Description
Technical field
The invention belongs to mechanical field.
Background technology
Being used to link up with the device of disengaging both at home and abroad at present mainly has two kinds of hand and combustion-explosion type：
One, hands；Depart from manually after i.e. hanging weight landing (arriving at), by people by the weight of hanging from hook
On remove, be generally used in crane (straddle truck) lifting, operating efficiency is relatively low.
Two, combustion-explosion types：Current combustion-explosion type is commonly used on helicopter hanger, when helicopter is by hanging object handling to destination
Afterwards, as when being inconvenient to the disengaging mode for using hand, blasting bolt is typically started using pilot and destroys hook structure, will
Hanging object discharges.
The content of the invention
The purpose of the present invention is：
The formula that designs a mechanism links up with release unit, by way of restricting and drawing, the rope that will timely and effectively hang on suspension hook
Rope is separated from.
The technical scheme is that：
A kind of mechanical hook release unit, including：
Link up with (1) head and be provided with pin-and-hole, elastic backing pin (2) head is stretched out from pin-and-hole, hook (1) root and shell (8)
It is hinged, hook (1) can be rotated around shell (8), and catch (3) head is blocked by backing pin (2) head, catch (3) root and hook
(1) root pin joint, and catch (3) root is provided with catch spring (4) between the position at middle part and hook (1) root；Open
Locking device (7) is arranged on shell (8), and the tube head of unlocking apparatus (7) is connected with one end of drawstring (5), and drawstring (5), which is passed through, to be hung
Hook (1) is connected with backing pin (2) root, and the bushing of unlocking apparatus (7) is provided with latch (6)；
Touch tube head after latch (6), unlocking apparatus (7) delay preset time and tense drawstring (5), drawstring (5) retraction is taut
Directly backing pin (2) is retracted in the pin-and-hole of hook, catch (3) loses constraint, rotated in the presence of catch spring (4) around pin, will
(1) is linked up with to open.
Mounting means of the described backing pin (2) on hook (1) is telescopic fashion or rotated versions.
Described backing pin (2) can all be retracted hook (1) under the pulling force effect of drawstring (5) and under the compressing of external force.
Described catch spring (4) is torsion spring or leaf spring.
Described drawstring (5) is cable wire.
Described latch (6) is flexible latch or rigid latch.
The shake-up mode of described latch (6) is hand or turned when hanging weight lands aft hook (1) around shell (8)
Touched naturally when dynamic.
It is an advantage of the invention that：
Compared with hand departs from, timely with easy to use, separation, working environment is not by air-drop weight size and position
Limitation, the low advantage of cost of labor；
Compared with combustion-explosion type blasting bolt, with cost is low, simple and compact for structure, easy to use, performance is stablized, anti-interference
Ability is strong, without potential safety hazard, can Reusability, long lifespan the advantages of.

Embodiment
Embodiment 1：The present invention is described in further details below.As shown in Figure 1, 2,
A kind of mechanical hook release unit, wherein：
1 head is linked up with provided with pin-and-hole, the elastic head of backing pin 2 is stretched out from pin-and-hole, and 1 root of hook is hinged with shell 8, is linked up with
1 can be rotated around shell 8, and the head of catch 3 is blocked by the head of backing pin 2, the root of catch 3 and 1 root pin joint of hook, and catch 3
Root is provided with catch spring 4 between 1 root of position and hook at middle part；Unlocking apparatus 7 is arranged on shell 8, dress of unlocking
The tube head for putting 7 is connected with one end of drawstring 5, and drawstring 5 is connected through hook 1 with the root of backing pin 2, on the bushing of unlocking apparatus 7
Provided with latch 6；
Touch tube head after latch 6, the delay preset time of unlocking apparatus 7 and tense drawstring 5, drawstring 5 bounces back exceptionally straight by backing pin 2
Retract in the pin-and-hole of hook, catch 3 loses constraint, the pivoting in the presence of catch spring 4, hook 1 is opened.
It is telescopic fashion that mounting means of the described backing pin 2 on hook 1, which is,.
Described backing pin 2 can all contract under the pulling force effect of drawstring 5 and under the compressing of external force (rotation of the ecto-entad of catch 3)
Enter hook 1.
Described catch spring 4 is torsion spring.
Described drawstring 5 is cable wire.
Described latch 6 is flexible latch.
The shake-up mode of described latch 6 is hand.
Latch 6 is inserted into unlocking apparatus 7, unlocking apparatus 7 locked with instrument, drawstring 5 is in relaxation state, by hanging object
9 are hung on hook 1, and catch 3 is closed, as shown in Figure 1；Pulled out before hanging after latch 6, unlocking apparatus 7 is pre- in delay
Put and worked after the time, drawstring 5 is tensed, because hanging weight 9 weight is more than the pulling force of unlocking apparatus 7, catch 3 will not be opened,
After hanging weight 9 lands and (arrived at), hook 1 is in relaxed state, and the pulling force of unlocking apparatus 7 is restricted more than hanging object 9
The weight of rope, catch 3 is opened, and the rope of hanging object 9 is separated from by drawstring 5 with hook 1, as shown in Figure 2.
