Definitions

  • the invention relates to a floor conveyor, in particular a truck-mounted forklift with at least three wheels.
  • Floor conveyors of this type are used for picking up and transporting loads.
  • a forklift be the loads with a fork that is usually has two prongs, picked up and transported.
  • Lorry mounted forklifts are comparatively small forklifts, which are characterized by the fact that they are Trucks can be taken. To do this, preferably Lorry stacker with its fork in special recesses of the truck and then pulls itself on the truck locked fork high and can in this way on the truck be transported.
  • Such forklifts can do three or have four wheels.
  • the three-wheel construction is preferred for vehicles. Are two wheels are provided in the front area, i.e. the fork, while a wheel is arranged in the center of the rear is. Especially with larger floor conveyors the four-wheel construction preferred.
  • the invention has for its object a floor conveyor of the type mentioned at the beginning, that it is particularly versatile and flexible.
  • the tracking wheels can also be used as rail wheels are designated and are in particular designed such that next to a tread on an edge of the tread a section with an enlarged diameter is formed, which rests on the inside of a rail and the guidance wheel on the rail in this way leads.
  • the wheels and the tracking wheels are relative height adjustable to each other. This ensures that the industrial truck can drive on normal wheels or after being run on a rail this way or has been set in some other way and the tracking wheels relative to the normal wheels in height have been adjusted and the floor conveyor on the rail has been discontinued there using the guidance wheels can continue. This way one becomes special universal floor conveyor, in particular such a truck-mounted forklift.
  • the tracking wheels are individually height-adjustable train. Every guidance wheel is therefore individually adjustable, so that depending on the situation and the local requirements, for example first the front and then the back Guidance wheels or only the guidance wheels of some, for example the right side, and then the tracking wheels the other side can be lowered. Also an individual, differently strong lowering the tracking wheels is possible, for example, to a certain point on a slope lies in lowering the tracking wheels so differently, that the floor conveyor is leveled again is. In principle, however, it is also conceivable that Training wheels to be height adjustable and the guidance wheels to be arranged stationary. It is also conceivable that both the tracking wheels as well as the normal wheels are each one piece adjustable in height.
  • a drive device is provided with which both Wheels and the tracking wheels are drivable.
  • Prefers are a drive device for the wheels and a connecting device is provided with which the tracking wheels can be driven by the drive device of the wheels are.
  • Other power transmission options between the drive device and the various Wheels, for example with appropriate transmission devices, are conceivable.
  • Particularly preferred is, however, at least one tracking wheel, but preferred two tracking wheels to connect with a friction wheel, which in turn is powered by one of the forklift wheels is.
  • Such a construction is special simple and enables the truck to be driven on the tracking wheels with the normal wheel drive, which is transferred to the tracking wheels.
  • the Hydraulically height-adjustable tracking wheels there are those required to operate the tracking wheels Hydraulic cylinders connected to the same hydraulic system like the one or more hydraulic cylinders with which the fork the forklift is operated. So it's just one Hydraulic system necessary or it can already in used hydraulic system are, so that the operation of the tracking wheels is particularly easy.
  • the tracking wheels are attached to a linkage, that about a pivot axis upwards respectively is pivotable below, so that this linkage of hydraulic cylinders can be moved up or down.
  • the Front tracking wheels are preferred over the front ones Wheels positioned, with a hydraulic cylinder below the rest position of the tracking wheels arranged is so that for swiveling down the front tracking wheels one or one hydraulic cylinder each is to be entered.
  • the rear tracking wheels are also preferably positioned in front of the rear wheel.
  • the hydraulic cylinders are preferred arranged above the tracking wheels, so that the Swing the rear tracking wheels down or one hydraulic cylinder each is to be extended. All Tracking wheels are preferably suspended individually. Through the individual suspension and control of the tracking wheels is the individual actuation and height adjustment the tracking wheels are particularly simple. In particular the two front tracking wheels are single suspended.
