Description

Technical Field

[0001] This utility model relates to the field of wire reeling and releasing technology, and in particular to a wire reeling and releasing device for rapid reeling and releasing. Background Technology

[0002] Wire rope coiling refers to winding wire rope on a drum or plate in a certain way for easy storage, transportation and use. Wire rope is widely used in construction, mining, shipbuilding, crane and other fields. It is usually used to lift, tighten or support heavy objects. It generally uses neat cross winding to ensure that the wire rope is evenly distributed on the drum and avoid slack or cross winding.

[0003] Previously, when replacing the wire rope, the rope was moved outwards from the steel ring, one loop at a time. However, some areas still had stress that could not be removed, resulting in numerous knots. This process also posed certain risks and required more manpower, leading to a waste of human resources and time. Therefore, it is necessary to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid wire release and release device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid winding and unwinding device includes a base with three support frames horizontally fixedly connected to the top of the base. The three support frames are evenly distributed in a ring. A support seat is rotatably connected to the top of each of the three support frames. A rotating mechanism for rotating the support seat is provided on the top of the base. A braking mechanism is provided inside each of the three support frames. A support column is fixedly connected to the center of the top of the support seat. Three fixing boxes are horizontally fixedly connected to the surface of the support seat. One end of each fixing box is fixedly connected to the surface of the support column. A slider is horizontally slidably connected inside each of the three support columns. A sliding mechanism for sliding the three sliders is provided inside each of the three fixing boxes. The multiple sliders allow for adjustment of the positions of the three sliders according to the size of the winding roller before placement, ensuring the winding roller is more centered during placement and improving stability during rotation. Furthermore, the multiple pedals and brake plates facilitate stopping the support seat, thereby enhancing the safety of the device.

[0007] Preferably, the rotating mechanism includes a ball bearing, which is located at the center of the top of the base and is fixedly connected to the top of three support frames. A fixed shaft is vertically fixedly connected to the center of the bottom of the support base, and the fixed shaft is rotatably sleeved inside the center of the ball bearing. Three fixed columns are vertically fixedly connected to the top of the base, and the three fixed columns are respectively located between the three support frames. Rollers are rotatably connected to the top of each of the three fixed columns, and the three rollers roll at the bottom of the support base to restrict the rotation of the support base on the base. This allows the take-up roller to rotate simultaneously, facilitating the pulling and releasing of the wire rope on the take-up roller.

[0008] Furthermore, the braking mechanism includes two connecting rods, which are rotatably connected to symmetrical sides of the support frame surface. Both connecting rods are L-shaped, and a rotating shaft is fixedly connected between them. The rotating shaft is rotatably sleeved inside the support frame. One end of each connecting rod is fixedly connected to the same pedal, and the other end is fixedly connected to the same brake plate. The brake plate is located at the bottom of the support base. A connection port is provided at the top of the support frame, and a tension spring is provided inside the connection port. The top end of the tension spring is fixedly connected to the bottom of the brake plate, and the bottom end of the tension spring is fixedly connected to the bottom of the support frame. This restricts the rotation of the multiple connecting rods, so that the brake plate can slide upward by pressing the pedal, and then contact the bottom of the support base to produce a braking effect.

[0009] Preferably, the sliding mechanism includes a lead screw, the surface of the fixed box has multiple scale lines, the top of the slider has a marking line, the lead screw is rotatably connected to the inside of the fixed box, the lead screw is horizontally arranged, two of the lead screws are respectively rotatably sleeved at both ends inside the fixed box, the lead screw is rotatably sleeved inside the slider, the slider cooperates with the lead screw, and a knob is fixedly connected to one end of the lead screw for sliding each slider individually, so that when placing the take-up roller, according to the marking line on the slider, the take-up roller is placed more centrally on the surface of the support.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, the three knobs can be manually turned, which will drive the three lead screws to rotate and adjust the position of the three sliders. This allows the sliders to be moved to the appropriate position according to the size of the take-up roller to be placed. Then, the take-up roller is placed on the support base, supported by the support column and three fixing boxes. The bottom of the take-up roller is aligned with the marked line on the surface of the adjusted slider, so that the take-up roller is kept in a more centered position on the support base. Then, manually rotating the support base and the take-up roller can improve the stability of the take-up roller.

