Description

Technical Field

[0001] This utility model relates to the technical field of cable testing devices, specifically to a visual cable testing device. Background Technology

[0002] A cable inspection device is a specialized piece of equipment used for comprehensive inspection of cable conditions. It can accurately detect the insulation performance of cables, promptly identifying potential problems such as insulation aging and damage, thus preventing power outages caused by insulation issues. Simultaneously, it can measure the conductor resistance of the cable to determine if there are any breaks or corrosion in the conductor. The device also has the capability to detect partial discharge in cables, locating potential fault points by capturing discharge signals.

[0003] An existing cable X-ray visualization inspection device includes an inspection table. An L-shaped connecting plate is fixedly connected to one side of the top of the inspection table. An X-ray detector is fixedly connected to the top of the L-shaped connecting plate. The X-ray detector is located above the inspection table. Symmetrical placement plates are fixedly connected to the top of the inspection table. Symmetrical fixing components are fixedly connected to both ends of the top of the inspection table. Cable winding assemblies are fixedly connected to both ends of the inspection table.

[0004] The aforementioned technologies involve placing the cable on a mounting plate during cable inspection and manually operating a fixing assembly to move and secure the cable section during inspection, preventing it from shaking due to external forces during X-ray detector testing. However, in actual factory inspection processes, where large quantities of cables need to be inspected, the manual fixing method not only increases the workload of workers but also reduces inspection efficiency and the practicality of the equipment. Utility Model Content

[0005] This invention proposes a visual cable inspection device, which reduces the labor intensity of workers and improves inspection efficiency and practicality.

[0006] The technical solution of this utility model is as follows: A visual cable inspection device includes an inspection platform. The inspection platform has fixing mechanisms for fixing cables on both sides. Each fixing mechanism includes a fixing seat, fixing rods on both sides of the fixing seat, a sliding plate slidably connected to the fixing rods, a fixing plate on the side of the sliding plate near the fixing seat, and an automatic telescopic drive assembly for driving the sliding plate to move towards the fixing seat. The fixing seat and fixing rods are fixedly connected to the inspection platform, and the automatic telescopic drive assembly is located above the fixing rods.

[0007] Furthermore, the automatic telescopic drive assembly includes a top plate fixed to the top of the fixed rod, a first connecting rod rotatably connected to both sides of the top plate, a second connecting rod rotatably connected to both sides of the sliding plate, a push plate, a third connecting rod rotatably connected to both sides of the push plate, and a cylinder. One end of each of the first connecting rods is rotatably connected to one end of each of the second connecting rods. The side of the third connecting rod away from the push plate is rotatably connected to the first and second connecting rods. The cylinder is located at the top of the top plate, and the telescopic rod of the cylinder is fixedly connected to the push plate.

[0008] Furthermore, an adjusting screw is fixedly connected to the top of the fixing rod, and adjusting nuts are threadedly connected to both the upper and lower sides of the adjusting screw. Each adjusting nut abuts against the upper and lower sides of the top plate. Adjusting holes are provided on both sides of the top plate. The inner diameter of the adjusting hole is larger than the outer diameter of the adjusting screw, and the adjusting screw is located inside the adjusting hole.

[0009] Furthermore, a sliding rod is fixedly connected to the top of the push plate, and a sliding groove is provided inside the telescopic rod of the cylinder. The sliding rod is slidably connected to the inner wall of the sliding groove. An adjustment groove is provided on one side of the sliding groove, and a locking assembly for fixing the sliding rod is provided in the adjustment groove.

[0010] Furthermore, the locking assembly includes a fixing bolt and a washer. The fixing bolt is disposed inside the adjustment groove and threadedly connected to the sliding rod. The outer diameter of the fixing bolt is smaller than the width of the adjustment groove. The bolt head of the fixing bolt abuts against the side of the telescopic rod, and the washer is disposed between the bolt head and the telescopic rod.

[0011] Furthermore, the fixing base and the fixing plate are provided with arc-shaped grooves on opposite sides, and the fixing base is provided with receiving grooves on both sides. The width of the fixing plate is smaller than the width of the receiving grooves.

