Turnout beam driving device, turnout and rail

Abstract

The invention provides a turnout beam driving device. The device comprises a connecting rod mechanism and a driving assembly, wherein the connecting rod mechanism comprises push rods, swing rods and aconnecting rod, one ends of the push rods are connected with a turnout beam, the other ends of the push rods are connected with the swing rods, one ends of the swing rods are fixed through a fixing mandrel, the other ends of the swing rods are connected with the connecting rod, and the swing rods are suitable for rotating around the fixing mandrel; and the driving assembly comprises a driving source and a driving rod, wherein the driving rod is connected with the connecting rod mechanism, and the driving source drives the connecting rod mechanism through the driving rod. The turnout beam driving device is simple and reliable in structure, convenient to assemble and disassemble, low in cost and capable of reducing vibration and noise of the turnout beam.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a turnout beam driving device and a turnout and a track provided with the turnout beam driving device. Background technique [0002] In the related art, the single track turnout generally drives the turnout beam to switch through the turnout beam driving device. Specifically, the turnout beam driving device generally includes a turning arm, and the turnout beam driving device is frictionally driven by the roller at the end of the turning arm and the chute at the bottom of the turnout beam. The vibration is large and the noise is large, and the turnout beam driving device can also include four switch reducers, and the four switch reducers are connected in series through the transmission shaft and the drum-shaped gear coupling. However, such a mechanism is complicated, and requires high manufacturing precision for the foundation and the base plate, so it is difficult to...

[0002] In the related art, the single track turnout generally drives the turnout beam to switch through the turnout beam driving device. Specifically, the turnout beam driving device generally includes a turning arm, and the turnout beam driving device is frictionally driven by the roller at the end of the turning arm and the chute at the bottom of the turnout beam. The vibration is large and the noise is large, and the turnout beam driving device can also include four switch reducers, and the four switch reducers are connected in series through the transmission shaft and the drum-shaped gear coupling

However, such a mechanism is complex, and requires high manufacturing precision for the foundation and floor, so it is difficult to ensure the installation accuracy of the entire mechanism. In addition, since the driving device is installed on the ground foundation, it occupies a large area, which is not conducive to the safety of the turnout system.
