Description
Technical field
The present invention relates to it is a kind of be mainly used for overhead transmission line acrossing highway, electric railway it is scissor
Bootstrap across system, belongs to high-tension line crossing construction technical field.
Background technique
Compared with spanning the transmission line road, the means of transportation such as overhead transmission line acrossing highway, electric railway are created
The characteristics of be: the angle of the crossing requires big (generally requiring 60 degree or more), and shaft tower outer rim to shoulder (orbit centre) distance is farther out
(required distance of falling tower, and typically no less than 30 meters), but the height crossed over is relatively low.Shelves are crossed over therefore, it is difficult to directly utilize
Both ends crossover tower itself sets up gate beam to install carrying rope and block device, and traditional Moso bamboo crossing frame is by frame
Body needs to set the limitation of bracing wire, and crossing construction difficulty is larger.Furthermore when crossing construction unfolding preliminary leading rope, in order to ensure
Guide rope falls the safe distance requirement with road afterwards, generally arranges Feng Daohou to carry out in short-term in the night traffic neutral gear phase.And
And after the completion of line level crossing, disassembly block frame process also needs to arrange to seal in short-term.Therefore, traditional leap high speed side that do not have a power failure
Formula actually and needs to arrange at least 2 times and seals in short-term, and the time is typically scheduled at night, also construction operation is given to increase
Certain difficulty.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and providing a kind of can make full use of existing stringing to apply
Work equipment, structure is simple, easy to implement, combination is flexible, not only can avoid line level crossing and is limited by the condition in traffic envelope road, may be used also
It saves a large amount of crossing frames and sets up expense, reduce crossing construction difficulty, improve the security reliability of crossing construction, promoted across high speed
Highway, electrified railway construction efficiency are bootstrapped across system for transmission line of electricity the scissor of stringing that do not have a power failure.
The object of the present invention is achieved by the following technical solutions, and a kind of stringing that do not have a power failure for transmission line of electricity is cut
Blade is bootstrapped across system, it mainly by two groups be mounted on highway, electric railway two sides can opposite stretching, extension it is scissor
Crossing frame of bootstrapping composition, is equipped with the finned bracket for propping up conducting wire between two groups of scissor crossing frames of bootstrapping, described
Scissor crossing frame of bootstrapping is by hingedly forming scissor among two secondary aluminium alloy poles, wherein a secondary aluminium alloy pole bottom end
It is articulated with one end of Horizontal type guide rail, the hinged third pair aluminium alloy pole in top, finned bracket, another pair are installed in shaft top
Intersect aluminium alloy pole bottom pulley to walk on Horizontal type guide rail, top pulleys walk in third pair aluminium alloy pole bottom
Pulley guide rails on.
As preferred: the pulley on the Horizontal type guide rail is connected on motor-driven grinding mill by wirerope, is formed closure and is led
Road is led back, and drives crossing frame to be gone up and down by motor-driven grinding mill positive and negative rotation；On the horizontal guide rail, after crossing frame stretching, extension in place
Pulley position at be provided with the wedge block that can prevent crossing frame dilatation.
The present invention can make full use of existing Poling Construction equipment, and structure is simple, easy to implement, combination is flexible, not only may be used
It avoids line level crossing from being limited by the condition in traffic envelope road, can also save a large amount of crossing frames and set up expense, reduce crossing construction difficulty,
The security reliability of crossing construction is improved, zero envelope road, round-the-clock crossing construction is realized, acrossing highway, electrification can be promoted
Construction of railways efficiency about 30%.
Detailed description of the invention
Fig. 1 is that the present invention bootstraps for the scissor of overhead transmission line acrossing highway across system schematic.
Fig. 2 is scissor crossing frame structural schematic diagram of bootstrapping of the present invention.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: of the present invention a kind of for power transmission line shown in Fig. 1
Road the scissor of stringing that do not have a power failure is bootstrapped across system, it is mainly mounted on highway 1 by two groups, electric railway two sides can
The scissor composition of crossing frame 2 of bootstrapping of opposite stretching, extension, is equipped between two groups of scissor crossing frames 2 of bootstrapping for propping up conducting wire
Finned bracket 3.
Shown in Fig. 2, scissor crossing frame 2 of bootstrapping of the present invention among two secondary aluminium alloy poles 4,5 by hingedly forming
Scissor, wherein secondary 4 bottom end of aluminium alloy pole is articulated with one end of Horizontal type guide rail 6, the hinged third pair aluminium in top
Finned bracket 3 is installed on alloy pole 7, shaft top, and another secondary 5 bottom pulley 8 of aluminium alloy pole of intersecting walks in Horizontal type
On guide rail 6, top pulleys 9 are walked in the pulley guide rails 10 of 7 bottom of third pair aluminium alloy pole.
As shown in the figure, the pulley 8 on Horizontal type guide rail 6 of the present invention is connected to motor-driven grinding mill 12 by wirerope 11
On, closed draw circuit is formed, and drive scissor crossing frame 2 of bootstrapping to be gone up and down by 12 positive and negative rotation of motor-driven grinding mill；It is described sleeping
Being provided on formula guide rail 6, at 8 position of pulley after the scissor stretching, extension in place of crossing frame 2 of bootstrapping, which can prevent crossing frame from stretching, becomes
The wedge block of shape.
When the road of leap is relatively narrow, line level crossing can also be completed by the scissor crossing frame of bootstrapping of single group.It is scissor to bootstrap
Crossing frame may be designed to splicing module, according to the spacing of different phase conductors, is freely combined depending on construction condition, is configured to multiple groups
Combine and spreads across frame.After line level crossing is constructed, integrally it can be condensed or split handling transport and leave the theatre.
