[0001] The utility model relates to the technical field of railway track maintenance, and particularly to an insulating pad. Background Art

[0002] The insulating pad under the rail refers to a cushion plate made of rubber or plastic and arranged between the rail and the concrete sub - rail components to play an insulating and shock - absorbing role, making up for the deficiencies of concrete rigid materials. The insulating pad under the rail is applied under the rail, and its main functions are to buffer the high - speed impact vibration generated when the vehicle passes through the rail, protect the roadbed and sleepers, and provide electrical insulation for the railway signal system.

[0003] Chinese Patent No. CN221235830U discloses a structure of an insulating pad under the rail for a rail insulating fastener. It has umbrella - skirt - type insulating sections arranged on the pad body, which is easy to construct and has moisture - proof and pollution - proof capabilities. However, since the structure of the insulating pad under the rail is outdoors for a long time, exposed to wind, rain, and in contact with the rail, the position in contact with the rail will undergo certain deformation and produce depressions, thus accumulating rainwater and causing the rail to rust. Summary of the Utility Model

[0004] The utility model provides an insulating pad. By arranging anti - slip ribs on the upper and lower surfaces of the insulating pad, the frictional force between it and the rail and the sleeper is increased, and the rainwater accumulated on the insulating pad can be discharged through the anti - slip ribs and multiple water guide grooves on the side, avoiding the rail from rusting.

[0005] The utility model provides an insulating pad, which includes a top surface, a bottom surface, two relatively - arranged first side surfaces and two relatively - arranged second side surfaces. The top surface and the bottom surface are both rectangular, and the area of the bottom surface is larger than that of the top surface. Multiple anti - slip ribs are convexly arranged on both the top surface and the bottom surface, and multiple water guide grooves are opened on both the first side surface and the second side surface. The two ends of the water guide groove extend to the edge of the top surface and the edge of the bottom surface respectively.

[0006] In one embodiment, at least two anti - slip ribs on the top surface are arranged in both the length direction and the width direction of the top surface, and each anti - slip rib is spaced apart and parallel to each other.

[0007] In one embodiment, at least two anti - slip ribs on the bottom surface are arranged in both the length direction and the width direction of the bottom surface, and each anti - slip rib is spaced apart and parallel to each other.

[0008] In one embodiment, the first side surface includes a first inclined surface and a first vertical surface connected to each other, and the top of the first vertical surface is connected to the bottom of the first inclined surface.

[0009] In one embodiment, the second side surface includes a second inclined surface and a second vertical surface connected to each other, and the top of the second vertical surface is connected to the bottom of the second inclined surface.

[0010] In one embodiment, the plurality of water guide grooves on the first side are arranged at equal intervals, and the plurality of water guide grooves on the second side are arranged at equal intervals.

[0011] In one embodiment, the device comprises an outer cladding layer, an insulating layer, a connecting layer and a buffer layer arranged in sequence from the outside to the inside, wherein the connecting layer is arranged on both sides of the buffer layer, and the insulating layer is arranged between the outer cladding layer and the connecting layer.

[0012] In one embodiment, a plurality of first grooves are provided on both sides of the buffer layer, a plurality of first protrusions are provided on both sides of the connecting layer, a plurality of second grooves are provided on both sides of the insulating layer, and a plurality of second protrusions are provided on the inner side of the outer covering layer. The first protrusions can be inserted into the first grooves or the second grooves, and the second protrusions can be inserted into the second grooves.

[0013] In one embodiment, the first protrusions on both sides of the connection layer are arranged in a staggered manner, and the second grooves on both sides of the insulation layer are arranged in a staggered manner.

[0014] In one embodiment, the outer covering layer, the insulating layer and the connecting layer are made of rubber, silicone and plastic respectively.

[0015] Compared with the existing technology, the advantages of the present invention are that the anti-skid ribs provided on the top and bottom surfaces not only enhance friction, but the gaps between the ribs also provide a certain degree of drainage. Water on the top surface can be smoothly drained along the water guide grooves on the first or second side surfaces, preventing water accumulation on the top surface from corroding the rails. Because the bottom surface area is larger than the top surface area, the insulating pad of the present invention can provide stable and reliable support for the rails.

Detailed implementation manners

[0023] The present utility model will be further described below with reference to the accompanying drawings.

[0024] As Figure 1 and Figure 2 shown, an insulating pad according to an embodiment of the present utility model includes a top surface 11, a bottom surface 12, two relatively arranged first side surfaces 13 and two relatively arranged second side surfaces 14. Both the top surface 11 and the bottom surface 12 are rectangular, and the area of the bottom surface 12 is larger than that of the top surface 11. A plurality of anti-slip ribs 2 are convexly provided on both the top surface 11 and the bottom surface 12. A plurality of water guide grooves 15 are provided on both the first side surface 13 and the second side surface 14. Both ends of the water guide groove 15 extend to the edge of the top surface 11 and the edge of the bottom surface 12 respectively.

