The invention relates to the technical field of transfer trolleys, and provides a transfer trolley. The transfer trolley comprises a scissor fork lifting mechanism comprising a lower chassis, an upper tray, scissor fork rod sets and a hydraulic driving device, wherein the scissor fork rod sets are arranged between the lower chassis and the upper tray; the fixed end of the hydraulic driving device is connected to the lower chassis, and the telescopic end of the hydraulic driving device is connected to the scissor fork rod sets and used for enabling the upper tray to do lifting motion. a bearing platform is arranged on the upper tray and is suitable for bearing a switch cabinet; and automatic locking mechanisms comprise locking pins, are telescopically arranged at the joints of the scissor fork rod sets and the upper tray, and have an unlocking state for allowing the scissor fork rod sets to move in the first direction and a locking state for limiting the scissor fork rod sets to move in the second direction opposite to the first direction. According to the transfer trolley, lifting of the bearing platform is achieved through the scissor fork lifting mechanism, use is more convenient, and time and labor are saved. Moreover, the automatic locking mechanisms can lock the scissor fork rod sets after height adjustment is completed, so that the bearing platform is prevented from falling back.

    本发明涉及转运车技术领域,提供一种转运车,包括:剪叉式升降机构,包括下底盘、上托盘、剪叉杆组以及液压驱动装置;剪叉杆组设置在下底盘和上托盘之间;液压驱动装置的固定端与下底盘连接,液压驱动装置的伸缩端与剪叉杆组连接,用于使上托盘做升降运动;承载平台,设置在上托盘上,适于承载开关柜;自动锁定机构,包括锁定销,可伸缩地设置在剪叉杆组与上托盘的连接处,具有允许剪叉杆组沿第一方向运动的解锁状态,以及限制剪叉杆组沿与第一方向相反的第二方向运动的锁紧状态。该转运车,利用剪叉式升降机构来实现承载平台的升降,使用更加便捷,省时省力。而且,自动锁定机构,可以在完成调高后对剪叉杆组进行锁紧,防止承载平台回落。
