[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a fixed hydraulic luffing loading ramp includes a bottom support 1, with a main bridge plate 2 hinged to the rear of the bottom support 1. The front end of the main bridge plate 2 is used to connect with the carriage, and the rear end is used to connect with the platform 8. A hydraulic cylinder 3 is hinged between the bottom support 1 and the main bridge plate 2, and the hydraulic cylinder 3 drives the main bridge plate 2 to rotate. In order to be used on flat ground, this utility model also includes a secondary bridge plate 4 and a pull-out bracket 5. A support frame 21 is connected to the rear of the bottom support 1, and a support rod 6 passes through the support frame 21. A support block 61 is slidably connected to the support rod 6. The support block 61 includes an inclined surface for supporting the secondary bridge plate 4, that is, the upper end of the secondary bridge plate 4 rests on the support block 61, and the lower end rests on the ground. The secondary bridge plate 4 is provided with a through hole 41. The pull-out bracket 5 includes an insert 7 for inserting into the through hole 41 to prevent the secondary bridge plate 4 from sliding.

[0022] The usage of this utility model is as follows: This utility model is equipped with a secondary bridge plate 4 to help a car climb onto the rear of the main bridge plate 2 from a flat ground. When this utility model is used on a platform 8, the pull-out bracket 5 and the secondary bridge plate 4 are disassembled. When this utility model is used on a flat ground, the pull-out bracket 5 and the secondary bridge plate 4 are installed.