[0012] Furthermore, each of the arc-shaped grooves is provided with a rubber pad, and the rubber pad is fixedly connected to the corresponding fixing seat and fixing plate respectively.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] The fixing mechanism of this invention can easily fix the cable, ensuring the stability of the cable position during testing and preventing cable swaying from affecting the accuracy of the test results. The automatic telescopic drive assembly can automatically drive the sliding plate, moving the fixing plate towards the fixing seat. Compared with manual fixing, this significantly improves cable fixing efficiency, reduces human error, enhances the consistency and reliability of the fixing process, and thus reduces the labor intensity of workers, improving testing efficiency and practicality. Furthermore, the sliding connection between the sliding plate and the fixing rod restricts the sliding plate's degrees of freedom, allowing it to move only along the axis of the fixing rod, thereby ensuring the stability and reliability of the sliding plate's movement and preventing deviation during movement.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] refer to Figure 1-6 A visual cable inspection device includes an inspection table 1. An L-shaped connecting plate 5 is fixedly connected to one side of the top of the inspection table 1. An X-ray detector 6 is fixedly connected to the top of the L-shaped connecting plate 5, positioned above the inspection table 1. The X-ray detector 6 uses the penetrating properties of X-rays to perform visual inspection of the cable. When X-rays irradiate the cable, different cable parts (such as metal conductors, insulation layers, and sheaths) absorb X-rays to varying degrees. As X-rays pass through the cable, the metal conductor absorbs more X-rays, resulting in less transmission in that area, while lighter materials such as the insulation layer allow more X-rays to pass through. The X-rays passing through the cable are received by a sensing element mounted on the detector and converted into signals. These signals are then processed and converted into images, thereby visualizing the internal structure of the cable. This allows operators to clearly observe defects, damage, or other abnormalities within the cable, ensuring the quality and safety of the cable.

[0025] Both sides of the testing table 1 are provided with fixing mechanisms for fixing cables. The fixing mechanism includes a fixing base 101, fixing rods 102 provided on both sides of the fixing base 101, a sliding plate 103 slidably connected to the fixing rods 102, a fixing plate 104 provided on the side of the sliding plate 103 near the fixing base 101, and an automatic telescopic drive assembly for driving the sliding plate 103 to move towards the fixing base 101. The fixing base 101 and the fixing rods 102 are fixedly connected to the testing table 1, and the automatic telescopic drive assembly is located above the fixing rods 102.

[0026] The automatic telescopic drive assembly automatically drives the sliding plate 103, causing the fixed plate 104 to move towards the fixed seat 101. Compared to manual fixing, this significantly improves cable fixing efficiency, reduces human error, enhances the consistency and reliability of the fixing process, and consequently reduces the labor intensity of workers, improving testing efficiency and practicality. Furthermore, the sliding connection between the sliding plate 103 and the fixed rod 102 restricts the degree of freedom of the sliding plate 103, allowing it to move only along the axis of the fixed rod 102. This ensures the stability and reliability of the sliding plate 103's movement and prevents deviation during movement.

[0027] Specifically, the automatic telescopic drive assembly includes a top plate 2 fixed to the top of the fixed rod 102, a first connecting rod 201 rotatably connected to both sides of the top plate 2, a second connecting rod 202 rotatably connected to both sides of the sliding plate 103, a push plate 203, a third connecting rod 205 rotatably connected to both sides of the push plate 203, and a cylinder 204. One end of each first connecting rod 201 is rotatably connected to one end of each second connecting rod 202. The side of the third connecting rod 205 away from the push plate 203 is rotatably connected to the first connecting rod 201 and the second connecting rod 202. The cylinder 204 is located on the top of the top plate 2, and the telescopic rod 2041 of the cylinder 204 is fixedly connected to the push plate 203. The cylinder 204 is fixed on the top plate 2.

