Description

Technical Field

[0001] The invention relates to the technical field of railway freight transport, and in particular to a single-side cantilever movable railway carriage flat material system. Background Art

[0002] As the transport management unit, the relevant railway departments require that the materials in the carriages be evenly distributed horizontally and that the longitudinal load difference does not exceed the allowable value. However, due to the stacking characteristics of bulk materials, when bulk materials are loaded into train carriages by loading buildings or forklifts, the materials will form a pile with a pointed top in the middle of the carriage. Affected by factors such as humidity, viscosity, and density, the materials in the carriages are uneven and overloaded.

[0003] The existing freight train overload detection and material leveling methods still rely mainly on manual labor: climbing into the carriage when the freight train passes, using a shovel to scrape and level the materials, which takes about 3 to 10 minutes per carriage on average, and about 3 to 10 hours for the entire train. This production method is not only labor-intensive and time-consuming, but also poses great safety hazards to workers who frequently climb, enter, exit, and jump in the carriages. For high-density ore materials, their bulk density is relatively large, and the material loading height is only about 1 / 2 of the height of the carriage, which is more than 1 meter lower than the upper edge of the car side. Ordinary loading chutes cannot extend into the carriage and level the material surface. The material falls only by its own weight, forming an irregular sharp-angled material pile, and the overload phenomenon is particularly prominent.

[0004] There are also a few areas that use mechanical assisted operations, such as fixed gantry and elevated operations. These not only occupy a large area, have high equipment purchase costs, and are difficult to operate and maintain, but also require operations to be performed above the carriages, posing risks such as railway limits and electric shock from high-voltage power grids.

The steel structure support platform 1 includes a basic support platform 11, an I-beam base rail 12, and a traveling rail 6; The I-beam base rail 12 adopts an I-shaped steel structure and is composed of an upper flange 1201, a lower flange 1202, and an intermediate vertical web 1203 connecting the two, with an appearance similar to the Chinese character "工". The I-beam base rail 12 is laid on the basic support platform 11. The traveling rail 6 is installed on the upper surface of the upper flange 1201 of the I-beam base rail 12 using a railway rail.

When the spiral flat material head 5 is folded, the whole is higher than the train carriage. When working, it can be extended into the carriage to perform flat material operations and can be raised and lowered according to the height of the carriage.

[0022] The spiral flattening head 5 adopts a hydraulically driven motor to flatten the material in two directions, i.e., in the length direction and the width direction of the carriage. The length direction depends on the moving speed of the flattening equipment vehicle 2, and the width direction spiral flattening head 5 includes left and right spiral blades 51 that can rotate in two directions to distribute material to the left and right sides of the carriage.

[0025] The steel structure support platform 1 meets the equipment load-bearing and stable operation requirements, and also meets the requirements of the local climate environment such as earthquake resistance, corrosion resistance, etc. In this embodiment, the I-beam base rail 12 is formed by connecting 300-type H-beams, each H-beam is leveled and connected together, the height difference between the front and rear ends of the rail is less than 10mm, and the height difference between the rails on both sides is less than 5mm.

[0026] The whole structure of the flat material equipment is 760 mm away from the minimum limit of the carriage, which meets the railway's requirements for the limit. In this embodiment, the length of the driving rail 6 used to operate the flat material equipment vehicle 2 is approximately equal to the length of two train carriages; A drive integrated box 202 is arranged in the middle of the lower end of the flat material equipment vehicle 2, and a drive shaft 203 is extended from the front and rear of the drive integrated box 202, and the drive shafts 203 extended from the front and rear are respectively connected to the two pairs of track rollers arranged in the front and rear to form a synchronous four-wheel drive.

The chassis of the vehicle body is made of high-quality carbon structural steel, and the steel grade material is uniformly selected as Q355B. Buffer limit baffles are arranged in the front and rear directions, and the anti-drop limit device 13 is used to prevent it from going out of bounds.

[0027] The leveling equipment vehicle 2 is provided with a cab 21, and the operation controller is arranged in the cab 21. Preferably, the cab 21 is arranged at a height that allows the driver to intuitively see the leveled materials in the train track carriage. The cab 21 is also equipped with a manual operation panel, a seat, and air conditioning; the roof of the cab 21 is equipped with a lighting headlight, and a number of cameras are arranged outside the vehicle (such as the front and rear of the roof cab, and the front and rear of the working arm) to ensure that the working conditions of the external carriage can be clearly seen.

The adaptive control algorithm can automatically adjust the control parameters according to the load changes and environmental interference of the boom mechanism, so that the boom mechanism can accurately track the target position. At the same time, in order to improve the movement efficiency of the boom mechanism, the optimal control algorithm can be used to plan the movement trajectory of the boom mechanism so that the boom mechanism can reach the target position in the shortest time.

[0032] For short-distance communication between devices, the Modbus RTU protocol is used, which is simple, reliable, and easy to implement. For long-distance communication, the MQTT protocol is used. MQTT is a lightweight message transmission protocol with the characteristics of low bandwidth and high reliability, which is suitable for long-distance communication of IoT devices.
