Description

Technical Field

[0001] This application relates to the field of cable winding and unwinding technology, and in particular to a cable winding and unwinding device for rapid winding and unwinding. Background Technology

[0002] Currently, cable winding and unwinding technology is widely used in power, communication, stage equipment and other fields. As the industry's requirements for construction efficiency and safety continue to increase, the requirements for the ease of operation and speed of cable winding and unwinding are also getting higher and higher.

[0003] Existing cable winding and unwinding methods mainly rely on manual reels or electric winding machines. Manual reels involve manually rotating the reel to wind and unwind cables, but this method is inefficient and labor-intensive. Electric winding machines, on the other hand, use a motor to drive the reel to rotate. While this method offers fast winding and unwinding speeds, it is bulky, heavy, and inconvenient to carry, making it unsuitable for small construction sites.

[0004] Therefore, this application provides a cable retraction and deployment device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a cable rapid winding and unwinding device, which overcomes the deficiencies of existing technologies and aims to solve the problems of existing cable winding and unwinding methods, which mainly rely on manual reels or electric winding machines. Manual reels achieve cable winding and unwinding by manually rotating the reel, but this is inefficient and labor-intensive. Electric winding machines drive the reel to rotate via a motor, which, although fast, is bulky, heavy, inconvenient to carry, and unsuitable for small construction sites.

[0006] To achieve the above objectives, this application provides the following technical solution: a cable quick-release device, comprising two sets of brackets, with a cable reel rotatably connected between the two sets of brackets. A cable fixing seat is fixedly installed on the outer surface of the cable reel. An outer cover is fixedly installed on one side of one set of brackets, and a crank is rotatably connected to one side of the outer cover. A transmission mechanism is connected between the crank and one set of cable reels. The transmission mechanism includes a driving bevel gear, which is fixedly installed at one end of the crank. A reducer is fixedly installed inside the outer cover. A driven bevel gear is fixedly installed on the input shaft of the reducer, and the driven bevel gear meshes with the driving bevel gear. A coupling is connected between the output shaft of the reducer and one end of the cable reel. A guide mechanism is provided at the bottom of the two sets of brackets.

[0007] By adopting the above technical solution, the user cranks the handle to drive the active bevel gear to rotate. The active bevel gear meshes with the driven bevel gear to drive the winding shaft to rotate. The reducer provides a speed reduction and force increase effect, reducing the intensity of operation. At the same time, it works with the guide mechanism to guide the wire, so that the cable can be quickly and evenly wound and unwound to the cable fixing seat. This device has a simple structure. Through the linkage of the handle and the transmission mechanism, it combines the flexibility of manual operation with the efficiency of mechanical transmission. It overcomes the problems of low efficiency and high labor intensity of pure manual winding reels, and avoids the disadvantages of electric winding machines being large and inconvenient to carry. Moreover, this device has a simple structure and low cost, making it more suitable for small construction sites.

[0008] As a preferred technical solution of this application, a power box is fixedly installed between the two sets of brackets, located diagonally below the cable fixing seat. The power box is equipped with a guide mechanism, which includes a reciprocating motor and a rotating seat. Both the reciprocating motor and the rotating seat are fixedly installed inside the power box. A screw is fixedly installed between the output end of the reciprocating motor and the rotating seat. A movable seat is threadedly connected to the outer surface of the screw. A connecting rod is fixedly installed at the top of the movable seat. A C-shaped seat is fixedly installed at the top of the connecting rod. Two sets of guide wheels are installed on the top of the C-shaped seat. A wire-passing hole is formed between the two sets of guide wheels. A sliding groove matching the connecting rod is opened on the top of the power box.

[0009] By adopting the above technical solution, one end of the cable is passed through the cable threading hole, and the reciprocating motor is started while the crank is turned. The reciprocating motor drives the screw to rotate, which in turn drives the moving seat to move back and forth along the outer surface of the screw. This causes the two sets of guide wheels to move the cable clamped in the middle synchronously, thereby guiding the cable. The guiding mechanism improves the efficiency of cable winding and unwinding, while avoiding tangling and mess, and improving the neatness of cable winding and unwinding.

[0010] As a preferred technical solution of this application, a rotating shaft is fixedly installed on both sides of the guide wheel, and the guide wheel is rotatably connected to the top of the C-shaped seat through the rotating shaft.

[0011] By adopting the above technical solution, the guide wheels are rotated and connected to the top of the C-shaped seat through the rotating shafts on both sides of the guide wheels. This allows the two sets of guide wheels to guide the cable while rotating and contacting it, thereby reducing wear on the outer surface of the cable and improving the protection effect during the cable winding and unwinding process.

