Description

Technical Field

[0001] The invention relates to the technical field of cable quality detection, and in particular to a device and method for detecting the wear resistance of an insulated smooth aluminum sheathed cable. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. The cable is wrapped with an insulating layer made of non-conductive insulating material to prevent the internal wires from contacting the outside world and causing accidents such as leakage and electric shock.

[0004] At present, there is a 500kV high-voltage cross-linked polyethylene insulated smooth aluminum sheathed cable, which may inevitably have relative friction with external substances during use. In order to ensure the safety of the cable during use, it is necessary to perform a wear resistance test on the insulation layer of the cable during the production process of the cable. The existing devices for testing the wear resistance of the cable can generally only simply simulate a single external friction environment. For example, friction detection of the cable insulation layer is performed by moving a reciprocating sliding friction component, and the friction data cannot be displayed intuitively. The wear resistance of the cable is judged by visual observation and hand touch, and the simulation of the friction environment to which the cable is subjected during actual use is not comprehensive enough.

[0005] In actual environment, the external frictions of 500kV high voltage cross-linked polyethylene insulated smooth aluminum sheathed cable include sliding friction and rotational friction around the cable. Therefore, a single friction environment simulation test cannot fully reflect the wear resistance of the cable insulation layer, which affects the judgment of the wear condition of the cable insulation layer in the actual use environment and whether the wear resistance of the cable insulation layer is qualified, resulting in large detection errors. Summary of the invention

[0006] In view of the above problems, the present invention proposes a device and method for detecting the wear resistance of an insulated smooth aluminum sheathed cable, which continuously changes the friction direction while performing reciprocating friction, thereby simulating a variety of friction environments, which is more in line with the actual situation of cable wear during use, can reduce the error in cable wear resistance detection, and the detection results can be displayed intuitively.

[0016] The third aspect of the present invention provides a method for detecting the wear resistance of an insulated smooth aluminum sheathed cable. The insulated smooth aluminum sheathed cable wear resistance detection device based on the first aspect of the present invention comprises the following steps: S1: Manually operate the clamping mechanisms at both ends of the detection device to open the arc-shaped pressure wheels, and insert the smooth aluminum sheathed cable to be tested into the wire holes in the center of the three-claw plate, the second support and the third support of the lathe, and manually operate the clamping mechanisms at both ends of the detection device again to clamp the arc-shaped pressure wheels to clamp the smooth aluminum sheathed cable to be tested; S2: The control system controls the first motor to start and drive the first lead screw to rotate, and drives the detection mechanism to slide on the slideway of the bottom plate through the lead screw sleeve on the second support meshing with the first lead screw, and moves the detection mechanism to the test position, and uses the laser sensor to detect the surface data of the unrubbed cable, and uploads the detected data to the control system in real time for storage, and drives the detection mechanism to leave the test position through the first motor; S3: The control system controls the second motor to rotate and drive the second lead screw to rotate, and drives the test mechanism to slide on the slideway of the bottom plate through the slider at the bottom of the third support to the test position through the lead screw sleeve on the third support meshing with the second lead screw. The control system controls the multiple cylinders on the third support to start, drive the friction block to press the cable, and measure the pressing force of the friction block through the weighing force sensor. The pressure information is transmitted to the control system through the sensor line. When the pressure information is equal to the pressure value set by the system, the cylinder stops pressing down, and the test mechanism is reciprocated and rubbed on the tested cable through the forward and reverse rotation of the second motor, and the large gear ring is driven to rotate by the third motor, and then the cable pressed by the arc pressure wheel is driven to rotate together through the three-claw disk of the lathe connected to the large gear ring, so as to change the friction direction; S4: When the friction reaches the test requirement, the second motor stops running, the cylinder drives the friction block to loosen the cable, and the test mechanism is moved away from the test position. The first motor starts to drive the first lead screw to rotate, and the lead screw sleeve on the second support meshing with the first lead screw drives the detection mechanism to slide on the slideway of the bottom plate through the slider at the bottom of the second support, and the detection mechanism is moved to the test position. The laser sensor is used to detect the surface data of the rubbed cable, and the detected data is uploaded to the control system in real time for storage; S5: retrieve the data of the two frictions for analysis. When the result after friction meets the wear resistance requirement, the smooth aluminum sheathed cable under test is qualified. When the result after friction does not meet the wear resistance requirement, the smooth aluminum sheathed cable under test is unqualified and an alarm signal is issued.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The wear resistance detection device and detection method of the insulated smooth aluminum sheathed cable of the present invention sequentially passes the smooth aluminum sheathed cable to be tested through the arc pressure wheels of the left end clamping mechanism and the right end clamping mechanism. At this time, the smooth aluminum sheathed cable to be tested can pass through the test mechanism and the detection mechanism. Under the pressing action of the 6 cylinders on the test mechanism, the 6 friction blocks are radially in contact with the outer surface of the circumference of the smooth aluminum sheathed cable to be tested. By controlling the reciprocating movement of the test mechanism, the friction blocks and the cable surface are repeatedly rubbed. Combined with the overall rotation of the three-claw disk of the lathe, the friction direction is continuously changed while the reciprocating movement is rubbed, and the simulation of various friction environments is realized. The smooth aluminum sheathed cable to be tested is tested for the first time and the last time by a 3D laser sensor, and the data before and after friction are obtained and analyzed, so as to determine whether the wear resistance of the smooth aluminum sheathed cable to be tested is qualified. The detection device of the present invention is more in line with the actual situation of cable wear and tear, and can reduce the error in the detection of cable wear resistance. The entire test process is automated, easy to operate, and the detection efficiency is greatly improved.

[0018] The insulated smooth aluminum sheath cable wear resistance detection device and detection method of the present invention adopt advanced weighing force measuring sensor and detection module technology to streamline the entire test process, realize automatic operation of wear resistance detection, improve detection flexibility and operational convenience, reduce the operator's workload, have a fast detection speed, and can obtain detection results in a short time, so that non-professionals can also easily get started, reduce the difficulty of operation, and greatly improve the detection efficiency; adopt all-round and dead-angle-free high-precision detection technology and sensors to expand the detection range, reduce the error in cable wear resistance detection, ensure the accuracy of the detection results, and be able to monitor in real time whether the cable wear condition meets the process requirements; reduce the errors and uncertainties in traditional detection methods, provide strong support for cable manufacturing; and provide more reliable guarantees for the safe operation of cables.
