Description

Highway-railway dual-purpose track laying machine for urban rail transit engineering and use method thereof

Technical Field

The invention relates to the technical field of track construction, in particular to a highway and railway dual-purpose track laying machine for urban track traffic engineering and a using method thereof.

Background

In the current urban rail transit engineering rail construction, the concrete monolithic roadbed rail construction adopts a rail erecting construction process for construction. The integral hoisting, transportation and positioning of the track panel operation surface are key links for realizing the rail erecting method process operation. The track laying machine is adopted for completing the hoisting of the working surface of the track panel. The track laying machine lifts the engineering vehicle from the track panel assembly base to the track panel design and installation position for a short distance, and integrally erects the track panel by means of the track adjusting bracket to complete the field hoisting operation of the track panel. In addition, the temporary auxiliary materials (temporary running rails, ditch templates, side track templates, track state adjusting support frames, concrete conveying pipes, electric welding machines and the like) during the construction of the integral track bed are transferred from the current operation position to the next operation position through the hoisting function of the track laying machine. Thus, the track-laying machine makes a key equipment for track laying construction. The track-laying machine for the current track construction has various forms, which are summarized into three types: the track laying machine is a simple track laying machine which adopts a fixed structure form (the span is 3000mm-3200mm, the height is 3200mm-3500mm), and walks on temporary walking tracks which are paved on two sides of a track bed in advance. The other is a track laying machine with variable span and height, namely, the track laying machine adopts a telescopic structure in the height aspect, adopts a guide sleeve guide post structure in the span aspect, realizes the changes of the span (2900mm-3800mm) and the height (2500mm-3800mm) of the track laying machine through a hydraulic oil cylinder or an electric lead screw so as to meet the operation under the boundary conditions of different heights and widths, and runs on temporary tracks which are laid on two sides of a track bed in advance. The track laying machine has the advantages that temporary tracks on two sides of a track bed do not need to be laid in advance. The method is characterized in that the method comprises two walking modes, namely, one mode is that the walking wheels are designed into a structural form capable of changing in an inclined mode, the walking wheels adopt a structure that a steel matrix walking contact surface is wrapped by rubber materials, and the walking wheels walk on a structural bottom plate or a segment side wall of a shield tunnel according to different boundary conditions. And the other is to adopt two sets of running mechanisms, wherein one set of running mechanisms is steel track running wheels and runs on the main track, and when the section without the main track runs on the structural floor by adopting the crawler running mechanism, the two sets of running mechanisms are converted according to boundary conditions to realize running transportation. The former has very limited operation boundary of the inclined rubber wheel walking track laying machine, and is only suitable for the operation environment of laying a precast slab track bed on a shield tunnel structure or a flat bottom plate. The latter has a larger and heavier structure due to complete functions, cannot play its advantages in the narrow subway tunnel environment, and is limited in usability.

In summary, although the conventional track laying machine for track construction is widely adopted in practical application, particularly the type of track laying machine which does not need to lay a temporary running track is adopted, the construction process which does not need the temporary running track is solved, the construction links are reduced, and the construction investment is reduced, one is to solve only the boundary environment of operation in a shield tunnel, and the other is to find the condition that the structure of the track laying machine is larger, so that the advantages of the track laying machine cannot be fully exerted in the environment of the subway tunnel, and the work efficiency cannot be better improved. At present, the modern rail traffic rail engineering construction technology is rapidly developed, and in order to meet the higher requirements of rail laying construction efficiency, the rail laying machine has higher requirements on adaptivity, multifunction and flexibility, and provides larger operation space and effective operation time for rail laying construction, avoids the phenomenon that different tunnel structures need multiple rail laying machines to operate, reduces cost, improves work efficiency and the like, and becomes necessary trend, so that the development of a novel rail laying machine for both highway and railway can realize rail laying in different tunnel boundary conditions, hoisting and transportation of materials, prefabricated products, spliced structures and the like, can also walk and transport on a flat structural bottom plate and a bridge floor, is light, handy, flexible and convenient to operate, and simultaneously meets the requirements that a complete machine is not required to be disassembled, the complete machine is quickly transferred to the ground, and the energy-saving and environment-friendly rail laying machine for long-distance transportation transfer becomes necessary trend, It is urgent to take care of it.

Fourthly, the long-distance transportation flat car (the length of the car is 10 m-15 m) is parked at a proper position in the operation range of the large gantry crane of the track laying base. Commanding the gantry crane to hoist the rail paving machine for both highway and railway to be stably placed at a proper position on the transporting flat car (one transporting car loads two rail paving machines for both highway and railway), and padding a wood plate with the thickness of 50mm at the lower support foot of the loading support frame of the rail paving machine for both highway and railway. Similarly, another rail paving machine for both highway and railway is arranged on the flat car in the same way. After loading, the rail paving machine for both highway and railway and the flat plate are firmly bound by a fastening lifting rope, so that the rail paving machine for both highway and railway is prevented from loosening, shaking and shifting during transportation. Long-distance transportation can be carried out after all mistakes are made.

And commanding the semi-trailer flat car of the automobile to convey the rail paving machine for both the highway and the railway to a new construction site, and unloading the vehicle. And finishing long-distance transition transportation.

The reference numbers in the figures are as follows:
