Description

Technical Field

[0002] With the advancement, development and popularization of logistics automation technology, the industry scope of material transportation has also expanded. The demand for transporting oversized and heavy-loaded materials (greater than 3 meters in size and weighing more than 3 tons) in industries such as photovoltaics, chemical fibers, and new materials is increasing. The track change devices currently proposed are only for the transportation of conventional standard small and medium-sized conventional pallet materials. When transporting oversized and heavy-loaded pallet materials, the size and weight of the heavy-load shuttle equipment for conveying the materials will be greatly doubled. Traditional track change devices can no longer be achieved by simply scaling up and applying them.

[0003] In particular, when the track change device is subjected to large lateral forces during the operation of a heavily loaded shuttle, it is prone to swinging. Existing proposed track change device positioning methods are complex, time-consuming, and unreliable. This makes it difficult to ensure the stability of the track change device during operation, which can easily lead to track docking failure. Utility Model Content

[0011] A plurality of supporting roller mounting slots are provided inside the rotating disk. Support rollers A are mounted on the inner side surfaces of the supporting roller mounting slots of the rotating disk. Each supporting roller A is rotatably mounted on the inner disc.

[0012] The outer circumference of the rotating disk is divided into a continuously connected notch edge portion and a superior arc edge portion, and the magnetic stand A and the magnetic stand B are respectively installed at two ends of the notch edge portion of the outer circumference of the rotating disk.

[0013] A plurality of supporting rollers B are evenly arranged on the arc-shaped edge portion of the outer peripheral surface of the rotating disk, and each of the supporting rollers B is respectively rolled on the outer ring track.

[0014] A gap A is formed between the edge of the gap on the outer circumference of the rotating disk and the outer ring track, and the driving motor, magnetic fixing component A and magnetic fixing component B are respectively arranged on the ground corresponding to the gap A.

[0015] The driving shaft of the driving motor is vertically downward and is provided with a driving gear. The rotating disk is provided with an arc-shaped rack, which is meshed with the driving gear.

[0030] The following is combined with Figure 1-7 The utility model is further described in detail.

[0031] A heavy-load magnetic rotary track changing device is suitable for changing the connection between the preceding straight track 001 and the following straight track 002 or the following curved track 003 to allow the shuttle to pass. Figure 1-7 As shown, this embodiment includes a drive motor 1, a fixed chassis 2, a rotating disk 3, a rotating disk straight rail 4, a rotating disk curved rail 5, a co-arranged magnetic vertical plate A 6 and a magnetic fixing component A, and a co-arranged magnetic vertical plate B 7 and a magnetic fixing component B.

[0032] The fixed chassis 2, magnetic fixing component A, and magnetic fixing component B are respectively installed on the ground. The middle part of the bottom surface of the rotating disk 3 is rotatably connected to the middle part of the fixed chassis 2 through a slewing bearing 8. The rotating disk straight rail 4 and the rotating disk curved rail 5 are respectively installed on the top surface of the rotating disk 3. The magnetic vertical plate A 6 and the magnetic vertical plate B 7 are respectively installed on the rotating disk 3. The drive motor 1 is used to drive the rotating disk 3 to rotate.

[0033] The rotating disk straight rail 4 is used to dock with the preceding straight rail 001 and the following straight rail 002, respectively, and the rotating disk curved rail 5 is used to dock with the preceding straight rail 001 and the following curved rail 003, respectively. When the rotating disk straight rail 4 is docked with the preceding straight rail 001 and the following straight rail 002, respectively, the rotating disk curved rail 5 is offset from the preceding straight rail 001 and the following curved rail 003, respectively. At this time, the magnetic vertical plate A 6 is attracted to the co-provided magnetic fixing assembly A, and the magnetic vertical plate B 7 is separated from the co-provided magnetic fixing assembly B. When the rotating disk curved rail 5 is docked with the preceding straight rail 001 and the following curved rail 003, respectively, the rotating disk straight rail 4 is offset from the preceding straight rail 001 and the following straight rail 002, respectively. At this time, the magnetic vertical plate B 7 is attracted to the co-provided magnetic fixing assembly B, and the magnetic vertical plate A 6 is separated from the co-provided magnetic fixing assembly A.

