The middle part of diameter parallel and main strut on arc length direction；The bottom of main strut is provided with base, and base includes two
Individual seat board, two seat boards are symmetrically located in both sides of main strut and vertical with cross-arm；One end of seat board and the ear of main strut bottom
Plate is hinged, and the other end of seat board is provided with through hole, and a bolt is provided with through hole, and bolt includes thread segment and smooth section, taper
Section, smooth section are located between thread segment and conical section, and bolt is through the through hole on the seat board, and is equipped with fastening in thread segment
Nut, clamp nut are pressed on seat board upper surface, and bolt is provided with endoporus, and through there is ground nail in endoporus, the bottom of ground nail is cone
Shape and it is exposed to outside the conical section of bolt, the length of the length of ground nail more than bolt；The setting being hinged by otic placode on main strut
There is bottom fix bar, the other end of bottom fix bar is arranged and is fixedly connected with anchor ear.
As the further technical scheme of the present invention：It is in the power distribution rod tower identification board special-purpose ladder, recessed on the cross-arm
Groove bottom is horizontal plane.
In the power distribution rod tower identification board special-purpose ladder, the groove two sides on the cross-arm are perpendicular and are parallel to each other.
In the power distribution rod tower identification board special-purpose ladder, on the inside of the concave surface of the arc, slipmat is fixedly installed.
The invention has the beneficial effects as follows：It using when hold the ladder without two people, ladder voluntarily can be fixed, so as to save
Manually, and will not shake, safety is good.
Description of the drawings
The present invention is described further with reference to the accompanying drawings and examples：

Fig. 4 is the A of anchor ear in Fig. 1 to schematic diagram；
Fig. 5 is the B of arc in Fig. 1 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 spiral shells
Bolt, 431 thread segments, 432 smooth sections, 433 conical sections, 5 clamp nuts, 6 ground nails, 7 bottom fix bars, 8 anchor ears.
Specific embodiment
As shown in Figure 1, 2, the power distribution rod tower identification board special-purpose ladder, including main strut 1, multiple cross-arms 2, the cross-arm 2 set
Two row are equipped with, the symmetrical both sides for being fixed on main strut 1, the upper surface of the cross-arm 2 arrange fluted 21.In the 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.
The top of main strut 1 is provided with least one arc 3, the central axis of arc 3 and the axis of main strut 1
Parallel and main strut 1 is located at the middle part on 3 length direction of arc.In the power distribution rod tower identification board special-purpose ladder, the arc
Concave surface on the inside of be fixedly installed slipmat 31, as shown in Figure 5.
The bottom of main strut 1 is provided with base 4, and base 4 includes two seat boards 41, and two seat boards 41 are symmetrically located in main
Both sides of bar 1 and vertical with cross-arm 2；One end of seat board 41 is hinged with the otic placode of 1 bottom of main strut, and the other end of seat board 41 is arranged
There is through hole 42, a bolt 43 is provided with through hole 42, as shown in figure 3, bolt 43 includes thread segment 431 and smooth section 432, taper
Section 433, smooth section 432 are located between thread segment 431 and conical section 433, and bolt 43 passes through the through hole 42 on seat board, and in screw thread
Section 431 is equipped with clamp nut 5, and clamp nut 5 is pressed on 41 upper surface of seat board, and bolt 43 is provided with endoporus, passes through in endoporus
The bottom for having ground nail 6, ground nail 6 is taper and is exposed to outside the conical section 433 of bolt that the length of ground nail 6 is more than the length of bolt 43
Degree.
Bottom fix bar 7 is provided with by what otic placode was hinged on main strut 1, the other end of bottom fix bar 7 is arranged to be fixed
Anchor ear 8 is connected with, as shown in Figure 4.
During use, main strut is placed on into working position first, arc is stuck in line bar, adjusts the gradient of main strut, make
The height on top is more suitable, and then anchor ear 8 is fixed on the bottom of line bar.Again the seat board 41 of base 4 is opened, one is first fixed
Bolt 43 is first always inserted ground through after the through hole 42 of seat board when fixing the seat board by seat board, as 43 bottom of bolt is taper
Section 433, therefore can compare in smooth labour-saving insertion ground, then clamp nut 5 is assembled on the thread segment 431 of bolt, make
The compression seat board 41 of clamp nut 5 on ground, then in during ground nail 6 to be inserted the endoporus of the bolt and insertion ground that finally fastens；
Finally another seat board is fixed again in the same way to ground.Special-purpose ladder i.e. fixation is completed, stable not rock, not employment
Buttress climbing also very safe.Will not topple over.And the groove 21 on cross-arm can be very good the foot of personnel in fix bar, from
Without the phenomenon for occurring to slide, the safety of staff is further ensured that.
