Abstract

The invention discloses a lift device, wherein two lift cars are driven continuously by a group of steel ropes to move up and down oppositely and share the common traction machine without utilizing a counter-weight system, so that a lift structure is simplified, size requirement to a lift well is greatly lowered, cost is saved. Furthermore, when the load of the lift cars is light (namely, few passengers) or two lift cars carry more passengers, tension difference between two steel ropes of the traction machine is quite small, and operation of the lift device is more stable than that of a traditional lift.

Description

A kind of lift appliance

Technical field

the present invention relates to a kind of lift appliance.

?

Background technology

generally speaking; Elevator is made up of parts such as car, counterweight, car and counterweight guide rail and towing machines separately; When two or the parallel connection of many elevators, often these parts are complete use, and are separate; Cause productive costs higher like this, and require bigger elevator hoistways size.

?

Summary of the invention

the purpose of this invention is to provide a kind of lift appliance that includes two cars, need not counterweight system, reduce production costs, and reduce the size of elevator hoistways.

are for achieving the above object; The technical scheme that the present invention adopts is: a kind of lift appliance; Comprise two cars, support each said car the sedan-chair frame, be arranged on car diversion sheave on each said sedan-chair frame, towing machine, upwards walk around the traction steel-cable of the traction sheave of said towing machine; The part that this traction steel-cable is positioned at said towing machine both sides is walked around the car diversion sheave of a said car respectively downwards, and the both ends that this traction steel-cable is walked around respectively behind the car diversion sheave of said two cars all are arranged in the hoistway of elevator through the fag end assembly.

preferably are connected with compensated chain or compensation rope between the bottom of said car or sedan-chair frame and the bottom of another said car or sedan-chair frame.

During practical implementation, said two cars are arranged in the said hoistway, and two said hoistways at said two cars place are arranged side by side mutually or relative angle is arranged.

During practical implementation, the opening the door towards being identical or opposite or perpendicular of said two cars.

During practical implementation; The car diversion sheave of corresponding each said car all has two; The line of centres of two said car diversion sheaves extends along the front and back or the left and right directions of car, and perhaps front and back or the left and right directions with respect to car is obliquely installed.

During practical implementation; Said two cars are arranged in the said hoistway; Two said hoistway relative angles at said two cars place are arranged; The car diversion sheave of corresponding each said car all has two, and two said car diversion sheaves are intervally arranged along the diagonal of car, and the line of centres of the radial surface of each said car diversion sheave, said two car diversion sheaves all extends along the diagonal of car; The diagonal of said car is corresponding with the diagonal that said two hoistways are arranged, and opening the door of said two cars is provided with perhaps back to vertical setting towards facing vertically mutually.

During practical implementation, the shared cover control system of said two cars.

During practical implementation, said elevator is organic machine room-free elevator or machine-roomless lift.

are because the utilization of technique scheme; The present invention compared with prior art has advantage: in this lift appliance, two cars are driven by one group of continuous steel rope and do opposite dipping and heaving, two shared towing machines of car; Need not to use counterweight system; Simplify the structure of elevator, dwindled the dimensional characteristic of elevator hoistways greatly, practiced thrift cost; And when car load hour (being that seating capacity is few) or two cars all had more passenger, the tension force difference on the steel rope of towing machine both sides was less, and elevator operating ratio traditional elevator is more steady.

The specific embodiment

Structure of the present invention is further set forth below in conjunction with accompanying drawing in .

are referring to shown in Fig. 1-3; A kind of have machine room or an elevator without machine room; Comprise two cars 2 and 3, support each car sedan-chair frame (not shown), be arranged on car diversion sheave 7 (8) on each sedan-chair frame, towing machine 1, upwards walk around the traction steel-cable 4 of the traction sheave 11 of towing machine 1; The part that this traction steel-cable 4 is positioned at towing machine 1 both sides is walked around the car diversion sheave 7 (8) of a car 2 (3) respectively downwards; The both ends that this traction steel-cable 4 is walked around respectively behind the car diversion sheave 7 and 8 of two cars 2 and 3 all are arranged in the hoistway 6 of elevator through the fag end assembly, and steel rope 4 is realized traction ratio 2:1 like this.Under the driving action of towing machine 1, steel rope 4 drives two cars 2 and 3 and does opposite dipping and heaving.In this lift appliance, two cars 2 and 3 are driven by one group of continuous steel rope 4 and do dipping and heaving, and two cars 2 overlap control system with 3 shared towing machines; Need not to use counterweight system; Simplify the structure of elevator, dwindled the dimensional characteristic of elevator hoistways greatly, practiced thrift cost; And when car load hour (being that seating capacity is few) or two cars all had more passenger, the tension force difference on the steel rope of towing machine both sides was less, and elevator operating ratio traditional elevator is more steady.

are connected with compensated chain 5 or compensation rope 5 between the bottom of car 2 or sedan-chair frame and the bottom of another car 3 or sedan-chair frame in Fig. 1.This compensated chain or compensation rope are through the weight of balance rope, trailing cable, the operation that comes the balance elevator.

In Fig. 1-3, two

cars

2 and 3 are arranged in the hoistway 6 , and in Fig. 1-2, two hoistways 6 at two cars 2 and 3 places are arranged side by side mutually, and in Fig. 3, two hoistway 6 relative angles are arranged.In other embodiment, the layout of hoistway 6 can be adjusted according to the requirement of concrete building.Two cars 2 and 3 open the door towards also being to adjust according to the layout of hoistway 6 or the requirement of building, such as saying, two cars 2 and 3 open the door towards being identical or opposite or perpendicular.By Fig. 2, with the location definition at gate in the car 2 21 place be before, after the location definition at sedan-chair rear wall 22 places is; The location definition at sedan- chair sidewall 23,24 places is left and right; Then in other embodiment, the position of gate 21 also can be arranged on rear portion, the left part of car, in like manner; In the car 3 of Fig. 2, the position of gate 31 also can be arranged on rear portion, the right part of car.Equally, in Fig. 3, the position of gate 21 (31) also can be arranged on the sedan-chair rear wall 22 (32) of car 2 (3), the position at sedan-chair sidewall 23 (33), 24 (34) places.

are in Fig. 1-3; The car diversion sheave 7 (8) of corresponding each car 2 (3) all has two; The line of centres of two car diversion sheaves 7 (8) extends along the front and back or the left and right directions of car; Shown in Fig. 1-2, perhaps front and back or the left and right directions with respect to car is obliquely installed, and be as shown in Figure 3.

are in Fig. 3; Two hoistway 6 relative angles at two cars 2 and 3 places are arranged; Two car diversion sheaves 7 (8) are intervally arranged along the diagonal of car 2 (3), and the line of centres of the radial surface of each car diversion sheave 7 (8), two car diversion sheaves 7 (8) all extends along the diagonal of car 2 (3), and the diagonal of car 2,3 is corresponding with the diagonal that two hoistways 6 are arranged; Two cars 2 and 3 open the door towards mutually in the face of vertical setting; Like Fig. 3,, can adapt to according to specific requirement perhaps back to vertical setting.
