Description

Technical Field

[0001] This utility model relates to the field of material leveling technology for loading vehicles, and in particular to a mobile train material leveling device. Background Technology

[0002] The railway transportation of metallurgical raw materials requires that the materials in the freight train cars be evenly distributed laterally and that the longitudinal load not exceed the prescribed allowable value. However, during the loading process into the train cars, bulk materials can easily form a cone-shaped pile. Furthermore, coking coal and some metallurgical raw materials are affected by climatic conditions such as temperature and humidity, which can lead to uneven distribution and cause the single axle load of the train to exceed the limit.

[0003] The existing leveling operations for freight trains have undergone mechanization and intelligent reforms. Most existing leveling cars are fixed, with structures similar to overhead cranes or gantry cranes. This involves significant investment and requires repeated installation on multiple tracks, making it difficult to maximize the utilization of engineering and human resources. Traditional manual leveling methods are even more labor-intensive, time-consuming, and pose significant safety hazards, with uncontrollable leveling quality.

[0004] Therefore, it is necessary to invent a mobile train leveling device to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a mobile train leveling device to address the above-mentioned problems, thereby solving the technical problems that traditional train leveling equipment is mostly fixed, resulting in repetitive setups and difficulty in maximizing the utilization of engineering and human resources.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A mobile train leveling device includes a main frame, a moving structure, a lifting device, and a leveling head. The main frame has legs arranged alternately on both sides of its lower part, and the moving structure is provided under each of the legs. The lifting device is installed in the middle of the main frame, and the leveling head is installed on the lifting device. The lifting device can drive the leveling head to move up and down, and the leveling head has the function of leveling materials.

[0008] Furthermore, it also includes a detection device that can detect the positions of the front and rear of the carriage.

[0009] Furthermore, each side of the lower part of the main frame is provided with a front support leg and a rear support leg, and the flat material head is located in the middle between the front support leg and the rear support leg; the detection device includes a front probe and a rear probe, the front probe is mounted on the front support leg, and the rear probe is mounted on the rear support leg.

[0010] Furthermore, the moving structure is a tracked moving structure, and the inner front leg and rear leg are both connected to the tracked moving structure.

[0011] Furthermore, the lifting device includes a fixed frame, a lifting frame, a lifting transmission structure, and a first driving device. The fixed frame is mounted on the main frame, the lifting frame is mounted on the fixed frame, the lifting transmission structure is mounted on the lifting frame, the first driving device drives the lifting transmission structure to lift and lower, and the flat material head is mounted at the lower end of the lifting transmission structure.

[0012] Furthermore, the flat material head includes a cover, a flat material rod, and a second driving device. The cover is installed at the lower end of the lifting device, the flat material rod is rotatably installed at the lower part of the cover, and the second driving device can drive the flat material rod to rotate.

[0013] Furthermore, the flat bar is a double-bladed spiral flat bar, with spiral blades of opposite spiral directions on both sides of the flat bar.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] 1. In use, the main frame straddles the train car via outriggers. A movable structure is installed at the bottom of each outrigger, allowing the machine to move longitudinally along the rails. A lifting device is fixed in the middle of the main frame, with a leveling head suspended at its lifting end. During operation, the movable structure first drives the entire machine synchronously towards the car to be leveled. The lifting device lowers the leveling head to the height of the material cone. Then, the machine maintains a constant speed, and the leveling head cuts into the material pile, using its rigid lower edge to push the material at the cone's apex outwards, rapidly reducing the pile angle of the car's transverse cross-section and ultimately forming a uniform, flat material surface along the entire length of the car. This eliminates the need to repeatedly construct fixed gantry cranes at each unloading line, reducing initial investment. Car leveling is transformed from manual to mechanized, improving efficiency. It solves the problems of redundant construction and low resource utilization caused by traditional fixed leveling equipment ("one machine per rail"), as well as the low efficiency, uncontrollable quality, and significant safety hazards associated with manual leveling.

[0016] 2. The detection device of this utility model can detect the position of the front / rear of the car in real time, and automatically start and stop the leveling operation to ensure that the leveling head only works within the car body and avoids empty travel and collision accidents.

[0017] 3. This utility model uses a double-bladed spiral flat material bar with spiral blades rotating in opposite directions on both sides. When rotating, the material at the top of the middle cone is pushed to both sides of the carriage. In one pass, the material surface at the top of the "Λ" shape can be flattened into a "—" shape, which further improves the material leveling efficiency. Attached Figure Description
