Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade hoisting technology, and in particular to a wind-catching bracket for hoisting a single blade. Background Technology

[0002] As the component with the largest windward area among all turbine equipment, the blade assembly of a wind turbine (hereinafter referred to as "wind turbine") is highly susceptible to the influence of ambient wind speed during installation, making construction difficult. Therefore, the installation of a wind-guiding device is particularly important when hoisting the blade assembly to effectively ensure the safety of equipment and personnel. Currently, the commonly used wind-guiding device mainly utilizes several long guy ropes, with one end fixed to a key part of the blade and the other end anchored at a point. Multiple construction workers pull the ropes to maintain the stability of the blade assembly during the hoisting process.

[0003] The existing technology has the following problems: 1. Adjusting the direction of the blade assembly and controlling its angle requires occupying a large area of ​​land around the wind turbine, making the surrounding environment a limiting factor, increasing construction difficulty and temporary land acquisition costs; 2. The required length of guy ropes is relatively long, usually 0.4-0.5 times longer than the height of the wind turbine. The guy ropes themselves are also quite heavy, which greatly increases the manpower required.

[0004] 3. Controlling the equipment manually increases the cost of human resources. In the event of a sudden strong wind, it is extremely difficult to control the blade device manually, which can easily cause injury to construction workers and damage to the equipment. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art, such as the need to occupy a large area of ​​land around the wind turbine during the blade hoisting process, the need for long guy ropes, and the great difficulty of manually controlling the blade device. Therefore, a wind-catching bracket for single blade hoisting is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A single-blade hoisting wind-gathering bracket includes a support base and multiple clamps. A first support column is fixedly connected to one side of the support base, and a second support column is fixedly connected to one side of the first support column. An adjusting rod is fixedly connected to the end of the first support column away from the support base. An adjusting column is slidably sleeved on the adjusting rod, and a fixing structure is slidably inserted into the adjusting column. Multiple fixing holes corresponding to the adjusting structure are equidistantly provided on the adjusting rod. The second support column has a guide rod slidably inserted at the end away from the support base, and a connecting column is fixedly connected to one end of the guide rod. The connecting column and the adjusting column are fixedly connected by a reinforcing rod. A third support column is rotatably connected to the side of the support base away from the first and second support columns. The ends of the connecting column, adjusting column, and third support column away from the support base are respectively connected to multiple clamps through a connecting structure.

[0007] Preferably, the support base is provided with multiple fastening ports.

[0008] Preferably, the fixing structure includes a fixing rod, a limiting sleeve is fixedly sleeved at one end of the fixing rod near the adjusting rod, a pull rod is fixedly connected at the other end of the fixing rod away from the limiting sleeve, and a spring is sleeved on the fixing rod, with the two ends of the spring abutting against the pull rod and the adjusting column respectively.

[0009] Preferably, a limit block is fixedly connected to one end of the guide rod located inside the second support column.

[0010] Preferably, the connection structure includes a connecting block, on which a pin and a safety pin corresponding to the clamp are slidably inserted.

[0011] Preferably, a rubber pad is fixedly connected to the inner wall of the clamp.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The device in this invention uses small modular connection and installation, which makes assembly easy and can be flexibly assembled at various positions on the crane boom to adapt to the installation of wind turbine blades at different heights.

[0013] The device in this invention can be used in conjunction with a single-blade lifting tool to remotely control the blade deflection angle, reducing the difficulty of docking during blade installation and reducing the need for manpower.

[0014] The device in this invention can withstand greater tension from the blades, making it more advantageous in dealing with sudden environmental factors such as strong winds, and can more effectively protect the safety of personnel and equipment.

[0015] The device in this invention is directly installed on the crane boom, which greatly reduces the need for temporary land use during blade hoisting. It is suitable for various wind power environments such as onshore plains, mountains, and offshore, and reduces construction costs. Attached Figure Description
