The current grounding method is to install the static contact of the knife gate at the grounding place of the high-voltage electric wire, and fixedly install the lifting device of the moving contact of the grounding knife gate on the ground below the static contact of the knife gate. The top of the transmission rod in the vertical direction is provided with a moving contact connected to the earth through a lead wire, and the moving contact is inserted into the static contact by lifting the transmission rod on the lifting device of the moving contact of the grounding knife brake to complete the grounding of the high-voltage wire connected to the earth. Because the static contacts and moving contacts are eroded by wind, sand, rain, snow, etc., the static contacts and moving contacts are corroded, and sand and soil impurities are attached to the static contacts and moving contacts, resulting in increased friction during the process of inserting the moving contacts into the static contacts. , The transmission rod on the lifting device of the grounding knife brake moving contact is bent and deformed.

本发明的技术解决方案是：一种接地刀闸动触头传动杆固定装置，包括底座，在底座上设置有支撑架，其特殊之处在于：所述支撑架是由多根竖杆和固设在相邻两根竖杆之间的横撑构成，在所述支撑架内设置竖直的套管，在套管与各个竖杆之间连接有长度可调的调整杆，所述调整杆的两端分别与套管和对应的竖杆铰接。The technical solution of the present invention is: a grounding knife brake moving contact transmission rod fixing device, including a base, a support frame is arranged on the base, the special feature is that the support frame is composed of a plurality of vertical rods and solid A horizontal brace arranged between two adjacent vertical bars is formed, a vertical sleeve is arranged in the support frame, and a length-adjustable adjustment rod is connected between the sleeve and each vertical rod, and the adjustment rod The two ends are respectively hinged with the casing and the corresponding vertical bar.
所述支撑架的套管为三根，且各竖杆与固设在相邻两根竖杆之间的横撑围成正三角形。There are three casings of the support frame, and each vertical bar and the cross brace fixed between two adjacent vertical bars form an equilateral triangle.
本发明的有益效果是：The beneficial effects of the present invention are:
1.通过膨胀螺栓将底座固定安装在地面上，在合闸的过程中，将套管套在接地刀闸动触头传动杆外，防止因动触头与静触头摩擦较大而造成的接地刀闸动触头传动杆弯曲变形。1. Fix the base on the ground with expansion bolts. During the closing process, put the casing outside the driving rod of the moving contact of the grounding knife brake to prevent the friction caused by the large friction between the moving contact and the static contact. The drive rod of the moving contact of the grounding knife brake is bent and deformed.
2.通过调节各个调整杆的长度，从而调节套管的位置，使套管与接地刀闸动触头传动杆配合效果更好。2. By adjusting the length of each adjustment rod, the position of the bushing is adjusted, so that the bushing and the grounding knife brake moving contact transmission rod have a better matching effect.
