Detailed Description

The invention is further explained with reference to the drawings.

A150 TON multipurpose lifting bar is shown in figure 1 and comprises a circular tube 1 which is transversely placed, the diameter of the circular tube is 508mm, lifting lug plate groups are symmetrically welded on the left side and the right side of the circular tube, and each lifting lug plate group is provided with a first lifting lug plate and a second lifting lug plate.

The first lifting lug plate is provided with a first upper lifting lug plate and a first lower lifting lug plate, the first upper lifting lug plate and the first lower lifting lug plate are symmetrically welded on two sides of the circular tube, a first upper lifting lug is welded on the first upper lifting lug, a first lower lifting lug is welded on the first lower lifting lug plate, and a connecting line of the first upper lifting lug and the first lower lifting lug and the central axis of the circular tube form a 77-degree included angle. The second lug plate is provided with a second upper lug plate and a second lower lug plate, the second upper lug plate and the second lower lug plate are symmetrically welded on two sides of the circular tube, the second upper lug plate is welded with four second upper lugs, the second lower lug plate is welded with four second lower lugs, and the four second upper lugs and the four second lower lugs are in one-to-one correspondence. The distance between every two adjacent second upper lifting lugs is reduced from outside to inside in sequence; and the distance between the adjacent second lower lifting lugs is reduced from outside to inside in sequence. The connecting line of the second upper lifting lug and the corresponding second lower lifting lug forms an included angle of 77 degrees with the central axis of the circular tube. Through structural strength analysis, the 77-degree included angle structure is an optimal structure, the problems that the operation span needs to be lifted in a double-lifting combined mode and the use angle of the lifting lug is limited in the lifting process are solved, and higher guarantee is obtained on operation safety.

The first upper lifting lug and the second upper lifting lug are connected with the crane hook head through the shackle and the steel wire rope, the first lower lifting lug and the second lower lifting lug are connected with the hoisted segment or equipment through the shackle and the steel wire rope, and meanwhile, the included angle of the steel wire rope of the crane hook head is ensured to be smaller than 60 degrees. At the tip of first lug plate, second lug plate, and first lug, the lug department of going up of second, the outer surface welding of pipe has the ring, and the ring plays limiting displacement to the shackle at the operation in-process. As shown in fig. 2, a lifting lug main plate 9 is connected between the first upper lifting lug and the first lower lifting lug, and the lifting lug main plate is inserted into the circular tube and welded and fixed; and a lifting lug mainboard is connected between the second upper lifting lug and the corresponding second lower lifting lug, and the lifting lug mainboard is inserted into the inner part of the circular tube and is welded and fixed.

150TON multipurpose lifting lever divide 5 bilateral symmetry altogether and pair the use operating mode, and upper and lower lug pairs the use during the use, guarantees bilateral symmetry level simultaneously and uses to prevent hoist and mount off-centre and atress inequality. 85 tons of shackle and steel wire ropes not less than 85 tons are prepared before the hanging bar is installed, the steel wire ropes need to be connected and fixed in sequence, and a plurality of tools cannot be connected simultaneously. When in hoisting, the hoisting needs to be slowly carried out, standing personnel are forbidden around, and formal hoisting operation can be started after the section or the equipment is stably hoisted away from 100-200 mm.
