Description

Technical Field

[0001] The utility model relates to the technical field of web demoulding, in particular to an electric mould lifting tool for the web of a wind turbine blade. Background Art

[0002] With the enlargement of wind turbines and blades, it is necessary to reduce the load and weight of the blades. Using a single I-shaped web on the main beam is an important measure to reduce the load and weight. To reduce the load, the main beam and the web are arranged at the front edge, resulting in the bonding surface of the web in some areas being inclined inward, which is not conducive to web demoulding. To make the auxiliary bonding part of the I-shaped web, it is necessary to set slots in advance on the web mould and fill them with silica gel to assist in the formation of the auxiliary bond, which further increases the difficulty of web mould lifting.

[0003] At present, there are two common methods for web mould lifting. One is to pry up the web at the root or tip of the web blade first, pass a sling through the lower part of the web, and hang it on the crane. Then, the web is demoulded by lifting with the crane, which is likely to cause defects such as extrusion damage, bruising, and large surface deformation. The other method is to place a steel pipe under the web, and two operators stand on both sides respectively and push the steel pipe forward to gradually separate the web from the mould. This operation causes sliding friction between the steel pipe and the I-shaped web, which is extremely likely to damage the auxiliary bonding part of the I-shaped web. Therefore, an electric mould lifting tool for the web of a wind turbine blade is proposed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an electric mould lifting tool for the web of a wind turbine blade, which solves the technical problems of easy extrusion damage, bruising, large surface deformation, etc. of the web during web mould lifting in the prior art.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] To enable those skilled in the art of this technology to better understand the solution of the present invention, the following will further elaborate on the present invention in conjunction with the drawings and specific embodiments.

[0027] As Figure 1 shown, to achieve the above object, the present invention provides a web electric mold lifting tooling for wind turbine blades, including: a tooling bottom plate 1, a bracket side plate 10, and a jacking mechanism 8.

[0028] The left end of the tooling bottom plate 1 is rotatably connected to the driving shaft 3, and the right end of the tooling bottom plate 1 is rotatably connected to the driven shaft 4. Specifically, the driving shaft 3 is arranged at the rear end of the tooling bottom plate 1, the driven shaft 4 is arranged at the front end of the tooling bottom plate 1, and both ends of the driving shaft 3 and both ends of the driven shaft 4 are respectively connected to wheels.

[0029] The driven shaft 4 is rotatably connected to the bracket side plate 10. Specifically, a first through hole is provided at one end of the bracket side plate 10. The first through hole is used to pass the driven shaft 4, and the driven shaft 4 is rotatably connected to the first through hole. The bracket side plate 10 is provided with a plurality of roller groups, which are arranged in an array along the length direction of the bracket side plate 10. The web is supported by the roller groups. The bracket side plate 10 has better stability than the sling structure. The web is further lifted by a plurality of roller groups. The web will not easily shake or tilt unbalanced, thus avoiding defects such as bumps, bruises, and large-surface deformation of the web, and at the same time improving the safety factor of production operations. Moreover, when the web demoulding tooling is pushed along the web mold, the roller group abuts against the surface of the web. When the web is gradually lifted from the web mold, the roller group can rotate relative to the bracket side plate 10, thereby forming rolling friction with the web, effectively avoiding damage to the auxiliary bonding part of the I-shaped web.

[0030] A bracket support plate 9 is provided at the right end portion of the bracket side plate 10. Preferably, the bracket support plate 9 is formed integrally with the bracket side plate 10 by bending, or the bracket support plate 9 can be connected to the bracket side plate 10 by welding. On the one hand, the bracket support plate 9 can assist in enhancing the overall structural strength of the bracket side plate 10 and improve the bearing capacity of the bracket side plate 10. On the other hand, the bracket support plate 9 provides a connection point for the top end of the jacking mechanism 8, so that the bracket side plate 10 can be stably connected to the jacking mechanism 8.

[0031] A jacking mechanism 8 is arranged on the top surface of the tooling base plate 1. Preferably, the jacking mechanism 8 is a hydraulic telescopic rod. The top end of the jacking mechanism 8 is slidably connected to the bracket support plate 9. The angle between the bottom surface of the bracket support plate 9 and the top surface of the tooling base plate 1 is adjusted by the jacking mechanism 8. The overall height of the demolding tooling is adjusted according to demand to be suitable for the demolding of different types of webs, thereby improving the versatility of the overall demolding tooling.

