Description

Technical Field

[0001] This utility model relates to the field of slag removal, and in particular to a slag rake lifting wire rope swing guide device. Background Technology

[0002] Currently, cleaning the slag on the surface of molten aluminum in the holding furnace requires a dedicated slag-removing station, staffed by specialized personnel using slag rakes. This manual slag removal is in a harsh working environment, with workers exposed to high temperatures, heat radiation, and dust for extended periods, resulting in high labor intensity. In the event of a furnace explosion, molten aluminum splashes, posing even greater danger to operators. Consequently, more and more people are refusing this work, leading to recruitment difficulties, high staff turnover, and continuously increasing labor costs. Furthermore, manual slag removal is inefficient, and the quality is greatly affected by human factors, resulting in inconsistent product quality, scrap, and economic losses. Therefore, considering the environmental factors of slag removal operations, developing suitable automated equipment to replace manual slag removal is a pressing problem that needs to be solved in this industry.

[0003] Currently, the intelligent slag removal devices for holding furnaces disclosed in existing technologies are mainly used for slag removal in small holding furnaces. They are not suitable for holding furnaces with an internal width of 5m and a depth of 4m or more. The intelligent slag removal device cannot fully extend into the interior, especially when the temperature inside the holding furnace is above 750℃. The power devices, such as motors used to adjust the height and angle, cannot extend into the furnace, otherwise their service life will be short and they will not function properly. Therefore, the reasonable arrangement of the power devices and how to transmit power are very important. Announcement No. CN 214032549 U discloses a slag removal device for a blast furnace. This device includes a connecting rod, a slag rake, and a rake lifting mechanism. It mainly uses a steel wire rope to control the raising and lowering of the slag rake. Since the raising and lowering is directly controlled by the traction rope, when the slag rake swings left and right, the position of the traction point connected to the slag rake changes, causing the traction rope to loosen and the slag rake to descend. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a reasonably designed wire rope swing guide device for lifting a slag rake that can limit the position of the wire rope and ensure that the position of the wire rope remains unchanged when swinging left and right.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a swing guide device for the lifting wire rope of a slag rake, which is located between the slag rake and the slag rake frame. A rotating swing frame is installed at the end of the slag rake frame, which rotates left and right. The slag rake is installed on the rotating swing frame, and a lifting power device is installed on the slag rake frame. The output end of the lifting power device is connected to a lifting wire rope. The free end of the lifting wire rope extends forward along the slag rake frame and connects to the front of the slag rake. A wire rope guide is fixed on the rotating swing frame, which extends forward for the lifting wire rope to pass through. The wire rope guide is located above the slag rake.

[0006] As a preferred technical solution, the rotating frame is equipped with a reversing guide for the lifting steel wire rope to pass through, and the reversing guide corresponds to the rotation axis of the rotating frame.

[0007] As a preferred technical solution, the reversing guide includes two guide pulleys, which are connected to the rotating frame via pulley shafts, and a wire rope channel is formed between the two guide pulleys to limit the movement of the lifting wire rope.

[0008] As a preferred technical solution, the two guide pulleys are located on the left and right sides of the rotation axis of the rotating swing frame.

[0009] As a preferred technical solution, the reversing guide is a reversing guide ring fixed on the rotation shaft of the rotating frame, and the middle part of the reversing guide ring has a wire rope channel for limiting the lifting wire rope.

[0010] As a preferred technical solution, a guide wheel is provided at the front end of the wire rope guide, and the lifting wire rope passes around the guide wheel and connects downward to the slag rake.

[0011] As a preferred technical solution, the lifting power device includes a linear drive motor installed at the rear end of the slag removal beam, a linear slider on the linear drive motor reciprocates along the length of the slag removal beam, and the rear end of the lifting wire rope is connected to the linear slider.

[0012] As a preferred technical solution, the lifting power device includes a lifting power motor, the output end of which is connected to a take-up and undo reel, and the rear end of the lifting wire rope is wound around the take-up and undo reel.

[0013] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the wire rope guide is fixedly connected to the rotating swing frame, so when the rotating swing frame rotates, the wire rope guide will cause the lifting wire rope to rotate left and right, ensuring that the lifting wire rope can bend and swing left and right, and the length of the wire rope remains basically unchanged, without affecting the lifting height of the slag rake, resulting in better performance; this device, with the help of the wire rope guide and the reversing guide, and by coordinating the two with the rotating shaft of the rotating swing frame, further ensures that the lifting adjustment and the left and right angle adjustment of the slag rake do not interfere with each other, thus improving the slag removal effect of the slag rake. The structure is simple, the design is ingenious, and the cost is low. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, a swing guide device for the lifting wire rope of the slag rake is located between the slag rake frame 1 and the slag rake 2. The end of the slag rake frame 1 is equipped with a rotating swing frame 3 that rotates left and right. The slag rake 2 is mounted on the rotating swing frame 3 that rotates up and down. A lifting power device is installed on the slag rake frame 1. The output end of the lifting power device is connected to a lifting wire rope 4. The free end of the lifting wire rope 4 extends forward along the slag rake frame 1 and connects to the front of the slag rake 2. A wire rope guide 5 that extends forward for the lifting wire rope 4 to pass through is fixed on the rotating swing frame 3. The wire rope guide 5 is located above the slag rake 2.

