[0030] According to an embodiment of the present invention, an auxiliary device for hoisting precast cap beams is provided.

[0031] Example 1;

[0032] like Figures 1-4As shown, the precast cap beam hoisting auxiliary device according to an embodiment of this utility model includes a support frame 1. The bottom of the support frame 1 is connected to two fixed guide rails 2. The inner walls of the two fixed guide rails 2 are movably connected to first lead screws 3 with oppositely distributed threads at both ends. The two ends of the two first lead screws 3 are connected to two symmetrically distributed sliders 4. The bottom of each pair of sliders 4 is connected to a movable guide rail 5. The inner walls of the two movable guide rails 5 are movably connected to second lead screws 6 with oppositely distributed threads at both ends. The outer walls of the two second lead screws 6 are symmetrically distributed with two support blocks 7. This facilitates the clamping and positioning of precast cap beams of different sizes, thereby improving the applicability and effectively improving the convenience of operation, solving the problem of time-consuming and labor-intensive operation caused by cumbersome operation.

[0033] In this embodiment, the inner wall of the support frame 1 is connected to a fixing frame 21. The fixing frame 21 is distributed in a "+" shape when viewed from above, which facilitates the reinforcement and support of the support frame 1 and improves the overall stability.

[0034] Regarding how to clamp the precast cap beam, this embodiment further explains that a fixing nut 8 is connected to the inner wall of the support block 7, and a movable screw 9 is movably connected to the inner wall of the fixing nut 8. One end of the movable screw 9 that extends into the support block 7 is connected to a positioning block 10, which facilitates the sliding of the movable screw 9 through the thread when it is rotated, thereby causing the movable screw 9 to drive the positioning block 10 to slide and clamp and position the precast cap beam.

[0035] Based on the above embodiments, the present invention further explains that both ends of the two first lead screws 3 extending out of the fixed guide rail 2 are connected to first synchronous pulleys 11, and the outer walls of each pair of first synchronous pulleys 11 are connected to a first synchronous belt 12, thereby facilitating the synchronous rotation of the two first synchronous pulleys 11 in each group through the first synchronous belt 12, and thus facilitating the synchronous rotation of the two first lead screws 3.

[0036] Based on the above embodiments, this utility model further explains that the two ends of the two second lead screws 6 extending out of the movable guide rail 5 are connected to the second synchronous wheel 13, and the outer wall of each pair of second synchronous wheels 13 is connected to a second synchronous belt 14, which facilitates the two second lead screws in each group to rotate synchronously through the second synchronous belt 14, thereby facilitating the two second lead screws 6 to maintain synchronous rotation.

[0037] In this embodiment, the top and bottom of the two second synchronous belts 14 are flat, and the middle of the two second synchronous belts 14 are V-shaped. The V-shaped ends of the two second synchronous belts 14 are connected to fixed tensioning wheels 20. The fixed tensioning wheels 20 are rotatably connected to the outer wall of the fixed guide rail 2 via a shaft, which facilitates the guiding and tensioning of the second synchronous belts 14.

[0038] To facilitate the synchronous rotation of the two second lead screws 6 after the position of the movable guide rail 5 is adjusted, this embodiment further describes that the top of the support frame 1 has four sets of fixed blocks 15 symmetrically distributed in pairs. Each set of fixed blocks 15 has two blocks, and a fixed rod 16 is connected between every two fixed blocks 15. The outer wall of each fixed rod 16 is fitted with a return spring 17. One end of each return spring 17 is connected to a movable frame 18 that is slidably connected to the fixed rod 16. The inner wall of the movable frame 18 is rotatably connected to a movable tensioning wheel 19 that is connected to the second synchronous belt 14. This facilitates the adaptive tensioning adjustment of the second synchronous belt 14 by the movable frame 18 driving the movable tensioning wheel 19 through the elasticity of the return spring 17.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] In practical application, the first lead screw 3 is first rotated, causing it to drive a first synchronous pulley 11 to rotate. This causes the first synchronous pulley 11 to drive the first synchronous belt 12 to slide, which in turn drives the other first synchronous pulley 11 to rotate. This results in the two lead screws 3 rotating synchronously. Subsequently, the two lead screws 3, through opposite threads at their ends, drive the slider 4 to slide in opposite directions. This, in turn, causes the slider 4 to drive the movable guide rail 5 to slide in opposite directions. During this process, after the two movable guide rails 5 slide, they will drive the second synchronous pulley 13 to slide in opposite directions, thus causing the second... When the timing belt 14 is loosened or tightened, the elasticity of the return spring 17 causes the movable frame 18 to drive the movable tension wheel 19 to self-adjust, so that the movable tension wheel 19 drives the second timing belt 14 to maintain a taut state. Thus, after the position of the movable guide rail 5 is adjusted, the two second lead screws 6 can maintain synchronous rotation. Then, through the synchronous rotation of the second timing wheel 13 driven by the second timing belt 14, the second lead screw 6 can be moved to drive the two sets of support blocks 7 to slide in opposite directions or in opposite directions. This facilitates the clamping and positioning of precast cover beams of different sizes and effectively improves the scope of application.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
