[0002] When transporting solid bulk materials by train, the materials are generally transported to the train carriages through transfer devices such as grab buckets. Therefore, after the transfer is completed, multiple protrusions of the materials will be formed on the top side of the material pile in the train carriage, which takes up space and easily causes the materials to spill, and cannot meet the relevant requirements of railway transportation. Therefore, the materials need to be flattened. The existing method is usually to flatten the materials manually, which increases the workload of on-site staff and reduces loading efficiency. In addition, there are also special flattening equipment such as mechanical arms to flatten the materials, but the existing flattening equipment has a complex structure and can only flatten each train carriage in turn when the train is stopped, which still reduces the efficiency of train transportation and leads to waste of production capacity.

DETAILED DESCRIPTION
[0013] With reference to the accompanying drawings, the specific implementation is as follows:
[0014] A material leveling device for a railway carriage containing solid bulk materials, such as Figure 1 As shown, it specifically includes two flattening devices, wherein the first flattening device 2 is located on the side of the second flattening device 3 away from the forward direction of the train, and the two flattening devices both include a gantry 6 spanning above the rails.
[0015] like Figure 2 , 3 As shown, a lifting power device 7 is connected to the middle of the horizontal bar on the top side of the gantry 6. The lifting power device 7 extends vertically downward. The bottom end of the lifting power device 7 is connected to the lifting platform 9. The lifting power device 7 is an electric push rod. The vertical pole parts on both sides of the gantry 6 are provided with guide rails 8. Pulleys that move along the guide rails 8 are respectively installed at both ends of the lifting platform 9 along the length direction. An upper limit sensor 11 and a lower limit sensor 12 are also installed on the gantry 6.
[0016] like Figure 1 As shown, an electric control device 5 and a plurality of carriage positioning sensors 4 are installed on the outer sides of the two gantries 6. The electric control device 5 can control the lifting power devices 7 of the two flattening devices to perform telescopic movements according to the detection signals of the plurality of carriage positioning sensors 4 for the train carriage 1. The electric control device 5 can also control the lifting power device 7 to drive the lifting platform 9 to move to the upper limit position or the lower limit position according to the detection signals of the upper limit sensor 11 and the lower limit sensor 12 for the lifting platform 9.
[0017] like Figure 2 , 3 As shown, a plow-shaped flattening plate 13 is installed on the bottom side of the lifting platform 9 of the first flattening device 2 through a plurality of hinge supports 10, and a comb-shaped flattening plate 14 is installed on the bottom side of the lifting platform 9 of the second flattening device 3 through a plurality of hinge supports 10. The length directions of the plow-shaped flattening plate 13 and the comb-shaped flattening plate 14 are both arranged along the width direction of the train carriage 1. When the lifting platform 9 is located at the lower limit position, the bottom sides of the plow-shaped flattening plate 13 and the comb-shaped flattening plate 14 can contact the top side of the material pile in the train carriage 1 and flatten the material.
[0018] The plow-shaped flattening plate 13 has two inclined surfaces on the side facing away from the train's forward direction. The two inclined surfaces can cooperate to guide the material to flow from the middle position in the width direction of the train car 1 to the two sides to prevent excessive accumulation of material in the middle position of the train car 1. The bottom end of the comb-shaped flattening plate 14 is provided with a plurality of comb teeth at intervals along the length direction. The plurality of comb teeth can cooperate to loosen the material and thereby completely break up the protrusions on the top side of the material pile.
[0019] Working process: When the train has not reached the location of the material flattening device, the lifting platforms 9 of the two flattening devices are both at the upper limit position. When the train moves towards the material flattening device, it will be detected in turn by multiple car positioning sensors 4, and the detection signal will be transmitted to the electronic control device 5. The electronic control device 5 then judges the actual position of the train car 1. When the train car 1 reaches the starting working position of the first flattening device 2, the electronic control device 5 extends the lifting power device 7 of the first flattening device 2 until the lower limit sensor 12 of the first flattening device 2 detects the lifting platform 9 and feeds back a signal to the electronic control device 5. Then, the lifting power device 7 of the first flattening device 2 stops extending. At this time, the lifting platform 9 of the first flattening device 2 reaches the lower limit position, and the plow-shaped flattening plate 13 begins to flatten the material once.
[0020] When the train carriage 1 continues to move to the stop working position of the first flattening device 2, the electronic control device 5 shortens the lifting power device 7 of the first flattening device 2 until the upper limit sensor 11 of the first flattening device 2 detects the lifting platform 9 and feeds back a signal to the electronic control device 5, and then the lifting power device 7 of the first flattening device 2 stops shortening. At this time, the lifting platform 9 of the first flattening device 2 reaches the upper limit position, the plow-shaped flattening plate 13 separates from the material, and one-time flattening is completed.
[0021] When the carriage positioning sensor 4 detects that the train carriage 1 has reached the starting working position of the second flattening device 3, the electronic control device 5 extends the lifting power device 7 of the second flattening device 3 until the lower limit sensor 12 of the second flattening device 3 detects the lifting platform 9 and feeds back a signal to the electronic control device 5, and then the lifting power device 7 of the second flattening device 3 stops extending. At this time, the lifting platform 9 of the second flattening device 3 reaches the lower limit position, and the comb-shaped flattening plate 14 starts to flatten the material for a second time.
[0022] When the train carriage 1 continues to move to the stop working position of the second flattening device 3, the electronic control device 5 shortens the lifting power device 7 of the second flattening device 3 until the upper limit sensor 11 of the second flattening device 3 detects the lifting platform 9 and feeds back a signal to the electronic control device 5, and then the lifting power device 7 of the second flattening device 3 stops shortening. At this time, the lifting platform 9 of the second flattening device 3 reaches the upper limit position, the comb-shaped flattening plate 14 separates from the material, and the secondary flattening is completed.
[0023] The above two flattening processes complete the flattening of the materials in the carriage, so that the materials inside the carriage meet the relevant requirements of railway transportation, and all the train carriages of a train can be flattened during the travel of the train, greatly improving the efficiency of train transportation.
