Description

Technical Field

[0001] The utility model relates to the technical field of integral crossing plates, and more specifically, to an integral crossing plate used for connecting railways and highways with large height differences at railway level crossings. Background Art

[0002] Crossing plates are suitable for railway and highway level crossings, urban light rail circular line level crossings, as well as station platforms, station luggage car aisles, freight yards, and dedicated lines inside and outside vehicle depot maintenance workshops, and dedicated railway and highway level crossings for enterprises and mines. Crossing plates connect railway and highway level crossings and can ensure the safe passage of passing vehicles and pedestrians.

[0003] When the road and railway intersection is located at the turning point of the railway, in order to overcome the centrifugal force of the train, the crossing plate adopts a structure with a lower inner side and a higher outer side of the turning radius, such as the reinforced concrete integral crossing plate in the circular curve section disclosed in the patent document with the announcement number CN203270400U. Figure 1 and 2 As shown, when one side of the integral crossing plate is flush with the road height, there will be a large height difference between the other side of the integral crossing plate and the road surface. Under the same slope requirements, it is necessary to increase the length of the connecting slope of the road connection, thereby increasing the construction period and construction cost.

[0004] In addition, when there are two railway lines running in parallel, the traditional integral crossing plate will also cause the slope of the connecting part between the two railway lines to be too steep, such as Figure 3 As shown in the figure, the distance between the two railway lines needs to be increased to reduce the slope of the connecting slope, resulting in an increase in the area occupied by the railway line, or as ... Figure 4 As shown in the figure, the crossing plates of the two railway lines are laid with one high and one low, and slope treatment is carried out at the junction of the highway on both sides of the railway. This not only increases the construction difficulty of the crossing plates, but also slopes on both sides, which increases the construction cost and implementation period.

[0005] Therefore, there is an urgent need for an integral crossing plate that can reduce the height difference between railways and highways and the length of the connecting slope, so as to reduce construction costs and shorten the construction period. Utility Model Content

[0006] The utility model provides an integral crossing plate for connecting railways and highways with large height differences at railway level crossings, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A monolithic crossing plate for connecting railways and highways at level crossings with large elevation differences comprises a crossing plate body having a first track groove and a second track groove, sequentially arranged from the inner side of a turning radius to the outer side. The top surface of the crossing plate body has a downward slope facing the highway connection direction outside the turning radius of the second track groove, and / or an upward slope facing the highway connection direction inside the turning radius of the first track groove. This reduces and avoids elevation differences between the railway and highway, as well as between two railway lines, shortening the length of the connecting slope and avoiding slope reduction, thereby reducing construction difficulty and cost, and shortening the implementation period.

[0009] As a further preferred solution, anti-slip guard plates are provided on both sides of the first track groove and the second track groove on the crossing plate body.

[0010] The anti-slip guard plate is preferably a detachable structure to facilitate replacement and maintenance of the anti-slip guard plate.

[0011] The crossing plate body is provided with mounting base plates on both sides of the first track groove and the second track groove, and the anti-slip guard plate is mounted on the mounting base plates.

[0012] The mounting seat plate is integrally cast on the crossing plate body, and an L-shaped sliding groove is provided on the mounting seat plate. A sliding block corresponding to the L-shaped sliding groove is provided on the anti-slip guard plate. The anti-slip guard plate can be quickly installed and disassembled by cooperating with the sliding block and the L-shaped sliding groove.

[0013] The mounting base plate is provided with threaded holes, the anti-skid guard plate is provided with corresponding countersunk holes, and the anti-skid guard plate is connected and fixed to the mounting base plate by countersunk bolts.

[0014] Compared with the existing turning track plates, the utility model effectively reduces and avoids the height difference between the connection between the railway and the highway and between the two railway lines through the design of the slope structure, shortens or even avoids the connection slope, reduces the construction difficulty and cost, and shortens the implementation period. In addition, the anti-skid guard plates protect the height and low point positions on both sides of the track groove, which can increase the service life of the crossing plates. The anti-skid guard plates are easy to install and disassemble, and are convenient for timely replacement and maintenance after wear.

