It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0025] Please also read Figures 1 to 4 The cable detection device provided by the utility model is now described. The cable detection device includes a pay-off frame 1, a wire feeding frame 2, a bead chain detection assembly 3, a pressure roller detection assembly 4 and a traction plate 7 which are arranged in sequence. The bead chain detection assembly 3 includes a box body 31 and a bead chain 32 arranged in the box body 31. The bead chain 32 is connected to the top wall of the box body 31 and extends downward. The bead chain 32 can contact with the cable core and be electrically conductive. The pressure roller detection assembly 4 includes a wire barrel 41 and an elastic pressure roller connected to the inner peripheral wall of the wire barrel 41. The elastic pressure roller presses on the surface of the cable and can be electrically conductive with the cable core.

[0026] Compared with the prior art, the cable detection equipment provided by the present embodiment can pull the cable through the frame, and the wire feeding frame 2 can effectively guide the cable. The surface damage of the cable is detected in turn by using the bead chain detection component 3 and the pressure roller detection component 4. If the bead chain 32 contacts the cable core, it is preliminarily determined that the cable at this position is damaged. If no damage is detected, the cable will also contact the elastic pressure roller, and the elastic pressure roller elastically presses on different positions of the cable wall to comprehensively detect its damage state, thereby improving the detection accuracy and ensuring the quality of the cable.

[0027] In this embodiment, the bead chain 32 and the elastic roller are both made of conductive materials, and both are powered on during testing. When the cable is damaged and the core is exposed, the core of the cable can contact the bead chain 32 or the elastic roller to achieve a point conduction effect. At this time, the damage of a specific part of the cable can be judged according to the electrical conduction.

[0028] In one possible implementation, see Figures 1 to 4 The traction disk 7 is connected to a driver, and the cable detection equipment also includes a controller and a first current sensor and a second current sensor electrically connected to the controller respectively. The first current sensor can be electrically connected to the bead chain 32 to generate a first conduction signal and send the first conduction signal to the controller. The second current sensor can be electrically connected to the elastic pressure roller to generate a second conduction signal and send the second conduction signal to the controller. The controller is used to send a stop command to the driver.

[0029] In this embodiment, the electrical conductivity between the bead chain 32 and the cable core is monitored by the first current sensor. When the bead chain 32 and the cable core are in contact and electrically conductive, the first current sensor can generate a first conduction signal and send it to the controller. The controller determines that the part of the cable is damaged according to a preset program, and the driver sends a stop command. The driver stops moving, and the traction disk 7 stops pulling the cable, so as to facilitate repair of the damaged part of the cable to ensure the product quality of the cable.

[0030] In one possible implementation, see Figures 1 to 4 The box 31 extends along the direction of the cable, and several groups of bead chains 32 are arranged at intervals along the extension direction of the box 31. Each group of bead chains 32 includes several bead chains 32 arranged at intervals along the width direction of the box 31, and two adjacent groups of bead chains 32 are arranged in a staggered manner. The box 31 is a rectangular box 31, extending a certain length along the direction of the cable. Multiple groups of bead chains 32 are convenient for increasing the probability of contact with the surrounding wall of the cable and improving the detection accuracy. Two adjacent groups of bead chains 32 are arranged in a staggered manner, that is, staggered in the width direction of the box 31, which can also increase the detection probability and ensure effective detection of the cable.

[0031] For some examples, see Figures 1 to 4 The bead chain 32 includes a plurality of connecting bars 33 and connecting balls 34 connected in sequence. The connecting bars 33 and the connecting balls 34 are arranged at intervals. The outer diameter of the connecting balls 34 is larger than the outer diameter of the connecting bars 33. The connecting balls 34 and the connecting bars 33 are respectively conductive components used to contact the cable core so that the first current sensor generates a first conduction signal.

[0032] In this embodiment, the bead chain 32 is in the form of a combination of a connecting strip 33 and a connecting ball 34, so that the bead chain 32 has a certain flexibility and can swing vertically, which can effectively avoid blocking the cable movement process, reduce the resistance of the cable travel, and improve the fluency of detection.

[0033] In one possible implementation, see Figures 1 to 4 A plurality of mounting grooves 43 are provided on the inner wall of the wire drum 41, and an elastic pressure roller is connected to the inner wall of the mounting groove 43. The elastic pressure roller is arranged to protrude from the inner wall of the wire drum 41 toward the axial side of the wire drum 41, and the elastic pressure roller can be pressed against the outer wall of the cable core to enable the second current sensor to generate a second conduction signal.

[0034] In this embodiment, the elastic pressure roller is protruding toward the axial side of the wire drum 41, and can roll with the peripheral wall of the cable, which not only ensures the smooth movement of the cable, but also achieves effective contact with the peripheral wall of the cable, making it easy to detect the damaged part of the cable through the elastic pressure roller.

