The invention discloses an upper pivot body device for fixing construction machinery, and particularly relates to the field of construction machinery. The upper pivot body device for fixing the construction machinery comprises a fixed platform and an upper rotating table. The upper rotating table is rotatably arranged at the top of the fixed platform, and the top of the fixed platform is detachably connected with an adjusting seat; a base is fixedly arranged in the adjusting seat, a connecting ring is fixedly arranged at the bottom of the upper rotating table, and the connecting ring is movably arranged at the top of the adjusting seat; and a movable sliding rail is movably arranged at the top of the base, a movable ring is slidably arranged at the top of the movable sliding rail, the movable ring is located at the bottom of the connecting ring, a ball screw is arranged on one side of the movable sliding rail, and the ball screw is located on one side of the base. According to the upper pivot body device for fixing the construction machinery, the adjusting seat is arranged, the position of the upper rotating table can be automatically locked and released, a first friction plate isin contact with a second friction plate, the upper rotating table can be firstly frictionally decelerated, limiting plates are separately parallel to adjacent upper blocking plate and lower blocking plate, the roles of limiting and blocking are played, and the overall operation process is more simple and convenient.
