Embodiment

[0052] The following are specific examples of technical solutions of the present invention.

[0053] In this example, when monitoring the life of the crane wire rope, the following steps are used:

[0054]Step 1, according to the different weight of n weight grades, each weight class corresponds to a count value of 0 initial value, and each weight class is preset corresponding to the load factor, the larger the weight corresponding to the weight class, the larger the load factor corresponding to the weight class, set: A i Is the count value corresponding to the ith weight class, B i is the load factor corresponding to the i weight class, where i is a positive integer, n is a positive integer, 1≤i≤n, n≥2.

[0055] Step 2: When lifting goods, the crane obtains the weight of the lifted goods through the weighing device and sends the weight of the lifted goods to the calculation and processing equipment; Among them, the load changes from 0 to non-0, and then from non-0 to 0 when it is...

Abstract

The invention relates to a crane wire rope safety monitoring technology, which solves the problems of inaccurate evaluation results of the existing crane wire rope life evaluation method, resulting in cost waste and low crane operation safety. The technical solution is summarized as follows: every time the goods are hoisted, the weight of the hoisted goods is detected, and according to the pre-divided weight classes, the number of hoisting times under each weight class is counted separately, and each weight class corresponds to a different load factor , and then combine the lifting times and load factors corresponding to each weight class to calculate the service life of the wire rope, and then obtain the remaining life of the wire rope. The beneficial effect is that the present invention combines the actual operation conditions of the steel wire rope when calculating the remaining life of the steel wire rope, which greatly reduces the problems of over-maintenance and under-maintenance of the steel wire rope, makes the crane work with high safety, and reduces the cost and waste of steel wire rope maintenance. The invention is especially suitable for the life monitoring system of the steel wire rope of the crane.

Description

Technical field [0001] The present invention relates to crane wire rope safety monitoring technology, particularly to crane wire rope life monitoring technology. Background [0002] Prior art in the crane wire rope service life is in accordance with the fixed replacement cycle and / or manual inspection of the management mode to determine, this mode can not be combined with the actual operation of the crane to assess the service life of the wire rope, so that the wire rope life assessment results are not accurate, will inevitably bring the wire rope over maintenance or under-maintenance problems, wire rope over maintenance leads to cost waste, under-maintenance leads to low safety of crane operations. Contents of the Invention [0003] The present invention to solve the existing crane wire rope life assessment method evaluation results are inaccurate, resulting in cost waste and low safety of crane operation, to provide a crane wire rope life monitoring method. [0004] To solve...
