The invention discloses a longitudinal gravity compensation device with micro-gravity simulation implementation systems and six degrees of freedom for spatial mechanisms, and relates to a gravity compensation device. By the aid of the longitudinal gravity compensation device, the problem of difficulty in implementing longitudinal gravity compensation by an existing gravity compensation mechanism in a scheme when spatial mechanisms are heavy can be solved. The longitudinal gravity compensation device is characterized in that an upper-layer platform, a middle platform and a lower-layer platform of the longitudinal gravity compensation device are sequentially arranged from top to bottom, a central upright column is vertically arranged between the lower surface of the upper-layer platform and the upper surface of the middle platform, the upper end of the central upright column is connected with the lower surface of the upper-layer platform by a ball bearing, the lower end of the central upright column is connected with the upper surface of the middle platform, four compensation systems are arranged on the upper surface of the lower-layer platform to form a square, the middle platform is connected with the lower-layer platform by the four compensation systems, and pneumatic feet are uniformly distributed on the lower surface of the lower-layer platform. The longitudinal gravity compensation device is used in the field of spaceflight.
