Description

An electrode sampling device Technical Field

[0001] This utility model belongs to the field of sampling device technology, and specifically relates to an electrode sampling device. Background Technology

[0002] Carbon electrodes are conductive electrodes made from carbonaceous materials such as anthracite and metallurgical coke (or petroleum coke) as raw materials, coal tar pitch as a binder, without graphitization, and formed by pressing and firing. Currently, carbon electrodes mainly include multi-ash electrodes (electrodes produced from anthracite, metallurgical coke, and pitch coke), regenerated electrodes (electrodes produced from artificial graphite and natural graphite), carbon resistance rods (i.e., carbon checker bricks), carbon anodes (prebaked anodes produced from petroleum coke), and calcined electrode blanks, etc.

[0003] When inspecting carbon electrodes, it is necessary to first sample the carbon electrodes. In the routine sampling process, workers usually use a sampling device to drill a hole in the head of the carbon electrode to take the sample. The sampling device generally consists of a motor and a sampling drill bit, which is relatively bulky. Workers need to carry it around, which is inconvenient and physically demanding. Moreover, the drilling process also generates a lot of dust, which is dispersed into the air and forms dust, affecting the surrounding environment and the health of workers.

[0004] Therefore, the applicant is considering improving the existing sampling device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned defects in the existing technology, the present invention provides an electrode sampling device, including a vehicle body, a dustproof mechanism, a drilling mechanism and an adjustment mechanism. The vehicle body includes a base plate and a fixed bracket. The base plate is provided with moving wheels. The fixed bracket is provided on the top of the base plate. The fixed bracket adopts a frame structure formed by multiple vertical bars and horizontal bars.

[0006] The dustproof mechanism is located on the front side of the fixed bracket. The dustproof mechanism includes a front fixed ring and a rear fixed ring, and a dustproof cover is provided between the front fixed ring and the rear fixed ring. The rear fixed ring is fixed to the front end of the fixed bracket.

[0007] The drilling mechanism is used to drill holes in the head of the carbon electrode for sampling.

[0008] The adjustment mechanism is used to drive the drilling mechanism to move back and forth.

[0009] Optionally, the casters are universal casters with locking function, and a push rod is provided on the rear side of the fixed bracket.

[0010] Specifically, the casters facilitate movement, and the push rod makes it easy to push the vehicle.

[0011] Optionally, an annular conical surface is provided on the inner side of the front fixing ring.

[0012] Specifically, since the head of the carbon electrode is a convex conical surface, the annular conical surface in the front fixing ring can perfectly match the shape of the carbon electrode head, which can increase the contact area between the two and improve the sealing performance.

[0013] Optionally, the adjustment mechanism includes two limiting blocks, a horizontal slide rail, a slide block, and a threaded rod. The two limiting blocks and the horizontal slide rail are fixed on the top surface of the base plate. The two limiting blocks include a front limiting block and a rear limiting block arranged front to back. The horizontal slide rail and the slide block are located between the two limiting blocks, and the bottom of the slide block is slidably connected to the horizontal slide rail. The threaded rod is arranged laterally, and the middle part of the threaded rod passes through the rear limiting block. The threaded rod and the rear limiting block are rotatably connected. The front end of the threaded rod passes through the slide block and is rotatably connected to the front limiting block. The slide block is slidably connected to the threaded rod through the nut pair of the threaded rod.

[0014] Optionally, the height of both limit blocks is less than the height of the slide block.

[0015] Optionally, an adjustment handle is installed at the rear end of the threaded rod.

[0016] Optionally, the drilling mechanism includes a base, a drive motor, and a drill rod. The base is fixedly connected above the slide, the drive motor is mounted above the base, the drill rod is located in front of the drive motor, the rear end of the drill rod is connected to the output shaft of the drive motor through a coupling, and a support seat is provided at the bottom of the coupling. A sampling drill bit is installed at the front end of the drill rod, and the height of the sampling drill bit is adapted to the position where the carbon electrode head center needs to be drilled for sampling.

[0017] This invention also includes other components that enable the electrode sampling device to function properly, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art, such as drive motors.

[0018] The working principle of this invention is as follows: During sampling, a worker pushes the vehicle to a position near the carbon electrode, determines the sampling location, and secures the vehicle. Another worker then unfolds the dust cover and places the front retaining ring over the head of the carbon electrode. The front retaining ring can be held in place by hand or tied to the head of the carbon electrode with a rope. The annular conical surface of the front retaining ring matches the shape of the carbon electrode head to increase the contact area and improve sealing. Then, another worker starts the drive motor, causing the drill rod to rotate and proceed... The sampling drill bit is rotated, and the adjusting handle is manually rotated to drive the threaded rod to rotate, causing the slide to move forward along the horizontal slide rail. This, in turn, moves the entire drilling mechanism forward. The drill rod passes through the rear fixing ring, dust cover, and front fixing ring until the sampling drill bit drills into the head of the carbon electrode for sampling. The dust generated during the drilling process is blocked by the dust cover to reduce its escape. After sampling is completed, the drive motor is turned off, and the adjusting handle is rotated in the opposite direction to move the drilling mechanism backward. The front fixing ring is then removed, the dust cover is retracted, and the sample is removed.

