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 end positions of elongated slot 14
Limited block 22 is set 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 two ends in cross rail inner, it is therefore an objective to which pair roller is played
Position-limiting action, adds processing safety；And anti-skid bulge is set in cell cube medial surface, it is therefore an objective to increase cell cube 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, is afterwards sling power equipment by pulling lifting cucurbit, chain block is slow transitted through afterwards makes crossbeam left end highly
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
The power equipment sling is moved to behind left side by elongation, mechanism to be lifted, and the traction end of left chain block is fixed on into lifting machine
The left side of structure is simultaneously tensed to prevent that derricking gear from moving left and right, and adjusts level by tensing upper chain block by crossbeam afterwards, with
Power equipment is put down by pulling lifting cucurbit afterwards, that is, completes the unloading of power equipment；Then power equipment can just be entered
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, 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 and how to be lifted by crane
The right side of mechanism is simultaneously tensed to prevent that 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 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.
