Description

Technical Field

[0001] This invention relates to the field of cable head insulation aging detection, specifically to a cable head insulation aging detection device. Background Technology

[0002] With the rapid development of power transmission and new energy industries, cables, as the core carrier of power transmission, are crucial to the safety of the power grid and the stability of power supply. Cable heads are key components for achieving sealing and insulation at cable terminals and joints, and their insulation performance and aging resistance determine the service life and operational safety of the cable system.

[0003] The current cable head insulation aging test process is as follows: the operator places the cable head workpieces to be tested one by one on the placement seat of the test station, manually adjusts the position of the workpiece so that the end is roughly aligned with the side drive cylinder, starts the top pressing mechanism to clamp the workpiece, then starts the cylinder to push the clamping structure to clamp the end of the workpiece. After confirming that the clamping is in place, the test system is started. The workpiece aging is accelerated by discharge and high temperature environment to complete the test. After the test is completed, each clamping mechanism is released in turn, and then the operator removes the workpieces one by one. After the unloading is completed, the next batch of workpieces is loaded.

[0004] However, in existing aging testing devices, the workpiece is difficult to be coaxial with the lateral drive cylinder after placement. Operators need to carefully observe and adjust the position of the workpiece. Alignment deviation can easily cause the workpiece to be bumped and the sealing surface to be damaged during cylinder insertion, affecting the accuracy of the test results. At the same time, after the test is completed, the workpieces need to be removed manually one by one, which is cumbersome. Batch testing is labor-intensive and has a long operation cycle, which restricts the overall testing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a cable head insulation aging detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable head insulation aging detection device, comprising a device body and two sets of drive mechanisms, each set of drive mechanisms having a fixing mechanism at its top, the device body having a pressing mechanism at its top, the drive mechanisms having an auxiliary mechanism at their top, and the drive mechanisms having a limiting mechanism at their top. The drive mechanism includes a mounting base, a fixed side plate, a placement plate, and a first cylinder. The mounting base is fixedly installed on the top of the equipment body. A fixed side plate is fixedly installed on one side of the top of the mounting base, and a placement plate is fixedly installed on the other side of the top of the mounting base. Multiple sets of first cylinders are fixedly installed on one side of the fixed side plate. The fixing mechanism includes multiple sets of placement seats and multiple sets of limiting components. Multiple sets of placement seats are fixedly installed on one side of the top of the placement plate. The top of each set of placement seats is slidably connected to the limiting component, and the cooperation between the placement seat and the limiting component plays the role of limiting the end of the workpiece. The auxiliary mechanism includes a driving component and two sets of movable rods. The driving component is fixedly installed outside the telescopic ends of multiple sets of first cylinders. The movable rods are slidably connected to the driving component and are used to push multiple sets of limiting components. The limiting mechanism includes a connecting plate, which is fixedly installed between the ends of two sets of limiting members, and a locking block is fixedly connected to one side of the connecting plate.

[0007] Preferably, the fixing mechanism further includes a movable plate, two sets of connecting rods and two sets of sliding rods. The movable plate is fixedly connected to one side of the multiple sets of limiting members, and the two sets of connecting rods are fixedly connected to the bottom of the movable plate. The connecting rods are slidably sleeved on the outer wall of the sliding rods.

[0008] Preferably, each set of slide rods is fitted with a return spring, and the connecting rod and the placement plate are elastically connected by the return spring.

[0009] Preferably, the pressing mechanism includes a lifting plate and two sets of second cylinders, the second cylinders are fixedly installed on the top of the equipment body, and the bottom extension ends of the two sets of second cylinders are fixedly connected to the lifting plate.

[0010] Preferably, the auxiliary mechanism further includes an adjustment seat, and two sets of the adjustment seats are fixedly installed on the side of the drive member near the fixed mechanism, and the adjustment seat is elastically connected with an elastic locking block inside; The movable rod is slidably connected inside the adjusting seat, and a guide groove is provided on the outer wall of the movable rod.

[0011] Preferably, the limiting mechanism further includes a limiting seat and a limiting pin. The limiting seat is fixedly installed on the top side of the placement plate, and the limiting seat has a movable groove inside. The limiting pin is slidably installed on the inner side of the lifting plate.

[0012] Preferably, the end of the locking block is protruding and one side of the end is inclined, and the bottom of the limiting pin cooperates with the inclined surface of the end of the locking block.

[0013] Preferably, each set of placement seats is fixedly installed with slide rails on both sides of the top, and each set of placement seats is slidably connected to the limiting member through the slide rails.