[0032] When in use, the demolding tool is placed under the web. According to the height required for demolding the web, the lifting mechanism 8 is extended to lift the bracket support plate 9 and make it close to the lower surface of the web. The multiple roller groups on the bracket side plate 10 further lift the web. The overall demolding tool is moved to gradually separate the web from the web mold. Compared with the traditional sling demolding method, the overall demolding tool eliminates the waiting time of the driving station and the time of the sling constantly shifting, effectively improving the production efficiency of the web. Multiple roller groups lift the web, and the web will not be damaged by the sling squeezing the web, which effectively improves the safety of the web during demolding.

[0033] like Figure 2 As shown, the roller assembly includes: a roller mounting shaft 13, both ends of the roller mounting shaft 13 are fixedly connected to the bracket side plate 10, and the outer peripheral side of the roller mounting shaft 13 is rotatably connected to the rotating roller 12, wherein each roller is fixed to the roller mounting shaft 13 by a ball assembly to ensure that the rotating roller 12 can rotate freely relative to the bracket side plate 10.

[0034] In addition, limiting springs 14 are provided at both ends of the rotating roller 12. The limiting springs 14 are arranged on the outer peripheral side of the roller mounting shaft 13. One end of the limiting spring 14 is rotatably connected to the support side plate 10. The limiting springs 14 provided at both ends of the rotating roller 12 have a certain pushing force on the rotating roller 12, thereby forming a certain axial limiting effect on the rotating roller 12, preventing the rotating roller 12 from moving back and forth relative to the support side plate 10, and further improving the stability when the roller group supports the web.

[0035] When installing the roller group onto the support side plate 10, select a suitable roller group according to requirements. Sleeve the rotating roller 12 on the outer peripheral side of the roller mounting shaft 13. The limiting springs 14 are arranged at both ends of the rotating roller 12. The roller mounting shaft 13 passes through the support side plate 10, and the installation of each roller group is completed in sequence. Preferably, thread lines are provided at both ends of the roller mounting shaft 13, and the two ends of the roller mounting shaft 13 are fixed by nuts. Of course, pin holes can also be provided at both ends of the roller mounting shaft 13, and the two ends of the roller mounting shaft 13 are fixed by split pins. The specific form of the fixed connection between the roller mounting shaft 13 and the support side plate 10 is not specifically limited, and the purpose is to stably fix the roller mounting shaft 13.

[0036] In an embodiment of the present utility model, a protective pad is provided on the outer peripheral side of the rotating roller 12. The protective pad is made of a flexible material. The flexible protective pad can prevent the rotating roller 12 from directly contacting the web rigidly, avoiding defects such as knocks, bumps, and surface deformation of the web, and playing a role in protecting the web. Preferably, the anti-slip pad is made of polyurethane material. Utilizing the functional characteristics of polyurethane material having certain elasticity and wear resistance, the protective pad has a longer service life. When the mold lifting tooling advances along the web mold, the roller group abuts against the web surface, forming a rolling friction with the web, and gradually lifting the web from the mold.

[0037] Of course, the material of the flexible material is not specifically limited, and the purpose is to prevent the rotating roller 12 from directly contacting the web rigidly and play a role in protecting the web.

[0038] A number of support struts 11 are arranged in an array on the support side plate 10. Both ends of the support struts 11 are fixedly connected to the support side plate 10. Specifically, the support struts 11 are evenly arranged on the inner side of the support side plate 10. Preferably, a support strut 11 is provided between every two adjacent roller groups. The support strut 11 is connected to the support side plate 10 by welding. The setting of the support strut 11 further improves the structural strength of the support side plate 10, avoids the deformation of the support side plate 10 during the mold lifting process, and enhances the strength and safety stability of the mold lifting tooling.

[0039] Among them, the support strut 11 of the support can adopt one or more structural forms of round tubes, square tubes, and steel bars, and the specific quantity is determined according to the length of the mold stripping tooling. It should be noted that the highest point of the support strut 11 is lower than the highest point of the roller group to avoid affecting the stable contact between the roller group and the bottom surface of the web.

[0040] A driving device 5 is provided on the top surface of the tooling base plate 1. Preferably, the driving device 5 is a three-phase asynchronous motor, which can switch the driving direction and can be equipped with a remote control system. The start and stop of the driving device 5 can be controlled through the remote control system, and at the same time, the driving device 5 can be controlled to drive the output end to rotate forward and backward, so as to control the forward and backward movement of the entire mold stripping tooling. The output end of the driving device 5 is connected to the driving shaft 3, and the driving device 5 drives the wheels to rotate, moving the entire mold stripping tooling, so that the web can be gradually separated from the web mold. Compared with the traditional manual-assisted mold stripping, the labor intensity of the operators is reduced, the waiting time at the overhead crane station and the time for the sling to continuously shift are eliminated, and the production efficiency of the web is effectively improved.

