Abstract
The utility model provides an automatic floor-levelling apparatus for an elevator at power failure, which is mainly composed of a main motor, an auxiliary motor, an accumulator, a retarding mechanism, etc., wherein, the retarding mechanism is connected with the auxiliary motor by a cycloid pinwheel speed reducer through a shaft coupling, and the other end of the cycloidal pinwheel speed reducer is connected to the main motor through a friction clutch. When electricity fails, the auxiliary motor is connected to a shaft of the main motor through the cycloidal pinwheel speed reducer and the friction clutch, and drags a traction machine so as to level the elevator. The automatic floor-levelling apparatus has the advantages of practicality, reliability, economy, generalization, etc.
Description
The utility model relates to a kind of elevator power failure automatic floor approaching mechanism, is specially adapted to the mechanical reduction transmission, drags and the elevator power failure automatic floor approaching mechanism of partly forming such as automatically controlled.
Have a power failure suddenly when elevator at present, and people or goods are trapped in the elevator, bring great inconvenience for people or freight lifting, adopt general fashion that people or goods are separated elevator cab and can produce bigger danger.In recent years, people are at the device of development elevator power failure automatic leveling arrival.In some elevator of introducing, useful all electronic control and the elevator power failure leveling device that drags.It is that 220 volts of alternating current are combined into 380 volts of three-phases that this device adopts 72 overhead accumulator dc inversions, and power supply machine drags and the control system electricity consumption, and this is the extremely complicated system of a cover, costs an arm and a leg, and maintenance technique requires high.The domestic people of having has set up the flat bed mechanism that starts deceleration when having a power failure in the main driving axle system of elevator traction machine, solved the difficulty that elevator has a power failure and causes with easy measure.But the cover that this device increases starts deceleration flat bed mechanism to be made of helper motor, storage battery and reduction gear device, causes floor area bigger, makes the repacking environment that certain difficulty be arranged.
The purpose of this utility model is to provide a kind of electromechanical integration, practical, reliable, economical, unitized elevator power failure automatic floor approaching mechanism.
The utility model is made up of main motor, helper motor, storage battery, speed reduction gearing.Helper motor links together by coupler and a cycloidal planetary gear speed reducer, realizes motor deceleration.The cycloid pin reductor other end is connected with main motor by friction clutch again, realizes separating--engage.When civil power just often, elevator traction machine drags elevator by main motor and normally moves, and charges a battery simultaneously.And helper motor, cycloidal planetary gear speed reducer are thrown off main motor by the effect of friction clutch.When elevator has a power failure owing to contingent, connecting auxiliary circuit by friction clutch, is that helper motor send electricity by storage battery, makes helper motor pass through cycloidal planetary gear speed reducer, friction clutch connection main motor shaft, drive towing machine, make elevator cab can continue to drive to close doorway, the Room.
Description of drawings of the present utility model is as follows:
Fig. 1 is the connection diagram of the whole dragging system of the utility model.
Fig. 2 is the connection diagram of the utility model ancillary system.
Fig. 3 is the structural representation of mechanical control friction clutch.
Below in conjunction with accompanying drawing the utility model is described in further detail: as shown in Figure 1, helper motor 1 is connected with cycloidal planetary gear speed reducer 3 by coupler 2, and cycloidal planetary gear speed reducer 3 separates by a friction clutch 6--engage main motor 7.Main motor 7 drags towing machine 9, and a band-type brake 8 is arranged between main motor 7 and towing machine 9.When the elevator normal operation, friction clutch 6 is in disengaged condition, makes helper motor 1 throw off main motor 7.Main motor 7 drags towing machine 9, and elevator cab is normally moved, and at this moment band-type brake device 8 is switched on and is in attracting state, and band-type brake unclamps.When mains failure, the ancillary apparatus system cuts off main motor 7 current supply circuits, and storage battery send electricity by inversion system to helper motor 1, magnetic clutch 6, band-type brake 8 simultaneously, and band-type brake 8 unclamps, magnetic clutch 6 adhesives, helper motor 1 drags towing machine 9 by main motor 7 and drives Elevator landing.Among Fig. 2, helper motor 1 drives blade 5 and rotates by coupler 2, cycloidal planetary gear speed reducer 3, and when blade 5 passed through dry-reed tube 11, dry-reed tube 11 sent signal, and checking system obtains the incoming signal of " 1 ".Meanwhile, magnetic clutch 6 drives blade 4 and rotates, and when blade 4 passed through near switch 10, checking system also obtained the incoming signal of " 1 ".Meter " 0 " when checking system obtains the incoming signal of two " 1 " simultaneously, no asynchronous phenomenon between expression elevator cab and the helper motor 1 is in synchronous regime.If checking system obtains one " 1 " and one " 0 " then meter " 1 " has slide relative between expression elevator cab and the helper motor 1.When No. 4 meters " 1 " occurring, mean that the principal and subordinate moves one week of part slide relative, this moment, control system made 8 outages of elevator band-type brake, band-type brake 8 lockings, and elevator is out of service, to guarantee safety.Fig. 3 is expressed as the mechanical control friction clutch, and a micro-motor 15 is handled friction lining 12 by gear 14, tooth bar 16 and piston crank mechanism 13, to reach separately joint action of friction lining 12, this power-transfer clutch does not impact in conjunction with steadily, and increase friction lining number can increase transfer torque.Although this mechanism complexity is applicable to the heavy amount elevator of transmission greater than the big dynamic torque of 45kgfm.
The utility model compared with prior art has the advantages such as practicality, reliable, economy, generalization.
