Description

Technical Field

[0001] The present invention specifically relates to a continuous disassembly and assembly fixing device for replacing curved rails of trains. Background Art

[0002] Replacing old train tracks with new ones is a complex and delicate process involving multiple steps and specialized technical requirements. The following is a detailed breakdown of the track replacement process: It begins with preliminary preparation, removal of the old track, laying of the new track, and quality control. Preliminary preparation involves routine flaw detection by rail inspectors using flaw detectors to detect damage invisible to the naked eye. Once a damaged rail is discovered, engineers are promptly notified and a track replacement plan is laid. Based on the inspection results, a detailed track replacement plan is developed, including the construction time, location, required materials, and personnel division. Track removal involves dismantling and cutting the old track. After cutting, workers remove the old track from the center of the track and move it to the shoulder. New track laying involves removing the old track and then re-installing it. Once the new track is in place, the rail welding team performs welding. This process involves setting up formwork, setting up a furnace, adding materials, and igniting the furnace to join the two rails together.

[0003] During the removal of old track and installation of new track, rail expansion and contraction are limited. Due to the geometric characteristics of the track in curved sections, which means there is a shortening of the curve, the length of the upper and lower rail strands must be adjusted, specifically shortening the upper strand and lengthening the lower strand. The current method for handling this problem uses acetylene to cut the rails and install splints, loosening bolts to relieve stress. This results in the old rails being cut into short sections of 50-150 meters, which then need to be re-welded into long rails for reuse, increasing operational costs and posing safety risks.

[0004] Furthermore, this method presents significant risks with welded joints, primarily in the form of rail breakage, line defects, and high costs and low efficiency. Statistics show that over 85% of rail breaks occur at welded joints, directly impacting line safety. 80% of welded joints exhibit issues such as dents and empty hangers, impacting train operation smoothness. High costs and low efficiency: Each 0.4-kilometer-long rail replacement requires 14 welded joints, involving oxyacetylene cutting, rail alignment, and thermite welding. The combined material and labor costs for plywood, welding materials, and wire total approximately 76,780 yuan per rail. Furthermore, the need for railcars contributes to low efficiency. In short, during the removal of old rails and installation of new ones, there are no specialized tools to regulate the positioning of each joint between the old and new rails during the replacement process.
