Description

[Detailed description of the invention] The present invention relates to a six-wheel balance transport vehicle used for transporting heavy items such as gravure plate cylinders. Conventionally, this type of transport vehicle was generally a hand-push type. However, the present invention is a six-wheeled balance transport vehicle with a small turning radius in which a drive device with a differential gear is provided on the central wheel. , in a six-wheel balance carrier equipped with both center wheels and both front wheels and both rear wheels with smaller diameters in front and behind the center wheels, the wheel axle 21
are provided with a central wheel 2 having a differential gear mechanism 11 and a drive device, and each table 4, which rotates freely horizontally,
5 is provided with a front wheel 6 and a rear wheel 7, respectively, the tables 4 and 5 are connected diagonally with a connecting rod, and a steering transmission gear 12 is provided on the rotation axis of the front wheel or rear wheel table, and the gear and the This six-wheel balance transport vehicle is characterized by having a steering mechanism equipped with a handle whose height can be adjusted in the vertical direction on the rotating shaft of a transmission gear that is disposed so as to mesh with the transmission gear.

In the present invention, as shown in FIGS. 1, 2, and 3, a central wheel 2 is installed at the center of a vehicle body frame 1 via a central wheel shaft 21, and the front and rear positions of the vehicle body frame 1 are The front wheels 6 and the rear wheels 7 are connected to the body frame 1 by rotating shafts 8 and 9, respectively, through rotary tables 4 and 5 on which front wheels and rear wheels are attached, respectively, which are connected by connecting rods 3 disposed diagonally. Equipped. The central wheel 2
When balanced on the fulcrum, the front wheels 6 and rear wheels 7 do not touch the floor.
The central wheel 2 is capable of self-propulsion by a drive motor 10 via a differential gear mechanism 11. or,
The rear wheel 7 includes a steering transmission gear 12 attached to the rotating shaft of the rotary table 5, and a steering transmission gear 12 attached to the rotation shaft of the rotary table 5.
A handle 13 is connected to a rotating shaft of a transmission gear 12' that meshes with the transmission gear 12'. Moreover, the handle 13 is
The handle 13 can be slid up and down by a slide cylinder 14, and the height of the handle 13 can be changed by a fixed clutch pin 15. In the drawings, 16 is an operation panel box, 17 is a control box, 18 is a battery 19 is a transport stand, and 20 is an object to be transported.

The present invention has the above-mentioned configuration, and is self-propelled by rotating the central wheel 2 by the drive motor 10 via the differential gear mechanism 11, and when turning, by turning the handle 13. The front wheels 6 and rear wheels 7 can be turned in the turning direction at the same time by means of the steering transmission gears 12, 12' and the rotary tables 4, 5 connected diagonally through the connecting rod 3. Therefore, when the vehicle is running, only one of the center wheel 2, front wheel 6, or rear wheel 7 is in contact with the floor, but no matter which wheel is in contact with the floor, the differential gear mechanism is adjusted in the direction of that wheel. can follow the center wheel 2 and turn around the inner side of the rotation of the central wheel 2 or the midpoint of the wheel axle 21 with a small turning radius. Furthermore, if the steering wheel 13 is used to balance the center wheels and the front and rear wheels 6 and 7 are lifted off the floor when steering, the steering resistance can be made extremely small, and the steering resistance can be kept balanced using the center wheels 2. It is possible to make a sharp turn by lowering the front wheels 6 or rear wheels 7 to the floor after turning in the direction of rotation at the turning point, and automatic driving is easily possible even on relatively complicated transport routes. When loading and unloading the transported object 20,
The present invention provides a practically excellent six-wheel balance carrier having a mechanism for vertically sliding the handle 13 out of the way.
