Description of drawings
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further detailed explanation:
Fig. 1 is the block diagram of lift appliance main portion of the present invention;
Fig. 2 is the birds-eye view of lift appliance of the present invention at hoist trunk.
The specific embodiment
Referring to shown in Figure 1, elevator without machine room of the present invention comprises hoist trunk 1, car 4, counterweight 7 or the rope tension device that in hoist trunk 1, goes up and down, the actuating device 2 that has drive pulley 3 and said car 4 is gone up and down.
A kind of embodiment preferably is to adopt microscler actuating device, and promptly the axial dimension of actuating device 2 is bigger than the diameter of drive pulley 3, drive pulley 3 basic and adjacent car 4 edge-perpendicular, and drive pulley 3 is not overlapping in the projection of up-down direction with car 4.The brake equipment 16 of actuating device 2 can be arranged on the direction opposite with drive pulley 3.The rope 13 of lift appliance can adopt diameter to be not more than the rope of 8mm; If drive pulley 3 diameters are less than or equal to 40 with rope 13 diameters ratio; Then the diameter of the width of actuating device 2 and drive pulley 3 thereof can design very for a short time, can ignore the influence of shaft width.
Actuating device 2 is arranged on top layer hoist trunk upper space with drive pulley 3, and overlapping in the projection section of up-down direction with elevator cage door machine device 11.And actuating device 2 is not overlapping in the projection of up-down direction with car 4 tops, is arranged on the outside of car 4 top guardrails.Drive pulley 3 and adjacent car 4 edge-perpendicular.Rope 13 extends below to sedan-chair return pulley 5 from a side direction of drive pulley 3, and walks around sedan-chair return pulley 5 upward to fag end mount pad 14; Rope 13 extends downward weighting distribution wheel 6 from the opposite side of drive pulley 3.Rope 13 is walked around weighting distribution wheel 6 and is arrived weight guide erecting frame 9.Actuating device 2 is installed on the weight guide erecting frame 9.
As shown in Figure 2, actuating device 2, drive pulley 3, counterweight 7 are positioned at side the place ahead of car 4.The axial dimension of actuating device 2 is big than the drive wheel diameter, and actuating device 2 is long strip type structures.Rope 13 diameters of lift appliance of the present invention are not more than 8mm, and drive pulley 3 diameters compare less than 40 with rope 13 diameters.The brake equipment 16 of actuating device 2 is arranged on the opposite location with drive pulley 3, and is positioned at the other end of actuating device 2.Weight guide erecting frame 9 is positioned at the top of weight guide 8, actuating device 2 be directly installed on it above.
The cage door machine device 11 of elevator and layer door gear 12 generally occupy a part of sectional area of hoist trunk 1, and especially its both sides at lift car 4 occupy many spaces.Its size that occupies is approximately about 300mm, and is as shown in Figure 2.The area that shaded area a takies for them among the figure.Therefore, the present invention makes full use of this area, and actuating device 2 parts are arranged in the zone of this area.When the elevator load carrying ability increases, only need to increase the axial dimension of actuating device 2.The size part that actuating device 2 increases can be arranged in the shaded area a, thereby actuating device does not influence the service clearance at car 4 tops simultaneously to the influence that the hoist trunk area of elevator has no yet.
Actuating device 2 is not overlapping in the projection of up-down direction with the maintenance plane (shaded area b) at lift car 4 tops, so the maintenance area size at lift car 4 tops can accomplish it is the area at whole carriage 4 tops.Car top guard 10 is along three limits of shaded area b and form the space of maintenance.So the maintainer stands in and in the maintenance plane of car top actuating device keeped in repair and maintains very convenient, there is not any work blind area in the parallel sided of the axis of actuating device and car in addition.
The maintenance plane that the maintainer keeps in repair and maintains actuating device, shadow region c as shown in Figure 2.Because the drive pulley 3 of actuating device, the brake equipment 16 of actuating device 2; (shaded area c) can operate them easily in the maintenance plane; Therefore to the care and maintenance work of actuating device 2, drive pulley 3 and brake equipment 16, there is not any work blind area.
Because the axial dimension of actuating device 2 is big than the diameter of drive pulley 3; And drive pulley 3 diameters compare less than 40 with rope 13 diameters; Therefore actuating device 2 can be made long strip type; The radial dimension of actuating device 2 is little, axial dimension is long, height dimension is little, thereby makes that the headroom height influence of 2 pairs of hoist trunks 1 of actuating device is less, even might have no influence; The cross-sectional area of 2 pairs of elevator lifting channels 1 of actuating device influence simultaneously is little.Counterweight in this embodiment also can be replaced by the rope tension device.
As shown in Figure 2, the center of the suspension center of car 4 through car 4, so the front and back unbalance loading of car guide rail 15 is smaller is good thereby car is led the wear pattern of boots.
Certainly, another kind of embodiment is the actuating device that adopts flat type, and drive pulley 3 is arranged in the position near lifting channel wall, and is substantially parallel with adjacent car 4 edges.This embodiment also can guarantee not influence fully the service clearance at car 4 tops, and has utilized the space of cage door machine device 11 tops.But the height of the actuating device of flat type is higher, and the overhead height that possibly need to increase hoist trunk 1 causes this mode possibly not to be suitable for the elevator of little load carrying ability to satisfy the safety of elevator operation.For the elevator of little load carrying ability, if adopt rope tension device rather than counterweight, the cross-sectional area of the hoist trunk 1 that so this embodiment is required can be done forr a short time.
Actuating device 2 is overlapped with cage door machine device 11 in the present invention; So the absciss layer doorway is nearer; Especially a kind of embodiment before, the rear side of actuating device 2 faces the lifting channel wall of hoist trunk 1 top layer, on this lifting channel wall, reserves a maintenance and uses opening; This opening will can be used for the maintenance to the parts of actuating device rearward position, perhaps in case of emergency at the actuating device rear side turning gear will be installed and carried out the emergency relief operation.
