Lever structure type vibration absorber
The invention discloses a lever structure type vibration absorber which comprises a magnetic attraction base, a lever, a base and a sound absorption and vibration reduction block. The first end of the lever is rotationally connected with the magnetic attraction seat; the sound absorption and vibration reduction block is arranged at the second end of the lever; the base is rotationally connected to a first point on the lever and supports the lever through the first point, and the first point is located between the first end and the second end of the lever; the magnetic attraction seat is magnetically connected with a steel rail; vibration of the steel rail is transmitted to the sound absorption and vibration reduction block through the magnetic attraction base and the lever in sequence, and the received vibration of the steel rail is reduced through vertical movement of the sound absorption and vibration reduction block. According to the lever structure type vibration absorber, the magnetic attraction base is connected with the rail web of the steel rail through magnetic force and is directly attached to the rail web, the lever and the base form the lever principle, the lever amplification effect of the lever is achieved based on the lever principle, and compared with a conventional vibration absorber, the working performance of the lever structure type vibration absorber is improved on the premise that the mass of the vibration absorber is not increased.
本发明公开了一种杠杆结构型吸振器，包括：磁吸座、杠杆、底座和吸声降振块；所述杠杆的第一端与所述磁吸座转动连接；所述吸声降振块设置于所述杠杆的第二端；所述底座转动连接于所述杠杆上的第一点，并通过所述第一点对所述杠杆进行支撑，所述第一点位于所述杠杆的第一端与第二端之间；所述磁吸座通过磁性连接钢轨；钢轨的振动依次通过所述磁吸座、杠杆传递至所述吸声降振块，经过所述吸声降振块的上下运动对接收到的钢轨的振动进行降低。本发明提供的杠杆结构型吸振器的磁吸座通过磁力连接钢轨轨腰直接紧贴，杠杆与底座构成杠杆原理，基于杠杆原理发挥其杠杆放大作用，相较于常规型吸振器在在不增大吸振器质量的前提下提升其工作性能。
