Description

Technical Field

[0001] The present invention relates to the technical field of cable insulation layer detection equipment, and in particular to a device for measuring the eccentricity and thickness of a cable insulation layer. Background Art

[0002] Most of the structures of traditional cables are divided into four components, namely a conductor, an insulation layer, a shielding layer, and a protective layer, and the protective layer is composed of a filling layer, an inner sheath, a metal armor, and an outer sheath; When cables are produced, in order to detect the thickness distribution of the insulation layer, that is, the outer sheath, a non-contact eccentricity detector is usually used to perform real-time detection on the product. This detection combines electromagnetic and optical scanning principles. The optical scanning system is used to locate the position of the insulated wire, and the electromagnetic system is used to determine the position of the conductor, so that the eccentricity can be calculated. This detection method is fast and can quickly obtain production data for subsequent production control of the insulation layer. However, since the detection of the cable by the non-contact eccentricity detector is a fixed-point detection, that is, the data of multiple points on a certain cross-section of the cable are collected, there are moving fluctuations between the data collected in real time and the actual overall data, which leads to certain detection errors in the eccentricity and thickness of the insulation layer. To eliminate this dynamic error, a device for measuring the eccentricity and thickness of a cable insulation layer is proposed. Summary of the Invention

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0018] Please refer to Figures 1-9 , a device for measuring the eccentricity and thickness of a cable insulation layer, including a non-contact eccentricity detector 1, and a following scanning mechanism 2 for tracking and scanning the detection of the cable insulation layer is provided on one side of the non-contact eccentricity detector 1; The following scanning mechanism 2 includes a detection guide rail 201, an ultrasonic detection component 3 is slidably arranged between the detection guide rails 201, the following scanning mechanism 2 further includes an adjusting component 4 arranged on one side of the non-contact eccentricity detector 1 for adjusting the working plane of the ultrasonic detection component 3, and a power component for driving the ultrasonic detection component 3 to move is arranged on the detection guide rail 201.

[0019] Most of the structures of traditional cables are divided into four components, namely a conductor, an insulation layer, a shielding layer and a protection layer. The protection layer is composed of a filling layer, an inner sheath, a metal armor and an outer sheath. When the cable is produced, in order to detect the thickness distribution of the insulation layer, that is, the outer sheath, a non-contact eccentricity detector 1 is usually used to perform real-time detection on the product. This detection combines electromagnetic and optical scanning principles. The optical scanning system is used to locate the position of the insulated wire, and the electromagnetic system is used to determine the position of the conductor, so that the eccentricity can be calculated. This detection method is fast and can quickly obtain production data for subsequent production control of the insulation layer. However, since the detection of the cable by the non-contact eccentricity detector 1 is a fixed-point detection, that is, the collection of multiple point data on a certain cross-section of the cable, such as Figure 10As shown, the non-contact eccentricity detector 1 usually collects data at four points on a certain cross-section of the cable, and calculates the eccentricity and thickness of the insulating layer by comparing the information at the four points; In order to better understand all the data of the rubber insulating layer on a certain cross-section of the cable, a following scanning mechanism 2 is added to one side of the non-contact eccentricity detector 1 in the present invention. Through the following scanning mechanism 2, the data of a certain cross-section of the cable can be fully collected. By comparing the collected data obtained by the following scanning mechanism 2 with the collected data obtained by the non-contact eccentricity detector 1, the dimension of the collected data is further supplemented, so as to more truly understand the actual situation during cable production; In the present invention, through the movement of the ultrasonic detection component 3 on the detection guide rail 201, the entire ultrasonic detection component 3 can move simultaneously with the moving cable, further enabling the ultrasonic detection component 3 to be in a relatively static state with respect to the cable. At this time, the ultrasonic detection component 3 can scan a certain cross-section of the cable to obtain relevant data. The movement of the ultrasonic detection component 3 is powered by a power component. By collecting the moving speed of the cable and then feeding it back to the power component, the same speed of the two can be achieved; In the present invention, in order to detect cables of different sizes, an automatic adjustment strategy is adopted for the setting height of the ultrasonic detection component 3. Through the adjustment component 4, not only the scanning height of the ultrasonic detection component 3 can be adjusted, but also the levelness of the detection guide rail 201 can be adjusted through the adjustment component 4, so that the moving path of the entire ultrasonic detection component 3 is relatively parallel to the moving path of the cable, thereby ensuring the stability of the data collected by the ultrasonic detection component 3. Embodiment

[0020] Please refer to Figures 5-9 , this embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. For the same parts, reference can be made to each other, and details will not be described in detail here.

