Description

Technical Field

[0001] The utility model relates to the technical field related to power grid construction, in particular to a high-speed railway crossing device. Background Art

[0002] The purpose of power grid construction is to meet the growing power demand in my country and ensure the stable development of the national economy and society. During the construction, high-speed railways and other locations will be encountered. Therefore, when laying cables, it is necessary to use crossing devices;

[0003] A high-speed railway crossing device for power grid construction disclosed in the existing announcement number CN216016399U includes a cable bracket, a through circular hole is opened at the upper end of the cable bracket, and two cable brackets are symmetrical to each other; a connecting rod, and the upper ends of the two cable brackets are fixedly connected with an arc-shaped connecting rod; the connecting rod includes: a fixing ring A is fixedly sleeved in the middle of the upper end of the connecting rod; a connecting block A is fixedly installed at the lower end of the outer annular side wall of the fixing ring A, and a through circular hole is opened in the middle of the connecting block A; a through fixing pipe A is inserted in the circular hole of the connecting block A;

[0004] The above document can solve the problem of existing crossing devices. Since the cable line is relatively long because it crosses the railway, it needs to lift the middle part of the cable line upwards. If the cable line is too long, the middle part will be lower than the two ends, resulting in the top being too high when the vehicle passes by and the cable line will be hung. However, there are two-lane and three-lane roads on the high-speed railway. The crossing device in the above document is difficult to adapt to railways of different widths and sizes, and its use is relatively limited. In addition, the power grid cable will contact the ground during the wire pulling process, which will cause dirt to adhere to the surface of the cable. The above crossing device is not convenient for cleaning the cable. Therefore, we propose a high-speed railway crossing device to solve the above problems. Utility Model Content
