Description
Technical Field
[0001] The utility model relates to a crossing pavement which can be quickly and conveniently laid at a railway crossing and belongs to the technical field of railway crossing facilities. Background Art
[0002] Railway crossings are important passages where railways and roads intersect. With the existence of railway crossings, pedestrians and vehicles on the road can cross the railway without being restricted by the railway tracks. Similarly, with the existence of railway crossings, trains can pass smoothly without being restricted by the roads and tracks when passing through the intersection with the road. The importance of railway crossings is self-evident. At present, no railway crossings are allowed on railways where high-speed trains pass, but some low-speed railways, factory-owned railways, and some temporary needs to pass ordinary railways can set up railway crossings according to the requirements of the terrain. At present, there are three ways to set up railway crossings that meet the requirements. The first is the most commonly used concrete integral railway crossing, but the concrete integral railway crossing has a long construction period. After the concrete is damaged, it affects the traffic safety of the railway and the highway. Once the concrete integral crossing is built, the intersection of the railway and the highway will become a whole and cannot be repaired. If you want to repair it, you have to demolish and rebuild it, and the construction requirements are high. The second is a crossing paved with wooden sleepers, but the crossing paved with wooden sleepers is not strong enough. The wooden sleepers are nailed to the sleepers of the track with spikes. They are easy to lift up after being rolled over by passing vehicles, causing major accidents when cars, trains and pedestrians pass through the crossing. In addition, the wooden sleepers are nailed to the sleepers of the track with spikes, which destroys the overall strength of the railway track and causes damage to the railway. Over time, it will cause safety hazards to railway driving; the third is a crossing paved with rubber sheets. The cost of laying this crossing is extremely high, and the construction period is long, which has a greater impact on railways and highways, and has high construction standards and requirements, and is difficult to maintain in the later stage.
[0003] In order to avoid the above shortcomings of existing railway crossings, speed up the construction of railway crossings, improve the strength of railway crossings, reduce the difficulty of laying railway crossings, and improve the maintenance efficiency of maintenance personnel, it is necessary to design a new railway crossing pavement.

[0022] The utility model is composed of a track middle pavement 1, a track side pavement 2 and bolts 6.
[0023] Figure 1 It is shown that the road surface of the crossing of the utility model is composed of a track center pavement 1 and two track side pavements 2. The track center pavement 1 and the track side pavements 2 are respectively rectangular parallelepipeds. The heights of the track center pavement 1 and the track side pavements 2 match the heights of the track, and the length of the track center pavement 1 matches the spacing between the two rails 10. Specifically, the gauge of the two rails 10 is the standard gauge of 1435mm, and the length of the track center pavement 1 is 1450mm, which is slightly larger than the standard gauge. The standard gauge is the distance between the inner sides of the rail heads of the two rails 10, and the distance between the rail beams at the bottom of the rail heads is larger than the standard gauge, so the two ends of the track center pavement 1 can be inserted under the rail heads of the rails 10. When in use, the track center pavement 1 is placed between the two rails of the track, and the two track side pavements are placed on the outsides of the two rails of the track, and the two track side pavements 2 are relatively in a straight line with the track center pavement 1. Pedestrians, cars and other vehicles can cross the track through the track pavement 1 and the track side pavement 2, while the track pavement 1 and the track side pavement 2 do not affect the passage of trains.
[0024] Figure 1 , 3 , 5, and 6 show that the lower parts of the track pavement 1 and the track side pavement 2 are provided with two raised bearing platforms 3, respectively. The width of the bearing platforms 3 matches the distance between the two sleepers 11 of the track, the height of the two bearing platforms 3 matches the height of the sleeper 11, the distance between the two bearing platforms 3 matches the width of the sleeper 11, and the distance from the outer sides of the two bearing platforms 3 to the edge of the pavement is 1 / 2 of the width of the sleeper 11. If two or more groups of track pavements 1 and track side pavements 2 are used to form a crossing pavement, the bearing platforms 3 on the outer sides of the adjacent track pavements 1 and track side pavements 2 are opposite, and the distance between the two opposite bearing platforms 3 is exactly equal to the width of one sleeper 11.
