Description

Technical Field

[0001] This invention belongs to the field of steel cage welding technology, and particularly relates to a steel cage welding device for internal bracing of concrete utility poles. Background Technology

[0002] In the current power grid construction process, concrete poles are generally used for support. In order to improve load-bearing capacity and stability, a steel cage is added to the concrete as an internal support for the pole. The steel cage is generally composed of main bars and stirrups surrounding its outer wall. The main bars and stirrups are welded together by welding methods such as arc welding. The stirrups can improve the pole's seismic resistance, so that even if it cracks, it will not fail instantly.

[0003] During the welding process of the rebar cage, since the main reinforcement used in the pole is not the large-diameter steel bar used in the beams and columns of the building industry, the stirrups will have a certain restraining effect on the main reinforcement when they are wrapped around the outer wall of the main reinforcement. This can easily lead to excessive stress on the main reinforcement and deformation, which in turn affects the strength of the rebar cage. Furthermore, since the pole is generally tapered, its diameter needs to be gradually reduced during processing. However, existing equipment is difficult to achieve this dynamic and high-precision diameter adjustment during welding and cannot guarantee that the local diameter of the rebar cage is perfectly matched with the standard taper. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the main reinforcement is easily deformed due to the binding effect of the stirrups on the main reinforcement during the winding process, and to propose a steel cage welding device for the internal support of concrete poles.

A connecting groove is installed inside the support rod, and the connecting groove and the support rod are placed crosswise. The second cantilever rod is slidably connected to the connecting groove through a connecting post at one end.

[0008] As a further description of the above technical solution: It also includes: an adjustment assembly, the adjustment assembly including a mounting ring installed inside the mounting base and the mounting ring being located on one side of the support frame, and an extrusion strip being installed inside the mounting ring; A fixing plate is installed at one end of the connecting cylinder, and a threaded rod is installed on one side of the fixing plate.

[0009] As a further description of the above technical solution: The adjustment assembly further includes: a fixing frame, which is installed on one side of the support frame, and a threaded cylinder is rotatably installed on the fixing frame through an internal through hole, and the threaded cylinder is threadedly connected to the threaded rod; The toothed plate is embedded in the through hole inside the mounting ring and is fixed to the mounting ring by a fixing pin. A bevel gear is mounted on one end of a threaded cylinder and meshes with a toothed plate. The bevel gear has a through hole inside that corresponds to the threaded rod.

[0010] As a further description of the above technical solution: The adjustment assembly further includes a friction block, which is slidably mounted on one side of the fixed frame, and the bottom end of the friction block is in contact with the outer wall of the threaded cylinder; The extrusion block is slidably disposed on one side of the fixed frame, and one end of the extrusion block is provided with an inclined surface corresponding to one end of the friction block, and the other end of the extrusion block is provided with an arc surface corresponding to the extrusion strip.

[0011] As a further description of the above technical solution: It also includes: a guide assembly, the guide assembly comprising a fixed base mounted on one side of the mounting base, and a shaping wheel assembly mounted on one side of the fixed base; A rotating seat is rotatably mounted at one end of a fixed seat.

[0012] As a further description of the above technical solution: The guide assembly further includes a support bar, which is mounted on one side of the mounting base and is arc-shaped, and is located between the fixed base and the rotating base; An extrusion wheel is mounted on one side of the support bar.

[0013] As a further description of the above technical solution: The guiding assembly further includes: a second limiting wheel, which is mounted on one side of the rotating seat and corresponds to the shaping wheel assembly; The first limiting wheel is located at one end of the rotating seat, and the axis of the first limiting wheel is parallel to the side of the rotating seat.

