[0002] The intelligent RGV vehicle refers to an automatic guided vehicle (RGV) with intelligent functions, which is often used in automated production lines or warehousing systems to transport materials or goods.

[0003] In the prior art, when the intelligent RGV trolley is running on the track, in order to ensure that the intelligent RGV trolley and the track remain stable, a limiting wheel is installed on the side of the trolley's driving wheel to ensure that the intelligent RGV trolley runs stably on the upper part of the track and avoid the intelligent RGV trolley from derailing during driving. The limiting wheel will be worn during use, resulting in a gradual increase in the gap between the limiting wheel and the track, causing the limiting effect of the limiting wheel to be weakened, which is not conducive to the stable driving of the intelligent RGV trolley. Summary of the invention

[0004] In order to solve the problem that the gap between the limiting wheel and the track gradually increases after the limiting wheel is worn during use, causing the limiting effect of the limiting wheel to weaken, which is not conducive to the stable driving of the intelligent RGV vehicle, the utility model provides an intelligent RGV vehicle to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An intelligent RGV trolley, comprising an RGV trolley mechanism, wherein the RGV trolley mechanism is fixedly connected to a limiting mechanism on the side, the RGV trolley mechanism comprises an intelligent RGV trolley body, an active wheel is installed at the bottom of the intelligent RGV trolley body, and the limiting mechanism comprises a fixing frame and a mounting plate, the fixing frame is fixedly connected to the side of the intelligent RGV trolley body, and a guide rail is fixedly connected to the bottom of the fixing frame, a slider is slidably connected to the inside of the guide rail, a telescopic rod is fixedly connected to the inside of the guide rail, one end of the telescopic rod is fixedly connected to the side of the slider, and a spring is arranged on the surface of the telescopic rod, one end of the spring is fixedly connected to the guide rail, and the other end of the spring is fixedly connected to the slider, a fixing block is fixedly connected to the bottom of the slider, a plug block is fixedly connected to the bottom of the fixing block, the mounting plate is plugged with the plug block, and a fixing plate is fixedly connected to the bottom of the mounting plate, a connector is fixedly connected to the side of the fixing plate, a connecting shaft is rotatably connected to the bottom of the connecting head, and a limiting wheel is fixedly connected to the bottom of the connecting shaft.

[0007] Furthermore, two guide rods are fixedly connected inside the guide rail, and the two guide rods are symmetrically distributed on both sides of the telescopic rod.

[0008] Furthermore, the sliding block is slidably plugged into the guide rod.

[0009] Furthermore, a slot is provided on the surface of the mounting plate, and the plug-in block is located inside the slot and plugged into the mounting plate.

[0010] Furthermore, a mounting bolt is inserted into the surface of the mounting plate, the mounting bolt is inserted into the plug block, and one end of the mounting bolt is threadedly connected with a fixing nut, and the fixing nut is fitted with the side surface of the mounting plate.

[0011] Furthermore, the driving wheel is in contact with the upper part of the track, and the limiting wheel is in contact with the side of the track.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, during long-term use, when the limiting wheel is worn by the side of the track, the telescopic rod and the spring will push the slider to slide along the guide rail. At this time, the slider drives the fixed block, the plug block and the mounting plate to move to the side close to the track. The mounting plate will push the connecting head and the connecting shaft to make the limiting wheel always fit the side of the track. The elastic force of the spring makes the limiting wheel limit the side of the RGV trolley mechanism, thereby improving the stability of the RGV trolley mechanism during movement.

[0014] 2.

A spring 213 is provided on the surface of the rod 212, one end of the spring 213 is fixedly connected to the guide rail 22, and the other end of the spring 213 is fixedly connected to the slider 23, the bottom of the slider 23 is fixedly connected to a fixed block 24, the bottom of the fixed block 24 is fixedly connected to an insertion block 25, the mounting plate 26 is plugged with the insertion block 25, and the bottom of the mounting plate 26 is fixedly connected to a fixed plate 28, the side of the fixed plate 28 is fixedly connected to a connector 29, the bottom of the connector 29 is rotatably connected to a connecting shaft 210, the bottom of the connecting shaft 210 is fixedly connected to a limited wheel 211, the active wheel 12 is in contact with the upper part of the track 3, and the limited wheel 211 is in contact with the side of the track 3.