[0035] For some examples, see Figures 1 to 4 The elastic pressure roller includes an elastic member 44 connected to the inner bottom wall of the mounting groove 43, a pressing block 46 connected to the outer end of the elastic member 44, and a pressing roller 45 rotatably connected to the pressing block 46, and the pressing roller 45 is used to press against the peripheral wall of the cable or the cable core. The elastic member 44 has the effect of elastically pushing the pressing block 46 toward the axial side of the wire barrel 41, so that the pressing roller 45 on the pressing block 46 can fully contact with the peripheral wall of the cable, ensuring effective detection of different positions on the periphery of the cable.

[0036] For some examples, see Figures 1 to 4 A mounting shaft frame 47 is provided on the side of the pressing block 46 away from the elastic member 44. The mounting shaft frame 47 has a wheel shaft 42 that penetrates the pressing roller 45. The pressing roller 45 is rotatably connected to the outer periphery of the wheel shaft 42. Slide bars 49 are also provided on both sides of the pressing block 46. Slide grooves 48 are correspondingly provided on the two side walls of the installation groove 43. The slide bars 49 are slidably connected in the slide grooves 48 to limit the sliding direction of the pressing block 46, thereby ensuring the reliable installation of the pressing roller 45. The mounting shaft frame 47, the pressing block 46, the wheel shaft 42 and the pressing roller 45 are all conductive material components, and the second current sensor and the pressing block 46 can be electrically conductive.

[0037] In one possible implementation, see Figures 1 to 4 The wire feeding frame 2 is provided with a proximity switch 21 electrically connected to the controller, and the wire feeding frame 2 is rotatably connected with a broken wire balance wheel 22, which is rotatably connected to the wire feeding frame 2 through a rotating shaft 23, and a radially extending pendulum rod 24 is connected to the outer periphery of the rotating shaft 23. The broken wire balance wheel 22 is located above the cable and rolls with the peripheral wall of the cable. The pendulum rod 24 can swing downward and approach the proximity switch 21 following the broken wire balance wheel 22 when the cable breaks. The controller is used to receive the proximity information of the proximity switch 21 and send a stop command to the driver.

[0038] In this embodiment, the broken wire balance wheel 22 is fixedly connected to the rotating shaft 23, and the rotating shaft 23 is rotatably connected to the wire feeding frame 2. The broken wire balance wheel 22 can be pressed against the top of the cable, and the peripheral wall of the broken wire balance wheel 22 is provided with an arc groove in contact with the peripheral wall of the cable. When the wire breaks, the broken wire balance wheel 22 loses the supporting effect of the peripheral wall of the cable and swings downward, thereby driving the pendulum rod 24 to swing toward the side of the proximity switch 21. When the proximity switch 21 detects the pendulum rod 24, it can generate proximity information and send the above proximity information to the controller. The controller determines that the cable is in a disconnected state according to the preset program, and can send a stop command to the driver, and the driver stops rotating, which is convenient for the operator to perform subsequent processing.

[0039] For some examples, see Figures 1 to 4 The wire feeding frame 2 is provided with a transverse guide wheel group 5 for guiding the cable. The transverse guide wheel group 5 is located on the side of the broken wire balance wheel 22 away from the bead chain detection component 3. The transverse guide wheel group 5 includes two transverse rollers 51 extending in the horizontal direction respectively. A first gap for the cable to pass through is formed between the two transverse rollers 51. The cable passes through the first gap, and the longitudinal position of the cable is effectively limited to avoid up and down jumping of the cable during operation, thereby ensuring the accuracy of detection.

[0040] For some examples, see Figures 1 to 4 The wire feeding frame 2 is provided with a longitudinal guide wheel group 6 for guiding the cable. The longitudinal guide wheel group 6 is located on the side of the transverse guide wheel group 5 away from the wire breaking balance wheel 22. The longitudinal guide wheel group 6 includes two longitudinal rollers 61 extending in the up and down directions respectively, and a second gap for the cable to pass through is formed between the two longitudinal rollers 61. The second gap for the cable to pass through is formed between the two longitudinal rollers 61. The cable passes through the second gap, and the lateral position of the cable is effectively limited, avoiding the situation of left and right jumping during the operation of the cable, and ensuring the accuracy of the detection.

[0041] The above-mentioned cable detection equipment pulls the cable through the frame. After the wire feeding frame 2 guides the cable to the bead chain detection component 3, the surface damage of the cable is detected in turn by using the bead chain 32 and the pressure roller detection component 4. If the bead chain 32 contacts the cable core, it is preliminarily determined that the cable at this position is damaged. If no damage is detected, the cable will also contact the elastic pressure roller, and the elastic pressure roller elastically presses on different positions of the cable wall to comprehensively detect its damage status, thereby improving the detection accuracy and ensuring the quality of the cable.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
