Description
Technical Field
[0001] This utility model relates to the field of blade repair technology, and in particular to a blade repair fixture. Background Technology
[0002] Blade repair refers to the professional technical process of inspecting, maintaining, and repairing damaged or aging blades to restore their original performance, structural integrity, and safety. Blade repair fixtures are specialized tools or devices designed specifically for blades, used to precisely fix, position, and support specific areas of damaged blades, such as aircraft propellers, helicopter rotors, wind turbine blades, and ship propellers, during repair and maintenance.
[0003] Existing technologies also involve using ordinary mechanical clamps in conjunction with external heat sources, such as hot air guns or heating blankets, to fix the damaged blade area with simple clamps such as C-clamps and bolts, and then using independent heating equipment for heating and curing. This method uses dedicated clamps with low integration. Although dedicated clamps exist, their functions are limited, lacking intelligent control and safety guarantees. Moreover, traditional repair equipment is complex to operate and inconvenient to carry. For example, large ovens, bulky heating blanket power supplies, and multiple sets of separate clamps and tools result in a large overall weight and volume, requiring dedicated transport vehicles. This makes it difficult to quickly deploy and operate in outdoor environments such as high altitudes, offshore, and remote wind farms. On the other hand, the heat preservation time required by the heating equipment is also needed to ensure that the glue is completely cured, increasing ineffective working time. Therefore, the inventors have proposed a blade repair clamp to solve the above-mentioned technical problems. Utility Model Content
[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.
[0005] A blade repair fixture includes a heating control box and a fixing fixture box. The heating control box contains an integrated control box, and the fixing fixture box contains a fixture assembly. The fixture assembly includes a jaw, a clamping block, and a mounting base. The jaw is divided into an upper jaw and a lower jaw, which are connected by a ratchet structure. The clamping block is located at one end of the jaw and is arranged opposite to each other. The surface of the mounting base is connected to a heating component for heating and assisting blade repair. The integrated control box features both automatic and manual temperature control modes. It uses a high-precision digital display temperature controller, allowing for automatic temperature control via a set temperature, or manual temperature adjustment via increase / decrease buttons. The equipment includes integrated clamping components within a fixed clamping box, containing three sets of clamping assemblies. These assemblies can be detached from the fixed clamping box to form individual components. Each clamp includes a jaw with a ratchet mechanism 7, a clamping block, and a mounting base. The clamping mechanism enables rapid clamping, and the jaw has a ratchet retaining function. The jaw and clamping block hold the blade sheath to be repaired, and air is introduced via an inflatable bladder. The pressure gauge displays the current clamping pressure value and is connected to the integrated control box. It outputs an overpressure alarm when the pressure exceeds or falls below the set pressure during operation. The contact parts between the clamp and the blade are made of high-temperature resistant soft silicone material, which can withstand temperatures of 250℃ to 350℃. When the equipment is being repaired, the heating component can be adjusted to the set temperature based on the actual temperature, so that the blade repair area can maintain a relatively constant temperature. It has over-temperature protection and system fault alarm functions at the set temperature. It is controlled and detected by a PLC system and outputs audible and visual warnings of the working status. The clamp size allows for the repair of large-area blade delamination, with a clamping area of approximately 100cm² (18cm×8cm). The equipment consists of a heating control box and a fixed clamp box, both of which are hand-held for easy and quick movement. The fixed clamp box measures 59×40×29cm and contains clamps for holding the blades and a silicone heating plate. The heating control box measures 59×40×29cm and includes a display screen, PLC controller, audible and visual alarm, connecting cables, a foot pump, air hose, and other accessories. It adopts a plug-and-play, instant-heating method, and can quickly enter working condition after being powered on. The grippers and clamping blocks are designed for quick replacement, and the equipment is in a stopped state when disassembling or replacing them, thus preventing damage to the main blade. This structure adopts an integrated operation, improving upon traditional repair methods. Traditional repairs require first fixing the material with clamps and then heating it with external heat sources, such as hot air guns or heating blankets. This process is cumbersome and results in uneven heating. This design integrates the heating function directly into the clamps, achieving a highly efficient "clamp and heat" process. This improves repair efficiency, eliminates the time spent switching tools and repositioning, and significantly shortens the repair cycle. The clamps have a large contact surface with the blades and a high degree of fit. By designing to match the blade curvature, heat can be evenly distributed in the repair area, avoiding problems such as localized overheating leading to material performance degradation or insufficient heating leading to incomplete curing of the repair material.
