When the take-up frame 7 swings when the suspension mechanism 2 swings, it can prevent the take-up frame 7 from swinging and also reduce the swing pressure of the suspension mechanism 2.

The two arc-shaped rubber strips 23 at the corresponding positions can slide along the outside of the arc-shaped rod 25 under the sliding sleeve of the card base 22, thereby prompting the steel strands wrapped around the outside of the take-up frame 7 to be clamped to the two arc-shaped rubber strips 23. Between the shaped rubber strips 23, when lifting the take-up frame 7, the steel strands can be wrapped to avoid loosening of the steel strands due to shaking.

Support arms 11 are fixedly installed on the outer walls of both sides of the fixed platform 10. The two support arms 11 are threadedly connected with screw rods 17 on the inner side of one end. A runner 13 is fixedly installed on the outer side of one end of the two screw rods 17. The outer sides of the two guide rods 9 are corresponding to each other. There are clamping holes 18 at the positions of the screw rods 17 . One end of the two screw rods 17 penetrates the inside of the base 8 and is threadedly matched with the inner side of the corresponding clamping hole 18 .

The screw 17 driven by rotation at the support arm 11 can limit the position of the base 8 and other components during use, thereby preventing the base 8 from moving during operation. The positioning frame 14 and the base 8 are slidably installed. object, the position can be adjusted to match the placement of the wire take-up frame 7.

The bottom of the take-up frame 7 is clamped on the inside of the positioning frame 14. , the rectangular opening 27 is pressed against the outer lower side of the take-up frame 7. After positioning, the hydraulic cylinder 24 at the support frame 16 drives the support frame 21 at the telescopic end to approach the outside of one side of the take-up frame 7, and the worker lifts the clamping bar 6 , so that the abutment seat 28 corresponding to the abutment frame 21 can adaptively abut against the inner steel strand surface of the take-up frame 7 under the buffering of the spring 31 according to the number of layers of steel strand wrapping, and the abutment seat 28 abuts against After the wire frame 7 is taken up, the support force between the bottom of the wire take-up frame 7 and the positioning frame 14 is more stable, forming an opposing force with the support 28 and the hydraulic cylinder 24, thus enhancing the strength of the wire take-up frame 7 during the lifting process. Stabilizing effect, at this time, the arc rod 25 and other components can be installed from the outside of the take-up frame 7, and the slots 30 on the inside of the clamping rod 6 are correspondingly clamped to the outer edges of both sides of the take-up frame 7 for fixation. In this way, the When the take-up frame 7 is lifted in the same batch, its stability on the fixed platform 10 can be enhanced, and the dangerous accident of falling from high altitude due to displacement due to swing can be avoided. The card holder 22 of the sliding set can be slid outside the arc-shaped rod 25. The arc-shaped rubber strips 23 on the outside of both ends are driven to move to wrap the outside of the wrapped steel strands to avoid the problem of loosening of the steel strands during lifting. Therefore, during construction, it can assist the take-up frame 7 to carry out safety operations. Improved, the overall operation is safer and more stable, which can greatly improve the use effect.
