Description

Technical Field

[0001] The utility model relates to the technical field of flatbed transport vehicles, in particular to a flatbed transport vehicle with a boarding ramp. Background Art

[0002] In the field of modern engineering transportation, flatbed trucks are a vital load-bearing tool. They are widely used to transport various large, non-detachable objects. In order to meet the transportation needs of these large mechanical equipment, the loading ramp is located at the rear of the vehicle. It is a device that provides an ascending ramp, allowing large mechanical equipment to easily drive on or off the transport vehicle. This design greatly simplifies the loading and unloading process, reduces dependence on additional lifting equipment or manpower, and improves transportation efficiency and safety.

[0003] However, there is an angle between the existing boarding bridge and the rear of the carriage. When the vehicle moves from the boarding bridge to the carriage, the angle will cause the bottom of the vehicle to contact the bottom of the carriage, which may cause damage to the bottom of the vehicle or scratches on the body of the vehicle. In order to avoid this situation, staff usually need to adjust the angle of the boarding bridge to keep it parallel or as close to parallel as possible with the bottom of the vehicle. Excessive adjustment of the angle of the boarding bridge may cause operational inconvenience and even increase loading and unloading time and cost. Therefore, there is a problem of inconvenience in moving the car into the carriage. Utility Model Content

Starting the first electric telescopic rod 206 facilitates the adjustment of the angle between the fixed frame 204 and the rotating plate 205, and thus facilitates the movement of the vehicle onto the boarding plate 202.

[0026] A hydraulic telescopic column 209 is hinged on the outer surface of the vehicle body 1, and the other end of the hydraulic telescopic column 209 is hinged on the outer surface of the vehicle compartment 4. Starting the hydraulic telescopic column 209 facilitates adjustment of the angle of the vehicle compartment 4, so that the boarding plate 202 can slide toward the ground, thereby facilitating the transportation of the vehicle into the vehicle compartment 4.

[0029] It is worth mentioning that when the car slides upward along the outer surface of the limiting groove 301, the front wheel of the car squeezes the outer surface of the barrier rod 302, causing the barrier rod 302 to rotate on the outer surface of the connecting frame 304 and the spring 303 to stretch. When the front wheel of the car slides to the top of the limiting groove 301, the barrier rod 302 and the tire of the car are separated, thereby causing the spring 303 to contract and the barrier rod 302 to return to its original position, thereby facilitating the limiting of the front wheel of the car.

[0030] Working principle: start the hydraulic telescopic column 209, the output end of the hydraulic telescopic column 209 drives the carriage 4 to rotate on the upper surface of the car body 1, and then start the reduction motor 201, the output shaft of the reduction motor 201 drives the threaded rod 203 to rotate, the threaded rod 203 rotates and drives the boarding plate 202 to slide on the outer surface of the carriage 4, so that the lower surface of the boarding plate 202 slides on the outer surface of the multiple groups of support rollers 208, so that one end of the boarding plate 202 can extend above the ground, and then start the first electric telescopic rod 206, the output end of the first electric telescopic rod 206 drives the rotating plate 205 to rotate on the outer surface of the fixed frame 204, so that the outer surface of the rotating plate 205 fits with the ground, which is convenient for moving the car to the upper surface of the boarding plate 202, so that the car The four tires of the car slide into the limiting groove 301. When the car slides upward along the outer surface of the limiting groove 301, the front wheel of the car squeezes the outer surface of the blocking rod 302, so that the blocking rod 302 rotates on the outer surface of the connecting frame 304, and the spring 303 is stretched.
