Description
Technical field
The utility model belongs to elevator field, relates in particular to elevator parking system, specifically, relates to the elevator parking system based on grating measuring.
Background technology
As everyone knows, elevator, when arriving appointment stop, need to be stopped corresponding flat bed, to guarantee passenger's discrepancy safety.At present, elevator parking system is mainly by control system, is installed on the rotary encoder on towing machine, is installed on the flat bed inductor on car, and orders about these parts compositions of magnetic isolation plate of inductor action.Its concrete grammar is: when elevator will arrive appointment stop, the flat bed inductor being installed on car is triggered, and at this moment elevator enters deceleration regime, with low velocity, moves; The pulse count that algorithm conversion and control system are exported by rotary encoder, calculates current apart from level position remaining how many distances also; Then by complicated algorithm, change, obtain the pulse count of remaining how many rotary encoders, when deceleration of elevator operation, when the pulse count of rotary encoder output conforms to system, elevator just stops.
Prior art weak point is: when (1) causes magnetic isolation plate or sensor location to change due to external force factor, elevator just can not accurately judge stopped distance, causes the requirement of flat bed out of reach, and elevator need to relearn; (2) due to the mechanical tolerance on fit of elevator whole system, depend merely on the rotary encoder output pulse that is installed on towing machine and calculate distance and have indeterminacy factor, thus the potential safety hazard of bringing; (3) to algorithm conversion and control system require highly, mean that the circuit structure of this part, physical structure are very complicated, mean the stop low precision of this technology simultaneously.
Summary of the invention
For the deficiencies in the prior art part, a kind of elevator parking system based on grating measuring of the special proposition of the utility model, it can not only address the deficiencies of the prior art, and also has other many useful effects.
Elevator parking system based on grating measuring, comprise rotary encoder 1, inductor 2, magnetic isolation plate 3, car 4, tractor 8, traction rope 9, stop flat bed 10, car 4 is driven by tractor 8 through traction rope 9, rotary encoder 1 is arranged on tractor 8, inductor 2, magnetic isolation plate 3 is arranged on car 4, also comprise grating reading head 5, scale grating 6, control system 7, grating reading head 5 is arranged on car 4, scale grating 6 is arranged on to be stopped on flat bed 10, grating reading head 5 and scale grating 6 are suitable, control system 7 and rotary encoder 1, inductor 2, grating reading head 5, tractor 8 is electrically connected to.
In order better to realize technical purpose of the present utility model, above-mentioned grating reading head 5 is arranged on the top of car 4 and is positioned at and points to a side of stopping flat bed 10, and scale grating 6 is arranged on to stop on flat bed 10 and be positioned at and points to car 4 elevator door capable of being opened one sides.
Above-mentioned stop flat bed 10 refers to the floor of building jurisdiction, and each floor of this building is qualified stop flat bed, when elevator runs to this floor, if needed, accurately stops this floor, is specially the flat bed of this floor.
Principle of work of the present utility model is: when elevator will arrive appointment stop, the inductor 2 being installed on car is triggered, and at this moment elevator enters deceleration regime, with low velocity, moves; Elevator low speed also enters behind the position of scale grating 6, and grating reading head 5 starts read out circuit car 4 support identity distances from the diff-H of flat bed; When the signal of grating reading head 5 and scale grating 6 flat bed points overlaps, elevator is out of service, has really realized the closed loop control of elevator parking, has improved the precision of elevator parking flat bed.
The beneficial effects of the utility model are: (1) stop precision is high.By the adaptation of grating reading head 5 and scale grating 6, and the cooperation of other mechanism such as control system, without complex calculations, can reach and cause technical purpose of the present utility model, realize accurately flat bed reliably and stop, improved the safety factor of elevator; (2) simple and fast, convenient and reasonable.Single member of the present utility model is very easily developed or buys, and energy Fast Installation, rationally utilizes space, easily reaches and causes technical purpose of the present utility model.
Due to above-mentioned beneficial effect, the utility model is widely used in all types elevator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, elevator parking system based on grating measuring, comprise rotary encoder 1, inductor 2, magnetic isolation plate 3, car 4, grating reading head 5, scale grating 6, control system 7, tractor 8, traction rope 9, stop flat bed 10, car 4 is driven by tractor 8 through traction rope 9, rotary encoder 1 is arranged on tractor 8, inductor 2, magnetic isolation plate 3 is arranged on car 4, grating reading head 5, scale grating 6, control system 7, grating reading head 5 is arranged on the top of car 4 and is positioned at and points to a side of stopping flat bed 10, scale grating 6 is arranged on to stop on flat bed 10 and be positioned at and points to car 4 elevator door capable of being opened one sides, grating reading head 5 and scale grating 6 are suitable, not only geographically but also at signal carry in reception and all act in concert with each other, control system 7 and rotary encoder 1, inductor 2, grating reading head 5, tractor 8 is electrically connected to, for controlling the operation of these parts or action etc.
Like this, when elevator will arrive appointment stop, the inductor 2 being installed on car is triggered, and at this moment elevator enters deceleration regime, with low velocity, moves; Elevator low speed also enters behind the position of scale grating 6, and grating reading head 5 starts read out circuit car 4 support identity distances from the diff-H of flat bed; When the signal of grating reading head 5 and scale grating 6 flat bed points overlaps, elevator is out of service, has really realized the closed loop control of elevator parking, has improved the precision of elevator parking flat bed.