[0006] Furthermore, the heating assembly includes a heating plate and an airbag. One end of the heating plate abuts against the surface of the mounting base, and the airbag is located between the heating plate and the mounting base. One end of the gripper is a pressure testing connector for connecting to an external power source. The pressure testing connector is connected to a power supply terminal, and one end of the pressure testing connector is a wire. One end of the wire extends to the surface of the heating plate. The heating plate has a thermal sensor and a temperature control module. The airbag achieves flexible fit and uniform pressure transmission. After inflation, the airbag is elastic and can conform to the curvature of the blades, pushing the heating plate to fit evenly against the area to be repaired, eliminating gaps, ensuring efficient heat conduction, and applying uniform pressure. By controlling the air pressure of the airbag, the heating plate can be evenly pressured onto the repair area. The pressure can be adjusted by an external air source. The gripper is mainly made of AL7075 aluminum alloy with a hard anodized surface and a ratchet locking mechanism. The clamping block is made of silicone and is installed on the gripper. The airbag is made of silicone and is injection molded in one piece. The inflation pressure can reach 0.6Mpa. When inflated, it is flexible and malleable, and can apply pressure evenly to the entire blade without causing damage. The mounting base is made of titanium alloy. The airbag is located inside the mounting base and acts on the clamps. The heating plate is a silicone heating plate with a current of 24V 160W. The main materials are silicone substrate and nickel-chromium alloy heating wire. The unfolded size is 355mm x 190mm. The heating plate is locked on the mounting base in the middle of the clamps and is in free contact with the airbag.
[0007] Furthermore, one end of the gripper is connected to an inflation connector, one end of which extends to the surface of the airbag. A limiting plate for auxiliary position definition is connected between the upper and lower grippers, with both ends of the limiting plate fixed to the surfaces of the grippers and the lower gripper, respectively. The inflation connector provides an independent air source channel for the airbag, enabling independent inflation and deflation of the airbag. The inflation connector is a connection channel between the airbag and an external air source such as an air pump or air tank, so as to control the inflation pressure of the airbag and adjust the pressure applied to the blade repair area. After the repair is completed, the airbag can be quickly deflated through this connector, causing it to contract and facilitating the disassembly of the clamp.
[0008] Furthermore, the surface of the integrated control box is equipped with operation buttons and a display screen, and the interior of the heating control box contains an alarm for auxiliary alarm warning. The integrated control box measures 59×40×29cm. It contains an electrical control system, an audible and visual alarm, connecting cables, a foot pump, and air hoses. The electrical control system, controlled by a PLC controller, manages heating temperature, heating timer, and pressure monitoring. Equipped with a temperature controller and pressure sensor, it monitors temperature and airbag pressure in real time. Abnormal temperatures and pressures are displayed on the touchscreen, and an audible and visual alarm is triggered. The integrated control box includes a leakage protection switch and fuse, providing overload and leakage protection. It features a touchscreen display, three temperature controllers, three pressure sensors, and three operating buttons: three aviation connectors for the heating plate, three pressure monitoring connectors, three heating start buttons, one aviation connector for the main power input, and one main switch button. The box also contains one circuit breaker and one fuse.
[0009] Furthermore, the fixed clamp box has an internal base plate for placing the clamp components. The fixed clamp box, clamp components, and base plate are detachable. Blade repair is often carried out in the field, hangar, dock, or at the bottom of the wind turbine tower, where space is limited and transportation is inconvenient. Separating the bulky fixed clamp box and base plate from the relatively smaller clamp components allows for separate packaging and transportation. The fixed clamp box, as a "base," can be placed at the work site for a long time, while the clamp components can be carried by technicians, reducing the weight and volume of each handling and improving mobility.
