High-altitude crossing cable construction frame

Abstract

The invention discloses an overhead cable scaffold, which comprises two floor stands that are arranged in parallel, wherein a telescopic cross bar is connected between the two top surfaces of the floor stands; and cable supporting platforms are fixedly connected to the top surfaces of the floor stands. Rollers on the cable supporting platforms save effort for dragging the cable and can not damage the cable in the dragging process; and upper limiting idler wheels can avoid the trouble for the construction as the cable drops from the floor stands due to incorrect dragging. The overhead cable scaffold further can adjust the length of the cross bar according to the spanning length, compared with a multi-rod splicing manner, save a lot of time, and improve the construction efficiency. The floor stands and the cross bar are covered with insulated rubber, so that the safety factor is high, and the accident rate is low.

Description

technical field [0001] The invention relates to the field of power transmission line engineering, in particular to a high-altitude spanning cable construction frame. Background technique [0002] With the rapid development of national infrastructure construction, the development of electric power engineering is extremely rapid. High-voltage lines are spread all over the country. Buildings and vulnerable green crop greenhouses need to set up crossing frames or take other crossing transition measures to ensure the passage of lines. At present, the crossing frame is generally used to solve the transition problem of overhead lines. The existing overhead line spanning frame is relatively simple. Scaffolding is erected on both sides of the obstacle, and the wire follows the traction rope and passes over the obstacle. Large, once the construction is improper or encounters harsh natural conditions, the wires are easy to fall off from the scaffolding, which can easily cause major tr...

Problems solved by technology

At present, the crossing frame is generally used to solve the transition problem of overhead lines. The existing overhead line spanning frame is relatively simple. Scaffolding is erected on both sides of the obstacle, and the wire follows the traction rope and passes over the obstacle. Large, once the construction is improper or encounters harsh natural conditions, the wires are easy to fall off from the scaffolding, which can easily cause major traffic accidents. If they fall on the existing lines and cause damage to the existing lines, it will inevitably cause major economic losses.
