Embodiment Construction
[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0030] Such as figure 1 , 2 As shown, a power supply device for road-rail intermodal trucks of the present invention includes: a four-degree-of-freedom connection seat 1 and an electric plug body 11, the connection seat 1 is fixedly connected to the upper part of the coupler in the middle of the truck compartment through a base 2, and the electric The plug body 11 includes a connection end and a plug end.
[0031] The four degrees of freedom of the connecting seat are realized by the following structure:
[0032] The connecting seat has a first joint part 3 connected to the base 2, the first joint part 3 is provided with a turning bearing 6 inside, and a turning spring 7 is connected to the outside, so that the connecting seat can swing left and right when the train turns;
[0033] The connecting seat has a second joint part 4, which is pro...

The invention relates to a highway-railway combined transport truck energization device, which comprises a four degree-of-freedom connection base and an electrical plug body, wherein the connection base is fixedly connected to the upper part of a car coupler in the middle of a freight car through a base; and the electrical plug body comprises a connection end and a plug end. A highway-railway combined transport truck energization method specifically comprises two stages as follows: in order to protect the electrical plug, connection of a mechanical plug is achieved in the first stage; and after the position of the mechanical plug is aligned, connection of the electrical plug is achieved in the second stage. A convex head and a concave head are utilized on the left and the right of the electrical plug respectively; and 'turnround connection' between the train freight cars is permitted, namely after any car turns around for 180 degrees, the electrical plug can be freely connected. Four degrees of freedom can be achieved by the energization device; by the energization method, mechanical connection and electrical connection are achieved through the two stages respectively; and the electrical plug is protected.
Description
technical field [0001] The invention relates to an electrification device and an electrification method for road-railway trucks, belonging to the technical field of logistics transportation. After the truck is electrified, it provides power for driving the traction arm of the road-railway truck and locking the traction pin of the truck, and provides braking power for speeding up the road-railway truck. Provide refrigeration power for cold chain transportation. Background technique [0002] With the development of the logistics and transportation industry, the demand for combined domestic road and rail transportation has become urgent, and it is urgent to increase the speed of trucks. If a train freight car adopts pneumatic brakes, the freight car near the locomotive brakes first, and the brake of the freight car far away from the locomotive lags behind, which limits the speed of the freight car. [0003] Cold chain train transportation is a worldwide issue. China’s railway ...
