Description

Wheel manipulator DESCRIPTION: 5

FIELD OF THE INVENTION

The invention relates to a wheel manipulator comprising a frame provided with a vertical guide, a slide which is slidable along the guide, at least two arms which are each connected with a first end to the slide and which are provided with a second end at the second end. holding element for holding a wheel. A vertical guide should be understood to mean any guide that is not completely horizontal.

Wheel manipulators are used, among other things, for exchanging large, heavy wheels of, for example, tractors. These wheels are heavy and can hardly be changed manually or not at all. The wheel manipulators are usually movable by wheels located under the frame and a drawbar attached to the frame. With the wheel manipulator a wheel can be moved in height, by sliding the carriage along the guide, and be moved in its entirety, because the wheel manipulator can be moved in its entirety. In addition, the arms are usually mounted on a carrier that is rotatable about an imaginary central axis, whereby the wheel is rotatable to enable the bolt holes in the wheel to be accurately inserted into a wheel carrier for further bolt holes or thread ends.

Prior art.

Such a wheel manipulator is known from Dutch patent application No. 8902989. For gripping wheels of different sizes, this wheel manipulator has three arms, the length of which is adjustable because they are formed by two telescopically slidable profiles.

Summary of the invention.

An object of the invention is to provide a wheel manipulator of the type described in the preamble wherein the mechanism for holding a wheel is improved. To this end, the wheel manipulator according to the invention is characterized in that the arms are rotatably connected to the carriage at the location of the first ends. As a result, wheels of different diameters can also be clamped with arms of unchanging length.

An embodiment of the wheel manipulator according to the invention is characterized in that the wheel manipulator comprises means for synchronously rotating the arms. As a result, the center between the retaining elements present at the second ends of the arms is always at the same place, which is preferably located in front of the opening in the carriage.

A constructionally favorable embodiment of the wheel manipulator according to the invention is characterized in that the means for synchronously rotating the arms comprise chain wheels which are attached to the first ends of the arms, as well as a chain which is wrapped around the chain wheels. Furthermore, the means for synchronously rotating the arms preferably comprise a cylinder-piston combination, which is attached with one end to the carriage and with the other end to the chain. The cylinder is preferably a hydraulic cylinder wherein the supply of oil under pressure is preferably done manually with a hand pump.

A further embodiment of the wheel manipulator according to the invention is characterized in that the wheel manipulator comprises means for holding the retaining elements in the same position during rotation of the arms. Preferably, the means for holding the retaining elements in the same position comprise a rod mechanism which, together with the arm, forms a parallelogram construction. As a result, the orientation of the retaining elements remains the same during rotation of the arms.

A further drawback of the aforementioned known wheel manipulator is that it is difficult to remove a wheel from a wheel axle and to fix it on a wheel axle because the middle part of the wheel where the bolt holes are located is difficult to access due to the presence of the guide and the carriage for the center of the wheel.

A still further embodiment of the wheel manipulator according to the invention, in which this drawback does not occur, is characterized in that, while a wheel is being held, the center of the wheel is in front of the carriage, the carriage being provided with an opening which is in front of the center of the wheel. Through this opening the center of a wheel is freely accessible so that the wheel nuts or wheel bolts can easily be loosened or tightened.

In order to also be able to easily detach large wheels from a vehicle and to fix them onto a vehicle, the opening preferably has dimensions such that it encloses an imaginary circle with a diameter of at least 30 cm, preferably at least 50 cm. To this end, the guide preferably comprises two parallel vertical guide profiles, which are present at a distance of at least 30 cm, preferably at least 50 cm, from each other.

Brief description of the drawings.

The invention will be explained in more detail below with reference to an exemplary embodiment of the wheel manipulator according to the invention shown in the drawings. Hereby shows:

Figure 1 shows an embodiment of the wheel manipulator during the holding of a wheel in side view; Figure 2 shows the wheel manipulator with wheel in front view;

Figure 3 shows the wheel manipulator with wheel in top view; and

Figure 4 shows the wheel manipulator in front view but now with a smaller wheel.

Detailed description of the drawings.

25

Figures 1, 2 and 3 show an embodiment of the wheel manipulator 1 according to the invention while holding a wheel 3 in side view, front view and top view, respectively. The wheel manipulator 1 has a mobile U-shaped frame 5 with a vertical guide 7 thereon, which is formed by two spaced apart vertical guide profiles 9, 11. Between the guide profiles there is a slide 13 which is slidable along the guide. The carriage is coupled to a vertical hydraulic cylinder 15 which is connected to a hand pump 17.

An annular disc 19 is rotatably mounted on the carriage 13 and can be rotated manually. Three shafts 21 are mounted on the disk on which sprockets 23 and arms 25 are mounted. A chain 27 is wrapped around the chain wheels 23 and can be displaced by a further hydraulic cylinder 29. This further hydraulic cylinder is also coupled to a hand pump 31. The arms 25 are attached to the shafts 21 with a first end 25a. Retaining elements 33 for retaining the wheel 3 are attached to the second ends 25b of the arms. The chain 27 with the sprockets 23 and the hydraulic cylinder 29 form means for synchronously rotating the arms 25.

By rotating the arms 25, the retaining elements 33, which are rotatably present on the arms, enclose a smaller circle so that wheels with a smaller diameter can be held. The retaining elements 33 are mounted on shafts 33b which are rotatably mounted in the arms 25.

These shafts 33b are connected via a rod mechanism 34 to the disc 19. Each rod mechanism has a rod which is parallel to the arm 25 and rotatably connected at one end to the disc 19 and pivotally connected at the other end to a connecting rod which is mounted on the shaft 33b. In this way a parallelogram construction is obtained whereby the orientation of the retaining elements 33 remains the same during rotation of the arms 25.

To clarify the operation of the wheel manipulator 1, the wheel manipulator with a smaller wheel 35 is shown in Figure 4 (for the sake of clarity, the rod mechanisms 34 are not shown here). The arms 25 here have the same length but are rotated with respect to the position shown in figures 1, 2 and 3, which is shown herein with broken lines.

The arms 25 are formed by two telescopically slidable sleeves 37 which can be fixed relative to each other by means of a pin 39. The length of the arms 25 can hereby be changed, whereby even larger or smaller wheels can be held.

In the middle of the carriage 13 there is a large circular opening 41, see figure 2. The opening in the carriage is situated midway between the retaining elements 33. Through this opening 41 the center of the wheel 3 is freely accessible so that the wheel nuts or wheel bolts can easily be loosened or tightened. In order to have good access to the bolt openings in a wheel even with 5 large wheels, the opening 41 has a diameter of approximately 70 cm and the distance between the vertical guide profiles 9, 11 is approximately 1 meter.

The wheel manipulator 1 can be driven with the aid of a drawbar 43 which is coupled to one of the wheel pairs 45, wherein when the drawbar 43 is rotated this pair of wheels also rotates, see figure 3.

Although in the foregoing the invention has been elucidated with reference to the drawings, it should be noted that the invention is by no means limited to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the scope defined by the claims.
