Description
Technical field
The present invention relates to a kind of line spanning frame, more particularly to a kind of hydraulic elevation type crossing frame.
Background technology
At this stage, when being rushed to repair or being built temporary cable and power, can often run into external cable needs to cross over horse
Road, cell doorway, the situation in passageway, typically first dig pit in such cases, then erecting electric wires in the appropriate location of road both sides
Bar, then by operating personnel climb up electric pole top carry out cable fixation and tense work.This kind of mode activity duration is long, operation
It is loaded down with trivial details, and the electric wire thick stick of temporary erection is not very firmly, to the climbing of operating personnel certain potential safety hazard to be brought sometimes.
With the extensive development and the development in an all-round way of economic society of China's power grid construction, power circuit is being built across at a high speed
The situation of the special leap such as railway, highway increases rapidly, and tension stringing crossing construction is increasingly frequent, the difficulty of crossing construction
Also increasingly increase.Meanwhile, country to safe construction work pay attention to day by day, it is desirable to step up, and crossing construction dangerous spot it is many, pacify
Full blast danger is big, electric to ensureing particular across high pressure and overpressured zones electric line, the safety and reliability of high-speed railway construction
Being smoothed out for net construction is significant with the safe operation of high-speed railway, once security incident occurs will cause larger
Economic loss and social influence.
Thing is crossed in order to protect, generally using crossing frame is built in crossing construction, at present, the truss one of crossing frame is constituted
As be steel construction, although with certain intensity, but without insulating properties, can dangerous property, or truss has insulation material
Material is made, but the intensity of truss does not just reach requirement, it is impossible to bear the load impacting of broken string, does not have protection across the work of thing
With.
Electrical network project of transmitting and converting electricity construction in, newly-built transmission line of electricity often with the ultra-high-tension power transmission line, railway for running
And the object being spanned such as highway geographically produces intersection, newly-built circuit lead wire and earth wire needs to cross object being spanned.In order to ensure this is led
Safe distance between ground wire and object being spanned, needs set up therebetween insulation safety net in advance.Safety net and its supporting
Support arrangement is referred to as crossing frame.
Crossing frame employed in current crossing construction has Moso bamboo crossing frame, cableway-type crossing frame, support body crossing frame etc..This
A little tradition crossing frames all deposit deficiency in some aspects, and such as Moso bamboo crossing frame and scaffold crossing frame is suitable for the low field of electric pressure
Close, easily limited by landform；It is light handy although the cableway-type crossing frame scope of application is very wide, because between the support of two ends span compared with
Greatly, rope road is subject to loose degree after shock loading to decline, and makes safety net and is difficult to be guaranteed by the safe distance across between object；
Support body crossing frame automatization level is low, and it installs many dependence hoisting aids instruments, and freight volume is larger, and it is not convenient enough to install.In addition
Traditional crossing frame all has that impact resistance is not enough.
Classify by execution conditions, according to the complexity that the size, importance and the enforcement that are spanned thing are crossed over, will can cross over
It is divided into three classifications：The first kind is general leap, refers to across insignificant facility and crossing frame is highly 15m and following person.Second
Class be important leap, though refer to critical facility leap and for insignificant facility crossing frame highly more than 15m person.3rd class is spy
It is different to cross over, specified according to safety, construction technical schemes must be write to special leap, important leap should be worked out by engineering department
Erection scheme, to general across without specific requirement.
Classifying by line level crossing mode to be divided into：Have a crossing frame line level crossing, crossing frame is set and capping net carry out across
More stringing.It is to make supporting mass and capping net using shaft tower to carry out line level crossing without crossing frame line level crossing.The leap of Great span
Stringing, line crossing is opened the navigation or air flight big river, lake or straits etc., because of span larger (in more than 1000m), or shaft tower it is higher (
More than 100m), conductor selection or pole and tower design need special consideration, and shipping are had a strong impact on when breaking down or is repaired especially difficult
Strain section.
Can be divided into by the classification of power circuit running status：Completely stringing over live line, that is, refer to built, lapping, opens up
Put messenger and lead, ground wire unfolding etc. in overall process operation power line do not have a power failure.Have crossing frame not have a power failure stringing, be built,
Had a power failure in short-term by across operation power line when tearing frame and block open, tearing net open, pilot rope laying, spreading lead wire and earth wire and annex installation process
Do not had a power failure across power line.Power failure stringing, that is, refer to by completely out of service across power line, recovers again after newly-built circuit stringing
Power transmission.
Can be divided into by crossing frame capping net formal classification：Not pent-roof crossing frame, it is adaptable to general to cross over and power failure frame
The leap of line.Pent-roof crossing frame, bind crossing frame of the bar with bamboo (wood) bar.Mix the crossing frame that binds with insulating cord and bamboo bar.
Bind insulation net crossing frame, and bind crossing frame for insulating cord and insulating bar (or claiming bracket-plant type).
Line level crossing is directed in line construction and frequently encounters the environment such as highway, river course, mountain area, dense population areas, such as 35KV,
Situations such as highway, building and other alive circuits are frequently encountered in 10KV, 400V construction of line work progress, existing crossing frame
Set up is affected by landform, traffic environment, population density etc., sets up difficulty, and is made troubles to traffic and resident living, is applied
Crossing frame is set up during work needs the long period, the necessary work high above the ground of workmen, must climb to leap before span line
Top of the trellis carries out fastening work to crossover track, and crossover track must again be arrived crossing frame top after crossed line and remove leap
Line, workmen's working strength is big, there is potential safety hazard, and construction is overall relatively costly.When longer across distance, there is crossover track
Surprisingly powered crossed line or the larger danger for not reaching and being spanned alive circuit safe distance of crossover track radian are dropped to,
Cause serious accident.
