Embodiment Construction

[0015] like figure 1 As shown, the measuring device of the present invention is made up of profiled steel gantry 3, steel wire 6, wire tensioner 4, portable electronic scale 5, steel tape measure 7, conical inspection head 1; The two ends of the wire 6 are respectively connected to the two steel gantry frames 3, one end of the steel wire 6 is connected with a steel tape measure 7, and the other end of the steel wire 6 is connected with a portable electronic scale 5 and a wire tensioner 4 (the two ends of the steel wire pass through The wire tensioner 4 is fixed on the section steel gantry frame 3), and a conical inspection head 1 is housed on the measured anchor bolt.

[0016] The measurement method is: Find and mark the cross center point of a single foundation, hang steel wire 6 along the two opposite corners of the rectangle formed by connecting the four adjacent foundation centers, so that the steel wire passes through the cross center point of a single foundation. For t...

Abstract

The invention discloses a measurement method for the mounting and positioning of basic direct-buried foundation bolts of large-scale equipment, comprising the steps of finding and marking cross central points of single basic direct-buried foundation bolts and measuring the lengths of two diagonal lines of a rectangle formed by lines of centers of four adjacent basic direct-buried foundation bolts. A used measurement device consists of two structural steel door-shaped frames, a steel wire, a wire grip, a portable electronic scale, a steel tape and a conical check head, wherein two ends of the steel wire are respectively connected onto the two structural steel door-shaped frames; one end of the steel wire is connected with the steel tape and the other end of the steel wire is connected with the portable electronic scale and the wire grip; and the conical check head is arranged on the measured foundation bolt. The method is used for measuring the mounting and positioning precisions of the basic direct-buried foundation bolts of the large-scale equipment and has the advantages of being simple in operation and improving the construction efficiency and the mounting precision.

Description

Technical field [0001] The invention involves the field of thermal power engineering technology, and it is specifically a large -scale equipment foundation of armal power plant. Background technique [0002] At present, the large -scale equipment foundation of the armal power plant is directly buried and the foot bolt installation and positioning measurement is used to control the "small cross" method, which is based on the central cross line of the entire equipment foundation to detect the central cross line of a single foundation., Based on the central cross line of a single basis, the foundation of the foundation of the basis is to detect the positioning accuracy of the direct buried foot bolt.This method is used for the installation and positioning measurement of direct buried foot bolts, which is difficult to ensure that the positioning accuracy of the installation of direct buried foot bolts achieves the accuracy of the design requirements. Invention content [0003] The p...
