Abstract
The invention provides a scissor-type self-expansion spanning system for power transmission line live stringing. The scissor-type self-expansion spanning system includes two groups of oppositely expanding scissor-type self-expansion spanning racks arranged at the two sides of a highway and an electric railway, and a wing support for carrying leads is arranged between the two groups of scissor-type self-expansion spanning racks. The system is characterized by being simple in structure, convenient to implement, and flexible in combination, preventing the limitation of span stringing due to traffic closure, saving the cost for a large amount of span erection, reducing the span construction difficulty and improving the safety and reliably of span construction.
Description
Technical field
The present invention relates to a kind of be mainly used in overhead transmission line acrossing highway, electric railway scissor
Bootstrap leap system, belong to high-tension line crossing construction technical field.
Background technology
Compared with spanning the transmission line road, the means of transportation such as newly-built overhead transmission line acrossing highway, electric railway
Feature be：The angle of the crossing requires big（Typically require more than 60 degree）, shaft tower outer rim is to shoulder（Orbit centre）Distant
（The required distance of falling tower, and typically no less than 30 meters）, but the height crossed over is relatively low.Therefore, it is difficult to directly using leap shelves
The gate beam that sets up of two ends crossover tower itself carries rope and block device to install, and traditional Moso bamboo crossing frame is subject to frame
Body needs to set the restriction of bracing wire, and crossing construction difficulty is larger.Furthermore, during crossing construction unfolding preliminary leading rope, in order to ensure
Guide rope falls the rear safe distance with road and requires, and generally individually arranges Feng Daohou to carry out in short-term in the night traffic neutral phase.And
And after the completion of line level crossing, dismounting block frame process also needs to arrange to seal in short-term road.Therefore, traditional leap high speed side that do not have a power failure
Formula, is also actually to need to arrange at least 2 times to seal road in short-term, and the time is typically scheduled at night, also increases to construction operation
Certain difficulty.
Content of the invention
It is an object of the invention to overcoming the shortcomings of that prior art exists, and provide one kind can make full use of existing stringing and apply
Work equipment, structure is simple, easy to implement, combination is flexible, the condition that line level crossing is sealed road by traffic not only can be avoided to be limited, also may be used
Save a large amount of crossing frames and set up expense, reduce crossing construction difficulty, improve the security reliability of crossing construction, lifting is crossed at a high speed
Highway, the scissor leap system of bootstrapping of the stringing that do not have a power failure for transmission line of electricity of electrified railway construction efficiency.
The purpose of the present invention to complete by following technical solution, a kind of does not have a power failure the cutting of stringing for transmission line of electricity
Blade is bootstrapped leap system, and it is scissor that it is mainly arranged on highway by two groups, electric railway both sides can be stretched relatively
Crossing frame of bootstrapping forms, in two groups of scissor fin supports being provided between crossing frame for propping up wire of bootstrapping, described
Scissor crossing frame of bootstrapping forms scissor, wherein one secondary aluminium alloy pole bottom by hinged in the middle of two secondary aluminium alloy poles
It is articulated with one end of Horizontal type guide rail, the hinged 3rd secondary aluminium alloy pole in top, fin support, another pair are installed in shaft top
Intersect aluminium alloy pole bottom pulley and walk on Horizontal type guide rail, top pulleys walk in the 3rd secondary aluminium alloy pole bottom
Pulley guide rails on.
As preferred：Pulley on described Horizontal type guide rail is connected on motor-driven grinding mill by steel wire rope, forms closure and leads
Lead back road, and drive crossing frame to be lifted by motor-driven grinding mill rotating；On described horizontal guide rail, after crossing frame stretches and puts 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
Avoid the condition that line level crossing is sealed road by traffic to be limited, also can save a large amount of crossing frames and set up expense, reduce crossing construction difficulty,
Improve the security reliability of crossing construction, realize zero envelope road, round-the-clock crossing construction, acrossing highway, electrification can be lifted
Construction of railways efficiency about 30%.
Brief description
Fig. 1 is the scissor leap system schematic of bootstrapping that the present invention is used for overhead transmission line acrossing highway.
Fig. 2 is scissor crossing frame structural representation of bootstrapping of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1, one kind of the present invention is used for power transmission line
Road does not have a power failure the scissor leap system of bootstrapping of stringing, and it is mainly arranged on highway 1 by two groups, electric railway both sides can
The scissor crossing frame 2 of bootstrapping relatively stretching forms, two groups scissor bootstrap be provided with for propping up wire between crossing frame 2
Fin support 3.
Shown in Fig. 2, scissor crossing frame 2 of bootstrapping of the present invention is formed by hinged in the middle of two secondary aluminium alloy poles 4,5
Scissor, wherein one secondary aluminium alloy pole 4 bottom is articulated with one end of Horizontal type guide rail 6, the hinged 3rd secondary aluminum in top
Alloy pole 7, fin support 3 is installed on shaft top, and another secondary aluminium alloy pole 5 bottom pulley 8 of intersecting walks in Horizontal type
On guide rail 6, top pulleys 9 walk in the pulley guide rails 10 of the 3rd secondary aluminium alloy pole 7 bottom.
Shown in figure, the pulley 8 on Horizontal type guide rail 6 of the present invention is connected to motor-driven grinding mill 12 by steel wire rope 11
On, form closed draw loop, and drive scissor crossing frame 2 of bootstrapping to be lifted by motor-driven grinding mill 12 rotating；Described sleeping
Being provided with pulley 8 position on formula guide rail 6, after scissor crossing frame 2 stretching, extension of bootstrapping puts in place to prevent the flexible change of crossing frame
The wedge block of shape.
When the road crossed over is narrower, also line level crossing can be completed by the scissor crossing frame of bootstrapping of single group.Scissor bootstrap
Crossing frame may be designed to concatenation module, according to the spacing of different phase conductors, depending on construction condition independent assortment, is configured to multigroup
Combine and spread across frame.After line level crossing construction finishes, can integrally be condensed or split handling transport and leave the theatre.
