Description

The self lighting type Jack

Technical field: the utility model relates to a kind of hoisting device, relates in particular to a kind of hoisting device that heat treated part is come out of the stove that is used to lift by crane.

Background technology: at present, when high temperature objects such as lifting foundry goods or heat treated part, adopt the hook type hoisting device usually.Though its structure is fairly simple, hook, the manually closely operation of breaking off relations; Not only there are operating time length, troublesome poeration, low, the safe differential of efficient, but also influence thermal treatment quality.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of easy and safe to operate, efficient is high, thermal treatment quality is good self lighting type Jack.

To achieve these goals, the utility model is by the following technical solutions: it comprise hanger, with this hanger pivotally attached gib; The center of gib is provided with through hole, and the epimere of this gib, stage casing and hypomere are respectively equipped with first square hole, second square hole and third party hole, and the lock that has catch gear is erected in first square hole, is located at slide bar in the through hole and passes the lock frame and protrude upward; Be respectively equipped with first spring and second spring that are enclosed within on the slide bar in first square hole and second square hole, be provided with in the third party hole that an end is hinged on the slide bar jointly, the other end respectively with two connecting rods of two bearing plate pivotallys attached, the other end of bearing plate is hinged on the gib jointly; Described catch gear is by being located at the dead bolt of lock on the frame, being enclosed within the 3rd spring on this dead bolt, constituting with this dead bolt pivotally attached handle, and the stationkeeping corresponding to the lock frame on gib has lock ring.

The hole wall of through hole is provided with guide groove, is fixed with the feather key adaptive with this guide groove on slide bar; On the lock frame, be fixed with guard shield, in second square hole, be fixed with two cleadings; Be fixed with the guiding awl in the lower end of gib.

Compared with the prior art, the utility model has been owing to adopted technique scheme, therefore only needs to be provided with one and can carry out automatic hitch lifting and remote unhook to it very easily with the roughly the same hole of gib diameter on charging basket that is used for the splendid attire workpiece or charging tray; Not only convenient to operation, efficient is high, but also eliminated the hidden danger of manually closely operating and bringing.
