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, an elevator is made up of car, counterweight, car and the counterweight parts such as guide rail and towing machine separately, as two or multiple elevator parallel connection, often these parts are complete uses, separate, cause productive costs higher like this, and require larger elevator hoistways size.

Summary of the invention

the object of this invention is to provide a kind of lift appliance including two cars, without the need to counterweight system, reduce productive costs, reduce the size of elevator hoistways.

for achieving the above object, the technical solution used in the present invention is: a kind of lift appliance, comprise two cars, support the sedan-chair frame of each described car, the car diversion sheave be arranged on each described sedan-chair frame, towing machine, upwards walk around the traction steel-cable of the traction sheave of described towing machine, the part that this traction steel-cable is positioned at described towing machine both sides respectively under walk around the car diversion sheave of a described car, the both ends after this traction steel-cable walks around the car diversion sheave of described two cars respectively are all arranged in the hoistway of elevator by rope head component.

preferably, be connected with compensated chain or compensate between the bottom of a described car or sedan-chair frame and the bottom of car described in another or sedan-chair frame and restrict.

during concrete enforcement, described two cars are arranged in a described hoistway, and two described hoistways at described two car places are arranged side by side or relative angle arrangement mutually.

during concrete enforcement, the enabling of described two cars is towards being identical or contrary or perpendicular.

during concrete enforcement, the car diversion sheave of corresponding each described car all has two, and the line of centres of two described car diversion sheaves extends along the direction, back and forth or left and right of car, or is obliquely installed relative to the direction, back and forth or left and right of car.

during concrete enforcement, described two cars are arranged in a described hoistway, two described hoistway relative angle arrangements at described two car places, the car diversion sheave of corresponding each described car all has two, two described car diversion sheaves angular direction is intervally arranged along car, the radial surface of each described car diversion sheave, the line of centres angular direction is extended all along car of described two car diversion sheaves, described car to angular direction and described two hoistways arrange corresponding to angular direction, the enabling of described two cars is towards facing vertical setting or back to vertical setting.

during concrete enforcement, described two cars share a set of control system.

during concrete enforcement, described elevator is for having machine room elevator or machine-roomless lift.

due to the utilization of technique scheme, the present invention compared with prior art has following advantages: in this lift appliance, two cars do contrary dipping and heaving by one group of continuous print Steel rope drive, two cars share a towing machine, without the need to using counterweight system, simplify the structure of elevator, greatly reduce the dimensional characteristic of elevator hoistways, cost-saving; And when car load hour (namely seating capacity is few) or two cars all have more passenger, the tension force difference on the steel rope of towing machine both sides is less, and elevator operating ratio traditional elevator is more steady.

Detailed description of the invention

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

shown in Fig. 1-3, one has machine room or elevator without machine room, comprise two cars 2 and 3, support the sedan-chair frame (not shown) of each car, be arranged on the 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 respectively under walk around the car diversion sheave 7 (8) of a car 2 (3), both ends after this traction steel-cable 4 walks around the car diversion sheave 7 and 8 of two cars 2 and 3 respectively are all arranged in the hoistway 6 of elevator by rope head component, such steel rope 4 realizes traction ratio 2:1.Under the driving effect of towing machine 1, steel rope 4 drives two cars 2 and 3 to do contrary dipping and heaving.In this lift appliance, two cars 2 and 3 drive by one group of continuous print steel rope 4 does dipping and heaving, and two cars 2 and 3 share towing machine, an a set of control system, without the need to using counterweight system, simplify the structure of elevator, greatly reduce the dimensional characteristic of elevator hoistways, cost-saving; And when car load hour (namely seating capacity is few) or two cars all have more passenger, the tension force difference on the steel rope of towing machine both sides is less, and elevator operating ratio traditional elevator is more steady.

in FIG, be connected with compensated chain 5 or compensate rope 5 between the bottom of a car 2 or sedan-chair frame and the bottom of another car 3 or sedan-chair frame.This compensated chain or compensation rope, by the weight of balance rope, trailing cable, balance the operation of elevator.

in fig. 1-3, two cars 2 and 3 are arranged in a hoistway 6, and in Fig. 1-2, two cars 2 are arranged side by side mutually with two hoistways 6 at 3 places, and in figure 3, two hoistway 6 relative angle arrangements.In other implementations, the layout of hoistway 6 can adjust according to the requirement of concrete building.The enabling of two cars 2 and 3 is towards being also can carry out adjusting according to the requirement of the layout of hoistway 6 or building, and such as saying, the enabling of two cars 2 and 3 is towards being identical or contrary or perpendicular.By Fig. 2, before in car 2, the position at gate 21 place is defined as, after the position at sedan-chair rear wall 22 place is defined as, the position at sedan-chair sidewall 23,24 place is defined as 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 figure 3, gate 21(31) position also can be arranged on car 2(3) sedan-chair rear wall 22(32), sedan-chair sidewall 23(33), 24(34) position at place.

in fig. 1-3, corresponding each car 2(3) car diversion sheave 7(8) all have two, two car diversion sheave 7(8) and the line of centres extend along the direction, back and forth or left and right of car, as shown in Figure 1-2, or be obliquely installed relative to the direction, back and forth or left and right of car, as shown in Figure 3.

in figure 3, two hoistway 6 relative angle arrangements at two car 2 and 3 places, two car diversion sheave 7(8) along car 2(3) angular direction is intervally arranged, each car diversion sheave 7(8) radial surface, two car diversion sheave 7(8) the line of centres all along car 2(3) angular direction is extended, car 2,3 to angular direction and two hoistways 6 arrange corresponding to angular direction, two cars 2 with 3 enabling towards facing vertical setting, as Fig. 3, or back to vertical setting, can adapt to according to specific requirement.
