Abstract

The invention discloses an external rotor rolling elevator, comprising: cage, lifting device connecting to cage and control circuit driving elevator. The lifting device comprises duct with a built-in outer rotor rolling positioning disk. The duct has a dynamic lead-out groove along the axial direction. In the duct is an inner screw thread supporting the external rotor rolling positional disk for the helical motion. The external rotor rolling positional disk is composed of external rotor electric machine, cage arm fixed on the internal stator, girdle fixed to the cage and surrounding the internal-spiral rolling duct. The external rotor of the external rotor electric machine is produced into helical disk with helical wire to rotary-match the external rotor and internal-spiral rolling duct. The invention is suitable for producing different lifting devices.

Description

Outer rotor rolling lifter

Technical field:

The present invention relates to a kind of lifter, especially a kind of outer rotor rolling lifter.

Background technology:

German patent application DE 19931360.1, the day for announcing is on March 2nd, 2000, title is: disclose in " a kind of Spiral type escalator ": lifting mechanism comprises conduit, and described conduit in axial direction has power and derives groove, has the negative thread of screw motion in conduit.The screw rod that the elevator of this structure still adopts conventional driven by motor and negative thread to match drives elevator motion by screw rod up-and-down movement in conduit, the complex structure of this mode, and kinetic friction force is big, and save oneself during power failure operation and maintenance are all inconvenient.

Summary of the invention

The present invention has overcome the shortcoming of prior art, provides a kind of power consumption low, simple in structure, but installs and maintenance is convenient and the outer rotor rolling lifter of safety self-saving when having a power failure.

Outer rotor rolling lifter of the present invention, comprise car, the control circuit of lifting mechanism that is connected with car and the action of driving lifting mechanism, lifting mechanism comprises the conduit that is built-in with outer rotor rolling positioning disk, described conduit in axial direction has power and derives groove, in conduit, have negative thread for outer rotor rolling positioning disk screw motion, described outer rotor rolling positioning disk is by external rotor electric machine, the car that is fixed on the internal stator is hung arm, and embrace ring that encircle inside spin rolling conduit affixed with car formed, the outer rotor of external rotor electric machine manufactures the helical disk of helix line, and outer rotor and inside spin rolling guide pipe are screwed.

Have at least 3 rolling track adjusting wheels to be installed on respectively in the groove of external threaded surface of outer rotor rolling positioning disk, and slightly exceed external threaded surface, uniform around the axial line of outer rotor rolling positioning disk, with the negative thread contact matching of inside spin rolling conduit.

Two ends at the outer rolling positioning disk have the installation brake disc respectively.

The lifting mechanism that drives the car action has two.

The lifting mechanism that drives the car action has three.

Outer rotor rolling lifter of the present invention is owing to adopt above-mentioned technical scheme, car is connected with lifting mechanism, be that propulsion source is very near from cab, when having a power failure, the people need not leave cab, be installed in the brake disc at outer rolling positioning disk two ends with regard to may command, brake is unclamped, allow the outer rolling positioning disk slide naturally downwards, when arriving one deck, allow brake disc stop tightly again, open gate, the passenger of cab the inside just can safe escape; The rolling track adjusting wheel is walked having on the raceway of inside spin, the frictional force that makes outer rotor and inside spin rolling guide pipe screw rotation is the rolling frictional force, has reduced energy consumption and noise, and the rolling track adjusting wheel is being forgiven by inside spin rolling conduit, never drop-off has improved safety; Because car is connected with lifting mechanism, and is easy for installation; Maintenance only needs the structure of periodic inspection rolling track adjusting wheel and loss situation just can; Since simple in structure, manufacturing cost reduced.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail:

Fig. 1, outer rotor rolling lifter of the present invention shown in Fig. 2, car 6, the control circuit of lifting mechanism that is connected with car 6 and the action of driving lifting mechanism, lifting mechanism comprises the conduit 5 that is built-in with outer rotor rolling positioning disk 4, described conduit 5 in axial direction has power and derives groove 51, in conduit, have negative thread for outer rotor rolling positioning disk 4 screw motions, described outer rotor rolling positioning disk 4 is by external rotor electric machine 1, the car that is fixed on the internal stator 12 is hung arm 3, and embrace ring 8 that encircle inside spin rolling conduit 5 affixed with car 6 formed, the outer rotor of external rotor electric machine 1 manufactures the helical disk 111 of helix line, outer rotor and inside spin rolling guide pipe 5 are screwed, when external rotor electric machine 1 energized, controlled drive car is hung arm 3 and is embraced ring 8 drive cars 6 and moves up and down, embrace ring 8 and encircle inside spin rolling conduit 5, carry the load of a part of car 6 along with car extension arm 3 slides up and down.

By Fig. 3 and Fig. 4 as can be known, there are 4 rolling track adjusting wheels 112 to be installed on respectively in the groove 41 of external threaded surface of outer rotor rolling positioning disk 4, and slightly exceed external threaded surface, axial line around outer rotor rolling positioning disk 4 is uniform, negative thread contact matching with inside spin rolling conduit, rolling track adjusting wheel 112 comprises the dead axle that bearing is housed and is enclosed within the runner that is drum type on the bearing, the gravity that makes car 6 be applied to outer rotor rolling positioning disk 4 is distributed to each rolling track adjusting wheel 112, friction between the negative thread of rolling track adjusting wheel 112 and conduit 5 belongs to friction of rolling, make rolling track adjusting wheel 112 resistance of motion on the raceway of negative thread little, and rolling track adjusting wheel 112 is being forgiven by inside spin rolling conduit 5, never drop-off, no matter the bearing failure in some rolling track adjusting wheel or the rolling track adjusting wheel or lose even whole elevator still can stop at certain height safely and can not fall, its safety performance improves greatly; Two ends at outer rolling positioning disk 4 are separately installed with brake disc.Brake disc is in braking state under the normality.When energising, brake disc unclamps, and along with the positive reversal connection of electrode, outer rotor rolling positioning disk 4 rotatings thereupon of external rotor electric machine 1 screw on, screw off in inside spin rolling conduit 5, and when having a power failure, brake disc recovers braking state.

When unexpected generation power outage, the people need not leave cab, can manually control the brake disc that is installed in outer rolling positioning disk two ends, brake is unclamped, allow the outer rolling positioning disk slide naturally downwards, allow brake disc stop tightly again when arriving one deck, open gate, the passenger of cab the inside just can safe escape.

The inside spin conduit that rolls is made length more than one meter or one meter, utilize concave-convex-piece method location, fix with known method, be fixed on prop 10 according to the height of building on the hoistway of building or in order not take effective usable floor area of building, be installed on the exterior wall of built-in fitting, the manufacturing of high rise elevator is simplified, and cost reduces.

As shown in Figure 4, the lifting mechanism as propulsion source among the present invention has two, and as shown in Figure 5, lifting mechanism has three, and such distribution can make outer rotor rolling positioning disk 4 sizes be diminished, and the power of lifting mechanism more strengthens more steady.
