Technical Field

[0001] The utility model belongs to the technical field of wind power tower barrel lifting tools, and particularly relates to a wind power tower barrel hoisting clamp. Background Technique

[0002] The wind power tower barrel, namely the tower pole of wind power generation, mainly plays a supporting role in the wind power generating set and absorbs the vibration of the unit at the same time. During the installation of the wind power tower barrel, a crane is used to complete the hoisting work of the wind power tower barrel, so the wind power tower barrel hoisting clamp is particularly important.

[0003] At present, since the two ends of the wind power tower barrel are in the form of connecting flanges, the hoisting clamp generally directly uses a plurality of bolts to fix with the connecting flange. However, just because the two are connected by a plurality of bolts, the overall disassembly and assembly process of the hoisting clamp is time-consuming and laborious. Therefore, a wind power tower barrel hoisting clamp is provided. Content of the Utility Model

[0024] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a wind power tower barrel hoisting clamp of the present utility model with reference to the accompanying drawings.

[0025] As Figures 1-4 shown, a wind power tower barrel hoisting clamp of the present utility model includes a main chain arm 100 and two sub-chain arms 200 respectively located at both ends of the main chain arm 100. The main chain arm 100 is located on the outer surface of the connection flange of the wind power tower barrel. Both ends of the main chain arm 100 are rotatably arranged with the two sub-chain arms 200 through second pins 403 respectively. The outer surface of the sub-chain arm 200 is in contact with the outer surface of the connection flange of the wind power tower barrel. In this device, it further includes: a rotary fixing mechanism 400. Rotary fixing mechanisms 400 are arranged on both the main chain arm 100 and the sub-chain arm 200 respectively, and are respectively used to stabilize the main chain arm 100 and the sub-chain arm 200.

[0026] Specifically, the rotary fixing mechanism 400 includes a main side plate 401 arranged on one side of the main chain arm 100 and a sub-side plate 402 arranged on the other side of the main chain arm 100. The main side plate 401 and the sub-side plate 402 are in corresponding positions, and the main side plate 401 and the sub-side plate 402 have the same structure. Both the main side plate 401 and the sub-side plate 402 are connected to the main chain arm 100. The main side plate 401 is designed in an isosceles trapezoid structure. The rotary fixing mechanism 400 further includes an insertion cylinder 406 arranged on the outer surface of the sub-side plate 402 and located at the position of the round hole of the connection flange, and a pin 405 arranged on the inner surface of the main side plate 401.
