Abstract

The utility model relates to a lifting hook device of a rescue boat, which is characterized in that the lifting hook device of the rescue boat comprises a lifting hook frame fixedly connected on a boat body; the lifting hook is arranged on the lifting hook frame through a pin shaft; one end of a brake block is hinged on the lifting hook frame below the pin shaft; the other end of the brake block is connected with an operation handle; a positioning groove is arranged on the brake block; a fixed pin hole is arranged on the lifting hook frame which is arranged below the brake block; and when the lifting hook is in a hoisting position, the fixed pin is inserted into the fixed pin hole, the brake block abuts against the fixed pin, the tail end of the lifting hook is locked in the positioning groove of the brake block, and a gravity position of the lifting hook deviates from the position of the axial line of the pin shaft. The lifting hook device has a simple structure, is convenient to operate and is labor-saving; and through using the gravity of the lifting hook and the axial line deviating from the lifting hook pin shaft, the lifting hook can be automatically turned over to release steel cables to lighten the work intensity of the boatmen when the steel cables are released, so that the security of the boatmen is guaranteed when the steel cables are released, and the damage to the boatmen can be avoided.

Description

The rescue craft cargo hook gear

Technical field

The utility model relates to jolly boat or the lifting hook device of relief on a kind of large ship.

Background technology

Rescue craft or jolly boat are arranged on the boat hoist platform of large ship usually, and boat hoist is implemented the lifting of ship and transferred operation through the suspension hook of boat fall, leading sheave group, suspension ring connection life boat.In the prior art, after rescue craft or jolly boat were hung oneself on the sea from large ship, the crewman needed manual the unhook, effort not only, and have potential safety hazard, the crewman is damaged.

The utility model content

The applicant has carried out research and has improved to above-mentioned problem, and a kind of rescue craft cargo hook gear is provided, and solving the crewman needs the manual problem that breaks off relations, and alleviates crewman's working strength, avoids the crewman is damaged.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of rescue craft cargo hook gear; Comprise the suspension hook frame that is fixedly connected on the hull, suspension hook is installed on the said suspension hook frame through bearing pin, and an end of slipper is hinged on the suspension hook frame of said bearing pin below; The other end attended operation handle of slipper, slipper is provided with positioning groove; The suspension hook frame of said slipper below is provided with fixed pin holes; When suspension hook lift heavy position, set pin is inserted in the said fixed pin holes, and said slipper is resisted against on the set pin; The tail end of said suspension hook is locked in the positioning groove of said slipper, and the center-of-gravity position of suspension hook departs from the axial location of bearing pin.

Further:

Said suspension hook frame is provided with only rope frame, the said front end that ends the spacing said suspension hook in upper end of rope frame.

Said suspension hook frame comprises substrate, and the support plate of arranging that takes the shape of the letter U is arranged on the said substrate, and the top of said support plate is provided with strut bar.

The technique effect of the utility model is:

The disclosed a kind of rescue craft cargo hook gear of the utility model, simple in structure, easy to operate; Utilize suspension hook center of gravity and the axis that departs from the suspension hook bearing pin; When discharging wirerope, suspension hook overturns automatically and discharges wirerope, alleviates crewman's working strength; Guarantee the safety of crewman when discharging wirerope, avoid the crewman is damaged.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.

Shown in Fig. 1～5, the utility model comprises the suspension hook frame 1 that is fixedly connected on the hull, and suspension hook frame 1 comprises that 101, three support plates 102 of substrate take the shape of the letter U and arranges and be welded on (like Fig. 5) on the substrate 101 that the top of support plate 102 is provided with strut bar 103.Suspension hook 2 is installed on the suspension hook frame 1 through bearing pin 3, and suspension hook frame 1 is provided with only rope frame 8, ends the front end of the spacing suspension hook 2 in upper end of rope frame 8, ends rope frame 8 and can prevent that wirerope from skidding off from suspension hook 2.One end of slipper 4 is hinged on through bearing pin 6 on the suspension hook frame 1 of bearing pin 3 belows, the other end attended operation handle 5 of slipper 4, and slipper 4 is provided with positioning groove 401; The suspension hook frame 1 of slipper 4 belows is provided with fixed pin holes; When suspension hook lift heavy position, set pin 7 is inserted in the fixed pin holes, and slipper 4 is resisted against on the set pin 7; The tail end of suspension hook 2 is locked in the positioning groove 401 of slipper 4, the axial location of the center of gravity line position deviation bearing pin 3 of suspension hook 2.

When rescue craft arrives on the sea, when needing to break off relations, set pin 7 is extracted; Downward pull operation handle 5; Make the tail end of suspension hook 2 break away from the positioning groove 401 of slipper 4, because the center-of-gravity position of suspension hook 2 departs from the axial location of bearing pin 3, suspension hook 2 is overturn by action of gravity automatically; Wirerope is released, and rescue craft can go at the water surface.When suspension hook 2 resetted, pull operation handle 5 was locked in the positioning groove 401 of slipper 4 tail end of suspension hook 2, and set pin 7 is inserted in the fixed pin holes, and set pin 7 makes the tail end positive lock of suspension hook 2.
