Description

Technical Field

[0001] This utility model relates to the field of carbon block processing technology, and in particular to a hole-opening device for graphite carbon bricks. Background Technology

[0002] In carbon block production, drilling is required. Manual water drilling is commonly used, where the operator stands on the workpiece, holds the drill handle with both hands, and selects a hollow drill of the same diameter as the hole size. This method is feasible for holes less than 120mm in diameter and less than 700mm in depth, but becomes extremely difficult for holes exceeding these specifications. Machining large-diameter holes involves significant cutting torque, making it difficult for the operator to grip the drill handle, frequently resulting in injuries from the drill handle striking the operator, and in severe cases, even throwing the operator off the workpiece. Furthermore, this work is extremely physically demanding, involving continuous fatigue and is highly unsafe. When the machining depth exceeds 800mm, manual drilling is prone to deviation. Often, marking lines at both ends and then drilling from the other end is used. However, this deviation during single-end drilling creates misaligned steps during penetration, compromising both the straightness of the hole and its perpendicularity to the workpiece end face. This can create resistance during molten iron and slag discharge in smelting, affecting the user's performance. Summary of the Invention

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please refer to Figures 1 to 7 This utility model provides a graphite carbon brick drilling device, including a base 01, a power unit 02, a drilling self-water inlet connection unit 03, a drilling assembly 04, a carbon brick support device 05, and a carbon brick pressing device 06.

[0031] The power unit 02 is mounted on the base 01; the power unit 02 can be a drilling machine or a machine tool, and its chuck can be used to fix the drilling self-water inlet connection 03.

[0032] The drilling self-inlet water inlet connection part 03 is installed at one end of the output end of the power unit 02 and at the other end of the drilling assembly 04. The drilling assembly 04 and the drilling self-inlet water inlet connection part 03 are coaxial. This allows the power unit 02 to drive the drilling assembly 04 and the drilling self-inlet water inlet connection part 03 to rotate synchronously. The structure and working principle of the drilling self-inlet water inlet connection part 03 are existing technologies. Please refer to the content of the utility model patent with application number 201721053331.7. It will not be described in detail here.

[0033] The carbon brick support device 05 includes a height adjustment mechanism 51 and a lateral adjustment mechanism 52. The height adjustment mechanism 51 is installed on the base 01, and the lateral adjustment mechanism 52 is installed on the top of the height adjustment mechanism 51. The opening position of the carbon brick can be adjusted to face the drilling assembly 04 through the height adjustment mechanism 51 and the lateral adjustment mechanism 52.

[0034] Among them, the carbon brick pressing device 06 can press the carbon brick that needs to be drilled onto the top of the horizontal adjustment mechanism 52 from above to prevent the carbon brick from moving.

[0035] In use, the carbon brick can be hoisted to the top of the horizontal adjustment mechanism 52 by a crane or overhead crane, ensuring that the opening end face of the carbon brick is directly opposite the end of the drilling assembly 04. The carbon brick clamping device 06 is then activated, which clamps the carbon brick to be drilled onto the top of the horizontal adjustment mechanism 52 from above, preventing the carbon brick from moving. Then, by adjusting the height adjustment mechanism 51 and the horizontal adjustment mechanism 52, the opening position of the carbon brick can be adjusted to a suitable position directly opposite the drilling assembly 04 in two dimensions, so that the end of the drilling assembly 04 is accurately aligned with the position to be drilled. When drilling large carbon blocks, it is possible to achieve a single-pass drilling from one side of the carbon block, ensuring the drilling accuracy of the carbon block.

[0036] In one embodiment, the height adjustment mechanism 51 includes a hydraulic cylinder 511 and a support platform 512. The hydraulic cylinder 511 is longitudinally mounted in a receiving groove on the base 01, and the support platform 512 is fixed to the top of the hydraulic cylinder 511. Of course, the hydraulic cylinder 511 can be extended or retracted via a hydraulic power unit or hydraulic system to adjust the height of the support platform 512. It should be noted that the control of the hydraulic cylinder 511 is prior art and will not be described further here.

