Abstract
The utility model relates to a self-locking railway steel rail clamping plate fastener, belongs to the technical field of railway track fixtures and mainly solves the problem that existing various broken rail emergency apparatuses fail to solve loosening and self-locking actually. The self-locking railway steel rail clamping plate fastener is mainly characterized by comprising left and right arced elastic clamping plates, left and right screws and left and right moving nuts; the left and right arced elastic clamping plates are both provided with clamping heads correspondingly matched with the shaped of the steel rail clamping plates on the upper portions, screw through holes in the middle and screw connecting hole seats matched with each other on the lower portions; locking grooves are arranged outside the middle screw through holes of the left and right arced elastic clamping plates; opposite threads are arranged on the left and right screws; and bosses matched with the locking grooves are arranged outside the left and right moving nuts. The self-locking railway steel rail clamping plate fastener has the advantages that the fastener is safe, reliable, long in service life and free of maintenance, speed of a train is not reduced after the use of the fastener, manual protection is omitted, and manpower and resources can be economized greatly. The fastener is mainly used for connecting steel rails with clamping plates after a railway rail is laid or rail is broken in building a railway.
Description
Technical field
The utility model belongs to railway track clamp technology field.Be specifically related to be used for after building railway track laying or rail fracture, connecting the anchor clamps of rail and clamping plate in a kind of situation not punching to rail, with the safe and punctual operation of assurance train, and have the advantages that train does not slow down or do not establish special messenger's protection.
Background technology
Along with railway speed raising several times, expedited the emergence of a Secretary " superlong jointless line ".Though being arranged, fastening-down temperature of rail etc. does the protection effect; but under specific environment; the tensile stress of rail inside and compressive stress; change along with environmental evolution, disconnected line and fracture all inevitably appear in its welding point, gluded joint; have a strong impact on the safe and punctual of railway; though existing have various broken rail emergency device to occur, actual problems that solves loosening and self-locking all, have in addition jeopardize safety and personal safety.
Summary of the invention
The purpose of this utility model be exactly provide for above-mentioned weak point a kind of safe and reliable, long service life, non-maintaining, use after train do not slow down, more do not need artificial protection, can save the self-locking railroad rail clamping plate fastener of a large amount of manpower and materials.
Technical solution of the present utility model is: a kind of self-locking railroad rail clamping plate fastener is characterized in that: comprise left camber resilient clamp plate, right camber resilient clamp plate, left-right rotary screw rod, left movable nut and right movable nut; Wherein, the top of left camber resilient clamp plate, right camber resilient clamp plate is the chuck with railways splint shape corresponding matching, and the middle part is equipped with screw vent, and the bottom is provided with the screw rod connecting hole seat of cooperation; The outside of left camber resilient clamp plate, right camber resilient clamp plate middle part screw vent is provided with locking groove; The left-right rotary screw rod is provided with two sections screw threads that hand of spiral is opposite, left movable nut, right movable nut respectively with these two sections threaded engagement; The outside that left movable nut, right movable nut and left camber resilient clamp plate or right camber resilient clamp plate are adjacent is provided with the boss that cooperates with locking groove.
The utility model is owing to adopt by left camber resilient clamp plate, right camber resilient clamp plate, the left-right rotary screw rod, the self-locking railroad rail clamping plate fastener that left movable nut and right movable nut consist of, wherein, left camber resilient clamp plate, the top of right camber resilient clamp plate is the chuck with railways splint shape corresponding matching, the middle part is provided with screw vent, the bottom is provided with the screw rod connecting hole seat of cooperation, left camber resilient clamp plate, the outside of right camber resilient clamp plate middle part screw vent is provided with locking groove, the left-right rotary screw rod is provided with two sections screw threads that hand of spiral is opposite, left movable nut, right movable nut respectively with these two sections threaded engagement, left movable nut, the outside that right movable nut and left camber resilient clamp plate or right camber resilient clamp plate are adjacent is provided with the boss that cooperates with locking groove, thereby in the situation of not punching, be used for building being connected of railway track laying and rail fracture place rail and clamping plate, first two clamping plate are put in rail junction or both sides, rail fracture place, make on the clamping plate, the lower end respectively with the rail inside groove on, the contact of lower corner, again with left camber resilient clamp plate, right camber resilient clamp plate places respectively two clamping plate both sides, make chuck be close to clamping plate, the left-right rotary screw rod passes left camber resilient clamp plate, right camber resilient clamp plate, left movable nut, right movable nut lays respectively at left camber resilient clamp plate, on the left-right rotary screw rod of right camber resilient clamp plate, rotation left-right rotary screw rod, left, right traveling nut does not rotate, with left camber resilient clamp plate, right camber resilient clamp board clamping reaches the effect of strap and rail.The bounce that is produced by camber resilient clamp plate reaches clamping " never becoming loose ", and the same screw rod that is comprised of left-right rotary reaches corresponding self-locking.The utlity model has safe and reliable, long service life, non-maintaining, use after train do not slow down, more do not need artificial protection, can save the characteristics of a large amount of manpower and materials.The utility model is mainly used in connecting the self-locking railroad rail clamping plate fastener of rail and clamping plate after building railway track laying or rail fracture.
