Embodiment Construction

[0035] Specific embodiments of the present invention are given below. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations made on the basis of the technical solutions of the present application fall into the protection scope of the present invention.

[0036] Follow the above technical solutions, such as Figure 1 to Figure 2 As shown, this embodiment provides a sleeve-type measuring device and method for measuring the elongation of the fan foundation anchor bolt. By placing the sleeve outside the anchor bolt, the anchor bolt causes the displacement of the limit baffle in the sleeve, Through the observation hole of the limit baffle, observe the cylinder scale corresponding to the lower surface of the limit baffle, and measure the elongation of the anchor bolt.

[0037] The present invention is a wind power foundation anchor bolt elongation measuring device, comprising a sleeve, a sliding mechani...

Abstract

The invention discloses a device and a method for measuring the elongation of a wind power foundation anchor bolt. The device comprises a sleeve, a sliding mechanism and a scale device, the method comprises the steps that (1) a barrel is pressed downwards, a limiting baffle moves upwards along a guide rod under the counter-acting force of an anchor bolt, and after the bottom end face of the barrel and the upper surface of a tower barrel flange are compacted, the scale of a graduated scale corresponding to the lower surface of the limiting baffle is the extension length of the anchor bolt; (2) the starting scale of the graduated scale starts from the thickness scale of the shoulder of the cylinder, so that the elongation length of the anchor bolt can be directly measured; and (3) when the sleeve does not work, the limiting baffle is pressed by the compression spring and clings to the shoulder of the sleeve body to prevent the reciprocating action of the sliding mechanism. The anchor bolt is sleeved with the sleeve, the anchor bolt causes displacement of the limiting baffle in the sleeve, and the length of the anchor bolt is obtained through the limiting baffle observation hole according to the graduation ruler of the barrel and the graduation corresponding to the lower surface of the limiting baffle.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a device and method for measuring the elongation of an anchor bolt of a wind power foundation. Background technique [0002] After the wind power foundation anchor bolts are tensioned, the elongation of the anchor bolts needs to be measured to evaluate the quality status of the wind turbine foundation and the anchor bolts. The existing technology mainly adopts the combination of a vernier caliper and a baffle or a combination of a tape measure and a baffle. Measurement, the above measurement technology mainly has the following shortcomings: [0003] 1. Since the contact surface of the vernier caliper or tape measure and the tower flange is in point contact, it cannot be guaranteed that the contact point between the vernier caliper / tape measure and the tower flange is the same point when measuring before and after tensioning, and the tower flange is affec...
