A transport vehicle of an unmanned transport system comprises a base structure and a load bearing device which is arranged above the base structure, is supported by an electro-hydraulic lifting device (15) and is adjustable in height. The lifting device (15) comprises a hydraulic unit (16) capable of achieving reverse conveying and at least three hydraulic lifting cylinders (19), and the hydraulic lifting cylinders (19) are connected to the hydraulic unit through connecting pipelines. The hydraulic lifting cylinders (19) are parallel to each other and are configured as differential cylinders. The hydraulic lifting cylinders (19) are dimensioned in a stepped manner such that the rod chamber (26.n) of the nth lifting cylinder (19. N) and the rodless chamber (27.n + 1) of the (n + 1) th lifting cylinder (19. N + 1) have the same effective area, where n is 1 to z-1, and z represents the number of hydraulic lifting cylinders (19) of the lifting device (15). The at least three lifting cylinders (19.1, 19.2, 19.3, 19.4) are hydraulically connected in series such that individual chambers (26.1, 27.2, 26.2, 27.3, 26.3, 27.4) having the same active area are directly fluidically coupled via hydraulic connection points (28a, 28b, 28c). The rodless chamber (27.1) of the first lifting cylinder and the rod chamber (26.z) of the z-th lifting cylinder are in liquid connection with the connection points (29, 30) of the hydraulic unit (16) which can be conveyed in the reverse direction.

    一种无人驾驶运输系统的运输车辆,包括基座结构和承载装置,该承载装置设置在基座结构上方,受电动液压起升装置(15)支撑并可调节高度。所述起升装置(15)包括可逆向输送的液压单元(16)和至少三个液压起升缸(19),所述液压起升缸(19)通过连接管道连接到所述液压单元。所述液压起升缸(19)彼此平行并被配置为差动缸。液压起升缸(19)的尺寸是阶梯式的,使得第n起升缸(19.n)的有杆腔(26.n)和第n+1起升缸(19.n+1)的无杆腔(27.n+l)具有相同的有效面积,其中n为1到z-1,z表示起升装置(15)的液压起升缸(19)的数量。所述至少三个起升缸(19.1、19.2、19.3、19.4)通过液压串联连接,使得具有相同有效面积的各个腔(26.1、27.2、26.2、27.3、26.3、27.4)通过液压连接点(28a、28b、28c)进行直接液体耦合。第一起升缸的无杆腔(27.1)和第z起升缸的有杆腔(26.z)与可逆向输送的液压单元(16)的连接点(29、30)呈液体连接。
