Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cable accessories, in particular to an intelligent inspection device for rubber parts of cable accessories. Background Art
[0002] Cable accessories are products that connect cables to power transmission and distribution lines and related power distribution devices. They generally refer to the intermediate and terminal connections of various cables in the cable lines. Together with the cables, they form a power transmission network. Cable accessories are mainly based on the characteristics of the cable structure. They can not only restore the performance of the cable, but also ensure the extension of the cable length and the connection of the terminal. The production process of cable accessories is more stringent than that of cables. They need to be produced and formed in a clean workshop environment, and the various inspection requirements during the forming process are also very high.
[0003] The outdoor terminals and GIS terminals used in high-voltage cable accessories of 110kV and above are made of liquid silicone rubber injection molding or EPDM rubber injection molding. For liquid silicone rubber products, some manufacturers use gray liquid silicone rubber, while some manufacturers use transparent liquid silicone rubber.
[0004] The advantage of using transparent liquid silicone rubber is that it is convenient for inspectors to visually inspect defects in the product, such as impurities, bubbles, incomplete vulcanization, etc., through appearance or under light. However, in addition to inspecting the outside of the rubber parts, it is also necessary to inspect the internal length and defects at the transition joint between the insulating silicone rubber and the semi-conductive silicone rubber. Traditional inspection methods are obviously unable to meet these requirements, and the equipment is exposed to the outside for a long time, with limited use and short service life. Summary of the invention
[0005] The technical problem to be solved by the present invention is that the current detection method cannot accurately measure the internal size and length of the product, whether the transition joint between the insulating silicone rubber and the semi-conductive silicone rubber is lacking in glue, over-glueized, or the overlap is uneven, and the equipment is exposed to the outside for a long time, with limited use and short service life.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Figure 1 , Figure 2 , Figure 3 and Figure 4 The intelligent inspection device for rubber parts of cable accessories shown in the figure includes a working platform 1 and a display component 5. The upper surface of the working platform 1 is provided with a top telescopic opening, and an electrically controlled lifting switching platform 2 is slidably assembled inside the top telescopic opening. The upper surface of the electrically controlled lifting switching platform 2 is installed with an electrically controlled rolling support component 3 and an electrically controlled translation detection component 4.
[0025] The display assembly 5 is fixedly mounted on one side of the upper surface of the working platform 1 .
[0026] In order to facilitate assembly, an upper opening of the top telescopic opening is provided with an upper sinking groove 6 for improving the stability of the electrically controlled lifting switching platform 2 , and lateral control grooves 7 are provided on both side walls of the upper sinking groove 6 .
[0027] In order to cooperate with lifting adjustment and flipping, the electrically controlled lifting switching platform 2 includes an internal lift 21 fixed inside the lateral control slot 7, a top mounting seat 22 fixed on the top telescopic rod of the internal lift 21, and a top flip support plate 23 movably assembled with the top mounting seat 22.
[0028] In order to cooperate with the flip adjustment, a lateral mounting groove 24 with an opening on one side is opened inside the top flip support plate 23, and sunken mounting slots are provided at the upper and lower opening positions of the lateral mounting groove 24. The top supporting closing cover plate 25 is clamped and fixed inside the sunken mounting slot at the upper end of the lateral mounting groove 24.
[0029] The internal elevator 21 controls the top mounting seat 22 to be raised and lowered by telescoping, and then controls the top flip support plate 23 to be lifted and flipped, so that the detection equipment can be flipped from the bottom to the top. Then the internal elevator 21 inserts the top flip support plate 23 into the sunken mounting slot by contracting.
[0030] In order to cooperate with the electrically controlled translation adjustment, the electrically controlled rolling support assembly 3 includes an embedded translation guide rail 31 fixed on the upper surface of the top flip support plate 23, a first electrically controlled screw rod 32 installed inside the embedded translation guide rail 31, a first internally threaded translation block 33 threadedly sleeved on the first electrically controlled screw rod 32, a top support frame 34 fixedly installed on the first internally threaded translation block 33, and an electrically controlled support roller 35 movably installed inside the top support frame 34.
[0031] The first electrically-controlled lead screw 32 drives the first internally-threaded translation blocks 33 on both sides to translate along the embedded translation guide rail 31 by rotating, thereby changing the distance between the top support frame 34 and the electrically-controlled support roller 35 on both sides, thereby changing the height of the cable accessory rubber part supported on the electrically-controlled support roller 35.
[0032] In order to cooperate with the translation adjustment, the electrically controlled translation detection component 4 includes an overhead translation guide rail 41 fixedly mounted on the upper surface of the top flip support plate 23, an electrically controlled translation seat 42 slidably mounted on the overhead translation guide rail 41, and a liftable horizontal bracket 43 mounted on the side wall of the electrically controlled translation seat 42. The left end of the liftable horizontal bracket 43 is fixedly equipped with an optical detection probe 8.
[0033] The optical detection probe 8 is a high-definition detection camera, which is used to watch, shoot, and scan the internal conditions of the rubber parts of the cable accessories in real time, and then transmit the captured conditions to the display component 5. The display component 5, that is, the liquid crystal display, facilitates the detection personnel to zoom in for close observation.
[0034] The electrically controlled translation seat 42 translates along the top translation guide rail 41 on the upper surface of the top flip support plate 23 , thereby inserting the liftable transverse bracket 43 into or under the cable accessory rubber member.
[0035] In order to increase the light intensity during the detection process and improve the detection effect, the upper surface of the top flip support plate 23 located on one side of the top support frame 34 and the end of the liftable horizontal bracket 43 located on the outside of the optical detection probe 8 are fixedly equipped with LED lights 9 for fill light.
