Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine blade production, and in particular to a tooling for creating a mold in the middle of a double-roller blade. Background Technology

[0002] With the development of wind power technology, the length of wind turbine blades has increased from over 50 meters to over 130 meters, and the weight of the blades has also increased significantly, from 10 tons to 35 to 40 tons. After the blades are manufactured, they are usually lifted from the mold using a two-point lifting method. Because the lifting point in the middle of the blade is biased towards the blade root, the weight of the blade at the lifting point is too heavy, exceeding the rated load range of the existing 20-ton overhead crane. This poses a risk of damage to the crane and cannot meet the production requirements of the blades. To improve this problem, the crane's load capacity is usually increased to 25 to 30 tons. However, the current design tonnage of the existing factory crane cannot meet the load capacity requirements of replacing it with a new crane, and the system replacement cost is too high. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tooling for removing molds in the middle of double gantry blades. This tooling can effectively solve the problem that the existing tooling exceeds the rated load range of the gantry when removing molds in the middle of blades, which poses a risk of damage to the gantry and cannot meet the production needs of blades.

[0004] The objective of this utility model can be achieved by adopting the following technical solutions: A tooling for removing molds from the blades of a double-roller crane includes a tooling body, a mold-removing bracket, a lifting strap, and a load-bearing lifting ring. The mold-removing bracket is vertically connected to the tooling body, forming a cross structure. Both ends of the mold-removing bracket are connected to the blades via the lifting strap, and both ends of the tooling body are connected to two cranes via load-bearing lifting rings.

[0005] Furthermore, the tooling body includes a first profile and two second profiles symmetrically arranged on both sides of the middle of the first profile, and the second profiles are perpendicularly connected to the first profile, forming a cross-shaped structure.

[0006] Furthermore, a reinforcing rib is provided between the first profile and the second profile.

[0007] Furthermore, both the first profile and the second profile are H-beams.

[0008] Furthermore, the mold-lifting bracket is connected to the tooling body through two sets of connecting plates. The two sets of connecting plates are symmetrically welded to the top of the tooling body, and the distance between the two sets of connecting plates is adapted to the width of the mold-lifting bracket. The mold-lifting bracket is placed between the two sets of connecting plates and connected to the connecting plates by fixing bolts.

[0009] Furthermore, the mold-raising bracket is generally triangular in shape, with slots for connecting slings at both ends of its base.

[0010] Furthermore, multiple reinforcing columns are provided between the bottom edge and the two inclined sides of the mold-forming bracket to enhance structural stability.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model has the advantages of simple structure, convenient operation and low cost. It adopts a double crane blade in-mold lifting fixture, which can adjust the blade in-mold lifting from the original single crane to double crane. The two cranes share the weight of the blade in-mold, avoiding exceeding the rated load range of a single crane, effectively meeting the blade lifting requirements and ensuring normal blade production.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, this embodiment provides a tooling for removing molds in the middle of double crane blades, including a tooling body 1, a mold removal bracket 2, a lifting strap 3, and a load-bearing lifting ring 4. The mold removal bracket 2 is vertically connected to the tooling body 1, and the two form a cross structure. The two ends of the mold removal bracket 2 are connected to the middle of the blade 5 through the lifting strap 3, and the two ends of the tooling body 1 are respectively connected to two cranes through the load-bearing lifting ring 4.

[0017] The tooling body 1 includes a first profile 101 and two second profiles 102 symmetrically arranged on both sides of the middle part of the first profile 101. The second profiles 102 are perpendicularly connected to the first profile 101, and the three form a cross-shaped structure.

[0018] In this embodiment, the first profile 101 and the second profile 102 are made of H-beams, and the length of the first profile 101 is greater than the length of the second profile 102.

[0019] To enhance the structural strength of the tooling body 1, a reinforcing rib 103 is provided between the first profile 101 and the second profile 102.

[0020] The overall shape of the mold-lifting bracket 2 is triangular. The two ends of its bottom side 201 are provided with slots 2011 for connecting the slings 3, and multiple reinforcing columns 203 are provided between its bottom side 201 and the two inclined sides 202 to enhance the stability of the structure.

[0021] The mold-removing bracket 2 is connected to the tooling body 1 through two sets of connecting plates 6. Each set of connecting plates 6 has multiple plates. In this embodiment, three plates are used as an example. The two sets of connecting plates 6 are symmetrically welded to the top of the tooling body 1, and the distance between the two sets of connecting plates 6 is adapted to the width of the mold-removing bracket 2. The mold-removing bracket 2 is placed between the two sets of connecting plates 6 and connected to the connecting plates 6 through fixing bolts 7, thereby completing the assembly of the tooling.

[0022] The method of using the double-blade mid-stage mold-lifting tool in this embodiment is as follows: S1. Place the mold-lifting bracket between the two sets of connecting plates on the top of the tooling body, and fix the mold-lifting bracket with fixing bolts to assemble the mold-lifting bracket and the tooling body into a whole.

[0023] S2. In this embodiment, the total weight of the blade is 34t, the weight of the lifting point in the blade is about 19.5t, the weight of the mold-lifting bracket + sling is about 200kg, the weight of the blade burrs is about 800kg, and the weight of the blade in the middle exceeds 20t. The two ends of the tooling body are respectively suspended on two overhead cranes. Then, the sling is passed through the lifting position in the middle of the blade and its two ends are hung on the two ends of the mold-lifting bracket.

[0024] S3. Use one overhead crane to lift the root section of the blade, and use two other overhead cranes to lift the middle section of the blade through a double overhead crane blade lifting fixture. All three overhead cranes are conventional 20t overhead cranes. Simultaneously start the three overhead cranes to raise the blade upwards in a synchronous manner. After the blade lifting height exceeds the horizontal height of the mold by about 1m, simultaneously operate the three overhead cranes to move the blade and place it in the preset position.

Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in this utility model patent, based on the technical solution and utility model patent concept of this utility model patent, shall fall within the protection scope of this utility model patent.
