Description

Technical Field

[0001] The utility model relates to the technical field of traffic road devices, specifically to a turnout conversion device for remote control of locomotives. Background Technique

[0002] In the railway traffic system, the turnout, as a key device connecting different track lines, the accuracy and timeliness of its conversion directly affect the operation safety and efficiency of trains. The conversion of traditional turnouts mainly relies on manual on-site operation or simple mechanical control, and this method has many deficiencies. First of all, manually operating the turnout on-site not only has a high labor intensity, but is also easily affected by environmental factors such as weather and night lighting, increasing the risk and difficulty of operation. Especially in emergency situations, manual operation may not be able to respond quickly, resulting in train operation delays or increased accident risks.

[0003] Secondly, although the mechanical control turnout conversion system realizes automation to a certain extent, its control accuracy and reliability are often limited by the wear and failure of mechanical components. With the rapid development of railway traffic, the requirements for the automation and intelligence of turnout conversion are increasing day by day.

[0004] At present, the turnout conversion devices put into use all have the advantages of realizing the remote automatic conversion of turnouts by integrating advanced communication technology, control technology and sensing technology, improving the conversion efficiency, reducing manual intervention, and enhancing the system safety.

[0005] However, when most turnout conversion devices are in use, generally only a slide rail and a slider are used for guiding operation. Although the slider and the slide rail can play a supporting effect, since the slider and the slide rail are slidably connected, the firmness of the support is relatively low. Most turnout conversion devices lack components that can promote movement, reduce friction and provide stable support at the same time, which will affect the stable operation of the entire system. In view of this, we propose a turnout conversion device for remote control of locomotives. Content of the Utility Model
