Description

Technical Field

[0001] The invention relates to the technical field of cable puncture, and in particular to an automatic cable puncture device. Background Art

[0002] In the power transmission and distribution network, cable piercing is used to connect high-voltage or low-voltage cables to achieve effective power transmission. Before the high-voltage cable is cut, it is necessary to ensure that the cable is effectively grounded and pierce the cable copper core to ensure that the cable is not energized in preparation for the subsequent cutting operation.

[0003] At present, the cable puncture technology mainly relies on manual puncture. During the puncture process, the worker holds a solid grounded puncture tool, hammers the puncture nail with a hammer, and visually determines whether the nail hits the copper core. Once the nail hits the live cable, it is very easy to affect personal safety. Such accidents are common in power production.

[0004] In addition, the existing technology usually adopts the following methods to perform cable puncture: first, an automatic puncture scheme using rotary drilling technology. If this scheme drills into a live cable, unsafe phenomena such as the working motor directly contacting high voltage electricity and violent discharge on the contact surface may occur, so it has not been promoted and applied; second, puncture is performed by firing nails, etc., because the puncture surface is small, the puncture effect cannot be seen, and it is impossible to judge whether the puncture is in place (whether the copper core is nailed), and due to the limitation of the operation method, the puncture process cannot ensure the normal use and full grounding of the grounding wire required by the power safety work regulations. Puncture into a live cable may cause cable explosion and other phenomena; third, a drilling rig is used to drill a hole below the cable armor, and the electric field is measured to determine whether the cable is charged to prevent direct puncture of the live cable. This method may not be obvious due to the small drilling surface, and the electric field is complex in a multi-cable mixed channel, so it is often impossible to correctly judge. High-voltage equipment operations often do not allow for fault tolerance, so this method is not practical.

[0005] Therefore, the key to cable puncture is to successfully achieve puncture and obtain reliable judgment, while ensuring that personal and equipment safety can be effectively protected when puncture occurs on live cables. Summary of the invention

[0031] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0032] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 5As shown, an automatic cable puncture device includes: a clamping mechanism 1, a puncture head 2, a hydraulic cylinder 3, a control system 4 and an in-place detection mechanism 5.

[0033] The clamping mechanism 1 is used to stably and reliably clamp the cable 6, and it can be adjusted accordingly according to the size of the cable 6. The clamping mechanism 1 includes a first support frame 11, a second support frame 12, a guide block 13, a baffle plate 16, etc. The first support frame 11 is arranged opposite to the second support frame 12, one end of the guide block 13 is fixedly connected to the first support frame 11, and the other end of the guide block 13 is slidably connected to the second support frame 12. Therefore, when the guide block 13 and the first support frame 11 slide synchronously relative to the second support frame 12, the size of the space between the first support frame 11 and the second support frame 12 can be adjusted, and the space formed between the first support frame 11 and the second support frame 12 is the space for clamping the cable 6, so the adjustment can adapt to the clamping requirements of cables 6 of different sizes. In addition, the second support frame 12 is provided with a locking member that locks the positions of the two when the guide block 13 slides to a specified position relative to the second support frame 12. In this embodiment, the first support frame 11 and the second support frame 12 are both arc-shaped and symmetrically arranged. Two first support frames 11 and two second support frames 12 are respectively provided. The two first support frames 11 are stacked to form a gap, and the two second support frames 12 are stacked to form a gap, then one end of the guide block 13 is clamped between the two first support frames 11, and the other end of the guide block 13 is loaded between the two second support frames 12. The first support frame 11 is provided with a plurality of fastening bolts 17, through which the two first support frames 11 can be fixedly connected or the two first support frames 11 and the guide block 13 can be fixedly connected. The second support frame 12 is provided with a plurality of hand-tightening bolts 18, through which the two second support frames 12 can be fixedly connected and used as locking members. At the same time, two guide blocks 13 are also provided, one guide block 13 is provided between the first end of the first support frame 11 and the first end of the second support frame 12, and the other guide block 13 is provided between the second end of the first support frame 11 and the second end of the second support frame 12. Thus, the first support frame 11, the guide block 13 and the second support frame 12 can enclose a closed space to clamp the cable 6. A first one-way rack 14 is arranged on the guide block 13, and a second one-way rack 15 matched with the first one-way rack 14 is arranged on the second support frame 12. The guide block 13 and the second support frame 12 are connected through the first one-way rack 14 and the second one-way rack 15, so as to facilitate the adjustment of the guide block 13 and the second support frame 12 to move toward each other.The baffle plate 16 is arranged in the space between the first support frame 11 and the second support frame 12, and is connected to the first support frame 11. The two ends of the baffle plate 16 are bent and fixedly connected to the first support frame 11 by installing bolts, and the middle part of the baffle plate 16 forms a plurality of fixed angles protruding in the direction of the cable 6, so that a space for clamping the cable 6 is formed between the second support frame 12 and the baffle plate 16, and cables 6 of different sizes can be positioned by the fixed angles. In the process of supporting and fixing the cable 6 by the baffle plate 16 and the second support frame 12, the force of the baffle plate 16 is transmitted to the second support frame 12 through the cable 6, preventing the first one-way rack 14 and the second one-way rack 15 from separating, and avoiding the connection between the second support frame 12 and the two guide blocks 13 from loosening.

