Description

Lifeboat simulated release device

Technical Field

The utility model relates to a lifeboat simulated release device, in particular to a lifeboat simulated release device on an ocean-going vessel.

Background

At present, lifeboats are assembled on ocean-going vessels, in order to detect the safety and reliability of the lifeboats when the lifeboats are released from the ocean-going vessels to the sea, the lifeboats are firstly subjected to simulated release detection, the conventional lifeboat simulated release test is to arrange a lifeboat fixing frame beside a pool, then the lifeboats are simulated and fixed on the lifeboat fixing frame by steel wires, and then the lifeboats are released into the pool from the lifeboat fixing frame to be tested, because the lifeboats are lifted from the ocean-going vessels to the sea surface and swing up and down and left and right along with the fluctuation of the sea surface when the ocean-going vessels are operated at the sea, the lifted lifeboats are pushed by the sea waves, and lifting hooks on the lifeboats can be subjected to the tensile force of the steel wire ropes in all directions, when the simulated release of the lifting hooks on the lifeboats is required to be subjected to the ultimate tensile force in all directions, whether the lifting hooks can be separated from the steel wire ropes in advance or not, or whether the lifting hooks can be damaged and can not be separated from the steel wire ropes normally, the existing lifeboat fixing frame can not realize the detection of the tension of the lifting hook in all directions of the steel wire rope when the lifeboat is released in a multi-posture simulation mode.

Disclosure of Invention

In view of the above disadvantages, the present invention provides a lifeboat simulated release device capable of detecting the tension of a hook on a wire rope in each direction when the lifeboat is subjected to multi-posture simulated release.

The utility model relates to a lifeboat simulated release device, which is characterized by comprising an underframe, an inverted U-shaped swing arm, a rotating shaft, an inner sleeve, an outer sleeve, a steel rope buckle, a plate type rotating shaft seat and a swing arm fixing plate, wherein the rotating shaft is arranged on the inner sleeve; the upper ends of two sides of the underframe are provided with plate-type rotating shaft seats, the rotating shaft is arranged on the plate-type rotating shaft seats, the inner sleeve is arranged outside the rotating shaft, the outer sleeve is rotationally arranged outside the inner sleeve, the two inverted U-shaped swing arms are respectively arranged on two sides of the underframe, and the lower ends of the inverted U-shaped swing arms are fixedly connected with the outer sleeve; a plurality of steel rope buckles are arranged on the inner side of the upper end of the inverted U-shaped swing arm; the swing arm fixed plate sets up on the chassis of the shape of falling U swing arm and overcoat junction, and swing arm fixed plate upper end is the arc, is provided with a plurality of bolt holes in swing arm fixed plate upper end arc department, is equipped with a fixed orifices that can correspond with each bolt hole on the shape of falling U swing arm.

Compared with the prior art, the utility model has the advantages that: the utility model can simulate the tension of a lifting hook on a lifeboat in different boat width directions by the steel wire rope through the steel wire rope buckles fixed at different positions on the inner side of the upper end of the inverted U-shaped swing arm, and can simulate the stress of the lifting hook on the lifeboat in different captain directions by the steel wire rope through the rotation of the inverted U-shaped swing arm, thereby being capable of detecting the tension of the lifting hook in all directions of the steel wire rope when the lifeboat is released in a multi-posture simulation mode.

Detailed Description

As shown in fig. 1, 2, 3 and 4, a lifeboat simulated release device is characterized by comprising an underframe 1, an inverted U-shaped swing arm 2, a rotating shaft 3, an inner sleeve 4, an outer sleeve 5, a steel rope buckle 6, a plate-type rotating shaft seat 7 and an arc-shaped swing arm fixing plate 8;

a plate-type rotating shaft seat 7 is arranged at the upper ends of two sides of the underframe 1, the rotating shaft 3 is arranged on the plate-type rotating shaft seat 7, the inner sleeve 4 is arranged outside the rotating shaft 3, the outer sleeve 5 is rotatably arranged outside the inner sleeve 4, the two inverted U-shaped swing arms 2 are respectively arranged at two sides of the underframe 1, and the lower ends of the inverted U-shaped swing arms 2 are fixedly connected with the outer sleeve 5; a plurality of steel rope buckles 6 are arranged on the inner side of the upper end of the inverted U-shaped swing arm 2; swing arm fixed plate 8 sets up on the chassis 1 of the junction of inverted U-shaped swing arm 2 and overcoat 5, and 8 upper ends of swing arm fixed plate are the arc, are provided with a plurality of bolt holes 8.1 in 8 upper end arcs of swing arm fixed plate, are equipped with one on inverted U-shaped swing arm 2 can with the fixed orifices 2.1 that each bolt hole 8.1 corresponds.

The working principle of the utility model is that one end of a steel wire rope 9 is connected with a lifting hook on a lifeboat 10, the other end of the steel wire rope 9 is connected with a steel wire buckle 6, the simulation of the pulling force of the lifting hook on the lifeboat 10 in the width direction of the lifeboat 9 is realized, the aim of simulating the tension of a hook on the lifeboat 10 in the direction of the captain of the steel wire rope 9 is achieved by rotating the two inverted U-shaped swing arms 2, thereby realizing the detection of the ultimate tensile force of the lifting hook in all directions of the steel wire rope 9 when the lifeboat 10 is in multi-posture simulated release, detecting the maximum tensile force of the lifting hook under the release state of various lifeboats, the lifting hook can be separated from the steel wire rope 9 in advance, or the lifting hook is damaged when being subjected to large ultimate tensile force in various lifeboat releasing states, and the lifting hook cannot be normally separated from the steel wire rope when being subjected to large ultimate tensile force in various lifeboat releasing states, so that the simulation of testing requirements of various postures of the lifeboat 10 during releasing is realized.
