Embodiment 1

[0031] Taking a portal crane as an example, the method for acquiring crane measured load spectrum data, the crane measured load spectrum data acquisition system, and the crane remaining fatigue life evaluation system based on the crane's measured load spectrum data are described below by taking a portal crane as an example.

[0032] Firstly, the system for acquiring the actually measured load spectrum data of the crane in this embodiment will be described. like figure 1As shown, the system includes a data acquisition device 10 , a data processing device 20 and a display device 30 . Wherein, the data acquisition device 10 includes a lifting height sensor 101 , an amplitude sensor 102 and a lifting weight sensor 103 . Each data sensor transmits the collected lifting height data, amplitude data, lifting weight data, etc. to the data processing device 20 via the isolation filter circuit 40 . Include working condition detecting device 201 in the data processing device 20, and it ...

Embodiment 2

[0048] In the following, a gantry crane is taken as an example to illustrate the crane's measured load spectrum data acquisition method, the crane's measured load spectrum data acquisition system and the crane's remaining fatigue life evaluation system based on the crane's measured load spectrum data. Components with the same or similar functions and structures as those in Embodiment 1 are assigned the same numbers, and repeated descriptions are omitted.

[0049] like Figure 4 As shown, the crane measured load spectrum data acquisition system in this embodiment includes a data acquisition device 10 , a data processing device 20 and a display device 30 . Wherein, the data acquisition device 10 includes a lifting height sensor 101 , a displacement sensor 104 and a lifting weight sensor 103 . Each data sensor transmits the collected lifting height data, displacement data, lifting weight data, etc. to the data processing device 20 via the isolation filter circuit 40 . Include w...

Abstract

The invention relates to a crane load spectrum data acquisition system. The crane load spectrum data acquisition system comprises a data acquisition device, a data processing device and a display device, wherein the data acquisition device acquires the condition data of a crane; the data processing device is used for receiving the condition data from the data acquisition device, and selects and stores the condition data respectively; and the display device is used for displaying the condition data according to user requests. Actually measured load spectrum data of the crane can be obtained through applying the above technical scheme in the invention, so the assessment is accurate. The invention also relates to a crane load spectrum data acquisition method and a fatigue life assessment system.

Description

technical field [0001] The invention relates to the field of crane residual fatigue life evaluation, in particular to a crane load spectrum data acquisition method, a crane load spectrum data acquisition system and a crane residual fatigue life evaluation system based on the crane's actually measured load spectrum data. Background technique [0002] Hoisting machinery is an indispensable and important equipment in petrochemical, metallurgy, construction, water conservancy and electric power, ports, machinery and other industries. These devices are expensive, require a long time to manufacture, install, and debug, use and maintain high costs, and are complicated to manage. There is no standard for the replacement and scrapping time of the equipment. Most of the existing equipment in the enterprise has been in service for many years, and the prediction of their service life or limit state is a problem that enterprises are very concerned about and need to solve urgently. There...
