Description

Technical Field

[0001] The present invention relates to the technical field of steel cage forming, and in particular to steel cage forming equipment and a preparation method thereof. Background Art

[0002] In reinforced concrete structure construction, the steel cage serves as the core load-bearing framework, and its quality directly impacts the structure's load-bearing capacity, durability, and overall stability. Uniform placement of transverse reinforcement is a key factor in ensuring proper stress distribution within the cage. However, during actual construction, inconsistent transverse reinforcement spacing often occurs due to improper worker operation, inadequate positioning measures, or negligent on-site management. This can degrade the cage's performance and even pose risks to project quality.

[0003] In recent years, as building structures have developed towards larger spans, higher heights, and greater complexity, the requirements for the machining accuracy of steel cages have become increasingly stringent. However, some construction companies still tend to "focus on the number of steel bars and neglect spacing control," believing that as long as the number of steel bars meets the design requirements, they ignore the potential risks brought about by spacing deviations. In fact, uneven spacing of transverse reinforcements will change the structure's stress pattern, reducing the synergistic performance of concrete and steel, and thus affecting the component's bending, shear, and seismic resistance. In addition, in concealed projects such as pile foundations and underground continuous walls, spacing issues with steel cages are often not discovered until after pouring is completed. At this time, the cost of rectification is high and may even lead to safety accidents. Summary of the Invention

DETAILED DESCRIPTION

[0053] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0054] First embodiment:

[0055] Combine Figure 1 、 Figure 2 and Figure 4 A steel cage forming device includes a support frame 2 and a control console 3 (the control console can adopt 10-00-ZD-14C-00). One end of the support frame 2 is provided with a longitudinal reinforcement pushing device 1 for pushing longitudinal reinforcements; the other end of the support frame 2 is provided with a transverse reinforcement conveying device 6 for conveying transverse reinforcements, a bending device 7 for bending transverse reinforcements, a welding device for welding longitudinal reinforcements and transverse reinforcements, and an output material rack 5 for conveying welded steel cages; the transverse reinforcement conveying device 6 is arranged below the welding device; the support frame 2 is provided with a measuring device 9 for measuring the length of the longitudinal reinforcement pushed; the control console 3 is connected to the measuring device 9, the longitudinal reinforcement pushing device 1, the transverse reinforcement conveying device 6, the bending device 7 and the welding device;

[0056] The above-mentioned measuring device 9 is arranged between the longitudinal reinforcement pushing device 1 and the welding device; the above-mentioned measuring device 9 is provided with 3 groups, and the 3 groups of measuring devices 9 and the longitudinal reinforcement pushing device 1 are arranged along the length direction of the support frame 2. When the above-mentioned longitudinal reinforcement pushing device 1 pushes the longitudinal reinforcement, the measuring device 9 measures the pushing length of the longitudinal reinforcement, and the above-mentioned control console 3 compares the pushing lengths in pairs. The middle position of the three pushing lengths can be taken as the first preset length, or the first preset length can be set separately, and the longitudinal reinforcement pushing device 1 can be controlled to compensate for the pushing length of the longitudinal reinforcement.

[0057] The measuring device can be used to detect the actual pushing distance of the longitudinal reinforcement during actual use. When the actual value deviates from the theoretical value and is less than a certain value, the system records the deviation value and can compensate for it during the current movement or the next movement. If the deviation value is greater than a certain value, the system will alarm, indicating that the mechanism may be abnormal and needs to be checked. Or the longitudinal reinforcement pushing device 1 directly controls the moving distance with the detection value of the measuring device 9. Two sets of measuring devices simultaneously detect whether the longitudinal reinforcement conveying is offset during the conveying process. That is, the measuring devices on both sides can measure the conveying distance separately, and then compensate for both sides separately, so that the workpiece remains straight and the spacing is controllable over the entire length. The longitudinal reinforcement pushing device 1 can be driven by independent servo motors on both sides, and can independently move both sides to complete compensation according to the detection value; among them, the reasons for the inconsistent errors on both sides may be assembly clearance, clamping slippage, mechanism rigidity and other factors.

[0058] The transverse reinforcement and the longitudinal reinforcement are welded to form a steel cage. The accuracy of the longitudinal reinforcement pushing length will affect the welding position of the transverse reinforcement on the longitudinal reinforcement, and further affect the transverse reinforcement spacing. A measuring device 9 is set in the equipment to measure the longitudinal reinforcement pushing length, and at least two groups are provided. When the longitudinal reinforcement pushing device 1 pushes the longitudinal reinforcement, the measuring device 9 measures the pushing length of the longitudinal reinforcement. The control console 3 compares the two groups of pushing lengths and controls the longitudinal reinforcement pushing device 1 to compensate for the pushing length of the longitudinal reinforcement. Through multiple groups of measurement and compensation mechanisms, the accuracy of the longitudinal reinforcement pushing length is improved; when the accuracy of the longitudinal reinforcement pushing length is improved, the welding position of the transverse reinforcement on the longitudinal reinforcement is also improved, which indirectly improves the control accuracy of the transverse reinforcement spacing and reduces the transverse reinforcement spacing deviation caused by the error in the longitudinal reinforcement pushing length.

