Abstract
The present invention discloses a kind of safety hook, it is desirable to provide one kind can prevent that steel wire rope from breaking off relations, and easy to operate lifting suspension hook.It includes pulley, framework, suspension hook, bearing outer ring, bearing inner race, bearing inner sleeve, connecting rod, locking bar.Bearing inner sleeve lower end is stretched out outside framework, and it is interference fitted with bearing inner race and kink is in suspension hook shank；Bearing outer ring is fixed with framework, and one end and the bearing inner sleeve of connecting rod are hinged, and one end of the other end and locking bar is hinged, and the middle part of the locking bar is hinged with the suspension hook.During lifting, frame strip dynamic bearing, bearing inner sleeve are moved up along suspension hook shank, and connecting rod is also moved up therewith, and the locking bar being hinged therewith is rotated around the pin joint of locking bar and suspension hook, locking bar is fastened suspension hook；When putting down lifting object to ground, frame strip dynamic bearing, bearing inner sleeve are moved down along suspension hook shank, and connecting rod is moved down therewith, are driven locking bar to be rotated around locking bar and suspension hook pin joint, are unclamped the suspension hook of fastening, put down steel wire rope.The present invention is available for the suspension hook on the lifting appliances such as loop wheel machine, crane.
Description
Technical field
The present invention relates to a kind of lifting suspension hook.
Background technology
Lifting suspension hook, mostly without the device for preventing that steel wire rope from breaking off relations, during lifting, Yi Fashengyin, which breaks off relations, causes security incident
Or article is damaged.
The content of the invention
The present invention overcomes the above-mentioned deficiency of prior art to prevent that steel wire rope from breaking off relations there is provided one kind, and easy to operate hangs
Dress suspension hook.
The present invention is adopted the following technical scheme that：A kind of safety hook, by pulley, framework, suspension hook, bearing outer ring, bearing
Circle, bearing inner sleeve, connecting rod, locking bar composition.Bearing inner sleeve and bearing inner race are interference fitted, and kink is in suspension hook shank, under it
End is stretched out outside framework, is hinged with one end of connecting rod；The other end of connecting rod and one end of locking bar are hinged, and the middle part of locking bar is with hanging
Hook is hinged；Bearing outer ring is fixed on framework, and the axle of pulley is also secured on framework.
During lifting, pulley driving framework, the bearing outer ring on framework drives bearing inner race, bearing inner sleeve along along suspension hook shank
Move, connecting rod is also moved up therewith, the locking bar being hinged therewith is rotated around the hinged place of locking bar and suspension hook, locking bar is fastened suspension hook；When
When putting down article to the ground of lifting, frame strip moving axis bearing outer-ring, bearing inner race, bearing inner sleeve are moved down along suspension hook shank, connection
Bar is moved down therewith, is driven locking bar to be rotated around the pin joint of locking bar and suspension hook, is unclamped the suspension hook of fastening, steel wire rope is disengaged suspension hook.
The beneficial effects of the invention are as follows effectively prevent that steel wire rope departs from suspension hook during operation, it is ensured that ground staff's safety, prevents
Lifting article is damaged because of unhook.
Brief description of the drawings
Accompanying drawing is the schematic diagram of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description：
The axle of pulley 1 is fixed on framework 7, and the outer ring of bearing 6 is also secured on framework 7；The kink of bearing inner sleeve 3 is in suspension hook
2 shank, the lower end of bearing inner sleeve 3 is stretched out at framework 7, is hinged with one end of connecting rod 4, the other end and the locking bar 5 of connecting rod 4
One end be hinged, middle part and the suspension hook 2 of locking bar 5 are hinged.
When loop wheel machine pulls pulley 1, when driving the shank along suspension hook 2 of framework 7, bearing 6 to move up lifting, connecting rod 4 is also therewith
Move up, the locking bar 5 being hinged with connecting rod 4 is rotated around with the pin joint of suspension hook 2, when bearing 6 encounters the top dead centre of the shank of suspension hook 2,
Stopping is moved up along the shank of suspension hook 2, and locking bar 5 just fastens suspension hook 2.
When putting down article to the ground of lifting, shank of the bearing 6 together with framework 7 along suspension hook 2 is moved down, and is made through connecting rod 4
Locking bar 5 opens the suspension hook 2 of fastening, so that steel wire rope disengages suspension hook 2.
