Description

Technical Field

[0001] The utility model relates to the technical field of wind power blade hoisting rigging, and more specifically to a hoisting rigging used for a wind power installation crane. Background Art

[0002] Wind turbine blades are the core components of wind turbines. Their main function is to convert natural wind energy into electrical energy. They are responsible for capturing wind energy and converting it into mechanical energy, which is then converted into electrical energy through generators.

[0003] Crane lifting rigging is needed for the installation and processing of wind turbine blades on the market. The rigging lifts the wind turbine blades and performs drilling positioning or installation coordination on the blades. However, the existing crane lifting rigging usually lifts the wind turbine blades from the middle. When drilling holes, the blades are suspended in the air, with extremely poor stability, swaying, and easy to shake, which will undoubtedly cause great obstacles to the drilling positioning or installation process, and will also significantly increase the difficulties caused by the lifting and transportation process.

[0004] Based on the above background, a lifting rigging for a wind power installation crane is proposed to solve the problem. Summary of the invention

[0005] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0006] The utility model aims to overcome the above-mentioned shortcomings and provide a hoisting rigging for a wind power installation crane.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a lifting rigging for a wind power installation crane, including: a balance seat, a lifting ring, a hook, a chain, a hook, a cylinder, and a hanging plate, wherein a plurality of lifting rings are provided and are symmetrically arranged on the balance seat; the lifting hook is buckled on the lifting ring; the chain is connected to the lifting hook; the hook is connected to the chain; a plurality of cylinders are provided and are symmetrically arranged under the balance seat; and the hanging plate is connected to the rod body of the cylinder.

[0008] Preferably, the hanging plate adopts a right-angle plate structure.

[0009] Preferably, the vertical plate on the hanging plate is connected to the rod body of the cylinder, and the horizontal plate is used to support and lift the wind turbine blades.

[0010] Preferably, a slide rail is provided on the hanging plate.

[0011] Preferably, a lifting plate is installed on the hanging plate and is connected to the slide rail.

[0012] Preferably, a rubber anti-wear pad is attached to the lifting plate.

[0013] Preferably, a first bolt is connected to the lower side of the hanging plate, and the first bolt is threaded through the bottom of the hanging plate and abuts against the lower side of the lifting plate.

[0014] Preferably, a plurality of second bolts are threadedly connected to the lower side of the balancing seat and are used to fix the cylinder on the balancing seat.

[0015] The beneficial effects of the utility model are as follows: when lifting the wind turbine blades, the utility model controls the movement of the hanging plate through the rod body of the cylinder, so that the hanging plate can scoop up all the blades of the wind turbine. When the crane is lifted again, the hanging plate lifts the wind turbine blades. During the lifting process, the wind turbine blades are supported by the hanging plate, which has the effect of making the wind turbine blades more stable in the air and easier to install and process. Moreover, when lifting and transporting, the suspension of the wind turbine blades is more balanced, and the transportation will be more stable and safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a lifting rigging for a wind power installation crane, comprising: a balance seat 1, a lifting ring 2, a hook 3, a chain 4, a hook 5, a cylinder 6, and a hanging plate 7. The lifting ring 2 is provided in plurality and is symmetrically arranged on the balance seat 1; the hook 3 is buckled on the lifting ring 2; the chain 4 is connected to the hook 3; the hook 5 is connected to the chain 4; the cylinder 6 is provided in plurality and is symmetrically arranged under the balance seat 1; the hanging plate 7 is connected to the rod body of the cylinder 6.

[0024] When in use, the rigging is installed on the crane through the hook 5. When the wind turbine blade needs to be lifted, the crane lowers the height of the balance seat 1 so that the hanging plate 7 is level with the wind turbine blade. Then the rod of the cylinder 6 retracts and moves the hanging plate 7 toward the balance seat 1. There are several hanging plates 7, and the hanging plates 7 can scoop up all the blades of the wind turbine. When the crane is lifted again, it drives the hanging plates 7 to lift the wind turbine blades. During the lifting process, the wind turbine blades are supported by the hanging plates 7, which makes the wind turbine blades more stable in the air and easier to install and process.

[0025] According to some embodiments of the present application, the hanging plate 7 is optionally a right-angle plate structure, the vertical plate on the hanging plate 7 is connected to the rod body of the cylinder 6, and the horizontal plate is used to support the wind turbine blades.

[0026] According to some embodiments of the present application, optionally, a slide rail 8 is provided on the hanging plate 7, a lifting plate 9 is installed on the hanging plate 7 and connected to the slide rail 8, and a first bolt 10 is connected to the lower side of the hanging plate 7, and the first bolt 10 is threaded through the bottom of the hanging plate 7 and abuts against the lower side of the lifting plate 9. In order to make the wind turbine blade more stable on the hanging plate 7, by rotating the first bolt 10, the first bolt 10 is screwed upward against the lifting plate 9, and the lifting plate 9 moves upward under the action of the slide rail 8, and the wind turbine blade is supported to move upward until it is clamped between the rod body of the cylinder 6, so that not only wind turbine blades of different thicknesses can be supported, but also they can be clamped, so that they are not easily offset by processing and installation on the hanging plate 7, and effectively prevent them from separating from the hanging plate 7 and falling, causing unnecessary installation accidents.

[0027] According to some embodiments of the present application, optionally, a rubber anti-wear pad is attached to the lifting plate 9. The rubber anti-wear pad has the function of preventing a large wear on the surface of the wind turbine blade and protecting it.

[0028] According to some embodiments of the present application, optionally, a plurality of second bolts 11 are threadedly connected to the lower side of the balancing seat 1 and are used to fix the cylinder 6 on the balancing seat 1. By screwing the second bolts 11 upward, the second bolts 11 push the cylinder 6 against the balancing seat 1, thereby fixing and installing it. The operation is simple and easy to understand, and the installation is more convenient.
