Description
Technical field
It the utility model is related to mine hoist brake control art, and in particular to a kind of mine hoist constant deceleration brake
System.
Background technology
Mine hoist is the throat equipment of mining, carries mineral, equipment, material and personnel between underground
The vital task of conveying, its performance quality are particularly significant for Mine Safety in Production.And mine hoisting brake system is relation
To the critical component of mine hoist safety performance.
Sure brake system uses constant moment of force brakes mostly in present coal production, but constant moment of force mode of braking has
2 deficiencies：First, for cylindrical drum hoist, pit shaft is deeper, and steel wire rope is longer, therefore in the outlet of mine and mine
During bottom, influenceed by steel wire own wt, steel wire rope tension change is bigger, cause the amplitude of elevator acceleration change compared with
Greatly, larger impact can be produced to lifting system；Second, for friction type winder, when the imbalance in lifting system is born
When carrying excessive, steel wire rope can be easily caused the phenomenon skidded occur in brake hard.Therefore, if can a energy root of successful design
Implement the permanent deceleration system of regulating brake force square according to actual condition, elevator is kept deceleration constantly in braking procedure
It is worth invariable, avoids two problems of constant moment of force system, it will highly significant.
The content of the invention
The purpose of this utility model is to provide a kind of mine-hoist constant deceleration system.
The technical solution of the utility model is：A kind of mine-hoist constant deceleration system, its composition include：Two four

Cross fluid pressure line to be connected with filter, described filter is connected with two-bit triplet magnetic valve, reversal valve respectively by fluid pressure line
Connect, described two-bit triplet magnetic valve is connected by fluid pressure line with accumulator, and described two-bit triplet magnetic valve passes through hydraulic pressure
Pipeline is connected with voltmeter, and described reversal valve is connected with electro-hydraulic proportional valve one, electro-hydraulic proportional valve two.
A kind of described mine-hoist constant deceleration system, described accumulator are provided with fluid pressure line junction
Choke valve, described voltmeter are provided with choke valve with hydraulic pipeline junction.
A kind of described mine-hoist constant deceleration system, the hydraulic pipeline between described filter and reversal valve
On sensor is installed.
Beneficial to synergy
A kind of mine-hoist constant deceleration system of the utility model design, can fully overcome constant moment of force braking side
Two deficiencies of formula, it can realize and be slowed down according to the perseverance of the real-time regulating brake force square of actual condition, so that elevator is being braked
During can keep deceleration value invariable constantly.
