Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a cable tension control frame. Background Technology

[0002] Existing tension control testing frames mainly control the tension by adding or removing counterweights during field use. However, due to their single-bar structure, the adjustment process requires manual disassembly or installation of counterweights, and the purchase of counterweights of different weights is also necessary, which increases labor and material costs. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in related technologies. To this end, this utility model provides a cable tension control frame that, through a design combining a swing arm and a counterweight arm, along with a pneumatic cable clamp, achieves precise control of cable tension, reduces reliance on counterweights of varying weights, lowers material costs, and makes the overall tension detection and control frame more economical and efficient.

[0004] This utility model provides a cable tension control frame, comprising:

[0005] A bracket, on the top of which a first spool and a second spool are rotatably mounted, a pneumatic wire clamp is provided on the bracket, and a rotating shaft is provided on the bracket, the rotating shaft being located below the first spool;

[0006] A swing arm is rotatably connected to the rotating shaft. A third reel is provided at the second end of the swing arm. The cable is introduced from the first reel, and then wound around the second and third reels several times before entering the pneumatic cable clamp.

[0007] A counterweight rod is connected to the pendulum rod, and a counterweight block is slidably mounted on the counterweight rod.

[0008] A detector, mounted on the bracket, is used to detect the swing position of the pendulum.

[0009] A further improvement of the tension control frame for cables of this utility model is that the frame includes a base, a vertical pole erected on the base, and a horizontal bar fixedly connected to the vertical pole and in a horizontal position. The first reel, the second reel, and the pneumatic cable clamp are installed on the horizontal bar. The rotating shaft is disposed on the vertical pole, and the detector is installed on the vertical pole and located above the rotating shaft.

[0010] A further improvement of the tension control frame for cables of this utility model is that it further includes a reinforcing plate disposed on the upright, the reinforcing plate being located above the rotating shaft, and a limiting shaft being installed on the reinforcing plate to limit the swing position of the swing arm.

[0011] A further improvement of the tension control frame for cables of this utility model is that a protective cover is provided on the upright, the limiting shaft is rotatably connected to the upright, and the limiting shaft is provided with an eccentric wheel.

[0012] A further improvement of the tension control frame for cables of this utility model is that the upright is provided with a third proximity switch, which is used to detect the position of the limiting shaft.

[0013] A further improvement of the tension control frame for cables of this utility model is that the upright is equipped with a solenoid valve, which is connected to the pneumatic cable clamp.

[0014] A further improvement of the tension control frame for cables of this utility model is that the detector is a first proximity switch and a second proximity switch installed on the frame.

[0015] A further improvement of the tension control frame for cables of this utility model is that the swing arm and the counterweight arm are connected by two connecting blocks.

[0016] A further improvement of the tension control frame for cables of this utility model is that a scale is also provided between the two connecting blocks, and the scale is used to indicate the tension value.

[0017] A further improvement of the tension control frame for cables of this utility model is that a control switch is provided at the top of the frame, and the control switch is connected to the pneumatic cable clamp.

[0018] In this invention, during cable setup, the cable enters from the first reel, passes through the second reel, enters the third reel, exits from the third reel back to the second reel, and after winding several times between the second and third reels, finally exits from the second reel to the pneumatic cable clamp at the rear. The pneumatic cable clamp clamps the cable according to a preset tension value to maintain stable tension during the testing process and prevent the cable from breaking and becoming knotted or loose.

[0019] When the cable tension changes, the pendulum swings accordingly, which in turn moves the counterweight. The movement of the counterweight changes the position of the scale connected to the connecting block, allowing for a direct reading of the current tension value.

[0020] The first and second proximity switches are used to detect the upper and lower limits of the swing arm, respectively, to achieve accurate detection of the swing position of the swing arm. The eccentric wheel, limit shaft and third proximity switch are used together to provide speed regulation for equipment production and to detect the swing rate of the swing arm.

[0021] The pendulum rod, scale, and counterweight rod form a single integrated mechanism. In actual production, the position of the counterweight block above the counterweight rod can be adjusted according to factors such as wire diameter to find the appropriate tension. Because of the scale, the appropriate tension for different cable specifications can be found quickly and accurately when producing cables of different specifications.

