Description

Technical Field

[0001] This utility model relates to the field of installation and construction technology for new energy projects, and in particular to a wind turbine cushion layer leveling device. Background Technology

[0002] With the leapfrog iteration of wind turbine technology, my country's new energy power industry has shown a geometric growth trend. The single unit capacity of wind turbines has achieved a breakthrough from the initial 3kW level to the modern 10MW level. Along with the exponential increase in the size of the foundation structure, the construction area of ​​the foundation layer has also shown an exponential expansion, which poses an engineering challenge for the ultra-large volume foundation layer of megawatt-level wind turbines.

[0003] Existing technologies often have the following drawbacks: the surface flatness of the foundation pad is a core indicator for the quality control of pad construction, and its geometric accuracy directly determines the load transfer performance and long-term stability of the superstructure. Traditional wind turbine pad flatness cannot meet the requirements of construction accuracy.

[0004] Therefore, this utility model provides a fan cushion leveling device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the flatness of traditional wind turbine cushion layers cannot meet the requirements of construction precision, and to propose a wind turbine cushion layer flattening device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fan pad leveling device, comprising four channel steels arranged in an alternating pattern, with U-shaped limiting blocks fitted on both sides of each channel steel, a positioning block fixedly connected to the side wall of each limiting block, and a drive rod internally threaded to the positioning block.

[0007] The effect achieved by the above components is that after the U-shaped limiting block is placed on the bottom side of the channel steel, the installation height of the side of the channel steel can be adjusted by rotating the drive rod, thereby ensuring that the elevation deviation of the pad surface is within the control range.

[0008] Preferably, the positioning block has a sliding plate inside, and a pad is fixedly connected to the lower end of the sliding plate.

[0009] The effect achieved by the above components is that rotating the drive rod can drive the pad, thereby enabling the adjustment of the installation height of the channel steel side.

[0010] Preferably, the drive rod and the pad are internally rotatably connected.

[0011] The effect achieved by the above components is to rotatably connect the drive rod and the pad, so that the pad can be lifted when the drive rod is rotated in the opposite direction.

[0012] Preferably, the limiting block has an internal threaded connection with a bolt.

[0013] The effect achieved by the above components is that rotating the bolts makes it easier to fix the limiting block on the channel steel.

[0014] Preferably, the lower surface of the pad is fixedly connected with a plurality of spikes.

[0015] The effect achieved by the above-mentioned components is that the spikes improve the stability of the channel steel when placed and supported on the soil.

[0016] Preferably, the outer surface of several of the spikes is covered with a rubber pad.

[0017] The effect achieved by the above-mentioned components is that the rubber pad covering the outer surface of the spikes can flexibly cover and protect the spikes, thereby improving the safety of carrying the pad.

[0018] Preferably, the lower surface of the rubber pad is provided with anti-slip texture.

[0019] The effect achieved by the above components is that the anti-slip texture increases the friction between the mat and the hard ground, and the staff can flexibly install the rubber mat on the mat for use according to their needs.

[0020] In summary:

[0021] In this invention, four sets of channel steel support systems are arranged equidistantly along the foundation pad. After the top surface of the channel steel is checked by the three-dimensional coordinates of a total station, a hydraulic synchronous fine-tuning device is used to correct the elevation at the millimeter level, forming a closed horizontal reference ring. During construction, an automatic scraper is configured to travel back and forth along the channel steel guide rail, dynamically adjusting the inclination angle and travel speed of the vibrating beam to ensure that the elevation deviation of the pad surface is within the control range. By setting up the above structure, the construction efficiency is effectively improved, the construction quality is guaranteed, and the labor input is reduced. Attached Figure Description

[0027] Reference Figure 1-4 As shown, this utility model provides a technical solution: a fan pad leveling device, comprising four channel steels 1 arranged in an alternating pattern. U-shaped limiting blocks 3 are fitted onto both sides of each channel steel 1. Positioning blocks 4 are fixedly connected to the side walls of the limiting blocks 3, and drive rods 7 are threadedly connected to the internal surfaces of the positioning blocks 4. The effect achieved by these components is that after the U-shaped limiting blocks 3 are fitted onto the bottom side of the channel steel 1, the installation height of the side of the channel steel 1 can be adjusted by rotating the drive rod 7, thereby ensuring that the elevation deviation of the pad surface is within a controlled range.

[0028] The following is a detailed explanation of its overall setup and function.

[0029] In this implementation scheme: A sliding plate 6 is internally slidably connected to the positioning block 4, and a pad 2 is fixedly connected to the lower end of the sliding plate 6. Rotating the drive rod 7 drives the pad 2, thereby adjusting the installation height of the channel steel 1. The drive rod 7 and the pad 2 are internally rotatably connected. Rotating the drive rod 7 in the opposite direction lifts the pad 2. A bolt 5 is internally threaded onto the limiting block 3. Rotating the bolt 5 facilitates fixing the limiting block 3 to the channel steel 1. Several spikes 9 are fixedly connected to the lower surface of the pad 2. The spikes 9 improve the stability of the channel steel 1 when placed and supported on the soil surface.

[0030] Specifically, several spikes 9 have rubber pads 8 covering their outer surfaces. These rubber pads 8 provide flexible coverage and protection for the spikes 9, thus improving the safety of carrying the pad 2. The lower surface of the rubber pads 8 has anti-slip textures. These textures increase the friction between the pad 2 and the hard ground, allowing workers to flexibly install the rubber pads 8 onto the pad 2 as needed.

[0031] Working principle: This scheme proposes to use a channel steel 1 component with the same design height as the subgrade, which will serve as the initial positioning benchmark to accurately control the elevation and surface flatness during subsequent construction. After the U-shaped limiting block 3 is placed on the bottom side of the channel steel 1, rotating the bolt 5 facilitates fixing the limiting block 3 to the channel steel 1. By rotating the drive rod 7, the installation height of the side of the channel steel 1 can be adjusted, thereby ensuring that the elevation deviation of the subgrade surface is within the control range. Rotating the drive rod 7 can drive the pad 2, thereby adjusting the installation height of the side of the channel steel 1. The drive rod 7 and the pad 2 are rotatably connected. Rotating the drive rod 7 in the opposite direction can lift the pad 2. The spikes 9 improve the stability of the channel steel 1 when placed and supported on the soil surface. Rubber pad 8... The rubber pad 8, fitted onto the outer surface of the spike 9, provides flexible coverage and protection, thereby improving the safety of carrying the pad 2. The anti-slip texture increases the friction between the pad 2 and the hard ground. Workers can flexibly install the rubber pad 8 onto the pad 2 according to their needs. In practice, four sets of channel steel 1 support systems are arranged equidistantly along the foundation pad. After the top surface of the channel steel 1 is checked by the three-dimensional coordinates of the total station, a hydraulic synchronous fine-tuning device is used to correct the elevation at the millimeter level, forming a closed horizontal reference ring. During construction, an automatic scraper will be configured to move back and forth along the guide rail of the channel steel 1, dynamically adjusting the inclination angle and travel speed of the vibrating beam to ensure that the elevation deviation of the pad surface is within the control range. By setting up the above structure, construction efficiency is effectively improved, construction quality is guaranteed, and labor input is reduced.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