[0012] 2. When it is necessary to stop the rotation of the support base and the take-up roller, either pedal can be pressed. Under the connection of the two connecting rods, the tension spring will be stretched, and the brake plate will slide upward to contact the bottom of the support base, thereby braking the support base and stopping its rotation, thus improving the safety of use.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4A rapid winding and unwinding device includes a base 1. Three support frames 11 are horizontally fixedly connected to the top of the base 1. The three support frames 11 are evenly distributed in a ring. A support seat 2 is rotatably connected to the top of the three support frames 11. A rotating mechanism for rotating the support seat 2 is provided on the top of the base 1. A braking mechanism is provided inside each of the three support frames 11. A support column 22 is fixedly connected to the center of the top of the support seat 2. Three fixing boxes 23 are horizontally fixedly connected to the surface of the support seat 2. One end of each fixing box 23 is fixedly connected to the surface of the support column 22. A slider 5 is horizontally slidably connected inside each of the three support columns 22. A sliding mechanism for sliding the three sliders 5 is provided inside each of the three fixing boxes 23. By setting multiple sliders 5, the position of the three sliders 5 can be adjusted according to the size of the take-up roller 3 before it is placed. This keeps the take-up roller 3 more centered when it is placed, thus improving the stability of the take-up roller 3 during rotation. At the same time, with the setting of multiple pedals 4 and brake plates 43, it is easy to stop the support seat 2, thereby improving the safety of the device.

[0020] In this utility model, the rotating mechanism includes a ball bearing 15, which is located at the top center of the base 1. The ball bearing 15 is fixedly connected to the top of three support frames 11. A fixed shaft 21 is vertically fixedly connected to the bottom center of the support seat 2. The fixed shaft 21 is rotatably sleeved inside the center of the ball bearing 15. Three fixed columns 13 are vertically fixedly connected to the top of the base 1. The three fixed columns 13 are respectively located between the three support frames 11. Rollers 14 are rotatably connected to the top of each of the three fixed columns 13. The three rollers 14 roll on the bottom of the support seat 2 to restrict the rotation of the support seat 2 on the base 1, so that the winding roller 3 can be rotated at the same time, which facilitates the pulling and releasing of the wire rope 31 on the winding roller 3.

[0021] In this utility model, the braking mechanism includes two connecting rods 41, which are rotatably connected to symmetrical sides of the surface of the support frame 11. Both connecting rods 41 are L-shaped. A rotating shaft 42 is fixedly connected between the two connecting rods 41. The rotating shaft 42 is rotatably sleeved inside the support frame 11. One end of the two connecting rods 41 is fixedly connected to the same pedal 4, and the other end of the two connecting rods 41 is fixedly connected to the same brake plate 43. The brake plate 43 is located at the bottom of the support base 2. A connection port 12 is opened at the top of the support frame 11. A tension spring 44 is installed inside the connection port 12. The top end of the tension spring 44 is fixedly connected to the bottom of the brake plate 43, and the bottom end of the tension spring 44 is fixedly connected to the bottom of the support frame 11. This restricts the rotation of the multiple connecting rods 41. By pressing the pedal 4, the brake plate 43 can slide upward and contact the bottom of the support base 2, thereby producing a braking effect.

[0022] In this utility model, the sliding mechanism includes a lead screw 52, ​​a plurality of scale lines 24 are provided on the surface of the fixed box 23, and a marking line 51 is provided on the top of the slider 5. The lead screw 52 is rotatably connected to the inside of the fixed box 23. The lead screw 52 is horizontally arranged. Two lead screws 52 are respectively rotatably sleeved at both ends inside the fixed box 23. The lead screw 52 is rotatably sleeved inside the slider 5. The slider 5 cooperates with the lead screw 52. A knob 53 is fixedly connected to one end of the lead screw 52 for sliding each slider 5 separately. Thus, when placing the take-up roller 3, according to the marking line 51 on the slider 5, the take-up roller 3 is placed more centrally on the surface of the support base 2.

[0023] Working Principle: In actual use, the multiple sliders 5 allow for easy adjustment of their positions before placing the take-up roller 3, based on its size. This ensures the take-up roller 3 remains centered during placement, improving its stability during rotation. The multiple pedals 4 and brake plates 43 facilitate stopping the support base 2, enhancing safety. During use, three knobs 53 are manually rotated, causing three lead screws 52 to rotate and adjusting the positions of the three sliders 5. This allows the sliders 5 to be moved to the appropriate position according to the size of the take-up roller 3 to be placed. The take-up roller 3 is then placed on the support base 2, secured by the support column 22 and three fixed... The fixed box 23 supports the take-up roller 3 and aligns the bottom of the take-up roller 3 with the marking line 51 on the surface of the adjustable slider 5, so that the take-up roller 3 can be kept in a more central position on the support base 2. Then, manually rotating the support base 2 and the take-up roller 3 can improve the stability of the take-up roller 3. The three rollers 14 set on the top of the base 1 also improve the support effect of the support base 2. When it is necessary to stop the rotation of the support base 2 and the take-up roller 3, either pedal 4 can be pressed. The connection between the two connecting rods 41 will stretch the tension spring 44, and at the same time, the brake plate 43 will slide upward and contact the bottom of the support base 2, thereby braking the support base 2 and stopping its rotation, thus improving the safety of use.