[0010] Furthermore, the upper and lower grippers are used to hold the blades; this is the most fundamental function of this structure. This design directly realizes the positioning, fixing, and force transmission of the clamp, providing stability for all subsequent operations such as heating, pressurizing, and repair. The following is the specific clamping process: 1. Open the ratchet lock of the clamp (ratchet structure), open the clamp and place it on the part of the blade that needs to be repaired, then lock the ratchet and clamp the jaws to fix the clamp on the blade; 2. After the clamp is fixed, connect the heating plate cable to the heating aviation plug on the control panel; 3. Open the valve on one side of the airbag's air tube connector and connect it to the corresponding inflation connector on the control panel; 4. Connect the foot pump's air hose to the air hose connector on the other side of the airbag and open the valve; 5. Remove the audible and visual alarm from the box and place it in a suitable position on the box or paddle. 6. Press the main switch on the control panel; the button indicator light will illuminate, and the electrical control system will start. 7. Set the heating temperature and time, and set the airbag pressure; 8. Step on the air pump. The air bag will start to inflate and flatten the heating plate and iron sheet to fit the blade. The pressure gauge on the control panel and the pressure gauge on the air pump will display the current pressure synchronously. Stop pumping when the set pressure is reached, close the valve at the inflation connector and pull out the air pump hose. 9. Press the corresponding heating switch button, the button light will turn on, and heating will begin. When the temperature reaches the set value, a countdown will begin. 10. Once the set heating time is reached, the system will automatically stop heating, and the alarm will sound and the lights will flash as a reminder. 11. Open the valve at the inflation connector to depressurize the airbag; 12. Disconnect the aviation plug for the heating plate on the panel and the airbag pressure hose; 13. Loosen the ratchet lock, remove the clamp, and the process is complete.
[0011] The following are the specific steps for structural distribution: 1. Clamping and positioning; The ratchet mechanism and clamping assembly quickly secure the entire clamp to the blade cladding repair area. The airbag is inflated and pressurized to between 0.3 and 0.5 MPa to apply pressure evenly to the sheet metal and adhere it to the composite material. The pressure gauge monitors the pressure in real time and provides an alarm effect in case of ultra-low pressure or high pressure. 2. Heat curing; Set the target temperature, such as 90℃, and the heating plate heats up at a rate higher than 16.7℃ / min. The PT100 sensor monitors in real time, and the PLC dynamically adjusts the power to maintain a constant temperature within ±5℃. 3. Repair complete; Four hours later, the adhesive was fully cured, the system indicated completion and issued an audible and visual alarm, released the airbag pressure, removed the clamp, and restored the propeller blades to combat readiness. 4. Safety protection; ① Over-temperature protection: When the temperature exceeds the set value by 10°C, the power will be cut off and an audible and visual alarm will be issued; ② Clamping force protection: An audible and visual alarm is triggered when the airbag pressure deviates from the set pressure by ±0.1 MPa; ③ Fault detection: An error message will be displayed if the temperature difference deviates by more than ±5℃ or the air pressure deviates by more than ±0.1Mpa; ④ Overload and leakage protection: dual protection of circuit breaker and fuse.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Total weight of the equipment: The overall weight without the bracket is 46KG, making it easy to carry and transport; 2. Select a suitable adhesive, which has been tested and confirmed to cure within 4 hours, thus improving repair time; 3. Working power supply: 220Vac / 50Hz, clamping area is 18cm×8cm, the equipment can work continuously for more than 5 hours after each power outage, and can maintain a long continuous working time. 4. The high-precision digital display temperature controller uses dual-chip temperature control, accurately sensing changes of 0.1℃, and precisely controlling the temperature. Once the set temperature is reached, it will automatically cut off the power to stop heating, ensuring that the temperature range of the repair area is ±5℃. 5. The high-precision digital display temperature controller has over-temperature protection and system fault alarm functions at the set temperature. When the temperature exceeds the set value, it will automatically cut off the power, stop heating, issue an alarm signal, and display the alarm content. 6. The clamps and blade holding and fixing parts are made of silicone, and the contact parts are made of high temperature resistant soft silicone.
