[0002] In the field of construction engineering, steel reinforcement cage, as the core framework of pile foundation, column and other structures, plays a key role in bearing load, enhancing structural strength and stability. However, the traditional steel reinforcement cage welding process has significant shortcomings in efficiency, quality and applicability, which is difficult to meet the demand of modern engineering for high efficiency, precision and low cost.

[0003] Patent application No. CN202411295443.8 discloses a steel reinforcement cage welding equipment, which comprises a horizontal reinforcement support frame and a driving mechanism arranged at one end of the horizontal reinforcement support frame and used for driving the horizontal reinforcement to rotate.

The terms "vertical", "horizontal", "left", "right" and the like used herein are only for illustrative purposes.

[0034] As shown in Figures 1 to 8 The present application provides a reinforcing cage welding device, which comprises a welding frame 1, a support frame 2 for supporting longitudinal bars arranged on the welding frame 1 in sequence, a traction frame 3 for pulling the longitudinal bars, a mounting mechanism 4 for mounting the longitudinal bars on the support frame 2, and a pushing mechanism 5 for pushing the longitudinal bars on the support frame 2 to the traction frame 3.

[0035] The support frame 2 is composed of a mounting frame 21 and a rotating disc 22; the mounting frame 21 is fixedly connected with the welding frame 1; the rotating disc 22 is rotatably mounted on the mounting frame 21;

[0036] The mounting mechanism 4 is composed of a pushing assembly 41 and a locking assembly 42;

[0037] The pushing assembly 41 comprises a conveying roller 411 conveying longitudinal ribs, and a cylinder one 412 pushing the longitudinal ribs to be clamped to the support frame 2;

[0038] When the staff needs to install the longitudinal rib on the welding frame 1, the staff places the longitudinal rib on the conveying roller 411 through the carrying device, starts the driving motor on the conveying roller 411, and drives the conveying roller 411 to rotate to convey the longitudinal rib to the bottom of the mounting frame; then the cylinder one 412 pushes the longitudinal rib upward; the longitudinal rib on the conveying roller 411 is close to and clamped to the rotating disc 22 on the support frame 2; the carrying device can be preferably a manipulator, a crane;

[0039] The locking assembly 42 comprises mounting grooves 421 equidistantly opened at the edge of the rotating disc 22, clamping blocks 422 fixedly installed in the mounting grooves 421, a stop block 423 rotatably installed on the rotating disc 22, a reset spring 424 driving the stop block 423 to reset, a stop rod 425 unidirectionally blocking the stop block 423, and a motor one 426 driving the rotating disc 22 to rotate;

[0040] When the longitudinal rib is conveyed to the preset (end of the conveying roller 411) position at the bottom of the mounting frame, the cylinder actuator is started to push the longitudinal rib upward, so that it gradually approaches the rotating disc 22 and is finally inserted into the preset mounting groove 421 on the rotating disc 22. During the insertion of the longitudinal rib into the mounting groove 421, it will first contact the stop block 423, and under the continuous pushing action of the longitudinal rib, the stop block 423 will deflect. When the longitudinal rib further moves forward and completely passes the stop block 423, the stop block 423 is automatically reset to the initial position under the elastic restoring force of the reset spring 424, and at this time, the longitudinal rib is reliably clamped between the clamping structure formed by the clamping block 422 and the stop block 423.

[0041] When the cylinder actuator completes the pushing action and retracts, the stop block 423 is mechanically limited by the stop rod 425, and always maintains the relative position relationship with the mounting groove 421, so as to ensure that the longitudinal rib will not be accidentally removed from the mounting groove 421, thereby realizing the quick and accurate installation and fixation of the longitudinal rib on the rotating disc 22, and completing the clamping process of a single longitudinal rib.

[0042] Subsequently, the driving motor is started, and since the output shaft of the motor and the rotating disc 22 are fixedly connected through a reliable transmission connection mode (such as key connection, flange connection, etc.), when the motor operates, the power will be transmitted to the rotating disc 22 through the output shaft to drive the rotating disc 22 to rotate; with the rotation of the rotating disc 22, the plurality of mounting grooves 421 distributed thereon will be rotated to the lower end of the pre-set longitudinal rib butt joint station in turn, and be accurately aligned with the longitudinal rib to be installed; at this time, the cylinder actuator again acts to push the next longitudinal rib into the corresponding mounting groove 421, and the above installation process is repeated until the fixing work of all longitudinal ribs required by the reinforcement cage is completed.

[0043] Thus, the mechanical feeding mode is used to replace the manual longitudinal rib perforation work, thereby reducing the problem of work staff injury caused by the horizontal rib slipping and reducing the welding efficiency.

[0044] It should be noted that the support frame 2 is provided with two groups, the rotating discs 22 on the two support frames 2 are fixedly connected through the synchronous rod 427, and the cylinder one 412 is also provided with two groups, so that when the longitudinal rib needs to be installed on the support frame 2, the two ends of the longitudinal rib are simultaneously pushed up by the two groups of cylinder one 412 and are fixed on the support frame 2, respectively.

[0045] The pushing mechanism 5 comprises a push plate 51, a cylinder two 52 for driving the push plate 51 to move, and a tensioning assembly 53 for supporting the middle part of the longitudinal rib; the push plate 51 and the piston rod of the cylinder two 52 are rotationally connected through a rotating ring;

[0046] When the longitudinal rib (referred to as longitudinal rib) is reliably positioned and clamped on the two side support frames 2, the cylinder two 52 is started and drives the push plate 51 to move along the guide rail structure of the welding frame 1 to the traction frame 3 in a pre-set straight line track. During the translation of the push plate 51, its effect is embodied as double cooperative functions:

[0047] Firstly, the push plate 51 applies a continuous pushing force to the longitudinal rib carried on the support frame 2 through mechanical contact, and pushes the longitudinal rib to translate along the axial direction to the butt joint of the traction frame 3; secondly, the push plate 51 forms a rigid contact constraint with the surface of the longitudinal rib, and through the dynamic abutment effect, the longitudinal rib group is calibrated in real time to eliminate the axial misalignment caused by machining error or clamping deviation, so that the end faces of the plurality of longitudinal ribs are strictly aligned to form a regular and orderly parallel array structure.