[0028] During testing, the inspector places the cable between the fixed base 101 and the fixed plate 104, then activates the cylinder 204, causing the telescopic rod 2041 of the cylinder 204 to move the push plate 203 downward. The push plate 203 further moves the third connecting rod 205 downward. Simultaneously, the third connecting rod 205, through its connection to the first connecting rod 201 and the second connecting rod 202, moves one side of the second connecting rod 202 downward. The specific principle is as follows: When the third connecting rod 205 moves downward, since the rotation points of the first connecting rod 201, the second connecting rod 202, the top plate 2, and the sliding plate 103 are fixed, they cannot move horizontally but can only rotate. Therefore, the downward movement of the third connecting rod 205 causes the first connecting rod 201 and the second connecting rod 202 to change from an inclined state to a vertical state. Since the top is fixed to the fixed rod 102, the third connecting rod 205, through the second connecting rod 202, moves the sliding plate 103 downward, thereby clamping and fixing the cable between the fixed plate 104 and the fixed base 101.

[0029] It should be noted that in this embodiment, the sliding plate 103 is not directly connected to the telescopic rod 2041 of the cylinder 204. Instead, the fixed plate 104 is driven to move indirectly. This design takes into account the motion characteristics of the cylinder 204. When the cylinder 204 starts, it may generate a large impact force, which may cause the fixed plate 104 to exert excessive clamping force on the cable, thereby causing cable damage. The multi-stage transmission structure, through the connection of the first link 201, the second link 202, and the third link 205, provides a buffering effect to a certain extent, effectively reducing the impact force generated by the cylinder 204, reducing the risk of cable damage due to excessive impact force, and improving practicality.

[0030] Furthermore, an adjusting screw 3 is fixedly connected to the top of the fixed rod 102, and adjusting nuts 301 are threadedly connected to both the upper and lower sides of the adjusting screw 3. Each adjusting nut 301 abuts against the upper and lower sides of the top plate 2. Adjusting holes 302 are provided on both sides of the top plate 2. The inner diameter of the adjusting hole 302 is larger than the outer diameter of the adjusting screw 3, and the adjusting screw 3 is located inside the adjusting hole 302.

[0031] The height of the top plate 2 can be easily adjusted by adjusting the screw 3 and the adjusting nut 301. When it is necessary to inspect cables of different diameters or thicknesses, the top plate 2 can be raised or lowered to a suitable height by rotating the adjusting nut 301, thereby adjusting the height of the entire automatic telescopic mechanism. This ensures that the fixing mechanism can better adapt to the fixing of cables of different specifications, further improving the versatility and adaptability of the device.

[0032] When it is necessary to lower the height of the top plate 2, the adjusting nut 301 at the bottom of the top plate 2 can be rotated to lower it to a suitable height. Then, the top plate 2 can be moved downwards (since the inner diameter of the adjusting hole 302 is larger than the outer diameter of the adjusting screw 3, the top plate 2 can move freely on the adjusting screw 3). Continue this movement until one side of the top plate 2 contacts the lower adjusting nut 301. At this point, the upper adjusting nut 301 is then screwed downwards until it contacts the top of the top plate 2, thus fixing the position of the top plate 2 and completing the height adjustment.

[0033] In this embodiment, a sliding rod 4 is fixedly connected to the top of the push plate 203. A sliding groove 401 is provided inside the telescopic rod 2041 of the cylinder 204. The sliding rod 4 is slidably connected to the inner wall of the sliding groove 401. An adjustment groove 402 is provided on one side of the sliding groove 401, and a locking assembly for fixing the sliding rod 4 is provided within the adjustment groove 402. The sliding rod 4 is slidably connected to the sliding groove 401 within the telescopic rod 2041 of the cylinder 204, and the extension length of the sliding rod 4 can be adjusted and fixed through the adjustment groove 402 and the locking assembly. This means that the travel of the push plate 203 can be flexibly adjusted according to the fixing requirements of different cables, thereby more precisely controlling the fixing force of the sliding plate 103 on the cable and improving the controllability of the fixing effect.

