Multi-power hybrid shock absorber for buildings

Abstract

The invention discloses a multi-power hybrid shock absorber for buildings. The multi-power hybrid shock absorber includes a bottom supporting plate and a top supporting plate; electromagnetic hollow casings integrated with the bottom supporting plates are arranged on two opposite sides of an upper surface of the bottom supporting plate; an iron core is arranged on the bottom of each electromagnetic hollow casing, a side surface of the iron core is fixed in a coil, an electromagnetic hollow structure is positioned above the iron core in the electromagnetic hollow casing, a permanent magnet is arranged in the electromagnetic hollow structure, an electromagnetic movable plate is placed on an upper surface of the permanent magnet, and an electromagnetic pushing rod is fixed on the top of an upper surface of the movable plate. The multi-power hybrid shock absorber can integrate steel plate energy consumption, air flow and electromagnetic interaction so as to form a multi-power hybrid shockabsorption effect, can integrate the advantages of the three shock absorption manners, can reduce energy generated by shock while effectively reduce shock, and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a multi-dynamic hybrid shock absorber for construction. Background technique [0002] In the prior art, it includes a base, a steel plate, a fixed ring, a roller, a support seat, a track and a coil spring, the two sides of the upper surface of the base are provided with the fixed rings parallel to each other, and the inside of the fixed ring is provided with There are several sets of steel plates, the two ends of the highest steel plate are connected to the rollers through bearings, the two sides of the bottom surface of the support seat are provided with the tracks corresponding to the rollers, and the rollers are placed on the In the above-mentioned track, the coil spring is provided between the steel plate and the other two sides of the support seat, and the energy dissipation of the steel plate is used to offset the capacity. However, since the number of steel ...

[0002] In the prior art, it includes a base, a steel plate, a fixed ring, a roller, a support seat, a track and a coil spring, the two sides of the upper surface of the base are provided with the fixed rings parallel to each other, and the inside of the fixed ring is provided with There are several sets of steel plates, the two ends of the highest steel plate are connected to the rollers through bearings, the two sides of the bottom surface of the support seat are provided with the tracks corresponding to the rollers, and the rollers are placed on the In the above-mentioned track, the coil spring is provided between the steel plate and the other two sides of the support seat, and the energy dissipation of the steel plate is used to offset the capacity. However, since the number of steel plate groups in this device is small, the offset The energy is relatively small. In addition, if a relatively heavy object is placed in the device, it is likely to damage the mechanical properties of the steel plate, which has certain limitations.
