Abstract
The invention discloses a hydraulic locking device of a vertical shaft hybrid lifting system, which comprises 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), wherein 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 hydraulic pipelines, 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 hydraulic pipelines. The hydraulic locking device for the vertical shaft hybrid lifting system can ensure stable locking between two sets of lifting systems, and further ensure safe and reliable operation of the lifting systems.
Description
Technical Field
The invention relates to a locking device, in particular to a hydraulic control locking device 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 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 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.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, this vertical shaft hybrid hoisting system hydraulic locking device includes cage hoisting winch hydraulic station 1, skip normally open brake disc 2, skip normally closed brake disc 3, skip hoisting winch hydraulic station 4, cage normally open brake disc 5, cage normally closed brake disc 6, cage hoisting winch hydraulic station 1 is connected with skip normally open brake disc 2 and cage normally closed brake disc 6 simultaneously through hydraulic pipeline, skip hoisting winch hydraulic station 4 is connected with skip normally closed brake disc 3 and cage normally open brake disc 5 simultaneously through 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 a bidirectional clamping structure.
The skip normally-opened brake disc 2, the skip normally-closed brake disc 3, the cage normally-opened brake disc 5 and the cage normally-closed brake disc 6 are all butterfly friction disc structures.
Cage hoisting winch hydraulic pressure station 1 provides pressure oil to cage normally closed brake disc 6, skip normally open brake disc 2 and makes cage normally closed brake disc 6 open when cage hoisting winch operates, and skip normally open brake disc 2 closes, and cage hoisting winch can operate this moment, and skip hoisting winch can not operate. When the skip hoisting winch operates, the skip hoisting winch hydraulic station 4 provides pressure oil to the skip normally closed brake disc 3 and the cage normally closed brake disc 6 to open the skip normally closed brake disc 3, the cage normally closed brake disc 6 is closed, the skip hoisting winch can operate at the moment, and the cage hoisting winch cannot operate.
