Description

Technical Field

[0001] This utility model relates to the field of cable fault detection technology, specifically a cable reel wiring device for automatically detecting the tightness of the winding. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In cable fault detection, the high-voltage output line of the power supply for cable fault location is often insufficient in length. It is necessary to use a professional high-voltage cable reel to extend the cable to the end of the cable being tested. During the cable winding and unwinding process of the professional high-voltage cable reel, it is essential to control the uniformity of the cable arrangement and the tightness of the winding. This requires the use of a cable reel cable arrangement device.

[0004] However, most existing cable reel wiring devices rely on multiple people coordinating and manually intervening to adjust the uniformity and tightness of the wiring. This is not only inefficient and requires a lot of manpower, but also prone to problems such as uneven wiring and loose winding, which adversely affects the use and storage of cables. In addition, the motors in some cable reel wiring devices need to be frequently reversed, which reduces the stability and lifespan of the motor. Traditional wiring structures often use servo motors to solve this problem, but this leads to excessively high operating costs.

[0005] Based on the above reasons, this utility model designs a cable reel routing device that automatically detects the tightness of the winding. It can achieve reciprocating cable routing without the need for motor rotation and can monitor the tightness of the winding, thereby improving motor stability, protecting the cable, improving cable winding efficiency and quality, and reducing usage costs. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cable reel routing device that automatically detects the tightness of the winding. It can achieve reciprocating cable routing without the need for motor rotation and can monitor the tightness of the winding, thereby improving motor stability, protecting the cable, and improving the efficiency and quality of cable winding and unwinding.

[0007] To achieve the above objectives, this utility model provides an automatic cable reel wiring device for detecting the tightness of the winding, including a fixed plate. A reciprocating screw is mounted on the fixed plate via a bearing. One end of the reciprocating screw, located on the outside of the fixed plate, is connected to a synchronous pulley. A guide rod is connected to a waist-shaped hole at the top of the fixed plate. The guide rod passes through and is fitted with a slider fixing frame and a guide wheel. A slider is provided at the bottom of the slider fixing frame. The slider is connected to a sliding tongue via a sliding tongue fixing screw. The sliding tongue engages with a groove on the reciprocating screw. A guide wheel is provided inside the slider fixing frame. A detection spring is mounted on the fixed plate. The detection spring presses against the guide rod. The guide rod is pressed by the cable onto the contact plate of a micro switch. The micro switch is located on the outside of the fixed plate.

[0008] One end of the sliding tongue fixing screw is fixed in the corresponding screw hole on the slider.

[0009] The other end of the sliding tongue fixing screw passes through the sliding tongue fixing hole.

[0010] The fixing hole for the sliding tongue is located at the center of the sliding tongue.

[0011] The sliding tongue can rotate freely around the circumference of the sliding tongue fixing screw.

[0012] The micro switch is connected to the electrical control system.

[0013] There is a cable on the guide wheel, and the cable is located between the slider fixing frame and the guide wheel.

[0014] The diameters on both sides of the guide rod are smaller than the diameter of the middle part.

[0015] The bearings are installed on the inside of the fixed plate.

[0016] The fixing plates are a pair and are respectively installed at both ends of the guide rod.

[0017] The sliding tongue is located in the groove of the reciprocating lead screw.

[0018] Compared with existing technologies, this invention utilizes the principle of a reciprocating lead screw, requiring only a common motor to move the slider back and forth, thereby driving the reciprocating winding of the cable. This reduces the number of motor reversals, improving motor stability and lifespan, and lowering costs. Simultaneously, the combination of a detection spring and a microswitch sensitively senses the pressure of the cable on the guide rod, monitoring and judging the cable tension. This prevents cable damage or tangled winding caused by slack winding, improving the automation and reliability of the cable winding process. Through automatic reciprocating cable laying and monitoring, this invention achieves uniformity in cable laying, greatly reducing insufficient manual intervention and safety hazards. Furthermore, its simple structure, ease of use and maintenance, and excellent performance make it highly effective. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] See Figures 1-5 This utility model provides an automatic cable reel wiring device for detecting winding tightness, including a fixed plate 2. A reciprocating screw 4 is mounted on the fixed plate 2 via a bearing 3. One end of the reciprocating screw 4, located on the outside of the fixed plate 2, is connected to a synchronous pulley 1. A guide rod 12 is connected to the top of the fixed plate 2 in a waist-shaped hole. The guide rod 12 passes through and is fitted with a slider fixing frame 10 and a guide wheel 11. A slider 6 is placed at the bottom of the slider fixing frame 10. The slider 6 is connected to a slider 5 via a slider fixing screw 7. Connected to the slide groove 4-1 on the reciprocating lead screw 4, the slider fixing frame 10 is provided with a guide wheel 11 inside, and a detection spring 9 is installed on the fixing plate 2. The detection spring 9 presses against both ends of the guide rod 12. The cable 13 passes through the middle of the slider fixing frame 10 and the guide wheel 11, and one side is wrapped around the guide wheel 11. When the cable 13 is tightened, the guide wheel 11 will press the guide rod 12 to move, and the guide rod 12 will press the contact piece on the micro switch 8. The micro switch 8 is located on the outside of the fixing plate 2.

