Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figures 1-4, the present invention includes main body frame 1, suspension hook 2, block 3, self-locking connecting rod 4, spring 5, unhook knob
6 and break off relations rope 7, wherein suspension hook 2 is hinged on the lower end of the main body frame 1 by suspension hook shaft 11, in the main body frame 1
Equipped with block 3 and self-locking connecting rod 4, the block 3 is hinged on 1 middle part of main body frame by block shaft 10, as shown in Fig. 2, working as
When mechanism is in the lock state, the block 3 offsets to lock suspension hook 2 with 2 afterbody of suspension hook, and the knob 6 that breaks off relations passes through knob
Shaft 8 is hinged on the upper end of the main body frame 1, and the knob 6 that breaks off relations is triangular in shape, in 6 three ends of knob of breaking off relations
One end be mounted in the knob shaft 8, one end is arranged at that the main body frame 1 is outer 7 to be connected with breaking off relations to restrict, and is equipped at the end
For the circular hole of the fixed rope 7 that breaks off relations, one end is arranged in the main body frame 1 and by the self-locking connecting rod 4 and the block 3
It is connected, as shown in Fig. 2, when mechanism is in the lock state, the self-locking connecting rod 4 is in same straight line with the knob shaft 8
On, so as to formed mechanical dead point make block 3 can not rotation lock suspension hook 2, in main body frame 1, away from it is described break off relations shake hands 6
One side is equipped with spring 5, and one end of the spring 5 is fixed on main body frame 1, the middle part phase of the other end and the self-locking connecting rod 4
Even, when mechanism is in the lock state, the spring 5 is in tensional state, and so just applying one to self-locking connecting rod 4 stretches in advance
Clamp force, anti-stop block 3 rotate counterclockwise, and unhook knob 6, self-locking connecting rod 4 and block 3 is made to ensure to hang always in dead point state
2 reliable lock of hook.
As shown in figures 2-3, support plate 9 is equipped in the one side of the main body frame 1, the support plate 9 is equipped with pilot hole, institute
It states after the rope 7 that breaks off relations passes through the pilot hole on the support plate 9 and is connected with the knob 6 that breaks off relations, when automatic unhooking function to be realized,
Manually pull the rope 7 that breaks off relations that the knob 6 that breaks off relations is driven to rotate, when manpower overcomes 5 pulling force of spring, the knob 6 that breaks off relations,
Self-locking connecting rod 4 and block 3 just depart from mechanical dead-centre position, and the unlock of suspension hook 2 can be freely rotated, when lock-out state to be recovered,
The rope 7 that breaks off relations is unclamped, it is dead that break off relations knob 6, self-locking connecting rod 4 and block 3 are restored to original machinery under 5 pulling force effect of spring
Point position.
The present invention operation principle be：
Lifting process：
When needing to lift by crane article, lift unhook knob 6 manually, unhook knob 6, self-locking connecting rod 4 and block 3 is made to depart from machinery
Dead-centre position, at this time suspension hook 2 unlock, can be freely rotated；After suspension hook 2 rotates clockwise, by hanging for the article lifted by crane
Point (such as hanging ring, shackle, rope) is inserted in 2 inner ring of suspension hook, and suspension hook 2 is rotated counterclockwise to the position of locking state, release
Break off relations knob 6, using 5 pulling force of spring unhook knob 6, self-locking connecting rod 4 and block 3 is made to reach the locked position at mechanical dead point, this
When automatic decoupling device mounting finish, lifting operation can be carried out.
Unhook process：
When needing release lifting article, the rope 7 that breaks off relations is pulled by manpower, unhook knob is made 6 to be lifted up, when manpower can be with
When overcoming the pulling force of spring 5, break off relations knob 6, self-locking connecting rod 4 and block 3 depart from mechanical dead-centre position, and 2 automatic unlocking of suspension hook is hung
Hook 2 can be freely rotated, and the effect that suspension hook 2 relies on lifted weight self gravitation at this time rotationally clockwise, has realized lift heavy
The unhook of object.
