Description

Technical Field

[0001] The 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 shuttle transportation system consists of running tracks, shuttles, control systems and other parts. It is a transportation system with functions such as energy supply, information transmission, memory storage, and logistics handling. Because the transportation system requires the shuttle to run on the track for a long time, the shuttle needs a continuous and stable energy supply method. The rail shuttle draws electricity through its own collector and rolling contact with the power supply copper belt on the track, thereby achieving uninterrupted power supply for the shuttle.

[0003] The rail shuttle runs on the track, and it 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 be short-circuited or power off during operation, resulting in line paralysis and affecting 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 of adaptive power supply conductor installation position. Secondly, the roller collector uses the conductive roller to closely contact with its corresponding power supply copper belt for current transmission, 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, which causes great wear and leads to 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, thus limiting its working environment, a low-dust-generating adaptive power collector and a rail shuttle vehicle thereof 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 group of conductive mechanisms arranged on the insulating support, wherein the conductive mechanisms include two conductive rollers rotatably arranged on the insulating support, one of the conductive rollers is in rolling contact with a positive power supply copper belt, and the other conductive roller is in rolling contact with a negative power supply copper belt;

Compared with the prior art, this solution changes the sliding friction contact between the original conductive roller and the corresponding power supply copper belt to rolling contact between the conductive roller and the power supply copper belt, thereby greatly reducing the wear of the conductive roller and the corresponding power supply copper belt, and preventing the phenomenon of pollution of the working environment such as chip falling. At the same time, the position where dust is easily generated in the conductive roller is set in a closed cavity, so as to solve the problem of chip falling and pollution of the tooling environment caused by friction inside the conductive roller, so that the rail shuttle can operate in a high-cleanliness environment, and improve the applicability of the rail shuttle to the working environment.

[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 is in contact with 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 in 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, a central axis on 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, and the rebound device is used to make the conductive roller in close contact with the power supply copper belt. The rebound device makes the conductive roller pre-pressed in an adaptive manner, always keeps the collector in close contact with the power supply copper belt, prevents virtual connection and short circuit, and maintains stable energy supply when the shuttle is running.

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

[0014] In some preferred embodiments, the conductive mechanism has two groups.

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

[0016] The beneficial effects of the present invention are as follows: when the low-dust-generating adaptive power collector and the rail shuttle vehicle thereof 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 dropping and other pollution to the working environment.

[0032] Example 1

[0033] like Figure 1-7As shown, a low dust-generating adaptive power collector comprises an insulating support 1. In this embodiment, two groups of conductive mechanisms are installed on the insulating support 1. Of course, the conductive mechanisms may be three, four or more groups in addition to two groups, and are installed according to the needs of use. 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 on the same side, wherein one conductive roller 2 in each group of conductive mechanisms is in rolling contact with the positive power supply copper belt 3, and another conductive roller 2 in each group 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 axis 5 and a roller body 6. The roller body 6 and the central axis 5 are rotatably mounted with bearings 13. There are two bearings 13 that are relatively mounted at both ends of the roller body 6. Two sealing rings 14 are arranged on the central axis 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 axis 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 axis 5. A conductive medium for conducting electricity between the roller body 6 and the central axis 5 is arranged 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 realize stable non-contact conductive mode by pouring 3 / 4 of the volume of the sealed cavity 7 inside, and the sealing gaskets at both ends make the inside realize a more reliable sealing environment.

[0036] A bracket 12 is arranged between each conductive roller 2 and the insulating support, the central axis 5 on each conductive roller 2 is fixed at 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 arranged between the bracket 12 and the insulating support, and 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, the rebound device can be a gas spring in addition to the cylindrical coil spring, so as 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 floats, so that 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 centrally symmetrically arranged. 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 bent in an arc shape along its rotation direction. The arc shape of the contact section 11 matches the inner ring wall of the roller body 6. The arc shape 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 position 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 amounts of dust falling and broaden the use environment of the shuttle.

[0043] The above-mentioned ideal embodiments of the present invention are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the technical idea of ​​the present invention. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
