the main shaft as the center.

[0007] Preferably, the adjusting part includes a second hydraulic cylinder and four slide rods. The second hydraulic cylinder is mounted on the drive box. The output end of the second hydraulic cylinder is connected to a fixed ring. The inner wall of the fixed ring is rotatably connected to a rotating ring. The four slide rods are all slidably connected to the main shaft. The ends of the four slide rods near the drive box are all connected to the rotating ring. Multiple second connecting rods are hinged on the slide rods. The multiple second connecting rods on the slide rods are respectively hinged to multiple first connecting rods on the support plate.

[0008] Preferably, the positioning hoop support includes four arc-shaped panels and four grooved plates. The four arc-shaped panels are respectively connected to the side of the four support plates away from the main shaft. Slide plates are slidably connected to both ends of the arc-shaped panels. Connecting plates are respectively connected to the side of the two slide plates near the main shaft. Sliding shafts are respectively connected to the two connecting plates. The four grooved plates are slidably connected to the side of the four support plates near the main shaft. Two inclined sliding grooves are provided on the grooved plates. The two sliding shafts are slidably connected to the two inclined sliding grooves of the grooved plates. Third connecting rods are respectively hinged to the four grooved plates. The four third connecting rods are respectively hinged to the four first connecting rods on one of the fixed rings.

[0009] Preferably, there are two positioning hoop supports, which are located near the two ends of the four support plates.

[0010] Preferably, the welding assembly includes a ground rail, a slide block slidably connected to the ground rail, a ball screw rotatably mounted on the ground rail, a motor mounted on the ground rail, the output end of the motor connected to the ball screw, the slide block and the ball screw connected by a ball thread, a control cabinet connected to the slide block, two cylinders connected to the control cabinet, the output ends of the two cylinders connected to a mounting base, a linear module mounted on the mounting base, and a welding torch connected to the linear module.

[0011] Preferably, two guide wheels are rotatably mounted on the mounting base, and the welding torch is located between the two guide wheels.

[0012] Preferably, the supporting rotation assembly further includes a side protrusion, which includes four protruding plates. The four protruding plates are slidably connected to four support plates, and multiple springs are connected between the protruding plates and the support plates. A rotating shaft is rotatably connected through the support plates, and a cam is connected to the rotating shaft. The cam is located between the protruding plates and the support plates. A lever is connected to one end of the rotating shaft near the fixed ring, and an arc-shaped rod is connected to the side of the fixed ring near the welding assembly. The arc-shaped rod is located on the movement trajectory of the lever, and when the lever contacts the arc-shaped rod, it drives the rotating shaft to rotate.

[0013] Preferably, the auxiliary feeding assembly includes a platform, on which a mounting frame is vertically slidably connected, and multiple pulleys are rotatably mounted on the mounting frame.

[0014] Preferably, the bottom of the mounting bracket is connected to a first inclined block, and the base is connected to a second inclined block. The first inclined block and the second inclined block are in sliding contact. A connecting arm is connected to the second inclined block, and the end of the connecting arm away from the second inclined block is connected to a fixing ring.

[0015] The beneficial effects are: 1. This steel cage welding device for building construction, through the cooperation of the supporting rotating component and the adjusting part, enables the sliding rod to move to the left by activating the second hydraulic cylinder. The second and first connecting rods then move the four support plates away from the main axis, supporting and fixing steel cages of various specifications. This achieves the technical effect of adapting to various steel cage specifications, eliminating the need for custom welding fixtures and saving construction space. The positioning hoop support part allows the four arc-shaped panels to expand outwards as the four support plates move away from the main axis. Simultaneously, the sliding plates at both ends of the arc-shaped panels extend outwards, filling the expanded gaps between the arc-shaped panels. This increases the contact area with the positioning hoop and prevents local deformation of the positioning hoop.

[0016] 2. The steel cage welding device for building construction, through the setting of welding components, enables the motor to drive the ball screw to rotate, thereby driving the slide and control cabinet to move. The control cabinet controls the motor, two cylinders, linear module and welding gun to carry out automated welding operations, realizing the synchronous operation of stirrup winding and welding, and achieving the technical effect of improving work efficiency.

