Abstract
The utility model relates to an automatic unhook lift hook, comprising a lift hook, a chain, and a connecting ring for connecting the lift hook and the chain. The automatic unhook lift hook is characterized in that the automatic unhook lift hook also comprises an automatic unhook device. The automatic unhook device is provided with a connecting portion, and is fixedly connected with the connecting ring. The automatic unhook lift hook is used, i. e, after the chain of a traveling crane lifts and transports an object to arrive at a destination, the chain looses and does not bear force, the self-weight of a heavy block is used, the automatic unhook lift hook and a heavy object lifted are automatically separated, and the purpose of unhooking is achieved. The automatic unhook lift hook is convenient and practical, and is convenient to be maintained in actual work using, the labor intensity of workers is alleviated, and the adverse factors of safety in working are eliminated.
Description
Technical field
The utility model relates to a kind of automatically-unhooked suspension hook, the automatically-unhooked suspension hook that has automatic decoupling device on particularly being used to drive a vehicle.
Background technology
Consult Fig. 1, present travelling crane hook comprises suspension hook 1, chain 2 and the coupling link 3 that connects described suspension hook 1 and chain 2.Travelling crane hook mainly is to rely on artificial the unhook, and the 3T suspension hook is affiliated on the chain of travelling crane hook, and the chain 2 of travelling crane hook has two, and long one one is fixing, and one has an ellipse iron hoop; Short one one is fixing, and the coupling link 3 with ￠ 24mm is connected with the 3T suspension hook, and point of connection is a fixing active fulcrum.Reel chain is scurried when hanging thing, and the ellipse iron hoop is enclosed within on the 3T hook, when breaking off relations, needs manually hook to be separated with the chain suspension ring, reaches the unhook purpose.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic decoupling device, need rely on manually-operated technical matters when breaking off relations to solve.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of automatically-unhooked suspension hook comprises suspension hook, chain and the coupling link that connects described suspension hook and chain; It is characterized in that described suspension hook also comprises an automatic decoupling device, this automatic decoupling device has a junction, captives joint with described coupling link.
One is extended with a pouring weight on the connecting portion of described automatic decoupling device, and this pouring weight by gravity has a downward application force around described coupling link.
Described pouring weight along it from described connecting portion on sectional area on the one direction of extending increase gradually.
Have an interconnecting gangway between described pouring weight and the connecting portion, this interconnecting gangway along pouring weight from described connecting portion on the one direction of extending sectional area greater than connecting portion along pouring weight from described connecting portion on sectional area on the one direction of extending.
Described pouring weight can be selected the iron stone roller for use.
Use above-mentioned automatically-unhooked suspension hook, after the blockchain bar handling object of being expert at exactly arrived the destination, chain is loosening not to stress, utilize pouring weight from weight, automatically suspension hook is separated with lifted weight, reach the unhook purpose.
In the work of reality was used, automatically-unhooked suspension hook was easy, practical, easy to maintenance, has alleviated working strength of workers, had eliminated safe unfavorable factor in the work.
Description of drawings
Fig. 1 is the scheme drawing of existing travelling crane hook;
Fig. 2 is the scheme drawing of travelling crane hook of the present utility model;
The specific embodiment
Consult Fig. 2 below,, constructional feature of the present utility model is further described in conjunction with a specific embodiment.
A kind of automatically-unhooked suspension hook comprises suspension hook 1, chain 2 and the coupling link 3 that connects described suspension hook 1 and chain 2; Described suspension hook also comprises an automatic decoupling device, and this automatic decoupling device has a weld part 41, adopts welding manner to be fixed together with described coupling link 3.One is extended with iron stone roller 42 on this weld part 41, and this iron is cut or polish jade with an emery wheel 42 by gravitys and had a downward application force around described coupling link 3.Have a sudden change between described iron stone roller 42 and the weld part 41, promptly the sectional area of the iron stone roller 42 on the direction that one is extended from the described weld part 41 greater than weld part 41 along iron stone roller 42 from described weld part 41 on sectional area on the direction of one extension.
Claims (5)