[0034] Furthermore, this method eliminates the need for inspectors to repeatedly adjust the stroke of cylinder 204 when inspecting cables of different diameters. With the telescopic rod 2041 of cylinder 204 extended, the sliding rod 4 is released via the locking assembly, allowing it to move downwards within the slide groove 401 until the push plate 203, through the third connecting rod 205, drives the fixing plate 104 to contact and fix with the cable. At this point, the locking assembly secures the sliding rod 4 within the slide groove 401, and then the telescopic rod 2041 is retracted, completing the adjustment process. This eliminates the need for repeated adjustments to cylinder 204, further reducing labor intensity and improving inspection efficiency.

[0035] Specifically, the locking assembly includes a fixing bolt 403 and a washer 404. The fixing bolt 403 is located inside the adjusting groove 402 and is threadedly connected to the sliding rod 4. The outer diameter of the fixing bolt 403 is smaller than the width of the adjusting groove 402. The bolt head of the fixing bolt 403 abuts against the side of the telescopic rod 2041, and the washer 404 is located between the bolt head and the telescopic rod 2041.

[0036] The locking assembly, consisting of a fixing bolt 403 and a washer 404, has a simple structure and is easy to operate. By screwing the fixing bolt 403 into the adjusting groove 402 and threading it with the sliding rod 4, the sliding rod 4 can be firmly fixed in the desired position using the principle of friction. At the same time, the washer 404 increases the contact area between the bolt head and the side of the telescopic rod 2041, preventing the bolt head from damaging the surface of the telescopic rod 2041 and enhancing the stability of the fixation, thus preventing the bolt from loosening.

[0037] Secondly, by utilizing the principle of friction, the sliding rod 4 can be fixed at any position inside the adjusting groove 402, further improving the applicability and usability of the device.

[0038] In this embodiment, an arc-shaped groove 1011 is provided on one side of the fixing base 101 and the fixing plate 104 respectively, and a receiving groove 1012 is provided on both sides of the fixing base 101. The width of the fixing plate 104 is smaller than the width of the receiving groove 1012, and the position of the fixing plate 104 corresponds to the position of the receiving groove 1012. The arc-shaped groove 1011 can better fit the shape of the cable, increase the contact area with the cable, thereby improving the fixation firmness and reducing the possibility of cable displacement during the testing process. The receiving groove 1012 provides sufficient space for the fixing plate 104 to move towards the fixing base 101. Furthermore, a rubber pad is provided inside each arc-shaped groove 1011, and the rubber pad is fixedly connected to the corresponding fixing base 101 and fixing plate 104 respectively. The rubber pad has good flexibility and elasticity. It is set inside the arc groove 1011 and can play a buffering role when fixing the cable. It prevents the fixing seat 101 and fixing plate 104 from making direct hard contact with the cable surface, thereby effectively protecting the insulation layer of the cable surface from being scratched or damaged, and ensuring the integrity and safety of the cable during the testing process.

[0039] Working principle:

[0040] During testing, the inspector places the cable between the fixed base 101 and the fixed plate 104, then activates the cylinder 204, causing the telescopic rod 2041 of the cylinder 204 to move the push plate 203 downward. The push plate 203 further moves the third connecting rod 205 downward. Simultaneously, the third connecting rod 205, through its connection to the first connecting rod 201 and the second connecting rod 202, moves one side of the second connecting rod 202 downward. The specific principle is as follows: When the third connecting rod 205 moves downward, since the rotation points of the first connecting rod 201, the second connecting rod 202, the top plate 2, and the sliding plate 103 are fixed, they cannot move horizontally but can only rotate. Therefore, the downward movement of the third connecting rod 205 causes the first connecting rod 201 and the second connecting rod 202 to change from an inclined state to a vertical state. Since the top is fixed to the fixed rod 102, the third connecting rod 205, through the second connecting rod 202, moves the sliding plate 103 downward, thereby clamping and fixing the cable between the fixed plate 104 and the fixed base 101.

[0041] After the test is completed, simply retract the telescopic rod 2041 of cylinder 204.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
