Description

Technical Field

[0001] The present invention relates to the field of conveying technology in industrial automation, and in particular to a low-dust-generating adaptive power collector and a rail shuttle vehicle thereof. Background Art

[0002] The rail-based shuttle system, consisting of running tracks, shuttles, and a control system, provides energy supply, information transmission, memory storage, and logistics handling. Because the system requires the shuttles to operate on the tracks for extended periods, they require a continuous and stable energy supply. The rail-based shuttles draw power through rolling contact between their current collectors and the copper belts on the tracks, providing uninterrupted power to the shuttles.

[0003] The rail shuttle runs on the track and needs to be in close contact with the track to achieve the movement and guidance of the shuttle. In addition, when the power supply system is consistent with the direction of the track, it is necessary to ensure that the trolley collector is in close contact with the power supply conductor at all times to ensure the stability of the trolley's energy supply; otherwise, the trolley may cause a short circuit or power outage during operation, which may cause the line to paralyze and affect production efficiency. This requires that the trolley collector must ensure close contact with the power supply conductor, that is, the collector must have the requirement to adapt to the installation position of the power supply conductor. Secondly, the roller collector uses the conductive roller and its corresponding power supply copper belt to transfer current in close contact, that is, the conductive roller and its corresponding power supply copper belt are in sliding friction contact, which will inevitably cause greater wear and tear, and a large amount of debris will fall off, polluting the working environment. This makes it impossible for the shuttle to operate in a high-cleanliness environment, limiting its working environment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the conductive roller on the roller collector of the existing rail shuttle vehicle and its corresponding power supply copper belt are in sliding friction contact, resulting in large wear, causing a large amount of chip falling and other problems that pollute the working environment, making it impossible for the shuttle vehicle to operate in a high-cleanliness environment, and limiting its working environment, a low-dust adaptive power collector and its rail shuttle vehicle are now provided.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a low-dust-generating adaptive power collector, comprising an insulating support and at least one set of conductive mechanisms disposed on the insulating support, wherein the conductive mechanisms include two conductive rollers rotatably disposed on the insulating support, one of the conductive rollers being in rolling contact with a positive power supply copper belt, and the other conductive roller being in rolling contact with a negative power supply copper belt;

[0006] Each of the two conductive rollers includes a central shaft and a roller body, the roller body being rotatably mounted on the central shaft. A sealed cavity is defined between the roller body and the central shaft, and a conductive medium is disposed within the sealed cavity for conducting electricity between the roller body and the central shaft. Compared to the prior art, this solution replaces the original sliding frictional contact between the conductive roller and its corresponding power supply copper belt with rolling contact between the conductive roller and the power supply copper belt. This significantly reduces wear on the conductive roller and its corresponding power supply copper belt, preventing dust drop and other contamination of the working environment. Furthermore, locations within the conductive roller that are prone to dust generation are located within the sealed cavity, resolving the issue of dust drop and contamination of the work environment caused by friction within the conductive roller. This allows the rail shuttle to operate in a highly clean environment, improving its suitability for working environments.

[0007] In order to realize a sealed cavity between the roller body and the central shaft, some preferred embodiments are that the roller body and the central shaft are rotatably mounted with bearings, there are two bearings and they are relatively mounted at both ends of the roller body, two sealing rings are arranged on the central shaft between the two bearings, and a sealed cavity is formed between the inner ring wall of the roller body, the sealing ring on one side, the central shaft and the sealing ring on the other side.

[0008] In order to realize the conductive medium, in some preferred embodiments, the conductive medium is a fluid conductive material.

[0009] In order to realize the conductive medium, in some preferred embodiments, the conductive medium is a brush copper sheet, one end of the brush copper sheet is fixed on the central axis, and the other end of the brush copper sheet abuts against the inner ring wall of the roller body.

[0010] In order to ensure the brush copper strip, some preferred embodiments are that the brush copper strip includes a fixed section and a contact section connected in sequence, the fixed section is fixedly installed on the central axis, the contact section is gradually bent into an arc along its rotation direction, the arc of the contact section matches the inner ring wall of the roller body, and the arc of the contact section is against the inner ring wall of the roller body.

[0011] In some preferred embodiments, a bracket is provided between each of the conductive rollers and the insulating support, the central axis of each of the conductive rollers is fixed to one end of the bracket, and the insulating support is rotatably mounted on the other end of the bracket.

[0012] In some preferred embodiments, a rebound device is provided between the bracket and the insulating support, configured to maintain close contact between the conductive roller and the power supply copper strip. The rebound device preloads the conductive roller in an adaptive manner, maintaining close contact between the current collector and the power supply copper strip at all times, preventing short circuits and maintaining a stable energy supply during operation of the shuttle.

[0013] In some preferred embodiments, the rebound device is a spring.

[0014] In some preferred embodiments, there are two groups of conductive mechanisms.

[0015] A rail shuttle vehicle is equipped with the low-dust-generating adaptive power collector as described above.

