Embodiment two:
As shown in figure 5, the difference of itself and embodiment one is:The upper end circumference of tapering point cap 8 sets block 21.
The inside of anchor ear 6 sets skid resistant course.
In the embodiment, block is set in tapering point cap upper end edge circumference, annular briquetting can be prevented from tapering point cap
Upper end comes off, and is easy to carry while adding processing safety;Skid resistant course is set inside anchor ear, so as to increase anchor ear
Frictional force between electric pole, make what anchor ear more fastened to be connected with electric pole, to play a part of supporting fixed cross beam right-hand member.
Embodiment three:
As shown in Figure 6 and Figure 7, it is with the difference of embodiment two:The inner side of crossbeam 1 is close to the both ends of elongated slot 14
Position sets limited block 22 respectively.
The medial surface of cell cube 82 sets anti-skid bulge 23.
In the embodiment, limited block is set on the position at elongated slot both ends in cross rail inner, it is therefore an objective to which pair roller plays
Position-limiting action, add processing safety;And anti-skid bulge is set in cell cube medial surface, it is therefore an objective to increasing unit body and electric pole
Between frictional force, cell cube is more firmly connected with electric pole.
Power equipment is hung oneself from electric pole unload down when, crossbeam is fixed on by power equipment both sides by hold-fast body
On electric pole, then tapering point cap be located in the top of power equipment both sides electric pole, and crossbeam is adjusted by upper chain block
Level, power equipment is sling by pulling lifting cucurbit afterwards, slow transitting through chain block afterwards makes crossbeam left end height
Slightly below right-hand member, now right chain block pull derricking gear, then slowly make the traction end of right chain block lower section to the left
Elongation, after the power equipment sling is moved to left side by mechanism to be lifted, the traction end of left chain block is fixed on lifting machine
The left side of structure is simultaneously tensed to prevent derricking gear from moving left and right, and crossbeam is adjusted into level by tensing upper chain block afterwards, with
Power equipment is put down by pulling lifting cucurbit afterwards, that is, completes the unloading of power equipment;Then can is entered to power equipment
Row site examining and repairing.Opposite, when the power equipment overhauled is lifted on electric pole, first by the traction end of left chain block
It is fixed on derricking gear, plays power equipment by pulling lifting hoist afterwards, afterwards by tensing upper chain block by horizontal stroke
Beam left end raises and crossbeam left end is slightly above crossbeam right-hand member, then the traction end of left chain block is stretched to the right
It is long, when power equipment to be moved to the electric pole position on right side for mechanism to be lifted, the traction end of right chain block is fixed on lifting
The right side of mechanism is simultaneously tensed to prevent derricking gear from horizontally slipping, and crossbeam is adjusted into level by upper chain block afterwards, then
Power equipment is placed on the cross-arm on electric pole by pulling lifting cucurbit, that is, completes the lifting to power equipment.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common
Other modifications or equivalent substitution that technical staff is made to technical scheme, without departing from technical solution of the present invention
Spirit and scope, all should cover among scope of the presently claimed invention.
