[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive device for a steep slope of a transport vehicle.

[0002]

2. Description of the Related Art An Apt-type transport vehicle has been known as a steep transport vehicle. However, it is not used for general work. In this transport vehicle, a pinion on the transport vehicle side is engaged with a rack laid along rails, and the pin-on is driven to rotate by a drive motor via a speed reducer.

[0003]

In the conventional apt-type carrier, the processing and mounting of the rack and the pinion require a high level of technology and are expensive. In addition, there is a problem that it cannot be applied to a curved road due to the meshing relationship between the rack and the pinion. Furthermore, an escape prevention mechanism in a downhill part is required.

In a fruit garden or the like, a single track provided with rack teeth is supported on the ground by a support, and a driving sprocket and a driven sprocket are provided on a carrier, and a chain wound around the sprocket is used as a single track rack tooth. A single track carrier is used in which a single track is engaged with the upper roller and the lower roller so that the single track is interposed between the upper roller and the lower roller so that the transport vehicle travels (for example, Japanese Utility Model Publication No. 49-47606).

[0005] This type of truck has only one track, has poor running stability, and has only one track. Cannot be implemented. Further, since the single track is sandwiched between the upper roller and the lower roller, it is not suitable for traveling on a curved portion.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drive device for steep slopes of a general transporting vehicle which transports a relatively large amount of material, which can be easily processed and mounted and can be applied to a curved portion.

[0007]

According to the present invention, left and right 1
A single fixed rail having a large number of fixed claws provided on the upper surface between the pair of rails, and a carrier having two pairs of front and rear wheels rolling on the pair of left and right rails; Has a pair of left and right driving sprockets driven by a driving motor via a speed reducer, and a pair of left and right driven sprockets provided behind the driving sprocket, and a pair of left and right roller chains between the driving sprocket and the driven sprocket. Is wound, a roller is provided at the center of a roller shaft that supports each roller of the pair of roller chains in common, and the roller meshes with a fixed claw of the fixed rail with a large clearance.

[0008]

In the drive device for a steep slope of a transport vehicle constructed as described above, a roller chain according to a known technique can be easily obtained, and a fixed claw can be easily processed.

Further, since a large clearance is provided between the roller and the fixed claw, the positioning and mounting of the roller with respect to the fixed claw are extremely easy, and the present invention can be easily applied to running on a curved portion. be able to. Also,
A pair of right and left rails are provided separately from a driving means such as a fixed rail on which the fixed claws are erected and rollers engaging with the fixed claws. Since the vehicle has the wheels described above, the present invention can be applied to a general transport vehicle that travels stably and transports a relatively large amount of materials.

[0010]

1 to 3, a drive motor 2 is provided inside a steep transfer vehicle generally indicated by 1. An output shaft 3 of the motor 2 is connected to an input shaft 6 of a speed reducer 5 via a coupling 4.

A pair of right and left drive sprockets 8 are fixedly mounted on an output shaft 7 of the speed reducer 5 which is orthogonal to a rail 17 to be described later. A roller chain 10 according to a known technique is wound between a pair of left and right driving sprockets 8 and a pair of left and right driven sprockets 9 provided behind the driving sprockets 8.

Roller 1 of a pair of left and right roller chains 10
In the center of each of the roller shafts 12 that commonly support 1,
A roller 13 is provided, and is guided by an upper guide 14 and a lower guide.

A pair of right and left rails 17 on which two pairs of front and rear wheels 16 of the carrier 1 roll are provided. A fixed rail 18 is laid between the sails 17 at a position facing the roller 13, and on the upper surface of the fixed rail 18,
A number of fixed claws 19 are provided upright. And roller 1
3 engages with the fixed claw 19, and the roller 13 and the fixed claw 19
Between them, a large clearance C is formed.

Next, the operation will be described. When the driving motor 2 rotates forward and backward, the roller 13 rotates forward and reverse, and the carrier 1 moves forward and backward by the reaction force of the fixed claw 19 acting on the roller 13.

Further, since there is a large clearance C between the roller 13 and the fixed claw 17, even on the curved portion of the rail 17, the transport vehicle 1 is fixed by the roller 13 and the fixed claw 19.
Moves forward and backward.

[0016]

The present invention is configured as described above and has the following effects.

The roller chain can be easily obtained by a known technique, and the fixing claws can be easily machined, the mounting work can be easily performed, and the total equipment cost can be reduced.

Further, since a large clearance is provided between the roller and the fixed claw, the positioning and mounting of the roller with respect to the fixed claw is extremely easy, and the present invention can be easily applied to running on a curved portion. be able to. Also,
A pair of right and left rails are provided separately from a driving means such as a fixed rail on which the fixed claws are erected and rollers engaging with the fixed claws. Since the vehicle has the wheels described above, the present invention can be applied to a general transport vehicle that travels stably and transports a relatively large amount of materials.