[0041] In an embodiment of the present utility model, the wheels are made of rubber. By utilizing the functional characteristics of rubber with a high friction coefficient and wear resistance, when the mold stripping tooling moves, it can play a certain anti-slip effect on the entire mold stripping tooling, maximize the conversion of the power output by the driving device 5, and provide a stable driving force for the entire mold stripping tooling.

[0042] In an embodiment of the present utility model, an auxiliary push rod tube 15 is provided on the support side plate 10. The two ends of the auxiliary push rod tube 15 are fixedly connected to the support side plate 10. On the one hand, the auxiliary push rod tube 15 can assist in enhancing the structural strength of the support side plate 10, thereby improving the stability during web support and enhancing the safety of the mold stripping tooling. On the other hand, the auxiliary push rod tube 15 is a steel tube structure with both ends communicating. A push rod with a diameter smaller than the smaller one can be inserted into its inner side, and both ends of the push rod extend out of the auxiliary push rod tube 15. When using the mold stripping tooling, when encountering a blockage and the driving device 5 lacks power or it is inconvenient to use the driving device 5, the steel tube can be passed through the through hole, and the mold stripping tooling can be assisted to move by pushing the steel tube. The operator can assist the movement of the mold stripping tooling by pushing the push rod.

[0043] In an embodiment of the present utility model, a plurality of wheel side plates 2 are symmetrically arranged on the tooling base plate 1. A second through hole for passing through the drive shaft 3 or the driven shaft 4 is provided on the side surface of the wheel side plate 2. Specifically, the second through hole on the wheel side plate 2 at the front end of the tooling base plate 1 is for passing through the driven shaft 4, and the second through hole on the wheel side plate 2 at the rear end of the tooling base plate 1 is for passing through the drive shaft 3. Then, the wheels provided at both ends of the drive shaft 3 are drive rear wheels 6, and the wheels provided at both ends of the driven shaft 4 are driven front wheels 7. The drive device 5 drives the drive shaft 3 to rotate forward, the drive shaft 3 drives the drive rear wheels 6 to rotate forward, the drive rear wheels 6 drive the mold lifting tooling to move forward, and further drive the driven front wheels 7 to rotate forward. The mold lifting tooling can drive the web to move forward as a whole until demolding is completed.

[0044] It should be noted that a guide groove is provided on the bottom surface of the support pallet 9. Specifically, the guide groove is provided on the support pallet 9. The top end of the lifting mechanism 8 is provided with a sliding block, and the sliding block is slidably connected to the guide groove. The length direction of the guide groove is consistent with the length direction of the support side plate 10. When the lifting mechanism 8 extends, while the top end of the lifting mechanism 8 rotates relative to the support pallet 9, the sliding block slides relative to the guide groove to ensure that the lifting mechanism 8 can complete the adjustment of the angle between the bottom surface of the support pallet 9 and the top surface of the tooling base plate 1.

[0045] In the second embodiment of the present utility model, the bottom end of the lifting mechanism 8 is directly rotatably connected to the tooling base plate 1. At this time, it is only necessary that the top end of the lifting mechanism 8 is rotatably connected to the bottom surface of the support pallet 9. The angle between the bottom surface of the support pallet 9 and the top surface of the tooling base plate 1 can be flexibly adjusted by the expansion and contraction of the lifting mechanism 8. When the mold lifting tooling is not in use, the lifting mechanism 8 can be contracted to make the bottom surface of the support pallet 9 as close as possible to the top surface of the tooling base plate 1, reducing the overall floor area of the mold lifting tooling and facilitating storage.

[0046] When the present utility model is in use, the web root is lifted by a crane or manually, and the mold lifting tooling is placed below the center line of the web. The lifting mechanism 8 is started, and the lifting mechanism 8 extends to adjust the angle between the bottom surface of the support pallet 9 and the top surface of the tooling base plate 1, so that each roller group on the overall mold lifting tooling is tightly attached to and abuts against the web. The drive device 5 is started, the drive device 5 drives the drive shaft 3 to rotate forward, the drive shaft 3 drives the drive rear wheels 6 to rotate forward, the drive rear wheels 6 drive the mold lifting tooling to move forward, and the mold lifting tooling drives the web to move forward as a whole until the web is gradually separated from the web mold. After the web demolding operation is completed, the lifting mechanism 8 is started to contract it, and the bottom surface of the support pallet 9 is made as close as possible to the top surface of the tooling base plate 1, and the tooling is taken out from below the web.

[0047] In summary, the support side plate 10 supports the web through multiple roller groups, avoiding the problem of the sling squeezing the web and causing damage to it. Moreover, the support side plate 10 has better structural stability than the sling structure, preventing defects such as bruising and large-area deformation of the web, and effectively improving the safety factor of production operations.

[0048] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0049] In this article, specific examples are used to elaborate on the principles and implementation modes of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
