Reversible paddle wheel

The invention relates to a paddle wheel in which the direction of rotation and thus the side on which material is removed can be reversed.

Paddle wheel devices with a reversible paddle wheel are primarily used as

Paddle wheel reclaimers, paddle wheel bridge reclaimers, drum reclaimers and the like are used. While in the actual opencast mine a constant mining front is always preferred, a constant mining direction and therefore always the same direction of rotation of the bucket wheel are always piled up in the storage area and dismantled again using a reclaimer. The reclaimer is usually used between two heaps, one is built up and one through the

Reclaimer dismantled. This means that at regular intervals the...

Mining direction is changed. For this purpose, the direction of rotation of the blade wheel is usually changed by manually releasing the individual blades, folding them over and attaching them again. The blades usually have two for this purpose

Knife cutting, one for each direction of rotation and a support rod that supports the

Absorbs digging forces from the bucket and transfers them to the bucket wheel. Due to the large forces, the support rods are connected with bolts that are at each

Change of direction must be loosened and reattached. Even if this one

If the process only needs to be carried out at intervals, this will be accelerated

The process ensures greater availability of the reclaimer and therefore, above all, a more constant material flow.

Since the knife edges deform due to wear, the knife edges cannot be used for a frictional connection between the blade and the wheel ring body. A support rod is therefore used to transfer the forces from the blade to the wheel ring body.

The object of the invention is to provide a paddle wheel in which the process of

Reversal of direction is simplified and accelerated.

This task is solved by the paddle wheel with those specified in claim 1

characteristics. Advantageous further developments result from the subclaims, the following description and the drawings.

The paddle wheel according to the invention is a paddle wheel in which the direction of rotation and thus the side of the mining front can be reversed. Such paddle wheels are particularly used in paddle wheel reclaimers, paddle wheel bridge reclaimers,

Drum reclaimers and the like are used. The paddle wheel has one

Edge ring body. The edge ring body is the circular supporting component to which the blades are attached. The paddle wheel has at least one first

Shovel up. The blade wheel usually has a plurality of blades, with the additional blades being designed in the same way as the first blade and also having the other features according to the invention. The first blade has a first

cutting side and a second cutting side. The first cutting side is used for

Removal of the material in the first direction of rotation, while the second cutting side to

Removal of the material in the opposite direction of rotation is used. The first blade can roughly have the shape of a quarter circle, with the first cutting side being arranged on one straight side and the second cutting side being arranged on the other straight side. The first blade is rotatably connected to the edge ring body.

This results in a folding over and thus a change in the direction of dismantling

Change of direction of rotation possible. In the case of a shovel in the shape of a

Quarter circle is the rotating attachment between the first blade and the

Edge ring body arranged in the area of the center of the circle forming the fourth circle. The paddle wheel has at least a first support rod. The

The support rod serves in particular to transmit the digging forces into the edge ring body. The paddle wheel has at least a first stop point and a second stop point. An anchor point is used to create a connection

To be able to set up the support rod and then with an existing connection with the

Support rod to transmit the forces into the edge ring body. Usually the

Connection between the anchor point and the support rod is made using a bolt.

The first stop point and the second stop point are connected to the edge ring body or are formed by it. For example, they can

Stop points must be welded onto the edge ring body. Alternatively, they can

) BE2022/5089 must be formed. The first stop point and the second stop point are arranged on the opposite sides of the first blade, the first stop point thus serves to connect to the support rod in the first direction of rotation and the second stop point to connect to the second, opposite to the first

Direction of rotation. The first support rod is connected to the first blade, for example and in particular rotatably connected to one another, preferably to one

Bolt. The first support rod is with the first anchor point or the second

Attachment point connectable. Depending on the direction of rotation, the first support rod is then connected to the first stop point or the second stop point in a specific situation. To fold over the first shovel, the connection between the first support rod and the anchor point connected to it is released, the first

Shovel and the support rod folded over and the connection between the first

Support rod and the other anchor point made.

