Description

Technical Field

[0001] The invention relates to the technical field of rail vehicles, and in particular to an RGV anti-dumping roller device. Background Art

[0002] RGV is an automated transport equipment, usually composed of a body, axles, drive system and control system. It can automatically travel on a predetermined track, carrying and moving goods. However, during high-speed transportation and turning, RGV is prone to rollover, which may cause damage to goods, equipment damage and work safety issues.

[0003] For example, the publication number "CN117141969A" discloses "an RGV trolley turntable structure", which includes a guide rail assembly, a trolley body that can move forward and backward on the guide rail assembly, a turntable that can rotate horizontally is provided on the trolley body, and a material transport mechanism that can linearly transport materials horizontally is provided on the turntable. However, in actual applications, during high-speed transportation and turning, RGV is prone to rollover, which may cause damage to goods, equipment and work safety issues. Summary of the invention

[0004] In view of the problem of rollover risk of RGV in the prior art mentioned in the background technology, the present invention provides an RGV anti-tipping roller device, which can prevent rollover during high-speed transportation and turning, thereby ensuring the stability of the RGV during operation, protecting the safety of the goods, and maintaining the normal operation of the entire system.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] An RGV anti-dumping roller device includes a rail vehicle body, the rail vehicle body is slidably connected to the track, the rail vehicle body is connected to a lateral mounting seat, the lateral mounting seat is connected to a side roller group, the track includes a lower rail surface, and the side roller group includes an anti-dumping roller abutting against the lower rail surface. In the present application, by arranging a lateral mounting seat on the rail vehicle body, an anti-dumping roller is connected to the lateral mounting seat, and the anti-dumping roller abuts against the lower rail surface, when the vehicle has a tendency to roll over, the contact between the anti-dumping roller and the lower rail surface can fix the vehicle on the track to avoid rollover, thereby ensuring the safety of the vehicle.

[0007] Preferably, the lateral mounting seat includes an angled mounting plate, the angled mounting plate includes a positioning plate and a connecting plate, the positioning plate is connected to the rail vehicle body, and the connecting plate is connected to the side roller assembly. By providing the angled mounting plate, the inclination angle of the rail vehicle body and the lower rail surface can be adapted to the change. When the RGV is installed on different rails, it can be adapted by replacing different angled mounting plates, thereby improving the flexibility and adaptability of the RGV.

[0008] Preferably, the lower rail surface is inclined, the connecting plate is inclined relative to the positioning plate, the inclination angle of the connecting plate corresponds to the inclination angle of the lower rail surface, and the anti-dumping roller fits the lower rail surface. The inclination angle of the positioning plate is set corresponding to the inclination angle of the lower rail surface, so as to ensure that the anti-dumping roller can fit well with the lower rail surface, thereby improving the stability of the vehicle, and can obtain a certain guiding ability through the anti-dumping roller, thereby improving the stability of operation.

[0009] Preferably, the lateral mounting seat includes a shaft mounting plate connected to the connecting plate, and the connecting plate is provided with a mounting groove. The lateral mounting seat includes a shaft mounting seat connected to the connecting plate, wherein the shaft mounting seat is used to fix the connecting shaft, wherein the connecting plate is provided with a mounting groove, which can avoid the connection and installation of the connecting shaft and the shaft mounting seat, and facilitate installation.

[0010] Preferably, the anti-dump roller includes an inner ring wheel and an outer ring wheel, an elastic block is connected between the inner ring wheel and the outer ring wheel, the outer ring wheel abuts the lower rail surface, and the side roller group includes a connecting shaft, and the inner ring wheel is connected to the connecting shaft. The anti-dump roller includes an inner ring wheel and an outer ring wheel, wherein the inner ring wheel is arranged inside the outer ring wheel, and the inner ring wheel and the outer ring wheel are connected by an elastic block, wherein the elastic block can play a shock-absorbing effect, and in the case of high-speed turning, when the centrifugal force is large, it can cause a certain deformation, and tilt the entire RGV vehicle to a certain angle. Since it always maintains contact with the lower rail surface, the anti-dump roller will not be separated from the lower rail surface, and the anti-dump effect can continue to be guaranteed. Due to the deformability of the elastic block, when it is slightly squeezed and deformed, the anti-dump roller can maintain relative rolling, and when the compression of the elastic block reaches a large amount, it will cause the eccentricity between the inner ring wheel and the outer ring wheel to be large, and the anti-dump roller will not be detached from the lower rail surface. The wheels are not easy to roll, and the rolling friction between them and the lower rail surface is transformed into sliding friction, which increases the friction force and adaptively reduces the vehicle speed. Preferably, when the traction device of the RGV detects an increase in resistance, it will adaptively reduce the vehicle speed to avoid further increasing the rollover tendency and protect the safety of the vehicle. Since the anti-dump roller is connected to the lower rail surface of the track, the anti-dump roller will not be squeezed during normal working. Only when there is a tendency to tip over, as the tipping force gradually increases, the elastic block is continuously squeezed, resulting in a gradual increase in the eccentricity between the inner ring wheel and the outer ring wheel, thereby causing the anti-tipping roller to be unable to rotate normally, the friction force becomes larger, the vehicle speed is reduced, and feedback is given to the traction device to reduce the vehicle speed.

