Description
Technical field
The utility model relates to elevator technology fields, and in particular to a kind of traction suspension for machine-roomless lift.
Background technique
In the prior art, in the traction suspension of machine-roomless lift, counterweight is located at the side of carriage, i.e. counterweight-side mostly
It sets, when host is arranged in well headroom, is distinguished by the different arrangement of driving host, mainly there is following four form:
1, bar shaped host, host traction sheave is consistent with carriage pulley arrangements direction, and carriage pulley is that double car roof wheels are (upper outstanding
Hang) or double car floor wheels (lower suspension), crosshead sheave (upper suspension) mode: crosshead sheave and carriage traction center (horizontal direction) it is consistent or
Deviate certain distance；Double car floor wheel (lower suspension) car floor wheels are consistent with carriage traction center or deviate certain distance.
Bar shaped host is fixed on above the main machine base above well headroom spandrel girder or at the top of carriage, counter weight guide track.Steel
Cord takes turns to car top (bottom) wheel not windup-degree from host traction, but takes turns to counterweight wheel from host traction, reverses certain angle.It compiles
Code device is located at host one end, easy to maintenance.Elevator device using steel band as traction suspension arrangement belongs to such arrangement.
2, dish-style motor, host are located at the outside of carriage unilateral side guide rail, realize traction arrangement, double car floors by double car floor wheels
When taking turns parallel with car width direction, double car floor wheels center is consistent with car guide rail center position, and double car floor wheels center is with respect to sedan-chair
Compartment guideway centreline deviates certain distance.When double car floor wheels and car width direction are not parallel, double car floor wheels center and car guide rail
There is certain angle at center.This kind of arrangement, counterweight space are very small.Traction sheave and car floor wheel and certain angle is reversed to roller.
Encoder is located at main guide rail center, and the host back side between the main guide rail back side and host traction sheave or close to well enclosure is compiled
Code device maintenance is inconvenient.Such arrangement, the cost is relatively high for counterweight.
3, routinely organic house-owner's machine is arranged at the top of spandrel girder (spandrel girder direction is shaft depth direction), generally adopts
With double car roof wheels (upper suspension) or double car floor wheels (lower suspension) form, when double car floor wheel (lower suspensions), car floor wheel and traction center
Deviate certain distance.Host outer dimension is big, and hoistway headroom height requires height, and competitiveness is low.Wirerope takes turns to car top from traction
(bottom) wheel, reverses certain angle.
4, routinely organic house-owner's machine, is arranged at the top of spandrel girder that (when counterweight side, spandrel girder direction is shaft width side
To), host traction takes turns to crosshead sheave (single or double) and does not reverse, and host passes through the guiding that is fixed on spandrel girder or main machine base
Wheel, wirerope reverse certain angle to roller.Host outer dimension is big, and hoistway headroom height requires height, and competitiveness is low.
The above conventional roomless traction system arrangement, is all counterweight side form, and host is located at top, when needs pair
When host carries out upkeep operation, since position of host machine is relatively high, operation is difficult.In addition to dish-style motor, by supervision and inspection and periodically
When machine-roomless lift uses car top as upkeep operation platform carriage fixed mechanism need to be arranged, the mechanism position in test stone requirement
Set the position for being generally located on the normal leveling of elevator top hereinafter, car top have to be lower than top layer hall door top and guarantee 300~
When the space 500mm is to facilitate host or other systems failure to cause elevator that can not move, service personnel is convenient to from this space
Escape.When elevator is in top layer operation, such as repairs host, adjustment brake, limiter of speed operation, elevator device is limited by maintenance
Electrical limitation is only capable of maintenance uplink so far position, locks carriage fixed mechanism, and operated in car top job platform, at this point,
People's elevation plane of effectively standing from car top is to host distance from bottom normally close to 2m, and host maintenance height is higher, and operation is difficult and has
Falling hazard.For dish-style motor, host is fixed on the carriage single guide rail back side, and encoder is located at rail back and host traction
Between wheel or well enclosure side, inconvenient maintenance, this another arrangement are not suitable for counterweight postposition.
Part elevator manufacturer using the third, the 4th kind of arrangement form, due to height of main frame with respect to the first arrangement
Mode is higher, host is arranged in above the spandrel girder of well headroom, by directive wheel, realizes traction arrangement, this form master
Machine with respect to the first, second scheme it is higher, host maintenance it is very inconvenient and dangerous.In addition, for long and narrow bar shaped hoistway,
I.e. shaft depth is bigger, the very narrow situation of width, such as installs elevator additional to existing building.Counterweight side is limited due to space
System, car width is generally smaller, and takes counterweight postposition arrangement, and the space limitation of counterweightless side may be implemented more
Big car width, in addition, taking counterweight postposition, crosshead sheave is located at carriage center, relatively double sedan-chair (bottom) wheels of center suspension in realization
Side-by-side mounting, car top space is bigger, facilitates maintenance, and traction center can be overlapped with guiding centre, elevator operation it is more stable and reliable,
Runnability is more preferable.The above arrangement form only has the 4th kind of mode that can realize counterweight postposition, but due to height of main frame height, maintenance master
The components such as machine and system, there are security risks, therefore, research and develop more flexible roomless traction system arrangement, very necessary.
For installing elevator additional, hoistway is usually the later period outside existing building or interior construction, when as using there is division of room, machine
Room height can be higher than it is former build, destroy it is former build style, and because original building without conveniently, safely efficiently channel to computer room
It is interior, generally take vertical ladder form to climb to attic computer room, it is very inconvenient and have and fall risk for upkeep operation, thus it is general not
Elevator is installed additional using there is computer room form to carry out existing building.
Above-mentioned Machineroom-less elevator system arrangement increases headroom height requirement, while host repairs the Dingan County Gao Youyi
Full blast danger, inconvenient maintenance, therefore it is very necessary to research and develop novel inorganic machine room-free elevator system arrangement.
