[0038] The technical scheme of the utility model will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0039] As Figures 1 to 6 shown, one embodiment of the utility model provides a gantry type multifunctional coal leveling device, which comprises a gantry frame 1, a first coal leveling mechanism 2, a second coal leveling mechanism 3 and a driving mechanism 4. The first coal leveling mechanism 2 and the second coal leveling mechanism 3 are arranged on the gantry frame 1 along the front-rear direction at intervals and can slide on the gantry frame 1 along the up-down direction. The first coal leveling mechanism 2 and the second coal leveling mechanism 3 are both correspondingly provided with the driving mechanism 4 for driving them to slide on the gantry frame 1. The first coal leveling mechanism 2 is used for scraping the coal pile in the car compartment to deviate the load, and the second coal leveling mechanism 3 is used for spreading and compacting the surface of the coal pile in the car compartment.

[0040] The gantry type multifunctional coal flattening device can compact, flatten and scrape the coal in the carriage. The gantry type multifunctional coal flattening device comprises a gantry frame 1, a first coal flattening mechanism 2, a second coal flattening mechanism 3 and a driving mechanism 4. The gantry frame 1 comprises a crossbeam 11 and a column 12 on both sides of the crossbeam 11, and a passage for the carriage to pass through is formed below the gantry frame 1. The carriage is generally a train carriage, and the train track is arranged below the gantry frame 1. The first coal flattening mechanism 2 and the second coal flattening mechanism 3 are slidingly arranged on the gantry frame 1, and the first coal flattening mechanism 2 is arranged in front of the second coal flattening mechanism 3. The first coal flattening mechanism 2 and the second coal flattening mechanism 3 are both correspondingly provided with the driving mechanism 4, that is, the sliding of the first coal flattening mechanism 2 and the second coal flattening mechanism 3 on the gantry frame 1 is independently driven, and they do not interfere with each other. In use, the driving mechanism 4 of the first coal flattening mechanism 2 drives the first coal flattening mechanism 2 to slide on the gantry frame 1 in the up-down direction, so that the first coal flattening mechanism 2 can extend into the train carriage and scrape the coal in the train carriage, and the first coal flattening mechanism 2 can be away from the train carriage, so that the train carriage can pass through the gantry frame 1; the driving mechanism 4 of the second coal flattening mechanism 3 drives the second coal flattening mechanism 3 to slide on the gantry frame 1 in the up-down direction, so that the second coal flattening mechanism 3 can extend into the train carriage and flatten and compact the coal in the train carriage, and the second coal flattening mechanism 3 can be away from the train carriage, so that the train carriage can pass through the gantry frame 1.

[0041] During operation, when there is an issue of uneven loading on the coal pile inside the train car beneath the gantry frame 1, the driving mechanisms 4 of the first and second coal leveling mechanisms 2 and 3 can lower and extend into the train car. The first coal leveling mechanism 2 first addresses the uneven loading of the coal pile inside the train car. After the first coal leveling mechanism 2 resolves the uneven loading issue, the second coal leveling mechanism 3 then flattens and compacts the surface of the coal pile inside the train car to ensure full load on both sides of the long side of the car and reduce the need for subsequent dust suppressant spraying. When there is no uneven loading issue, the second coal leveling mechanism 3 can simply be lowered and extended into the train car by its driving mechanism 4 to flatten and compact the surface of the coal pile. In certain operating conditions, only the drive mechanism 4 of the first coal leveling mechanism 2 can lower and extend into the train car to scrape the coal pile inside the car, eliminating the need for the second coal leveling mechanism 3 to level and compact the surface of the coal pile. Alternatively, if only the coal pile at the rear of the train car has an uneven load problem, the drive mechanism 4 of the second coal leveling mechanism 3 can first lower and extend into the train car to level and compact the surface of the coal pile. When the unevenly loaded area inside the train car moves under the first coal leveling mechanism 2, the drive mechanism 4 of the first coal leveling mechanism 2 can then lower and extend into the train car to scrape the coal pile at the rear of the train car. If, in actual use, the coal pile at the rear of the train car is heavy, the train car needs to reverse to perform the scraping operation. The above is only a simple example of the working conditions of the gantry-type multi-functional coal leveling device in this embodiment. In actual use, it is not limited to this. The first coal leveling mechanism 2 and the second coal leveling mechanism 3 can be selectively used for operation according to the actual situation of the coal pile in the train car.

[0042] The gantry-type multi-functional coal leveling device provided in this embodiment can automatically perform scraping, surface leveling, and compaction operations on coal piles inside train carriages. It is applicable to various working conditions, meets various coal leveling requirements, and ensures that the coal loading in train carriages meets relevant requirements. Compared with existing technologies, it eliminates the need for manual operation, reduces labor intensity, increases work efficiency, and enhances safety.