[0037] In one embodiment, to reduce the impact of the weight hydraulic cylinder 511 when the height adjustment mechanism 51 falls, a buffer assembly 53 is installed on the base 01 below the four corners of the support platform 512.

[0038] Specifically, the buffer assembly 53 includes a fixed sleeve 531, a movable sleeve 532, and a spring 533. The fixed sleeve 531 is mounted on the base 01. The movable sleeve 532 slides along the upper end of the fixed sleeve 531 and is fitted inside the fixed sleeve 531. The lower end of the spring 533 is connected to the bottom inside the fixed sleeve 531, and the upper end of the spring 533 is connected to the top inside the movable sleeve 532. When the hydraulic cylinder 511 retracts, causing the support platform 512 to fall, the support platform 512 will press down on the movable sleeve 532. Under pressure, the movable sleeve 532 can slide down along the fixed sleeve 531 to squeeze the spring 533, thus achieving buffering when the height adjustment mechanism 51 descends. Of course, there is another way of using it. When carbon bricks are placed on the lateral adjustment mechanism 52, if the pressure of the hydraulic cylinder 511 becomes unstable, the buffer assembly 53 can be used to buffer the falling carbon bricks, reducing the impact on the hydraulic cylinder 511 and providing protection.

[0039] An air hole 534 is provided at the lower part of the fixed sleeve 531. To increase the cushioning and protection effect, compressed air can be introduced into the fixed sleeve 531 and the movable sleeve 532 through the air hole 534 via a hose, and the high-pressure air can be used to offset part of the falling impact force.

[0040] In one embodiment, the lateral adjustment mechanism 52 includes a guide rail 521, a holding slot 522, and an adjusting rod 523. The guide rail 521 is fixed to the top of the support platform 512 in a direction perpendicular to the axis of the drilling assembly 04. The holding slot 522 is slidably mounted on the guide rail 521. The adjusting rod 523 is rotatably mounted on the support platform 512 along the extension direction of the guide rail 521. A moving block 524 is threaded onto the adjusting rod 523. The upper end of the moving block 524 passes through the support platform 512, so that when the adjusting rod 523 moves the moving block 524, it can simultaneously move the holding slot 522 along the guide rail 521, thereby adjusting the lateral position of the carbon block. The rotation of the adjusting rod 523 can be driven by a variable frequency motor or a handwheel.

[0041] Accordingly, in order to ensure the linear and stable movement of the moving block 524, a guide hole 513 is provided on the support platform 512 along the extension direction of the guide rail 521 for the moving block 524 to pass through.

[0042] In one embodiment, to prevent wastewater generated during drilling from overflowing from the holding tank 522 and scattering onto the processing table, a water collection tank 54 is provided on the side of the holding tank 522 facing the drilling assembly 04. The water collection tank 54 is connected through a drain hole 541, and the bottom of the water collection tank 54 is sloped, allowing the discharged wastewater to concentrate at the lower end of the water collection tank 54. Correspondingly, a drain pipe 542 is provided at the lowest point of the bottom of the water collection tank 54, so that the wastewater can be quickly discharged from the water collection tank 54. The drain pipe 542 can be connected to a wastewater collection tank, and after the wastewater is clarified, it can be reused for drilling, thereby improving the wastewater utilization efficiency.

[0043] In one embodiment, the drilling assembly 04 includes a hollow drill rod 41 and a drill bit 42; the drill bit 42 is tubular and has a through hole at its bottom; the end of the hollow drill rod 41 is threaded to the drilling self-inlet connection part 03, and the other end of the hollow drill rod 41 is threaded to the through hole, so as to realize the detachable connection of the hollow drill rod 41 for easy replacement.

[0044] Of course, in order to improve the quality and efficiency of drilling, grooves 43 are evenly distributed around the end of the drill bit 42. The grooves 43 have a Y-shaped structure, which can ensure the scraping of low carbon blocks of the drill bit 42, and at the same time facilitate the discharge of drilling residue mixed with wastewater during drilling.

[0045] In one embodiment, the carbon brick clamping device 06 includes a hoist 61 and a counterweight 62; the hoist 61 is disposed on one side of the base 01, and the counterweight 62 is suspended on the hoist 61 by a wire rope. The hoist 61 may be an electric hoist.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
