In the utility model, by arranging the first lifting plate 10 and the pair of second lifting plates 20 on the main drive 1 and enabling the first lifting plate 10 and the second lifting plate 20 to be consistent with the length direction of the main drive 1, the distance between the first lifting hole 11 and the second lifting hole 21 in the central line direction of the main drive 1 is increased when the main drive 1 is in the vertical state, so that two travelling cranes can lift the main drive 1 at the same time, and the technical problem that the main drive 1 cannot be lifted by using a single travelling crane in the existing factory is solved. It should be noted that, when the crane lifts the cargo, the lifting hook and the lifting point of the crane must be vertical, i.e. the steel cable on the crane for connecting the lifting hook must be vertical. The existing main drive 1 cannot enable two traveling cranes to hoist the main drive 1 at the same time without installing the hoisting device in the utility model.
For example: one 100t+100t traveling crane (one traveling crane two trolleys, each trolley bears 100 t), one 100t+20t traveling crane (double trolleys, one bears 100t and one bears 20 t), and the rest are all small traveling cranes, and the main drive 1 is 250t, so that the main drive 1 is limited by the bearing capacity of a single traveling crane, and the conventional hoisting cannot be met in the factory. After the technical scheme of the utility model is adopted, the first lifting holes 11 and the second lifting holes 21 are respectively arranged on the first lifting plate 10 and the paired second lifting plates 20 to form three lifting points. And then lifting the main drive 1 by using 100t+100t driving and 100t+20t driving (only 100t, 20t is not used), and assembling the main drive 1 to the sub-shield block.

One end of the first reinforcing rib plate 12 is fixedly arranged on the main drive 1, the second end of the first reinforcing rib plate 12 is fixedly arranged on the first hanging plate 10, and the joint of the second end of the first reinforcing rib plate 12 and the first hanging plate 10 is positioned between the first end and the second end of the first hanging plate. By providing the first reinforcing rib plate 12, the load capacity of the first hanger plate 10 can be greatly improved, and the safety in the hanging process can be increased.
Further, a first mounting plate 13 is fixedly arranged at the first end of the first hanging plate 10, the first mounting plate 13 is mounted on the circumferential side surface of the main drive 1, a plane can be milled on the circumferential side surface of the main drive 1 for mounting the first mounting plate 13, and the first mounting plate 13 and the main drive 1 can be fixedly connected through fasteners. The first mounting plate 13 is provided between the first hanger plate 10 and the main drive 1, so that the first hanger plate 10 can be more firmly mounted on the main drive 1.
Further, a second mounting plate 22 is fixedly provided at the first end of the second hanger plate 20, and the second mounting plate 22 is fixedly mounted on the end face of the main drive 1. The second mounting plate 22 is further provided with a second reinforcing rib plate 23, one end of the second reinforcing rib plate 23 is fixedly arranged on the second mounting plate 22, and the second end of the second reinforcing rib plate 23 is fixedly connected with the second hanging plate 20. The connection mode of the second mounting plate 22 and the main drive 1 can be consistent with the connection mode of the first mounting plate 13 and the main drive 1, and the second mounting plate 22 and the second reinforcing rib plate 23 can improve the load capacity of the second lifting plate 20 and increase the safety in the lifting process.
Further, a connection plate 24 is provided between the pair of second hanger plates 20, and the connection plate 24 is used to connect the two second mounting plates 22. By connecting the two second hanger plates 20 via the connecting plate 24, the bending resistance of the second hanger plates 20 can be increased.
Finally, the main drive 1 hoisting apparatus further includes anti-tilt plates 30 provided in pairs, the anti-tilt plates being provided on circumferential sides of the main drive 1, and the pair of anti-tilt plates 30 being symmetrical with respect to the first hoisting plate 10, the anti-tilt plates 30 being capable of supporting the main drive 1 such that a center line of the main drive 1 is in a horizontal direction. When the first hanging plate 10 and the second hanging plate 20 are installed on the main drive 1, the main drive 1 is in an upright state, no travelling crane is hung at the moment, the main drive 1 is easy to slide or incline, and the anti-incline plate 30 is arranged on the circumferential side surface of the main drive 1, so that the main drive 1 can be ensured to be firmer when being upright.
Specifically, the main drive 1 hoisting device further comprises an anti-tilt support plate 33. The side edge of the anti-tilting plate 30 far away from the main drive 1 comprises an arc section 31 and a straight line section 32 which are connected with each other, the anti-tilting support plate 33 is arranged on the anti-tilting plate 30 and is positioned at the arc section 31, and one side edge of the anti-tilting support plate 33 is positioned on the same horizontal plane as the straight line section 32 (when the main drive 1 is in an upright state, the one side edge of the anti-tilting support plate 33 and the straight line section 32 of the anti-tilting plate 30 play a role in supporting the main drive 1). As shown in fig. 3, when the center line of the main drive 1 is in a vertical state, the main drive 1 is in a state to be turned over, and the anti-tilting plate 30 is mounted on the main drive 1, so that the driving can find out 90-degree turning over of the main drive 1. When the main drive 1 is in an upright state (i.e., the end surface landing of the main drive 1 becomes the circumferential side surface landing of the main drive 1), the arc-shaped section 31 on the side edge of the anti-roll plate 30 can make the turning-over process of the main drive 1 smoother. As shown in fig. 4, after turning over of the main drive 1 is completed, the lifting hook of the travelling crane is not loosened first, then the anti-tilting support plate 33 is installed on the main drive 1, and finally the lifting hook of the travelling crane is loosened, and the main drive 1 can be firmer in the standing state under the support of the anti-tilting plate 30 and the anti-tilting support plate 33.