[0017] 3. The steel cage welding device for building construction, through the setting of the side protrusion, allows the lever to contact the arc-shaped rod after the support plate enters the welding area, driving the cam to rotate and lift the protrusion plate, so that the longitudinal reinforcement in this area is pushed outward, ensuring effective contact between the longitudinal reinforcement and the stirrups. This achieves the technical effect of avoiding the inward bending of some middle sections of the longitudinal reinforcement, which would cause it to detach from the stirrups, and improving the welding quality.

[0018] 4. The steel cage welding device for building construction, through the setting of auxiliary feeding components, allows the bottom of the steel cage to be placed on multiple pulleys during hoisting. The steel cage slides along the pulleys, and at the same time, when the four support plates are opened, the fixing ring drives the second inclined block to move to the left, so that the installation frame and pulleys move down and disengage from the steel cage. This achieves the technical effect of improving the stability of the steel cage movement and reducing wear on the support plates. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] Example 1 In existing steel cage welding, multiple longitudinal bars need to be welded and fixed to two positioning hoops to form the basic shape of the steel cage. Then, welding fixtures are used to fix the steel cage before welding. However, since the construction site requires steel cages of various specifications, and each specification of steel cage needs to be equipped with matching welding fixtures, the equipment cost is increased. In addition, placing multiple welding fixtures also causes a waste of space. To solve the above problems, this embodiment is invented.

[0024] Please see Figure 1 - Figure 4A welding device for steel cages used in building construction includes: a support and rotation assembly 1, which includes a main shaft 12 and four support plates 15. The four support plates 15 support the inner wall of the steel cage from the inside to the outside. The main shaft 12 drives the steel cage to rotate through the four support plates 15. The support and rotation assembly 1 includes a drive box 11 and a column 16. A support arm 17 is hinged to the column 16. A first hydraulic cylinder 18 is hinged between the support arm 17 and the column 16. One end of the main shaft 12 is connected to the drive box 11, and the other end of the main shaft 12 rests on the support arm 17. The contact position between the support arm 17 and the main shaft 12 is... The device is equipped with rollers, and multiple mounting rings 13 are connected to the main shaft 12. Multiple first connecting rods 14 are hinged to the support plate 15. The multiple first connecting rods 14 on the support plate 15 are respectively hinged to the multiple mounting rings 13. The four support plates 15 are arranged in a circular array with the main shaft 12 as the center. When installing the steel cage, the first hydraulic cylinder 18 is driven to move the support arm 17 downward, so that the support arm 17 is separated from the main shaft 12. At this time, the steel cage is put on the four support plates 15 from left to right. Then, the first hydraulic cylinder 18 is driven to move the support arm 17 upward and reset, so that the support arm 17 abuts against the main shaft 12 again. At this time, the initial installation of the steel cage is completed.

