Description
Technical field: the present invention relates to a kind of jacking system, especially a kind of leading screw multiplication jacking system.
Background technology: China's car type elevator is used for the occasion of residential quarters high-rise building and public place skyscraper at present, it is larger that its load capacity designs, lifting mechanism is bulky, and with noise, and have obvious uncomfortable sensation in startup and stopped process, be especially a kind of dangerous stimulation to the bad people of heart.Such elevator is directly used in that on family's small sized multiple story building, particularly to have the user of high request for those be obviously inappropriate.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides one quick, steady, comfortable, the leading screw multiplication jacking system of noiseless, safety.
For achieving the above object, the technical solution used in the present invention is: leading screw multiplication jacking system, comprises that ball-screw, ball-screw nut, movable pulley, movable pulley frame, lower fixed pulley, movable pulley frame, upper fixed pulley, fixed pulley frame, servomotor, steel rope and car form; Servomotor is fixedly connected with ball-screw by reductor, ball-screw and ball-screw nut transmission link; Movable pulley and movable pulley frame are rotationally connected; Lower fixed pulley and fixed pulley frame are rotationally connected; Movable pulley frame is fixedly connected with ball-screw nut; One end of steel rope is adjusted bolt by steel rope and is fixedly connected with fixed pulley frame; The other end is walked around successively movable pulley, lower fixed pulley, movable pulley, lower fixed pulley, guide wheel, upper fixed pulley and is fixedly connected with car top, forms multiplication mechanism.
It is quick, steady, comfortable that the present invention has, the feature of noiseless, safety.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is block diagram of the present invention.
Detailed description of the invention:
As shown in Figure 1-Figure 3: leading screw multiplication jacking system, comprise guide rail, main support beam 2, movable pulley 3, sheave shaft 4, movable pulley frame 5, compensating groove 6, expansion bolt 7, wear pin 8, guide rail 10, lead boots 11, car 12, steel rope 13, bearing seat beam 14, bearing set 15, leading screw end clamp nut 16, elastic coupling 17, reductor 18, speed reducer output shaft 48, servomotor 19, long fixed pulley axis 20, upper fixed pulley 21, crossbeam 22, ball-screw 23, ball-screw nut 24, lower fixed pulley 25, balance wheel 27, lower fixed pulley 29, determine down slide-bar 49, bearing seat 30, fixed pulley frame 31 forms.Its middle guide 10 is fixedly connected with main support beam 2, and main support beam 2 is fixedly connected with bearing seat beam 14, and car 12 is by wearing pin 8 and leading boots 11 and be flexibly connected.Balance wheel 27 is fixed on the upper end of lower fixed pulley 25; Balance wheel seat is fixedly connected with fixed pulley frame 31; Servomotor 19 is fixedly connected with reductor 18; Speed reducer output shaft 48 is through coupler 17 and ball-screw 23 transmission links; Ball-screw 23 is rotationally connected by bearing set 15 and bearing seat beam 14; Long fixed pulley axis 20 is fixedly connected with bearing seat beam 14; Long fixed pulley axis 20 is rotationally connected with upper fixed pulley 21; Ball-screw 23 is fixedly connected with leading screw end clamp nut 16 by bearing set 15; Ball-screw 23 and ball-screw nut 24 transmission links; Ball-screw nut 24 is fixedly connected with movable pulley frame 5; Movable pulley 3 is rotationally connected with sheave shaft 4; Sheave shaft 4 is fixedly connected with movable pulley frame 5; Fixed pulley 29 is rotationally connected with fixed pulley frame 31 by lower fixed pulley axis 49; The lower end of ball-screw 23 and bearing seat 30 are rotationally connected; Bearing seat 30 is fixedly connected with fixed pulley frame 31; Fixed pulley frame 31 is fixedly connected with main support beam 2; Steel rope 13 one end are adjusted bolt 50 by steel rope and are fixedly connected with fixed pulley frame 31, the other end is walked around successively movable pulley 3, lower fixed pulley 25, movable pulley 3, lower fixed pulley 25, guide wheel 51, upper fixed pulley 21 and is fixedly connected with car 12 tops, forms multiplication mechanism.
Principle of work
Through the control of electric control system, under the effect of servomotor 19, ball-screw 23 produces speed-changing rotation motion, converts to and drive movable pulley 3 to do upper and lower gradually change speed linear motion through screw 24; Steel rope 13 is through movable pulley 3, and fixed pulley 29 is around combination and make steel rope 13 obtain being several times as much as the kinematic velocity of change up and down and the displacement of movable pulley 3 through the drive of movable pulley 3; Steel rope 13 through movable pulley 3, fixed pulley 29 around combination after fixed pulley 21 in pile warp, the ascending, descending campaign of car 12 generation speed change under the pulling of steel rope 13.Under the restriction of car 12 through leading boots 11, guide rail 10, do not produce and rock.Balance wheel 27 prevents that lower fixed pulley 25 from producing moment of torsion.Lead boots 11 and be provided with safety tongs, in the time that steel rope 13 ruptures, safety tongs, by locked guide rail 10, prevents that car 12 from falling, and plays security insurance effect.Balance wheel 27 is contained in compensating groove 6 movable pulley frame 5 can not be rotated around ball-screw 23, play and prevent from rotating because the contrary transmission of ball-screw 23, screw 24 makes movable pulley frame 5, thereby guarantee car 12 is realized dipping and heaving.
