Embodiment Construction

[0034] In the prior art, the safety analysis for quayside container cranes is mainly force analysis, and it is impossible to comprehensively evaluate the structural integrity of quayside container cranes.

[0035] In order to solve the above problems, the present invention provides a safety assessment method for shore container cranes, including:

[0036] Carry out wall thickness testing on the main stress-bearing structural parts to determine the corrosion state of the main stress-bearing structural parts;

[0037] Acceleration measurement of shore container cranes, and vibration analysis of main stressed structural parts;

[0038] Rail gnawing analysis is carried out through the geometrical tolerance detection of the main parameters;

[0039] Carry out defect detection on the main stressed structural parts;

[0040] Carry out standard inspections on lifting mechanisms, traveling mechanisms, electrical systems and safety protection devices;

[0041] Conduct dynamic and sta...

Abstract

The invention provides a safety assessment method and a safety assessment device for a quayside container crane. The safety assessment method includes that a wall thickness detection is conducted on main stressed structural members; an acceleration measurement of the quayside container crane is conducted, and vibration characteristic analysis is conducted on the main stressed structural members; rail gnawing analysis is conducted through detecting major parameter form and location tolerance; a defect detection is conducted on the main stressed structural members; standard detections are conducted on a hoisting mechanism, a travelling mechanism, an electrical system and a safety device; a dynamic stress test, a static stress test and virtual simulation analysis are conducted to confirm strength characteristics of the main stressed structural members; a complete machine fatigue life model is established; a remaining life prediction of the complete machine is conducted based on the fatigue life model; an assessment result of the quayside container crane is determined based on the wall thickness detection, the vibration analysis, the rail gnawing analysis, the defect detection, the standard detections, strength characteristic analysis, and fatigue life analysis. A comprehensive safety and life evaluation is conducted on the quayside container crane.

Description

technical field [0001] The invention relates to a safety evaluation technology of a metal structure, in particular to a safety evaluation method and a safety evaluation device of a shoreside container crane. Background technique [0002] In order to ensure the safe operation of quayside container cranes and reduce safety accidents, it is necessary to take measures to carry out safety inspections on quayside container cranes. In the invention patent application with the patent application number CN201310276709.X, a tower crane safety assessment method is disclosed. The main ideas and steps are as follows: 1. Perform force analysis on the stressed structure of the tower crane; 2. According to the steps 1. Determine the safety assessment detection point of the metal structure of the tower crane by analyzing the results; 3. Install sensors on the safety assessment detection point; 4. Collect sensor information on each safety assessment detection point through the data acquisitio...
