Background
With the high-speed development of power networks, road networks, railway networks and communication networks, the networks are staggered more and more, so that the frequency in the power network stringing construction needs to cross over objects such as roads, railways and power lines. In order to protect the spanning objects, the spanning objects are usually protected by means of erecting moso bamboo or steel pipe spanning frames or metal lattice type spanning frames and laying protective nets. The bearing cable of the existing crossing construction protective net is generally a Dyneema rope, and a common hoisting tackle is suspended and then falls to the ground and is tightened on a ground anchor; the trawl rope is generally a nylon rope, is tied on the supporting tube one by one, is suspended by the hoisting tackle and then falls to the ground to be tightened, the carrying rope adopts a Dyneema rope, on one hand, the cost of the Dyneema rope is higher, on the other hand, the Dyneema rope is exposed to the sun and drenched in the open air for a long time, the aging speed is very fast, and the service life is short; the supporting tube is usually assembled by moso bamboo or epoxy resin tubes, and if the supporting tube is assembled by moso bamboo, the supporting tube is heavy due to the large density of the moso bamboo, and the moso bamboo is generally bound and spliced by steel wires and is likely to fall off under the influence of severe weather such as strong wind, heavy rain and the like, so that potential safety hazards exist; if the supporting tube is formed by assembling epoxy resin tubes, the bending strength of the epoxy resin tubes is not high, and if the supporting tube is used for crossing construction, a tube with a large tube diameter needs to be purchased, so that the economy is poor; the nylon net is a standard net directly purchased from the market; the nylon net is connected with shackles or nylon pulleys and the like which are arranged on a bearing cable to realize net hanging; the supporting pipe is firstly bound on a steel ring or connected on a hoisting tackle on site, and then the steel ring or the hoisting tackle is hung on the bearing rope in a penetrating manner to realize pipe hanging. If the nylon wire hangs with the shackle, the shackle can overturn under the action of gravity, causes the round pin axle to hang on the carrier cable for at the in-process of drag and drop protection network, the round pin axle of shackle probably takes off under the carrier cable frictional force effect, has the potential safety hazard that the eminence of shackle falls. If the suspension of stay tube needs the operation personnel to manually operate at the high altitude with the steel ring at on-the-spot ligature, takes a lot of work and wastes time, and the ligature quality can't guarantee again, and the steel ring can wear and tear the bearing rope at drag and drop protection network in-process, influences bearing rope life.
