Abstract
The present invention relates to a position detecting device for an elevator system driven by a double-tractive apparatus, which comprises a cabin, counterweights, a cabin balancing device or a counterweight balancing device and a position detecting device installed at the cabin balancing device or the counterweight balancing device, wherein the position detecting device is used for detecting the opposite vertical height deviation of two counterweights or the ends of two tractive line of the two counterweights. The opposite vertical height deviation of the two counterweights or the ends of the two tractive line of the two counterweights can be detected in time through the device of the present invention to cause a driving and controlling device of an elevator to be adjusted and corrected, and thereby, the elevator system driven by the double-tractive apparatus which can be normally and safely operated is ensured.
Description
Technical field
The present invention relates to a kind of elevator position detector, particularly relate to a kind of position detecting device that is applicable to two traction device drives elevator devices.
Background technology
At present, the elevator of the overwhelming majority is by a traction device drives, and corresponding balance counterweight has only one, and the car flat bed control of elevator device is to utilize the leveling device of car to realize, does not generally need to detect the position of counterweight.And the elevator device of the heavy two traction device drives of biconjugate might make two counterweights owing to the phenomenon that can not on all four factor appearance in the operational process can produce not in same vertical dimension.Therefore, if can not detect the position of counterweight well, elevator operation difficulty just may appear.The elevator device of two traction device drives of single counterweight also might make two traction fag ends on the counterbalancing device produce the vertical dimension deviation, may occur elevator operation difficulty equally.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of position detecting device that is used for two traction device drives elevator devices, it can in time detect two counterweights of the heavy system of biconjugate or two counterweight traction fag end relative position deviations of single counterweight system, make apparatus for controlling elevator correction, guarantee that elevator normally moves.
For solving the problems of the technologies described above, the position detecting device of of the present invention pair of traction device drives elevator device comprises car, counterweight, car or counterbalancing device; It also is included in car balancing device place or the position-measurement device that can carry out the angle measure of the change is installed at counterbalancing device place.
Adopt position detecting device of the present invention, by position-measurement device output certain detecting signal, according to this detection signal, can obtain the vertical dimension deviation information of elevator traction fag end in both sides on the relative movement distance of the elevator device of two traction device drives that biconjugate is heavy (time) or the counterweight elevator device of two traction device drives of single counterweight (time) in operational process between two counterweights.The control system of elevator is according to these location informations, control traction equipment is adjusted the vertical dimension deviation of traction fag end in both sides on the relative position of two counterweights or the counterweight in real time according to certain rule in the operational process of elevator, make their vertical dimension unanimities in elevator hoistways, guarantee the normal operation of two traction device drives elevators.
Description of drawings
Fig. 1 is the position detecting device structural representation of the embodiment of the invention 1;
Fig. 2 is the position detecting device structural representation of the embodiment of the invention 2.
The specific embodiment
Fig. 1 is the position detecting device structural representation of the heavy two traction device drives elevator devices of the embodiment of the invention 1 biconjugate, and it comprises position-measurement device, car balancing device, car, counterweight.Described car balancing device can be a car diversion sheave 8, and a position-measurement device 10 is installed on the turning cylinder of car diversion sheave 8, and this position-measurement device 10 can adopt absolute optical encoder.The hoistway top layer and the well pit that are positioned at the relative both sides of elevator hoistways wall also are equipped with terminal location switch 11 and the terminal end position switch 12 that is applied to counterweight separately.Terminal location switch 11 and terminal end position switch 12 offer the guarded by location signal of apparatus for controlling elevator counterweight with described position-measurement device 10.
Under desirable operation conditions, these position-measurement device 10 relative car 7 no any relative motions.Because parameter and the discreteness of traction system other parts and the influence of other improper factor of two traction equipment 1,2, cause the relative motion of position-measurement device 10 and car 7, then position-measurement device 10 is exported different digital codings, according to these codings, can offer the corresponding counterweight position feed back signal of apparatus for controlling elevator, two traction equipment 1,2 of apparatus for controlling elevator control guarantee that with certain regular motion counterweight 5 and counterweight 6 appear at same vertical dimension.If position-measurement device 10 is excessive with the relative motion degree of car 7, two traction equipment 1,2 of apparatus for controlling elevator control are only stopped.
Comparing under the serious situation, counterweight 5 has bigger position deviation in vertical direction with counterweight 6, position-measurement device 10 is excessive with the relative motion degree of car 7, position-measurement device 10 outputs one code signal by a relatively large margin, be aided with counterweight 5 or counterweight 6 again and touched an on-off signal of terminal location switch 11 back outputs, then terminal location switch 11 provides forcing of counterweight to slow down and has moved spacing position at this moment.Apparatus for controlling elevator control traction equipment 1,2 guarantees that by certain regular motion counterweight 5 and counterweight 6 appear at same vertical dimension.
Under serious situation more, position-measurement device 10 is bigger with the relative motion degree of car 7, position-measurement device 10 outputs one code signal by a larger margin, counterweight 5 or counterweight 6 have been touched terminal end position switch 12, then apparatus for controlling elevator stops according to the situation that the detects control elevator emergency of terminal end position switch 12, to guarantee the normal position of lift car 7.
Fig. 2 is the position detecting device structural representation of the two traction device drives elevator devices of the embodiment of the invention 2 single counterweights.Different is that position-measurement device 10 not only can be installed on the car diversion sheave 8 with Fig. 1 for it, and can also be installed in the counterbalancing device is (at this moment, position detecting device is 14) on the equalizing bar 15.When position-measurement device 14 relative counterweights 5 produced relative motion, apparatus for controlling elevator was in time regulated, and made the relative vertical dimension deviation of counterweight fag end 3,4 obtain revising, to guarantee the normal position of lift car 7.
The hoistway top layer and the well pit that are positioned at the elevator hoistways wall also are equipped with terminal location switch 11 and the terminal end position switch 12 that is applied to car separately.Terminal location switch 11 and terminal end position switch 12 offer the guarded by location signal of apparatus for controlling elevator car with described position-measurement device 14.
