Description

Technical Field

[0001] This invention relates to the field of mixed tower construction technology, and more specifically, to an operating platform for mixed tower construction based on low-fan zone. Background Technology

[0002] Hybrid towers in low-wind areas refer to hybrid tower structures located in areas with low wind speeds. These tower structures are commonly used in wind power generation, especially in regions with low natural wind speeds and relatively scarce wind resources. In these areas, traditional wind turbine towers may not meet the demands for efficient energy conversion; therefore, hybrid tower designs have emerged. Hybrid towers combine the advantages of various materials and structures, aiming to improve the stability and load-bearing capacity of the tower while optimizing wind capture efficiency to adapt to the unique environment of low-wind areas. By employing advanced engineering technologies and design concepts, hybrid towers in low-wind areas can maintain high power generation efficiency even at low wind speeds, providing a new solution for the development of the wind power industry.

[0003] According to patent document CN107697818A, a method and special construction equipment for constructing prestressed concrete wind turbine tower walls are disclosed. The method involves installing wall-attaching devices, special construction equipment, and a 2t double-cantilever flat-top tower crane on a pre-cast foundation. Workers are transported to a circular telescopic construction platform via a personnel elevator. A multi-layered circumferential horizontal transport platform is formed by the circular telescopic construction platform, the formwork lifting platform, and the inner suspension platform within the special construction equipment for reinforcing steel binding, concrete pouring, and the assembly and disassembly of inner and outer arc-adjusting formwork. The inner and outer arc-adjusting formwork is reused layer by layer, and the special construction equipment and climbing guide rails alternately lift the tower until the concrete wall of the wind turbine tower is completed. During the lifting process, the jacking device of the circular telescopic construction platform is adjusted in a timely manner as the radius of the wind turbine tower decreases, and the formwork lifting platform is retracted. When the construction approaches the top of the wind turbine tower, the inner suspension platform is removed, and the drum ring of the circular telescopic construction platform is connected to the corbel support pre-embedded during the construction of the wind turbine tower top. A temporary scaffolding platform is then erected to complete the construction of the wind turbine tower top wall.

[0004] After the completion of the fan tower construction, if maintenance is required in the subsequent stages, rebuilding the construction platform will consume a lot of time and resources. Usually, people use lifting equipment or ladders to perform high-altitude operations. However, this method has several problems. Since the tower is usually designed to be cylindrical, it is difficult for lifting equipment to be positioned accurately because they cannot fit tightly against the surface of the tower. This mismatch not only causes safety hazards but also significantly reduces work efficiency. Summary of the Invention

The tops of the two V-shaped rotating rods 228 are fixedly connected to the rear sides of the outer walls of the two columnar push rods 224. The bottoms of the two V-shaped rotating rods 228 are rotatably connected to the rear sides of the two V-shaped rotating rod push-pull rods 229.

[0034] When construction of the hybrid tower is required, the entire device is first moved to the vicinity of the hybrid tower using the lifting device 1. Then, the workers climb to the inside of the construction frame body 221 using a ladder. After that, the hydraulic push rod 3111 is activated. The extension and retraction of the hydraulic push rod 3111 drives the inverted T-shaped push-pull block 3112 to move within the slide plate 319, thereby causing the flipping rotating rod 3114 to rotate around the flipping rotating rod connecting block 3113. The flipping of the flipping rotating rod 3114 drives the positioning rotating plate 310 to rotate. Through the two rotating blocks 39 at the bottom and the columnar rotating rod 34 on the inner wall of the rotating block 39, the positioning rotating plate 310 rotates around the two columnar rotating rod connecting blocks 33 as the axis. When the columnar rotating rod 34 rotates, the two guide rotating rods 35 rotate. Since the inner sides of the two guide rotating rods 35 are slidably connected... The inner walls of the two arc-shaped guide slide bars 38 allow the guide rotating rod 35 to slide along the trajectory of the arc-shaped guide slide bars 38 while rotating, increasing the stability and controllability of the rotation. As the positioning rotating plate 310 rotates, its top will gradually approach the mixed tower structure until it is tightly fitted. At this time, the second hydraulic push rod 313 is activated, and the push block 314 moves forward under hydraulic action. Through the transmission of the hinge block 315 and the rotating rod 316, the two columnar rotating blocks 311 drive the clamping plate 312 to move inward, tightly clamping the mixed tower structure, thus achieving stable positioning of the construction platform. In addition, when it is necessary to lift the construction platform 2 and the positioning mechanism 3, the restriction of the two clamping plates 312 on the tower body can be released, and the construction platform 2 and the positioning mechanism 3 can be lifted as a whole through the lifting device 1.

[0035] Simultaneously, when the two guide rods 35 rotate, they drive the abutment rod 36 to rotate on the inner wall of the elliptical slide plate 2112. As the abutment rod 36 rotates, it abuts against the elliptical slide plate 2112, pushing the push rod 2110 to move backward. When the push rod 2110 moves backward, it meshes with the gear 212 through the multiple toothed blocks 2111 set at the top. The rotation of the gear 212 drives the second abutment block 214 to rotate and abut against the elliptical slide plate 215 to move downward. This causes the inverted U-shaped positioning rod 217 to move downward along the guide block 216 and insert into the limiting groove 219 opened in the limiting block 218. This ensures the stability of the entire construction platform on the lifting device, avoids the construction platform from shaking or deviating during operation, and further improves the safety and efficiency of construction.

