Abstract

The invention discloses a lifting hydraulic capstan for a truck-mounted crane of a truck, and relates to engineering machinery. The lifting hydraulic capstan is characterized in that a hydraulic motor provides a power source, is fixed onto a flange plate of a fixing seat, is matched with a brake connecting shaft by a spline and drives the brake connecting shaft to rotate, the brake connecting shaft is connected with a central gear of a planetary gear deceleration system, an inner gear ring drives a reel to rotate, the reel pulls a steel wire rope, and accordingly goods lifting operation is completed. The fixing seat integrates functions of a hydraulic capstan and truck connecting support, functions of a hydraulic motor fixing support, functions of a shell of a brake system and functions of a planetary gear carrier, a ball bearing replaces a pair of tapered roller bearings, advantages of the traditional speed reducer are retained, the requirement on the lifting service performance of the truck-mounted crane can be met, materials are saved, the cost is reduced, the lifting hydraulic capstan is convenient to install and detach owing to the small size and light weight of the lifting hydraulic capstan, and purposes of safety and practicality are achieved.

Description

technical field [0001] The invention relates to a hoisting reducer for a truck-mounted crane. Background technique [0002] Truck-mounted cranes are widely used in various loading and unloading, installation and lifting operations, especially for field lifting, disaster relief and emergency operations, and operations in narrow places such as stations, ports, warehouses, construction sites, etc., because of their flexible, convenient, efficient, safe and reliable Therefore, the truck-mounted crane has a good market prospect in China. As the lifting mechanism of the truck-mounted crane, its role is becoming more and more obvious. The structure of the traditional reducer is relatively complicated and the volume is large. At the same time, the larger the volume, the higher the cost. Therefore, the traditional reducer restricts its development on the truck-mounted crane to a certain extent. Contents of the invention [0003] In order to solve the above-mentioned traditional te...
