Description

Technical Field

[0001] This invention relates to the field of power grid equipment technology, and in particular to a cable winding and unwinding device and its operating method. Background Technology

[0002] Cable handling refers to the orderly handling, winding, and storage of cables during construction, installation, or routine maintenance. This process is crucial to ensuring cables are not damaged and to prevent tangling. During cable handling, cables of different diameters may encounter unique challenges due to differences in size, weight, flexibility, and other physical properties, such as tangling, bending, or even damage. For example, thinner cables may be excessively bent, tangled, or difficult to place accurately, while thicker cables may be prone to deformation or mechanical damage due to excessive weight or insufficient strength.

[0003] Currently, to prevent cables from tangling, deforming, or being damaged during winding and unwinding due to differences in cable diameter, existing cable winding and unwinding devices typically use guide tubes with different apertures to guide the cable winding and unwinding. However, changing guide tubes for cable guidance is complex, time-consuming, and labor-intensive. Furthermore, multiple guide tubes need to be prepared for different cable diameters, and they are prone to being lost, resulting in low economic efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a cable winding and unwinding device and its operating method, which has a simple structure and its clamping mechanism can be compatible with the clamping and guiding of cables of different diameters.

The clamping mechanism includes a first U-shaped frame, air guide tubes, air bladders, a motor, and an inflation assembly. The first U-shaped frame is fixedly mounted on the mounting frame. Two air guide tubes are rotatably mounted inside the first U-shaped frame, and the two air guide tubes are spaced apart in a vertical direction. Each air guide tube is fitted with an air bladder, which communicates with the air guide tube. The two air bladders are spaced apart in the vertical direction. Each air bladder is provided with a conveying groove, which is arranged circumferentially around the rotation axis of the air bladder.

The drain pipe is fixedly inserted into the bottom of the air collection box, and an air delivery box is fixedly sleeved at the bottom end of the drain pipe. The ends of the two L-shaped tubes away from the air guide pipe are respectively fixedly inserted into the bottom and side surfaces of the air delivery box. A second one-way exhaust valve is provided on the drain pipe.

[0008] As a preferred embodiment of the cable winding and unwinding device, the length of the air collecting box extends along the second direction. The driving component includes a piston plate and an electric push rod. The piston plate is slidably installed inside the air collecting box. The electric push rod is fixedly installed on one side of the air collecting box along the second direction. The driving end of the electric push rod extends into the air collecting box and is fixedly connected to the piston plate. A one-way air inlet valve is provided at the end of the air collecting box away from the electric push rod along the second direction. The drain pipe is connected to the end of the air collecting box away from the electric push rod along the second direction.

[0009] As a preferred embodiment of the cable winding and unwinding device, the inflation assembly further includes a diverter plate, which is fixedly installed inside the air supply box. The diverter plate divides the inner cavity of the air supply box into a first air chamber and a second air chamber.

[0010] As a preferred embodiment of the cable winding and unwinding device, a solenoid valve is provided on one side of the air bladder, which can connect the air inside the air bladder with the outside air.

[0011] As a preferred embodiment of the cable winding and unwinding device, the winding mechanism includes a motor and a take-up roller. The take-up roller is rotatably mounted on the mounting frame, and the motor is fixedly mounted on the bottom of the mounting frame. The drive shaft of the motor passes through the mounting frame and is connected to the take-up roller for transmission. The rotation axis of the take-up roller extends along the vertical direction.

[0012] As a preferred embodiment of the cable winding and unwinding device, the cable winding and unwinding device further includes an adjustment assembly. The adjustment assembly is disposed on the mounting frame and is located between the winding mechanism and the first U-shaped frame along the second direction.

The second U-shaped frame is disposed on the mounting frame, the cylinder is disposed on the top of the second U-shaped frame, and the fixed cylinder is located inside the second U-shaped frame.

[0013] As a preferred embodiment of the cable winding and unwinding device, the adjusting component further includes ball bearings, and a plurality of ball bearings are spaced apart on the inner side wall of the fixed cylinder.

[0014] Secondly, a method for operating a cable winding and unwinding device is provided, comprising the following steps:

[0015] S10. Pass the free end of the cable through the clamping groove formed by the two airbags in the clamping mechanism of the cable winding and unwinding device, and wind the free end of the cable into the winding mechanism.

[0016] S20. Activate the inflation component of the clamping mechanism to inflate the airbag and deform it to clamp the cable.

[0017] S30. Start the winding mechanism to wind up the cable.

