As shown in fig. 2 and 5, the traverse cylinder 8 is located at the head of the arm support, two ends of a piston rod of the traverse cylinder are connected with the knuckle bearings of the arm support 1 and the arm support 2, an annular hoop thread column 15 is arranged on a cylinder body of the traverse cylinder 8, and a square nut 16 matched with the annular hoop thread column 15 is arranged on the annular hoop thread column 15.

As shown in fig. 2 and 7, one end of the connecting frame 9 is provided with a square groove 17, the connecting frame 9 is clamped on a square nut 16 on the cylinder body of the traversing cylinder 8 through the square groove 17, and the other end of the connecting frame 9 is fixed on the main shaft 3.

As shown in fig. 2, the first and

second cover plates

71, 72 are fixedly connected to the platform girder 18 and move together with the conveying platform.

As shown in fig. 2, the first rolling bracket 51, the second rolling bracket 52, the third rolling bracket 53, and the fourth rolling bracket 54 are fastened to the platform girder 18 by bolts 20.

The platform attitude adjusting mechanism mainly realizes two actions, namely a rolling action and a transverse moving action, and has the working principle that: and (3) rolling action: the roll motion refers to rotation about an axis in a vertical plane with reference to the horizontal plane to achieve a degree of deflection of the platform relative to the horizontal plane. See fig. 8 below, which is a roll motion.

As shown in fig. 2-3, when the conveying platform reaches a specified height, the arm support 1 and the arm support 2 stop moving, at this time, the main shaft 3 and the conveying platform are in a horizontal state, and the first roll cylinder 41, the second roll cylinder 42, the third roll cylinder 43 and the fourth roll cylinder 44 are all in the same horizontal state. The first rolling cylinder 41 and the second rolling cylinder 42 are controlled to enable piston rods of the first rolling support 51 and the second rolling support 52 to extend slowly, under the assistance of the joint bearing 14, the first rolling support 51 and the second rolling support 52 are driven to move to the upper right along with the friction rolling of the cover plate 71 fixedly connected with the girder 18 along the roller 11, meanwhile, the rolling cylinder 43 and the rolling cylinder 44 are controlled to enable the piston rods of the rolling cylinders to retract slowly, the third rolling support 53 and the fourth rolling support 54 are driven to move to the lower left along with the friction rolling of the cover plate 72 fixedly connected with the girder 18 along the lower left along the roller 11, and therefore the integral lower right deflection of the conveying platform is achieved. Similarly, the third and

fourth roll cylinders

43 and 44 are controlled to fully extend the piston rods thereof, and the first and

second roll cylinders

41 and 42 are controlled to fully retract the piston rods thereof, so that the integral left-down deflection of the conveying platform can be realized, that is, all roll motions of the conveying platform are realized;

transverse moving action: it is meant that the transport platform is moved side-to-side along a horizontal plane.

When the conveying platform reaches a specified height, the arm support 1 and the arm support 2 stop moving, at the moment, the main shaft 3 and the conveying platform are in a horizontal state, and the roll oil cylinder 41, the roll oil cylinder 42, the roll oil cylinder 43 and the roll oil cylinder 44 are all in a locking state.