[0025] The anti-slip ribs 2 provided on the top surface 11 and the bottom surface 12 can not only enhance the friction force, but also the gaps between the anti-slip ribs 2 can play a certain role in draining water. The water on the top surface 11 can be smoothly discharged along the water guide grooves 15 on the first side surface 13 or the second side surface 14, avoiding the corrosion of the rail caused by water accumulation on the top of the insulating pad. Since the area of the bottom surface 12 is larger than that of the top surface 11, the insulating pad of the present utility model can provide stable and reliable support for the rail.

[0026] As Figure 1 shown, there are two anti-slip ribs 2 on the top surface 11 in the length direction of the top surface 11 and four in the width direction, and the anti-slip ribs 2 are spaced apart from each other and parallel. Setting a larger number of anti-slip ribs 2 can achieve a better anti-slip effect. The anti-slip ribs 2 are spaced apart from each other and parallel, so that a smooth water drainage channel can be formed on the top surface 11, facilitating the drainage of water.

[0027] In this embodiment, the anti-slip ribs 2 occupy most of the area of the top surface 11, enabling the anti-slip ribs 2 to fully contact the rail to achieve a better anti-slip effect.

[0028] As Figure 2As shown, the anti-slip ribs 2 on the bottom surface 12 are arranged in the same manner as the anti-slip ribs 2 on the top surface 11. There are two anti-slip ribs in the length direction of the bottom surface 12 and four anti-slip ribs in the width direction, and each anti-slip rib 2 is spaced apart and parallel to each other.

[0029] In this embodiment, the anti-skid ribs 2 occupy most of the area of the bottom surface 12, so that the anti-skid ribs 2 can fully contact the sleepers or the roadbed to achieve a better anti-skid effect.

[0030] like Figure 1 As shown, the first side surface 13 includes a first inclined surface 131 and a first vertical surface 132 connected to each other, with the top of the first vertical surface 132 connected to the bottom of the first inclined surface 131. The second side surface 14 includes a second inclined surface 141 and a second vertical surface 142 connected to each other, with the top of the second vertical surface 142 connected to the bottom of the second inclined surface 141. The portions of the first and second side surfaces 13 and 14 of the insulating pad near the bottom surface 12 are both vertical planes. This prevents the bottom of the insulating pad from deforming when the insulating pad is under pressure, thus providing good support.

[0031] like Figure 1 As shown, the plurality of water guide grooves 15 on the first side 13 are arranged at equal intervals, and the plurality of water guide grooves 15 on the second side 14 are arranged at equal intervals. The water guide grooves 15 are evenly distributed and linear on both the first side 13 and the second side 14, so that water can be drained smoothly from all locations on the top surface 11.

[0032] like Figure 3 As shown, the insulating pad includes an outer covering layer 3, an insulating layer 4, a connecting layer 5, and a buffer layer 6, which are arranged in sequence from the outside to the inside. The connecting layer 5 is arranged on both sides of the buffer layer 6, and the insulating layer 4 is arranged between the outer covering layer 3 and the connecting layer 5. By arranging the insulating layer 4, the connecting layer 5, and the buffer layer 6 inside the outer covering layer 3, the outer covering layer 3 can be supported from the inside, thereby ensuring that the outer covering 3 can be used for a longer time. In addition, by using the insulating layer 4 and the connecting layer 5 of various materials inside the outer covering 3, more effective insulation can be achieved.

[0033] like Figure 4As shown in the figure, a plurality of first grooves 61 are provided on both sides of the buffer layer 6, a plurality of first protrusions 51 are provided on both sides of the connection layer 5, a plurality of second grooves 41 are provided on both sides of the insulating layer 4, and a plurality of second protrusions 31 are provided on the inner side of the outer wrapping layer 3. The first protrusions 51 can be snapped into the first grooves 61 or the second grooves 41, and the second protrusions 31 can be snapped into the second grooves 41. By setting the outer wrapping layer 3, the insulating layer 4, the connection layer 5 and the buffer layer 6 into the above structures, it is not only convenient for the assembly between the layer structures, but also the connection is tighter. When the insulating pad is pressed, relative displacement is not likely to occur between the layer structures, thereby improving the bearing capacity and stability of the insulating pad and prolonging the service life of the insulating pad.

[0034] Furthermore, the first protrusions 51 on both sides of the connection layer 5 are arranged staggeredly, and the second grooves 41 on both sides of the insulating layer 4 are arranged staggeredly, so that the thinnest parts of the connection layer 5 and the insulating layer 4 still have a relatively large thickness, which is beneficial to improving the anti-deformation ability and service life of the connection layer 5 and the insulating layer 4.

[0035] In this embodiment, since the buffer layer 6 has a relatively large thickness, the first grooves 61 on both sides of the buffer layer 6 may not be opened in a staggered manner.

[0036] In this embodiment, the outer wrapping layer 3, the insulating layer 4 and the connection layer 5 are made of rubber, silica gel and plastic respectively, and the buffer layer 6 is a microcellular foaming material. The insulating pad is made of such a composite material, and its comprehensive performance is better than that of the insulating pad made of a single rubber material conventionally.

[0037] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
