Description

Technical Field

[0001] This invention relates to the field of smelting technology, and more specifically to a tapping machine for a ferrosilicon furnace. Background Technology

[0002] The furnace front operation process in ferrosilicon furnace smelting production is not only characterized by high temperature, but also by a large amount of dust and noise, making it the most labor-intensive and dangerous process in the smelting production process.

[0003] Currently, the equipment for operating in front of the ferrosilicon furnace is not fully functional. It can realize automated operation of opening and blocking the furnace, but processes such as opening and sampling still require manual operation.

[0004] Pulling the hole, or guiding the flow, requires 3-4 operators to quickly pull the steel rod or wooden rod back and forth inside the furnace hole when the molten iron is not flowing smoothly. This process is labor-intensive, involves high ambient temperature, and is accompanied by hot slag splashing, posing a risk of burns. In addition, the high temperature of the molten iron can cause the rod to melt or deform due to high temperature, so the rod needs to be replaced frequently during the pulling process.

[0005] The sampling process involves three operators holding sampling spoons (made of a 40mm diameter steel rod with a graphite spoon at the end) and inserting the tip into the furnace opening to take out a sample of molten ferrosilicon. The sampling spoon is then manually rotated and poured into a mold. During this process, the workers are close to the furnace opening and are at risk of burns.

[0006] As can be seen from the above, opening, pulling, sampling, and plugging the holes are important procedures in the ferrosilicon tapping process. Currently, these procedures are still performed manually, and there is an urgent need for a ferrosilicon tapping equipment that can complete these procedures. Summary of the Invention

[0007] The purpose of this invention is to provide a tapping machine for ferrosilicon furnaces.

[0008] This invention is implemented by the following technical solution: A furnace tapping machine for a ferrosilicon furnace includes a longitudinal track, a traveling trolley that moves along the longitudinal track, a support platform that moves along the traveling trolley, a rotatable mechanism that rotates on the support platform, a connecting frame that is obliquely fixed to the upper surface of the rotatable mechanism, the top of the connecting frame that is hinged to the bottom surface of a moving arm, the upper surface of the rotatable mechanism that is hinged to the bottom of a first hydraulic cylinder, the piston rod of the first hydraulic cylinder that is hinged to the bottom surface of the moving arm, a rock drill and a plugging car that move along the moving arm, the head of the rock drill's chisel rod having an external thread and being internally threaded to one end of a connecting sleeve, the connecting sleeve being engaged in a slot on a tool holder, and a mud-pumping cylinder being installed inside the plugging car, the output end of the mud-pumping cylinder being fixedly connected to a barrel.

[0009] Preferably, two transverse sliding rods are arranged parallel to each other inside the vehicle body of the traveling trolley, and two through holes are symmetrically opened on the support platform. The two transverse sliding rods are respectively inserted into the two through holes. A second hydraulic cylinder is fixed inside the vehicle body of the traveling trolley, and the piston rod of the second hydraulic cylinder is hinged to the bottom surface of the support platform.

[0010] Preferably, the rotary mechanism is braked by a first bidirectional drive motor.

[0011] Preferably, a first chain and a second chain are rotatably provided on both sides of the movable arm, the rock drill is fixedly connected to the first chain, and the plugging car is fixedly connected to the second chain. The first chain and the second chain are braked by a second bidirectional drive motor and a third bidirectional drive motor, respectively.

[0012] Preferably, the connecting sleeve has two symmetrical notches, and two limiting rings are fixed on the connecting sleeve; the tool frame is composed of three support frames, each support frame has multiple support plates fixed on it, and the support plates have slots. The two notches of the connecting sleeve are inserted into the slots on the tool frame, so that the connecting sleeve and the slots are engaged, and the two limiting rings are located on the front and rear sides of the support plate.

[0013] Preferably, the eye-opening tool includes the connecting sleeve and the coaxially connected drill rod.

[0014] Preferably, the eye-pulling tool includes a connecting sleeve and a wooden rod: the other end of the connecting sleeve has multiple threaded holes on its circumferential surface, and a clamping bolt is threaded through the threaded holes; a portion of the wooden rod is inserted through the other end of the connecting sleeve and clamped and fixed by the clamping bolt.

