Description
Technical Field
The invention relates to a locking control method, in particular to a hydraulic control locking method suitable for controlling a lifting cage lifting winch and a skip lifting winch of a hybrid well, and belongs to the technical field of safety protection of lifting systems.
Background
With the steady development of national economy, the national economy has more and more demands on energy. Coal mines are still the main energy structure in China, and coal accounts for about 70% of primary energy consumption. At present, in mine construction, the construction of a vertical shaft mine with an ultra-large diameter and a deep depth becomes the trend of mine construction. Two sets of lifting systems are adopted in the same shaft more and more, wherein one set of lifting system is lifted by a cage, and the other set of lifting system is lifted by a skip.
Adopt two sets of lift systems can bring a problem, if cause the lift accident easily when two sets of lift systems lift simultaneously, so adopt two sets of lift systems' needs to guarantee that only one set of lift system works at the same time at present, generally adopt the software mode of shutting to shutting between two sets of lift systems, adopt the software mode of shutting, cause the shutting to be malfunctioning easily when PLC operation goes out the problem, and then can cause the promotion incident.
Disclosure of Invention
Aiming at the problems, the invention provides a hydraulic locking control method for a vertical shaft hybrid lifting system, which can ensure stable locking between two sets of lifting systems and further ensure safe and reliable operation of the lifting systems.
In order to achieve the purpose, the hydraulic locking device of the vertical shaft hybrid hoisting system comprises a cage hoisting winch hydraulic station, a skip normally-open brake disc, a skip normally-closed brake disc, a skip hoisting winch hydraulic station, a cage normally-open brake disc and a cage normally-closed brake disc, wherein the cage hoisting winch hydraulic station is simultaneously connected with the skip normally-open brake disc and the cage normally-closed brake disc through hydraulic pipelines, and the skip hoisting winch hydraulic station is simultaneously connected with the skip normally-closed brake disc and the cage normally-open brake disc through hydraulic pipelines;
when the cage hoisting winch operates, the cage hoisting winch hydraulic station provides pressure oil to the cage normally closed brake disc and the skip normally open brake disc to open the cage normally closed brake disc and close the skip normally open brake disc, at the moment, the cage hoisting winch can operate, and the skip hoisting winch cannot operate; when the skip hoisting winch operates, the skip hoisting winch hydraulic station provides pressure oil to the skip normally closed brake disc and the cage normally closed brake disc to enable the skip normally closed brake disc to be opened, the cage normally closed brake disc is closed, the skip hoisting winch can operate at the moment, and the cage hoisting winch cannot operate.
As a further improvement scheme of the invention, the skip normally-open brake disc, the skip normally-closed brake disc, the cage normally-open brake disc and the cage normally-closed brake disc are all bidirectional clamping structures.
As a further improvement scheme of the invention, the skip normally-open brake disc, the skip normally-closed brake disc, the cage normally-open brake disc and the cage normally-closed brake disc are all butterfly friction disc structures.
Compared with the prior art, the hydraulic locking device of the vertical shaft hybrid lifting system and the original PLC software control system simultaneously control the cage lifting winch and the skip lifting winch to be lifted only by one at the same time, the hydraulic locking device of the vertical shaft hybrid lifting system and the original PLC software control system can only lift one winch at the same time under the condition that one of the hydraulic locking device of the vertical shaft hybrid lifting system and the original PLC software control system is out of order, stable locking between two sets of lifting systems can be ensured, and the lifting systems can be further ensured to run safely and reliably.