[0014] Preferably, each set of slide rods is externally fixedly equipped with an adjusting member, which is located on the side of the connecting rod near the fixed side plate and is used to limit the reset stroke of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a placement seat to support the end of the workpiece, while a sliding limiting member forms a lateral constraint. Then, a top pressing mechanism provides axial clamping. This allows the workpiece to be fixed from multiple degrees of freedom simultaneously, effectively preventing the workpiece from shifting, rotating, or moving during the inspection process. When the limiting member is clamped in place, the workpiece is restricted between the limiting member and the placement seat. The end of the workpiece is coaxial with the extension end of the drive cylinder. After the drive cylinder is started, it can naturally insert into the workpiece. This allows the lateral cylinder to complete the insertion process without careful manual observation during the workpiece fixing process, avoiding the problem that the workpiece is not on the same axis as the extension end of the cylinder in the initial state, which can easily cause the workpiece to rotate during the fixing process.

[0016] 2. During the movement of the limiting component towards the clamping position, the end connecting plate drives the locking block to simultaneously enter the limiting seat. Through the inclined plane transmission, the internal limiting pin is automatically lifted. When the clamping is in place, after the locking block passes the limiting pin, the limiting pin naturally falls to form a reverse locking, realizing mechanical self-locking in the clamping state. This purely mechanically triggered self-locking structure requires no additional electronic control components or sensing devices. It can adapt to the discharge and high-temperature conditions during the aging test process, and is not affected by electromagnetic interference and temperature fluctuations. It ensures that the workpiece remains in a fixed position throughout the entire aging test cycle. At the same time, after the test is completed, when the lifting plate is raised, since the workpiece is restricted between the limiting component and the placement seat, the workpiece can naturally fall off the fixed component on the lifting plate. There is no need for subsequent manual removal of the workpieces from the fixed component one by one, thereby saving manual operation, optimizing the entire test process, and indirectly improving the test efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 The present invention provides the following technical solution: a cable head insulation aging detection device, comprising a device body 1 and two sets of drive mechanisms 2, each set of drive mechanisms 2 having a fixing mechanism 3 on its top, the device body 1 having a pressing mechanism 4 on its top, the drive mechanism 2 having an auxiliary mechanism 5 on its top, and the drive mechanism 2 having a limiting mechanism 6 on its top. The user connects the T-shaped workpiece to the testing unit, applies insulating material to the inside of the workpiece, and then places the workpiece on the mounting platform on top of the equipment body 1. One end of the T-shaped workpiece is placed in the fixing mechanism 3. Then, the pressing mechanism 4 is activated first, followed by the driving mechanism 2, which fixes the workpiece with the fixing mechanism 3.

[0021] As one embodiment of the present invention, the drive mechanism 2 includes a mounting base 20, a fixed side plate 21, a placement plate 22 and a first cylinder 23. The mounting base 20 is fixedly installed on the top of the equipment body 1. The fixed side plate 21 is fixedly installed on one side of the top of the mounting base 20, and the placement plate 22 is fixedly installed on the other side of the top of the mounting base 20. Multiple sets of first cylinders 23 are fixedly installed on one side of the fixed side plate 21. When the drive mechanism 2 is started, the first cylinder 23 is mounted on the fixed side plate 21, and the fixed side plate 21 is mounted on the top of one side of the mounting base 20. When the first cylinder 23 is started, the workpiece can be fixed.

[0022] In one embodiment of the present invention, the fixing mechanism 3 includes multiple sets of placement seats 30 and multiple sets of limiting members 32. Multiple sets of placement seats 30 are fixedly installed on one side of the top of the placement plate 22. The top of each set of placement seats 30 is slidably connected to the limiting member 32, and the cooperation between the placement seat 30 and the limiting member 32 serves to limit the end of the workpiece. Slide rails 300 are fixedly installed on both sides of the top of each set of placement seats 30, and each set of placement seats 30 is slidably connected to the limiting member 32 through the slide rails 300. The limiting member 32 slides on the top of the placement seat 30 by sliding with the slide rail 300. A conical surface is provided on one side of the limiting member 32. Therefore, the movement of the limiting member 32 can restrict the end of the workpiece placed inside the placement seat 30, so that the workpiece is restricted between the placement seat 30 and the limiting member 32. Furthermore, the fixing mechanism 3 also includes a movable plate 31, two sets of connecting rods 33 and two sets of sliding rods 34. The movable plate 31 is fixedly connected to one side of multiple sets of limiting members 32. Two sets of connecting rods 33 are fixedly connected to the bottom of the movable plate 31. The connecting rods 33 are slidably sleeved on the outer wall of the sliding rods 34. Each set of sliding rods 34 is sleeved with a return spring 340. The connecting rods 33 and the placement plate 22 are elastically connected through the return spring 340. In the example, each set of slide rods 34 is externally fixedly equipped with an adjusting member 35. The adjusting member 35 is located on the side of the connecting rod 33 near the fixed side plate 21 and is used to limit the reset stroke of the connecting rod 33. Under the elastic action of the reset spring 340, the moving plate 31 will be carried by the connecting rod 33 until the bottom of the connecting rod 33 is in contact with the adjusting member 35.

