Abstract
The utility model belongs to the technical field of turnouts, particularly relates to a turnout applicable to low-floor vehicles and solves the problem of the probability of derailing of low-floor vehicles when the low-floor vehicles pass through standard turnouts. The turnout comprises a main rail and a protection rail and is characterized in that an L-shaped cover plate is arranged on the protection rail, the tail end of the L-shaped cover plate is welded on a transmission shaft, and a snapping groove capable of snapping the lower edge of the protection rail head is formed in the front end of the L-shaped cover plate. The transmission shaft is mounted on two shaft sleeves in a rotatable mode, the shaft sleeves are welded on a rail support on the inner side of the protection rail, and a detachable spanner is arranged on the transmission shaft. The turnout has the advantages of being short in transformation period, low in transmission cost, good in economy, simple and convenient to operate actually, good in stability and safety, not prone to damage and the like.
Description
Technical field
The utility model belongs to the technical field of track switch, is specifically related to a kind of track switch that is applicable to low floor vehicle.
Background technology
Low floor vehicle has the possibility of derailing when by standard points, the parameter comparison of two kinds of wheel of vehicle:
two kinds of wheel parameters that vehicle is corresponding
| Type of vehicle | Interior wheelspan mm | Wheel rim mm | Wheel thickness mm | Wheel diameter mm |
| Low floor vehicle | 1386±1 | 20.5 | 115±1 | 520 |
| Common vehicle | 1371±1 | 32 | 135 +1 | 840 |
Low floor vehicle, because wheel rim is than the short 11.5mm of the rim size of common wheel, causes taking turns outer to guard rail gap and increases to 21.5mm, exceedes national standard 10mm, causes vehicle when by frog (idle space), to have the possibility of derailing.
Summary of the invention
The utility model has the problem of derailing possibility when by standard points in order to solve low floor vehicle, a kind of track switch that is applicable to low floor vehicle is provided.
The utility model adopts following technical scheme to realize:
A kind of track switch that is applicable to low floor vehicle, comprise backbone and guard rail, it is characterized in that being provided with on guard rail L-type cover plate, L-type cover plate tail end is welded on power transmission shaft, L-type cover forward end arranges the draw-in groove that can block edge under guard rail rail head, power transmission shaft is rotatably installed on two axle sleeves, and axle sleeve is welded on the rail brace of guard rail inner side, and dismountable spanner is also installed on power transmission shaft.
The utlity model has following beneficial effect: short, the low good economy performance of improvement expenses of transformation cycle, practical operation are simple and convenient, stability and safety good, not fragile etc.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the schematic diagram of L-type cover plate,
In figure: 1-backbone, 2-guard rail, 3-L type cover plate, 4-power transmission shaft, 5-rail brace.
Detailed description of the invention
By reference to the accompanying drawings detailed description of the invention of the present utility model is described further.
Be the excesssive gap of low-floor wheel outer to guard rail for the reason that may cause low floor vehicle derailing, the utility model employing measure reduces this gap, prevents from when low floor vehicle from passing through frog derailing.
Be applicable to the track switch of low floor vehicle, comprise backbone 1 and guard rail 2, on guard rail 2, be provided with L-type cover plate 3, L-type cover plate 3 tail ends are welded on power transmission shaft 4, L-type cover plate 3 front end settings can be blocked the draw-in groove on edge under guard rail 2 rail heads, and power transmission shaft 4 is rotatably installed on two axle sleeves, and axle sleeve is welded on the rail brace 5 of guard rail inner side, dismountable spanner is also installed on power transmission shaft 4, realizes the open and close of L-type cover plate.
Regulate the distance between backbone and guard rail by mobilizable L-type cover plate, in the time that common vehicle is passed through track switch, L-type cover plate is opened, and gap is 42mm; In the time that low floor vehicle passes through track switch, L-type cover plate closing, gap becomes 30mm.
