Abstract

The invention provides an external locking device used for a turnout. The external locking device comprises two locking hooks (36) and two locking rods (38-1 and 38-2), and the locking rods are arranged to be matched with the locking hooks so that movement of the locking rods (38-1 and 38-2) can drive the two locking hooks (36-1 and 36-2) to switch between a locking state and an unlocking state, wherein the two locking rods are connected to each other through a connecting assembly, and the connecting assembly and at least one of the locking rods are arranged to enable the length of the part, between the two locking hooks (36), of the locking rods (38-1 and 38-2) to be adjustable.

Description

technical field [0001] The present invention relates generally to rail vehicles, and more particularly to an external locking device for a switch. Background technique [0002] A turnout is a line connecting device that enables a rolling stock, for example, to transfer from an A-share track to a B-share track. The most common is the common single-opening turnout, which includes a switch, connecting parts, frogs and guard rail parts, etc. A switch includes, for example, two stationary base rails, two movable switch rails and a switch mechanism. When the rolling stock is going to transfer from the A-share track to the B-share track, the switch mechanism makes the two switch rails move, that is, switch from the switch rail and the first basic rail close to the switch to the point rail detaching from the first basic rail and connecting with the second The basic rail is closely attached. In this way, the B-share track is opened and the A-share track is closed. [0003] With t...
