Simple line spanning frame

Abstract

The invention discloses a simple line spanning frame which comprises two stand columns and a spanning rod, wherein the spanning rod is connected with one stand column through a shaft and connected with the other stand column in a clamping manner, fixed bracing wires are arranged on the stand columns, the upper surface of the spanning rod is longitudinally provided with an elongated slot, a plurality of pulleys are arranged in the elongated slot, each pulley is provided with a draught line penetrating through the elongated slot of the spanning rod and extending out of the spanning rod, one end of the draught line is provided with a balance weight, and one end of the spanning rod, which is connected with the stand column through the shaft, is provided with a digging rope. The line is spanned by using the simple spanning frame, and requirements on various spanning environments can be met. The spanning frame has the advantages of simple structure, light weight, convenience and flexibility for operation, strong generality, safety in spanning, no hidden dangers, and convenience and simpleness for transportation and assembly. The working at height can be carried out by constructors without climbing up and down the spanning frames.

Description

technical field [0001] The invention belongs to the technical field of electric construction auxiliary equipment, and particularly relates to a simple line spanning frame. Background technique [0002] Crossover wiring is aimed at the environment of roads, rivers, mountainous areas, densely populated areas, etc. that are often encountered in line construction, such as highways, buildings and other live lines often encountered during the construction of 35KV, 10KV, 400V lines. Affected by terrain, traffic environment, population density, etc., erection is difficult, and brings inconvenience to traffic and residents' lives. It takes a long time to erect spanning spans during the construction process, and construction personnel must work at high altitudes and climb before spanning lines. Fasten the straddle line to the top of the straddle frame. After the straddle line passes the straddled line, the straddle line must be removed from the top of the straddle frame. The work inte...

Problems solved by technology

[0002] Crossing wiring is often encountered in roads, rivers, mountainous areas, densely populated areas and other environments during line construction. For example, roads, buildings and other live lines are often encountered during the construction of 35KV, 10KV, and 400V lines. The erection is affected by the terrain, traffic environment, population density, etc. It is difficult to erect, and it brings inconvenience to traffic and residents' lives. It takes a long time to erect the spanning frame during the construction process. The construction personnel must work at heights and must climb before crossing the line. Go to the top of the spanning frame to fasten the spanning line. After the spanning line passes the spanned line, it must go to the top of the spanning frame to remove the spanning line. The work intensity of the construction personnel is high, there are potential safety hazards, and the overall construction cost is high

When the crossing distance is long, there is a danger that the crossing line accidentally falls off to the live line being crossed or the arc of the crossing line is too large to reach the safe distance from the live line being crossed, resulting in a vicious accident
