Definitions

• the invention relates to a drag conveyor system for transporting and pulling loads in industrial plants and warehouses with the aid of a motor-driven drive unit which can be moved on running rails.
• the tow truck partially lifts the load to be transported.
• the towing vehicle comprises an uppercarriage and an undercarriage which are arranged one above the other and articulatedly connected to one another, that the undercarriage has an extendable and retractable caster rocker, at the ends of which the caster wheels are arranged, the extension being extended by the Roller rocker of the towing vehicle can be raised so that the undercarriage has laterally rigid, front pickup rollers and the uppercarriage has horizontally opening and closing rear clamping rollers assigned to the front pickup rollers at the rear end.
• the load to be transported is a motor vehicle, the front wheels of which are arranged between the rigid, front pick-up rollers and the closed, rear clamping rollers, and the front part of which can be raised by extending the roller rocker.
• the towing conveyor system can be produced inexpensively and can be easily installed both in existing and in newly constructed monorail systems in the entire assembly area, since complex and heavy gripping and lifting devices for transporting the Motor vehicles and complicated lifting and lowering stations for overcoming differences in height are eliminated. Since the motor vehicles are driven without a driver and without the engine running, downtimes and set-up times can be shortened, personnel costs and fuel saved and noise levels and pollutant loads in the conveying area reduced.
• FIG. 4 is a top view of the towing vehicle belonging to FIG. 3,
• FIG. 7 schematically shows a side view of the return of the motor vehicle from the floor conveyor to the towing conveyor system and the overcoming of a height difference by empty towing conveyor systems in the horizontal and downhill areas.
• the towing conveyor system 1 shows a schematic side view of a towing conveyor system 1 according to the invention.
• the towing conveyor system 1 consists of an electric monorail vehicle 2 which can be moved on rails 6 and which is known, for example, from DE-PS 44 01 210 and is described there, and a towing vehicle 3 which is movable on the floor 21 of factories and warehouses and is provided with corresponding rollers 11 , where the towing vehicle 3 is connected to the Eletoro suspension bogie vehicle 2 via a towing linkage 4.
• the towing linkage 4 is coupled to the monorail vehicle 2 with the aid of a coupling unit 14 only indicated in the drawing.
• the towing vehicle 3, which serves to accommodate the loads 5 to be moved, preferably motor vehicles 5, is composed essentially of an upper carriage 7 and an undercarriage 8, which are arranged one above the other and with the aid of a top view of the towing vehicle 3 in FIG. 2 designated 9 ball bearings, for. B. an angular contact ball bearing, are hinged together and form a turntable.
• the undercarriage 8 is connected to the towing linkage 4 via a drawbar 22 and has a retractable and extendable roller rocker 10 at its rear end, on the outer ends of which the roller rollers 11 are arranged.
• rigid, front pick-up rollers 13 project laterally, against which the front wheels 18 of a motor vehicle 5 run onto the towing vehicle 3 when it is picked up.
• FIG. 6 and 7 schematically show in side view the overcoming of a height difference by empty towing conveyor systems 1 in the area of a water test section through which the motor vehicles 5 are moved by a floor conveyor, not shown in the drawing.
• the towing conveyor systems 1 are conveyed into the reversing line 17 without an additional device for the riser area 27 and are returned to the electric monorail cycle circuit at the transfer position over a downward slope 32, likewise without an additional device.
