Because the transformer is heavy, the site geographical position is often not ideal, and the terrain is rugged and uneven, and the lifting under the condition of complex terrain and the strength of the lifting device need to be considered during the design, the lifting is reliable and safe. The invention fundamentally solves the problem of hoisting the transformer. Meanwhile, the structure is innovated, and the use is more convenient.
Before use, the invention in the folded state of fig. 4 is transported to the transformer site where it is to be installed and then unfolded according to fig. 3.
As another use method of the invention, the invention can open the telescopic assembly, place the transformer on the working platform 16 as a transformer transportation tool, and the open telescopic assembly can be used as a push-pull handle, as shown in figure 5.
The unfolding process of the invention comprises the following steps: the telescopic assembly is opened upwards, and the included angle between the control and the working platform 16 is smaller than 90 degrees; then the folding component is unfolded, and the bayonet 6 is inserted into the bayonet fixing hole of the folding rod rotating shaft mechanism 5, so that the folding rod 3 and the second-stage telescopic rod 10 are prevented from rotating accidentally during working; at this time, the working platform is pushed to the middle of two electric poles, the bottom telescopic rod 18 and the top telescopic rod 2 of the working assembly are opened, so that the bottom telescopic rod 18 and the top telescopic rod 2 are respectively arranged on two sides of the electric poles, and then an operator installs the zipper block on the block hanging buckle 101; finally, a field operator shakes the manual winch 17 to contract the first-stage steel wire rope 13, so that the first-stage fixed pulley block 1401 and the second-stage movable pulley block 1002 are shortened, and the second-stage telescopic rod 10 moves upwards; meanwhile, as the second-stage telescopic rod 10 moves upwards, the upper horizontal bar of the second-stage telescopic rod 10 rises, namely, the distance between the upper horizontal bar of the second-stage telescopic rod 10 and the upper horizontal bar of the first-stage telescopic rod 14 is enlarged, so that the third-stage telescopic rod 7 is driven to move upwards; when the manual winch 17 is retracted to complete the first stage of the wire rope 13, the working assembly peaks.
The working state is shown in fig. 6, after the transformer is connected with the chain block, the chain block is pulled to lift the transformer to a specified height, and then the transformer is fixed between two electric poles; when the transformer is fixed, the front, the back, the left and the right positions of the transformer can be controlled by installing a traction rope on the transformer, so that the transformer is installed in the middle of two electric poles, and the figure 7 shows.
The stress analysis of the invention is shown in figure 8, when the invention works, a heavy object G (namely a transformer) bears the vertical downward gravity, and because the included angle between the telescopic component and the working platform 16 is less than 90 degrees, the top telescopic rod 2 of the invention applies right pressure to two electric poles; the bottom telescopic rod 18 of the present invention applies a leftward pressure to the two poles, so that the present invention can achieve a horizontal balance, and particularly, when the heavy object G (i.e., the transformer) is heavier, the present invention has a greater friction force to the two poles, and the present invention is more stable.
In the use, can also dismantle gyro wheel 1601 for work platform 1's whole bottom surface contact ground reduces the pressure to ground, avoids gyro wheel 1601 to sink into in the ground.
The first-stage telescopic rod 14, the second-stage telescopic rod 10 and the third-stage telescopic rod 7 are all hollow structures, and the cross section sizes are gradually increased and are respectively sleeved; the ball sliding block 8 is arranged in the gap between every two telescopic rods, so that the friction force during stretching is reduced.

The telescopic assembly is connected with the rotating shaft 15 to control the telescopic assembly to be unfolded and control an included angle between the foldable assembly and the working platform 16 to be unfolded.
Folding pole pivot mechanism 5 control folding assembly expandes, and bayonet lock 6 is used for folding assembly to expand when targetting in place, inserts the dead angle of end of inserting card.
When the telescopic link extension targets in place, the fixed buckle 12 card of control telescopic link is dead, prevents that telescopic component from returning.
When the top pole 2 and the bottom pole 18 rest on the pole, the slip-resistant rubber boot 4 prevents the top pole 2 and the bottom pole 18 from slipping on the pole.
The invention is matched with the lifting arm, so that the multi-point suspension of the transformer can be realized, the aims of 1 person lifting operation, 1 person monitoring and 1 person commanding are achieved, the operating personnel are reduced, and the operation risk is reduced. Meanwhile, the hoisting process is controllable, the transformer has no contact rod and falling risk, and the method is safe and efficient.
At present, according to the intelligent power grid construction planning of a national power grid company, innovative power tools and appliances are correspondingly popularized, the method can be popularized in 26 power distribution networks of provincial, autonomous and direct administration cities in a national power grid company system, the project achievement has a great effect on power distribution operation inspection and repair, and the application range is very wide. The invention improves the working efficiency of platform area installation and has great social and economic significance.
