Rail fastener bolt torque measurement re-tightening device
The invention discloses a track fastener bolt torque measurement re-tightening device, which comprises an angle measuring base plate, an angle amplifier and a semitransparent re-tightening wrench, and is characterized in that the angle measuring base plate is located above a pre-buried bottom plate and is provided with a central via hole for a fastener bolt to pass through, and 360-degree scale values are annularly arranged on the upper surface of the angle measuring base plate; the angle amplifier is of a fan-shaped structure, the inner end of the angle amplifier is in local butt joint with the angle measuring base plate, the local angle value of the outer side of the angle measuring base plate is amplified, the angle value, initially corresponding to the angle value of the angle measuring base plate, of the angular point of the outer hexagonal end of the fastener bolt serves as the initial angle value, and an opening matched with the outer hexagonal end of the fastener bolt is formed in the inner end of the semitransparent re-tightening wrench. When the loosening angle of the fastener bolt exceeds the limited loosening angle, the semi-transparent re-tightening wrench can stretch into and sleeve the outer hexagonal end of the fastener bolt to be screwed back to the initial angle value, and the fastener has the advantages that excessive torque is effectively avoided, potential safety hazards are reduced, the loosening state of the fastener is dynamically mastered, the bolt is quickly fastened, cost is reduced, efficiency is improved and the like.
本发明公开了一种轨道扣件螺栓扭矩测量复紧装置，包括量角垫板、角度放大器和半透明复紧扳手，所述量角垫板位于预埋底板上方，并设有中心过孔供扣件螺栓穿过，所述量角垫板上表面环向设有360°刻度值，所述角度放大器呈扇形结构且内端与量角垫板局部对接并放大量角垫板外侧局部角度值，所述扣件螺栓外六角端头的角点初始对应量角垫板的角度值作为初始角度值，半透明复紧扳手内端设有与扣件螺栓外六角端头匹配的开口，当扣件螺栓松动角度超过限定的松动角度时，能通过半透明复紧扳手伸入套住扣件螺栓外六角端头拧回初始角度值，具有有效避免扭矩过量、减少安全隐患、动态掌握扣件松动状态、实现快速紧固螺栓、降本增效等优点。
