Abstract

The invention discloses an electro-hydraulic spiral servo drive shearing fork type heavy lifting platform which comprises a chassis, an electro-hydraulic spiral servo drive system, a working table, a shearing fork type structure, an upper guide rail and a lower guide rail. The shearing fork type heavy lifting platform is a plane single degree-of-freedom mechanism and is driven and controlled by the electro-hydraulic spiral servo drive system mounted on the chassis, so that center of gravity of the lifting platform is effectively lowered, and intelligent control is facilitated with introduction of the servo drive system; the electro-hydraulic spiral servo drive system is a four-lead-screw driving mechanism and is designed based on the overdrive method of intelligent control and the D'Alembert's principle, so that the problems about unbalance loading, unstability and synchronization caused by errors of processing and assembling of the shearing fork type heavy lifting platform are effectively solved, the stability and reliability are greatly improved, and the carrying capacity is effectively improved; the shearing fork type structure is high in reconfigurable capacity and structural strength; and the lifting platform is particularly suitable for occasions including digitization workshops, intelligent logistics warehouses and the like for vertically conveying heavy cargos.

Description

technical field

[0001] The invention relates to the field of scissor-type lifting platforms, in particular to an electro-hydraulic spiral servo-driven scissor-type heavy-duty lifting platform. Background technique

[0002] The scissor lift table is a kind of lifting equipment that can not only transport people vertically but also can carry out vertical transport in the material conveying system such as workshop or warehouse. According to the market demand, the working table of the scissor lift table can also be installed with various Class plane conveying equipment to meet the conveying requirements of different heights of the conveying line. Scissor lifts can generally be divided into fixed lifts and mobile lifts. Existing scissor lifts have been widely used in many fields, but many problems have been exposed during use. On the one hand, most of the existing scissor lifts use the hydraulic system as power, and the hydraulic cylinder installed on the scissor mechanism drive...
