Description
Technical field
The utility model relates to the energy disperser in a kind of mine usefulness anti-drop system, especially a kind of roll friction formula energy disperser.
Background technology
The appreciiable mine of China adopts vertical list rope cage (skip bucket) as lifting container at present.According to country's " safety regulations in coal mine " the 383rd: single rope cage of lifting personnel or lifting personnel and lifting material, carry the skip bucket in the human world, must stipulate by installing failure-free falling protector, when using single rope cage or single rope to carry the coal skip bucket as lifting container, all installed the falling protector of lifting container.
The tradition anti-drop system generally is comprised of following part:
A) be installed in the steel rope energy disperser on derrick top;
B) buffer rope and brake wire and adaptor union thereof;
C) be installed in anti-fall (arresting) device on the cage (skip bucket);
D) be installed in the brake wire take-up device etc. in shaft bottom.
Wherein conventional buffer structure and principle of work: be to rely on buffering wheel and pressure adjusting roller that buffer rope is pressed into bending, the friction in the middle of buffering wheel and pressure adjusting roller realizes buffer-braking power by buffer rope.Its shortcoming is: 1. energy disperser belongs to the safety protection facility of elevator system, and effect is " preparing for the worst ", and because of on the shelf for a long time, the long-term pressurized of buffer rope in the energy disperser easily becomes " permanent deformation " and lost efficacy.2. work as lifting container and drop for some reason, the buffer rope of pressurized weares and teares (being pressed into the fitfull ellipse) because of violent friction force in the energy disperser, thereby after each action, needs to change the buffer rope that lost efficacy because of deformation in compression.3. should do once the requirement of disconnected rope tenesmus test " safety regulations in coal mine " every year according to country, whenever doing once must the exchange buffering steel rope.Because the buffer rope other end is integrated with Babbitt matal and adaptor union filling, buffer rope and adaptor union need to change synchronously, operate very loaded down with trivial details, Babbitt matal is expensive, cost is higher, and to change production time longer at every turn, has a strong impact on the normal production of ore deposit side, even have the part mine to be reluctant to change adaptor union, cause a hidden trouble to safety in production.
In order to address this problem, people have carried out a large amount of research.A kind of friction roll cartridge type buffer that has been 94242152.3 patent disclosure such as the patent No., it is to be fixed with jam nut at the two ends of axle, left end is equipped with spring and platen, the centre is equipped with the static friction sheet, the two ends of axle is fixed on the axle bed motionless, drum inner surface is equipped with movable friction plate, and dynamic and static friction lining is alternately installed.Twine and fix under the pulling of steel rope of an end at outer surface of cylinder, drive the rotation of cylinder and movable friction plate, make and produce the buffering friction force between dynamic and static friction lining.This device has certain preceence, but it is the constant force buffering, and effect is bad during braking, and spring device is arranged on the outside, drenches with rain easily, has affected its service life.
