Description

TECHNICAL AREA

The present utility model relates to the technical field of railway technology, in particular to a multi-axle powered flatbed wagon with dual use for country roads and railways and a wagon group.

STATE OF THE ART

The track-laying project is an important transitional link in the light rail construction project and an important construction node, and is the second phase of the city's three-stage light rail construction project - line passage, rail passage and electrical connection. The completion of the track-laying construction marks an important step for a light rail line towards the trial operation of the line, which is moving from shell construction to equipment installation. Track construction consists of a series of interrelated construction processes. Among these many processes, the material transport on the railway is one of the key operations, is the process of transporting the main materials of the track bed, such as the rail row and the track plate, to the position of the construction work surface, and is also a crucial step whether the track construction can be completed successively can.

In the material handling of urban railways, wagons and flatbed trucks are often used in cooperation with traction work to transport the main materials of the track bed such as railroad tracks and track plates. The traditional railway material transportation method usually uses a gantry crane to lift the rail row from the unloading port to the flatbed truck on the underground main line, and in cooperation with the traction of the rail car, push the flatbed truck backward to the construction site surface, and the rail row with the rail laying machine to the construction site lift. In the process, when the flatbed truck transports the long row of rails and pushes the rail material in the reverse direction, the perspective of the truck driver will be somewhat affected, and the whole becomes narrow and long, which is inconvenient for the rail laying machine to straddle the lifting process, and the loading, unloading and the transport of the material is subject to certain restrictions. The equipments of the whole machine are heavy, and the axle load is limited by the structure of urban rail traffic; When driving with steel wheels, the weight of the flatbed truck and the rail car is different, and it is easy to tilt, and idling and slipping are easy to occur on wet roads of large ramps.

At the same time, railway wagons and platform wagons, which are special equipment, may only run on the tracks that have already been built. Currently, with the advent of prefabricated slab construction, there is a new demand for railroad material handling equipment that can run on the tunnel bed, and conventional equipment is unable to meet this demand.

And the entire steering rack 1-3 is connected to the main body of a car body 1-1 through a connecting plate 3-2 and a vibration damping device 1-8.

The power frame 1-4 is also connected to the main body of a car body 1-1 through a second connecting plate 3-2 having the same structure as the first connecting plate 2-3 of the steering frame 1-3 and a vibration damping device 1-8. The main body of the power frame 1-4 consists of a second connecting plate 3-2 and a gear component 3-1, is connected to the driving motor 1-6 on the car body through a gear universal joint 1-7, and provides the three-axle power flatbed truck dual-use for highway the forward motion force. Since the drive frame 1-4 and the steering frame 1-3 are of the same type, they can be easily exchanged.

In addition, a power supply system 1-5 of the car body is also arranged between the power frame 1-4 at the lower part of the main body of a car body 1-1 and the steering rack 1-3.

Exemplary embodiment 2: A three-axle railcar with dual use for country roads and railways transports materials on rails

First select the number of dual-use motor flatbed trucks for highway and railway according to the length of the material to be transported. Next, use lifting equipments like gantry cranes to lift the dual-use highway and railroad truck to the rails in the tunnel one by one. And then connect the respective power cars by the connecting hooks 1-2.

During the hauling process, each powered flatbed truck provides power. In addition, due to running on the rails, the front and rear steering racks 1-3 do not have to work, and the whole car only needs the drive frame 1-4 to provide power, and the running direction of the car body can be guided by the rail. Since the height of the railcar is smaller than the clear height inside the track construction machine or other hoists after reaching the destination, the staff can directly use the track construction machine or other hoists in the tunnel for material transport.

Exemplary embodiment 3: A three-axle railcar with dual use for country roads and railways transports materials on the tunnel bed

First select the number of dual-use motor flatbed trucks for highway and railway according to the length of the material to be transported. Next, use lifting equipments like gantry cranes to lift the dual-use highway and railroad truck to the rails in the tunnel one by one. And then connect the respective power cars by the connecting hooks 1-2.

During the hauling process, each powered flatbed truck provides power. In addition, due to driving on the tunnel roadbed, the steering racks 1-3 must provide steering guidance for the car body, at the same time, the deflection directions of the front and rear steering racks 1-3 are the same to reduce the torque when the entire car rotates, and thus the To improve the stability of the entire car.
