Description

Technical Field

[0001] This utility model belongs to the technical field of railway engineering line reinforcement equipment, and specifically relates to a rail fastening connection device for line reinforcement. Background Technology

[0002] With rapid economic development and the expansion of road networks, the number of road-railway intersections is increasing. Furthermore, with advancements in engineering technology and rising demands for traffic efficiency, the previously widely used level crossings are no longer sufficient. In this context, jacking box culverts, which pass under existing railways, have become widely used due to their advantages such as shorter construction time, smaller land occupation, relatively lower engineering workload, and cost-effectiveness.

[0003] Before box culvert jacking construction, the existing railway line needs to be reinforced. Currently, the 3-5-3 rail clamping and processing steel longitudinal and transverse beam reinforcement system is widely used. In this reinforcement system, the connection ends of the front and rear rails are usually connected and fixed by clamping plates. However, this method has significant drawbacks. First, the clamping plates are prone to loosening and displacement under the vibration of running trains, so the condition of the clamping plates must be frequently checked and reinforced during actual construction. Second, since there is no effective connection between the front and rear rails, and the connection ends of the rails located on the inner side have no operating space, it is difficult to deal with loosening and displacement of these rail connection ends. Third, the rails inevitably experience stress deformation on the construction site, and the connection ends of loosely installed rails are prone to misalignment and tilting in such cases.

[0004] In actual construction, this type of rail misalignment is frequently observed, sometimes even resulting in the rail connection end lifting up above the rail surface elevation, posing a safety hazard to train operations on operational lines. Therefore, on construction sites, manual, periodic inspection and reinforcement of the rail connection ends are often used to maintain the rail fastening system in good working condition. Reinforcement work often involves a large number of workers and a fast pace, requiring frequent re-inspection and adjustment of the rail fasteners during subsequent construction processes. Furthermore, the lack of operating space for rail fasteners located on the inner side makes correction more difficult, resulting in a waste of manpower and resources. In rapid railway construction, frequent train traffic demands a certain speed for workers to clear tracks and avoid trains, making it easy to overlook the rail connection ends in the rush. These connection ends are precisely the weakest points in the rail fastening system, posing a safety hazard to construction on operational lines.

[0005] Therefore, to ensure the safe and rapid completion of construction tasks within the valuable time available for working on operational railway lines, it is essential to address this structural weakness and ensure the secure and reliable connection of the rail fasteners. However, there is currently a lack of cost-effective, easy-to-use, and readily employable connection tools. Utility Model Content

[0006] In order to solve the above problems, the purpose of this utility model is to provide a low-cost, simple-structured, easy-to-use, reliable, and reusable rail-fastening connection device for line reinforcement.

[0007] To achieve the above objectives, the rail fastening connection device for line reinforcement provided by this utility model includes a fishplate, bolts, and nuts; wherein, two circular holes are formed at intervals along the length direction in the middle of the connecting end of each rail; the fishplate is a curved panel that matches the structure of the middle side of the rail, and two fishplates are symmetrically installed in the middle of the two sides of the connecting end of the front and rear rails, and four circular holes corresponding to the circular holes on the two rails are formed at intervals in the middle of each fishplate; one end of each bolt passes through the two fishplates and a circular hole located in the same position on the rail in sequence and is then fixed by a nut.

[0008] The fishtail plate is made of 10mm thick steel plate by stamping.

[0009] The circular holes on the fastening rail have the same diameter as the circular holes on the fishtail plate.

[0010] Compared with existing construction techniques, the advantages of the rail fastening connection device for railway line reinforcement provided by this utility model are as follows: it can fix the rail fastening connection end with a small amount of work without adding extra mechanical equipment during railway line reinforcement, avoiding safety hazards caused by loosening of the rail fastening connection end and fixing parts, improving construction efficiency, reducing the probability of problems, accelerating construction speed, and having a simple structure, flexible operation, high safety, low cost, easy production and reusability, thus improving construction efficiency and reducing construction costs while improving safety.
