The specific embodiment
With reference now to accompanying drawing, the preferred embodiments of the present invention is described.
Fig. 3 shows the Machineroom-less elevator system that constitutes according to the present invention.
Machineroom-less elevator system is the elevator device that does not have the conventional machine room that is used for elevator machine, and this Machineroom-less elevator system is located at the upper space of vertical shaft usually, and lift car 22 and counterbalanced weight 24 pass this vertical shaft and advance.In this vertical shaft, lift car 22 can vertically pass the belt pulley 28 of counterbalanced weight 24 and the pulley (not shown) of elevator machine 70 by main rope or belt 30, and main rope or belt 30 remains on (these belt pulleys mode of hanging below 11 is attached on the lift car 22) around the belt pulley 11 of lift car 22.Elevator machine carries the top load of elevator devices by the main rope 30 that remains on its pulley top.
According to the present invention, the elevator machine supporting component 50 that is used to support this elevator machine 70 is installed in relative wall 38 (only illustrating), and these relative walls 38 limit this vertical shaft near the space above the counterbalanced weight 24.
Fig. 4 shows the enlarged perspective of mechanical support assembly 50, and the pulley of wherein shown elevator machine 70 is in the front of elevator device.
Mechanical support assembly 50 comprises main frame 54 and is parallel to the subframe 52 that main frame 54 extends.Two frameworks 52 and 54 two ends all are positioned on the groove 40, and groove 40 forms at relative wall 38, and relative wall 38 limits these vertical shafts.
This creativeness mechanical support assembly 50 also comprises connector 64a to 64d, carriage 62a to 62d and absorption of vibrations pad 92 and 94 (see figure 5)s except main frame 54 and subframe 52.
Referring to Fig. 5, the figure shows the decomposition diagram of mechanical support assembly 50.
Main frame 54 comprises two outer beams 53 and rectangular frame, and this rectangular frame supports between the beam 53 and by beam outside these two 53 outside two.The a pair of vertical member 56 of this rectangular frame is fixed to the inner of two outer beams 53.The outer end of two outer beams 53 is positioned on the groove 40 of hoistway wall 38.
This rectangular frame (except a pair of vertical member 56) also comprises upper member 58 and lower member 60, and has the size that is enough to provide a space, and elevator machine 70 can be contained in this space.Two upper ends of vertical member 56 are linked together by upper member 58, and two lower ends of vertical member 56 interconnect by lower member 60.A pair of vertical member 56, upper member 58 and lower member 60 form this rectangular frame by this way.This framework has rectangular generally profile, and this profile can be surrounded elevator machine 70.
Elevator machine 70 is fixed to this rectangular frame with the lower end in the top, and is positioned at the inner space of this rectangular frame.The upper end of elevator machine 70 is attached to upper member 58 by analog bracket 84 (being shown in Fig. 6), and the lower end snail of elevator machine 70 ties and receives lower member 60.
According to the present invention, determine the upright position of rectangular frame with respect to outer beam 53 so that the pulley center that is installed in the elevator machine 70 on the rectangular frame with the center of the outer beam 53 of vertical direction on identical level.
And, can use other paired outer beam, rectangular frame is firmly grasped more firmly (being shown in Fig. 5) except an external beam 53, these outer beams extend being parallel to an external beam 53, as shown in the figure.In this case, can adopt with other outer beam to cooresponding other rectangular frame.
Subframe 52 is provided, and this subframe is parallel to main frame 54 and extends.Subframe 52 separates with horizontal direction and main frame 54.In a preferred embodiment of the invention, subframe 52 is long one-piece beam.Outside growing than beam 53, the specification of subframe 52 is identical with the specification of outer beam 53.The two ends of subframe 52 also all are positioned on the groove 40 of the relative wall 38 that limits vertical shaft, and fixed thereon.
A plurality of connector 64a to 64d are arranged between subframe 52 and the main frame 54, so that they are linked together.As shown in the figure, connector 64a to 64d separates each other, so that the pulley of elevator machine 70 can be positioned among these at interval.
For the outer beam 53 of the drag with increase is provided, adopt a plurality of L shaped carriage 62a to 62d so that rectangular frame is connected with subframe 52, the drag of this increase at the pulley that is added in elevator machine 70 by elevator device (from a kind of structure, in this structure, the rectangular frame that only has an external beam 53 to support between them) moment of torsion that load caused on, elevator device comprises lift car and counterbalanced weight etc.In this preferred embodiment, bracket 62a and 62b are connected to subframe 52 with the upper end of vertical member 56, and bottom bracket 62c is connected lower member 60 with 62d with subframe 52.
Referring to Fig. 5 and Fig. 6, the pad 94 that is used to absorb the vertical shake of mechanical supporting component 50 be positioned at the outer end of two outer beams 53 of the two ends of subframe 52, main frame 54 and transom 64a and 64d below.But, will be appreciated that pad 94 also can only be installed in below the outer end of outer beam 53.
And the pad 92 of horizontal vibration that is used to absorb mechanical supporting component 50 is between mounting structure 90 and 91 and between mounting structure 90 and 96. Mounting structure 90,91 and 96 has the stayed surface that extends with downward direction.Though preferred mounting structure 90 is fixed to connector 64a and 64d, they also can join subframe 52 or outer beam 53 to. Mounting structure 90 and 96 remains on respectively on the bottom of groove 40.
In a preferred embodiment of the invention, pad 92 and 94 usefulness rubber are made.
Referring to Fig. 6, a plurality of metal sheets 80 can be located at the outer end of two ends of subframe 52, two outer beams 53 and connector 64a to 64d below, to regulate the height of main frame 54 and subframe 52.
As shown in Figure 6, the pulley of elevator machine 70 is centered close on the level identical with the level of outer beam 53.This is the moment of torsion that is added on the main frame 54 in order to reduce.
Industrial usability
According to the present invention, the top and bottom of elevator machine are fixed to rectangular frame.And elevator machine is positioned at the inside of rectangular frame.So, elevator machine more stably can be supported.
And, owing to extend in parallel and cross-divided each other two frame supported elevator machines,, just can guarantee the more stable case of elevator machine among the present invention so compare with the elevator machine of use single-beam in the prior art.
Moreover because being centered close on the level identical with the level of outer beam of the pulley of elevator machine, so this beam will be subjected to less moment of torsion, the load that this moment of torsion is added in by elevator device on the pulley of elevator machine is caused.
At last, being connected with between rectangular frame of realizing by L shaped carriage and the subframe helps whole assembly and resists moment of torsion.
Though by specific embodiment the present invention is illustrated and describes, those of skill in the art are clear can to exchange and revise the present invention, and does not break away from the scope of the present invention that is limited by appending claims.
