Abstract

The utility model discloses a sling which can remove a hook automatically, in order to resolve problems that present loading-unloading process needs workers to remove hooks of slings, costs too much time, force and labor and is unsafe. The sling comprises a lifting ring arranged on a lifting cable of a crane and a hook body under the lifting ring, wherein the middle portion of a weight iron block is hinged in the lower portion of the lifting ring, the hook can be rotationally connected with an end of the weight iron block in the lifting ring, and another end of the weight iron block is provided with a weight block. The weight block is provided with a bias angle opened towards to the hook when objects are lifted. The invention can utilize the gravity of the weight iron block and the continuous action of the hook and the weight iron block to remove the hook automatically, thereby during working worker is separated from goods, to improve safety, reliability and efficiency and reduce labor force.

Description

But automatic releasing hook formula suspender

Technical field

The utility model belongs to handling tool, and the specifically a kind of coupler body of suspension hook and hoist cable of goods of can making extractd the suspender of disengaging automatically.

Background technology

Need collude the displacement of on the goods hoist cable, slinging with the suspension hook of suspender during with the crane handling goods, when goods moves on to the destination when putting down, need remove another part goods hoist cable of hook again with artificial suspension hook is taken off from the hoist cable of goods, so just need special decoupling devices when goods falls such as staff; This artificial decoupling device is especially to handling large cargo inconvenience, because of goods big, also need on swashing, goods climb down during staff's decoupling device, take a lot of work, effort, time-consuming, inefficiency, and pin is stepped on and has been slided the easy tumble injury of falling down when climbing goods, and the situation that suspension hook throws up the people that damages also happens occasionally, and people's goods does not separate very dangerous.

The utility model content

Technical problem to be solved in the utility model is, overcome existing handling goods need with the suspension hook of manual removal's suspender take a lot of work, effort, time-consuming and unsafe shortcoming, but a kind of automatic releasing hook formula suspender is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: suspender comprises the suspension ring that are installed on the crane hoist cable and following hook thereof, the middle part of balance weight iron hinged in suspension ring below, hook can be connected an end of balance weight iron with rotating in suspension ring, the other end of balance weight iron is provided with clump weight, on described clump weight, the angle of laying particular stress on of being partial to the hook opening when slinging goods is arranged.

The described angle of laying particular stress on is to have more one and the asymmetric angle of opposite side on a jiao of clump weight.

When hook was not also hung the hoist cable of goods, action of gravity made the clump weight end of balance weight iron be in the below of whole suspender, causes the hook opening to make progress automatically, was convenient to be suspended on the hoist cable of goods be not easy to make the goods sling falling again; When slinging goods, the weight of goods is rotated down hook to be in the lifting state, and the clump weight of balance weight iron is laid particular stress on the angle simultaneously along with rotating up automatically to the suspension ring of suspender because of balance weight iron is provided with, and makes a side of its deflection suspension hook opening; When goods lands, suspender is along with the goods hoist cable is lax, action of gravity is rotated down balance weight iron automatically along the suspension hook opening direction, drive the opening up rotation down of hook, until the whole state down of the opening of hook, make the goods hoist cable fall automatic releasing hook automatically, under the effect of balance weight iron, the opening of hook goes to preparation upwards again and hangs state after the decoupling device.

Advantage of the present utility model and good effect be, owing to utilized the gravity principle of balance weight iron and the interlock effect of hook and balance weight iron to realize automatic releasing hook, people's goods separates in the operating process, and is safe and reliable, and high efficiency is saved manually, and labour intensity is low.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, Fig. 2, suspender comprises the suspension ring 4 that are installed on the crane hoist cable, bearing pin 3 passes the hinge axis hole 5.2 (referring to Fig. 3, Fig. 4) at balance weight iron 5 middle parts, hinged below suspension ring 4 both sides the seat hole in, one end of balance weight iron 5 is a clump weight 5.3, the other end is the ear seat 5.5 of band pin-and-hole 5.1, and pin-and-hole 5.1 is parallel with hinge axis hole 5.2 line of centerss; The shank of hook 1 is bearing in the pin-and-hole 5.1 by pin 2, and hook 1 can freely be rotated at the interior ring of suspension ring 4;

When goods was landed, suspender was along with the goods hoist cable is lax, and gravity is rotated down balance weight iron automatically along hook 1 opening direction, on described clump weight 5, be provided with when slinging goods, can be partial to hook 1 opening lay particular stress on angle 5.4.The described asymmetric angle that has more on nearly hook 1 opening one side angle that angle 5.4 can be a clump weight 5.3 when slinging goods of laying particular stress on also can be to fix a pouring weight on a side angle on the symmetrical both sides on the clump weight 5.3.

Among Fig. 5, when also not hanging the hoist cable of goods on the hook 1, action of gravity makes clump weight 5.3 ends on the balance weight iron 5 be in the below of whole suspender, causes hook 1 opening to make progress automatically, is convenient to be suspended on the hoist cable of goods be not easy to make the goods sling falling again.

Among Fig. 6, when goods lands, suspender is along with the goods hoist cable is lax, action of gravity makes the clump weight 5.3 of balance weight iron 5 lay particular stress under the effect at angle 5.4 at it, automatically the opening direction along hook 1 is rotated down, and the opening that drives hook 1 is towards the below, and the bottom surface of its hook 1 is up rotation upwards, until the whole state down of the opening of hook 1, make the decoupling device that comes off automatically from the hook of hook 1 automatically of goods hoist cable.

Claims

But 1, a kind of automatic releasing hook formula suspender, comprise the suspension ring that are installed on the crane hoist cable and following hook thereof, it is characterized in that: the middle part of balance weight iron hinged in suspension ring below, hook can be connected an end of balance weight iron with rotating in suspension ring, the other end of balance weight iron is provided with clump weight, on described clump weight, the angle of laying particular stress on of being partial to the hook opening when slinging goods is arranged.
But 2, automatic releasing hook formula suspender as claimed in claim 1 is characterised in that: the described angle of laying particular stress on, be on a jiao of clump weight, have more one, with the asymmetric angle of opposite side.
