Description

Technical Field

[0001] This utility model relates to the field of rail welding technology, and more specifically, to a special pad for moving and climbing rails for ballastless tracks. Background Technology

[0002] Currently, during on-site mobile welding operations, the welding machine's dimensions conflict with the structure of the SFC type fastener system for ballastless tracks, preventing the machine from being directly positioned for welding. It is necessary to raise the rails on both sides of the weld joint to prevent interference between the welding machine and the iron base plate structure of the SFC type fastener system when clamped. Raising the rails on both sides of the weld joint creates a slope, known as slope support. Once the welding machine climbs the slope, the welding operation can be completed smoothly.

[0003] Existing technologies for slope support of SFC-type fastener rails involve on-site personnel using wooden planks, round steel bars, or steel plates of a certain height to support the rail base. This method is somewhat arbitrary, with inconsistent sizes and specifications of support tools, unreliable structural strength, difficulty in achieving lateral and longitudinal positioning and fixation, posing safety hazards, and increasing the risk of welding machines derailing or overturning. Existing technologies use sleeper bolts as a fixing reference to achieve lateral and longitudinal locking of the support blocks on the rail bearing groove. This technology is only suitable for track work on ballasted tracks with anchor bolts, and its size and specifications are set based on the anchor bolts on the concrete sleeper bearing groove. It is not suitable for slope support work on SFC-type fastener rails on ballastless tracks. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a special pad for climbing slopes for moving rails in ballastless tracks, which is suitable for welding operations using SFC type fasteners for ballastless tracks. It can achieve double locking between the pad and the iron base plate of the SFC type fastener for ballastless tracks, and between the rail and the pad, thereby fixing the rail in both the lateral and longitudinal directions, reducing safety hazards, and avoiding the risk of the welding machine derailing or overturning.

[0005] Based on the above objectives, this utility model provides a special pad block for moving and welding rails for ballastless tracks, comprising a rail base corner pressure block, a pad block body, and a positioning plug, wherein: the top of the pad block body is provided with an installation plate, the top surface of the installation plate is provided with a groove and a first installation hole, the bottom of the pad block body is provided with a first locking member and a second locking member arranged opposite to each other, the first locking member is used to engage in a groove on one side of the iron pad base, and the second locking member is used to engage in a groove on the other side of the iron pad base, the lower end of the positioning plug passes through the groove and is used to engage in a locking groove in the middle of the iron pad base; the top of the rail base corner pressure block is provided with an abutment plate, the bottom surface of the abutment plate is used to fit against the inclined surface on one side of the rail base corner, and the bottom of the rail base corner pressure block is installed in the first installation hole.

[0006] Optionally, it also includes bolts, and the top surface of the abutment plate has a second mounting hole. The bolts pass through the second mounting hole and the first mounting hole in sequence to install the rail bottom corner pressure block on the pad block body.

[0007] Optionally, it also includes an anti-drop pin, wherein the side of the positioning plug has a pin hole, the anti-drop pin is installed in the pin hole, and the top of the positioning plug has an upper plate, the outer dimensions of which are larger than the dimensions of the slot.

[0008] Optionally, a height pad is also included, which is used to place on the bottom surface of the rail base, and the top surface of the height pad has weight-reducing holes.

[0009] Optionally, the pad body is integrally formed.

[0010] This utility model provides a special rail movable welding climbing pad for ballastless track, including a rail bottom corner pressure block, a pad body, and a positioning plug. First, the bottom of the rail bottom corner pressure block is installed in the first mounting hole; then, the lower end of the positioning plug passes through the groove on the pad body; finally, the first clip is engaged in the groove on one side of the iron pad base, the second clip is engaged in the groove on the other side of the iron pad base, the lower end of the positioning plug is engaged in the engagement groove in the middle of the iron pad base, and the bottom surface of the abutment plate at the top of the rail bottom corner pressure block is attached to the inclined surface on one side of the rail bottom corner. This utility model provides a special rail moving welding and climbing pad for ballastless tracks, applicable to welding operations using SFC type fasteners for ballastless tracks. By engaging the first clip into a groove on one side of the iron base plate and the second clip into a groove on the other side of the iron base plate, the pad is fixed longitudinally along the length of the rail and vertically to the ground on the iron base plate. The positioning plug achieves lateral fixation of the pad on the iron base plate perpendicular to the length of the rail. By attaching the bottom surface of the abutment plate at the top of the rail base corner pressure block to the inclined surface on one side of the rail base corner, the rail is fixed laterally and longitudinally. This achieves double locking between the pad and the iron base plate of the SFC type fastener for ballastless tracks, and between the rail and the pad, thus fixing the rail laterally and longitudinally, reducing safety hazards and avoiding the risk of the welding machine derailing or overturning.

