The third category is special crossing. According to safety regulations, construction technical plans must be compiled for special crossings. For important crossings, the technical department should prepare the erection plan. There is no specific requirement for general crossings.
This device has the advantage of rapid construction, but it does not involve the stability design of the hydraulic lifting mechanism under the working condition of the spanning frame device, and lacks the anti-stretch design of the hydraulic lifting system in the process of building the spanning frame

Embodiment 1
[0059] combine Figure 1 to Figure 6 Describe how the present invention builds the spanning frame by means of lifting.
[0060] The hydraulic elevating span frame involved in the present invention includes two sets of hydraulic elevating systems 200, which are respectively the first hydraulic elevating system and the second hydraulic elevating system. The movement of the first hydraulic lifting system and the second hydraulic lifting system to the crossing site is controlled by the elevator operation box 210 provided on the first hydraulic lifting system and the second hydraulic lifting system respectively. And the first layer of cross bracing system is connected with the first hydraulic system and the second hydraulic system respectively. The first tier of brace system is between the first hydraulic system and the second hydraulic system.
[0061] The first-stage cross brace system is connected with the first-stage telescopic scissors on the first hydraulic system and the s...

The invention relates to a hydraulic lifting type crossing structure. The hydraulic lifting type crossing structure at least comprises a cross brace and vertical brace system and two sets of hydraulic lifting systems, wherein the cross brace and vertical brace system is arranged between the two sets of hydraulic lifting systems and is connected to a first hydraulic lifting system and a second hydraulic lifting system at two ends. According to the hydraulic lifting type crossing structure, through the hydraulic lifting systems, a worker can build the cross brace and vertical brace system downwards gradually from the top on the ground, and meanwhile, through the automatic lifting system, a way of removing upwards gradually from the bottom is realized, the building time and the removing time of the crossing structure are reduced, and the manual labor and the work high above the ground are reduced, and thus the safety risk is greatly reduced.
Description
technical field [0001] The invention relates to a line spanning frame, in particular to a hydraulic lifting type spanning frame. Background technique [0002] At this stage, when carrying out emergency repairs or building temporary cables for power supply, it is often encountered that the external cables need to cross the road, the gate of the community, or the aisle. Then the operator boards the top of the utility pole to fix and tighten the cables. This kind of mode operation time is long, and the operation is loaded down with trivial details, and the utility pole erected temporarily is not very firm sometimes, brings certain potential safety hazard to the climbing of operating personnel. [0003] With the large-scale development of my country's power grid construction and the overall development of the economy and society, the number of special crossings such as high-speed railways and expressways in the construction of power lines has increased rapidly, and the crossing...
