Abstract
The utility model discloses a mine lifting auxiliary safety system, which comprises a novel speed limitation anti-falling device, a speed limitation brake, a universal BF-series anti-falling device and a buffering carrying tank swing table, wherein the novel speed limitation anti-falling device and the speed limitation brake are arranged on a lifting steel wire rope between a hoisting sheave platform and a two-layer platform and used for braking protection of a lifting container by braking the lifting steel wire rope; and when the lifting container falls at an overspeed, and the rope is not broken, the speed limitation anti-falling device and the speed limitation brake reduce the falling speed of the lifting container by performing speed reduction braking on the lifting steel wire rope, so that the lifting container is carried by the buffering carrying tank swing table securely. The universal BF-series anti-falling device is arranged in the lifting container; when the lifting steel wire rope or a connection device is broken, the universal BF-series anti-falling device enables the falling lifting container to be supported to a braking steel wire rope; and in a catching process, the speed limitation anti-falling device and the speed limitation brake assist in braking.
Description
Technical field
The utility model relates to a kind of mine hoisting supplementary security system, and is particularly a kind of multiple functional, the cooperatively interact mine hoisting supplementary security system of work of inner each safety device.
Background technology
The auxiliary safety device of the mine hoisting system that present mine generally uses is the separate equipment of several covers; And do not constitute one the cover multiple functional mutual coordination safety system; Comprise general-duty BF series falling protector, shaft bottom holder jar cage chair generally speaking, prevented putting device; Existing these safety apparatuss can be braked lifting container by actv. when hoisting cable or connecting device generation fracture; Avoid lifting container to fall, also can be or the shock absorbing power when transferring to the shaft bottom that exceeds the speed limit by a small margin in the lifting container normal speed, make lifting container safety stop jar.And when lifting container because cross lick put, hypervelocity by a relatively large margin takes place in reasons such as lifting winch braking failure, misoperation; Even cross at full speed and put and hoisting cable when constantly restricting; Existing BF series falling protector can not be braked lifting container, and the lifting container of transferring that significantly exceeds the speed limit is easy to make holder jar cage chair with preventing putting failure of apparatus big and heavy stone jar accident to take place.Therefore, be necessary to improve existing safety measure, make mine hoisting system be equipped with the multiple functional supplementary security system of a cover systemization.
Summary of the invention
The technical matters that the utility model will solve is: the safety apparatus function to existing in the existing elevator system is incomplete; Significantly exceed the speed limit or cross at full speed and can't effectively brake lifting container when putting at lifting container; Be easy to generate the problem of big and heavy stone jar accident, provide that a cover function is more complete, safety factor is higher, more systematized mine hoisting supplementary security system.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of mine hoisting supplementary security system; Comprise speed limit falling protector, speed limiting brake, BF series falling protector, Tank support damper cage chair, brake wire, auxiliary snub rope, this auxiliary snub rope vertically is fixed on the speed limit falling protector between sheave wheel platform and the two-layer platform, and speed limiting brake is fixed on the two-layer platform; BF series falling protector is installed in lifting container inside; The Tank support damper cage chair is installed on the wellbore bottom support beam, and hoisting cable from up to down passes speed limit falling protector, speed limiting brake successively, and brake wire vertically passes the wedge box in the BF series falling protector.
According to the described a kind of mine hoisting supplementary security system of this case, the realization of its anti-drop function is to determine with the speed that lifting container is transferred.No matter be that hoisting cable or connecting device generation fracture cause lifting container to fall; Or more significantly hypervelocity takes place in reasons such as lifting container is put because of crossing, lifting winch braking failure, misoperation; When as long as the speed of lifting container exceeds the highest safe operation speed of setting; This safety system will be taked corresponding brake measure; Realization combines to brake wire braking with to the hoisting cable brake snub, and brake snub combines with braking fully, and is more reliably feasible aspect handling failure.With existing anti-fall apparatus in comparison, systematization, automation that it has realized anti-fall equipment, make the safety factor of shaft hoisting improve greatly.
Description of drawings
Fig. 1 is the front view of a kind of mine hoisting supplementary security system of the utility model.
Fig. 2 is the lateral plan of a kind of mine hoisting supplementary security system of the utility model.
The specific embodiment
The utility model is a kind of mine hoisting supplementary security system; Can know referring to Fig. 1 and Fig. 2; This kind mine hoisting supplementary security system comprises speed limit falling protector 1, speed limiting brake 2, BF series falling protector 3, Tank support damper cage chair 4, brake wire 5; Auxiliary snub rope 6, it is characterized in that: this auxiliary snub rope 6 vertically is fixed on speed limit falling protector 1 between sheave wheel platform 7 and the two-layer platform 8, and speed limiting brake 2 is fixed on the two-layer platform 8; BF series falling protector 3 is installed in lifting container 9 inside; Tank support damper cage chair 4 is installed on the wellbore bottom support beam, and hoisting cable from up to down passes speed limit falling protector 1, speed limiting brake 2 successively, and brake wire 5 vertically passes the wedge box in the BF series falling protector 3.
Its principle of work is:
Running velocity when preestablishing lifting container 9 and transferring, when lifting container 9 speed surpass the safe operation speed of setting, the control part branch automatic or manual startup mine hoisting supplementary security system in the elevator system.If hoisting cable or connecting device rupture; Speed limit falling protector 1 takes place to move with speed limiting brake 2 hoisting cable is carried out brake snub in this system; Before lifting container 9 is transferred to shaft bottom contact Tank support damper cage chair 4, lifting container 9 speed are reduced in the safety speed, assurance Tank support damper cage chair 4 can be accepted lifting container 9 safely; When lifting container 9 falls if hoisting cable or connecting device take place to rupture; Speed limit falling protector 1 takes place to move with speed limiting brake 2 hoisting cable is carried out brake snub in this system; 3 pairs of brake wires 5 of BF series falling protector are arrested braking, in this process, and 3 main brake actions of BF series falling protector; Speed limit falling protector 1 plays the auxiliary braking effect with speed limiting brake 2; Through the brake snub of speed limit falling protector 1 and speed limiting brake 2, reduced power required when BF series falling protector 3 is arrested, prolonged effectively simultaneously and arrested the time.When supplementary security system is worked, be wrapped in the impact that the auxiliary snub rope 6 on the speed limit falling protector 1 produces through flexible absorption glancing impact lifting container 9 self inertia, its buffer action in braking procedure under above-mentioned two kinds of situation.
