Cable spanning device for electric power construction

Abstract

The invention discloses a cable spanning device for electric power construction, comprising a transport vehicle, a support frame and a mounting platform are installed on the transport vehicle, a lifting mechanism is installed on the mounting platform, and a supporting mechanism is installed on the top of the lifting mechanism , A first connecting rod and a second connecting rod are installed on the lifting mechanism, one end of the first connecting rod and the second connecting rod is installed on the lifting mechanism, and the other end is installed on the supporting mechanism. The invention only needs to be moved to the working position under the action of the transport vehicle, without assembly and disassembly, which greatly improves the work efficiency, and the lifting mechanism can open the support mechanism to achieve the purpose of crossing obstacles and the erection of cables , and the lifting mechanism can retract the supporting mechanism, which ensures the safety of the device during transportation. The setting of the two supporting mechanisms ensures the stability of the device and prevents the Tilting or even damage greatly guarantees the service life of the device.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, in particular to a cable crossing device for electric power 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
