Description

Technical Field

[0001] This invention belongs to the technical field of coal leveling equipment, specifically relating to a traveling coal leveling device, system, and method. Background Technology

[0002] In the railway transportation of bulk materials such as coal and ore, the surface smoothness of the material after loading is a key indicator affecting transportation safety, economic efficiency, and environmental protection. Currently, the commonly used loading method both domestically and internationally is a rapid loading station combined with excavator assistance. However, this process has an inherent flaw: when the material (especially pulverized coal) falls into the car, its surface exhibits irregular undulations, such as a "hump" or "wave," ultimately leading to material spillage during transportation, causing environmental pollution and economic losses.

[0003] The current method of leveling coal involves manually shoveling it with iron shovels or requiring the train to stop and level it before restarting. This is time-consuming and labor-intensive, severely restricting transportation efficiency and posing safety hazards. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a traveling coal leveling device, system, and method, which not only achieves automatic leveling of the material surface but also ensures efficient transportation of pulverized coal.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a traveling coal leveling device, including a guide rail, a first support slidably connected to the guide rail via a power mechanism, a lifting mechanism provided on the first support, a scraper flexibly connected to the bottom of the lifting mechanism, and several radars also provided on the first support.

[0006] Furthermore, the power mechanism includes a motor, which is fixedly connected to the first bracket. The output end of the motor is provided with a power wheel. The bottom of the first bracket is also provided with a rotating shaft. A transmission wheel is fixedly sleeved on the rotating shaft. The transmission wheel and the power wheel are meshed and connected. Rotating wheels are also provided at both ends of the rotating shaft. The rotating wheels are connected to the guide rail.

[0007] Furthermore, the bottom of the first bracket is provided with multiple rotating shafts, and a transmission gear is also sleeved on the rotating shaft. A rack is provided on the guide rail, and the transmission gear is meshed with the rack.

[0008] Furthermore, a connecting plate is provided between the rotating shafts, and a connecting seat is also sleeved on the rotating shaft. The connecting seat is fixedly connected to the connecting plate. The connecting plate is L-shaped, and a slider is also provided on the side of the connecting plate. The slider is slidably connected to the side of the guide rail.

[0009] Furthermore, the first bracket is provided with multiple lifting mechanisms, each lifting mechanism including a second bracket, which is vertically and fixedly connected to the first bracket. The second bracket is also provided with a sliding groove, in which a lifting rod is slidably connected. The second bracket is also fixedly connected with a third bracket, which is provided with a cylinder. The output end of the cylinder is connected to the lifting rod, and the bottom of the lifting rod is provided with a scraper.

[0010] Furthermore, the bottom of the lifting rod is provided with a flexible connector, the flexible connector including a mounting base, the mounting base being fixedly connected to the bottom of the lifting rod in a cross shape, the bottom of the lifting rod being hinged with a mounting rod, the mounting rod having a slot, and the scraper being fixed to the mounting rod through the slot; Both ends of the mounting base are provided with springs, and the ends of the springs are connected to the mounting rod.

[0011] Furthermore, the various scrapers are of different sizes.

[0012] Furthermore, the guide rail is supported by several columns.

[0013] A traveling coal leveling system, based on a traveling coal leveling device, includes, The power module includes a power mechanism and a lifting mechanism; The monitoring module is used to monitor the dimensions, speed, and position of the coal wagons to be leveled. The control module is used to control the speed of the motor and the lifting and lowering state of the cylinder.

[0014] A method for leveling coal seams while moving, based on a moving coal seam leveling system, includes the following steps: The selection of scraper involves monitoring the dimensions of the coal car to be leveled as it enters the car and determining the scraper to be used. When the front of the coal-carriage passes the scraper by 0.5m, the control module controls the motor to move forward and simultaneously controls the scraper to fall, ensuring that the scraper's speed is greater than the speed of the coal-carriage. The scraper scrapes the coal in the coal-carriage towards the front and fills both ends until the scraper reaches the very front of the coal-carriage. Then, the motor controls the scraper to start moving in the opposite direction. After a set time, it moves back in the direction of the coal-carriage, this time at a speed less than the speed of the coal-carriage, until the rear of the coal-carriage arrives, completing the scraping of the remaining coal. When the scraper approaches the very rear of the coal-carriage, it is lifted to prepare for the next cycle.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention adopts a moving coal leveling method, which not only ensures the flatness of the material surface in the entire carriage, but also ensures the material transportation efficiency. 2. The scraper of the present invention adopts a flexible connection method to avoid rigid collisions during operation; and the use of scrapers of different sizes improves the compatibility of the device; the present invention adopts the setting of connecting plate and transmission gear to ensure the stability and synchronization of the overall operation of the coal leveling device.
