Description

Technical Field

[0001] This utility model relates to the field of cable length measurement technology, and in particular to a cable length measurement device. Background Technology

[0002] Accurate length measurement is crucial in the production, processing, and use of wires and cables. Precise length measurement not only aids in quality control during production but also ensures compliance with relevant standards and requirements during sales and use.

[0003] Currently, various wire and cable length measuring devices exist on the market. For example, a wire and cable length measuring device, disclosed in publication number CN221992655U, includes a base plate, a connecting frame, and a fixed frame. A measuring turntable, a first turntable, and a second turntable are mounted on the fixed frame. A measuring wheel, a rubber wheel, and a tension wheel are respectively installed at the center of each turntable, and each wheel has a corresponding side ring slidably mounted on it. A movable plate is also slidably mounted on the fixed frame, and each side ring is rotatably mounted on the movable plate. This device ensures the cable remains straight by allowing it to slide within a space of the same width as the device itself, thus ensuring the accuracy of the measurement results. Simultaneously, the tension wheel design prevents measurement errors caused by cable slack or excessive tension.

[0004] However, the existing technologies still have some shortcomings. In practical applications, wires and cables of different specifications have different thicknesses, and the tension of the cables changes continuously during transportation. Existing metering devices are not suitable for adaptive tension adjustment of the cables being measured, and cannot automatically adjust according to the real-time tension of the cables during transportation to ensure that the cables are always under appropriate tension. Furthermore, they are not suitable for adaptive limit clamping based on different cable thicknesses. When dealing with cables of varying thicknesses, it is difficult to provide stable and appropriate limiting force, thus reducing the flexibility of use and affecting the accuracy and stability of cable length measurement to some extent. Therefore, developing a wire and cable length metering device that can adaptively adjust tension and adaptively limit clamp for cables of different thicknesses is of significant practical importance. Utility Model Content

[0005] The purpose of this invention is to provide a wire and cable length measuring device that achieves adaptive limit clamping for cables of different thicknesses and adaptive adjustment of cable tension, effectively improving the accuracy and stability of cable length measurement. It also has the advantages of stable structure and reliable operation, and has broad application prospects in the field of wire and cable length measurement.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A device for measuring the length of wires and cables, comprising:

[0008] A metering base is provided, with a gantry frame fixedly connected to its top. A metering component for measuring cable length is installed on the gantry frame. A limiting component for limiting the cable to be measured is installed on the top of the gantry frame and at the position corresponding to the metering component. Guiding components for guiding the cable to be measured are installed on both sides of the top of the metering base.

[0009] The aforementioned wire and cable length measuring device includes a measuring shaft rotatably mounted on the gantry frame, a measuring wheel fixedly connected to the measuring shaft, and an encoder installed at the end of the measuring shaft.

[0010] In the aforementioned wire and cable length measuring device, the limiting component includes a mounting base fixedly connected to the gantry frame, a stop spring fixedly connected to the bottom of the mounting base, a lifting frame fixedly connected to the bottom of the stop spring, and a limiting wheel for use with the measuring wheel installed at the bottom of the lifting frame.

[0011] In the aforementioned wire and cable length measuring device, both sides of the bottom of the mounting base are fixedly connected to limit telescopic rods, and the other end of the limit telescopic rods is fixedly connected to the top of the lifting frame.

[0012] In the aforementioned wire and cable length measuring device, the guiding component includes a mounting slide fixedly connected to the top of the measuring base. A connecting spring is fixedly connected to the bottom of the inner wall of the mounting slide, and a connecting slider is fixedly connected to the other end of the connecting spring. A lifting seat is fixedly connected to the top of the connecting slider, and a guide wheel for guiding the cable to be measured is installed on the top of the lifting seat.

[0013] In the aforementioned wire and cable length measuring device, the connecting slider is slidably connected to the inner wall of the mounting housing.

[0014] In the aforementioned wire and cable length measuring device, limit sliders are fixedly connected to both sides of the connecting slider, and a limit groove matching the limit slider is provided on the side of the inner wall of the mounting housing at the position corresponding to the limit slider.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. In this utility model, a wire and cable length measuring device is realized. The abutment spring drives the limit wheel to closely approach the measuring wheel, which can adapt to cables of different thicknesses, ensure the friction between the cable and the measuring wheel, and improve the measurement accuracy. The connecting spring 503 can automatically extend and retract according to the cable tension, and cooperate with the guide wheels of the guide components on both sides to ensure stable cable conveying tension and avoid measurement errors.

