Description
Technical field
It the utility model is related to the technical field of crane, and in particular to a kind of crane Anti-hook releasing device.
Background technology
Crane applications are extensive, and facility is provided to industries such as construction buildings.Goods is caught on and hung by suspension hook by crane
Rise, but in the engineering of crane work, due to extraneous factors such as wind, cause the steel wire rope of crane to rock, so hold very much
Easily there is the phenomenon to break off relations, cause casualties, the adverse consequences such as cargo damage.
At present, the Anti-hook releasing device overwhelming majority of crane hook is that the anti-drop device of duck tongue type is fabricated to using steel plate,
The duck tongue shape steel plate is fixed on to the neck of suspension hook using Spring Card and micro screw.When in use, rigging can be directly sleeved on suspension hook
On, duck tongue type Anti-hook releasing device is under the Action of Gravity Field of rigging, using micro screw as axis of rotation, is opened together with suspension hook formation
Mouthful, rigging enters the mouth of hook, and duck tongue type Anti-hook releasing device forms with suspension hook and closed, prevent rigging from existing in the presence of spring force
Run out of during use, but need operating personnel to pin steel plate using thumb during steel wire rope abjection, rigging takes out from suspension hook mouth, behaviour
It is inconvenient to make, and easy tong.
Utility model content
The purpose of this utility model is：A kind of crane Anti-hook releasing device, simple in construction, fixation, behaviour are provided
Facilitate, prevent tong.
The technical scheme that the utility model is taken is：
A kind of crane Anti-hook releasing device, including suspension rod and suspension hook, suspension rod and suspension hook are integrated, in the free end of suspension hook
Curved rod is hinged with, hook is hinged with the free end of curved rod, square opening is provided with suspension rod, it is fixed in square opening
There is the connecting shaft set along suspension rod bearing of trend, be provided with connecting hole in connecting shaft, connecting hole is angling hole, the center of connecting hole
The scope of the angle α of line and the center line of connecting shaft is 55 ° -60 °, and the connecting hole on hook and connecting shaft on curved rod is matched somebody with somebody
Close.
Several grooves are provided with the inner side of suspension hook.
Skid resistant course is provided with connecting hole.
When the connecting hole of hook and connecting shaft on curved rod coordinates, the opening direction of curved rod and the opening of suspension hook
In the opposite direction.
The utility model is simple in construction, in the connecting hole in hook insertion connecting shaft on curved rod, fixation, and behaviour
Facilitate, prevent tong；Connecting hole is angling hole, is conveniently inserted a hook into connecting hole；Set on the concave profile of suspension hook
There are several grooves, when weak vibrations occur for suspension hook, groove can tentatively prevent that suspender from leaping up out suspension hook；Skid resistant course can increase extension
The frictional force of hook and connecting hole.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model；
Fig. 3 is partial enlarged drawing at A in Fig. 2.
Embodiment
As depicted in figs. 1 and 2, a kind of crane Anti-hook releasing device, including suspension rod 1 and suspension hook 2, suspension rod 1 and suspension hook 2 are
One, is hinged with curved rod 3 in the free end of suspension hook 2, hook 4 is hinged with the free end of curved rod 3, on suspension rod 1
Provided with square opening 101, the connecting shaft 5 set along the bearing of trend of suspension rod 1 is fixed with square opening 101, is provided with connecting shaft 5
Connecting hole 501, the hook 4 on curved rod 3 coordinate with the connecting hole 501 in connecting shaft 5, axis and the suspension rod 1 of connecting shaft 5
It is axially in parallel, can effectively prevent hook from 4 being leapt up out out of connecting hole 501 during lifting.
As shown in figure 3, the angling hole of connecting hole 501, the incline direction of angling hole is downward, and the center line of connecting hole 501 exists
The counter clockwise direction of the center line of connecting shaft 5, and the model of the center line of connecting hole 501 and the angle α of the center line of connecting shaft 5
It is 55 ° -60 ° to enclose, convenient that hook 4 is inserted into connecting hole 501.
Several grooves 201 are provided with the inner side of suspension hook 2, the inner side of suspension hook 2 refers to the side of the opening direction of suspension hook 2,
Suspender is suspended on the inner side of suspension hook 2, and when weak vibrations occur for suspension hook 2, suspender moves between groove 201, and groove 201 can be first
Step prevents that suspender from leaping up out suspension hook 2.
Skid resistant course 6 is provided with connecting hole 501, skid resistant course 6 is made up of anti-slip material, such as on-slip abrasive band, the energy of skid resistant course 6
The frictional force of enough increase hooks 4 and connecting hole 501 so that hook 4 coordinates closer with connecting hole 501.
When hook 4 and the connecting hole 501 of connecting shaft 5 on curved rod 3 coordinate, the opening direction of curved rod 3 is with hanging
The opening direction of hook 2 is opposite.
When in use, after suspender being suspended into suspension hook 2, curved rod 3 is rotated, by the company of being inserted into of hook 4 on curved rod 3
In connecting hole 501 in spindle 5, so during lifting can effective anti-locking hook, it is easy to operate, prevent tong.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
