Description

Technical Field

[0001] The utility model relates to a steel bar positioning device, in particular to a steel bar binding and fixing device for a fan foundation, belonging to the technical field of fan foundation construction. Background Art

[0002] With the increase in the capacity of single wind turbines, wind turbine foundations are getting larger and larger. The amount of steel bars used in the foundation of a 6.25MW model has reached 78 tons, and the onshore single-unit capacity has reached 10MW, with even greater amounts of steel bars used. When tying the steel cage, it is necessary to measure and mark the height of the steel tying before point-by-point tying can be carried out. As the diameter and amount of steel bars increase, the weight increases, and after the upper steel bars are tied, the cage will fall as a whole. When steel workers tie the cage according to the measured dimensions, it is easy to cause the spacing between the steel bars to be lax, resulting in the cage as a whole exceeding or falling below the elevation. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a wind turbine foundation steel bar binding and fixing device, which can accurately control the binding height of the steel bars and improve the quality and efficiency of construction.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A wind turbine foundation reinforcement binding and fixing device comprises an outer guard plate, a U-shaped positioning plate and a first adjustment plate. The outer guard plates are two, and a U-shaped positioning plate is arranged between the two outer guard plates. A matching second adjustment plate is inserted into the U-shaped positioning plate. The outer guard plate, the U-shaped positioning plate and the second adjustment plate are fixed together by bolts.

[0006] Three first mounting holes are arranged at intervals in the middle of the lower side of the outer guard plate, two second mounting holes are arranged at intervals in the middle of the U-shaped positioning plate, and the spacing between adjacent first mounting holes is the same as the spacing between adjacent second mounting holes.

[0007] An observation hole is arranged on the upper side of one of the outer guard plates, and a scale is arranged on the outer side of the observation hole.

[0008] An adjusting slot is arranged in the middle of the second adjusting plate.

[0009] A first bolt is arranged between the U-shaped positioning plate and the two outer guard plates, and a second bolt is arranged between the second adjustment plate and the U-shaped positioning plate and the two outer guard plates.

[0010] The outer ends of the second adjustment plate and the U-shaped positioning plate are respectively provided with end plates.

[0011] The positive beneficial effects of the utility model are:

[0012] 1. The utility model inserts an adjustment plate in the U-shaped positioning plate. When in use, the position of the adjustment plate can be adjusted according to the installation height of the steel bars to avoid the steel bars from falling during construction, thereby ensuring the accuracy of construction and improving the construction quality.

[0013] 2. The utility model sets an observation hole on the outer guard plate and sets a scale on the outside of the observation hole. During construction, the position of the outer end plate of the adjustment plate can be checked through the observation hole to determine whether the installation height of the steel cage meets the requirements. The utility model is easy to use and simple to operate. The device can be recycled, which reduces the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0021] For example, see Figure 1-Figure 5 A wind turbine foundation steel bar binding and fixing device comprises an outer guard plate 1, a U-shaped positioning plate 2 and a first adjustment plate 3. There are two outer guard plates 1, and a U-shaped positioning plate 2 is arranged between the two outer guard plates 1. A matching second adjustment plate 6 is inserted in the U-shaped positioning plate 2. The outer guard plate 1, the U-shaped positioning plate 2 and the second adjustment plate 6 are fixed together by bolts.

[0022] Three first mounting holes 4 are spaced apart in the middle of the lower side of the outer guard plate 1 , two second mounting holes 5 are spaced apart in the middle of the U-shaped positioning plate 2 , and the spacing between adjacent first mounting holes 4 is the same as the spacing between adjacent second mounting holes 5 .

[0023] An observation hole 7 is provided on the upper side of one of the outer guard plates 1 , and a scale is provided on the outer side of the observation hole 7 .

[0024] An adjustment slot 8 is provided in the middle of the second adjustment plate 6 .

[0025] A first bolt is provided between the U-shaped positioning plate 2 and the two outer guard plates 1 , and a second bolt is provided between the second adjustment plate 6 and the U-shaped positioning plate 2 and the two outer guard plates 1 .

[0026] End plates 9 are respectively provided at the outer ends of the second adjustment plate 6 and the U-shaped positioning plate 2 .

[0027] In the above description, the adjustment plate and the U-shaped positioning plate are plugged together, and the adjustment plate, the U-shaped positioning plate, and the two outer guard plates are fixed together by bolts.

[0028] In the above description, the end plates at the outer ends of the adjustment plate and the U-shaped positioning plate have the same size.

[0029] In the above description, during construction, one device is set up every 4-7 meters according to the outer diameter of the steel bar.

[0030] When in use, a first bolt is set between the U-shaped positioning plate and the two outer guard plates, and a second bolt is set between the adjustment plate, the U-shaped plate and the two outer guard plates, and matching nuts are set at the ends of the two bolts; after the staff has measured the bundling height of the steel bars, the bottom of the device (the end of the U-shaped positioning plate) is clamped on the bottom plate steel bars, and then the position of the adjustment plate is adjusted according to the bundling height of the upper steel bars. After the adjustment is completed, the nuts at the ends of the two bolts are tightened so that the two outer guard plates clamp the two end plates. At this time, the position of the adjustment plate is fixed; the staff clamps the upper steel bars directly above the device (i.e., the upper part of the adjustment plate), and finally, the steel bars can be tied.

[0031] The utility model inserts an adjusting plate in the U-shaped positioning plate, so that the position of the adjusting plate can be adjusted according to the installation height of the steel bars, thereby preventing the steel bars from falling during construction. At the same time, the position of each steel bar can be checked according to the scale on the outside of the observation hole to see whether it meets the requirements, thereby ensuring the accuracy of construction, improving the construction quality, being easy to use, simple to operate, and easy to promote.
