Multiple-power mixed vibration damper for buildings

Abstract

The invention discloses a multi-dynamic hybrid shock absorber for construction, which comprises a bottom support plate and a top support plate. The upper surface of the bottom support plate is provided with an electromagnetic hollow shell with an integral structure with it on opposite sides. The electromagnetic hollow shell is provided with an iron core at the bottom, the side surface of the iron core is fixed inside the coil, and the electromagnetic hollow shell is provided with an electromagnetic hollow shell directly above the iron core. Using a hollow structure, a permanent magnet is placed inside the electromagnetic hollow structure, an electromagnetic movable plate is placed on the upper surface of the permanent magnet, and an electromagnetic push rod is fixed on the top of the upper surface of the electromagnetic movable plate. The invention can combine the energy consumption of the steel plate, the gas flow and the electromagnetic effect, so as to form a variety of dynamic hybrid shock absorption effects, and can combine the advantages of the three kinds of shock absorption. The energy caused by vibration has strong practical performance.

Description

technical field [0001] The invention relates to the technical field of construction machinery, 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.