According to the invention, the first support rod is positively coupled to the edge ring body of the blade wheel by means of a positive locking element. The form-fitting connection through the form-fitting element ensures that they are kinematically connected to one another in such a way that when the first one is folded over

In a further embodiment of the invention, the paddle wheel has a first

Support element and at least one first guide rod. The first support element is firmly connected to the edge ring body. The first guide rod is connected to the first support rod on one side and is connected to the first support element on the opposite side. The first support element and the first guide rod thus form the positive locking element. This means that the first guide rod guides the first

Support rod when folding the first shovel. This leads to this

The process does not have to be carried out manually, which in turn speeds up the process and increases safety, as the presence of one

Support rod, a third anchor point and a fourth anchor point, a second

Guide rod and a second support element. The second support rod is connected to the first blade. The second support rod can be connected to the third anchor point or the fourth anchor point. The second guide rod is on one

Side connected to the second support rod and is connected to the second support element on the opposite side. The first guide rod and the second

Guide rods are arranged on opposite sides of the first blade.

The first support rod and the second support rod are therefore also arranged on opposite sides of the first blade. This allows a better

Stabilization of the first blade through a more distributed power transmission to the blade

Edge ring body can be achieved. Additionally, the first support rod and the second

Support rods can be connected to each other, for example through a pipe grid

Uniformity of power transmission.

In a further embodiment of the invention, the paddle wheel has a first

Spring element. The first spring element is connected to the first guide rod

1 to 6, a portion of a first exemplary blade wheel is shown with only one exemplary blade 20 shown, the blade 20 being folded over by the sequence shown in FIGS. 1 to 6.

In Fig. 1 an initial position is shown in which the paddle wheel is rotated

Clockwise on the left side can mine material.

Shown below is a section of the edge ring body 10. The approximate size of the entire blade wheel is determined based on the curvature. For simplicity, only one blade 20 is shown. In particular, the first stop point 40 of the first blade 20 can be the second stop point 41 of a second blade 20 or vice versa.

The blade 20 has a first cutting side 21, which is shown in FIG

Position for active material removal is arranged, and a second cutting side 22 which is arranged in an internal position. In order to be able to switch between the two dismantling positions, the shovel 20 is rotatably connected to the annular edge body 10 via the axis of rotation 23 of the shovel 20. Because the shape of the second cutting side 22 through

Wear is variable, a positive connection between the second

Cutting side 22 and the edge ring body 10 can be reliably manufactured. For the

Power transmission is therefore a support rod 30 connected to the blade 20 via a rotation axis 31. On the other hand, the support rod 30 has a dovetail 32, which engages the first stop point 40 in a form-fitting manner. The support rod 30 is held in contact with the first stop point 40 via a spring element 52.

In order to be able to fold the shovel 20 in a controlled and independent manner, the support rod is connected to a guide rod 50. The guide rod 50 is over a

Support element 51 is connected to the edge ring body 10, so that the axis of rotation is arranged further 30 up, which is advantageous for the rotation as shown in the following figures. Furthermore, a blade folding device 60 is shown above, which is in a position such that it folds the blades 20. For regular operation it can

° BE2022/5089 are spent so that no interaction with the shovel 20 occurs. For this

Interaction in the position shown has the shovel 20 two folding aids 61.

From this starting position, the blade 20 is rotated counterclockwise

Folded clockwise. To do this, the paddle wheel is turned counterclockwise.

Fig. 2 shows the beginning. The blade folding device 60 is in contact with the

Folding aid 61. This releases the dovetail 32 from the first

Stop point 40. The guide rod 50 ensures a consistent, constant and predictable movement of the support rod 30. The middle position of the rotational movement is reached between Fig. 3 and Fig. 4. In Fig. 4 the contact between the

Folding aid 61 and the blade folding device 60 ensure that the blade does not fold over in an uncontrolled manner, but is guided in a controlled manner, as can also be seen in FIG. 5. In

6, the end position is then reached and the dovetail 32 of the support rod 30 is in direct non-positive contact with the second stop point 41.

In Fig. 6, the paddle wheel can remove material by rotating counterclockwise on the right side.

In Fig. 7, a second exemplary embodiment is shown only in the first position; the other positions result analogously to the first exemplary embodiment shown. The second exemplary embodiment differs in that instead of

Guide rod 50, a connecting rod 70 with gears 71 mounted thereon is used. The connecting rod 70 has two pivot points, one on the

Axis of rotation of the blade 23 and one together with the axis of rotation between the

Support rod and the blade 31. Fixed with the edge ring body 10 is a first

Gear ring 72 connected. Likewise, the support rod 30 had a second gear ring 73 firmly connected to it. The gears 71 create a frictional connection between the first tooth disease 72 and the second

Ring gear 73 and thus achieved between the edge ring body 10 and the support rod 30.