[0016] The beneficial effects of the present invention are as follows: when a low-dust adaptive power collector and its rail shuttle vehicle are in use, the sliding friction contact between the original conductive roller and the corresponding power supply copper belt is changed to rolling contact between the conductive roller and the power supply copper belt, thereby greatly reducing the wear of the conductive roller and the power supply copper belt and preventing the phenomenon of chip falling and other pollution to the working environment. At the same time, the position where dust is easily generated in the conductive roller is set in a closed cavity, which solves the problem of chip falling due to friction inside the conductive roller and pollution of the work environment, allowing the rail shuttle vehicle to operate in a high-cleanliness environment, improving the applicability of the rail shuttle vehicle to the working environment, and avoiding the sliding friction contact between the conductive roller and the corresponding power supply copper belt on the roller collector of the existing rail shuttle vehicle, resulting in greater wear, leading to a large amount of chip falling and other pollution to the working environment, making it impossible for the shuttle vehicle to operate in a high-cleanliness environment, limiting its working environment problem.

[0032] Example 1

[0033] like Figure 1-7As shown, a low-dust-generating adaptive power collector includes an insulating support 1. In this embodiment, two sets of conductive mechanisms are installed on the insulating support 1. Of course, in addition to two sets, the conductive mechanisms can also be three, four, or more sets, which are installed according to usage needs. The conductive mechanisms include two conductive rollers 2 rotatably arranged on the insulating support 1, and the positive power supply copper belt 3 and the negative power supply copper belt 4 are parallel to each other and spaced apart and arranged on the same side. One conductive roller 2 in each set of conductive mechanisms is in rolling contact with the positive power supply copper belt 3, and the other conductive roller 2 in each set of conductive mechanisms is in rolling contact with the negative power supply copper belt 4.

[0034] The two conductive rollers 2 in each set of conductive mechanisms include a central shaft 5 and a roller body 6. The roller body 6 and the central shaft 5 are rotatably mounted with each other via bearings 13. There are two bearings 13 that are relatively mounted at both ends of the roller body 6. Two sealing rings 14 are provided on the central shaft 5 between the two bearings 13. A sealed cavity 7 is formed between the inner ring wall of the roller body 6, the sealing ring 14 on one side, the central shaft 5 and the sealing ring 14 on the other side, so that a sealed cavity 7 is provided between the roller body 6 and the central shaft 5. A conductive medium for conducting electricity between the roller body 6 and the central shaft 5 is provided in the sealed cavity 7.

[0035] The conductive medium is a fluid conductive material 8. In this embodiment, the fluid conductive material 8 is liquid metal mercury, or a gallium-based alloy such as gallium indium tin alloy, which is liquid at room temperature and has a conductivity close to that of metal (~10 6 S / m), non-toxic, can achieve a stable non-contact conductive method by pouring 3 / 4 of the volume of the sealed cavity 7 into the interior, and the sealing gaskets at both ends make the interior achieve a more reliable sealing environment.

[0036] A bracket 12 is provided between each conductive roller 2 and the insulating support. The central axis 5 on each conductive roller 2 is fixed to one end of the bracket 12, and the insulating support is rotatably installed at the other end of the bracket 12. A rebound device is provided between the bracket 12 and the insulating support. The rebound device is used to make the conductive roller 2 in close contact with the power supply copper belt. In this embodiment, the rebound device is a cylindrical coil spring. Of course, in addition to the cylindrical coil spring, the rebound device can also be a gas spring to achieve close contact between the conductive roller 2 of the adaptive dust-free collector and its corresponding power supply copper belt. The bracket 12 is rotatably connected to the insulating support 1, and under the action of the rebound device, the conductive roller 2 moves up and down relative to the copper belt plane, and the conductive roller 2 can adapt to the deformation of the copper belt.

[0037] Example 2

[0038] The difference between Example 2 and Example 1 lies in the difference in the conductive medium in the sealed cavity 7, specifically: Figure 8-9As shown, the conductive medium is a brush copper sheet 9, one end of the brush copper sheet 9 is fixed on the central shaft 5, and the other end of the brush copper sheet 9 is in contact with the inner ring wall of the roller body 6. There are two brush copper sheets 9 and they are arranged symmetrically around the center. The brush copper sheet 9 has resilience and can be tightly attached to the inner ring of the roller body 6 and connect the central shaft 5 and the conductive roller 2 to achieve stable conduction.

[0039] The brush copper strip includes a fixed section 10 and a contact section 11 connected in sequence. The fixed section 10 is fixedly installed on the central shaft 5. The contact section 11 is gradually curved along its rotation direction. The arc of the contact section 11 matches the inner ring wall of the roller body 6. The arc of the contact section 11 is against the inner ring wall of the roller body 6.

[0040] Example 3

[0041] Example 3 is an implementation of Examples 1 and 2, specifically: a rail shuttle vehicle equipped with a low-dust-generating adaptive power collector as described above.

[0042] When the above-mentioned low-dust adaptive power collector and its rail shuttle are in use, the conductive medium is built-in, that is, the conductive medium is enclosed in the sealed cavity 7 of the conductive roller 2, so that the location where dust is easily generated is located in the sealed cavity 7, that is, the rolling friction between the conductive roller 2 of the external collector and the corresponding power supply copper belt, which greatly reduces the friction between the two. The built-in conductive medium and the rolling friction between the conductive roller 2 and the corresponding power supply copper belt solve the problem of large-scale powder loss and broaden the use environment of the shuttle.

[0043] The above description of the preferred embodiments of the present invention is intended to serve as a guide. Based on the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
