Specific embodiment
Hereinafter, the present invention is further described with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of underwater automatic disengagement hook that the embodiment of the present invention provides, including：Platform sling 1, drive rod 2,
Drive rod shaft 3, unhook swing rod 4, spring 5, hook mounting base 6, hook shaft 7, hook 8.
Underwater automatic disengage connects hanger rope 9 on hook, lower section hanging needs the equipment 10 laid.The top of platform sling 1 is provided with
The mounting hole of hanger rope 9, the lower part hold-down hook mounting base 6 of platform sling 1.
On platform sling 1, between the position of mounting hole and the position of hook mounting base 6, it is additionally provided with drive rod shaft 3.It drives
2 one end of lever is carried by drive rod shaft 3, and can be rotated around drive rod shaft 3；One end of 2 other end of drive rod and spring 5
Connection, the other end of spring 5 are fixed on platform sling 1, and spring 5 applies drive rod 2 downward pulling force.One end of unhook swing rod 4
It is fixedly connected, and can be rotated around drive rod shaft 3 with drive rod 2 with drive rod 2；In the other end of unhook swing rod 4, setting
The insertion hole of hook 8.Hook 8 is " V " shape structure, and the angle between two side arms of " V " shape structure can be 130 degree, hook 8 one
End is installed in rotation on hook mounting base 6, and the other end coordinates with unhook swing rod 4.When hook 8 is inserted into the insertion hole of unhook swing rod 4,
The inner surface of the carrying hook 8 to insert in the hole of unhook swing rod 4 has angle, and can be set as 52 ± 0.1 with horizontal plane
Degree.
As shown in Figure 1, after lifting appliance 10 because suspension needs the equipment 10 laid on hook 8, hook 8 for
Unhook swing rod 4 is applied with enough power, and unhook swing rod 4 cannot be swung, so as to ensure laying for equipment 10.
As shown in Fig. 2, after the equipment 10 for needing to lay reaches the bottom, spring 5 applies drive rod 2 downward drawing
Power so that unhook swing rod 4 rotates up, and equipment 10 will not apply pressure for hook 8 again at this time, and hook 8 is for unhook swing rod 4
The insufficient pressure of application is to limit the movement of unhook swing rod 4, and therefore, unhook swing rod 4 and hook 8 detach.
Platform sling 1 is fixedly connected with hook mounting base 6, constitutes the entire underwater automatic pedestal for disengaging hook device, the pedestal
It can be integrally formed.Drive rod 2 is fixedly connected with unhook swing rod 4, forms unhook component, which can also be integrally formed.
The underwater automatic hook device that disengages can be good at laying equipment suitable for 20t ranks.
Fig. 3 is the structure diagram of the platform sling in Fig. 1.The mounting hole of hanger rope 9 is located at the top of platform sling 1, hook mounting base 6
In the lower left position of platform sling 1 so that the mounting hole of stress point and hanger rope 9 that hook 8 bears to lay equipment 10 bears hanger rope 9
Stress point is on same vertical line.
Fig. 4 is the structure diagram of the drive rod in Fig. 1.Drive rod 2 belongs to non-stress part, therefore, could be provided as
" P " shape structure.
Fig. 5 is the structure diagram of the drive rod shaft in Fig. 1.Axis bottom is the increased boss of radius, increases the strong of axis
Degree, top can have slot.
Fig. 6 is the structure diagram of the unhook swing rod in Fig. 1.In the case of proof strength, hook 8 in unhook swing rod 4
Insertion hole it is big as far as possible.Fig. 6 shows a case that be open until 3 side of drive rod shaft, and this saves making for material
With.
Fig. 7 is the structure diagram of the hook mounting base in Fig. 1.Hook mounting base 6 is welded as a whole with platform sling 1.
Fig. 8 is the structure diagram of the hook in Fig. 1.Angle between two side arms of " V " shape structure of hook 8 can be
130 degree, the surface that hook 8 is contacted with the insertion hole of unhook swing rod 4 is set as 52 degree.
The present invention can be used for cloth being needed to be put into the very big bottom of depth, a kind of underwater automatic disengagement some underwater equipments
After underwater equipment cloth is put into the bottom by hook, it can be disengaged automatically with underwater equipment.It is underwater automatic disengage hook can Reusability, and can hold
By 20t lift heavys.A release load hawser can be saved by laying every time, be greatly saved and laid cost.
