Abstract

The utility model relates to a traction hook which is used in transportation operation and is also used as a lifting hook. The utility model is composed of a hook (1) and a safety clamp (2), wherein, the hook (1) is divided into a hanging ring and a hook body, the safety clamp (2) composed of a tongue piece (3) and a spring (4) is arranged at the opening part of the hook body and is fixed with the hook body through a pin (5), and the safety clamp (2) can automatically close the opening of the hook body to prevent the hooked objects from falling off. The utility model has the advantages of convenient use, safety, material benefit, high durability and high efficiency, and can avoid the latent hidden danger in traction and lifting operations. The utility model can be widely used for the traction, the lifting the labor power climbing of sea, land and air transportation operations, and is particularly suitable for the traction when large, medium and miniature automotive vehicles happen malfunctions and ships run aground. Thus, the utility model is an ideal article used for traction and lifting operations.

Description

Crane hook

The utility model relates to the hauling hook in a kind of hauling operation, also can make Lift hook and use.

Traction in the transit industry, lifting operation, in the past rope tools such as steel wire, palm fibre, fiber crops that adopt add fastener to the two ends bending of rope for one section and form suspension hook more.Need spanner to tighten up when this class rope uses, easily puncture hand and other position of human body when holding, also need use the oils maintenance, easily produce grease, wet heavy.Also occur normal traction, Lift hook afterwards, all do not had the insurance countrmeasure.Facts have proved that above-mentioned rope or common hook are prone to and come off, fall sliding phenomenon, cause goods landing breakage when the hook object is operated; Also can produce bounce-back during traction and touch the person, damage accident, produce immeasurable economic loss.Obviously, it is low that existing rope and common hook exist safety factor, and the drawback that potential risk is many is brought certain difficulty to hauling operation.

The purpose of this utility model is exactly the drawback that has traction, hoisting technology existence now for overcoming, and a kind of safety factor height is provided, and the potential risk of forgoing does not need special curing, has the hauling hook of safety device.

This hauling hook is made up of hook and insurance card two parts.Main body is a hook, and hook is divided into suspension ring and opening coupler body part, and the coupler body opening part is provided with insurance card, and insurance card is made up of tongue piece and spring, and spring is pressed into the tongue piece bottom land that the cross section is flute profile, is connected and fixed on the coupler body opening part by the suspension ring end by pin.When traction, lifting operation, the opening safety card, behind the hook object, insurance card prevents the object slippage by action of the spring auto-closing coupler body opening.Materials such as hauling hook main body system employing carbon constructional quality steel are made, and finished product traction, lifting dynamics can reach 29.4KN(3T)-100KN(10T).

Hauling hook is compared with rope and common hook, has esy to use, safe and reliable, durable, the operating efficiency advantages of higher of material benefit, the traction, lifting and the manpower that are widely used in the sea, land and sky carrier are climbed, as various large, medium and small type power actuated vehicle et out of orders, traction when the naval vessel is stranded; The climbing of industries such as electric industry, forestry, railway shunting; The goods lifting on forest farm, goods yard, harbour and airport etc.This hauling hook is the desirable articles for use of traction, lifting operation, promotes the practical value height, and development prospect is wide.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the hauling hook front view

Fig. 2 is the hauling hook left view

The utility model is introduced embodiment below in conjunction with accompanying drawing.This hauling hook integral body is divided into hook (1) and insurance card (2) two large divisions, and hook (1) adopts the 45# carbon constructional quality steel to forge and processes, and suspension ring and opening coupler body part are arranged.Insurance card (2) places the coupler body opening by the suspension ring end, form by tongue piece (3), curved spring (4), tongue piece (3) cross section is flute profile, adopting steel plate to bend forms, torsion spring (4) exit is pressed in tongue piece (3) bottom land, whole insurance card (2) is connected and fixed on coupler body (1) by pin (5), and the outer external part of pin (5) adopts the riveted joint location.Insurance card (2) is auto-closing coupler body (1) opening when no external force effect quiescence.
