The invention provides a temporary parking device matched with an oil-gas supporting system for use, which comprises a hydraulic jack, a hydraulic lock valve block, an oil-gas supporting valve block, an additional gas chamber communicating valve block, an additional gas chamber and a negative pressure oil well pump, the hydraulic lock valve block is connected with the hydraulic jack and the oil-gas supporting valve block through a hydraulic pipeline, the additional gas chamber communicating valve block is connected with the additional gas chamber and the oil-gas supporting valve block through a hydraulic pipeline, and the oil inlet end of the negative pressure oil well pump is connected with the oil-gas supporting valve block. According to the device, the position of the test piece can be kept under the conditions that equipment is powered off and an oil source is shut down after test work on the same day is finished, and free boundary simulation of the test piece can be achieved in a short time on the second day. Meanwhile, the temporary parking system can realize an emergency stop protection function to a certain extent, and when the oil-gas supporting system breaks down suddenly and the test piece falls unexpectedly, the vibration exciter connected with the test piece is prevented from being dragged and damaged.
本申请提供一种油气支承系统配套使用的临时停放装置,包括液压千斤顶、液压锁阀块、油气支承阀块、附加气室联通阀块、附加气室和负压抽油泵,液压千斤顶放置于油气支承系统下部的中空承力结构内,液压锁阀块通过液压管路与液压千斤顶和油气支承阀块连接,附加气室联通阀块通过液压管路与附加气室和油气支承阀块连接,负压抽油泵的进油端与油气支承阀块连接。本申请装置可在当天试验工作结束后,在设备断电、油源停机的情况下,实现试验件的位置保持,第二天可在短时间内实现试验件的自由边界模拟。同时本临时停放系统可在一定程度上实现急停保护功能,在油气支承系统突发故障,试验件发生非预期内下落时,避免与试验件连接的激振器被拖拽损坏。
