Description

Technical Field

[0001] This utility model belongs to the field of steel cage processing technology, and in particular relates to a welding device for prefabricated steel cage stirrups. Background Technology

[0002] Reinforcing cages are a type of steel reinforcement structure frequently used in building construction. The most common type is the cylindrical reinforcing cage, which can serve as the reinforcing skeleton for structures such as load-bearing columns.

[0003] The main structure of the reinforcing cage consists of longitudinal reinforcing bars of a certain length, distributed in a ring. To increase the strength of the reinforcing structure, multiple ring-shaped stirrups are fixed to the outside of the longitudinal reinforcing bars. Specifically, the stirrups are formed by bending steel bars. After the stirrups are fitted onto the outside of the longitudinal reinforcing bars, they are welded and fixed to the longitudinal reinforcing bars.

[0004] Another method involves using a spiral structure for the stirrups, which are coiled around the outside of the longitudinal reinforcement bars and welded in place. This method significantly improves the stability of the entire reinforced concrete structure.

[0005] However, because the stirrups are ring-shaped or spirally coiled, and the fixing points for the longitudinal reinforcement bars are arranged in a ring, the reinforcing cage needs to be constantly rotated during the stirrup fixing process. Since the reinforcing cage, especially for larger structures, is also very large, it becomes very heavy and difficult to rotate. Furthermore, the numerous fixing points for the stirrups necessitate frequent rotation, making the fabrication of the reinforcing cage quite challenging. The workload is also substantial. All these drawbacks make it difficult to fabricate reinforcing cage structures in a simple, convenient, and efficient manner. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a welding device for prefabricated steel cage stirrups.

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

[0008] A precast steel cage stirrup welding device includes a bottom support, with roller structures for supporting the steel cage respectively mounted on both sides of the bottom support, and the steel cage is supported on the roller structures and rotates.

[0009] The bottom support is equipped with a rotating frame structure for driving the steel cage to rotate at both ends. The rotating frame structure includes a rotating frame with several limiting through holes, and the longitudinal bars of the steel cage are limited in the limiting through holes.

[0010] The precast steel cage stirrup welding device also includes an anti-cage movement mechanism installed on the bottom support. During the process of flipping the steel cage to weld the stirrups, the anti-cage movement mechanism prevents the steel cage from moving.

[0011] Preferably, the bottom support is equipped with roller structures that support steel cages on the front and rear sides respectively;

[0012] The idler structure includes idler frames fixed at two positions on the bottom support, and long rollers are rotatably connected to the idler frames.

[0013] Preferably, the roller frame is welded to the bottom support via a connecting beam.

[0014] Preferably, a flipping frame structure is respectively assembled and connected to the front and rear ends of the bottom support; the flipping frame structure further includes a support that rotatably connects to the flipping frame, and a motor that drives the flipping frame to rotate is installed on the rear support.

[0015] The flipping frame has several flipping rods, and limiting through holes are respectively opened on the flipping rods;

[0016] The brackets are respectively installed on the bottom bracket via a spacing adjustment structure.

[0017] Preferably, the spacing adjustment structure includes a raised seat fixedly connected to the top of the bottom support, and a plurality of adjusting horizontal screws slidably connected to the raised seat at the lower end of the support. Each adjusting horizontal screw is threaded with a pair of nuts positioned on both sides of the support.

[0018] Preferably, the anti-cage movement mechanism is located at the center of the support;

[0019] The anti-cage movement mechanism includes a height-adjustable support, on which an anti-movement wheel structure is installed;

[0020] The anti-rolling wheel structure abuts against the steel cage.

[0021] Preferably, the anti-slip wheel structure includes a central anti-slip wheel installed at the center of the adjusting support, and the central anti-slip wheel is vertically arranged;

[0022] The adjustable support is equipped with inclined side anti-roll wheels on both sides, and the two side anti-roll wheels face each other.

[0023] Preferably, the wheel frames of the central anti-slip wheel and the side anti-slip wheel are respectively equipped with vertically arranged vertical screws and inclined screws, and the vertical screws and inclined screws are threadedly connected to the adjusting support.

[0024] Preferably, the bottom bracket is fixedly connected to two sides, and a vertically mounted screw is installed on the protrusion. The vertically mounted screw is slidably mounted on the adjusting support. A pair of adjusting nuts positioned at the top and bottom of the adjusting support are threaded onto the vertically mounted screw.