[0025] Figure 1 , 3 , 5, and 6 show that the track pavement 1 and the two track side pavements 2 are placed in the middle and on both sides of the two rails 10 of the track, respectively, and the bearing platform 3 at the bottom of the track pavement 1 and the two track side pavements 2 is embedded between the two sleepers 11, and the bearing platform 3 at the bottom of the track pavement 1 and the two track side pavements 2 is relatively in a straight line. The lower bottom surface of the bearing platform 3 is in contact with the roadbed, which can bear the pressure on the track pavement 1 and the track side pavement 2, and the bolts can connect the track pavement 1 and the track side pavement 2 as a whole through the bearing platform 3.
[0026] Figure 1 , 3, 5 and 6 show that the load-bearing platform 3 at the lower part of the track center pavement 1 is provided with threaded holes 4 along the length direction of the load-bearing platform 3, and the load-bearing platforms 3 at the lower part of the two track side pavements 2 are provided with connecting through holes 5 along the length direction of the load-bearing platform 3. Two groups of bolts 6 pass through the connecting through holes 5 of the load-bearing platform 3 from the outside of the two track side pavements 2 and are connected to the threaded holes 4 at both ends of the load-bearing platform 3 of the track center pavement 1. The bolts are between the two sleepers under the track.
[0027] Figure 1 , 2 6 shows that in order not to affect the wheel flanges of the train wheels running on the track, the upper parts of the two sides of the track pavement 1 opposite to the two rails 10 have gaps along the track direction, and the gaps are wheel flange grooves 7. The width of the wheel flange groove 7 is opposite to the outer side of the wheel flange of the railway vehicle on the rail 10, and the wheel flange is embedded in the wheel flange groove 7.
[0028] Figure 1 , 5 , 6, and 8 show that the upper parts of the two sides of the two track side pavements 2 opposite to the two rails 10 have gaps along the track direction, and the gaps are rail head slots 8. The height and width of the rail head slots 8 match the height and width of the rail head part of the rail 10, and the rail head of the rail 10 is embedded in the rail head slots 8.
[0029] Figure 1 , 5 , 6, and 8 show that the lower parts of the track center pavement 1 and the two track side pavements 2 opposite to the two rails 10 have gaps along the track direction, and the gaps are rail bottom slots 9. The height and width of the rail bottom slots 9 match the height and width of the rail bottom part of the rail 10, and the rail bottom of the rail 10 is embedded in the rail bottom slots 9.
[0030] The track middle pavement 1 and the track side pavement 2 of the utility model are respectively made of high-strength rubber casting, and the load-bearing platform 3, the threaded holes 4, the connecting through holes 5 are integrally cast with the track middle pavement 1 and the track side pavement 2. The threaded holes 4 are filled with metal turnbuckles, which are cast into the threaded holes 4 during casting.
[0031] The installation process of the utility model is as follows:
[0032] Since the length of the track pavement 1 is greater than the distance between the rail heads of the two rails 10, the track pavement 1 cannot be directly placed between the two rails 10. It is necessary to remove one rail 10, put the track pavement 1 in, and then restore the removed rail 10. The two ends of the track pavement 1 are inserted under the rail heads of the two rails 10. The load-bearing platform 3 at the lower part of the track pavement 1 can be placed in the gap between the two sleepers 11 with perfect fit. The wheel flange grooves 7 at the two ends of the upper part of the track pavement 1 are respectively opposite to the inner sides of the rail heads of the two rails 10, and the gap in the middle is the gap through which the wheel flange passes. The rail bottom slots 9 at the two ends of the lower part of the track pavement 1 are respectively relatively fitted with the inner rail bottoms of the two rails 10.
