Description

Technical Field

[0001] The utility model relates to a double-push rod driving device. Background Art

[0002] The "double push rod" (hereinafter referred to as double push rod) method is a very common drive scheme in the servo system design of the vertical lifting or flipping mechanism of the working platform of medium and large equipment. At present, it is mainly divided into two drive forms: hydraulic push rod and electric push rod.

[0003] At present, in most application scenarios of double-screw rods, hydraulic control is mostly adopted. They all have a common problem: difficult maintenance, large system and insufficient flexibility.

[0004] Electric servo systems have become the recognized mainstream trend in servo system design and construction in recent years due to their simple structure, compact size, clean and pollution-free, long-term service and maintenance-free.

[0005] The dual-push-rod drive solution can effectively distribute large weight and spatially distributed loads to multiple push-rod actuators, which brings better versatility and convenience to the design, layout and engineering selection of the entire servo system. However, this drive method also brings about the frequent "stuck" problem of the dual push-rods: that is, for the dual-push-rod control system, we mostly implement it in a "precise synchronization" way, using two sets of completely symmetrical push-rod mechanisms, symmetrical electrical and geometric parameter design, processing and manufacturing until installation and commissioning. However, since "there are no two completely symmetrical things in the world", there are deviations in the actual symmetrical design, manufacturing and assembly. Coupled with factors such as deformation that gradually occurs over time, such a system will eventually have serious deviations in the dual push-rod motor load, resulting in motor overload, abnormal mechanical wear, noise, and other annoying faults.
