Description

Technical Field

[0001] The utility model belongs to the technical field of RGV shuttle vehicle systems, and in particular relates to a heavy-duty RGV shuttle vehicle system with high-speed and stable transportation. Background Art

[0002] The RGV rail-mounted shuttle is a state-of-the-art material handling solution for factories and logistics systems. Known for its high speed, reliability, and efficiency, it comes in two main types: the Assembly RGV system and the Transport RGV system. This powerful shuttle is designed to meet a variety of applications, including material transport and shop floor assembly. It offers flexible movement and workflow. The heavy-duty RGV can adapt to various handling needs and is widely used in manufacturing, warehousing, supply chain management, and other fields. This shuttle system is a heavy-duty RGV system, designed to handle a maximum weight capacity of 5 tons.

[0003] The utility model patent with domestic application number 201821749309.0 discloses a heavy-duty RGV height-limited shuttle vehicle, including a frame, a control device, a walking device, and a lifting device. The frame is a rectangular parallelepiped, and both sides of the bottom of the frame are connected with a walking device at a farther distance. The walking device includes a walking motor, a walking reducer, a walking drive shaft, and a walking drive wheel. The walking reducer is sleeved and connected to the walking drive shaft. Both ends of the walking drive shaft are connected to the walking drive shaft. The lifting device includes a lifting plate, a coupling, a lifter, a lifting motor, a lifting reducer, a lifting drive shaft, and a steering gear. The lifting reducer is sleeved and connected to the lifting drive shaft. Both ends of the lifting drive shaft are connected to the steering gear. Each steering gear is penetrated by a lifting driven shaft perpendicular to the lifting drive shaft. Both ends of each lifting driven shaft are connected with a coupling. Each coupling is connected to an elevator, and each elevator is provided with a lifting screw that penetrates the frame and connects to the lifting plate. The aforementioned utility model incorporates a lift to achieve a lifting effect during the transport process, adjusting to height restrictions. However, in actual use, due to its heavy-duty RGV shuttle system, changes in speed or cornering during transport can cause wobbling. The centrifugal force exerted by the load on top can cause the RGV shuttle itself to shift, temporarily separating the wheels of its bottom running structure from the track. This can easily lead to derailment, affecting the normal use of the RGV shuttle. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a heavy-duty RGV shuttle system with high-speed and stable transportation, including a conveying rail structure installed on the ground, an end frame fixedly installed at the end of the conveying rail structure, a shuttle main frame that travels on the top of the conveying rail structure, four sets of shuttle wheel bodies fixedly installed at the bottom of the shuttle main frame and rotating on the top of the conveying rail structure, and a drive motor fixedly installed on one group of the shuttle wheel bodies for driving them to rotate.

[0005] As a further preferred technical solution of the present invention, the conveyor rail structure includes a track, positioning brackets mounted on both sides of the track bottom, and chemical bolts penetrating the positioning brackets and attached to the ground. The chemical bolts penetrate the positioning brackets and secure the conveyor rail structure to the ground. A crash barrier is fixedly mounted on the bottom of the shuttle vehicle main frame, located at one end outside the shuttle wheel body.

[0006] The conveyor rail structure is installed in the corresponding position according to the setting position of the RGV shuttle system to facilitate the shuttle transportation of the RGV shuttle system.

[0007] As a further preferred technical solution of the present invention, the track includes a top rolling surface at the top and lateral rolling grooves on both sides.

[0008] The lateral rolling grooves are recessed. This RGV shuttle system is a heavy-duty RGV shuttle system designed for a maximum load capacity of 5 tons. The lateral rolling grooves ensure a tight fit between the shuttle wheels and the sides of the conveyor rails during sliding, minimizing the risk of the RGV derailing or tipping over due to centrifugal force.

[0009] As a further preferred technical solution of the present invention; a docking plate is welded to the top of the shuttle wheel body and fixedly installed with the bottom of the shuttle main frame, and an installation box is connected to the bottom of the docking plate, and a walking wheel body is rotatably installed inside the installation box, and side panels are fixedly installed on both sides of the installation box by fixing bolts, and a tripod is welded to the side panel, and two sets of auxiliary wheel mechanisms are installed through the tripod.

