Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for welding steel cages, and in particular to an auxiliary tool for welding steel cages. Background Technology

[0002] Welding of reinforcing cages is a crucial process in construction engineering, and its quality directly affects the structural safety and durability. Its main function is similar to that of longitudinal reinforcement in columns, primarily acting as a tensile force. Concrete has high compressive strength but very low tensile strength, thus it acts as a constraint on the concrete of the pile body, enabling it to withstand a certain axial tensile force. It includes longitudinal and ring reinforcement. Multiple longitudinal reinforcements arranged in a ring array need to be welded to the ring reinforcement at their contact points to form a column-shaped reinforcing cage. In the construction of roads, bridges, or high-rise buildings, foundation piling may be required depending on the requirements. This is done by using machine punching and water-jet drilling to achieve the designed depth, then lowering the reinforcing cage into the pile hole, and finally inserting a guide pipe for concrete pouring.

[0003] Existing patent (publication number CN212191878U) discloses "This utility model discloses an auxiliary tool for welding reinforced steel cages for bridge casting, mainly relating to the field of reinforced steel cage welding and forming technology. It includes a fixed support assembly, a sliding support assembly, and an adjusting device; both the fixed support assembly and the sliding support assembly include a ring frame, a central shaft, and a support frame; the ring frame has a ring array of longitudinal reinforcement support rods; the longitudinal reinforcement support rods have through holes; the support frame of the fixed support assembly is fixed to the ground; the sliding support assembly has sliders at both ends of the support frame; the adjusting device includes a slide rail, a servo motor, and a screw and nut transmission mechanism; the sliders are slidably connected to the slide rail; the screw and nut transmission mechanism includes a transmission screw and a driven nut. The beneficial effects of this utility model are: it can support the longitudinal and ring reinforcements of the reinforced steel cage without manual support, requiring only welding workers to complete the welding work, reducing coordination requirements and labor costs, and greatly improving welding efficiency."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: Most existing auxiliary tools for welding steel cages are made by installing multiple longitudinal bars into the holes on the support rods of the longitudinal bars on both sides, and then fitting the ring bars into the corresponding welding positions on the outside of the longitudinal bars arranged in a ring array. Then, by activating multiple sets of tensioning cylinders, the piston rods are extended, pushing the longitudinal bars to expand outward in the radial direction, so that the longitudinal bars and the inner surfaces of the ring bars are tightly fitted before welding. The use of multiple sets of tensioning cylinders leads to a complex overall structure, and the multiple sets of cylinders and supporting pipelines increase manufacturing costs and maintenance difficulties.

[0005] Therefore, those skilled in the art have provided an auxiliary tool for welding steel cages to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a welding auxiliary tool for steel cages. By adjusting the cooperation between the turntable and the support block in the adjustment mechanism, the position of the support block can be flexibly adjusted to adapt to steel cages of different diameters. This not only enhances the versatility of the equipment and meets the welding needs of steel cages of different specifications in various road and bridge projects, but also reduces the cost incurred by construction units due to the need to replace auxiliary tools of different specifications.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A welding auxiliary tool for steel cages includes a fixed plate, two mounting seats and a movable plate. The upper ends of the fixed plate and the movable plate are provided with adjustment mechanisms. The two adjustment mechanisms include fixed frames. Turntables are rotatably provided at opposite ends inside the two fixed frames. Multiple support blocks are threadedly provided at opposite ends of the two turntables.

[0009] The rear end of the fixed plate is fixedly equipped with a multi-stage electric telescopic rod.

[0010] Furthermore, each of the multiple support blocks has a through hole at its front end, and each of the multiple support blocks has a scale line fixedly installed on one side.

[0011] Furthermore, each of the two turntables has a rotating ring fixedly installed at opposite ends, and the two rotating rings are rotatably mounted on opposite ends of the two fixed frames.

[0012] Furthermore, multiple limiting grooves are provided on the outer surfaces of both fixing frames, and multiple supporting blocks are slidably disposed inside the multiple limiting grooves.

[0013] Furthermore, the lower ends of the two fixed frames are respectively fixedly mounted on the upper ends of the fixed plate and the movable plate, and the exterior of the plurality of support blocks are slidably mounted inside the two fixed frames.

[0014] Furthermore, the output end of the multi-stage electric telescopic rod is fixedly installed at the front end of the movable plate, and anti-slip textures are provided on the outside of both rotating rings.

[0015] Furthermore, guide rods are bolted between the two mounting bases, and the lower ends of both the fixed plate and the movable plate are slidably disposed outside the two guide rods.

[0016] This utility model has the following beneficial effects:

[0017] This utility model proposes a welding auxiliary tool for steel cages. In use, a multi-stage electric telescopic rod pushes the movable plate to a suitable position. Then, the longitudinal reinforcement bars can be inserted into the through holes. Next, the ring reinforcement bars are placed on the outer surface of the longitudinal reinforcement bars. Then, the longitudinal reinforcement bars are inserted into the through holes on the movable plate. Subsequently, the rotating ring is rotated, causing the turntable to rotate inside the fixed frame. This causes the support block to drive the longitudinal reinforcement bars to expand outward through the through holes, so that the outer surface of the longitudinal reinforcement bars contacts and tightens with the inner surface of the ring reinforcement bars. Then, the contact point between the two can be welded. The overall manufacturing cost is low, and the maintenance is simple. It is suitable for widespread application in various road and bridge construction sites. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 One embodiment provided by this utility model:

[0027] A welding auxiliary tool for steel cages includes a fixed plate 1, two mounting bases 2 and a movable plate 5. The upper ends of the fixed plate 1 and the movable plate 5 are provided with adjustment mechanisms 6. The two adjustment mechanisms 6 include fixed frames 602. Turntables 606 are rotatably provided at opposite ends of the two fixed frames 602. Multiple support blocks 601 are threadedly provided at opposite ends of the two turntables 606.

