Device for preventing skip bucket from repeatedly coaling

Abstract

The invention discloses a device for preventing a skip bucket from repeatedly coaling. The device comprises a main well winch lifting steel wire rope (1), a lifting skip bucket (2), a winch electric control system (8), a signal system garage display device (9), a signal system management control device (10) and a sensor (6) which is mounted above the lifting skip bucket for measuring coal storage in the skip bucket; the sensor is connected with the winch electric control system, the signal system garage display device and the signal system management control device; the winch electric control system is used for controlling the skip bucket to work according to the coal storage, detected by the sensor, in the lifting skip bucket. The device utilizes the sensor to measure the coal storage in the ship bucket, and is combined with the signal system and the winch electric control system, so that winch operation is stopped when abnormity appears, and alarming and monitoring are accurate, stable and reliable, and therefore, the device is suitable for lifting a vertical shaft gate side-dumping type skip bucket, and effectively prevents serious damages, caused by repeated coaling of the skip bucket, to a mine.

Description

technical field [0001] The invention relates to a device for preventing repeated coal loading in a skip, and belongs to the technical field of raw coal lifting in coal mines. Background technique [0002] At present, in the process of lifting raw coal in the main shaft of the coal mine, the coal is generally transported by using a skip, and the skip will deliver the fully loaded coal to the destination for unloading before the next transportation. Whether the coal in the skip is completely unloaded directly affects the quality and safety of the entire raw coal lifting. If the coal in the skip is not completely unloaded, if the coal in the skip is not completely unloaded, it will cause the winch to be overloaded, stop, and the processing process is dangerous and time-consuming. Long, which seriously affects the lifting time of raw coal; if it is serious, it will cause a tank drop accident, cause serious damage to shaft equipment and hoisting equipment, and cause immeasurable ...

Whether the coal in the skip is completely unloaded directly affects the quality and safety of the entire raw coal lifting. If the coal in the skip is not completely unloaded, if the coal in the skip is not completely unloaded, it will cause the winch to be overloaded, stop, and the processing process is dangerous and time-consuming. Long, which seriously affects the lifting time of raw coal; if it is serious, it will cause a tank drop accident, cause serious damage to shaft equipment and hoisting equipment, and cause immeasurable losses to the mine.