[0025] Furthermore, please refer to Figure 1 - Figure 4The supporting rotating assembly 1 includes an adjusting part 2, which is used to adjust the supporting diameter of the four support plates 15. The adjusting part 2 includes a second hydraulic cylinder 21 and four sliding rods 24. The second hydraulic cylinder 21 is mounted on the drive box 11. The output end of the second hydraulic cylinder 21 is connected to a fixed ring 22. The inner wall of the fixed ring 22 is rotatably connected to a rotating ring 23. The four sliding rods 24 are all slidably connected to the main shaft 12. The end of each of the four sliding rods 24 near the drive box 11 is connected to the rotating ring 23. Multiple second connecting rods 25 are hinged on the sliding rods 24. The multiple second connecting rods 25 on the sliding rods 24 are respectively connected to multiple first connecting rods on the support plates 15. The rod 14 is hinged, driving the second hydraulic cylinder 21, which in turn moves the fixed ring 22 to the left. When the fixed ring 22 moves to the left, it drives the four sliding rods 24 to the left via the rotating ring 23. When the sliding rods 24 move to the left, they can use multiple second connecting rods 25 to drive multiple first connecting rods 14 to swing away from the main shaft 12. Considering the multiple first connecting rods 14 on the support plate 15 as a group, when the four groups of first connecting rods 14 swing away from the main shaft 12, they can drive the four support plates 15 to move away from the main shaft 12. During the initial installation of the reinforcing cage, there is a certain gap between the reinforcing cage and the four support plates 15, while the four support plates 15... When the cylinder moves away from the main shaft 12, it can contact the inner wall of the rebar cage and support and fix the rebar cage from the inside out. When the four support plates 15 apply a certain pressure to the rebar cage, the second hydraulic cylinder 21 detects the preset pressure through the pressure sensing element. The control system cuts off the oil supply and maintains the oil circuit pressure to achieve pressure holding. At this time, the rebar cage is supported and fixed. The four support plates 15 have a certain range of support diameter, so they can be adapted to various rebar cages of different specifications. This achieves the technical effect of supporting and fixing rebar cages of various specifications by starting the second hydraulic cylinder 21, which is relatively convenient to operate. This eliminates the cost of customizing multiple welding fixtures and saves construction space. After the steel cage is stabilized, the drive box 11 is started, which drives the main shaft 12 to rotate. The main shaft 12 drives the four support plates 15 to rotate through multiple mounting rings 13 and four sets of first connecting rods 14. The four support plates 15 drive the steel cage to rotate. At this time, the external stirrup unwinding device and supporting equipment are used to wind the stirrups onto the steel cage. The external stirrup unwinding device and supporting equipment are existing technology equipment commonly used in steel cage preparation. They can use the rotation of the steel cage to wind the stirrups onto the steel cage. Their specific structure and working principle will not be described in detail here.

[0026] In addition, please see Figure 1 , Figure 5 , Figure 6The rotating support assembly 1 also includes a positioning hoop support 3 for supporting two positioning hoops of the reinforcing cage. The positioning hoop support 3 includes four arc-shaped panels 31 and four grooved plates 35. The four arc-shaped panels 31 are respectively connected to the side of the four support plates 15 away from the main shaft 12. Slide plates 32 are slidably connected to both ends of the arc-shaped panels 31. Connecting plates 33 are respectively connected to the side of the two slide plates 32 near the main shaft 12. Sliding shafts 34 are respectively connected to the two connecting plates 33. The four grooved plates 35 are slidably connected to the side of the four support plates 15 near the main shaft 12. Two inclined sliding grooves are provided on the grooved plates 35. The two sliding shafts 34 are slidably connected to the two inclined sliding grooves of the grooved plates 35 respectively. Third connecting rods 36 are respectively hinged to the four grooved plates 35. The four third connecting rods 36 are respectively connected to one of the fixing rings 22. The four first connecting rods 14 are hinged. Two positioning hoop support parts 3 are provided, located near the ends of the four support plates 15. During the installation of the reinforcing cage, the two positioning hoops are kept on the two positioning hoop support parts 3. Taking one positioning hoop support part 3 as an example, the four arc-shaped panels 31 form a near-circular shape, supporting and fixing the positioning hoop. Compared to the four support plates 15, the four arc-shaped panels 31 have a larger contact area with the positioning hoop, thus providing more stable support and preventing local deformation of the reinforcing cage caused by local deformation of the positioning hoop. When the four support plates 15 move away from the main axis 12, the gap between the four arc-shaped panels 31 also increases. Meanwhile, taking one arc-shaped panel 31 as an example, refer to... Figure 6 As the first link 14 moves the support plate 15 away from the main shaft 12, the angle between the first link 14 and the support plate 15 increases. This causes the first link 14 to pull the groove plate 35 towards the third link 36 via the third link 36. When the groove plate 35 moves, it drives the two sliding shafts 34 away from the third link 36 via the two inclined sliding grooves. This causes the two sliding shafts 34 to drive the two sliding plates 32 to extend outward from both ends of the arc panel 31 via the two connecting plates 33. Therefore, when the four arc panels 31 expand outward, the sliding plates 32 at both ends of each arc panel 31 also extend outward synchronously. This allows the sliding plates 32 between two adjacent arc panels 31 to fill the expanded gap between the arc panels 31, thereby maximizing the contact area with the positioning hoop and preventing the positioning hoop from being ineffectively supported and causing local deformation.

