Unattended operation control system and method for mine vertical shaft hoist

Abstract

The invention relates to the field of mine hoists, in particular to an unattended operation control system and method for a main vertical shaft hoist. The unattended operation control system comprises a main machine system, an auxiliary machine system, a power distribution system, a transmission system, a PLC control system, a machine room monitoring table, a shaft mouth control table, a mine hoist depth indicator device, a system fault pushing system and an industrial audio and video monitoring system. The PLC control system is connected with the main machine system, the auxiliary machine system, the transmission system, the machine room monitoring table and the shaft mouth control table. The main machine system is connected with the transmission system through a cable. The transmission system is connected with the power distribution system. The shaft mouth control table is connected with the mine hoist depth indicator device. The machine room monitoring table is connected with the system fault pushing system and the industrial audio and video monitoring system. According to the unattended operation control system and method for the main vertical shaft hoist, the size of personnel force is reduced in a user vertical shaft lifting system, the labor cost is reduced, and meanwhile the possibility of misoperation of operators is lowered.

Description

technical field [0001] The invention relates to the field of mine hoists, in particular to an unattended control system and control method for a mine shaft hoist. Background technique [0002] Hoists are widely used in vertical shafts and inclined shafts of mines. They are mainly responsible for lifting minerals, lifting personnel, materials and equipment. They are the throat of mine system equipment. The safety and efficient operation of the hoist control system are crucial. Its technical performance and Reliability directly affects mine safety production and economic benefits. [0003] The new version of the National Coal Mine Safety Regulations will be released in October 2016. The safety regulations clearly introduce the concept of "unattended" (Article 428 (1) The operation of the hoist must comply with the following regulations: the main hoist The machine device should be equipped with a driver and a co-driver. The automatic operation of the skip hoist dedicated to li...

(2) The main lifting device for lifting personnel must be operated by the driver and supervised by the co-driver during the time when the lifting personnel are handed over.

[0005] 1. With the development of automation technology for mining electromechanical equipment, although automatic control has been realized, there are many human-involved controls (the operation instructions of the hoist in the original system were issued manually by the operating console in the machine room, see figure 1 ), has a certain impact on the safety, stability and economy of the hoist

[0006] 2. If the control system fails, the operator needs to call the maintenance personnel and the dispatch center to report the fault status. It is difficult for the dispatch center to understand the fault situation in a timely and accurate manner, resulting in delayed or unreasonable decision-making, which may bring losses to the enterprise

[0008] 4. Insufficient detection methods for the main parts of mechanical equipment, leaving many detection blind spots, unable to effectively protect mechanical equipment

[0009] 5. Part of the safety detection is mechanical detection, the detection accuracy is low, the serial communication method, the anti-interference ability is poor, and the communication is unreliable
