[0003] Existing unwinding devices cannot limit the movement of coiled wire ropes at different heights; at the same time, existing unwinding devices adjust the unwinding speed by changing the motor speed, and frequent acceleration / deceleration will cause current fluctuations, increased copper and iron losses, and motor overheating may damage the insulation material, shorten the motor life, or even trigger overheat protection shutdown; therefore, we need to propose a coiled wire rope unwinding device. Utility Model Content

[0004] The purpose of this invention is to provide a coiled wire rope unwinding device. By adjusting the components, the upper pressure plate moves up and down on the outer arc surface of the sleeve column, thereby limiting the wire rope coils of different heights. Then, by adjusting the speed adjustment components, the contact area and force between the speed adjustment column and the placement base are adjusted, thereby achieving the effect of slowing down the rotation speed of the placement base through friction. This avoids the need for frequent acceleration and deceleration of the motor, which could lead to motor damage or shutdown, thus solving the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a device for unwinding coiled steel wire rope, such as... Figure 1-5 As shown, the device includes a base 1 and a placement chassis 3. A driven gear 2 for rotating the placement chassis 3 is mounted on the upper surface of the base 1. A driving gear 11 for rotating the driven gear 2 is mounted above the base 1. A motor 12 for rotating the driving gear 11 is mounted on the upper surface of the base 1. A support plate 10 for auxiliary support of the driving gear 11 is mounted on the side of the base 1. The motor 12 drives the driving gear 11 to rotate, and the support plate 10 provides auxiliary support to the driving gear 11, ensuring the stability of the driving gear 11 during rotation. The driven gear 2 is rotated by the meshing of the outer arc surface teeth, and the driven gear 2 is rotated on the upper surface of the base 1, thereby driving the placement chassis 3 to rotate. The motor 12 in this application is not within the scope of the technology protected by this application and can be purchased and used directly in the market or online. The placement chassis 3 is made of high-quality carbon structural steel, which has high strength and high wear resistance. Through the cooperation of the driven gear 2 and the placement chassis 3, the technical effect of driving the placement chassis 3 to rotate and unload the cable is achieved, which solves the technical problem of excessive pressure when the motor 12 directly drives the placement chassis 3 to rotate.

[0026] Preferably, the upper surface of the placement base 3 is provided with a limiting post 4 and a connecting post 9 for connecting the wire rope coil. The wire rope coil is placed on the upper surface of the placement base 3 through the connecting post 9, and the limiting post 4 is inserted into the wire rope coil to ensure that the wire rope coil rotates and unwinds with the placement base 3. The upper surface of the base 1 is provided with a mechanism for pulling and adjusting the tension of the unwound portion of the wire rope coil. The pulling and tension adjustment mechanism is a technology well known to those skilled in the art and is not within the scope of the technology protected by this application. Therefore, it will not be described in detail in the specification.

[0027] Specifically, an upper pressure plate 8 is provided above the base 3 to limit the movement of the wire rope coil. An adjustment assembly for adjusting the height of the upper pressure plate 8 to limit the movement of the wire rope coil is provided on the upper surface of the base 1. The adjustment assembly includes a mounting frame 7, a moving block 15, and a lead screw 16. The moving block 15 is located on the outer arc surface of the upper pressure plate 8. A through hole 14 is provided on the upper surface of the moving block 15 for fitting onto the outer arc surface of the connecting post 9. A moving groove 17 is provided inside the mounting frame 7 to limit the movement of the moving block 15. The lead screw 16 is rotatably positioned inside the moving groove 17. The moving block 15 is threaded onto the outer arc surface of the lead screw 16. Rotating the lead screw 16 drives the moving block 15 up and down via the thread. The moving block 15 is designed as a protrusion. The moving block 15 drives the upper pressure plate 8 up and down to limit the movement of wire rope coils at different heights. Through the cooperation of the moving block 15 and the moving groove 17, the technical effect of ensuring the moving block 15 moves up and down along the moving groove 17 is achieved, solving the technical problem of rotation during the movement of the moving block 15.

