Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, and in particular to an insulating connection structure for railway tracks. Background Technology

[0002] Railway track insulation connection structures are devices installed at specific locations on railway tracks. They are mainly composed of insulating materials and related connecting components. Their function is crucial. On the one hand, they enable electrical isolation between track circuits, preventing current leakage and interference, ensuring the accuracy and stability of track circuit signal transmission, and assisting in the normal operation of train operation control and signal systems. On the other hand, they effectively prevent stray currents from corroding the track and surrounding facilities, extending the service life of the track and related equipment, ensuring the safety and reliability of railway lines, reducing maintenance costs, and ensuring efficient operation of railway transportation.

[0003] A search revealed that the document with publication number "CN222666424U" mentions "a railway track insulation connection device, comprising two clamping plates, two railway tracks disposed between the two clamping plates, multiple bolts disposed inside the railway tracks, the two ends of the bolts passing through the two clamping plates respectively, insulating plates disposed on opposite sides of the two clamping plates, insulating sleeves disposed on the outer sides of the bolts, nuts screwed to the front ends of the bolts, and multiple anti-loosening mechanisms fixed on the front surface of the clamping plates." In use, this railway track insulation connection device, by setting anti-loosening mechanisms, clamps the two railway tracks with the insulating plates and clamping plates. Then, the insulating sleeve is inserted into the insulating plates, clamping plates, and railway tracks. Next, the bolt is inserted into the insulating sleeve, and then the nut is screwed onto the bolt. After the nut is tightened, the hexagonal head of the bolt is inserted into the hexagonal hole. Then, the hexagonal cylinder is rotated to adjust its angle to fit the nut, allowing the hexagonal cylinder and nut to engage. The locking block engages with the locking hole, thus preventing the nut from rotating and loosening.

[0004] However, at the junctions of different sections of railway tracks, it is necessary to differentiate the electrical connections between the different sections by insulation. However, most common track connections use mechanical connections, which do not give much consideration to electrical insulation. Furthermore, the insulation of the electrical insulation parts is poor, and at the intersection points, electrical interference can easily occur, which may lead to dangerous situations in severe cases.

[0005] Therefore, we provide a railway track insulation connection structure to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An insulating connection structure for railway tracks includes a track body, a track insulating connection assembly disposed in the middle of the track body, and an insulating pad mounted on the inner side of the track body.

[0019] 1. This utility model utilizes a track insulation connection assembly. When needed, two insulating pads are placed at the joint of the track body, and the C-shaped side wings clamp the track body's web, thus limiting the position of the insulating pads and preparing for subsequent fixing. The connecting rail pad, as a rigid support at the joint of the two track bodies, is made of rigid epoxy resin composite material, which effectively improves the stability and durability of the track connection, ensuring train operation safety. Furthermore, the fixing rivets penetrate the track connecting plate and the C-shaped side wings, ensuring a firm connection and electrical insulation, preventing short circuits caused by metal contact, and further enhancing the overall safety and reliability of the track connection.

[0027] Please see Figure 1-4 As shown, this utility model provides a technical solution: a railway track insulation connection structure, including a track body 1, a track insulation connection assembly 2 disposed in the middle of the track body 1, the track insulation connection assembly 2 including an insulating pad 201 installed on the inner side of the track body 1, C-shaped side wings 202 disposed on the front and rear sides of the insulating pad 201, a connecting rail pad 203 disposed on the inner side of the insulating pad 201, an insulating sealing sleeve 204 disposed on the inner ends of the left and right sides of the connecting rail pad 203, an elastic insulating sheet 205 disposed on the inner side of the insulating sealing sleeve 204, a track connecting plate 206 disposed on the front and rear sides of the C-shaped side wings 202, and a fixing rivet 207 disposed on the inner side of the track connecting plate 206.

[0028] Furthermore, the elastic insulating sheet 205 and the insulating sealing sleeve 204 are connected by a slot. The elastic insulating sheet 205 is made of polytetrafluoroethylene. When needed, the elastic insulating sheet 205 connecting the left and right ends of the rail pad 203 further enhances the insulation effect and buffering performance of the rail connection through its excellent insulation performance and elastic recovery force, effectively reducing the vibration and noise during train operation and improving the safety and comfort of the overall track system.

[0029] Furthermore, the insulating pad 201 is connected to the track body 1 by a slot through the C-shaped side wings 202. The insulating pad 201 and the track body 1 are of equal size, and the C-shaped side wings 202 are arranged symmetrically on the left and right. When needed, the two insulating pads 201 are respectively placed on the joint of the track body 1, and the C-shaped side wings 202 are used to hold the waist of the track body 1, thereby limiting the insulating pad 201 and preparing for subsequent fixing.

[0030] Furthermore, the cross-section of the connecting rail pad 203 is the same as that of the track body 1. The connecting rail pad 203 is made of rigid epoxy resin composite material. When needed, the connecting rail pad 203 serves as a rigid support at the joint of the two track bodies 1.

[0031] Furthermore, the track connecting plate 206 and the C-shaped side wing 202 are connected by a fixing rivet 207. The track connecting plate 206 is made of high-strength steel, and the surface of the fixing rivet 207 is coated with an insulating layer. When needed, the fixing rivet 207 passes through the track connecting plate 206 and the C-shaped side wing 202 to ensure a firm connection and electrical insulation, preventing short circuits caused by metal contact, and further improving the overall safety and reliability of the track connection.

[0032] Furthermore, the insulating sealing sleeve 204 and the connecting rail pad 203 are connected by a slot, and the insulating sealing sleeve 204 and the connecting rail pad 203 are symmetrically arranged on the left and right. The insulating sealing sleeve 204 is made of neoprene rubber. When needed, the insulating sealing sleeve 204 can effectively isolate external moisture and impurities, ensure the electrical insulation performance of the rail connection, prevent current leakage, and ensure the safety and stability of train operation.

[0033] Working principle: When needed, first attach the insulating pad 201 to the connecting surface of the two rail bodies 1, and then use the C-shaped side wings 202 to clip the insulating pad 201 to the rail web of the rail body 1.

After the connection is completed, attach the rail connecting plate 206 to the outside of the C-shaped side wings 202 on both sides, and use the fixing rivets 207 to make a through connection. This completes the use process of a railway track insulation connection structure.
