Laser type mark point measurement and paying-off instrument for electric power engineering

Abstract

The invention discloses a laser type mark point measurement and paying-off instrument for electric power engineering. The laser type mark point measurement and paying-off instrument includes a laser generator, a miniature sliding staff, a rotary disk, and a triangular claw disk; the laser generator is disposed on a top end of the miniature sliding staff; the rotary disk is disposed under the miniature sliding staff; a first water level and a second water level perpendicular to each other are disposed on the rotary disk; the rotary disk is disposed on the triangular claw disk; the rotary disk can rotate freely relative to the triangular claw disk; and three triangular claws distributed at an angle of 120 DEG are disposed under the triangular claw disk. Compared with the existing measurementinstrument and measurement and paying-off method, the laser type mark point measurement and paying-off instrument for the electric power engineering provided by the invention has the advantages thata manpower is saved, and only two people needs; a pen is used to scribe on a laser point irradiated by a laser beam, the measurement, reading, computation and marking on each measurement point turn out to be unnecessary, the instrument is like a common "wooden ruler" and complex measurement and paying-off work can be completed by means of comparison, so that the measurement and paying-off efficiency is high; the instrument provided by the invention is simple in structure, and does not have measurement and reading systems and a leveling mechanism to obtain a low cost; the instrument is particularly applied to a measurement and paying-off task of which the requirement on a measurement and paying-off precision is not high and numerous mark points with a same elevation are provided; and the instrument provided by the invention has wide and numerous applications.

Description

technical field [0001] The invention relates to a tool for measuring, setting out and marking several punctuation points of the same elevation in the construction process of electric power engineering, in particular to a laser type punctuation measuring instrument for electric power engineering. Background technique [0002] In the process of power engineering construction, it is often necessary to measure and release several punctuation points with the same elevation. For example, in pile foundation engineering, the pile head (or the pile body higher than the design elevation) Remove it to meet the design requirements, and the design elevation of each pile is generally the same (or several piles under the same foundation are the same), and the measurement and release of the interception position often requires multiple people. It is labor-intensive and inefficient to measure and mark each pile with the cooperation of a professional level and a tower ruler; another example i...

It is labor-intensive and inefficient to measure and mark each pile with the cooperation of a professional level and a tower ruler; another example is the leveling of the construction site, the measurement and marking of marking points at the same elevation, the excavation of the earth, and the leveling of the pile of earth And the process of measuring and releasing of slope, leveling of road engineering construction and measuring and releasing of side slope, related leveling of water conservancy project and measuring and releasing of side slope, etc., is also the same, labor-intensive, laborious and inefficient
