Description
Technical Field
[0001] This utility model relates to the field of railway track joint technology, specifically to an insulated non-standard joint. Background Technology
[0002] Insulating rail joints are rail joints that isolate the electrical circuit between rails. Specifically, insulating materials are used to insulate the rail clamps, bolts, two rails, and the rail ends of a standard rail joint. Currently, insulating rail joints are used for butt joints of the same type of rail, such as P60 rails with P60 rails, or P50 rails with P50 rails. When it is necessary to butt two different types of rails (e.g., P43 rails with P50 rails), there is no insulating joint available that allows both butt joints and insulation between the rail ends. Therefore, there is an urgent need for a special-shaped insulating joint to solve this problem. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] like Figures 1-7 As shown in Embodiment 1, an insulating non-standard joint includes an insulating part and two clamping plates 1. The two clamping plates 1 are symmetrically arranged on both sides of a first rail 5 and a second rail 6 that are connected. The height of the first rail 5 is less than the height of the second rail 6. The insulating part includes a first insulating gasket 2, two second insulating gaskets 3, and a third insulating gasket 4. The first insulating gasket 2 is disposed between the end faces of the first rail 5 and the second rail 6 that are connected. Each second insulating gasket 3 is disposed between a clamping plate 1 and a first rail 5, and each third insulating gasket 4 is disposed between a clamping plate 1 and a second rail 6. The height of the first insulating gasket 2 is greater than the height of the first rail 5.
[0029] In this embodiment, the clamp 1 can fix two different types of rails, namely, the clamp 1 can fix the first rail 5 and the second rail 6, where the height of the first rail 5 is less than the height of the second rail 6. In this embodiment, the first rail 5 is a P43 rail with a height of 140mm; the second rail 6 is a P50 rail with a height of 152mm.
[0030] In this embodiment, when the first rail 5 and the second rail 6 are joined, a person manually places the first insulating gasket 2 between the mating end faces of the first rail 5 and the second rail 6, and then the person tightens the first rail 5 and the second rail 6. One clamping plate 1 is disposed on one side of the first rail 5 and the second rail 6, a second insulating gasket 3 is fixed between the clamping plate 1 and one side of the first rail 5, and a third insulating gasket 4 is fixed between the clamping plate 1 and one side of the second rail 6; another clamping plate 1 is disposed on the other side of the first rail 5 and the second rail 6, another second insulating gasket 3 is fixed between the clamping plate 1 and the other side of the first rail 5, and another third insulating gasket 4 is fixed between the clamping plate 1 and the other side of the second rail 6. The first insulating gasket 2 insulates the mating end faces of the first rail 5 and the second rail 6 (i.e., between the mating rail ends of the first rail 5 and the second rail 6), while the second insulating gasket 3 and the third insulating gasket 4 insulate the first rail 5 and the second rail 6 from the two clamping plates 1.
[0031] In the insulated non-standard joint of this embodiment, the clamp 1 connects the first rail 5 and the second rail 6 of different types, that is, to connect the P43 rail to the P50 rail. The second insulating pad 3 and the third insulating pad 4 insulate the first rail 5 and the second rail 6 from the two clamps 1, and the first insulating pad 2 insulates the end faces of the first rail 5 and the second rail 6 that are connected.
[0032] In one possible implementation, each clamping plate 1 includes a first connecting plate 11 and a second connecting plate 12 connected together. In this embodiment, the first connecting plate 11 and the second connecting plate 12 are integrally cast. The width of the first connecting plate 11 is smaller than the width of the second connecting plate 12. The first connecting plate 11 is fixedly connected to the first rail 5, and a second insulating gasket 3 is located between the first connecting plate 11 and the first rail 5. The second connecting plate 12 is fixedly connected to the second rail 6, and a third insulating gasket 4 is located between the second connecting plate 12 and the second rail 6. The connection point of the first connecting plate 11 and the second connecting plate 12 is located to the side of the first insulating gasket 2. Specifically, the first connecting plate 11 on one clamping plate 1 is located on one side of the first rail 5, and the second connecting plate 12 on one clamping plate 1 is located on one side of the second rail 6. The first connecting plate 11 on another clamping plate 1 is located on the other side of the first rail 5, and the second connecting plate 12 on another clamping plate 1 is located on the other side of the second rail 6.
