Description

Technical Field

[0001] The utility model relates to the technical field of cable transportation, in particular to a tension control device for cable transportation. Background Art

[0002] Cable transportation refers to the process of safely and efficiently transporting power, telecommunications, and data transmission cables from one location to another. This system is designed to protect the cables from physical damage while ensuring they remain neatly organized during transportation, reducing wear and stretching, and thus extending their service life. During transportation, cables are subject to tension in various directions, requiring the use of tension control devices to effectively manage these forces and prevent damage or breakage due to excessive stretching.

[0003] Tension control devices come in various types, including spring tension control, weight tension control, and pneumatic tension control. These devices are selected based on the specific cable type, transportation environment, and operational requirements to ensure safe and efficient cable transportation. Spring tension control utilizes the elastic properties of the spring to maintain appropriate cable tension. During cable transportation, cable tension varies depending on load or motion. The spring deforms in response to external forces, adjusting the cable tension.

[0004] Traditional spring tension control devices have significant shortcomings in adjusting cable tension. These devices typically consist of a set of springs, pulleys, or guide wheels. As the cable passes through these components, the springs exert a pulling force to maintain cable tension. However, the tension of these springs is typically set based on the average cable demand and is typically fixed, making it impossible to adjust in real time to actual operating conditions. For example, when transporting thinner cables, if the spring tension is set too high, the cable will not be able to withstand the excessive pulling force, making it impossible to adjust the cable tension in a timely and accurate manner, resulting in the cable being too tight. Excessive tension not only affects cable transportation efficiency but can also shorten the cable's service life. Furthermore, the inflexible tension control also makes the cable less adaptable during transportation, limiting its flexibility and effectiveness in practical applications. Therefore, there is an urgent need to improve traditional tension control devices to achieve more dynamic and precise tension adjustment, thereby improving the overall performance of cable transportation systems. Utility Model Content

[0005] In order to remedy the above deficiencies, the present invention provides a tension control device for cable transportation, aiming to improve the problem that the cable tension cannot be adjusted in time for different cable models and transportation speeds.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment of a tension control device for cable transportation, comprising a bracket 1, a cross bar 2 fixedly connected to the inside of the bracket 1, an adjustment mechanism provided inside the cross bar 2 to achieve precise adjustment of the cable tension, a fixed block 3 fixedly connected to one side of the bracket 1, a limiting slot 4 provided inside the fixed block 3 to limit the position of the adjustment mechanism to ensure its stability during operation, a connecting mechanism fixedly connected to the bottom of the adjustment mechanism, a support rod 2 9 provided at the bottom of the connecting mechanism, a limiting mechanism provided on both sides of the support rod 2 9 to prevent the support rod 2 9 from being displaced or damaged during operation, a guide wheel 11 rotatably connected to the bottom of the support rod 2 9, which is responsible for guiding the smooth transportation of the cable and ensuring the stability and safety of the cable during transportation, a cross bar 2 12 fixedly connected to one side of the bracket 1, and a guide wheel 2 13 rotatably connected to the top of the cross bar 2 12, which cooperates with the guide wheel 11 to control the running direction of the cable;

[0032] The adjusting mechanism includes an adjusting bolt 6, which is threadedly connected to the inside of the cross bar 2. By rotating the adjusting bolt 6, the height of the support rod 5 can be adjusted, thereby affecting the tension of the cable. The bottom of the adjusting bolt 6 is rotatably connected to the support rod 5. A spring 8 is provided at the bottom of the support rod 5. One end of the spring 8 is fixedly connected to the bottom of the support rod 5, and the other end is fixedly connected to the top of the support rod 2 9, forming an effective elastic tension adjustment system, which can automatically adjust the tension of the cable according to actual needs. The limiting mechanism includes a limiting block 10, one side of the limiting block 10 is fixedly connected to one side of the support rod 2 9, and the limiting block 10 is slidably connected to the inside of the limiting slot 4, ensuring that the movement range of the support rod is within the range allowed by the design, avoiding damage to the equipment caused by excessive movement. The connecting mechanism includes a telescopic rod 7, which is arranged inside the spring 8, one end of the telescopic rod 7 is fixedly connected to the bottom of the support rod 5, and the other end is fixedly connected to the top of the support rod 2 9, ensuring effective connection and coordinated action between the two during the adjustment process, further improving the stability and reliability of the equipment;

[0033] Specifically, when adjusting the tension of the cable, first rotate the adjusting bolt 6 to drive the support rod 1 5 to move downward, so that the spring 8 is compressed, and then an extrusion force is applied to the support rod 2 9. The support rod 1 5 and the support rod 2 9 are effectively limited by the telescopic rod 7 to ensure the stability and accuracy of the system. Subsequently, the support rod 2 9 is precisely limited inside the limiting groove 1 4 by the limiting block 10 to ensure that its position is not easily offset. Through this ingenious design, the degree of deformation of the adjusting spring 8 can flexibly control the tension of the guide wheel 11 on the cable, ensuring the stability and safety of the cable during transmission, and achieving the ideal effect of effectively adjusting the cable tension. Such a structure not only improves the convenience of adjustment, but also enhances the overall reliability of the cable transmission system.

