Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation, and more particularly to an assembled contact rail shock-absorbing and insulating support. Background Art

[0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to travel on specific tracks. It is a general term for "rapid, high-capacity public transportation that is usually powered by electricity and adopts a wheel-rail operation mode." In subway and urban rail transit systems, the contact rail is a device that transmits electrical energy to electric traction vehicles. The contact rail transmits electrical energy to the vehicle through the collector shoe. Depending on the different ways in which the collector shoe draws current from the contact rail, the contact rail can be installed in three ways: top contact, bottom contact, and side contact. The top contact method is easy to install, while the side contact method is less commonly used due to its high installation precision requirements. The bottom current-transferring contact rail protective cover has good protection performance for the live contact rail, making it difficult for the live contact rail to be touched unintentionally, which can ensure personal safety. In addition, the bottom current-transferring method is better than the top current-transferring method in terms of shielding against rain and snow, which can ensure the safe and reliable operation of the traction network system.

[0003] At present, all projects in China's urban rail transit that use contact rails need to use insulating supports. The function of insulating supports is to support and fix the contact rails and provide insulation protection. The existing insulating supports include three types: insulators, insulating supports and insulating brackets, which are as follows: Figure 1 As shown in a, b, and c.

[0004] There are two main problems with existing contact rail insulation brackets:

[0005] The first problem is a lack of vibration damping. Contact rail insulation supports are typically installed on the roadbed. When trains pass at high speed, the roadbed vibrates frequently and violently, causing significant vibrations in the base of the insulation supports. With the increasing adoption of vibration-damping roadbeds, the inherent elasticity of the roadbed exacerbates these vibrations. Over time, frequent vibrations can lead to loosening of the fastening bolts on the insulation supports, slippage of the contact rail and protective cover, and other problems. This reduces assembly stability and seriously impacts driving safety.

[0006] The second problem is that it is difficult to adjust the installation height. The contact rail insulation support is installed on the track bed or rail sleeper. Since there are many types of track beds and the installation height of each type of track bed is different, the structural dimensions of the contact rail insulation support are diverse. On the one hand, manufacturers need to produce a variety of molds, which leads to high costs. On the other hand, it is inconvenient to install on the construction site, and there are also many types of spare parts required for later operation and maintenance. Among the existing insulation support products, whether it is insulators, insulation brackets or insulation supports, the overall structural height cannot be adjusted, and only slight adjustments can be achieved through the local structure on the insulation support. Specifically:

[0007] The insulator height is fixed and has no adjustment function;

[0008] The insulation bracket is fine-tuned through the long hole on the bracket, and the adjustment range is small, about 30mm;

[0009] Currently, adjustable insulating supports utilize a structure that achieves overall height adjustment by vertically dislocating the left and right insulating support structures. The left insulating support structure features a vertically oriented slot that serves as a bolt hole. By changing the bolt's secure position within the slot, the height between the two vertical connecting members can be adjusted, allowing for vertical adjustment of the left and right sections at different connection positions. However, this solution suffers from the problem of the connecting bolt bearing the entire vertical load, resulting in poor structural reliability. Furthermore, due to the limitations of the connector structure, the slot's length is limited, resulting in a narrow adjustment range.

[0010] Therefore, it is necessary to propose an assembled contact rail shock-absorbing insulating support to solve the problems existing in the prior art. Summary of the Invention
