Problems solved by technology

Due to the complete functions of the latter, its structure is relatively large and heavy, and it cannot play its advantageous role in the narrow environment of the subway tunnel, and its usability is limited.
[0003] In summary, although the existing track-laying machines for track construction are widely used in practical applications, especially the type of track-laying machines that do not need to lay temporary running rails, although the construct

Embodiment 1

[0083] First of all, the road-rail track-laying machine should be in place on the working surface. Such as Figure 14 As shown, the gantry crane of the track laying base is used to lift the road-rail track-laying machine and move it to the rail material discharge port, and put it on the transport flatbed on the main track smoothly, such as transferring the road-rail track-laying machine The supporting legs are placed on the flatbed car and fixed with a fixed jack rope to complete the loading operation of the road-rail dual-purpose track laying machine. Then the rail tractor pushes the loaded rail-rail laying machine to the place where the operation is required, and then stops to prepare for unloading.

[0084] When unloading, first of all, remove the jack rope that fixes the road-rail track-laying machine, and check whether the surrounding environment meets the unloading and parking conditions of the road-rail track-laying machine. After everything is correct, start the powe...

Embodiment 2

[0095] The working surface transfer and long-distance transfer operation of the road-rail track-laying machine are as follows. When the road-rail track-laying machine completes the track-laying operation of the working surface and needs to transfer to the new working surface for operation, follow the steps below.

[0096] 1. Homework preparation

[0097] Stop the road-rail dual-purpose track-laying machine at the position where the poured integral track bed is convenient for loading, release the double-machine linkage and resume single-machine operation.

[0098] 1. Turn the first road-rail track-laying machine into the working state of hoisting new rail rows and stop the operation. Command the track tractor to push the unloaded transport flatbed car to park at a suitable position near the road-rail dual-purpose track laying machine (one flatbed car is equipped with two road-rail dual-purpose track laying machines) to stop and brake.

[0099] 2. Micro-move the height elevatio...

Abstract

The invention relates to the technical field of rail construction, and in particular relates to an urban rail transit engineering highway-railway dual-purpose rail layer and a using method thereof. The device comprises a frame structure, a walking mechanism and a hoisting system; the frame structure comprises a frame; the frame comprises a side frame structure and an upper connecting frame structure; the side frame structure comprises a lower fixed structure and an upper movable structure; the upper movable structure can stretch out and draw back relative to the lower fixed structure; the upper connecting frame structure comprises a fixed structure and a movable structure, and the movable structure can stretch out and draw back relative to the fixed structure; the walking mechanism is connected with the frame structure and used for moving the frame structure; and the hoisting system is arranged on the frame structure and used for hoisting. Compared with the prior art, the combined structure is simple and feasible; the structure for changing the running track distance of the highway-railway dual-purpose rail layer for urban rail transit engineering and the structure for changing thespan of the whole machine are separately designed; the walking mechanism is designed to be of a height and position adjustable structure; and corresponding change requirements can be met according toworking condition requirements.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a road-rail track-laying machine for urban rail transit engineering and a method for using the same. Background technique [0002] At present, in the track construction of urban rail transit projects, the construction of the concrete monolithic track bed adopts the construction technology of the frame rail method. The overall hoisting, transportation, and positioning of the rail row working surface are the key links to realize the rail-mounting process. The track laying machine is used to complete the hoisting of the working surface of the rail row. The rail laying machine lifts the prefabricated and assembled rail row from the rail row assembly base by the engineering vehicle from the transport vehicle and transports it to the design and installation position of the rail row for a short distance. In addition, the temporary auxiliary materials (temporary running rail...
