Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] Such as Figure 1~2 As shown, a prefabricated concrete tower segment assembly platform includes a central frame 1, a connecting section 2, and a support beam 3. The inner end of the connecting section 2 is welded to the central frame 1, and the outer end is connected to the support beam 3 through flanges 10 bolts, and the three constitute the main structure of the device. A series of limiting and positioning pin holes 5 are arranged on the panel 4, and positioning pins 6 are inserted to form a limiting and positioning system of the device. The 16 said leveling feet 7 arranged at the bottom of the center frame and the support beam constitute the leveling system of the device. After the concrete tower segment 9 is hoisted onto the device, the leveling and assembling process of the tower segment can be quickly realized through t...

The invention provides a fabricated concrete tower tube piece assembly platform and assembly method. The fabricated concrete tower tube piece assembly platform comprises a center frame, connecting sections, supporting beams, supporting panels, limiting positioning pin holes, positioning pins, leveling supporting feet, base plates and the like. The octagonal center frame and the eight supporting beams are connected through the connecting sections to form a spliced platform body structure. The supporting panels are welded to the top faces of the supporting beams, a series of limiting positioningpin holes are formed in the supporting panels, and the positioning pins are inserted to achieve rapid and accurate positioning of concrete tower tube pieces. The leveling supporting feet are arrangedat the bottoms of edge beams of the center frame and the bottoms of the outer ends of the supporting beams and serve as supporting supports and leveling devices of the platform. The base plates are arranged at the bottoms of the leveling supporting feet and used for dispersing upper concentrated loads and reducing local settlement of a foundation. According to the fabricated concrete tower tube piece assembly platform and assembly method, rapid and accurate assembly of the fabricated concrete tower tube pieces in the technical field of wind power can be realized, the concrete tower rapid construction concept of instant assembly and instant hoisting is embodied, and a quite excellent technical scheme for assembly construction of the fabricated concrete tower tube pieces prefabricated in afragmentation manner is achieved.
Description
technical field [0001] The invention belongs to the technical field of onshore wind power concrete towers, and in particular relates to a fabricated concrete tower segment assembling platform and an assembling method. Background technique [0002] With the further development and utilization of wind resources in my country, wind turbines are gradually developing towards high power and high altitude. The traditional wind power flexible all-steel tower technology has been difficult to meet the needs of large rigidity and large diameter wind turbine towers. In recent years, with the promotion of prefabricated concrete technology in my country, the application of segmental prefabricated concrete towers in the field of wind power generation has become increasingly common, effectively making up for the shortcomings of low stiffness and small diameter of flexible steel towers. However, the speed and accuracy of the assembly process of the prefabricated concrete tower segments great...