[0025] This utility model has the following beneficial effects:

[0026] 1. During the operation, after the rebar cage is placed, the operator pushes the tilting frame structure at both ends towards the rebar cage. When the tilting frame approaches the end of the rebar cage, the operator rotates the tilting frame until the longitudinal reinforcing bars on the rebar cage pass through the limiting through holes. The motor is then turned on, and the tilting frame, driven by the motor, tilts the rebar cage. The tilting of the rebar cage in a supported rolling state offers greater flexibility. At this point, the operator welds the stirrups.

[0027] The above method significantly reduces the technical drawbacks of the precast steel cage welding process, which requires turning the cage during the welding of a large number of stirrups. Turning the heavy steel cage is laborious and leads to low welding efficiency and a large workload. Because of the flexible turning mechanism, the operators can easily switch the welding points distributed around the stirrups to a more convenient position during the welding process.

[0028] 2. During operation, the operator adjusts the distance between the central anti-lateral movement wheel and the side anti-lateral movement wheel and the reinforcing cage using the vertical screw and the inclined screw until the central and side anti-lateral movement wheels contact the reinforcing cage. Specifically, the central anti-lateral movement wheel contacts downwards, while the side anti-lateral movement wheels contact the reinforcing cage from a double-layered position. In this manner, the reinforcing cage is double-limited from the top. During the rotation of the reinforcing cage, the central and side anti-lateral movement wheels roll. This method increases the stability of the heavy and long reinforcing cage during the flipping process, preventing it from falling off.

[0029] 3. The device disclosed in this utility model realizes automatic flipping of the steel cage for welding stirrups. In this way, the welding points of the stirrups on the heavy steel cage can be flexibly flipped and adjusted to a position that is convenient for welding. This method greatly reduces the difficulty of welding work and improves the efficiency of welding work. Attached Figure Description

[0040] Example 1

[0041] like Figure 1-5 As shown, a precast steel cage stirrup welding device includes a bottom support 2, with roller structures for supporting the steel cage respectively assembled and connected on the front and rear sides of the bottom support 2, and the steel cage 1 is supported on the roller structures and rotates.

[0042] Specifically, the bottom support 2 has roller structures for supporting the reinforcing cage 1 mounted on its front and rear sides. Each roller structure includes roller frames 32 fixed to the left and right sides of the bottom support 2, with long support rollers 31 rotatably connected to the roller frames 32. The bottom of the reinforcing cage 1 is supported on four long support rollers 31 on its front and rear sides. Because the long support rollers 31 have a certain length, they can maintain relatively stable support.

[0043] The aforementioned roller frame 32 is welded to the bottom support 2 via a connecting beam 321.

[0044] In order to achieve the flipping of the steel cage 1, the front and rear ends of the bottom support 2 are respectively equipped with a flipping frame structure for driving the steel cage to flip 1. The flipping frame structure includes a flipping frame 52, and a number of limiting through holes 521 are opened on the flipping frame 52. The longitudinal bars of the steel cage are limited in the limiting through holes 521.

[0045] Specifically, the structure of the flipping frame 52 also includes a bracket 51 that is rotatably connected to the flipping frame 52. A motor 54 that drives the flipping frame 52 to rotate is installed on the rear bracket 51 (in the existing way, a rotating shaft is fixedly connected to the flipping frame 52, the rotating shaft is rotatably connected to the bracket 51, and the output shaft of the motor 54 is fixed on the rotating shaft, such as by a coupling, and the motor 54 is fixedly installed on the bracket 51, such as by bolts).

[0046] Specifically, the flipping frame 52 has 6 integrally formed flipping rods (the inner ends of the flipping rods are integrally formed), and the limiting through holes 521 are respectively opened on the flipping rods.

[0047] Meanwhile, brackets 51 are installed on bottom brackets 512 via a spacing adjustment structure.

[0048] Specifically, the spacing adjustment structure includes a raised seat 531 fixedly connected to the top of the bottom bracket 512. Several adjusting horizontal screws 53 are fixedly connected to the raised seat 531 and slidably connected to the lower end of the bracket 51. A pair of nuts positioned on both sides of the bracket 51 are threaded onto the adjusting horizontal screws 53 respectively.

