The switch conversion equipment outer locking device and the installation device are important technical equipment for ensuring the speed-up and the transportation safety of heavy-load lines. The outer locking device and the mounting device realize the unlocking and locking of the turnout by the traction of the electric switch machine. The external locking device directly locks the close contact point rail and the stock rail of the turnout and keeps the repulsion off-rail at the standard opening position. Meanwhile, the outer locking device can isolate the vibration and impact of the train on the conversion equipment when the train passes through, and the service life and the reliability of the conversion equipment are improved. The switch machine has the functions of switching, locking and monitoring the rail, and the corresponding external locking circuit is mainly divided into an indoor control circuit, a turnout action circuit and a turnout indication circuit.
The external locking device is developed for ensuring the safety of the train after the speed is increased. The point and the stock rails (the point rail and the wing rail) are directly fixed in a close state through a locking device attached to the point and the stock rails (the point rail and the wing rail) after the point is directly locked with the stock rail, namely, the point is driven to a specified position by a point switch, and meanwhile, the repulsion separation rail is kept in a standard opening position. The external locking belongs to the direct locking, and is called an external locking device because the locking of the turnout is performed externally. The tail of the lock block of one type is in a dovetail shape, and the lock block is called as a dovetail type external locking device; the other method is to change a dovetail-shaped locking block into a locking hook, which is called a hook-type external locking device. Because there is no connecting rod between two switch rails of the external locking turnout, the two switch rails are respectively actuated in the turnout conversion process, so the turnout is also called as a transfer external locking turnout.
