Description

  The present invention relates to a self-propelled elevator that moves vertically and horizontally on a wall surface of a hoistway.

As a conventional technique, one way to increase the elevator operating efficiency and reduce the waiting time is to move the hoistway not only in the vertical direction but also in the horizontal direction without the need for the rope and hydraulic plunger shown in Patent Document 1. A self-propelled elevator with a linear motor is considered.
However, in order to respond flexibly to customers with this method, magnets must be stuck around the vertical shaft of the hoistway, and wireless control also has the risk of malfunctioning when using ordinary electromagnetic waves, An electromagnetic shield is also required for the elevator car.

Further, according to the sixth aspect of the invention, it is possible to move by moving the elevator car that is vertically, diagonally or laterally.

One embodiment of the present invention is shown in FIGS.
The self-propelled elevator main body 1 is a self-propelled elevator having a drive device on the elevator car side, and includes an elevator car part 10, a coupling part 20, and a suction part 30, and is provided on the back of the elevator car facing the hall entrance. The elevator car 10 is supported via the coupling part 20 by the suction part 30 being vacuum-sucked on the hoistway wall surface WB.

  The suction unit 30 includes a suction plate 31 that faces the suction surface of the hoistway wall WB with a slight gap therebetween, and a suction machine 32 that is mounted on the suction plate 31 and reduces the atmospheric pressure in the slight gap. A drive wheel 33 that creates the above-mentioned slight gap in the left and right pair toward the hoistway wall WB, a photosensor 34 provided at the front and rear ends of the suction plate 31 in the traveling direction of the drive wheel 33, and a suction plate The rechargeable battery 36 includes a skirt 35 made of a flexible sheet material, which is attached along the left and right side surfaces 31 in the traveling direction and improves the airtightness in the above-described air pressure-reduced gap.

  The coupling portion 20 includes a coupling plate 21 that is rotatably coupled to the suction plate 31 by the coupling portion 40, a coupling floor 22 that is joined to the coupling plate 21 at a right angle to support the elevator car 10, and the coupling plate 21. An elastic body 23 that absorbs vibration while pressing the elevator car portion 10 and the suction portion 30 against the hoistway wall surface WF and the hoistway wall surface WB, respectively, and the elevator car portion 10 and the suction portion 30 due to vibration absorption of the elastic body 23. Two rails 24 installed on the coupling floor 22, a stopper 25 protruding to the hoistway wall surface WB by the hydraulic mechanism when the suction portion 30 is stopped, and the stopper 25 It comprises a stopper shoe 26 attached to the tip.

  The elevator car unit 10 is an auxiliary car body 11 and an auxiliary car that rotates freely in four directions by the elevator car body 11 being pressed against the hoistway wall surface WF via the upper arm 18 and the lower arm 19 by the elevator car body 11. It is comprised from the wheel 12 and the rail wheel 13 which accept | permits the above-mentioned relative movement on the rail 24. FIG.

In addition, the above-mentioned drive wheel 33 considers that the suction plate 31 is rotated by rotating the left and right wheels reversely with each other in consideration of the stability of the suction plate 31 and the upper and lower intervals do not exceed the left and right intervals. The stopper 25 is installed in the diagonal direction symmetrical to it.
Moreover, in the connection part 40 in one Embodiment shown here, it sets so that the free rotation of the coupling plate 21 and the adsorption | suction board 31 may become every 90 degree | times.

  In addition, the suction surface of the suction plate 31 is not straight and has a gentle slope toward the suction port of the suction machine 32 so that the suction efficiency is good, and the suction machine 32 has a silencer to reduce noise. It has been incorporated.

  The driving wheel 33, the auxiliary wheel 12 and the stopper shoe 26 are made of a material having excellent cushioning and frictional force such as rubber, so that it can be operated when the power is turned off when stopping at a boarding / exiting floor or during a power failure. The brake device set to 1 fixes the wheels of the drive wheel 33 and the auxiliary wheel 12 and presses the stopper shoe 26 of the stopper 25 against the hoistway wall surface WB.

Now, when the self-propelled elevator main body 1 releases the brake device and starts moving away from the floor where it has been stopped, the suction plate 31 is hoisted by the protrusion of the drive wheel 33 while being sucked by the suction machine 32. A gap formed between the wall surface WB and the wall surface WB is surrounded by a skirt 35 along the traveling direction, and the space is reduced from the atmospheric pressure to adsorb only the drive wheels 33 in contact with the hoistway wall surface WB.
On the other hand, the auxiliary wheel 12 is pressed by the elastic body 23 together with the elevator car body 11 and adhered to the hoistway wall surface WF. At this time, the elevator car main body 11 remains without falling between the hoistway wall surfaces WF and WB.

Here, if the motor 330 is driven and the driving wheel 33 is rotated in the same direction, the self-propelled elevator main body 1 can move upward or downward. Further, if the driving wheels 33 are rotated in opposite directions, only the suction plate 31 is rotated 90 degrees. If the driving wheels 33 are rotated in the same direction thereafter, the top and bottom of the elevator car body 11 are left in the horizontal direction. Can be moved to.
On the other hand, the white line L corresponding to the optical sensor 34 is drawn vertically and horizontally on the hoistway wall WB, and the movement of the self-propelled elevator main body 1 can be controlled by using it as a guide.

  In addition, by performing the release of the brake device and the rotation direction of the drive wheels 33 and the control of the sensor traveling wirelessly, for example, a hoistway where a plurality of elevators run in parallel is made a common laterally movable space, When the spare elevator car is placed on the lowest floor, middle floor, and top floor and charging is frequently concentrated on a specific floor, such as when lunch is frequently concentrated on a specific floor, the elevator car on the side and top and bottom can be used according to the hall call on each floor. The number of elevators and their routes are controlled by arriving at and leaving the spare elevator car, and the use status of elevators without having to rely on probabilistic management operation or laying out magnetic fields. Can deal with ad hoc changes.

  In addition, since vertical and horizontal switching and operation can be performed simply by changing the direction of rotation of the drive wheels 33, if the hoistway can be shared, the doorway to the doorway instead of the corridor in a condominium etc. is adapted to safety and convenience. You can move on your favorite route, and if you have improved collision avoidance control and retreat routes, you can move across the apartments like a car.

In the case of this embodiment, the travel route is controlled by the optical sensor 34 and the white line L, but the present invention is not limited to this combination.
In addition, the traveling direction of the suction plate 31 is limited to the vertical direction and the horizontal direction so that the auxiliary wheel 12 can avoid the door or the sill on the elevator hall side, but the auxiliary wheel 12 may not be required. For example, the suction plate 31 may be freely rotated and fixed by the connecting portion 40 and travel in any direction.

  Further, in the case of this embodiment, a suspension is not attached to the auxiliary wheel 12 side in order to maintain the clearance between the hall side door and the car side door. The elastic body 23 is not limited to the coil spring, and a damper function may be added.

It is an installation state figure showing one embodiment of the present invention. It is an AA arrow line view which sees the A direction of FIG. It is a BB arrow line view which looks at the B direction of FIG. FIG. 3 is a detailed CC view as seen in the direction C of FIG. 2.