[0022] The swing arm maintains a certain tension on the cable. When the swing arm is in the upward position, the equipment production speed is faster; when the swing arm is in the downward position, the equipment production speed is slower. When the cable breaks, the swing arm reaches the lower limit, at which point the third proximity switch issues a cable break alarm, and the pneumatic cable clamp activates to clamp the broken cable.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The following embodiments are used to illustrate this utility model but should not be used to limit its scope.

[0031] The following is combined Figure 1 This invention describes a cable tension control frame, comprising: a support frame, on the top of which a first reel 21 and a second reel 22 are rotatably mounted; a pneumatic cable clamp 7 is mounted on the support frame; and a rotating shaft 33 is mounted on the support frame, located below the first reel 21; a swing arm 32 rotatably connected to the rotating shaft 33; a third reel 23 is mounted at the second end of the swing arm 32; the cable is introduced from the first reel 21, then wound around the second reel 22 and the third reel 23 several times, and then enters the pneumatic cable clamp 7; a counterweight rod 35 connected to the swing arm 32; a counterweight block 36 slidingly mounted on the counterweight rod 35; and a detector mounted on the support frame to detect the swing position of the swing arm 32.

[0032] During cable setup, the cable enters from the first reel 21, passes through the second reel 22 and enters the third reel 23, exits from the third reel 23 and returns to the second reel 22. After being wound several turns between the second reel 22 and the third reel 23, the cable finally exits from the second reel 22 to the pneumatic cable clamp 7 at the rear. The pneumatic cable clamp 7 clamps the cable according to a preset tension value to maintain stable tension of the cable during the testing process and prevent the cable from being pulled apart and becoming knotted or loose.

[0033] The position of the counterweight 36 along the counterweight rod 35 is adjusted to regulate the rotation angle of the pendulum 32, thereby changing the cable tension to accommodate cables of different specifications and materials. When the counterweight 36 moves towards one end of the counterweight rod 35, the pendulum 32 rotates downwards due to gravity, increasing the distance between the third reel 23 and the second reel 22. This reduces the number of cable turns between them, thus decreasing the cable tension. Conversely, when the counterweight 36 moves towards the other end of the counterweight rod 35, the pendulum 32 rotates upwards, decreasing the distance between the third reel 23 and the second reel 22. This increases the number of cable turns, thereby increasing the cable tension. By precisely adjusting the position of the counterweight 36, fine adjustments to the cable tension can be achieved, ensuring a stable tension state during use and improving the accuracy and reliability of testing.

[0034] In a preferred embodiment of the cable tension control frame of this utility model, such as Figure 2 and Figure 3 As shown, the bracket includes a base 11, a vertical rod 12 erected on the base 11, and a horizontal bar 13 fixedly connected to the vertical rod 12 and in a horizontal position. The first reel 21, the second reel 22, and the pneumatic wire clamp 7 are installed on the horizontal bar 13. The rotating shaft 33 is disposed on the vertical rod 12, and the detector is installed on the vertical rod 12 and located above the rotating shaft 33.

[0035] The fixed connection of the base 11, the upright 12 and the crossbar 13 ensures the stable installation of the first reel 21, the second reel 22 and the pneumatic wire clamp 7.

[0036] Preferably, a triangular support plate is provided between the upright 12 and the base 11 to improve the stability of the connection between the upright 12 and the base 11, and a triangular support plate is also provided between the crossbar 13 and the upright 12 to improve the stability of the connection between the upright 12 and the crossbar 13.

[0037] Furthermore, the system also includes a reinforcing plate 8 disposed on the upright 12, located above the rotating shaft 33. A limiting shaft 4 is mounted on the reinforcing plate 8 to limit the swing position of the swing arm 32. The reinforcing plate 8 enhances the strength and stability of the upright 12, ensuring that the entire tension control frame is not easily deformed or damaged under high loads or long-term use. The limiting shaft 4 effectively controls the swing range of the swing arm 32, allowing it to remain in a predetermined position during tension adjustment, avoiding errors or instability caused by excessive swinging.

[0038] Specifically, a protective cover 85 is provided on the upright 12, and the limiting shaft 4 is rotatably connected to the upright 12. An eccentric wheel 81 is provided on the limiting shaft 4. The protective cover 85 is used to limit the rotation position of the eccentric wheel 81. By rotating the eccentric wheel 81, the effective swing range of the swing arm 32 can be adjusted, thereby realizing fine adjustment of cable tension and meeting the diverse needs of cable tension control in different application scenarios.

