Description

Technical Field

[0001] This application relates to the field of automotive charging equipment, and more specifically, to a power supply rail cleaning device. Background Technology

[0002] The application of rail-guided vehicles (such as RGVs) is becoming increasingly widespread in fields such as mobile charging stations, automated logistics, warehousing, and smart manufacturing. These devices typically obtain power through fixed power supply rails. However, in complex industrial environments, the power supply rails are exposed to the air for extended periods, easily accumulating dust, oil, and other particulate impurities. These contaminants adhere to the rail surface, especially in the contact area between the rail and the power receiver, forming an insulating layer. This increases contact resistance, generates electrical sparks, exacerbates power loss, and can even lead to power outages or equipment damage, severely impacting the equipment's operating efficiency, stability, and safety.

[0003] Currently, the cleaning and maintenance of power supply rails mostly rely on manual periodic wiping or the use of simple cleaning tools. This method is not only inefficient and difficult to guarantee the cleaning effect, but it also needs to be carried out when the equipment is stopped, which affects the continuity of the overall work process.

[0015] The beneficial effects of this application are as follows:

[0016] 1. Highly efficient and automated cleaning: By enabling a mobile carrier (such as an RGV vehicle) to move autonomously on the power supply rail, the cleaning track is in continuous contact with the rail, achieving automated and uninterrupted cleaning of the power supply rail, significantly improving cleaning efficiency and reducing interference with the main operation process.

[0017] 2. Dual cleanup mechanism for better results:

[0018] 2.1 Mechanical cleaning: The cleaning brushes installed on the tracks can effectively scrape and remove stubborn dirt attached to the guide rails through direct contact and friction.

[0019] 2.2 Airflow-assisted cleaning: Unique air-blowing components (such as vortex fans) blow air directionally to the power supply rail through the perforations on the track, instantly blowing away the fine dust and impurities that have just been cleaned away from the contact area, and forming an effective airflow channel with the airflow grooves on the track, preventing dust from adhering again and greatly improving the overall cleaning effect.

[0047] Reference Figure 1-5 ,

[0048] A power supply rail cleaning device includes: a mobile carrier 1, a cleaning track 2, a drive component 3, and an air blowing assembly 4.

[0049] A mobile carrier 1 for moving along the power supply rail is used. A cleaning track 2 is mounted on the mobile carrier 1 and contacts the power supply rail. A drive unit 3 drives the cleaning track 2. The cleaning track 2 has multiple through holes 21 and a mounting area 22 in its center. An air blowing assembly 4 is installed in the mounting area 22, allowing air to flow through the through holes 21 to the power supply rail. The cleaning track 2 also has multiple airflow grooves 23, which connect the through holes 21 to the external environment. The driving direction of the cleaning track 2 is opposite to the moving direction of the mobile carrier 1, resulting in a faster movement speed and better cleaning effect relative to the mobile carrier 1. The mobile carrier 1 is a railcar; for example, if the power supply rail uses an RGV track, the mobile carrier 1 uses an RGV vehicle body.

[0050] By employing the aforementioned technical solution, when the mobile carrier 1 moves along the power supply guide rail, the cleaning track 2 on the mobile carrier 1 contacts the power supply guide rail, thereby directly cleaning dust and impurities on the power supply guide rail, ensuring its cleanliness and preventing power supply efficiency from being affected by dust and impurities. The air blowing component 4 further assists in blowing away the dust and impurities cleaned by the cleaning track 2, improving the effectiveness of the cleaning track 2 in removing dust and impurities from the power supply guide rail. This further enhances the power supply efficiency of the power supply guide rail.

[0051] Specifically, the cleaning track 2 is equipped with a cleaning brush, which is used to contact the power supply guide rail.

[0052] Specifically, a receiving box 5 is installed below the cleaning track 2 in the power supply guide rail. After the cleaning track 2 cleans the dust and impurities on the power supply guide rail, the dust and impurities fall directly into the receiving box 5 for recycling.

[0053] Specifically, in the power supply guide rail, the receiving box 5 is fixed to the moving carrier 1, and the receiving box 5 partially encloses the cleaning track 2; the receiving box 5 is provided with scraper teeth 6, which are located on the side of the cleaning track 2 away from the power supply guide rail; the scraper teeth 6 contact the cleaning brush. The scraper teeth 6 clean the cleaning track 2, keeping it clean and improving the cleaning effect of the cleaning track 2 on the power supply guide rail.

[0054] Specifically, the receiving box 5 and the mobile carrier 1 are detachably connected and fixed together. This facilitates the subsequent disassembly of the receiving box 5 and the emptying of dust and impurities from it. The receiving box 5 and the mobile carrier 1 can be magnetically or bolted together.

[0055] Specifically, the blower assembly includes a connecting frame 41 and a vortex fan 42. The connecting frame 41 is connected to the mobile carrier 1, and the vortex fan 42 is disposed in the installation area 22 and connected to the connecting frame 41. The air inlet direction of the vortex fan 42 is the same as the drive axis direction of the cleaning track 2; the air outlet direction of the vortex fan 42 intersects with the power supply guide rail. By utilizing the vortex fan, air can be more effectively drawn in directly through the side gaps of the cleaning track 2 and directly blown out through the perforations 21 on the cleaning track 2, thus better ensuring the intensity of the outward airflow.

