DETAILED DESCRIPTION

[0020] The above and other embodiments and advantages of the present application will be more clearly understood from the following description taken in conjunction with the accompanying drawings, in which:

[0021] In an embodiment, as Figures 1-7 shown.

[0022] The railway integral crossing plate convenient to maintain provided by the embodiment comprises a pouring block 1, a middle plate 2 fixed on the top of the pouring block 1 through prefabricated screws, side plates 3 fixed on the top of the pouring block 1 and distributed on both sides of the middle plate 2 through prefabricated screws, a steel rail 4 clamped between the two side plates 3 and the middle plate 2, flange grooves 5 opened on both sides of the middle plate 2 and facing the inner side surface of the steel rail 4, one end of the flange groove 5 extending to one end of the middle plate 2, the other end of the flange groove 5 extending to the other end of the middle plate 2, two support plates 6 fixed at the end of the middle plate 2, the support plates 6 corresponding in the straight line direction of the flange groove 5, a limiting plate 7 fixed on the top surface of the support plate 6, the inner side surface of the limiting plate 7 flush with the inner side surface of the flange groove 5, a cleaning plate 8 provided between the limiting plate 7 and the steel rail 4 and laid on the top surface of the support plate 6, and the top surface of the cleaning plate 8 flush with the flange groove 5.

[0023] In the embodiment, the train wheel is located in the two wheel flange grooves 5, so once the impurities such as sand in the railway environment fall into the wheel flange groove 5, it will cause the wheel to bump on the sand when it travels along the wheel flange groove 5. According to the characteristics of the train wheel, the wheel flange groove 5 is often narrow and deep, so in the embodiment, once the impurities such as waste fall into the wheel flange groove 5, the cleaning plate 8 can be pulled into the wheel flange groove 5, and the cleaning plate 8 is pulled from one end to the other end of the wheel flange groove 5, that is, from one end to the other end of the middle plate 2. The thickness of the cleaning plate 8 is smaller than the groove depth of the wheel flange groove 5, and the width of the cleaning plate 8 is smaller than the groove width of the wheel flange groove 5, so the cleaning plate 8 can be smoothly pulled from one end to the other end of the wheel flange groove 5 while completely cleaning the impurities in the wheel flange groove 5. After use, the cleaning plate 8 can be pushed back to the support plate 6 in the opposite direction, and when the cleaning plate 8 is retracted to the support plate 6, the top surface of the support plate 6 is lower than the bottom of the wheel flange groove 5, and at this time the top surface of the cleaning plate 8 is flush with the bottom of the wheel flange groove 5, that is, the cleaning plate 8 is repositioned to the support plate 6 and is supported by the support plate 6 and limited by the limiting plate 7 to prevent falling off. In addition, it can also ensure that the train wheel rolls along the wheel flange groove 5 without being affected by the top surface of the cleaning plate 8.

[0024] In a specific design, as shown in Figure 7 , a sleeve can be pre-buried on the pouring block 1 to facilitate subsequent construction.

[0025] In another embodiment, as shown in Figure 3 , Figure 4 and Figure 6 , an active gap 11 is left between the top surface of the cleaning plate 8 and the top surface of the rail 4. A rounded corner 9 is provided at the bottom of one end of the wheel flange groove 5 close to the cleaning plate 8. A chamfer 10 opposite to the rounded corner 9 is provided at the top of one end of the wheel flange groove 5 close to the cleaning plate 8. A hinge seat 13 is provided at one end of the cleaning plate 8 close to the wheel flange groove 5. A steel bar 14 is hung on the hinge seat 13. The steel bar 14 extends along the wheel flange groove 5 to the other end of the middle plate 2, and a pull rod 15 is connected at the end of the steel bar 14.

[0026] In the embodiment, one end of the cleaning plate 8 is connected with the reinforcing rod 14 through the hinge seat 13, and the reinforcing rod 14 is provided with the pull rod 15 extending to the other end of the middle plate 2 along the rim groove 5. Therefore, when the operator holds the pull rod 15 and pulls the pull rod 15 towards the end of the middle plate 2, the reinforcing rod 14 will be displaced synchronously with the pull rod 15, and the reinforcing rod 14 will pull the cleaning plate 8 through the hinge seat 13 at the other end of the reinforcing rod 14. Since the cleaning plate 8 is connected to the hinge seat 13 and is located on the supporting plate 6 when the cleaning plate 8 is not in action, the cleaning plate 8 will be in contact with the chamfer 10 of the rim groove 5 when the cleaning plate 8 is pulled, and the chamfer 10 will be continuously pressed by the round corner 9 during the continuous pulling process, so that the cleaning plate 8 is rotated around the hinge seat 13 into the rim groove 5, and finally the cleaning plate 8 is pulled into the rim groove 5, and the cleaning plate 8 is smoothly pulled from one end of the rim groove 5 to the other end of the rim groove 5 during the continuous pulling process, so that the impurities in the rim groove 5 are completely cleaned. Since the pulling rod 15 can be operated at the other end, the operation is convenient.

[0027] As shown in Figures 1 to 4 , the top surface of the middle plate 2 and the side plate 3 is provided with an upwardly protruding anti-skid cone 12, and the anti-skid cone 12 is in a cylindrical shape. When the ordinary vehicle passes through the middle plate 2 and the side plate 3 to travel on the road in the lateral direction, the anti-skid effect is achieved by rolling on the anti-skid cone 12.

[0028] As shown in Figure 2 , the middle plate 2 is provided with a receiving groove 16 at the other end away from the cleaning plate 8, and the pull rod 15 is clamped in the receiving groove 16. When the cleaning plate 8 is used, the operator holds the pull rod 15 and applies an outward pulling force, so that the pull rod 15 is pulled out of the receiving groove 16. During the continuous pulling process, the cleaning plate 8 is pulled into the rim groove 5 through the reinforcing rod 14. During the continuous pulling process, the cleaning plate 8 is smoothly pulled from one end of the rim groove 5 to the other end of the rim groove 5. After use, the pull rod 15 is pushed in the reverse direction, the pull rod 15 pushes the reinforcing rod 14 to move in the reverse direction, the reinforcing rod 14 pushes the hinge seat 13 to push the cleaning plate 8 to the supporting plate 6 again, so that the cleaning plate 8 is reset. At this time, the pull rod 15 is clamped into the receiving groove 16 again for reasonable storage, so that the pull rod 15 can be directly pulled out for use next time.

[0029] The above specific embodiments further illustrate the utility model purpose, technical scheme and beneficial effects of the utility model. It should be understood that the above description is only a specific embodiment of the utility model, and is not used to limit the protection scope of the utility model. It is particularly pointed out that any modification, equivalent replacement, improvement, etc. made by those skilled in the art within the spirit and principles of the utility model should be included in the protection scope of the utility model.