[0027] The sliding tongue fixing screw 7 is connected to the sliding tongue 5 through the sliding tongue fixing hole 5-1.

[0028] The fixing hole 5-1 of the sliding tongue is located at the center of the sliding tongue 5.

[0029] The sliding tongue 5 rotates circumferentially along the sliding tongue fixing screw 7.

[0030] The sliding tongue 5 is located in the groove 4-1 of the reciprocating screw 4.

[0031] The micro switch 8 is connected to the electrical control system.

[0032] The guide wheel 11 has a cable 13, which is located between the slider fixing frame 10 and the guide wheel 11.

[0033] The diameters on both sides of the guide rod 12 are smaller than the diameter of the middle part.

[0034] Bearings 3 are installed on the inner side of the fixed plate 2.

[0035] The fixing plates 2 are a pair and are respectively installed at both ends of the guide rod 12.

[0036] The working principle of this utility model is as follows:

[0037] The slider 5 is connected to the slider 6 by the slider fixing screw 7, so that the slider 5 is located in the groove 4-1 of the reciprocating lead screw 4 and can slide and rotate freely. The guide rod 12 passes through the slider fixing frame 10 and the guide wheel 11, and the slider fixing frame 10 and the slider 6 are assembled together.

[0038] The micro switch 8 and the detection spring 9 are respectively mounted on the side and inside of the fixed plate 2.

[0039] A bearing 3 is installed on the inner side of the fixed plate 2, and the reciprocating lead screw 4 passes through the bearing 3 to ensure that the reciprocating lead screw 4 rotates flexibly. At the same time, the guide rod 12 is installed in the corresponding hole above the fixed plate 2. The guide rod 12 presses down on the detection spring 9 to prevent the detection spring 9 from coming out. Check to ensure that the guide rod 12 can press down on the detection spring 9 when it moves, so as to accurately sense the change in winding tension and trigger the micro switch 8, so that it can both guide the slider 6 and work in coordination with the detection spring 9 and the micro switch 8.

[0040] Install the fixing plate 2 in the appropriate position on the cable reel equipment, ensuring a secure installation.

[0041] Synchronous pulley 1 is connected to the drive motor via a synchronous belt, ensuring reliable connection and stable power transmission.

[0042] When the drive motor is turned on, it drives the synchronous pulley 1 to rotate. The synchronous pulley 1 drives the reciprocating screw 4 to rotate, and the sliding tongue 5 connected to the reciprocating screw 4 moves accordingly within the groove 4-1 of the reciprocating screw 4. According to the working principle of the reciprocating screw 4, when the sliding tongue 5 reaches one end of the reciprocating screw 4, it will automatically reverse direction along the groove 4-1, driving the slider 6 to move in the opposite direction. The slider 6 continuously drives the guide wheel 11 to reciprocate. Since the cable 13 is located at the center of the guide wheel 11, the guide wheel 11 continuously and stably performs reciprocating cable laying operation on the cable reel.

[0043] During the winding process, the cable 13 is pressed against the guide rod 12 by the guide wheel 11. Therefore, the guide rod 12 can sense the pressure caused by the tension of the cable 13 winding in real time. The detection spring 9 is pressed by the guide rod 12, so the detection spring 9 can sense the pressure of the cable 13 tension on the guide rod 12 in real time. At the same time, the guide rod 12 also presses down on the contact plate of the micro switch 8. Specifically, the two detection springs 9 press against the two ends of the guide rod 12 respectively. A certain preload is required during installation. In the free state, the detection springs 9 at both ends push the guide rod 12 towards the other end of the oblong hole of the fixing plate 2, away from the contact plate of the micro switch 8. In the working state, the cable 13 passing through the guide wheel 11 is tightened. At this time, the force is transmitted to the guide rod 12 through the guide wheel 11. Under the action of the tension, the guide rod 12 will slide towards the other end in the oblong hole of the fixing plate 2. When it reaches the other end, it will press down on the contact plate of the micro switch 8, triggering the micro switch 8 to control the motor to start. The micro switch 8 is located on the outside of the fixing plate 2.

[0044] Therefore, when the winding becomes slack, cable 13 loosens, reducing the tension on detection spring 9. Under the pushing force of detection spring 9, cable 13 moves away from the contact plate of microswitch 8. Detection spring 9 extends, pushing guide rod 12 away from the contact plate of microswitch 8. At this time, microswitch 8 sends a signal to the electrical control system. Upon receiving the signal, the control system stops the motor to prevent further slack in the winding. Conversely, when cable 13 tightens, the increased tension causes guide rod 12 to press against microswitch 8, triggering the control system to restart the motor and continue winding. At this time, guide rod 12 simultaneously applies pressure to detection spring 9 to continue monitoring the winding tightness.

[0045] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0047] This invention comprehensively solves the shortcomings of existing winding devices, such as excessive reliance on manual labor, cable loosening and damage due to the inability to monitor cable pressure, and high dependence on motors for reciprocating winding. By automatically reciprocating cable routing, real-time monitoring of winding tension, and the use of only ordinary geared motors, it effectively achieves the stability, accuracy, and safety of winding, saves manpower, and provides great convenience for cable fault detection, thus possessing good market value.