[0015] The utility model has the characteristics of simple structure, strong practicability and good use effect, and is worthy of being widely promoted and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See Figure 5 and 6 , an integral crossing plate for connecting railways and highways with large height differences at railway level crossings, comprising a crossing plate body 1, with a first track groove 2 and a second track groove 3 arranged on the crossing plate body from the inner side to the outer side of the turning radius, rails 4 being pressed into the two track grooves by spikes 6 and fasteners 5, and protective pads 4 adapted to the track grooves being arranged on both sides of the rails 4 to prevent dust and gravel from entering the fasteners and to protect the stable connection between the fasteners 5 and the rails 4, the protective pads 4 being connected and fixed to the spikes 6, and the top surface of the protective pads 4 being flat, making it easy to clean and maintain.

[0029] The top surface of the crossing plate body 1 is provided with a downward slope 7 facing the road connection direction outside the turning radius of the second track groove 3. Figure 6 By designing the upslope surface 7 of the crossing plate, under the same slope requirements, the slope length of the connecting slope 9 at the junction of the crossing plate and the highway can be effectively reduced, thereby reducing construction costs and shortening the implementation period.

[0030] Connecting ribs 8 are pre-buried on both sides of the crossing plate body 1 to improve the strength of the connection between the entire crossing plate and the road and to improve the stability of the crossing plate. Example

[0031] See Figure 7-9 The difference between this embodiment and the first embodiment is that the top surface of the crossing plate body 1 has a downward slope 7 on the outer side of the turning radius of the second track groove 3 facing the road connection direction, and has an upward slope 10 on the inner side of the turning radius of the first track groove 2 facing the road connection direction. Through the cooperation of the downward slope 7 and the upward slope 10 on both sides of the turning radius, see Figure 8 , so that the height of both sides of the crossing plate is consistent with that of the road, thus avoiding the need for connecting slopes. Figure 9 By coordinating the slopes of the two crossing plates between the two railway lines, the height difference between the two crossing plates is reduced, the distance between the two railway lines is reduced, the problem of the railway lines occupying a large area is avoided, and the inconvenience of leveling the crossing plates of the two lines, such as one high and the other low, is avoided. The construction difficulty is reduced, the construction efficiency is improved, thereby effectively reducing costs and shortening the implementation period. Example

[0032] See Figure 10 and 11, the difference between this embodiment and embodiment one or two is that: the road crossing plate body 1 is provided with anti-skid guard plates 11 on both sides of the first track groove 2 and the second track groove 3 to protect the high and low points of the road crossing plate, and the anti-skid guard plates 11 are provided with anti-skid protrusions. This embodiment adopts the preferred scheme example, and the anti-skid guard plates 11 are detachable structures. Specifically, the road crossing plate body 1 is provided with mounting seat plates 12 integrally cast on the road crossing plate body 1 on both sides of the first track groove 2 and the second track groove 3. In this embodiment, the mounting seat plate 12 and the anti-skid guard plates 11 both adopt L-shaped structures. The mounting seat plate 12 can also be connected to the steel frame of the road crossing plate body 1 by connecting plates or connecting ribs to improve its connection strength. The mounting seat plate 12 is cast on the road crossing plate body 1 to form a connection with the anti-skid guard plates on both sides of the track groove. The sliding card block 13 is matched with the sliding card slot 13, and the mounting base plate 12 is provided with an L-shaped sliding card slot 13 and a threaded hole 14. In this embodiment, the sliding card slot 13 adopts a T-shaped cross-section structure, and the openings of the sliding card slot 13 are located on both sides of the track groove. The anti-slip guard plate 11 is provided with a sliding card block (not shown in the figure) corresponding to the sliding card slot 13 and a countersunk hole 15 corresponding to the threaded hole 14. When installing the anti-slip guard plate 11, the sliding card block is slid into the sliding card slot 13, and when it slides into the L-shaped bend of the sliding card slot 13, it slides into the sliding card slot 13 again along the length direction of the anti-slip guard plate 11, so that the anti-slip guard plate 11 and the mounting base plate 12 are snapped into place, and the countersunk bolt passes through the countersunk hole 15 and is threadedly connected to the threaded hole 14, so as to achieve a reliable connection between the anti-slip guard plate 11 and the mounting base plate 12.

[0033] When disassembling, first remove the bolts, then slide the anti-skid guard plate 11 in the opposite direction, and then you can remove and replace it for maintenance.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
