Description

Technical Field

[0001] This utility model relates to the field of rail transport equipment technology, specifically an unmanned rail transport vehicle. Background Technology

[0002] Currently, unmanned rail transport vehicles are widely used in mines, ports, and logistics warehousing for automated material transport. However, during actual operation, dust, sand, slag, and other debris easily accumulate on the tracks, especially in harsh environments (such as mines and construction sites), where the problem is more severe. These obstacles increase the resistance of the rail vehicle, and may even cause wheel slippage, derailment, or jamming, seriously affecting transportation efficiency and equipment lifespan.

[0003] Traditional solutions mainly rely on regular manual cleaning or fixed track cleaning devices. However, manual cleaning is inefficient and costly, while fixed cleaning devices cannot adapt to the dynamic operation requirements of track vehicles and have limited coverage. In addition, existing unmanned transport track vehicles usually do not have self-cleaning functions. When they encounter dust or foreign objects on the track, they can only slow down or stop, affecting transport efficiency.

[0004] Therefore, there is an urgent need for an unmanned transport railcar that can automatically clean the tracks, removing dust, sand, and other obstacles from the tracks in real time during operation, thereby improving transport stability and efficiency and reducing maintenance costs. Utility Model Content

[0005] This utility model provides an unmanned transport railcar to at least solve the problem of railcar operation being affected by debris such as track dust and slag in the prior art.

[0006] To achieve the above objectives, this utility model provides an unmanned transport railcar including a carriage, a frame and two train wheels. A cleaning mechanism is provided at the front end of one side of the carriage in the direction of travel. The cleaning mechanism is positioned corresponding to the wheels to clean up the dust and slag on the track when the railcar moves forward.

[0007] Furthermore, the cleaning mechanism includes: a fixed frame, which includes a first horizontal plate and a second horizontal plate, with a vertically connected connector between the first horizontal plate and the second horizontal plate. The connector has multiple screw holes so that the first horizontal plate and the second horizontal plate can be fixed to the front end of the carriage through the connector; two slag-shoveling components, which are respectively set on the first horizontal plate at the positions corresponding to the two train wheels to remove slag from the track; and a water spraying component, which includes a water tank and two nozzles. The water tank is set between the first horizontal plate and the second horizontal plate, and the two nozzles are set on the second horizontal plate and are respectively vertically corresponding to the positions of the two slag-shoveling components.

[0008] Furthermore, the ash-shoveling component is a block structure with a vertical cross-section resembling a right-angled trapezoid. The inclined surface of the ash-shoveling component is the ash-shoveling surface. The bottom surface of the ash-shoveling component fits into the track. The side of the ash-shoveling component opposite to the ash-shoveling surface is provided with a groove that matches the thickness of the first horizontal plate. The groove and the first horizontal plate are provided with corresponding screw holes so that the ash-shoveling component can be detachably installed on the first horizontal plate.

[0009] Furthermore, the first horizontal plate is also provided with limiting plates on both sides at the corresponding slot positions.

[0010] Furthermore, the ash-removing surface is an arc surface, and the arc surface is a concave curved surface.

[0011] Furthermore, the sides of the ash-scraping component are hollowed out.

[0012] Furthermore, the nozzle is rotatably mounted on the second horizontal plate, and the second horizontal plate is provided with a driving component to drive the nozzle to rotate.

[0013] Furthermore, the connector is located at the corner of the carriage, and the connector is L-shaped to provide further lateral fixation at the corner of the carriage.

[0014] The unmanned transport railcar utilizing this invention comprises a carriage, a frame, and two sets of wheels. A cleaning mechanism is located at the front end of one side of the carriage in the direction of travel. This cleaning mechanism, positioned corresponding to the wheels, cleans accumulated dust and slag from the track as the railcar moves forward. This invention effectively solves the problems of increased running resistance and wheel slippage caused by track debris accumulation in traditional unmanned transport railcars during operation. The cleaning mechanism employs a combination of a fixed frame and a dust-shoveling component, automatically removing solid debris such as slag from the track during railcar movement. Simultaneously, it utilizes the dust suppression function of a water spray component to achieve a combined wet and dry cleaning effect. The detachable design of the dust-shoveling component facilitates maintenance and replacement, and the adjustable nozzle adapts to different working conditions. The reinforced design of the L-shaped connector enhances the overall stability of the cleaning mechanism, ensuring reliable operation under harsh conditions. Ultimately, through the synergistic effect of mechanical removal, hydraulic dust suppression, and structural optimization, the unmanned transport railcar significantly improves its operating efficiency and reliability in complex environments such as mines and ports, while simultaneously reducing track maintenance costs.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This utility model discloses an unmanned transport rail vehicle, such as Figures 1 to 6 As shown, the railcar includes a carriage 10, a frame, and two wheels 11. A cleaning mechanism 20 is located at the front end of one side of the carriage 10 in the direction of travel. The cleaning mechanism 20 is positioned corresponding to the wheels 11 to clean the accumulated dust and slag on the track as the railcar moves forward. This design allows the railcar to clean the track while in motion. The cleaning mechanism 20 contacts the dust and slag before the wheels 11, making the railcar move more smoothly and protecting the wheels 11.