[0011] Preferably, there are several outer ring wheels, and installation gaps are left between adjacent outer ring wheels. The inner ring wheel is connected to a friction plate arranged on the installation gap. In the radial direction of the anti-tilt roller, the size of the friction plate is smaller than that of the outer ring wheel. There are multiple outer ring wheels, and installation gaps are arranged between each outer ring wheel. A friction plate is also arranged on the inner ring wheel, and the friction plate is arranged inside the installation gap. Since the friction plate is connected to the inner ring wheel, when the elastic block is squeezed, the inner ring wheel drives the friction plate to move synchronously relative to the outer ring wheel. When the deformation of the elastic block is large enough, the friction wheel can be close to the lower rail surface and fit together with the lower rail surface. The friction wheel is made of a material with a high friction coefficient. When the friction wheel fits the lower rail surface, the friction force is significantly improved, thereby quickly reducing the vehicle speed and feeding back to the traction device to ensure the smooth operation of the vehicle.

[0012] Preferably, the friction plate is a polygon, and the friction plate is rotatably connected to the inner ring wheel. The friction plate is set to a polygon, and the friction plate is rotatably connected to the inner ring wheel. After the elastic block is squeezed, the inner ring wheel drives the friction wheel to move radially. After the friction wheel abuts the lower rail surface, since the friction wheel is rotatably connected to the inner ring wheel and is a polygon, the friction wheel adaptively fits one side with the lower rail surface. At this time, since the friction wheel and the lower rail surface are in full contact, the friction force is large, and the fit between the friction wheel and the lower rail surface can be maintained when the inclination remains unchanged, so the vehicle speed can be quickly reduced. When the vehicle speed is reduced to, the friction wheel is separated from the lower rail surface, indicating that the inclination of the RGV is within a controllable range, and the vehicle speed is reduced by the friction between the outer ring wheel and the lower rail surface, and the feedback traction device is used to achieve stable dynamic control of the vehicle speed.

[0013] Preferably, a guide wheel assembly is also included, the guide wheel assembly includes a guide roller, the track includes a side track surface, and the guide roller abuts the side track surface. In this device, a guide wheel assembly is also provided, and the guide wheel assembly abuts against the side track surface of the track, which can provide a guide function for the RGV during movement and ensure the smoothness of the vehicle operation.

[0014] Preferably, the guide wheel assembly includes a positioning shaft, one end of which is connected to the rail vehicle body, and the other end is rotatably connected to the guide roller, and the positioning shaft is an offset shaft. The guide wheel assembly includes a positioning shaft, wherein the positioning shaft connects the rail vehicle body and the guide roller. Preferably, the positioning shaft is an offset shaft, that is, the part connected to the rail vehicle body and the part connected to the guide roller are eccentrically arranged, so that it can flexibly adapt to different guide rollers and rails, and can avoid insufficient fitting caused by dimensional errors during installation.

[0015] Preferably, the side roller assembly includes a connecting shaft, one end of which is connected to the lateral mounting seat, and the other end is connected to a transmission bearing, the transmission bearing is connected to the anti-dumping roller, and the end of the connecting shaft away from the lateral mounting seat is connected to a bearing retaining ring, the bearing retaining ring abuts the transmission bearing. The rotation flexibility of the anti-dumping roller is improved by connecting the transmission bearing, and the transmission bearing is prevented from falling off by connecting the bearing retaining ring.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) It can improve the running stability of RGV on the track, avoid rollover, and ensure the safety of cargo transportation;

[0018] (2) It can ensure close fit between the anti-dumping roller and the lower rail surface, thereby improving the stability of operation;

[0019] (3) Ensure that the RGV has good guiding performance and avoid applying excessive pressure on the anti-dump rollers;

[0043] The assembly and working process of the RGV anti-dumping roller device in the embodiment are as follows: in the present embodiment, a lateral mounting seat is connected under the rail vehicle body 1, wherein the angled mounting plate 31 of the lateral mounting seat is connected to the rail vehicle body 1 by bolts, and in the present embodiment, a connecting hole is provided on the positioning plate 311, wherein the connecting hole is a waist-shaped hole, and the bolt passes through the connecting hole to be connected to the rail vehicle body 1, wherein an inclination angle is provided between the positioning plate 311 and the connecting plate 312, which is not a 90° vertical setting, and is adapted to the inclination angle setting of the lower rail surface 21, wherein a mounting groove 33 is provided on the connecting plate 312, and the connecting plate 312 is connected to the shaft mounting plate 32, and is tightened by bolts, wherein a thread is provided on one end of the connecting shaft 42 close to the shaft mounting plate 32, and a cutting edge is also provided on the connecting shaft 42, which is convenient for operation with a wrench, and a transmission bearing 43 is connected to the side of the connecting shaft 42 away from the shaft mounting plate 32, and a bearing retaining ring 44 is abutted against the side of the transmission bearing 43 away from the shaft mounting plate 32, wherein the bearing The retaining ring 44 is connected to the connecting shaft 42, and the transmission bearing 43 is connected to the anti-dumping roller 41, which abuts against the lower rail surface 21.