[0048] The synchronous calibration function: on the one hand, the straightened longitudinal rib group can be quickly and reliably coupled with the positioning clamp of the traction frame 3 through the standardized interface, significantly improving the assembly efficiency and structural stability of the reinforcement cage framework; on the other hand, in the case of insufficient length of the steel bar raw material, the pre-calibration process can effectively avoid the secondary trimming operation of the manual docking link - in the traditional process, if the longitudinal rib has an axial length deviation, the end of the steel bar needs to be trimmed by a manual cutting tool, which not only consumes time and effort but also easily introduces processing errors. The pre-straightening technology of the push plate 51 can completely avoid such redundant procedures, thereby significantly reducing the intensity of manual intervention and optimizing the automation level and labor productivity of the overall process.

[0049] The tensioning assembly 53 comprises a connecting rod 531 fixedly connected with the push plate 51, a sliding block 532 fixedly connected with the connecting rod 531, a support rod 533 equidistantly hinged on the sliding block 532, a hinged rod 534 hinged at the other end of the support rod 533, a hinged ring 535 hinged at the other end of the hinged rod 534, and the hinged ring 535 is fixedly installed on the synchronous rod 427; the sliding block 532 is slidingly installed on the synchronous rod 427; one end of the support rod 533 is provided with an arc block 536.

[0050] When the cylinder two 52 actuator is started and drives the push plate 51 to move linearly along the predetermined stroke path, the push plate 51 drives the connecting rod 531 to produce translational displacement through the mechanical linkage mechanism, and the connecting rod 531 further transmits the driving force to the sliding block 532, driving the sliding block 532 to slide along the axial direction of the synchronous rod 427. In this process, the support rod 533 group connected with the sliding block 532 through the hinge pair expands in space in the form of an umbrella-shaped radiation, and the expansion trajectory conforms to the preset geometric divergence law.

[0051] As the support rod 533 group continues to expand outward, the arc-shaped support block arranged at the end gradually approaches the longitudinal rib axis and finally forms a conformal contact constraint with the outer contour of the longitudinal rib. Based on the bionic curved surface design principle, the arc-shaped support block implements spatial steady-state maintenance on the longitudinal rib through multi-point distributed support, effectively inhibiting the cantilever beam bending deformation of the longitudinal rib due to the self-weight effect or external disturbance. The support mechanism can form dynamic stiffness compensation, ensuring that the longitudinal rib always maintains axial straightness during the process of passing through the positioning station of the support frame 2, avoiding unintended lateral interference between the longitudinal rib and the positioning elements such as the clamping block 422 and the blocking block 423 of the support frame 2.

[0052] Through the above mechanical compensation strategy, the influence of longitudinal rib flexural deformation on positioning accuracy can be eliminated, and the risk of block 422-stop block 423 mechanism overload caused by longitudinal rib deviation can be avoided, preventing the plastic deformation or fatigue damage of the positioning element due to continuous loading, thereby ensuring the stability of the positioning function and the durability of the support frame 2, and providing reliable spatial reference conditions for the subsequent longitudinal rib clamping and steel cage skeleton forming process.

[0053] Here, it is summarized that when the longitudinal rib is fixedly installed on the support frame 2, the air cylinder two 52 pushes the push plate 51 to move towards the traction frame 3, on the one hand, it pushes the longitudinal rib to translate along the axial direction to the butt joint of the traction frame 3; on the other hand, it supports the longitudinal rib to prevent the longitudinal rib from causing the outward bending force on the block 422 and the stop block 423 on the support frame 2 when passing through the support frame 2.

[0054] The traction frame 3 is composed of a frame body 31, a rotating disc 32, a mounting hole 33, a tightening bolt 34, and a moving assembly for moving the frame body 31; the frame body 31 is slidingly installed on the welding frame 1, the rotating disc 32 is rotatably installed on the frame body 31, the mounting hole 33 is equidistantly arranged on the rotating disc 32, and the tightening bolt 34 is screwed into the mounting hole 33;

[0055] When the air cylinder two 52 pushes the longitudinal rib to approach the traction frame 3 and passes through the mounting hole 33, the tightening bolt 34 is tightened by the wrench to fix the longitudinal rib passing through the traction frame 3.

[0056] The moving assembly is composed of a driving motor two 351, a gear one 352, a gear two 353, and a roller 354; the motor two 351 is fixedly installed on the traction frame 3, the gear one 352 is fixedly connected with the output shaft of the motor, the gear one 352 is engaged with the gear two 353, and the gear two 353 is coaxially connected with the roller 354;

[0057] When one end of the longitudinal rib is fixedly installed on the traction frame 3, the motor two 351 is started, the motor two 351 drives the gear one 352 to rotate, the gear two 353 synchronously rotates with the gear one 352 to synchronously drive the roller 354 to rotate, and the roller 354 drives the traction frame 3 to move on the welding frame, thereby pulling the horizontal rib to make the coil rib gradually coil around the horizontal rib.

[0058] It is supplemented here that the device is also provided with a welding machine for spot welding the points of the longitudinal rib and the coil rib; the welding machine is a prior art which will not be described in detail here.
