What are the benefits of improved vertical hoist technology?
Mine hoist is an important equipment in coal mine and nonferrous metal consumption The safe, reliable and efficient high speed operation of the hoist is directly related to the consumption and economic benefits of the enterprise Mine hoisting system has the characteristics of multi links, complex control, fast operation speed, large inertia mass, complex operation conditions and frequent changes of working conditions
Although the mine hoisting system itself has certain safety maintenance measures, due to the use of the website of environmental conditions, the quotation of 10m vertical hoist, the functional failure of various mechanical and electrical components, and the limitation of human errors, the monitoring and discussion of operators and tours, the existing maintenance can not achieve the expected effect, and the accident system has not been eliminated Rotary elevator
When the elevator stroke is out of control and does not operate according to the given speed curve, which is better for the 10m vertical elevator? The occurrence of elevator overspeed and overwinding accidents will lead to wedge guide, damage and skip, affect the normal consumption of the mine, and even cause serious personal injury and death, and coal consumption will bring great economic losses
Therefore, the research on elevator speed control system is a serious topic of common concern The electrical control mode determines to a great extent that the hoist can complete stable, safe and reliable braking operation, prevent serious mechanical wear, avoid large mechanical impact, reduce the maintenance workload of mechanical parts and prolong the service life of the machinery Continuous vertical hoist
With the automation of mine hoisting system, the progress of hoisting system performance and the progress of hoisting equipment performance, higher requirements are put forward for electric drive mode The requirements of electromechanical pneumatic drive system of mine hoist are: good speed regulation performance, high speed regulation accuracy, four quadrant operation, fast forward and reverse, fast dynamic response
Detailed treatment measures for vibration problem in multi rope friction hoist
1) The rope groove diameter of each steel wire rope shall be equal, and the tension balance of the steel wire rope shall be measured by dynamometer, calibration method, etc.
2) Adhere to the accurate roundness of the drum and the correct radial runout of the shaft. Although the vibration problem of the hoist occurs from time to time, the vibration problem of the multi rope friction hoist can be reduced only by adhering to the normal of the key equipment parts. The consumer manufacturer of the 10m vertical hoist can ensure the safety of the mine and improve the safety performance of the equipment.
3) The introduction of disc brake installation effectively prevents the problem of low reliability of traditional brake installation, ensures the stability of braking speed, so as to reduce the vibration problem of multi rope friction hoist and further reduce the possibility of risk accidents. The quality of braking installation of mine hoist directly affects the vibration problem of multi rope friction hoist, and even related to the safety of coal consumption in the whole mine. The safety and reliability of hoist largely depends on braking installation.
Therefore, it is also necessary to develop bearing shells. Before scraping, the clearance of the gear pair in the gear width direction and the tooth top clearance must be measured. Then, according to the measured value, confirm whether the parallelism and inclination angle of each axis and the center distance can meet the requirements.
The request of scraper 1 is that the tooth surface contact mark is close to the theoretical trace area. The nominal contact marks of circular arc gears are convex teeth with concave teeth and 0.75mn and 0.45mn The contact trace of gear pair after shaving shall eliminate the phenomenon of tooth angle contact or tooth width deviation.
The main pads and journals at the upper and lower interfaces shall be evenly distributed over the whole width and contact angle of the bearing shell, and the clearance between journals and bearings shall be adjusted to within mm, and the side clearance shall be equal to or greater than half of the clearance.
