The invention discloses a vehicle-mounted vertical lifting type operation platform vehicle which comprises a motor vehicle, an operation platform, a main cylinder, a first lifting cylinder, a second lifting cylinder, a motor, a lifting screw, an electric hoist and a lifting control device. The lifting control device comprises a first nut, a second nut, a ball disc, a double-end universal ball, a pulling plate, a spring, a tubular regular polygon column and a ball disc connecting pipe, the double-end universal ball is installed in a double-end universal ball sliding way and can slide in the radial direction, so that the outer ball enters or retreats from the outer ball groove, the inner ball enters or retreats from the inner ball groove, and the outer ball and the inner ball are connected through the pulling plate. A lifting screw is driven by a motor to rotate, and a first nut and a second nut move up and down to enable a second lifting cylinder and a first lifting cylinder in a main cylinder to ascend and descend freely; the platform is controlled to ascend and descend in a spiral grading transmission vertical lifting mode, safety and reliability are achieved, outdoor operation is greatly facilitated, and the obvious effects of improving the operation quality, shortening the operation time and providing operation safety guarantee are achieved.