[0059] Second embodiment:

[0060] Combine Figure 3 and Figure 4 The longitudinal reinforcement pushing device 1 includes a base frame 11, on which a slide rail 12 and a sliding beam 13 adapted to the slide rail 12 are provided;

[0061] The sliding beam 13 is provided with a plurality of first clamping mechanisms 14, which are used to clamp the longitudinal reinforcement;

[0062] When the console 3 is in the push mode, the sliding beam 13 approaches the support frame 2, and the first clamping mechanism 14 clamps the longitudinal reinforcement; when the sliding beam 13 moves away from the support frame 2, the first clamping mechanism 14 releases the longitudinal reinforcement;

[0063] When the control console 3 is in the compensation mode, the control console 3 controls the corresponding first clamping mechanism 14 to clamp the longitudinal reinforcement and move the sliding beam 13 .

[0064] In a specific embodiment, the longitudinal reinforcement pushing device 1 further includes a plurality of second clamping mechanisms 15 , which are arranged on the support frame 2 , and the second clamping mechanisms 15 correspond one-to-one to the first clamping mechanisms 14 ;

[0065] When the console 3 is in the push mode, the sliding beam 13 approaches the support frame 2, and the second clamping mechanism 15 releases the longitudinal reinforcement; when the sliding beam 13 moves away from the support frame 2, the second clamping mechanism 15 clamps the longitudinal reinforcement;

[0066] When the control console 3 is in the compensation mode, the control console 3 controls the corresponding second clamping mechanism 15 to release the longitudinal reinforcement and move the sliding beam 13 .

[0067] The first clamping mechanism 14 and the second clamping mechanism 15 are composed of a fixed block 18, a cylinder and a rack 17, and are combined Figure 5 The fixed block 18 is connected to the support frame 2, and the fixed block 18 is provided with a guide cavity 16, and the longitudinal rib passes through the guide cavity 16; the cylinder is arranged on the fixed block 18, and the output shaft of the cylinder extends into the guide cavity 16, and the rack 17 is arranged in the guide cavity 16. The rack 17 is connected to the output shaft of the cylinder, and the longitudinal rib is clamped by the extension and contraction of the cylinder.

[0068] A usage scenario for reference, in which the longitudinal reinforcement is connected by the first clamping mechanism 14 and the second clamping mechanism 15. When the steel cage forming equipment is just put into use, the first clamping mechanism 14 clamps the longitudinal reinforcement from the end of the base frame 11 away from the support frame 2 and gradually approaches the support frame 2. The longitudinal reinforcement extending out of the first clamping mechanism 14 gradually penetrates into the second clamping mechanism 15. The second clamping mechanism 15 is provided with a guide tube 19 at the front and rear, and the guide tube 19 is connected to the guide cavity 16; the guide tube 19 extends to the welding device, and the longitudinal reinforcement penetrating the second clamping mechanism 15 stops the movement of the sliding beam 13 when it extends out of the guide tube 19. After that, the cyclic production of the steel cage can begin (pushing the longitudinal and transverse reinforcements, bending and welding the transverse reinforcements), and the measuring device 9 monitors each pushing. The longitudinal reinforcement length is measured, and then the longitudinal reinforcement pushing device 1 is controlled to compensate for its length; the longitudinal reinforcement pushing device 1 can be divided into 3 groups (first edge group, middle group and second edge group). When the pushing length of the first edge group is measured to be 10 cm, the pushing length of the middle group is measured to be 10 cm, and the pushing length of the second edge group is measured to be 9 cm, the length of the second edge is compensated separately, specifically: the first clamping mechanism 14 of the first edge group is controlled to clamp the longitudinal reinforcement, the second clamping mechanism 15 is controlled to release the longitudinal reinforcement, and after the sliding beam 13 is pushed forward 1 cm, the second clamping mechanism 15 clamps the longitudinal reinforcement (this is only an example and not a standard for actual operation).