[0028] Multiple support blocks 601 are provided with through holes 605 at their front ends. Scale lines 604 are fixedly provided on one side of each support block 601. Rotating rings 603 are fixedly provided at opposite ends of each of the two turntables 606. The two rotating rings 603 are rotatably mounted on opposite ends of each of the two fixed frames 602. Multiple limiting grooves 607 are provided on the outer surface of each of the two fixed frames 602. The multiple support blocks 601 are slidably mounted inside the multiple limiting grooves 607. The lower ends of the two fixed frames 602 are respectively fixedly mounted on the upper ends of the fixed plate 1 and the movable plate 5. The multiple support blocks 601 are slidably mounted inside the two fixed frames 602. Anti-slip textures are provided on the outer surfaces of the two rotating rings 603.

[0029] Specifically, when precisely fitting the steel cage to be welded according to its design diameter using the adjustment mechanism 6, the operator holds the rotating ring 603 and uses the stable friction provided by the anti-slip texture to drive the rotating ring 603 to rotate the turntable 606. Due to the threaded transmission between the turntable 606 and the support block 601, and the fact that the thread on the turntable 606 is a planar thread, the support block 601 can slide linearly along the limiting groove 607 inside the fixing frame 602 during the rotation of the turntable 606. The limiting groove 607 can play a guiding role. During the adjustment process, the scale line 604 on the side of the support block 601 provides the operator with a precise reference, ensuring that the spacing of the support blocks 601 can be flexibly adjusted according to the diameter of the steel cage. This allows the support blocks 601 to drive the longitudinal bars in the perforation 605 to expand outward, so that their outer surface is in close contact with the inner surface of the ring bar and is tightened and fixed. Thus, the contact point between the longitudinal bar and the ring bar can be welded efficiently. The entire operation process is smooth and efficient, improving construction efficiency and reducing the welding defect rate.

[0030] The adjustment mechanism 6, through the combination of threaded transmission and limit guidance, achieves rapid adaptation to steel cages of different diameters. The scale line 604 on the support block 601 provides a quantitative standard for steel bar positioning. Combined with the precise fixing effect of the through hole 605, it ensures that the installation position error of the longitudinal bars and ring bars is minimal. At the same time, the guide rod 3 provides stable guidance to the movable plate 5, avoiding positional deviations during the spacing adjustment process. It ensures the manufacturing accuracy of the steel cage from both diameter and length dimensions, reduces the welding defect rate, and lays a solid foundation for the structural safety of road and bridge engineering. Compared with traditional fixed-size auxiliary tools, this tool enhances the versatility of the equipment, can meet the welding needs of steel cages of different specifications in various road and bridge engineering projects, reduces the cost of construction units due to the replacement of auxiliary tools of different specifications, facilitates subsequent maintenance, and the overall adjustment process does not require multiple pneumatic systems, which can reduce the overall manufacturing cost. The longitudinal bars are longitudinal steel bars, and the ring bars are ring steel bars. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Reference Figures 1-3 A multi-stage electric telescopic rod 4 is fixedly installed at the rear end of the fixed plate 1. The output end of the multi-stage electric telescopic rod 4 is fixedly installed at the front end of the movable plate 5. Guide rods 3 are fixed between the two mounting seats 2 by bolts. The lower ends of the fixed plate 1 and the movable plate 5 are slidably installed outside the two guide rods 3.

[0032] Specifically, when using this rebar cage welding auxiliary tool, it is first securely installed in a suitable position on the construction site using the mounting base 2. Then, the multi-stage electric telescopic rod 4 is activated. This is a mature and publicly available technology, so its specific structure and working principle will not be elaborated upon in this article. The output end of the multi-stage electric telescopic rod 4 pushes the movable plate 5, causing it to slide smoothly along the guide rod 3. The guide rod 3, with its precise limiting and guiding function, effectively prevents the movable plate 5 from shifting, ensuring the stability and safety of the movement process. The multi-stage electric telescopic rod 4 and the guide rod 3 can flexibly adjust the equipment spacing to adapt to different length requirements, improving the versatility of the auxiliary tool and enabling the equipment to meet the welding operations of various specifications of rebar cages, effectively reducing the equipment procurement and maintenance costs for construction units.

[0033] Working principle: When it is necessary to adjust the distance between the fixed plate 1 and the movable plate 5 to accommodate the welding requirements of steel cages of different lengths, the multi-stage electric telescopic rod 4 is activated. The output end of the multi-stage electric telescopic rod 4 pushes the movable plate 5, causing the lower end of the movable plate 5 to slide along the outside of the guide rod 3. The guide rod 3 plays a limiting and guiding role, ensuring that the movable plate 5 will not deviate during movement and slides smoothly along the guide rod 3. When the movable plate 5 slides to a certain position, the longitudinal reinforcement passes through the support block 60 in the fixed plate 1. The perforation 605 on the fixed plate 1 is then made. The ring reinforcement is then fitted onto the outer surface of the multiple longitudinal reinforcements. The longitudinal reinforcement is then passed through the perforation 605 on the support block 601 in the movable plate 5. The position of the ring reinforcement on the outer surface of the longitudinal reinforcement is then adjusted. Then, the rotating ring 603 is rotated so that the turntable 606 rotates inside the fixed plate 1, causing the support block 601 to drive the longitudinal reinforcement to expand outward, so that the outer surface of the longitudinal reinforcement contacts and tightens with the inner surface of the ring reinforcement. The scale line 604 is convenient for the operator to adjust. At this time, the contact points of multiple longitudinal reinforcements and ring reinforcements can be welded.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
