As further technical scheme of the present invention: in this power distribution rod tower identification board special-purpose ladder, the groove floor on described cross-arm is horizontal plane.
In this power distribution rod tower identification board special-purpose ladder, the groove two sides on described cross-arm are perpendicular and are parallel to each other.
In this power distribution rod tower identification board special-purpose ladder, inside the concave surface of described arc, be fixedly installed slipmat.
The invention has the beneficial effects as follows: need not two people hold the ladder when it uses, ladder can be fixed voluntarily, thus save artificial, and can not shake, safety is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further:
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the assembling schematic diagram of seat board, bolt, ground nail in Fig. 1;
Fig. 4 is that the A of anchor ear in Fig. 1 is to schematic diagram;
Fig. 5 is that the B of arc in Fig. 1 is to schematic diagram;
In figure: 1 main strut, 2 cross-arms, 21 grooves, 3 arcs, 31 slipmat, 4 bases, 41 seat boards, 42 through holes, 43 bolts, 431 thread segments, 432 smooth section, 433 conical sections, 5 clamp nuts, 6 ground nails, fixed bar bottom 7,8 anchor ears.
Detailed description of the invention
As shown in Figure 1, 2, this power distribution rod tower identification board special-purpose ladder, comprise main strut 1, multiple cross-arm 2, described cross-arm 2 is provided with two row, and the symmetrical both sides being fixed on main strut 1, the upper surface of described cross-arm 2 is provided with groove 21.In this embodiment, the bottom surface of the groove 21 on cross-arm is horizontal plane, and the two sides of groove 21 are perpendicular and are parallel to each other.
At least one arc 3 is provided with, the central axis of arc 3 and the axis being parallel of main strut 1 and main strut 1 is positioned at the middle part on arc 3 length direction on the top of main strut 1.In this power distribution rod tower identification board special-purpose ladder, be fixedly installed slipmat 31 inside the concave surface of described arc, as shown in Figure 5.
The bottom of main strut 1 is provided with base 4, and base 4 comprises the both sides being positioned at main strut 1 of two seat boards, 41, two seat board 41 symmetries and vertical with cross-arm 2, one end of seat board 41 and the otic placode of main strut 1 bottom hinged, the other end of seat board 41 is provided with through hole 42, a bolt 43 is provided with in through hole 42, as shown in Figure 3, bolt 43 comprises thread segment 431 and smooth section 432, conical section 433, smooth section 432 is between thread segment 431 and conical section 433, bolt 43 is through the through hole 42 on seat board, and be equipped with clamp nut 5 at thread segment 431, clamp nut 5 is pressed on seat board 41 upper surface, bolt 43 is provided with endoporus, through there being ground nail 6 in endoporus, the bottom of ground nail 6 is taper and is exposed to outside the conical section 433 of bolt, the length of ground nail 6 is greater than the length of bolt 43.
On main strut 1 by otic placode hinged be provided with bottom fixed bar 7, the other end of bottom fixed bar 7 arranges and is fixedly connected with anchor ear 8, as shown in Figure 4.
During use, first main strut is placed on working position, arc is stuck on line bar, and the gradient of adjustment main strut, makes the height on top more suitable, then anchor ear 8 is fixed the bottom of online bar.Again the seat board 41 of base 4 is opened, first fix a seat board, ground is inserted total after first bolt 43 being passed the through hole 42 of seat board when fixing this seat board, because bolt 43 bottom is conical section 433, therefore can in insertion ground, more smooth labour-saving, again clamp nut 5 is assemblied on the thread segment 431 of bolt, makes the compression seat board 41 of clamp nut 5 on ground, then by insertion ground also finally fastening in the endoporus of ground nail 6 inserting bolt; Finally fix another one seat board more in the same way on ground.Namely special-purpose ladder fixedly completes, and stablize and do not rock, it is also very safe that not employment buttresses climbing.Can not topple over.And groove 21 on cross-arm can well the foot of personnel on fixed bar, thus the phenomenon of landing can not be there is, ensure the safety of staff further.
