Technical Field

[0001] The utility model relates to the field of smelting and pouring, in particular to a portable pouring ladle for two-sided pouring and a corresponding bracket. Background Art

[0002] In the process of using a ladle for casting, it is inevitable that the molten metal contains slag. As the use time increases, more and more slag will stick to the ladle mouth, resulting in the molten metal not being poured out completely. The molten metal remaining in the ladle affects the pouring temperature and even causes changes in trace elements, affecting the casting quality. In addition, the slag sticking to the ladle mouth will also cause the molten metal to be diverted, resulting in waste and affecting the pouring speed.

[0003] When there is too much slag on the ladle nozzle, it will seriously affect production. The nozzle is difficult to replace alone, and replacing the entire ladle not only involves the cost of repairing and baking the ladle, but also affects production during the waiting period, slowing down the production rhythm. At the same time, how to conveniently and safely realize the flipping and loading and unloading of the ladle is also a problem that needs to be solved in casting production. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a portable ladle for double-sided pouring and a corresponding bracket, which can be used for double-sided pouring, effectively prolonging the service life and reducing the cost of the ladle. At the same time, the matching bracket can also realize fast and convenient loading, unloading and flipping of the ladle, effectively ensuring the smooth progress of production.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a portable ladle for realizing double-sided pouring, the main body of which is cylindrical and includes an internal lining and an external shell, and symmetrical Y-shaped reinforcement plates of the same size are fixedly arranged on the left and right sides of the shell, branch fixing ears are respectively arranged at the two branches of the Y-shaped reinforcement plate, bottom fixing ears are arranged at the bottom, and lifting ears are fixedly arranged in the middle, and lifting rings are fixedly arranged in the middle of the bottom on the front and rear sides of the shell.

[0006] The further improvement of the technical solution of the utility model is that the cladding is made of steel, a plurality of air holes are arranged on the cladding, and the cladding lining is made of refractory material.

[0007] A corresponding bracket of a portable pouring ladle for two-sided pouring includes a base, support brackets of the same size and opposite positions are fixedly arranged on the left and right sides of the base, a flip frame is hinged on the support frame, a telescopic rod fixedly connected to the base is hinged on the flip frame, bracket side panels are fixedly arranged on the inner side of the flip frame, and wave-shaped grooves matching branch fixing ears, hanging ears and bottom fixing ears are arranged on the edges of the bracket side panels.

[0008] A further improvement of the technical solution of the utility model is that: between the bracket side plates on both sides, a bracket front plate is connected to the front side and a bracket bottom plate is connected to the bottom of the bracket front plate.

[0009] A further improvement of the technical solution of the utility model is that the front plate of the bracket is an arc-shaped plate adapted to the cylindrical enclosure.

[0010] A further improvement of the technical solution of the utility model is that both sides of the wave-shaped groove on the edge of the bracket side plate that matches the branch fixing ear and the wave-shaped groove that matches the bottom fixing ear are raised blocking parts for preventing the ladle from slipping.

[0011] A further improvement of the technical solution of the utility model is that the base is fixedly arranged on a trolley which can move on the rails.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is as follows: by setting the bracket on a rail trolley, the trolley is used to move on the track and carry the ladle on the ground, instead of the traditional use of an overhead crane to lift the ladle, which is safer and more precise. By symmetrically setting the lifting ears and fixing ears on both sides of the ladle, it is not only convenient for lifting and installation, but also can realize the use of the two sides of the mouthpiece for double-sided pouring, effectively extending the service life and reducing the cost of repairing and baking the ladle, and reducing the impact of changing the ladle on production continuity. By setting a wavy groove on the bracket, not only is the ladle stable, but also convenient for loading and unloading and installation, the blocking part on the groove cooperates with the outer lifting ring of the ladle to effectively prevent slipping accidents during flipping. By setting a telescopic rod on the bracket to achieve flipping, it is also more convenient and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the embodiments:

[0020] Embodiment 1:

[0021] like Figure 1 As shown, it is a schematic diagram of the structure of a portable ladle for two-sided pouring. The main body is cylindrical, with a lining 1 inside and a shell 2 outside. The main body of the lining 1 is a refractory material, which can be built with refractory bricks or cast with refractory materials. In this embodiment, two layers of magnesium-carbon refractory bricks are staggered. After the masonry is completed, it is placed at room temperature for more than 5 hours, baked with a low fire for more than 6 hours, and baked with a high fire for more than 10 hours. It is used immediately after baking. The shell 2 is made of steel and has a number of air holes. The lining 1 is nested in the shell 2. Two symmetrical Y-shaped reinforcement plates 3 with exactly the same size and position are welded on the left and right sides of the shell 2. Branch fixing ears 41 are set on the two branches above the Y of each Y-shaped reinforcement plate 3. A bottom fixing ear 42 is set at the bottom of the reinforcement plate. A lifting ear 5 is welded in the middle of the reinforcement plate. The length of the lifting ear 5 is longer than that of the fixed ear. A lifting ring 6 is fixedly set at the middle position of the bottom of the front and rear sides of the shell 2. The two lifting rings 6 are symmetrically set.