[0033] Then, the two track side pavings 2 are respectively installed on the outside of the two rails 10, and the bearing platform 3 at the bottom of the two track side pavings 2 can also be placed in the gap between the two sleepers 11 with perfect fit, and the rail head clamping grooves 8 at the top of the two track side pavings 2 are respectively relatively fitted with the outside of the rail heads of the two rails 10, and the rail head clamping grooves 8 at the bottom of the two track side pavings 2 are respectively relatively fitted with the outer rail bottoms of the two rails 10;
[0034] When installing the track side pavement 2, the connecting through hole 5 on the track side pavement 2 should be aligned with the threaded hole 4 on the track middle pavement 1 to facilitate the insertion of the bolt 6;
[0035] Finally, four bolts 6 are inserted into the connecting through holes 5 from the outside of the two track side pavements 2 and tightened to connect with the threaded holes 4 at both ends of the track middle pavement 1, so that the track middle pavement 1 and the two track side pavements 2 form a whole, and are firmly embedded with the railway rails and sleepers, so that a crossing road surface is formed on the upper part of the railway track that can pass cars and pedestrians.
[0036] The utility model can lay one or more groups of track middle pavement 1 and track side pavement 2 according to the need of laying a road crossing. If only a pedestrian crossing needs to be laid, only one or two groups need to be laid; if a motor vehicle crossing needs to be laid, six or eight groups need to be laid.
[0037] The utility model is strong, durable, simple in structure, and convenient for daily maintenance and replacement. It speeds up the construction of railway crossings, improves the strength of railway crossings, reduces the difficulty of laying railway crossings, improves the maintenance efficiency of maintenance personnel, and prevents damage to the original track part when laying railway crossings, thereby ensuring the safety and punctuality of train travel, ensuring smooth and safe highway travel, and meeting the needs of daily railway maintenance and replacement.
[0038] Compared with the existing concrete integral crossing, wooden sleeper paved crossing and rubber crossing, the utility model has the following advantages:
[0039] The cost of rubber crossings is extremely high, and the safety hazards of crossings paved with wooden sleepers are extremely high, which is far inferior to this project. Compared with this project, for a 12-meter-wide crossing, the material and construction costs of concrete crossings are about 40,000 yuan, and the construction time is 17 days. If it is dismantled and repaired, it will cost another 48,000 yuan. The material and construction costs of this project are 2,640 yuan, and the replacement of a single piece is 800 yuan. The damaged piece is replaced, and the installation only takes one day, which greatly saves maintenance costs.
[0040] Therefore, no matter from the pure cost or the time of laying, the economic benefit and social benefit of the utility model are far superior to the existing three crossings.
[0041] An embodiment of the present utility model is as follows:
[0042] The length of the track pavement 1 is 1450 mm, the width is 1000 mm, and the height is 520 mm. The width of the wheel flange groove 7 is 100 mm, and the height is 60 mm. The width of the rail bottom slot 9 is 90 mm, and the height is 30 mm.
[0043] The track side pavement 2 has a length of 480 mm, a width of 1000 mm, and a height of 520 mm. The rail head slot 8 has a width of 26 mm and a height of 50 mm. The rail bottom slot 9 has a width of 90 mm and a height of 30 mm.
[0044] The width of the load-bearing platform 3 is 280 mm, the height is 160 mm, the length of the gap between the two load-bearing platforms 3 is 220 mm, and the distance from both sides of the two load-bearing platforms 3 to the edge of the pavement is 110 mm;
[0045] The threaded holes 4 at both ends of the load-bearing platform 3 of the track mid-surface 1 are 32 mm threaded holes;
[0046] The connecting through hole 5 of the load-bearing platform 3 of the track side pavement 2 is a through hole with a diameter of 34 mm;
[0047] Bolt 6 is a bolt with a diameter of 32 mm;
[0048] Rail 10 is a standard rail;
[0049] The width of the sleeper 11 is 220 mm and the height is 160 mm.
