Abstract

The present invention relates to rail switching device, and is especially one kind of rail switching device for electrically controlled switch. The rail switching device includes an electric controller and a driver to connect the electric controller to the rail. The electric controller has a power machine and a push rod connected to the power machine. The switch controlling process includes the steps of changing voltage, converting the rotating force into linear force with the motor, changing drive moment mechanically and pushing or pulling the switch rail with the driver, and has great drive moment and small operating current. The rail switching device has also built-in lead screw, small DC permanent motor, inside micro reducer and contact-less stroke switch, and possesses reduced size, raised reliability and capacity of realizing automatic control.

Description

technical field [0001] The invention relates to a track switch machine, in particular to a track switch device controlled by an electric driver. Background technique [0002] At present, railways, mines, metallurgy, and power plants generally use rails to transport goods. When transferring the transported goods from one track to another, it is generally to move the switch machine, which changes the track and makes the truck change its driving. For the track route, the moving switch machine is generally controlled manually or automatically, and the movement of the switch rail is controlled to make the track switch. [0003] The existing pneumatic turnout switch machine converts electric energy into air compressed gas, and uses the cylinder to push the connecting rod to perform track switching. The pneumatic turnout switch needs to convert electric energy into air compressed gas, and the torque is small and the current is large. , In coal mine ro...
