Fig. 1-Fig. 3 is the schematic diagram being indicated to the structure of elevator of the present utility model.
As shown in Figure 1-Figure 3, elevator possesses:Car (CAR) 1, for occupant ride, carries out elevating movement in hoistway;It is right Weight (C/W) 2, carries out elevating movement in hoistway;Traction machine 3, in computer room replace both set elevator geared machine and structure As gearless type, possess the traction sheave 30 for being wound with rope 8, traction power transmitted via rope 8 to car 1 and counterweight 2, Car 1 is set relatively to be lifted in hoistway with counterweight 2.
In addition, elevator is provided with spandrel girder 4 in computer room internal frame, the traction machine is placed with the spandrel girder 4 and described later Directive wheel.
In addition, the elevator is provided with car frame (eliminating overall diagram) in hoistway, the car frame is to above-mentioned car 1 Carried, including above the car and along the horizontally extending upper beam in the switch direction (X-direction in Fig. 2) of car door 11st, the underbeam positioned at the column of car both sides and below car, is formed as the frame-shaped for surrounding car;
In elevator of the present utility model, it is provided with as rope sheave:The traction sheave 30;Directive wheel 40, is provided only with 1 It is individual, the spandrel girder 4 is installed on, one end of the rope from the traction sheave 30 is guided to counterweight-side;Counterweight sheave 20, the top of the counterweight is configured at, receives one end of the rope from the traction sheave 30 and is wound;Car sheave 10,1 is provided only with, the upper beam of the car frame is configured at, receives the other end of the rope from the traction sheave and is rolled up Around rope is hung on the traction sheave 30, the car sheave 10, the directive wheel 40 and the counterweight sheave 20, by wiring Than being set to 2:1.So-called wiring refers to the peripheral speed or rope movement velocity and car speed of traction sheave than also referred to as traction ratio The ratio between.
The car sheave 10 is arranged at the upper beam of car frame via car sheave beam 12, and the car sheave beam is configured to, The car sheave beam 12 is supported, in the either above or below of the upper beam 11 of car frame, along the extension of the upper beam Direction and configure, it is overall overlapping with the upper beam 11 during vertical view.That is, bearing of trend and the institute of the car sheave beam 12 The bearing of trend for stating upper beam 11 is identical, and car sheave beam 12 is totally overlapped on upper beam 11, in the absence of relative to upper beam 11 to The part that (Y-direction) orthogonal with bearing of trend stretches out.
The car sheave 10 possesses rotary shaft (not shown), the axial direction of the rotary shaft and the bearing of trend of car sheave beam (X-direction) is orthogonal.
In addition, elevator is in computer room, as shown in figure 4, traction machine is installed on the spandrel girder 4 via support fixed station 5.This Outside, the support fixed station has:Lower support fixed station 51, the upper of the spandrel girder is arranged at along the spandrel girder 4 extension Surface;Intermediate stand fixed station 52, is arranged at the upper surface of the lower support fixed station 51;And upper frame fixed station 53, if It is placed in the upper surface of the intermediate stand fixed station 52.In the support fixed station, the traction machine 3 is configured via pedestal 31 In the upper frame fixed station 53, the directive wheel is installed on the lower support fixed station.
In the example shown in Figure 4, the lower support fixed station 51, the intermediate stand fixed station 52 and the lower support Fixed station 53 is respectively two ribs that are horizontally extending and being parallel to each other, the ribs of the lower support fixed station 51 and institute The ribs for stating intermediate stand fixed station 52 is configured across, also, the ribs of the intermediate stand fixed station 52 with it is described The ribs of lower support fixed station 53 is configured across.It is preferred that intersecting in an orthogonal manner.
Moreover, it is also possible to be, being provided between the lower support fixed station 51 and the upper surface of the spandrel girder 4 has The vibration isolation member 6 of some strength, such as rubber blanket.
In addition, in the utility model, directive wheel 40 is configured in position of the cornerite less than 180 ° for making traction sheave 30.Its In, cornerite refers to that rope bypasses the radian of traction sheave.
In the elevator of said structure, the sedan-chair including the car frame, the car sheave, the car sheave beam Both the requirement for the safety tongs that elevator possesses had been set described in the total load satisfaction of railway carriage or compartment.
Below, the effect to the elevator of said structure is illustrated.
In elevator of the present utility model, as the elevator of gearless type, there is provided a car sheave 10 and a guiding Wheel 40,2 are set to by wiring ratio:1, compared with being provided with the conventional elevator of 2 car sheaves, 1 car sheave is reduced, because This, can reduce structural element corresponding with 1 car sheave, and can be formed shortlyer for configuring car sheave Car sheave beam, as a result, the load of car is correspondingly reduced.In addition, though adding a guiding compared with conventional elevator Wheel, but as described above, directive wheel be disposed on the spandrel girder in computer room without being disposed on car, therefore, directive wheel Set to car increase need carry load.Therefore, overall as car, load is reduced, therefore, it is possible to continue to make With the safety tongs both set.
In addition, in elevator of the present utility model, the car sheave beam being supported to car sheave is in the vertical direction It is overall overlapping with the upper beam of car frame, do not possess the part stretched out laterally relative to upper beam.Thus, with it is conventional shown in Fig. 6 Elevator is such, car sheave beam 12 ' is arranged obliquely relative to the upper beam 11 ' of car frame and stretched relative to upper beam from laterally The structure gone out is compared, the spaces of the both sides in the direction orthogonal with bearing of trend of the upper beam of car top of the present utility model not by Car sheave beam is taken, and more working spaces can be ensured in car top.
In addition, in elevator of the present utility model, the support for 3 support fixed stations that traction machine overlaps via possessing Fixed station 5 is installed on the spandrel girder.
In addition, in elevator of the present utility model, support fixed station is overlappingly configured with lower support from bottom to top and successively Fixed station 51, intermediate stand fixed station 52 and upper frame fixed station 53 are defined high thereby, it is possible to have support fixed station Degree, to ensure the space for configuring the components such as traction machine.Also, by make lower support fixed station 51, intermediate stand fixed station 52 and Upper frame fixed station 53 is configured with intersecting, especially by intersecting in an orthogonal manner, can make each support fixed station Between configuration more consolidate.
In addition, in elevator of the present utility model, being provided between lower support fixed station and the upper surface of spandrel girder anti- Shake component, the vibration produced during thus, it is possible to mitigate traction transmission.
In the elevator of said structure, the car total load including car frame, car sheave and car sheave beam is (certainly Weight and load-carrying) requirement for both setting the safety tongs that elevator possesses is disclosure satisfy that, it therefore, there is no need to change safety tongs.
More than, enumerate preferred embodiment and the elevator involved by the utility model is illustrated, still, these implementations Mode is intended only as illustrating what is enumerated, is not intended to limit the scope of utility model.New embodiment can be various with other Mode is implemented, in the range of the purport of invention is not departed from, can carry out it is various omit, displacement, change.These embodiments And its deformation is included in the scope and purport of invention, the scope and its equivalent scope being also contained in described in claim It is interior.
