Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable, in particular, relates to a flat cable for a dragline reel. BACKGROUND

[0002] The dragline reclaimer is a kind of continuous conveying high-efficiency loading and unloading machinery for large-scale dry bulk material yard, which is composed of a tiltable and horizontally oscillating belt conveyor arm, a dragline at the front end of the arm, a frame and a running mechanism. The belt can run in both directions. When taking materials, the materials are taken by the dragline and sent out through the conveyor arm. When stacking materials, the materials transported by the main conveyor are thrown to the yard through the conveyor arm. The flat cable for a reel is a flat structure electrical connection cable specially designed for heavy mobile mechanical equipment with reel and reel winding device. It has the characteristics of high mechanical stress and flexibility, and is suitable for various high stress environments. It is mainly used in occasions that require frequent bending and movement, such as power supply and control of heavy equipment such as cranes and travelling cranes.

[0003] In the existing cable used by the dragline, only the internal part of the cable is added with different materials for protection, which cannot quickly connect the cable when the length of the cable is not enough, cannot speed up the work speed of the workers and reduce the downtime of the equipment, cannot quickly protect the connection part of the cable, cannot reduce the risk of current leakage and electric shock, and cannot prevent the problems of poor contact caused by oxidation, corrosion and other problems at the wire joint.

[0004] There is no flat cable for a dragline reel that can quickly connect the cable when the length of the cable is not enough, reduce the time needed to peel the outer skin, and protect the connection part of the cable after connection. Content of the utility model

[0005] The content part of the present application is used to introduce the concept in a simple form, which will be described in detail in the specific embodiment part. The content part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0006] To address the technical problems mentioned in the background section above, some embodiments of this application provide a flat cable for a bucket wheel excavator reel, comprising: an outer protective layer, an outer insulation layer inside the outer protective layer, a filling layer inside the outer insulation layer, a core assembly inside the filling layer, a protective sleeve covering the surface of the core assembly, a clamping top block on the upper surface of the protective sleeve, a clamping bottom block on the lower surface of the protective sleeve, a fixed top shell connected to the upper surface of the clamping top block by fixing bolts, a fixed bottom shell connected to the lower surface of the fixed top shell by a connector, and a protective cover on one side of the fixed bottom shell.

[0007] During the work or installation process, due to the function of the protective sleeve structure, it can facilitate workers to quickly connect cables when the cable length is insufficient, reduce the time required to strip the outer sheath, and quickly protect the cable connection after connection.

[0008] Furthermore, the core assembly includes a conductor, a shielding layer, an inner protective layer, and an inner insulating layer. The surface of the conductor is provided with a shielding layer, the surface of the shielding layer is provided with an inner protective layer, and the surface of the inner protective layer is provided with an inner insulating layer.

[0009] Furthermore, the lower surface of the clamping top block is provided with a top groove, and the upper surface of the clamping bottom block is provided with a bottom groove.

[0010] Furthermore, the top groove and the bottom groove are the same size, and the number of the top groove and the bottom groove is three.

[0011] Furthermore, the upper surface of the clamping top block is provided with a top threaded hole, and the interior of the fixed top shell is provided with a top shell hole, and the top threaded hole is compatible with the fixing bolt.

[0012] Furthermore, the lower surface of the clamping block is provided with a bottom threaded hole, and the interior of the fixed base is provided with a base hole, the bottom threaded hole being compatible with the bottom bolt.

[0013] Furthermore, the fixed top shell has four fixing seats on both sides, and the fixed bottom shell has four fixing seats on both sides.

[0014] Furthermore, the upper surface of the fixed base shell is provided with a clamping block, and the fixed base shell and the clamping block have the same length.

[0015] Furthermore, the connector consists of connecting bolts and connecting nuts, and the number of the connectors is four.

[0016] Furthermore, the fixed top shell and the fixed bottom shell are the same size, and the clamping top block and the clamping bottom block are the same size.

[0017] The beneficial effects of this application are: it provides a bucket wheel excavator reel flat cable that is convenient for workers to quickly connect when the cable length is insufficient, reduces the time required to strip the outer sheath, and can quickly protect the cable connection after connection.

[0018] By removing the protective cover on one side of the fixed top and bottom shells, and opening the connector to separate the fixed top and bottom shells, the clamping top and bottom blocks are removed, exposing the wire core assembly. Workers then connect the exposed wire core assembly to the disconnected cable. When the cable length is insufficient, the fixed top and bottom shells can be quickly opened to expose the wire core assembly and connect it to the disconnected cable. This allows for quick cable connection when the cable length is insufficient, facilitating faster work and reducing the time required for stripping the outer sheath. A protective sleeve is then fitted onto the surface of the wire core assembly. After the worker connects the wire core assembly to the other end of the cable, the protective sleeve is applied to the wire core assembly. The sheath is pulled to the connection point to protect it, providing quick and tight protection. It tightly wraps around the terminal block, preventing damage to the connection point caused by external environmental factors such as moisture and corrosion, ensuring stable power transmission. By placing the clamping top and bottom blocks on the cable connection point and then fitting the fixed top and bottom shells over them, the connection point is quickly protected, reducing the risk of current leakage and electric shock. Especially in humid or corrosive environments, it significantly improves electrical safety, preventing poor contact at wire joints due to oxidation and corrosion, and extending the lifespan of the wire.

A clamping top block 6 is provided on the upper surface of the protective sleeve 5, and a clamping bottom block 7 is provided on the lower surface of the protective sleeve 5. A top groove 601 is provided on the lower surface of the clamping top block 6, and a bottom groove 701 is provided on the upper surface of the clamping bottom block 7. The top groove 601 and the bottom groove 701 are of similar size. The top groove 601 and bottom groove 701 are three in number. The upper surface of the clamping top block 6 is connected to the fixed top shell 9 by fixing bolts 8. The upper surface of the clamping top block 6 has a top threaded hole. The interior of the fixed top shell 9 has a top shell hole. The top threaded hole is compatible with the fixing bolts 8.
