Fault detection method for bucket slack rope based on bucket running safety comprehensive protection system

Abstract

The invention discloses a bucket rope looseness fault detection method based on a comprehensive protection system of bucket running safety. The four main parts of an onboard detection sub-system, a wireless transmission sub-system, a ground protection sub-system and a remote monitoring sub-system are included; the onboard detection sub-system and the wireless transmission sub-system are connected and perform data transmission through a wireless network; the wireless transmission sub-system and the ground protection sub-system are connected and perform data transmission through an optical fiber cable; the ground protection sub-system and the remote monitoring sub-system are connected and perform data transmission through the Internet; and by means of the bucket rope looseness fault detection method, whether a rope looseness fault happens to a bucket or not can be directly detected by means of the real-time speed, posture and position in the bucket running process. By means of the system, ground operation personnel and remote management personnel can comprehensively know about various parameters of bucket running, an alarm can be given out at the early stage of an accident, essential protection measures are automatically taken, and therefore safe running of the bucket can be guaranteed comprehensively.

Description

technical field [0001] The invention relates to a safety protection technology for the operation of a hanging bucket, in particular to a method for detecting a slack rope fault of a hanging bucket based on a comprehensive protection system for the operation safety of the hanging bucket. Background technique [0002] Bucket lifting is the main transportation method for lifting personnel, gangue and materials during the construction of vertical shafts, and it occupies an irreplaceable core position in the construction of vertical shafts. Whether the bucket hoisting system can operate safely not only affects the wellbore construction efficiency, but also affects the life safety of workers and the economic interests of the enterprise. With the increase of construction projects year by year and the continuous shortening of the construction period, the task intensity of the lifting bucket is also increasing, and the resulting vicious accidents also continue to occur. The squattin...

AI Technical Summary

Problems solved by technology

[0006] After analyzing common bucket lifting accidents, it can be found that the root cause of the accident is that the ground lifting driver cannot accurately know whether the bucket is loose, which can easily lead to accidents and cause serious casualties and property losses

According to the domestic research status, it is found that there is currently no safety protection system specifically for bucket lifting during shaft construction

At present, the widely used anti-squat tank devices, anti-falling devices, and anti-rolling equipment are all "post-event protection", that is, how to reduce casualties after the accident has occurred. This "passive trigger" protection system cannot be applied to vertical wells. Complex and changeable on-site working environment during construction
