Problems solved by technology

This method is currently a common practice in China. This kind of test bench has low adaptability. During the test, the lowering device needs to be positioned multiple times, and the type test and product test cannot be completed by fixing it on the test bench at one time. The work intensity is high. Poor safety assurance, long test preparation time and auxiliary time
[0006] 3. According to the state of heel and pitch, through the decomposition of the working load, the simulated force is applied to the tested launching device. The main disadvantage of this method is that the test state is not real, and it cannot really simulate the test state to meet the test requirements. status requirements

Abstract

The test-bed includes following parts and structures: up platform and low platform, their back ends connected through longitudinal inclination (LI) shaft; through front pendulum stanchion, and up free bearing respectively, LI oil cylinder is connected to up platform and low platform; transverse inclination (TL) up free bearing, and TL low free bearing are connected to low platform and base; TL spacer is connected to low platform, and TL base of locating pin is connected to foundation; through up free bearing of TL oil cylinder, and low free bearing of TL oil cylinder, up end and low end of TL oil cylinder are connected to low platform and foundation. Fixing installation for lowering lifeboat on test-bed for once can carry out each test in simulating states of mother ship including horizontality, each longitudinal, transverse inclination, single or combined instances. Futures are: simple operation, small investment and saving testing time.

Description

(1) Technical field [0001] The invention relates to a test equipment for various types of lifeboat launching devices, in particular to a test bench for lifeboat launching devices. (2) Background technology [0002] In accordance with the requirements of the "International Life-saving Appliances Code (LSA)" and the "MSC Resolution MSC.81(70) on the Test of Life-saving Appliances" formulated on the basis of it, the type test of the launching device of lifeboats (except free-fall lifeboats) should simulate the mother ship The dynamic load test is to be carried out in the state of both inward and outward heel of 20° and trim of 10°; for the launching device of the free-fall lifeboat, it is to simulate the state of the mother ship with both heel of 5° and trim of 2° Carry out a dynamic load test. The product test of the launching device is only carried out in the horizontal state. [0003] At present, there are three main methods for simulating inclination tests of lifeboat lau...
