Problems solved by technology

However, since the boat hook is based on a spherical bearing body, theoretically there is a point contact between the insertion rod ring groove and the bearing steel sphere, and the local stress is relatively large, although the stress on each sphere can be dispersed by increasing the diameter of the bearing sphere and the number of distributions , but the carrying capacity is limited without increasing the size of the carrying sphere

Embodiment Construction

[0021] Below, the technical solution of the present invention will be further specifically described by using the boat hook used for lifeboats as an embodiment of the present invention and in conjunction with the accompanying drawings.

[0022] figure 1 It is a sectional view through the centerline of the present invention, and the figure shows the state when the plunger 12 is not inserted. Since the device is based on the structure of a revolving body, the sectional view through the centerline can show all the components, including: outer casing 1, locking sleeve 2, Bearing block 3, sliding sleeve 4, linear bearing 5, rib 6, compression spring 7, mounting seat 8, connecting rod 9, protective cover 10, pull ring 11. In the illustration, the inner hole of the casing 1 is composed of a large counterbore with a longer depth, a shorter small counterbore and a smaller through hole from bottom to top. The large counterbore of 1 is matched with the short convex outer cylindrical sur...

Abstract

The invention provides a plug-in rescue boat hook device with a heavy load unhooking function. The conventional open hook-on boat hook structure mode is broken through; a boat hook body is of a revolved body fully enclosed structure; a boat hook with a cylindrical plug rod shrunk into a double-cone annular groove for plug-in hanging is adopted; a plurality of lockable variable rectangular blocks are utilized; and a spring is used for preventing loosening and realizing resetting and protection. The device has the characteristics of high bearing capacity, short unhooking travel, reliable unhooking, corrosion resistance and convenience in maintenance.

Description

technical field [0001] The invention relates to a boat hook device, in particular to a boat hook device for a plug-in lifeboat with a heavy-duty decoupling function. Background technique [0002] The traditional lifeboat hook is based on the traditional open hook design for lifting. By pinning the hook upside down and connecting it to the hook body, the ring connected to the spreader on the ship is hooked with the hook before the lifeboat is lowered. Due to the open type Due to the inherent limitations of the hook structure, the ring needs to be hooked from the opening when connecting, and the ring should be disengaged from the opening when the hook is rotated. In order to prevent accidental decoupling of the lifeboat hook during hoisting of the lifeboat, an anti-detachment mechanism needs to be installed to block the exit of the hook. When the waves cause the large ship to shake at a large angle, it is easy to cause accidental decoupling of the lifeboat hook midway, causin...
