Compared with prior art, the utility model is rotated power loss back nut by transfer wheel, the structure of the gentle bar of rack gear
Kinetic energy be transferred to gas bar, be converted into the potential energy consumption of gas, until gas bar moves on to extreme position, nut is thoroughly locked, reached
To braking effect.Under normal circumstances, lift bracket is located at below nut, and transfer wheel thereon is not contacted with nut.In power loss
In the case where, electromagnet loses suction, and lift bracket drives transfer wheel opposing nut uplink and is in contact with it, and realizes above-mentioned braking
Effect.By the above content it is found that the structure of gas bar energy consumption keeps the down speeding procedure of the utility model steady, impact will not be generated.
Further, the utility model connects motor and nut by belt, on the one hand can reduce the vibration of transmission,
On the other hand noise can be reduced.
Further, the utility model acts lift bracket by spring stop structure, and this structure is simply easy to
Manufacture.
Further, for the utility model using electromagnet as power loss trigger device, simple and stable structure is good, accidentally touches
Hair rate is low.
Further, the exhaust valve of gas bar can timely pressure release, prevent from damaging.
To sum up, the utility model has the function of that power loss braking, safety are more preferable.Meanwhile the utility model also has system
Dynamic process is gentle, impacts small feature.In addition, the utility model also has the characteristics that structure is simple, false triggering rate is low.

Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to
According to.
Embodiment: the driving structure of elevator without counterweight, including the screw rod 10 being vertically arranged, car frame is equipped with and screw rod 10
The nut 20 of cooperation is additionally provided with the motor 30 being connected with nut 20 on car frame；It is additionally provided on the screw rod 10 positioned at nut
The transfer wheel 40 of 20 lower sections, the lower end of nut 20 are equipped with clutch fixture block 21, and the upper end of transfer wheel 40 is equipped with matches with clutch fixture block 21
The clutch hole 41 of conjunction；The side wall of the transfer wheel 40 is equipped with tooth 42, and car frame is equipped with the rack gear 50 cooperated with tooth 42, rack gear 50
It is connected with the gas bar 51 being fixed on car frame；The transfer wheel 40 is arranged on lift bracket 60, lift bracket 60 and sedan-chair
Compartment frame is connected through flexible drive device 70 with power loss trigger device 80.
Clutch fixture block 21 and clutch hole 41 are the passes engaged and be detached from the relative height differential of nut 20 according to transfer wheel 40
System.Also, when clutch fixture block 21 is engaged with clutch hole 41, the tooth 42 of 40 side wall of transfer wheel is also engaged with rack gear simultaneously.
The motor 30 is connected through belt with nut 20.
The flexible drive device 70 include cover on the spring 71 and lift bracket 60 on lift bracket 60 with spring
The baffle 72 of 71 cooperations.
The power loss trigger device 80 includes the electromagnet 81 being connected with elevator major loop, and is located at lift bracket 60
The upper armature 82 matched with electromagnet 81.
The gas bar 51 is equipped with exhaust valve.
Working principle:
The structure of the utility model is as depicted in figs. 1 and 2 (being not drawn into the figures such as lubrication system), fixed on vertical car frame
There are two pieces of parallel clamping plates, there is the output end and nut 20 of motor 30, the percutaneous band connection of the two, between nut 20 and clamping plate between clamping plate
It is connected through thrust bearing.There is transfer wheel 40 in the underface of nut 20, and transfer wheel 40 is located on lift bracket 60, and lift bracket 60 is living
It is dynamic to be fixed on car frame.Screw rod 10 passes through clamping plate, nut 20, transfer wheel 40 and lift bracket 60, wherein only nut 20 and spiral shell
Bar 10 cooperates.
In normal state, motor 30 drives nut 20 to rotate through belt, and car frame is through screw rod 10 and nut 20 as a result,
Cooperation can move up and down.The armature 82 on lift bracket 60 is sucked in electromagnet 81 at this time, in conjunction with lift bracket 60 and transmitting
Wheel 40 self weight, so that lift bracket 60 is in lower limit position, spring 71 is compressed, transfer wheel 40 not with nut 20 and rack gear 50
Contact.
Under complete power failure state, i.e., the power supply of no alternating current and battery, electromagnet 81 loses suction at this time, in spring
Under 71 effects, lift bracket 60 drives transfer wheel 40 to rise.Transfer wheel 40 is contacted with nut 20 and rack gear 50, through clutch fixture block 21
With the cooperation in clutch hole 41, nut 20 drive transfer wheel 40 rotate, then transfer wheel 40 with carry-over bar 50 rotate, gas bar 51 by
Pressure, forms reversed resistance.Until 51 row of gas bar keeps transfer wheel 40 stuck, nut 20 no longer rotates, and forms system to extreme position
It is dynamic.At this point, due to the pressure at 50 occlusion of tooth 42 and rack gear, transfer wheel 40 be will not fall off.
