Description

Technical Field

[0001] The invention relates to the technical field of steel cage welding, in particular to a welding reinforcement device for a steel cage. Background Art

[0002] As an important structural component in construction projects, steel cages are widely used in the construction of concrete foundations, bridges, tunnels and other fields. They are composed of longitudinal steel bars and circumferential steel bars (i.e. stirrups). The longitudinal steel bars are responsible for bearing axial tension and pressure, while the stirrups play a role in restraining the longitudinal steel bars and improving the overall stability of the structure. The quality of the steel cage directly affects the structural safety and stability of the project, so its processing and welding process requirements are extremely strict.

[0003] However, the existing steel cage processing methods mainly rely on manual or partial auxiliary equipment for welding and assembly. The traditional production model not only relies on a large number of manual operations, but also has cumbersome procedures. Operators need to position, fix and weld the steel bars one by one. Not only is the operation intensity high and the work efficiency low, but the manual operation error is large, making it difficult to ensure the quality and structural stability of the steel cage. Especially in the production of steel cages with complex shapes or large specifications, manual welding is difficult to meet the production requirements of high precision and high efficiency.

[0004] In addition, the design of existing auxiliary equipment is often relatively simple, and it is impossible to achieve comprehensive control and adjustment of the steel cage processing process. For example, in the welding reinforcement process of the steel cage, there is a lack of precise spacing adjustment, external support and internal support adjustment means, which directly affects the structural stability and welding quality of the steel cage. At the same time, since most existing equipment does not take into account the special needs of steel cage welding, such as the bending of stirrups and the support of longitudinal bars, it is difficult to achieve precise control of each part during the processing process, resulting in quality fluctuations during the welding process.

[0005] At present, the production and processing of steel cages still rely on manual operation and simple mechanical assistance, which cannot effectively improve production efficiency and ensure product quality. Especially in the production of steel cages with high strength and high precision requirements, the shortcomings of traditional methods are becoming more and more obvious. Therefore, there is an urgent need for a dedicated steel cage welding reinforcement equipment. Summary of the invention

The drive motor B63 maintains a power connection with the transmission sprocket A62.

[0087] When the threaded shaft B61 is in operation, it can drive the sliding seat 53 to slide stably in the corresponding outer slide groove 23, thereby realizing the posture adjustment of the external support component 501.

The worm wheel A67 is fixedly connected to the connecting shaft B651, and a mounting shaft A631 is fixedly connected to the output shaft of the drive motor B63, and the mounting shaft A631 is fixedly connected to the worm gear A68.

[0090] When the outer ring seat 2 is driven by the spacing adjustment component to slide in the assembly sleeve 1, the driving gear B66 rotatably installed thereon always maintains a sliding connection with the spline shaft 65. When the driving motor B63 drives the connecting shaft B651 and the spline shaft 65B to operate through the combination of the worm A68 and the worm wheel A67, the power can be transmitted to the driving gear B66, thereby driving the transmission gear B611 and the corresponding threaded shaft B61 to operate stably.

[0091] The combination of worm wheel A67 and worm A68 also has the characteristics of speed reduction and torque increase and one-way self-locking. When the driving motor B63 drives the worm A68 and worm wheel A67 to operate, the rotation speed of the worm wheel A67, the connecting shaft B651 and the spline shaft 65 can be reduced and the torque can be increased, so that the spline shaft 65 can drive the driving gear B66 to operate stably.

[0092] The power of the driving motor B63 can only be transmitted to the worm wheel A67 through the worm gear A68 for rotation. When the driving motor B63 stops, the worm wheel and the connecting shaft B651, the spline shaft 65, and the driving gear B66 are all in a locked state, thereby enabling the outer support assembly 501 to stably maintain a specific retracted and extended posture.

[0093] In order to ensure that the inner retractable components can be stably installed and to synchronously retract and adjust the inner support components 502 assembled on the inner ring seat 3, the following technical solution is provided.

[0094] The inner retractable assembly includes a threaded shaft C71, a transmission sprocket B72, a drive motor C73, and a matching combination of a worm wheel B74 and a worm B75. Multiple groups of threaded shafts C71 are rotatably installed in the inner ring seat 3. The threaded shafts C71 are arranged relative to the inner slide groove 32 and are rotationally connected to the sliding seat 53. The same end of each group of threaded shafts C71 is fixedly connected to a transmission sprocket B72. Each group of transmission sprockets B72 realizes chain transmission through a chain B76. The drive motor C73 is fixedly installed on the mounting base plate 13 and arranged on the outside of the mounting sleeve 1. The output shaft of the drive motor C73 is fixedly connected to a mounting shaft B731. The mounting shaft B731 is fixedly connected to the worm B75, and the worm wheel B74 is fixedly connected to one of the groups of threaded shafts C71.

[0095] The combination of the worm wheel B74 and the worm gear B75 also has the characteristics of speed reduction and torque increase and one-way self-locking, so as to ensure that the driving motor C73 can drive the threaded shaft C71 to operate stably, and drive each group of threaded shafts C71 to operate synchronously through the combination of the transmission sprocket B72 and the chain B76, and can drive the corresponding sliding seat 53 to slide stably in the corresponding inner slide groove 32, thereby realizing the synchronous adjustment of the posture of the support assembly 502 in each group.

The inner ring gear B81 is rotatably installed in the assembly sleeve 1, the driving motor D82 is fixedly installed on the mounting base plate 13, the driving gear C83 is fixedly connected to the output shaft of the driving motor D82 and keeps meshing with the inner ring gear B81, the fixed bracket 84A is fixedly installed on the inner bottom of the assembly sleeve 1, the rotating bracket 85 is fixedly connected to the inner ring gear B81, the telescopic cylinder A86 and the telescopic cylinder B87 are respectively fixedly installed in the fixed bracket 84 and the rotating bracket 85, the support wheel 88 is assembled to the movable end of the telescopic cylinder A86, and the clamp 89 is assembled to the movable end of the telescopic cylinder B87.

[0099] A strip through hole 16 arranged opposite to the support wheel 88 is opened on the assembly sleeve 1, so that the steel bars used for processing stirrups can be input into the assembly sleeve 1 from the strip through hole 16. The support wheel 88 and the clamp 89 are respectively driven by the telescopic cylinder A86 and the telescopic cylinder B87 for lifting and lowering adjustment. The support wheel 88 is used to stably support the steel bars and fit them with the outer side of the longitudinal reinforcement, and the clamp 89 is used to clamp the inner end of the steel bars.

[0100] When the driving motor D82 drives the driving gear C83 to operate, it can drive the inner ring gear B81 and the rotating bracket 85 and the clamp 89 installed thereon to operate synchronously, and then the steel bars clamped by the clamp 89 are bent into annular stirrups under the action of the supporting wheel 88, so that the stirrups are arranged on the periphery of each longitudinal reinforcement, and the stirrups are welded and fixed to each longitudinal reinforcement with the help of staff.
