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 device for a vertical shaft hybrid lifting system, which can ensure stable locking between two sets of lifting systems, thereby ensuring safe and reliable operation of the lifting systems.
For realizing above-mentioned purpose, this mixed hoisting system hydraulic pressure blocking device of vertical includes that cage promotes winch hydraulic pressure station, skip normally open brake disc, skip normally closed brake disc, skip promotes winch hydraulic pressure station, cage normally open brake disc, cage normally closed brake disc, cage promotes winch hydraulic pressure station and is connected with skip normally open brake disc and cage normally closed brake disc simultaneously through hydraulic line, and skip promotes winch hydraulic pressure station and is connected with skip normally closed brake disc and cage normally open brake disc simultaneously through hydraulic line.
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 part and the electric locking part of the double-acting locking device of the vertical shaft hybrid lifting system simultaneously control only one of the cage lifting winch and the skip lifting winch to lift at the same time, and one of the hydraulic locking part and the electric locking part can only lift one of the winches at the same time under the condition that one of the hydraulic locking part and the electric locking part is out of order, so that stable locking between two sets of lifting systems can be ensured, and the safe and reliable operation of the lifting systems is further ensured.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
The double-acting locking device of the vertical shaft hybrid lifting system comprises a hydraulic locking part and an electric locking part.
As shown in fig. 1, the hydraulic locking portion includes a cage lifting winch hydraulic station 1, a skip normally-open brake disc 2, a skip normally-closed brake disc 3, a skip lifting winch hydraulic station 4, a cage normally-open brake disc 5, and a cage normally-closed brake disc 6, the cage lifting winch hydraulic station 1 is simultaneously connected with the skip normally-open brake disc 2 and the cage normally-closed brake disc 6 through a hydraulic pipeline, and the skip lifting winch hydraulic station 4 is simultaneously connected with the skip normally-closed brake disc 3 and the cage normally-open brake disc 5 through a hydraulic pipeline. The skip normally-open brake disc 2, the skip normally-closed brake disc 3, the cage normally-open brake disc 5 and the cage normally-closed brake disc 6 are all of bidirectional clamping structures.
