Abstract
The utility model relates to a crane hook lock hook device. The crane hook lock hook device comprises a hook located below a crane and is used to hang articles. The crane hook lock hook device is characterized in that a flange is arranged on a vertical rod part above the hook in a sleeved mode, the flange is connected with an iron ring through a first chain shackle, the iron ring is connected with a second chain shackle through a chain, and the second chain shackle is connected with a small hook used to hook the iron ring. The crane hook lock hook device can effectively avoid the accidents that a sling for lifting loads is unhooked and falls down to hurt people caused by falling too much of the hook due to improper operation or crane failure when the crane hangs and delivers goods. The crane hook lock hook device plays a key control role in a safety management objective of 'zero-accident and zero-harm' of a lifting work, plays a great role in life safety protection of staff in companies engaged in lifting works and construction industry, and lifting harm accidents can be reduced greatly.
Description
Technical field
The utility model relates to a kind of crane hook lock hook device, is particularly suitable in the vehicling operation.
Background technology
Present most factory and building site; Transport large-scale in same working space or the widely-used hoisting crane of heavy object; Use large-scale suspender to carry out the handling weight and hoisting crane per tour is long-time (as rolling up with C type hook block at the aluminium processing site; Heavily about 1 ton of each C type hook), crane hook decline might take place when misoperation or hoisting crane fault causes suspender to break off relations and the casualty accident that falls down too much.
And the device of more existing lock hooks all has different shortcoming, as: intensity difference, mounting or dismounting are inconvenient, hinder hand etc. easily.
Summary of the invention
The purpose of the utility model is to provide a kind of crane hook lock hook device, when this device can effectively prevent crane for hoisting during because of misoperation or hoisting crane fault suspension hook descend and cause suspender to break off relations and the casualty accident that falls down too much; " zero accident, zero injury " object of safety management to realizing hoisting operation plays crucial control action, will play huge effect to the enterprise that is engaged in hoisting operation and building industry employee's life security guarantee, can reduce the lifting injury accident greatly.
The utility model is characterised in that: a kind of crane hook lock hook device; Comprise the suspension hook that is positioned at the hoisting crane below and is used to hang object; It is characterized in that: said suspension hook top straight-bar portion is arranged with a flange, and said flange links through the first chain shackle and an iron hoop; Said iron hoop links through the chain and the second chain shackle, and the said second chain shackle links with the little suspension hook that is used to catch on iron hoop.
Further, offer circular hole and the long slot bore that is used to connect the first chain shackle on the above-mentioned flange.
The advantage of the utility model:
1, enough intensity is arranged, effectively play the lock hook effect;
2, change dissimilar suspenders conveniently;
3, use chain to unload buckle, maintenance and replacing are convenient;
4, utilize the flexible connection of hoisting chain, not fragile;
5, safe, do not hinder hand;
6, meet load hook safe handling standard.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the organigram of flange among the utility model embodiment.
Among the figure: 1 is crane hook; 2 is flange; 3 is the first chain shackle; 4 is iron hoop; 5 is chain; 6 is the second chain shackle; 7 is little suspension hook; 8 is the suspension ring of suspender; 11 is crane hook top straight-bar portion; 21 is circular hole; 22 is long slot bore.
The specific embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and cooperates appended graphic elaborating as follows.
With reference to legend; A kind of chain type travelling crane hook lock hook device; Comprise being positioned at hoisting crane below and being used to hang the suspension hook 1 that connects object, it is characterized in that: said suspension hook 1 top straight-bar portion 11 is arranged with a flange 2, and said flange 2 links through the first chain shackles 3 and an iron hoop 4; Said iron hoop 4 links through the chain 5 and the second chain shackle 6, and the said second chain shackle 6 links with the little suspension hook 7 that is used to catch on iron hoop 4.
Offer the circular hole 21 and long slot bore 22 that are used to connect the first chain shackle 3 on the above-mentioned flange 2.
The utility model is in use; With reference to figure 1: the suspension ring 8 that earlier crane hook caught on suspender; Again with chain pass the two ends second chain shackle behind the suspension ring, little suspension hook and iron hoop be linked together, the benefit of 2 aspects is arranged like this: at first owing to receive the constraint suspender of chain to be not easy to break away from, once more from crane hook; Even the suspender on the crane hook breaks away from, also tangle suspender by parts such as chains.Connects for fastening with the connecting mode of the first chain shackle, the second chain shackle and little suspension hook is most of, and little suspension hook is to have safety catch, can prevents little suspension hook disengaging iron hoop like this; The utility model uses, and in enterprising enforcement usefulness of driving such as 6#, 7#, 8#, 9#, 10#, 11#, 21#, 22#, 24#, and reflect effective.
The parts that use in the utility model:
1, flange: adopt refined steel to forge by suspender producer, can bear 3 tons of working loads, 4 times of safety factors; There are 2 holes at the edge, and circular hole and long slot bore cooperate, and can penetrate 3.15 tons of chain shackles.
2, the first chain shackle:, can bear 3.15 tons of working loads, 4 times of safety factors from the buying of suspender producer; The top connects 3 tons of special flanges, and the below connects 3 tons of special hoisting chains.
3, the second chain shackle:, can bear 2 tons of working loads, 4 times of safety factors from the buying of suspender producer; One end connects 3 tons of hoisting chains, and the other end connects 1.5 tons of suspension hooks.
4, little suspension hook:, can bear 1.5 tons of working loads, 4 times of safety factors from the buying of suspender producer; Be connected on the hoisting chain with 2 tons of chain shackles, suspension hook can conveniently be hung the big ring place into assembly three chains; Have safety catch, can effectively prevent self to break off relations.
5, chain: from the buying of suspender producer, diameter 10MM can bear 3 tons of working loads, 4 times of safety factors; The special iron hoop of one end is used to connect 3.15 tons of chain shackles and catches on terminal 1.5 tons of suspension hooks; The other end connects 2 tons of chain shackles; Be about 500MM, according to the design of different rows coupler head, the oversize chain link of removing, too weak point can add the chain shackle.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