[0027] It is worth noting that, please refer to Figure 1 , Figure 7 , Figure 8Welding assembly 5, capable of welding a rotating steel cage during movement; welding assembly 5 includes a ground rail 51, a slide block 52 slidably connected to the ground rail 51, a ball screw 53 rotatably mounted on the ground rail 51, a motor 54 mounted on the ground rail 51, the output end of the motor 54 connected to the ball screw 53, the slide block 52 and the ball screw 53 connected via ball threads, a control cabinet 55 connected to the slide block 52, two cylinders 56 connected to the control cabinet 55, the output ends of the two cylinders 56 connected to a mounting base 57, a linear module 58 mounted on the mounting base 57, and a welding torch 59 connected to the linear module 58; after the motor 54 starts, it can drive the ball screw 53 to rotate, and when the ball screw 53 rotates, it drives the slide block 52 to move left or right on the ground rail 51 through the balls. The control cabinet 55 moves left or right, and the two cylinders 56 adjust the position of the mounting base 57, allowing the welding torch 59 to move within the working range. The linear module 58 can drive the welding torch 59 to move back and forth and up and down. The control cabinet 55 controls the motor 54, the two cylinders 56, the linear module 58, and the welding torch 59 to carry out automated welding operations. The control cabinet 55, the linear module 58, and the welding torch 59 are all existing technologies, and their specific structures and working principles will not be elaborated. The stirrups start to be wound from right to left. As the steel cage rotates, the welding torch 59 moves freely and slowly to the left, following the progress of the stirrup winding to perform welding, thereby synchronizing the stirrup winding and the stirrup welding, improving work efficiency. The motor 54 can adjust its speed according to the stirrup spacing and the stirrup winding rate to ensure that the movement of the welding torch 59 matches the stirrup winding operation.

[0028] It is worth noting that, please refer to Figure 7 Two guide wheels 510 are rotatably mounted on the mounting base 57. The welding torch 59 is located between the two guide wheels 510. When the two cylinders 56 drive the mounting base 57 closer to the reinforcing cage, the two guide wheels 510 abut against the outer wall of the reinforcing cage. After the cylinders 56 sense the resistance, they enter the pressure holding state, so that the welding torch 59 can always maintain a reasonable distance from the welding work surface. This avoids the cylinders 56 extending too much when adjusting the distance of the mounting base 57, which would cause the welding torch 59 to get stuck in the longitudinal reinforcement. At the same time as welding, the two guide wheels 510 continuously press the stirrups to prevent the stirrups in the welding area from bulging and losing contact with the longitudinal reinforcement.

[0029] Example 2 Based on Example 1, since the longitudinal bars are slightly bent, the middle section of some longitudinal bars may bend inward during welding, resulting in gaps between the longitudinal bars and stirrups during welding, which affects the welding quality. This example is invented to solve the above problem.

