Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0032] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0033] like Figure 1 As shown, at least one embodiment provides a trestle platform, including: a bridge deck 1 and a support assembly 2. One end of the bridge deck 1 is erected on the embankment 11, and the other end is raised and lowered by the telescopic movement of the support assembly 2, thereby resting on the hull 12.
[0034] like Figure 2 As shown, in some embodiments, the support assembly 2 includes: a first hydraulic cylinder 21 and a second hydraulic cylinder 22. The two ends of the first hydraulic cylinder 21 are respectively hinged to the support base 20 and the bridge plate 1, and the two ends of the second hydraulic cylinder 22 are also respectively hinged to the support base 20 and the bridge plate 1. The first hydraulic cylinder 21 is hinged to the bridge plate 1 through the first hinge hole 210, and the second hydraulic cylinder 22 is hinged to the bridge plate 1 through the second hinge hole 220.
[0035] In related technologies, when a vehicle travels on the bridge plate 1, one side of the bridge plate 1 is subjected to force, and the other side tends to lift up, resulting in a large impact load on the first hinge hole 210 and the second hinge hole 220.
[0036] To address the aforementioned issues, in some embodiments, the first hinge hole 210 is configured as an oblong hole, and the second hinge hole 220 is configured as a circular hole.
[0037] In this embodiment, when the vehicle is driving on the bridge plate 1, one side of the bridge plate 1 is subjected to force, and the other side tends to tilt. At this time, since the first hinge hole 210 is an oblong hole, the tilting of the bridge plate 1 will not be restricted, thereby reducing the impact load on the hinge hole.
[0038] like Figure 3 , Figure 4 As shown, in some embodiments, both the first cylinder 21 and the second cylinder 22 include: a cylinder body 211 and a piston rod 212; wherein the outer end of the piston rod 212 is a rod head 213; a first hinge hole 210 is provided on the rod head 213 of the first cylinder 21; and a second hinge hole 220 is provided on the rod head 213 of the second cylinder 22.
[0039] In some embodiments, a spherical bearing 214 is provided in both the first hinge hole 210 and the second hinge hole 220; the first hydraulic cylinder 21 is hinged to the bridge plate 1 through the spherical bearing 214 in the first hinge hole 210; the second hydraulic cylinder 22 is hinged to the bridge plate 1 through the spherical bearing 214 in the second hinge hole 220.
[0040] In this embodiment, such as Figure 5 , Figure 6 As shown, the hydraulic cylinder is hinged to the bridge plate 1 via a spherical bearing 214. When the bridge plate 1 is tilted up, the spherical bearing 214 in the first hinge hole 210 will rise or fall within the first hinge hole 210, thereby reducing the impact load on the spherical bearing 214.
[0041] In some embodiments, cover plates 215 are provided on both sides of the rod head 213 of the first hydraulic cylinder 21.
[0042] In this embodiment, the cover plate 215 can provide protection when the spherical bearing 214 moves.
[0043] In some embodiments, both the first cylinder 21 and the second cylinder 22 further include: a cylinder bottom 216; the cylinder bottom 216 of the first cylinder 21 is provided with a third hinge hole 217; the cylinder bottom 216 of the second cylinder 22 is provided with a fourth hinge hole 221; the first cylinder 21 is hinged to the support base 20 through the third hinge hole 217; the second cylinder 22 is hinged to the support base 20 through the fourth hinge hole 221; wherein, the third hinge hole 217 is a circular hole, and the fourth hinge hole 221 is a circular hole.
[0044] In some embodiments, a spherical bearing 214 is provided in both the third hinge hole 217 and the fourth hinge hole 221.
[0045] In this embodiment, of the four hinge holes of the first hydraulic cylinder 21 and the second hydraulic cylinder 22, only the first hinge hole 210 is set as an oblong hole, while the rest are round holes. This makes the bridge plate 1 form a "seesaw" structure, thereby reducing the impact load on the hinge by rotating when subjected to force on one side.
[0046] like Figure 1 As shown, at least one embodiment also includes a trestle platform system, comprising: a embankment 11, a hull 12, a bridge deck 1, a support base 20, and a support assembly 2; one end of the bridge deck 1 is erected on the embankment 11; the support assembly 2 includes: a first hydraulic cylinder 21 and a second hydraulic cylinder 22; wherein the first hydraulic cylinder 21 and the second hydraulic cylinder 22 are both mounted on the support base 20 and connected to the bridge deck 1, and are adapted to drive the other end of the bridge deck 1 to be erected on the hull 12 through telescopic movement.
[0047] In some embodiments, the first hydraulic cylinder 21 is hinged to the bridge plate 1 through the first hinge hole 210; the second hydraulic cylinder 22 is hinged to the bridge plate 1 through the second hinge hole 220; the first hinge hole 210 is an oblong hole, and the second hinge hole 220 is a circular hole; when the bridge plate 1 is subjected to force on one side, the bridge plate 1 is adapted to rotate around the second hinge hole 220 of the second hydraulic cylinder 22.
[0048] In some embodiments, the first cylinder 21 and the second cylinder 22 each include a cylinder body 211 and a piston rod 212; wherein the outer end of the piston rod 212 is a rod head 213; a first hinge hole 210 is provided on the rod head 213 of the first cylinder 21; and a second hinge hole 220 is provided on the rod head 213 of the second cylinder 22.
[0049] In some embodiments, a spherical bearing 214 is provided in both the first hinge hole 210 and the second hinge hole 220; the first hydraulic cylinder 21 is hinged to the bridge plate 1 through the spherical bearing 214 in the first hinge hole 210; the second hydraulic cylinder 22 is hinged to the bridge plate 1 through the spherical bearing 214 in the second hinge hole 220; wherein, when the bridge plate 1 is subjected to force on one side, the spherical bearing 214 in the first hinge hole 210 is adapted to rise or fall within the first hinge hole 210.
[0050] In summary, by setting the first hinge hole 210 of the first hydraulic cylinder 21 as an oblong hole and the second hinge hole 220 of the second hydraulic cylinder 22 as a circular hole, the bridge plate 1 forms a "seesaw" structure, thereby reducing the impact load on the hinge by rotating when subjected to force on one side.
