AI Technical Summary
Due to long-term exposure to outdoor environments, the railway contact network is prone to breaking due to aging, causing losses to the contact network to fall. Due to its remote location, it is impossible to understand the fracture location as soon as possible, which will affect the normal operation of the high-speed rail.
A detection structure of a railway contact network compensation device is designed, including pillars, mounting brackets, slow-down mechanisms, rollers, compensation ropes, sinkers, transmitters, slide chutes, sliding plates and springs. The rotation shaft drives the gear set to rotate, so that the slow drop of the sinker can be achieved; the sliding plate cooperates with the spring to buffer, and send messages through the sender to understand the breaking position as soon as possible.
It effectively avoids damage caused by rapid fall of the pendulum, reduces maintenance costs, and allows staff to understand the breaking position as soon as possible to ensure the normal operation of the high-speed rail.

[0002] The railway overhead contact network is a transmission line erected above the railway line to supply power to electric locomotives. The electric current that high-speed trains rely on is transmitted through the overhead contact network on the top of the locomotive. The overhead contact network is in an outdoor environment, and the load-bearing cables and contact network lines are affected by the outdoor temperature, which will produce thermal expansion and contraction, thereby causing the contact network lines to lengthen or shorten.
[0003] In order to adapt to this change, it is necessary to use a contact network compensation device. However, the contact network is in an outdoor environment for a long time, and it is inevitable that the contact network will break due to aging, thereby falling and causing losses. At the same time, due to the remote location of the contact network, it is impossible to know the broken location in the first time, which leads to the high-speed rail being unable to operate normally.

[0023] When in use, the traction rope 5 is driven to descend through the weight 4, and when the traction rope 5 descends, the rotating shaft 6 is driven to rotate, and a toothed disc 9 is fixedly installed inside the rotating shaft 6, and the toothed disc 9 is meshed with gear 2 8, and gear 2 8 is meshed with gear 1 7.
