Abstract

The invention relates to a spiral lifting device for building construction, which includes a workbench, a column, a lower base plate, and a secondary transmission device. It includes a motor, a large gear, a small gear, a base, a shaft, a transmission rod, an externally threaded rod, and an internally threaded rod. The motor is arranged on the upper part of the lower bottom plate and connected by bolts. The large gear and the motor are connected by a large flat key. The base is arranged on the top of the lower bottom plate and Connected by bolts, the shaft is set in the inner hole of the pinion and connected by a flat key, the pinion is set on the upper end of the base and connected by a bearing, the transmission rod is set at the lower end of the internal threaded rod and connected by bolts, and the external threaded rod is set The periphery of the internal threaded rod is connected by threads. The invention has the advantages of reasonable structure, convenient use, good stability, high precision of start-stop control, no skewing, large bearing capacity and long service life.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a spiral lifting device for building construction. Background technique [0002] The screw jack is composed of worm gear, box, bearing, screw and other components. The working principle is: the motor or manual drives the worm to rotate, the worm drives the worm gear to decelerate and rotate, the inner cavity of the worm gear is processed into an internal thread, and the driving screw moves up and down to achieve the effect of lifting. The screw jack is mainly used in the adjustment structure of mechanical lifting action, and is widely used in the field of construction. However, the start-stop control accuracy of the existing screw jack is not ideal. When the construction object to be lifted is heavy and bulky, the screw jack will be inclined, which is easy to cause damage to the screw rod. Contents of the invention [0003] The technical problem to be solved by the presen...