[0026] Furthermore, such as Figures 1 to 6As shown, the cleaning mechanism 20 includes a fixed frame 21, which includes a first horizontal plate 211 and a second horizontal plate 212. A vertically connected connector 213 is provided between the first horizontal plate 211 and the second horizontal plate 212, which connects the first horizontal plate 211 and the second horizontal plate 212 into a whole, thereby enhancing the overall stability. The connector 213 is provided with multiple screw holes so that the first horizontal plate 211 and the second horizontal plate 212 can be fixed to the front end of the carriage 10 through the connector 213. The system includes two dust-shoveling components 22, each positioned on the first horizontal plate 211 corresponding to one of the two train wheels 11 to remove slag from the track. A water-spraying component 23 comprises a water tank 231 and two nozzles 232. The water tank 231 is positioned between the first and second horizontal plates 211 to save space and facilitate water storage. The two nozzles 232 are positioned on the second horizontal plate 212, corresponding vertically to the positions of the two dust-shoveling components 22. The water-spraying component 23 can suppress dust generated during operation and also collect dust from the track, facilitating the operation of the dust-shoveling components 22.

[0027] Furthermore, such as Figures 2 to 6 As shown, the ash-shoveling component 22 is a block structure with a vertical cross-section resembling a right-angled trapezoid. The inclined surface of the ash-shoveling component 22 is the ash-shoveling surface 221, which meets the usage requirements. The bottom surface of the ash-shoveling component 22 fits into the track, enhancing the stability of travel. On the side of the ash-shoveling component 22 opposite to the ash-shoveling surface 221, there is a groove 222 that matches the thickness of the first horizontal plate 211. The groove 222 and the first horizontal plate 211 have corresponding screw holes so that the ash-shoveling component 22 can be detachably installed on the first horizontal plate 211. When too much ash accumulates on the ash-shoveling component 22 or after working for too long, the operator can replace the ash-shoveling component 22 for maintenance and cleaning, and replace it with a new ash-shoveling component 22 to avoid affecting normal operation.

[0028] Furthermore, such as Figure 6 As shown, the first horizontal plate 211 is also provided with limiting plates 24 on both sides at the corresponding slot 222 position to prevent the shovel component 22 from swaying left and right when it encounters greater resistance during travel, thereby affecting the movement of the railcar.

[0029] Furthermore, such as Figure 6 As shown, the ash removal surface 221 is an arc surface, which is a concave curved surface. It can bear more ash and slag while reducing the resistance encountered when removing ash and slag.

[0030] Furthermore, such as Figure 6 As shown, the ash-shoveling component 22 has hollowed-out sides to reduce its own weight, thereby reducing material costs and also reducing the travel resistance of the railcar.

[0031] Furthermore, such as Figures 3 to 6 As shown, the nozzle 232 is rotatably mounted on the second horizontal plate 212, and the second horizontal plate 212 is provided with a driving component 25 to drive the nozzle 232 to rotate. Driven by the driving component 25, the nozzle 232 sweeps water up and down, which can assist in cleaning the dust removal component 22, and also has a certain cleaning effect on the track.

[0032] Furthermore, the connector 213 is located at the corner of the carriage 10. The connector 213 is L-shaped to further fix it laterally at the corner of the carriage 10, so as to prevent the fixing frame 21 from shaking when the movement is obstructed, thus affecting the stability.

[0033] In practical use, the operator aligns the slot 222 of the shovel component 22 with the corresponding position on the first horizontal plate 211, engages it at the position defined by the limiting plate 24, and tightens the bolts to secure the shovel component 22. Water is then added to the water tank 231, and after adding an appropriate amount of water, the drive component 25 is started to ensure the nozzle 232 is functioning properly. The railcar operates normally at this time, and during its movement, the nozzle 232 suppresses dust in front of it. The ash and slag on the track agglomerate under the action of the sprayed water and are shoveled up and accumulated on the shovel surface 221 by the shovel component 22. After the railcar stops running, the shovel component 22 is removed for cleaning, and then a new shovel component 22 is replaced to repeat the process.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
