Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation facilities, and in particular to a construction platform for installing a wind power concrete tower. Background Art

[0002] As a clean energy technology, wind power generation has been widely used in Northeast, North China and Northwest my country, which have good wind resources. At the same time, the power of wind turbines is increasing, which makes the diameter of wind rotors larger and the height of towers higher. At present, the tower height of domestic onshore wind turbines has reached 120~160m. With the increase of tower height, traditional steel towers are difficult to meet the construction requirements of large-section high towers due to their high cost and transportation difficulties. Precast concrete towers can economically build large wind turbines.

[0003] Concrete towers are generally prefabricated in sections and then transported to the site for hoisting. That is, they are divided into several sections along the height direction of the tower. During construction, a construction platform is set up inside the tower to install the hoisted sections. The construction platform rises as the tower rises, and workers can perform construction operations on the top and inner wall of the sections from the top of the platform. However, the sections to be installed will be skewed during hoisting, and the alignment and docking process with the installed sections requires the support of multiple workers, which is time-consuming and labor-intensive, and has low installation efficiency.

According to the distance of each point, it can be determined whether the end faces of the two cylinder sections are parallel.

[0052] When the platform is in use, a lifting point is embedded inside the concrete cylinder segment during casting and forming. The platform is suspended from the embedded lifting point on the top of the cylinder segment by a steel cable or chain.

[0053] When a construction platform for installing a wind power concrete tower is in use, the device is connected to the hanging point in the installed cylinder segment through a steel cable or chain, the platform is adjusted to match the diameter of the corresponding installed cylinder segment, and the expansion hydraulic cylinder 131 is started. The piston rod of the expansion hydraulic cylinder 131 drives the expansion piece 21 to extend outward. At this time, the gap between the two adjacent expansion pieces 21 slowly increases. As the expansion piece 21 moves, the outer push rod 212 above the expansion piece 21 pulls the sleeve rod 251 to move, and the return spring 2521 stretches and drives the movable rod 252 to move. The movable rod 252 drives the moving block 24 to slide in the arc groove 2221. At the same time, the moving block 24 pulls the inner push rod 222 to move outward. The inner push rod 222 drives the inner expansion plate 221 to slide out of the sliding hole 112. The inner expansion plate 221 blocks the gap between the two expansion pieces 21, so that the end of the abutment wheel 23 abuts against the inner wall of the cylinder segment.

[0054] The abutting hydraulic cylinder 29 is started, and the piston rod of the abutting hydraulic cylinder 29 is extended, so that the abutting block 291 abuts against the inner wall of the installed barrel section to ensure the stability of the support assembly 1. The jacking hydraulic cylinder 32 is started, and the piston rod of the jacking hydraulic cylinder 32 is extended, driving the driving ring 34 to rise. The driving ring 34 drives the support rod 36 to rotate upward through the inclined rod 35. The angle between the support rod 36 and the column 33 becomes larger, so that the crane lifts the barrel section to be installed above the installed barrel section and slowly drops it. After the barrel section to be installed is sleeved on the outside of the support rod 36, the jacking hydraulic cylinder 32 is retracted, and the driving ring 34 falls to a suitable position, driving the support rod 36 to rotate downward until the roller at the end of the support rod 36 abuts against the inner wall of the barrel section to be installed. At this time, multiple rangefinders 2 7. The distance between the upper end face of the cylinder segment where the platform is located and the lower end face of the cylinder segment to be installed is measured. When the data of multiple distance meters 27 are inconsistent, the roller on the corresponding support rod 36 is driven to rotate forward or reverse, and the hoisting cylinder segment is driven to move upward or downward in the corresponding direction for fine adjustment until the data of multiple distance meters 27 are consistent, which indicates that the lower end face of the hoisting cylinder segment is kept horizontal. Then the rotating motor 15 is started, and the output shaft of the rotating motor 15 drives the worm 151 to rotate, and the worm gear 16 meshing with the worm 151 rotates, and the worm gear 16 drives the rotating shaft 311 and the turntable 31 to rotate. The turntable 31 drives the cylinder segment to be installed to rotate through the column 33 and the support rod 36, so as to adjust the installation position of the lower end face of the cylinder segment to be installed to be aligned with the upper end face of the installed cylinder segment.

[0055] Then start the positioning hydraulic cylinder 26, the piston rod of the positioning hydraulic cylinder 26 extends, driving the positioning frame 261 to move upward. When the positioning frame 261 moves to the inner side of the cylinder section to be installed, the positioning hydraulic cylinder 26 stops and starts the positioning motor 2613. The output shaft of the positioning motor 2613 rotates, driving the screw rod 2612 to rotate, and the slide plate 2621 threadedly connected to the screw rod 2612 moves. The slide plate 2621 drives the vertical plate 2623 and the tightening block 263 to move until the tightening block 263 is aligned with the inner wall of the cylinder section to be installed. When the cylinder section to be installed is in contact with the installed cylinder section, the crane is operated to lower the cylinder section to be installed. At the same time, the piston rod of the positioning hydraulic cylinder 26 is retracted and lowered together with the cylinder section to be installed until the cylinder section to be installed is connected with the installed cylinder section. During the falling process, the roller can be driven to roll and connect with the inner wall of the cylinder section to be installed, and cooperate with the tightening block 263 to maintain the stability of the cylinder section to be installed when it falls. After the connection is completed, the staff can carry out subsequent construction on the connection between the two cylinder sections.
