Description
Technical field
The present invention relates to a kind of elevator without machine room.
Background technology
In the elevator that the tradition hauling block drives, the Machine Room of actuating device and control convenience often occupies most of space of the required building of elevator, and the Machine Room be furnished with many restrictions.Influence the utilization in space of building and attractive in appearance so on the one hand, increase the expense of building on the other hand.Along with the appearance of machine-roomless lift technology, the existing problem of elevator that traditional hauling block drives has obtained solution.Chinese invention patent specification sheets CN1038243C (May 6 1998 day for announcing) discloses a kind of machine-roomless lift (referring to Fig. 4 and shown in Figure 5).This lift appliance is not provided with the Machine Room, and the actuating device of elevator is arranged on the top of elevator lifting channel.
In aforesaid elevator without machine room, because the actuating device of elevator is arranged in the hoist trunk of elevator, therefore the fitting operation to actuating device must carry out in hoist trunk, and it is wasted time and energy.Actuating device can not keep in repair and maintain in the face of the part of lifting channel wall.And to the maintenance of actuating device and maintenance also unusual trouble, the elevator faults elevator occurring can not normally move, and then the maintenance of actuating device and maintenance just can not.Have only program like this, make elevator run to the top layer of hoist trunk, just can carry out the maintenance and the maintenance of actuating device by complexity.It is also relatively more difficult in addition elevator device to be implemented the emergency relief operation.For example when unexpected fault causes elevator out of service, need operate, can only outside hoist trunk, utilize the complicated mechanism of a cover to finish like this actuating device.Because actuating device is arranged in the hoist trunk, so actuating device will increase the sectional area of hoist trunk, thus the increase building cost.For actuating device and control setup are overhauled, care and maintenance, often need a cover complicated apparatus to guarantee the safety of operating personal, thereby increase the complexity of elevator cost and elevator device.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of elevator without machine room, and it is simple in structure, and cost is low, is convenient to safeguard and maintenance.
For solving the problems of the technologies described above, elevator without machine room of the present invention, comprise hoist trunk, the car of lifting and counterweight in hoist trunk, have drive pulley and make the actuating device of described car lifting, volume hangs over described drive pulley, rope between car and the counterweight, and be located at the opening of hoist trunk top layer layer door top hoist trunk antetheca, described actuating device is arranged in the opening of this hoist trunk antetheca, wherein, the driver element of actuating device is arranged in this opening fully, and drive pulley partly or entirely is arranged in this opening, and drive pulley is parallel with lifting channel wall; Actuating device and car are not overlapping in the projection of lifting direction, the part that is positioned at hoist trunk with top layer layer door the lifting direction to be projected to small part overlapping; Traction ratio is 2:1.
Because adopt said structure, elevator without machine room of the present invention has following beneficial effect:
1, can described actuating device be overhauled, maintain and safeguard by the opening of described top layer layer door top hoist trunk antetheca, very convenient.
2, actuating device does not influence sectional area, headroom height and the pit depth of hoist trunk, can reduce building cost.
3, do not need independent machine room, thereby can save space, and effectively utilized very much space.
4, at the top layer layer door place of described hoist trunk elevator maintenance, maintenance and test operation platform can be set, on this service platform, overhaul, care and maintenance operation, operating personal is as safe as a house so on the one hand, and the system architecture of lift appliance is simpler on the other hand, cost is lower.
5, all external force of bearing of elevator without machine room of the present invention act on the wall of hoist trunk, thereby have reduced the guide rail requirement of strength to car and counterweight.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the block diagram of elevator without machine room main portion of the present invention;
Fig. 2 is the birds-eye view of elevator without machine room of the present invention at hoist trunk;
Fig. 3 is elevator without machine room of the present invention is seen the main portion of Fig. 1 from Room reveal a block diagram;
Fig. 4 is the block diagram of existing elevator without machine room main portion;
Fig. 5 is the birds-eye view of existing elevator without machine room at hoist trunk.
The specific embodiment
As shown in Figure 1, in a kind of embodiment of elevator without machine room of the present invention, actuating device 2 and drive pulley 5 are arranged in the top opening 19 of top layer hoist trunk antetheca 15 (in conjunction with shown in Figure 3), so actuating device 2 and drive pulley 5 do not influence the headroom height of lift appliance lifting.Wherein, the driver element of actuating device 2 is arranged in this opening 19 fully, and drive pulley 5 partly or entirely is arranged in this opening 19, and drive pulley 5 is parallel with lifting channel wall.
Actuating device 2 is not overlapping in the projection of lifting direction with car 9, the part that is positioned at hoist trunk 1 with top layer layer door 17 the lifting direction to be projected to small part overlapping; Traction ratio is 2:1.
Two leading sheaves 7,8 are set above described actuating device 2, and these two leading sheaves 7,8 are supported by bearing beam 16.Rope 11 extends to leading sheave 7 from a side direction of drive pulley 5, extends downward sedan-chair return pulley 12 around leading sheave 7; Rope 11 extends upwardly to leading sheave 8 from the opposite side of drive pulley 5, extends downward weighting distribution wheel 13 around leading sheave 8.The below of weighting distribution wheel 13 connects counterweight 14.
Actuating device 2 is installed in adapter plate 3 times, is connected with vibration-proof rubber 4 by adapter plate 3.Vibration-proof rubber 4 is installed in the below of bearing beam 16.Because actuating device 2 is to be subjected to pulling force upwards, and is delivered to bearing beam 16 by vibration-proof rubber 4, vibration-proof rubber 4 can play the effect of vibration damping like this.
In hoist trunk 1, car 9 is along car guide rail 10 liftings.
Referring to Fig. 2, elevator control gear 6 is arranged on a side of actuating device 2, and is arranged in the top opening 19 of hoist trunk antetheca 15.Side at hoist trunk 1 close hoist trunk antetheca 15 is provided with three bearing beams 16, and leading sheave 7,8 is installed in the top of bearing beam 16 respectively.Leading sheave 7,8 and bearing beam 16 are positioned at the zone outside of car upper guardrail 21 at described car 9 lifting direction projections with car projection overlapping region.
In hoist trunk 1, counterweight 14 is along weight guide 18 liftings, and the place ahead, left side of 14 of counterweights and hoist trunk 1.
Can be clear that more that by Fig. 3 actuating device 2 and elevator control gear 6 are positioned at the opening 19 of hoist trunk 1 top layer antetheca 15.
At the top layer layer door place of described hoist trunk one elevator maintenance, maintenance and test operation platform 20 are set like this, service personnel can be climbed up service platform 20 by ladder 22, overhauls, maintenance and test job.Because service platform 20 does not influence elevator passenger turnover lift car, so this platform can be provisional, also can be nonvolatil.
Elevator without machine room of the present invention is arranged on actuating device 2 and drive pulley 5 in the opening 19 of hoist trunk 1 top layer antetheca 15, and elevator control device 6 also is provided with wherein.Can provide a kind of hoist trunk cross-sectional area the little and little elevator without machine room of hoist trunk headroom height on the one hand; The more existing elevator without machine room of this on the other hand lift appliance has maintenance, maintenance and test easily, and the very high characteristics of safety.
