In order to solve the above problems, the utility model adopts the following technical proposal:

the utility model provides a freight train is with multi-functional step footboard, includes the main tributary dagger, the welding has the horizontal connecting rod in the middle of the main tributary dagger, the welding has first footboard main tributary dagger top, the welding has the second footboard main tributary dagger below, second footboard lower surface is connected with the third footboard, third footboard upper surface both ends all are hinged and are connected with swing joint board one, second footboard lower surface both ends position all is hinged and is connected with swing joint board two, through the mode interconnect of hinged joint between swing joint board one and the swing joint board two, and the junction is equipped with the convolution spring, swing joint board one and swing joint board two are folding under the effect of convolution spring, upwards draw the third footboard.

Furthermore, one side that third footboard and main tributary dagger are adjacent is equipped with the extension board, be fixed with telescopic machanism on the main tributary dagger, telescopic machanism flexible end is down and the top is on the extension board.

Further, the telescopic mechanism is an electric cylinder which is vertically installed.

Further, the telescopic mechanism is fixed in the main support column.

Further, the first movable connecting plate and the second movable connecting plate are folded towards the middle position of the second pedal under the action of the convolution spring.

Further, first footboard and second footboard structure are unanimous, all include pedal part and coupling part, pedal part is the rectangle structure, the coupling part is isosceles trapezoid structure, isosceles trapezoid structure base aligns and interconnect with the long limit of rectangle structure.

Further, the third pedal comprises a pedal part and a connecting part, wherein the pedal part and the connecting part are both of rectangular structures and have the same length, and the long sides of the pedal part and the connecting part are aligned and connected with each other.

Compared with the prior art, the utility model, following beneficial effect has:

a freight train is with multi-functional step footboard, adopt three laminar step footboards, wherein first footboard and second footboard adopt fixed structure, the third footboard passes through swing joint board one and swing joint board two is fixed, under the third footboard does not receive the condition of external force, through the convolution spring effect, the third footboard returns and contracts in the second footboard below, when needs use, make it stretch out downwards through exogenic action, consequently the third footboard only need return lie in the tire top under the state of contracting can, stretch out when needs are about, go in-process returns and contracts, personnel's upper and lower has been put forward promptly, the safety risk has been reduced again.
