Abstract

The invention provides a locking device for a rail web-lifting steel rail damping fastener. The locking device for the rail web-lifting steel rail damping fastener comprises a rubber elastic damping block (1), a bottom plate (7), a support arm (2), a wedge block (3) and a fastener, wherein the rubber elastic damping block (1) is propped against a rail web of a steel rail; the bottom plate (7) is arranged at the lower part of the rubber elastic damping block (1) and supports the rubber elastic damping block (1); the bottom plate (7) extends upwards to form a side plate; the support arm (2) is propped against the outer side surface of the rubber elastic damping block (1); the wedge block (3) comprises an inner side surface of the wedge block and the outer side surface of the wedge block; the inner side surface of the wedge block is propped against the outer side surface of the support arm (2); the fastener is arranged on the lateral plate and is propped against the outer side surface of the wedge block (3); a first tooth surface which forms an included angle alpha together with the axis of the steel rail is arranged on the outer side surface of the wedge block; a second tooth surface which forms the included angle alpha together with the axis of the steel rail is arranged on the inner side surface of the side plate; the included angle alpha is greater than 0 degree and smaller than 90 degrees; and the first tooth surface is meshed with the second tooth surface.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a rail waist lifting type rail vibration damping fastener used for rail vibration isolation in urban rail transit, in particular to a locking device for a rail waist lifting type rail vibration damping fastener. Background technique [0002] While urban rail transit brings convenience to people's travel, the wheel-rail coupling vibration also brings vibration and noise pollution to surrounding buildings and residents. At this time, the use of vibration-damping fasteners on the track is an effective measure to reduce the vibration of the surrounding environment. [0003] The rail waist lifting type rail vibration damping fastener is a kind of vibration damping fastener with better vibration isolation performance at present, and the most representative one is the Pioneer fastener of the British Pandrol Company. The fastener has received widespread attention since it was produced, and m...
