Abstract
The utility model discloses a lift without a machine room. The lift comprises a lift car (1), a traction machine (2) and a control system (3), and is characterized in that the control system (3) is arranged in the lift car (1); the traction machine (2) is arranged on the top of the lift car; the traction ratio of a traction system is 4:1. The control system is arranged in the lift car and the traction machine is arranged on the top of the lift car, so occupied space is small; the novel traction system with the traction ratio being 4:1 is adopted and the wrap angle of a traction wheel is 180 degrees, so the whole machine has high traction capability, a traction rope is unlikely to deviate, and the service life of the traction rope and the service life of a guide shoe are prolonged.
Description
Technical field
The utility model relates to a kind of machine-roomless lift, belongs to the elevator technology field.
Background technology
Elevator is a kind ofly to take electrical motor and be the vertical conveyor of power, and case shape gondola is housed, and takes advantage of people or carrying goods for tier building.Elevator is as the transport facility of vertical direction, in skyscraper and public place, become important Architectural Equipment 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.
Traditional elevator need arrange machine room above hoistway, control system, towing machine etc. is arranged in machine room, takies larger space.In addition, existing elevator, it is provided with the side track adjusting wheel to heavy side or cage side, makes the cornerite of its traction sheave be less than 180 degree, and the pulling ability of whole ladder is lower, and the easy sideslip of hoist ropes causes the monolateral boots heel and toe wear of leading, and affects hoist ropes and the service life of leading boots.
The utility model content
The purpose of this utility model is, a kind of machine-roomless lift is provided.The utility model not only has advantages of and takes up room littlely, and compares existing elevator, has a pulling ability higher, the advantage that component life is longer.
The technical solution of the utility model: a kind of machine-roomless lift comprises car, towing machine and control system; Described set-up of control system is in the inside of car; Described towing machine is arranged on car top, and the traction ratio of traction system is 4:1.
In aforesaid machine-roomless lift, on described towing machine, be wound with hoist ropes, hoist ropes walks around the A pulley that is arranged on well headroom, the B pulley that is arranged on car top, the C pulley that is arranged on car top successively after from towing machine, drawing, be arranged on the D pulley of hoistway bottom, the E pulley that is arranged on the car bottom, the F pulley that is arranged on the hoistway bottom are connected with the swelling device of the G pulley that is arranged on the car bottom bottom being arranged on hoistway.
Compared with prior art, the utility model passes through set-up of control system at cab interior, towing machine is arranged on to car top, make take up room little, and to adopt a kind of novel traction ratio be the traction system of 4:1, the cornerite of traction sheave is 180 degree, and the complete machine pulling ability is higher, hoist ropes is difficult for sideslip, has improved hoist ropes and the service life of leading boots.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-car, 2-towing machine, 3-control system, 4-A pulley, 5-B pulley, 6-C pulley, 7-D pulley, 8-E pulley, 9-F pulley, 10-G pulley, 11-swelling device, 12-hoist ropes.
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, form as shown in Figure 1, comprises the elevator configuration such as car 1, towing machine 2 and control system 3; Be characterized in: described control system 3 is arranged on the inside of car 1; Described towing machine 2 is arranged on car top, and the traction ratio of traction system is 4:1.
On described towing machine 2, be wound with hoist ropes 12, hoist ropes 12 is connected from walking around successively A pulley 4, the B pulley 5 that is arranged on car 1 top, the C pulley 6 that is arranged on car 1 top, the D pulley 7 that is arranged on the hoistway bottom that is arranged on well headroom, the E pulley 8 that is arranged on car 1 bottom, the F pulley 9 that is arranged on the hoistway bottom and the swelling device 11 of the G pulley 10 that is arranged on car 1 bottom bottom being arranged on hoistway after towing machine 2 is drawn.
The utility model, by control system 3 being arranged on to car 1 inside, is arranged on car 1 top by towing machine 2, make take up room little; The utility model utilizes assembly pulley labour-saving principle of work, and without counterweight, the cornerite of traction sheave is 180 degree, makes towing machine 2 can draw with less tractive force the car 1 of same load carrying ability.
Claims (2)
1. a machine-roomless lift, comprise car (1), towing machine (2) and control system (3); It is characterized in that: described control system (3) is arranged on the inside of car (1); Described towing machine (2) is arranged on car top, and the traction ratio of traction system is 4:1.
2. machine-roomless lift according to claim 1, it is characterized in that: on described towing machine (2), be wound with hoist ropes (12), hoist ropes (12) is walked around the A pulley (4) that is arranged on well headroom successively after towing machine (2) is drawn, be arranged on the B pulley (5) at car (1) top, be arranged on the C pulley (6) at car (1) top, be arranged on the D pulley (7) of hoistway bottom, be arranged on the E pulley (8) of car (1) bottom, the F pulley (9) that is arranged on the hoistway bottom is connected with the swelling device (11) that is arranged on the hoistway bottom with the G pulley (10) that is arranged on car (1) bottom.
