A lifting device for building construction

Abstract

The invention discloses lifting equipment for building construction. The lifting equipment comprises a base; a movable type wire winding device is arranged on one side of the upper end of the base; alifting device is arrange on the other side of the base; the movable type wire winding device is composed of guide rails, guide grooves, triangular-prism-shaped supporting frames, a screw rod, a frequency-modulation motor, a connecting frame, semicircular-arc-shaped grooves, sliding grooves, disc-shaped movable supporting bases, sliding supporting rods, first telescopic air cylinders, a rotating shaft, a wire winding cylinder and a first rotating motor; the lifting device is composed of a vertical supporting frame, an auxiliary wire winding device, a supporting plate, a supporting arm, a lifting air cylinder, a main lifting arm, a first inclined air cylinder, a long groove, a secondary lifting arm and a second telescopic air cylinder; and the auxiliary wire winding device is composed of amain rolling wheel, a second rotating motor, arc-shaped guide rails, arc-shaped guide grooves, sliding bases, secondary rolling wheels, a fixing base, telescopic connecting rods and second inclined air cylinders. The lifting equipment has the advantages of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of construction, in particular to a lifting device used for construction. Background technique [0002] It is often necessary to carry some larger and heavier items on the construction site. If it is carried manually, it is not only inefficient, but also life-threatening. It is often seen on the construction site that the items are lifted by controlling the retraction and release of the rope. Equipment, in this equipment, the motor controls the reel to realize the retraction and release of the rope. When the objects to be lifted by the rope are too heavy, it is easy to cause the motor overload phenomenon, thereby reducing the service life of the motor; the reel drives the rope The retraction and release of the rope is different, and the cut angle between the stress-bearing end of the rope and the outer end of the reel will also change the retraction and release force of the rope; the existing building hoisting equipme...

[0002] It is often necessary to carry some larger and heavier items on the construction site. If it is carried manually, it is not only inefficient, but also life-threatening. It is often seen on the construction site that the items are lifted by controlling the retraction and release of the rope. Equipment, in this equipment, the motor controls the reel to realize the retraction and release of the rope. When the objects to be lifted by the rope are too heavy, it is easy to cause the motor overload phenomenon, thereby reducing the service life of the motor; the reel drives the rope The retraction and release of the rope is different, and the cutting angle between the stress-bearing end of the rope and the outer end of the reel will also change the retraction and release force of the rope; the existing building hoisting equipment has a single function and can achieve less movement, so Now there is a need for a lifting device for building construction. This device can realize various adjustment movements such as up and down and horizontal. The auxiliary winding device provided can relieve the pressure of the winding drum motor to a certain extent, thereby increasing its service life. , the equipped mobile reel winding device controls the cut angle between the reel and the rope by changing the horizontal position and height position of the reel, and changes the retracting force of the rope
