Description

Technical Field

[0001] This invention relates to the field of vehicle transfer device technology, and more specifically to a device for transferring vehicles in a workshop. Background Technology

[0002] A workshop transfer device is a mechanical device used to transport vehicles (such as electric vehicles, cars, and tricycles) in manufacturing workshops, warehousing and logistics scenarios. Its main function is to efficiently and safely transfer vehicles from one workstation to another to improve the continuity and automation level of the production process. Traditional transfer devices usually adopt a fixed structure and rely on manual operation or simple mechanical devices to load, unload and fix vehicles. However, when faced with different vehicle models and different load requirements, they often have problems such as poor adaptability, low efficiency and insufficient stability. Currently, the main technical solutions for workshop transfer devices include: Fixed limiting device: It uses rigid baffles or slots to limit the wheels, but it is only suitable for vehicles with a specific wheel track and cannot be adjusted flexibly; Manual adjustment mechanism: The limit width is adjusted by mechanical structures such as bolts and pins, but the operation is cumbersome and inefficient; Hydraulic lifting platform: The platform is raised and lowered using hydraulic cylinders, which facilitates vehicle loading and unloading, but it lacks the function of actively securing the vehicle and is prone to displacement during transportation. However, although existing technologies can meet basic transportation needs to some extent, the following key shortcomings still exist: Poor vehicle adaptability: The fixed limiting structure cannot be adapted to vehicles with different wheelbases (such as four-wheeled vehicles and three-wheeled vehicles), which leads to the need to equip multiple sets of transfer devices, increasing costs and management difficulty.

[0003] Low loading and unloading efficiency: Relying on manual adjustment of limit devices or manual fixing of vehicles, the operation steps are cumbersome and affect the overall logistics efficiency. Summary of the Invention

[0032] Spacing adaptation: Electric lead screw 2 604 drives two support blocks 606 to move synchronously in opposite directions, and the spacing of the carrier plate 602 is adapted to the wheel track; Electric lead screw 1 and 2 are both composed of motors and lead screws. The motor drives the lead screw to rotate, thereby driving the structure on the lead screw.

[0033] The surface of the carrier plate 602 is provided with rubber anti-slip texture to increase friction.

[0034] The traction component 401 is equipped with a winding frame, a geared motor, and a traction rope. Both sides of the support plate 200 are fixedly installed with winding frames, and winding rollers are rotatably installed inside the winding frames. The traction rope is wound on the winding rollers, and the traction end of the traction rope is installed and connected to the mounting shell 421. A geared motor is fixedly installed on one side of the winding frame, and the output end of the geared motor is installed and connected to the winding rollers.

[0035] The geared motor drives the take-up roller through a gear set, and the maximum load of the traction rope is 500 kg; The winding frame is equipped with an overload protector that automatically cuts off power when the tension exceeds the limit.

[0036] Working principle and usage process of this invention: In use, the pneumatic components of the device are electrically connected to the control system inside the platform 501 via wires, and the platform 501 is also equipped with a battery pack for power supply and operation. First, when the device reaches the vehicle's loading point, the device stops driving the drive wheel 502 and starts hydraulic cylinder 212 to raise the positioning plate 211, causing the positioning plate 211 to release its positioning of the support platform 100. Then, hydraulic cylinders 504 and 301 are started simultaneously. Since their operation is synchronized, when hydraulic cylinder 504 drives the support platform 100 to tilt downwards, hydraulic cylinder 301 slides through the end connector 302 and guide pin 304 in the guide port 305, causing the support arm 306 to tilt upwards. During this time, the support platform 100 tilts downwards through the connecting seat 506, causing the end of the support platform 100 to fit against the bottom surface, ready to be loaded onto the vehicle. The second step involves personnel boarding the vehicle according to its type. For a standard four-wheeled vehicle, personnel activate the electric screw 604 to drive the support block 606 in opposite directions, synchronizing the spacing between the carrier plates 602 with the wheel spacing of the vehicle. The vehicle is then guided onto the support platform 100 via the loading port 101. During boarding, the top surface of the carrier plate 602 is flush with the top surface of the support platform 100. Once the vehicle is fully on the support platform 100, the hydraulic cylinder 603 retracts the carrier plate 602, ensuring the rear wheels are within the limiting groove 102. At this point, the carrier plate 602 is in its limiting position. When the bottom of the groove 102 reaches the disembarkation point, personnel can start the hydraulic cylinder 603 to push the carrier plate 602, thereby raising the height of the vehicle's rear wheels to facilitate disembarkation. Then, the electric screw 428 is activated to drive the guide block 424, causing it to move the limiting block 422 on the connecting rod 423 inward. At that time, the limiting block 422 can slide behind the front wheels of the vehicle. Finally, the traction component 401 is activated to pull the traction rope on itself to pull the mounting shell 421, causing the limiting block 422 to come into contact with the front wheels of the vehicle, thereby restricting the front wheels. If it is a tricycle, the operator only needs to drive the front wheel into the groove of the support seat 700, and then activate the traction component 401 to lower the mounting shell 421. Under the action of the tilting force, the mounting shell 421 will roll downwards along the track 429 via the bottom rollers 425 until it reaches the position of the support seat 700. At this point, the electric screw 428 is activated to retract, driving the clamping component 426 on the connecting rod 427 to clamp. The clamping component 426 will then clamp and limit the front wheel of the tricycle. Finally, the traction component 401 is activated to pull the mounting shell 421 back using the traction rope. This will pull the clamped tricycle. Since the front wheels of the tricycle are located within the support seat 700, the support seat 700 will move linearly within the guide groove 104 through the bottom sliding groove 701 under the pulling force. At this time, the entire tricycle will be pulled, and the rear wheels will roll along, reaching the support platform 100 through the loading port 101. When reaching the support platform 100, it is necessary to ensure that the path of the carrier plate 602 is consistent with that of the rear wheels of the tricycle, so that the carrier plate 602 can support them. When it reaches the position of the limit groove 102, the traction component 401 stops, but the clamping state of 462 remains, and the hydraulic cylinder 4603 is activated to drive the carrier plate 602. The device is lowered into the limiting groove 102; Third, after the vehicle is loaded, hydraulic cylinders 504 and 301 can be started. Hydraulic cylinder 504 starts the support platform 100 to flip upward, and hydraulic cylinder 301 starts the support arm 306 to flip downward, so that the support platform 100 enters the balanced state and the front wheel 303 enters the rolling support state. Finally, the drive wheel 502 can be started to drive the entire device to move, and the other rollers move synchronously to assist movement.