[0039] Furthermore, the detector consists of a first proximity switch 6 and a second proximity switch 5 installed on the bracket. The first proximity switch 6 and the second proximity switch 5 are respectively located on both sides of the upright 12. The first proximity switch 6 located on the left side of the upright 12 is used to detect the lower limit position of the swing arm 32, and the second proximity switch 5 located on the right side of the upright 12 is used to detect the upper limit position of the swing arm 32, thereby achieving accurate detection of the swing position of the swing arm 32.

[0040] Preferably, the first proximity switch 6 and the second proximity switch 5 can be an inductive proximity switch, a capacitive proximity switch, a photoelectric proximity switch, a Hall effect proximity switch, or an ultrasonic proximity switch.

[0041] Furthermore, the upright 12 is equipped with a third proximity switch 82, which is used to detect the position of the limiting shaft 4. The combination of the eccentric wheel 81, the limiting shaft 4 and the third proximity switch 82 provides speed regulation for equipment production and detects the swing rate of the swing arm 32. However, when the third proximity switch 82 detects that the speed change of the eccentric wheel 81 exceeds the set value, it determines that a wire break or fault has occurred, and then transmits a signal to the pneumatic wire clamp 7, so that the pneumatic wire clamp 7 can quickly clamp the cable and improve the stability of the cable.

[0042] Preferably, the third proximity switch 82 can be an inductive proximity switch, a capacitive proximity switch, a photoelectric proximity switch, a Hall effect proximity switch, or an ultrasonic proximity switch.

[0043] Furthermore, the upright 12 is equipped with a solenoid valve 83, which is connected to the pneumatic cable clamp 7. The solenoid valve 83 is also connected to a first proximity switch 6, a second proximity switch 5, and a third proximity switch 82, facilitating automated control of the cable tension control frame. When the first proximity switch 6 or the second proximity switch 5 detects that the swing arm 32 has reached a preset upper or lower limit position, the solenoid valve 83 responds quickly, clamping or releasing the cable via the pneumatic cable clamp 7, thereby achieving precise adjustment of the cable tension. Simultaneously, the third proximity switch 82 monitors the rotation speed of the limit shaft 4. If an abnormality is detected, the solenoid valve 83 can also promptly trigger the pneumatic cable clamp 7, effectively preventing the cable from loosening due to breakage or malfunction, ensuring the stability and safety of the cable during transmission. This design not only improves the automation level of cable tension control but also greatly enhances the reliability and durability of the equipment.

[0044] Preferably, a wiring port 84 is provided at the bottom of the pole, through which external wiring is connected to the solenoid valve, the first wiring switch, the second wiring switch and the third wiring switch.

[0045] Furthermore, the swing arm 32 and the counterweight arm 35 are connected by two connecting blocks 31.

[0046] Furthermore, a scale 34 is provided between the two connecting blocks 31. The scale 34 indicates the tension value, allowing the operator to intuitively read the current cable tension status without relying on complex measuring tools or equipment. By observing the indication on the scale 34, the operator can quickly adjust the cable tension to ensure it is within a suitable range, thereby further improving the efficiency and stability of cable transmission. In addition, the scale 34 simplifies the equipment maintenance and calibration process, making it easier for staff to regularly inspect and maintain the tension control frame, ensuring its long-term stable operation.

[0047] Furthermore, a control switch 9 is provided at the top of the bracket. The control switch 9 is connected to the pneumatic cable clamp 7. The operator can conveniently control the opening and closing of the pneumatic cable clamp 7 through the control switch 9, thereby realizing the instant adjustment of cable tension, avoiding manual operation when the solenoid valve 83 fails to control, and improving the control effect of the cable.

[0048] Preferably, the swing arm 32, the scale 34, and the counterweight rod 35 are a single integrated mechanism. In actual production, the position of the counterweight block 36 above the counterweight rod 35 can be adjusted according to factors such as wire diameter to find the appropriate tension. Because of the presence of the scale 34, the appropriate tension for different cable specifications can be found quickly and accurately when producing cables of different specifications.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
