Abstract

Traverse for turning a load, consisting of a drive element with at least one rotatably mounted radially symmetrical rotation body and at least one load-receiving endless loop element, wherein the at least one loop element runs over the at least one rotation body and is driven by this and the load due to its own gravity in the rest at least one loop element and a handle of the load can be due to a rotational movement of the rotary body.

Description

The invention relates to a turning bar with at least one loop element and such an element.

Turning with at least one endless loop element, which is rotatably mounted, run over a rotatably mounted radially symmetric body of revolution and serve to handle loads, have long been known, such as from DE 29 46 958 A1 or the DE 3007 289 A1 ,

In the past, however, it has been found that the handle of the load, which rests in at least one endless loop member due to its own severity, is problematic in that, in a turning operation of a load, there is insufficient adhesion between a surface of the load and a bearing surface of the load Loop element comes to slip and so does not occur synchronous transmission of the rotational movement of the rotating body to the load. This is especially the case when the at least one loop element has reached its wear limit, but this has not yet been reached.

It has also been found that a handle of non-radially symmetrical loads turns out to be difficult, because if there is only a point contact surface of the load on the at least one loop element there is insufficient static friction between the load and the loop element.

It is also problematic if the endless loop element is provided with a protective cover which has an outer surface structure. Then there is the danger that protective tubes or sleeves slip.

The invention has the object to improve the handle of a load, in particular a non-radially symmetrical load by means of a turning bar. The object is achieved by the features of the main claim 1 and the secondary claim 6, wherein further embodiments of the dependent claims follow. Thereafter, the traverse according to the invention for turning loads and the inventive loop element has the following features.

The traverse consists of a drive element, such as a motor, with at least one rotatably mounted radially symmetric rotation body and at least one load-receiving endless loop element, the at least one loop element via at least one rotary body, one or more drive wheels or other suitable components, running and of this is driven and the load due to its own gravity in the at least one loop element can rest. A handle of the load can be done due to a rotational movement of the rotary body. According to the invention, an inner surface of the loop element has elevations which are arranged substantially at an angle to the long side of the loop element and extend over the entire width of the inner surface of the loop element.

The elevations may be arranged, for example transversely, ie 90 ° or diagonally, about 45 ° to the long side of the loop element. These arrangements can also alternate, so in sections.

In a further embodiment, the elevations may extend in a radial, wavy and / or curved manner over the entire width of the inner surface of the loop element, depending on the requirements of the environmental conditions, such as the load to be transported.

The at least one rotation body is adapted. Its running surface corresponds to the shape of the inner surface of the loop element as in a toothed belt and a pulley or pinion corresponding thereto.

The elevations have a convex shape in cross-section with respect to the long side of the loop element.

It can also be provided that the elevations with respect to the long side of the loop element have a semicircular or a semi-elliptical cross section.

Due to the embodiment of the invention, an optimized traverse is provided, in which the static friction between the load and loop element is improved. Since protective covers for loop elements do not exist, one component is eliminated. Costs are minimized and due to the reduction of components, there is no risk that slippage of the components can take place relative to each other.

The invention will be explained below with reference to an embodiment with reference to the figures. This results in further advantages, features and embodiments of the invention.

• 2 a fragmentary view of a loop element.

In 1 , is a traverse 1 , A turning beam according to the invention, shown, which consists of a drive element 2 with a rotatably mounted radially symmetric rotation body 3 and one the load 5 receiving endless loop element 4 consists.

The loop element 4 runs over the rotation body 3 and is driven by this. A burden 5 rests due to its own severity in the loop element 4 ,

The loop element 4 takes the load 5 on. A handle of the load 5 can due to a rotational movement of the rotating body 3 respectively.

According to the invention, an inner surface 6 the loop element 4 surveys 7 , which is perpendicular to the long side 8th the loop element 4 are arranged. They run radially over the entire width of the inner surface 6 the loop element 4 . 1 ,

As from a sectional view, 2 , the surveys show 7 . 7 ' and 7 " the loop element 4 in relation to the long side 8th the loop element 4 in a cross section 9 convex and are configured in the embodiment substantially semicircular. The rotation body 3 is in the embodiment of the cross section 9 the surveys 7 So the shape of the surveys 7 customized. Its running surface corresponds with the shape of the inner surface 6 the loop element 4 similar to a timing belt.
