[0034] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.
[0035] Example 1
[0036] As shown Figures 1 to 6 in the figure, this embodiment discloses a specific implementation manner of a scissor lift applicable to an ultra-low chassis.
[0037] The scissor lift applicable to an ultra-low chassis, as shown Figures 1 to 6 in the figure, includes two sets of scissor lift platforms 1 arranged in parallel; both ends of the scissor lift platform 1 are respectively provided with a first approach bridge assembly 2 and a second approach bridge assembly 3; the first approach bridge assembly 2 includes a first horizontal support plate 21 and a first approach bridge 22, a first L-shaped defect part 23 is arranged at the end of the first horizontal support plate 21, the first L-shaped defect part 23 is a rectangular defect dug down by a certain depth, and the first approach bridge 22 is placed on the first L-shaped defect part 23 or the first horizontal support plate 21; the second approach bridge assembly 3 includes a second horizontal support plate 31 and a second approach bridge 32, a second L-shaped defect part 33 is arranged at the end of the second horizontal support plate 31, the second L-shaped defect part 33 is a rectangular defect dug down by a certain depth, and the second approach bridge 32 is placed on the second L-shaped defect part 33 or the second horizontal support plate 31.
[0038] Specifically, referring to Figure 1 and Figure 2 , when the scissor lift platform 1 is at the lowest position (lowered to the lowest point), the lowest height of the scissor lift platform 1 is 120 mm - 135 mm, and the lowest height of the scissor lift platform 1 is preferably 135 mm; the heights of both the first horizontal support plate 21 and the second horizontal support plate 31 are 40 mm - 45 mm, preferably 45 mm; the depths of both the first L-shaped defect part 23 and the second L-shaped defect part 33 are 15 mm - 20 mm, preferably 20 mm; when the scissor lift platform 1 is at the lowest position, when the first approach bridge 22 is placed on the first L-shaped defect part 23 and the second approach bridge 32 is placed on the second L-shaped defect part 33, the vehicle front wheels drive in from the first horizontal support plate 21. Since the first horizontal support plate 21 provides a lower step for the vehicle front wheels to drive in, and the first approach bridge 22 is placed on the first L-shaped defect part 23 with a smaller downward swing angle, and the second approach bridge 32 is placed on the second L-shaped defect part 33 with a smaller downward swing angle, the vehicle front wheels can drive into the scissor lift platform 1 through a relatively gentle step and the first approach bridge 22, and drive out of the scissor lift platform 1 through a relatively gentle step and the second approach bridge 32. Finally, the vehicle front wheels stop on the second horizontal support plate 31, and the rear wheels stop on the first horizontal support plate 21. Through the above design, the scissor lift platform 1 can allow a vehicle with a chassis height ≥ 120 mm to drive in smoothly and straddle the scissor lift platform.
[0039] Referring to Figure 3Both the first horizontal support plate 21 and the second horizontal support plate 31 are installed on the ground. The length of the first horizontal support plate 21 is less than the length of the second horizontal support plate 31, so that the front wheels of the vehicle stop on the second horizontal support plate 31 and the rear wheels stop on the first horizontal support plate 21. The ends of the first horizontal support plate 21 and the second horizontal support plate 31 are respectively provided with slopes, which facilitates smooth vehicle travel. The second end 12 of the scissor lift platform is provided with a pull-out part 4, and the second approach bridge 32 is installed at the end of the pull-out part 4. When the vehicle straddles the scissor lift platform 1, in order to make the scissor lift platform 1 suitable for vehicles with longer wheelbases, the pull-out part 4 is pulled out to lengthen the scissor lift platform 1 and the second approach bridge 32 is raised, and the second approach bridge 32 rests on the second horizontal support plate 31.
[0040] See Figures 1 to 6 , Figure 5 The scissor lift platform 1 was raised to its highest position. The first approach bridge 22 includes a first approach bridge plate 221, a first rotating shaft 222, a first support arm 223, and a first support block 224. The first support block 224 is installed at the first end 11 of the scissor lift platform, and the first approach bridge plate 221 is installed at the first end 11 of the scissor lift platform via the first rotating shaft 222. The first support block 224 is provided with a first limiting groove 2241 and a second limiting groove 2242, which are located at different heights. One end of the first support arm 223 is rotatably disposed at the end of the first approach bridge plate 221, and the other end of the first support arm 223 is limited to the first limiting groove 2241 or the second limiting groove 2242. When the first support arm 223 is limited to the first limiting groove 2241, the first approach bridge plate 221 rests on the first L-shaped defect 23. When the first support arm 223 is limited to the second limiting groove 2242, the first approach bridge plate 221 rests on the first horizontal support plate 21. The second approach bridge 32 includes a second approach bridge plate 321, a second rotating shaft 322, a second support arm 323, and a second support block 324; the second support block 324 is installed at the second end 12 of the scissor lift platform, and the second approach bridge plate 321 is installed at the second end 12 of the scissor lift platform via the second rotating shaft 322; the second support block 324 is provided with a third limiting groove 3241 and a fourth limiting groove 3242, the third limiting groove 3241 and the fourth limiting groove 3242... Located at different heights, one end of the second support arm 323 is rotatably disposed at the end of the second approach plate 321, and the other end of the second support arm 323 is limited to the third limiting groove 3241 or the fourth limiting groove 3242; when the second support arm 323 is limited to the third limiting groove 3241, the second approach plate 321 rests on the second L-shaped defect 33; when the second support arm 323 is limited to the fourth limiting groove 3242, the second approach plate 321 rests on the second horizontal support plate 31.
