Description

Technical Field

[0001] The utility model relates to the field of building construction safety protection devices, in particular to a barrier-free card passing device for a safety rope. Background Art

[0002] Building construction refers to production activities during the implementation phase of engineering construction. It is the process of building various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. During scaffolding high-altitude operations, construction workers need to wear safety ropes to ensure safety. The scaffolding construction area is generally large, and construction workers need to frequently walk on the scaffolding during the operation. Therefore, in order to ensure convenient construction, the safety rope on the safety belt worn passes through the safety cable fixed node. There will be the following problems when walking during construction: (1) During the construction process, the safety rope on the safety belt is easily hooked on the safety cable fixed node and cannot be moved, posing a major safety hazard. The traditional method is to use both hands to remove the safety rope buckle from the safety cable. However, the work is cumbersome and time-consuming, and construction workers often hold construction tools while working, which is inconvenient to operate; (2) Ordinary fasteners are used to fix the safety cable on the steel pipe to form a safety rope fixing point. Although this can ensure construction safety, the safety rope buckle is in a locked state. Therefore, when construction workers are walking, the safety rope buckle cannot pass through the safety rope fixing point smoothly. It is necessary to temporarily remove the safety rope buckle to bypass the safety rope fixing point. Once the safety rope buckle is removed, the construction workers will be in a state without safety protection measures and there is a risk of slipping and falling, which does not comply with safety construction regulations.

[0006] Furthermore, the fastener is a butterfly bolt.

[0007] Furthermore, a washer is sleeved on the butterfly bolt.

[0008] Furthermore, anti-slip sheets are provided on the inner walls of the first fastener and the second fastener.

[0009] Furthermore, the inner diameter of the round tube buckle formed by the first fastener and the second fastener is the same as the outer diameter of the scaffolding steel pipe.

[0010] Furthermore, the thickness of the transverse portion of the hanging rope portion is 4-5 mm.

[0011] Furthermore, the total height of the hanging rope portion is less than the total longitudinal height of the inner cavity of the dedicated buckle of the safety rope.

[0012] Furthermore, the height of the transverse portion of the hanging rope portion is smaller than the opening width of the dedicated buckle for the safety rope, and the opening width of the dedicated buckle for the safety rope is smaller than the outer diameter of the safety cable.

[0013] Furthermore, the inner diameter of the rope threading hole is larger than the outer diameter of the safety cable.
