Description

Technical Field

[0001] The invention relates to the technical field of track operation, and in particular to a trolley for maintenance operation of subway tunnel structure. Background Art

[0002] With the increase in subway operating mileage and operating time, the maintenance and upkeep of the civil structures of rail transit tunnels and underground stations face many problems, and water leakage control is a relatively important one. In order not to affect the normal operation of the train, water leakage control is usually carried out during the "window" time. The transportation and installation of tunnel maintenance equipment takes a long time. It is urgent to develop a set of subway section maintenance and construction vehicles to realize the rapid transportation of equipment and assist workers in construction through automated equipment.

[0003] Small-scale subway tunnel maintenance equipment is currently mainly in the form of scaffolding. There are two forms of moving on the trackside and moving on the track. The working platform has a scaffolding and a single-person lifting mechanism. The time at the skylight point is precious. The existing technology is to transport equipment and materials from the platform to the track area one by one at the beginning of the skylight, and the scaffolding is built in the working area, which is time-consuming.