[0033] In one possible implementation, the first rail 5 includes a first rail body and two first grooves disposed on both sides of the first rail body; the second rail 6 includes a second rail body and two second grooves disposed on both sides of the second rail body. The inner height of the first groove is less than the inner height of the second groove, the inner height of the first groove is greater than the width of the first connecting plate 11, and the inner height of the second groove is greater than the width of the second connecting plate 12. The first rail 5 is a P43 rail with a height of 140mm; the second rail 6 is a P43 rail with a height of 152mm. The width of the first connecting plate 11 on the clamping plate 1 is 94.05mm, and the width of the second connecting plate 12 on the clamping plate 1 is 104.22mm. The inner height of the first groove is greater than the width of the first connecting plate 11, i.e., the inner height of the first groove is greater than 94.05mm, ensuring that the first connecting plate 11 can be locked within the first groove. The inner height of the second groove is greater than the width of the second connecting plate 12, i.e., the inner height of the second groove is greater than 104.22mm, ensuring that the second connecting plate 12 can be locked within the second groove.
[0034] The first insulating pad 2 is disposed between the end faces of the first rail body and the second rail body that are in contact with each other. Each of the first connecting plates 11 is fixedly connected in the first groove and the second insulating pad 3 is located between the first connecting plate 11 and the first groove. Specifically, the second insulating pad 3 is placed in the first groove, and then the first connecting plate 11 is snapped into the first groove. Each of the second connecting plates 12 is fixedly connected in the second groove and the third insulating pad 4 is located between the second connecting plate 12 and the second groove. Specifically, the third insulating pad 4 is placed in the second groove, and then the second connecting plate 12 is snapped into the second groove.
[0035] In one possible implementation, the first rail body is provided with a plurality of first screw holes penetrating the two first grooves. Each first connecting plate 11 has a second screw hole 111 at a position corresponding to the first screw hole. Each second insulating gasket 3 has a third screw hole at a position corresponding to the first screw hole. The insulating part also includes a plurality of first T-shaped insulating sleeves, which are respectively disposed on the plurality of second screw holes 111. The size of the first T-shaped insulating sleeve is smaller than the size of the second screw hole 111. The first T-shaped insulating sleeve extends into and is engaged with the second screw hole 111. The first screw hole, the two third screw holes, and the first T-shaped insulating sleeve, all on the same axis, are fixedly connected by a first bolt and a first nut to lock the two first connecting plates 11 within the two first grooves. The first bolt and the first nut fix the two first connecting plates 11 and the second insulating gasket 3 onto the first rail body, while the first T-shaped insulating sleeve insulates the second screw hole 111 from the first bolt, preventing electrical conduction. In this embodiment, there are six screw holes: the first screw hole on the first rail body, the second screw hole 111 on the first connecting plate 11, and the third screw hole on the second insulating gasket 3. Furthermore, the first screw hole, the second screw hole 111, and the third screw hole are designed to have the same dimensions. The second screw hole 111 and the fifth screw hole 121 can be designed as round holes or elliptical holes; designing them as elliptical holes facilitates installation.
[0036] In one possible implementation, the second rail body is provided with a plurality of fourth screw holes penetrating the two second grooves. Each second connecting plate 12 has a fifth screw hole 121 at a position corresponding to the fourth screw hole. Each third insulating gasket 4 has a sixth screw hole at a position corresponding to the fourth screw hole. The insulating part also includes a plurality of second T-shaped insulating sleeves 7, which are respectively disposed on the plurality of fifth screw holes 121. The size of the second T-shaped insulating sleeve 7 is smaller than the size of the fifth screw hole 121. The second T-shaped insulating sleeve 7 extends into and is engaged with the fifth screw hole 121. The fourth screw hole, the two sixth screw holes, and the second T-shaped insulating sleeve 7, all on the same axis, are fixedly connected by a second bolt and a second nut to lock the two second connecting plates 12 within the two second grooves. The second bolt and the second nut fix the two second connecting plates 12 and the third insulating gasket 4 onto the second rail body, while the second T-shaped insulating sleeve 7 insulates the fifth screw hole 121 and the second bolt from electrical conductivity. In this embodiment, there are six screw holes: the fourth screw hole on the second rail body, the fifth screw hole 121 on the second connecting plate 12, and the sixth screw hole on the third insulating gasket 4. Furthermore, in this embodiment, the fourth, fifth, and sixth screw holes are designed to have the same dimensions; the fifth screw hole 121 is larger than the second screw hole 111. The first and second bolts are high-strength bolts with anti-loosening properties.