[0023] In one embodiment of the present invention, the pressing mechanism 4 includes a lifting plate 40 and two sets of second cylinders 41. The second cylinders 41 are fixedly installed on the top of the equipment body 1, and the bottom extension ends of the two sets of second cylinders 41 are fixedly connected to the lifting plate 40. After the second cylinders 41 are started, they will lower the lifting plate 40. The bottom of the lifting plate 40 is equipped with a fixing component corresponding to each workpiece. After the lifting plate 40 is lowered, the fixing component will be inserted into the workpiece. With the cooperation of the mounting platform on the top of the equipment body 1, the position of the workpiece can be fixed.

[0024] As one embodiment of the present invention, the auxiliary mechanism 5 includes a driving member 50 and two sets of movable rods 52. The driving member 50 is fixedly installed outside the telescopic ends of multiple sets of first cylinders 23. The movable rods 52 are slidably connected to the driving member 50. The movable rods 52 are used to push multiple sets of limiting members 32. The auxiliary mechanism 5 also includes an adjusting seat 51. The two sets of adjusting seats 51 are fixedly installed on the side of the driving member 50 near the fixing mechanism 3. An elastic locking block 510 is elastically connected inside the adjusting seat 51. The movable rods 52 are slidably connected inside the adjusting seat 51. A guide groove 520 is opened on the outer wall of the movable rods 52. The drive component 50 is installed on the outer wall of the telescopic end of the multiple sets of first cylinders 23. When the drive component 50 moves with the telescopic end of the first cylinder 23, the movable rod 52 installed on the side of the drive component 50 close to the fixed mechanism 3 will abut against the side wall of the connecting rod 33, and drive the moving plate 31 to move through the connecting rod 33.

[0025] As one embodiment of the present invention, the limiting mechanism 6 includes a connecting plate 61, which is fixedly installed between the ends of two sets of limiting members 32. A locking block 610 is fixedly connected to one side of the connecting plate 61. The limiting mechanism 6 also includes a limiting seat 60 and a limiting pin 62. The limiting seat 60 is fixedly installed on the top side of the placement plate 22. The limiting seat 60 has an open movable groove 600 inside. The limiting pin 62 is slidably installed inside the lifting plate 40. The end of the locking block 610 is protruding and one side of the end is inclined. The bottom of the limiting pin 62 cooperates with the inclined end of the locking block 610. When the lifting plate 40 descends, the limiting pin 62 will first enter the limiting seat 60 at the top of the placement plate 22. When the locking block 610 moves with the limiting member 32, its end will first enter the horizontally opened groove of the movable groove 600. Since the limiting pin 62 has been inserted into the movable groove 600 at this time, but the side of the bottom end of the limiting pin 62 close to the connecting plate 61 is also set as an inclined surface, after the connecting plate 61 enters the movable groove 600 with the limiting member 32, under the action of the inclined surface transmission, the connecting plate 61 will first lift the limiting pin 62. After the protruding end of the connecting plate 61 passes the limiting pin 62, the limiting pin 62 will fall naturally under the action of gravity, locking the connecting plate 61 inside the movable groove 600.

