Description

Technical Field

[0001] This utility model relates to a cable winding device, specifically a cable electronic measurement and winding device based on a measuring wheel for precise length counting, belonging to the field of cable winding technology. Background Technology

[0002] Cable reels are cable winding devices that provide power, control power, or control signals to large mobile equipment. They are widely used in heavy machinery and equipment with similar operating conditions, such as port gantry cranes, container cranes, ship loaders, and tower cranes.

[0003] A search revealed a Chinese patent with publication number CN209536684U, which discloses an electronic cable measurement and winding device based on a measuring wheel for precise length counting. Specifically, it relates to the field of cable winding and includes a winding device and a meter counting device. The winding device comprises a motor, a spool, and a winding reel. The output shaft of the motor is connected to one end of the spool. The winding reel is fitted onto the spool. The motor drives the winding reel to rotate, achieving automatic cable winding. A photoelectric encoder detects the rotation angle of the indexing plate, measures the length of the wound cable, and displays it on a screen.

[0004] While the above solutions can measure the length of the wound cable, the winding devices in the aforementioned patents are difficult to adapt to diverse winding scenarios and are difficult to control costs. Therefore, they are not suitable for small-scale, low-cost applications such as home use and individual construction. To address these issues, we provide a cable electronic measurement and winding device based on a measuring wheel for precise length counting. Utility Model Content

[0010] Preferably, a third rotating shaft is rotatably connected to the inner wall of the first fixing frame, and a rotating disk is slidably connected to the outer surface of the third rotating shaft. The rotating disk can support the wound cable and prevent tangling during the winding process.

[0011] Preferably, a support column is fixedly connected to one side of the first fixing frame, and a measuring wheel is rotatably connected to the upper end of the support column. A photoelectric encoder is fixedly connected to the outer surface of the measuring wheel. When the cable is wound up, it drives the measuring wheel to rotate.

[0016] 2.

The cable is tightly attached to the measuring wheel, eliminating slippage between the cable and the measuring wheel and ensuring that the number of rotations of the measuring wheel strictly corresponds to the length of the cable. The measuring wheel on the support column is an independent measurement reference with a fixed diameter. The photoelectric encoder generates a signal by detecting the number of rotations of the measuring wheel, and the meter counter calculates the length accordingly. This measurement method, independent of the winding disk, ensures that the measurement results are not affected by changes in the diameter of the winding disk, thus guaranteeing the accuracy and consistency of the length data throughout the entire process.

[0023] This utility model provides a cable electronic measurement and winding device based on a measuring wheel for precise length counting.

[0024] Please see Figure 3 and Figure 4The system includes a first fixed frame 1, a support column 19 fixedly connected to one side of the first fixed frame 1, a measuring wheel 20 rotatably connected to the upper end of the support column 19, and a photoelectric encoder 21 fixedly connected to the outer surface of the measuring wheel 20. The support column 19 is installed on one side of the first fixed frame 1 for fixing. The measuring wheel 20 is installed on the support column 19. When the cable is wound up, it can drive the measuring wheel 20 to rotate. When the measuring wheel 20 rotates, the photoelectric encoder 21 installed on the measuring wheel 20 can rotate with the measuring wheel 20, thereby identifying the number of rotations of the measuring wheel 20. A third rotating shaft 13 is rotatably connected to the inner wall of the first fixed frame 1. A rotating disk 14 is slidably connected to the outer surface of the third rotating shaft 13. The third rotating shaft 13 is installed on the first fixed frame 1 and can rotate within the first fixed frame 1. The rotating disk 14 is installed on the third rotating shaft 13. When the cable is wound up, the rotating disk 14 can slide back and forth on the third rotating shaft 13 to prevent the wound cable from getting tangled.

[0025] The inner wall of the first fixing frame 1 is rotatably connected to the outer surface of the first rotating shaft 5. The inner side of the slot 6 is inserted into one side of the second rotating shaft 8. The first rotating shaft 5 is mounted on the first fixing frame 1. The slot 6 is provided on the first rotating shaft 5. The second rotating shaft 8 is inserted into the slot 6. When the first rotating shaft 5 rotates, it can drive the second rotating shaft 8 to rotate synchronously, thereby driving the winding reel 10 to wind up the cable. The second fixing frame 11 is fixedly connected to one side of the first fixing frame 1.

[0026] The inner wall of the second fixed frame 11 is slidably connected to a slide rod 16, and a spring 18 is sleeved on the outer surface of the slide rod 16. The upper end of the spring 18 is fixedly connected to the lower surface of the second fixed frame 11, and the lower end of the spring 18 is fixedly connected to the upper surface of the pressure block 17. The spring 18 is mounted on the slide rod 16, and the upper and lower ends of the spring 18 are mounted on the second fixed frame 11 and the pressure block 17. The slide rod 16 can make the pressure block 17 press on the measuring wheel 20, which can prevent the cable from slipping when winding the cable and causing measurement errors.

