The specific embodiment
Referring to illustrated in figures 1 and 2, said lift appliance comprises that hoist trunk 19, car 3, counterweight 4, cage side return the actuating device 1 that rope sheave 11, counterweight side return rope sheave 10, have drive pulley 2 and car 3 is gone up and down; Car 3 goes up and down to move along two car guide rails in the hoist trunk 19 12, and counterweight 4 is along the 13 up-down operations of two weight guides in the hoist trunk 19, and wherein the both sides of car 3 respectively are provided with a pair of car wheel 7, and the top of counterweight 4 is provided with two weighting distribution wheels 9; Said drive pulley 2, car wheel 7, weighting distribution wheel 9, cage side are returned rope sheave 11 and counterweight side and are returned and be wound with the rope 8 that carries car 3 and counterweight 4 between the rope sheave 10; Car 3 has gate 5, and lift appliance has layer door 6 simultaneously.
Said actuating device 1 adopts the strip shape structure, and promptly the axial dimension of actuating device 1 is greater than the diameter of drive pulley 2, and drive pulley 2 is approaching vertical with adjacent car 3 edges.Actuating device 1 and drive pulley 2 are arranged on the top layer upper space of hoist trunk 19.
Two cars of car 3 homonymies are taken turns 7 adjacent settings, are positioned at the below of actuating device 1 near two cars wheel 7 of actuating device 1 one sides, and cage side is returned rope sheave 11 and is positioned at the top away from two cars wheels 7 of actuating device 1 one sides.Counterweight return rope sheave 10 in the projection on the up-down vertical direction between two weighting distribution wheels 9.
Above hoist trunk 19, be provided with respectively and return rope sheave support beam 15 and bearing beam 14; Cage side is returned rope sheave 11 and is located at and returns on the rope sheave support beam 15; Actuating device 1 is located on the bearing beam 14, can reduce the intensity of car guide rail 12 like this, thereby can reduce the cost of car guide rail 12.For the force request that reduces bearing beam 14, the design of simplifying bearing beam 14; The top of weight guide 13 is provided with a support platform 16; Said counterweight side is returned rope sheave 10 and is supported on the said support platform 16, and half is supported on two weight guides 13 at least in the load of counterweight side like this.In order to increase the intensity of support platform 16, support platform 16 can be supported by two weight guides 13 and a car guide rail 12, and can utilize the intensity of a part of car guide rail 12 this moment, makes support platform 16 reliable more and firm.
As shown in Figure 1; Cage side cable end 17 is supported on the bearing beam 14 with counterweight side cable end 18; Certainly under the situation that weight guide 13 intensity allow, also can counterweight side cable end 18 be supported on the support platform 16,14 of bearing beams bear about 1/4 of counterweight side heavy burden; The requirement of strength of bearing beam 14 further reduces like this, helps the simplified design of bearing beam 14.
Actuating device 1 is between cage side cable end 17 and counterweight side cable end 18, and cage side cable end 17 can not influence the height and position of actuating device 1 with counterweight side cable end 18 like this, thereby can not influence the headroom height of lift appliance.
As shown in Figure 2; Respectively there are two car wheels 7 both sides of car 3; Two cars of homonymy are taken turns 7 arranged adjacent, are positioned at a side of car guide rail 12, and the car wheel 7 of car 3 both sides lays respectively at the not homonymy of car guide rail 12; The layout of car wheel 7 can not influence the layout of velocity limiter like this, and this moment, velocity limiter can be arranged on the opposite side of taking turns 7 relative car guide rails 12 with car.In addition because two car 7 arranged adjacent of homonymy; Cage side is returned the top that rope sheave 11 is arranged in two car wheels 7; Rope 8 reverses not severe when 7 suspensions of car wheel like this; The noise that car wheel 7 produces is little, and the gap between the rope 8 guarantees easily, more difficult generation rope clash when elevator moves.
More than through embodiment the utility model has been carried out detailed explanation, but these are not the restriction of formation to the utility model.Under the situation that does not break away from the utility model principle, those skilled in the art also can make many distortion and improvement to the position of elevator components, and these also should be regarded as the protection domain of the utility model.
