Abstract

The invention belongs to the technical field of hydraulic equipment, and particularly discloses a hydraulic device. The hydraulic device comprises a base and a first sleeve. A big piston rod is arranged on the base. A big piston is arranged on the big piston rod. A second sleeve and a third sleeve are separately arranged on the two sides of the first sleeve. A hemispherical support which is rotatably connected with the first sleeve in a sealing mode is arranged at the upper end of the first sleeve. Sealing plates with sliding holes are arranged at the upper ends of the two sleeves correspondingly. A supporting plate is arranged on the support. The second sleeve and the third sleeve are each internally provided with a small piston and a small piston rod. An upper pipeline, a lower pipelineand a tee joint are arranged on each of the first sleeve and the second sleeve. Valves are arranged on the tee joints. Supporting rods are connected between the valves and the supporting plate. The first sleeve is connected with an oil pump through an oil inlet pipe. The hydraulic device is mainly used for supporting a weight, and the problem that the service life of a hydraulic supporting deviceis shortened due to unbalanced stress is solved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment, and specifically discloses a hydraulic device. Background technique [0002] A hydraulic press is a machine that uses liquid as a working medium to transfer energy to achieve various processes. In addition to being used for forging and forming, hydraulic presses can also be used for straightening, pressing, packaging, briquetting, pressing plates and supporting heavy objects. Hydraulic presses include hydraulic presses and hydraulic presses. [0003] When supporting equipment or objects with a large mass, a hydraulic support device is usually used. A general hydraulic support device has a hydraulic support system, so the strength of its support is greatly limited. [0004] In view of the above problems, Chinese patent CN107191429A discloses a hydraulic support device, including a support base plate, the center of the upper surface of the support base plate is provided with a main ho...