[0013] 7. The digital display temperature controller has the function of setting upper and lower temperature limits, the constant temperature adjustment range is 0-150℃, and the maximum temperature rise rate is higher than 16.7℃ / min. Attached Figure Description

Detailed Implementation
[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] For this embodiment, please refer to Figures 1-9 The blade repair fixture specifically implemented therein includes a heating control box 1 and a fixing fixture box 2. The heating control box 1 contains an integrated control box 3, and the fixing fixture box 2 contains a fixture assembly. The fixture assembly includes a jaw 4, a clamping block 5, and a mounting base 6. The jaw 4 is divided into an upper jaw and a lower jaw, which are connected by a ratchet structure 7. The clamping block 5 is located at one end of the jaw 4 and is arranged opposite to each other. The surface of the mounting base 6 is connected to a heating component for heating and assisting the blade repair. The integrated control box 3 features both automatic and manual temperature control modes. It uses a high-precision digital display temperature controller, allowing for automatic temperature control via a set temperature, or manual adjustment via increase / decrease buttons. The device includes integrated clamping components in the fixed clamping box 2, containing three sets of clamping assemblies. These assemblies can be detached from the fixed clamping box 2 to form individual components. Each clamp includes a jaw 4 with a ratchet mechanism 7, a clamping block 5, and a mounting base 6. The clamping mechanism enables rapid clamping. The jaw 4 has a ratchet retaining function. The jaw 4 and clamping block 5 clamp the blade sheath to be repaired, using an airbag. 9. Inflate and pressurize. The pressure gauge displays the current clamping pressure value and is connected to the integrated control box 3. When the pressure exceeds or falls below the set pressure during operation, an overpressure alarm is output. The contact part between the clamping block 5 and the blade is made of high-temperature resistant soft silicone material, which can withstand high temperatures of 250℃-350℃. When the equipment is being repaired, the heating component can be adjusted to the set temperature based on the actual temperature, so that the blade repair area can maintain a relatively constant temperature. It has over-temperature protection and system fault alarm functions at the set temperature. It is controlled and detected by a PLC system and outputs audible and visual warnings of the working status. The clamp size allows for the repair of large-area blade delamination, with a clamping area of approximately 100cm² (18cm×8cm). The equipment consists of a heating control box 1 and a fixed clamp box 2, both of which are hand-held for easy and quick movement. The fixed clamp box 2 measures 59×40×29cm and contains clamps for holding the blades and a silicone heating plate. The heating control box 1 measures 59×40×29cm. The integrated control box 3 contains a display screen, PLC controller, audible and visual alarm, connecting cables, a foot pump, air hoses, and other accessories (not shown). It adopts a plug-and-play heating method, and can quickly enter the working state after being powered on. The grippers 4 and clamping blocks 5 are designed for quick replacement. When disassembling and replacing them, the equipment is in a stopped state, which does not cause damage to the main blades. This structure adopts an integrated operation, improving the traditional repair method. Traditional repair requires fixing with clamps first, and then heating with external heat sources, such as hot air guns or heating blankets. The steps are cumbersome and the heating is uneven. This design integrates the heating function directly into the clamps, realizing a highly efficient process of "clamping and heating", improving repair efficiency, saving the time of switching tools and repositioning, and significantly shortening the repair cycle. The clamp block 5 has a large contact surface with the blade and a high degree of fit. By matching the curvature of the blades, the heat can be evenly distributed in the repair area, avoiding the problems of local overheating leading to material performance degradation or insufficient heating leading to incomplete curing of the repair material.
