Description

Technical Field

[0001] The utility model relates to the field of attachment devices, and particularly relates to a climbing frame attachment device at the structural discontinuity. Background Technique

[0002] The climbing frame, also known as the lifting frame, can be mainly divided into hydraulic type, electric type, manual hand-pulled type, etc. according to its power source. It is a new type of scaffolding system developed in recent years and is mainly applied to high-rise shear wall buildings. It can climb or descend along the building. This system has completely changed the scaffolding technology: firstly, there is no need to turn the scaffold; secondly, the disassembly and assembly process of the scaffold is eliminated (it is used until the construction is completed after one-time assembly), and it is not restricted by the height of the building, greatly saving manpower and materials. And from the safety perspective, it has also greatly improved compared with the traditional scaffold. It has great development advantages in high-rise buildings.

[0003] In the prior art, the climbing frame attachment device at the structural discontinuity is an important part of the attached lifting scaffold (climbing frame) system. It mainly plays a role in stably attaching the climbing frame to the building structure to ensure the safe and stable operation of the climbing frame during the lifting and lowering process. However, since most of the existing attachment devices are fixed to the wall through wall bolts and bolts, when installed at the structural discontinuity of the building, the opening will cause damage to the structure of this part, thus affecting the stability of the attachment device after connection and reducing the support stability of the climbing frame. At the same time, due to the gap between the climbing frame and the wall, and the overall structure of the attachment device is fixed and not easy to adjust, it is impossible to quickly connect with the climbing frame, and the distance between the guide wheels on the attachment device cannot be adjusted, resulting in the inability to make the guide wheels fully fit with the guide rails according to the width between the climbing frame guide rails when connecting climbing frames of different sizes, causing the problem of shaking when the climbing frame is in use. Furthermore, it not only reduces the connection and installation efficiency between the climbing frame and the attachment device, but also reduces the flexibility and stability of the attachment device during use.

[0023] As Figure 3As shown in the figure, adjustment openings 9 are respectively provided on the top surface and the bottom surface of the telescopic cylinder 5. The telescopic rod 10 is inserted and installed inside the telescopic cylinder 5. Threaded short rods 11 are respectively fixedly installed on the top surface and the bottom surface of the telescopic rod 10. The threaded short rods 11 are movably installed in the adjustment openings 9 and pass through the adjustment openings 9. The second bolts 12 are threadedly connected to the threaded short rods 11. Drag the telescopic rod 10 in the forward direction according to the gap distance between the wall 1 and the climbing frame body 2. The threaded short rods 11 provided on the top surface and the bottom surface of the telescopic rod 10 will move in the adjustment openings 9 provided on the top surface and the bottom surface of the telescopic cylinder 5. After the telescopic rod 10 is moved out of the telescopic cylinder 5 to an appropriate distance, screw the second bolts 12 onto the threaded short rods 11 and threadedly connect them together. Thus, the use length of the attachment mechanism 3 can be adjusted according to the distance between the climbing frame body 2 and the wall 1, so that the climbing frame body 2 can be connected to the wall 1 through the attachment mechanism 3;

[0024] As Figure 4 shown in the figure, the concave front seat 14 is fixedly installed at the front end of the telescopic rod 10. A sliding opening 15 is provided on the side wall of the concave front seat 14. Rotation holes 16 are respectively provided on both sides of the inner wall of the concave opening of the concave front seat 14. Rotating rods 18 are respectively fixedly installed at both ends of the bidirectional screw rod 17. The rotating rods 18 are movably installed in the rotation holes 16. A knob 19 is also fixedly installed on the outer end wall of one of the rotating rods 18. Manually rotate the knob 19 to drive the rotating rod 18 to rotate in the rotation hole 16, so that the rotating rod 18 drives the bidirectional screw rod 17 to rotate. The sliding opening 15 provided on the concave front seat 14 is used to cooperate with the sliding of the slider 22;

[0025] As Figure 4 shown in the figure, the two adjusting plates 20 are symmetrically arranged left and right. A threaded hole 21 is provided on the side wall of the adjusting plate 20. The adjusting plate 20 is threadedly connected to the bidirectional screw rod 17 through the threaded hole 21. A slider 22 is also fixedly installed on the left side of the adjusting plate 20 and is movably installed in the sliding opening 15. A fixing hole 23 is also provided on the side wall of the adjusting plate 20. A bearing 24 is fixedly installed in the hole of the fixing hole 23.

And during the up and down movement of the climbing frame body 2, the guide wheels 25 will rotate. When rotating, the rotating shafts 26 on the outer side walls of the guide wheels 25 will rotate in the bearings 24 installed in the fixing holes 23 opened on the side walls of the adjusting plates 20. In this way, it plays a guiding role for the climbing frame body 2, and by adjusting the distance between the guide wheels 25, the attachment mechanism 3 can adapt to the use of climbing frame bodies 2 of different sizes.
