Description

Technical Field

[0001] The invention relates to the field of material cleaning and processing equipment, and in particular to a device for cleaning a compartment. Background Art

[0002] Ports, power plants, mining and smelting companies purchase a large amount of block or powdered mineral resources as raw materials, such as coal, during the production process. This type of bulk raw materials is mainly transported by train or heavy trucks in bulk purchases. During transportation, due to moisture and vibration, the bulk materials are generally tightly attached to the carriage. After unloading, some of the materials cannot be unloaded cleanly, and generally adhere to the bottom of the carriage or the side of the carriage, requiring manual cleaning. For example, when manually cleaning a train transporting coal car, the cleaning staff opens the door of the train carriage, enters the carriage, and uses a shovel and a broom to sweep the remaining materials in the carriage, and then sweeps them out of the carriage door and scatters them beside the train track. After getting off the train, the cleaning staff reseals the side door of the train carriage, and then collects and transports the coal scattered beside the train track. This manual cleaning method is not only inefficient, but also has a harsh working environment and is unsafe. The market urgently needs an intelligent cleaning equipment to complete the cleaning of the remaining materials in the carriage.

[0003] Patent CN 109131414B describes a device for cleaning train carriages, which uses a disc brush and a roller brush to clean up the residual materials and collect them in a storage bin. Although this solution can complete the cleaning and collection of residual materials, it has the following defects: 1. It can only clean the residual materials at the bottom of the car, but cannot clean the residual materials adhering to the side of the car; 2. The collected residual materials cannot be discharged continuously out of the carriage, and the cleaning device must be lifted out of the carriage after each carriage is cleaned and then the collected residual materials are unloaded; 3. In order to prevent dust from being generated during cleaning, this solution needs to set up a spray mechanism and increase the spray water channel. Although water spraying can reduce dust, it will also cause some materials with high viscosity to become more sticky after water spraying, and it is more likely to stick to the carriage wall and cannot be cleaned cleanly.

[0032] Reference Figure 1 As shown, the device for cleaning the compartment includes:

[0033] The vehicle side cleaning mechanism comprises a frame 100 and at least one vertical brush 200, each vertical brush 200 is vertically arranged at the lower end of the frame 100, and a vertical brush driving device for driving each vertical brush 200 to rotate is arranged on the frame 100;

[0034] The underbody cleaning mechanism comprises at least one horizontal brush 300 and a horizontal brush driving device for driving each horizontal brush 300 to rotate, wherein the horizontal brush 300 is horizontally arranged at the lower end of the vertical brush 200;

[0035] The negative pressure suction mechanism includes a suction tube 410 and a suction nozzle 420 . The suction nozzle 420 is connected to the suction tube 410 , and the opening of the suction nozzle 420 faces the horizontal brush 300 .

[0036] During the cleaning operation, the robot arm coupling device 110 on the frame 100 is connected to the external robot arm, and driven by the robot arm, the cleaning device moves in the compartment to perform the cleaning operation.

[0037] When cleaning, the vertical brush driving device drives the vertical brush 200 to rotate and clean the materials adhering to the side of the vehicle. The horizontal brush driving device drives the horizontal brush 300 to rotate and clean the materials adhering to the bottom of the vehicle. The suction pipe 410 is connected to the external negative pressure suction device. After the materials are cleaned, they are transported to the outside of the vehicle through the suction nozzle 420 and the suction pipe 410 under the action of negative pressure.

[0038] like Figures 2 to 5 As shown, the number of the vertical brushes 200 is at least one pair, each pair includes two vertical brushes 200, and the two vertical brushes 200 of each pair are relatively vertically arranged on both sides of the lower end of the frame 100. The number of the horizontal brushes 300 is one pair, and the two horizontal brushes 300 are arranged in parallel and horizontally between the two vertical brushes 200, and the opening of the suction nozzle 420 faces the middle position of the two horizontal brushes 300.

[0039] A vertical brush 200 is installed on each side of the lower end of the frame 100. During the cleaning operation, driven by the vertical brush driving device, the two vertical brushes 200 of each pair rotate toward the center of the cleaning device at the same time, and the rotation direction is to sweep the cleaned residual material toward the moving direction of the cleaning device. Figure 4 In this way, the vertical brushes 200 on both sides can sweep the materials adhering to the inner side of the carriage and throw them forward so that the suction nozzle 420 can suck away the materials on the path.

[0040] The two horizontal brushes 300 at the bottom of the cleaning device also rotate toward the center of the cleaning device, sweeping the residual materials at the bottom of the carriage and the residual materials swept by the vertical brushes 200 into the suction nozzle 420 in the middle of the cleaning device. Figure 3 As shown, the suction nozzle 420 is connected to the suction pipe 410. During the cleaning operation, the cleaning device is connected to an external negative pressure suction mechanism, and negative pressure is generated at the suction nozzle 420. The residual material swept into the middle of the cleaning device by the horizontal brush 300 is sucked into the suction nozzle 420 under the action of the negative pressure and discharged out of the car through the suction pipe 410.

[0041] Generally speaking, a carriage is 2-3 meters wide, such as a train carriage, and the width of different models of carriages is also different. In order to make the cleaning device applicable to a variety of models of carriages and not too bulky, the cleaning device is designed to have a fixed width, which is lower than the width of the carriage, and uses multiple back and forth cleaning operations to cover all the areas that need to be cleaned in the carriage.

