Description
Technical field
The utility model relates to elevator technology field, is specifically that one is specially adapted to machine-roomless lift, and the while is also applicable to small room or has the elevator hoistways arrangement structure of machine room elevator.
Background technology
Traditional steel rope towed elevator, safety standard specifies that the diameter ratio of traction sheave, suspension sheave and steel rope needs >=40 times, also at least >=25 times of home lifts, due at least 8mm of wirerope diameter, cause traction sheave and suspension sheave diameter larger, in the time that elevator hoistways is arranged, wheel not point-blank otherwise waste hoistway space, and cause traction steel-cable distortion, unbalance stress and wearing and tearing inequality, such as the application publication number Chinese patent application that is CN103523638A.
Also have at present the elevator arrangement of traction (steel) with traction, but it generally adopts gantry sedan-chair rack and panel construction.Although be also that heavy side towline head is arranged at below towing machine to (as the application publication number Chinese patent application that is CN102180393A), but actual enforcement is very unreasonable, car is no matter be the hang of crosshead sheave (or sedan-chair return pulley), because portal frame must be consistent with safety tongs He Daoxue center, its suspension sheave can only be setovered, not only cause car centre-of gravity shift unbalance stress, and in order to fill in addition its sedan-chair shelf structure complexity of sedan-chair return pulley, volume increase takes up room.In addition, car guide rail and counter weight guide track be not in the same side, and layout in 90 ° needs the another cage side rail brackets that increases, and increases cost and hoistway space.
Traditional knapsack posture elevator has fluid pressure type and 2 kinds of modes of steel rope traction, and the maximum defect on hydraulic pressure side top is unbalance loading wearing and tearing and power consumption, seldom adopts at present.Steel rope mode is large because hang wheel diameter, causes structure heaviness, takies the defects such as sedan-chair base space and seldom employing.
Utility model content
Technical problem to be solved in the utility model is, overcome the defect of prior art, provide a kind of by above structural advantage complementation, learn from other's strong points to offset one's weaknesses, solved preferably that said structure bulky complex, stressed unbalance loading are unreasonable, steel rope (or drawing belt) tension force inequality, wearing and tearing are uneven, the not compact defect such as take up room of structure, have layout flexible, easy for installation, structure is the elevator hoistways arrangement structure of lightweight, operation advantages such as noise is light lightly.
For solving the problems of the technologies described above, the utility model proposes a kind of elevator hoistways arrangement structure, one of drawing belt is fixed on bearing beam, towing machine is installed on bearing beam, the other end of drawing belt is tilted to lower cw and walks around being tilted to about the axis symmetry to roller after roller and cw is walked around the traction sheave of towing machine again, then vertically downward, then conter clockwise is fixed on rope hitch plate after walking around sedan-chair return pulley vertically upward and finally; To roller and to reconnecting; Sedan-chair return pulley is connected with Knapsack-rack; Described traction sheave, be same straight line to the cross central line of roller, counterweight, sedan-chair return pulley, the projection of Knapsack-rack in horizontal surface; Car is installed on Knapsack-rack.
Adopt after said structure, compared with prior art, the utlity model has following advantage: the utility model has adopted the flat and thin characteristics and advantages of drawing belt, make the traction sheave of towing machine, the diameter of roller and sedan-chair return pulley is reduced greatly, mounting structure compactness, conserve space greatly, thereby avoid the above-mentioned wheel diameter of traditional steel wire towed elevator large, needed gradient to arrange to roller or car wheel;
The utility model is fixed on the drawing belt terminating set to heavy side below bearing beam, the symmetrical vertical surface in front and back of traction sheave, the symmetrical vertical surface in front and back to the symmetrical vertical surface in the front and back of roller, sedan-chair return pulley, the symmetrical vertical surface in front and back of Knapsack-rack are same vertical surface, without deflection to an arbitrary wheel in roller, sedan-chair return pulley, not only compact conformation effectively utilizes space, and the unbalance stress and the wearing and tearing that do not exist drawing belt distortion to turn to cause;
The utility model is to tilt to be arranged symmetrically with to the drawing belt of heavy side, one that is drawing belt is fixed on bearing beam, towing machine is installed on bearing beam, the other end of drawing belt is tilted to lower cw and walks around being tilted to about the axis symmetry to roller after roller and cw is walked around the traction sheave of towing machine again, so both effectively utilized the space under towing machine vertical projection, simplify the mounting structure of the terminating set of of drawing belt, save space and convenient installation; Under counterweight is positioned at roller time, can ensures again the center of gravity of counterweight and not be offset to upper pulling force roller is suffered, counterweight does not produce side force, thereby reduces wear and noise;
The utility model adopts knapsack posture car structure, sedan-chair return pulley is installed on the collet of Knapsack-rack, the cross central line of sedan-chair return pulley, the Knapsack-rack projection in horizontal surface is same straight line, thereby avoid traditional backpacks shelf structure car deviation of gravity center center, stressed deterioration, cause car to lead boots serious wear, when operation noise large, and the easily shortcoming such as distortion of car;
Comprehensively above-mentioned, the utility model is learnt from other's strong points to offset one's weaknesses, solved preferably that existing structure bulky complex, stressed unbalance loading are unreasonable, steel rope (or drawing belt) tension force inequality, wearing and tearing are uneven, the not compact defect such as take up room of structure, there is layout flexible, easy for installation, structure is lightweight, the operation advantages such as noise is light lightly.
As improvement, car guide rail and counter weight guide track are arranged in the same side, and Knapsack-rack is led boots by car and is installed on car guide rail; Counterweight is led boots by counterweight and is installed on counter weight guide track, and like this, structure is compacter, and space availability ratio is higher.
As improvement, the first vertical line of centers of the projection of car guide rail in horizontal surface is positioned at the left side of the second vertical line of centers of the projection at horizontal surface of counter weight guide track, it is the left side that the symmetrical vertical surface of car guide rail is positioned at the symmetrical vertical surface of counter weight guide track, like this, can shorten the length of rail brackets left and right directions, thereby structure is compacter, more effectively utilize space.
