A high-altitude deflection measuring device for I-shaped large plate beams

Abstract

The invention discloses a high-altitude deflection measuring device for an I-shaped main girder. The device structurally comprises a position adjusting structure, squares, a measuring structure and aheavy hammer balancer, wherein the position adjusting structure is horizontally arranged on the two sides of the measuring structure; two squares are perpendicularly welded to the bottom surface of the measuring structure; the heavy hammer balancer is vertically arranged at a position, close to a central axis of the measuring structure, of the measuring structure; and the heavy hammer balancer ismovably attached to the right-angle sides of the squares. The position adjusting structure, the squares, the measuring structure and the like are matched, so that the position adjusting structure canbe fixed at a high altitude without building a supporting frame, whether the position adjusting structure is parallel can be horizontally calibrated on the ground and the height of each side face of the main girder can be observed and recorded visually, the measuring structure can also horizontally move at the high altitude, multi-point measurement can be carried out, most of data can be obtained,and the maximum deflection of the main girder can be obtained.

Description

technical field [0001] The invention relates to the field of high-altitude operations, in particular to a high-altitude deflection measuring device for an I-shaped large plate girder. Background technique [0002] Generally, factories that use boilers to convert heat will install an air preheater in the tail flue of the boiler. The air preheater is installed in the tail flue, that is, the high altitude area, and will be fixed with a large plate beam. Large, the deformation speed of a single plate girder is generally faster, and the I-shaped plate girder will have a better pressure bearing capacity, but deformation will also occur. The traditional method of deflection measurement at high altitude requires measures such as erecting steel wires, and multi-point measurement When improving data accuracy, it is necessary to continuously disassemble and assemble, and the process is cumbersome. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the pr...
