Description

Technical Field

[0001] The utility model relates to the technical field of wind power blade production, in particular to a heating device for a modular blade box tooling. Background Art

[0002] Traditional wind turbine blades are often huge in size, and the transportation and installation process is complicated and costly. The design of modular wind turbine blades can break down the blades into smaller modules, which can be assembled on site after arriving at the installation site. In addition, modular wind turbine blades can be flexibly configured according to actual wind conditions and terrain conditions. Different modules can be combined into blades of different lengths and shapes to adapt to different wind resources and environmental conditions.

[0003] When modular wind turbine blades are assembled, the bonding strength at the interfaces of each module is the key to ensuring the integrity and safety of the entire blade structure. If the bonding strength is insufficient, it may cause cracks or breakages in the blade during operation, thus affecting the overall performance and safety of the wind turbine equipment. Usually, hot air is blown to the adhesive for heating, but hot air heating can easily cause the adhesive surface to dry too quickly while the inside is not fully heated. This temperature difference between the inside and outside may cause internal stress in the adhesive during the bonding process, affecting the bonding effect.

[0004] In order to solve the above problems, a heating device for modular blade box tooling is designed.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figures 1 to 4 As shown, a heating device for a modular blade box tooling comprises:

[0036] The positioning bracket 1 is provided with a plurality of horizontal bars 11 and vertical bars 12, and the positioning bracket 1 is provided with three parts, namely a front end bracket 13, a middle end bracket 14 and a rear end bracket 15;

[0037] The box-type tooling 2 is arranged on the positioning bracket 1, and the box-type tooling 2 is arranged in three parts, and is arranged corresponding to the front bracket 13, the middle bracket 14 and the rear bracket 15;

[0038] A heating blanket 3 is provided on the bottom surface of the internal interface of the box-shaped tooling 2, and the heating blanket 3 adopts an infrared radiation heating method;

[0039] Adhesive 21 is evenly applied around the inner interface of the box-shaped tooling 2.

[0040] By designing the positioning bracket 1 and the box-type tooling 2 as three parts, namely the front end, the middle end and the rear end, the entire device is more convenient to assemble and disassemble, which greatly reduces the difficulty of installation and maintenance. At the same time, the modular structural design also makes the connection between the various parts closer, thereby improving the stability and reliability of the overall structure. The heating blanket 3 adopts infrared radiation heating, which has fast infrared radiation heating speed, uniform heat distribution, energy saving and environmental protection. Infrared radiation can directly act on the adhesive 21, reduce heat loss in the air, improve heating efficiency, and infrared radiation heating also has good penetrability, thereby achieving more thorough heating.

[0041] In this embodiment, a plurality of positioning pillars 16 are fixedly disposed on one side of the positioning bracket 1, and two adjustment plates 16A and a suction cup 16B are disposed on the positioning pillars 16;

[0042] Wherein, the suction cup 16B is arranged between the two adjustment plates 16A;

[0043] The two adjustment plates 16A support the outer side surface of the box-shaped tooling 2 , and the suction cup 16B sucks the outer side surface of the box-shaped tooling 2 .

[0044] The support of the adjustment plate 16A and the adsorption effect of the suction cup 16B can ensure that the box-type tooling 2 is firmly fixed on the positioning bracket 1, thereby ensuring the stability of the box-type tooling 2 during the heating process; the design of the adjustment plate 16A can flexibly adapt to the sizes and shapes of different box-type tooling 2, and by adjusting the position and angle of the adjustment plate 16A, precise support for the outer side of the box-type tooling 2 can be achieved; the design of the suction cup 16B further strengthens the connection between the box-type tooling 2 and the positioning bracket 1, effectively preventing it from falling off or displacing.

[0045] In this embodiment, a plurality of tightening cylinders 17 are fixedly arranged on the other side of the positioning bracket 1, and a heating plate 17A is arranged on the tightening cylinder 17;

[0046] The pressing cylinder 17 drives the heating plate 17A to move in the horizontal direction, and the heating plate 17A presses the other outer side surface of the box-shaped tooling 2 and heats it.

[0047] By controlling the action of the tightening cylinder 17, the position and the clamping force of the heating plate 17A can be precisely adjusted, making the movement and control of the heating plate 17A more automated and precise; the heating plate 17A is in close contact with the other outer side surface of the box-type tooling 2, ensuring good heat conduction between the heating plate 17A and the box-type tooling 2, so that the heat is evenly distributed on the surface of the box-type tooling 2, reducing the influence of thermal expansion and contraction generated when the heating blanket 3 is heated.

