CZ11377U1 - Support for the central belt conveyor part - Google Patents

Description

Technical field

The technical solution concerns the central part of the belt conveyor for long-distance belt transport, for the surface mining of brown coal and overburden overburden. This part interconnects the mining site or the skids with the drive station of the conveying device by a set of non-commanding intermediate parts.

Background Art

The prior art support for the central part of the belt conveyor consisted of a welded construction of the uprights for fastening the upper garland and lower garland rollers of the conveyor and thus a special construction of the run-on parts on the side of the driving station and on the side of the mining device. This method represents an increased material and cost-intensive workload by being made of individual sheet metal parts and welded joints.

The essence of the technical solution

The new support for the central belt conveyor support is based on a simple web construction, for example, using an H-shaped rolled profile without the need for additional reinforcement parts. Such a web fully corresponds to the required rigidity and robustness for the function of the upper and lower garland rollers. By assembling the supports of the central part of the belt conveyor into a pair, a non-binding central part is formed, which then forms the central part of the belt conveyor by repeated insertion. Supports for the center belt conveyor with this structure fully enable the arrangement of the required spacing modules to provide the desired belt gauge at service load.

In addition, this design allows them to be used as run-in parts, simply by height adjustment and specific modification for the run-in part.

The required support spacing modules of the intermediate portions of the belt conveyor are provided with respective dimensions of the cross members of the non-binding center piece as the assembly.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic illustration of a complete support for a central section of a belt conveyor with individual control parts.

Fig. 2 shows the location of the web in cross-section, as an H-shaped profile and a cross-bar connection.

FIG. 3 schematically illustrates the cross-connection of the supports of the central parts of the belt conveyor and thus the arrangement of the non-binding central part as the assembly.

FIG. 1 is a diagrammatic dashed representation of the positioning of the transfer roller on the support of the central part of the belt conveyor as it is used as a non-binding central part for the conveyor belt wiper.

Example of execution

The arrangement of the support of the central part of the belt conveyor as a whole is shown schematically in Fig. 1, where the web 1 is anchored to the sleeper 2, the simple H-shaped shape of which is shown in Fig. 3 and Fig. 2. and there are provided grips for the lower garland rollers 8, for the suspension lyre 3, for operating the upper garland rollers 10 in the event of their operating failure and the hooks 11 for guidance

-1 CZ 11377 Ul of electrical cabling. Stools 5 are welded on both sides of the sleeper 2 for free loading of the handling rail 6.

The required spacing distances V, as indicated in Fig. 3, are achieved by the respective cross-bar lengths 4 attached in Figs. 2 and 3 to webs 1 and interlocked by joint 9.

By assembling the supports of the central parts of the belt conveyor, a non-binding central part is formed with the necessary spacing module according to the requirements of the conveyor belt deflection 7.

For cleaning the conveyor belt 7, a transfer cylinder 12 is shown instead of the lower garland rollers 8, indicated by a dashed line in FIG.