[0056] Specifically, the power supply guide rail includes a driving roller 31 and a driven roller 32 mounted on the moving carrier 1, with the cleaning track 2 wound around the driving roller 31 and the driven roller 32. A driving component 3 is mounted on the moving carrier 1 and is used to drive the driving roller 31 to rotate. The driven roller 32 is detachably connected to the moving carrier 1. This detachable connection of the driven roller 32 facilitates the disassembly of the cleaning track 2, and thus also facilitates its replacement.

[0057] Specifically, the power supply guide rail includes a hinge frame 7 and a rotating shaft 71 on the moving carrier 1; the driven roller 32 is inserted into the rotating shaft 71; the hinge frame 7 is hinged to the moving carrier 1; the rotating shaft 71 is rotatably connected to the hinge frame 7; a control structure exists between the hinge frame 7 and the moving body, which drives the hinge frame 7 to rotate closer to the moving carrier 1, so that the driven wheel moves away from the driving wheel and tensions the cleaning track 2. The control structure includes a screw; a pressure portion is formed on the screw; a screw hole that mates with the screw is provided on the moving carrier 1; the pressure portion contacts the hinge frame 7.

[0058] The power supply guide rail utilizes a hinge-type disassembly principle. After the driven roller 32 is inserted into the rotating shaft 71, rotating the screw will cause the hinge frame 7 to move closer to the moving carrier 1. Simultaneously, the rotation of the hinge frame 7 will cause the driven roller 32 to move away from the driving roller 31, actively tensioning the cleaning track 2, facilitating installation. That is, the driven roller 32 can be installed when the cleaning track 2 is completely relaxed, and then the hinge frame 7 can be rotated closer to the moving carrier 1. Because the driven roller 32 is inserted into the insert shaft, as the insert shaft rotates with the hinge frame 7, the driven roller 32 does not move closer to the moving carrier 1, but slides relative to the insert shaft. This achieves convenient installation and disassembly of the driven roller 32. During installation, the cleaning track 2 can be in a relaxed state, allowing the driven roller 32 to gradually move away from the driving roller 31 for easier installation. During disassembly, the driven roller 32 can be removed first. As the driven roller 32 is removed, it moves towards the driving roller 31, also facilitating the disassembly of the cleaning track 2.

[0059] More specifically, the driven roller 32 is provided with a slot 321, into which the rotating shaft 71 is inserted. Multiple universal balls 72 are provided on the outer wall of the rotating shaft 71, contacting the inner wall of the slot 321. Utilizing the universal balls 72 on the rotating shaft 71, the driven roller 32 can move axially relative to the rotating shaft 71 and rotate on the rotating shaft 71 more easily. This greatly reduces the resistance to the movement of the driven roller 32 relative to the rotating shaft 71, resulting in less resistance during installation and facilitating installation and disassembly.

[0060] The working process of the power supply rail cleaning device is as follows:

[0061] Power supply guide rail 1, start-up and movement: The mobile carrier 1 (such as an RGV vehicle body) begins to move on the power supply guide rail. At the same time, the drive unit 3 starts, driving the drive roller 31 to rotate, which in turn drives the cleaning track 2 wrapped around the drive roller 31 and the driven roller 32 to start transmission. Crucially, the transmission direction of the cleaning track 2 is set to be opposite to the forward direction of the mobile carrier 1.

[0062] Power supply guide rail 2, contact and cleaning: During movement, the surface of the cleaning track 2 (or the cleaning brushes installed on it) maintains close contact with the surface of the power supply guide rail. Since the track drive direction is opposite to the carrier movement direction, a "reverse cleaning" effect is generated, effectively scraping off dust and impurities from the guide rail surface at a higher relative speed.

[0063] Power supply guide rail 3, air blowing assistance: While cleaning track 2 is in operation, the air blowing assembly 4 (such as a vortex fan 42) installed in its internal mounting area 22 is activated. Air is drawn in from the gaps on the side of the cleaning track 2, then pressurized and blown vertically or obliquely onto the surface of the power supply guide rail through the through-holes 21 on the track. This airflow blows up and disperses the light dust that has just been stripped and not carried away by the track, preventing it from settling again.

[0064] Power supply guide rail 4, waste collection and track self-cleaning: Most of the impurities that are cleaned and blown off fall into the receiving box 5 fixed below the mobile carrier 1 under the guidance of gravity and airflow. When the cleaning track 2 passes over the receiving box 5, the scraper teeth 6 set on the box body come into contact with the non-working surface of the track, scraping off the residual dirt adhering to the track and letting it fall into the receiving box 5, thereby completing the cleaning of the cleaning track 2 itself and ensuring the cleaning effect of its next cycle.

[0065] Power supply guide rail 5, maintenance process: When it is necessary to replace the cleaning track 2 or dump waste, first loosen the screw of the control structure, so that the articulated frame 7 rotates away from the moving carrier 1 under the action of gravity or external force. The driven roller 32 then moves closer to the driving roller 31, and the cleaning track 2 loosens. At this time, the driven roller 32 can be easily removed from the rotating shaft 71, and then the old cleaning track 2 can be removed. After installing the new track, reinstall the driven roller 32, tighten the screw, and push the articulated frame 7 to rotate through the pressure part, so that the driven roller 32 moves away from the driving roller 31, and the track can be re-tensioned. The receiving box 5 can also be disassembled and cleaned by releasing the magnetic attraction or unscrewing the bolts.

[0066] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
