Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically an anchor bar bending device. Background Technology

[0002] In the field of construction engineering, cast-in-place piles, as an important foundation structure, are widely used in large-scale projects such as ports, bridges, and industrial plants. Anchor bars, as key load-bearing components connecting the pile structure to the superstructure, directly affect the connection strength between the pile and the superstructure and the overall safety of the project due to their bending quality. Therefore, anchor bar bending is one of the critical procedures in pile construction.

[0003] Traditional anchor bar bending operations utilize pulley and rope-assisted bending devices, requiring a team of four workers. The specific process involves two workers supporting the bending machine and adjusting its position, one worker operating the pulley and rope to provide auxiliary tension, and another worker checking the anchor bar's position and bending angle. This operating mode has significant drawbacks: First, it requires a large amount of manpower, with four workers working together leading to high labor costs, especially during the remaining work phase after the initial construction phase, where personnel allocation becomes more difficult. Second, it is extremely labor-intensive, requiring workers to continuously apply tension through pulleys and ropes, leading to fatigue over long periods, reducing efficiency, and potentially affecting the bending accuracy due to operational errors. Third, it lacks safety; the coordination between pulleys and ropes relies on the workers' teamwork, and improper coordination can cause the bending machine to shake or the rope to slip, posing a risk of mechanical injury. Fourth, it has low efficiency; the complex personnel coordination process results in a long bending time for a single anchor bar, making it difficult to meet construction schedule requirements during tight deadlines for remaining work.

[0004] Therefore, developing an anchor bar bending device that can reduce manual labor input, lower labor intensity, and improve efficiency and safety has become an urgent need to solve current construction problems. Utility Model Content

The adapter plates 611 at the bottom of the sleeve rod 62 are rotatably connected to the first ear plate 31 by a pin. This structure facilitates the rotatable connection between the telescopic rod 6 and the supporting rod 5 and the sleeve 3. The bottom of the adjusting rod 61 is provided with an insert rod 613, which is inserted into the inside of the sleeve rod 62. The side of the sleeve rod 62 near the top is provided with a set screw 621.

[0059] like Figure 9 As shown, it also includes a spring 7, with hooks 71 at both the top and bottom of the spring 7. The hooks 71 are hung on the hanging ring 55, which facilitates the disassembly and assembly of the spring 7 and allows the spring 7 to be adjusted or replaced according to usage requirements.

[0060] like Figure 10As shown, it also includes a connecting rope 8, with a connecting ring 81 at its top. The connecting ring 81 is connected to the hook 71 at the bottom of the spring 7, facilitating the assembly and disassembly of the connecting rope 8 and its flexible use. The connecting rope 8 can be configured to have an adjustable length, allowing for length adjustment according to usage requirements. Furthermore, the bottom of the connecting rope 8 has a binding opening 82 for securing it to a hydraulic pipe bending machine.

[0061] Working Principle: In use, the entire device is fixed near the anchor bar that needs to be bent. By rotating the support rod 4 and the support rod 5, the support rod 5 is positioned above the anchor bar. Then, the spring 7 is hung on the hanging ring 55, and the connecting rope 8 is connected to the hook 71 at the bottom of the spring 7. Finally, the bottom end of the connecting rope 8 is tied to the hydraulic pipe bending machine. The operator can then hold the hydraulic pipe bending machine to bend the anchor bar. The operator only needs to control the direction of the bending. The cooperation of the spring 7 and the connecting rope 8 effectively prevents the hydraulic pipe bending machine from falling. Simultaneously, the spring 7 provides an upward pulling force to the hydraulic pipe bending machine, thus avoiding the operator needing to expend excessive force to operate it. Furthermore, the support rod 5 can be angled and rotated, facilitating the bending of all anchor bars in the entire cast-in-place pile.

[0062] In summary, compared with the prior art, this application, by setting up a base 1, a bottom cover 2, a sleeve 3, and a support rod 4, allows the sleeve 3, in conjunction with the support rod 4 and the bottom cover 2, to rotate relative to the base 1, facilitating the flexible use of the entire device. The support rod 5 is rotatably connected to the support rod 4, facilitating the adjustment of the angle of the support rod 5. The telescopic component can be adjusted in length according to usage requirements, thereby facilitating the adjustment of the angle of the support rod 5. This structure allows the entire bending device to be flexibly adjusted, making it easy to adapt to different working scenarios.
