Description

Technical Field

[0001] The utility model belongs to the technical field of climbing frames, in particular to a climbing frame anti-falling fixing safety device. Background Art

[0002] Climbing frames are also called lifting frames. According to their power sources, they can be divided into several main categories, such as hydraulic, electric, and manual. It is a new type of scaffolding system developed in recent years, mainly used in high-rise shear wall buildings. It can climb up or down along the building. This system has completely changed the scaffolding technology: first, there is no need to turn over the frame; second, the disassembly and assembly process of the scaffolding is eliminated (it is used until the construction is completed after one assembly), and it is not limited by the height of the building, which greatly saves manpower and materials. And from the perspective of safety, it has also made great changes to traditional scaffolding. It has great development advantages in high-rise buildings. In order to improve the safety factor of the climbing frame, a fall prevention device is generally installed at the climbing frame.

[0003] For example, the publication number CN 21455600 U is a wall-mounted fixed anti-fall device for a climbing frame. This anti-fall device assists the resetting of the anti-fall pendulum block by setting a spring. Since the spring is unstable, the stability of the anti-fall device is low and safety accidents are prone to occur. At the same time, the structure of the anti-fall device is relatively complex, resulting in high production costs. In order to solve the above problems, a climbing frame anti-fall fixed safety device is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a climbing frame anti-falling fixing safety device in order to solve the above-mentioned problem.

[0005] The technical solution adopted by the utility model is as follows: a climbing frame anti-falling fixing safety device, comprising:

[0006] An anti-fall fixing mechanism, which is fixedly installed on the wall, and the anti-fall fixing mechanism also includes a fixing seat, a clamping block is welded in the middle of one side of the fixing seat, a connecting groove is opened on the front side of the clamping block, and a plurality of guide grooves are opened at equal distances on the left and right sides of the connecting groove, and an anti-falling lever is slidably connected between the two guide grooves at the bottom;

[0007] The anti-fall rack is fixedly mounted on the outer wall of the climbing frame, and the anti-fall rack also includes a connecting portion, and a plurality of tooth-shaped portions are integrally arranged on one side of the connecting portion.

[0008] Through the above technical scheme, the anti-fall fixing mechanism is fixedly installed on the wall, and the anti-fall rack is fixedly installed on the side of the climbing frame close to the wall. When the climbing frame is in the process of rising, it drives the anti-fall rack to move upward. During the rising process of the anti-fall rack, the toothed portion on its surface pushes the anti-fall lever upward. When the lower end of the toothed portion passes the anti-fall lever, the anti-fall lever is quickly reset by its own weight. When the climbing frame falls, the lower wall of the toothed portion is directly pressed on the upper wall of the anti-fall lever. Due to the limitation of the guide groove, the anti-fall lever is fixed in place, thereby supporting the anti-fall rack, thereby realizing the anti-fall function. The overall device has a simple structure and low production cost. At the same time, it does not need to be reset by a spring, and has higher stability.

[0009] In a preferred embodiment, a locking pin is threadedly connected to the top of the block.

[0010] Through the above technical solution, when the climbing frame needs to be lowered, it is only necessary to move the anti-fall lever to the uppermost end of the guide groove and insert the locking pin into the block. At this time, the locking pin blocks the anti-fall lever to prevent it from re-entering the lowermost end of the guide groove, so that the climbing frame can be quickly lowered along the anti-fall fixing mechanism.

[0011] In a preferred embodiment, the guide groove is arranged obliquely downward.

[0012] Through the above technical solution, when the anti-fall lever moves to the uppermost end of the guide groove, it can be automatically reset under the influence of gravity.

[0013] In a preferred embodiment, a plurality of threaded holes are provided on both left and right sides of the fixing base.

[0014] Through the above technical solution, the fixing base is fixedly installed on the wall through the threaded holes.

[0015] In a preferred embodiment, the tooth-shaped portion is a right-angled triangle structure.

[0016] In a preferred embodiment, notches matching the toothed portion are formed at both upper and lower ends of the clamping block.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is: the utility model proposes a climbing frame anti-falling fixing safety device.

[0018] The anti-fall fixing mechanism is fixedly installed on the wall, and the anti-fall rack is fixedly installed on the side of the climbing frame close to the wall. When the climbing frame is in the process of rising, it drives the anti-fall rack to move upward. During the rising process of the anti-fall rack, the toothed portion on its surface pushes the anti-fall lever upward. When the lower end of the toothed portion passes the anti-fall lever, the anti-fall lever is quickly reset by its own weight. When the climbing frame falls, the lower wall of the toothed portion is directly pressed on the upper wall of the anti-fall lever. Due to the limitation of the guide groove, the anti-fall lever is fixed in place, thereby supporting the anti-fall rack, thereby realizing the anti-fall function. The overall device has a simple structure and low production cost. At the same time, it does not need to be reset by a spring and has higher stability. BRIEF DESCRIPTION OF THE DRAWINGS

During the rising process of the anti-fall rack 2, the toothed portion 22 on its surface pushes the anti-fall lever 15 upward. When the lower end of the toothed portion 22 passes the anti-fall lever 15, the anti-fall lever 15 is quickly reset by its own weight. When the climbing frame falls, the lower wall of the toothed portion 22 is directly pressed on the upper wall of the anti-fall lever 15. Due to the limitation of the guide groove 14, the anti-fall lever 15 is fixed in place, thereby supporting the anti-fall rack 2, thereby realizing the anti-fall function. The overall device has a simple structure and low production cost. At the same time, it does not need to be reset by a spring, and has higher stability.
