The cantilever beam mechanism includes a cantilever beam, an electric hoist, an operating rod and a rotating module, the cantilever beam is arranged on the rotating module, an operating rod is arranged on the rotating module, and the electric hoist is arranged at the lower part of the cantilever beam.

The rotary module includes a slewing support bearing, a rotating rod and a thrust bearing. The slewing support bearing is arranged on a base, and the lower part of the slewing support bearing is connected to the thrust bearing through a rotating rod.

A counterweight is arranged at the end of the operating rod.

The base is a square tube cube frame structure.

The utility model adopts a square tube cube frame structure as the base, and bolt holes are arranged on the peripheral side of the bottom, so that it can set a support rod on it, thereby increasing the stability of the base, so that it can lift heavy objects according to the quality , Angle, height and other factors are comprehensively analyzed to obtain the best lifting effect; the slewing ring bearing is set on the base, and the slewing ring bearing is connected with the thrust bearing set in the base through the rotating rod, so that the thrust bearing can lift It has a very good stabilizing effect; and because of the use of the slewing ring bearing, it can not only bear the radial force but also the axial force; the cantilever beam is set on the upper part of the slewing ring bearing, so that the electric hoist can lift the weight through the pulley set on its upper end. Objects, the electric hoist is set on the rotating module so that it can reduce the counterweight of the cantilever beam, and the operating rod is connected to the rear of it, so that it can control the rotation angle of the heavy object and also play a role in balance; it can also be used in The counterweight is set at the rear so that it can balance the gravity of the heavy object, and the electric hoist is used to make it lift and fall very labor-savingly, and the utility model sets threaded holes at the bottom so that it can not only connect the support rod but also can Connect mobile machinery to make the base more stable.

In the utility model, a threaded hole is provided at the lower part of the base so that it can be provided with a support rod, and it can also be provided on a mobile mechanical device; a rotating module is provided on the base and a lifting mechanism such as a cantilever beam is provided on it, and the cantilever beam The large angle with the horizontal plane enables it to obtain the maximum lifting height and the minimum space occupation; after adopting this device, it can work in the narrowest space, which fills the lack of laborious lifting in small spaces, and is worthy of application and promotion.