[0048] In this embodiment, a docking slide rail 14A is provided at the bottom of the front bracket 13 and the rear bracket 15;

[0049] The setting position of the docking slide rail 14A corresponds to the position of the middle end bracket 14.

[0050] The docking slide rail 14A allows the front end bracket 13 and the rear end bracket 15 to be easily aligned and slid into each other during assembly, forming an overall stable positioning bracket 1. When disassembly is required, the slide rail can also be used to smoothly separate the various parts, simplifying the assembly and disassembly process; the docking slide rail 14A can ensure the accuracy of the positions of the front end bracket 13, the middle bracket 14 and the rear end bracket 15, and ensure the bonding effect of the box-type tooling 2.

[0051] In this embodiment, the positioning bracket 1 is provided with a plurality of bottom support plates along the length direction, and the shape of the bottom support plates is consistent with the bottom shape of the box-type tooling 2 .

[0052] Since the shape of the bottom support plate is consistent with the bottom shape of the box-type tooling 2, the bottom support plate and the box-type tooling 2 can fit tightly together, thereby providing uniform support force for the bottom of the box-type tooling 2 and ensuring the stability of the overall device. The presence of the bottom support plate can also protect the bottom of the box-type tooling 2 to a certain extent and can disperse the force on the bottom of the box-type tooling 2 during the heating process.

[0053] In this embodiment, a plurality of clamping cylinders 18 are provided near the interface of the box-type tooling 2 at the positioning bracket 1, and a pressing plate 18 is fixedly provided at one end of the clamping cylinder 18;

[0054] The shape of the pressing plate 18 is consistent with the top shape of the box-type tooling 2, and the pressing plate 18 can be rotated and lifted.

[0055] The clamping cylinder 18 can drive the pressing plate 18 to press the top of the box-type tooling 2 to ensure the compactness between the box-type tooling 2 and the positioning bracket 1. The shape of the pressing plate 18 is designed to be consistent with the top shape of the box-type tooling 2, which means that the pressing plate 18 can fit tightly to the top surface of the box-type tooling 2 and provide uniform clamping force, making the use of the device more stable, efficient and safe.

[0056] As a preference of the above embodiment, a temperature sensor 31 is provided on the heating blanket 3, and the temperature sensor 31 is connected to the control system for real-time monitoring of the temperature of the heating blanket 3 and automatically adjusting the temperature according to a preset temperature range.

[0057] The temperature of the heating blanket 3 is monitored in real time through the temperature sensor 31 to ensure the temperature control accuracy during the heating process. The real-time monitoring function allows the control system to provide real-time feedback and adjustment on the temperature of the heating blanket 3, thereby ensuring the stability and reliability of the heating process; the control system can automatically adjust the heating blanket 3 according to a preset temperature range. When the temperature of the heating blanket 3 exceeds or falls below the preset range, the control system will automatically adjust the heating power to maintain the temperature within an appropriate range. The automatic adjustment function not only ensures the consistency of the heating effect, but also avoids energy waste and improves the heating efficiency. Due to the precise control of the temperature sensor 31 and the control system, the temperature of the heating blanket 3 can remain stable and uniform, which helps to ensure the bonding effect of the box-type tooling 2.

[0058] As a preferred embodiment of the above, the positioning bracket 1 is provided with a probe bracket 19 near the interface, and the probe bracket 19 is provided with an optical meter seat 19A;

[0059] A cursor scale 19B is provided on the side of the box-shaped tooling 2, and the optical meter base 19A can detect the position of the cursor scale 19B.

[0060] The optical meter stand 19A can accurately detect the position of the cursor scale 19B on the side of the box-type tooling 2, thereby realizing precise positioning of the box-type tooling 2. This positioning method is more accurate than traditional mechanical positioning, and can greatly improve the reliability of the docking of the various parts of the box-type tooling 2; and through the method of detecting the cursor scale 19B by the optical meter stand 19A, the operator can intuitively understand the positioning and docking status of the box-type tooling 2 without the need for complex measurements and adjustments, which simplifies the operation process, reduces the difficulty of operation, and improves work efficiency.

The above embodiments and the description are only for explaining the principle of the present invention.
