The utility model discloses a balanced lifting by crane ware is generally applied to because the rings mounted position who lifts by crane the thing is injectd, can only lift by crane the screw hole in two positive processing, and the focus that lifts by crane the thing moreover is not with two rings line coincidences that lift by crane for the foundry goods produces the slope phenomenon when lifting by crane. The periphery of a small and medium-sized rotating wedge casting 13 similar to an automobile mould is higher in guiding precision with a base body casting, the inclination of the casting can cause that a fitter is difficult to put in, install, detach and lift out, and the method can be completed by manually holding a steel bar to perform multi-point knocking at multiple positions, lifting for multiple times at a sectional distance and the like. The utility model discloses a balanced lifting device generally adopts two symmetries to use.

The working principle is as follows:

firstly, a screw rod 8 at the lower part of a lifting rod 1 of two balance lifting devices penetrates through a circular base plate 4 and is screwed into a lifting threaded hole of a rotary wedge casting 13 by a fitter, a lock catch 14 is installed at an upper lifting hole 10 at the upper end of the lifting rod 1, two steel ropes 16 in four steel ropes 16 with equal length on the crane are respectively sleeved into the two lock catches 14, the crane is started firstly, the steel ropes 16 moving upwards by a lifting hook are tensioned and stop after lifting the casting, the casting is judged to incline, then the casting is placed on the ground, simultaneously, the steel ropes 16 are kept in a tensioned state, at the moment, the fitter installs a lifting vertical plate 2 and a locking block 3 in a rectangular through groove 7 of the lifting rod 1, a hanging part faces to the incline direction, namely the gravity center direction, a fastening screw 5 penetrates through a through hole of a protruding plate 15 to tighten the locking block 3, so that the inclined planes 9 of the lifting vertical plate 2 and the locking block 3 are meshed and locked, and the end faces of a flange plate 11 and the locking block 3 clamp the end face of the rectangular through groove 7 of the lifting rod 1, and finishing the shape installation of the balance lifting device.

Then, the other two unused steel ropes 16 are pulled by a fitter by hands respectively, the flat lifting holes 12 in the lifting vertical plate 2 of the balance lifter are measured and calculated to judge which flat lifting hole 12 accords with the tensioning distance of the steel ropes 16, and then the lifting lock 14 is installed at one hole outside the consistent distance flat lifting hole 12. The bench worker operates the crane, lowers the lock catch 14 of the lifting hook on the lifting vertical plate 2, installs the steel rope 16, and thus the lifting lock catch 14 of the lifting vertical plate 2 is firstly stressed by lifting, the lock catch 14 on the lifting rod 1 plays an auxiliary role, and the casting is lifted to be flat. If the offset of the gravity center of the casting is large, the punching position of the lifting lock catch 14 of the lifting vertical plate 2 can be continuously adjusted until the casting is lifted flat.

The utility model relates to a balance lifting device, which is mainly used for the balance lifting of small and medium-sized rotating wedge castings 13 similar to automobile molds, namely for the conditions that the center of gravity is not at the center, the lifting position is deviated and the like; the utility model discloses a balanced lifting device and the threaded rod 8 screw thread fixed connection that lifts by crane the thing through 1 bottom of jib lift by crane, lift by crane through last lifting eye 10 earlier, then through the balance that the thing was lifted by crane of flat lifting eye 12 adjustment, it is more convenient to make the balance of rotatory slide wedge foundry goods 13 lift by crane, can revise the balanced angle that the foundry goods lifted by crane fast, has improved the assembly efficiency of pincers worker, has reduced workman's the operation degree of difficulty.

Of course, the present invention may have other embodiments, and those skilled in the art may make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
