Second partial gear 5, the second partial gear 5 are coaxially fixed with the first lead screw 6, and 6 right end of the first lead screw is coaxially fixed with the
The thread rotary orientation of two lead screws 7, the first lead screw 6 and the second lead screw 7 is on the contrary, the first lead screw 6 is threaded with the first nut 8, and second
Lead screw 7 is threaded with the second nut 9, and the first nut 8 and the second nut 9 are equipped with through-hole, wirerope 3 and through-hole through company
It connects, 3 lower end of wirerope slidably connects pulley 10, and pulley 10 is hinged with hook 11；
1 upper end of shell is fixedly connected with walking dolly, and walking dolly includes first motor 12, and first motor 12 is fixed with
One gear 13, first gear 13 are engaged with second gear 14, and second gear 14 is coaxially fixed with the first traveling wheel 15, the first walking
Wheel 15 rolls and is connected with I-steel 16, the rolling of I-steel 16 be connected with symmetrical second traveling wheel 17 of the first traveling wheel 15, the
Two traveling wheels 17 are coaxially fixed with third gear 18, and third gear 18 is engaged with the 4th gear 19, and the 4th gear 19 is fixed with
Two motors 20.
The transmission shaft 2 is fixedly connected with third motor 21.
First nut 8 and the second nut 9 slidably connects guide rail 22.
First lead screw 6 is equipped with round bump, limits to the first nut 8 and the second nut 9.
When the utility model is used, first motor 12 is associated with starting with the second motor 20 simultaneously, first gear 13 is driven
Second gear 14 rotates, and second gear 14 drives the first traveling wheel 15 to roll on I-steel 16, and similarly, third gear 18 drives
The rotation of 4th gear 19, the 4th gear 19 drive the second traveling wheel 17 to roll on I-steel 16, the first traveling wheel 15 and second
