Self-falling-off type clip hook

Abstract

The invention relates to a self-release clip hook, which is characterized in that the structure comprises a big semicircle hook splint with a balancing handle and a small semicircle hook splint with a balance weight. The two splints are hinged to a hook clip with a scissors-like shape by a hinge shaft, rope eyes are arranged at the force arm ends of the two splints. A clamping rope is connected between the rope eyes, and a lifting lug which can be hung by a sling is sleeved on the clamping rope, the balance weight is arranged at the force arm terminal far away from the semicircle hook end. When the nip clips the clipped pendant, because of the deadweight function of the clipped pendant, the sling draws up the clamping rope by the lifting lug and strings the clip hook, and is guided to the destination by a sling. When the tightening pop-up hinging point is arranged by the pendant in order, the sling then looses, the clip port of the splint opens and overturns around the clipped pendant to escape from the clipped pendant under the functions of the deadweight and the balance weight. The self-release clip hook has the advantages of reasonable design, simple structure, stable clamp, automatic release, safety and reliability, thus improving the construction efficiency greatly and guaranteeing the engineering quality.

Description

Technical field: [0001] The invention belongs to the field of hoisting clamps, and in particular relates to a self-detachable clamp hook which can clamp cables through mountains, canyons, rivers, lakes and seas, and can be automatically released, recovered and reused, and is especially suitable for erecting main cables or high-voltage lines of suspension bridges. Background technique: [0002] Existing high-altitude erecting cables used in construction projects, such as the main cables erecting suspension bridges, load-bearing cables in the cable hoisting method, and high-voltage cables in electric power engineering, mostly adopt the method of dragging along the ground. Take the cables for erecting suspension bridges as an example. During construction, the entire bundle of cables is placed on the turntable, and the cable ends are dragged from one end of the tower to the other using tools such as ships or pulling ropes. During the dragging process, the middle part of the cabl...

Problems solved by technology

If ordinary clamps are used to clamp the cable for traction, since the ordinary clamps cannot fall off by themselves after the cable is drawn in place, it must be clamped manually in the air with a crane, which is very dangerous.
