[0036] [First Embodiment]
[0037] like Figure 1-7 The image shown is a steel frame bridge support pier provided in the first embodiment of this utility model, as follows: Figure 1 and Figure 5 As shown, the bridge includes a pier body 1. Two symmetrical mounting plates 2 are detachably mounted on the arc surface of the pier body 1 via an auxiliary device 4, and the inner wall of the mounting plate 2 is in contact with the outer edge of the pier body 1. A protective device 3 is detachably mounted on the outer edge of the mounting plate 2. By detachably mounting the protective device on the outer edge of the mounting plate, the pier body is protected, providing a buffer against unexpected vehicle impacts, effectively ensuring the support stability of the pier and extending its service life.
[0038] like Figure 2-5 and Figure 7 As shown, the protective device 3 in this embodiment includes a plurality of fixing plates 31 that are uniformly fixedly connected to the outside of the mounting plate 2, and a protective plate 32 is detachably installed on the outside of the mounting plate 2 through the fixing plates 31.
[0039] Its detachable installation method is achieved through the following structure: The top of the fixing plate 31 is provided with a groove 34, and the insert plate 36 is slidably connected inside the groove 34. The bottom of the groove 34 and the insert plate 36 are fixedly connected with a telescopic rod 38 and an elastic element 35. The elastic element 35 is sleeved on the outer periphery of the telescopic rod 38. The inner wall of the protective plate 32 is provided with a fixing groove 33, and the fixing plate 31 can enter the fixing groove 33 and cooperate with it. The top of the fixing groove 33 is provided with an insertion hole 37, and the insert plate 36 can enter the insertion hole 37 and cooperate with it.
[0040] This setting makes:
[0041] When installing the protective plate 32, the protective plate 32 is moved so that the fixing groove 33 is aligned with the fixing plate 31. The inner wall of the protective plate 32 presses the insert plate 32, so that the insert plate 32 enters the groove 34 and at the same time, the elastic element 35 is deformed. When the insert plate 36 moves to the position of the insertion hole 37, under the action of the elastic restoring force of the elastic element 35, the insert plate 36 enters the insertion hole of the protective plate, so as to fix the protective plate 32 on the outside of the fixing plate 31.
[0042] When disassembling the protective plate 32, the protective plate 32 is moved and the protective plate 32 presses against the insert plate 36, causing the insert plate 36 to deform the elastic element 35 and move out of the insertion hole 37. Then the fixing groove 33 of the protective plate 32 is separated from the fixing plate 31, thereby realizing the disassembly of the protective plate 32.
[0043] To facilitate the extension and retraction of the insert plate 36 during the loading and unloading process, symmetrical ramps are provided on both sides of the top of the insert plate 36.
[0044] In this embodiment, the protective plate 32 is made of hollow plastic sheet, and foam is installed inside the protective plate 32. While protecting the pier body through the protective device, the internal foam can provide cushioning against unexpected vehicle impacts, effectively ensuring the support stability of the pier and extending its service life. Several reflective strips 39 are uniformly fixedly connected to the outside of the protective plate 32. The reflective strips 39 are linearly distributed. By setting reflective strips on the outside of the protective plate, reflective warnings can be provided to drivers at night, reducing the possibility of collisions with the pier at night.
[0045] like Figure 5-6 As shown, the auxiliary device 4 in this embodiment includes several positioning rods 41 fixedly connected to a mounting plate 2 on one side, and several positioning holes 42 opened on the mounting plate 2 on the other side. The positioning rods 41 can enter the positioning holes 42 and cooperate with them. A rubber ring 43 is fixed on the outer periphery of the positioning rods 41. A limiting groove 44 is opened inside the positioning hole 42. The rubber ring 43 can enter the limiting groove 44 and cooperate with it. By placing the positioning rods 41 into the positioning holes 42 and cooperating with them, and by the elastic contraction and deformation of the rubber ring 43 when the positioning rods 41 are placed into the positioning holes 42, and by the elastic restoring force after the rubber ring 43 enters the limiting groove 44, the stable positioning effect of the positioning rods 41 inside the positioning holes 42 is achieved.
[0046] To facilitate the insertion of the positioning rod 41 into the positioning hole 42, a pointed protrusion 45 is fixedly provided on the protruding end of the positioning rod 41.
[0047] The specific working process of this embodiment is as follows:
[0048] When installing the protective plate 32, the protective plate 32 is moved so that the fixing groove 33 is aligned with the fixing plate 31. The inner wall of the protective plate 32 presses the insert plate 32, so that the insert plate 32 enters the groove 34 and at the same time, the elastic element 35 is deformed. When the insert plate 36 moves to the position of the insertion hole 37, under the action of the elastic restoring force of the elastic element 35, the insert plate 36 enters the insertion hole of the protective plate, so as to fix the protective plate 32 on the outside of the fixing plate 31.
[0049] When disassembling the protective plate 32, the protective plate 32 is moved and the protective plate 32 presses against the insert plate 36, causing the insert plate 36 to deform the elastic element 35 and move out of the insertion hole 37. Then the fixing groove 33 of the protective plate 32 is separated from the fixing plate 31, thereby realizing the disassembly of the protective plate 32.
[0050] When installing the mounting plate 2, move the two mounting plates 2 to cover the pier body 1. The positioning rod 41 on one of the mounting plates 2 is slowly inserted into the positioning hole 42 of the other mounting plate 2 with the help of the pointed protrusion 45. During this process, the rubber ring 43 is squeezed and deformed by the inner wall of the positioning hole 42. When the rubber ring 43 moves into the limiting groove 44, the rubber ring 43 returns to its original shape under the action of its own elastic restoring force, thereby achieving the stable positioning effect of the positioning rod 41 inside the positioning hole 42.
[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