[0037] In this embodiment, the first T-shaped insulating sleeve and the second T-shaped insulating sleeve 7 have the same structure, but the size of the second T-shaped insulating sleeve 7 is larger than that of the first T-shaped insulating sleeve. The upper width of both the first T-shaped insulating sleeve and the second T-shaped insulating sleeve 7 is greater than the lower width, and both the first T-shaped insulating sleeve and the second T-shaped insulating sleeve 7 have hollow channels.
[0038] The upper part of the first T-shaped insulating sleeve is located outside the second screw hole 111, and the lower part of the first T-shaped insulating sleeve extends into and is engaged in the second screw hole 111. The head of the first bolt contacts the upper part of the first T-shaped insulating sleeve, and the tail of the first bolt passes through one first T-shaped insulating sleeve, one third screw hole, and one first screw hole, and then exits from the corresponding other third screw hole and another first T-shaped insulating sleeve. After that, the first nut is locked to the tail of the first bolt. Similarly, the installation method of the second T-shaped insulating sleeve and the connection method of the second bolt and the second nut can be understood.
[0039] As one possible implementation method, see Figures 4-7 Each corner of the first and second grooves, as well as the four corners of each first connecting plate 11 and second connecting plate 12, is provided with rounded chamfers. The rounded chamfers on the first and second grooves, as well as on the first connecting plate 11 and second connecting plate 12, are to facilitate the locking of the first connecting plate 11 into the first groove and to make the two fit more closely, and the locking of the second connecting plate 12 into the second groove and to make the two fit more closely.
[0040] Further, see Figures 4-6 Each of the first connecting plates 11 and the second connecting plate 12 has a notch at one corner of its top end. This notch further facilitates the fitting of the first connecting plate 11 with the first groove and the fitting of the second connecting plate 12 with the second groove.
[0041] As one possible implementation method, see Figures 4-6 Each end face of the first connecting plate 11 that contacts the second insulating gasket 3 and each end face of the second connecting plate 12 that contacts the third insulating gasket 4 are provided with an embedded groove. The embedded grooves on each first connecting plate 11 and each second connecting plate 12 are on the same horizontal line. The embedded grooves are designed to facilitate the disassembly of the first connecting plate 11 and the second connecting plate 12 later. The first connecting plate 11 is locked in the first groove of the first rail body. Because the first connecting plate 11 has an embedded groove, there is a gap between the first connecting plate 11 and the third insulating gasket 4. This gap facilitates the removal of the first connecting plate 11 from the first rail body. Similarly, the second connecting plate 12 is also easy to remove from the second rail body.
[0042] Further, see Figure 1Each of the first connecting plates 11 has a shock-absorbing groove on the end face facing away from the second insulating pad 3, and each of the second connecting plates 12 has a shock-absorbing groove on the end face facing away from the third insulating pad 4. The shock-absorbing groove reduces the overall weight of the first connecting plates 11 and the second connecting plates 12, further facilitating installation.
[0043] In one possible implementation, the first insulating pad 2 is configured with an "I-shaped" structure, and each of the second insulating pad 3 and the third insulating pad 4 is configured with a "sheet-shaped" structure. The second insulating pad 3 and the third insulating pad 4 can be designed according to the dimensions of the first groove and the second groove.