[0021] As a preferred technical solution of this embodiment, the ultrasonic detection component 3 includes an arc-shaped guide plate 301 and two sliding members 302 arranged on the arc-shaped guide plate 301, and a guide strip for cooperating with the sliding member 302 is provided on the detection guide rail 201; An arc-shaped member 303 is also slidably arranged on the arc-shaped guide plate 301. A detection plate 305 is provided on the arc-shaped member 303 through a connecting rod 304. The detection plate 305 is connected with a connecting member 306 through a plurality of locking screws. The connecting member 306 is composed of a connecting head 3061 and an installation cylinder 3062, and an ultrasonic detection probe 307 is arranged in the installation cylinder 3062; A driving component for driving the arc-shaped member 303 to slide on the arc-shaped guide plate 301 is also provided on the arc-shaped member 303.

[0022] Further, the driving component includes a driving housing 308 disposed on the arc-shaped member 303. A partition plate is provided inside the driving housing 308, which divides the interior of the driving housing 308 into a power chamber and a driving chamber. A driving shaft 309 is rotatably provided inside the driving housing 308. A driving gear 310 is provided on the driving shaft 309 within the power chamber, and a worm gear 311 is provided on the driving shaft 309 within the driving chamber. A servo motor 312 is provided on the driving housing 308. The output end of the servo motor 312 is provided with a worm 313 within the driving chamber, and the worm 313 meshes with the worm gear 311. A rack for cooperating with the driving gear 310 is provided on the arc-shaped guide plate 301.

[0023] Further, the power component includes two electric telescopic rods 202 disposed on the detection guide rail 201. A pushing member 203 is provided at the telescopic end of the electric telescopic rod 202, and the pushing member 203 and the sliding member 302 are fixedly arranged through bolts.

[0024] Further, a gyroscope sensor for detecting the rotation angle of the arc-shaped member 303 in space is also provided on the driving housing 308; a linear displacement sensor for detecting the moving speed of the cable is provided on the upper housing 401.

[0025] Further, an arc-shaped reinforcing rib for enhancing stability is also provided between the detection guide rails 201.

[0026] As can be seen from the above, the specific working principle of the ultrasonic detection component 3 is as follows: When the detection axes of the two ultrasonic detection probes 307 in the ultrasonic detection component 3 are in the same plane as the cable moving axis and the two axes are perpendicular to each other, the ultrasonic detection component 3 starts to work. The linear displacement sensor provided on the upper housing 401 detects the moving speed of the cable and transmits the data to the data processor. The data processor then controls the electric telescopic rods 202 to work, further driving the pushing member 203 to move at the moving speed of the cable. Since the pushing member 203 and the sliding member 302 are fixedly arranged through bolts, the arc-shaped guide plate 301 will follow the cable to move under the drive of the two electric telescopic rods 202; The arc-shaped member 303 slidably disposed on the arc-shaped guide plate 301 rotates on the arc-shaped guide plate 301 under the drive of the drive assembly, thereby driving the detection plate 305 to rotate in the vertical plane. Since connecting members 306 are connected to both ends of the detection plate 305 and ultrasonic detection probes 307 are provided in the mounting cylinder 3062, the two ultrasonic detection probes 307 will rotate in the vertical plane. According to the set radian of the arc-shaped guide plate 301 (greater than 180°), the rotation angle of the arc-shaped member 303 can be greater than 180°. Therefore, the detection ranges of the two ultrasonic detection probes 307 are actually superimposed to 360°, that is, a full scan of a certain cross-section of the cable can be performed, and then the thickness of the insulating layer can be obtained. By processing and analyzing the data collected by the scan, the eccentricity and thickness of the insulating layer can be obtained; After the two ultrasonic detection probes 307 perform a full scan on a certain cross-section of the cable, the drive assembly is used to return the ultrasonic detection probes 307 to the initial state. The determination of this initial state and the rotation angle of the ultrasonic detection probes 307 are both sensed by the gyroscope sensor provided on the drive housing 308. At this time, the power assembly works, and the telescopic end of the electric telescopic rod 202 moves to drive the pusher 203 to reset, that is, to return the entire ultrasonic detection assembly 3 to the initial state, so as to facilitate the next full scan of a certain cross-section of the cable. Embodiment

[0027] Please refer to Figures 1-5 , this embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. For the same parts, please refer to each other and will not be elaborated here in detail.