[0027] A pressure block 17 is fixedly connected to the lower end of the slide rod 16. The slide rod 16 is mounted on the second fixed frame 11. Under the action of the spring 18, the slide rod 16 can slide within the second fixed frame 11. The pressure block 17 is mounted on the slide rod 16. Under the action of the spring 18, the pressure block 17 can press the cable. A meter counter device 12 is fixedly connected to the lower surface of the second fixed frame 11. The second fixed frame 11 is mounted on one side of the first fixed frame 1 and serves to fix it. The meter counter device 12 is mounted on the second fixed frame 11. The meter counter device 12 can sense the number of rotations of the photoelectric encoder 21. After the meter counter device 12 senses the number of rotations of the photoelectric encoder 21, it can calculate the length of the cable by counting the number of rotations.

[0028] Please see Figure 1 and Figure 2 A rotating handle 2 is rotatably connected to the inner wall of the first fixed frame 1. A first spur gear 3 is fixedly connected to one end of the rotating handle 2. The first spur gear 3 meshes with a second spur gear 4. A first rotating shaft 5 is fixedly connected to the middle of the second spur gear 4. A slot 6 is provided on the inner wall of the first rotating shaft 5. A limit rod 7 is inserted into the inner side of the slot 6. The rotating handle 2 is installed in the first fixed frame 1. When the rotating handle 2 is rotated, the first spur gear 3 installed on the rotating handle 2 can be rotated. The first spur gear 3 can drive the second spur gear 4 to rotate. The second spur gear 4 can drive the first rotating shaft 5 to rotate. This can drive the second rotating shaft 8 installed in the first rotating shaft 5 to rotate, so that the winding reel 10 can wind up the cable.

[0029] A second rotating shaft 8 is fixedly connected to the outer surface of the limiting rod 7. A limiting plate 9 is fixedly connected to the outer surface of the second rotating shaft 8. A winding reel 10 is inserted into the outer surface of the second rotating shaft 8. A rotating groove 15 is provided at the upper end of the first fixing frame 1. The inner side of the rotating groove 15 is rotatably connected to the outer surface of the second rotating shaft 8. The first fixing frame 1 is provided with a rotating groove 15. The second rotating shaft 8 is placed in the rotating groove 15. After the winding reel 10 has finished winding the cable, the wound reel 10 can be taken out for quick replacement.

[0030] The meter counter device 12 and the photoelectric encoder 21 in this application are common electrical devices in the prior art. Their models or specific structures will not be described in detail in this application. Their principles are based on the prior art.

[0031] Working principle: The operator manually cranks the handle 2, which rotates the first spur gear 3. The first spur gear 3 meshes with the second spur gear 4, transmitting power to the first rotating shaft 5, which is fixed to the second spur gear 4. The first rotating shaft 5 has a slot 6 inside, and the second rotating shaft 8 is inserted into the slot 6 through the limiting rod 7, thus realizing the synchronous transmission of power from the first rotating shaft 5 to the second rotating shaft 8. The winding reel 10 to be wound is fitted onto the second rotating shaft 8 and fixed in position by the limiting plate 9. Finally, the power is transmitted to the winding reel 10, causing it to rotate and begin winding the cable. Before winding, the cable passes through an independent measuring wheel 20. At the measuring wheel 20, a clamping device presses the cable tightly against the surface of the measuring wheel 20. The pressure provided by the spring 18 ensures that there is no relative slippage between the cable and the measuring wheel 20, eliminating slippage. The device also has a rotating disc 14, which can rotate along the first spur gear 5. The three rotating shafts 13 slide to support and guide the cable, preventing tangling during winding. When the cable is wound at a constant speed, it drives the measuring wheel 20, which is in close contact with its surface, to rotate synchronously. The measuring wheel 20 is an independent reference wheel with a constant diameter. A photoelectric encoder 21 is installed on the measuring wheel 20. Each time the measuring wheel 20 rotates, the photoelectric encoder 21 generates one or more pulse signals. The meter counter device 12 receives the pulse signals and calculates the length according to the formula: cable length = circumference of measuring wheel 20 × number of turns corresponding to the pulse signal. Since the diameter of the measuring wheel 20 is fixed, the length is strictly proportional to the number of turns. The meter counter device 12 displays the calculated length value in real time for the operator to read. This measurement method, which is independent of the winding reel, ensures that the measurement results are not affected by the diameter change caused by the accumulation of cable on the winding reel 10, thus guaranteeing the accuracy and consistency of the length data throughout the winding process.