The bottom of the pad body 2 is provided with a first locking member 7 and a second locking member 8 arranged opposite to each other. The first locking member 7 is used to engage with a groove 9 on one side of the iron base plate, and the second locking member 8 is used to engage with a groove 10 on the other side of the iron base plate. The lower end of the positioning plug 3 passes through the slot 5 and is used to engage with a locking groove 11 in the middle of the iron base plate. The top of the rail base corner pressure block 1 is provided with an abutment plate 12, the bottom surface of which is used to fit against the inclined surface of one side of the rail base corner. The bottom of the rail base corner pressure block 1 is installed in the first mounting hole 6.

[0021] The present invention provides a special pad for moving and welding rails for climbing slopes in ballastless tracks, comprising a rail base corner pressure block 1, a pad body 2, and a positioning plug 3. First, the bottom of the rail base corner pressure block 1 is installed in the first mounting hole 6; then, the lower end of the positioning plug 3 passes through the groove 5 on the pad body 2; finally, the first clip 7 is snapped into the groove 9 on one side of the iron pad base, the second clip 8 is snapped into the groove 10 on the other side of the iron pad base, the lower end of the positioning plug 3 is snapped into the middle snap-fit ​​groove 11 of the iron pad base, and the bottom surface of the abutment plate 12 at the top of the rail base corner pressure block 1 is attached to the inclined surface on one side of the rail base corner. This utility model provides a special rail moving welding and climbing pad for ballastless tracks, which is suitable for welding operations using SFC type fasteners for ballastless tracks. By engaging the first clamp 7 into the groove 9 on one side of the iron pad base and the second clamp 8 into the groove 10 on the other side of the iron pad base, the pad is fixed longitudinally along the length of the rail and vertically to the ground on the iron pad base. The positioning plug 3 is used to fix the pad laterally on the iron pad base perpendicular to the length of the rail. By attaching the bottom surface of the abutment plate 12 at the top of the rail bottom corner pressure block 1 to the inclined surface on one side of the rail bottom corner, the rail is fixed laterally and longitudinally. This achieves double locking between the pad and the iron pad base of the SFC type fastener for ballastless tracks, and between the rail and the pad, thus fixing the rail laterally and longitudinally, reducing safety hazards and avoiding the risk of the welding machine derailing or overturning.

[0022] It should be noted that: the iron pad and iron seat refer to the iron pad and iron seat of the SFC type fastener; the groove 9 on one side of the iron pad and iron seat, the groove 10 on the other side of the iron pad and iron seat, and the locking groove 11 in the middle of the iron pad and iron seat are all existing structures in the existing iron pad and iron seat of the SFC type fastener, such as... Figure 5 As shown; the bottom surface of the abutment plate 12 is an inclined surface that matches the inclined surface of the rail bottom corner, which can better fit with the inclined surface of the rail bottom corner side of the rail.

[0023] like Figure 1 and Figure 2 As shown, it also includes bolts 13. A second mounting hole 14 is provided on the top surface of the abutment plate 12. After the bolts 13 pass through the second mounting hole 14 and the first mounting hole 6 in sequence, the rail base corner pressure block 1 is installed on the pad body 2. In this embodiment, the bolts 13 can pass through the second mounting hole 14 in the rail base corner pressure block 1 and the first mounting hole 6 in the pad body 2. Power tools and sockets can be used to quickly tighten and loosen the rail base corner fixing pressure block. The bolts 13 can fix the rail base corner pressure block 1 to the rail base corner, which improves the convenience of disassembly and installation of the special pad for rail moving welding and climbing slope of ballastless track.

[0024] like Figure 1 and Figure 2As shown, it also includes an anti-drop pin 15. A pin hole is provided on the side of the positioning plug 3, and the anti-drop pin 15 is installed in the pin hole. An upper plate 16 is provided on the top of the positioning plug 3, and the outer dimensions of the upper plate 16 are larger than the dimensions of the slot 5. In this embodiment, the anti-drop pin 15 and the upper plate 16 can limit the positioning plug 3, preventing it from falling out of the slot 5 and onto the railway site, thus reducing safety hazards.

[0025] like Figure 3 and Figure 4 As shown, it also includes a height pad 17, which is used to support the bottom surface of the rail base. The top surface of the height pad 17 has a weight-reducing hole 18. In this embodiment, the height pad 17 can be made of Q235 steel, which has high strength and wear resistance. Before attaching the rail base corner clamping block 1 to the inclined surface of the rail base corner, the height pad 17 is placed on the bottom of the rail. After raising the rail, it is convenient to attach the rail base corner clamping block 1 to the inclined surface of the rail base corner. The weight-reducing hole 18 reduces the weight of the height pad 17 and also makes it easier for manual one-handed operation.
