Abstract

The invention provides a crane main beam camber measuring device and method. The crane main beam camber measuring device comprises a supporting assembly, a lead screw rod, an operation assembly, a horizontal laser ranging assembly and a vertical laser ranging assembly, wherein the supporting assembly is disposed on a horizontal part of a crane main beam; the lead screw rod is arranged on the supporting assembly; the operation assembly is arranged on the lead screw rod, and the operation assembly can ascend or descend along the lead screw rod; the horizontal laser ranging assembly is arranged on the operation assembly, and the horizontal laser ranging assembly is used for measuring the distance between the horizontal laser ranging assembly and the upper arch part of the crane main beam in the horizontal direction; and the vertical laser ranging assembly is arranged on the operation assembly, and the vertical laser ranging assembly is used for measuring the distance between the verticallaser ranging assembly and the horizontal part of the crane main beam in the vertical direction. According to the crane main beam camber measuring device and the method provided by the invention, themeasurement efficiency and precision of the camber on a crane girder can be improved.

Description

technical field [0001] The invention relates to a deformation measurement system for special equipment, in particular to a device and method for measuring camber on the main girder of a crane. Background technique [0002] The main girder is the main load-bearing component of the crane. Strength, stiffness and stability are important indicators for evaluating the working performance of the crane. Camber is one of the key parameters for evaluating its stiffness performance. The test result of the camber directly affects the performance of the crane. Performance and lifespan. [0003] At present, the common method for measuring the camber of the main girder of the crane is the steel wire drawing method. The method is as follows: first, select a steel wire with a certain diameter, and the inspector straightens the steel wire on the main girder, and one end of the steel wire is fixed on the steel wire fixing wheel at one end of the main girder. The other end of the steel wire g...