[0010] The shuttle wheel body consists of a set of running wheel bodies inside the installation box and four sets of auxiliary wheel mechanisms. The running wheel bodies cooperate with the top rolling surface to run normally on the top of the conveyor rail structure, while the auxiliary wheel mechanisms cooperate with the lateral rolling grooves to run. In this way, when the load is high, the fit between the shuttle wheel body and the conveyor rail structure is ensured during travel, avoiding the RGV shuttle vehicle from overturning during curve driving.

[0011] As a further preferred technical solution of the present invention, T-frames are installed at both ends of the traveling wheel body, and the inner sides of the T-frames are fixedly mounted to the traveling wheel body via bearings. Two sets of movable openings are provided on the installation box, and a connecting rod is connected and installed on one side of the T-frame, and the connecting rod is arranged to pass through the movable opening. A welding plate is fixedly mounted on the installation box at the bottom position of the movable opening, and a shock-absorbing spring is fixedly mounted on the welding plate. A protective frame is fixedly mounted on the end of the connecting rod via bearings. The protective frame is fixedly mounted to the top of the shock-absorbing spring, and its bottom extends to the outside of the welding plate.

[0012] When the traveling wheel body is rotated by the driving force, during the conveying process, due to its heavy weight, the shock-absorbing spring has a certain shock-absorbing effect, which produces a certain protective effect on the traveling wheel body itself, avoiding the situation where the bottom of the traveling wheel body and the top of the conveying rail structure are worn out too much and affect the conveying efficiency.

[0013] As a further preferred technical solution of the present invention, two sets of connecting openings are provided between the bottom of the side panels and the tripod. Side wheels are installed inside the auxiliary wheel mechanism at the bottom of the tripod, and the side wheels are fixed to the tripod via mounting bolts. A connecting frame is fixedly installed at one end of the auxiliary wheel mechanism through the connecting opening, and an X-welded frame is connected and installed between the connecting frames. A rotating shaft is installed in the middle of the X-welded frame, and two sets of wedge-shaped load-bearing bodies are connected and installed on the top of the X-welded frame. An auxiliary inclined surface is provided at the top of the T-frame, and the auxiliary inclined surface is arranged to fit in place with the bottom of the wedge-shaped load-bearing body.

[0014] During the RGV shuttle's transportation process, the heavy load on the top causes some shaking when passing through curves, resulting in a brief separation between the bottom of the running wheel and the conveyor rail structure. As the running wheel is forced upward, the auxiliary inclined surface squeezes the wedge-shaped load-bearing body, tightening the bottom of the X-welded frame inward. This increases the fit between the side wheels and the lateral rolling grooves, preventing the RGV shuttle from leaving the track and tipping over, and ensuring the stability of the heavy-duty RGV shuttle's transportation.

[0015] As a further preferred technical solution of the present invention, the walking wheel body includes a rotating wheel, a spring group fixedly installed on the outer circle of the rotating wheel, and an outer ring shell located on both sides of the rotating wheel and fixedly installed on the other end of the spring group.

[0016] By setting the spring group, the traveling wheel body itself has a certain buffering effect when transporting heavy goods, thereby reducing the wear of the traveling wheel body.

[0017] As a further preferred technical solution of the present invention, an electric control box is fixedly installed on one end of the top of the shuttle vehicle main frame.

[0018] The RGV shuttle system is controlled and driven by the electronic control system inside the electronic control box.

[0019] Beneficial effects

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. During the RGV shuttle's transportation process, when the speed changes or when passing through a curve, the heavy load on the top will cause a certain amount of shaking, resulting in a brief separation between the bottom of the running wheel and the conveyor rail structure. When the running wheel is forced upward, the auxiliary inclined surface squeezes the wedge-shaped load-bearing body, tightening the bottom of the X-welded frame inward, thereby increasing the fit between the side wheels and the lateral rolling grooves, preventing the RGV shuttle from leaving the track and overturning, and ensuring the stability of the heavy-duty RGV shuttle transportation.

