[0003] In the tipping and unloading system of the car tipping machine, the shunting machine usually adopts a fixed boom structure, and the shunting machine usually only uses one empty car line to push the empty car operation. When the shunting machine needs to take into account the pushing operation of two empty car lines (spacing 6.5 meters), the original empty car shunting machine cannot meet the use requirements. In the prior art, solving the problem of pushing cars on two empty car lines usually requires a new set of empty car shunting machine tracks and shunting machine equipment for each empty car railway line. The two sets of shunting equipment require a larger layout space. At the same time, adding shunting equipment will also increase the investment cost. Therefore, this design provides a double-boom car pushing device for a shunting machine to solve the problem that the shunting machine cannot take into account the pushing operation of two empty car lines.

When the main pitching arm 1 is working, the main pitching arm 1 is lowered to a horizontal state, at which time the auxiliary pitching arm 2 is raised to a vertical state, and the auxiliary pitching arm 2 is not working. At this time, the empty open car on the empty car line on one side of the shunting locomotive body 3 can be connected to the main pitching arm 1 through the hook 71 on the top of the main pitching arm 1 in the horizontal state, and the empty open car can be pushed to move. When the auxiliary pitching arm 2 is working, the auxiliary pitching arm 2 is lowered to a horizontal state, at which time the main pitching arm 1 is raised to a vertical state, and the main pitching arm 1 is not working. At this time, the open car on the empty car line on the other side of the shunting locomotive body 3 can be connected to the auxiliary pitching arm 2 through the hook 71 on the top of the auxiliary pitching arm 2, and the empty open car can be pushed to move.

[0061] A main pitch arm 1 and an auxiliary pitch arm 2 are respectively arranged on both sides of the shunting locomotive body 3. The trolley device is provided with two working positions: the main pitch arm 1 is horizontal and the auxiliary pitch arm 2 is vertical, and the main pitch arm 1 is vertical and the auxiliary pitch arm 2 is horizontal.
