Bolt anti-loosening device for railroad sleeper
The invention relates to a bolt anti-loosening device for a railway sleeper, and discloses a bolt anti-loosening device which can form screwing forces on nuts on bolts by utilizing the driving power of a railway train, so that the nuts can be screwed and fixed and the bolts can be prevented from loosening due to the vibration generated by the train. The bolt anti-loosening device for the railway sleeper is characterized in that a plurality of hemispherical sliding points are annularly arranged at the bottom end of a hexagonal sleeve at equal intervals; a connecting column is fixedly arranged at the top end of the hexagonal sleeve; the connecting column is of a hollow structure; the bottom end of a fixing shaft penetrates through the middle of the connecting column; two bearings are arranged between the fixing shaft and the connecting column; the two bearings are close to the two sides of the fixing shaft respectively; two limiting rings are fixedly arranged on the fixing shaft and located at the two sides of the connecting column respectively; a plurality of sliding grooves are formed in the inner wall of the connecting column at equal angles; a plurality of grooves corresponding to the sliding grooves in a one-to-one mode are formed in the fixing shaft; springs are arranged in the sliding grooves; and one ends of the springs are connected with the groove bottoms of the slidinggrooves.
本发明一种铁路轨枕用螺栓防松器公开了一种能够利用铁路列车的行驶动力形成对螺栓上螺母的旋拧力，能够对螺母进行旋拧固定，避免螺栓因列车产生的震动而松动的螺栓防松器，其特征在于多个半球滑点环形等距置于六角套底端，连接柱固定置于六角套顶端，连接柱为中空结构，固定轴底端穿过连接柱中部，固定轴和连接柱之间设置有两个轴承，两个轴承分别靠近固定轴两侧，两个限位环固定置于固定轴上，两个所述限位环分别位于连接柱两侧，连接柱内壁上等角度开有多个滑槽，固定轴上开有与多个滑槽一一对应的多个凹槽，弹簧置于滑槽内，弹簧一端和滑槽槽底相连接。