[0015] Preferably, the sampling tool includes a connecting sleeve and a sampling spoon. The circumferential surface of the other end of the connecting sleeve is provided with multiple threaded holes. A clamping bolt is threaded through the threaded holes. The handle of the sampling spoon is inserted through the other end of the connecting sleeve and clamped and fixed by the clamping bolt.

[0016] Preferably, a mud-feeding trough is provided on one side of the barrel, and an arc-shaped cover plate is rotatably provided at the top of the mud-feeding trough.

[0017] Advantages of this invention: By setting the traveling trolley to move back and forth on the longitudinal track and the support platform to move left and right on the traveling trolley, the position adjustment of the moving arm can be realized. At the same time, the angle of the moving arm can be adjusted through the rotary mechanism and the first hydraulic cylinder. The rock drill and the plugging car are mounted on the moving arm. The drill rod of the rock drill can be rotated and cooperated with the tool frame to realize the quick replacement of the opening tool, the pulling tool and the sampling tool. After replacement, the position of the moving arm is adjusted to align with the furnace hole. The opening tool, the pulling tool and the sampling tool are driven by the rock drill to realize the opening, pulling and sampling operations. By moving the position of the moving arm left and right, the position of the plugging car and the rock drill can be switched, which makes it easy for the mud-pumping cylinder to push the drilling mud into the furnace hole to complete the plugging operation.

[0018] This solution effectively replaces manual labor in opening, pulling, sampling, and plugging eyes. It is safe and reliable, reduces material consumption, lowers labor costs, and reduces the intensity of labor. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 10 As shown, a furnace tapping machine for a ferrosilicon furnace includes a longitudinal track 1, on which a rack (shown in the figure) is fixed. A rotating gear inside a traveling trolley 2 meshes with the rack, allowing the traveling trolley 2 to move back and forth on the longitudinal track 1. Two transverse slide rods 2.1 are arranged parallel to each other inside the traveling trolley 2. Two through holes 3.1 are symmetrically opened on a support platform 3, with the two transverse slide rods 2.1 passing through the two through holes 3.1 respectively. A second hydraulic cylinder 2.2 is fixed inside the traveling trolley 2, and the piston rod of the second hydraulic cylinder 2.2 is hinged to the bottom surface of the support platform 3. This allows the support platform 3 to move left and right on the traveling trolley 2 for switching work positions. A slewing mechanism 4 is rotatably mounted on the support platform 3. A connecting frame 5 is fixedly inclined on the upper surface of the slewing mechanism 4. The top of the connecting frame 5 is hinged to the bottom surface of the moving arm 7. The upper surface of the slewing mechanism 4 is hinged to the bottom of the first hydraulic cylinder 6. The piston rod of the first hydraulic cylinder 6 is hinged to the bottom surface of the moving arm 7. The slewing mechanism 4 is existing technology, and its specific structure will not be described in detail. It is braked by the first bidirectional drive motor 4.1. The slewing mechanism 4 and the first hydraulic cylinder 6 enable the moving arm 7 to swing up, down, left, and right, which facilitates angle adjustment during operation.

[0023] To facilitate the opening, pulling, sampling, and plugging operations during the ferrosilicon tapping process, a first chain 7.1 and a second chain 7.2 are rotatably mounted on both sides of the moving arm 7. Sprockets (not shown in the figure) are rotatably connected to the first chain 7.1 and the second chain 7.2 at their corresponding front and rear positions on the moving arm 7. A rock drill 8 is fixedly connected to the first chain 7.1, and a plugging cart 9 is fixedly connected to the second chain 7.2. The first chain 7.1 and the second chain 7.2 are braked by a second bidirectional drive motor 8.1 and a third bidirectional drive motor 9.1, respectively. The output shaft of the second bidirectional drive motor 8.1 is coaxially and fixedly connected to the corresponding drive sprocket of the first chain 7.1, and the third bidirectional drive motor 9.1 is coaxially and fixedly connected to the corresponding drive sprocket of the second chain 7.2, allowing the rock drill 8 and the plugging cart 9 to move on the moving arm 7.

