[0010] Furthermore, the fixing member is threadedly connected to a backing member at the bent end, and the backing member abuts against the embedded part through a top protrusion structure, and a drive handwheel is provided at the bottom of the backing member.

[0011] Furthermore, the embedded part is provided with the positioning groove on the top protrusion side, and the positioning posts are distributed around the bottom of the base ring through the connecting flange, with the bottom of the positioning posts having a conical structure.

[0012] Furthermore, the guiding component includes a mounting base, on which a first wedge block is slidably connected via a groove, and a driving member is fixedly connected to the top of the mounting base, the driving member being used to drive the first wedge block to slide.

[0013] Furthermore, it also includes a guide plate, on the side of the guide plate away from the base ring, a second wedge block is provided, and guide rods are provided on both sides of the second wedge block. The first wedge block and the second wedge block slide against each other through wedge surfaces, and the guide rods are slidably connected to the mounting base by springs.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A wind turbine foundation ring quick positioning and installation device includes a base 1, with a plurality of embedded parts 2 arranged around the outer edge of the center point on the top of the base 1. The top of the embedded parts 2 is connected to a base plate 4 through a fixing component 3. A guide component 5 is provided on the top of the base plate 4. The foundation ring 6 is concentrically set with the center point of the base 1 through the guide component 5.

[0024] The pre-embedded part 2 is provided with a positioning groove 41 at the top, and the positioning post 61 located at the bottom of the foundation ring 6 is placed in the positioning groove 41 by the guide component 5.

[0025] It should be added that the base 1 is the connection foundation between the base ring 6 and the ground. The base ring 6 is erected on several embedded parts 2, and the base 1, embedded parts 2 and base ring 6 are integrated by welding, casting and other methods.

[0026] Furthermore, the fixing component 3 includes at least one fixing member 31, which has an L-shaped structure and is fixedly connected to the bottom side of the base plate 4. The embedded part 2 has an I-shaped structure, and a receiving groove 21 is provided at the top protrusion of the embedded part 2. The fixing member 31 is located in the receiving groove 21.

[0027] Furthermore, the fixing member 31 is threadedly connected to the abutment member 32 at the bent end. The abutment member 32 abuts against the embedded part 2 through a top protrusion structure. A drive handwheel is provided at the bottom of the abutment member 32.

[0028] In this embodiment, the base plate 4 and the fixing member 31 form a C-shaped structure. The two ends of the embedded member 2 are provided with rectangular protrusions. By driving the handwheel to rotate the abutment member 32, the abutment member 32 abuts against the rectangular protrusion through the top protrusion structure, and cooperates with the base plate 4 to achieve the function of fixing the guide component 5.

[0029] More specifically, the embedded part 2 is provided with the positioning groove 41 on the top protrusion side, and the positioning posts 61 are distributed around the bottom of the base ring 6 through the connecting flange, and the bottom of the positioning posts 61 has a conical structure.

[0030] In some embodiments, the base ring 6 is lifted by a lifting device. Under the action of several guiding components 5, the suspended base ring 6 is aligned with the center point of the base 1. Then, the positioning post 61 is inserted into the positioning groove 41 by manually guiding the angle.

[0031] In general, the guide component 5 includes a mounting base 51, a first wedge block 52 is slidably connected to the side of the mounting base 51 via a sliding groove, and a drive member 53 is fixedly connected to the top of the mounting base 51, the drive member 53 being used to drive the first wedge block 52 to slide.

[0032] Finally, it also includes a guide plate 54, on the side of the guide plate 54 away from the base ring 6, a second wedge block 55 is provided, and guide rods 56 are provided on both sides of the second wedge block 55. The first wedge block 52 and the second wedge block 55 slide against each other through the wedge surface, and the guide rods 56 are slidably connected to the mounting base 51 through springs 57.

[0033] The guide plate 54 abuts against the connecting flange at the bottom of the base ring 6.

[0034] It should be added that the driving component 53 can be driven by a motor to drive the lead screw, so that the first wedge block 52 is threadedly connected to the lead screw to drive the first wedge block 52 to move, or the shaft end of a cylinder or electric push rod can be connected to the first wedge block 52 to achieve the driving sliding effect.

[0035] Among them, such as Figure 5 As shown, the wedge surfaces of the first wedge block 52 and the second wedge block 55 are arranged opposite each other, and the width of the wedge surface of the second wedge block 55 gradually increases from top to bottom. Then, driven by the first wedge block 52, the second wedge block 55, in conjunction with the guide rod 56 and the spring 57, achieves a lateral movement.

[0036] In this process, once the guide plate 54 on the outer edge is vertical, the guide plate 54 abuts against the flange at the bottom of the base ring 6, causing the positioning post 61 to engage in the positioning groove 41, and ensuring that the center point of the base ring 6 and the base 1 are concentrically set, thus achieving the positioning function.

[0037] Furthermore, the guide rod 56 has a T-shaped cross-section, and the two ends of the spring 57 abut against the protrusion at one end of the guide rod 56 and the side of the mounting base 51, respectively, so that the second wedge block 55 is reset by the spring 57.

[0038] Working method: During operation, several pre-embedded parts 2 are embedded outside the center point of the top of the base 1. The foundation ring 6 is lifted by lifting equipment and placed between several guide components 5.

[0039] The drive component 53 slides through the first wedge block 52. The first wedge block 52 slides through the wedge surface of the second wedge block 55, so that the guide plate 54 is in contact with the flange at the bottom of the base ring 6. At this time, the positioning pin 61 is inserted into the positioning groove 41 by manually guiding the angle.

[0040] By rotating the handwheel to rotate the abutment 32, the abutment 32 disengages from the top protrusion of the embedded part 2, and the entire fixing assembly 3 and base plate 4 can be disassembled. Then, the base 1, the embedded part 2 and the foundation ring 6 are integrated by welding, casting and other methods.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
