Abstract
The utility model discloses an elevator without a machine room at a rope winding ratio of 4:1. The elevator comprises a well, a dragging machine and a speed limiter, wherein a pulley D is arranged at the top of the well; a pulley C1, a pulley C2 and a tensioning device are arranged at the bottom of the well; a control cabinet, a cage and a steel wire rope are arranged on the well; a pulley A1 and a pulley A2 are arranged at the top of the cage; a pulley B1 and a pulley B2 are arranged at the bottom of the cage; one end of the steel wire rope is fixed at the top of the well and passes by the pulley A1, the pulley D, the pulley A2, a dragging wheel on the dragging machine, the pulley C1, the pulley B1, the pulley C2 and the pulley B2 in turn; and the other end of the steel wire is connected with the tensioning device. A novel dragging system at the rope winding ratio of 4:1 is adopted by the elevator provided by the utility model; a wrapping angle of the dragging wheel is at 180 degrees; the dragging capacity of the whole machine is higher; the steel wire is difficult to deflect; the service life of the steel wire and guide shoes is prolonged; and besides, the elevator is free from counterweight, is simply mounted and positioned and is higher in use ratio of well space.
Description
Technical field
The utility model relates to a kind of machine-roomless lift, particularly a kind of machine-roomless lift of 4 to 1 wirings ratio.
Background technology
Elevator is a kind of vertical conveyor take electrical motor as power, and case shape gondola is housed, and is used for tier building and takes advantage of people or carrying goods.Elevator is as the transport facility of vertical direction, become important Architectural Equipment in skyscraper and public place and indispensable.Along with the development of computer technology, automatic technology and Power Electronic Technique, modem elevator has become typical electromechanical integrated product.Raising along with whole national economy strength, the people's personal consumption level rises appreciably, the real estate developer releases medium-to-high grade little high level and high-rise residential building one after another energetically, has driven increasing rapidly of residential lift, becomes the main growth point in whole elevator market.
Existing machine-roomless lift, it is provided with the side track adjusting wheel to heavy side or cage side, makes the cornerite of its traction sheave less than 180 degree, the pulling ability of whole ladder is lower, the easy sideslip of steel rope causes the monolateral boots heel and toe wear of leading, and has reduced steel rope and the service life of leading boots; In addition, the layout of existing machine-roomless lift traction system also exists structure design and hoistway utilization reasonable not, and the shortcoming of location difficulty is installed.
The utility model content
The purpose of this utility model is, a kind of machine-roomless lift of 4 to 1 wirings ratio is provided.The utlity model has pulling ability higher, the advantage that component life is longer; And traction system structure compactness reasonable in design, the hoistway utilization is reasonable, and the location simple and fast is installed.
The technical solution of the utility model: a kind of machine-roomless lift of 4 to 1 wirings ratio, comprise hoistway, towing machine and velocity limiter, well headroom is provided with the D pulley, and the hoistway bottom is provided with C1 pulley, C2 pulley and swelling device; Also be provided with control housing, car and steel rope on the hoistway, car top is provided with A1 pulley and A2 pulley, the car bottom is provided with B1 pulley and B2 pulley, steel rope one end is fixed on well headroom, walk around successively traction sheave, C1 pulley, B1 pulley, C2 pulley and B2 pulley on A1 pulley, D pulley, A2 pulley, the towing machine, the steel rope other end is connected with swelling device.
In the machine-roomless lift of aforesaid 4 to 1 wirings ratio, it is characterized in that: described well headroom is provided with bearing beam, and D pulley, towing machine and velocity limiter are arranged on the bearing beam.
Compared with prior art, the utility model adopts a kind of novel wiring than the traction system that is 4 to 1, and the cornerite of traction sheave is 180 degree, and the complete machine pulling ability is higher, and steel rope is difficult for sideslip, has improved steel rope and the service life of leading boots; In addition, the utility model need not counterweight, the location is installed simply, and the hoistway space degree of utilization is higher.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-hoistway, 2-D pulley, 3-towing machine, 4-velocity limiter, 5-C1 pulley, 6-C2 pulley, the 7-swelling device, 8-control housing, 9-car, 10-steel rope, 11-A1 pulley, the 12-A2 pulley, 13-B1 pulley, 14-B2 pulley, 15-bearing beam, 16-traction sheave.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of machine-roomless lift of 4 to 1 wirings ratio consists of as shown in Figure 1, comprises hoistway 1, and hoistway 1 top is provided with D pulley 2, towing machine 3 and velocity limiter 4, and hoistway 1 bottom is provided with C1 pulley 5, C2 pulley 6 and swelling device 7; Also be provided with control housing 8, car 9 and steel rope 10 on the hoistway 1, car 9 tops are provided with A1 pulley 11 and A2 pulley 12, car 9 bottoms are provided with B1 pulley 13 and B2 pulley 14, steel rope 10 1 ends are fixed on hoistway 1 top, walk around successively traction sheave 16, C1 pulley 5, B1 pulley 13, C2 pulley 6 and B2 pulley 14 on A1 pulley 11, D pulley 2, A2 pulley 12, the towing machine 3, steel rope 10 other ends are connected with swelling device 7.
Described hoistway 1 top is provided with bearing beam 15, and D pulley 2, towing machine 3 and velocity limiter 4 are arranged on the bearing beam 15.
The utility model utilizes assembly pulley labour-saving principle of work, and need not counterweight, and the cornerite of traction sheave 16 is 180 degree, so that towing machine 3 can draw with less tractive force the car 9 of same load carrying ability.
