Description

Technical Field

[0001] This utility model relates to the field of car carrier technology, specifically a car carrier with an automatic ramp. Background Technology

[0002] Car carriers are vehicles used for bulk transportation of multiple cars, serving as automotive logistics and transport services. The ramp of a car carrier is a support mechanism installed at the rear of the vehicle that can tilt and extend to the ground, forming a ramp between the ground and the flatbed for loading, unloading, and movement of the cars. Most existing car carrier ramp mechanisms are manually operated, requiring manual deployment by loading and unloading personnel, which is time-consuming, labor-intensive, and inefficient. Some car carriers have electrically operated ramps, but the extension and opening of the rear frame is still manual, also presenting time-consuming, labor-intensive, and inefficient problems. To address these issues, we provide a car carrier with an automatic ramp. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a car carrier with an automatic ramp, which solves the problem that the ramp mechanism of most existing car carriers is manually operated, and some car carriers have electric ramp mechanism with electric tilting but manual extension of the tail frame. This requires manual operation for loading and unloading, which is time-consuming, labor-intensive and inefficient.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a car carrier with an automatic ramp, comprising a frame and a ramp mechanism. The rear of the frame is provided with an upper crossbeam and a lower crossbeam. The ramp mechanism includes two sets of symmetrically distributed main frames and a tail frame slidably disposed within the main frames. The two sets of main frames are fixedly connected by a connecting beam one, and the two sets of tail frames are fixedly connected by a connecting beam two. The connecting beam one and the connecting beam two are respectively hinged to both ends of a long-stroke hydraulic cylinder. The long-stroke hydraulic cylinder is arranged along the length extension direction of the ramp mechanism. One end of the main frame is hinged to the upper crossbeam, and the tail frame is driven by the long-stroke hydraulic cylinder to extend out at the other end of the main frame. The main frame and the lower crossbeam are respectively hinged to both ends of a tilting drive mechanism. The tilting drive mechanism is diagonally supported between the main frame and the lower crossbeam, and the tilting drive mechanism is located below the main frame.

[0005] Preferably, a connecting beam three is fixedly connected between the two sets of main frames, and a bracket is fixedly connected to the connecting beam three, which supports the housing of the long-stroke hydraulic cylinder.

[0006] Preferably, the long-stroke hydraulic cylinder is positioned between the two main frames.

[0007] Preferably, the tilting drive mechanism includes a tilting hydraulic cylinder, an outer sleeve, an inner sleeve, a first connecting seat, a second connecting seat, and a third connecting seat. The inner sleeve is slidably disposed inside the outer sleeve along the length direction of the outer sleeve. The end of the outer sleeve is hinged to the lower crossbeam via the first connecting seat. The end of the telescopic end of the inner sleeve is hinged to the main frame via the second connecting seat. The tilting hydraulic cylinder is disposed parallel to the outer sleeve. One end of the tilting hydraulic cylinder is hinged to the first connecting seat, and the other end of the tilting hydraulic cylinder is hinged to the inner sleeve via the third connecting seat.

[0008] Preferably, the angles between the flipping drive mechanism and the main frame and the lower crossbeam are both acute angles.

[0009] This utility model has the following beneficial effects:

[0010] This invention uses a long-stroke hydraulic cylinder and a tilting drive mechanism to drive the tilting and extension of the ramp mechanism. The tilting drive mechanism controls the angle adjustment of the ramp mechanism, and the long-stroke hydraulic cylinder drive mechanism controls the length adjustment of the ramp mechanism. This allows the ramp mechanism to be connected to the frame at one end and extended diagonally downwards to the ground at the other end, forming a ramp between the ground and the flatbed truck for loading and unloading vehicles. It automatically unfolds and retracts without manual operation, resulting in high efficiency and saving time and labor. Attached Figure Description

The ramp mechanism 2 includes two sets of main frames 21 symmetrically distributed on the left and right, and a tail frame 22 slidably disposed within the main frames 21. The two sets of main frames 21 are fixedly connected by a connecting beam 1 23, and the two sets of tail frames 22 are fixedly connected by a connecting beam 24. The connecting beam 1 23 and the connecting beam 24 are respectively hinged to both ends of a long-stroke hydraulic cylinder 25. A connecting beam 3 2 is also fixedly connected between the two sets of main frames 21. 7. A bracket 271 is fixedly connected to the connecting beam 27. The bracket 271 supports the housing of the long-stroke hydraulic cylinder 25. The long-stroke hydraulic cylinder 25 is set along the length extension direction of the ramp mechanism 2. The long-stroke hydraulic cylinder 25 is set in the middle of the two sets of main frames 21. One end of the main frame 21 is hinged to the upper crossbeam 3. The tail frame 22 is driven by the long-stroke hydraulic cylinder 25 to extend out at the other end of the main frame 21. The main frame 21 and the lower crossbeam 4 are respectively hinged to the two ends of the tilting drive mechanism 26. The tilting drive mechanism 26 is diagonally supported between the main frame 21 and the lower crossbeam 4, and the tilting drive mechanism 26 is located below the main frame 21.
