Embodiment Construction

[0030] Such as figure 1 , 2 , 3, the light pole shock absorber of the present invention includes a housing 2, the housing is composed of a chassis 4, a cylindrical side wall 3 and a top cover 5, the chassis 4 is a concave disc shape, and the chassis 4 is equipped with A plurality of rigid balls 1, the contact surface between the chassis 4 and the rigid balls 1 is provided with a sound-absorbing damping layer.

[0031] The noise damping layer is a vulcanized rubber layer with a thickness of 1mm.

[0032] Both the chassis 4 and the top cover 5 are in sealing connection with the cylindrical side wall 3 in the form of flanges. The flange structure of the chassis 4 has mounting holes 6 for connecting light poles.

[0033] The light pole shock absorber of the present invention is installed on the top of the street lamp light pole when in use.

[0034] The determination process of the specific parameters of the light pole shock absorber is as follows:

[0035] The main vibration...

Abstract

The invention discloses a lamp-post oscillating damper, which comprises a shell, wherein the shell consists of a chassis, a cylindric lateral wall and a capping. The chassis has a concave disc shape, the disc is provided with a plurality of rigidity balls; the contact surface of the disc and the rigidity balls is provided with a damping muffler layer; and the damping muffler layer is a vulcanizedrubber layer and the thickness of the vulcanizedrubber layer is 0.8 to 1.2mm. The lamp-post oscillating damper is made by adopting multi-sphere rolling technology, is mainly used for wind vibration resistance of a lamp post with a slender structure, can also be used in the field of wind resistance and earthquake resistance of towering billboards and city high-pole lamps, has good vibration decreasing effect and small volume, and can be suitable for vibration decreasing of multiple frequency. The lamp-post oscillating damper has low cost, simple structure and obvious vibration decreasing effect.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a light pole shock absorber. Background technique [0002] In recent years, the safety of structures has been paid more and more attention. In coastal and high wind speed areas, the damage of urban light pole lighting systems is basically caused by vibration. Due to the low frequency of wind vibration of the light pole, the thin structure or beautiful appearance is not suitable for installing a large-volume damping mechanism, and the overall cost of the lighting system is low. Therefore, the existing light pole lighting system basically does not install a vibration damping device. [0003] For example, Chinese utility model patent 93226691.6 discloses a street lamp shock absorber, which is composed of a top cover, a quadric body, a fluid damping medium, and a metal mass ball, and is installed on the top of a street lamp pole. The shock absorber produces the same vibration frequenc...