[0024] The eye-opening tool consists of a connecting sleeve 10 and a drill rod 14, with the drill rod 14 fixed to the other end of the connecting sleeve 10.

[0025] The eye-pulling tool consists of a connecting sleeve 10 and a wooden rod 15. The circumferential surface of the other end of the connecting sleeve 10 is provided with multiple threaded holes 10.3. A clamping bolt 10.4 is threaded through the threaded hole 10.3, so that wooden rods 15 of different diameters can be inserted into the connecting sleeve 10. Part of the wooden rod 15 is inserted into the other end of the connecting sleeve 10 and clamped and fixed by the clamping bolt 10.4.

[0026] The sampling tool consists of a connecting sleeve 10 and a sampling spoon 16. The circumferential surface of the other end of the connecting sleeve 10 is provided with multiple threaded holes 10.3. A clamping bolt 10.4 is threaded through the threaded hole 10.3. The handle of the sampling spoon 16 is inserted through the other end of the connecting sleeve 10 and clamped and fixed by the clamping bolt 10.4.

[0027] To facilitate quick replacement of the drilling tool, pulling tool, and sampling tool, a tool rack 11 is required. When the drilling tool, pulling tool, and sampling tool are placed on the tool rack 11, the center lines of the drill rod 14 of the drilling tool, the wooden rod 15 of the pulling tool, the handle of the sampling spoon 16 of the sampling tool, and the chisel rod of the rock drill 8 are coplanar. This ensures that the head of the chisel rod of the rock drill 8 can be inserted into the connecting sleeve 10 for threaded connection.

[0028] The tool holder 11 consists of three support frames, each with multiple support plates 11.1 fixed on it. Each support plate 11.1 has a slot 11.11, into which the connecting sleeve 10 is engaged. The drilling tool, pulling tool, and sampling tool all include the connecting sleeve 10. The connecting sleeve 10 has two symmetrical notches 10.1, and two limiting rings 10.2 are fixed on it. The two notches 10.1 of the connecting sleeve 10 are inserted into the slots 11.11 on the tool holder 11, ensuring that while the connecting sleeve 10 and the slots 11.11 are engaged, the two limiting rings 10.2 are positioned on the front and rear sides of the support plate 11.1 to prevent the connecting sleeve 10 from moving freely. When changing tools, the head of the rock drill 8's chisel is rotated and simultaneously inserted into the connecting sleeve 10 for a quick threaded connection.

[0029] The head of the rock drill 8 has an external thread and is connected to the internal thread of one end of the connecting sleeve 10. The rock drill 8 is manufactured by Guilin Fangxing Machinery Co., Ltd., model TFYY350-R48 left-handed. It has an external rotating chisel mechanism inside, which can independently drive the head of the chisel to rotate, so as to facilitate quick internal thread connection with one end of the connecting sleeve 10 and realize quick replacement of the opening tool, the pulling tool and the sampling tool.

[0030] The plugging machine 9 is equipped with a mud-removing cylinder 12, which is manufactured by Shanxi Jiuhe Zhongtai Machinery Equipment Co., Ltd., model G100X80X16300. The output end of the mud-removing cylinder 12 is fixedly connected to a barrel 13. A mud-feeding trough 13.1 is opened on one side of the barrel 13, and an arc-shaped cover plate 13.2 is rotatably installed at the top of the mud-feeding trough 13. Before plugging, the arc-shaped cover plate 13.2 is opened to fill the mud into the mud-feeding trough 13.1. Then the arc-shaped cover plate 13.2 is closed, and the piston rod of the mud-removing cylinder 12 pushes the mud into the furnace hole to complete the plugging operation.