[0042] For example, when cleaning a train carriage, the cleaning device can first move in one direction along the length of the train to perform cleaning operations. After cleaning in one direction, the cleaning device only needs to be moved in the width direction of the carriage by the width of the cleaning device, and then moved in the opposite direction to the direction just cleaned to perform cleaning operations. At this time, since the moving direction of the cleaning device has changed, it is only necessary to reverse the rotation direction of the two vertical brushes 200 at the same time to ensure that the materials on the side of the car are thrown by the vertical brushes 200 in the direction of movement of the cleaning device. That is, the cleaning direction has changed, and the cleaning device does not need to rotate, and it is only necessary to change the direction of the vertical brushes 200.

[0043] When the cleaning device reaches the end of the carriage and moves along the width direction of the carriage, the short side of the carriage side can also be cleaned. This cleaning device can clean the four insides of the carriage and the ground by only changing the moving direction and the turning direction of the vertical brush 200, and is not limited by the type of carriage.

[0044] Because the materials are generally left at the lower part of the carriage, in this embodiment, in order to simplify the structure of the cleaning device, the height of the vertical brush 200 is lower than the height of the carriage. Of course, the height of the vertical brush 200 can also be designed to be equal to the height of the carriage according to actual conditions.

[0045] like Figure 8 and Fig. 9As shown, there are two pairs of vertical brushes 200 , which are arranged relatively parallel to each other at the lower end of the frame 100 , and a horizontal brush 300 is arranged between each pair of vertical brushes 200 .

[0046] The characteristic of this embodiment is that the vertical brushes on both sides of the frame 100 are changed from one to two vertical brushes 200. Fig. 9 As shown, during cleaning, each vertical brush 200 rotates toward the center, so that the remaining material on the side of the vehicle falls to the center of the cleaning device, and then passes through the horizontal brush 300 and is sucked away near the suction nozzle 420. In this way, no matter which direction the cleaning device moves, the rotation direction of the vertical brush 200 does not need to be changed.

[0047] The vertical brush 200 includes a vertical brush shaft 210 and a vehicle side material loosening and cleaning structure arranged on the vertical brush shaft 210 . The vertical brush driving device is transmission-connected to the vertical brush shaft 210 to drive the vertical brush shaft 210 to rotate.

[0048] The vertical brush driving device drives the vertical brush shaft 210 to rotate, and the vehicle side material loosening and cleaning structure set on the vertical brush shaft 210 rotates with the vertical brush shaft 210. During the rotation, the structure of the compacted material on the vehicle side is destroyed, the residual material attached to the vehicle side is loosened, and it is cleaned off the vehicle side.

[0049] In this embodiment, the vehicle side material loosening and cleaning structure includes a vertical shaft brush 220 and a vertical shaft steel wire 230 . The vertical shaft brush 220 and the vertical shaft steel wire 230 are alternately distributed on the vertical brush shaft 210 and are spirally arranged on the vertical brush shaft 210 .

[0050] The vertical brush 220 can loosen the compacted material and destroy the structure of the compacted material when the vertical brush shaft 210 rotates, and the vertical brush 220 cleans the carriage. After the material falls to the bottom of the carriage, it is sucked away by the suction nozzle 420.

[0051] like Figure 7 As shown, the horizontal brush 300 includes a horizontal brush shaft 310 and a vehicle bottom material loosening and cleaning structure arranged on the horizontal brush shaft 310 , and the horizontal brush driving device is transmission-connected to the horizontal brush shaft 310 to drive the horizontal brush shaft 310 to rotate.

[0052] The horizontal brush shaft 310 is driven to rotate by the horizontal brush driving device, and the material loosening and cleaning structure at the bottom of the vehicle loosens the material attached to the bottom of the vehicle. After the material at the bottom of the vehicle is loosened, the suction nozzle 420 can suck it away.

[0053] In this embodiment, the vehicle bottom material loosening and cleaning structure includes a transverse brush 320 and a transverse steel wire 330, which are alternately distributed on the transverse brush shaft 310. The transverse brush 320 and the transverse steel wire 330 are spirally arranged from both ends of the transverse brush shaft 310 to the middle, forming a V-shaped structure.

[0054] Similarly, the horizontal axis wire 330 loosens the hardened material, destroys the hardened material structure and crushes the large pieces of residual material, so that the adhered material is separated from the bottom of the vehicle. The horizontal axis brush 320 sweeps the separated residual material particles and dust to the middle of the cleaning device.

[0055] The horizontal brush 320 and the horizontal steel wire 330 are spirally arranged from both ends of the horizontal brush shaft 310 to the middle, forming a V-shaped structure. This arrangement allows the horizontal brush 300 to sweep the materials at both ends of the horizontal brush 300 toward the center of the horizontal brush 300 when rotating, so that the swept materials are closer to the suction nozzle 420 located in the middle of the cleaning device, so that they are more easily sucked away.

[0056] Furthermore, a group of scrapers 340 are provided on opposite sides of the transverse brush shaft 310. The scrapers 340 are arranged in parallel with the transverse brush 320 and the transverse steel wire 330, and are spirally arranged from both ends of the transverse brush shaft 310 to the middle, forming a V-shaped structure.

[0057] Compared with the horizontal brush 320 and the horizontal wire 330, the scraper 340 can better sweep and collect the residual materials toward the center direction of the horizontal brush 300. At the same time, a relatively closed area is formed between the scraper 340 and the bottom of the vehicle during cleaning, so that the negative pressure near the suction nozzle 420 is greater and the suction force is stronger.

[0058] Furthermore, a dust hood 500 is provided outside the suction nozzle 420 , and an opening of the dust hood 500 is provided above the two horizontal brushes 300 .

[0059] The dust hood 500 can increase the suction area of ​​the suction nozzle 420. The dust generated when the horizontal axis brush 320 is cleaning is sucked away synchronously through the dust hood 500 connected to the suction nozzle 420, making the cleaning process more environmentally friendly.

[0060] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
