Abstract

The utility model discloses a fan foundation pre-stressed anchor bolt exposed length measuring device. The permissible error of the anchor bolt to the exposed length of an anchor plate is generally about + / -1mm, the levels of workers are uneven, meanwhile, a device capable of accurately and quickly determining the exposed length of the anchor bolt is lacked, the construction quality and progress are difficult, and errors are easily caused. The device comprises a middle supporting arm and two side supporting arms, the middle supporting arm and the two side supporting arms are fixed through bolts, rod penetrating rings are arranged at the ends of the middle supporting arm and the side supporting arms respectively, two scale rods are fixed to the rod penetrating rings, and a sliding plate penetrates through the scale rods and is in sliding fit with the scale rods. The device is used for measuring the exposed length of the fan foundation pre-stressed anchor bolt.

Description

Technical Field

[0001] This utility model relates to a device for measuring the exposed length of prestressed anchor bolts in wind turbine foundations. Background Technology

[0002] Prestressed anchors are widely used in onshore wind turbine foundations. There are strict requirements for anchor installation during construction. The allowable error for the exposed length of the anchor to the anchor plate is generally around ±1mm. The skill level of workers varies, and there is a lack of a device that can accurately and quickly determine the exposed length of the anchor, which makes it difficult to ensure construction quality and progress and is prone to errors. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a device for measuring the exposed length of prestressed anchor bolts in wind turbine foundations.

[0004] The above objectives are achieved through the following technical solutions:

[0005] A device for measuring the exposed length of prestressed anchor bolts in a wind turbine foundation comprises a central support arm and two side supports arm. The central support arm and the two side supports arm are fixed together by bolts. The ends of the central support arm and the side supports arm are respectively provided with rod-through rings. Two scale rods are fixed on the rod-through rings. A sliding plate passes through the scale rods and slides with the scale rods.

[0006] The aforementioned device for measuring the exposed length of prestressed anchor bolts in a wind turbine foundation, wherein the sliding plate is an Ω-plate.

[0007] The aforementioned device for measuring the exposed length of prestressed anchor bolts in wind turbine foundations has a cylindrical graduated rod. Beneficial effects

[0008] 1. By setting a central support arm and two side support arms, this utility model can simultaneously measure the exposed length of three anchor bolts, thereby improving measurement efficiency.

[0009] 2. This utility model uses a sliding plate and a scale rod to measure the exposed length of the anchor bolt by having the sliding plate rest on the end of the anchor bolt. The sliding plate is an Ω plate, and the scale on the upper surface of both sides of the sliding plate is the exposed length of the anchor bolt, which can be read directly.

[0015] Referring to Figures 1-2 A fan foundation prestressed anchor bolt exposed length measuring device, its composition includes middle branch 4 and two side branches, the middle branch with two the side branch is fixed through bolt, the gap 3 is set up in the middle branch, two side branches are divided into left branch 2 and right branch 5, bolt passes through the round hole on left branch and right branch, then passes through the gap of middle branch and is connected with nut thread, the end of the middle branch and the side branch is provided with wear ring 1 respectively, two scale rods 6 are fixed on the wear ring, the scale rod has scale, the scale gradually increases from bottom to top, sliding plate 7 passes through the scale rod and is slidably connected with the scale rod.

[0016] The sliding plate is Ω plate.

[0017] The scale rod is cylindrical scale rod.

[0018] Working principle: referring to Figures 3-4 , first, adjust the position of two side branches and a middle branch according to the position of anchor bolt, loosen the nut, rotate left branch and right branch, then slide left branch and right branch, make the wear ring of middle branch, left branch and right branch all pass through anchor bolt, tighten the nut after adjusting the position, then place the device on anchor plate, make the scale rod of device fall on anchor plate, anchor bolt passes through wear ring, at this time, anchor bolt will top the sliding plate and lift the sliding plate, because the sliding plate is Ω plate, the height of upper surface of both ends of sliding plate is consistent with the height of lower surface of middle part of sliding plate, so anchor bolt is topped on the lower surface of middle part of sliding plate, at this time, the height of lower surface of middle part of sliding plate is the height of anchor bolt, at the same time, the height of upper surface of both ends of sliding plate is consistent with the height of lower surface of middle part of sliding plate, so the exposed length of anchor bolt can be directly read out by reading the height of upper surface of both ends of sliding plate, so the exposed length of three anchor bolts can be directly read out by one middle branch and two side branches at one time, after reading, measure other anchor bolts, because anchor plate is circular and anchor bolts are arranged in circular array, so the nut does not need to be loosened to adjust the angle and position of two side branches, the device can be directly taken and placed on anchor bolts at other positions to measure the anchor bolts at other positions.
