Problems solved by technology

[0004] Because the pressure of the high-pressure conventional oil tank is greater than that of the traditional hydraulic cylinder, the pipelines and various sealing parts of the aforementioned hydraulic system need to withstand greater pressure, so the possibility of leakage failures also increases accordingly

Abstract

The invention provides rapid erecting equipment. The rapid erecting equipment comprises a base part, an erecting arm, a hydraulic system and a recoil power device. The base part is hinged to the first end of the erecting arm through a first hinge shaft. The hydraulic system comprises a hydraulic control mechanism and a hydraulic cylinder; the recoil power device is arranged on the erecting arm; when the recoil power device works to generate jet flow, the erecting arm rotates around the first hinge shaft in the first direction, and the hydraulic cylinder extends; and in the extension process of the hydraulic cylinder, the hydraulic control mechanism injects oil liquid into a first oil cavity of the hydraulic cylinder to ensure that the first oil cavity is always in a state of being completely filled with the oil liquid. Power provided by the recoil power device can enable the erecting arm and the hydraulic system to be matched to achieve erecting of the erecting arm, and the erecting speed of the erecting arm is guaranteed. The oil pressure in the hydraulic system can be kept at a relatively small value, and the problem that in the prior art, the oil leakage fault occurrence probability of the hydraulic system is increased due to the fact that the oil pressure is too large is solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a quick erecting device. Background technique [0002] In order to meet the needs of rapid deployment, the hydraulic cylinders in the hydraulic systems of erecting (lifting) equipment such as fire ladders and missile launching vehicles should be able to quickly extend. [0003] At present, in order to realize the rapid elongation of the hydraulic cylinder, the hydraulic system of the existing rapid erection system is provided with a high-pressure oil supply branch; During the quick erection function, the oil supply branch communicates with the oil inlet chamber of the hydraulic cylinder, and the hydraulic oil flows into the oil inlet chamber from the high-pressure energy storage tank under high pressure. [0004] Because the pressure of the high-pressure conventional oil tank is greater than that of the traditional hydraulic cylinder, the pipelines and various sealing...