[0017] 2. Adaptive Limit Clamping for Cables of Different Thicknesses: When measuring cable length, one end of the cable passes sequentially between the left guide assembly, the measuring wheel, and the limit wheel, and then through the right guide assembly. As the cable passes between the measuring wheel and the limit wheel, the spring force of the contact spring causes the limit wheel to press against the measuring wheel. This design allows the limit assembly to automatically adjust the distance between the limit wheel and the measuring wheel according to the cable's thickness, thus adapting to the limiting requirements of cables of different thicknesses. By ensuring sufficient friction between the cable and the measuring wheel, the cable can smoothly drive the measuring wheel to rotate during passage, effectively ensuring the accuracy of cable length measurement and improving the device's applicability to cables of different specifications.

[0018] 3. Adaptive Cable Tension Adjustment: Guiding components are installed on both sides of the top of the metering base. Guide wheels within these components guide and transport the cable. During cable transport, the connecting spring plays a crucial role. It automatically adjusts its position based on the cable tension. When the cable tension is too high, the connecting spring is stretched, and the guide wheel position changes accordingly, relieving the cable tension. When the cable tension is too low, the connecting spring contracts, and the guide wheel applies a certain pulling force to the cable, maintaining a suitable tension. This adaptive adjustment mechanism ensures the stability of cable transport, avoids measurement errors caused by uneven cable tension, and further improves the accuracy and reliability of cable length measurement.

[0019] 4. Stable Structure and Reliable Operation: In the limiting assembly of this utility model, limiting telescopic rods are fixedly connected to both sides of the bottom of the mounting base, and the other end of the limiting telescopic rods is fixedly connected to the top of the lifting frame. During the limiting wheel's up-and-down movement for limiting adjustment, the limiting telescopic rods provide stable guidance, preventing the lifting frame from shifting and ensuring that the limiting wheel always accurately matches the measuring wheel. Simultaneously, the connecting slider in the guiding assembly is slidably connected to the inner wall of the mounting housing, and limiting sliders are fixedly connected to both sides of the connecting slider. The inner wall of the mounting housing has limiting grooves that match the limiting sliders. This structural design makes the connecting slider slide more smoothly within the mounting housing, ensuring the stability of the guide wheel during adaptive adjustment, thereby improving the overall operational reliability of the device and extending its service life.

[0036] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] Please refer to Figures 1 to 5 As shown, an embodiment of the present invention provides a wire and cable length measuring device, comprising: a measuring base 1, a gantry frame 2 fixedly connected to the top of the measuring base 1, a measuring component 3 for measuring cable length installed on the gantry frame 2, a limiting component 4 for limiting the cable to be measured installed on the top of the gantry frame 2 and at the position corresponding to the measuring component 3, and a guiding component 5 for guiding the cable to be measured installed on both sides of the top of the measuring base 1.

[0038] By adopting the above technical solution, the abutment spring 4021 drives the limit wheel 4011 to press against the measuring wheel 3011, which can adapt to cables of different thicknesses, ensuring the friction between the cable and the measuring wheel 3011 and improving the measurement accuracy. The connecting spring 503 can automatically extend and retract according to the cable tension, and together with the guide wheels 5011 of the guide components 5 on both sides, it ensures stable cable conveying tension and avoids measurement errors. In addition, the limit telescopic rod 403 guides the movement of the limit wheel 4011 to prevent deviation. The connecting slider 5021, the limit slider 504, and the limit groove 5041 work together to ensure that the guide wheel 5011 is adjusted smoothly, making the device structurally stable, reliable in operation, and with broad application prospects.

[0039] In order to accurately measure the cable length, in this embodiment:

[0040] The metering component 3 includes a metering shaft 301 rotatably mounted on the gantry 2. A measuring wheel 3011 is securely connected to the metering shaft 301. An encoder 3012 is also installed at the end of the metering shaft 301. The metering shaft 301 drives the measuring wheel 3011 to rotate. The encoder 3012 can accurately record the number of rotations of the measuring wheel 3011, and then accurately calculate the length of the cable based on the circumference of the measuring wheel 3011, providing reliable data support for the accurate measurement of cable length.

