DETAILED DESCRIPTION

[0024] In order to make the person skilled in the art better understand the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in the following description of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all.

[0025] EMBODIMENT

[0026] As Figure 1 shown in the drawings, the embodiment discloses a steel column anti-seismic base, which comprises a bottom plate 1, a steel column mounting seat 4 swingably arranged on the bottom plate 1, and a damping mechanism 6 movably connected at one end to the steel column mounting seat 4 and at the other end to the bottom plate 1. In use, the bottom plate 1 is anchored to the slope by anchor rods, so that the entire steel column anti-seismic base is installed on the slope.

[0027] Specifically, as Figure 5 shown in the drawings, the damping mechanism comprises a second damping column 65 movably connected at the lower end to the bottom plate 1 and provided at the upper end with a damping sleeve 63, a spring 64 arranged in the damping sleeve 63, and a first damping column 61 movably connected at the upper end to the steel column mounting seat 4 and inserted at the lower end into the damping sleeve 63.

[0028] In arrangement, the lower end of the first damping column 61 is provided with a pressing plate 62, and the spring 64 is located between the pressing plate 62 and the bottom of the damping sleeve 63. When the first damping column 61 is subjected to pressure, it will compress the spring 64, thereby buffering the pressure it receives.

[0029] The damping mechanism can be installed in the following manner to enable it to swing, i.e. two mounting plates are oppositely arranged on the bottom plate 1, and the lower end of the second damping column 65 is provided with a pin hole. In installation, the lower end of the second damping column 65 is located between the two mounting plates, and then a pin shaft is passed through the pin holes on the two mounting plates and the pin hole on the second damping column 65, thereby connecting the second damping column 65 to the bottom plate 1. The pin shaft and the pin hole on the second damping column 65 are in clearance fit, so the second damping column 65 can swing about the pin shaft as a fulcrum. Correspondingly, the upper end of the first damping column 61 is also swingably connected to the steel column mounting seat 4 by the above-mentioned installation manner, and the lower end of the steel column mounting seat 4 is also swingably installed on the bottom plate 1 by the above-mentioned installation manner.

[0030] The diameter of the pressing plate 62 matches the inner diameter of the damping sleeve 63, so that the pressing plate 62 can be installed in the damping sleeve 63. The upper end of the damping sleeve 63 can be provided with an end cover, which is threadedly connected with the damping sleeve 63, so that the end cover and the damping sleeve 63 can be disassembled, facilitating the installation of the spring 64 and the lower end of the first damping column 61 in the damping sleeve 63. In installation, after the spring 64 and the lower end of the first damping column 61 are installed in the damping sleeve 63, the end cover is covered, and finally the upper end of the first damping column 61 is connected to the steel column mounting seat 4.

[0031] In use, the steel column 8 is installed on the steel column mounting seat 4. When a stone falls on the protective net, the impact force is applied to the steel column 8, the steel column 8 applies pressure to the steel column mounting seat 4, the steel column mounting seat 4 swings, and the impact force received by the steel column 8 is absorbed by compressing the damping mechanism 6, thereby protecting the steel column 8.

[0032] As a mounting mode, as shown in Figure 2 , the steel column mounting seat 4 is provided with a T-shaped notch 7, since the steel column 8 is an I-beam or H-shaped steel, when mounting, one side of the steel column 8 is inserted into the T-shaped notch 7 from the end of the steel column mounting seat 4, so as to mount the steel column 8 on the steel column mounting seat 4, as shown in Figure 3 , 4 .

[0033] As another mounting mode, the steel column 8 can also be mounted on the steel column mounting seat 4 by bolts. Specifically, a waist-shaped hole is provided on the flange plate of the steel column 8, and the bolt is connected to the steel column mounting seat 4 after passing through the waist-shaped hole. By providing the waist-shaped hole, a certain amount of movement can be provided between the steel column mounting seat 4 and the steel column.

[0034] As shown in Figure 1 , the lower end of the steel column mounting seat 4 is connected with a support plate 2, so as to support the steel column 8. In addition, a rubber buffer pad 3 is provided on the support surface of the support plate 2, which can buffer the axial impact force received by the steel column 8, further protecting the steel column 8.

[0035] As another optional implementation, the steel column mounting seat 4 and the bottom plate 1 are further provided with a connecting rod suspension 5, and the two ends of the connecting rod suspension 5 can also be mounted between the steel column mounting seat and the bottom plate in the same mounting mode as the damping mechanism 6 described above, and can be swingably mounted. The connecting rod suspension 5 is composed of two connecting rods, which are swingably connected through a pin shaft, and a torsional spring is sleeved on the pin shaft. When the steel column mounting seat 4 is subjected to pressure, the connecting rod suspension 5 is also compressed, thereby further buffering the pressure received by the steel column mounting seat 4.

[0036] It should be noted that all the features disclosed in the specification, or the steps in all the methods or processes disclosed, can be combined in any manner, except for mutually exclusive features and / or steps.

[0037] In addition, the above specific embodiments are exemplary, and those skilled in the art can think of various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed scope of the present application and fall within the protection scope of the present application. Those skilled in the art should understand that the specification and drawings of the present application are illustrative and do not constitute a limitation on the claims. The protection scope of the present application is defined by the claims and their equivalents.
