Gravity balance type digital display superelevation detection device

Abstract

The gravity balance type digital display superelevation detection device comprises a gearbox supporting frame, an adjustable auxiliary mechanism is fixedly arranged at the bottom of the gearbox supporting frame, a plurality of moving assemblies are fixedly arranged on the adjustable auxiliary mechanism, a gearbox is arranged on the back face of the gearbox supporting frame, a balance block is arranged on the back face of the gearbox, and the balance block is arranged on the back face of the gearbox. The gearbox supporting plate is provided with a protective cover, the gearbox and the balance block are both located in the protective cover, and the surface of the gearbox supporting plate is provided with a rotary grating liquid crystal display module. Compared with the first generation, the ultra-high display has the advantages that the gear modulus is changed from 0.5 to 0.25, a straight gear is changed into a bevel gear, and the protective cover is added; mechanical pointer display is changed into digital display, so that each position can be fully engaged to avoid fine swing gaps, the influence on the reading due to the large windward side of the balance block is avoided, the operation is smoother, and the precision is higher as the digital display reading is more convenient, and the reading resolution is improved by 20 times from 1mm to 0.05 mm.

Description

technical field [0001] The invention relates to the track field, in particular to a gravity balance type digital display superelevation detection device. Background technique [0002] Track inspection vehicle is a special vehicle used to detect the geometric state and irregularity of the track in order to evaluate the geometric state of the track, referred to as the track inspection vehicle. It is an important tool to ensure driving safety, stability, comfort and guide track maintenance. [0003] According to the records of the track inspection vehicle, it is possible to find the location where the track is not smooth, so that emergency repairs or speed limit measures can be taken, and the mileage section that should be planned for maintenance can be determined, and the maintenance operation plan can be compiled. [0004] In 1953, China successfully trial-produced the first self-designed passenger car mechanical track inspection vehicle. In 1971, China made the "TSK22" ele...

AI Technical Summary

Problems solved by technology

[0007] During the initial track adjustment process, there are many times of track super-elevation adjustments, and it is inconvenient to use large-scale equipment, because the current device cannot display the super-high value well The data still needs to be measured by the staff. Not only is the troublesome data not continuous, it is also random sampling data, which is not conducive to operation and comparison with theoretical values. Therefore, we have designed a gravity-balanced digital display ultra-high detection device
