Embodiment 1

[0047] Such as Figure 3-4 As shown, this embodiment provides a floating fixing device for fixing between the floating rail fastener and the steel rail 10. The floating fixing device includes a bottom plate 1, a supporting side plate 2, an elastic wedge 3 and a positioning wedge 4. The bottom plate 1 is set on the lower part of the rail 10, and the elastic wedges 3 are fixed on both sides of the rail waist of the rail 10 to limit the lateral displacement of the rail 10. One end of the supporting side plate 2 is connected to the bottom plate 1, and the other end is connected to the elastic wedge 3 are fixedly connected, so that the two supporting side plates 2 respectively fix the two elastic wedges 3 on both sides of the rail waist. A shoulder 8 is arranged on the bottom plate 1, and the positioning wedge 4 is installed between the shoulder 8 and the supporting side plate 2, so that the supporting side plate 2 is clamped to the elastic wedge 3.

Abstract

The invention provides a floating fixing device. The floating fixing device comprises a bottom plate, supporting side plates, elastic wedge blocks and positioning wedge blocks, wherein the bottom plate is arranged on the lower portion of a steel rail, the elastic wedge blocks are fixed to the two sides of a rail web of the steel rail through the supporting side plates, blocking shoulders are arranged on the bottom plate, and the positioning wedge blocks are installed between the blocking shoulders and the supporting side plates. The floating fixing device further comprises fastening and pressing assemblies, and the fastening and pressing assemblies fasten and press the positioning wedge blocks and the steel rail, or the fastening and pressing assemblies fasten and press the steel rail through the positioning wedge blocks. The fastening and pressing assemblies fasten and press the positioning wedge blocks to prevent the positioning wedge blocks from floating upwards, so that the steel rail is transversely clamped and kept in a suspended state; and the fastening and pressing assemblies fasten and press the steel rail and have the vertical limiting capacity on the steel rail, so thatthe vertical acceleration of the steel rail is reduced, the use of hydraulic clamping tools of floating rail fasteners is reduced, and the installation efficiency is improved. Dual and bidirectional limiting is achieved, the stability of the fasteners is improved, and the safety of a journey is guaranteed. On the other hand, the fastening and pressing assemblies are connected with the bottom plateto be fixed, so that the fastening and pressing assemblies are prevented from floating upwards.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a floating fixing device. Background technique [0002] In recent years, my country's subway, light rail and other urban rail transit systems have developed rapidly, effectively alleviating the tension in urban traffic, but how to control the vibration and noise pollution generated during the operation of rail transit has become an urgent problem to be solved. The application of vibration and noise reduction fasteners is an effective treatment method. The traditional fastener system is to install one or more layers of low-rigidity elastic backing plates under the rails, the upper part is fastened by elastic strips to the rail foot, and the lower part is connected by a spike system. It is easier to realize the connection method of this kind of elastic strip buckling rail foot, but this buckling method leads to a large torsional moment arm between the stressed part (rail head) and the ...
