Suspension type rail transit telescopic device
The invention discloses a suspension type rail transit telescopic device. The device comprises two steel beams which are symmetrically arranged; a gap is formed between the two steel beam bottom plates; joints of the two steel beams form telescopic connection through telescopic devices respectively; the telescopic devices at the joints of the two steel beams are symmetrically arranged and fixed toa steel beam bottom plate; each telescopic device comprises a first tooth-shaped plate and a second tooth-shaped plate which are meshed with each other; comb-shaped teeth on the first tooth-shaped plates are of an oblique tooth structure; and comb-shaped teeth on the second tooth-shaped plates are of an oblique tooth and straight tooth mixed structure. The suspension type rail transit telescopicdevice is simple in structure; the telescopic devices can be detached and replaced; excessive vibration generated when a train passes through the steel beam joints can be effectively avoided, so thatnoise is reduced.
本发明公开了一种悬挂式轨道交通伸缩装置，包括两个相互对称设置的钢梁，两钢梁底板之间形成间隙，两钢梁的接缝处分别通过伸缩装置构成伸缩连接，两钢梁接缝处的伸缩装置相互对称设置，伸缩装置固定在钢梁底板上，所述伸缩装置包括相互齿合的第一齿形板和第二齿形板，第一齿形板上的梳形齿为斜齿结构，第二齿形板上的梳形齿为斜齿加直齿混合结构。本发明结构简单，伸缩装置可拆卸更换，能有效避免列车经过钢梁接缝时产生过大震动，减小噪音的产生。
