Abstract

The utility model relates to a lifeboat releasing hook which comprises a lifting hook plate, a lifting hook, a stop lever, a guy cable and a rotating shaft, wherein the lifting hook is mounted on the lifting hook plate through the rotating shaft, one end of the stop lever is mounted on the lifting hook plate through the rotating shaft, the other end of the stop lever is connected with the guy cable through the rotating shaft, and the stop lever is mounted at the lower end of the lifting hook and clips the lower end of the lifting hook; and the lifeboat releasing hook is characterized in that a shielding shaft through hole is formed on the lifting hook plate in front of the lower end of the lifting hook, which is clipped by the stop lever, and an L-shaped shielding shaft is inserted into the shielding shaft through hole. The utility model has the advantages that the accident releasing of a lifeboat can be effectively prevented when maintenance is performed on the lifeboat.

Description

A kind of life boat release hook

Technical field

The utility model relates to a kind of release hook, relates in particular to a kind of life boat release hook.

Background technology

At present, the life boat release hook comprises suspension hook plate, suspension hook, pin, drag-line and rotating shaft, and suspension hook is installed on the suspension hook plate through rotating shaft, and pin one end is installed on the suspension hook plate through rotating shaft, and the pin other end is connected with drag-line through rotating shaft, and pin is installed in the suspension hook lower end; Thereby driving pin through the pulling drag-line opens with the life boat release of playing suspension hook; Because the release hook of life boat all need be safeguarded every year; Most life boat release hooks is through on the suspension hook plate, increasing auxiliary boatswain chair when safeguarding; Through auxiliary boatswain chair release hook is sling by steel rope and turnbuckle with lifting appliance, thereby the operating system of suspension hook is safeguarded and keeped in repair; Lift here on the equipment auxiliary eye plate must with the auxiliary boatswain chair of life boat on a vertical curve, otherwise can cause suspension hook to bear side force, thereby the life boat release hook is discharged life boat is unexpected; Simultaneously life boat is being carried out full outboard when safeguarding or safeguarding, the service personnel in life boat is if touch drag-line unintentionally, also possibly discharge life boat is unexpected, thus the service personnel in life boat and the life boat damaged.

Summary of the invention

To above-mentioned shortcoming, the utility model purpose is to provide a kind of and when life boat is safeguarded, can prevents the unexpected life boat release hook that discharges of life boat.

The technology contents of the utility model is: a kind of life boat release hook; Comprise suspension hook plate, suspension hook, pin, drag-line and rotating shaft; Suspension hook is installed on the suspension hook plate through rotating shaft; Pin one end is installed on the suspension hook plate through rotating shaft, and the pin other end is connected with drag-line through rotating shaft, and pin is installed in the suspension hook lower end and fastens the suspension hook lower end; It is characterized in that on pin fastens the suspension hook plate of front upper place of suspension hook lower end, being provided with a gear shaft through hole, in the gear shaft through hole, be inserted with a L shaped gear shaft.

For prevent that L shaped gear shaft from coming off from the gear shaft through hole, on L shaped gear shaft, be provided with a protrusion, corresponding level attitude at the gear shaft through hole is provided with a recess; After L shaped gear shaft passed, L shaped gear shaft was because 90 degree are rotated in the deadweight effect, and then protrusion can prevent the gear shaft slippage.

The advantage that is compared with prior art had of the utility model is: can prevent thus the unexpected release of life boat through when keeping in repair, before suspension hook, placing a L shaped gear shaft.