[0034] Before puncturing the cable 6, insert the cable 6 into the space between the first support frame 11 and the second support frame 12, slide the second support frame 12, the first support frame 11 and the guide block 13 toward each other, slide the combination into place so that the second support frame 12 and the baffle plate 16 can clamp the cable 6, and then use the hand-tightening bolt 18 to clamp the guide block 13, and then the puncture operation can begin. When the puncture operation is completed, the distance between a pair of second support frames 12 can be increased by rotating the hand-tightening bolt 18 in the opposite direction, so that the second support frame 12 can be quickly removed and the punctured cable 6 can be taken out. The cable 6 is clamped by the cooperation of the second support frame 12, the first support frame 11 and the guide block 13, and is positioned by the baffle plate 16. On the one hand, the cable 6 can be effectively fixed and clamped, and on the other hand, cables 6 of different models and specifications can be placed to facilitate the puncture of the cable 6.

[0035] The puncture head 2 for puncturing the cable 6 is movably arranged on the clamping mechanism 1 and arranged between the first support frame 11 and the second support frame 12. The puncture head 2 includes a slide 21 and a puncture portion 22. The slide 21 is fixedly connected to the hydraulic cylinder 3, the slide 21 is slidably connected to the guide block 13, the rear end of the puncture portion 22 is connected to the slide 21, and the front end of the puncture portion 22 forms a puncture blade ("front" is defined as the direction close to the closed space between the first support frame 11 and the second support frame 12 for clamping the cable 6, corresponding to the left side in the figure; "rear" is defined as the direction away from the closed space between the first support frame 11 and the second support frame 12 for clamping the cable 6, corresponding to the right side in the figure). A guide rail 19 can be set on the inner side of the guide block 13, and the slide 21 is slidably set in the guide rail 19 to ensure the smoothness and reliability of the puncture action. The puncture blade is set to a concave arc shape, which on the one hand can increase the fitting surface between the puncture portion 22 and the cable 6, thereby smoothly cutting the insulation layer of the cable 6, reducing the resistance during the puncture process, and making the puncture smoother; on the other hand, the arc-shaped puncture blade can more accurately control the puncture depth and position, reduce damage to the internal structure of the cable 6, and ensure the safety of the conductor inside the cable 6, that is, the copper core.

[0036] The hydraulic cylinder 3 for driving the puncture head 2 to move forward or backward is arranged on the first support frame 11 of the clamping mechanism 1 and connected to the puncture head 2 ("forward movement" is defined as the puncture head 2 moving toward the direction where the cable 6 is located, corresponding to the movement to the left in the figure; "reverse movement" is defined as the puncture head 2 moving away from the direction where the cable 6 is located, corresponding to the movement to the right in the figure). When the hydraulic cylinder 3 is extended, it drives the puncture head 2 to move forward, and when the hydraulic cylinder 3 is retracted, it drives the puncture head 2 to move backward.

[0037] The control system 4 is connected to the hydraulic cylinder 3 to control the action of the hydraulic cylinder 3, specifically including: 1) according to the received puncture start signal, control the hydraulic cylinder 3 to drive the puncture head 2 to move forward. The puncture start signal comes from the operator's operation of the control system 4; 2) according to the puncture in place signal received from the 1st to the nth time, control the hydraulic cylinder 3 to drive the puncture head 2 to move in the reverse direction first and then move forward. The puncture in place signal comes from the in place detection mechanism 5. When the puncture in place signal is received for the first n times, the control system 4 controls the hydraulic cylinder 3 to drive the puncture head 2 to move in the reverse direction for a short distance and then move forward until the next puncture in place signal is received; 3) according to the puncture in place signal received for the n+1th time, control the hydraulic cylinder 3 to drive the puncture head 2 to stop moving or control the hydraulic cylinder 3 to drive the puncture head 2 to move in the reverse direction for a short distance and then stop moving. When the puncture in place signal is received for the n+1th time, the cable 6 puncture operation ends immediately or is about to end. Where n is a positive integer, which can be selected according to actual needs, and usually n takes the value of 1. When the puncture completion signal is received for the first time, it means that the puncture of the cable 6 is preliminarily confirmed, and the puncture head 2 moves in the reverse direction and then moves forward. When the puncture completion signal is received for the second time, it is confirmed that the puncture of the cable 6 is completed.