[0024] The slag removal beam 1 is equipped with a wire rope protective tube 6 or a wire rope cover to guide the lifting wire rope 4 through. The wire rope protective tube 6 is located behind the rotating swing frame 3. It protects the wire rope on the one hand and guides the wire rope on the other hand, ensuring that the lifting wire rope 4 extends forward along the length direction of the slag removal beam 1.

[0025] In this embodiment, the wire rope guide 5 is a hollow wire rope conduit. The rear end of the wire rope conduit is indirectly fixed to the rotating swing frame 3 and close to the rotation axis of the rotating swing frame 3. The front end of the wire rope conduit extends forward to the front of the slag rake 2. The front end of the lifting wire rope 4 passes through the interior of the wire rope conduit and then extends out from the front end of the wire rope conduit, connecting downward to the front top of the slag rake 2.

[0026] The wire rope guide 5 extends forward along the length of the slag removal beam 1 and is indirectly fixed to the rotating swing frame 3. The wire rope guide 5 has two advantages: First, the wire rope guide 5 can guide and support the lifting wire rope 4, allowing the front end of the lifting wire rope 4 to extend forward smoothly. Compared with the connection method where the wire rope is directly connected to the front of the slag removal rake 2, the extension and guidance using the wire rope guide 5 can ensure a larger angle adjustment range for the slag removal rake 2. Second, the wire rope guide 5 is fixedly connected to the rotating swing frame 3. Therefore, when the rotating swing frame 3 rotates, the wire rope guide 5 will cause the lifting wire rope 4 to rotate left and right accordingly. When the lifting wire rope 4 bends and swings left and right, its wire rope length remains basically unchanged, which does not affect the lifting height of the slag removal rake 2, resulting in better performance. Of course, a wire rope guide rod can be used to replace the wire rope conduit. Several wire rope loops are provided on the surface of the wire rope guide rod. The lifting wire rope 4 passes through several wire rope loops in sequence. The several wire rope loops cooperate to guide and limit the lifting wire rope 4.

[0027] A support column is also provided between the wire rope guide 5 and the rotating swing frame 3.

[0028] In order to ensure that the lifting wire rope 4 can follow the direction of rotation well when the rotating pendulum 3 rotates, a reversing guide is installed on the rotating pendulum 3 for the lifting wire rope 4 to pass through. The reversing guide is located behind the wire rope guide 5 and corresponds to the rotation axis of the rotating pendulum 3.

[0029] The reversing guide includes two guide pulleys 6, which are connected to the rotating frame 3 via pulley shafts. The pulley shafts are vertically fixed directly or indirectly to the rotating frame 3. A wire rope channel is formed between the two guide pulleys 6 to limit the lifting wire rope 4. The two guide pulleys 6 cooperate to clamp the lifting wire rope 4. The two guide pulleys 6 are located on the left and right sides of the rotation axis of the rotating frame 3, ensuring that the lifting wire rope 4 can bend and turn at the rotation axis of the rotating frame 3. When the rotating frame 3 rotates, the lifting wire rope 4 is limited by the two guide pulleys 6. Therefore, the lifting wire rope 4 will bend and change direction after passing over the guide pulleys 6. This is equivalent to the lifting wire rope 4 rotating around the rotation axis of the rotating frame 3. This ensures that when the rotating frame 3 rotates, the lifting wire rope 4 can bend and swing left and right, with its length remaining basically unchanged. This does not affect the lifting height of the slag rake 2, resulting in better performance. Furthermore, the bending of the wire rope is supported by the guide pulleys 6, which reduces friction on the wire rope when the guide pulleys 6 change direction. Of course, the reversing guide can have two guide posts, and the lifting wire rope 4 passes between the two guide posts to ensure that the lifting wire rope 4 can bend along the rotation axis.

[0030] To further reduce the reversing friction of the wire rope, a reversing guide wheel 7 is provided at the front end outlet of the wire rope guide 5, and the lifting wire rope 4 passes around the reversing guide wheel 7 and connects downward to the slag rake 2.

