Because large-scale ball mill's size is big, the weight is heavy, in order to guarantee this installation device's stability and reliability, bearing structure and motor's size is also inevitable great, weight is heavier, not only needs great installation space so that the installation of bearing structure and motor, has increased this installation device's whole size, but also greatly increased this installation device's manufacturing cost, made this installation device's economic nature relatively poor.
In order to reduce the manufacturing cost of the installation device and improve the economy, the lifting platform 4 preferably includes a horizontally disposed bottom plate 41, a horizontally disposed top plate 42 disposed above the bottom plate 41, and a plurality of horizontally disposed support beams 43 fixed between the bottom plate 41 and the top plate 42.

In the above embodiment, although the rotating plate 51 needs to overcome the friction between the rotating plate 51 and the supporting beam 43 and the friction between the rotating plate 51 and the inner wall of the circular hole 44 of the top plate 42 during the rotation, this structure can reduce the size of the whole mounting device, greatly reduce the manufacturing cost, and improve the economy.

Preferably, the latch hole 53 is provided at the bottom of the guide groove 52.
In the above embodiment, when the second driving mechanism drives the rotation plate 51 to rotate, the guide block 62 and the latch 63 will bear a certain horizontal shearing force, thereby reducing their service life.

After the position of the saddle 61 is adjusted, the bolt 63 on the saddle 61 is inserted into the bolt hole 53, so that the position of the saddle 61 is locked, then the shear key on the saddle 61 is inserted into the shear groove 54, and the shear groove 54 is matched with the shear key to resist the horizontal shearing force at the bottom of the saddle 61, so that the guide block 62 and the bolt 63 are prevented from bearing the horizontal shearing force, and the service life of the guide block 62 and the bolt 63 is prolonged. The second driving mechanism is used for driving the rotary plate 51 to rotate, so that the angle of the large-scale ball mill on the horizontal plane is changed. The second driving mechanism comprises a second hydraulic cylinder 14 which is horizontally arranged; the cylinder body of the second hydraulic cylinder 14 is movably connected with the top plate 42, and the piston rod of the second hydraulic cylinder 14 is movably connected with the support 6.

In operation, the lower right second cylinder 14 applies a downward force F to the lower saddle 61, and the upper left second cylinder 14 applies an upward force F 'to the upper saddle 61, the force F being parallel to and opposite in direction to the force F'. Thus, the force F generates a tangential component F1 and a radial component F2, and the force F ' generates a tangential component F1 ' and a radial component F2 '; when the tangential component force F1 and the tangential component force F1' are large enough and overcome the friction force, the support 6 can drive the rotating plate 51 to generate tangential acceleration, so that the rotating plate 51 rotates around the center thereof, and the rotating plate 51 rotates clockwise by a certain angle, thereby achieving the purpose of adjusting the angle of the large-scale ball mill in the horizontal plane.

By providing a positioning groove 45, the position of the roller 46 is limited and it is ensured that the roller 46 can roll around its own vertical axis in this positioning groove 45. By arranging the rollers 46 in rolling fit with the circumferential surface of the rotating plate 51, when the rotating plate 51 rotates, the friction mode between the rotating plate 51 and the top plate 42 is changed, the friction force between the rotating plate 51 and the top plate 42 is reduced, and the abrasion between the rotating plate 51 and the top plate 42 is reduced. The rollers 46 may be cylindrical rollers, tapered rollers, spherical rollers, or the like.
To facilitate the mounting of the rollers 46, it is preferred that the top of the positioning slot 45 is provided with an opening, as shown in fig. 5, for mounting the rollers 46 into the positioning slot 45 from the top opening of the positioning slot 45.
