Abstract
The utility model discloses a kind of protection network is crossed over for electric transmission line erection construction, including some insulation carrier cables and the safety net being connected between two adjacent insulation carrier cables, at least gap is equipped with two layers of baffle safety band above the safety net, the end of each baffle safety band is affixed with corresponding insulation carrier cable, and each baffle safety band is formed by two sections of band bodies by hasp adhesion.The utility model is by the way that at least two layers of baffle safety band is adhered in gap above existing safety net, and baffle safety band is to be formed by two sections of band bodies by hasp adhesion, form catenary suspension type continuous vulcanization profile, using successively absorbing, buffer the principle of fracture material impact kinetic energy, the impact kinetic energy of buffering fracture material is absorbed by the adhesion strength of hasp adhesion, fracture material is reduced to fall speed, can be in the case where not changing construction method, making original safety net, to be changed into fracture material buffered directly facing fracture material impact, born again by safety net after energy-absorbing, so as to greatly increase the resistance to scope being hit of safety net.
Description
Technical field
It the utility model is related to a kind of charging construction device, more particularly to a kind of leap for electric transmission line erection construction
Protection network.
Background technology
In the construction of power network project of transmitting and converting electricity, newly-built transmission line of electricity often ultra-high-tension power transmission line, the railway with having run
And the object being spanned such as highway geographically produces intersection, newly-built circuit ground wire needs to cross object being spanned.In order to ensure this is led
Safe distance between ground wire and object being spanned, it is necessary to set up across protector therebetween in advance.
It is existing across protector be usually take the mode across protection network set up below circuit it is important by across
More thing（The critical facilitys such as highway, railway, power circuit）Protected.The insulation for mainly including being adjacently positioned across protection network is held
Power rope and the safety net being connected between two adjacent insulation carrier cables, overhead is protected just with the safety net of single nylon material
Fracture material safety net, when in face of the impact of large-section lead and messenger, the impact resistance ability of safety net faces increasing
Test, it is most likely that safety net fracture occurs and destroys the situation for being spanned thing.
Utility model content
The purpose of this utility model, which is to provide one kind and can reduce fracture material, falls speed, and it is dynamic to absorb buffering fracture material impact
Can, reduce existing safety net directly bear fracture material impact dynamics be used for electric transmission line erection construction cross over protection network.
This protection network of crossing over for electric transmission line erection construction provided by the utility model, including some insulation loads
Rope and the safety net being connected between two adjacent insulation carrier cables, at least upper and lower gap is equipped with two layers and delayed above the safety net
Safety belt is rushed, the end of each baffle safety band is affixed with corresponding insulation carrier cable, and each baffle safety band is by two sections of band bodies
Formed by hasp adhesion.
The baffle safety band is made up of fabric.
The baffle safety band is made up of aramid fiber.
To realize that step configures, buffering dynamics are increased, the baffle safety carries upper and lower two layers, two baffle safety
Ultimate range between band is more than the ultimate range between baffle safety band and safety net.
Two sections of the upper strata baffle safety band dock adhesion by the hasp positioned at upper surface with body and formed, the lower floor
Two sections of baffle safety band are formed with body by docking adhesion positioned at the hasp of upper and lower surface.
The utility model by above the safety net of existing construction cross frame at least gap adhere to two layers of baffle safety band,
And baffle safety band is to be formed by two sections of band bodies by hasp adhesion, forms catenary suspension type continuous vulcanization profile, is broken using successively absorbing, buffering
The principle of thing impact kinetic energy, the impact kinetic energy of buffering fracture material is absorbed by the adhesion strength of hasp adhesion, reduce fracture material and fall
Speed, in the case where not changing construction method original safety net can be made to be changed into fracture material directly facing fracture material impact
Born again by safety net after buffered, energy-absorbing, so as to greatly increase the resistance to scope being hit of safety net.The utility model structure
Simply, it is easy for installation, it is easy to carry, existing safety net can be effectively reduced and directly bear fracture material impact dynamics, security is more
It is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A to structural representation.
The mark and corresponding component name shown in figure be：1st, insulate carrier cable；2nd, safety net；3rd, baffle safety
Band；31st, band body；32nd, hasp.
Embodiment
This protection network of crossing over for electric transmission line erection construction of the utility model, bag are can be seen that from Fig. 1 and Fig. 2
The insulation carrier cable 1 being adjacently positioned, the safety net 2 being connected between two adjacent insulation carrier cables and some baffle safety bands 3 are included,
Each baffle safety band 3 is formed by band body 31 made of two sections of high strength fabrics by the adhesion of hasp 32, and baffle safety band 3 is laid
Above safety net 2 and at least gap is provided with two layers up and down, the end of each baffle safety band 3 with corresponding insulation carrier cable 1
It is affixed.
In the utility model, baffle safety band 3 is made up of aramid fiber.
It can be seen that in the present embodiment from Fig. 1 and Fig. 2, the baffle safety band 3 above safety net 2 has upper and lower two
Layer, the ultimate range between safety net 2 and lower floor's baffle safety band 3 are less than lower floor's baffle safety band 3 and upper strata baffle safety band 3
Between ultimate range.
Figure it is seen that two sections of upper strata baffle safety band 3 with body by the hasp positioned at upper surface to slap back to the palm
The mode of the back of the body is docked adhesion and formed, and two sections of lower floor's baffle safety band 3 with body by the hasp positioned at upper and lower surface with the centre of the palm pair
The mode of the palm back of the body is docked adhesion and formed.
