Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The structure of an embodiment of the present invention is as Figure 1 to Figure 2 As shown, the railway brake hose impact performance test tooling of this embodiment includes a power mechanism, an electromagnet 7 that moves up and down driven by the power mechanism, and a test base 4. When energized, the weight 1 is adsorbed on the bottom of the electromagnet 7, the base 4 is set under the weight 1, and the base 4 is provided with a groove for placing the railway brake hose, and the railway brake hose 5 is placed horizontally in the groove Inside, the upper surface of the railway brake hose 5 protrudes outside the groove. The groove is a V-shaped groove, and the maximum width of the V-shaped groove is smaller than the diameter of the railway brake hose 5 . The power mechanism of this embodiment includes a fixed pulley 10 arranged a...

Abstract

The invention discloses a test device for impact performance of a railway brake hose, and the test device comprises a power mechanism, an electromagnet, and a test base. The electromagnet is lifted and lowered by the power mechanism. A counter weight is arranged below the electromagnet, the weight counter is adsorbed at the bottom of the electromagnet when the electromagnet is energized, the testbase is disposed under the weight counter, and the base is provided with a groove for placing the railway brake hose. The railway brake hose is horizontally placed in the groove, and the upper sursurface of the railway brake hose is protruded outside the groove. In impact performance tests, firstly, an insertion piece is inserted into the railway brake hose, then the railway brake hose is horizontally placed in the groove on the base, the power mechanism is used to raise the electromagnet and the weight counter to a set height position, the electromagnet is de-energized, the weight counter falls, and the weight counter hammers the expanded convex portion of the hose. The impact performance of the hose can be evaluated by hammering the hose with the weight counter and observing whether thehose is deformed or damaged. The device is simple and convenient to operate, and the weight counter falls due to de-energizing of the electromagnet, so that the safety is improved.

Description

technical field [0001] The invention relates to a test tool for the impact performance of a railway brake hose, belonging to the technical field of impact test devices. Background technique [0002] With the rapid development of my country's railway industry, the safe operation has attracted more and more attention from the government and society. Railway brake hose is an important part of the truck braking system and plays a vital role in the safety of truck operation. The impact test is an important performance index for investigating railway brake hoses, but there is no special device for impact tests on railway brake hoses in the existing technology. The existing technology uses manual impact tests, and the efficiency is relatively low. The test results have large errors. Contents of the invention [0003] The purpose of the present invention is to provide a railway brake hose impact performance test tool to solve the technical problems of low efficiency and large er...
