Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic dampers, in particular to a hydraulic damper based on a stay cable. Background Art

[0002] The hydraulic damper based on the cable is a vibration reduction device used to control the vibration of the cable. It uses hydraulic technology to absorb and dissipate the energy generated by the cable under wind vibration, traffic load or other dynamic effects. The hydraulic damper is usually installed at a specific position of the cable, such as near the anchor end or the middle of the cable body, to improve the damping ratio of the structure, reduce vibration, and thus improve the stability and safety of the bridge;

[0003] In practical applications, hydraulic dampers can significantly reduce wind-induced vibrations of the cable, improve the comfort and safety of the structure, and extend its service life. The design and installation of hydraulic dampers need to take into account the specific conditions of the cable, including the length, tension, material properties, and wind speed and direction of the environment.

[0004] After long-term use, the hydraulic damper rod installed inside the hydraulic damper will age and need to be replaced. During the later replacement process, if the weather is windy, the cable-stayed cable will shake, making it inconvenient to replace. Therefore, a hydraulic damper based on the cable-stayed cable is proposed to address the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a hydraulic damper based on a cable-stayed cable to solve the problem that after the hydraulic damper is used for a long time, the hydraulic damping rod arranged inside the hydraulic damper will age and need to be replaced. During the later replacement process, if the weather is windy and strong, the cable-stayed cable will shake, which will make it inconvenient to replace.

[0007] A hydraulic damper based on an inclined cable comprises a hydraulic damping rod and a connecting clamp, wherein the top end of the hydraulic damping rod is connected to the connecting clamp used for connecting to the inclined cable through a connecting piece, and the bottom end of the hydraulic damping rod is connected to a connecting plate through a connecting piece, a first through hole and a second through hole are provided in the middle of the upper end of the connecting plate, a cap is installed on the inner side of the upper end of the second through hole, a sleeve is installed on the inner side of the first through hole, a connecting mechanism is provided inside the sleeve, and a bottom fixing mechanism is installed on the lower end of the connecting plate; the bottom fixing mechanism comprises a fixed base, a circular groove is provided on the inner side of the upper end of the fixed base, a threaded hole is provided on the inner side of the bottom end of the circular groove, and a fixing block and a limiting column are fixedly connected to the side surface of the fixed base in sequence from top to bottom; the connecting mechanism comprises a bolt, and a sealing ring is fixedly connected to one end of the bolt.

[0008] As a further optimization of the present invention, the fixed base is T-shaped, a through hole is provided inside the fixed block, and an annular groove is provided in the middle of the limiting column.

[0009] As a further optimization of the present invention, two of each of the second through hole, the fixing block and the limiting column are provided, and the center points of the second through hole, the fixing block and the limiting column provided on a single side are provided on the same vertical line.

[0010] As a further optimization of the present invention, the connecting mechanism, the first through hole and the sleeve are each provided with two, the first through hole and the sleeve are coaxial, the sleeve is T-shaped, the bottom end of the sleeve is exposed outside the lower end of the first through hole, and the edge of the bottom end of the sleeve is arc-shaped.

[0011] As a further optimization of the present invention, the bolt is spirally connected to the fixed base via a threaded hole, the bottom end of the sleeve is installed inside a circular groove opened at the upper end of the fixed base, and the upper end of the bolt is tightly attached to the connecting plate via a sealing ring.

[0012] As a further optimization of the present invention, there are two hydraulic damping rods, the angle between the hydraulic damping rods and the connecting plate is 75°, and the hydraulic damping rods are symmetrically arranged with a vertical line formed by the center point of the connecting clamp and the center point of the connecting plate.

[0013] As a further optimization of the present invention, there are four connecting members, the connecting members are fixedly connected to the connecting clamps and the connecting plates, and the connecting members are rotationally connected to the hydraulic damping rods.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, by providing the bottom fixing mechanism, the connecting plate and the second through hole, during the installation process, a rope can be passed through the connecting plate and the fixing mechanism, and then the deformation of the hydraulic damping rod can be used for stable limiting, thereby preventing the inclined cable from shaking during the installation process, which would cause the hydraulic damping rod to be difficult to fix on the upper end of the fixed base after replacement, thereby improving the convenience of later replacement of the hydraulic damping rod.

[0029] As a further implementation of this solution, the fixed base 11 is T-shaped, a through hole is provided inside the fixed block 14, and a ring groove is provided in the middle of the limiting column 12. Through the above arrangement, it is convenient to position the connection plate 2 and the fixed base 11 later;

[0030] As a further implementation of the present invention, two second through holes 7, two fixing blocks 14 and two limiting columns 12 are provided, and the center points of the second through holes 7, the fixing blocks 14 and the limiting columns 12 provided on one side are provided on the same vertical line. Two connecting mechanisms 5, two first through holes 6 and two sleeves 9 are provided, and the first through holes 6 and the sleeves 9 have the same axis. The sleeves 9 are T-shaped, and the bottom end of the sleeves 9 is exposed outside the lower end of the first through holes 6, and the bottom edge of the sleeves 9 is arc-shaped. Through the above arrangement, the stability of the device as a whole during later use can be improved;

[0031] As a further implementation of this solution, the bolt 51 is spirally connected to the fixed base 11 through the threaded hole 15, the bottom end of the sleeve 9 is installed in the circular groove 13 opened at the upper end of the fixed base 11, and the upper end of the bolt 51 is tightly attached to the connecting plate 2 through the sealing ring 52. Through the above arrangement, the connecting plate 2 and the fixed base 11 can be stably connected together;

[0032] As a further implementation of the present invention, two hydraulic damping rods 3 are provided, the angle between the hydraulic damping rods 3 and the connecting plate 2 is 75°, and the hydraulic damping rods 3 are symmetrically arranged with the vertical line formed by the center point of the connecting clamp 4 and the center point of the connecting plate 2.
