Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the present apparatus is used for the erection of power transmission line 28, and direction A is moved towards as front using power transmission line 28
To, the present apparatus includes pedestal 6, column 7, left support arm 17 and right support arm 25, and multiple drawing ground wire anchor ears 1 are arranged with pedestal 6,
Bolt connection has pivoting support 5 on pedestal 6, and pendulum 3, the pendulum are rotatably connected to by the first bearing pin 2 on pivoting support 5
Piece 3 passes through the second bearing pin（Do not drawn in figure）It is connected with the lower rotation of column 7, can clearly determines very much as shown in Figure 1
The axis of first bearing pin 2 and the axis of the second bearing pin are vertical, and such column 7 is achieved that cross swing；The column 7
It is connected in sequence from bottom to top by multiple standard knots 10, multiple drawing ground wire anchor ears 8 is surrounded by the upper end of column 7,
The lower end of the left support arm 17 and right support arm 25 is symmetrically hinged on the middle and upper part of 7 corresponding left surface of column and right flank, on a left side
The upper end of support arm 17 and right support arm 25 is equipped with drawing ground wire anchor ear 19, track cable directive wheel 18 and the support arm drag-line 21,24；
As shown in Figures 2 and 3, inverted trapezoidal support frame 9 is fixed with the top of column 7, in order to prevent power transmission line 28 from being damaged after dropping
The present apparatus is rotatably connected to horizontally disposed roller 13, axis and the left side of the roller 13 at the top of inverted trapezoidal support frame 9
Right direction is parallel, is provided with left wheel 11 in the left upper end of inverted trapezoidal support frame 9, is set in the upper right side of inverted trapezoidal support frame 9
There is right roller 14, left directive wheel 12, right directive wheel are provided with the centre of inverted trapezoidal support frame 9（Be blocked no label）And institute
State track cable directive wheel 16；The free end of support arm drag-line 21 of the left support arm 17 sequentially passes through left wheel 11 and left directive wheel 12 is stretched
Anchor downwards on the ground, the free end of support arm drag-line 24 of the right support arm 25 sequentially passes through right roller 14 and right directive wheel is stretched
Anchor downwards on the ground, it is left in order to increase steadiness when angle needed for left support arm 17 and right support arm 25 are rotated upwardly into
Reinforced pull rod 20 is respectively connected between the upper end and inverted trapezoidal support frame 9 of support arm 17 and right support arm 25.
As shown in figure 5, in use, direction A is moved towards in the both sides point for being spanned barrier 32 first along power transmission line 28
Not Gu Ding the present apparatus, using draw ground wire 33,34,27 it is upper with pedestal, the upper end of column 7, left support arm 17 and right support arm 25 respectively
Then the connection of drawing ground wire anchor ear 1,8,19 at end is led so as to which the present apparatus be securely fixed on the ground in two left support arm track cables
Connect respectively between rope directive wheel between wheel, between two right support arm track cable directive wheels, in two inverted trapezoidal support frames 9
It is connected to the first track cable 26, the second track cable 29, the 3rd track cable 31, first track cable 26, the second track cable the 29, the 3rd
The both ends anchoring of track cable 31 on the ground, is laid between the first track cable 26, the second track cable 29, the 3rd track cable 31
Capping net 30, because the height of the 3rd track cable 31 is less than the height of the first track cable 26 and the second track cable 29, thus shape
Into the capping net 30 of a V-type, barrier 32 is spanned so as to be unlikely to damage when ensure that power transmission line 28 drops.
The existing single column maximum in country span of screening only has 6 meters, because the left support arm 17 and right support arm 25 of the present apparatus can
To stretch its span up to 12 meters；Column 7 can by increase and decrease the number of standard knot 10 adjust its convenient height of high speed operation can
Up to 50 meters；Contacted first with capping net 30 when power transmission line 28 drops, then contacted with roller 13 and be further slipped to capping net
Bottom 30 improves the high impact-resistant of the present apparatus, it is achieved thereby that a kind of column quantity is few, span is big, it is safe, more pass through
