Problems solved by technology

[0002] At present, the sleeper-type external locking and installation devices generally use hook-type external locking devices and direct-connected rod-type installation devices, which have problems with the hook and connection caused by the swing of the switch rail, the flipping of the lock hook, and the irregularity of the turnout during the switch conversion process. Locking of the pin shaft, decoupling phenomenon of the lock hook at the repelling position, jumping of the iron pin shaft and the switch rail connecting the lock hook and the switch rail, the impact force of the display structure generated by the vibration changes the size of the switch machine display gap, etc. Maintenance and operation have a certain impact

Abstract

The invention discloses a sleeper type external locking device and an installation device matched with the sleeper type external locking device, and belongs to the technical field of turnout switchingequipment. The sleeper type external locking device is used for locking a point rail and a basic rail at a turnout, and comprises a locking hook and a locking rod, wherein the locking hook is used for being connected with the point rail; the locking hook and the locking rod are in concave-convex connection; a protrusion on the locking rod can be embedded into a groove at the lower part of the locking hook; the locking hook can be driven to switch between a locking state and an unlocking state through the movement of the locking rod; the two sides of the locking hook are respectively fixedly connected with a limiting plate; the extending ends of the limiting plates are positioned on the two sides of the locking rod; and a connecting rod is connected between the extending ends of the two limiting plates to limit the locking rod in the space between the connecting rod and the locking hook. According to the sleeper type external locking device, the limiting plates are arranged on the twosides of the locking hook, so that the locking hook better adapts to the crawling of the point rail, the abrasion of an iron pin shaft and locking iron connecting the locking hook with the point railis reduced, and the unhooking phenomenon of the locking hook in the repulsion position is effectively prevented.

Description

technical field [0001] The invention relates to the field of switch conversion equipment, in particular to a sleeper type external locking device and an installation device used in conjunction with it. Background technique [0002] At present, the sleeper-type external locking and installation devices generally use hook-type external locking devices and direct-connected rod-type installation devices, which have problems with the hook and connection caused by the swing of the switch rail, the flipping of the lock hook, and the irregularity of the turnout during the switch conversion process. Locking of the pin shaft, decoupling phenomenon of the lock hook at the repelling position, jumping of the iron pin shaft and the switch rail connecting the lock hook and the switch rail, the impact force of the display structure generated by the vibration changes the size of the switch machine display gap, etc. Maintenance and operation have a certain impact.
