A comprehensive protection system and protection method for bucket operation safety

Abstract

The invention discloses a lifting barrel operation safety comprehensive protection system and a protection method thereof. The system comprises an onboard detecting subsystem, a wireless transmission subsystem, a ground protection subsystem and a remote monitoring subsystem connected in sequence. Meanwhile, the invention further discloses a monitoring method of lifting barrel lifting process motion parameters based on the lifting barrel operation safety comprehensive protection system, an obstacle detecting method and a rope looseness fault direct detecting method for obtaining real-time speed, posture and position of a lifting barrel in the operation process, actively detecting the conditions of an obstacle below the lifting barrel and directly detecting if the lifting barrel generates the rope looseness fault. The system can enable ground operators and remote managers to comprehensively master all operation parameters of the lifting barrel, can give an alarm at the beginning of accidents, and automatically adopts necessary protection measures to comprehensively guarantee safe operation of the lifting barrel.

Description

technical field [0001] The invention relates to a bucket running safety protection technology, in particular to a bucket running safety comprehensive protection system and a protection method thereof. Background technique [0002] Bucket lifting is the main transportation mode for lifting personnel, gangue and materials during the construction of the shaft shaft, and occupies an irreplaceable core position in the construction process of the shaft shaft. Whether the bucket lifting system can operate safely not only affects the efficiency of wellbore construction, but also relates to the safety of workers and the economic interests of enterprises. With the increasing number of construction projects and the continuous shortening of the construction period, the task intensity of bucket lifting is also increasing, and the resulting vicious accidents continue to occur, such as loose ropes and Squat tank accidents, drowning accidents caused by the deep water in the well bottom, an...

AI Technical Summary

Problems solved by technology

[0006] After analyzing the common bucket lifting accidents, it can be found that the root cause of the accident is that the ground lifting driver cannot accurately know the surrounding environment during the lowering of the bucket, especially when there are people or foreign objects suddenly appearing under the bucket, the ground driver cannot find it in time. , eventually leading to accidents and 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
