Description

Technical Field

[0001] The utility model belongs to the technical field of molten iron pouring ladles, in particular to a molten iron pouring ladle. Background Art

[0002] The working principle of the molten iron pouring ladle is to transfer the high-temperature molten iron from the furnace into the pouring ladle, and transport it to the casting mold by a transport vehicle, and then pour the molten iron into the mold through the pouring ladle to obtain the required casting. It is an important equipment for holding and transporting high-temperature molten iron in the casting process, and is used for pouring operations in the foundry workshop.

[0003] In the Chinese utility model patent with patent application number 202020754516.6, a molten iron pouring ladle with an arc-shaped water outlet is proposed. The main problem of this patent is that when the ladle is tilted and rotated, the ladle is lifted by a crane and a lifting frame for operation, which is very easy to shake. Not only will the pouring nozzle collide with the pouring port of the mold, which may easily cause the pouring nozzle and the pouring port to deform and damage over a long period of time, but the shaking of the ladle may also cause the pouring nozzle and the pouring port to be misaligned, and the high-temperature molten iron will be poured outside, causing waste and even accidentally injuring workers.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 3 As shown together, a molten iron pouring ladle includes a ladle body 1 and a hanging frame 2 which are arranged together, a pouring nozzle 3 is provided on the top of the ladle body 1, a rotating frame 4 is rotatably mounted on the ladle body 1, and a direction adjustment mechanism 5 for adjusting the pouring direction of the ladle body 1 is provided between the rotating frame 4 and the ladle body 1.

[0027] In this embodiment, the direction adjustment mechanism 5 is used to adjust the pouring direction of the pouring nozzle 3 on the ladle 1, so that the pouring nozzle 3 can be accurately aligned with the pouring port of the mold, thereby avoiding the high-temperature molten iron from pouring out of the mold due to the misalignment of the pouring nozzle 3 and the pouring port. This not only avoids the waste of high-temperature molten iron, but also avoids the situation where the poured high-temperature molten iron accidentally injures workers, thereby improving the safety of the use of the casting ladle.

[0028] Among them, support stands 6 are respectively arranged on both sides of the package body 1, and the two support stands 6 are symmetrically arranged relative to the pouring nozzle 3. The rotating frame 4 is rotatably installed on the two support stands 6 through the rotating shaft 7. A stabilizing mechanism 8 is commonly arranged between each support stand 6 and the package body 1.

[0029] In this embodiment, the ladle body 1 is fixedly supported and lifted by the support stand 6. Compared with the structure of the traditional molten iron casting ladle which is lifted by a crane and then tilted, the support stand 6 has better support stability for the ladle body 1, thereby solving the problem of the casting ladle shaking due to the tilting of the lifting, and avoiding the problem of the pouring nozzle 3 colliding with the casting port of the mold due to the shaking of the ladle body.

[0030] Moreover, both ends of the lifting frame 2 are rotatably mounted on the rotating shaft 7, a reducer 9 is arranged on the outer side of each supporting frame 6, each rotating shaft 7 is fixedly connected to the output shaft of the reducer 9, and a tilting handwheel 10 is fixedly mounted on the input shaft of each reducer 9.

[0031] In this embodiment, a reducer 9 and a tilting hand wheel 10 are respectively provided on both sides of the ladle body 1, and workers standing on both sides of the casting ladle can adjust the tilting angle.

[0032] In this embodiment, the reducer 9 adopts a worm gear reducer available on the market, and its structure and working principle constitute the prior art and are well known to ordinary technicians in this field, so they will not be described in detail here.

[0033] like Figure 1 and Figure 2 As shown together, each stabilizing mechanism 8 includes a concentrically arranged arc guide groove 81 and an arc guide rod 82, each of which is coaxially arranged with the rotating shaft 7, each of which is penetrated through the corresponding supporting frame 6, each of which is fixedly mounted on the side wall of the corresponding supporting frame 6, and two oppositely arranged stabilizing columns 83 are fixed on the outer wall of the package body 1, and the positions of the two stabilizing columns 83 correspond to the positions of the arc guide groove 81, each of which passes through the corresponding arc guide groove 81, and each of which is slidably mounted with a slider 84, and each of which is fixedly connected to the corresponding stabilizing column 83.

