Speed-retarding checker

Abstract

The top box unlocked machine of the retarder top measuring speed desk is installed on the power machine using fasteners, and the slider blocks of the slider pulley group is installed on both slideway sides of the top box unlocked machine, and the small pulley is installed on the small pulley chair of the top box unlocked machine, and the sensor is installed in the sensing switch small chair's hole of the top box unlocked machine close to the switch fixed plate and the power machine. By pressing the up button, it pulls the slider block to the required height, and the tested retarder top is loaded into the retarder top oriented hole of the big pulley, and the retarder top piston rod fell to the increase plate, and the distance between the top end of the retarder top and the bottom end of the slider block is the testing speed power height value. By pressing down button, the slider block falls freely to the retarder top, and with the gravity acceleration formula V=2Hg, the speed on the whereabouts of the slider block to the retarder top is calculated. Adjusting several times the distance between the top end of the retarder top and the slider block, the critical velocity of the retarder top can be measured. The invention has small occupying size, low cost, high accuracy, and reliable security.

Description

technical field [0001] The speed measuring platform of a deceleration jack is a test device for detecting the critical speed of a deceleration jack, and belongs to the technical field of railway shunting safety equipment. Background technique [0002] At present, the deceleration jacks used in domestic railway marshalling yards can automatically judge the vehicle speed, and can brake and decelerate the vehicles exceeding the critical speed to ensure the safety of the vehicles. The critical speed is an important technical index of the deceleration jack. The detection of this indicator, only a few manufacturers carry out the factory products on the special test line, which needs to lay hundreds of meters of railway lines, use power locomotives and special vehicles, occupy a lot of land, high cost, low efficiency, and the application of deceleration When overhauling the deceleration jacks at hundreds of stations, the critical speed of the deceleration jacks after re-disassembly...

Problems solved by technology

The detection of this indicator, only a few manufacturers carry out the factory products on the special test line, which needs to lay hundreds of meters of railway lines, use power locomotives and special vehicles, occupy a lot of land, high cost, low efficiency, and the application of deceleration When overhauling the deceleration jacks at hundreds of stations, the critical speed of the deceleration jacks after re-disassembly and replacement cannot be detected, which affects the use effect of the deceleration jacks, and also has hidden dangers that endanger driving safety. It is urgent to solve a simple structure, easy to operate Handy speed detection device
