Problems solved by technology

[0002] At present, the girder camber measurement of large-scale equipment, such as the electric single girder and main girder of the crane, is mainly measured by a special arch tester (steel wire measurement method), using a wire rope and a tape measure or a level and a tape measure for measurement. At the same time, manual alignment an

Embodiment Construction

[0020] Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail:

[0021] The laser arch measuring instrument shown in Figure 1 is composed of a level 6, a data collector 4 and a computer processing system 1, the level is a laser automatic leveling level, and the data collector is a base 7 equipped with a light target 8 and a rangefinder 14, The data collector is connected with the computer processing system through the image transmission line 3 and the control data line 2 . Wherein the data collector includes a receiving light target 8, a rangefinder 14, a base 7 and a battery box 17 as shown in Figure 2, the base interface is a threaded sleeve structure, the base interface is threaded with the light target, and the light target is installed on the base, The top of the light target is equipped with a range finder. As shown in Figure 3, the light target includes a target surface cover 9, a blister 15, an image data lin...

Abstract

The invention relates to a camber admeasuring apparatus and a laser camber measuring method. After level gauge providing a level baseline, lighting target of data collector gathers its facula and sends the facula image to computer processing system. Based on the image, the computer calculates the vertical ordinate D of baseline on lighting target, data collector measures longitudinal separation H between measured point and itself simultaneously and sends it to the computer. Then the computer calculates longitudinal separation between measured point and level baseline. The invention adopts laser to measure intelligently, level gauge to provide baseline and high precision, data collector to complete laser ranging. Thus, camber admeasuring of lower flange can be completed on the ground. Computer deals with data directly to avoid manual interpretation, which achieves high accuracy, high efficiency and simple operation.

Description

Technical field: [0001] The invention relates to a crown measuring instrument, especially a laser arch measuring instrument. Background technique: [0002] At present, the girder camber measurement of large-scale equipment, such as the electric single girder and main girder of the crane, is mainly measured by a special arch tester (steel wire measurement method), using a wire rope and a tape measure or a level and a tape measure for measurement. At the same time, manual alignment and human eye interpretation, and due to the downward deflection caused by the self-weight of the steel wire, this method must consider the correction value, which is cumbersome, and there are many intermediate links in the measurement, which are greatly affected by human factors. The data has certain subjectivity and low precision. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a laser arch measurement method, which is simple, h...
