Abstract
The utility model discloses a machine-room-less elevator car frame with oblique beam layouts. The machine-room-less elevator car frame comprises two stand columns, a car frame upper girder and a car frame lower beam. The two stand columns are located on the middle portion of the left side and the right side of a car; the car frame upper beam is located on the middle portion of the top surface of the car; and the car frame lower beam is located on the middle portion of the bottom surface of the car. Both ends of the bottom of the car frame lower beam are provided with car bottom sheave beams for fixing two diversion sheaves. One guide shoe matched with a guide rail is fixed at each end of the car frame upper beam. Safety tongs and one guide shoe are fixed at each end of the car frame lower beam; and the safety tongs and the guider shoe are matched with the guide rail. A gravity-center line of the two diversion sheaves and a center symmetry line of the car frame lower beam are arranged on the same plane in an intersection manner, and both penetrate through the gravity center of the car. The gravity center line of the two safety tongs coincides with the center symmetry line of the car frame lower beam. When the car is urgently braked, braking force can be applied on the gravity center of the car, so that a braking process is safer and more reliable; and meanwhile sheave force applied on the car gravity center is more stable when the car is operated normally.
Description
Technical field
The utility model relates to a kind of elevator car frame cant beam arrangement apparatus, relates in particular to the elevator car frame that a kind of machine room cant beam is arranged.
Background technology
At present, known room-free elevator car frame arrangement is to be illustrated in figure 1 straight beam to arrange, comprises towing machine 3, the control system that is positioned at hoistway top, the car 10 that is positioned at hoistway and counterweight 13, diversion sheave 8.The outer sedan-chair frame that is provided with of car 10 wherein, this sedan-chair frame is by two root posts 11 that are positioned at car 10 left and right sides middle parts and be positioned at the sedan-chair frame upper beam 9, car frame underbeam 14 at car 10 middle parts, above and below and form for the rope sheave beam 16 of diversion sheave 8 at the bottom of fixing sedan-chair.Sedan-chair frame upper beam 9 two ends be fixed with separately one with guide rail (not shown in FIG.), coordinate lead boots 6, safety tongs 15 coordinated with the guide rail that is positioned at homonymy of each self-retaining of two ends under car frame underbeam 14, as can be seen from Figure 1, the line of safety tongs 15 is without the center of gravity of car 10.Therefore, when elevator emergency brake, the center of gravity of car 10 is not also on the line of safety tongs 15, but braking force acts on safety tongs 15, thus, this braking force can produce the power of toppling to car 10, when this power be greater than sedan-chair frame and car 10 be connected power the time, car 10 just has the danger of toppling.
The utility model content
For above-mentioned prior art, for overcome existing machine room sedan-chair frame when braking braking force not in the car center of gravity, the dangerous problem of toppling is arranged, the elevator car frame that the utility model provides a kind of machine room cant beam to arrange, when the car emergency braking, Braking is in the car center of gravity, more safe and reliable during braking.When car normally moves, rope sheave power, also in the car center of gravity, makes the elevator operation more steady, the safety while having increased elevator emergency brake simultaneously.
In order to solve the problems of the technologies described above, the technical scheme that the elevator car frame that the utility model machine room cant beam is arranged is achieved is: the sedan-chair frame consists of with the sedan-chair frame upper beam and the car frame underbeam that are positioned at car end face and middle part, bottom surface two root posts of the left and right side middle part that is positioned at car; The two ends, bottom of described car frame underbeam are equipped with rope sheave beam at the bottom of the sedan-chair for fixing two diversion sheaves; The two ends of described sedan-chair frame upper beam be fixed with respectively one with guide rail, coordinate lead boots, the two ends of described car frame underbeam are fixed respectively a safety tongs coordinated with guide rail and are led boots; What the center of gravity line of two diversion sheaves and car frame underbeam centre symmetry line intersected is arranged in same plane, and the center of gravity line of two diversion sheaves and car frame underbeam centre symmetry line are all by the center of gravity of car.
The elevator car frame that the utility model machine room cant beam is arranged, wherein, the center of gravity line of two safety tongss overlaps with the centre symmetry line of car frame underbeam.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is angled layout on the sedan-chair baseplane by diversion sheave at the bottom of sedan-chair and safety tongs, like this at the bottom of sedan-chair the line of the line of diversion sheave 8 and safety tongs all by the center of gravity of car, when the car emergency braking, Braking is in the car center of gravity, more safe and reliable during braking.When car normally moves, rope sheave power is also more steady in the operation of car center of gravity simultaneously.
The accompanying drawing explanation
Fig. 1 is a kind of room-free elevator car frame schematic diagram in prior art;
Fig. 2 is the elevator car frame schematic diagram that the utility model machine room cant beam is arranged;
Fig. 3 is the planar view of the relative hoistway position of elevator car frame of the utility model machine room cant beam layout.
In figure:
The secondary fag end of 1-, the 2-steel rope, the 3-towing machine, the 4-guide rail, the 5-fag end, 6-leads boots, 7-diversion sheave axle, 8-diversion sheave, 9-sedan-chair frame upper beam, 10-car, 11-sedan-chair frame column, 12-counterweight diversion sheave, 13-counterweight, 14-car frame underbeam, 15-safety tongs, 16-sedan-chair frame rope sheave beam.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in further detail.
As shown in figures 1 and 3, usually the crane bridging system of lift car comprises towing machine 3 and the control system that is positioned at hoistway top, be positioned at the car 10 of hoistway and counterweight 13 etc., also show the fag end 5 and the secondary fag end 1 that are positioned at car 10 tops in Fig. 3, be positioned at the counterweight diversion sheave 12 of car bottom for driving counterweight 13, the outer sedan-chair frame that is provided with of described car 10.
As shown in Figures 2 and 3, the elevator car frame that the utility model machine room cant beam is arranged, described sedan-chair frame consists of with the sedan-chair frame upper beam 9 and the car frame underbeam 14 that are positioned at car 10 end faces and middle part, bottom surface two root posts 11 of the left and right side middle part that is positioned at car 10, the two ends, bottom of described car frame underbeam 14 are equipped with rope sheave beam 16 at the bottom of the sedan-chair for fixing two diversion sheaves 8, the two ends of described sedan-chair frame upper beam 9 be fixed with respectively one with guide rail 4, coordinate lead boots 6, the two ends of described car frame underbeam 14 are fixed respectively a safety tongs coordinated with guide rail 4 15 and are led boots, two diversion sheaves 8 are arranged at the bottom of sedan-chair on diversion sheave beam 16 by the diversion sheave axle 7 perpendicular to sedan-chair frame rope sheave beam 16, what the center of gravity line of two diversion sheaves 8 and car frame underbeam 14 centre symmetry line intersected is arranged in same plane, the center of gravity line of two diversion sheaves 8 and car frame underbeam 14 centre symmetry line are all by the center of gravity of car 10, because the center of gravity line of two safety tongss 15 overlaps with the centre symmetry line of car frame underbeam, therefore, at the bottom of sedan-chair, diversion sheave 8 can be avoided the safety tongs position, the traction when braking force while making elevator brake and normal operation can be passed through the car center of gravity, more steady while making the elevator operation, also more reliable and secure during emergency braking.
