The utility model relates to a hydraulic support column jack unbalance loading test stand, including the support body for pressing from both sides the loading needling and the loading pile cap of tight loading stand, being used for pressing from both sides tightly the unbalance loading needling and the unbalance loading pile cap of experiment stand, both sides all are equipped with the guide railaround the support body, loading needling and support body front end are fixed, around the loading pile cap both ends be equipped with respectively with guide rail sliding connection's slider, on unbalance loading needling and unbalance loading pile cap are fixed in the guide arm respectively, the guide arm both ends with guide rail sliding connection, the support body rear end all is connected through the thimble slant with the unbalance loading needling with unbalance loading pile cap and loading pile cap. The utility model discloses an outer load atress is the atress circumstances of the real work face of simulating well, reaches the tentation data and becomes more and more actual nature. Can the quick test go out load and the qualification rate that production was equipped in hydraulicsupport column jack manufacture process to durability test and unbalance loading pressure test can be through this equipment simultaneously to design bug and simulation unbalance loading load that discovery was in time equipped.
