DETAILED DESCRIPTION
[0015] like Figure 1-3 As shown: A high carbon steel alloy furnace opening machine includes a track 1, which is an I-beam and extends left and right. There are three hangers 3 below the track 1. The hangers 3 are U-shaped. Both ends of the upper part of the hanger 3 are rotatably connected to pulleys 2. The pulleys 2 are slidably engaged with the track 1. The lower end of the hanger 3 is rotatably connected to a height adjustment mechanism 4. The lower ends of the two height adjustment mechanisms 4 on the left are fixedly connected to a lifting ring 5. The left part of the bracket 6 is fixedly connected to a crossbeam 49. The crossbeam 49 is fixedly connected to the two lifting rings 5. The right part of the bracket 6 is hook-shaped. The top of the right end of the bracket 6 is fixedly connected to a horizontal rod 50. The horizontal rod 50 is fixedly connected to the fixing seat 1 7 and the fixing seat 2 10, and the fixing seat 1 7 and the fixing seat 2 10 are clearance-fitted, and the fixing seat 2 10 is located on the right side of the fixing seat 1 7, and the lower end of the right height adjustment mechanism 4 is fixedly connected with a link 8, and the lower end of the link 8 is hung with a hanging block 9, and the hanging block 9 is fixedly connected to the top of the fixing seat 2 10, and the push rod 11 passes through the fixing seat 1 7 and the fixing seat 2 10 from left to right, and the push rod 11 is fixedly connected to the fixing seat 1 7 and the fixing seat 2 10, and the right end of the push rod 11 is fixedly installed with a motor 12, and the right end of the output shaft of the motor 12 is fixedly connected with a high-carbon steel alloy drill bit 13.
[0016] The height adjustment mechanism 4 includes a sleeve 41, and the inner walls of the upper and lower ends of the sleeve 41 are fixedly connected with connecting nuts 42. The upper and lower ends of the sleeve 41 are respectively fixedly connected with two connecting nuts 42, and the upper and lower connecting nuts 42 are respectively connected with an upper threaded rod 43 and a lower threaded rod 44. The upper threaded rod 43 and the lower threaded rod 44 are threadedly matched with the upper and lower connecting nuts 42 respectively. The thread directions of the upper threaded rod 43 and the lower threaded rod 44 are opposite. The outer walls of the upper threaded rod 43 and the lower threaded rod 44 are threadedly connected with locking nuts 45, and the locking nuts 45 are tightly pressed against the connecting nuts 42. The top of the upper threaded rod 43 is fixedly connected with an upper connecting rod 46, and the upper connecting rod 46 is fixedly connected to the bottom end of the hanger 3. The bottom end of the lower threaded rod 44 is fixedly connected with a lower connecting rod 47, and the lower connecting rod 47 is respectively connected to the lifting ring 5 and the link 8.
[0017] An adjustment hole 48 is defined in the middle of the outer wall of the sleeve 41 , and the adjustment hole 48 vertically passes through the sleeve 41 .
[0018] Place the high carbon steel alloy furnace opening machine at the location where the furnace needs to be opened, and ensure that track 1 is stable and fixed.
[0019] The height of the hanger 3 can be adjusted as needed by rotating the sleeve 41 in the height adjustment mechanism 4. Since the thread directions of the upper threaded rod 43 and the lower threaded rod 44 are opposite, the two will move away from or closer when the sleeve 41 is rotated. The upper threaded rod 43 and the lower threaded rod 44 are fixed in the adjusted position by the locking nut 45.
[0020] Adjust the position of the high carbon steel alloy drill bit 13. By hanging the link 8 and fixing the hanging block 9, the position of the drill bit can be fine-tuned to a certain extent to ensure that it is aligned with the furnace mouth.
[0021] When the furnace is opened, the motor 12 is started, and the output shaft of the motor 12 drives the high-carbon steel alloy drill bit 13 to rotate, pushing the push rod 11, so that the high-carbon steel alloy drill bit 13 gradually approaches and contacts the furnace mouth. Due to the high hardness and wear resistance of the high-carbon steel alloy drill bit 13, it can quickly and effectively drill into the molten pool in the furnace. As the drill bit goes deeper, the molten iron in the furnace begins to flow out.
[0022] When the molten iron flows out to the required amount, the motor 12 is turned off, the rotation of the drill bit is stopped, the push rod 11 is slowly withdrawn, and the high carbon steel alloy drill bit 13 is taken out of the furnace.
[0023] According to the need, adjust the height of the hanger 3 and the position of the drill bit to prepare for the next furnace opening. This utility model only protects the mechanical part, and the functions realized by the software control part are not within the protection scope of this utility model.
