Common Faults and Countermeasures of Scraper Conveyor in Coal Mine

I. Comprehensive problems and countermeasures of scraper conveyor

1. Facility problems: Comprehensive control analysis of possible problems in the scraper conveyor, and strategic production control according to the production equipment.

2. Reasonable control of the scraper bolt: During the process of troubleshooting, the actual height of the scraper transporter and the need to use the groove structure, while satisfying the basic production, should also control the degree of wear, which can be combined with actual production. The demand is to carry out comprehensive control, and regulate the transportation effect of various aspects such as the position of the coal fall and the operation direction, and adjust it.

3, the problem of accuracy, span structure: the local control of the scraper chain skipping fault, can be combined with the actual position of the abnormal structure to control and coordinate, through the coordinated control, complete the problems of precision and span structure.

4. There is a problem with the link position due to the crowbar: For the adjustment of the facility supply, it can be adjusted according to the scope of the scraper transportation to realize the pre-treatment of possible threats and complete the supervision control.

5, electric start-up process problem: winding electronic and operating electric machinery in actual use, if there is a problem, it may affect the operation of the facility, affect the heating effect of the motor, pose a threat to safety, and the voltage operation of the power supply may also affect the voltage at the power station. The capacity and motor start-up operation are affected by the frequency of use.

Second, specific faults and treatment measures

malfunction:

1. The manufacturing quality of the scraper material does not meet the production requirements;

2. The working surface is not flat enough, which causes the scraper to scratch the card and other conditions, and affects the normal operation;

3. For the problem of the use effect of the scraper chain, a brief analysis is made from the existing fatigue limit and the operational basis of the use, and the mechanism of its action seriously affects the basic facility treatment;

4, scraper blade to break situation and cause transport problems may lead to metal fatigue problems, and these problems may directly affect the basic security processing facilities;

5, the chain is too tight, etc. may lead to excessive pressure in the long-term use of the operation, its diameter is the key to affect the intensity.

Treatment measures:

1, the first question to find a manufacturer!

2. The scraper chain needs to be corrected, and the effective adjustment of the connection form is fundamentally completed by adjusting the direction of the scraper of the overall structure;

3. Perform the adjustment before starting the machine and adjust the tightness reasonably;

4, to avoid excessive wear of the link wheel, and for the basic wear and deformation beyond the design requirements, should also meet the basic needs of the facility, improve the operation process, and timely correction of the possible wear and tear;

5. Strict operation process, combined with actual shutdown and start-up actions, reasonable and precise control of the operation process.

Third, the prevention and management of common personal accidents in scraper conveyors

The problem of the specific operation of the staff may cause personal injury. This kind of problem is the root cause of the production safety hazard.

1. During the implementation process, the facility inspection should be satisfied to ensure that the surrounding working environment is comprehensively processed during the operation, and the safety performance of the equipment and equipment is determined. For example, in the control and handling of the winch house, the The control of transportation capacity, through the handling of the transportation failure of the scraper conveyor, guarantees the safety from the system;

2. In the process of performing the test, in order to ensure the safety of personnel, it should be strictly tested according to the application in different situations and environments, and comprehensively processed by different detection mechanisms to achieve safety detection and control of the overall structure. And complete the enhancement of energy loss;

3. For the safety of the fully mechanized mining face in the safe production process, it is necessary to strengthen the regular inspection work and specify the internal use specifications of the power supply application system to complete the comprehensive treatment of the basic requirements of the power supply structure and system. , further completing the effective creation of the overall basic information;

4. Strengthen the handling of security failures, improve specific practical operations, and achieve reasonable control over the effects of basic forms of internal structures;

5. Solve the work start accident that may be caused by the external structure and deal with it in time to ensure work safety.