[0014] As a further description of the above technical solution: The guide assembly further includes: an insert plate, which is slidably disposed in the groove on the top surface of the rotating seat, and one end of the insert plate is inserted into a through hole on one side of the support bar, and the support bar has multiple through holes on one side. The second spring is installed at the other end of the insert plate, and the other end of the second spring is fixedly connected to the rotating seat.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, by incorporating a support component, the main reinforcement is supported by a connecting cylinder and a support wheel when the stirrups are wrapped around the outer wall of the main reinforcement. This prevents deformation of the main reinforcement due to excessive tightening force of the stirrups during the winding process, ensuring overall support strength. Furthermore, the position of the support wheel can be dynamically changed by moving the connecting cylinder, utilizing the connection between the second cantilever and the connecting groove. This dynamically alters the outward tilt angle of the support wheel, ensuring it maintains effective contact with the inner side of the main reinforcement throughout its continuous contraction stroke. This ensures that the support wheel continues to provide good support as the connecting cylinder contracts. Simultaneously, the contraction of the connecting cylinder allows for a gradual reduction in the diameter of the reinforcing cage, ensuring a perfect match between the reinforcing cage and the standard taper of the utility pole.

[0016] In this invention, by incorporating an adjustment component, the design enables the main reinforcing bar to rotate during the traction frame's rotation. This rotation, in turn, drives the mounting frame and support frame, which in turn rotate the bevel gear and threaded cylinder. Upon reaching a certain position, the bevel gear rotates via a toothed plate, causing the threaded rod to move and thus the connecting cylinder. This ensures that the reinforcing cage gradually contracts as welding continues, maintaining a standard taper between the reinforcing cage and the pole. Furthermore, by replacing the toothed plate with different numbers of teeth, the diameter variation per revolution can be flexibly adjusted to meet the production requirements of poles with varying diameter ratios.

[0017] In this invention, by incorporating a guiding component, the bending curvature of the stirrup can be altered during the process of winding the stirrup around the outer wall of the main reinforcement. This is achieved by changing the angle between the rotating seat and the fixed seat, and by adjusting the bending curvature of the stirrup under the action of the extrusion wheel. This ensures that the stirrup can be wound more smoothly around the outer wall of the main reinforcement during the winding process, and reduces the stress on the stirrup after welding. It also prevents the weld from developing micro-cracks or peeling fractures due to stress release in the subsequent process, thereby effectively ensuring the long-term structural stability of the welded joint of the main stirrup of the steel cage and the overall strength of the skeleton.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10 The present invention provides a technical solution: a welding device for a steel cage for internal support of a concrete utility pole, comprising an installation rail 1, an installation seat 7 installed at one end of the installation rail 1, a movable frame 2 provided at the top of the installation rail 1, a traction frame 3 provided inside the movable frame 2, and a welding module 4 provided on one side of the installation seat 7, and further comprising: like Figure 3 , Figure 4 As shown, the support assembly 5 includes a support frame 502 disposed inside the mounting base 7, and the top of the support frame 502 is provided with a roller that contacts the inner wall of the mounting base 7. Mounting bracket 501 is installed in the middle of support bracket 502; The connecting cylinder 503 is slidably disposed in the sliding groove inside the mounting bracket 501, and multiple connecting cylinders 503 are arranged circumferentially. Support wheel 509 is provided on one side of connecting cylinder 503 and the support wheel 509 corresponds to the through hole inside connecting cylinder 503; The support assembly 5 also includes: a first cantilever 505, one end of which is slidably disposed in a groove inside the mounting bracket 501, and the first cantilever 505 is located at one end of the connecting cylinder 503; Support rod 508, one end of support rod 508 is rotatably mounted on the other end of first cantilever rod 505, and support wheel 509 is rotatably mounted on the other end of support rod 508; The support assembly 5 also includes: a second cantilever 506, one end of which is installed on one side of the connecting cylinder 503, and the outer wall of the second cantilever 506 is provided with a notch corresponding to the opening on one side of the mounting bracket 501; The first spring 504 is installed on one side of the first lifting rod 505 and is located in the internal cavity of the mounting bracket 501. The other end of the first spring 504 is fixedly connected to the mounting bracket 501. The connecting groove 507 is installed inside the support rod 508, and the connecting groove 507 and the support rod 508 are placed crosswise. The second cantilever rod 506 is slidably connected to the connecting groove 507 through a connecting post at one end. Furthermore, the welding module 4 is well-known in this technical field, so it is not described in detail here.

