Corresponding with the opening of gate connection frame, the outer end face of nylon cylinder is equipped with stern transom plate, the nylon cylinder by lock-screw
Inside pin shaft is installed, the rear end of the pin shaft is extended with guide pad, and the outer circumference surface of the guide pad is the guiding conical surface, institute
It states and pressure spring is installed between guide pad and stern transom plate；The outside wall surface of the nylon cylinder is also provided with right angle hole, in the right angle hole
Handle is installed, is threadedly coupled between the handle and pin shaft.
Its further technical solution is:
The bearing head is machining integral structure, and end is threaded, by circular hole above gate connection frame, is screwed in tight
Gu in the threaded hole of square nut.
The end of the handle is threaded, screws in the threaded hole of pin shaft.
The guide pad is an integral structure with pin shaft, and the center of guide pad is hollow.
Beneficial effects of the present invention are as follows:
Structure of the invention is compact, reasonable, easy to operate, is designed on the heavy basis for playing hoisting shackle, has knot
Structure is simple and convenient to operate, practicability and the features such as high reliablity, and effective solution is under complicated severe sea condition, monolithic lifting lug
Submersible personnel link up with the difficult problem that breaks off relations, using the present invention, operator can complete to break off relations in a short period of time
With hook operation, risk caused by hook unhook operation is greatly reduced, thus the sound assurance people of operating personnel
Body safety.The present invention is applicable not only to submersible sea lifting operation, is equally also suitable for the lifting operation of land normal goods
Operating condition can reduce lifting spent time, to improve production efficiency to a certain extent.