[0036] Function ① Detect product internal dimensions, inner wall appearance, transition overlap, etc. The cable accessory rubber part rotates at a constant speed driven by the drum, and the detection unit moves forward at a constant speed driven by the motor. When the detection unit reaches the position of the cable accessory rubber part, the LED light 9 and the optical detection probe 8 are automatically turned on for detection. The cable accessory rubber part is rotating, and the optical detection probe 8 can automatically convert the point-like camera image into a planar product internal structure, display it on the screen of the display component 5, and automatically calculate the size of the product. When the detection unit completely moves inside the cable accessory rubber part, it stops shooting and returns to its original position. Through the plan view displayed on the screen of the display component 5, the internal size data can be obtained to see whether the overlap of the insulating silicone rubber and the semi-conductive silicone rubber is flat. Function ② detects impurities, bubbles, and uncured conditions inside the product. When the cable accessory rubber part rotates at a constant speed driven by the rotating drum, the optical detection probe 8 moves forward at a constant speed driven by the motor. When the optical detection probe 8 reaches the bottom of the cable accessory rubber part, the annular LED light around the detection unit goes out, and the long LED light strip at the bottom of the cable accessory rubber part lights up, providing an upward light source. Since the insulating silicone rubber of the cable accessory rubber part is transparent, impurities, bubbles and other abnormal conditions inside can be captured by the optical detection probe 8. The cable accessory rubber part is rotating, and the optical detection probe 8 can automatically convert the point-like video into a planar internal structure of the product, display it on the screen of the display component 5, and automatically analyze and detect abnormal points. When the optical detection probe 8 has completely walked through the interior of the cable accessory rubber part, it stops filming and returns to its original position.
[0037] In order to cooperate with the electric control translation and optical positioning, the electric control translation seat 42 includes a sliding base 421 whose bottom is slidably sleeved on the top translation guide rail 41, a main box body 422 fixed on the sliding base 421, an electric drive wheel 423 installed at the lower end of the main box body 422, and an optical positioning control module 424 fixed on the periphery of the connecting end of the liftable horizontal bracket 43.
[0038] The bottom of the electric drive wheel 423 contacts the upper surface of the top flip support plate 23 , and the electric drive wheel 423 drives the sliding base 421 and the main box body 422 to translate along the top translation guide rail 41 by rotating.
[0039] Built-in lifting screws for controlling the liftable transverse bracket 43 are installed on the inner walls on both sides of the main box body 422. The liftable transverse bracket 43 is adjusted to rise and fall by an internally threaded lifting seat sleeve of an integrated structure on the built-in lifting screws.
[0040] Optical positioning control modules 424 are fixed on the upper and lower ends of the lifting and lowering cross-bracket 43, which can monitor the upper and lower ends of the lifting and lowering cross-bracket 43 respectively, so that the lifting and lowering cross-bracket 43 can be smoothly inserted under and inside the cable accessory rubber part.
[0041] The optical positioning control module 424 detects the distance optically in the lateral direction, thereby determining the relative position of the rubber member of the cable accessory.
[0042] When it is necessary to inspect the outside of the cable accessory rubber part, it is only necessary to control the cable accessory rubber part to be lifted and the liftable transverse bracket 43 to be lowered until the optical positioning control module 424 cannot detect the cable accessory rubber part, and then translate the liftable transverse bracket 43 to the bottom of the cable accessory rubber part, and then drive the cable accessory rubber part to rotate through the electrically controlled support roller 35. At this time, the optical detection probe 8 performs optical detection on the outer wall of the rolling cable accessory rubber part; when it is necessary to inspect the inside of the cable accessory rubber part, it is only necessary to control the cable accessory rubber part to be lowered and the liftable transverse bracket 43 to be lifted until the optical positioning control module 424 cannot detect the cable accessory rubber part, and then translate the liftable transverse bracket 43 to the inside of the cable accessory rubber part, and then drive the cable accessory rubber part to rotate through the electrically controlled support roller 35. At this time, the optical detection probe 8 performs optical detection on the inner wall of the rolling cable accessory rubber part.
[0043] In order to improve the shock-absorbing effect of the internal supporting surface, a shock-absorbing rubber pad is fixedly mounted on the inner bottom surface of the upper sinking groove 6.
[0044] In order to cooperate with the electric control lifting and adjustment, an embedded longitudinal guide rail 10 is fixedly installed on the side wall of the working platform 1, and an embedded lifting screw rod 11 is movably installed inside the embedded longitudinal guide rail 10. The outer thread of the embedded lifting screw rod 11 is threadedly sleeved with an internal thread lifting seat 12, and the outer side of the internal thread lifting seat 12 is elastically and movably equipped with a flip support panel 13.
[0045] The embedded lifting screw 11 is rotated and adjusted through the control panel installed on the side wall of the working platform 1, and then the internal thread lifting seat 12 is driven to lift and lower along the embedded longitudinal guide rail 10, so that the cable accessory rubber parts are transported by using the flip support panel 13. The internal thread lifting seat 12 is symmetrically provided with lateral assembly grooves for movably assembling the flip support panel 13 on both sides of the assembly end of the embedded lifting screw 11. The flip support panel 13 is inserted into the lateral assembly groove through the connecting end bracket and movably assembled with the internal thread lifting seat 12. An external reset spring piece for controlling the elastic flipping and reset of the flip support panel 13 is fixed on the outer side surface of the internal thread lifting seat 12.
