Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 - 7 , the present utility model provides the following technical solutions.

[0032] Embodiment 1: In order to solve the problem that the suspension cable 6 in the prior art is prone to shaking, which affects the stability during the hoisting process. Therefore, in this embodiment, through the following technical solutions, a precast column lifting tool structure that avoids tilting is provided, which is provided with a fixed column 1, a suspension cable 6, a connecting ring 7, an auxiliary support 8, and an auxiliary sleeve 9. The middle of the upper end of the fixed column 1 is provided with a suspension cable 6, and both the left and right sides of the upper end of the fixed column 1 are provided with connecting rings 7. And the upper end of the connecting ring 7 is hingedly connected with an inclined auxiliary support 8, and the upper end of the auxiliary support 8 is hingedly connected with an auxiliary sleeve 9. The auxiliary sleeve 9 covers the outside of the suspension cable 6, and the auxiliary sleeves 9 at the left and right ends are fixed to each other by bolts. As Figure 1 and Figure 4 shown, by flipping the auxiliary support 8, the auxiliary support 8 rotates with the connecting ring 7, and the upper end of the auxiliary support 8 rotates with the auxiliary sleeve 9, so that the auxiliary sleeve 9 covers the outside of the suspension cable 6. Then, the auxiliary sleeves 9 on the left and right sides are limited by bolts. By clamping the suspension cable 6 with the auxiliary sleeve 9, the suspension cable 6 and the fixed column 1 are made more stable, preventing tilting, and greatly improving the stability during the hoisting process.

[0033] Embodiment 2: The existing precast column lifting tool structure for preventing tilting is not convenient to adjust the lifting tool according to the actual placement state of the precast column, such as vertical or horizontal placement. Therefore, by setting a connecting column 10, a movable column 11, a fixed clamping plate 12 and a fixing mechanism 14, the movable column 11 is rotatably connected to the lower end of the connecting column 10, and the movable column 11 drives the fixed clamping plate 12 to flip at the lower end of the connecting column 10. The connecting column 10 and the movable column 11 are limited by the fixing mechanism 14, and an anti-slip rubber pad 13 is arranged on the inner side of the fixed clamping plate 12. The fixing mechanism 14 includes a movable frame 15 sleeved on the lower end of the connecting column 10, a spring 16 arranged between the movable frame 15 and the connecting column 10, fixed blocks 17 fixedly connected to the front and rear sides of the lower end of the connecting column 10, and a positioning column 18 for limiting. A left-right sliding structure is formed between the movable frame 15 and the fixed block 17, and a positioning column 18 is fixedly connected to the outer side surface of the movable frame 15. The positioning column 18 is inserted into one end of the movable column 11 away from the fixed clamping plate 12, as Figure 1 , Figure 5 , Figure 6 and Figure 7 shown. According to the placement state of the precast pile, when the precast column is in a vertical state, the fixed clamping plate 12 and the connecting column 10 are adjusted to the state as shown in Figure 1 . When the precast column is in a horizontally laid state, by pulling the positioning column 18, the positioning column 18 drives the sliding between the movable frame 15 and the fixed block 17. The movable frame 15 squeezes the spring 16, causing the spring 16 to undergo elastic deformation. At this time, the positioning column 18 is disengaged from the movable column 11, thereby releasing the limit between the movable column 11 and the connecting column 10. Then, the fixed clamping plate 12 is flipped by 90°, and the fixed clamping plate 12 drives the movable column 11 to rotate at the bottom of the connecting column 10. The fixed clamping plate 12 and the connecting column 10 are flipped to the state as shown in Figure 7 . Then, the positioning column 18 is directly released. At this time, the spring 16 resumes elastic deformation, driving the sliding between the movable frame 15 and the fixed block 17, so that the movable frame 15 drives the positioning column 18 to be inserted into the outer side surface of the movable column 11, thereby facilitating the limitation between the movable column 11 and the connecting column 10.

[0034] Embodiment 3: The existing precast column lifting structure that avoids tilting has poor stability in clamping the precast column. Therefore, by providing a fixed column 1, a lead screw 2, a connecting plate 3, a movable block 4 and a movable sleeve 5, the middle of the fixed column 1 is rotatably installed with the lead screw 2, and the right end of the lead screw 2 is fixedly connected to the connecting plate 3. The lead screw 2 is threadedly connected to the movable block 4, and the thread directions at the left and right ends of the lead screw 2 are opposite. The movable block 4 is slidably connected to the middle of the lead screw 2, and the movable block 4 is fixedly connected to the movable sleeve 5. The movable sleeve 5 is slidably connected to the left and right ends of the fixed column 1 respectively, and a vertically arranged connecting column 10 is fixedly connected to the lower end of the movable sleeve 5. The movable sleeve 5 drives the fixed clamping plate 12 to clamp and fix the precast column through the connecting column 10. As Figure 1 , Figure 2 and Figure 3 shown, place the fixed clamping plate 12 on both sides of the precast column, drive the lead screw 2 to rotate inside the fixed column 1 by rotating the connecting plate 3. The connecting plate 3 drives the movable blocks 4 on the left and right sides inside the fixed column 1 and the movable block 4 to move towards each other. At this time, the movable block 4 drives the movable sleeve 5 to slide on the outside of the fixed column 1, so that the movable sleeve 5 drives the fixed clamping plate 12 to clamp and position the precast column through the connecting column 10. Moreover, combined with the setting of the anti-slip rubber pad 13, the stability during the clamping process is improved, and at the same time, the outside of the precast column is prevented from being pinched. After the clamping is completed, drive the precast column to move through an external lifting device.
