Abstract

The invention discloses a transmission line release and withdrawal crossing speeder, which belongs to the field of installation, maintenance and repair equipment for overhead lines or cables, and is used to solve the need to lower the crossing 10kv line during the transmission line release and withdrawal process. ground, resulting in low work efficiency. The present invention comprises a bearing frame and two left-right symmetrical brackets; the bracket includes two bracket legs, the tops of the bracket legs are connected together, the two bracket legs form a triangular structure with the ground, and pulleys and fixed ropes are installed at the bottom ends of the bracket legs; the bearing frame includes A rotating rod and a fixed rod, the rotating rod is located between two support rods, pulleys are fixed at both ends of the rotating rod, and the fixed rod is fixedly connected with the bracket. The invention has a wide range of applications, can significantly improve the work efficiency of setting and withdrawing wires, and can protect the crossed wires at the same time.

Description

technical field [0001] The invention belongs to the field of installation, maintenance and repair equipment for overhead lines or cables, and in particular relates to a flying vehicle for releasing and withdrawing transmission lines. Background technique [0002] During the release and withdrawal of transmission lines, when the line crosses 10kV, in order to protect the 10kV line, it is necessary to cut off the power of the line and take corresponding safety measures. The main methods currently used are: ① lowering the 10kV line to the ground; ② building a reliable spanning frame. Lowering the 10kV line not only requires a lot of manpower and material resources, but also increases the labor intensity and working time of the operators. The cost of building a spanning frame is extremely high, and a large number of operators need to be invested. Although these two methods can protect 10kV lines, they have seriously affected work efficiency and caused unnecessary waste of reso...