[0031] The lifting power device includes a linear drive motor 8 installed at the rear end of the slag removal beam 1. A linear slider 9 on the linear drive motor 8 slides back and forth along the length of the slag removal beam 1. A lifting wire rope 4 is connected to the linear slider 9. The front end of the lifting wire rope 4 extends forward and connects to the front of the slag removal rake 2. The linear drive motor 8 is fixed to a fixed plate at the rear end of the slag removal beam 1. In use, the linear slider 9 slides back and forth along the linear drive motor 8, thereby driving the rear end of the lifting wire rope 4 forward or backward, pulling the rear end of the slag removal rake 2 to rotate up and down around the rotating swing frame 3, thus realizing the raising and lowering of the front end of the slag removal rake 2 and meeting the slag removal height adjustment requirements. Of course, the lifting power device can also be of other structures. For example, the lifting power device includes a lifting power motor, the output end of which is connected to a winding reel. The rear end of the lifting wire rope 4 is wound around the winding reel, and the winding and unwinding of the wire rope is realized by the rotation of the winding reel.

[0032] The rear end of the slag removal beam 1 is provided with a swing power component, which can drive the rotating swing frame 3 to rotate left and right through the swing transmission component; the front end of the slag removal beam 1 is fixed with a mounting base, which serves as a connecting base; a rotating shaft is fixed on the rotating swing frame 3, which is rotatably connected to the mounting base; and the swing transmission component is located on the mounting base to drive the rotating shaft to rotate.

[0033] The swing transmission assembly includes a worm gear 10 and a worm 11 that are coupled together. A rotating shaft 12 is fixed on the rotating frame 3, and the rotating shaft 12 is fixedly connected to the worm gear 10. The worm 11 is rotatably mounted on the mounting base of the slag-removing beam frame 1, and the worm 11 is also connected to the swing power assembly. The coupling of the worm gear 10 and the worm 11 has a self-locking function, ensuring the stability of the left and right angles. Furthermore, since the worm gear 10 and the worm 11 are mechanically driven, their entry into the holding furnace will not be affected.

[0034] The swing power assembly includes a geared motor 13 located at the rear end of the slag-removing beam 1 (the end furthest from the slag-removing rake 2). A sprocket 14 is mounted on the output shaft of the geared motor 13, and a second sprocket 15 is mounted on the worm gear 11. A chain 16 connects the first sprocket 14 and the second sprocket 15. The geared motor 13 is fixed to a fixed plate at the rear end of the slag-removing beam 1. During slag removal operations, the geared motor 13 is located outside the holding furnace and transmits power to the worm gear 11 and worm wheel 10 via the sprocket and chain 16, thereby achieving the left-right swing of the rotating swing frame 3 and the slag-removing rake 2.

[0035] The working principle of this embodiment is as follows:

[0036] Before the slag removal operation, the slag removal rake 2 does not swing and is raised to approximately the same height as the slag removal beam 1, so that it can be easily extended into the interior of the heat preservation furnace through the furnace opening. The linear drive motor 8 and the geared motor 13 are both located outside the heat preservation furnace.

[0037] When adjusting the height, the linear drive motor 8 drives the linear slider 9 to slide, thereby pulling the rear end of the slag rake 2 to rotate up and down around the rotating frame 3 via the lifting wire rope 4. This achieves the raising and lowering of the front end of the slag rake 2, meeting the slag rake height adjustment requirements. When adjusting the angle, the reduction motor 13 is activated, causing the worm gear 11 to rotate via the sprocket and chain. This causes the worm wheel 10, the rotating frame 3 fixed to the worm wheel 10, the wire rope guide 5, the reversing guide, the slag rake 2, and other structures to swing left and right together. At this time, the reversing guide and the wire rope guide 5 cooperate to limit the lifting wire rope 4, ensuring that the lifting wire rope 4 swings left and right along with the rotating shaft 12 without affecting the vertical height of the slag rake 2.

[0038] This device utilizes the wire rope guide 5 and the reversing guide, and designs them in conjunction with the rotating shaft 12 of the rotating frame 3. This allows the lifting wire rope 4 to stably follow the left and right swings, ensuring that the lifting adjustment and left and right angle adjustment of the slag rake 2 do not interfere with each other and do not affect each other, thereby improving the slag removal effect of the slag rake 2.

[0039] Example 2:

[0040] The main difference between Embodiment 2 and Embodiment 1 lies in the structure of the reversing guide. In this embodiment, see... Figure 5 The reversing guide is a reversing guide ring 17 fixed on the rotation shaft 12 of the rotating frame 3. The reversing guide ring 17 has a wire rope channel in the middle to limit the lifting wire rope 4.

[0041] The lifting wire rope 4 is fitted inside the reversing guide ring 17. When the rotating frame 3 rotates, the lifting wire rope 4 is limited by the reversing guide ring 17. Therefore, the lifting wire rope 4 will bend and change direction through the reversing guide ring 17. This is equivalent to the lifting wire rope 4 rotating around the rotation axis 12 of the rotating frame 3. This ensures that when the rotating frame 3 rotates, the lifting wire rope 4 can bend and swing left and right, and its length remains basically unchanged. This does not affect the lifting height of the slag rake 2, resulting in better performance.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
