Train door isolation switch spring bolt gap measuring tool

Abstract

The invention discloses a train door isolation switch spring bolt gap measuring tool. The measuring tool comprises a measuring ruler and a limiting bottom plate capable of making close contact with abottom of a travel switch. One end of the measuring ruler is connected with the limiting bottom plate; the limiting bottom plate is provided with a contact surface which can be in close contact with the bottom of the travel switch; and the measuring ruler is provided with a first scale and a second scale which are arranged on the same plane, the first scale is separated from the contact surface bya specified first vertical distance, the second scale is separated from the contact surface by a specified second vertical distance, and the first vertical distance is greater than the second vertical distance. In the invention, the gap between the isolation switch spring bolt and the travel switch can be conveniently measured, measurement precision is ensured, and measurement efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of measuring tools, and in particular relates to a tool for measuring the gap between a lock tongue of a train door isolating switch. Background technique [0002] In the prior art, the door of the B6 train adopts the plug door produced by Outme Company. Now when the door is being repaired, it is necessary to measure the gap between the isolating switch bolt and the travel switch. If the gap is too large, it will cause the operation of the isolating switch. The rear lock tongue cannot be in effective contact with the travel switch, which will affect the cutting effect. If the gap is too small, the travel switch will be triggered by mistake. [0003] At present, due to the narrow space between the lock tongue of the isolating switch and the travel switch, it is impossible to place a measuring ruler for measurement. The gap size can only be estimated by visual inspection. Among them, if the parameters are foun...

[0002] In the prior art, the door of the B6 train adopts the plug door produced by Outme Company. Now when the door is being repaired, it is necessary to measure the gap between the isolating switch bolt and the travel switch. If the gap is too large, it will cause the operation of the isolating switch. The rear lock tongue cannot be in effective contact with the travel switch, which will affect the cutting effect. If the gap is too small, the travel switch will be triggered by mistake

[0003] At present, due to the narrow space between the lock tongue of the isolating switch and the travel switch, it is impossible to place a measuring ruler for measurement. The gap size can only be estimated by visual inspection. Among them, if the parameters are found not within the required range during the visual inspection, It needs to be adjusted, and the parameters need to be confirmed again after the adjustment. If it is still unqualified, it will continue to adjust. Therefore, the process of "adjustment-test-adjustment" will appear repeatedly, seriously affecting the efficiency and accuracy of measurement.
