Hoisting device of underground railway line turnout assembly and hoisting method

Abstract

The invention discloses a hoisting device of an underground railway line turnout assembly and a hoisting method. The device comprises a hoisting framework, a traction mechanism and a walking mechanism. The hoisting method comprises the steps that the hoisting device is transported to a vertical well mouth and hoisted by hoisting equipment, and the hoisting device is transported into a vertical well; and the hoisting device is dragged by a tractor to walk into a hole, the hoisting equipment is in close cooperation, the hoisting device is pulled by the tractor to walk in the hole, and the turnout assembly is hoisted to a storage position. The hoisting device and the hoisting method have the beneficial effects that during underground station construction, the turnout assembly is hoisted into the hole from the vertical well mouth, and compared with the manner of transporting in the turnout assembly from a tunnel portal, the transport distance is remarkably reduced, the construction efficiency is improved, and the logistics cost is reduced; and the turnout assembly does not deform in the transfer process, and the turnout pavement precision can be easily controlled.

Description

Technical field [0001] The invention belongs to the technical field of railway track construction, and relates to a lifting device and a lifting method for turnout components of an underground railway line. Background technique [0002] In recent years, more and more subway stations and intercity railway stations have been installed underground to meet the needs of urban development. Station turnouts, especially large-size turnouts in intercity express railway stations, have a large number of components, large scale, precise structure, and high deformation control requirements. Therefore, the transportation of turnout components is a technical problem to be solved urgently in the construction of turnouts in underground railway stations. [0003] In the construction of the turnouts in conventional underground stations, the components are transported through the tunnel opening and transported by rail cars. The transport distance is even tens of kilometers. Due to the long transport...

AI Technical Summary

Problems solved by technology

Due to the long transportation distance, it is also greatly affected by other constructions in the tunnel, so the transportation cost is high, the process arrangement is difficult, and the turnout is easily deformed during transportation, which affects the laying accuracy

At the same time, the construction of the turnout can only be arranged after the construction of the section line is completed, and can only be constructed by changing the paving method

[0004] During tunnel construction, vertical shafts are generally set up at or near the station as a construction transportation channel, but due to the small diameter of the vertical shaft, conventional devices cannot be used to lift and transport turnout components through the vertical shaft

There is a lack of a device for hoisting and transporting turnout components of underground railway lines through small-diameter shafts in the prior art
