The lifting device comprises a multi-connecting-rod mechanism, the multi-connecting-rod mechanism comprises a first four-rod mechanism and a second four-rod mechanism which are connected with each other in the height direction, the lower end of the first four-rod mechanism is connected with a vehicle body, and the upper end of the second four-rod mechanism is connected with a rotating platform with an autorotation function; the power device is arranged on the mounting plate, connected with the first four-bar mechanism and used for driving the first four-bar mechanism to rotate; and the limiting device is vertically arranged on the vehicle body and is connected with the rotating platform. By arranging the power device, the crank is driven to swing upwards within a certain angle, then the power pull rod of the multi-connecting-rod mechanism is pulled to move leftwards, the included angle between the upper connecting rod and the lower connecting rod is increased, and the limiting device limits the upper rotating platform to move rightwards, so that the rotating platform has lifting motion; the device has the advantages of being compact in structure, high in stability, small in size, flexible in arrangement and the like, and has high cost performance and selectivity for the AGV.
本发明公开了一种举升装置及其搬运车辆,包括多连杆机构,其包括在高度方向相互连接的第一四杆机构和第二四杆机构,所述第一四杆机构下端与车体连接,所述第二四杆机构上端连接具有自转功能的旋转平台;动力装置,其设置在安装板上,并与第一四杆机构连接,用于驱动第一四杆机构转动;以及限位装置,其竖直的设置在车体上,并与旋转平台连接。本发明通过设置动力装置,驱动曲柄在一定角度内向上摆动,进而拉动多连杆机构的动力拉杆向左运动,使得上下连杆夹角增大,而限位装置限制了上部旋转平台向右运动,使得旋转平台具有升降运动,此装置具有结构紧凑、稳定性高和体积小、布置灵活等特点,对AGV小车具有较高的性价比和可选性。
