The invention discloses a lifting platform for vehicle maintenance. The lifting platform comprises a base, a lifting plate and a driving assembly, the driving assembly drives the lifting plate to rotate along the hinge joint part of the lifting plate and the base, the driving assembly comprises a mounting base, a hydraulic cylinder, a connecting piece, a vibration sensor, a telescopic sleeve, a telescopic column, a locking ring, a sliding groove, a locking pin, a special-shaped locking groove, an annular electromagnet, a floating block, a locking block, a limiting groove, a kidney-shaped groove and an elastic piece. The lifting platform has the beneficial effects that a locking pin abuts against the interior of a horizontal section groove and then dispersedly supports the weight of a vehicle together with the hydraulic cylinder, the influence on the service life of the hydraulic cylinder is reduced, the phenomenon that hydraulic pressure is unstable due to abrasion of the hydraulic cylinder is reduced, and meanwhile, the buffering time for rapidly and safely evacuating maintenance workers from the position below the vehicle is given, and potential safety hazards are reduced.
本发明公开了一种车辆维修用升降台,包括底座、升降板、驱动组件驱动其沿与底座的铰接处转动,驱动组件包括安装座、液压缸、连接件、震动传感器、伸缩套、伸缩柱、锁止环、滑动槽、锁止销、异型锁止槽、环形电磁铁、浮动块、锁止块、限位槽、腰形槽、弹性件。本发明所达到的有益效果是:锁止销抵紧在水平段槽内,进而与液压缸一起对车辆的重量进行分散支撑,降低对液压缸的使用寿命影响,减少了由于液压缸磨损而产生的液压力不稳的现象,同时给与维修工人快速从车辆下方安全撤离的缓冲时间,减少安全隐患。
