Description

Technical Field

[0001] This utility model relates to the field of cables, and in particular to a cable reel protection device. Background Technology

[0002] In existing technologies, cable reels are widely used in automation projects for cable winding and unwinding operations. However, existing cable reels have the following problems during use: 1. Cables are easily broken due to excessive tension; 2. The winding speed and the cable movement speed are inconsistent, resulting in the cable being either slack or excessively taut; 3. Cables in the same trench become entangled due to uncoordinated movement. These problems not only affect the normal operation of equipment, but may also cause cable damage and safety accidents. Therefore, there is an urgent need for a protective device that can monitor the stress state of cables in real time and automatically adjust accordingly. Utility Model Content

[0003] This application provides a cable reel protection device that solves the problems in the prior art where cables are easily broken due to excessive tension; the reel speed and the cable movement speed are inconsistent, resulting in the cable being either slack or overly tight; and cables in the same trench become entangled due to uncoordinated movement. The technical solutions adopted in the embodiments of this application are as follows.

[0004] A cable reel protection device includes a torque sensor, a feedback control system, a motor speed control module, and an alarm system. The torque sensor is installed at the bottom of the cable tray to detect the cable's stress in real time. The feedback control system is connected to the torque sensor and feeds back the detected values ​​to the cable reel motor and the alarm system. The motor speed control module is connected to the feedback control system and dynamically adjusts the cable reel motor's speed based on the torque sensor feedback signal transmitted by the feedback control system. The alarm system is connected to the feedback control system and triggers an alarm when the cable stress exceeds a maximum tensile force threshold.

[0005] As a further improvement to the above technical solution: the number of torque sensors is two, which are symmetrically installed at the bottom of the cable tray.

[0006] As a further improvement to the above technical solution: the feedback control system has a built-in signal processing unit for processing the signals transmitted by the torque sensor and generating motor speed adjustment commands and alarm trigger commands.

[0007] As a further improvement to the above technical solution: the alarm system includes an audible and visual alarm module, which is used to emit sound and light signals to alert the operator.

[0008] As a further improvement to the above technical solution: the motor speed control module adopts a frequency conversion speed control method to achieve precise adjustment of the speed of the cable reel motor.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. By employing two torque sensors symmetrically installed at the bottom of the cable tray, subtle changes in cable stress can be accurately captured. The feedback control system processes the sensor data in real time and precisely adjusts the motor speed via frequency conversion speed regulation to ensure synchronization between the winding speed and the cable movement speed. This completely solves the problem of slack or excessive tightness caused by speed mismatch in traditional cable reels, extending cable lifespan. When the cable stress exceeds a preset threshold, the alarm system immediately triggers an audible and visual alarm. Simultaneously, the feedback control system automatically adjusts the motor speed or stops the machine to prevent the cable from breaking due to excessive tension, effectively reducing the risk of equipment damage and safety accidents, and ensuring production continuity. The built-in signal processing unit filters and amplifies the sensor data, improving signal accuracy and anti-interference capabilities, ensuring rapid response and accurate judgment of the control system. Even under complex working conditions, it can reliably achieve motor speed regulation and alarm triggering, improving the stability and reliability of the device. The dynamic speed regulation function significantly improves the coordination of cable movement in the same trench, avoiding entanglement caused by speed differences. It reduces manual intervention, lowers maintenance costs, and improves cable winding and unwinding efficiency, making it particularly suitable for complex automated scenarios with multiple cables running in parallel.
