Abstract

The utility model discloses a novel traction-type household elevator layout structure. The two ends of a traction rope are fixed, the traction rope bypasses sequentially a movable car pulley, a traction wheel and a movable counterweight pulley, the movable car pulley is fixed on a car, the movable counterweight pulley is fixed on a counterweight, the axial lines of the movable car pulley and the movable counterweight pulley are vertical to the axial line of the traction wheel, and a counterweight guide rail and a car guide rail are arranged on one side face of the car and are arranged in a horizontal plane from inside to outside. The overall structure is compact, the distance between the counterweight and the car is reduced and the occupied space of an elevator shaft way is saved.

Description

A kind of arrangement structure of later-model traction-type home lift

Technical field

The utility model relates to traction class elevator, relates in particular to a kind of arrangement structure of traction-type home lift.

Background technology

At present, the traction home lift is general to adopt asynchronous towing machine to drive, employing be 1: 1 wiring ratio because there is reductor to exist, the corresponding oil pollution that exists, noise is big, the shortcoming that energy efficiency is low; And by " home lift manufacturing and installation specification " (GB/T21739-2008) requirement must join wire holder or counterweight safety, influence the complete machine compact in design, cause and the used elevator hoistways of elevator is installed is taken up room relatively large.

The utility model content

The purpose of this utility model provides a kind of arrangement structure of later-model traction-type home lift, can make elevator hoistways corresponding the reducing that take up room.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of arrangement structure of later-model traction-type home lift, the hoist ropes two ends are fixed, and walk around the cab movable pulley successively, traction sheave, the counterweight movable pulley, described cab movable pulley is fixed on the car, described counterweight movable pulley is fixed on the counterweight, described cab movable pulley, counterweight movable pulley axis and traction sheave axis normal, counterweight guide rail and car guide rail are positioned at the same side of car, are in one outside one at horizontal surface and arrange.

The beneficial effects of the utility model: by the cab movable pulley being fixed on a car side of close counterweight, the counterweight movable pulley is fixed on the counterweight upper surface, the pivot center of cab movable pulley is parallel with the pivot center of counterweight movable pulley, the pivot center of cab movable pulley is vertical with the pivot center of traction sheave, the layout that the pivot center of counterweight movable pulley is vertical with the pivot center of traction sheave, compare with traditional elevator drag device, the counterweight movable pulley, horizontal throw between cab movable pulley and the traction sheave is shortened as far as possible, reduce the distance between counterweight and the car, thereby realized saving the purpose that elevator hoistways takes up room.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the arrangement principle schematic of traction-type home lift described in the utility model;

Fig. 2 is the hoistway planar view that the arrangement of traction-type home lift described in the utility model adopts;

Among the figure:

1, traction sheave; 2, cab movable pulley; 3, counterweight movable pulley; 4, car; 5, counterweight; 6, hoist ropes; 7, car guide rail; 8, counterweight guide rail.

The specific embodiment

As shown in Figure 1, provided the theory structure scheme drawing of the arrangement of a kind of traction-type home lift of the present utility model.Hoist ropes 6 two ends are fixed, and are fixed on the top of elevator hoistways, and walk around cab movable pulley 2 successively, traction sheave 1, and counterweight movable pulley 3, traction sheave 1 is a fixed pulley, is fixed in the top of elevator hoistways.Its hoistway floor plan as shown in Figure 2, cab movable pulley 2 is fixed on the load larrying member of car 4 the most close counterweight 5 one sides, counterweight movable pulley 3 is fixed on the load larrying member of upper surface of counterweight 5, counterweight guide rail 8 and car guide rail 7 are positioned at the same side of car, are one in layout outside at horizontal surface.

When elevator rose, towing machine drove traction sheave 1 and rotates counterclockwise, and counterweight 5 descends, and counterweight movable pulley 3 moves downward, and hoist ropes 6 drives cab movable pulley 2 upward movements simultaneously, and car 4 rises, and realized that elevator rises.

When elevator descended, towing machine drove traction sheave 1 and clockwise rotates, and counterweight 5 rises, counterweight movable pulley 3 upward movements, and hoist ropes 6 drives cab movable pulley 2 and moves downward, and car 4 descends, and realizes that elevator descends.

The pivot center of cab movable pulley 2 is parallel with the pivot center of counterweight movable pulley 3, and the pivot center with traction sheave 1 is vertical respectively, that is to say, cab movable pulley 2 and counterweight movable pulley 3 horizontal throw only be equivalent to the diameter of traction sheave 1; Counterweight guide rail 8 and car guide rail 7 are positioned at the same side of car, are in one outside one at horizontal surface and arrange that this kind arrangement reduces the elevator hoistways occupation space to a great extent.

Claims

1. the arrangement structure of a later-model traction-type home lift, the hoist ropes two ends are fixed, and walk around the cab movable pulley successively, traction sheave, the counterweight movable pulley, described cab movable pulley is fixed on the car, described counterweight movable pulley is fixed on the counterweight, it is characterized in that: described cab movable pulley, counterweight movable pulley axis and traction sheave axis normal, counterweight guide rail and car guide rail are positioned at the same side of car, are in one outside one at horizontal surface and arrange.
