〔Example〕

Hereinafter, the present invention will be explained in detail based on drawings showing embodiments.

In FIGS. 1 and 2, reference numeral 1 denotes a composite conveyance device constructed by connecting wheel conveyor means 2, 2 on both side U-turn sections and chain conveyor means 3 between both side turn sections, and the wheel conveyor means 2,
2 and the chain conveyor means 3 respectively have a flat area 4,
5 and the inclined part 6. 7 is the flat area 4,
This is a platform for boarding and alighting located halfway between the wheel conveyor means 2 and 2 of No. 5.

The wheel conveyor means 2 is composed of a plurality of drive wheels 8 in a row that are rotationally driven by an electric motor (not shown), and transmits the rotational force of these wheels 8 to a vehicle 9 through frictional contact to drive the vehicle 9. let Reference numerals 10, 10 are two guide rails laid over the entire length of the device 1 to guide the vehicle 9, and are arranged parallel to each other with a predetermined width on both sides of the wheels 8.

The chain conveyor means 3 consists of two endless chains 12, 12 driven by an electric motor 11 as a driving source, as shown in FIG. The drive chain 12 is located inside the guide rails 10, 10, has both ends rotatably supported by a driven wheel 13 and a driving wheel 14, and is rotatably supported between them by a plurality of support wheels (not shown). A driving wheel 14 driven and rotated by a motor 11 is driven in the traveling direction X, thereby causing the vehicles 9 engaged with the chain 12 to be hoisted up or pulled down.

Further, one of the endless chains 12, 12 is a lifting drive chain 12A, 12A, and the other is a pulling drive chain 12B, 12B.

That is, this rotation transmission mechanism 20 includes three bevel gears 17, 18,
19, and an idler wheel 16 on the drive chain 12A side.
A bevel gear 17 is attached to a shaft 39 connected to the
A bevel gear 18 is attached to a shaft 40 connected to the idler wheel 16 on the drive chain 12B side. The bevel gear 19 meshes with the bevel gears 17 and 18. Therefore, when shaft 39 rotates clockwise, shaft 40 rotates counterclockwise. In addition, bevel gear 1
7 and 18 are the same, and both floating chains 1
5 and 15 are interlocked at the same speed, and as shown in FIG. 6, the pitch A of the floating chain 15 is the same as the pitch B of the drive chain 12, and the floating chain 15 has a constant positional relationship with respect to the drive chain 12. It is becoming like this.
