Description

Technical Field

[0001] This utility model relates to the field of cable tensioning technology, and in particular to a power lead tensioning device with real-time tension monitoring. Background Technology

[0002] In the past, tension monitoring relied mainly on manual inspections or handheld tension meters, a cumbersome and inefficient process that could not provide real-time monitoring. Manual inspections often failed to detect tension changes in intermediate locations of the cable, such as when the cable was being pushed up by obstacles, and could not promptly detect cable wear or damage, affecting construction safety and work efficiency. Handheld tension meters could only obtain tension values at a specific moment, and could not provide real-time tracking and early warning of tension.

[0003] The device consists of a control system, tension detection equipment, power equipment, display, and auxiliary structures. When the motor is powered on, it can automatically test the tension, and the measured tension value will be displayed on the screen. After the measurement, it can automatically reset, and the entire process is controlled by the motor.

[0004] In existing technologies, the disassembly and assembly process of some sensors is complex and requires a high level of expertise. We have simplified this process and designed a quick disassembly and assembly structure, which can be quickly installed and replaced even by novices. We have also added an automatic tension measurement device and eliminated the manual pressing device. Therefore, we have proposed a power lead tensioning device with real-time tension monitoring.

A turntable 32 is fixedly connected to the drive end of the motor 31. The turntable 32 is driven to rotate by the drive end of the motor 31. A rotating shaft 33 is fixedly connected inside the turntable 32. A connecting rod 34 is rotatably connected to the outside of the rotating shaft 33. The connecting rod 34 provides force to the sliding assembly 35 through the rotating shaft 33. The sliding assembly 35 is rotatably connected inside the connecting rod 34. The function of the sliding assembly 35 is to slide up and down, and also to fix and limit the sliding rod 352. The system includes a second rotating shaft 351, which is the connection point between the sliding assembly 35 and the rocker mechanism 3. The second rotating shaft 351 is externally rotatably connected to the bottom of the first connecting rod 34. The second rotating shaft 351 is externally fixedly connected to a bearing seat 354. The bearing seat 354 is used to fix the two sliding rods 352 and the second rotating shaft 351, making the connection between the first rod and the second shaft more secure, so that the force of the first connecting rod 34 can be transmitted to the two sliding rods 352 through the second shaft. The top of the bearing seat 354 is fixedly connected to the sliding rods 352. The two sliding rods 352 are externally slidably connected to an extension plate 353. The extension plate 353 is used to limit the two sliding rods 352 to prevent them from shifting.

[0034] Reference Figure 1 , Figure 4The extension plate 2 353 is externally fixedly connected to the inside of the extension plate 1 2. The extension plate 1 2 is used to install the motor 31 and the extension plate 2 353. The outside of the power line 7 is in contact with the bottom of the elastic support arch 48. The elastic support arch 48 is used to apply pressure to the power line 7. The tension information of the power line 7 is transmitted through the sensor 5. The support mechanism 4 includes the elastic support arch 48. The top of the elastic support arch 48 is in contact with the bottom of the sensor 5. The rear side of the turntable 32 is rotatably connected to the front side of the extension plate 1 2. The bottom of the elastic support arch 48 is set on the top of the main frame 1. The snap-on base 41 increases the friction between the protective cover 47 and the elastic support arch 48 to achieve the purpose of fixation. Multiple snap-on bases 41 are fixedly connected to the top of the elastic support arch 48. The top of the elastic support arch 48 is in contact with the bottom of the protective cover 47. The function of the two slide rods 352 is to allow the elastic support arch 48 to move. The outside of the two slide rods 352 is fixedly connected to the inside of the elastic support arch 48. Multiple cross screws 42 are used to secure multiple snap-on bases. The base 41 is fixed to the top of the elastic support arch 48. Multiple Phillips head screws 42 are externally threaded into the interior of the elastic support arch 48. The front side of the turntable 32 is slidably connected to the rear side of the connecting rod 34. Multiple snap-fit bases 41 are internally threaded with Phillips head screws 42. The interior of multiple snap-fit bases 41 is rotatably connected to the exterior of snap-fit 46. The spring 43 allows snap-fit 46 to automatically reset after use and increases the friction between snap-fit 46 and the protective cover 47. The spring 43 is internally sleeved on the connecting rod. On the outside of the second 44, springs 43 are fixedly connected inside the multiple buckle bases 41. Rotating shafts 3 45 are rotatably connected inside the multiple buckle bases 41. The multiple rotating shafts 3 45 are for enabling buckle 1 46 to rotate. Buckle 1 46 is fixedly connected to the outside of the multiple rotating shafts 3 45. Connecting rod 2 44 is fixedly connected inside the multiple buckle 1 46. The function of connecting rod 2 44 is to contact the springs 43 so that buckle 1 46 can be reset normally. A protective cover 47 is installed on the side of buckle 1 46 that is close to it.

[0035] Working principle: When the rocker mechanism 3 is working, the extension plate 2 provides power to each component through the fixed motor 31. The drive end of the motor 31 causes the fixed turntable 32 to rotate. The rotation of the turntable 32 causes the rotating shaft 33 to transmit force to drive the connecting rod 34. The connecting rod 34 is connected to the rotating shaft 351 to provide force to the sliding assembly 35. The two ends of the rotating shaft 351 are fixed by the bearing 354. The bearing 354 is fixed to the two sliding rods 352 to ensure that they will not loosen when force is applied. The two sliding rods 352 are limited by the extension plate 353 to ensure that the two sliding rods 352 will not deviate. It can maximize the sliding of the two sliding rods 352 along the fixed direction, and can capture tension changes in real time and accurately, avoiding the lag and error of manual measurement, and ensuring the timeliness and accuracy of data.

[0036] When the support mechanism 4 is working, multiple snap-fit bases 41 are connected to elastic support arches 48 via multiple cross screws 42, ensuring that the multiple snap-fit bases 41 and elastic support arches 48 are relatively fixed and will not loosen. Multiple springs 43 are fixed inside the multiple snap-fit bases 41, and the interior of the multiple snap-fit bases 41 is fixed to multiple rotating shafts 45. Multiple snap-fits 46 rotate with the multiple rotating shafts 45. Multiple connecting rods 44 are fixed on opposite sides of the multiple snap-fits 46. The multiple snap-fits 46 apply force to the protective cover 47, causing it to contact the elastic support arches 48. The protective cover 47 not only protects the sensor 5 but also fixes the sensor 5, solving the problem of difficulty in replacing the sensor 5 after damage. The sensor 5 can be easily replaced simply by removing the protective cover 47, reducing costs, ensuring monitoring at any time, and simplifying the calibration process so that ordinary maintenance personnel can operate it, reducing reliance on professional personnel, making automatic measurement easier to promote, and providing strong support for efficient monitoring and management of power lead tension.
