[0017] Refer to Figure 1 and Figure 2, A main tower longitudinal reinforcement segmented integral hoisting device, comprising a first hoisting member 1 and a second hoisting member 2. The first hoisting member 1 includes a first hoisting frame 1-1, and first steel plates 1-2 are respectively arranged on both sides of the first hoisting frame 1-1. A series of hoisting holes 1-3 for installing longitudinal main reinforcements are formed on the first steel plates 1-2. The second hoisting member 2 includes a second hoisting frame 2-1, and second steel plates 2-2 are respectively arranged on both sides of the second hoisting frame 2-1. A series of hoisting holes 2-3 for installing transverse main reinforcements are formed on the second steel plates 2-2.

[0018] In this embodiment, the first hoisting frame 1-1 is welded by channel steels on both sides and evenly distributed connecting channel steels in the middle. Among them, the upper end of the outer channel steel exceeds the upper end of the inner channel steel, and a connecting section is vertically welded to the upper end of the inner channel steel.

[0019] In this embodiment, the first steel plates 1-2 on both sides of the first hoisting frame 1-1 are welded to the first hoisting frame 1-1. Among them, the upper end of the outer first steel plate 1-2 has an arc transition and can be assembled with the second steel plates 2-2 on the outside of the second hoisting frame 2-1, and the upper end of the inner first steel plate 1-2 has an inclined transition and can be assembled with the second steel plates 2-2 on the inside of the second hoisting frame 2-1.

[0020] In this embodiment, the second hoisting frame 2-1 is welded by channel steels on both sides and evenly distributed connecting channel steels in the middle. Among them, the two ends of the channel steels on both sides are aligned.

[0021] In this embodiment, the second steel plates 2-2 on both sides of the second hoisting frame 2-1 are welded to the second hoisting frame 2-1. Among them, the two ends of the outer second steel plate 2-2 are aligned with the two ends of the second hoisting frame 2-1, and the inner second steel plate 2-2 is located at the middle position of the second hoisting frame 2-1.

[0022] In this embodiment, the hoisting holes 1-3 for installing longitudinal main reinforcements and the hoisting holes 2-3 for installing transverse main reinforcements are formed according to the actual arrangement of the main reinforcements.

[0023] Working principle:

[0024] Before hoisting, according to the arrangement of the main tower longitudinal reinforcements, the main reinforcements are divided into 6 block segments according to the plane position, and the hoisting device is processed according to the main reinforcement spacing and the number of main reinforcements in the divided block segments; the hoisting device is processed by using channel steels and steel plates, and the size of the steel bar holes is 1 cm larger than the diameter of the steel bars;

[0025] Then, the main reinforcements are installed on the hoisting device in the steel bar hoisting area, and the main reinforcements are hoisted by using the characteristic that the steel bars can pass through the steel bar holes while the straight thread sleeves cannot pass through the steel bar holes. Only 6 hoistings are required for the main reinforcements of each segment of the main tower. As Figure 3 shown, in this way, the hoisting efficiency can be effectively improved, the construction progress can be accelerated, and it is applicable to the hoisting of double-limb and multi-limb steel bars, and the hoisting is convenient.
