[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2 The utility model provides an embodiment: a lateral seismic support for a bridge frame, including a frame body 1, the frame body 1 is the main body of the bridge frame, which is the existing technology and can carry cables. The outer wall of the bottom end of the frame body 1 is provided with a base 4 through an adjusting mechanism 2, the base 4 is the main body of the bridge frame support, and the frame body 1 can be installed. The base 4 can adapt to the frame body 1 with different threaded hole positions through the adjusting mechanism 2, and the adaptability is higher. The outer wall of the base 4 is provided with a buffer mechanism 3, and the buffer mechanism 3 can play a buffering effect when the frame body 1 is subjected to lateral vibration to avoid deformation or damage.

[0032] Reference Figure 3The adjusting mechanism 2 includes a threaded rod 201, the outer wall of which is rotatably connected to the inner wall of the base 4, and the threaded rod 201 can be rotated to adjust the position of the two sets of sliding plates 203. The outer wall of the threaded rod 201 is threadedly connected with a slider 206, and the slider 206 is annular. When the threaded rod 201 rotates, the slider 206 moves back and forth along the outer wall of the threaded rod 201 under the guiding effect. The outer wall of the slider 206 is fixedly connected with a connecting block 205, and the connecting block 205 is provided with two groups and symmetrically distributed on the outer walls of both sides of the slider 206. The outer wall of the connecting block 205 is hinged with a sliding plate 203 through a connecting rod 202. The sliding plate 203 is slidably connected to the inner wall of the base 4, so that the sliding plate 203 can only move laterally, thereby guiding the slider 206, so that when the threaded rod 201 rotates, the slider 206 cannot rotate therewith, and can only move back and forth along the outer wall of the threaded rod 201.

[0033] Reference Figure 3 The outer wall of the sliding plate 203 is provided with a through slot 204, and the sliding plate 203 is moved horizontally so that the through slot 204 can correspond to the threaded holes at different positions on the frame 1, so that frames 1 of different sizes and specifications can be installed, and the adaptability is higher.

[0034] Reference Figure 4 The buffer mechanism 3 includes a mounting seat 301. Two groups of mounting seats 301 are provided and symmetrically distributed on both sides of the base 4. The inner wall of the mounting seat 301 is slidably connected to the outer wall of the base 4. When subjected to lateral lateral vibration, the base 4 can move laterally on the inner wall of the mounting seat 301. The top outer wall of the mounting seat 301 is fixedly connected with a hanging rod 5. The top of the hanging rod 5 can be connected to the roof of the building to hang the frame 1. The bottom end of the hanging rod 5 is fixedly connected to the mounting seat 301 by a positioning bolt 6. The positioning bolt 6 can pass through the bottom end of the hanging rod 5 and be threadedly connected to the top inner wall of the mounting seat 301, thereby fixing the two.

[0035] Reference Figure 4The inner wall of the mounting seat 301 is fixedly connected with a buffer spring 305. Two groups of buffer springs are provided and symmetrically distributed in the inner wall of the mounting seat 301. The buffer spring 305 is fixedly connected to the outer wall of the base 4. When the base 4 moves laterally due to vibration, the buffer spring 305 on one side is squeezed to shrink, and the buffer spring 305 on the other side is stretched. The elastic force of the buffer spring 305 itself can play a certain buffering effect. The inner wall of the mounting seat 301 is fixedly connected with a fixing rod 302. The fixing rod 302 is cylindrical and fixedly connected to the inner wall of one side of the mounting seat 301.

[0036] Reference Figure 4 The outer wall of the fixed rod 302 is fixedly connected with a rubber ring 304, and multiple groups of rubber rings 304 are provided. The outer wall of the fixed rod 302 is slidably connected with a damping ring 303. The damping ring 303 is a prior art, and a rubber pad is provided on the inner wall. The inner wall of the damping ring 303 contacts the outer wall of the rubber ring 304. The contact between the damping ring 303 and the outer wall of the rubber ring 304 can increase friction, further improve the buffering effect, and reduce the impact of vibration on the frame 1. The outer wall of the damping ring 303 is hinged with a rotating rod 306, and the rotating rod 306 is hinged to the outer wall of the base 4. When the base 4 moves laterally, the rotating rod 306 is driven to flip, thereby driving the damping ring 303 to move on the outer wall of the fixed rod 302.

[0037] Working principle: the operator can first fix the hanger 5 on the roof through the positioning bolts 6, and then fix the bottom end of the hanger 5 to the mounting seat 301 through the positioning bolts 6 to complete the installation of the bridge bracket. Then, the adjustment mechanism 2 can be adjusted according to the position of the threaded hole of the frame body 1. At this time, the operator can rotate the threaded rod 201 to drive the slider 206 to move back and forth on the outer wall of the threaded rod 201, and drive the sliding plate 203 to move horizontally through the connecting rod 202. The two sets of sliding plates 203 move to the middle or both sides at the same time to adjust the horizontal position of the through groove 204. When the through groove 204 corresponds to the horizontal position of the threaded hole of the frame body 1, the frame body 1 can be placed above the sliding plate 203, and the frame body 1 and the sliding plate 203 can be fixed by the positioning bolts 6. After the fixing is completed, since the sliding plate 203 is in a fixed state, the connecting rod 202 and the threaded rod 201 are also kept in a fixed state, the installation of the frame body 1 can be completed, and it can be adjusted according to the position of the threaded hole on the frame body 1 to adapt to the frame body 1 with different threaded hole positions.

[0038] When the frame 1 moves laterally due to vibration, the base 4 moves synchronously therewith, and since the positions of the suspension rod 5 and the mounting base 301 are fixed, the base 4 moves laterally in the inner wall of the mounting base 301, causing the buffer spring 305 on one side to contract under force and the buffer spring 305 on the other side to stretch under force, thereby playing a certain buffering effect under the elastic force of the buffer spring 305, and during the movement of the base 4, the rotating rod 306 is forced to flip over, driving the damping ring 303 to move on the surface of the rubber ring 304 on the fixed rod 302, and since the friction between the damping ring 303 and the rubber ring 304 is too large, the buffering effect can be improved and the vibration amplitude of the base 4 can be reduced, thereby avoiding the problem of damage to the frame 1 caused by excessive vibration.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
