Description

Technical Field

[0001] The utility model relates to a device for measuring the exposed length of prestressed anchor bolts of a fan foundation. Background Art

[0002] Prestressed anchor bolts are widely used in onshore wind turbine foundations. Strict requirements are placed on the installation of anchor bolts during construction. The allowable error in the leakage length of the anchor bolts from the anchor plate is generally around ±1mm. The workers' skills vary greatly. At the same time, there is a lack of a device that can accurately and quickly determine the leakage length of the anchor bolts, which creates difficulties for construction quality and progress and is prone to errors. Utility Model Content

[0003] The purpose of the utility model is to provide a device for measuring the exposed length of prestressed anchor bolts in a wind turbine foundation in order to solve the above-mentioned problems.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A device for measuring the exposed length of prestressed anchor bolts in a wind turbine foundation comprises an outer sleeve, an inner ring plate and a plurality of abutment frames. The outer sleeve and the inner ring plate are connected by bearings. The plurality of abutment frames are evenly arranged in a circle with the center of the outer sleeve as the center of the circle. A plurality of push blocks evenly arranged along the inner ring surface of the inner ring plate are fixed inside the inner ring plate, and the push blocks push the abutment frames to move.

[0006] The device for measuring the exposed length of prestressed anchor bolts of a wind turbine foundation comprises a support frame including a back plate and a rule plate, the rule plate is fixed to the back plate, a plurality of limit links are passed through the back plate, the ends of the limit links are fixed to the outer wall of the outer sleeve, and each limit link is provided with a spring.

[0007] The device for measuring the exposed length of prestressed anchor bolts of a wind turbine foundation is characterized in that the push block is a triangular push block.

[0008] The device for measuring the exposed length of prestressed anchor bolts of a wind turbine foundation is provided with observation openings distributed in a circumferential manner on the outer side wall of the outer sleeve. Beneficial effects

[0009] 1. The utility model is put on the anchor bolt, and the bottom of the guide plate contacts the anchor plate. In this way, the exposed length of the anchor bolt can be read by the scale on the guide plate when the guide plate is against the anchor bolt, so that the exposed length of the anchor bolt can be quickly measured.

[0010] 2. The utility model provides a plurality of abutting frames, and the ruler plates of the plurality of abutting frames abut against the anchor bolts, so that the scales on the two opposite ruler plates can be read, thereby ensuring the accuracy of reading the exposed length of the anchor bolts.

[0011] 3. The utility model has a simple structure. By rotating the inner ring plate, the triangular push block can be brought into contact with the ruler plate at different positions, thereby changing the position of the ruler plate and realizing the measurement of anchor bolts with different diameters.

[0019] Reference Figures 1-4 A device for measuring the exposed length of prestressed anchor bolts in a wind turbine foundation comprises an outer sleeve 8, an inner ring plate 13 and a plurality of abutment frames 11, wherein the outer sleeve and the inner ring plate are connected by a bearing, and the plurality of abutment frames are evenly arranged in a circle with the center of the outer sleeve as the center;

[0020] The abutment frame includes a back plate 5 and a straightedge plate 4. The straightedge plate is fixed to the back plate. A plurality of limiting links 6 are passed through the back plate. The ends of the limiting links are fixed on the outer wall of the outer sleeve. There is a notch 3 on the straightedge plate. This notch is for facilitating the movement of the straightedge plate position. At the same time, a socket 14 is provided on the side wall of the outer sleeve at the position where the straightedge plate passes. This socket is for the straightedge plate to pass through the outer sleeve. A spring 12 is provided on each of the limiting links.

[0021] A plurality of push blocks 1 are fixed inside the inner ring plate and are evenly arranged along the inner ring surface of the inner ring plate. The push blocks are triangular push blocks, and the abutment frame is pushed to move by the push blocks.

[0022] A twisting head 7 is fixed on the inner ring plate. When operating, the twisting head is twisted to rotate the inner ring plate, thereby changing the position of the triangular push block.

[0023] The bottom of the guide plate has a cutout 17 .

[0024] The outer side wall of the outer sleeve is provided with observation openings 9 distributed in a circumferential manner.

[0025] Working principle: Refer to Figure 5-Figure 6 The cam is then rotated counterclockwise to move the inner ring plate in a direction opposite to the center of the spring, and the cam is then moved ...
