The pneumatic pump is respectively connected with the first cylinder 1, the second cylinder 2, the third cylinder 6 and the fourth cylinder 7.

The detailed working principle is as follows:

this scheme is through setting up the mounting bracket in two-layer, when hoisting the mounting bracket, first shelf layer 12 can be in earlier and suspend the state in midair, second shelf layer 13 has not yet been hoisted this moment, even first shelf layer 12 unbalanced force produces and rocks and also can not influence the second floor, when second shelf layer 13 suspends in midair gradually, first shelf layer 12 also tends towards steadily gradually, thereby the effect of buffering has been reached, make the second floor can not rock too big margin, and can be faster tend towards the balance, and then make the handling process more steady.

In the process that the second frame layer 13 is hoisted, the first cylinder 1 and the second cylinder 2 respectively drive the first piston rod 3 and the second piston rod 4 to stretch and retract towards the opposite side to drive the clamping piece 5 to clamp or loosen the plate. When first piston rod 3 and second piston rod 4 inwards shrink, drive the driving plate inward movement of both sides, thereby make laminating subassembly 10 support the solid with panel from the both sides of panel, laminating subassembly 10 laminates with the upper surface and two lateral walls of panel respectively completely this moment, press from both sides tight panel from both sides, make panel can not produce the displacement because of rocking at the hoisting in-process, because the symmetry of its structure, the focus is stable, as long as panel does not appear the displacement when starting, even take place the short time and rock and also can resume steadily by oneself, and can not lead to the focus to change because of the displacement, and then make follow-up handling stable balance. In the process, because the distance between the attaching assemblies 10 at the two ends and the first cylinder 1 and the second cylinder 2 is larger, the pressure of the joint of the first piston rod 3 and the first cylinder 1 is increased under the influence of gravity (the same applies to the second piston rod 4), namely, the two ends hang downwards relative to the middle position, so that the relative sliding of the two ends is hindered, and at the moment, the pulley 11 can play a role of a certain balance weight, so that the influence is reduced; simultaneously, pulley 11 can also play the supporting role, makes the junction of first piston rod 3 and first cylinder 1 can not take place to deform because of the pressure of both ends laminating subassembly 10, reduces this hindrance, and pulley 11 is when supporting, and first piston rod 3 and second piston rod 4 still can stretch out, nevertheless because pulley 11 is smooth relatively, slide more smoothly, and can not cause the scratch to the panel surface.

When the first piston rod 3 and the second piston rod 4 inwards contract to clamp the plate, the first ejector rod 8 and the second ejector rod 9 can be stretched to prop against the limiting block 15 to enable the limiting block 15 to be subjected to resistance and not to move any more, so that the contraction of the first piston rod 3 and the second piston rod 4 is blocked, the pressure of the plate subjected to the laminating assembly 10 is reduced, and the plate is prevented from being damaged due to overlarge pressure.

The second embodiment:

the second embodiment is different from the first embodiment only in that the clamping member does not include a fitting component, the specific shape and structure are shown in fig. 2 and 3, fig. 2 corresponds to the lower left corner of fig. 1, and fig. 3 corresponds to the lower right corner of fig. 1; the lower end of the clamping piece is provided with a hook part, and the vertical height difference between the bottom of the pulley and the upper surface of the hook part is slightly larger than the thickness of the plate; when clamping, the upper surface of hook portion and the lower surface contact of panel, the upper surface contact of pulley and panel this moment, and the pulley almost has no pressure to panel upper surface this moment, can not harm the panel. This scheme is compared more stable when embodiment a handling, even certain sucking disc damages to lead to the absorption of panel upper surface to go wrong, also can make panel transportation steadily through the support to the solid and to the support power of panel bottom surface of supporting to panel side, can not take place to rock and the displacement.