[0028] Furthermore, a first mounting plate 6 is provided on the lower surface of the mounting frame 7, and a second mounting plate 20 for driving the mounting frame 7 to rotate is provided on the lower surface of the first mounting plate 6. A limiting rod 22 for limiting the second mounting plate 20 is provided on the outer side of the second mounting plate 20. A mounting groove 19 for the second mounting plate 20 to rotate is provided on the upper surface of the base 1, and a limiting groove 18 for limiting the limiting rod 22 is provided on the upper surface of the base 1. The limiting groove 18 and the mounting groove 19 are connected. The mounting frame 7 is connected by the first mounting plate 6 and the second mounting plate. The column 20 and the bottom column are rotatably mounted on the upper surface of the base 1. The side of the first mounting plate 6 is provided with an operating rod 21 to facilitate the rotation of the first mounting plate 6 and the second mounting plate 20. The limiting groove 18 and the mounting groove 19 are provided to ensure that the mounting frame 7 can rotate, thereby facilitating the loading and unloading of the wire rope coil placed on the upper surface of the base 3. Through the cooperation of the limiting rod 22 and the limiting groove 18, the technical effect of driving the mounting frame 7 to rotate away from or near the sleeve column 9 is achieved, solving the technical problem of not being able to align the sleeve column 9 and the through hole 14.

[0029] Furthermore, the upper surface of the base 1 is provided with a speed regulating component for controlling the rotation of the chassis 3 through friction. The speed regulating component includes a mounting base 5, a speed regulating column 13, and a moving column 23. The speed regulating column 13 is made of high-carbon, high-chromium bearing steel, which has a stable coefficient of friction, high speed regulation accuracy, and good heat resistance, maintaining hardness and dimensional stability even under long-term frictional heat generation. The mounting base 5 is located on the upper surface of the base 1, and the speed regulating column 13 is slidably disposed inside the mounting base 5. The speed regulating column 13 is rotatably connected to the moving column 23 via a connecting column. The moving column 23 is threadedly connected to the mounting base 5. When the moving column 23 rotates, it is pushed towards the mounting base 5 by the action of the thread. The seat 5 moves inside or outside, thereby moving the speed regulating column 13, which in turn moves the speed regulating column 13 closer to or away from the placement chassis 3. When the speed regulating column 13 contacts the placement chassis 3, it continues to move closer to the placement chassis 3. At this time, the contact force between the speed regulating column 13 and the placement chassis 3 will increase, thereby increasing the friction between the placement chassis 3 and the speed regulating column 13. Through the cooperation of the placement chassis 3 and the speed regulating column 13, the technical effect of adjusting the speed of the placement chassis 3 by the friction between the speed regulating column 13 and the placement chassis 3 is achieved, which solves the technical problem that frequent adjustment of the speed of the motor 12 will easily damage the motor 12.

[0030] It is worth noting that the speed regulating column 13 is located on the side of the moving column 23 closest to the placement chassis 3, and the speed regulating column 13 is in contact with the placement chassis 3. An extension column 24 for driving the moving column 23 to rotate is provided on the side of the moving column 23 away from the speed regulating column 13. A locking column 25 for limiting the speed regulating column 13 is provided on the outer arc surface, and a locking groove 26 for limiting the locking column 25 is provided on the outer arc surface of the mounting base 5. The extension column 24 is provided to facilitate the rotation of the moving column 23, and the speed regulating column 13 and the moving column 23 are rotatably connected by a connecting column. Through the cooperation of the locking column 25 and the locking groove 26, the technical effect of the moving column 23 not rotating when driving the speed regulating column 13 to move is achieved. This solves the technical problem that when the speed regulating column 13 contacts the placement chassis 3, it cannot rotate under the action of friction, thus making it impossible to adjust the contact force between the speed regulating column 13 and the placement chassis 3.
