Detailed Description

The invention is described in detail below with reference to the following figures and specific embodiments:

as shown in fig. 1 and 2, the device for overturning a large-area flat workpiece comprises a fixed support frame 1, a lifting beam 2, a suspension rod 3 and two clamping sleeves 4, wherein the two clamping sleeves 4 are arranged to respectively clamp two ends of the workpiece 5, the two clamping sleeves 4 are connected with the lifting beam 2 through the suspension rod 3, when the lifting beam 2 falls onto the fixed support frame 1, the clamping sleeves 4 are manually rotated to realize horizontal overturning of the workpiece 5, the clamping sleeves 4 comprise a containing frame 41, a rotating shaft 42, radial thrust ball bearings 43, a gland nut 44, a bearing seat 45 and a bearing cover 46, the containing frame 41 is arranged to be a cage-shaped part capable of containing one end of the workpiece 5 in the width direction, the large end platform stage of the rotating shaft 42 is fixedly arranged at the central position of the end face of the containing frame 41, the middle platform stage is oppositely provided with the two radial thrust ball bearings 43, and the small end platform stage is screwed and locked through the gland nut 44, bearing seats 45 are arranged on the two radial thrust ball bearings 43, bearing covers 46 are fixed outside the bearing seats 45, and the suspension rods 3 are fixedly arranged on the bearing seats 45 and connected to the pin shafts 22 of the hoisting beams 2 through lifting lugs 31 at the tops.

As a preferable mode, in this embodiment, the hoisting cross beam 2 is provided with a plurality of reserved pin holes 21, and the pin 22 is adjusted according to the length of the workpiece 5 and inserted into a proper pin hole 21, so as to adapt to hoisting and turning over workpieces with different lengths.
