Abstract

The utility model discloses a detachable slide plate, which detaches a slide plate from a slide plate sleeve. A slide plate groove is arranged inside the slide plate sleeve; a shoulder and a nylon seat are installed on the both sides of the slide plate. When the gage correction of the railway maintenance, only the nylon seat type needs to be changed, and the slide plate is correspondingly moved. Using the same slide plate sleeve, the work of the replacement of the ordinary tongue rail or the AT tongue rail can be carried out, the program of lifting and lining the screw can be canceled, which is good for curing, prolongs the service life of the sleepers, and reduces the material consumption.

Description

Detachable slide plate

The utility model relates to the slide plate that the wooden railroad crosstie changing points partly uses.

Public railroad switch sliding bed, it is monolithic construction, be fixed on the sleeper with square head screw, the slide plate of this device is when carrying out the gauge adjustment, also need screw is extracted, make the maintenance activity difficulty, the frequent operation of changing its course, often squeeze into or extract screw and be easy to make the nail hole rotten, damage sleeper.

The purpose of this utility model is to propose a kind of breakdown slide plate, makes it connect and to help the line maintenance operation with the ω elastic bar fastener, prolongs the application life of sleeper and other top-out.

Utility model is achieved in that a kind of breakdown slide plate, form by slide plate and slide plate cover two parts, establish the slide plate groove in the slide plate cover, shoulder block and nylon seat are established in both sides, the sublingua of slide plate can embed or split out from sliding bed cover groove as required, and nylon seat also can embed or release as required.

The utlity model has following characteristics:

1, the slide plate cover is fixed on the sleeper, and the slide plate sublingua extend in the slide plate groove, does not need to turn screw when changing its course, as long as transposing nylon seat model, just can movable slide bed plate, and sleeper is without prejudice.

2, if when the plain edition tongue is replaced by AT type tongue, the slide plate in the middle of only needing to change, it is motionless still can to keep original slide plate cover, helps the ordinary maintenance operation, reduce cost, and convenient disassembly.

Fig. 2: one of slide plate embodiment-AT tongue

Fig. 3: two of slide plate embodiment-common tongue

Now further narrate the utility model in conjunction with the accompanying drawings

Referring to Fig. 1: establish slide plate groove 4 in the slide plate cover, can embed AT tongue or common tongue, 3 places are screwed on sleeper at the spill bolt hole, rely on shoulder block 1 that various model nylon seats 2 can be installed, the slide plate cover is fixed on track switch and goes up the turn-out track part, because railway spike is too little to the buckle press of rail, and float off inefficacy easily, be difficult to keep the geometry of track structure, adopt the utility model, help the operation of changing its course.Connect sleeper bolt hole 3, slide plate groove 4 connects ω spring secures rail to sleeper bolt hole 5.

Slide plate platform 7 one ends 10 that are suitable for referring to Fig. 2 A, B:AT tongue are near the rail flange of rail 12, slope 1:4, and other holds 11 to be connected stock rail by ω elastic bar fastener, gauge apron with the slide plate cover and to place on the slide plate 8, and slide plate sublingua 6 is embedded in slide plate and overlaps in 9.

Referring to Fig. 3 A, B: slide plate platform 7 one ends 10 that common tongue is suitable for overlap with slide plate by ω elastic bar fastener gauge apron and are connected, slope＜1:4, and thickness 13 is 6mm, radius R=4, slide plate 8 thickness 10mm, slide plate sublingua 6 thick 10mm are embedded in the slide plate cover 9.

Claims

1, a kind of breakdown slide plate, form by slide plate and slide plate cover two parts, feature of the present utility model is: establish slide plate groove 4 in the slide plate cover, shoulder block 1 and nylon seat 2 are established in both sides, the sublingua 6 of slide plate can embed or split out from slide plate cover groove 4 as required, and nylon seat 2 also can embed or release as required.
