Seismic reduction and isolation technology is an effective method of earthquake disaster reduction. It absorbs and disperses the energy generated by the earthquake by introducing a shock-absorbing device between the foundation of the building and the target structure, thereby reducing the earthquake shock and vibration of the building. However, general vibration reduction and isolation devices can only absorb energy generated by vibrations in one direction, for example, they can only absorb vibrations in the horizontal or vertical direction. However, when an earthquake occurs in a general suspension structure, in addition to horizontal vibrations, it will also produce vertical vibrations, making it difficult for traditional shock-absorbing devices that can only absorb vibrations in one direction to fully protect the suspension structure.

Existing technical solutions for shock absorption and isolation of suspended structures often use vertical damping devices for shock absorption. This method can only dissipate energy in the vertical direction and has no obvious effect on the horizontal response of the structure. For suspended structures in high-altitude and high-seismic areas (such as suspended converter valves and DC filter equipment in converter stations), if horizontal shock absorption measures are not taken, the bottom of the suspended structure will be damaged under the action of earthquakes. Large horizontal displacements are produced, which in turn leads to traction damage or other secondary damage to adjacent equipment. Therefore, three-dimensional earthquake reduction and isolation technical solutions for suspended structures have great engineering implementation significance.

Based on this, an embodiment of the present application provides a shock-absorbing mechanism for isolating suspended structures (such as suspended converter valves and DC filter equipment in converter stations) in high-altitude and high-seismic areas. Shock and shock absorption protection. Specifically, referring to FIGS. 1 and 2 , a shock absorbing mechanism according to an embodiment includes a base 10 , a damping assembly 20 , a moving part 30 , a hanging part 50 and a transmission part 40 . The base 10 is used to be fixed to a fixed structure such as a hanger or a rack or the top of a building. The damping component 20 is used to absorb and disperse vibration energy, and the damping component 20 is arranged on the base 10 . The moving member 30 is connected to the damping assembly 20 , and the moving member 30 can move back and forth in the first direction relative to the base 10 . The hoisting component 50 is used to hoist the suspension structure. The hoisting component 50 can move back and forth relative to the base 10 along a second direction, where the second direction intersects the first direction. One end of the transmission member 40 is rotationally connected to the moving member 30 , and the other end of the transmission member 40 is rotationally connected to the lifting member 50 . The transmission member 40 is used to drive the moving member 30 along the first direction when the lifting member 50 reciprocates in the second direction. move.

Preferably, referring to Figure 2, in this embodiment, the first direction and the second direction are arranged perpendicularly. For example, the first direction is the horizontal direction and the second direction is the vertical direction. That is, the moving member 30 can move horizontally, and the lifting member 30 can move horizontally. 50 can move vertically.

When the above-mentioned shock-absorbing mechanism is in use, the base 10 can be fixed on a hanger or a rack or a structure such as the top of a building. The suspension structure is hoisted below the shock-absorbing mechanism through the hoisting piece 50. The suspension structure includes but is not limited to heavy objects, electrical equipment or building structures, etc. When an earthquake occurs or an external load is applied, causing the suspension structure to vibrate in the first direction (such as the horizontal direction) and the second direction (such as the vertical direction), the vibration of the suspension structure in the horizontal direction will drive the moving member 30 along the horizontal direction. The vibration energy in the horizontal direction is directly transferred to the damping component 20 , and the vibration energy is absorbed and dispersed by the damping component 20 , thereby achieving the purpose of shock absorption and isolation in the horizontal direction. The vibration energy of the suspension structure in the vertical direction is transmitted to the moving part 30 through the transmission part 40 and converted into movement of the moving part 30 in the horizontal direction, thereby converting the vibration energy in the vertical direction into vibration energy in the horizontal direction. , and the vibration energy is absorbed and dispersed by the damping component 20, thereby achieving the purpose of shock absorption and isolation in the vertical direction, so that the suspension structure can be fully protected against shock absorption and isolation in the three-dimensional space.

