Description
Technical field
The present invention relates to a kind of pay-off crossing frame, more particularly, to a kind of portable pay-off crossing frame.
Background technology
During power circuitry engineering is built, there is substantial amounts of crossing elimination and cross over, such as connection, 0.4kV low-voltage lines, 10kV lines
Road etc..In face of handing over across when construction team often to adopt with the following method：(1) crane auxiliary construction；(2) crossing frame construction is set up；(3) stop
Constructed after electrical ground with ladder or other servicing units；(4) by crossed line it is on the ground after construct again.
In place of the equal Shortcomings of four kinds of construction methods of the above.
(1) it is more convenient during crane auxiliary construction but costly, limited seriously by road.
(2) crossing frame construction is pretty troublesome, is that personnel must have card first, next is wasted time and energy.In face of handing over across more line
When road is constructed, expense is high.
(3) have a power failure also pretty troublesome with ladder or the construction of other servicing units after being grounded, power failure should be reported to plan, needed again
Safety measure is done after power failure, safety measure also needs to the cooperation of other servicing units such as ladder, support etc. after carrying out, overall next
Say to be also to waste time and energy.When it is 0.4kV families on line to hand over cross-line road, due to needing peeling hanging earthing conductor, during this period of time people
There is potential safety hazard without ground protection, construction in member.
(4) mode that crossed line is constructed again after on the ground, needs to transform crossed line, after construction also before construction
It must recover, more cumbersome, expense is higher.
The content of the invention
The purpose of the present invention is to overcome the not enough movable type rational in infrastructure, safe and reliable there is provided one kind of the prior art
Pay-off crossing frame.
This portable pay-off crossing frame, including the first main support and the second main support；First main support is by stretching
Contracting bar is in first base, and second main support is by expansion link in second base；The left end of first main support is set
There is first pulley, right-hand member is provided with horn mouth, top provided with guiding clamping bar；Second main support left end is provided with tip, and provided with oblique
Groove；The expansion link that first base is provided with rolled round, first base is provided with second pulley；There is steel ball in the end system of lightweight rope,
Lightweight rope sequentially passes through rolled round, second pulley and is oriented to clamping bar；It is just right that horn mouth and tip are worked in coordination, and the upper left of groove is rectified
To steel ball, the bottom righthand side of groove is provided with the right side of the 3rd pulley and the expansion link positioned at the second main support.
As preferred：The junction of first main support and the second main support and expansion link is equipped with diagonal brace, the first bottom
Discus is equipped with seat and second base.
The beneficial effects of the invention are as follows：Present apparatus cost of manufacture is not high, and use cost is not also high, with loop wheel machine, crossing frame etc.
Compare, time saving and energy saving save money of saving trouble.It can realize and be not required to have a power failure by friendship cross-line road, be not required to do safety measure, be not required to transform, constructed
Journey does not need big machinery, will greatly save engineering construction time, reduction expense, improves efficiency.

Embodiment
The present invention is described further with reference to the accompanying drawings and examples.Although the present invention will enter with reference to preferred embodiment
Row description, it should be understood that being not offered as limiting the invention in the embodiment.It can be included on the contrary, the present invention will cover
Alternative, modified and the equivalent in the scope of the present invention that appended claims is limited.
As shown in Figures 1 to 4, this portable pay-off crossing frame, including the first main support 8 and the second main support 9；It is described
First main support 8 is by expansion link 5 in first base 1, and second main support 9 is located at second base 2 by expansion link 5
On；The left end of first main support 8 is provided with first pulley 6, and right-hand member is provided with horn mouth 13, top provided with guiding clamping bar 11；Second master
The left end of support 9 is provided with tip 12, and provided with oblique groove 10；First base 1 is provided with the expansion link in rolled round 3, first base 1
5 are provided with second pulley 16；There is steel ball 15 in the end system of lightweight rope 14, and lightweight rope 14 sequentially passes through rolled round 3, second pulley 16 and led
To clamping bar 11；It is just right that horn mouth 13 and tip 12 are worked in coordination, and the upper left of groove 10 is rectified to steel ball 5, and the bottom righthand side of groove is set