[0034] Specifically, if Figure 3 As shown, in this embodiment, the fixed chassis 2 is divided into an inner disc 201 and an outer track 202. The inner disc 201 is located inside the outer track 202. The inner disc 201 and the outer track 202 are concentrically mounted on the ground, with the slewing bearing 8 positioned in the center of the inner disc 201. The installation method for the inner disc 201 and the outer track 202 on the ground uses existing technology, requiring careful attention to ensuring levelness. This separate configuration also facilitates independent disassembly, reducing the amount of machining required for large-scale chassis, saving processing and transportation costs, and is more economical. The slewing bearing 8 is a commercially available product and is mounted using existing technology. The inner disc 201 and the outer track 202 are connected by six circumferentially arranged cross braces 203. These cross braces 203 are bolted to the inner disc 201 and the outer track 202, respectively, to enhance overall strength. In this embodiment, the outer ring track 202 is in a circular shape as a whole.

[0035] Specifically, if Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment, the rotating disk 3 has two support roller mounting slots 301 defined within it. A support roller A9 is mounted on the inner side of each support roller mounting slot 301 of the rotating disk 3. Each support roller A9 rolls on the inner disk 201. When the rotating disk 3 rotates, each support roller A9 rolls on the inner disk 201, effectively adapting to heavy-load conditions of the rotating disk 3, ensuring that the rotating disk 3 is subjected to stable force and capable of withstanding greater loads.

[0036] like Figure 1 、 Figure 2 and Figure 6As shown, in this embodiment, the outer circumference of the rotating disk 3 is divided into a continuously connected notched edge portion and a superior arc-shaped edge portion. Magnetic risers A6 and B7 are respectively mounted on opposite ends of the notched edge portion of the outer circumference of the rotating disk 3. Several support rollers B10 are evenly arranged along the superior arc-shaped edge portion of the outer circumference of the rotating disk 3. Each support roller B10 rolls on the outer ring track 202. As the rotating disk 3 rotates, each support roller B10 rolls on the outer ring track 202, effectively adapting to heavy-load conditions of the rotating disk 3, ensuring that the rotating disk 3 is subjected to stable force and can withstand greater loads.

[0037] like Figure 1 、 Figure 2 As shown, in this embodiment, a gap A004 is formed between the edge of the notch on the outer circumference of the rotating disk 3 and the outer ring track 202. The drive motor 1, magnetic fixing assembly A, and magnetic fixing assembly B are respectively arranged on the ground corresponding to the notch A004, facilitating the installation of the drive motor 1, magnetic fixing assembly A, and magnetic fixing assembly B, making the overall structure compact. The drive shaft of the drive motor 1 is vertically downward and is equipped with a drive gear 11. The rotating disk 3 is equipped with an arcuate rack 12, which meshes with the drive gear 11. The center of the circle corresponding to the arcuate rack 12 is collinear with the center of the fixed chassis 2 and the center of the rotating disk 3. In this embodiment, the drive motor 1 is a commercially available product. The drive motor 1 is mounted on the ground using a conventional motor mounting bracket structure. The drive motor 1 is controlled by an external controller. The drive motor 1 drives the rotating disk 3 equipped with the arcuate rack 12 via the drive gear 11, thereby achieving control of the rotation and track change. By adopting a transmission method using an arcuate rack 12 and a drive gear 11, unlike the traditional drive component driving the slewing support bearing, higher transmission accuracy can be achieved when rotating a large-diameter rotating disk 3. In addition, the number of transmission poles can be reduced, reducing transmission efficiency losses. During maintenance and overhaul, it is necessary to level a portion of the outer ring track 202 installed on the ground. Since the outer ring track 202 is generally annular, the rotating disk 3 can rotate on the outer ring track 202 at any large angle, and the notch A 004 can be aligned with the corresponding outer ring track 202 position requiring adjustment. This eliminates the need to remove the entire rotating disk 3 from the fixed chassis 2, facilitating the installation and adjustment of the outer ring track 202.

