Abstract

The utility model discloses a new straight line type electric switching machine, comprising a new straight line type electric machine and a control circuit. The utility model comprises a mover, a stator winding, a mover pole block, a round iron sheet, a positioner winding and a contactor. The magnetic field drawing force generated between a stator magnetic pole and a corresponding mover induction pole block impels the mover pole block to move, and thus the mover is driven to move. The new straight line type electric switching machine not only has big driving force and favorable performance but also has the advantages of simple structure, light weight and small size, and the utility model is suitable for the railway transportation in various situations and for the wrench of the rail switch for railway transportation under the mine.

Description

Straight line type electric switching machine
The utility model is to belong to the motor technology field that is used to pull railway transportation track switch.
Be used for pulling the electric switch machine of railway switch, especially mine railway transportation electric switch machine fails to obtain fine solution for a long time, and this transports railway security and makes troubles.With regard to existing electric switch machine, if adopt rotary asynchronous motor to constitute, it not only needs the rotation motion motion that be in line, and rotating speed height, output torque is little, increase moment, and promptly adding slows down increases the device of moment, will make big, the Heavy Weight of electric switch machine volume, and complex structure.If adopt the straight line asynchronous motor to constitute, equally also have the little shortcoming of output torque.
The purpose of this utility model is to provide a kind of novel linear formula electric switch machine, and it is to adopt a kind of novel linear electrical motor, has overcome by asynchronous motor and has constituted the little shortcoming of the existing output torque of electric switch machine.
The core of novel linear formula electric switch machine is exactly the novel linear electrical motor, mixes control path again.This novel linear electrical motor comprises stator winding, runner pole block (rotor that is equivalent to rotary electromotor) and mover (being equivalent to the rotating shaft of rotary electromotor).Runner pole block is fixed on the mover, does not have winding on the runner pole block, and stator winding electrifying produces magnetic field.When the magnetic pole of magnetic pole of the stator and runner pole block (being produced by fixed induction) when position of center line is inconsistent, the magnetic field that the stator winding electric current is produced produces tensile force by the magnetic line of force of runner pole block, makes the runner pole block motion, moves thereby drive mover.For the ease of remote handing, the utility model has been equipped with the remote operated control setup.
The utility model not only thrust is big, performance is good, and simple structure, in light weight, volume is little, be applicable to the railway transportation track switch of various occasions, especially concerning limited place, mine underworkings locus, pull its railway transportation track switch, this novel linear formula electric switch machine will be more suitable.
Accompanying drawing 1 expression runner pole block moves stressed in magnetic field and situation magnetic line of force.