[0034] Reference Figure 3 , a baffle 14 is fixedly connected to the top of the bracket 1, and the baffle 14 is used to prevent objects or cables from accidentally slipping, ensuring the safety and stability of the equipment during operation. A conical column 15 is fixedly connected to one side of the baffle 14, and the conical column 15 provides support and guidance to guide the movement of other components and improve the overall rigidity of the device. A shell 16 is fixedly connected to the top of the bracket 1, and a limit block 23 is fixedly connected to the inside of the shell 16 to limit the movement range of the component to ensure that the equipment does not accidentally move during operation. A motor 17 is fixedly connected to one side of the shell 16. The motor 17 is the power source of the entire system and is responsible for driving the subsequent threaded rod 20 to rotate. The output end of the motor 17 is fixedly connected to the threaded rod 20, and the rotation of the threaded rod 20 is connected to the limit plate 18 to achieve the limit plate 1 8 precise position adjustment, the housing 16 is internally slidably connected to the limit plate 18, and the limit groove 2 19 is provided inside the limit plate 18 to facilitate its smooth sliding and position adjustment during operation. The limit plate 18 is slidably connected to the outer wall of the limit block 23 through the limit groove 29 to ensure that the limit plate 18 is stably restricted during movement to avoid exceeding the set range. A conical column 22 is fixedly connected to one side of the limit plate 18. The conical column 22 is responsible for further guiding and positioning the movement of the limit plate 18. At the same time, a cavity 21 is provided inside, which may be used to accommodate other mechanical structures or as a channel between components. The internal thread of the limit plate 18 is connected to the outer wall of the threaded rod 20 to form a tight connection, ensuring that the limit plate 18 can adjust its position at any time when driven by the motor 17, thereby achieving precise control of the cable tension;

[0035] Specifically, when installing the winding roller, you only need to easily place the winding roller between the conical column 22 and the conical column 1 15 to start the entire installation process. The output end of the motor 17 drives the threaded rod 20 to rotate through precise design, so that when it rotates, it drives the limit plate 18 to smoothly extend from the shell 16. Under the guidance of the limit block 23 in the shell 16, the limit plate 18 slides precisely in the limit groove 2 19 to limit the position, ensuring the stability of the installation process. Subsequently, the conical column 2 22 is securely inserted into the interior of the winding roller, and the inclined surface of its outer wall cleverly drives the winding roller to automatically reset, thereby achieving rapid installation. This design not only significantly improves the installation efficiency, but also ensures the stability of the winding roller. Next, the cable passes through the guide wheel 2 13 and the guide wheel 1 11 in turn, and the tension of the cable is accurately controlled in an up and down staggered manner, thereby ensuring the safety and stability of the cable during the entire transmission process.

[0036] Working principle: When using the tension control device for cable transportation, first adjust the tension of the cable by rotating the adjusting bolt 6 to drive the support rod 1 5 to descend and then squeeze the support rod 2 9 through the spring 8. The support rod 1 5 and the support rod 2 9 are limited by the telescopic rod 7. Then the support rod 2 9 is limited inside the limiting groove 1 4 by the limiting block 10. Then, the tension of the guide wheel 11 on the cable is adjusted by adjusting the deformation degree of the spring 8, thereby achieving the effect of adjusting the cable tension. When the winding roller needs to be installed, it is only necessary to place the winding roller on the conical column. Between the second 22 and the conical column 15, the output end of the motor 17 drives the threaded rod 20 to rotate, and the threaded rod 20 drives the limit plate 18 to extend out of the shell 16. The limit plate 18 slides in the limit groove 19 through the limit block 23 in the shell 16 for limitation. Then the conical column 22 is inserted into the interior of the winding roller and then drives the winding roller to automatically reset and install through the inclined surface of the outer wall of the conical column 22, thereby achieving the effect of quickly adjusting the winding roller. Then the cable passes through the guide wheel 2 13 and the guide wheel 1 11 in turn, and the tension of the cable is controlled by staggering up and down.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
