Abstract
Retroreflective tape 28, 29 disposed on select positions on an elevator guide rail 13 is sensed by infrared transceivers 24, 25 disposed on an elevator car 10 to provide a signal indicative of the elevator as being at a vertical position in a hoistway designated by said retroreflective tape.
Description
The present invention relates to utilize being in of being launched to detect the position of elevator in its motor-pumped well so that the signal of expression elevator position is provided along the ray of the retroreflective tape reflection of the ad-hoc location of elevator hoistway.
Elevator hoistway extends to the lower end landing from the upper end landing.Below the landing of lower end shock absorber is arranged, it may comprise spring, oil snubber or comprise the two.Elevator safety codes requires to check the speed of elevator when elevator is reached home landing so that guarantee that the speed of elevator is reduced to rational safety speed otherwise elevator may not normally rest in landing and may collide the top of motor-pumped well or be in shock absorber bottom the motor-pumped well.In order to look at whether elevator suitably slows down, utilize switch to detect the position of elevator in motor-pumped well so that in time indicate the point that should check elevator speed, guarantee that elevator is slowly.In some cases, described switch is installed on the elevator cage and by being installed in the cam-engaged on the guide rail; In other cases, described cam is installed in the elevator cage and various switch is installed on the guide rail.In both, under any situation, utilize the end to have the pivot arm of roller to operate described switch usually, described roller and the engagement of described cam face.
Under all these situations, the cost that cam or switch are installed in the motor-pumped well is very high.Described elevator switch and cam need quite a large amount of maintenances.When roller and described cam-engaged and described contact open and closure, produce unacceptable noise.Along with the raising (for example up to 10 meters of per seconds) of elevator speed, mechanical force cause described switch must be firmer, produce bigger noise and the more frequent replacing of needs.
Purpose of the present invention comprise be provided for determining elevator position discrete in the motor-pumped well cheaply, maintenance workload little, quiet switching device.
According to the present invention, retroreflective tape is installed on the guide rail in the elevator hoistway, and the dual-purpose machine emission of infrared receiving/transmission infrared beam, the latter reflects back into described transmitter receiver from described retroreflective tape.According to the present invention, retroreflective tape can be installed in the side of guide rail and by the transceiver machine testing of outwards installing from the top of elevator cab, perhaps, retroreflective tape can be arranged on the base of guide rail and by the transceiver machine testing that is arranged on elevator cab, anyly is convenient to implement the present invention and just how does.
By means of following detailed description to the of the present invention exemplary embodiment shown in the accompanying drawing, other purpose of the present invention, feature and advantage will become clearer.
Fig. 1 is unique accompanying drawing of the present invention, is partly cut open the top plan view of the elevator cab that part extracts that the figure illustrated is according to a pair of retroeflection transmitter receiver of the present invention.
Most preferred embodiment of the present invention
With reference to described accompanying drawing, have top cover 11 and munnion 12 shown in the figure, be in the elevator cage 10 of its normal run location that is close to guide rail 13, described guide rail 13 is by the carriage (not shown), be fixed on the building in known manner.Described guide rail is a T shape, and it has: the guide rod part 15 on three surfaces 16 is arranged, and described track adjusting wheel leans against operation on the surface 16; And base portion 17.Described above is conventional art.
According to the present invention, a pair of transmitter receiver 24,25 that transmits and receives infrared- ray 26,27 is arranged on the top cover 11 by means of suitable carriage 20-22.The retroreflective tape 28,29 of described ray shoots on base that is separately positioned on guide rail 13 and guide rod.Can be being arranged on and being provided with 28 with different upright position, 29 upright position, thereby, when elevator in motor-pumped well when vertical direction moves two unique different positions of indicating elevator.On the other hand, can be being arranged on upright position identical on the guide rail 13 with 28,29, so that the dual redundant system is provided.Munnion 12 can have and is used to the hole 32 that allows ray 26 pass.Described band can be 3M Retroreflective Tape No.3870.Described transmitter receiver can be from Pepperl andFuchs, Twinsburg, and OH obtains.
The present invention can be used for determining the position of such point, checks that at this some elevator speed is so that guarantee that this speed is lower than the desired command speed of elevator safety codes when elevator is reached home landing.If desired, the present invention also can be used to carry out first slow down restriction, second slow down restriction, direction restriction and the last restriction (in the scope of rules permission).Obviously, in the scope of the resolution of described device, the present invention can be used to any purpose and detect the position of elevator in the motor-pumped well.Only need single transmitter receiver 24 or 25 to use together, if desired with corresponding retroreflective tape 28 or 29.If desired, can with single transmitter receiver detect the same section that is arranged on described guide rail (guide rod or base) more than one, but be in along its retroreflective tape of different longitudinal position longitudinally.The present invention can use with the guide rail of non-T shape.Can with two transmitter receivers, for example one be arranged on be close to another above, detect single band element.
Like this, though shown and described the present invention with regard to its exemplary embodiment,, obviously, for the professional and technical personnel, can make within the spirit and scope of the present invention above-mentioned and various other variation, ignore and add.