[0034] In this embodiment, the arc-shaped guide grooves 81 and arc-shaped guide rods 82 provided on both sides play a role in guiding the bag body 1 to rotate smoothly, solving the problem of the bag body 1 shaking easily during the tilting and returning process, thereby improving the reliability and stability of the tilting of the bag body 1.

[0035] Among them, each arc guide rod 82 includes a guide portion 821, and each guide portion 821 has a vibration-damping portion 822 at both ends. Each vibration-damping portion 822 is integrally formed with the corresponding guide portion 821, and each vibration-damping portion 822 is sleeved with a reset vibration-damping spring 85, and the position and length of each reset vibration-damping spring 85 are adapted to the movement trajectory of the slider 84.

[0036] In this embodiment, the two reset damping springs 85 are used to dampen the tilting and returning of the package body 1. When the package body 1 tilts, the corresponding reset damping springs 85 can effectively prevent the pouring nozzle 3 from colliding with the pouring port of the mold, thereby preventing the pouring nozzle 3 and the pouring port from being deformed and damaged.

[0037] On the contrary, when the package body 1 rotates back to its original position, another reset damping spring 85 uses its own elastic properties to limit and buffer the package body 1, which not only reduces the shaking of the package body 1, but also prevents the package body 1 from returning to its original position too much, thereby preventing the high-temperature molten iron in the package body 1 from spilling due to shaking or tilting.

[0038] like Figure 1 and Figure 2 As shown together, the two arc-shaped guide grooves 81 are staggered up and down, and the two arc-shaped guide grooves 81 are coaxially arranged, wherein one arc-shaped guide groove 81 and the arc-shaped guide rod 82 are arranged at the upper end of the corresponding support frame 6, and the other arc-shaped guide groove 81 and the arc-shaped guide rod 82 are arranged at the lower end of the corresponding support frame 6.

[0039] In this embodiment, the arc-shaped guide grooves 81 arranged in a staggered manner increase the stability of the rotation of the package body 1 .

[0040] like Figure 1 and Figure 3 As shown together, the direction adjustment mechanism 5 includes a driving gear 51 rotatably mounted on the rotating frame 4, the driving gear 51 is located on the side of the package 1 away from the pouring nozzle 3, an adjusting hand wheel 52 is rotatably mounted on the outer wall of the rotating frame 4, the adjusting hand wheel 52 is fixedly connected to the shaft of the driving gear 51, and a driven gear ring 53 is fixedly mounted on the outer wall of the package 1, and the driven gear ring 53 is meshed with the driving gear 51.

[0041] In addition, the rotating frame 4 includes a first ring seat 41 and a second ring seat 42 arranged up and down. The first ring seat 41 and the second ring seat 42 are both sleeved on the package body 1, and the first ring seat 41 and the second ring seat 42 are both rotatably connected to the outer wall of the package body 1.

[0042] The method of using the utility model is as follows:

[0043] The first step is to use the hook on the crane to hang the hoisting frame 2 to hoist the casting ladle to the position for holding the high-temperature molten iron, and to hold a certain amount of high-temperature molten iron inside the ladle body 1. Then, use the crane to hoist the casting ladle to the position of the mold and place it on one side of the mold. At this time, the two supporting frames 6 are supported on the ground to support and fix the ladle body 1.

[0044] The second step is to rotate the adjustment hand wheel 52, which drives the driving gear 51 to rotate. The rotating driving gear 51 is continuously meshed with the driven gear ring 53, thereby driving the package body 1 to rotate through the driven gear ring 53, and finally the pouring nozzle 3 is completely aligned with the pouring port of the mold.

[0045] The third step is to rotate the tilting hand wheel 10. The tilting hand wheel 10 drives the rotating shaft 7 to rotate through the reducer 9. The rotating shaft 7 drives the ladle 1 to tilt so that the top opening of the ladle 1 rotates downward, and the high-temperature molten iron is poured into the mold through the pouring nozzle 3 to complete the pouring operation.

[0046] The fourth step is to rotate the tilting hand wheel 10 in the opposite direction after the pouring operation is completed, so as to drive the package body 1 to rotate back to its original position, so that the package body 1 is rotated to a vertical state again.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
