Problems solved by technology

[0005] The traditional method for the web warpage of the main girder of the crane has low precision, low contrast, and poor safety; the theodolite can be used to directly measure the deflection of the main girder, but it is difficult to detect the web warpage of the main girder; the total station The detection of the main beam can detect multiple parameters at the same time, but the cost of the instrument is high and the operation is complicated, which requires professionals to operate; the method of using the laser rangefinder is easy to operate, but it requires manual operations at the same time, and the degree of automation is not high. high

Abstract

The invention relates to an automatic device for detecting warping degree of a main beam web of a crane and a detection method, and belongs to the technical field of crane detection. The automatic device for detecting the warping degree of the main beam web of the crane comprises a laser emission module, a light target platform and an intelligent terminal playing a control role, the laser emissionmodule is fixedly arranged on a main beam web plate, and the light target platform is installed on the main beam web plate and moves along the main beam web plate; the light target platform comprisesa moving trolley, a control part used for controlling the moving trolley and a light target installed on the moving trolley; and the laser emission module comprises a laser emitter, and laser beams emitted by the laser emitter irradiate the light target. The warping degree of the main beam web plate is detected by establishing a crane main beam web plate space coordinate system, and the detectionprecision is more accurate.

Description

technical field [0001] The invention relates to an automatic device and a detection method for detecting the warpage of a main girder web of a crane, and belongs to the technical field of crane detection. Background technique [0002] With the development of the economy, cranes have become one of the most widely used special equipment, playing an important role in industries such as machinery manufacturing, metal smelting and port transportation. Due to the special working environment of the crane, during its operation and use, some key parts such as the main girder bear large loads and are prone to overload and deformation. If they cannot be detected and dealt with in time, it is easy to cause safety accidents and bring serious Loss of life and property. [0003] The safety monitoring of the crane includes many aspects, among which the parameter detection of the main girder structure is the most critical. The main girder web is one of its main structures, and its warpage ...
