Abstract
A service lift comprises a outer cage, a hanging cage, a driving mechanism, a guide bracket and a safeguard; the hanging cage is arranged on the outer cage; the driving system includes a motor, a reducing mechanism, which comprises last stage outputting driving pinions; the periphery of the hanging cage is provided with enclosures; the hanging cage is also provided with sag rods; the guide bracket is provided with gear racks; the driving system is positioned on top of the hanging cage; the driving pinions of the reducing mechanism mesh with gear racks on the guide bracket; the hanging cage is also provided with frequency control system. The utility model has the advantages of that: the self weight of the lift is lightened; the lift is easy to install, unload, maintain and operate; the carrying tonnage can reach 2500 kg per cage without counterweight, and the running speed is 0 to 96 meters; the driving system has stationary torque within the range from 50 to 87 Hz.
Description
Technical field:
The utility model is a kind of construction jacking equipment, particularly relates to a kind of counterweightless frequency modulation high speed building hoist.。
Technical background:
Along with high speed development of national economy, building hoist begins bringing into play enormous function at increasing building field, especially for large-engineering, the skyscraper place, it is particularly important that the use of building hoist seems, yet, because the continuous progress of production level, in order to increase productivity, economize labor time, people are to the performance of elevator, efficient requires also more and more higher, at present, because the each side technology limitation, common building hoist is not that payload ratings is little, be exactly that specified running velocity is low, in certain scope, influenced the efficient of producing, the progress of work, for this reason, can there be a kind of nominal payload big, the construction jacking equipment that running velocity is high just becomes the transportation means that people press for, and in order to satisfy client's needs, my company has developed counterweightless frequency modulation high speed building hoist.
Summary of the invention:
The purpose of this utility model provides a kind of safe, reliable, simple in structure, high efficiency, the Applicable scope jacking equipment of constructing more widely.
Realize a kind of building hoist of the present utility model, comprise outer cage, cage, transmission device, guide rail bracket, safety device, guide rail bracket is installed on the ground, cage is installed on the guide rail bracket, guide rail bracket passes cage, cage outside on four sides, being with near cage bottom cage, periphery at the cage top is equipped with fence, and suspension rod also is installed on cage, is provided with tooth bar on guide rail bracket, driving system comprises motor, speed reduction gearing, transmission gear, driving system is installed in the top of cage, the miniature gears of speed reduction gearing and the engagement of the tooth bar of guide rail bracket also are equipped with frequency conversion speed-adjusting system on cage.Building hoist of the present utility model, employing is installed in driving system the rack and pinion drive mechanism at cage top, changed the form that large-tonnage building hoist in the past must adopt counterweight, both alleviated the own wt of building hoist, do not influence the specified load-carrying capacity and the running velocity of building hoist again, and installation, dismounting, maintenance process are all simple, easy operating.Because elevator adopts frequency conversion speed-adjusting system control, under the immovable situation of other parameters, changing its running frequency by frequency conversion speed-adjusting system makes elevator realize counterweightless, large-tonnage, high-speed cruising, make elevator realize that load carrying ability is the 2500kg/ cage under the situation of counterweight, and running velocity is 0～96 meter.
As improvement, the motor of driving system is the delta connection structure.This type elevator changes the mode that traditional construction lifter motor mainly adopts the wiring of Y type, and the mode of connection of employing △ type, make driving system in 50～87Hz scope, have constant torque, reason is as follows: the motor of standard has specific rated operation point, motor produces torque rating when the frequency rated value, and traditional motor all adopts the star-like mode of connection, its rated frequency is 50Hz, because voltage no longer increases under higher frequency, therefore, reduce at the output torque of frequency during greater than rated value, and magnetic flow reduces, and when adopting the mode of connection of △ type, electric machine frequency can be 87Hz, have only when frequency during greater than its rated frequency, its output torque just can reduce, and between 50～87Hz, the output torque of motor is constant, change the speed ratio of reductor this moment, can reach higher running velocity.
The beneficial effects of the utility model are: the building hoist own wt is lighter, installs, dismantles, safeguards simple, easy operating, and need not realize that load carrying ability is the 2500kg/ cage under the situation of counterweight, and running velocity is 0～96 meter; Driving system has constant torque in 50～87Hz scope.
Description of drawings:
Fig. 1 is a main structure chart of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of building hoist, comprise outer cage 1, cage 2, transmission device 3, guide rail bracket 4, frequency conversion speed-adjusting system 5, safety device, guide rail bracket 4 is installed on the ground, cage 2 is installed on the guide rail bracket 4, guide rail bracket 4 passes cage 2, cage 1 outside on close four sides of cage 2 bottom cages 2, being with, periphery at cage 2 tops is equipped with fence 7, driving system comprises the motor (not shown), the speed reduction gearing (not shown), speed reduction gearing comprises the drive pinion (not shown) of afterbody output, suspension rod 8 also is installed on cage 2, is provided with tooth bar 9 on guide rail bracket 4, driving system is installed in the top of cage 2, driving system is by tooth bar 9 engagements of the miniature gears and the guide rail bracket 4 of speed reduction gearing, and frequency conversion speed-adjusting system 5 is installed on the cage 2.
Its operation scheme is: the transmission device 3 of elevator is installed in cage 2 tops, when elevator moves, be installed in motor, reductor running on the transmission device 3, and the miniature gears on the reductor is meshed with tooth bar 9 on being installed in guide rail bracket 4, gear moves up and down along tooth bar 9 in the process of running, thereby drives elevator craning cage 2 operations.
Motor adopts the mode of connection of △ type, makes driving system have constant torque in 50～87Hz scope.