[0030] Please see Figure 1 , Figure 7 , Figure 9 , Figure 10The supporting rotating assembly 1 also includes a side protrusion 4, which includes four protruding plates 41. The four protruding plates 41 are slidably connected to four support plates 15. Multiple springs 45 are connected between the protruding plates 41 and the support plates 15. A rotating shaft 42 is rotatably connected through the support plates 15. A cam 44 is connected to the rotating shaft 42 and is located between the protruding plates 41 and the support plates 15. A lever 43 is connected to one end of the rotating shaft 42 near the fixed ring 22. An arc-shaped rod 46 is connected to one side of the fixed ring 22 near the welding assembly 5. The arc-shaped rod 46 is located on the movement trajectory of the lever 43. When lever 43 contacts arc-shaped rod 46, it drives shaft 42 to rotate. Taking one of the protruding plates 41 as an example, when protruding plate 41 and support plate 15 are about to move into the welding area, lever 43 contacts arc-shaped rod 46. Lever 43 is pushed by the reaction force of arc-shaped rod 46 and swings. When lever 43 swings, it drives cam 44 to rotate through shaft 42. When cam 44 rotates, it can lift protruding plate 41, making protruding plate 41 protrude from the surface of support plate 15. After protruding plate 41 leaves the welding area, the welding area has a margin larger than the actual welding range, and lever 43 disengages. The multiple springs 45 between the convex plate 41 and the support plate 15, separated from the arc-shaped rod 46, cause the convex plate 41 to reset via elastic force. When the convex plate 41 resets, it presses the cam 44, causing the cam 44, the rotating shaft 42, and the lever 43 to reset together. The length of the lever 43 is greater than the movable distance of the support plate 15. Therefore, after the support plate 15 adjusts its support diameter, the lever 43 can always contact the arc-shaped rod 46 during movement. The cam 44 has a certain elasticity. When the convex plate 41 is subjected to the counter-thrust of the reinforcing cage, it will stop protruding. At this time, the convex plate 41 applies pressure to the cam 44. The deformation of plate 44 causes the convex plate 41 to apply only reasonable pressure to the reinforcing cage, avoiding excessive lifting of the reinforcing cage by the convex plate 41. Therefore, after the support plate 15 enters the welding area, the convex plate 41 can convex outward, causing the longitudinal bars in this area to be pushed outward. Due to the influence of the positioning hoop and the already welded hoop, the longitudinal bars in the area near the convex plate 41 will also be pulled outward, so that the longitudinal bars within the actual welding range will be pushed outward, thereby ensuring that the longitudinal bars are in effective contact with the hoop during welding, and avoiding the middle section of some longitudinal bars bending inward and causing them to detach from the hoop.

[0031] Example 3 Based on Embodiment 1, when installing the reinforcing cage, hoisting equipment is required. However, the reinforcing cage is prone to shaking during hoisting. As the reinforcing cage is placed on the four support plates 15, it is easy to hit the support plates 15 due to shaking. When the reinforcing cage moves, it will also cause wear and tear on the support plates 15. After long-term use, the support plates 15 are prone to damage. In order to solve the above problems, this embodiment is invented.

[0032] Please see Figure 1 , Figure 11 , Figure 12The auxiliary feeding assembly 6 includes multiple pulleys 63 for rolling and transferring the rebar cage. The auxiliary feeding assembly 6 includes a platform 61, on which a mounting frame 62 is vertically slidably connected. The multiple pulleys 63 are rotatably mounted on the mounting frame 62. A first inclined block 64 is connected to the bottom of the mounting frame 62, and a second inclined block 65 is connected inside the platform 61. The first inclined block 64 and the second inclined block 65 are in slidable contact. A connecting arm 66 is connected to the second inclined block 65, with one end of the connecting arm 66 away from the second inclined block 65 connected to a fixing ring 22. The multiple pulleys 63 are located below four support plates 15. When hoisting the rebar cage, the bottom of the rebar cage is placed on the multiple pulleys 63, allowing the pulleys 63 to provide support. This then moves the rebar cage to the right, sliding along the multiple pulleys 63, improving the stability of the rebar cage during movement and reducing its sway. To minimize wear on the support plate 15, since the inclined surface of the second inclined block 65 is in contact with the inclined surface of the first inclined block 64, and the platform 61 limits the mounting frame 62, the mounting frame 62 can only slide up and down. Therefore, when the second inclined block 65 moves to the right, it can push the mounting frame 62 upward through the first inclined block 64. The mounting frame 62 drives multiple pulleys 63 to move upward. When the second inclined block 65 moves to the left, the mounting frame 62 and the first inclined block 64 slide down by their own weight, so that the first inclined block 64 always fits against the second inclined block 65. Therefore, when the four support plates 15 are opened, the fixing ring 22 moves to the left and drives the connecting arm 66 to move to the left. The connecting arm 66 drives the second inclined block 65 to move to the left, and the mounting frame 62 and multiple pulleys 63 move downward. After the steel cage is supported and fixed by the four support plates 15, the multiple pulleys 63 can directly disengage from the steel cage, avoiding affecting the rotation of the steel cage and welding operations.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
