Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic torque wrenches, and in particular to a hydraulic torque wrench support fixture for assembling the yaw system of a wind turbine. Background Technology

[0002] During the assembly of the yaw system of a wind turbine generator set, the connection between the front and rear yaw bases requires the use of a hydraulic torque wrench for bolt tightening. Currently, the reaction arm support of the hydraulic torque wrench is usually provided by wooden blocks, which presents several problems:

[0003] 1. The wooden blocks cannot be firmly fixed, resulting in frequent displacement during production operations, which greatly increases the complexity and inconvenience of the operation;

[0004] 2. When torque is applied, the wooden blocks are prone to popping out, which not only affects the assembly accuracy and efficiency, but also poses a high safety hazard and can easily cause injury to the operators.

[0005] Therefore, there is an urgent need to design a support structure that is easy to operate and has stable and reliable performance in order to optimize this assembly process, improve production efficiency, and ensure operational safety. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a hydraulic torque wrench support tool for assembling the yaw system of wind turbine units. It has the advantages of simple structure, convenient operation, improved production efficiency, high safety, and stable and reliable performance.

[0007] The objective of this utility model can be achieved by adopting the following technical solutions:

[0008] A hydraulic torque wrench support fixture for assembling a wind turbine yaw system includes an upper positioning bracket, a lower L-shaped base, and two wrench limiting blocks. The upper positioning bracket has a U-shaped structure with its opening facing the yaw platform of the yaw system. The U-shaped structure is secured to the edge of the support plate of the yaw platform. The top edge of the lower L-shaped base is connected to the bottom of the upper positioning bracket. The front side of the lower L-shaped base is supported on the yaw rear base of the yaw platform. Two wrench limiting blocks are symmetrically arranged at the left and right ends of the rear corner of the lower L-shaped base to limit the reaction arm of the hydraulic torque wrench supported at the corner of the lower L-shaped base. The distance between the two wrench limiting blocks matches the width of the reaction arm of the hydraulic torque wrench.

[0009] Furthermore, the bottom of the upper positioning bracket is provided with reinforcing ribs to enhance the structural strength of the upper positioning bracket.

[0010] Furthermore, the lower L-shaped base includes a vertical connecting plate and a horizontal connecting plate. The front side of the horizontal connecting plate is supported on the yaw rear base of the yaw platform. The rear side of the horizontal connecting plate is welded to the bottom side of the vertical connecting plate. Two wrench limiting blocks are symmetrically arranged at the left and right ends of the bottom of the rear side of the horizontal connecting plate. The top side of the vertical connecting plate is welded to the bottom of the upper positioning bracket.

[0011] Furthermore, a reinforcing rib plate is connected between the vertical connecting plate and the horizontal connecting plate to strengthen the structure of the lower L-shaped base, forming a stable triangular structure with the reinforcing rib plate, the vertical connecting plate and the horizontal connecting plate.

[0012] Furthermore, the upper positioning bracket, the lower L-shaped base, and the reinforcing ribs are all carbon steel or stainless steel structural components.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] The supporting fixture of this utility model has a simple structure. It is supported on the edge of the support plate of the yaw platform by the upper positioning bracket of the U-shaped structure, so as to achieve temporary and firm fixation of the fixture. It is easy to operate and improves production efficiency. At the same time, the reinforcing ribs, vertical connecting plates and horizontal connecting plates form a stable triangular structure. By utilizing the stability and strong load-bearing capacity of the triangular structure, the stress point is located at the maximum load-bearing point, which enhances the safety and performance of the supporting fixture.

[0017] 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.

[0018] like Figure 1As shown, this embodiment provides a hydraulic torque wrench support fixture for assembling the yaw system of a wind turbine, including an upper positioning bracket 1, a lower L-shaped base, and two wrench limiting blocks 4. The upper positioning bracket 1 has a U-shaped structure, with the opening of the U-shaped structure facing the yaw platform of the yaw system. The U-shaped structure is clamped to the edge of the support plate 7 of the yaw platform. The top edge of the lower L-shaped base is connected to the bottom of the upper positioning bracket 1. The front side of the lower L-shaped base is supported on the yaw rear base 8 of the yaw platform. Two wrench limiting blocks 4 are symmetrically arranged at the left and right ends of the rear corner of the lower L-shaped base to limit the reaction arm of the hydraulic torque wrench supported at the corner of the lower L-shaped base. The distance between the two wrench limiting blocks 4 matches the width of the reaction arm of the hydraulic torque wrench.

[0019] The bottom of the upper positioning bracket 1 is provided with reinforcing ribs 6 to enhance the structural strength of the upper positioning bracket 1.

Two wrench limit blocks 4 are symmetrically arranged at the left and right ends of the bottom of the rear side of the horizontal connecting plate 3. The top side of the vertical connecting plate 2 is welded to the bottom of the upper positioning bracket 1.

[0021] A reinforcing rib plate 5 is connected between the vertical connecting plate 2 and the horizontal connecting plate 3 to strengthen the structure of the lower L-shaped base. The reinforcing rib plate 5, the vertical connecting plate 2 and the horizontal connecting plate 3 form a stable triangular structure. The force is concentrated and directed to the lower L-shaped base through the triangular structure. By utilizing the stability and strong load-bearing capacity of the triangular structure, the stress point is located at the maximum load-bearing point, which enhances the safety and performance of the support fixture.
