High-speed railway track accurate adjusting device

Abstract

The invention relates to a high-speed railway track accurate adjusting device comprising a base and a prism, characterized by also comprising a vertical post and an elastic pressing device, the geometric center of the base and the reflection center of the prism are all arranged on the axis of the vertical post, the elastic pressing device is positioned on the base. The reflection center of the prism is in accordance with a tread center of a simulative rail, and the distance of the reflection center of the prism and the bottom of the base is equal to a height of the simulative rail. 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 tread 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 rail simulative 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 plate determined by the two outer slopes of the large jaw of the track plate 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 worklo...

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.