[0023] Specifically, when the RGV trolley mechanism 1 is moving, the active wheel 12 rolls on the upper part of the track 3, and the limiting wheel 211 rolls along the side of the track 3. The limiting wheel 211 limits the side of the RGV trolley mechanism 1, thereby improving the stability of the RGV trolley mechanism 1 when moving on the surface of the track 3. During long-term use, when the limiting wheel 211 is worn by the side of the track 3, the telescopic rod 212 and the spring 213 will push the slider 23 to slide along the guide rail 22. At this time, the slider 23 drives the fixing block 24, the plug block 25 and the mounting plate 26 to move toward the side close to the track 3. The mounting plate 26 will push the connecting head 29 and the connecting shaft 210, so that the limiting wheel 211 is always in contact with the side of the track 3. The elastic force of the spring 213 is used to limit the side of the RGV trolley mechanism 1, thereby improving the stability of the RGV trolley mechanism 1 during movement.

[0024] As an optimization solution, Figure 3 and Figure 4 As shown, two guide rods 214 are fixedly connected inside the guide rail 22, and the two guide rods 214 are symmetrically distributed on both sides of the telescopic rod 212. The slider 23 is slidably plugged into the guide rods 214, and a slot 27 is provided on the surface of the mounting plate 26. The plug block 25 is located inside the slot 27 and plugged into the mounting plate 26. A mounting bolt 215 is plugged into the surface of the mounting plate 26, and the mounting bolt 215 is plugged into the plug block 25. A fixing nut 216 is threadedly connected to one end of the mounting bolt 215, and the fixing nut 216 is fitted with the side of the mounting plate 26.

[0025] Specifically, when the limiting wheel 211 is severely worn, the elastic force of the spring 213 to restore the deformation will be insufficient to limit the side of the RGV trolley mechanism 1. At this time, unscrew the fixing nut 216, pull out the mounting bolt 215 from the mounting plate 26 and the plug block 25, and then pull out the plug block 25 from the inside of the mounting plate 26 to facilitate replacement of a new limiting wheel 211. When the slider 23 slides along the guide rail 22, the slider 23 will slide along the guide rod 214, and the slider 23 will be limited by the guide rod 214, thereby improving the stability of the slider 23 when sliding.

[0026] Working principle: When the RGV trolley mechanism 1 is moving, the active wheel 12 rolls on the upper part of the track 3, and the limiting wheel 211 rolls along the side of the track 3. The limiting wheel 211 limits the side of the RGV trolley mechanism 1, thereby improving the stability of the RGV trolley mechanism 1 when moving on the surface of the track 3. During long-term use, when the limiting wheel 211 is worn by the side of the track 3, the telescopic rod 212 and the spring 213 will push the slider 23 to slide along the guide rail 22. At this time, the slider 23 drives the fixing block 24, the insert block 25 and the mounting plate 26 to move to the side close to the track 3. The mounting plate 26 will push the connector 29 and the connecting shaft 210, so that the limiting wheel 211 is always attached to the side of the track 3, and the limiting wheel 211 limits the side of the RGV trolley mechanism 1 through the elastic force of the spring 213.

[0027] When the limiting wheel 211 is severely worn, the elastic force of the spring 213 to restore its deformation will be insufficient to limit the side of the RGV trolley mechanism 1. At this time, unscrew the fixing nut 216, pull out the mounting bolt 215 from the mounting plate 26 and the plug block 25, and then pull out the plug block 25 from the mounting plate 26, replace the new limiting wheel 211, and when the slider 23 slides along the guide rail 22, the slider 23 will slide along the guide rod 214, and the slider 23 will be limited by the guide rod 214.