[0022] 2. The shuttle wheel body consists of a set of running wheel bodies installed inside the box and four sets of auxiliary wheel mechanisms. The running wheel body cooperates with the top rolling surface to run normally on the top of the conveyor rail structure, while the auxiliary wheel mechanism cooperates with the lateral rolling groove to run. The design load capacity of this utility model is 5t. Therefore, when the load capacity is high, the running wheel body and the conveyor rail structure fit closely, ensuring the stability between the shuttle wheel body and the conveyor rail structure during travel, and avoiding the RGV shuttle car from overturning during travel on curves.

DETAILED DESCRIPTION

[0033] This specific embodiment is a heavy-duty RGV shuttle system with high-speed and stable transportation.

[0034] The aforementioned utility model incorporates a lift to achieve a lifting effect during the transport process, adjusting to height restrictions. However, in actual use, due to its heavy-duty RGV shuttle system, changes in speed or cornering during transport can cause wobbling. The centrifugal force exerted by the load on top can cause the RGV shuttle itself to shift, temporarily separating the wheels of its bottom running structure from the track. This can easily lead to derailment, affecting the normal use of the RGV shuttle.

[0035] Its structural diagram is as follows Figures 1-4As shown. A heavy-duty RGV shuttle system with high-speed and stable transportation includes a conveyor rail structure 2 installed on the ground. The conveyor rail structure 2 includes a track 23, a positioning frame 22 installed on both sides of the bottom of the track 23, and a chemical bolt 21 that penetrates the positioning frame 22 and is installed on the ground. The conveyor rail structure 2 is fixed to the ground through the chemical bolt 21 that penetrates the positioning frame 22. An anti-collision strip 41 is fixedly installed at one end of the shuttle wheel body 4 at the bottom of the shuttle main frame 3. The conveyor rail structure 2 is installed in a corresponding position according to the setting position of the RGV shuttle system to facilitate the shuttle transportation of the RGV shuttle system. The track 23 includes a top rolling surface 231 at the top and lateral rolling grooves 232 on both sides. The lateral rolling grooves 232 are recessed grooves. The RGV shuttle of the utility model is a heavy-duty RGV shuttle system with a maximum design load of 5 tons. When the conveying rail structure 2 cooperates with the shuttle wheel body 4 to make the RGV shuttle slide, according to the setting of the lateral rolling groove 232, the shuttle wheel body 4 and the side of the conveying rail structure 2 are more closely fitted, thereby reducing the situation where the RGV shuttle deviates from the track or overturns due to centrifugal force.

[0036] The shuttle wheel assembly comprises an end frame 1 fixedly mounted at the end of the conveyor rail structure 2, a shuttle main frame 3 that travels on top of the conveyor rail structure 2, and four sets of shuttle wheel bodies 4 fixedly mounted at the bottom of the shuttle main frame 3 and rotatable on top of the conveyor rail structure 2. A docking plate 42 is welded to the top of the shuttle wheel body 4 and fixedly mounted to the bottom of the shuttle main frame 3. A mounting box 43 is connected to the bottom of the docking plate 42, and a running wheel body 7 is rotatably mounted inside the mounting box 43. Side panels 44 are fixedly mounted on both sides of the mounting box 43 via fixing bolts. A tripod 442 is welded to the side panels 44, and two sets of auxiliary wheel mechanisms 45 are installed through the tripod 442. The shuttle wheel body 4 consists of a set of running wheel bodies 7 inside an installation box 43 and four sets of auxiliary wheel mechanisms 45. The running wheel body 7 cooperates with the top rolling surface 231 to travel normally on the top of the conveying rail structure 2, while the auxiliary wheel mechanism 45 cooperates with the lateral rolling groove 232 to travel. The design load capacity of the utility model is 5t. Therefore, when the load capacity is high, the running wheel body 7 fits closely with the conveying rail structure 2, ensuring the stability between the shuttle wheel body and the conveying rail structure 2 during travel, and avoiding the RGV shuttle car from overturning during travel on curves.

