(54) DEVICE FOR OPENING AND. CLOSING

t

The invention relates to reciprocating mechanical mechanisms driven by linear electric motors, in particular, to devices for you moving the door leaves with a linear motor.

According to the main author. Ev, No. 541766, a device for opening and closing cab doors is known, comprising a guide rail, a li-drive with an inductor and a reactive tire, and rollers of the door leaflet rollers, the inductor provided with rollers interacting with the inner surface of the tire, on the outer surface which are installed rulers interacting with the ruler, the inductor being connected to one of the carriages of the flaps, and the reactive tire connected to the carriage tl3.

The disadvantage of the known device is its inability to regulate the speed of movement of the valves of the two- ELEVATOR CABIN DOORS

Rei in the process of closing - opening in order to minimize the time of their work without. reducing the safety of passengers.

The purpose of the invention is to increase operational safety.

This barrel is achieved by the fact that the device is equipped with a fixing unit containing a spring-loaded two-arm double row mounted on the movement path of the reactive sheath with a latch on one shoulder and a figured direction on the other and an emphasis, as well as a spring-loaded rod having palees that interact with the figured one. Direction of IS l $ rest, and mounted on a carriage, with the possibility of a connector with a reactive tire, made with a groove on one of its parts, which interacts with the rod, and a retainer on the other, interacting with the latch y.

FIG. 1 shows the proposed device (with closed doors), the general view in FIG. 2 - fshssashsh node; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 2, The device for opening and closing the doors of the elevator car includes a linear drive with inductor 1 and jet bus 2, carriages I and 4 door wings, connected by a balancing device 5, which provides a uniform divergence of the doors, and roller devices 6 and 7, ensuring constant The gap between the inductor 1 and the reactive tire 2, and the movement of the carriages 3 and 4 of the door leaves in the guide bar 8. The carriage 4 is rigidly connected to the inductor 1, and the carriage 3 is equipped with a stopper 9 with a spring-loaded stem 10 with a finger 11, set The tire 2 contains a groove 13 in which the rod 10 and the retainer 14 periodically enter. At the same time, the fixing unit with the successively mounted two shoulders with the thrust 15 and the stop 16 is mounted on the way of moving the sash. from shoulders 17 and 18 pivotally connected to each other. The shoulders are mounted on the strip 19, respectively, using the axis 20 and t of the Al 21, mounted in the shaped groove 22 completed in the strip 19, In addition, the shoulder 17 is provided with a latch 23 cooperating with the latch 14 of the reactive tire 2, and the shoulder 18 contains the shaped guide , made in the form of a protrusion 2.4, interacting with the finger 11 of the rod 1O. The arm 17 is spring-loaded spring 25. The device operates as follows. When the door leaves are closed, the reactive tire 2 is stalled, since the stopper 9 of stopper 9 is in slot 13. When voltage is applied to the winding of inductor 1 in the reactive bus 2, currents whose interaction with the traveling electromagnetic field of the inductor causes movement in the direction of the inductor and reactive bus 2, and, therefore, the associated door leaves. As the door leaves are moved due to the use of the principle of relative movement, they move at a low speed. In this case, the uniform distribution of the carriages 3 and 4 of the valves is provided by a balancing device 5 74 When the reactive tire 2 approaches the stop 16, the latch 14 interacts with the latch 23 of the spring-loaded arm 17. As a result of this interaction, the arm turns on the axis 20 clockwise. However, the spring 25 immediately after the end of the engagement of the latch 14 and the latch 23 returns the arm 17 to its original position. In this case, the latch extends beyond the retainer, and the reactive tire, reaching the stop 16, stops. The door leaves begin to move at high speed, while the transfer of traction force from inductor 1 to carriage 3 occurs through a balancing device 5. At this moment, the reactive tire 2 and carriage 3, finger 11, rod 10 slides along the lower surface A of the protrusion 24 , and the rod 10 of the stopper 9 extends from the groove 13 of the jet bus. When the leaflets reach the end position, the inductor is de-energized, the carriages and, correspondingly, the leaflets associated with them, stop. To grind the casements, the doors supply power to the inductor with the change: phase alternation. At the same time, the carriages move at high speed, since the tire is split with the carriage 3 and fixed by the latch 23. When the stopper 9 reaches the reactive tire, the rod Yu enters its groove, the finger 11 slides along the upper surface B of the protrusion 24, thereby shifting the shoulder 18 tons 15 down, with the finger 21 moving in the groove 22 of the bar 19. The shoulder 18 acts on the other arm 17, which is rotated clockwise on the axis 20 and the reactive tire 2 is unlocked, And since the rod 1O of the stopper 9 is in slot 13 reactive tires, carriage 3 and 4 start the engine at low speed until the door leaves completely closed. The amount of movement of the door leaves can be adjusted at high and low speeds by moving the stop 16 and 15 sufficiently. In the device for opening and closing the doors of the elevator car, both linear AC motors (asynchronous) and linear DC motors can be used. The device makes it possible to shorten the travel time of the door leaves without at the same time reducing the safety of passengers. thereby reducing the time of the cab stand and increasing the carrying capacity of the transport system. The device can be used in other constructions of reciprocating-translational electric drives, where the described operating mode of the drive is required, for example, on the subway. The invention The device for opening and closing the elevator car according to ed. St. No. 541766, characterized in that, for the purpose of safe operation, it is provided with a fixing unit comprising successively 76 spring-loaded two shoulders mounted on the path of the reactive tire with a latch on one shoulder and a figured guide on the other and an emphasis, as well as a spring-loaded rod having a finger cooperating with a figured guide and mounted on a carriage connected with a connector with a reactive tire made with a groove on one of its parts interacting with the rod and a lock on each other ohm, interacting e latch.