[0031] Working principle: During the drilling operation, the traveling trolley 2 moves at the front end of the longitudinal track 1. The second hydraulic cylinder 2.2 controls the left and right movement of the support platform 3 to adjust the position of the moving arm 7. The first hydraulic cylinder 6 adjusts the angle of the drilling tool to align with the furnace hole. Finally, the second bidirectional drive motor 8.1 drives the rock drill 8 to move on the moving arm 7 to the furnace hole and starts the rock drill 8 to move back and forth quickly to realize the drilling work until the drill rod 14 opens the furnace hole and the molten iron flows out. During the drilling operation, the traveling trolley 2 moves to the tool rack 11. By adjusting the position of the moving arm 7, the drilling tool is placed on the support frame. The external reversing and rotating mechanism inside the rock drill 8 is then activated to reverse. Simultaneously, the rock drill 8 moves backward and, under the limit of the slot 13.1 on the tool rack 13, the head of the rock drill 8's chisel and one end of the connecting sleeve 10 of the drilling tool are quickly unscrewed. Then, the second hydraulic cylinder 2.2 controls the left and right movement of the support platform 3 to adjust the position of the moving arm 7, aligning the head of the rock drill 8's chisel with one end of the connecting sleeve 10 of the drilling tool. The external reversing and rotating mechanism inside the rock drill 8 is then activated to reverse. Simultaneously, the rock drill 8 moves forward and, under the limit of the slot 13.1 on the tool holder 13, the head of the rock drill 8 and one end of the connecting sleeve 10 of the hole-pulling tool are quickly threaded and fixed. Then, the traveling trolley 2 moves to the front end of the longitudinal track 1, and the position of the moving arm 7 is adjusted by controlling the left and right movement of the support platform 3 through the second hydraulic cylinder 2.2. The angle of the hole-pulling tool is adjusted by the first hydraulic cylinder 6 to align with the furnace hole. Finally, the second bidirectional drive motor 8.1 drives the rock drill 8 to move on the moving arm 7 to the furnace hole, and starts the rock drill 8 to move back and forth quickly to realize the hole-pulling work until the flow rate of the furnace hole increases to the target value.

[0032] During sampling, the traveling trolley 2 moves to the tool rack 11. By adjusting the position of the moving arm 7, the drilling tool is placed on the support frame. The external rotation and chisel-turning mechanism inside the rock drill 8 is then activated to reverse, and the rock drill 8 moves backward. Under the limit of the slot 13.1 on the tool rack 13, the head of the rock drill 8's chisel rod and one end of the connecting sleeve 10 of the drilling tool are quickly unscrewed. Then, the second hydraulic cylinder 2.2 controls the left and right movement of the support platform 3 to adjust the position of the moving arm 7, so that the head of the rock drill 8's chisel rod is aligned with one end of the connecting sleeve 10 of the sampling tool. The external rotation and chisel-turning mechanism inside the rock drill 8 is then activated to rotate forward, and the rock drill 8 moves forward. Under the limit of the slot 13.1 on the tool rack 13, the head of the rock drill 8's chisel rod... One end of the connecting sleeve 10 of the head and sampling tool is quickly threaded and fixed; then the traveling trolley 2 is moved to the front end of the longitudinal track 1, and the position of the moving arm 7 is adjusted by controlling the left and right movement of the support platform 3 through the second hydraulic cylinder 2.2, and the angle of the sampling tool is adjusted by the first hydraulic cylinder 6 to align with the furnace hole. Finally, the second bidirectional drive motor 8.1 drives the rock drill 8 to move on the moving arm 7 to the furnace hole to realize the sampling work. After sampling, the moving arm 7 moves backward, and at the same time, the position of the sampling spoon 16 is adjusted by the rotary mechanism 4 and the first hydraulic cylinder 6 to place it above the sampling mold 17. The external rotary chisel mechanism inside the rock drill 8 is started to rotate forward, so that the sampling spoon 16 rotates to pour molten iron into the sampling mold 17, completing the sampling process and waiting for subsequent sample testing.

[0033] During the plugging operation, the prepared taphole clay is filled into the taphole 13. The traveling trolley 2 moves at the front end of the longitudinal track 1. The second hydraulic cylinder 2.2 controls the left and right movement of the support platform 3 to adjust the position of the moving arm 7. The first hydraulic cylinder 6 adjusts the angle of the opening tool to align with the furnace hole. Finally, the third bidirectional drive motor 9.1 drives the plugging trolley 9 to move on the moving arm 7 to the furnace hole, and starts the mud-pushing cylinder 12 to push the taphole clay into the furnace hole, completing the plugging operation.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
