Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] In order to solve the problem that in the actual use process of the existing bridge support structure, the structural position stability cannot be guaranteed, and under long-term work, it will shake under pressure, resulting in the position deviation of the steel components, please refer to Figure 1 - Figure 2 This embodiment provides the following technical solutions:

[0022] A stable support structure for bridge steel components, including a bridge steel frame 1, a positioning bracket 2, and a support pressing plate 3. The positioning bracket 2 is arranged at the upper and lower ends of the bridge steel frame 1, the support pressing plate 3 is installed in the middle of the bridge steel frame 1, and a limiting rod 203 and a hydraulic damping rod 303 are installed between the support pressing plate 3 and the positioning bracket 2. A movable sleeve 204 is installed between the hydraulic damping rod 303 and the limiting rod 203. By installing the support pressing plate 3 in the middle position of the positioning bracket 2 for buffering, the position strength of the bridge steel frame 1 is improved to adapt to long-term work.

[0023] Furthermore, the positioning bracket 2 is connected to the bridge steel frame 1 through fixing bolts. An integrally formed positioning hole 201 is arranged on the outside of the positioning bracket 2. The positioning hole 201 is used to fix the bridge support plate and the support base. During the installation of the support structure, by fixing two groups of positioning brackets 2 above and below the bridge steel frame 1 respectively, and fixing the positioning brackets 2 to the bridge support plate and the base, the position of the positioning brackets 2 is kept fixed.

[0024] Further, connecting rollers 202 are installed on both sides of the positioning bracket 2. One end of the limiting rod 203 extends into the interior of the connecting roller 202 and is fixedly connected to the connecting roller 202. The connecting roller 202 is rotatably connected to the positioning bracket 2 through a bearing. The lower end of the limiting rod 203 extends into the interior of the movable sleeve 204 and is fixedly connected to the movable sleeve 204. The upper end of the hydraulic damper rod 303 is rotatably connected to the movable sleeve 204 through a bearing. A connecting ear 304 is installed at the lower end of the hydraulic damper rod 303, and the hydraulic damper rod 303 is rotatably connected to the supporting pressing plate 3 through the connecting ear 304. The supporting pressing plate 3 and the connecting ear 304 are connected by welding. The hydraulic damper rod 303 presses the limiting rod 203, so that both sides of the supporting pressing plate 3 are squeezed and pushed, maintaining a stable position. Thus, both sides of the bridge steel frame 1 are restricted. During long-term operation, even if the bridge steel frame 1 is subjected to pressure, the hydraulic damper rod 303 cooperates with the supporting pressing plate 3 to buffer, improving the position strength of the bridge steel frame 1 and adapting to long-term operation.

[0025] Specifically, during the installation of the supporting structure, by fixing two groups of positioning brackets 2 above and below the bridge steel frame 1 respectively, and fixing the positioning brackets 2 to the bridge support plate and the base, after keeping the position of the positioning brackets 2 fixed, by installing the supporting pressing plate 3 at the middle position of the positioning brackets 2, the hydraulic damper rod 303 presses the limiting rod 203, so that both sides of the supporting pressing plate 3 are squeezed and pushed, maintaining a stable position. Thus, both sides of the bridge steel frame 1 are restricted. During long-term operation, even if the bridge steel frame 1 is subjected to pressure, the hydraulic damper rod 303 cooperates with the supporting pressing plate 3 to buffer, improving the position strength of the bridge steel frame 1 and adapting to long-term operation.

[0026] In order to solve the problem that in the actual use process of the existing bridge supporting structure, it is difficult to keep the position of the supporting structure stable, and it is easy to shake after being impacted, please refer to Figure 1 - Figure 4 This embodiment provides the following technical solutions:

[0027] Movable openings 307 are integrally formed on both sides of the supporting pressing plate 3, and telescopic plates 301 are installed at the front end and the rear end of the supporting pressing plate 3. The telescopic plates 301 extend into the interior of the supporting pressing plate 3 and are slidably connected to the supporting pressing plate 3. A damping spring 309 is installed inside the supporting pressing plate 3. Both ends of the damping spring 309 are welded to the telescopic plate 301 and the supporting pressing plate 3 respectively. Through the supporting pressing plate 3 and the damping spring 309, the supporting pressing plate 3 is fully attached to the bridge steel frame 1. When the bridge steel frame 1 is impacted, the supporting pressing plate 3 can still provide a certain auxiliary supporting force, maintaining the strength of the bridge structure and improving the supporting effect.

[0028] Furthermore, connection brackets 302 are installed on both sides outside the support pressing plate 3. A fastening sleeve 305 is installed between the two connection brackets 302. A threaded rod 306 passes through the inside of the fastening sleeve 305. The threaded rod 306 is rotatably connected to the fastening sleeve 305 through a bushing. A thread hole 308 formed integrally is provided inside the connection bracket 302. The threaded rod 306 passes through the thread hole 308 and is threadedly connected to the connection bracket 302. The threaded rod 306 is fixedly connected to the connection bracket 302 through a bolt. By adjusting the threaded rod 306, the connection brackets 302 at both ends are driven to move and press against the bridge steel frame 1 to adapt to bridge steel frames 1 of different widths.

[0029] Specifically, by adjusting the threaded rod 306, the connection brackets 302 at both ends are driven to move and press against the bridge steel frame 1 to adapt to bridge steel frames 1 of different widths. Moreover, through the support pressing plate 3 and the damping spring 309, the support pressing plate 3 can fully fit the bridge steel frame 1. When the bridge steel frame 1 is impacted, the support pressing plate 3 can still provide a certain amount of auxiliary support force to maintain the strength of the bridge structure and improve the effect of the support work.

[0030] Working principle: During the installation process, by fixing the two groups of positioning brackets 2 above and below the bridge steel frame 1 respectively, and fixing the positioning brackets 2 to the bridge support plate and the base, after keeping the positions of the positioning brackets 2 fixed, the support pressing plate 3 is installed at the middle position of the positioning brackets 2. By adjusting the threaded rod 306, the connection brackets 302 at both ends are driven to move and press against the bridge steel frame 1 to adapt to bridge steel frames 1 of different widths. Moreover, through the support pressing plate 3 and the damping spring 309, the support pressing plate 3 can fully fit the bridge steel frame 1. When the bridge steel frame 1 is impacted, the support pressing plate 3 can still provide a certain amount of auxiliary support force to maintain the strength of the bridge structure and improve the effect of the support work. The hydraulic damping rod 303 presses the limit rod 203, so that both sides of the support pressing plate 3 are squeezed and pushed to keep the position stable, thereby restricting both sides of the bridge steel frame 1. During long-term operation, even if the bridge steel frame 1 is under pressure, through the cooperation of the hydraulic damping rod 303 and the support pressing plate 3 for buffering, the position strength of the bridge steel frame 1 is improved to adapt to long-term operation.
