Locking type damping steel rail iron sheet composite structure

Abstract

The invention relates to a locking type damping steel rail iron sheet composite structure. The locking type damping steel rail iron sheet composite structure comprises an upper iron sheet, an elastic sheet, a lower iron sheet and a locking sleeve structure. The elastic sheet is sandwiched between the upper iron sheet and the lower iron sheet, the locking sleeve structure is used for locking the upper iron sheet, the elastic sheet and the lower iron sheet, a tubular structure of the lower iron sheet is sleeved with a positioning nest, the tubular structure of the lower iron sheet sequentially penetrates through the elastic sheet and the upper iron sheet and is carried on a first boss of the upper iron sheet through a second boss, a C-shaped gap is reserved in the outer ring of a first through hole, a positioning locking sleeve is wedged into the C-shaped gap, and therefore the damping steel rail iron sheet composite structure is assembled. The locking type damping steel rail iron sheet composite structure is ingenious in concept, good in safe reliability and good in damping effect, vibration of the iron sheet composite structure can be effectively lowered, displacement between the upper iron sheet and the lower iron sheet is avoided, in addition, the upper portion of the iron sheet composite structure can be locked, and therefore the locking type damping steel rail iron sheet composite structure is convenient to install.

Description

technical field [0001] The invention relates to the field of rail fasteners, in particular to an iron backing plate combination structure in a rail fastener, in particular to a lock-type damping rail iron backing plate combination structure. Background technique [0002] Rail transit projects have been widely used in national railway passenger and freight transportation, urban passenger transportation and other fields, and have developed rapidly in recent years, especially urban rail transit projects, including subways, light rails, trams, etc. An effective solution to the problem of traffic congestion. However, while the railway transportation system brings convenience to people's life and production activities, it is also becoming a new source of noise and vibration. Especially in dense residential areas, commercial centers and industrial areas, the railway traffic system has caused vibration and noise pollution that cannot be ignored. [0003] Especially in dense reside...
