Abstract

The invention relates to the field of lifting equipment, in particular to a vehicle-mounted hoist. It includes a vehicle, a turntable and a boom. There is a sling along the length of the boom. One end of the sling is provided with a hook, and the other end is fixedly connected to the coil lifting mechanism on the turntable. A slewing device for driving the turntable to rotate horizontally is provided between the vehicle-carrying frames. The coil lifting mechanism includes a casing fixed on the turntable and a first rotating shaft and a second rotating shaft that are arranged in the inner cavity of the casing and are parallel to each other. and the third shaft, the first shaft is fixed with the first gear and the first motor, the second shaft is fixed with the second gear and the roller, the third shaft is fixed with the third gear and the fourth gear, on the third An anti-drop mechanism is arranged between the rotating shaft and the casing. The invention is flexible in use and has the function of preventing falling of lifting objects, which is convenient for improving the lifting efficiency and the safety in the lifting process.

Description

technical field [0001] The invention relates to the field of lifting equipment, in particular to a vehicle-mounted hoist. Background technique [0002] The basic task of hoisting machinery is to vertically lift heavy objects, and to make heavy objects move horizontally in a short distance to meet the requirements of heavy object loading and unloading, reloading, installation and other operations. Hoisting machinery is an indispensable and important mechanical equipment for modern production. It is of great significance to reduce heavy physical labor, improve labor productivity, realize mechanization and automation of production process, and improve people's material and cultural life needs. Hoisting machinery is widely used in various industrial sectors such as industrial and mining enterprises, port terminals, station warehouses, construction sites, ocean development, and space navigation. work. [0003] The hoist in the prior art is often fixed in form and inconvenient t...
