Embodiment

[0052] The technical scheme of the present invention is illustrated in detail below.

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

[0054] Step 1. Divide n weight classes according to different weights. Each weight class corresponds to a count value with an initial value of 0, and preset the corresponding load factor for each weight class. The greater the weight corresponding to the weight class, Then the load factor corresponding to the weight class is also larger, assuming: A i is the count value corresponding to the i-th weight class, B i is the load factor corresponding to the i-th weight class, where i is a positive integer, n is a positive integer, 1≤i≤n, n≥2.

[0055] Step 2. When hoisting goods, the crane obtains the weight of the hoisted goods through the weighing device, and sends the weight of the hoisted goods to the calculation and processing equipment; wherein, the load changes from 0 to non-zero, a...

Abstract

The invention relates to a crane steel wire rope safety monitoring technology, and solves the problems of cost waste and low crane operation safety caused by inaccurate evaluation results of an existing crane steel wire rope service life evaluation method. The technical scheme is summarized as follows: when goods are hoisted each time, detecting the weight of lifted goods when a steel wire rope is lifted, respectively counting the number of times of lifting under each weight level according to pre-divided weight levels, calculating the service life of the steel wire rope by combining the number of times of lifting corresponding to each weight level and the load coefficient, and further obtaining the remaining life of the steel wire rope. The method has the beneficial effects that when theremaining service life of the steel wire rope is calculated, the actual operation condition of the steel wire rope is combined, the problems of over-maintenance and under-maintenance of the steel wire rope are greatly reduced, the safety is high during crane operation, and the cost waste of steel wire rope maintenance is reduced. The method is particularly suitable for crane steel wire rope service life monitoring systems.

Description

technical field [0001] The invention relates to the safety monitoring technology of the steel wire rope of the crane, in particular to the life monitoring technology of the steel wire rope of the crane. Background technique [0002] In the prior art, the service life of steel wire ropes of cranes is judged according to the management mode of fixed replacement cycle and / or manual spot inspection. This mode cannot be combined with the actual operation conditions of the crane to evaluate the service life of steel wire ropes, making the life evaluation results of steel wire ropes inaccurate. It will inevitably lead to the problem of over-maintenance or under-maintenance of the steel wire rope. Over-maintenance of the steel wire rope will lead to waste of cost, and under-maintenance will lead to low safety of the crane operation. Contents of the invention [0003] The invention provides a crane wire rope life monitoring method for solving the problems of inaccurate evaluation r...