[0037] Its structural diagram is as follows Figure 5-Figure 9As shown. T-frames 435 are installed at both ends of the traveling wheel body 7, and the inner side of the T-frame 435 is fixed to the traveling wheel body 7 through bearings. Two sets of movable openings 434 are opened on the installation box 43, and a connecting rod 436 is connected and installed on one side of the T-frame 435, and the connecting rod 436 is set through the movable opening 434. A welding plate 433 is fixedly installed at the bottom position of the movable opening 434 on the installation box 43, and a shock-absorbing spring 432 is fixedly installed on the welding plate 433. A protective frame 431 is fixedly installed on the end of the connecting rod 436 through a bearing. The protective frame 431 is fixedly installed on the top of the shock-absorbing spring 432, and its bottom extends to the outside of the welding plate 433. When the traveling wheel body 7 is rotated by the driving force, during the conveying process, due to its heavy weight, the shock-absorbing spring 432 has a certain shock-absorbing effect, which produces a certain protective effect on the traveling wheel body 7 itself, avoiding the situation where the bottom of the traveling wheel body 7 and the top of the conveying rail structure 2 are worn out and affect the conveying efficiency.

[0038] Two sets of connecting openings 441 are defined between the bottom of the side panels 44 and the tripod 442. Inside the auxiliary wheel mechanism 45, side wheels 451 are mounted at the bottom of the tripod 442. These side wheels 451 are fixed to the tripod 442 via mounting bolts 452. A connecting frame 453 is fixedly mounted on one end of the auxiliary wheel mechanism 45 through the connecting opening 441. X-welded frames 454 are attached to each connecting frame 453. A rotating shaft 455 is mounted in the middle of the X-welded frames 454. Two sets of wedge-shaped load-bearing bodies 456 are attached to the top of the X-welded frames 454. Auxiliary inclined surfaces 437 are provided at the top of the T-shaped frames 435, which are aligned with the bottoms of the wedge-shaped load-bearing bodies 456. During the RGV shuttle's transportation process, when the speed changes or when passing through a curve, the heavy load on the top can cause some shaking, resulting in a temporary separation between the bottom of the running wheel 7 and the conveyor rail structure 2. When the running wheel 7 is forced upward, the auxiliary inclined surface 437 compresses the wedge-shaped load-bearing body 456, tightening the bottom of the X-welded frame 454 inward. This increases the fit between the side wheels 451 and the lateral rolling groove 232, preventing the RGV shuttle from derailing and tipping over, and ensuring the stability of heavy-duty RGV shuttle transportation. The running wheel 7 comprises a rotating wheel 71, a spring assembly 73 fixedly mounted on the outer ring of the rotating wheel 71, and an outer ring housing 72 located on both sides of the rotating wheel 71 and fixed to the other end of the spring assembly 73. The arrangement of the spring assembly 73 provides a certain cushioning effect when transporting heavy cargo, thereby reducing wear on the running wheel 7. The running wheel 7 also includes a drive motor 5 fixedly mounted on a set of shuttle wheel bodies 4 to drive their rotation. An electrical control box 6 is fixedly mounted on one end of the shuttle main frame 3. The electrical control system within the electrical control box 6 controls and drives the RGV shuttle system.

[0039] When the RGV shuttle system is in use, it transports items with a design weight of up to 5 tons. The drive motor 5 is controlled by the electronic control system within the electronic control box 6, causing the running wheel 7 to operate normally on the top of the conveyor rail structure 2 in conjunction with the top rolling surface 231, while the auxiliary wheel mechanism 45 operates in conjunction with the lateral rolling groove 232. During the RGV shuttle's transportation process, when the speed changes or when passing through a curve, the heavy load on the top will cause some shaking, resulting in a temporary separation between the bottom of the running wheel 7 and the conveyor rail structure 2. When the running wheel 7 is forced to move upward, the auxiliary inclined surface 437 squeezes the wedge-shaped load-bearing body 456, tightening the bottom of the X-welded frame 454 inward, thereby increasing the fit between the side wheel 451 and the lateral rolling groove 232, preventing the RGV shuttle from derailing and tipping over, and ensuring the stability of the heavy-duty RGV shuttle's transportation.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
