Description

Technical Field

[0001] The utility model relates to a special tool for turning over a mixing tower top ring. Background Art

[0002] Concrete towers are widely used in the development and construction of wind turbine hybrid towers both domestically and internationally. They are a crucial component of wind turbine hybrid towers (concrete-steel hybrid towers). Concrete towers are primarily manufactured in either segmented or full-circle configurations. The concrete tower top ring (the top section of the concrete tower) connects to the steel tower. Due to the sudden change in stiffness at the connection and the relatively small cross-section of the concrete tower top ring, which is subject to significant stress, it is typically cast as a full-ring structure, while meeting transportation and hoisting requirements. After casting, the concrete tower top ring requires rotation. The Chinese patent application number 202321505013.5 discloses a precast concrete tower turning device, which is characterized by comprising: a support base (1); a placement frame (2) arranged at the top of the support base (1); a connecting tube arranged between the placement frames (2); a tower tube (6) arranged inside the connecting tube; a transmission wheel (5) arranged at both ends of the connecting tube; and a turning mechanism arranged at the top of the support base (1) and in contact with the transmission wheel (5). The precast concrete tower turning device realizes the effect of rotating the transmission wheel through the setting of the turning mechanism and the transmission wheel, so that the connecting tube can achieve the effect of turning 180 degrees under the action of the transmission wheel. However, due to the high weight of the entire mixed tower ring, high requirements are placed on the steel materials of the supporting base 1, the placement frame 2 and the cylinder 4, and the processing and manufacturing are difficult. In addition, the precast concrete tower turning device occupies a large area, and the mixed tower top ring is relatively dangerous when turning over. It cannot adapt to the current high-cost and short-term construction situation, which seriously affects the construction period and economic benefits. Utility Model Content