[0022] like Figure 2 As shown, it is a structural schematic diagram of a corresponding bracket of a portable ladle for two-sided pouring used in conjunction with the above-mentioned ladle, including a base 13, the base 13 is arranged on a trolley, and a track is arranged at the bottom of the trolley. The trolley can move on the track at the bottom of the trolley, thereby realizing the movement of the position of the ladle, so that the pouring work at different points can be performed by frequent movement on the ground track, instead of frequently using the overhead crane to move in the air, and the safety and precision are significantly improved. Two support frames 10 of the same size and relative positions are fixedly arranged on the left and right sides of the base 13, the bottom of the support frame 10 is welded and fixed to the base 13, and the top of the support frame 10 is hinged with a flip frame 9, one end of the flip frame 9 is hinged to the support frame 10, and the other end is hinged to one end of the telescopic rod 11. The other end of the telescopic rod 11 is fixedly arranged on the base. In this embodiment, the telescopic rod 11 adopts a hydraulic rod, which has a stronger telescopic force and is more convenient to operate.

[0023] Two support side panels 7 of the same size and opposite positions are welded on the inner sides of the two flip frames 9 of the two support frames 10, respectively. The upper edge of the vertically fixed support side panel 7 is wavy, and the wavy shape is provided with wavy grooves respectively matched with the branch fixing ears 41, the lifting ears 5 and the bottom fixing ears 42. The two support side panels 7 can lift the lifting ears 5 and the fixing ears on both sides of the ladle with the help of the wavy grooves, so as to realize the load-bearing and fixation of the ladle. At the same time, in this embodiment, a support front plate 8 and a support bottom plate 12 are also provided between the two relative support side panels 7 to realize better load-bearing and fixation of the ladle. The support front plate 8 is arranged on the front side of the two support side panels 7, and the support front plate 8 is in an arc shape to better adapt to the cylindrical body of the ladle. The support bottom plate 12 is arranged at the bottom of the two support side panels 7 and connected to each other to better cover the bottom and carry the ladle. Both sides of the wavy groove on the edge of the bracket side plate 7 that is adapted to the branch fixing ear and the wavy groove that is adapted to the bottom fixing ear 42 are raised blocking parts, which are used to effectively prevent the ladle from slipping when the telescopic rod is extended to drive the ladle to flip. When the flipping angle of the ladle is >90°, the raised blocking parts on both sides can effectively prevent the ladle from slipping. At the same time, the lifting rings 6 at the bottom of both sides of the ladle shell can also be connected to safety ropes, which are used to cooperate with the raised parts to deal with sudden situations of flipping and slipping.

[0024] Principle and usage: With the help of the portable two-sided pouring ladle and the corresponding bracket of the utility model, it is used for the production of centrifugal ductile iron pipes, and the operation steps are as follows:

[0025] Step 1: Loading, adding ferrosilicon to the ladle, pouring high-temperature molten iron into the ladle by the electric furnace, spraying magnesium for spheroidization, and spectroscopic analysis of the molten iron composition. The ladle lifting lug 5 is hoisted by the overhead crane and enters the bracket from the upper rear. The ladle branch fixing lug 41, the bottom fixing lug 42 and the lifting lug 5 are correspondingly placed in the wavy groove of the bracket side plate 7 to achieve the fixation of the ladle and the corresponding bracket, such as Figure 3 Figure 4 As shown, the overhead travelling crane exits;

[0026] Step 2: Turning the ladle, the remote control ladle support bottom trolley moves on the track, directing the support to move left and right to the ladle turning position, the hydraulic pump is started, the hydraulic rod extends to drive the turning frame 9 and then drives the ladle to turn over and dump the molten metal, then the hydraulic rod retracts to drive the ladle back, and moves left and right to the next ladle turning position, and repeats the above process;

[0027] Step 3: Unloading the ladle. After the molten metal in the ladle is poured out, the ladle lifting lug 5 is lifted by the overhead crane and the bracket is lifted out from the upper rear;

[0028] Step 4: Replace the ladle nozzle. If one side of the ladle nozzle is severely sticky with slag or damaged, affecting the pouring, use an overhead crane to lift the empty ladle and rotate it. Because of the symmetrical design, the other side of the ladle can continue to be used.

[0029] The utility model has simple and safe operations for unloading and turning over the casting ladle, and the casting on both sides prolongs the service life of the casting ladle, can reduce the cost of repairing and baking the casting ladle, and reduces the influence of changing the ladle on the production continuity.

[0030] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
