Cross-road pay-off high-altitude support

Abstract

The invention discloses a trans-road paying-off high-altitude support, and is matched with a hydraulic crane for use. The trans-road paying-off high-altitude support includes a hanger, a cross rod is arranged on the hanger, a plurality of suspension rods are arranged on the cross rod, two ends of the suspensions rods are hinged with vertical rods, the two vertical rods are rotatably equipped with pulleys respectively under the suspension rods, the two pulleys are symmetrically arranged between the two vertical rods and center lines of the two pulleys are superposed, pushing devices which drive inner ends of the two pulleys to be combined or separated are arranged between the vertical rods and the suspension rods, arc-shaped circular grooves are arranged on the outer peripheries of the inner ends of the two pulleys, when the inner ends of the two pulleys are combined, the two circular grooves form an annular paying-off groove, the pulleys are connected with rotation driving devices, and the pushing devices and the rotation driving devices are connected with a control device. The trans-road paying-off high-altitude support provided by the invention is small in trans-road paying-off work amount and high in work efficiency, and can avoid phenomena of scratches and abrasions of an outer layer of an insulated wire.

Description

technical field [0001] The invention relates to a high-altitude support for laying out wires across roads used in the electric power industry. Background technique [0002] With the continuous development of the power industry, the country has new requirements for power work efficiency. In the past, when carrying out rural power network reconstruction projects and electric power construction, cross-road laying out work was often encountered. When cross-road laying out, cables were often laid on the ground, and then the cables were manually pulled up for laying out operations. , not only has a large workload and low work efficiency, but also requires government departments and traffic teams to cooperate with road closures, which will cause traffic jams on some key roads and traffic paralysis. And if the crossing distance is too long, the cable is easy to be dragged on the ground, causing scratches and wear on the outer layer of the insulated wire, causing safety hazards in t...

Problems solved by technology

In the past, when carrying out rural power network reconstruction projects and electric power construction, cross-road laying out work was often encountered. When cross-road laying out, cables were often laid on the ground, and then the cables were manually pulled up for laying out operations. , not only has a large workload and low work efficiency, but also requires government departments and traffic teams to cooperate with road closures, which will cause traffic jams on some key roads and traffic paralysis

And if the crossing distance is too long, the cable will be easily dragged on the ground, causing scratches and wear on the outer layer of the insulated wire, causing safety hazards in the line, and accidents such as power failure and tripping are very likely to occur
