Turnout beam drive device of straddle type monorail turnout and straddle type monorail turnout

Abstract

The invention discloses a turnout beam drive device of a straddle type monorail turnout and the straddle type monorail turnout. The turnout beam drive device comprises a guide rod and a rotary drive component, wherein one end of the guide rod is rotationally fixed to the ground, and a thread is arranged on the guide rod; the rotary drive component is rotationally connected to the position below aturnout beam and comprises a drive motor and a first gear, the first gear is in thread fit with the guide rod and is in transmission with the drive motor, and therefore the guide rod is driven by thedrive motor through the first gear to rotate around the fixed end of the guide rod. Through arrangement of the first gear and the guide rod, the turnout beam can be driven to move in a thread drive mode, and vibration and noise of the whole turnout beam in the operation process can be effectively reduced in the mode. In addition, the occupied ground space of the turnout beam drive device can be reduced as well, and the arrangement reasonability and reliability of the turnout beam drive device can be improved.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a turnout beam driving device of a straddle-type single track switch and a straddle-type single track switch having the drive device of the turnout beam. Background technique [0002] In the related art, the straddle-type single track turnout generally drives the turnout beam to run through the turnout beam driving device. Specifically, the turnout beam driving device generally includes a turning arm, and the turnout beam driving device rubs against the chute at the bottom of the turnout beam through the roller at the end of the turning arm. drive, so that 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, this requires high manufacturing precision for the foundation and t...

[0002] In the related art, the straddle-type single track turnout generally drives the turnout beam to run through the turnout beam driving device. Specifically, the turnout beam driving device generally includes a turning arm, and the turnout beam driving device rubs against the chute at the bottom of the turnout beam through the roller at the end of the turning arm. drive, so that 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 gear coupling

However, this requires high manufacturing precision for the foundation and the bottom plate, and it is difficult to guarantee 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.
