[0001] TELESCOPIC CONVEYOR WORKING GAP CLOSING GROUP BETWEEN BOOMS

[0002] Field of the Invention

[0003] The present invention relates to a gap closure group comprising a three-layer composite structure integrated with a “shine” fabric-covered sponge material to effectively close the gaps between the booms during telescopic conveyor movements, increasing operator safety and preventing damage between the crates.

[0004] In particular, the invention relates to a gap closure group that uses “shine” fabric-covered sponge material with elastic properties in a three-layer composite structure to close the gaps formed during movement in the machine structure and thus reduce the risk of jamming the hands and clothes of the operators, while fully complying with safety standards without the risk of collision between the crates, while at the same time providing a solution to protect the crates and working personnel as a result of the non-linear movement of the crates.

[0005] State of the Art

[0006] Telescopic conveyor booms are used for material handling and load lifting and movable structures that can extend and shorten and are widely preferred in construction, mining and industrial applications. Since these machines have a flexible carrying capacity, they can work effectively even in narrow spaces. Due to the structure of the machine, the booms lengthen and shorten by moving back and forth within each other. Due to the sheet metal structure, when manufacturing methods and welding are involved, the movements of the booms within the crate move away from a linear movement. The forced working gaps are likely to cause occupational accidents by pinching the operator's limbs or clothing while the crate is moving back and forth. This risk cannot be eliminated by creating safety areas, as these parts with gaps are located within the operator's work area and change position during machine movement. However, during the operation of telescopic conveyor booms, it is critical that the gaps between the booms are securely closed.

[0007] In current systems, brushes or kestamite-derived materials are usually used to fulfill the gap closure function. Although the use of a brush provides a visual gap closure, this does not eliminate the risk of hand entrapment in accordance with the machine safety regulations. In other words, the brush preferred for ease of installation can pose serious risks in terms ofsafety. The cestamite material used in standard applications prevents hands from entering the gaps. This material, which prevents the hand from entering during machine movement, damages the machine body from time to time due to the difficulty of linear operation, and when the gap adjustment is made to prevent damage, gaps (a>5mm) that do not comply with the machine safety regulations occur. Days of workmanship and adjustment are required to bring the gap to the standards in the machinery safety regulations with the cestamite material.

[0008] When cestamite-derived material is used, although a gap closure is applied in accordance with the machine safety regulations, due to the structure and sheet metal properties of the machine, the movements between the booms during operation come into contact with the cestamite material and cause scratches and defects on the machine. In some cases, adjustments may be required for days to prevent such contact. Moreover, for some machines, it becomes very difficult to provide gaps in the machine safety regulations.

[0009] Therefore, the search for an innovative and effective solution to safely close the gaps is very important. As a result, the need for a gap closing group developed for closing the working gap between telescopic conveyor booms, which eliminates the disadvantages of the existing technique, and the inadequacy of the existing solutions necessitated a development in the relevant technical field.

[0010] Brief Description of the Invention

[0011] The present invention relates to a gap closure group which fulfills the above-mentioned requirements, eliminating all disadvantages and introducing some additional advantages comprising a three-layer composite structure integrated with a “shine” fabric-covered sponge material to effectively close the gaps between the booms during telescopic conveyor movements, increasing operator safety and preventing damage between the crates.

[0012] Based on the state of the art, the object of the invention is to prevent the gap between the telescopic conveyor booms from damaging each other in case of disturbances caused by the linearity of the crates by keeping the gap between the telescopic conveyor booms within the machine safety standards thanks to the use of shine fabric covered sponge material instead of cestamite used in the existing applications in the developed closing group.

[0013] The object of the present invention is to prevent the cases from damaging each other by creating a buffer between the crates in case of approaching each other due to linearity problem thanks to the elasticity structure of the sponge.Another object of the invention is to ensure that the sponge group covering the gap with a three-layer composite structure and the closing the gap is covered thanks to shine fabric, so that the sponge does not make sound and does not interfere with the movement of the crates in case of crate contact when the crates lose linearity during the movement of the crates.

[0014] Another object of the present invention is to ensure that the sponge in the composite group is crushed in contact with the crate, eliminating the need for linearity.

[0015] Another object of the present invention is to ensure the mounting of the composite group to the booms, thanks to the rearmost sheet metal group.

[0016] Another object of the present invention is to prevent the sponge from sticking to the crate thanks to the shine fabric.

[0017] Another object of the present invention is to ensure that, thanks to the sponge material structure, the risk of hand jamming or operator clothing getting stuck even if the crates are crushed during movement is completely eliminated.

[0018] Another object of the present invention is to ensure full compliance with the machinery safety regulations, allowing the crates to work within each other, thanks to gap closure group eliminates the risk of hands or clothing getting trapped.

[0035] Detailed Description of the Invention

[0036] In this detailed description, the gap closing group (10) comprising a three-layer composite structure integrated with a “shine” fabric (12) covered sponge (14), which effectively closes the gaps (22) formed between the main boom (21) and the movable booms (23) during the movements of the inventive telescopic conveyor (20), increasing operator safety and preventing damage between the crates, is described only as an example for a better understanding of the subject matter and without any limiting effect.

[0037] The telescopic conveyor (20) comprises a main boom (21 ), which is the main conveyor section, and at least one movable boom (22) which moves within the crate of the main boom (21 ). While the telescopic conveyor (20) shown in Figure-1 is operating, a working gap (22) is formed between the movable boom (23) crates, which move back and forth within each other, extending and shortening. The gap closing group (10) that is the subject of the invention was developed to close this working gap (22) in accordance with Occupational Health and Safety (OHS) rules. The gap closing group (10) shown in Figure-2a and Figure-2b is mounted on the part where the gaps (22) are located in order to close the working gaps (22) left between the main boom (21 ) and the movable booms (23) due to the movements in the frame moving away from linear motion. The aforementioned gap closing group (10), with its composite structure comprises shine fabric (12) covered sponge (14) material, keeps the working gap (22) within the machine safety standards and prevents damage to each other in case of defects causedby the linearity of the cratees. The sponge (14) inside the composite structure shown in Figure-3a and Figure-3b prevents the crates from damaging each other by crushing when the crates approach each other due to the linearity problem.

[0038] The gap closure group (10) shown in Figure-4 includes a three-layer composite structure comprises a sheet metal group (11) positioned at its innermost part, the sponge (14) adhered to this sheet metal group (11) and the fabric (12) coated on the sponge (14). The aforementioned composite structure closes the working gap (22) by means of the sponge (14) in it, and the shine fabric (12) covered on the sponge (14) prevents the sponge (14) from making noise and preventing the crate movement in case of frame contact when the main boom (21) and movable boom (23) crates lose linearity during movement. The sponge (14) in composite structure is crushed in contacts with the crate, eliminating the need for linearity. Said composite structure was obtained by bonding the sheet group of the sponge (14) covered with shine fabric (12) with a resin. After the composite structure is formed, it is positioned in the working gaps (22) on the crate and fixed on the crate with the help of connection elements (13). Said shine is a shiny fabric material with low adhesion to the fabric material. Thanks to this fabric, the sponge (14) is prevented from sticking to the crate. Due to its material structure, the sponge (14) completely eliminates the risk of hand jamming or operator clothing getting stuck, even if it is crushed during the movement of the crates. In this way, it fully complies with the machinery safety regulations and allows the safes to work within each other. The sheet metal group (11 ) is positioned at the back of the gap closing group (10) to mount the composite structure (12) shown in Figure-5 to the main boom (21) and movable booms (23).
