Abstract

The utility model relates to a novel wheel guard rail device, which is a new safeguard on the railway line for safety assurance. The utility model is suitable for arranging on the rail sectors which need to arrange guard rails on the rails with concrete ties (including wide ties), solid beds and wooden ties, and the guard rail can be arranged simply. The utility model is composed of guard rails and guard rail support frames, wherein, the guard rail support frame is arm-shaped; one end of the guard rail support frame is provided with a bolt hole for arranging a buckle, the middle part of the guard rail support frame is provided with a groove for clamping the bottom of a stock rail, and the other end of the guard rail support frame is provided with guard rail clamping grooves and a supporting seat for fixing the guard rail; the support frame is fixed on the bottom of the stock rail by fasteners with the aid of pinch plates, and the guard rails is inserted into the clamping grooves and fixed on the support frame by the fasteners. The utility model has the advantages that the roll-over caused by the derailment can be prevented; the derailment of wheels can be prevented and the lateral abrasion of the rails can be reduced.

Description

Novel check rail device

The utility model relates to a kind of traffic safety protective equipment of railway track, is used for the security protection of location circuits such as bridge, tunnel, high embankment and curve.

Extensively use concrete sleeper (containing wide pillow) now on the China railways in a large number, on the circuit in locations such as bridge, tunnel for security protection, need to install the check rail device, the check rail device that past uses on sleeper, be on sleeper, check rail to be followed closely solid inboard at rail with railway spike with check rail, and the spacing between check rail and the basic rail head inboard is bigger, is difficult to arrange.This check rail structure has been unsuitable for being used on the circuit of concrete sleeper.

The purpose of this utility model is the shortcoming that overcomes above-mentioned technology, provide a kind of not with the novel check rail device of sleeper generation annexation; On the circuit of ordinary concrete sleeper, broad tie, solid concrete roabed and wooden sleeper, all can install and use.

The technical solution of the utility model is to realize like this, this novel check rail device is made up of check rail and check rail bracing frame, the check rail bracing frame is an arm shape, one end is provided with the bolt hole that buckle is installed, there is card stock rail kerve the centre, the other end is provided with the check rail draw-in groove and installs and fixes the bolt bearing of check rail, and bolt hole is arranged on bearing; Be lined with the buffer insulation adjusting pad between card flange of rail groove and the rail foot,, by buckle the check rail bracing frame withheld firmly on the stock rail flange of rail of a side, between the buckle and the flange of rail, be lined with the buffer insulation adjusting pad with securing members such as bolt, nut, packing rings; One side iron chains of check rail are gone in the check rail draw-in groove, and another side is fixed on check rail on the bearing of bracing frame by fixing check rail bolt; The check rail bracing frame is installed on the stock rail flange of rail between adjacent two sleepers at regular intervals, check rail not with sleeper generation annexation.As required, can check rail be set in the inboard of two or one stock rails of track.

The utility model advantage compared with prior art is: check rail not with sleeper generation annexation; It both can prevent to overturn after the derail; Can prevent the train wheel derailing again; Also can reduce the abrasion of rail head side direction.And can on ordinary concrete sleeper, broad tie and ballastless track, install and use; And cost is lower, and installing/dismounting is all easier.

Now describe the utility model most preferred embodiment in conjunction with the accompanying drawings in detail;

Fig. 1 is the structural representation of novel check rail device.

Fig. 2 is novel to install and use figure on the line for the check rail device.

A kind of general novel check rail device as shown in Figure 1, it is by check rail 2 (available angle steel, light rail or old rail are made) and check rail bracing frame 1 form: check rail bracing frame 1 is an arm shape, one end is provided with the bolt hole 7 that buckle is installed, there is card stock rail flange of rail groove 8 centre, the other end is provided with check rail draw-in groove 9 and installs and fixes the bolt carrier base 10 of check rail, bolt hole 11 is arranged on bearing 10, be lined with buffer insulation adjusting pad 4 between card flange of rail groove 8 and stock rail 12 bottoms, use bolt, nut, packing ring securing member 6 is withheld check rail bracing frame 1 by buckle 5 and is fastened on stock rail 12 flanges of rail, between the buckle 5 and the flange of rail, be lined with buffer insulation adjusting pad 4, check rail 2 is an angle steel, be bumped in the check rail draw-in groove 9 on one side, another side by fixing check rail bolt 3 check rail 2, be fixed on the check rail bracing frame 1, check rail bracing frame 1 is installed on the flange of rail of stock rail of 13 of adjacent two sleepers as shown in Figure 2 at regular intervals, in the inboard of two or one stock rails 12 of track check rail 2 is set.

Check rail bracing frame 1 can forge or casting with pressing mold, its check rail 2 can adopt angle steel with sufficient intensity and rigidity or suitable rail material (as light rail or old rail), spacing size between check rail 2 and the stock rail 12 (being width of flangeway), should require difference according to function, can in the 60-200mm scope, design to select by actual needs and decide check rail.The two ends of check rail, the spacing between its check rail 2 and the stock rail 12 is generally 110-200mm, and its length should be less than 375mm.

Novel check rail device is divided into safe check rail device, anti-off-line check rail device and its range of application of anti-attrition check rail device by the difference of its function requirement:

1, safe check rail device

Should spread safe check rail device in following situation:

(1) on grand bridge and the big jackshaft;

(2) on long 10m of bridge and the above foot bridge, when sweep is less than or equal to 600m or bridge height (flange of rail is to the riverbed lowest part) greater than 6m;

(3) cross on the overpass bridge on railway, important highway, urban traffic thoroughfare;

(4) each line on the multiple-track bridge; High embankment location, mountain area;

(5) on the track under the overpass bridge, pillar from orbit centre to overpass bridge distance is during less than 3.0m;

(6) in each 5m scope of curb retaining wall and two ends thereof, rise out ground 6m, wall location when wall and be the steep bank of steep cliff or lateral slope of ground hillside down, and continuous length is during greater than 20m greater than 1: 0.75, should be at one-sided laying check rail device;

(7) in the paved crosing width range.

2, anti-off-line check rail device

Before and after sharp radius curve, long steep grade knick point and on the track in location such as long tunnel, anti-off-line check rail device should be set, with the prevention train wheel by the time derailing slide down.

3, anti-attrition check rail device

As one of anti-attrition measure, can be at following strand of rail installed inside anti-attrition check rail device of the mountain railway sharp radius curve track that wears away especially severe, as the side direction abrasion that alleviate curve silent partners rail head of rail.Also can anti-attrition check rail device be installed, to reduce the wearing and tearing of tongue at the suitable position of turnout switch tongue.