[0019] The beneficial effects of this invention are as follows: By using an inflation component to inflate two spaced airbags to accommodate cables of different diameters, the invention effectively guides and limits cable winding operations, reducing issues such as cable deviation and entanglement during winding. It offers high compatibility, ease of operation, and saves time and effort. The airbag inflation and encapsulation effectively improves the fit of cables of different diameters, resulting in a larger contact area and more even clamping force around the cable, preventing deformation or damage caused by excessive local clamping force. The rotating design of the airbags and air ducts effectively reduces frictional loss between the cable and airbags during winding, ensuring the service life of both the cable and airbags. Furthermore, the airbags can be actively rotated by a motor, further reducing wear on both the cable and airbags. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0029] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] like Figures 1 to 5As shown, the cable winding and unwinding device of this embodiment includes a mounting frame 1, a clamping mechanism, and a winding mechanism. The clamping mechanism includes a first U-shaped frame 2, air pipes 3, air bladders 4, a motor 6, and an inflation assembly. The first U-shaped frame 2 is fixedly mounted on the mounting frame 1. Two air pipes 3 are rotatably mounted inside the first U-shaped frame 2, and the two air pipes 3 are spaced apart in a vertical direction (vertical direction is the Z direction shown in the figure). An air bladder 4 is fitted over each air pipe 3, and the air bladder 4 communicates with the air pipe 3. The two air bladders 4 are spaced apart in a vertical direction, and each air bladder 4 is provided with a conveying groove 5. The conveying groove 5 is arranged in a ring around the rotation axis of the air bladder 4, and the bottoms of the two conveying grooves 5 are spaced apart to form clamping grooves for clamping cables. The motor 6 is fixedly installed on one side of the first U-shaped frame 2 along the first direction (the first direction is the X direction in the figure), and the drive shaft of the motor 6 is connected to one end of one of the air guide pipes 3 to drive the air guide pipe 3 connected to the motor 6 to rotate; the inflation assembly is set on the side of the first U-shaped frame 2 away from the motor 6 along the first direction, and the inflation assembly is used to inflate the airbag 4, so that the airbag 4 deforms to form clamping grooves of different sizes to adapt to the clamping of cables of different diameters; the winding mechanism is set on the mounting frame 1, and the winding mechanism is located on one side of the clamping mechanism along the second direction (the second direction is the Y direction in the figure), and the winding mechanism can wind or unwind the cable, wherein the first direction, the second direction and the vertical direction are arranged perpendicularly.

[0033] Understandably, by using an inflation component to inflate two spaced airbags 4 to accommodate cables of different diameters, the cable winding and unwinding operations are effectively guided and limited, reducing issues such as cable deviation and entanglement during the winding and unwinding process. This method offers high compatibility, simple operation, time and labor savings, and high economic benefits. Furthermore, by setting a conveying groove 5 on the airbag 4, the position of the cable on the airbag 4 is effectively limited, improving the positional accuracy of the cable on the airbag 4. Additionally, the groove walls on both sides of the conveying groove 5 along the first direction can be used to enhance the cable's wrapping properties. By inflating the airbag 4 for wrapping and clamping, the fit of cables of different diameters is effectively improved, the contact area of ​​the cable is increased, and the clamping force of the airbag 4 on the periphery of the cable is more balanced, avoiding deformation or damage caused by excessive local clamping force. By rotating the airbag 4 and the air guide tube 3, the friction loss between the cable and the airbag 4 during the winding and unwinding process is effectively reduced, ensuring the service life of the cable and the airbag 4. Furthermore, the airbag 4 can be actively rotated by the motor 6, which can further reduce wear on the cable and the airbag 4.

[0034] Furthermore, such as Figure 3 , Figure 4 and Figure 5As shown, the inflation assembly includes an L-shaped tube 7, an air collection box 9, and a drain pipe 10. There are two L-shaped tubes 7, and each air guide pipe 3 has an L-shaped tube 7 movably inserted into the side away from the motor 6 along the first direction. Each L-shaped tube 7 is provided with a first one-way exhaust valve 8. The air collection box 9 is fixedly installed on the side of the first U-shaped frame 2 where the L-shaped tubes 7 are located, and a driving component is provided inside the air collection box 9. The driving component is used to guide the gas in the air collection box 9 into the air guide pipe 3 and the airbag 4 through the L-shaped tubes 7. The drain pipe 10 is fixedly inserted into the bottom of the air collection box 9, and the bottom end of the drain pipe 10 is fixedly sleeved with an air supply box 11. The ends of the two L-shaped tubes 7 away from the air guide pipe 3 are respectively fixedly inserted into the bottom and side surfaces of the air supply box 11. A second one-way exhaust valve 13 is provided on the drain pipe 10.

