Abstract

The invention relates to a vibration reduction type urban rail frog switch which comprises stock rails, switch rails, a steel rail joint structure and a frog vibration reduction supporting structure, the stock rails comprise a straight stock rail and a curved stock rail, the switch rails comprise a curved switch rail and a straight switch rail, the curved stock rail and the curved switch rail are used for side strand passing, and the rail joint structure comprises a steel rail joint structure and a frog vibration reduction supporting structure. The straight stock rail and the linear switch rail are used for straight strand passing, the straight stock rail and the curved stock rail are connected through the spacer iron, the curved stock rail and the linear switch rail are connected through the spacer iron, the steel rail joint structure is arranged at the connecting position of adjacent steel rails, and the railroad switch vibration reduction supporting structure is arranged below an urban rail line running rail. The rail gauge change rate in the switch rail range is reduced, the operation stability of a train in the turnout range is improved, the vibration influence of the train on surrounding buildings is reduced fundamentally, meanwhile, the vibration reduction type supporting structure is of an upper locking type structure, and meanwhile later maintenance of a public work department is facilitated.

Description

technical field [0001] The invention relates to the field of traffic engineering, in particular to a vibration-damping city track switch switch. Background technique [0002] Rail transit has the advantages of large capacity, high speed, high punctuality rate, and novel comfort. It is complementary to traditional transportation such as high-speed rail, aviation, and public transportation. It is a means of transportation with good development prospects. However, the construction of rail transit has also brought some environmental pollution to the residents along the line. Turnout is an important subsystem of the rail system, which directly affects the safe operation of the rail system and even the entire rail transit system. Turnouts can be divided into different numbers according to their frog angles, including No. 9 turnout, No. 7 turnout, and No. 12 turnout. The greater the number of turnouts, the greater the allowable speed in the vertical and lateral directions, and vi...
