Embodiment 1

[0024] Embodiment 1: A single-blade hoisting tool for a wind power generating set (see attached figure 1 to attach image 3 ), including the main suspension beam 1 and the end suspension beam 2, the main suspension beam is long, the end suspension beam is T-shaped, the end suspension beam includes the connection beam 4 and the support beam 5, the connection beam is fastened to the main suspension beam, and the connection beam The fastening connection with the main suspension beam is realized through the connection flange. The main suspension beam includes several beam bodies fastened together, and the adjacent beam bodies are connected by connecting flanges. Both ends of the support beam are connected with the electric hoist 6 and the hoisting seat 7, and the main hoisting beam is connected with the hoisting seat and the hoisting seat 8 far away from the end of the connecting beam. , the hook of one electric hoist is connected with one end of the front sling, the front autom...

Embodiment 2

[0026] Embodiment 2: A single-blade hoisting tool for a wind power generating set (see attached Figure 4 ), its structure is similar to that of Embodiment 1, the main difference is that in this embodiment, the connecting beam and the supporting beam are connected to the supporting bottom beam 24, the supporting bottom beam is fastened to the end of the connecting beam, and the supporting beam is supported on the supporting bottom beam On, the rotating pin 25 is connected between the supporting beam and the supporting bottom beam, and the supporting beam can rotate around the rotating pin. The rotating pin has a T-shaped structure, and connecting holes are provided on the supporting beam and the supporting bottom beam. The rotating pin runs through the two connecting holes. The lower end of the rotating pin is connected with a limit nut, and the lower end of the rotating pin is connected with a limit pin to prevent The stop nut slides off the turning pin. Other structures are...

Abstract

The invention discloses a hoisting tool for a single blade of a wind turbine generator system and a hoisting method. The hoisting tool for a single blade of the wind turbine generator system aims at solving the problems of complex structure, high cost and poor universality of hoisting equipment for the single blade of the wind turbine generator system. The invention comprises a main hoisting beamand an end hoisting beam. The main hoisting beam is in a strip shape, the end hoisting beam is in a T shape, the end hoisting beam comprises a connecting beam and a supporting beam, the connecting beam is fixedly connected with the main hoisting beam, both ends of the supporting beam are connected with electric hoists and a hoisting seat, and a hoisting seat and the hanging seat are connected withthe end, away from the connecting beam, of the main hoisting beam. A front hoisting belt is installed between the two electric hoists in a hanging mode, a hook of one of the electric hoists is connected with one end of the front hoisting belt, and a front automatic detacher is connected between a hook of the other electric hoist and the other end of the front hoisting belt. The front hoisting belt is connected with a bracket, and a soft supporting seat is installed on the upper surface of the bracket. An inwards concave arc-shaped structure is arranged on the upper surface of the supporting seat. The hanging seat is connected with a rear hoisting belt and a rear automatic detacher, one end of the rear r hoisting belt is connected with the hanging seat, and the other end of the rear hoisting belt is connected with the rear automatic detacher.

Description

technical field [0001] The invention relates to the installation technology of a wind power generator set, more specifically, it relates to a single-blade hoisting tool and a hoisting method of a wind power generator set. Background technique [0002] The wind turbine system mainly includes three parts: the nacelle system, the wind turbine system, and the tower system. Due to the large structural size of the megawatt wind turbine system, the installation of the wind turbine system needs to be completed on the project site. The installation methods of the wind turbine system can generally be divided into two categories, one is integrated installation, that is, all blades and hub assemblies are assembled on the ground and hoisted as a whole; the other is to complete the hoisting of the hub assembly first, and then the blades The assembly with the wind wheel assembly is completed sequentially in the air in the way of single blade installation. [0003] With the strengthening o...