[0035] In specific implementation, taking the winding of cables of different diameters as an example, firstly, one end of the cable is placed between two conveying grooves 5. Then, the drive unit is started to make the gas in the gas collection box 9 flow through the guide pipe 10 to the gas delivery box 11, and then through two L-shaped pipes 7 through the air guide pipe 3 to the two air bags 4, causing the air bags 4 to inflate. Since the air bags 4 inflate uniformly and the cross-section of the cable is circular, it can completely wrap the cables of different diameters. Then, the motor 6 is turned on to make the two air guide pipes 3 rotate, so that the cable can be conveyed, thus achieving the effect of conveying different cables.

[0036] It should be noted that for the rotational installation of the air guide tube 3, two sets of bearings can be fixedly installed on the first U-shaped frame 2. Each set of bearings consists of two bearings, which are installed symmetrically. Both ends of each air guide tube 3 are fixedly inserted into the two bearings in each set, so that it can rotate normally. The L-shaped tube 7 is movably inserted into the air guide tube 3. Since the bearings are existing technology and are not a problem that needs to be solved in the background technology of this specification, they will not be explained in detail in this specification.

[0037] Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, the length of the gas collection box 9 extends along the second direction. The driving component includes a piston plate 14 and an electric push rod 15. The piston plate 14 is slidably installed in the gas collection box 9. The electric push rod 15 is fixedly installed on one side of the gas collection box 9 along the second direction. The driving end of the electric push rod 15 extends into the gas collection box 9 and is fixedly connected to the piston plate 14. A one-way air intake valve 12 is provided at the end of the gas collection box 9 away from the electric push rod 15 along the second direction. The drain pipe 10 is connected to the end of the gas collection box 9 away from the electric push rod 15 along the second direction. The piston plate 14 reciprocates by extending and retracting the drive end of the electric push rod 15. As the piston plate 14 slides towards the electric push rod 15, a negative pressure is created on the side of the piston plate 14 and the air collection box 9 away from the electric push rod 15, drawing external air into the air collection box 9 through the one-way intake valve 12. When the piston plate 14 moves away from the electric push rod 15, it compresses the space between the piston plate 14 and the side of the air collection box 9 away from the electric push rod 15, thus pushing the gas in that space towards the drainage pipe 10. This reciprocating motion inflates the airbag 4. This drive mechanism, combined with the air collection box 9, has a simple structure, lower cost compared to air compressors, and is highly economical.

[0038] Furthermore, such as Figure 4 and Figure 5 As shown, the inflation assembly also includes a diverter plate 17, which is fixedly installed inside the air supply box 11. The diverter plate 17 divides the inner cavity of the air supply box 11 into a first air chamber 24 and a second air chamber 25. The first air chamber 24 is connected to an L-shaped pipe 7, and the second air chamber 25 is connected to another L-shaped pipe 7. The diverter plate 17 divides the air outlet of the guide pipe 10 into a first air outlet and a second air outlet. The first air outlet is connected to the first air chamber 24, and the second air outlet is connected to the second air chamber 25. By setting the diverter plate 17, the gas introduced into the air supply box 11 by the guide pipe 10 can be divided into two parts and delivered to the two air bags 4 respectively, ensuring the uniformity of inflation of the two air bags 4.

[0039] Optionally, a solenoid valve 16 is provided on one side of the airbag 4. The solenoid valve 16 is used to connect the air inside the airbag 4 with the outside air. By setting the solenoid valve 16, the cable winding and unwinding device can automatically control the solenoid valve 16 to discharge the gas inside the airbag 4 after the cable winding and unwinding operation is completed, so as to facilitate the next use of the cable winding and unwinding device.

[0040] In some embodiments, such as Figure 1 and Figure 2As shown, the winding mechanism includes a motor 18 and a take-up roller 19. The take-up roller 19 is rotatably mounted on the mounting frame 1, and the motor 18 is fixedly mounted on the bottom of the mounting frame 1. The drive shaft of the motor 18 passes through the mounting frame 1 and is connected to the take-up roller 19 for transmission. The rotation axis of the take-up roller 19 extends vertically. The take-up roller 19 is driven to rotate by the motor 18 to realize the cable winding and unwinding operation. At the same time, the length of the cable between the winding mechanism and the clamping mechanism can be controlled by controlling the speed of the motor 18 and the motor 6. This avoids the cable being too tight between the winding mechanism and the clamping mechanism, which would increase the friction loss between the cable and the airbag 4, or avoids the cable being too loose between the winding mechanism and the clamping mechanism, which would affect the winding density of the take-up roller 19.

