Embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.

As shown in Figure 1, 2, a kind of fall arrest mining elevator, including hoisting gear 1, head sheave 4 and hopper 6, its feature exist In：Fall arrest light-emitting window 2, fall arrest light-emitting window hydraulic motor 3 and fall arrest well 7 are further included,

Fall arrest light-emitting window 2 includes winch runner 21, hopper runner 22, clump weight runner 23, clutch 24, infrared probe 25 and infrared external reflection block 26, winch runner 21 and hopper runner 22 linked together by connecting shaft, clutch 24 is arranged on material Struggle against between runner 22 and clump weight runner 23, hopper runner 22 and clump weight runner 23 are connected by connecting shaft and clutch 24 Connecing, infrared probe 25 is arranged on 24 shell of clutch, and infrared external reflection block 26 is arranged on hopper runner 22,

Storage battery and PLC controller, clutch 24 and fall arrest light-emitting window are provided with fall arrest light-emitting window hydraulic motor 3 Hydraulic motor 3 connects, and infrared probe 25 is connected by data cable with PLC controller,

Guide rail 71 and clump weight 72 are provided with 7 inner wall of fall arrest well, clump weight 72 is installed on guide rail 71,

Steel wire rope I 51 is wound with hoisting gear 1, I 51 other end of steel wire rope is wound on winch runner 21,6 top of hopper It is connected with II 52 one end of steel wire rope, steel wire rope II 52 is wrapped in head sheave 4, and the other end is wrapped on hopper runner 22, counterweight 72 top of block is connected with III 53 one end of steel wire rope, and III 53 other end of steel wire rope is wrapped on clump weight runner 23.

Further, the ratio between head sheave 4 and 22 wheel footpath of hopper runner are 5:1.

Further, infrared probe 25 and 26 central point of infrared external reflection block are to the company between hopper runner 22 and clutch 24 The distance of spindle axial line is equal.

Further, 72 weight of clump weight is the design of hopper 6 dress weight and the sum of 6 weight of hopper twice.

This elevator can prevent from running out of steam when emergency situations because there is unexpected power-off or hoisting gear 1, the pendant of hopper 6 Fall, reduce the security risk of mining.In normal use, clutch 24 disconnects elevator, and hoisting gear 1 can only drive winch to turn Wheel 21 and hopper runner 22 rotate, so as to fulfill the lifting of hopper 6.When there is emergency case and to cause hopper 6 to lose lifting dynamic During power, hopper 6 will quickly fall, and quick fall of hopper 6 will cause hopper runner 22 and 21 rotating speed of winch runner to be accelerated suddenly, Infrared probe 25 will monitor that the unexpected of this 22 this rotating speed of hopper runner is accelerated, and this information is fed back to and is attached thereto PLC controller in, PLC controller by control fall arrest light-emitting window hydraulic motor 3 promote clutch 24 to combine, winch runner 21 It will be connected with clump weight runner 23, and pull clump weight 72 to rise, since 72 weight of clump weight is more than hopper 6 and its ore deposit loaded The gross weight of thing, so that hopper 6 slows down and is finally stopped whereabouts.

Storage battery is provided with fall arrest light-emitting window hydraulic motor 3, even if occurring under powering-off state, storage battery can also be Infrared probe 25 and PLC controller provide the electric energy needed for work, and therefore, the anti-falling function of this elevator can with very high By property.

As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not To limit the utility model, any modification for being made where within the spirit and principles of the present invention, equivalent substitution and change Into etc., it should be included within the scope of protection of this utility model.
