[0023] This utility model provides an industrial RGV trolley system, which includes a track and an RGV trolley body that can move along the track. The RGV trolley body includes a first roller conveyor and a second roller conveyor, with several crossbeams arranged between the first roller conveyor and the second roller conveyor. The first roller conveyor and the second roller conveyor are perpendicular to the extension direction of the track. A drive wheel is provided at each end of the first roller conveyor, and a driven wheel is provided at each end of the second roller conveyor.

A detachable sheet metal base plate is provided on the crossbeam between the first roller conveyor and the second roller conveyor.

[0024] This utility model provides an industrial RGV (Remotely Reinforced Vehicle) trolley system. The roller conveyor and crossbeam base plate of the RGV trolley are covered with protective sheet metal, which is detachably installed outside the RGV trolley frame to prevent wear during long-term operation. Furthermore, the RGV trolley runs on a fixed track, suitable for transporting work boxes or sand boxes in factory workshops or 3D printing production lines. The track is fixed to the ground in advance according to the production line's transport requirements, allowing the RGV trolley to run along the predetermined track to transport work boxes or sand boxes.

[0025] The following description, in conjunction with specific embodiments, illustrates an industrial RGV (Remotely Targeted Vehicle) system to further illustrate the inventive concept of the industrial RGV system.

[0026] In one embodiment, such as Figure 2-3As shown, the industrial RGV trolley system includes a track 100 and an RGV trolley body 200 that can move along the track 100. The RGV trolley body 200 includes a first roller conveyor 210 and a second roller conveyor 220. A plurality of crossbeams 230 are arranged between the first roller conveyor 210 and the second roller conveyor 220, that is, the first roller conveyor 210 and the second roller conveyor 220 are fixedly connected into a whole by the crossbeams 230. The first roller conveyor 210 and the second roller conveyor 220 are perpendicular to the extension direction of the track 100. A drive wheel 211 is provided at both ends of the first roller conveyor 210, and a drive wheel 211 is provided at both ends of the second roller conveyor 220. A driven wheel 221 is provided. The driven wheel 211 and the driven wheel 221 cooperate with the track. The periphery of the driven wheel 211 and the driven wheel 221 are provided with a groove that cooperates with the upper end of the track 100. That is, the driven wheel 211 and the driven wheel 221 are engaged with the upper end surface of the track 100, so that the driven wheel 211 and the driven wheel 221 run along the track without derailing. The driven wheel 211 is equipped with a first drive motor 240. The first drive motor 240 is fixed on the outside of the first roller conveyor 210 and drives each of the driven wheels 211 to move on the track 100. When the RGV trolley needs to move, the first drive motor 240 is started, which drives the two drive wheels 211 on both sides to rotate, so that the drive wheels 211 move forward along the track. Under the drive of the drive wheels 211, the two driven wheels 221 on the second roller conveyor 220 also move forward along the track 100. The first roller conveyor 210 is covered by a detachable first protective shell 212, and the second roller conveyor 220 is covered by a detachable second protective shell 222. A detachable sheet metal base plate 231 is provided on the crossbeam 230 between the first roller conveyor 210 and the second roller conveyor 220. The first protective shell 213 and the second protective shell 222 are both protective sheet metal.

[0027] In this invention, the roller conveyor and crossbeam base plate of the RGV trolley are covered with protective sheet metal, which is detachably installed outside the frame of the RGV trolley. This prevents wear and tear during long-term operation and facilitates maintenance by removing the protective sheet metal in case of malfunction. Furthermore, the RGV trolley runs on a fixed track, making it suitable for transporting work boxes or sand boxes in factory workshops or 3D printing production lines. The track is pre-fixed to the ground according to the production line's transport requirements, allowing the RGV trolley to run along the predetermined track to transport work boxes or sand boxes.

[0028] In another embodiment, such as Figure 2As shown, the first drive motor 240 is equipped with a long drive shaft 241. One end of the long drive shaft 241 is connected to a drive wheel 211, and the other end of the long drive shaft 241 is connected to another drive wheel 211 through a bushing 242. That is, the first drive motor 240 drives the long drive shaft 241 to rotate, thereby driving the drive wheels 211 at both ends of the long drive shaft 241 to rotate.

[0029] In another embodiment, such as Figure 2 and 4 As shown, rollers 250 are respectively arranged on the inner sides of the first roller conveyor 210 and the second roller conveyor 220. Any two adjacent rollers 250 are connected by a chain 251. The rollers 250 extend outside the first protective shell 213 and the second protective shell 222. A second drive motor 260 is also arranged on the inner side of the second roller conveyor 220. The second drive motor 260 is connected to two rollers 250 on opposite sides by a long shaft 261. One end of the long shaft 261 is connected to two rollers 250 on both sides of the long shaft 261 on the first roller conveyor 210, and the other end of the long shaft 261 is connected to two rollers 250 on both sides of the long shaft on the second roller conveyor 210. Specifically, both ends of the long shaft are provided with sprockets, and the rollers 250 are also provided with double-row sprockets 252. The sprockets at the end of the long shaft 261 and the double-row sprockets 252 on the left and right rollers 250 are connected by a chain 251. When the second motor 260 drives the long shaft 261 to rotate, the long shaft 261 drives the rollers 250 on both sides to rotate. Since any two adjacent rollers 250 on each roller conveyor are connected by a chain 251 and double-row sprockets 252, the rotation of the rollers 250 on both sides of the long shaft 261 will drive all rollers 250 on each roller conveyor to rotate synchronously. In this embodiment, by setting rotatable rollers 250 on each roller conveyor, it is more convenient and less labor-intensive for the work box or sand box to enter and exit the RGV trolley.

[0030] In another embodiment, such as Figure 3 As shown, an electrical control cabinet 270 is also provided at one end of the second protective housing 222, through which the start and stop of the first drive motor 240 and the second drive motor 260 are controlled.

[0031] In another embodiment, the electrical control cabinet 270 is connected to the first drive motor 240 and the second drive motor 260 via sliding contact lines. The sliding contact lines can move with the RGV trolley, thereby supplying power to the RGV trolley.

[0032] In another embodiment, such as Figure 3As shown, the track 100 is pre-embedded in a pre-set foundation trench. When pre-embedding the track 100, the track 100 is leveled so that when the RGV trolley is running on the track, the upper surface of its rollers 250 is flush with the bottom surface of the work box or sand box, which facilitates moving the work box or sand box onto the RGV trolley.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
