Highway crossing support frame for power grid construction

Abstract

The invention discloses a highway crossing support frame for power grid construction. One side of the upper part of a frame is provided with a flat plate. A bottom plate is arranged on the upper partof the flat plate. One side of the bottom plate is provided with a coaming plate. First support rods are movably installed at the two ends of the coaming plate through hinges. One end of a second hydraulic cylinder is movably connected with a connecting rod, and the other end of the second hydraulic cylinder is movably connected with the first support rods through a hinge head. A second support rod is movably connected with a first connecting plate. One end of a third hydraulic cylinder is movably connected with the first support rods through the hinge head, and the other end of the third hydraulic cylinder is movably connected with the second support rod through the hinge head. The first support frame and the second support frame are arranged on the vehicle body. The second hydraulic cylinder is utilized to support the first support frame and the third hydraulic cylinder is utilized to support the second support frame in use so that the erection of the support frame is quickly and efficiently completed, the efficiency of cable construction is improved, the stability of the support frame is enhanced and the personal safety of construction personnel and highway colleagues is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, in particular to a road spanning support frame for power grid construction. Background technique [0002] The transmission line crossing support frame is a common equipment in the field of electric power construction. When erecting a new power grid or temporary construction of the power grid, there are often situations where transmission lines cross roads or existing communication lines. Erection of transmission lines across the support frame. [0003] The existing transmission line crossing support frame generally uses scaffolding to erect the support frame on both sides of the road, and the cables are erected on the upper part of the support frame, which has the following defects: 1) The scaffolding needs to be erected manually, and the efficiency of its erection is low, resulting in The construction period of the cable erection is longer; 2) the stability of the scaffold it...

[0003] The existing transmission line crossing support frame generally uses scaffolding to erect the support frame on both sides of the road, and the cables are erected on the upper part of the support frame, which has the following defects: 1) The scaffolding needs to be erected manually, and the efficiency of its erection is low, resulting in The construction period of the cable erection is longer; 2) the stability of the scaffold itself is poor, especially when the height of the scaffold is high, the upper part of the scaffold will shake or even collapse, threatening the personal safety of construction workers and road passers-by; and When the cable is erected, the cable needs to be pulled, and the cable generates friction on the upper end of the scaffold, which intensifies the shaking of the scaffold and lowers the safety; 3) The cable between the two ends of the scaffold is bent under its own gravity, making the cable The support height of the cable is reduced, which affects the safety of road vehicles
