Further, the vehicle body 11 has a rail unloading portion 116, the rail unloading portion 116 is located below the bearing member 14, the rail unloading portion 116 is parallel to the rail retracting portion 115, and the rail unloading portion 116 is used for rail unloading.
Specifically, the rail unloading portion 116 may be a fixed passage provided in the vehicle body 11, and the rail collecting portion 115 may be provided in one piece with the rail unloading portion 116, that is, have a rail unloading function and a rail collecting function, or may be provided separately, in order to prevent a collision between the rail collecting and rail unloading structures, the rail unloading portion 116 and the rail collecting portion 115 may be parallel to each other, and the rail unloading portion 116 may support and guide the rail when unloading the rail.
Optionally, the end wall 113 has an opening 1131 for receiving and removing the rail.
Specifically, since the length of the transported rails is substantially the length of the train set of the transported rails, and the rail receiving portion 115 and the rail discharging portion 116 for receiving and discharging the rails are disposed on the body 11 of the power supply car 10, an opening 1131 for passing the rails is disposed on the end wall 113 of the body 11 of the power supply car 10, wherein the shape of the opening 1131 may be any shape such as a circle, a quadrangle, or a shape matching the cross-sectional shape of the rails, as long as the rails can pass through, which is not limited in this embodiment.
Optionally, the power-taking member 121 has a power-taking unit 1211, and the power-taking unit 1211 is connected to a contact line when the power supply train 10 is in operation.
Specifically, the power-taking unit 1211 is made of a conductive material, and when the power supply train 10 operates, the power-taking unit 1211 is lifted to be connected with a contact net for electrification, so that the power-taking unit 1211 takes power from the contact net to provide electric energy for the rail transport train set.
In one embodiment, the power supply unit 1211 is a pantograph.
Specifically, the pantograph structure is generally an arch structure including an underframe 111, a lower support, an upper support and a pantograph head, and the pantograph can obtain power from a contact network with rated voltage, such as power supply of an electrical system of a whole train rail transport train set, and meanwhile, the pantograph also has the function of converting kinetic energy of a train into electric energy through a regenerative braking system of the train set and feeding the electric energy back to the contact network to supply to other online train sets, so that the pantograph plays a role of a bidirectional transfer hub.
Optionally, the ceiling 114 is trapezoidal.
Specifically, in order to facilitate the installation of the pantograph, the ceiling 114 may be trapezoidal so that the top thereof is flat, or the ceiling 114 may be rectangular.
Optionally, the power supply vehicle 10 further includes a generator assembly, the generator assembly is located in the vehicle body 11, and the rail transportation vehicle body 11 is selectively electrically connected to the generator assembly.
Specifically, through set up generator assembly on power supply car 10 automobile body 11, make generator assembly become stand-by power supply, when can't get the electricity from the contact net because of power supply assembly 12 or external factors, can provide the electric energy for rail transport vechicle group through generating set price, like this, stability when can improving the operation of rail transport vechicle group.
Further, in order to prevent that the rail transport vehicle group from causing too big impact when transporting because of receiving outside striking, can all set up coupling buffer 15 at the front and back end of power supply car 10 and rail transport vehicle body, wherein, coupling buffer 15 is general structure among the prior art, and to this, this embodiment is no longer repeated.
According to the steel rail transport vehicle set provided by the embodiment of the invention, the rail transport vehicle body and the power supply vehicle for supplying electric energy to the rail transport vehicle body are arranged, the power supply vehicle comprises a vehicle body, and a power supply assembly and a grounding device which are positioned on the vehicle body, the output end of the power supply assembly is electrically connected with the rail transport vehicle body, the grounding device is connected below the vehicle body, the grounding device can stretch out and retract along the direction vertical to the ground, when the power supply vehicle starts to operate, the other end of the grounding device firstly stretches out to be connected with a steel rail on a track, and the input end of the power supply assembly is connected with a contact net, so that the power supply vehicle supplies electric. Through setting up earthing device, when the power supply operation, earthing device contacts with the rail on the track in advance, can make the electricity that receives from the contact net not pass through the bearing in the automobile body axle box when the backward flow, protects the bearing, prolongs the life of bearing, makes the electricity of backward flow transmit the rail through earthing device and leads to the ground again to satisfy the power consumption demand of rail transport vechicle group in the in-process of traveling.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
