Abstract
Driving and traction device of counterbalance comprises inside counterweight iron(8) and outside counterweight iron(10), the character is to fix the motor(5), locating piece(9), guide wheel(11), rope end plate(12), roller wheel(12), electrical control elements(14) and reducer(15) into counterweight frame(6) and impaction frame(7) for one body, it can be used for driving and traction of lift car and for counterweight of counterbalance. one end of wire rope is connected with top of lift car(1) and the other end of wire rope is through pulley(2) and(3) connected on rope end plate(8) of driving and traction device(4), thus the motor(5), inside counterbalance iron(8), locating piece(9), outside counterbalance iron(10), guide wheel(11), rope end plate(12), roller wheel(12), electric control elements(14) and reducer(15) are assembled in counterweight frame(6) and impaction frame(7) to form the driving traction device of counterweight(4). The device adopting small power asynchronous motor(13) through turbine worm gear reducer(9) to drive roller wheel(8) on counterbalance and control the lifting and falling of lift car by frictional force produced by roller wheel and guiding rail surface. The utility model is only need small starting current and lower energy consumption, need not lubrication oil to reach the purposes of environmental protection, energy conservation, eliminating fire hazard and simplifying architectural design. Compared with the 2:1 traction ratio system, the 2:1 traction ratio system is more save wire rope and reduces wear and tear of wire rope. In addition, the cost is decreased by adopting asynchronous motor.
Description
Affiliated technical field
The utility model relates to machine-roomless lift, drives drag device in particular for the machine-roomless lift counterweight.
Background technology
At present, machine-roomless lift main flow type of drive adopts permanent magnetic synchronous traction machine to drive, and its type of drive is made up of traction sheave A, motor C, car B, counterweight D four major parts as shown in Figure 1.Car be connected to reusing steel rope, be wound on the traction sheave, drive this traction sheave, the friction force that relies on steel rope and traction sheave surface to produce makes the car lifting, towing machine generally is mounted on the rail brackets or is installed on the pit.Be subjected to the restriction of the oad of towing machine, still taken the segment space of hoistway, and also person of modern times's meaning not of noise reduction and anti seismic efficiency.Undoubtedly, there is certain difficulty in this aspect value of service that improves no machine room.
The utility model content
In order to overcome the restriction of the oad that is subjected to towing machine that existing machine-roomless lift main flow type of drive exists, take the also problem of person of modern times's meaning not of the segment space of hoistway and noise and anti seismic efficiency, special with motor, inside and outside counterweight iron locating piece, electric controling element, retarder etc., be installed in the counterweight frame and compress and form one in the frame, both be used for the driving traction of car, be used as the part weight of counterweight again.
The technical scheme that its technical matters that solves the utility model adopts is: the counterweight in the elevator drives drag device, be that retarder fixedly is assemblied in the counterweight frame and compresses in the frame, counterweight frame and compress frame and be fixed together respectively in twos by the locating piece two ends, motor is fixed on the retarder by motor shaft is unsettled, axle on the retarder connects with roller, both be used for the driving traction of car, as the part weight of counterweight, the friction force that roller on the dependence counterweight and guide rail surface produce makes the car lifting again.
The beneficial effects of the utility model are, can very ingeniously utilize limited hoistway space, all elevator components of reasonable Arrangement, be that main frame and counterweight unite two into one, do not take any space of hoistway, also be more convenient for keeping in repair, and only need very little starting current to reach lower energy consumption, need not lubricating oil, improved the environmental protection characteristic of building greatly, 1: 1 traction ratio system as shown in Figure 2, more save steel rope and reduce the wearing and tearing of steel rope than 2: 1 traction ratio systems such as Fig. 1, select the traction steel-cable of diameter 8 ~ 10mm for use, thereby reduce the rope sheave diameter, reach purpose simple and compact for structure.Because machine-roomless lift is saved and be need not to be provided with machine room, also need not to amplify, thereby can simplify architectural design, beautifies architectural image, save building cost.Especially use asynchronous motor, efficient, energy-conservation, cost is low, has also just improved the value of service of no machine room.

The specific embodiment
The utility model specific embodiment (see Fig. 2, see Fig. 3, see Fig. 4), it comprises motor (5), counterweight frame (6), compresses frame (7), interior counterweight iron (8), locating piece (9), outer counterweight iron (10), track adjusting wheel (11), rope hitch plate (12), roller (12), electric controling element (14), retarder (15) etc.Be characterized in the counterweight in the elevator is driven drag device, be 4 retarders fixedly are assemblied in counterweight frame (6) and compress in the frame (7), counterweight frame (6) and compress frame (7) and be fixed together respectively in twos by 8 locating piece two ends, 4 motors (5) are fixed on the corresponding retarder by motor shaft is unsettled respectively, and the axle on 4 retarders (15) connects with corresponding rolling wheel (13).Both be used for the driving traction of car (1), be used as the part weight of counterweight again, steel rope one end connects car (1) top, the steel rope other end is by pulley (2), (3) be connected in counterweight and drive on the rope hitch plate (8) of drag device (4), the friction force that roller (13) (seeing Fig. 3, Fig. 4) on the dependence counterweight driving drag device (4) and guide rail surface produce makes the counterweight lifting.Counterweight links to each other with car by steel rope, moves up and down thereby drive car.
Counterweight frame (6) and compress two motors (5) have been installed on the frame (7) wherein, by locating piece (9) assembling two motors (5) and a plurality of in counterweight iron block (8), outer counterweight iron block (10), in the outside of counterweight frame (6) 4 rollers (13) have been installed, through transmission shaft driving rolls (13) rotation of retarder (15); Make (4) along the directed operation of guide rail by 4 track adjusting wheels (11).
The counterweight type of drive: car be connected by pulley to reusing steel rope, drive the roller on the counterweight, the friction force that relies on roller to produce on guide rail makes the counterweight lifting, counterweight links to each other with car by steel rope, thus the driving car moves up and down.