[0028] As a preferred technical solution of this embodiment, the adjustment assembly 4 includes an upper adjustment part and a lower support part disposed on one side of the non-contact eccentricity detector 1. The upper adjustment part includes an upper housing 401 and two upper mounting shells 402 disposed on the upper housing 401. A drive shaft 403 is rotatably provided in the upper housing 401. A drive motor 404 is further provided on one side of the upper housing 401, and the output end of the drive motor 404 is fixedly provided with one end of the drive shaft 403; An adjustment screw rod 405 is rotatably provided in the mounting shell 402. One end of the adjustment screw rod 405 penetrates the upper housing 401 and a driven member 406 is provided in the upper housing 401. A driving member 407 for cooperating with the driven member 406 is provided on the drive shaft 403; An adjustment seat 408 is sleeved on the adjustment screw rod 405 through a threaded connection, and the adjustment seat 408 is hinged to one end of the detection guide rail 201.

[0029] Furthermore, the lower support portion includes two lower housings 409 disposed on one side of the non-contact eccentric detector 1. A support lead screw 410 is rotatably provided in the lower housing 409. A support seat 411 is sleeved on the support lead screw 410 through a threaded connection. A support rod 412 is rotatably provided on the support seat 411. The other end of the support rod 412 is hinged to the detection guide rail 201. An adjustment motor 413 is further provided on the lower housing 409. The output end of the adjustment motor 413 is fixedly provided with one end of the support lead screw 410.

[0030] As can be seen from the above, the adjustment of the working plane of the ultrasonic detection assembly 3 is controlled by the adjustment assembly 4. The working principle of the adjustment assembly 4 is specifically as follows: First, it is necessary to determine the detection height of the ultrasonic detection assembly 3, that is, the detection axes of the two ultrasonic detection probes 307 intersect with the central axis of the cable. The internal data processing controller sends a control signal to the drive motor 404. After the drive motor 404 works, it drives the drive shaft 403 to rotate. Through the cooperation of the follower 406 and the active member 407, the power can be transmitted to the two adjustment lead screws 405. Since the rotation of the adjustment lead screw 405 can drive the adjustment seat 408 to rise and fall, the drive motor 404 can directly adjust the height of the adjustment seat 408 after working, and then indirectly drive one end of the detection guide rail 201 to rise and fall. One end of the detection guide rail 201 is hinged to the adjustment seat 408, and the other end of the detection guide rail 201 is supported by the support rod 412, and the detection guide rail 201 and the support rod 412 are also hinged. This setting can ensure that when adjusting the height of the detection guide rail 201, it is not necessary to adjust the whole, but can be adjusted segmentally, which greatly facilitates the use of the operator. After determining the detection height of the two ultrasonic detection probes 307, it is necessary to adjust the inclination angle of the detection guide rail 201 through the lower support portion, so that the inclination angle of the detection guide rail 201 matches the inclination angle of the cable. This can ensure that the two ultrasonic detection probes 307 can always obtain a better detection position when following the cable, that is, the relatively static scanning process can ensure the stability and reliability of the collected data. The operation of the adjustment motor 413 can make the support lead screw 410 rotate, and then make the support seat 411 rise and fall in the vertical plane, thereby changing the set height of one end of the support rod 412. Since a four-bar linkage mechanism is formed among the adjustment seat 408, the detection guide rail 201, the support rod 412, and the support seat 411, changing the height of the support seat 411 can change the inclination angle of the detection guide rail 201. This adaptive change can adapt to the actual situation during actual detection, thereby increasing the expandability of the actual use of the present invention.

[0031] The control method of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common general knowledge in this field. And the present invention is mainly used to protect mechanical devices. Therefore, the control method and circuit connection of the present invention will not be further explained in detail.

[0032] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
