Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0037] A high-thrust high-speed hydraulic cylinder, including a high-speed hydraulic cylinder, a piston accumulator, and a pressure boost sensor. The high-speed cylinder piston rod is installed at one axial end of the hydraulic cylinder, and the piston accumulator is connected in series at the other axial end of the hydraulic cylinder. The piston accumulator increases the push-out speed of the piston rod;

[0038] In order to facilitate the description of this embodiment, the attached figure 1 The direction shown is for illustration, the left side is the rear part, and the right side is the front part. The specific structure is:

[0039] The main body of the hydraulic cylinder is a sealed cavity arr...

Abstract

The invention relates to a large-thrust high-speed hydraulic cylinder. A hydraulic cylinder body is a sealed cavity which is transversely arranged. A high-speed cylinder barrel is fixedly arranged at the front end of the hydraulic cylinder body in an axial extending manner. A high-speed cylinder piston rod is coaxially sleeved with the high-speed cylinder barrel. The high-speed piston rod coaxially slides in a sealed manner in a high-speed cylinder rod cavity. An energy accumulator piston rod penetrating an energy accumulator gas cavity and a supercharger cavity is coaxially installed in the hydraulic cylinder body. An energy accumulator piston is fixedly arranged at the end portion, at the front end of the energy accumulator gas cavity, of the energy accumulator piston rod. The energy accumulator piston is installed in the hydraulic cylinder body in a sealed and sliding manner. An energy accumulator liquid cavity is formed between the energy accumulator piston and the high-speed cylinder piston rod. A pressure cylinder piston is coaxially manufactured on the energy accumulator piston rod in the supercharger cavity. The pressure cylinder piston is installed in the supercharger cavity in a sealed and sliding manner. By means of the high-thrust high-speed hydraulic cylinder, through the manner that a piton type energy accumulator and the high-speed hydraulic cylinder are directly connected in series, high-speed output of large thrust of the high-speed cylinder can be achieved.

Description

technical field [0001] The invention belongs to the hydraulic field, in particular to a high-thrust high-speed hydraulic cylinder and a working method thereof. Background technique [0002] In various engineering applications such as crash tests, high-speed friction tests or high-speed delivery devices, it is usually necessary to accelerate a large-mass test platform or test object to quickly reach a higher working speed, which puts forward a new challenge for the acceleration system of the test platform. Very demanding job. The hydraulic system has the advantages of large thrust and compact structure, and is an ideal test acceleration system. However, the existing traditional hydraulic cylinder is used as a power source, and the movement speed of its piston rod is limited by many aspects such as liquid flow, so it is difficult to provide high output speed. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior...