[0017] The heating assembly includes a heating plate 8 and an airbag 9. One end of the heating plate 8 abuts against the surface of the mounting base 6. The airbag 9 is located between the heating plate 8 and the mounting base 6. One end of the gripper 4 is a pressure testing connector 10 for connecting to an external power source. The pressure testing connector 10 is connected to a power supply terminal 11. One end of the pressure testing connector 10 is a wire, and the other end of the wire extends to the surface of the heating plate 8. The heating plate 8 has a thermal sensor and a temperature control module (not shown). The airbag 9 achieves flexible fitting and uniform pressure transmission. After inflation, the airbag 9 is elastic and can conform to the curvature of the blades, pushing the heating plate 8 to fit evenly against the area to be repaired, eliminating gaps, ensuring efficient heat conduction, and applying uniform pressure. By controlling the air pressure of the airbag 9, the heating plate 8 can be evenly pressured onto the repair area. The pressure can be adjusted by an external air source. The gripper 4 is mainly made of AL7075 aluminum alloy with a hard anodized surface and a ratchet locking mechanism. The clamping block 5 is made of silicone and is installed on the gripper 4. The airbag 9 is made of silicone and is integrally injection molded. The inflation pressure can reach 0.6Mpa. When inflated, it has flexibility and plasticity, and can apply pressure evenly to the entire blade without causing damage. Mounting base 6 is made of titanium alloy. Airbag 9 is located inside mounting base 6 and acts on clamps. Heating plate 8 is a silicone heating plate, using 24V 160W current. The main materials are silicone substrate and nickel-chromium alloy heating wire. The unfolded size is 355mm x 190mm. Heating plate 8 is locked on mounting base 6 in the middle of clamp 4 and is in free contact with airbag 9.
[0018] One end of the gripper 4 is connected to an inflation connector 12, one end of which extends to the surface of the airbag 9. A limiting plate 13 for auxiliary position definition is connected between the upper and lower grippers. The two ends of the limiting plate 13 are fixed to the surfaces of the gripper and the lower gripper, respectively. The inflation connector 12 provides an independent air source channel for the airbag 9, enabling independent inflation and deflation of the airbag. The inflation connector 12 is a connection channel between the airbag 9 and an external air source such as an air pump or air tank, so as to control the inflation pressure of the airbag 9 and adjust the pressure applied to the blade repair area. After the repair is completed, the airbag 9 can be quickly deflated through this connector, making it easier to disassemble the clamp.
[0019] The integrated control box 3 is equipped with operation buttons 14 and a display screen 15 on its surface. The heating control box 1 contains an alarm 16 for auxiliary alarm warning. The integrated control box 3 measures 59×40×29cm and contains an electrical control system, an audible and visual alarm, connecting cables, a foot pump, air hoses, and other accessories. The electrical control system mainly controls the heating temperature, heating time, and pressure monitoring. It is controlled by a PLC controller and equipped with a temperature controller and a pressure sensor. It can monitor the temperature and airbag pressure in real time. When the temperature and pressure are abnormal, the touch screen displays the abnormal content and the alarm 16 emits an audible and visual alarm. The integrated control box 3 is equipped with a leakage protection switch and a fuse, and has overload and leakage protection functions. The display screen 15 is a touch screen. There are 3 sets of temperature controllers and 3 sets of pressure sensors. The operation buttons 14 include 3 heating plate aviation plugs, 3 pressure monitoring connectors, 3 heating start buttons, 1 main power input aviation plug, and 1 main switch button. The box contains 1 circuit breaker and 1 fuse.
[0020] The fixed clamp box 2 has a base plate 17 for placing the clamp components inside. The fixed clamp box, clamp components and base plate 17 are detachable. Blade repair is often carried out in the field, hangar, dock or at the bottom of wind turbine tower. Space is limited and transportation is inconvenient. Separating the bulky fixed clamp box 2 and base plate 17 from the relatively small clamp components allows for separate packaging and transportation. The fixed clamp box 2 can be placed at the work site for a long time as a "base", while the clamp components can be carried by technicians, reducing the weight and volume of each handling and improving mobility.
[0021] The upper and lower jaws are used to clamp the blade 18; this is the most fundamental function of this structure. This design directly realizes the positioning, fixing and force transmission of the clamp, providing stability for all subsequent operations such as heating, pressurizing, and repair. The following is the specific clamping process: 1.

[0022] The following are the specific steps for structural distribution: 1. Clamping and positioning; The ratchet mechanism and clamping assembly quickly secure the entire clamp to the 18 iron-clad repair area of the propeller blade. The airbag 9 is inflated and pressurized to between 0.3 and 0.5 MPa to apply pressure evenly to the sheet metal and adhere it to the composite material.
