Technical Field

The invention relates to the technical field of rail engineering, in particular to a highway and railway dual-purpose bidirectional running traction and cargo carrying transport vehicle and a using method thereof.

Background

At present, in the urban rail transit engineering rail construction in China, the rail material is transported from a rail laying base to a working face by adopting a mode of dragging a rail transport flat car by a rail-mounted traction locomotive. Because the rail-mounted traction locomotive has larger overall structure size (the length is 10000mm, the width is 2600mm and the height is 3800 mm), the rail material is transported to a working face in a pushing mode (namely the traction locomotive runs forwards at the back when the flat car is in front, the material transportation has directionality), drivers of driving tractors watch out certain influence, and the material loading and unloading and the transportation are limited to a certain extent. Particularly, when large objects such as a transport track panel (25000 mm long and 2100mm wide) are pushed, the length of the whole vehicle reaches 30-40 m, a driver cannot well observe the traffic condition of a front road, and certain potential safety hazards exist. In addition, because the weight of the rail traction locomotive is limited by the urban rail traffic interval structure and other shaft weight requirements, generally about 25000kg, the driving force is formed by the friction force between the steel wheel and the steel rail, when the rail traction locomotive runs on a wet rail section of a large slope, the friction force between the steel wheel and the steel rail is reduced, the phenomenon of idle running (slipping) of the driving wheel of the rail traction locomotive occurs, the rail traction locomotive cannot normally drive to run or slips, and great potential safety hazards exist. Moreover, because the height of the track tractor is high, when the track-laying machine (with the length of 4000mm, the width of 4000mm and the net height of 3500 mm) works on a working surface, the track-laying machine cannot stride over the track tractor to perform other operations (such as hoisting and transferring templates, concrete pump pipes and the like), certain restrictions are caused to the use of the track-laying machine, and the maximum function cannot be well exerted. In addition, because the track tractor adopts a rail-running steel wheel structure, the track tractor can only run on a track with a fixed track gauge, and the situation that track materials (track plates, sleepers and fasteners) are transported on a flat structural bottom plate cannot be realized. Moreover, the short-distance transportation on the same construction site can be completed only by means of the transportation of an automobile flat car.

In summary, although the conventional rail-mounted track transportation tractor is widely used in practical applications, the work efficiency of track construction is limited to a certain extent, the construction cost is increased, and a certain safety risk and exertion of the construction work efficiency exist during running. The condition of superelevation also happens when long-distance highway transit. At present, the construction technology of modern rail transit rail engineering is rapidly developed, and structures such as a plate type ballast bed, a prefabricated assembly structure and the like become a mainstream rail structure form. In order to meet the higher requirements of track laying construction efficiency, the self-adaptability, the multifunctional type and the flexibility of transport vehicle equipment have higher requirements, and the trend that larger operation space, effective operation time and the like become necessary is provided for positive line track laying, so that a novel highway-railway dual-purpose bidirectional running traction and cargo carrying transport vehicle is developed, which can realize the transportation of materials such as track materials, prefabricated products, assembled structures and the like in tunnels, and can also run and transport materials such as track plates, fasteners and the like on highways. Meanwhile, the energy-saving and environment-friendly road and railway dual-purpose bidirectional driving traction and cargo carrying transport vehicle which can realize the complete machine disassembly-free rapid transition and the long-distance transportation transfer is required to be a necessary trend and urgent affairs.

The lifting device comprises a guide wheel fixed support rod connected to the bottom of the frame, a lifting device hydraulic oil cylinder connected to the bottom of the frame and a guide wheel lifting device swing arm assembly, the guide wheel pair comprises guide wheels arranged at two ends of a cross shaft and two ends of the cross shaft, the cross shaft is rotatably connected to one end of the guide wheel lifting device swing arm assembly, the other end of the guide wheel lifting device swing arm assembly is connected with the lifting device hydraulic oil cylinder, the middle of the guide wheel lifting device swing arm assembly is connected with the guide wheel fixed support rod, and the swing arm can swing to realize the lifting of the guide wheel pair under the action of the lifting device hydraulic oil cylinder. Preferably, the lifting type rail wheel guiding and walking system further comprises an air bag compensator, the air bag compensator comprises an air bag and an air pump, the air pump is connected with the air bag to realize air inflation and deflation of the air bag, the air bag is arranged between the lifting device hydraulic oil cylinder and the other end of the lifting device swing arm assembly,

when the transport vehicle runs on the road, the guide wheel pair is lifted, and the transport vehicle can run on the road. When the guide wheel pair is lowered, the centers of the radial directions of the treads of the driving thrust wheel and the steering thrust wheel are overlapped with the center of the tread of the steel rail, the driving thrust wheel and the steering thrust wheel are supported on the tread of the steel rail, and the guide wheel pair is supported on the tread of the steel rail. And locking a steering lock of the steering axle, and enabling the vehicle to run along the rail direction of the steel rail under the guidance of the guide wheels to finish material transportation.

In addition, the vehicle adopts a battery pack power supply as a power source, and the battery adopts a lithium battery with large capacity. The inverter is used for converting the electric energy of the battery into input and output in a frequency conversion mode and the like, so that the power distribution of the vehicle is realized. The transportation vehicle further includes a brake and a parking brake of a general vehicle, for example, fig. 13 shows a schematic circuit diagram of a brake and a parking brake, in which an air tank is charged and discharged by an air pump, etc., so as to change the pressure applied by the air tank to the parking brake cylinder and the brake cylinder, and the air tank can push against a brake pad, so that the brake pad rubs against a brake drum, thereby reducing the vehicle speed or keeping the vehicle stationary. The operation system comprises a steering wheel, a variable box operating rod, a reversing box operating button, a motor, an inverter operating button, a brake and parking controller and the like, hooks used for being connected with the flat car are further arranged at the front end and the rear end of the transport car, and lifting points used for achieving lifting are further arranged on the transport car.
