Description
Technical field
The utility model relates to traction class elevator, especially a kind of machine-roomless lift.
Technical background
The machine-roomless lift technology from the development of the early 1990s in last century so far, and is ripe relatively now.Being extensive use of of the gearless main frame that permagnetic synchronous motor drives or other micromainframe makes actuating device place and completely abolishes machine room in the hoistway, and effectively reduces tunnel dimension and become possibility.
Finland Kone Oy has applied for being called the patent of the machine-roomless lift of " traction rope wheel type elevator " by a key name, and (patent No.: 94106597.9), it adopted exclusive flat actuating device in 1994.Its shortcoming is: the weight of car, counterweight, driving host all acts on the guide rail, and the stressing conditions of this guide rail is poor, causes danger easily; The hitch point of car, the center of gravity of car always exist and depart from, and car is that the side cantilever structure is subjected to unbalanced torque when hanging weight.Above-mentioned 2 make it be restricted in load-carrying, can't tackle the product that heavy or car include bigger decoration weight, and the stability of car also can be affected comparatively speaking.
OTIS has invented a kind of machine-roomless lift of steel band traction, preferably resolves the problems referred to above.But the mode of steel band traction is also brought some problems, and as a kind of new riser cable, the checking of the accordance of its safety, national standard etc. also needs the certain hour check such as the steel band traction.And the steel rope technology is that the elevator industry technology is the most general, the most ripe, and steel band drags traction and is pulled on the gordian technique such as actuating device with round rope very large difference is arranged.
Patent CN03267908.4 discloses a kind of machine-roomless lift, and its constructional feature is to adopt the main frame with two traction sheaves.But because the restriction of motor development level, the exploitativeness of motor is poor, and the structure of car, counterweight implements also relatively difficulty.
For a kind of machine-roomless lift, how on the basis of traditional round steel rope traction, to be optimized make car center of gravity, guide surface (car guide rail plane), to lift that the plane three overlaps be the target that elevator industry is explored always.
Summary of the invention

Main technical schemes of the present utility model is: a kind of machine-roomless lift, comprise haulage cable, the car that moves along the cage side guide rail, the counterweight that moves along the counterweight guide rail, and the actuating device that is located at the band traction sheave at elevator hoistways top, actuating device is located on the counterweight mobile route, on car, be symmetrical arranged the car pulley near both sides cage side guide rail, the rotation axis of traction sheave and car pulley is parallel to each other, the line of centers of traction sheave Width is positioned on the plane that the cage side guide rail formed, and connects the plane separated into two parts that the described steel rope of traction sheave and car pulley is formed by the cage side guide rail.
Actuating device is installed on two guide rails of counterweight and the close car guide rail to heavy side, and is stressed more even, so both guaranteed bigger load-carrying capacity, makes car stressed evenly again, moves more steady; Traction sheave and car pulley are positioned on the car guide surface substantially, and haulage cable is distributed in guide surface side-by-side mounting car, and the center of gravity of car, guide surface, traction heart three overlap like this, make cage operation more steady.
As a kind of prioritization scheme, described car pulley is one group or two groups, is symmetricly set on the both sides that described cage side guide rail is formed the plane, and described steel rope is two groups, forms the both sides, plane from the cage side guide rail and connects described traction sheave and car pulley respectively.Haulage cable and suspension pulley are symmetrically arranged two groups like this, have increased the suspension area, make more balance of its traction meeting.
Described car pulley is located at the top or the bottom of car.Be located at the top, the convenient for maintaining operation is placed on the bottom, can make full use of existing hoistway.
Described traction sheave is provided with nicked steel rope traction grooving.Can play directional tagging to steel rope, staggered displacement influences balance when preventing to move.
Described counterweight is provided with one group or two groups of counterweight diversion sheaves.Be convenient to haulage cable on traction sheave, divide around, prevent the dislocation.
The plane of rotation of described counterweight diversion sheave is vertical with car side wall or acutangulate.Can reduce dislocation and vibration that the steel wire distortion produces like this, prolong useful life longevity.
Described actuating device is that synchronization gear wheel free drives towing machine.Reduce the volume and weight of actuating device, make full use of existing hoistway.
The utility model has the advantages that: make full use of the height of building hoistway and cross-sectional area, make car guide surface, lift plane, center of gravity and overlap, the support of actuating device is firm, stressed evenly, both can guarantee bigger load-carrying capacity, and make cage operation more steady again.Adopt the technical solution of the utility model, can easily realize the ratio of hanging of 2: 1,3: 1 or 4: 1.
