High-speed railway track accurate adjusting device

Abstract

The invention relates to a high-speed railway track accurate adjusting device comprising a base (1) and a measuring device. The high-speed railway track accurate adjusting device is characterized by also comprising a vertical post (2) and an elastic pressing device, the measuring device is a prism (3), the geometric center of the base (1) and the reflecting center of the prism (3) are both positioned on the axis of the vertical post (2), and the elastic pressing device is positioned on the base (1). When a track is accurately adjusted, the three-dimensional coordinate of the prism (3) is measured in real time by a measuring robot controlled by software and a track plate is adjusted through an accurate adjuster so that the geometric position of the track using the rail top of a steel rail as a reference is accurately adjusted to the designed position. The invention has the advantages of convenient installation, simple manufacturing, low manufacturing cost and no need of polishing the track plate; and when the track is accurately adjusted, a steel rail simulating device is measured in real time by the measuring robot controlled by software so that the geometric position of the track is accurately adjusted to the designed position.

Description

technical field [0001] The invention belongs to a device for accurately adjusting the track in a high-speed railway ballastless track system, in particular to a CRTSII type slab ballastless track system, which utilizes tooling to simulate the track to be laid, and adjusts the track slab to make the spatial position of the track to be laid Meet the design requirements. Background technique [0002] For the CRTSII type slab ballastless track, the well-known track slab fine-tuning method is to use the Borg fine-tuning system to fine-tune the track slab based on the two outer slopes of the large jaw of the track slab. Its essence is to precisely adjust the geometric axis of the track slab determined by the two outer slopes of the large anchor port of the track slab to the line design position. This method has the following disadvantages: [0003] 1. The grinding error data of the large jaw is required for fine adjustment, so the track plate must be ground, which increases the ...

AI Technical Summary

Problems solved by technology

[0003] 1. The grinding error data of the large jaw is required for fine adjustment, so the track plate must be ground, which increases the workload

[0004] 2. Only the grinding error of the large jaw is considered during fine adjustment

[0005] 3. The Borg fine-tuning system is too complex, requiring a large number of mathematical conversions, complex operations, and error-prone software design and actual use

[0006] 4. Because the track needs to be simulated through the large jaws, the Boger fine-tuning system uses many and large tooling equipment, which requires multiple large boxes to fit in. Not only is it difficult to manufacture and transport, but also the cost is high. Must be calibrated on site

[0007] Although there are various brands of localized fine-tuning systems in China, the concept of fine-tuning has not changed. They all adopt Borg’s fine-tuning ideas. Therefore, the shortcomings of the system still exist.
