Description

[Detailed Description of the Invention] The present invention is a transport vehicle that is movably supported by a pair of left and right guide rails, and includes a drive gear that engages with a rack gear attached to one of the guide rails and a motor that drives the drive gear. This invention relates to a self-propelled transport vehicle equipped with a self-propelled transport vehicle, which allows a transport vehicle of the required size to be easily and inexpensively constructed by simply changing the size of the rectangular loading platform and the side cover plates on both the left and right sides. That is.

Hereinafter, one embodiment of the present invention will be described based on the attached illustrative drawings. In FIGS.
and three guide units 3 are attached to the lower four corners of the loading platform 4. Reference numerals 5 and 6 denote a pair of left and right guide rails, which are located inside each unit 2 and 3 in the transport vehicle 1, and which sandwich the rail portions 5a and 6a extending inward from the lower end from above and below. A steady rest vertical shaft roller 9 close to the inner end surfaces of the wheels 7, 8 and the rail portions 5a, 6a,
It is pivotally supported by guide rail winding portions 2a and 3a of each unit 2 and 3 of the transport vehicle 1. Reference numeral 10 denotes a support member that supports the pair of left and right guide rails 5, 6 in a cantilevered manner at its upper end, and is arranged at appropriate intervals in the length direction of the guide rails 5, 6, and Each unit 2, 3
The guide rail winding portions 2a, 3a move between this support member 10 and the guide rails 5, 6.
Reference numeral 11 denotes a cover plate installed between the upper ends of the pair of left and right guide rails 5 and 6.

The drive unit 2 of the transport vehicle 1 has a reducer 12 mounted on a support section 2b extending inward from its lower end, and a drive gear 13 is attached to an output shaft protruding from the reducer 12. ing. This drive gear 13 is driven by a motor 14 attached to the reduction gear 12 in the front-rear direction, and this motor 14 is supported by the guide rail support member 10 in multiple stages above and below for power supply and control signal exchange. It is driven by electric power and control signals applied from the rail 15 through a current collecting means 16 attached to the inner end of the support section 2b. Reference numeral 17 denotes a rack gear, which is attached to one side of the guide rail 5 at a position where it meshes with the drive gear 13. Reference numerals 18 and 19 denote side cover plates installed between the drive unit 2 and the guide unit 3 located in the front and back on the same left and right sides, and between the two guide units 3, and cover the entire outer surface of each unit 2 and 3. to cover.

The transport device configured as described above operates the motor 14 of the transport vehicle 1 to transport the rack gear 17.
By rotating the drive gear 13 that meshes with the carrier 1, the carrier 1 can be propelled while being guided by both guide rails 5 and 6, and the objects on the carrier 4 can be transported. However, especially according to the configuration of the present invention, as shown in FIG. By preparing the side cover plates 18 and 19, the drive gear 13 and motor 1 can be
4, and one drive unit 2 and three guide units 3 equipped with current collecting means 16 are common regardless of the size of the loading platform 4, etc., and these units 2 and 3 are connected to the loading platform. By simply attaching the side cover plates 18 and 19 to the four lower corners of the cargo platform 4 and between the units located in the front and rear on both the left and right sides, a carrier vehicle equipped with a cargo platform 4 of any size can be constructed.

In particular, since the drive gear 13, which is the conveyance vehicle propulsion means, the motor 14 that drives it, and the current collection means 16 are integrated into a drive unit that also serves as one guide unit, these propulsion means can be Compared to the case where the four guide units are directly attached to the underside of the loading platform 4, not only is the number of installation steps reduced, but the entire propulsion means can be assembled with high precision.

In addition, as shown in the embodiment, the carrier of the present invention can easily adjust the spacing between the pair of left and right guide rails 5 and 6 by using support members 10 with different spacing between the guide rail mounting portions on both the left and right sides. It is desirable to use it in conjunction with a guiding device that can be changed to
