Description

Tightly sticking and arresting gear for track switch rail

The utility model relates to a kind ofly stablizes the device of its tongue position when railway switch opens and closes the location, belong to railroad track superstructure technical field.

At present, the railway switch structure is opened and closed by the tongue of railway switch and to control forward and side direction driving.Connect into framework with cross-tie between two tongues, root is with fish tail metal plate and rails bolt, and the tongue framework lies on the metal bed-sliding plate, orders about tongue by goat and laterally moves on sliding bed, realizes opening or closure between tongue and stock rail.Because the constructional defective of railway switch, make two tip of a root rails be in a kind of labile state, under the impact and weight of train wheel, accident potential such as generation is beated, swing, the point of switch and stock rail are not closely connected, particularly under the high speed traveling situation, this unsafe factor is more outstanding, has constituted a big key subject of train speed raising.

The purpose of this utility model provides and a kind of tongue, metal bed-sliding plate and sleeper is connected as a single entity, and has the tightly sticking and arresting gear for track switch rail of dustproof facilities and locking device, strengthens the road switch blade and bears the ability that train impacts, and improves switch crossing speed, guarantees traffic safety.

The technical solution of the utility model is achieved in that this device includes parts such as bed-sliding plate for guiding slot, shifter, dustproof facilities, locking device and constitutes.Bed-sliding plate for guiding slot is installed on the sleeper with its wedged sleeper slot, and be connected with screw, the base sheath of "  " shape shifter is contained in the guide groove above the metal bed-sliding plate, and can move forward and backward along guide groove, the shifter bayonet socket blocks the tongue flange of rail, "T"-shaped head above the bayonet socket is connected with the tongue web of the rail with bolt, and two rollers are installed in proper order by its wheel shaft in the edge race of shifter bottom, in order to reduce the reciprocating frictional resistance of shifter.Article two, company covers arm and is welded respectively in bayonet socket upper lip two side ends, one end of four pumping rods of dust cover is screwed onto to connect and covers on the arm, the other end of pumping rod plugs with four longerons of dust cover framework respectively, dustproof framework solid welding is on the metal bed-sliding plate at shifter rear portion, at end face, two sides and the rear end face of the dust cover knot dustcloth that stretches tight, shifter is covered, to prevent the pollution of dust and dirt, above the guide groove between tongue and stock rail, a dustproof shell fragment is welded in the tongue bottom, above dustproof shell fragment, install a dustproof Sponge simultaneously additional, jointly guide groove is protected.Two tapered ends difference solid welding of locking device is on shifter two sides of tail metal bed-sliding plate face, lock shaft passes the lock shaft hole on the shifter, the lock shaft two ends are keyed jointing one locking bar respectively, when the point of switch and the closely connected need of stock rail lock, two locking bars are swung to fixedly tapered end, the convex head of locking bar is embedded in the Baltimore groove of fixing tapered end, trigonocephalia screw rod lock core run through to put the lock core trigonocephalia into the core hole of tapered end and locking bar with the triangle hole on key top fastening lock core, firm for guaranteeing to lock, to add lock pin on the locking bar dual-purpose hole and shifter on add in the lockhole, pass and add the locking of lock pin stomidium adding bright lock with one again.For making sleeper position Founder, be not subjected to displacement, be one group at per 4 to 5 sleepers of switch area, be 16cm with width, the steel plate of thick 1cm is connected to each other the sleeper two ends, and fills it up with the compacting ballast aggregate.

The utility model has following advantage:

1. moving by in the past slip of tongue becomes rolling by the shifter return pulley, greatly alleviated the tongue frictional resistance, more helps the closely connected of tongue and stock rail.

2. the combination of this device, it is whole to make tongue become a carrying by shifter and splice bar, sleeper and even railway roadbed, controlled tongue produces beat, swing or jump effectively under the wheel effect, thereby the gauge, direction, planeness that make tongue have improved the track switch quality stressed or do not have under the external force situation and all can remain intact state.

3. when tongue is shifted to stock rail, utilize the locking device that the tongue of location is firmly pinned, effectively controlled the trickle of the point of switch and moved, guarantee traffic safety.

4. enabling of dustproof facilities improved the track switch cleaning ambient, and created good condition for the snow removing in winter, alleviated personnel labor.
