Description

Technical Field

[0001] The present invention belongs to the technical field of hoisting, and relates to the hoisting and turning-over of concrete tower barrels, in particular to a hoisting and turning-over device for concrete tower barrels. Background Art

[0002] Concrete tower barrels are structures used in various engineering constructions, such as wind power generation, communication towers, water storage towers, etc. They are usually made of concrete materials and have high strength and durability. Concrete tower barrels have strong compressive and shear resistance capabilities and are suitable for bearing large external loads such as wind loads and snow loads. Concrete materials have good corrosion resistance and weather resistance and can be used for a long time in harsh environments. The construction of concrete tower barrels usually adopts the cast-in-place or precast method. The cast-in-place process can be poured on-site with strong adaptability; the precast process can be fabricated in a factory to improve construction efficiency and quality control. When designing a concrete tower barrel, factors such as load analysis, foundation treatment, seismic design, and durability need to be considered to ensure its safety and economy. The design and construction technology of concrete tower barrels are constantly developing. With the progress of material science and technology, higher-performance concrete materials and more advanced construction processes may emerge in the future.

[0003] After retrieval, for example, a Chinese patent document discloses a hoisting and turning-over device and a hoisting and turning-over method for a concrete tower barrel, with the application number: CN106586811A. The hoisting and turning-over device includes: a hoisting frame main body, an upper suspension point for connecting to a hoisting device is arranged on the upper part of the hoisting frame main body, and four lower suspension points for connecting to the concrete tower barrel are symmetrically arranged on the lower part of the hoisting frame main body. The four lower suspension points include a pair of main suspension points and a pair of secondary suspension points that are symmetrically arranged relative to the upper suspension point respectively; a pair of tower barrel hoisting ropes, the upper ends of which are respectively connected to a pair of main suspension points, and the lower ends of the pair of tower barrel hoisting ropes are connected to side lifting lugs on the outer peripheral surface of the concrete tower barrel. The side lifting lugs are located on the outer peripheral surface of the concrete tower barrel along the radial direction of the concrete tower barrel; a first chain block and a second chain block, the upper ends of which are respectively arranged on a pair of secondary suspension points, and the lower ends of the first chain block and the second chain block are respectively connected to an upper lifting lug at the upper end of the concrete tower barrel and a lower lifting lug at the lower end of the concrete tower barrel.

[0004] The hoisting and turning-over device and the hoisting and turning-over method for a concrete tower barrel disclosed in this patent still have some drawbacks. During use, the ropes can only be fixed at one end of the concrete tower barrel, resulting in an inability to stably turn the concrete tower barrel during the hoisting process, and it is also inconvenient to turn both ends of the concrete tower barrel, thereby reducing the use effect of this device.

Knobs 53 are rotatably sleeved on the surfaces of the two connecting cylinders 52. The two knobs 53 respectively cooperate with the two connecting cylinders 52. Connecting rings 54 are fixedly connected to the mutually remote sides of the two knobs 53 for rotating the knobs 53, so that the connecting rings 54 slide on the surfaces of the connecting cylinders 52, and then the fixing plate 51 can be stabilized between the two fixed pieces 11.

[0025] In summary, in the present invention, during actual use, through the arrangement of two pairs of connecting pieces 1, both ends of the concrete tower barrel body 6 can be fixed respectively. Subsequently, it is convenient to lift the concrete tower barrel body 6, and during the lifting process of the concrete tower barrel body 6, the two first steel wires 2 can be pulled, so as to facilitate the rotation of the concrete tower barrel body 6, enabling any end of the concrete tower barrel body 6 to be erected, thereby improving the convenience and stability of the device. When in use, the two pairs of connecting pieces 1 can be first installed at both ends of the concrete tower barrel body 6, and the two ends of the two pairs of connecting pieces 1 are fixed by fixing bolts 12 and fixing nuts 13, making the two pairs of connecting pieces 1 closer and more fitting on the surface of the concrete tower barrel body 6. While installing the two pairs of connecting pieces 1, fixing plates 51 are respectively installed on the surfaces of each fixing bolt 12. Subsequently, according to the distance between every two fixing pieces 11, the two knobs 53 are rotated to make the two connecting rings 54 slide away from each other, so that the two connecting rings 54 are respectively in contact with the two fixing pieces 11, making the fixing plate 51 more stable between the two fixing pieces 11. Then, the hooks 21 on the two first steel wires 2 are respectively hung on the third fixing rings 5 on the surfaces of the four fixing plates 51, and the concrete tower barrel body 6 can be lifted. During the lifting process of the concrete tower barrel body 6, the driving motor 29 can be driven to drive the worm 28 to rotate. With the cooperation of the worm gear 27, the rotating shaft 26 and the two pulleys 22 will be driven to rotate simultaneously. At this time, the two first steel wires 2 will be slid, and the concrete tower barrel body 6 will be flipped simultaneously, so as to facilitate the adjustment of the angle of the concrete tower barrel body 6, thereby improving the use effect of the device.
