Movable core way fork core rail hook lock deviceTechnical Field
The utility model relates to the technical field of rails, in particular to a movable turnout core rail hooking and locking device.
Background
The switch hook locking device is a device which can fasten the switch close point rail (movable point rail) and the stock rail (wing rail) together by manual method and fix the repulsive point rail at a certain position to lock the access way so as to prevent the switch from being manually or erroneously pulled. It is suitable for railway station, single-split switch, double split switch, AT-rail switch, speed-raising switch and movable-point switch. When train is connected and sent on a line without a chain or in a maintenance state of a chain automatic device, the protection turnout on the opposite turnout and the adjacent turnout on the line is locked so as to ensure the running safety of the train. The device can also be used for preventing personal injury by propping against the switch point when cleaning the switch. The traditional movable core rail fork hook lock consists of a rail clamping seat, a screw rod and a spanner. When in use, the hook seat is clamped at the bottom of the movable core rail, the screw rod is propped against the rail wing, and the movable core rail is locked by tightening the screw.
Conventional switch hook locks cannot be positioned on such a point and thus cannot reliably lock the point rail. Therefore, the conventional switch hook lock is not suitable for a movable point rail switch in which the point rail tip of the frog is of a triangular block type integral structure.
The patent document with the publication number of CN201670252U proposes a movable core rail fork core rail hook lock device, which comprises a screw rod, wherein the middle part of the screw rod is fixedly connected with a core plate, and a rotation-resisting boss is arranged on the core plate; two ends of the screw rod are respectively connected with rail base clamping seats with opposite bayonets in a penetrating way, and locking lugs with locking holes are arranged on two sides of the rail base clamping seats; the outer side ends of the two rail base clamping seats are respectively screwed with lock plate nuts; one end of the screw rod is connected with a lifting ring. The utility model has simple structure, convenient operation, safety and reliability; the locking device can be used for locking the movable point rail when the turnout is in the normal position or in the reverse position. The utility model is not only suitable for the point rail locking of the movable point rail turnout with the point rail tip of the frog being of a triangular block type integral structure, but also can be used for the point rail locking of the movable point rail turnout with an AT steel rail splicing structure.
However, after the rail is locked, the nut is easy to loosen due to vibration generated after the train passes through, so that the device has certain limitation.
Therefore, it is desirable to provide a movable turnout rail coupler.
