Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a rail insulation pad used for the construction of railway line transverse beams. Background Art

[0002] With the continuous development of urban construction, the number of projects crossing railways is gradually increasing. In order not to interrupt train operation and ensure construction and driving safety, necessary online protection measures should be taken. Among them, construction such as underpasses of bridges and culverts and dark tunnel excavation often adopts the method of longitudinal and transverse beams + 3-5-3 track buckling for online protection. In this construction process, in addition to the safety hazards caused by the main construction, the line reinforcement construction process itself will also cause safety problems that affect driving. Among them, the more common problems and the greater impact are the line closure caused by the horizontal beam lifting.

[0003] In the past, the measure to prevent electrical connection during the operation of passing through the beam was to place a wooden board on the beam for protection. However, the strength of the wooden board is poor, it is easy to break, split, and crush, it is easy to fall off when passing through the beam, and it is very easy to be damaged under the pressure of the train load, so the effect of preventing electrical connection is not very ideal, and the construction consumption is large, and it is almost impossible to reuse it. Therefore, a wooden board substitute is urgently needed to improve or solve the above problems. Utility Model Content

Since the outer side grooves are arranged at intervals along the length direction of the edge limiting structure, corresponding reinforcing rib structures can be formed between adjacent outer side grooves. Therefore, although the structural strength of the edge limiting structure in the length direction is reduced, the influence of the connection strength of the buckling position is avoided by the formed reinforcing rib structure, and the buckling stability with the rail is ensured.

[0034] According to a scheme of the utility model, in the utility model, a linear groove is provided on the bottom support structure so as to reduce the contact area between the bottom support structure and the bottom surface of the rail, so that part of the space between the bottom support structure and the bottom surface of the rail can be connected with the external environment, thereby effectively eliminating the disadvantage of relative sliding caused by internal air accumulation and inability to be discharged when the bottom support structure and the bottom surface of the rail are in contact over a large area when the rail is subjected to changes in external loads, thereby effectively eliminating the disadvantage of relative sliding caused by internal air accumulation and inability to be discharged, thereby being beneficial to improving the support stability of the utility model.

In this embodiment, the bottom support structure 11 and the edge limiting structure 12 are arranged as one body. Of course, in another embodiment, the edge limiting structure 12 can be separately arranged on one side of the bottom support structure 11 in the width direction.

[0043] In this embodiment, a positioning structure 1a connected to the bottom edge of the rail is formed between the edge limiting structure 12 and the bottom support structure 11, and is used to limit the rail insulation pad at the bottom of the rail.

[0044] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the positioning structure 1a formed between the edge limiting structure 12 and the bottom support structure 11 can be configured as a covering groove for engaging with the bottom edge of the rail.

[0045] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the utility model, the edge limiting structure 12 includes: a supporting portion 121 and a pressing portion 122; wherein one end of the supporting portion 121 is fixedly connected to the edge of the bottom support structure 11, and the other end is fixedly connected to the pressing portion 122; in this embodiment, one end of the pressing portion 122 is connected to the supporting portion 121, and the other end extends in a direction away from the supporting portion 121, so as to form a covering groove between the edge limiting structure 12 and the bottom support structure 11. Specifically, when the edge limiting structure 12 is symmetrically arranged on both sides of the width direction of the bottom support structure 11, the pressing portions 122 of the symmetrically arranged edge limiting structure 12 extend in a direction close to each other, so as to form a covering groove between the edge limiting structure 12 and the bottom support structure 11, that is, a covering groove for engaging with the bottom edge of the rail can be formed between the supporting portion 121, the pressing portion 122 and the bottom support structure 11.

[0048] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the thickness of the bottom support structure 11 is smaller than the thickness of the pressing portion 122 .

[0049] Through the above arrangement, by setting the thickness of the bottom support structure 11 to be smaller than other structures, the strength of the bottom support structure 11 itself is reduced, and thus it can better adapt to the change in the interval between the bottom of the rail and the cross beam through its deformation, so that the installation and support of the utility model are stable and reliable. In addition, the bottom support structure 11 can provide better elastic support at the installation position by means of a smaller thickness, so that it has better shock absorption and anti-seismic effect.

Since the outer side grooves 12a are arranged at intervals along the length direction of the edge limiting structure 12, corresponding reinforcing rib structures can be formed between adjacent outer side grooves 12a, thereby, although the structural strength of the edge limiting structure 12 in the length direction is reduced, the influence of the connection strength of the buckling position is avoided by the formed reinforcing rib structure, and the buckling stability with the rail is ensured.