[0038] The control system 4 includes a controller, a hydraulic oil tank 41, a hydraulic pump 42, a reversing valve 43 and a hydraulic pipeline 44, wherein the components other than the controller may be external, and the controller may be arranged at a suitable position on the clamping mechanism 1. The hydraulic pump 42 and the reversing valve 43 are respectively connected to the controller for communication, so that they are controlled by the controller. The hydraulic oil tank 41, the hydraulic pump 42, the reversing valve 43 and the hydraulic cylinder 3 are sequentially connected through the hydraulic pipeline 44. The hydraulic oil tank 41 contains hydraulic oil, and can pump the hydraulic oil into the hydraulic cylinder 3 through the hydraulic pipeline 44 and the reversing valve 43 under the pumping action of the hydraulic pump 42. When the reversing valve 43 switches different directions, the oil pump pumps the hydraulic oil in the oil tank into the hydraulic cylinder 3 through different circulation directions, so that the hydraulic cylinder 3 can respectively achieve extension or retraction. An overflow pipeline 45 and an overflow valve 46 can also be arranged between the rear end of the oil pump and the oil tank. Since the hydraulic oil and the hydraulic pipeline 44 have good insulation properties and there are no electric components in the control system 4, it is ensured that no electrical accident will occur even if the live cable 6 is punctured, thereby greatly improving the safety of the operation.

[0039] The in-place detection mechanism 5 is arranged on the clamping mechanism 1, and cooperates with the transmitter 51 that transmits the detection signal into the cable 6 to send a puncture in-place signal when the puncture head 2 punctures in place. The transmitter 51 is arranged at the end of the cable 6, and its positive pole is connected to the copper core of the cable 6, so as to transmit the signal into the cable 6, and its negative pole is grounded. Preferably, the transmitter 51 is a transmitter 51 that can generate a pulse modulation signal, which loads the pulse modulation signal into the cable 6. The in-place detection mechanism 5 includes a receiver 52 mainly fixed on the clamping mechanism 1, which can receive the signal sent by the transmitter 51 from the cable 6, and output the puncture in-place signal when receiving the detection signal. The puncture head 2 is connected with a grounding wire 53, specifically, the puncture blade is connected to the grounding wire 53, that is, the puncture blade is directly grounded through the grounding wire 53, and the receiver 52 is installed on the grounding wire 53. The receiver 52 includes a current sensor, and the current signal in the cable 6 can be collected by the current sensor. The receiver 52 is connected to the controller for communication. When the puncture head 2 performs a puncture operation on the cable 6 and the puncture is in place, that is, when the puncture head 2 cuts the communication of the cable 6, the positive pole of the transmitter 51, the copper core of the cable 6, the puncture head 2, and the receiver 52 form a current signal loop, so that the receiver 52 detects the pulse modulation signal and transmits it to the controller, so that the controller controls the hydraulic cylinder 3 to perform the corresponding action. Further, the in-place detection mechanism 5 also includes an alarm based on the alarm signal. The alarm usually adopts an acoustic and / or optical alarm, which is also arranged on the clamping mechanism 1 and connected to the controller. When the controller receives the puncture in place signal, the controller sends a warning signal to the alarm to turn on the sound and / or light alarm to prompt the operator that the puncture is in place. After the controller receives the puncture in place signal for the first to nth time, the controller controls the hydraulic cylinder 3 to drive the puncture head 2 to move in the opposite direction first by controlling the reversing valve 43, and the puncture blade is separated from the copper core of the cable 6. At this time, the puncture in place signal disappears, and the sound and / or light alarm also disappears. The controller controls the hydraulic cylinder 3 to drive the puncture head 2 to move forward again through the reversing valve 43, and when the puncture is in place again, the sound and / or light alarm is issued again. The accuracy of the automatic puncture can be improved by the in-place detection mechanism 5, and the puncture is in place by repeated confirmation, avoiding the mis-sending of signals and ensuring the safety of the puncture process.

[0040] In some embodiments, the in-place detection mechanism 5 may also use a distance sensor 54 and a matching processor, such as a laser distance sensor. The distance sensor 54 is arranged on the clamping mechanism 1, and is used to detect the puncture depth of the puncture head 2. The processor is arranged at a suitable position, for example, it can be integrated in the controller of the control system 4, and is used to determine whether the puncture depth of the puncture head 2 reaches a preset depth and send a puncture in-place signal when the puncture depth of the puncture head 2 reaches the preset depth. A display interface may also be arranged on the distance sensor 54 to display the puncture depth.

[0041] The use of the above-mentioned automated cable puncture device can simplify the operating process, reduce human errors, and significantly improve the efficiency and safety performance of the cable 6 puncture operation. It has a wide range of applicability, can accurately clamp and position cables 6 of different sizes, and can achieve rapid disassembly and assembly.

[0042] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
