[0002] In industrial production and warehousing logistics, RGV (Automated Guided Vehicle) transport carts have become crucial equipment for material handling due to their high degree of automation and stable operation. In automobile manufacturing plants, RGV carts frequently transport components weighing hundreds of kilograms, such as engines and transmissions. In large warehousing centers, they often carry over half a ton of goods for inbound and outbound transport. Most existing RGV carts can only achieve unidirectional or fixed-route material transport. In electronic component manufacturing workshops, materials need to be flexibly transferred between different processing stations. Traditional unidirectional RGV carts cannot meet the demands of complex operating conditions, often requiring multiple devices to operate simultaneously, increasing equipment investment costs and space occupation, while also reducing material transport efficiency. Therefore, we propose a simplified heavy-duty RGV transport cart. Utility Model Content

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0019] like Figure 1-3As shown, this utility model is a simple heavy-duty RGV transport trolley, including a pillow plate 1, of which multiple pillow plates 1 are provided. Tracks 2 are provided on both sides above the pillow plates 1, and a vehicle body support 3 is provided above the tracks 2. Drive wheel boxes 4 are provided at both ends of one side of the vehicle body support 3, and driven wheel boxes 5 are provided at both ends of the side of the vehicle body support 3 away from the drive wheel boxes 4. An anti-torsion bracket 6 is provided on the side of one drive wheel box 4 near the vehicle body support 3. A power motor 7 is fixedly mounted on the anti-torsion bracket 6. The rotating shaft of the power motor 7 passes through the anti-torsion bracket 6 and is connected to the drive wheel box 4. Two drive wheel boxes 4 are connected by a shaft 8. When the power motor 7 is working, it drives the rollers on the drive wheel box 4 to rotate. Through the transmission of the shaft 8, the rollers on the two drive wheel boxes 4 can rotate synchronously. Through the cooperation between the drive wheel box 4 and the driven wheel box 5, the vehicle body transport trolley can transport RGV ... The transfer trolley can reciprocate horizontally on track 2. Roller transfer line supports 10 are provided on both sides above the trolley body support 3. A roller transfer motor 11 is provided below the roller transfer line support 10. Transfer roller shafts 12 are provided on both sides of the upper end of the roller transfer line support 10. The output end of the roller transfer motor 11 is connected to the transfer roller shaft 12 through a chain 13. The output end of the roller transfer motor 11 and the end of the transfer roller shaft 12 are provided with gears that match the chain 13. When the roller transfer motor 11 is working, the roller transfer motor 11 causes the transfer roller shaft 12 to rotate through the interaction between the gear and the chain 13. Thus, the longitudinal transfer of materials can be completed through the rotating transfer roller shaft 12. Multiple transfer shafts 14 are provided between the two transfer roller shafts 12 on the roller transfer line support 10. Auxiliary transfer cylinders 15 are provided on the transfer shafts 14.
[0020] Side supports 16 are provided on both sides above the vehicle body support 3. A spring positioning post 17 is provided at the middle of the upper end of each side support 16. A tension spring 18 is provided below the spring positioning post 17. The tension spring 18 is fixedly connected to a steel wire rope 19 at its lower end. The steel wire rope 19 is fixedly connected to a counterweight 30 at its lower end. The upper end of the counterweight 30 is movably connected to a long safety contact rod 20 via a pin. The middle of the long safety contact rod 20 is movably connected to the side supports 16 via a pin. When the long safety contact rod 20 rotates, the end of the long safety contact rod 20 near the vehicle body support 3 can trigger a safety contact rod limit switch 2. 2. The upper end of the wire rope 19 is provided with two short safety contact rods 21. The end of the short safety contact rod 21 away from the wire rope 19 is movably connected to the side bracket 16. When the short safety contact rod 21 and the wire rope 19 are touched, the long safety contact rod 20 will also rotate, thereby triggering the safety contact rod limit switch 22. When a person accidentally touches the long safety contact rod 20, the short safety contact rod 21 or the wire rope 19, the safety contact rod limit switch 22 will be automatically triggered, thereby causing the control system inside the trolley to immediately cut off the power or start the emergency brake, forcing the trolley to stop.
[0021] The vehicle body bracket 3 is equipped with a safety contact rod limit switch 22 on the side near the long safety contact rod 20.
[0022] The vehicle body support 3 is provided with a drag chain 9 on the side near the power motor 7, and the end of the drag chain 9 away from the vehicle body support 3 is fixedly connected to the track 2.
[0023] Shock absorbers 23 are provided at both ends of the track 2. The shock absorbers 23 can reduce the mechanical vibration and impact of the heavy-duty RGV trolley when it moves to the end of the track 2.
[0024] A sensor plate 24 is provided in the middle of the lower part of the vehicle body support 3. Multiple proximity sensors 25 are arranged at equal intervals in the track 2. A limit switch 26 is provided on the track 2. When the sensor plate 24 on the RGV trolley approaches the proximity sensor 25, the proximity sensor 25 is triggered, and the RGV trolley begins to decelerate. The specific number and position of the proximity sensors 25 can be determined according to the specific work station where the material is to be conveyed.
[0025] A photoelectric sensor 27 is fixedly installed on the vehicle body support 3. A photoelectric sensor sensing block 28 matching the photoelectric sensor 27 is provided between the two tracks 2. The photoelectric sensor 27 ensures that the RGV trolley stops accurately at the material transfer station. When the photoelectric sensor sensing block 28 triggers the photoelectric sensor 27, the RGV trolley stops immediately and the material transfer begins. The specific number and position of the photoelectric sensor sensing blocks 28 are determined according to the specific station where the material is to be transferred.
[0026] The track 2 is fixedly installed above the sleeper plate 1 by mounting pressure block 29.
[0027] Specifically, in this utility model, when the power motor 7 is working, it drives the rollers on the drive wheel box 4 to rotate. Through the transmission of the shaft 8, the rollers on the two drive wheel boxes 4 can rotate synchronously. Through the cooperation between the drive wheel box 4 and the driven wheel box 5, the transfer trolley can move back and forth horizontally on the track 2. When the roller transfer motor 11 is working, the roller transfer motor 11, through the cooperation between the gear and the chain 13, causes the transfer roller shaft 12 to rotate as well. Thus, the longitudinal transfer of materials can be completed through the rotating transfer roller shaft 12. The short safety contact rod 21 is used to... When the wire rope 19 is touched, the long safety contact rod 20 also rotates, which triggers the safety contact rod limit switch 22. When a person accidentally touches the long safety contact rod 20, the short safety contact rod 21, or the wire rope 19, the safety contact rod limit switch 22 will be automatically triggered, causing the control system inside the trolley to immediately cut off the power or activate the emergency brake, forcing the trolley to stop. When the photoelectric sensor block 28 triggers the photoelectric sensor 27, the RGV trolley stops immediately, and the material begins to be transported. The specific number and position of the photoelectric sensor blocks 28 are determined according to the specific workstation where the material is to be transported.
