Description

Technical Field

[0001] The utility model belongs to the technical field of electrified railways, and more specifically, relates to an electrified railway contact network deicing device based on a contact network cross-line robot. Background Art

[0002] As an efficient, safe, environmentally friendly, comfortable and fast public transportation mode, electrified railways have been adopted by many countries, but some railway lines are located in areas with higher latitudes and lower average annual temperatures. As a key component in the traction power supply system, the overhead contact network is erected along the railway line. The dynamically running train obtains traction power through the sliding electrical contact between the carbon slide (bow) supported by the pantograph on the roof and the overhead contact network (net). The sliding electrical contact quality between the pantograph and the catenary directly determines the stability and efficiency of traction power transmission.

[0003] In recent years, railways around the world have often been affected by extreme weather. Although there have been experimental attempts to melt the contact network by injecting Joule heat generated by direct current and alternating current into the contact network, the structure of the contact network is more complex than that of traditional transmission lines. It includes key components such as load-bearing cables, suspensions, wire clamps, and contact wires. The types, materials, and structural dimensions of the wires of each component are completely different, resulting in extremely uneven distribution of current in the various components of the contact network after the current is injected, that is, the Joule heat generated by the non-uniformly distributed current is unevenly distributed throughout the contact network. The temperature distribution of each component in the contact network is unpredictable, and it is difficult to prevent the risk of wire melting caused by excessive local temperature. Considering the risk of contact network melting, there are currently few engineering cases of using electric heating to melt ice to de-ice the contact network. Nowadays, more people use manual knocking to de-ice, but this method poses certain risks to the personal safety of construction workers, and the de-icing efficiency is not high. Therefore, it is urgent to propose a more efficient and safe contact network de-icing device / technology / method. Utility Model Content

[0035] The utility model electrified railway contact network deicing device comprises two support cable motion mechanical arms 1, two contact line motion mechanical arms 3 and a connecting mechanical arm 5, which connect the support cable deicing module 2, the contact line deicing module 4 and the hanging string deicing module 6 as a whole, forming a contact network cross-line robot. In practical applications, the two support cable motion mechanical arms 1 and the two contact line motion mechanical arms 3 are respectively installed on the contact line and the support cable, and the entire motion mechanical arm is driven to perform a climbing motion along the contact line or the support cable by the rotation of the motor built into the above motion mechanical arms, thereby driving the entire deicing device to move on the electrified railway contact network.

[0036] In the electrified railway contact network, there is a contact network wrist-arm support device, which may hinder the movement route of the de-icing device. The utility model effectively solves this problem by providing two support cable motion mechanical arms 1, two contact line motion mechanical arms 3 and a connecting mechanical arm 5 to form a drive mechanism connecting the mechanical arms.

When the support cable deicing module 2 and the contact line deicing module 4 cross the support device, they return to their original state. Finally, the front support cable movement mechanical arm 1 and the contact line movement mechanical arm 3 provide power. The rear support cable movement mechanical arm 1 and the contact line movement mechanical arm 3 lift off the support cable and the contact line through their own rotation, cross the support device and fall back to the support cable and the contact line, thereby completing the process of the entire deicing device crossing the contact network wrist-arm support device. It can be seen that when the entire deicing device crosses the base network, the connecting mechanical arm 5 connecting the support cable deicing module 2 and the contact line deicing module 4 can keep the entire deicing device balanced on the electrified railway contact network through its rotation.
