The invention provides a vehicle-mounted lifting device which is used for being mounted on a disassembly and assembly repair vehicle and belongs to the technical field of maintenance safeguard. The disassembly and assembly repair vehicle is provided with a lifting mechanism and a supporting unit, wherein the supporting unit is used for supporting the disassembly and assembly repair vehicle during lifting, and the supporting unit comprises a cross arm, a first driving piece, a second driving piece and a supporting block; during use, the cross arm is unfolded outwards from the disassembly and assembly repair vehicle, the first driving piece is driven by the second driving piece to move downwards; and when the cross arm moves to a certain position, the first driving piece is opened, so that the driving end of the first driving piece drives the supporting block to be supported on the ground. On a relatively steep section, the second driving piece drives the first driving piece to move downwards, so that the supporting height from the cross arm to the ground can be increased, the supporting block can be stably supported on the ground, the operation of manually leveling the ground is reduced, manpower and material resources are saved, and the hoisting efficiency can be effectively improved.

    本发明提供了一种随车起吊装置,用于安装在拆装修理车上,属于维修保障技术领域,通过在拆装修理车上设置有吊装机构和支撑单元,支撑单元用于在吊装时对拆装修理车进行支撑,支撑单元包括横臂、第一驱动件、第二驱动件和支撑块,在使用时,通过将横臂从拆装修理车上向外展开,并通过第二驱动件驱动第一驱动件向下运动,在运动到一定位置时,打开第一驱动件,使第一驱动件的驱动端带动支撑块支撑在地面上,本发明在遇到较陡地段时,通过第二驱动件驱动第一驱动件向下运动能够增加横臂到地面的支撑高度,使支撑块能够稳固的支撑在地面上,减少人工垫平地面的操作,节省人力物力,可以有效提高吊装的效率。