[0012] As a preferred technical solution of this application, a guide block is fixedly installed at the bottom of the movable seat, and a guide groove is opened at the bottom of the power box, with the guide block slidably connected to the inside of the guide groove.

[0013] By adopting the above technical solution, the guide block moves along the sliding end of the guide groove while the moving seat moves back and forth, which improves the guiding and supporting effect of the moving seat during the movement process.

[0014] As a preferred embodiment of this application, bearings are installed at the connection points between the two sets of winding spools and the adjacent brackets.

[0015] By adopting the above technical solution, the frictional resistance of the winding shaft during rotation is reduced by using bearings, thereby improving the rotational stability of the winding shaft.

[0016] As a preferred technical solution of this application, two sets of limiting blocks are fixedly installed on the outer surface of the screw, and the two sets of limiting blocks are far apart.

[0017] By adopting the above technical solution, the movement range of the movable seat on the screw is limited by two sets of limit blocks, preventing the movable seat from leaving the preset path on the screw and improving the reliability of the guiding mechanism.

[0018] As a preferred technical solution of this application, a rotating sleeve is fixedly installed on the top of the crank handle.

[0019] By adopting the above technical solution, the rotating sleeve makes it easier for users to hold and crank the handle, improving the comfort and practicality of operation.

[0020] As a preferred technical solution of this application, the reducer adopts a planetary gear reducer with a reduction ratio of 10:1.

[0021] By adopting the above technical solution, and using a planetary gear reducer with a reduction ratio of 10:1, not only is the stability of the transmission and torque output improved, but users can also reduce effort when cranking the handle, thereby improving the speed and efficiency of cable winding and unwinding.

[0022] The beneficial effects of this application are:

[0023] 1. The user cranks the handle to drive the active bevel gear, which meshes with the driven bevel gear to drive the winding shaft. The reducer provides a speed reduction and force increase effect, reducing the intensity of operation. At the same time, it works with the guide mechanism to guide the wire, so that the cable can be quickly and evenly wound and unwound to the cable holder. This device has a simple structure. Through the linkage of the handle and the transmission mechanism, it combines the flexibility of manual operation with the efficiency of mechanical transmission. It overcomes the problems of low efficiency and high labor intensity of pure manual winding reels, and avoids the disadvantages of electric winding machines being large and inconvenient. Moreover, this device has a simple structure and low cost, making it more suitable for small construction sites.

[0024] 2. By passing one end of the cable through the cable threading hole and turning the crank to start the reciprocating motor, the reciprocating motor drives the screw to rotate, which in turn drives the moving seat to move back and forth along the outer surface of the screw. This causes the two sets of guide wheels to move the cable clamped in the middle synchronously, thus guiding the cable. The guiding mechanism improves the efficiency of cable winding and unwinding, while avoiding tangling and mess, and improving the neatness of cable winding and unwinding. Attached Figure Description

[0031] Reference Figure 1-4A cable reel-in / deel-out device includes two sets of brackets 1, with a cable reel 2 rotatably connected between the two sets of brackets 1.

An outer cover 4 is fixedly installed on one side of one set of brackets 1, and a crank 8 is rotatably connected to one side of the outer cover 4. A transmission mechanism 5 is connected between the crank 8 and the set of cable reel 2. The transmission mechanism 5 includes a driving bevel gear 501, which is fixedly installed at one end of the crank 8. A reducer 502 is fixedly installed inside the outer cover 4. A driven bevel gear 503 is fixedly installed on the input shaft of the reducer 502. The driven bevel gear 503 meshes with the driving bevel gear 501. A coupling 504 is connected between the output shaft of the reducer 502 and one end of the cable reel 2. A guide mechanism 7 is provided at the bottom of the two sets of brackets 1.

[0032] The user cranks the handle 8 to drive the active bevel gear 501 to rotate. The active bevel gear 501 meshes with the driven bevel gear 503 to drive the winding shaft 2 to rotate. The reducer 502 provides a speed reduction and force increase effect, reducing the intensity of operation. At the same time, it works with the guide mechanism 7 to guide the wire, so that the cable can be quickly and evenly wound and unwound to the cable fixing seat 3. This device has a simple structure. Through the linkage of the handle 8 and the transmission mechanism 5, it combines the flexibility of manual operation with the efficiency of mechanical transmission. It overcomes the problems of low efficiency and high labor intensity of pure manual winding reels, and avoids the disadvantages of electric winding machines being large and inconvenient. Moreover, this device has a simple structure and low cost, making it more suitable for small construction sites.