[0026] Working principle: When in use, after connecting the power supply, the user first connects the T-shaped workpiece to be tested to the testing unit and applies insulating material to the inside of the workpiece. Then, the workpiece is placed on the mounting platform on the top of the equipment body 1. One end of the T-shaped workpiece to be tested is placed in the fixing mechanism 3. Then, the pressing mechanism 4 starts first, and then the driving mechanism 2 starts, which fixes the workpiece with the fixing mechanism 3. After the workpiece is placed on top of the equipment body 1, the second cylinder 41 is started and will bring the lifting plate 40 down. The bottom of the lifting plate 40 is equipped with a fixing component corresponding to each group of workpieces. After the lifting plate 40 is lowered, the fixing component will be inserted into the workpiece. With the cooperation of the mounting platform on the top of the equipment body 1, the position of the workpiece can be fixed. When the lifting plate 40 descends, the limiting pin 62 will first enter the limiting seat 60 at the top of the placement plate 22. After the limiting pin 62 enters the movable groove 600 inside the limiting seat 60, the limiting pin 62 will stop descending after contacting the bottom of the movable groove 600. The lifting plate 40 will continue to descend until the workpiece position is fixed. When the drive mechanism 2 is started, the first cylinder 23 is installed on the fixed side plate 21, and the fixed side plate 21 is installed on the top of one side of the mounting base 20. When the first cylinder 23 is started, its telescopic end will extend into the area between the limiting member 32 and the placement base 30. During the movement of the telescopic end of the first cylinder 23, it will move the auxiliary mechanism 5 synchronously, thereby driving the fixed mechanism 3 to work. The drive component 50 is installed on the outer wall of the telescopic end of the multiple sets of first cylinders 23. When the drive component 50 moves with the telescopic end of the first cylinder 23, the movable rod 52 installed on the side of the drive component 50 near the fixed mechanism 3 will abut against the side wall of the connecting rod 33. The moving plate 31 is driven to move through the connecting rod 33. At the bottom of the connecting rod 33, it is sleeved on the outside of the slide rod 34. When the connecting rod 33 is driven by the movable rod 52, it will squeeze the return spring 340. The top of both sides of the placement base 30 is provided with slide rails 300 that cooperate with the limiting member 32. Therefore, when the moving plate 31 moves passively, the limiting member 32 slides on the top of the placement base 30 by sliding with the slide rails 300. A conical surface is provided on one side of the limiting member 32, so that the movement of the limiting member 32 can restrict the end of the workpiece placed inside the placement seat 30, so that the workpiece is restricted between the placement seat 30 and the limiting member 32. When the limiting member 32 is passively moved to the side wall of the placement plate 22 and fits against it, the limiting member 32 will be difficult to move further. At this time, the first cylinder 23 continues to move with the auxiliary mechanism 5. The movable rod 52 will press against the elastic block 510 installed inside the adjusting seat 51 in the opposite direction. Under the guidance of the guide groove 520, the movable rod 52 slides in the adjusting seat 51, so as not to affect the operation of the first cylinder 23. As the limiting member 32 approaches the placement plate 22, the limiting mechanism 6 will restrict the fixing mechanism 3. The connecting plate 61 installed between the two sets of limiting members 32 will move together with the limiting member 32. A locking block 610 is installed on the side of the connecting plate 61 that is close to the placement plate 22. The end of the locking block 610 is protruding and one side is inclined. When the locking block 610 moves with the limiting member 32, its end will first enter the horizontally opened groove of the movable groove 600. Since the limiting pin 62 has been inserted into the movable groove 600 at this time, the bottom end of the limiting pin 62 near the connecting plate 61 is also set as an inclined surface. Therefore, after the connecting plate 61 enters the movable groove 600 with the limiting member 32, under the action of the inclined surface transmission, the connecting plate 61 will first lift the limiting pin 62, so that the limiting pin 62 slides in the lifting plate 40. After the protruding end of the connecting plate 61 passes the limiting pin 62, the limiting pin 62 will fall naturally under the action of gravity, and the connecting plate 61 will be stuck inside the movable groove 600. After the extension end of the first cylinder 23 moves further, since one end of the workpiece has been restricted between the placement seat 30 and the limiting member 32, the extension end of the first cylinder 23 can smoothly insert into the interior of the workpiece. After the workpiece is fixed, the equipment body 1 will discharge the workpiece through the detection unit to accelerate its aging time in order to complete the aging detection of the workpiece. After the test is completed, the first cylinders 23 on both sides of the equipment body 1 will start first, taking the auxiliary mechanism 5 back to the initial position. When the drive component 50 moves back with the first cylinder 23, the end of the movable rod 52 away from the fixed mechanism 3 will first contact the side wall of the fixed side plate 21. Then, as the first cylinder 23 continues to work, the movable rod 52 will slide inside the adjusting seat 51 until the elastic block 510 is engaged in the slot of the movable rod 52. Inside the movable slot 600, the limiting pin 62 restricts the connecting plate 61, so the entire fixing mechanism 3 cannot be reset. At this time, the pressing mechanism 4 will be activated, and the second cylinder 41 will lift the lifting plate 40. Since the workpiece is restricted between the placement seat 30 and the limiting member 32, it cannot rise with the multiple sets of fixing components on the lifting plate 40. Therefore, the workpiece will automatically detach from the fixing components as the lifting plate 40 rises. When the lifting plate 40 rises, the limiting pin 62 does not initially move with the lifting plate 40. It is only when the lifting plate 40 contacts the top protrusion of the limiting pin 62 that the limiting pin 62 will rise with the lifting plate 40. After the limit pin 62 rises, it will disengage from the movable groove 600, thereby releasing the restriction on the connecting plate 61. At this time, under the elastic action of the return spring 340, the moving plate 31, the connecting plate 61 and the locking block 610 will be synchronously reset through the connecting rod 33 until the bottom of the connecting rod 33 is in contact with the adjusting part 35. The fixing mechanism 3 and the limit mechanism 6 will then return to their initial positions so that the next set of workpieces can be inspected. It should be emphasized that the cylinder working principle, aging detection principle, slide rail 300 transmission principle and inclined plane transmission principle involved in this invention are all existing known technologies. At the same time, the specific models of the first cylinder 23 and the second cylinder 41, the elastic coefficients of the elastic block 510 and the return spring 340, and the specific sizes of the limiting member 32 and the placement seat 30 need to be flexibly adjusted according to actual use, and will not be discussed in detail.
