Abstract

The invention discloses a three-degree-of-freedom lifting device directly driven by a hydraulic pump, which belongs to the field of fluid pressure control mechanisms and includes a top plate, a bottom plate, and a diverter valve block fixed at the center of the bottom plate. The energy device is equipped with three sets of lifting mechanisms with the same structure; the upper ends of the three sets of lifting mechanisms are connected to the top plate, and the lower ends are connected to the bottom plate; the diverter valve block is connected to the hydraulic pumps of the three sets of hydraulic drive systems with the same structure and independent of each other through pipelines; The hydraulic pump of each hydraulic drive system controls the lifting mechanism of the corresponding group, and serves as the individual oil source of the lifting mechanism of the group. The device is not only suitable as an auxiliary tool for lifting and moving heavy objects, vehicle maintenance and other work, but also can be carried for emergency occasions such as field vehicle failure maintenance or towing.

Description

technical field [0001] The invention belongs to the field of fluid pressure control mechanisms, and in particular relates to a three-degree-of-freedom lifting device directly driven by a hydraulic pump. Background technique [0002] Whether in the workplace or at home, people will inevitably encounter occasions where heavy objects such as furniture and equipment need to be moved. Even in outdoor activities, the lifting and moving of large items often bring a lot of trouble to people, such as vehicle maintenance and lifting. In similar daily applications, if the manpower burden can be effectively reduced with the help of appropriate power tools, it will bring great convenience to people's lives. In order to meet such needs, lifting and moving devices must have small size, simple structure, easy portability and flexible operation. At the same time, due to the need to save manpower to a great extent, power equipment is essential, and under the condition of both mobility and p...
