Technical Field

[0001] The utility model relates to the technical field of steel transmission, in particular to a flying shear conduit structure. Background Art

[0002] The existing workshop used a disc shear with an integrated duct. This design had some flaws, such as being welded to the housing. In the event of a malfunction, the transported red steel would accumulate inside the duct, making it difficult to remove. This prolonged the malfunction. Furthermore, the lack of a cooling system in this area could easily cause burns during handling, posing a significant safety hazard. Furthermore, the original duct had a thin wall thickness of 8.5mm, which was prone to deformation due to prolonged exposure to high temperatures, ultimately resulting in scratches on the finished product.

[0003] In order to solve the problems of easy deformation of the catheter and inconvenience in disassembly when troubleshooting, which affects the production rhythm, a flying shear catheter structure was developed. Utility Model Content

[0030] like Figure 1-5The guide frame 1 is provided with a U-shaped groove 2 on its upper surface, which is used to guide and transport the red steel billet after the rolling line flying shear, and is not easy to scratch the red steel billet. The U-shaped groove 2 runs through both ends of the guide frame 1. A cover plate 3 is detachably installed on the top of the guide frame 1. Ear plates 4 are fixedly connected to both sides of the guide frame 1. Pin holes 5 are passed through the ear plates 4, and pin shafts 6 are inserted into the two opposite pin holes 5. A gap is reserved between the upper surface of the cover plate 3 after being buckled on the top of the guide frame 1 and the bottom end of the pin shaft 6, and a wedge block 7 is inserted in the gap. When installing, after the cover plate 3 is buckled on the top of the guide frame 1, the wedge block 7 is inserted into the gap and struck with a hammer so that the cover plate 3 and the guide frame 1 are pressed and fixed. When disassembling, the cover plate 3 can be quickly removed by knocking off the wedge block 7, which is simple and convenient.

[0031] A fixing assembly 8 is installed on the outside of the guide frame 1 for fixing the guide frame 1 on an external device.

[0032] Specifically, the fixing assembly 8 includes a positioning base 81 and a movable support 82 . The positioning base 81 and the movable support 82 are arranged opposite to each other to form a clamp structure to tighten and fix the guide frame 1 , and the positioning base 81 is welded to the outer wall of the external device.

[0033] Specifically, a slide groove 83 is provided on the positioning base 81, and a slider 84 is integrally provided on the movable support 82, and the slider 84 slides inside the slide groove 83. An adjusting bolt 85 passes through and is threadedly connected to the outer side of the movable support 82. A threaded hole matching the adjusting bolt 85 is provided on the positioning base 81. The position of the movable support 82 relative to the positioning base 81 is adjusted, and the guide frame 1 is tightened and fixed on the side to adjust the two U-shaped grooves 2 to be centered to prevent the problem of abnormal wear of the inner wall of the guide groove due to poor alignment.

[0034] Specifically, a clamping block 86 is integrally provided on the inner sides of the top ends of the positioning base 81 and the movable support 82 , and a clamping slot 9 matching the clamping block 86 is provided on both sides of the guide frame 1 .

[0035] Specifically, a key slot 10 is provided at the bottom of the guide frame 1 , and the width of the key slot 10 is greater than the width of the positioning base 81 and the movable support 82 to eliminate the influence of thermal expansion.

[0036] Specifically, the distance from the slot 9 to the key slot 10 is equal to the distance from the block 86 to the upper surface of the bottom horizontal plate of the positioning base 81 and the movable support 82. During installation, the block 86 matches the slot 9. In order to improve the installation strength of the guide frame 1, holes can be selectively punched on the positioning base 81 and the movable support 82, and screws can be installed inside them to strengthen the connection. When a fault occurs, there is no need to remove the entire guide frame 1. It is only necessary to open the cover 3 on the top of the U-shaped slot 2. During daily inspection, the wear of the inner wall of the U-shaped slot 2 can also be easily observed, which is quick and convenient.

[0037] Specifically, positioning notches 11 are provided on both sides of the cover plate 3 , and the positioning notches 11 match the outer diameter of the ear plate 4 , and the cover plate 3 is snap-fitted to the ear plate 4 through the positioning notches 11 .

[0038] Specifically, a handle is welded on the cover plate 3. Since the temperature of the transferred material is relatively high, the heat will be conducted to the cover plate 3. The cover plate 3 can be easily removed through the heat-insulating handle.

[0039] Specifically, a first arc groove 12 and a second arc groove 13 are respectively provided at the end of the U-shaped groove 2 of the guide frame 1 and the bottom of one end of the cover plate 3, and the first arc groove 12 and the second arc groove 13 form a trumpet-shaped expansion when the guide frame 1 and the cover plate 3 are buckled together. A trumpet-shaped anti-wear pipe can be inserted into the trumpet-shaped expansion, which is convenient for guiding materials and prolongs the service life of the device.

[0040] Specifically, a spacing space is reserved between the two sets of guide frames 1 after installation to facilitate observation and heat dissipation.

[0041] When the flying shear duct structure provided by the present invention is in use, the two sets of guide frames 1 are connected end to end, and the fixing components 8 are used to coaxially install them on the side wall of the external equipment, the position of the movable support 82 relative to the positioning base 81 is adjusted, and the guide frame 1 is tightened and fixed on the side to adjust the two U-shaped grooves 2 to be centered, so that the two U-shaped grooves 2 are accurately docked to prevent the problem of abnormal wear of the inner wall of the guide groove caused by poor alignment, and after the cover plate 3 is buckled on the top of the guide frame 1, a wedge block 7 is inserted into the gap and knocked with a hammer so that the cover plate 3 and the guide frame 1 are pressed and fixed. During operation, when the red steel billet after the rolling line flying shear is guided and transported, the red steel billet enters from the anti-wear pipe arranged in the trumpet-shaped expansion mouth and is discharged from the other end. When maintenance or inspection is required, the cover plate 3 can be quickly removed by knocking off the wedge block 7, which is convenient for observing the wear of the inner wall of the U-shaped groove 2.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
