Abstract
The utility model discloses an elevator leveling signal device which is composed of a permanent magnetism induction type or photoelectric type leveling switch on the top of an elevator car and magnetic shading plates which are arranged on well channels of each layer of station. In the utility model, the work surface of one of the magnetic shading plates is provided with a plurality of opening holes. The leveling switch continuously send out pulse signals under the action of the magnetic shading plates in the process of elevator leveling for causing a control system of the elevator to judge the actual position of the running elevator car and to continuously adjust running speed according to the position of the elevator car for realizing the deceleration according to the distance principle and the accurate leveling of the elevator. The utility model is suitable for being used for elevators adopting PC control systems.
Description
Technical field
The utility model is the electrical control gear about elevator, specifically, is a kind of device that sends the Elevator landing signal.
Background technology
Lift car is desired to make landing sill in car sill and the corridor to reach conplane action and is called flat bed when stopping stop.In order to guarantee langding accuracy, need when the approaching stop of car stop, send the flat bed signal.Usually the flat bed signalling apparatus of elevator is to be provided with like this: the car top at elevator is provided with leveling switch, and the car stop position of each stop is provided with the screening magnetic sheet that can act on leveling switch in elevator hoistways.Leveling switch is the permanent magnet induction formula, makes side " recessed " font, end dress U-shaped permanent magnet, and other end dress dry-reed tube switch, dry-reed tube switch is subjected to magnet magnetization that its normally closed contact is disconnected, the open contact closure; Hiding magnetic sheet is the bar shaped sheet iron, when lift car during near certain stop, hides in the opening of magnetic sheet inserting side " recessed " font leveling switch, forms magnet short-cut path, and dry-reed tube switch is discharged, and sends the flat bed signal.
Development along with electronics industry, the leveling switch of elevator also has use photoelectric switch formula at present, its profile also is side " recessed " font, one end is provided with luminescent device, the other end is a light activated switch, and in the opening of " screening magnetic sheet " inserting side " recessed " font switch, light is blocked, make the light activated switch action, send the flat bed signal.The more rational title of screening magnetic sheet that acts on photoelectric switch should be " anti-dazzle device ", and is long because elevator industry is used the history of permanent magnet induction formula leveling switch, and people get used to screening magnetic sheet, anti-dazzle device are referred to as the screening magnetic sheet.
This type of flat bed signalling apparatus weak point is that elevator can not send operating cage position signal continuously in the flat bed course of action.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of flat bed signalling apparatus that can send car position information continuously is provided.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: adopt permanent magnet induction or photo-electric leveling switch, the screening magnetic sheet that acts on leveling switch is provided with a plurality of holes that are arranged above and below.In the Elevator landing course of action, leveling switch moves with lift car, hide magnetic sheet and act on leveling switch, whenever by a hole that hides magnetic sheet be break-make once, send an impulse singla.The control system of elevator is to the flat bed impulse singla that sends continuously record, computing, can judge car each accurate position constantly that is in operation, and constantly adjusts the running velocity of elevator by the actual position of car, stops until the accurate flat bed of elevator.
Compared with prior art, the utility model has the advantages that the flat bed signal that is sent has comprised the elevator car position information of continuous variation, help realizing " pressing distance principle slows down " and accurate flat bed of elevator.
Description of drawings
Fig. 1 is the structural representation of first embodiment of Elevator landing signalling apparatus.
Fig. 2 is the structure sketch of Fig. 1 device.
Fig. 3 is the structural representation of second embodiment of Elevator landing signalling apparatus.
Among the figure, 1. hide magnetic sheet, 2. permanent magnet induction formula leveling switch, 3. dry-reed tube switch, 4.U shape permanent magnet, 5. housing, 6. photo-electric leveling switch.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Fig. a kind, hiding magnetic sheet 1 length is 1000mm, is provided with the rectangle opening of 25 20 * 40mm, is distributed on to hide the magnetic sheet high order end, makes the screening magnetic sheet become rectangular teeth tooth bar shape.The structure of permanent magnet induction formula flat bed signalling apparatus is installed dry-reed tube switch 3 at an end of side " recessed " font housing as shown in Figure 2, other end installing U-shaped permanent magnet 4.Under the effect of U-shaped permanent magnet, the normally closed contact of dry-reed tube switch is opened, the open contact closure.When hide magnetic sheet 2 have monolithic part to insert in its opening the time, form magnet short-cut path, dry-reed tube switch recovers normally closed contact closure, the state that open contact is opened.
Permanent magnet induction formula leveling switch 2 is installed on the lift car top; Hide magnetic sheet and be installed on the cage guide of hoistway, one of every stop, the centre that hides magnetic sheet when lift car is in the accurate level position of this stop is in the opening of leveling switch, hides magnetic sheet upper end or lower end anomaly layer switch 500mm.
, hide magnetic sheet and begin to insert in the opening of leveling switch to after purpose stop 500mm at elevator cage operation, leveling switch sends impulse singla continuously under the effect that hides the magnetic sheet rectangular teeth; The electric control system of elevator to the numeration of this impulse singla, calculate the actual position of car, constantly adjust the running velocity of elevator by the retardation curve of setting, stop ladder until lock under zero-speed, accurately flat bed is stopped.
Fig. 3 is the Elevator landing signalling apparatus embodiment that adopts the photo-electric leveling switch to form.Photo-electric leveling switch 6 is side " recessed " font, and an end is a luminescent device, and the other end is a light activated switch, and when the screening magnetic sheet had monolithic part to insert in its opening, light was blocked and makes the light activated switch action send signal.Because the photo-electric leveling switch has higher responsiveness, thus hide the perforate of magnetic sheet can do narrower, with the resolution of raising car position information.Hide the long 1000mm of being of magnetic sheet in this example, be provided with the rectangle opening of 250 2 * 40mm.For avoiding hiding the distortion of magnetic sheet, the perforate left position is at the close 5mm place, the magnetic sheet left side that hides.The installation of present embodiment is identical with first embodiment with using method.
Claims (2)
1. an Elevator landing signalling apparatus is made up of with the screening magnetic sheet permanent magnet induction formula or photo-electric leveling switch, it is characterized in that described screening magnetic sheet is provided with the hole more than 2, and these holes are arranged above and below in the work area that hides magnetic sheet.
2. Elevator landing signalling apparatus according to claim 1, the hole that it is characterized in that the setting of described screening magnetic sheet is a rectangle, and the rectangular opening height is 20～100mm, and wide is 20～40mm, is arranged above and below in the work area that hides magnetic sheet; One side of rectangular opening overlaps with hiding the magnetic sheet edge, and promptly rectangular opening is an open pore, and hiding magnetic sheet becomes the rectangular teeth spline-simulating.
