Anti-tilting cleaning-free comb plate telescopic device
The invention belongs to a telescopic device, and particularly relates to an anti-tilting cleaning-free comb plate telescopic device. The root of the movable comb plate is connected with one side beam end or a bridge abutment, the front portion of the movable comb plate is in lap joint with the expansion joint, the fixed comb plate is opposite to comb teeth of the movable comb plate and fixed to the other side beam end or the bridge abutment, a fixed comb plate base plate is arranged below the lap joint portion of the two comb plates, and a rubber water stop belt is arranged in the expansion joint. A rotating sleeve coaxial with the expansion joint is arranged at the beam end or the bridge abutment on one side of the root of the movable comb plate, a rotating shaft is rotatably matched in the rotating sleeve, the root of the movable comb plate is fixed to the rotating shaft and can rotate along the rotating sleeve, and a corner gap is formed between the lower surface of the root of the movable comb plate and the beam end or the bridge abutment below the movable comb plate. An outlet of the ventilation pipe is located in the lower portion of the movable comb plate and/or the fixed comb plate and faces the space defined by the comb teeth of the movable comb plate and/or the fixed comb plate. The comb plate solves the problem that in the prior art, a toothed plate is prone to upwarp to be damaged, and has the advantages that the toothed plate is not prone to upwarp, and sundries are not prone to accumulation in gaps of the comb plate.
本发明属于伸缩装置，特别是指一种防翘起免清洁梳齿板伸缩装置。包括根部与一侧梁端或桥台连接且前部搭接于伸缩缝上的活动梳齿板，与其梳齿相对且固定于另一侧梁端或桥台的固定梳齿板，两梳齿板搭接部下方设有固定梳齿板垫板，伸缩缝内设有橡胶止水带；位于活动梳齿板根部一侧的梁端或桥台上设有与伸缩缝同轴向的转动套，转动套内转动配合有转动轴，活动梳齿板根部与转动轴固定且可沿转动套转动，其根部下表面与下方的梁端或桥台设有转角间隙，通气管的出口位于活动梳齿板和/或固定梳齿板下部且朝向二者梳齿所围绕的空间。本发明解决了现有技术中存在的齿板易翘起导致损坏等问题，具有齿板不易翘起、梳齿板缝隙不易积累杂物等优点。