[0041] Furthermore, the cable winding and unwinding device also includes an adjustment assembly, which is mounted on the mounting frame 1 and located between the winding mechanism and the first U-shaped frame 2 along the second direction. The adjustment assembly includes a second U-shaped frame 20, a cylinder 21, and a fixed cylinder 22. The second U-shaped frame 20 is mounted on the mounting frame 1, the cylinder 21 is located on top of the second U-shaped frame 20, and the fixed cylinder 22 is located inside the second U-shaped frame 20. The cylinder 21 is kinetically connected to the fixed cylinder 22 to drive the fixed cylinder 22 to move vertically, through which the cable passes. By using the cylinder 21 to push the fixed cylinder 22, the height of the cable inserted into the fixed cylinder 22 and wound around the take-up roller 19 is adjusted, preventing the cable from being concentrated at the same position on the take-up roller 19 during winding and improving the space utilization of the take-up roller 19.

[0042] In addition, to facilitate the counting of cable length, a roller counter can be installed at a suitable position on the mounting frame 1. The length of the moving cable can be counted by the rotation of the take-up roller 19. The working principle of the roller counter is mainly based on the interaction of rollers, gears and digital disks. Through the rolling of the rollers and the transmission of the gears, the mechanical motion is converted into digital display to realize the counting function. Since the roller counter is existing technology and is not a problem that needs to be solved in the background technology of this specification, it will not be described in detail in this specification.

[0043] Furthermore, the adjusting assembly also includes ball bearings 23, with multiple ball bearings 23 spaced apart on the inner wall of the fixed cylinder 22. The ball bearings 23 effectively reduce frictional loss between the cable and the fixed cylinder 22 during cable transmission, ensuring the cable's product quality.

[0044] like Figures 1 to 5 As shown, embodiments of the present invention also provide a method for operating a cable winding and unwinding device, which includes the following steps:

[0045] S10. Pass the free end of the cable through the clamping groove formed by the two airbags 4 in the clamping mechanism of the cable winding and unwinding device, and wind the free end of the cable into the winding mechanism.

[0046] S20. Activate the inflation component of the clamping mechanism to inflate the airbag 4 and deform it to clamp the cable.

[0047] S30. Start the winding mechanism to wind up the cable.

[0048] This cable winding method is simple to operate. By inflating two spaced airbags 4 using an inflation component, it can accommodate cables of different diameters, effectively guiding and limiting the cable winding and unwinding operations. This reduces the occurrence of cable deviation and entanglement during the winding and unwinding process, offering high compatibility, ease of operation, and saving time and effort. The airbags 4 are inflated for wrapping and clamping, effectively improving the fit of cables of different diameters, resulting in a larger contact area for the cable and a more balanced clamping force from the airbags 4 around the cable. This prevents deformation or damage caused by excessive local clamping force.

[0049] Furthermore, following step S30, step S40 is included: starting and adjusting the motor 6 of the clamping mechanism to drive the air guide tube 3 and the air bag 4 to rotate, thereby adjusting the length of the cable between the clamping mechanism and the winding mechanism. By controlling the speed of the motor 18 of the winding mechanism and the motor 6, the length of the cable between the winding mechanism and the clamping mechanism is controlled. This avoids the cable between the winding mechanism and the clamping mechanism from being too tight, which would increase the frictional loss between the cable and the air bag 4 and prevent the cable from being too tightly wound, or avoids the cable between the winding mechanism and the clamping mechanism from being too loose, which would affect the winding density of the take-up roller 19.

[0050] Of course, when unwinding the cable, the free end of the cable wound on the take-up roller 19 of the winding mechanism is released and passed through the clamping groove formed by the two airbags 4 to the designated position. The inflation component is started to inflate the airbags 4, causing the airbags 4 to deform and clamp the cable. Then the motor 18 of the winding mechanism and the motor 6 of the clamping mechanism are started to unwind the cable in an orderly manner, which effectively improves the guiding limit of the cable unwinding and reduces the situation of the cable drifting randomly during unwinding.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
