Work boat hook assembly

Abstract

The invention relates to a work boat hook assembly which comprises a remote control platform, a pull pin control handle, a brake block control handle, a stop rod and fixing pin, a bow pull pin controlflexible shaft, a stern pull pin control flexible shaft, a bow brake block control flexible shaft, a stern brake block control flexible shaft, a bow pull pin, a stern pull pin, a bow lever force arm,a stern lever force arm, a bow pull rod, a stern pull rod, a bow brake block and external unhooking pedal, a stern brake block and external unhooking pedal, a bow rope stop frame and bolt, a stern rope stop frame and bolt, a bow green locking mark, a stern green locking mark, a bow hook head, a stern hook head, a bow hook shaft, a stern hook shaft, a bow connecting pin, a stern connecting pin, abow brake block shaft, a stern brake block shaft, a bow safety pin and a stern safety pin. Under a normal working condition, remote control mode operation is adopted, when a fault occurs to a remote control operation system, the operation mode can be replaced with a pedal mode or a manual operation mode in time, and therefore operation that a work boat can be smoothly released to the sea surface or recovered back into a mother vessel can be guaranteed no matter the remote control system works normally or not.

Description

technical field [0001] The invention relates to a hook device, in particular to a working boat hook device. Background technique [0002] There are two traditional types of working boat hook device, one is pedal type working boat hook device, which is mainly composed of fixed hook plate A01, protection pin and pedal A02, and return spring A03 (see attached figure 1 ), the opening and closing between the protection pin and the fixed hook plate A01 can be controlled by stepping on the protection pin and the pedal A02 and the return spring A03 below it. This type of hook device is used for single lifting point working boats It is more convenient to use when using it, but when it is applied to the working boat with double hoisting points, it needs more people to participate in the operation synchronously, the synchronous decoupling cannot be guaranteed during the release process, it does not have the function of on-load release, and the type of supporting davit is limited.

[0002] There are two traditional types of working boat hook device, one is pedal type working boat hook device, which is mainly composed of fixed hook plate A01, protection pin and pedal A02, and return spring A03 (see attached figure 1 ), the opening and closing between the protection pin and the fixed hook plate A01 can be controlled by stepping on the protection pin and the pedal A02 and the return spring A03 below it. This type of hook device is used for single lifting point working boats It is more convenient to use when using it, but when it is applied to the work boat with double hoisting points, there are more people who need to participate in the operation synchronously, the synchronous decoupling cannot be guaranteed during the release process, the on-load release function is not available, and the supporting davit type is limited, etc.

[0003] The other is the remote-controlled working boat hook device, which controls the telescopic movement of the flexible shaft core through the operation of the corresponding handle of the control box by the operator, and then controls the opening (release) and closing (connection) of the hook of the hook device. Although the working boat hook device avoids the defects in the use of the foot-operated working boat hook device, when the flexible shaft fails, the release system will not work

[0004] To sum up, the remote-controlled working boat hook device is better than the pedal-operated working boat hook device, but both of the above two working boat hook devices have more application limitations, and there is no emergency response function in case of failure
