Description

Technical Field

[0001] The utility model relates to the technical field of wind power operation, maintenance and detection, in particular to a fixed tool for wind power blade detection. Background Art

[0002] Wind turbine operation and maintenance (O&M) and inspection technology are crucial areas of wind farm management, encompassing routine turbine maintenance, troubleshooting, and performance optimization. Blades, as key components of wind turbines, have drawn significant attention for their inspection technology. Common inspection methods include infrared thermal imaging, ultrasound, and laser scanning, aiming to identify potential blade defects such as cracks, delamination, and corrosion. However, due to their large size and complex structure, blade inspection places high demands on both inspection equipment and auxiliary tools.

[0003] Fixed fixtures for wind turbine blade inspection have emerged as a necessary step, specifically designed to provide stable support during the inspection process. Through precise positioning and secure fixation, they ensure efficient and accurate inspections. Combined with intelligent equipment, they support automated and remote inspections. As a crucial component of wind turbine O&M, the use of fixed fixtures enhances the safety and reliability of blade inspections, safeguarding the stable operation of wind farms.

[0004] The wind turbine blade inspection fixture is a specialized device used to support and stabilize blades. It primarily consists of a base, support frame, clamping device, adjustable mechanism, and auxiliary function modules. The base and support frame provide stability, the clamping device secures the blade, and the adjustable mechanism allows for height and angle adjustments to accommodate various inspection requirements. The fixture's core function is to stabilize the blade, preventing inspection errors caused by vibration or movement and ensuring accuracy. As a crucial tool for wind farm operations and maintenance, the fixture not only ensures operational safety but also provides reliable support for accurate and efficient blade inspections.

[0005] The existing technology has the following deficiencies and defects in the design of wind turbine blade fixing tooling: First, the blade fixing method of traditional tooling usually relies on a simple clamping device or a rigid fixing structure, and lacks a flexible reinforcement mechanism. When the equipment is subjected to external vibration or impact during transportation or testing, the blades are prone to slip or loosening, which not only increases the risk of wear on the blade surface, but may also cause instability of the overall tooling. Secondly, in the contact area between the blade and the tooling, the existing design usually uses hard materials or a single contact surface, which can neither effectively reduce the friction between the blade and the placement block, nor absorb the vibration or shaking generated during the movement of the equipment. This deficiency makes the blades vulnerable to damage during transportation and operation, and also reduces the stability and safety of the tooling under complex working conditions.

[0006] In view of the above problems, a fixed tooling for wind turbine blade inspection is proposed to solve the above problems. Utility Model Content

[0007] In order to make up for the above deficiencies, the utility model provides a fixed tooling for wind turbine blade inspection, aiming to solve the problems of unstable fixation, easy sliding and damage caused by vibration of wind turbine blades during transportation.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a fixed tool for wind turbine blade detection, comprising two base plates and a fixed frame, wheels are installed on both sides of the bottom of the base plates, an operating box is installed on the top of one of the base plates, a lifting mechanism is provided on the top of the two base plates, an adjustment mechanism is provided on the inner side of the fixed frame, a connector is provided directly below the adjustment mechanism, both sides of the connector are connected to the connection frame by steel wire ropes, a placement block is fixedly connected to the bottom of the connection frame, a reinforcement mechanism is provided inside the placement block, and a protective component is provided on the top of the placement block;

[0011] The lifting mechanism comprises a support column, and a hydraulic rod is arranged on the outer side of the support column.

[0012] As a further description of the above technical solution:

[0013] The placement block is located right in the middle of the two bottom plates, and the placement block is located right below the connector.

[0014] As a further description of the above technical solution:

[0015] A force-bearing block is provided at a position of the fixing frame close to the lifting mechanism, and a plurality of reinforcement rods are vertically installed inside the fixing frame.

[0016] As a further description of the above technical solution:

[0017] The hydraulic rod is located between the bottom plate and the force-bearing block, and the support column is located between the bottom plate and the fixing frame.

[0018] As a further description of the above technical solution:

[0019] The adjustment mechanism includes two rope winding wheels, which are arranged inside the fixed frame. The rope winding wheels are connected to the winding roller through a steel wire rope. A motor is provided on the fixed frame, and the output end of the motor is fixedly connected to the inside of the winding roller.

[0020] As a further description of the above technical solution:

[0022] As a further description of the above technical solution:

[0023] The protection component includes a plurality of rubber pads, and a plurality of anti-slip balls are arranged between two of the rubber pads.

[0024] The utility model has the following beneficial effects:

[0025] 1. In the utility model, a reinforcement mechanism is provided inside the placement block, which is mainly composed of reinforcement pins, elastic straps or steel wire ropes, and adjustment blocks. A total of four reinforcement pins are symmetrically installed on both sides of the placement block. After the blades are placed, straps or steel wire ropes are used to form a cross fixation between the reinforcement pins. The adjustment block on the top of the placement block can change the tension and angle of the straps or steel wire ropes to enhance the restraint ability of the blades. This design effectively prevents the blades from sliding during transportation and avoids wear on the blade surface due to accidental movement. At the same time, the reinforcement mechanism enhances the stability of the overall tooling, ensuring that the blades can remain fixed even if they are subjected to external vibrations or impacts during transportation and operation.

[0026] 2. In this utility model, multiple rubber pads are evenly mounted on the curved surface of the placement block. These rubber pads offer flexible contact, effectively reducing friction and wear between the blades and the tooling. Furthermore, anti-slip balls are positioned between each pair of rubber pads. These flexible, point-like support balls further reduce direct contact between the blades and the placement block surface. This structure not only prevents damage to the blade surface caused by vibration during equipment movement, but also effectively absorbs stress caused by shaking, thereby improving stability during transportation and operation.

[0033] Reference Figure 1 - Figure 2 The present invention provides an embodiment of a fixed tool for wind turbine blade inspection, comprising two base plates 1 and a fixed frame 6. Wheels 2 are installed on both sides of the bottom of the base plate 1 to facilitate the flexible movement of the equipment in different inspection sites. An operating box 3 is installed on the top of one of the base plates 1. The operating box 3 integrates an electronic control system for controlling the lifting and reinforcement operations of the tool. A lifting mechanism 4 is provided on the top of each of the two base plates 1. The lifting mechanism 4 consists of a support column 401 and a hydraulic rod 402.

A plurality of reinforcement rods 7 are vertically installed inside the fixed frame 6 to enhance the strength and rigidity of the overall structure.

[0034] Reference Figure 1 - Figure 2, an adjustment mechanism 8 is provided on the inner side of the fixed frame 6, and the adjustment mechanism 8 consists of two rope-winding wheels 801, a winding roller 803 and a motor 802. The rope-winding wheel 801 is installed inside the fixed frame 6 and is connected to the winding roller 803 by a steel wire rope, and the winding roller 803 is driven to rotate by the motor 802. A connector 9 is provided directly below the adjustment mechanism 8, and the rope-winding wheel 801 is connected to the two sides of the connector 9 by steel wire ropes. The connector 9 is further connected to the two connecting frames 12 by steel cables. The bottom of the connecting frame 12 is fixedly connected to the placement block 11, and the placement block 11 is located in the middle of the two base plates 1 and directly below the connector 9. This design can drive the steel wire rope through the motor 802 to adjust the position and tension of the placement block 11, thereby achieving precise positioning and firm fixation of the blade, effectively adapting to the needs of different detection scenarios.