[0022] The specific implementation is as follows: In the production process of the steel cage, the main bar is first passed through the through hole inside the connecting cylinder 503, and one end of the main bar is fixed to the traction frame 3. The main bar can be moved by moving the moving frame 2. At the same time, the traction frame 3 can be rotated by the driving device on one side of the moving frame 2, so that the stirrup is wrapped around the outside of the main bar and welded by the welding module 4. Since the support wheel 509 is in contact with the inside of the main bar and the guide component 8 is set on one side of the mounting base 7, the main bar can be supported by the support wheel 509 and the connecting cylinder 503 during the stirrup winding process, so as to prevent the main bar from deforming due to the large tightening force of the stirrup during the stirrup winding process as production continues. Furthermore, during the production process, the movement of the connecting cylinder 503 can drive the movement of the second lifting rod 506. Since the second lifting rod 506 is connected to the connecting groove 507 through a connecting column at one end, and since the connecting groove 507 and the support rod 508 are placed crosswise, the movement of the second lifting rod 506 can squeeze the connecting groove 507 and push the support rod 508 to rotate, thereby changing the position of the support wheel 509 and forming a certain angle between the support wheel 509 and the connecting cylinder 503. At the same time, the connecting cylinder 503 gradually contracts towards the center to achieve the shrinkage of the steel cage. Furthermore, as the connecting cylinder 503 contracts, it will come into contact with the first cantilever 505 after moving a certain distance. As the connecting cylinder 503 continues to move, it can push the first cantilever 505 to move, and compress the first spring 504. At this time, the relative position between the support wheel 509 and the connecting cylinder 503 no longer changes, thereby ensuring that the entire steel cage can contract at a certain angle.

[0023] like Figure 5 , Figure 6 As shown, the adjustment component 6 includes a mounting ring 601 installed inside the mounting base 7, and the mounting ring 601 is located on one side of the support frame 502. An extrusion strip 602 is installed inside the mounting ring 601. A fixing plate 603 is installed at one end of the connecting cylinder 503, and a threaded rod 604 is installed on one side of the fixing plate 603. like Figure 8 , Figure 9 As shown, the adjustment assembly 6 also includes: a fixing frame 608, which is installed on one side of the support frame 502. The fixing frame 608 is rotatably mounted with a threaded cylinder 607 through an internal through hole, and the threaded cylinder 607 is threadedly connected to the threaded rod 604. The toothed plate 605 is embedded in the through hole inside the mounting ring 601, and the toothed plate 605 is fixed to the mounting ring 601 by a fixing pin. A bevel gear 606 is installed at one end of a threaded cylinder 607 and meshes with a toothed plate 605. The bevel gear 606 has a through hole inside that corresponds to the threaded rod 604. like Figure 7 As shown, the adjustment component 6 also includes a friction block 609, which is slidably mounted on one side of the fixed frame 608, and the bottom end of the friction block 609 is in contact with the outer wall of the threaded cylinder 607. The extrusion block 610 is slidably disposed on one side of the fixed frame 608, and one end of the extrusion block 610 is provided with an inclined surface corresponding to one end of the friction block 609, and the other end of the extrusion block 610 is provided with an arc surface corresponding to the extrusion strip 602.

[0024] The specific implementation is as follows: During the process of the traction frame 3 driving the main rib to rotate, the rotation of the main rib can drive the mounting frame 501 to rotate and drive the support frame 502 to rotate. During the rotation of the support frame 502, since the fixed frame 608 is installed on one side of the support frame 502 and the threaded cylinder 607 is rotatably installed inside the fixed frame 608, the threaded cylinder 607 can be driven to move as the support frame 502 rotates. Furthermore, when the threaded cylinder 607 moves to a certain position, the extrusion block 610 moves to the gap between the extrusion bars 602, so that the extrusion block 610 no longer extrudes the friction block 609. At this time, the bevel gear 606 contacts the toothed plate 605. Thus, when the threaded cylinder 607 moves, the bevel gear 606 can rotate under the action of the toothed plate 605, and the threaded cylinder 607 can rotate. In this way, the rotation of the threaded cylinder 607 causes the threaded rod 604 to move, and under the action of the threaded rod 604, it pushes the fixed plate 603 and the connecting cylinder 503 to retract inward, so as to realize the gradual retraction of the connecting cylinder 503. Furthermore, when the extrusion block 610 moves out of the gap between the extrusion bars 602 and re-engages with the extrusion bars 602, the bevel gear 606 separates from the toothed plate 605. At the same time, under the action of the extrusion bars 602 on the extrusion block 610, the extrusion block 610 re-extrudes the friction block 609. Since the corresponding positions of the extrusion block 610 and the friction block 609 are inclined surfaces, the friction block 609 can be extruded by the extrusion block 610 to prevent the threaded cylinder 607 from rotating. In actual application, the number of rotations of the bevel gear 606 after the fixed frame 608 rotates once can be changed by replacing the toothed plate 605 with different numbers of teeth.

