The invention discloses a movable foundation bolt device applied to vibration equipment fixing. The movable foundation bolt device comprises an equipment base of vibration equipment, a support bottom plate, a press ring seat, a foundation bolt with a T-shaped head, annular sealing sleeves and limit blocks, wherein a circular hole is formed in the equipment base; the press ring seat is arranged in the circular hole; oblong holes are formed in the support bottom plate; the annular sealing sleeves are arranged below the oblong holes; the T-shaped head of the foundation bolt with the T-shaped head is located in the annular sealing sleeves, and is arranged at an angle of 90 degrees with the oblong holes of the support bottom plate; a rod part of the foundation bolt with the T-shaped head is located at the middle parts of the oblong holes and in a central hole of the press ring seat; the limit blocks are arranged in the oblong holes in the two sides of the rod part of the foundation bolt with the T-shaped head; and the lower ends of the limit blocks stretch into the annular sealing sleeves. According to the movable foundation bolt device disclosed by the invention, the foundation bolt with the T-shaped head, which is broken due to fatigue, can be conveniently taken out, and then immediately replaced by a new foundation bolt with a T-shaped head; therefore, prolonging for the service life of the vibration equipment is benefited.
