Low-installation-height and high-blocking-shoulder vibration reduction type fastener assembly and preassembling method thereof
The invention discloses a low-installation-height and high-retaining-shoulder vibration reduction type fastener assembly which comprises a height adjusting plate, an elastic cushion plate, a top plate, anchor bolts, distance adjusting blocks and elastic strips. The left shoulder damping plate and the right shoulder damping plate have a transverse damping function, the foundation frame is provided with a damping cavity which is communicated up and down, the height adjusting plate is padded on the sleeper, the foundation frame is pressed on the height adjusting plate, the elastic cushion plate is installed in the damping cavity of the foundation frame, and the left shoulder damping plate and the right shoulder damping plate are arranged in the damping cavity. The left blocking shoulder vibration reduction plate and the right blocking shoulder vibration reduction plate are vertically installed on the left side and the right side in the vibration reduction cavity respectively, the top plate is located between the left blocking shoulder vibration reduction plate and the right blocking shoulder vibration reduction plate and pressed on the elastic cushion plate, the distance adjusting blocks are pressed on the two sides of the top plate to control rail feet on the two sides of the steel rail, and the distance adjusting blocks are pressed by the elastic strips. The device has the advantages that any damaged part in the left retaining shoulder vibration reduction plate, the right retaining shoulder vibration reduction plate and the elastic base plate can be flexibly replaced; the assembly integrity of the left shoulder damping plate, the right shoulder damping plate, the elastic base plate and the top plate is enhanced; and the mounting height of the steel rail is reduced.
本发明公开了一种低安装高度高挡肩减振型扣件组合体，包括调高板、弹性垫板、顶板、锚固螺栓、调距块和弹条。还包括基础架和具有横向减振功能的左挡肩减振板、右挡肩减振板，基础架具有上下相通的减振空腔，调高板垫在轨枕上，基础架压在调高板上，弹性垫板安装在基础架的减振空腔内，左挡肩减振板和右挡肩减振板分别竖向安装在减振空腔内的左右两侧，顶板位于左挡肩减振板和右挡肩减振板之间并压在弹性垫板上，调距块压在顶板两侧控制钢轨两侧轨脚，由弹条压住调距块。优点在于：能够灵活更换左挡肩减振板、右挡肩减振板和弹性垫板中受损的任何一个部件；增强了左挡肩减振板、右挡肩减振板、弹性垫板、顶板装配的整体性；降低了钢轨的安装高度。
