Problems solved by technology

Due to the long operation time of the subway, the fatigue period of the rails has reached the service life, and the wear of the working edges of the rails leads to poor track ride comfort, serious track settlement, rust, etc. when entering and exiting the station. The braking sound is harsh, which affects the comfort and safety of passengers. in need of urgent replacement
[0003] At present, 25m rails are generally used for rail replacement in domestic subway operation lines. The 25m rails are transported to the section where the underground line needs to be replaced, and then the 25m rails are welded into long rails for replacement. The construction period of 25m rail replacement is long, rail transportation, welding, replacement, etc. The processes are all completed in the skylight operation point after the subway is out of service. There are high potential safety hazards and a large investment in protection supervision. If a process lags behind, it will affect the train operation time of the next day

Embodiment 1

[0037] In this embodiment, using the existing subway vehicle base lines and the current situation, a long rail storage platform that meets the requirements of welding 25m rails into 100m is planned and constructed, including the welding operation area and the rail storage area. First, the 25m rails are welded in the welding operation area The 100m-long steel rail is formed, and then slides longitudinally through the roller shaft structure to the long rail storage area for transportation, and uses the subway outage time window to transport the 100m long steel rail to the underground line replacement site, and welds it into the replacement length for replacement in the selected time window.

[0038] Specifically, see Figure 5 As shown, the 25m rail is hoisted to the rail welding work area by a gantry crane with a span of 10m at the base, and two 25m long rails are welded with a rail welding machine, and then the rails are slid longitudinally through the roller shaft structure an...

Abstract

The invention relates to the technical field of rail engineering, in particular to a subway operation line base long steel rail welding platform device and a using method thereof. The subway operation line base long steel rail welding platform device comprises a welding working area, wherein the welding working area is provided with a transferring structure used for transferring steel rails; roll shaft structures, wherein the roll shaft structures extend from the welding working area to the parallel direction of an existing line, each roll shaft structure comprises a supporting frame and a roll shaft assembly arranged on the supporting frame, and the supporting frames are used for supporting the roll shaft assemblies to the same height of the existing line. Compared with the prior art, the combined structure is simple and feasible, is easy to mount and dismount, and has the advantages that the normal operation of a subway line can be maintained, the travel of passengers is not influenced, the subway operation safety is ensured, the long steel rail welding platform is constructed by utilizing an original subway operation line vehicle base, and a 25m steel rail is welded into a 100m long steel rail; and therefore, the replacement speed is greatly improved.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a long rail welding platform device for a subway operation line base and a method for using it. Background technique [0002] With the expansion of the scale of domestic subway construction, problems such as outdated equipment, track wear, aging of rail materials, and cracking of track beds have gradually appeared on the lines that have been built for operation. Line maintenance will become a new industry. Due to the long operation time of the subway, the fatigue period of the rails has reached the service life. The wear of the working edges of the rails leads to poor track ride comfort. Serious track settlement, rust, etc. when entering and leaving the station, the braking sound is harsh, which affects the comfort and safety of passengers. It needs to be replaced urgently. [0003] At present, 25m rails are generally used for rail replacement in domestic subway operat...
