An inflatable life raft pressure release device test device

Abstract

The invention relates to a device for testing life rafts and discloses a device for testing an inflatable life raft pressure release unit. A horizontal lifting frame (1) has a U shape, a balance bar is fixedly connected to the upper parts of two side frames respectively, and floaters (7) are fixed at two ends of balance bars; a bearing is respectively arranged at central positions of the two sideframes and is rotationally connected with a life raft mounting turntable (6); one side of the life raft mounting turntable (6) is connected with one end of a life raft pressure release unit (5) to betested; the other end of the life raft pressure release unit (5) to be tested is penetrated by a rope (8); the two ends of the rope press against an expansion life raft (3) and are wound on a rope winding stick (10); the rope (8) can be tightened by a rotating hand wheel (4); and one or two graduated disks (2) are fixed on the side frames of the horizontal lifting frame (1). The invention provides a device for testing and judging whether a life raft pressure release unit releases pressure qualifiedly or not at a standard specified water depth when the life raft pressure release unit to be tested and the bound expansion life raft are put into water together, the device is convenient to use and operate, the influence of personal factors is eliminated, and all standard specified parameter items can be finished on one device.

Description

technical field [0001] The invention relates to a test device for a life raft, in particular to a test device for the test of an inflatable life raft pressure release device in the life raft product inspection item. [0002] Background technique [0003] Life raft is a kind of life-saving facility that ships must be equipped with when operating on water, and it is the most direct and rapid self-rescue tool after a water accident occurs. At present, inflatable liferafts are used both at home and abroad. Just pull the start cable to inflate the liferaft carcass and play the role of rescue in water. With the rapid development of my country's economy, the domestic demand for life jackets continues to rise. In recent years, many companies have pushed their products to the international market. The inflatable life raft has the advantages of convenient use, rapid inflation and forming, more people to be rescued, and good thermal insulation performance. Once encountering a maritim...

Problems solved by technology

[0006] The current status quo is that there are test standards, but there are no specific test methods and test devices. Each production or user unit only builds and assembles some single-item institutions. The test procedures are cumbersome and the test speed is slow. Therefore, in today's vigorous development of inflatable life rafts, there is an urgent need for a testing agency with fast testing speed, convenient operation, and a testing agency that strictly complies with the CB3065-1994 standard.