[0041] In order to accommodate the limiting requirements of cables of different thicknesses, in this embodiment:

[0042] The limiting component 4 includes a mounting base 402 fixedly connected to the gantry 2. A retaining spring 4021 is fixedly connected to the bottom of the mounting base 402. A lifting frame 401 is fixedly connected to the bottom of the retaining spring 4021. A limiting wheel 4011 is installed at the bottom of the lifting frame 401 to cooperate with the measuring wheel 3011. The elastic force of the retaining spring 4021 ensures that the limiting wheel 4011 is always close to the measuring wheel 3011. When cables of different thicknesses pass between the measuring wheel 3011 and the limiting wheel 4011, the limiting wheel 4011 can automatically adjust its position under the action of the retaining spring 4021 to ensure effective limiting of the cable and ensure sufficient friction between the cable and the measuring wheel 3011, so that the cable can smoothly drive the measuring wheel 3011 to rotate, thus improving the applicability of the device to cables of different specifications.

[0043] To ensure the stability of the movement of the limit wheel 4011, in this embodiment:

[0044] Limiting telescopic rods 403 are fixedly connected to both sides of the bottom of the mounting base 402, and the other end of the limiting telescopic rods 403 is fixedly connected to the top of the lifting frame 401. When the limiting wheel 4011 moves up and down with the change of cable thickness, the limiting telescopic rods 403 can play a stable guiding role, prevent the lifting frame 401 from deviating, ensure that the limiting wheel 4011 always accurately matches the meter wheel 3011, ensure the stable operation of the limiting component 4, and further improve the accuracy of cable length measurement.

[0045] In order to achieve adaptive tension adjustment during cable transmission, in this embodiment:

[0046] The guiding component 5 includes a mounting slide 502 fixedly connected to the top of the metering base 1. A connecting spring 503 is fixedly connected to the bottom of the inner wall of the mounting slide 502, and a connecting slider 5021 is fixedly connected to the other end of the connecting spring 503. A lifting seat 501 is fixedly connected to the top of the connecting slider 5021, and a guide wheel 5011 for guiding the cable to be metered is installed on the top of the lifting seat 501. The connecting slider 5021 is slidably connected to the inner wall of the mounting slide 502. The connecting spring 503 can automatically extend and retract according to the tension of the cable. When the cable tension is too high, the connecting spring 503 is stretched, and the position of the guide wheel 5011 changes to relieve the cable tension. When the cable tension is too low, the connecting spring 503 retracts, and the guide wheel 5011 applies tension to the cable to maintain a suitable tension state. This adaptive adjustment mechanism ensures the stability of cable transportation and avoids metering errors caused by uneven cable tension.

[0047] To further improve the smoothness of the movement of the guide wheel 5011, in this embodiment:

[0048] Both sides of the connecting slider 5021 are fixedly connected to limit sliders 504. The inner wall of the mounting housing 502 is provided with a limit groove 5041 that matches the limit slider 504. The cooperation between the limit slider 504 and the limit groove 5041 makes the connecting slider 5021 slide more smoothly in the mounting housing 502, thereby ensuring the stability of the guide wheel 5011 in the adaptive adjustment process and reducing the impact of the guide wheel 5011 shaking on cable delivery and metering.

[0049] The working principle of this utility model is as follows:

[0050] When measuring cable length, one end of the cable is first passed sequentially through the guide wheel 5011 of the left guide assembly 5, then through the measuring wheel 3011 and the limiting wheel 4011, and finally through the guide wheel 5011 of the right guide assembly 5. As the cable passes between the measuring wheel 3011 and the limiting wheel 4011, the abutment spring 4021, through its elastic force, drives the lifting frame 401 and the limiting wheel 4011 to press against the measuring wheel 3011. This design allows the limiting assembly 4 to adapt to cables of different thicknesses, ensuring sufficient friction between the cable and the measuring wheel 3011. This ensures that the cable can smoothly drive the measuring wheel 3011 to rotate during passage, laying the foundation for accurate cable length measurement.

[0051] Meanwhile, guide components 5 are installed on both sides of the top of the metering base 1, with guide wheels 5011 responsible for guiding and conveying the cable. During cable conveying, the connecting spring 503 automatically extends and retracts according to the cable tension. When the cable tension changes, the connecting spring 503 drives the connecting slider 5021 to slide within the mounting housing 502, thereby adjusting the position of the guide wheel 5011 and achieving adaptive adjustment of the cable tension. Moreover, the setting of the limiting telescopic rod 403 ensures the stability of the movement of the limiting wheel 4011, and the cooperation between the limiting slider 504 and the limiting groove 5041 ensures the stability of the movement of the guide wheel 5011, further ensuring the smoothness of cable conveying, and ultimately ensuring the accuracy and reliability of cable length measurement.
