Abstract

The invention discloses a shear-fork type lifting platform with wheel train transmission. The shear-fork type lifting platform comprises a base, wherein a driving unit and two parallel shear-fork type units are arranged on the base, and the lower ends of the two shear-fork type units are fixedly connected with two parallel driving rods; the driving rods are rotationally connected with a lower connecting piece fixed on the base, and the upper ends of the shear-fork type units are rotationally connected with the lower surface of a working platform; the driving unit is connected with the two driving rods and used for driving the driving rods to synchronously relatively rotate. According to the shear-fork type lifting platform, under the driving of a driving motor, a driving wheel and a driven wheel keep synchronous relative rotation, the driving rods are driven to rotate, the lifting motion of the shear-fork type unit is realized, and therefore the lifting motion of the working platform is realized. The working stroke is greatly increased, and the unnecessary space is reduced. Meanwhile, the torque is increased, and the working load of the working platform is improved.

Description

technical field [0001] The invention belongs to the technical field of scissor lift platforms, and in particular relates to a scissor lift platform driven by a wheel train. Background technique [0002] With the construction and development of high-altitude installation, maintenance and other operations, the lifting platform has been widely used as a commonly used high-altitude operation equipment. The lifting platform can be divided into five categories according to its structure: aluminum alloy lifting platform, cylinder type lifting platform, scissor lifting platform, crank arm lifting platform and guide rail chain lifting platform. Among them, the lifting platform using the scissor lifting mechanism has the characteristics of large expandable ratio, compact structure, large carrying capacity, strong passability and good maneuverability, so it is widely used in different working environments. [0003] The scissor lift mechanism is a folding mechanism, which includes two ...
