[0026] Example 1

[0027] In existing technologies, commonly used cable tensile testing clamps typically clamp cables manually or hydraulically. During testing, the pressure gauge must be manually observed and the clamping force controlled. For cables of different diameters, clamps need to be changed frequently, making the operation cumbersome. When clamping manually, the force is difficult to control precisely, which can easily cause damage to the cable surface or result in insecure clamping, affecting the accuracy of the cable test.

[0028] Please see Figure 1-5This utility model provides a technical solution: a cable tensile testing clamp, including a support frame 1, a housing 3 and two clamping blocks 2. The housing 3 is provided with an adjustment component 4. The two clamping blocks 2 are placed opposite each other. The outer sides of the two clamping blocks 2 are provided with a locking component 5. The opposite side of the two clamping blocks 2 is provided with anti-slip texture 9. When the cable is placed between the two clamping blocks 2, the anti-slip texture 9 increases the friction between the cable and the clamping blocks 2. A tension spring 7 is provided between the support frame 1 and the top of the clamping blocks 2. The two ends of the tension spring 7 are fixedly connected to connecting brackets 6. The two connecting brackets 6 are respectively hinged to the support frame 1 and the clamping blocks 2. When the pressing plate 46 moves up and resets, the tension spring 7 pulls the clamping blocks 2 up and resets to the highest position. Then, the position of the clamping blocks 2 is fixed by the locking component 5, waiting for the next cable tensile test. The top of the housing 3 is fixedly connected with a mounting plate, which is fixedly connected to the cable tensile testing device by bolts.

[0029] The regulating assembly 4 includes a three-phase asynchronous geared motor 41, a screw 44, a gear mechanism, two pressure sensors 47, a controller 48, and a rotating cylinder 45. The rotating cylinder 45 is rotatably connected to the top of the support frame 1 via bearings. The gear mechanism includes a driving gear 42 and a driven gear 43. The driven gear 43 is fixedly sleeved on the outside of the rotating cylinder 45. The driving gear 42 meshes with the driven gear 43, and the driving gear 42 drives the rotating cylinder 45 to rotate through the meshing driven gear 43. The three-phase asynchronous geared motor 41 is fixedly installed on one side of the housing 3. The output end of the three-phase asynchronous geared motor 41 is fixedly connected to the driving gear 42 via a rotating shaft, and the three-phase asynchronous geared motor 41 drives the driving gear 42 to rotate. The screw 44 movably passes through the rotating cylinder 45 and is connected to a pressing plate 46. The screw 44 is connected to the pressing plate 46 via a keyway. To prevent relative rotation, a bellows protective cover 8 is sleeved on the outside of the screw 44. The two ends of the bellows protective cover 8 are fixedly connected to the support frame 1 and the extrusion plate 46, respectively. The bellows protective cover 8 provides protection for the screw 44. The inside of the rotating cylinder 45 is provided with an internal thread that meshes with the screw 44. The tops of the two clamping blocks 2 are fixedly connected to guide rails 49 that are compatible with the extrusion plate 46. Pressure sensors 47 are respectively installed on the tops of the two clamping blocks 2. The controller 48 is installed on the top of the support frame 1. The pressure sensors 47 are electrically connected to the three-phase asynchronous geared motor 41 through the controller 48. When the extrusion plate 46 pushes and extrudes the two clamping blocks 2 downward to clamp the cable, if the pressure on the pressure sensor 47 is greater than the set threshold for more than 3 seconds, the three-phase asynchronous geared motor 41 is controlled to shut down.

[0030] The working principle or structural principle is as follows: the patent is fixedly installed in the cable tensile testing device by bolts. The three-phase asynchronous geared motor 41 drives the active gear 42 to rotate, which drives the meshing driven gear 43 and the rotating cylinder 45 to rotate. The internal thread of the rotating cylinder 45 causes the screw 44 to drive the extrusion plate 46 to move down along the guide rail 49, pushing the clamping block 2 to clamp the cable. The anti-slip texture 9 increases the friction. The pressure sensor 47 monitors the clamping pressure. When the pressure exceeds the threshold for 3 seconds, the controller 48 shuts off the three-phase asynchronous geared motor 41 to complete the locking. After the test, the screw 44 moves up to reset, the locking component 5 is released, the tension spring 7 pulls the clamping block 2 to reset through the connecting frame 6, the extrusion plate 46 moves up with the screw 44, the bellows protective cover 8 protects the screw 44 during the movement process, and the entire mechanism returns to the initial position to standby. The three-phase asynchronous geared motor 41 is a CLJSJ-CH02 manufactured by Kunshan Taiya Electromechanical Technology Co., Ltd., the pressure sensor 47 is an SDP810-500Pa manufactured by Shenzhen Xinwei Technology Development Co., Ltd., and the controller 48 is an XD5-32T-E manufactured by Wuxi Xinjie Electric Co., Ltd. Since the structure and operating principle of this model are existing technologies, their structure and operating principle will not be described in detail here.

[0031] Example 2

[0032] The locking assembly 5 includes two movable plates 53, which are slidably connected to the outside of the two clamping blocks 2 via slide rails 55. Several insertion holes 52 are evenly opened on both sides of the inner wall of the support frame 1. Two insertion rods 51 are fixedly connected to one side of the movable plate 53, and a pull ring 54 is fixedly connected to one side of the movable plate 53. The pull ring 54 drives the movable plate 53 to move back and forth. Two trapezoidal sliders 56 are fixedly connected to one side of each of the two clamping blocks 2. A trapezoidal groove 57 adapted to the trapezoidal sliders 56 is opened on the inner side wall of the support frame 1. The trapezoidal sliders 56 are slidably connected in the trapezoidal groove 57, so that the two clamping blocks 2 slide more stably in the support frame 1.

[0033] Working principle or structural principle: After the two clamping blocks 2 are quickly clamped by the adjusting component 4, the moving plate 53 is moved along the slide rail 55 by the pull ring 54, so that the insertion rod 51 is inserted into the insertion hole 52 of the support frame 1 and the clamping block 2 is locked in position. When the test is over and needs to be reset, the pull ring 54 drives the moving plate 53 to move outward, so that the insertion rod 51 is disengaged from the insertion hole 52. The tension spring 7 pulls the clamping block 2 upward to reset through the connecting frame 6. When the clamping block 2 reaches the highest position, the pull ring 54 is pulled again to insert the insertion rod 51 into the corresponding insertion hole 52 and fix it, so as to avoid the tension spring 7 from losing its elasticity due to long-term stretching. The tension spring 7, the driving gear 42 and the driven gear 43 are regularly inspected and maintained. When any defects are found, they are replaced in time. This equipment requires regular or irregular maintenance, and timely replacement or adjustment of corresponding parts to ensure the normal operation of the equipment.

[0034] In summary, the three-phase asynchronous geared motor 41 drives the rotating drum 45 to rotate via a gear mechanism, causing the screw 44 to drive the pressing plate 46 to push the clamping block 2 to clamp the cable. The pressure sensor 47 monitors the pressure and controls the motor's start and stop. After the test is completed, the insertion rod 51 of the locking assembly 5 disengages from the socket 52, the tension spring 7 pulls the clamping block 2 to reset, and after it is in place, the insertion rod 51 is reinserted into the socket 52 to fix it, preventing the tension spring 7 from being under long-term stress. The bellows protective cover 8 protects the movement of the screw 44, achieving efficient and reliable cable tensile testing.
