What are the benefits of improving the technology of vertical elevator?

Mine hoist is an important equipment in the process of coal mine and non-ferrous metal consumption . Hoist safe, reliable, efficient high-speed operation, directly related to the enterprise's consumption situation and economic benefits . Mine hoisting system has multiple links, complex control, fast running speed, inertia mass, complex operating conditions, frequent changes in working conditions and other characteristics.

Certainly mine hoisting system itself has certain safety maintenance measures, but due to the use of environmental conditions of the site, 10 meters vertical hoist offer, the formation of a variety of mechanical components and electrical components of the functional failure, and man-made errors in limiting the operator and excursion monitoring seminars, so that the existing maintenance can not achieve the desired effect, the progress of the accident system is still unable to eliminate . Turntable type hoist

When the loss of control of the hoist trip, not according to the given speed curve operation, 10 m vertical hoist which is good, the elevator over 1 speed, over-volume accidents, so that the wedge guide, damage to skip, affecting the normal consumption of the mine, and even the formation of serious personnel injuries and deaths, coal consumption to bring about grand economic losses.

Therefore, the study of elevator speed control system is constantly a serious subject of common concern in all walks of life. Electrical control mode in a large level of resolution of the elevator can complete a smooth, safe, reliable braking operation, to prevent serious mechanical wear and tear, to avoid large mechanical impact, reduce the maintenance workload of mechanical parts, to extend the service life of machinery. Continuous vertical hoist

With the automation of the mine hoisting system, the progress of the performance of the hoisting system and the progress of the performance of the hoisting equipment, the electrical transmission method puts forward higher requests. The request of mine hoist electromechanical pneumatic drive system is: good speed performance, high speed accuracy, four-quadrant operation, fast forward and reverse, fast dynamic response.

Detailed measures to deal with the chattering problem in multi-rope friction hoist

(1) adhere to the rope groove diameter of each wire rope is equal, and use a dynamometer, calibration method to determine the balance of the tension of the wire rope.

(2) adhere to the precise 1 accurate drum roundness and the shaft radial correct jump, although the hoist chattering problem from time to time performance, but only need to adhere to the key equipment parts of the normal, can reduce the multi-rope friction type hoist chattering problem, 10 meters of vertical hoist consumer manufacturers, to ensure that the mine's peace of mind, and to improve the safety performance of the equipment.

(3) The introduction of disk brake installation, effectively preventing the problem of low reliability of the traditional brake installation, to ensure the smoothness of the braking speed, thus ensuring the reduction of the chattering problem of the multi-rope friction type hoist, further reducing the possibility of risky accidents. Mine hoist braking installation of good and bad directly affects the multi-rope friction hoist chattering problems, and even related to the entire mine coal mine consumption safety issues, the safety and reliability of the hoist depends largely on the braking installation.

Thus, it is also necessary to develop the bearing shell. Before scraping, it is necessary to measure the clearance of the gear pair in the direction of gear width and tooth top clearance. Then, according to the measured value to determine the parallelism and inclination angle of each axis, as well as whether the center distance can meet the requirements.

The request of scraping 1 knife is that the sign of tooth contact is close to the theoretical trace area. The sign of the nominal contact of the circular gear is the interval from the top of the teeth for the concave teeth of the convex teeth and 0.75mn 0.45mn.The contact marks of the gear pair after shaving should eliminate the phenomenon of tooth angle contact or tooth width bias.

The upper and lower interfaces of the main tile and journal should be evenly spread over the entire width of the bearing shell and the contact angle should be guaranteed in the range of 90-120 degrees, the gap between the journal and the bearing should be adjusted to the range of millimeters, and the side gap should be equal to or greater than half of the gap.