[0069] Third embodiment:

[0070] Combine Figure 6The measuring device 9 includes a fixed bracket 91, and a sliding mechanism 92 and a grating ruler 93 are arranged in parallel on the fixed bracket 91. A first clamping member 94 is arranged on the sliding mechanism 92, and the first clamping member 94 is connected to the grating ruler 93. The grating ruler 93 includes a scale grating and an indicator grating, and the scale grating is arranged on the fixed bracket 91; the indicator grating is arranged on the scale grating, and the indicator grating is connected to the first clamping member 94. The indicator grating reciprocates in the length direction of the scale grating.

[0071] The first clamping member 94 may be composed of an HFZ32 and a clamping claw. The first clamping member 94 is used to clamp the longitudinal reinforcement. When the longitudinal reinforcement is pushed, the first clamping member 94 moves along with the longitudinal reinforcement, so that a direct physical connection is established between the first clamping member 94 and the longitudinal reinforcement. When the longitudinal reinforcement moves forward, the first clamping member 94 will inevitably produce a corresponding displacement along the pushing direction. Through the linkage relationship, real-time tracking and measurement of the pushed length of the longitudinal reinforcement can be achieved;

[0072] The above-mentioned fixed bracket 91 is also provided with a reset member 95, which can be composed of a cylinder MAL 25x175-SU and a reset belt. The two ends of the above-mentioned reset belt are respectively connected to the fixed bracket 91 and the first clamping member 94; the output shaft of the above-mentioned driver is connected to a push part that fits the reset belt. When the above-mentioned first clamping member 94 releases the longitudinal reinforcement, the driver pushes the output shaft to apply force to the reset belt, and the reset belt pulls the first clamping member 94 to reset.

One end of the connecting rod 63 is connected to the discharge end of the conveying column 62, and the other end is connected to the limiting plate 64. The limiting plate 64 is used to abut against the end of the transverse rib. The second clamping member 65 is slidably provided on the connecting rod 63 and is used to clamp the transverse rib.

[0076] The pushing mechanism 66 includes a pushing plate and a pushing member, which may be a cylinder. The pushing member is disposed on the support frame 2, and the pushing plate is connected to the output shaft of the cylinder. The pushing plate is used to push the transverse rib forward when the second clamping member 65 releases the transverse rib.

[0077] The above-mentioned second clamping member 65 can be composed of a cylinder and two clamping plates, one clamping plate is set on the cylinder, and the other clamping plate is set on the cylinder output shaft; the above-mentioned second clamping member 65 slides on the connecting rod 63 (sliding can be achieved by a linear bearing in combination with the cylinder), thereby dragging the transverse reinforcement to abut against the limit plate 64 to achieve positioning. When dragging the transverse reinforcement, it can be dragged twice to avoid bending the transverse reinforcement before it is dragged into place, resulting in asymmetry of the main reinforcement frame after bending.

[0085] The bending mechanism 74 includes a bending roller 72 and a driving member 73, and the driving member 73 is connected to the bending roller 72;

[0086] A bending cavity for bending the transverse ribs is formed between the bending roller 72 and the positioning wheel 71. The bending cavity is used to accommodate the transverse ribs. Driven by the driving member 73, the bending roller 72 moves in a circular motion around the center of the positioning wheel 71, so that the two ends of the transverse ribs are bent toward each other to form a main rib frame.

[0106] The control console 3 first controls the vertical slide 86 of the upper drive mechanism 82 to move upward to a second preset height, and then controls the longitudinal slide 85 of the upper drive mechanism 82 to move backward to a third preset length, thereby resetting the upper drive mechanism 82 and the welding device.

[0107] The control console 3 controls the vertical slide 86 of the lower driving mechanism 83 to move downward to a first preset height, thereby resetting the lower driving mechanism 83 and the welding device.

[0108] Eleventh embodiment:

[0109] When the control console 3 is in the pushing mode and the longitudinal reinforcement pushing device 1 pushes the longitudinal reinforcement forward, the first clamping mechanism 14 clamps the longitudinal reinforcement; when the longitudinal reinforcement pushing device 1 moves backward, the first clamping mechanism 14 releases the longitudinal reinforcement;

[0110] When the control console 3 is in the compensation mode, the control console 3 controls the corresponding first clamping mechanism 14 to clamp and move the longitudinal reinforcement.

[0111] In a specific embodiment, when the control console 3 is in the pushing mode and the longitudinal reinforcement pushing device 1 pushes the longitudinal reinforcement forward, the second clamping mechanism 15 releases the longitudinal reinforcement; when the longitudinal reinforcement pushing device 1 moves backward, the second clamping mechanism 15 clamps the longitudinal reinforcement;

[0112] When the control console 3 is in the compensation mode, the control console 3 controls the corresponding second clamping mechanism 15 to release and move the longitudinal reinforcement.