[0044] Example 2: An insulated non-standard joint, differing from Example 1 in that the first rail 5 is a P50 rail with a height of 152mm; the second rail 6 is a P60 rail with a height of 176mm; the width of the first connecting plate 11 on the clamping plate 1 is 104.22mm, and the width of the second connecting plate 12 on the clamping plate 1 is 123.82mm. The inner height of the first groove on the first rail 5 is greater than the width of the first connecting plate 11, i.e., the inner height of the first groove is greater than 104.22mm, ensuring that the first connecting plate 11 can be locked within the first groove. The inner height of the second groove on the second rail 6 is greater than the width of the second connecting plate 12, i.e., the inner height of the second groove is greater than 123.82mm, ensuring that the second connecting plate 12 can be locked within the second groove.
[0045] In this embodiment, the insulating non-standard joint uses clamp 1 to connect different types of first rails 5 and second rails 6, that is, to connect P50 rails to P60 rails. The second insulating pad 3 and the third insulating pad 4 insulate the first rails 5 and second rails 6 from the two clamps 1, and the first insulating pad 2 insulates the end faces of the first rails 5 and second rails 6 that are connected.
[0046] Example 3: An insulated non-standard joint, differing from Example 1 in that the first rail 5 is a P60 rail with a height of 176mm; the second rail 6 is a P75 rail with a height of 192mm; the width of the first connecting plate 11 on the clamping plate 1 is 123.82mm, and the width of the second connecting plate 12 on the clamping plate 1 is 129.4mm. The inner height of the first groove on the first rail 5 is greater than the width of the first connecting plate 11, i.e., the inner height of the first groove is greater than 123.82mm, ensuring that the first connecting plate 11 can be locked within the first groove. The inner height of the second groove on the second rail 6 is greater than the width of the second connecting plate 12, i.e., the inner height of the second groove is greater than 129.4mm, ensuring that the second connecting plate 12 can be locked within the second groove.
[0047] In this embodiment, the insulating non-standard joint uses clamp 1 to connect different types of first rails 5 and second rails 6, that is, to connect P60 rails to P75 rails. The second insulating pad 3 and the third insulating pad 4 insulate the first rails 5 and second rails 6 from the two clamps 1, and the first insulating pad 2 insulates the end faces of the first rails 5 and second rails 6 that are connected.
[0048] It is worth noting that P38, P43, P50, P60, and P75 rails are all standard rails. A P38 rail refers to a rail with a weight of 38 kg per meter. The splicing of two different types of rails is not limited to the embodiments described above. The insulated joint used in this embodiment can also be used to splice P50 rails with P75 rails, etc., which will not be discussed further here.
[0049] like Figures 8-9 As shown in Embodiment 4, an insulating non-standard joint differs from Embodiment 1 in that each clamping plate 1 further includes a third connecting plate 13. The third connecting plate 13 is inverted L-shaped, with its horizontal plate positioned on one side of the first connecting plate 11 and the second connecting plate 12. The length of the third connecting plate 13 is less than the sum of the lengths of the first connecting plate 11 and the second connecting plate 12. The vertical plate of the third connecting plate 13 is fixedly connected to the working ground. The bottom of the second insulating gasket 3 is located between the vertical plate of the third connecting plate 13 and the first rail 5, and the bottom of the third insulating gasket 4 is located between the vertical plate of the third connecting plate 13 and the second rail 6. The second insulating gasket 3 and the third insulating gasket 4 insulate the third connecting plate 13 from the first rail 5 and the second rail 6, thereby satisfying the insulation requirements between the first rail 5 and the second rail 6 and the two clamping plates 1.
[0050] Because the third connecting plate 13 is fixed to the working ground, its fixed arrangement keeps the clamping plate 1 as a whole stable on the working ground, thereby preventing the clamping plate 1 from expanding or contracting with the first rail 5 and the second rail 6, and thus preventing loosening between the first connecting plate 11 and the first rail 5, and between the second connecting plate 12 and the second rail 6. The first rail 5 and the second rail 6 are fixed to the working ground by sleepers, and the third connecting plate 13 is located between the two sleepers.
[0051] Furthermore, the vertical plate of the third connecting plate 13 is provided with a fixing plate and a fixing hole. The third bolt passes through the fixing hole and locks the fixing plate to the working surface, thus achieving the overall fixed connection of the third connecting plate 13 to the working surface. The third bolt is a high-strength bolt with anti-loosening properties.
[0052] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
