The invention belongs to the technical field of machine manufacturing. In order to solve the technical problem in the prior art, the invention provides a manual and electric dual-control lifting device. The manual and electric dual-control lifting device comprises an electric push rod, the electric push rod adopts a worm and gear transmission form, and a worm is fixedly connected with a motor gear. The manual and electric dual-control lifting device is characterized in that one end of the worm extends out of a shell of the electric push rod and is provided with a hand-cranking device. The beneficial effects are as follows: when the electric push rod is electrically driven, the electric push rod drives a turbine and the worm to move through the rotation of the motor so as to realize the lifting of the electric push rod. When no electricity is available, the movement of the pair of the turbine and worm can also be realized by applying force to the shaft extension end of a gear shaft, sothat the lifting of the electric push rod in a non-electricity state is realized. Force application points can be flexibly set by additionally arranging a transmission flexible shaft, and force application difficulty caused by limitation of the installation position of the push rod is overcome.
本发明属于机械制造技术领域。为解决现有技术中存在的技术问题,本发明提供一种手电两控的升降装置,其包括电动推杆,所述电动推杆采用蜗轮蜗杆传动形式,所述的蜗杆与电机齿轮连接固定,其特征在于:所述蜗杆的一端伸出电动推杆的壳体,并在该端设有手摇装置。本发明的有益效果为:当电动推杆采用电驱动时,电动推杆通过电机的转动带动涡轮、蜗杆运动实现电动推杆的升降。当无电时,通过对齿轮轴轴伸端的施力同样可以实现涡轮、蜗杆对的运动,从而实现了无电状态下电动推杆的升降。通过增加传动软轴能够灵活设置施力点,客服由于推杆安装位置的局限性造成的施力困难。
