Laser longitude and latitude multifunctional fast arc-measuring apparatus as well as measuring and calculating method thereof

Abstract

The invention discloses a laser longitude and latitude multifunctional fast arc-measuring apparatus as well as a measuring and calculating method thereof for measuring arc on the main girder of a bridge crane. The arc-measuring apparatus consists of a commonly used microtubular laser distance meter and a theodolite; the microtubular laser distance meter is permanently fixed on the drawtube shell of an optical theodolite or an electronic theodolite with a special processing technology; and the tubular axial center line of the microtubular laser distance meter is parallel to the drawtube axial center line of the theodolite. A calculator is further arranged on the arc-measuring apparatus, wherein, the measuring method measures the slant range, the elevation angle and the horizontal angle of three object measuring points which are arranged at two edges and one center on the main girder of the bridge crane at the same position with the arc-measuring apparatus so as to calculate the arc on the main girder. The arc-measuring apparatus has the advantages that structure is compact, apparatus is light and flexible, measuring crew does not need to assemble and adjust each component on the spot, operation is simple and convenient, and measuring precision and efficiency is high; and the arc-measuring apparatus can be widely applied to other measuring fields.

Description

technical field [0001] The invention relates to a measuring device and a measurement and calculation method for the camber of the main girder of a bridge crane, in particular to a laser latitude and longitude multi-function rapid measurement for measuring the distance and angle and then quickly completing the camber measurement of the main girder of a bridge crane Arch meter and its measurement calculation method. Background technique [0002] For a long time in the past, relevant departments such as crane manufacturing and installation and special equipment inspection have basically used the steel wire drawing method to measure the camber of the main girder of bridge cranes. However, this method of arch measurement has several disadvantages: ① It is dangerous to operate this method on a high bridge frame; ② This method cannot measure the camber of the single-girder bridge crane in use at all; ③ This method is cumbersome to operate, and the steel wire is easy to hurt hands;...

Problems solved by technology

However, this method of arch measurement has several disadvantages: ① It is dangerous to operate this method on a high bridge frame; ② This method cannot measure the camber of the single-girder bridge crane in use at all; ③ This method is cumbersome to operate, and the steel wire is easy to hurt hands; ④ the detection instrument of this method is heavy and dull, and it is very inconvenient to carry it on the machine; Calculations are performed manually, which is labor-intensive and time-consuming.

Although these emerging measuring instruments have many characteristics in use, they are not special instruments specially designed for arch measurement, so there are also many inconveniences in using these instruments to measure arches: a single electronic theodolite cannot measure arches. Although the so-called total station can measure the camber through a set of special operations, it has the trouble of assembling and adjusting multiple components on site, and the range finder must be re-adjusted before measuring each measuring point. The trouble that the horizontal axis is parallel to the horizontal axis of the theodolite lens barrel is inconvenient to operate, and the technical requirements are high. The average person may not be able to assemble and adjust the field in a short period of time. In addition, although the measurement data can be automatically input into the electronic manual, it still needs to be Manually calculate each measurement point one by one and then combine them to get the measurement results, so there is no report on using it directly for rapid arch measurement.
