Highway-railway combined bond weld construction vehicle and application method

Abstract

The invention relates to the technical field of vehicular equipment, and in particular relates to a highway-railway combined bond weld construction vehicle and an application method. The construction vehicle is characterized in that a main vehicle system (1) is arranged in a cab, a flat car is provided with a welder container (2), the welder container (2) is internally provided with a hydraulic system (9), the bottoms at the two sides of the flat car are respectively provided with a railway front wheel support assembly (5) and a railway rear wheel support assembly (4), the bottom of the railway front wheel support assembly (5) is connected with a railway front wheel running assembly (7), and the bottom of the railway rear wheel support assembly (4) is connected with a railway rear wheel running assembly (8). Compared with the prior art, the construction vehicle not only can run on a highway and facilitate construction transition and site ingress and egress, but also can run on a railway and facilitate movement of a construction working plane, thereby being beneficial to forming specialized construction and specialized construction supporting capabilities.

Description

[technical field] [0001] The invention relates to the field of vehicle equipment, machinery and electromechanical technology, in particular to a road-rail rail joint welding construction vehicle and an application method. [Background technique] [0002] As a link in the construction of railway tracks and urban rail transit tracks, there is no unified requirement for the welding construction of on-site rail joint joints in China. Some lines adopt small gas pressure welding process, some use thermite welding process, and some use flash contact welding process. Flash contact welding process is more and more widely used because of its high quality welded joints. [0003] The flash welding equipment for on-site joint joints mostly adopts imported or domestically assembled equipment. The equipment uses containers to fix various parts of the equipment, and has its own generator set to meet the power demand of rail welding equipment. The rail welding equipment consists of six parts...

AI Technical Summary

Problems solved by technology

[0006] 2. The resource occupation time is relatively long

When welding rails, special railcars and construction flatbed trucks are required to be used together throughout the whole process. The relevant equipment equipped cannot be withdrawn until the welding work is completed, which will affect the use of this equipment in other constructions.

[0007] 3. The cost of transit transportation is relatively high

The transportation of rail cars, flat cars and rail welding equipment requires multiple large trailers for installation, and the transportation cost can easily be tens of thousands or tens of thousands, which is very expensive

[0008] 4. The length of the temporary track is relatively large during operation

During the rail welding operation, the rail car and the flat car form a train, and the length of the train is nearly 30m, which is not conducive to the follow-up of other processes of rail welding

[0009] 5. Due to the long length of the train, the newly welded joints are likely to be pressed by the rail car, and the phenomenon of low joints may occur, which affects the straightness quality requirements of the joints

[0010] 6. It is not conducive to the formation of professional construction

When rails are welded, railcars and flatbed transporters are generally used during track construction. The operator of the rail welding machine and the driver of the railcar need to cooperate very tacitly. If the railcars and drivers are replaced frequently, it is not conducive to the development of rail welding work. , not only affecting the construction progress but also likely to cause safety accidents

[0011] 7. Failing to form professional supporting construction capabilities

However, the equipped traction and transport vehicles have to be provided by each construction unit, and the coordination workload in the work is heavy, which may affect the construction progress and construction quality.