[0038] Specifically, if Figure 1 、 Figure 6 and Figure 7As shown, the structures of the magnetic fixing assembly A and magnetic fixing assembly B in this embodiment are essentially the same, both comprising a magnetic fixing assembly base 13, an electromagnet 14, and a micro-sensor switch 15. The magnetic fixing assembly base 13 is mounted on the ground, the electromagnet 14 is mounted on the magnetic fixing assembly base 13, and the micro-sensor switch 15 is mounted on the magnetic fixing assembly base 13 via a switch bracket 16. In this embodiment, the electromagnet 14 and the micro-sensor switch 15 are both commercially available products and are each connected to an external controller. The magnetic stand A 6 and magnetic stand B 7 are both made of a magnetically attractive material, such as stainless steel. The mounting method between the magnetic stand A 6 and magnetic stand B 7 and the rotating disk 3 also utilizes conventional techniques, such as screw connections. The specific placement of the magnetic fixing assembly A, magnetic fixing assembly B, magnetic stand A 6, and magnetic stand B 7 can be adjusted as needed based on the operating conditions. The micro-sensor switch 15 is used to detect whether the corresponding rotating disk straight track 4 or rotating disk curved track 5 is close to the electromagnet 14. When the micro-sensor switch 15 detects that the corresponding rotating disk straight track 4 or rotating disk curved track 5 is close enough to the electromagnet 14, it sends a signal to the external controller, which then controls the electromagnet 14 to energize and attract the corresponding magnetic stand A 6 or magnetic stand B 7. When the micro-sensor switch 15 detects that the corresponding rotating disk straight track 4 or rotating disk curved track 5 is away from the electromagnet 14, it sends a signal to the external controller, ensuring that the external controller controls the electromagnet 14 to deenergize.

[0039] By coordinating the magnetic vertical plate A 6 and the magnetic fixing assembly A, as well as the magnetic vertical plate B 7 and the magnetic fixing assembly B, the bidirectional rotation and swing of the rotating disk 3 around its axis can be effectively limited by the magnetic force after the track change, ensuring the positional relationship between the docking track (rotating disk straight track 4 and rotating disk curved track 5) on the rotating disk 3 and the main line track (first straight track 001, second straight track 002, and second curved track 003). Especially when the shuttle transports heavy-loaded materials around a bend, the rotating disk 3 will be subjected to a large lateral force. The bidirectional limit of magnetic attraction can ensure that the rotating disk 3 does not rotate due to external forces, ensuring the stability of the track change device. The safety of the shuttle passing through can be further guaranteed by setting a micro-sensor switch 15. The electromagnet 14 can absorb electricity in a short time, and the entire magnetic attraction action is executed very quickly with high stability and economy.

[0040] In this embodiment, the front side of the electromagnet 14 is used to directly engage with the corresponding magnetic stand A 6 or magnetic stand B 7. One end of four adjustment screws 17 are evenly fixed to the rear side of the electromagnet 14 in a rectangular array. The magnetic fixing assembly base 13 defines adjustment screw holes for the other ends of the adjustment screws 17 on the corresponding electromagnet 14. Adjustment nuts 18 are threadedly mounted on each adjustment screw 17, located on the front and rear sides of the corresponding magnetic fixing assembly base 13. By passing the four adjustment screws 17 on the rear side of the electromagnet 14 through the magnetic fixing assembly base 13, the orientation angle of the front side of the electromagnet 14 can be slightly adjusted to ensure that the front side of the electromagnet 14 engages with the corresponding magnetic stand A 6 or magnetic stand B 7 without affecting the horizontality of the rotating disk 3 and ensuring accurate docking. After tightening the adjustment nuts 18 on the adjustment screws 17, the position and angle of the electromagnet 1 remain fixed.