Referring to Figure 3, there are multiple damping components 20. Each damping component 20 is spaced apart in the circumferential direction with the lifting component 50 as the center. Each damping component 20 is connected to a moving part 30, and each moving part 30 is connected to a transmission. Part 40, all transmission parts 40 are connected to the lifting part 50. Multiple damping components 20 arranged at intervals along the circumferential direction can provide all-round protection for the suspension structure. No matter which direction the suspension structure vibrates on the horizontal plane, the damping components in the corresponding direction 20 can absorb and disperse vibration energy, improving the shock absorption and isolation effect. When the suspension structure vibrates in the vertical direction, each transmission member 40 can evenly disperse the vibration energy in the vertical direction to each damping component 20, thus also improving the shock absorption and isolation effects.

Referring to Figures 2 and 4, optionally, in a real-time example, each damping assembly 20 includes a piston cylinder 21, a piston member 223 and a damping member, wherein the piston cylinder 21 is fixed to the base 10, for example, the piston cylinder 21 can pass through It is fixed on the base 10 by screw connection, welding or bonding. The piston member 223 is movably disposed in the piston cylinder 21 , and is connected to the moving member 30 . The damping member is arranged in the piston cylinder 21 and connected to the piston member 223, so that when the suspension structure vibrates to drive the moving member 30 to reciprocate in the horizontal direction, it can drive the piston member 223 to reciprocate in the piston cylinder 21, and the damping member can hinder the piston. The reciprocating movement of the member 223 absorbs and disperses the vibration energy.

Further, continuing to refer to FIG. 4 , in this embodiment, the damping member includes a first elastic member 221 and a second elastic member 222 . One end of the first elastic member 221 is in contact with one side of the piston member 223 . The other end of the second elastic member 221 is in contact with the inner wall of one end of the piston cylinder 21; . When the suspension structure vibrates and drives the moving member 30 to reciprocate in the horizontal direction, it can drive the piston member 223 to reciprocate in the piston cylinder 21 , so that the piston member 223 continuously squeezes or stretches the first elastic member 221 and the second elastic member 221 . The elastic member 222 converts the vibration energy into the elastic potential energy of the first elastic member 221 and the second elastic member 222, and finally absorbs it in the form of friction between the piston member 223 and the piston cylinder 21, thereby absorbing and dispersing the vibration energy.

It is worth mentioning that in other embodiments, the damping member can also be hydraulic oil. The hydraulic oil is filled in the piston cylinder 21. When the suspension structure vibrates and drives the moving member 30 to reciprocate in the horizontal direction, it can drive the piston member 223 in the horizontal direction. The piston cylinder 21 moves back and forth, and the hydraulic oil exerts a damping effect on the piston member 223, thereby absorbing and dispersing vibration energy.

Referring to Figure 3, the base 10 is provided with an accommodation cavity 11. The accommodation cavity 11 has an opening penetrating one side of the base 10. The damping component 20 and the moving member 30 are both arranged in the accommodation cavity 11, and the lifting member 50 is arranged outside the opening. . By arranging the damping component 20 and the moving member 30 in the accommodation cavity 11, the overall structure of the damping mechanism is more reasonable and compact, saving space. By making the accommodation cavity 11 have an opening penetrating one side of the base 10 and arranging the hoisting part 50 outside the opening, it is convenient for the hoisting part 50 to hoist the suspension structure, and it is ensured that the hoisting part 50 follows the suspension structure to reciprocate in the vertical direction. will not interfere with the base 10.

For example, in this embodiment, the accommodating cavity 11 is a hexagonal cavity, the number of damping assemblies 20 is six, and the six damping assemblies 20 are arranged on the six inner walls of the accommodating cavity 11 in one-to-one correspondence.

Referring to Figure 5, optionally, in one embodiment, a mounting hole 12 is provided on the side of the base 10 away from the opening.

The mounting hole 12 is used to pass through the connector. , the connecting piece is used to fix the base 10. Specifically, the connecting member may be a bolt, through which the base 10 can be more conveniently fixed to the hanger or rack or the top of the building. Preferably, there are multiple mounting holes 12 , and the multiple mounting holes 12 are spaced apart on the side of the base 10 away from the opening, thereby improving the installation stability of the base 10 . It is worth noting that in other embodiments, the base 10 can also be fixed to the hanger or the rack or the top of the building through welding or bonding or integral molding, thereby eliminating the need to open the mounting holes 12 on the base 10 .

Referring to FIG. 6 , in one embodiment, the transmission member 40 includes a connecting rod, one end of the connecting rod is rotationally connected to the moving member 30 , and the other end of the connecting rod is rotationally connected to the lifting member 50 .
