Fastener device for impact resistance and insulation of tramcar
The invention discloses a fastener device for the impact resistance and the insulation of a tramcar. The device comprises a sleeper and a steel rail arranged on the sleeper, embedded sleeves which are symmetrically arranged relative to the cross section center line of the steel rail are arranged on the sleeper, internal threads are arranged in the embedded sleeves. Insulating liners, gauge baffles, baffle seats and elastic strips are arranged on the two sides of the steel rail. a screw spike penetrates through the elastic strips and the gauge apron and is in threaded connection with the embedded sleeve. Compared with the prior art, the fastener device has the advantages that the fastener device is suitable for sleepers with retaining shoulder structures, the gauge apron, the screw spikes and the elastic strips are used in cooperation, fixation is firmer, and the fastening force is guaranteed. The device is simple in structure, convenient to install, position and maintain, and capable of better meeting the development of tramcars in the future.
本发明公开了一种用于有轨电车耐冲击绝缘的扣件装置，包括轨枕和设置在轨枕上的钢轨，在轨枕上设置有相对于钢轨的断面中心线对称布置的预埋套管，预埋套管内设置有内螺纹，在钢轨的两侧均设置有绝缘衬、轨距挡板、挡板座和弹条，螺旋道钉穿过弹条和轨距挡板，与预埋套管螺纹连接。与现有技术相比，本发明的积极效果是：本发明的扣件装置适用于有挡肩结构的轨枕，通过轨距挡板、螺旋道钉、弹条配合使用，固定更加的牢靠，保证扣压力。本发明结构简单，便于安装定位，维修方便，能够更好地满足未来有轨电车的发展。