[0044] Embodiment 2:

[0045] like Figure 7As shown, the present embodiment includes: an RGV anti-dumping roller device, including a rail vehicle body 1, the rail vehicle body 1 is slidably connected to the rail 2, the rail vehicle body 1 is connected to a lateral mounting seat, the lateral mounting seat is connected to a side roller group 4, the rail 2 includes a lower rail surface 21, the side roller group 4 includes an anti-dumping roller 41 abutting against the lower rail surface 21, the lateral mounting seat 3 includes an angled mounting plate 31, the angled mounting plate 31 includes a positioning plate 311 and a connecting plate 312, the positioning plate 311 is connected to the rail vehicle body 1, the connecting plate 312 is connected to the side roller group 4, the lower rail surface 21 is inclined, the connecting plate 312 is inclined compared to the positioning plate 311, the inclination angle of the connecting plate 312 corresponds to the inclination angle of the lower rail surface 21, the anti-dumping roller 41 is abutted against the lower rail surface 21 fits, the lateral mounting seat includes an axis mounting plate 32 connected to the connecting plate 312, and the connecting plate 312 is provided with a mounting groove 33. The side roller group 4 includes a connecting shaft 42, one end of the connecting shaft 42 is connected to the lateral mounting seat, and the other end is connected to a transmission bearing 43, the transmission bearing 43 is connected to the anti-dumping roller 41, and the end of the connecting shaft 42 away from the lateral mounting seat is connected to a bearing retaining ring 44, and the bearing retaining ring 44 abuts the transmission bearing 43.

The guide wheel assembly 5 includes a positioning shaft 52, one end of the positioning shaft 52 is connected to the rail vehicle body 1, and the other end is rotatably connected to the guide roller 51, and the positioning shaft 52 is an offset shaft.

[0046] Preferably, in this embodiment, the anti-dump roller 41 includes an inner ring wheel 411 and an outer ring wheel 412, an elastic block 413 is connected between the inner ring wheel 411 and the outer ring wheel 412, the outer ring wheel 412 abuts against the lower rail surface 21, and the side roller group 4 includes a connecting shaft 42, and the inner ring wheel 411 is connected to the connecting shaft 42.

Due to the deformability of the elastic block 413, when it is slightly squeezed and deformed, the anti-dumping roller 41 can maintain relative rolling, and when the compression amount of the elastic block 413 reaches a large amount, it will cause the inner ring wheel 411 and the outer ring wheel 412 to rotate relative to each other. The eccentricity is relatively large, and the anti-dump roller 41 is not easy to roll at this time.

Since the anti-dump roller 41 is connected to the lower rail surface 21 of the track 2, the anti-dump roller 41 will not be squeezed during normal working. Only when a tilting tendency occurs, as the tilting force gradually increases, the elastic block 413 is continuously squeezed, resulting in a gradual increase in the eccentricity between the inner ring wheel 411 and the outer ring wheel 412, thereby causing the anti-dump roller to be unable to rotate normally, the friction force becomes larger, the vehicle speed is reduced, and feedback is given to the traction device to reduce the vehicle speed.

When the RGV is installed on different tracks 2, different angled mounting plates 31 can be replaced to adapt, thereby improving the flexibility and adaptability of the RGV. The inclination angle is set corresponding to the inclination angle of the lower rail surface 21, so as to ensure that the anti-dump roller 41 can fit well with the lower rail surface 21, thereby improving the stability of the vehicle, and can obtain a certain guiding ability through the anti-dump roller 41, thereby improving the stability of operation, and the lateral mounting seat includes an axle mounting seat connected to the connecting plate 312, wherein the axle mounting seat is used to fix the connecting shaft 42, wherein a mounting groove 33 is provided on the connecting plate 312, which can avoid the connection and installation between the connecting shaft 42 and the axle mounting seat, and facilitate installation, and improve the rotation flexibility of the anti-dump roller 41 by connecting the transmission bearing 43, and the connecting shaft 42 is supported by a retaining ring to prevent the transmission bearing 43 from falling off. A guide wheel assembly 5 is also provided in the present device. The guide wheel assembly 5 is in contact with the side rail surface 22 of the track 2, and can provide a guide function for the RGV during movement to ensure the smoothness of the vehicle operation.
