[0002] Metal rod coils, an indispensable material in the manufacturing and industrial sectors, are widely used in electronic equipment, building structures, and communications facilities. With the advancement of manufacturing and the development of new energy sources, the demand for metal rod coils has increased dramatically. However, most companies producing metal rod coils still rely on manual labor for warehousing operations. This has not only led to a surge in labor demand, but also faced heavy workloads for workers, making warehousing tasks difficult to complete efficiently. Furthermore, due to the large size and weight of metal rod coils, which involve working at height, there are high safety risks during operation, including the risk of personal injury or product damage. To improve this situation, an internally tensioned multi-degree-of-freedom fixture system was designed that can work in conjunction with construction machinery to achieve automated warehousing of metal rod coils, thereby reducing potential risks during manual handling and improving the safety and efficiency of operations.

[0003] However, in the application process of existing clamps, due to the fragility of the clamps and the lack of real-time manual monitoring in the automated operation environment, the metal rod coils often damage the clamps, resulting in a decline in the quality of the production process and an inability to guarantee the continuity of the production process.

[0025] See also Figure 1 , Figure 1 This is a schematic structural diagram of the internal tension clamping tool of the present utility model.

[0026] like Figure 1 As shown, in one embodiment of the present application, an internal tension clamping tool includes an internal tension clamp and a clamp protection device. The internal tension clamp includes an expansion mechanism 4, a transmission mechanism 5, and a hydraulic mechanism 6. The expansion mechanism 4 is connected to the hydraulic mechanism 6 via the transmission mechanism 5. The clamp protection device includes at least one expansion plate scriber 2 and a clamp limiter 3. The expansion plate scriber 2 is detachably connected to the outside of the expansion mechanism 4. The clamp limiter 3 is disposed between the expansion mechanism 4 and the hydraulic mechanism 6. During use, the hydraulic mechanism 6 is extended and retracted to link the transmission mechanism 5 to control the expansion mechanism 4 to expand or retract, so that the internal tension clamp extends into a cylindrical object, such as a metal rod coil, to clamp and release. Among them, the expansion plate slice 2 arranged in the expansion mechanism 4 can form a protective barrier between the internal tensioning clamp and the clamped metal rod roll during the actual application of the internal tensioning clamping tool, preventing the metal rod roll from damaging the internal tensioning clamp; the clamp limit device 3 can ensure that the internal tensioning clamp will not extend too deeply into the metal rod roll during actual application, avoiding the internal tensioning clamp from extending too deeply into the ground and causing hard contact damage.

[0027] In one embodiment of the present application, the transmission mechanism 5 includes at least two transmission rods, and the transmission rods are connected by screws. The expansion mechanism 4 is connected to the hydraulic mechanism 6 through the transmission mechanism 5, and the connection method is screw connection.

[0028] In one embodiment of the present application, the above-mentioned expansion plate slice 2 is detachably connected to the outer side of the expansion mechanism 4, and the detachable connection includes a screw connection or a slide rail connection, wherein the outer side of the expansion mechanism 4 refers to the side that contacts the clamped object after the expansion mechanism 4 is expanded.

[0029] In one embodiment of the present application, the expansion mechanism 4 includes at least two expansion arms, which are the portions facing outward from the expansion mechanism 4 and in contact with the clamped object. In one embodiment of the present application, the expansion mechanism 4 includes two expansion arms, which are symmetrically arranged on both sides of the central axis of the expansion mechanism 4.

[0030] Please combine Figure 2 , Figure 2 This is a schematic diagram of the connecting slide rail structure of the present utility model.

[0031] In one embodiment of the present application, when the detachable connection is a slide rail connection, a connecting slide groove parallel to the central axis of the expansion arm is provided on the outward expansion side of each expansion arm, and a connecting slide rail 7 is provided on the side of the expansion plate scribe 2 connected to the expansion arm. The expansion plate scribe 2 is slidably connected to the connecting slide groove of the expansion arm via the connecting slide rail 7. The above-mentioned connecting slide groove is preferably provided as a through-type connecting slide groove to provide a more flexible sliding connection method.

[0032] In one embodiment of the present application, a slide rail limit block 8 is provided at one end of the connecting slide rail 7 to prevent the expansion plate scriber 2 from sliding through.

[0033] In one embodiment of the present application, when the detachable connection is a screw connection, a screw hole is opened on the outward expansion side of each expansion arm, and the screw hole can be a through type or a non-through type, and the screw hole is opened perpendicular to the central axis of the expansion arm; the expansion plate slice 2 opens a connecting screw hole corresponding to the screw hole of the expansion arm, so as to connect the expansion plate slice 2 and the expansion arm by screws.

[0034] The expansion plate scriber 2 is detachably connected to the outside of the expansion mechanism 4, which facilitates the disassembly and replacement of the worn or damaged expansion plate scriber 2, thereby reducing the maintenance cost and complexity of the internal tension clamping tool.

[0035] In one embodiment of the present application, the expansion plate scribe 2 is an arc-shaped sheet, wherein the convex side of the arc is aligned with the outer side of the expansion mechanism 4, so that the expansion plate scribe 2 can better fit the interior of the cylindrical metal rod coil. In some preferred embodiments, the expansion plate scribe 2 can be manufactured in interchangeable models with different curvatures to accommodate cylindrical clamped objects with different inner diameters.

[0036] In one embodiment of the present application, the expansion plate scriber 2 is made of metal material and has sufficient rigidity to better protect the expansion mechanism 4 , and the connecting slide rail 7 is arranged on the central axis of the expansion plate scriber 2 .

[0037] In one embodiment of the present application, the clamp protection device further includes a scribe flexible surface sheet 1, which is disposed on the outwardly expanding side of the expansion plate scribe 2 and partially or completely covers the outwardly expanding side of the expansion plate scribe 2. The scribe flexible surface sheet 1 is made of rubber or resin and is riveted or bonded to the outwardly expanding side of the expansion plate scribe 2. This not only protects the expansion plate scribe 2 and improves its durability, but also reduces contact damage to the metal rod coil caused by the expansion plate scribe 2. Furthermore, the scribe flexible surface sheet 1 increases the friction between the expansion plate scribe 2 and the interior of the metal rod coil, thereby improving the application effect.

[0038] In one embodiment of the present application, the clamp limiting device 3 includes a limiting plate and a connecting plate, the connecting plate is vertically connected to the limiting plate, the connecting plate is symmetrically arranged between the expansion mechanism 4 and the hydraulic mechanism 6, and the outward extension length of the limiting plate is greater than the axial radius length of the expansion mechanism 4 in the contracted state. Among them, the clamp limiting device 3 is made of metal material, and the connecting plate is connected between the expansion mechanism 4 and the hydraulic mechanism 6 by screws. The clamp limiting device 3 is arranged between the expansion mechanism 4 and the hydraulic mechanism 6. In actual application, it can be ensured that the internal tensioning clamp will not extend too deeply into the metal rod roll, avoiding the internal tensioning clamp from extending too deeply into the ground and causing hard contact damage. The connecting plate of the clamp limiting device 3 is connected between the expansion mechanism 4 and the hydraulic mechanism 6 by screws, which is convenient for disassembly, replacement and adaptation during application, thereby improving the adaptability of the clamp.