[0033] Reference Figure 1-3 A power box 6 is fixedly installed between the two sets of brackets 1, diagonally below the cable fixing base 3. A guide mechanism 7 is installed inside the power box 6. The guide mechanism 7 includes a reciprocating motor 701 and a rotating base 702, both fixedly installed inside the power box 6. A screw 703 is fixedly installed between the output end of the reciprocating motor 701 and the rotating base 702. A movable base 704 is threaded onto the outer surface of the screw 703. A connecting rod 705 is fixedly installed at the top of the movable base 704. The top of the connecting rod 705 is fixed... A C-shaped seat 706 is installed, and two sets of guide wheels 707 are installed on the top of the C-shaped seat 706. A wire hole 708 is formed between the two sets of guide wheels 707. A sliding groove 709 matching the connecting rod 705 is opened on the top of the power box 6. A rotating shaft 13 is fixedly installed on both sides of the guide wheel 707, and the guide wheel 707 is rotatably connected to the top of the C-shaped seat 706 through the rotating shaft 13. A guide block 9 is fixedly installed at the bottom of the movable seat 704, and a guide groove 10 is opened at the bottom of the power box 6. The guide block 9 is slidably connected to the inside of the guide groove 10.

[0034] By passing one end of the cable through the threading hole 708, the reciprocating motor 701 is started while the crank handle 8 is turned. The reciprocating motor 701 drives the screw 703 to rotate, which in turn drives the moving seat 704 to move back and forth along the outer surface of the screw 703. This causes the two sets of guide wheels 707 to move the cable clamped in the middle synchronously, thus guiding the cable. The guide mechanism 7 improves the efficiency of cable winding and unwinding, and avoids tangling and mess, improving the neatness of cable winding and unwinding. The rotating shafts 13 on both sides of the guide wheels 707 connect the guide wheels 707 to the top of the C-shaped seat 706, so that the two sets of guide wheels 707 guide the cable and rotate in contact with it, thereby reducing wear on the outer surface of the cable and improving the protection effect during cable winding and unwinding. The reciprocating movement of the moving seat 704 is linked to the movement of the guide block 9 along the sliding end of the guide groove 10, which improves the guiding and supporting effect of the moving seat 704 during movement.

[0035] Reference Figure 1-3 Bearings 11 are installed at the connection between the two sets of winding spools 2 and the adjacent brackets 1; a rotating sleeve 14 is fixedly installed on the top of the crank handle 8; the bearings 11 reduce the frictional resistance of the winding spool 2 during rotation and improve the stability of the winding spool 2 rotation; the rotating sleeve 14 makes it easier for the user to hold and crank the crank handle 8, improving the comfort and practicality of operation.

[0036] Reference Figure 2-4 Two sets of limiting blocks 12 are fixedly installed on the outer surface of the screw 703, and the two sets of limiting blocks 12 are far apart; the reducer 502 adopts a planetary gear reducer with a reduction ratio of 10:1; the two sets of limiting blocks 12 limit the movement range of the moving seat 704 on the screw 703, prevent the moving seat 704 from leaving the preset path on the screw 703, and improve the reliability of the guide mechanism 7; by adopting a planetary gear reducer with a reduction ratio of 10:1 in the reducer 502, not only is the stability of the transmission and torque output improved, but the user can also make it easier to crank the handle 8, thereby improving the speed and efficiency of cable winding and unwinding.

[0037] Working principle: By passing one end of the cable through the cable hole 708, the reciprocating motor 701 is started by turning the crank handle 8. The reciprocating motor 701 drives the screw 703 to rotate, which in turn drives the moving seat 704 to move back and forth along the outer surface of the screw 703. This causes the two sets of guide wheels 707 to move the cable clamped in the middle synchronously. The user turns the crank handle 8 to drive the active bevel gear 501 to rotate. The active bevel gear 501 meshes with the driven bevel gear 503 to drive the winding shaft 2 to rotate. The reducer 502 provides a speed reduction and force increase effect, reducing the operating intensity. At the same time, it works with the guide mechanism 7 to guide the wire, so that the cable can be quickly and evenly wound and unwound in the cable fixing seat 3.

[0038] Among them, the guide wheel 707 is rotatably connected to the top of the C-shaped seat 706 by the rotating shaft 13 on both sides of the guide wheel 707, so that the two sets of guide wheels 707 guide the cable and rotate in contact with it at the same time. The guide block 9 moves along the sliding end of the guide groove 10 while the moving seat 704 moves back and forth.

[0039] Meanwhile, the movement range of the movable seat 704 on the screw 703 is limited by two sets of limiting blocks 12; the frictional resistance of the winding shaft 2 during rotation is reduced by the bearing 11;

[0040] In addition, the rotating sleeve 14 makes it easier for the user to hold and crank the handle 8; the planetary gear reducer 502 with a reduction ratio of 10:1 not only improves the stability of the transmission and the torque output, but also makes it easier for the user to crank the handle 8.
