Abstract

PURPOSE:To circulate a plurality of cargos in up and down passages so as to increase the transport capacity and decrease the waiting time by providing a pair of looped rails having racks, and driving an elevator by means of gears. CONSTITUTION:As a driving gear 4 is driven and rotated by a driver 2, a cargo C is guided by a guide roller guide 12 via a guide roller 7 and is raised by the driving gear 4 which meshes with a rack. When the cargo C reaches the circular portion 10a of the top portion of rails, the driver 2 is rotated clockwise by the weight of the cargo C and the cargo C is turned while being held vertical and is switched to a down-passage D. Also the cargo C is similarly switched to an up-passage U at the circular portion of the bottom portion of the rails 10.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a gear drive elevator.

[0002]

2. Description of the Related Art In a conventional elevator, a cargo is suspended in a passage by a cable, and the cable is hoisted and lowered by a winch to elevate and lower the cargo.

[0003]

Therefore, in the conventional elevator, since one cargo moves up and down in one passage,
There is a limit to the transportation capacity, and therefore the waiting time for passengers is long.

It is an object of the present invention to provide a gear drive elevator in which a cargo circulates in an up passage and a down passage for increasing transportation capacity and reducing waiting time.

[0005]

According to the present invention, a pair of drive machines provided at diagonal corners of a cargo, a drive gear fixed to an output shaft of the drive machine, and a drive gear A pair of rails provided in a loop shape in an ascending path and a descending path, each of which includes a retaining wheel connected via an arm, a rack sandwiched between the retaining wheel and the drive gear and engaged with the drive gear, and the cargo opposite each other. And a vertical guide roller guide that guides the guide roller provided on the side surface.

It is preferable that the top and bottom of the rail are arcuate.

[0007]

In the gear drive elevator constructed as described above, the cargo is guided by the guide roller guide,
It is moved up and down by the drive of a retaining wheel and a drive gear that clamp the rail. Then, in the arcuate portion of the rail top, the driver rotates relatively to the arm due to the weight of the cargo, and the cargo is swung while maintaining the vertical position, and the up passage is switched to the down passage. Further, at the circular arc portion at the bottom of the rail, the cargo is switched from the downward passage to the upward passage in the same manner as described above.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4, a plurality of cargos C (only one of which is shown in each of the drawings) are housed in the up path U and the down path D, respectively. At the corners of the diagonal line of the top surface of the main body 1 of the cargo C (the left front and right rear corners when the door d side is the front surface in the illustrated example),
The driving machines 2 and 2 are provided to face each other. The output shafts 3, 3 of the drive machines 2, 2 are arranged in parallel, and a drive gear 4 is fixedly provided at the end of each output shaft 3. One end of an arm 5 is rotatably attached to the output shaft 3, and a retaining ring 6 is rotatably provided at the other end of the arm 5. Further, a pair of upper and lower guide rollers 7, 7 are provided on the left and right side portions of the main body 1, respectively.

On the other hand, a pair of rails 10 and 10 sandwiched between the drive gear 4 and the retaining ring 6 are provided, and the rail 10 is provided with a rack 11 that meshes with the drive gear 4. These rails 10 and 10 extend upward along the ascending passage U, extend downward through the arcuate portion 10u at the top, extend downwardly along the descending passage D, and extend upward through the arcuate portion 10b at the bottom so as to circulate. That is, it is formed in a loop shape.

A pair of vertical guide roller guides 11, 11 for guiding the guide roller 7 are provided upright in the up path U and the down path D, respectively. Then, on the tops and bottoms of these guides 11, 11, there are guides that spread outward in an arc shape (the guides on the bottom are not shown).
a and 11a are provided, and adjacent guide portions 11a and 11a of the ascending passage U and the descending passage D are integrally formed. A rail cover 8 that covers the rail 10 is provided at the front of the cargo C.

Next, the operation will be described with reference to FIGS. 2, 5 and 6. When the drive gears 4, 4 are rotationally driven in the clockwise direction in FIG. 2 by the drive machines 2, 2, the cargo C is guided by the guide roller guide 12 via the guide roller 7,
It is raised by the drive gear 4 that meshes with the rack 11. When reaching the arc portion 10a at the top of the rail, the cargo C
Due to its own weight, the driving machine 2 is sequentially rotated relative to the arm 5 in the clockwise direction (90 ° at the position A), and the cargo C is swung while keeping the vertical position, and is switched to the down path D. Further, in the arcuate portion of the bottom of the rail 10,
Similarly, it is switched to the up path U.

[0013]

Since the present invention is configured as described above, it is possible to circulate a plurality of cargoes in the up passage and the down passage, increase the transportation capacity, and reduce the waiting time.

Therefore, it is possible to reduce the number of elevators installed and save the installation space.