  • a control device is used to lower the tracking wheels with which the guidance wheels are targeted can be operated individually. For example it is particularly preferred to start with the front tracking wheels and then put down the rear tracking wheels. In another particularly preferred embodiment are the tracking wheels of some Side and then the steering wheels of the other side lowered. This can be done using the control device either individually or in pairs by executing specified ones Programs are carried out.
  • a forklift 1 is shown in front view. Located between the two front wheels 3 and 4 the fork 2 by a mast 24 on and can be moved.
  • the mast 24 is also like wheels 3 and 4 on the structure 15 of the forklift 1 arranged, which is not explained in detail here becomes.
  • tracking wheels 6, 7 In front of the front wheels 3 and 4 are tracking wheels 6, 7 arranged, which in comparison to the wheels 3, 4 are slightly offset to the inside. These tracking wheels 6, 7 are designed to run on a rail.
  • the tread on the guidance wheel 6 is therefore exemplary 27 and one on the inside of the steering wheel 6 provided section 28 with an enlarged diameter characterized, which serves the tread 27 on the Hold rail and slide off the rail too prevent.
  • the tracking wheels 6, 7 are with shafts 16, 17 with friction wheels 11, 12 connected in the lowered position shown rest on the wheels 3, 4, so that when lowered Tracking wheels 6, 7 these are on the rail, with the result that the wheels 3, 4 are in the air.
  • the wheels 3, 4 can be driven by the motor become and move the tracking wheels over the friction wheels 11, 12 6, 7.
  • FIG. 2 is a schematic plan view of an inventive Industrial truck, which here as a forklift 1 is shown, the structure 15 and others Elements only shown in outline or omitted were so that the essential elements of the chassis are visible.
  • the fork 2 is arranged centrally in the front area is.
  • the wheels 3, 4 are in the front area and in front of it and a little bit inwards the guidance wheels 6, 7 arranged.
  • the tracking wheels are with Friction wheels 11, 12 connected when lowering the tracking wheels 6, 7 are positioned so that they are in frictional contact stand with the wheels 3, 4, so that by the drive device 13 the wheels 3, 4 via the shaft 14 also drives the friction wheels 11, 12 set in rotation are, so that then the tracking wheels 6, 7th are driven.
  • a single one Wheel 5 is provided, which is arranged centrally. This is also used for control and is therefore steered, however usually not driven.
  • tracking wheels 8, 9 that are accurate like the front tracking wheels 6, 7 hung individually are.
  • FIG. 3 is a side view of the invention Forklift shown using the tracking wheels are in the raised position.
  • Fig. 3 a front area shown in longitudinal section, so that the Inside of a front wheel is visible.
  • the tracking wheel 6 with a pivot arm 18 pivotable on a pivot axis 19 is hung.
  • One below the Swivel axis 19 on the structure 15 arranged hydraulic cylinder 20 accesses the swivel arm 18 and holds the tracking wheel 6 with the hydraulic cylinder extended in the raised position so that by retracting the hydraulic cylinder 20 the tracking wheel 6 is lowered.
  • FIGS. 3 and 3 a a schematic side view of the forklift according to the invention 1, with the tracking wheels in the lowered position. Detects in the rear area one the swivel arm 21 folded down, the is pivotable about a pivot axis 22 and at its lower End of the tracking wheel 9 is arranged. A hydraulic cylinder 23 above the pivot axis 22 the housing 15 is arranged, the tracking wheel pivots 9 when extending from the raised position the rear wheel 5 in a lower position, the is below the wheel 5.
  • Fig. 4 a is as in 3 a the front area shown in longitudinal section, so that the inside of a front wheel is shown.
  • the hydraulic cylinder arranged below the pivot axis 19 20 is retracted and in this position the tracking wheel 6 pulled down, which also Friction wheel 11 has come to rest on wheel 4.
  • the hydraulic cylinder is supplied by hydraulic hoses 26.
