[0025] Refer to Figures 1-6, A hoisting device for a smelting furnace, including a triangular beam 1. Support feet 4 are welded to the three ends of the triangular beam 1. Universal wheels 7 are fixed to the bottom ends of the support feet 4 by bolts. A transverse movement mechanism 3 for the hoisting positions of smelting furnaces with different sizes is provided at the bottom of the triangular beam 1. A winding assembly with a hook 5 is hung at the bottom of the transverse movement mechanism 3. The hook 5 is used to hang the smelting furnace. Limiting mechanisms 6 for smelting furnaces with different sizes and adaptively adjusting the limiting sizes are provided on one side of each of the three support feet 4. Through the triangular structure of the triangular beam 1, the hook 5 hangs and hoists the smelting furnace from three directions, thus effectively improving the stability during the hoisting of the smelting furnace.

[0026] The limiting mechanism 6 in the present invention includes a side mounting frame 19. The side mounting frame 19 is welded to one side of the support foot 4. A flipping support frame 25 is hinged inside the side mounting frame 19. An inner rubber pressing pad 33 is bonded to the bottom end of the flipping support frame 25. A plurality of equally spaced pin holes 26 are formed on one side of the flipping support frame 25. A rotating shaft 23 is fixed to one side of the support foot 4 by bolts. A support rod 24 is rotatably connected to one side of the rotating shaft 23. A threaded hole 20 is formed at the end of the support rod 24. A screw 22 is threadedly connected to the threaded hole 20. One end of the screw 22 can be inserted into the pin hole 26. The other end of the screw 22 is fixed with two toggle levers 21 by bolts, and the two toggle levers 21 are arranged oppositely. By rotating the flipping support frame 25 outward around the side mounting frame 19, the inner rubber pressing pad 33 provided at the end of the flipping support frame 25 presses the smelting furnace. Since there are three groups of flipping support frames 25, the smelting furnace can be limited and fixed from three directions. Then, by pulling the rotating support rod 24 inward around the rotating shaft 23 to a proper position, and then rotating the screw 22, the screw 22 is rotated and inserted into one of the pin holes 26 formed on the side of the flipping support frame 25, so that the flipping support frame 25 is supported and fixed.

[0027] Both sides of the bottom end of the flipping support frame 25 in the present invention are welded with support rods 32. The end of the support rod 32 is rotatably connected with a rotating sleeve 31. An extrusion sliding rod 29 is inserted into the rotating sleeve 31. One end of the extrusion sliding rod 29 is welded with a pinch plate 27. The other end of the extrusion sliding rod 29 is bonded with a side rubber pressing pad 30. A tension spring 28 is adjusted on one side of the extrusion sliding rod 29, and both ends of the tension spring 28 are fixed to the pinch plate 27 and the rotating sleeve 31 respectively. By pulling the pinch plate 27 to move the extrusion sliding rod 29 and stretch the tension spring 28, and then rotating the rotating sleeve 31 around the support rod 32 to a proper angle, the support rod 32 contacts the smelting furnace through the side rubber pressing pad 30, and the support rod 32 presses the smelting furnace through the tension of the tension spring 28, so as to assist in the secondary fixation of the smelting furnace.

[0028] The transverse movement mechanism 3 in the present invention includes a transverse movement frame 14. Both inner walls of the transverse movement frame 14 are rotatably connected to two driving wheels 13 through bearings. The driving wheels 13 are hung in the T-shaped groove 8 opened in the triangular beam 1. One outer wall of the transverse movement frame 14 is fixedly bolted with a transverse movement motor 12, and one end of the output shaft of the transverse movement motor 12 passes through the transverse movement frame 14 and is fixed to one of the driving wheels 13. A locking mechanism 2 for fixing its position is provided on the transverse movement frame 14. The locking mechanism 2 includes an upper mounting frame 18. The upper mounting frame 18 is fixedly bolted to the top of the transverse movement frame 14. A plurality of equally spaced locking holes 15 are opened at the top of the triangular beam 1. A locking frame 17 is inserted into the top of the upper mounting frame 18. The bottom end of the locking frame 17 can be inserted into the locking hole 15. A cylinder 16 is fixedly bolted to the outer wall of the top of the upper mounting frame 18, and one end of the piston rod of the cylinder 16 is fixed to the locking frame 17. A winding box is hung at the bottom of the transverse movement frame 14. A winding roller 9 is provided in the winding box. One side of the winding roller 9 is wound with a chain 11, and the end of the chain 11 is fixed to the hook 5. A winding motor 10 is fixedly bolted to one outer wall of the winding box, and one end of the output shaft of the winding motor 10 passes through the winding box and is fixed to the winding roller 9. The end of the hook 5 is hinged with a spring buckle. By starting the transverse movement motor 12, the transverse movement motor 12 rotates to drive the driving wheel 13 to rotate, and the driving wheel 13 moves along the T-shaped groove 8 opened in the triangular beam 1, so as to adjust the position of the hook 5, facilitating the hanging of melting furnaces of different sizes and models. At the same time, by starting the cylinder 16, the cylinder 16 shortens to drive the locking frame 17 to move downward and insert into one group of locking holes 15, thereby completing the locking and fixing of the position of the transverse movement frame 14, effectively avoiding the risk of the transverse movement frame 14 sliding during the hoisting of the melting furnace, causing the melting furnace to tip over and fall, etc.

[0029] When the present invention is in use, it is divided into the following steps: S1: By starting the transverse movement motor 12, the transverse movement motor 12 rotates to drive the driving wheel 13 to rotate, and the driving wheel 13 moves along the T-shaped groove 8 opened in the triangular beam 1, so as to adjust the position of the hook 5, facilitating the hanging of melting furnaces of different sizes and models. At the same time, by starting the cylinder 16, the cylinder 16 shortens to drive the locking frame 17 to move downward and insert into one group of locking holes 15, thereby completing the locking and fixing of the position of the transverse movement frame 14. Then, by starting the winding motor 10, the winding motor 10 completes the hoisting of the hook 5 and the melting furnace through the winding roller 9 and the chain 11, effectively avoiding the risk of the transverse movement frame 14 sliding during the hoisting of the melting furnace, causing the melting furnace to tip over and fall, etc. Moreover, due to the triangular structure of the triangular beam 1, the hook 5 hangs and hoists the melting furnace from three directions, thereby effectively improving the stability during the hoisting of the melting furnace; S2: Then, by rotating the tipping bracket 25 outward around the side mounting bracket 19, the inner rubber pressing pad 33 provided at the end of the tipping bracket 25 presses against the smelting furnace. Since there are three groups of tipping brackets 25, the smelting furnace can be limited and fixed from three directions. Then, by pulling the rotating strut 24 inward around the rotating shaft 23 to a proper position, and then rotating the screw 22, the screw 22 is rotated and inserted into one of the pin holes 26 opened on the side of the tipping bracket 25, so that the tipping bracket 25 is supported and fixed. S3: Then, by pulling the pinch plate 27, the extrusion slide rod 29 is moved and the tension spring 28 is elongated. Then, the rotating sleeve 31 is rotated around the support rod 32 to a proper angle, so that the support rod 32 contacts the smelting furnace through the side rubber pressing pad 30, and the support rod 32 presses against the smelting furnace by the tension of the tension spring 28, thereby assisting in the secondary fixation of the smelting furnace.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0031] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
