Description
Technical Field
[0001] The present application relates to the technical field of cleaning frozen coal in train carriages, and in particular to an automatic cleaning device for cleaning frozen coal in train carriages. Background Art
[0002] Due to the uneven regional distribution of coal in my country, coal-using enterprises rely on train transportation for their economical operation. Winter outdoor temperatures in northern China generally range from -10°C to -30°C. During long-distance train transport, coal often freezes and sticks together, forming frozen coal with a thickness of around 400mm. In severe cases, the entire train car can freeze. Because the frozen coal is hard and tightly attached to the coal carriages, unloading operations are extremely difficult, significantly impacting coal costs and normal production for coal-using enterprises, resulting in human and financial losses.
[0003] Coal-using enterprises widely use manual cleaning and the establishment of greenhouses to clean frozen coal from train coal carriages. Manual cleaning is time-consuming and labor-intensive, with extremely low efficiency. Cleaning a train carriage with 400mm of frozen coal requires a team of workers for three hours. Setting up a greenhouse requires a large initial investment, occupies a large area, and has low overall unloading efficiency. In response to this, some existing technologies use mechanical cleaning methods, which are easy to use and highly operational for handling frozen coal and are worthy of widespread promotion. Currently, cleaning mechanisms for cleaning frozen coal from train coal carriages rely on metal cleaning mechanisms that extend into the carriage, for example, using metal scrapers to forcibly remove frozen and sticky coal. However, in actual applications, these methods suffer from unsatisfactory cleaning effects, difficulty handling severe frozen coal, and the potential for damage to the coal carriages. Therefore, further improvement is needed. Utility Model Content

[0007] By adopting the above technical solution, before cleaning the frozen coal, the control system controls the sliding mechanism to drive the telescopic frame to one side, that is, away from the car body, and then the coal is unloaded by the dumper.

[0039] It should be noted that, in this embodiment, the top of the carriage 1 is open, and the carriage 1 is an open car. The two side walls of the carriage 1 in the length direction can be opened. The carriage 1 is specifically flipped along its own axis in the length direction so that the carriage 1 is tilted after flipping. At this time, the crushing mechanism 6 is used to clean the frozen coal on the tilted carriage 1. The dumping angle of the carriage 1 can be less than 90 degrees, or greater than 90 degrees and less than 165 degrees, so that the top opening of the carriage 1 is tilted upward or tilted downward. However, for the carriage 1 with an inclination angle less than 90 degrees, the side wall of the carriage 1 at the bottom needs to be opened. In this embodiment, a carriage 1 with an inclination angle of 75 degrees is specifically shown. Since the tipping machine 11 is a prior art, no further details are given.

The spacing between the two traveling guide rails 2 is greater than the width of the car body 1, and the longitudinal direction of the traveling guide rails 2 is parallel to the entry direction of the tipping machine 11, that is, the longitudinal direction of the traveling guide rails 2 is parallel to the longitudinal direction of the car body 1. It should be noted that the traveling guide rails 2 are provided in a pit 12 opened on the ground for the installation of the tipping machine 11, and one end of the traveling guide rail 2 extends to one end of the pit 12.

[0041] Reference Figure 2 、 Figure 4 , wherein the telescopic frame 3 is used to drive the traveling door frame 5 to extend into or out of the carriage 1. In this embodiment, the telescopic frame 3 specifically includes a sliding seat 31 that is slidably connected to the two traveling guide rails 2, a plurality of groups of scissor arms 32 arranged crosswise on the sliding seat 31, a top frame 33 arranged on the top scissor arms 32 for the traveling door frame 5 to be installed, and a first driving component 34 arranged on the sliding seat 31 to drive the scissor arms 32 to open and close along the sliding seat 31 to drive the top frame 33 to move up and down, wherein the length direction of the sliding seat 31 is perpendicular to the length direction of the traveling guide rail 2. It should be noted that in order to enable the telescopic frame 3 to drive the crushing mechanism 6 to To enter the carriage 1, in this embodiment, the upper end surface of the sliding seat 31 may be provided with a guide surface, which is inclined upward toward the carriage 1; alternatively, a rotating plate 35 may be rotatably connected to the upper surface of the sliding seat 31.

The provision of the guide surface causes the traveling gantry 5 to tilt, potentially causing a collision while moving along the traveling guide rail 2. To this end, in this embodiment, the rotating plate 35 and the hydraulic rod 351 are specifically provided to enable the telescopic frame 3 to enter the carriage 1 from the bottom up.

[0045] The crushing mechanism 6 is used to clean frozen coal stuck to the inside of the carriage 1 after unloading. It comprises a horizontal spiral drum 61 mounted horizontally on the lifting mechanism 7; two vertical spiral drums 62, one on each side of the horizontal spiral drum 61 and perpendicular to it; a plurality of picks 63 mounted on each of the horizontal and vertical spiral drums 61 and 62; and a third drive assembly 64 and a fourth drive assembly (not shown) that respectively drive the horizontal and vertical spiral drums 61 and 62. The horizontal spiral drum 61 cleans the bottom of the carriage 1, while the vertical spiral drum 62 cleans the sides. The length of the horizontal spiral drum 61 is parallel to the length of the carriage 1, while the length of the vertical spiral drum 62 is perpendicular to the height of the gantry 5. In this embodiment, a drill bit 621 is fixedly attached to the end of the vertical spiral drum 62 near the carriage 1. The end surface and outer wall of the drill bit 621 are provided with cutting edges.
[0046] The lifting frame 71 is provided with a rotating frame 73 protruding therefrom for the horizontal spiral drum 61 to be rotatably connected.

It should be noted that the metal sensor 8 can be provided on both the horizontal spiral drum 61 and the vertical spiral drum 62.
[0048] Furthermore, a plurality of steel wires (not shown in the figure) are provided outside the horizontal spiral drum 61 and the vertical spiral drum 62, which may be wear-resistant and rust-proof galvanized steel wires, so as to clean the floating coal.
[0049] The implementation principle of the automatic cleaning device for frozen coal in a train carriage 1 according to an embodiment of the present application is as follows: before cleaning the frozen coal, the control system is used to control the sliding mechanism 4 to drive the telescopic frame 3 to one side, that is, to place it away from the carriage 1, and then the coal is unloaded by the tipping machine 11. For the frozen coal at this time, the sliding mechanism 4 is started to drive the telescopic frame 3 to slide to the corresponding position. After first descending through the lifting mechanism 7, and under the extension and contraction of the telescopic frame 3, the crushing mechanism 6 is driven to enter the carriage 1 from the bottom, and then the third driving assembly 64 and the fourth driving assembly are driven to respectively drive the horizontal spiral drum 61 and the vertical spiral drum 62 to rotate, and then drive the pick 63 to clean the frozen coal. As the cleaned frozen coal is separated from the carriage 1 under the force, when the bottom wall and side wall of the carriage 1 are seen, since the carriage 1 is made of metal, when the detection head of the metal sensor 8 encounters metal material, electromagnetic induction will occur, generating current, and the detector will emit sound and light signals to prompt that the metal material is detected, and then the corresponding data will be transmitted to the control system to drive the lifting mechanism 7 and the telescopic frame 3 to change the height and horizontal position of the crushing mechanism 6 accordingly, so as to clean the frozen coal at other positions and reduce damage to the inner wall of the coal transport carriage 1.
