Abstract

The utility model discloses a hoisting machine balancing device for a hoisting device. A hoisting machine rotary disk (11) thereof is mounted at the upper middle part of a hoisting big frame (1), and a support base (6) is mounted at the upper middle part thereof; the upper end of the support base (6) is movably connected with a telescopic arm (7); a pillar (9) is arranged at the upper left end of the hoisting rotary disk (11), and movably connected with the telescopic arm (7); a pulley (8) is mounted at the upper end of the lifting shaft of the telescopic arm (7); support leg retracting mechanisms are movable mounted at four corners of the hoisting big frame (1); and a counterweight mechanism is arranged at the upper right end of the hoisting rotary disk (11). Because the utility model adopts the principle that an oblique line is larger than a vertical line, four crossed telescopic support legs and a movable control moving counterweight are designed, so that the grounding support area of the hoisting machine is increased, and the mobile counterweight can be properly adjusted according to the weight of an object hoisted, thereby effectively improving the stability of the hosting machine, increasing the weight of the object hoisted, improving work efficiency, and ensuring hoisting quality. Furthermore, the utility model has the advantages of convenient operation and strong usability.

Description

The loop wheel machine balancing device

Technical field:

The utility model relates to the loop wheel machine balancing device that a kind of hanging device uses.

Background technology:

Along with rapid economy development, the hanging device of building industry and carrying trade also obtains rapid progress.But now lift the loop wheel machine that goods uses, mostly the supporting leg deformation area is less, less stable during the lifting goods; Balance weight is fixed, and the lifting weight range is difficult for change, has influenced result of use.

The utility model content: the utility model provides a kind of ground connection Area of bearing to increase, and improves the stability of loop wheel machine, the loop wheel machine balancing device of significantly increasing work efficiency.Its loop wheel machine rotating disk 11 devices are the middle part on big 1 of loop wheel machine, middle part device seat 6 on it, bearing 6 upper ends and telescopic boom 7 flexibly connect, pillar 9 is arranged on left end on the loop wheel machine rotating disk 11, and and telescopic boom 7 flexibly connects, pulley 8 devices are in the upper end of the lifting shaft of telescopic boom 7, and supporting leg jack head is at big 1 four jiaos of ends of loop wheel machine, and balance weight mechanism is arranged on right-hand member on the loop wheel machine rotating disk 11.Because the utility model adopts the principle of oblique line greater than vertical line, intersection four-way telescopic outrigger and movable control mobile counterweight have been designed, loop wheel machine ground connection Area of bearing is increased, can suitably regulate mobile counterweight according to the weight of hanging object, effectively improve the stability of loop wheel machine, increase the weight of lift cargo, improved work efficiency, guaranteed the lifting quality, and easy and simple to handle, practical.

Description of drawings:

Fig. 1 is the new front view of this practicality

Fig. 2 is the birds-eye view of Fig. 1

The specific embodiment;

As shown in Figure 1 and Figure 2, loop wheel machine rotating disk 11 device is the middle part on big 1 of loop wheel machine, it in the middle part of device seat 6, bearing 6 upper ends and telescopic boom 7 flexibly connect, pillar 9 is arranged on left end on the loop wheel machine rotating disk 11, and flexibly connects with telescopic boom 7, and pulley 8 devices are in the upper end of the lifting shaft of telescopic boom 7.Supporting leg jack head is at big 1 four jiaos of ends of loop wheel machine, and balance weight mechanism is arranged on right-hand member on the loop wheel machine rotating disk 11.

As shown in Figure 1 and Figure 2, the supporting leg jack is movably arranged on lower end in the supporting leg 2 by four legs 3, and horizontal end intersects head up and down at big 1 four jiaos of ends of loop wheel machine on the supporting leg 2.Mainly be the activity of the intersection up and down extraction that utilizes supporting leg, loop wheel machine ground connection Area of bearing is increased, effectively improved the stability of loop wheel machine.

As shown in Figure 1 and Figure 2, balance weight mechanism is arranged on right-hand member on the loop wheel machine rotating disk 11 by moving counterweight seat 5, and it is right inner that clump weight 11 is arranged on moving counterweight seat 5, and electronics weighing scale 1 is arranged on left end on the loop wheel machine rotating disk 11.Mainly be to utilize suitably to regulate mobile counterweight and electronics check weighing, increased the weight of lift cargo, improved work efficiency, guaranteed the lifting quality.
