The straight arm type aerial work platform with the height capable of being finely adjusted comprises a vehicle body, a combined arm frame structure and a work table structure, and the work table structure comprises an L-shaped frame, an outer frame body, a fixing plate, a platform assembly, a transmission assembly and a guide assembly. The working table is of a double-layer structure, namely the outer frame body and the working platform assembly, the transmission assembly is further arranged in the outer frame body, the main rotating shaft is driven to rotate through the rotating oil cylinder of the transmission assembly, and then the two secondary rotating shafts are driven to rotate through the meshing effect of the worm gear and the worm; then four lead screws in four telescopic main rods are driven to rotate through the meshing effect of driving bevel gears and driven bevel gears, then the height of telescopic auxiliary rods is adjusted, the effect of fine adjustment of the height of the platform assembly is achieved, and the four telescopic auxiliary rods apply force to the four corners of the platform assembly at the same time and are matched with a guide assembly; therefore, when the height needs to be adjusted frequently for operation, the vertical movement can be realized, the shaking amplitude is small, and operators are safer.
本发明公开了一种可微调高度的直臂式高空作业平台,包括车体、组合式臂架结构及作业台结构,所述作业台结构包括L型架、外框体、固定板、平台组件、传动组件及导向组件。本发明作业台结构中为双层结构,即外框体和作平台组件,在外框体内还设置了传动组件,通过传动组件的旋转油缸带动主转轴转动,进而通过蜗轮蜗杆啮合作用带动两个次转轴转动,再通过主动锥齿轮和从动锥齿轮的啮合作用带动四个伸缩主杆内的四个丝杆转动,进而调节伸缩从杆的高度,达到平台组件高度微调的效果,且通过四个伸缩从杆同时对平台组件四角位置同时施力,再配合导向组件,使得高度微调时更加平稳,如此一来在需要频繁调节高度进行作业时,更加方便,可以实现垂直移动,晃动幅度也小,使得作业人员更安全。