[0019] The beneficial effects of this utility model are that the device has a simple structure and is easy to use, and is suitable for sampling operations on the head of carbon electrodes; the vehicle body design facilitates the movement of the entire device, saving workers' physical strength; the dustproof mechanism design can collect most of the dust in the dustproof cover, which not only achieves the dustproof effect, reduces environmental pollution, protects the environment, and creates a clean and comfortable working environment for workers, but also makes it easy to centrally process the dust collected in the dustproof cover. Most of this dust comes from the debris on the carbon electrode, which can be recycled and reused or used as other auxiliary materials, saving materials. Attached Figure Description

[0025] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it.

[0026] Example

[0027] As shown in Figures 1-3, this utility model embodiment provides an electrode sampling device, including a vehicle body 1, a dustproof mechanism 2, an adjustment mechanism 3, and a drilling mechanism 4. The vehicle body 1 includes a base plate 5 and a fixed bracket 6. A universal wheel 7 with a locking function is provided below the base plate 5, which facilitates movement. The fixed bracket 6 is located above the base plate 5. The fixed bracket 6 adopts a frame structure formed by multiple vertical and horizontal bars. A push rod 8 is provided on the rear side of the fixed bracket 6, which facilitates pushing the vehicle body 1.

[0028] The dustproof mechanism 2 is located on the front side of the fixed bracket 6. The dustproof mechanism 2 includes a front fixed ring 9 and a rear fixed ring 10 arranged at the front and rear, and a dust cover 11 is provided between the front fixed ring 9 and the rear fixed ring 10. The rear fixed ring 10 is fixed to the front end of the fixed bracket 6. The inner side of the front fixed ring 9 is provided with an annular conical surface 12. Since the head of the carbon electrode 25 is a convex conical surface, the annular conical surface 12 in the front fixed ring 9 can just match the shape of the head of the carbon electrode 25, which can improve the contact surface between the two and improve the sealing performance.

[0029] The adjustment mechanism 3 includes two limiting blocks, a horizontal slide rail 13, a slide block 14, and a threaded rod 15. The two limiting blocks and the horizontal slide rail 13 are fixed on the top surface of the base plate 5. The two limiting blocks include a front limiting block 16 and a rear limiting block 17 arranged front to back. The horizontal slide rail 13 and the slide block 14 are located between the two limiting blocks, and the bottom of the slide block 14 is slidably connected to the horizontal slide rail 13. The height of the two limiting blocks is less than the height of the slide block 14. The threaded rod 15 is arranged horizontally, and the middle part of the threaded rod 15 passes through the rear limiting block 17. The threaded rod 15 and the rear limiting block 17 are rotatably connected. The front end of the threaded rod 15 passes through the slide block 14 and is rotatably connected to the front limiting block 16. The slide block 14 is slidably connected to the threaded rod 15 through the nut pair of the threaded rod 15. An adjustment handle 18 is installed at the rear end of the threaded rod 15.

[0030] The drilling mechanism 4 includes a base 19, a drive motor 20, and a drill rod 21. The base 19 is fixedly connected above the slide 14. The drive motor 20 is mounted above the base 19. The drill rod 21 is located in front of the drive motor 20. The rear end of the drill rod 21 is connected to the output shaft of the drive motor 20 through a coupling 22. A support seat 23 is provided at the bottom of the coupling 22. A sampling drill bit 24 is installed at the front end of the drill rod 21. The height of the sampling drill bit 24 is adapted to the position where the carbon electrode 25 head center needs to be drilled for sampling. In addition, the base 19 will not interfere with the rear fixing ring 10 during the back-and-forth movement.

[0031] The working principle of this utility model is as follows: During sampling, a worker pushes the vehicle body 1 to a position near the carbon electrode 25, determines the sampling position, and fixes the vehicle body 1. Then, another worker unfolds the dust cover 11 and places the front fixing ring 9 over the head of the carbon electrode 25. The front fixing ring 9 can be held down by hand or tied to the head of the carbon electrode 25 with a rope. The annular conical surface 12 in the front fixing ring 9 matches the shape of the head of the carbon electrode 25 to increase the contact area and improve the sealing. Then, another worker starts the drive motor 20, which drives the drill rod 21 to rotate, thereby driving the sampling. The drill bit 24 rotates, and the adjusting handle 18 is manually rotated to drive the threaded rod 15 to rotate, causing the slide block 14 to move forward along the horizontal slide rail 13, thereby driving the entire drilling mechanism 4 to move forward. The drill rod 21 passes through the rear fixing ring 10, the dust cover 11, and the front fixing ring 9 until the sampling drill bit 24 drills into the head of the carbon electrode 25 to drill and take a sample. The dust generated during the drilling process will be blocked inside the dust cover 11 to reduce the escape. After the sampling is completed, the drive motor 20 is turned off, and the adjusting handle 18 is rotated in the opposite direction to move the drilling mechanism 4 backward. The front fixing ring 9 is removed, the dust cover 11 is retracted, and the sample is removed.

[0032] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
