Carbon sliding plate anti-impact force testing device and method

Abstract

The invention discloses a carbon sliding plate anti-impact force testing device and method and belongs to the technical field of railway transportation. The testing device comprises a base, wherein the base is provided with a mounting seat; two compression brackets which are distributed from front to back are arranged at two ends of the mounting seat respectively; a compression plate is arranged on the two compression brackets at the same side; the compression plate moves up and down along the compression brackets; a sliding groove is formed between two groups of the compression brackets at two ends of the mounting seat; the sliding groove is located beside a carbon sliding plate; a sliding block is arranged in the sliding groove; an impact supporting rod is arranged on the sliding block;a rotary shaft is arranged at the top of the impact supporting rod; the rotary shaft is connected with a droopy impact connecting rod; the end part of the impact connecting rod is connected with an impact part; the impact part comprises an impact mounting device and a collision part; the collision part is arranged toward the carbon sliding plate. According to the carbon sliding plate anti-impact force testing device, an existing testing device is improved, so that a plurality of times of experiments are carried out more conveniently by adopting the structure under the condition that the carbonsliding plate is not detached.

Description

Technical field [0001] The invention relates to the technical field of carbon skateboards, in particular to a device and method for testing impact resistance of carbon skateboards. Background technique [0002] As an important component of the train, the quality of the carbon skateboard directly determines the safety of train transportation. Since the carbon skateboard is always in contact with the wire, in the process, if there are foreign objects under the wire, it may cause an impact on the carbon skateboard. Therefore, Understanding the impact resistance of carbon skateboards is an important step for the quality control of carbon skateboards. In the railway industry standard TB1842.3-2008, there are experimental requirements for the allowable impact energy of skateboards. Currently, the equipment used to test the impact resistance of carbon skateboards , Its structure is simple, although it can also complete the test requirements, but most of them can only test the impact res...

[0002] As an important component of the train, the quality of the carbon skateboard directly determines the safety of train transportation. Since the carbon skateboard is always in contact with the wire, during the process, if there is a foreign object under the wire, it may cause an impact on the carbon skateboard. Therefore, Understanding the impact resistance of carbon skateboards is an important step for the quality control of carbon skateboards. In the railway industry standard TB1842.3-2008, there are experimental requirements for the impact energy allowed by skateboards. Currently, the equipment used to test the impact resistance of carbon skateboards , its structure is simple, although it can also meet the test requirements, most of them can only test the impact resistance of one point, and cannot be impacted by obstacles of different structures, nor can it be subjected to multiple impacts on the same carbon skateboard at different positions. To carry out these experiments, it is necessary to constantly disassemble and fix the carbon slide, which brings great inconvenience to the experiment