[0036] At the same time, as the two push rods 2110 move backward, they simultaneously drive the two V-shaped rotating push rods 229 to move backward. When the two V-shaped rotating push rods 229 move backward, since the bottom of the V-shaped rotating rod 228 is rotatably connected to the rear of the V-shaped rotating push rod 229, the V-shaped rotating rod 228 will rotate around its rotational connection point with the upright plate 225. Meanwhile, since the middle of the outer wall of the columnar push rod 224 is movably connected to the upright plate 225, and the top of the columnar push rod 224 is fixed... The fixed connection is located at the bottom rear side of the construction frame push plate 222. Therefore, as the V-shaped rotating rod 228 rotates, the columnar push rod 224 will drive the construction frame push plate 222 and the entire construction frame body 221 to slide forward along the top of the base plate body 211 until the front side of the construction frame body 221 approaches the mixed tower structure. This design not only enables the construction frame body 221 to automatically adjust its position to adapt to mixed tower structures of different diameters, but also provides a convenient working space for workers during construction.

[0037] Furthermore, the groove plate 319, the rotating flip rod 3114, and the positioning plate 310 are designed to allow the entire positioning mechanism 3 to be flexibly adjusted according to the actual conditions of the mixed tower structure, ensuring that the construction platform 2 can be stably attached to the mixed tower structure and avoiding safety hazards caused by the shaking or displacement of the construction platform. At the same time, the elliptical groove vertical plate 2112, the elliptical groove horizontal plate 215, and the inverted U-shaped positioning rod 217 are designed to further improve the stability of the entire construction platform on the lifting device 1, ensuring the smooth progress of the construction process.

[0038] Working principle of this invention: When construction of the hybrid tower is required, the entire device is first moved to the vicinity of the hybrid tower using the lifting device 1. Then, the workers climb to the inside of the construction frame body 221 using a ladder. The hydraulic push rod 3111 is then activated. The extension and retraction of the hydraulic push rod 3111 causes the inverted T-shaped push-pull block 3112 to move within the sliding plate 319, thereby causing the flipping rotating rod 3114 to rotate around the flipping rotating rod connecting block 3113. The flipping of the flipping rotating rod 3114 causes the positioning rotating plate 310 to rotate. This rotation is achieved through the two rotating blocks 39 at the bottom and the columnar rotating rod 34 on the inner wall of the rotating blocks 39, causing the positioning rotating plate 310 to rotate around the two columnar rotating rod connecting blocks 33 as its axis. When the columnar rotating rod 34 rotates, it causes the two guide rods to rotate. As rod 35 rotates, the inner sides of the two guide rods 35 are slidably connected to the inner walls of the two arc-shaped guide groove rods 38, allowing the guide rods 35 to slide along the trajectory of the arc-shaped guide groove rods 38 while rotating, increasing the stability and controllability of the rotation. As the positioning plate 310 rotates, its top gradually approaches the hybrid tower structure until it is tightly fitted. At this point, the second hydraulic push rod 313 is activated, and the push block 314 moves forward under hydraulic pressure. Through the transmission of the hinge block 315 and the rotating rod 316, the two columnar rotating blocks 311 drive the clamping plate 312 to move inward, tightly clamping the hybrid tower structure and achieving stable positioning of the construction platform. In addition, when it is necessary to raise or lower the construction platform 2 and the positioning mechanism 3, the two clamps are released. The limiting position of plate 312 on the tower body can be achieved by lifting the construction platform 2 and positioning mechanism 3 as a whole through the lifting device 1. At the same time, when the two guide rods 35 rotate, they drive the abutment rod 36 to rotate on the inner wall of the elliptical slide plate 2112. As the abutment rod 36 rotates, it abuts against the elliptical slide plate 2112, pushing the push rod 2110 to move backward. When the push rod 2110 moves backward, it meshes with the gear 212 through the multiple toothed blocks 2111 set at the top. The rotation of the gear 212 drives the second abutment block 214 to rotate and abut against the elliptical slide plate 215 to move downward. This causes the inverted U-shaped positioning rod 217 to move downward along the guide block 216 and insert into the limiting groove 21 of the limiting block 218. Within 9, as the two push rods 2110 move backward, they simultaneously drive the two V-shaped rotating push rods 229 to move backward. When the two V-shaped rotating push rods 229 move backward, since the bottom of the V-shaped rotating rod 228 is rotatably connected to the rear side of the V-shaped rotating push rod 229, the V-shaped rotating rod 228 will rotate around its rotational connection point with the upright plate 225. Simultaneously, since the middle of the outer wall of the columnar push rod 224 is movably connected to the upright plate 225, and the top of the columnar push rod 224 is fixedly connected to the rear bottom of the construction frame push plate 222, as the V-shaped rotating rod 228 rotates, the columnar push rod 224 will drive the construction frame push plate 222 and the entire construction frame body 221 to slide forward along the top of the base plate body 211.Until the front side of the main construction frame 221 is close to the mixed tower structure.
