[0002] Fan anchor bolt 17 is a kind of foundation structure that wind turbine (hereinafter referred to as fan) tower drum is fixed to ground, for ensuring that fan does not displace or topple due to external force during operation. As shown in the figure, fan anchor bolt 17 is cylindrical, one end has thread, for connecting anchor plate and pre-stress, the other end is embedded in fan foundation 16, and plays the role of anchoring. Usually, fan anchor bolt 17 is double-ring arrangement, composed of inner ring and outer ring anchor bolt, outer ring anchor bolt bears larger tension and shear force, and inner ring anchor bolt mainly plays the role of auxiliary anchoring and adjusting stress. Figure 1

[0003] Fan anchor bolt 17 needs to be accepted after construction, to ensure that the structure is safe and reliable. Its acceptance items include position deviation inspection, to check whether the installation position, spacing, perpendicularity and other of anchor bolt meet the design requirements. At present, the means of steel ruler measurement is used, that is, the center line, edge line or other fixed reference point of fan foundation 16 is taken as reference, the deviation value of center position of each anchor bolt from design position is measured, and recorded. Generally, when there is no special regulation, the position deviation does not exceed 5mm.

[0004] However, due to the large number of fan anchor bolts 17, there is a serious problem of low efficiency when checking the position deviation of fan anchor bolt 17 by the above-mentioned method. INVENTION CONTENTS

[0005] To solve the above problems in the prior art, the utility model aims to provide a kind of quick acceptance tool of fan anchor bolt position accuracy, to reach the purpose of improving acceptance efficiency.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only for illustrating and understanding the present application, and are not intended to limit the present application.

[0022] The present embodiment discloses a quick acceptance tool for fan anchor bolt position accuracy, as shown in Figure 2 and Figure 3 , the present embodiment includes a base 1, a rotating rod 3 rotatably assembled on the base 1, and a positioning assembly 5 assembled on the free end of the rotating rod 3.

[0023] The base 1 is a circular structure, which can be stably placed at the center position of the fan foundation 16 during use. Further, as shown in Figure 2 , the mounting shaft 2 extends vertically upward at the center position of the base 1, which is used to rotatably mount the rotating rod 3.

[0024] One end of the rotating rod 3 is rotatably assembled on the mounting shaft 2, and the other end extends horizontally to form the free end of the rotating rod 3. It should be noted that when the base 1 is placed at the center position of the fan foundation 16, the length of the rotating rod 3 is just enough to accurately position the positioning assembly 5 on the fan anchor bolt 17 on the fan foundation 16, which can be referred to in detail in Figure 4 . Of course, according to the actual situation, the rotating rod 3 can also be set as a telescopic rod with adjustable length. Further, as shown in Figure 2 and Figure 3 , the free end of the rotating rod 3 is provided with a vertical guide groove 4 for assembling the positioning assembly 5.

[0025] The positioning assembly 5 includes a sliding frame 6, a sliding block 7, and a positioning sleeve 8. As shown in Figure 3 , the sliding frame 6 is a rectangular frame, one end of which is fixedly provided with a guide block 9 matched with the above-mentioned guide groove 4. By placing the guide block 9 in the guide groove 4, the assembly of the sliding frame 6 on the free end of the rotating rod 3 can be achieved. The sliding block 7 is provided with two, which are both sleeved on the sliding frame 6 and can slide along the length direction of the sliding frame 6. Further, as shown in Figure 3As shown in the drawings, each sliding block 7 is provided with a through slot. A positioning sleeve 8 is assembled in each through slot. Specifically, the positioning sleeve 8 comprises a limiting ring 10 and a sliding sleeve ring 11 which are fixedly connected. The sliding sleeve ring 11 is sleeved on the sliding block 7, the limiting ring 10 is arranged in the through slot, and the inner diameter of the limiting ring 10 is adapted to the outer diameter of the fan anchor bolt 17 (usually, the inner diameter of the limiting ring 10 is slightly larger than the outer diameter of the fan anchor bolt 17). In actual use, the sliding direction of the positioning sleeve 8 on the sliding block 7 is in the width direction of the sliding frame 6.

[0026] As shown in the drawings, Figure 3 In the embodiment, the first scale 12 and the second scale 13 are both 1cm.

[0027] More specifically, the first reset spring 14 is connected between the sliding frame 6 and each sliding block 7 in the embodiment, and when the first reset spring 14 is in a natural state, the sliding block 7 is in a standard position. Similarly, the second reset spring 15 is connected between the sliding block 7 and the sliding sleeve ring 11 of the positioning sleeve 8, and when the second reset spring 15 is in a natural state, the positioning sleeve 8 is in a standard position.

[0028] When the embodiment is used, first, the base 1 is placed at the center of the fan base 16, and then the rotating rod 3 is operated to rotate to two fan anchor bolts 17 in the same radial direction. Then, the sliding frame 6 is lifted so that the two positioning sleeves 8 on the sliding frame 6 correspond to one fan anchor bolt 17 respectively, and then the sliding frame 6 is lowered so that the two positioning sleeves 8 are sleeved on the two fan anchor bolts 17 in the same radial direction, as shown in the drawings. Figure 4 When the fan anchor bolt 17 has a position deviation in the radial direction, for example, the distance between the two fan anchor bolts 17 deviates or the distance between the fan anchor bolt 17 and the center of the fan base 16 deviates, the position of the sliding block 7 on the sliding frame 6 will change. When the fan anchor bolt 17 has a position deviation in the tangential direction, for example, the two fan anchor bolts 17 are not in the same radial direction, the position of the positioning sleeve 8 on the sliding block 7 will change. By observing the position change of the positioning sleeve 8 on the sliding block 7 and the position change of the sliding block 7 on the sliding frame 6, and by reading the second scale 13 and the first scale 12 to obtain the corresponding deviation value, it can be judged whether the position of the fan anchor bolt 17 meets the standard requirements.

[0029] After the measurement, the sliding frame 6 is lifted to make the positioning sleeve 8 disengage from the fan anchor bolt 17, the sliding block 7 is reset to the standard position under the action of the first reset spring 14, and the positioning sleeve 8 is reset to the standard position under the action of the second reset spring 15; then the rotating rod 3 is operated to rotate to the two fan anchor bolts 17 of the same radial direction of the lower group to repeat the above process, so that the position accuracy of all the fan anchor bolts 17 on the fan foundation 16 can be detected and accepted in sequence.

[0030] It should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments, or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
