Description

Technical Field

[0001] The invention relates to the technical field of casting, in particular to a labor-saving weighable casting trolley which can move up and down, forward and backward, left and right. Background Art

[0002] A smelting furnace refers to a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then melts them into the required alloy through operations such as slagging and refining. During casting, steel needs to be melted into molten steel, which is then transported to a centrifugal casting machine through a ladle. The liquid metal is poured into a rotating mold, which is filled and solidified into a casting under the action of centrifugal force.

[0003] However, when the smelting furnace transports the molten steel to the ladle, the ladle needs to be placed near the smelting furnace. The smelting furnace pours the molten steel into the ladle, and then pours it from the ladle into the centrifugal casting machine. Due to the change in the amount of molten steel in the smelting furnace, the height of the ladle is different, and the centrifugal casting machine also has a certain height. The staff is required to tilt the centrifugal casting machine to pour, which is inconvenient for the staff to operate. At the same time, the amount poured into the ladle needs to be weighed, which increases the labor intensity of the staff, so improvements are needed. Summary of the invention

A fixed plate 16 is slidably connected between the two support rods 17. A connecting rod 18 is fixed to one side of the lower end of the fixed plate 16. The lower ends of the two support rods 17 are slidably connected to a connecting plate 20. The connecting plate 20 and the connecting rod 18 can move left and right, thereby driving the ladle 22 to move. According to the position of pouring molten steel and pouring molten steel into the centrifugal casting machine as needed, the ladle 22 is adjusted left and right to ensure that the molten steel is accurately poured into the ladle or into the centrifugal casting machine. A limiting opening 27 is provided on the two connecting plates 20. The limiting opening 27 limits the limiting rod 1 and facilitates the movement of the ladle 22;

[0024] Reference Figure 1-4 A lifting device is provided between the support plate 5 and the scale 7. Two first rollers 2 are installed on both sides of the lower end of the U-shaped frame 3. The first rollers 2 are convenient for sliding on the guide rails 4 to adjust the distance between the ladle and the smelting furnace and the centrifugal casting machine to prevent the molten steel from spilling when pouring the molten steel, causing waste. The two first rollers 2 are respectively located on the two guide rails 4. Rotating rods 21 are rotatably sleeved at both ends of the U-shaped frame 3. A ladle 22 is commonly fixed between the two rotating rods 21. The rotation of the rotating rod 21 will drive the rotation of the ladle 22, thereby facilitating the adjustment of the inclination angle of the ladle 22 and pouring the molten steel into the centrifugal casting machine. One end of the two rotating rods 21 passes through the limiting opening 27 and extends to one side of the connecting plate 20. A limiting device is provided on the connecting plate 20. The limiting device limits the rotating rod 21 to prevent the ladle from rotating when adding molten steel to the ladle 22 or when the ladle 22 moves, resulting in leakage of molten steel.

[0025] Reference Figure 1 and 4The lifting device includes a first push rod 6 rotatably connected to both sides of the lower end of the support plate 5, the lower ends of the two first push rods 6 are connected to second rollers 8, and the two second rollers 8 are in contact with the scale 7, and the two second rollers 8 can slide left and right on the scale 7, and a fixed rod 28 is rotatably connected between the two first push rods 6, and the movement of the fixed rod 28 will cause the two first push rods 6 to move, and the upper end of the scale 7 is rotatably connected to two second push rods 11 on both sides, and one end of the two second push rods 11 is connected to a third roller 10, and the movement of the third roller 10 will change the angle of the two second push rods 11, and the two third rollers 10 are in contact with the support plate 5. At the lower end, two second push rods 11 are rotatably connected with another first fixed rod 28, two mounting rods 9 are installed on one of the fixed rods 28, and a handle 29 is fixed between the two mounting rods 9. The handle 29 pushes the movement of the two mounting rods 9, thereby pushing the fixed rod 28 to move. A first push rod 6 and a second push rod 11 on the same side form a group, and the first push rod 6 and the second push rod 11 of the same group are rotatably connected with each other. The movement of the fixed rod 28 will cause the two first push rods 6 to rotate, and the height of the support plate 5 is adjusted, thereby adjusting the height of the ladle, so as to facilitate the reception of molten steel in the smelting furnace and adjust according to the amount of molten steel in the smelting furnace.

[0026] Reference Figure 2 and 3 The limiting device includes a rotating plate 25 fixed at one end of the rotating rod 21, and a positioning pin 24 is rotatably connected to the rotating plate 25. The limiting rods 1 are fixed at both ends of the U-shaped frame 3, and the limiting rods 1 are slidably connected in the limiting opening 27. The limiting rod 1 is provided with a socket 26, and the socket 26 and the positioning pin 24 are correspondingly arranged.

[0027] Reference Figure 2 A connecting rod 18 is fixed to one side of the lower end of the fixed plate 16, and a telescopic rod 19 is fixed to one side of the lower end of the connecting rod 18. The movement of the fixed plate 16 will drive the connecting rod 18 to move. A pull rod 23 is fixed to one end of the U-shaped frame 3, and the lower end of the telescopic rod 19 is fixed to the lower end of the pull rod 23. The telescopic rod 19 is convenient for controlling the movement of the pull rod 23, and the U-shaped frame 3 can move stably when moving.

[0028] In the present invention, when in use, four bearing rods 14 are placed beside the centrifugal casting machine, and the ladle 22 is set at the lower end of the smelting furnace. When molten steel is brought into the ladle 22, the handle 29 is moved, and the handle 29 moves the mounting rod 9 and the fixing rod 28, and the fixing rod 28 moves the two second rollers 8, and the second rollers 8 rotate the two first push rods 6, and when the first push rods 6 rotate, they drive the two third rollers 10 to move, thereby moving the two second push rods 11, so as to prop up the support plate 5, and after the ladle 22 is pushed to a suitable distance in the smelting furnace, the smelting furnace pours molten steel into the ladle 22, and at that time, it is necessary to watch the changes in the numbers on the scale 7, and stop pouring after the added weight is appropriate, and then push Move the pull rod 23, which drives the U-shaped frame 3 to move. Due to the cooperation between the support rod 17, the connecting plate 20 and the limit rod 1, the ladle 22 will move together and move to the upper end of the centrifugal casting machine. At this time, the positioning pin 24 is pulled out, and the rotating rod 21 is rotated. The rotating rod 21 drives the ladle 22 to rotate, and the ladle 22 is poured into the centrifugal casting machine. When the centrifugal casting machine or the smelting furnace is located at a higher position or it is inconvenient to pour molten steel, the pull rod 23 can be pushed upward, and the pull rod 23 drives the U-shaped frame 3 to move on the limit opening 27 and rise to a suitable position. Then the positioning pin 24 is pulled out, and the rotating rod 21 is rotated to pour the molten steel. The whole process is convenient and fast, and at the same time, it is ensured that the amount of molten steel added meets the requirements, and workers do not need to judge again.
