Abstract

The invention relates to a jack dynamic testing system comprising a hydraulic constant pressure system and a testboard. The hydraulic constant pressure system is arranged above the testboard, and the hydraulic constant pressure system is provided with a pressure sensor and a displacement sensor. The jack dynamic testing system also comprises a connection support and an operating arm which automatically applies an operating force to a jack, the connection support is arranged on the hydraulic constant pressure system, the connection support is provided with an adjusting device which adjusts the applying angle of the operating arm, and the adjusting device is provided with a self-locking device for locking the adjusting device. The jack dynamic testing system is advantaged in that the operating arm automatically applies the operating force to a jack handle to control ejection of the jack, the jack ejection efficiency is improved, the working intensity of manually cranking the handle to eject the jack is reduced, the safety performance of the jack when the jack is ejected under a load and a constant pressure is improved, the adjusting device adjusts the applying angle of the operating arm to the jack handle, and therefore pressure applied to the jack handle can be effectively adjusted, and the jack dynamic testing system is suitable for testing jacks of different models.

Description

technical field [0001] The invention relates to a jack dynamic test system. Background technique [0002] The jack is mainly used for lifting and supporting heavy objects. Its structure is light and firm, flexible and reliable, and can be carried and operated by one person. Light and small lifting equipment for lifting heavy objects, jacks are widely used in the construction, production, and maintenance of cable engineering, especially in equipment installation, lifting, disassembly, debugging, etc. Stability and reliability will be directly related to the safety of operators and equipment. The Chinese patent with the application number of 200920113597.5 and the application date of 2009.2.9 discloses a dynamic pre-test system for jack loads. During the test, the jack needs to be manually shaken by the operator. The handle is used to push the jack out. Since the top of the jack receives the pressure of the hydraulic system, the jack shakes the jack under load. When the press...
