Hydro-pneumatic spring testbed position hydraulic adjustment device with locking function

The invention belongs to the technology field of experiment science, and specifically relates to a hydro-pneumatic spring testbed position hydraulic adjustment device with locking function. The device comprises: a position adjustment oil cylinder, a hydraulic oil supply system, a guide column and a hydraulic locking device; compared with the prior art, the device is used for conveniently moving a hydro-pneumatic spring testbed actuator support up and down in height direction and completing self-locking fixing when the guide column is adjusted to a position needed by the experiment, so that the distance adjustment between the actuator support and the fixed support is realized, experiment requirements of different length series hydro-pneumatic spring are met, and the device is safe and reliable. 本发明属于试验科学技术领域，具体涉及种带闭锁功能的油气弹簧试验台位置液压调整装置。其包括：位置调整油缸、液压供油系统、导向柱、液压闭锁装置；与现有技术相比较，利用本发明的带闭锁功能的油气弹簧试验台位置液压调整装置，可便捷的进行油气弹簧试验台作动器支架延导向柱在高度方向的上下移动并在调整到试验需位置时完成自锁固定，从而实现了作动器支架和固定支座之间的距离调整，满足不同长度系列油气弹簧的试验要求，并且安全可靠。