[0025] like Figure 10 As shown, the guide assembly 8 includes a fixed base 808 mounted on one side of the mounting base 7, and a shaping wheel set 809 mounted on one side of the fixed base 808; Rotary seat 803 is rotatably mounted at one end of fixed seat 808; The guide assembly 8 also includes a support bar 807, which is mounted on one side of the mounting base 7 and is arc-shaped, and is located between the fixed base 808 and the rotating base 803. Extrusion wheel 806 is installed on one side of support bar 807; The guide assembly 8 also includes: a second limiting wheel 805, which is mounted on one side of the rotating seat 803 and corresponds to the shaping wheel assembly 809; The first limiting wheel 804 is disposed at one end of the rotating seat 803, and the axis of the first limiting wheel 804 is parallel to the side of the rotating seat 803. The guide assembly 8 also includes: a plug plate 802, which is slidably disposed in the groove on the top surface of the rotating seat 803, and one end of the plug plate 802 is inserted into a through hole on one side of the support bar 807, and the support bar 807 is provided with multiple through holes on one side. The second spring 801 is installed at the other end of the insert plate 802, and the other end of the second spring 801 is fixedly connected to the rotating seat 803.

[0026] The specific implementation is as follows: During the process of wrapping the stirrup, the stirrup can be inserted into the shaping wheel group 809 from one side of the fixed seat 808 and pass under the extrusion wheel 806 so that the stirrup passes through the inner side of the second limiting wheel 805 and the first limiting wheel 804, thereby connecting one end of the stirrup to the main bar, and gradually wrapping around the outer wall of the main bar as the main bar rotates; Furthermore, the sliding insert plate 802 can be used to separate it from the through hole on the outside of the support bar 807, so that the rotating seat 803 can be rotated to form an angle between the rotating seat 803 and the fixed seat 808. At the same time, under the action of the extrusion wheel 806, the stirrup can be bent to a certain extent, so that the bending arc of the stirrup matches the arc of the outer wall of the steel cage, thereby reducing the stress when the stirrup is wrapped around the outer wall of the main reinforcement.

[0027] Working principle: When processing the steel cage, the main reinforcement bars are passed through the connecting cylinder 503 and one end of the main reinforcement bars is connected to the traction frame 3. The main reinforcement bars can then be moved by the moving frame 2, and the traction frame 3 and the main reinforcement bars can be rotated by the driving device. The stirrups can be passed through the forming wheel group 809 and under the extrusion wheel 806, then through the gap between the second limit wheel 805, and extend from under the first limit wheel 804, so that one end of the stirrup is connected to the main reinforcement bar. As the main reinforcement bar rotates, the stirrups are wrapped around the outer wall of the main reinforcement bar. At the same time, the stirrups can be bent to a certain extent under the action of the extrusion wheel 806 by changing the included angle between the rotating seat 803 and the fixed seat 808. Furthermore, during the process of the stirrups surrounding the outer wall of the main reinforcement, the main reinforcement can be supported by the connecting cylinder 503 and the support wheel 509. At the same time, the rotation of the main reinforcement can drive the mounting frame 501 and the support frame 502 to rotate. During the rotation, the engagement between the bevel gear 606 and the toothed plate 605 drives the threaded cylinder 607 to rotate. Under the rotation of the threaded cylinder 607, the threaded rod 604 moves, which pushes the connecting cylinder 503 to move and causes the reinforcement cage to gradually retract. During the movement of the connecting cylinder 503, the second cantilever rod 506 can be moved. The connection between the second cantilever rod 506 and the connecting groove 507 pulls the support rod 508 to rotate, thereby changing the position of the support wheel 509.