[0049] During the operation, after the steel cage 1 is placed, the operator pushes the flipping frame 52 structure at both ends toward the steel cage 1. When the flipping frame 52 is close to the end of the steel cage, the operator rotates the flipping frame 52 until the longitudinal reinforcing bar on the steel cage 1 passes through the limiting through hole 521.

[0050] At this time, the operator adjusts the nuts to press and position them on both sides of the bracket 51 (loosen the nuts during the sliding adjustment of the bracket 51), thus keeping the bracket 51 fixed.

[0051] When motor 54 is turned on, the tilting frame 52 tilts the steel cage, which is supported by the rolling mechanism, allowing for greater flexibility in tilting the steel cage 1. At this time, the operator welds the stirrups (the stirrups can be pre-fitted onto the steel cage).

[0052] In actual operation, the stirrups at both ends and the center of the steel cage 1 are pre-welded and fixed to maintain the stability of the entire device. Then, it is lifted by a crane onto the support roller 31. The remaining large number of stirrups are continuously welded and fixed during the subsequent welding process, as the steel cage 1 is rotated.

[0053] The above method greatly reduces the technical defects of the precast steel cage 1, which requires turning the cage over when welding a large number of stirrups during the welding process. Turning the heavy steel cage 1 over is laborious, resulting in low welding efficiency and a large workload.

[0054] The flexible flipping mechanism allows operators to easily switch the welding points distributed around the circumference of the stirrups to a convenient welding position during the welding process.

[0055] Example 2

[0056] like Figure 1-5 As shown, this embodiment, based on the structure of embodiment 1, avoids the drawback of the reinforcing cage 1 easily shifting (moving upwards or outwards) during the welding process, which could lead to the reinforcing cage easily detaching.

[0057] The precast steel cage stirrup welding device also includes an anti-cage movement mechanism 4 installed on the bottom support 512. During the process of rotating the steel cage to weld the stirrups, the anti-cage movement mechanism 4 prevents the steel cage from moving. The anti-cage movement mechanism 4 is located at the center of the support 51.

[0058] Specifically, the anti-cage movement mechanism 4 includes an adjustable support 41 with adjustable height (located above the cage structure; the adjustable support 41 is pre-disassembled during the hoisting of the steel cage), and an anti-movement wheel structure is installed on the adjustable support 41, which abuts against the steel cage.

[0059] Specifically, the anti-slip wheel structure includes a central anti-slip wheel 44 installed at the center of the adjusting support 41. The central anti-slip wheel 44 is vertically arranged, and side anti-slip wheels 45 are installed on both sides of the adjusting support 41 at an incline. The side anti-slip wheels 45 on both sides are arranged facing each other.

[0060] The central anti-slip wheel 44 and the side anti-slip wheel 45 are respectively equipped with a vertically arranged vertical screw 43 and an inclined screw, which are threadedly connected to the adjusting support 41.

[0061] During operation, the operator adjusts the distance between the central anti-slip wheel 44, the side anti-slip wheel 45 and the reinforcing cage using the vertical screw 43 and the inclined screw until the central anti-slip wheel 44 and the side anti-slip wheel 45 contact the reinforcing cage. Specifically, the central anti-slip wheel 44 contacts downwards, and the side anti-slip wheel 45 contacts the reinforcing cage from a double-layer position. In this way, the reinforcing cage is double-limited from the top. During the rotation of the reinforcing cage, the central anti-slip wheel 44 and the side anti-slip wheel 45 roll.

[0062] The bottom bracket 512 is fixedly connected to two sides of the bottom bracket 421 respectively. Vertical mounting screws 42 are installed on the vertical mounting screws 421. The vertical mounting screws 42 are slidably installed on the adjusting support 41. A pair of adjusting nuts positioned at the top and bottom of the adjusting support 41 are threaded onto the vertical mounting screws 42.

[0063] By adjusting the support 41 and slidingly connecting the vertical mounting screw 42, the height of the central anti-movement wheel 44 and the side anti-movement wheel 45 can be further adjusted, so that the central anti-movement wheel 44 can be pressed downwards and the side anti-movement wheel 45 can be pressed against the steel cage from the double layer.

[0064] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
