DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] This device is mainly used in conjunction with a pneumatic assist arm and can move and lift within a certain range.

[0022] As Figure 1 , Figure 2 and Figure 3 shown, it is a handling jig applicable to ladles and mold shells, including a bearing seat 1, a handle 4, a transparent protective cover 6, and a ladle 9. The ladle 9 can be replaced with a mold shell. The bearing seat 1 is connected with a transmission shaft 3 through a bearing 2. The setting of the bearing 2 enables the transmission shaft 3 to rotate within the bearing seat 1. At the same time, the bearing 2 is provided with a bearing retaining ring 24 for fixing the bearing 2 to prevent its axial movement. One end of the transmission shaft 3 penetrates through the transparent protective cover 6 and is fixedly connected with the handle 4. The transparent protective cover 6 and the transmission shaft 3 are fixedly connected together. The other end is equipped with a handling component for handling the ladle 9. On both sides of the transparent protective cover 6, there are respectively a bushing 5 and a first gasket 7 fixedly connected with the transmission shaft 3. The bushing 5 and the first gasket 7 are inserted with a first indexing pin 25 for restricting the rotation of the transmission shaft 3.

[0023] By inserting and removing the first indexing pin 25, it is possible to control whether the transmission shaft 3 rotates within the bearing seat 1. When it is necessary to pour the molten steel in the ladle 9 into the mold shell, the first indexing pin 25 is pulled out to disengage the bushing 5 and the first gasket 7 from the restriction. At this time, the handle 4 can be rotated to drive the transmission shaft 3 to rotate within the bearing seat 1, and the bearing seat 1 will drive the ladle 9 to rotate through the handling component, pouring the liquid molten steel in the ladle 9 into the mold shell.

[0024] As Figure 2 shown, the handling component includes a fork crossbar 8. The fork crossbar 8 is fixedly connected with the end of the transmission shaft 3 away from the handle 4, and both ends of the fork crossbar 8 are connected with round bars 17 through fixing components. The two round bars 17 are respectively inserted into the two lifting lugs of the ladle 9.

[0025] The two round bars 17 and a fork crossbar 8 form a "U" shape. At the same time, the two round bars 17 can adjust their installation positions on the fork crossbar 8 through the fixing components, so as to adapt to ladles 9 of different specifications and sizes.

[0026] As Figure 1 and Figure 2 shown, the fixing component includes a second square tube fixing clip 27. On both sides of the second square tube fixing clip 27, there are respectively fixedly connected a first square tube fixing clip 15 and a guide shaft support 16. The second square tube fixing clip 27 and the first square tube fixing clip 15 can be disassembled and separated. The fork crossbar 8 is fixed between the first square tube fixing clip 15 and the second square tube fixing clip 27. One end of the round bar 17 is fixedly connected with the guide shaft support 16.

[0027] When the size of the ladle 9 changes, the first square tube fixing clamp 15 can be separated from the second square tube fixing clamp 27, and the positions of the two round rods 17 installed on the fork cross bar 8 can be adjusted until the two round rods 17 can be reinserted into the two lifting ears of the ladle 9.

[0028] like Figure 3 As shown, one side of the bearing seat 1 is connected to a first steel frame via a transition assembly, and the first steel frame is connected to the pneumatic booster arm via a first flange 10 .

[0029] The pneumatic booster arm is connected with the clamp to facilitate the operator to carry the ladle 9, so that the operator can operate it without paying a lot of physical labor.

[0030] like Figure 3 As shown, the adapter assembly includes a pin shaft 14, the outer ring of the pin shaft 14 is rotatably connected to the second steel frame and the third steel frame, the second steel frame is connected to the bearing seat 1 through the second flange 12, the third steel frame is connected to the first steel frame through the third flange 13, and the third steel frame is fixedly connected to the second gasket 28, the inner ring of the second gasket 28 is movably sleeved with a second indexing pin 26, and the second indexing pin 26 is plugged into the second steel frame.

[0031] The second indexing pin 26 is used to limit the angle deviation of the second steel frame and the third steel frame. When the ladle 9 is transported into the furnace, multiple layers can be stacked in the furnace. The ladle 9 that is not affected by the size of the furnace door can be transported horizontally into the furnace. When the ladle 9 affected by the size of the furnace door cannot be placed horizontally in the furnace, the second indexing pin 26 is pulled out to completely separate it from the second steel frame. At this time, the handle 4 is pressed down by a maximum of 45° to make the ladle 9 tilt around the pin shaft 14 as the axis and placed obliquely into the furnace.

[0032] like Figure 3 As shown, the sides of the bearing seat 1 and the shaft sleeve 5 that are close to each other are fixedly connected with limit blocks 11, and the two limit blocks 11 cooperate with each other to limit the rotation range of the transmission shaft 3.

[0033] The limit of the limit block 11 prevents the ladle 9 from tipping over due to its own gravity when it is turned over, thus avoiding production accidents.

[0034] like Figure 1 and Figure 2 As shown, the handle 4 is fixedly mounted with a button box cover 29, and the button box cover 29 is mounted with an emergency stop switch 19, a flat head switch 20, a load indicator 21, a brake valve 22 and an up and down lift valve 23 for controlling the pneumatic power-assisting arm.

[0035] Working principle: In the first step, the clamp goes to the molten steel firing furnace to receive the liquid steel. After it is full of molten steel, it is moved to the mold shell placement station, the first indexing pin 25 is pulled open, and the handle 4 is manually rotated (maximum range 120°) to pour the liquid steel in the ladle 9 into the mold shell. After the mold shell is full, the handle 4 is manually rotated to reset, and the first indexing pin 25 is reset to lock the handle 4. All subsequent actions of receiving molten steel to the mold shell are to repeat the above actions.

[0036] The second step is to send the mold shell filled with molten steel into the furnace. After the clamp grabs the mold shell (there are double ears with holes on both sides of the mold shell, and the two round rods 17 in the clamp extend into the double ears with holes in the mold shell, and the distance between the round rods 17 on both sides of the clamp can be adjusted), the clamp transports the mold shell into the furnace. When the ladle 9 is not affected by the size of the furnace door, it can be horizontally transported into the furnace. When the ladle 9 affected by the size of the furnace door cannot be placed horizontally in the furnace, the second indexing pin 26 is pulled out to completely separate it from the second steel frame. At this time, by pressing down the handle 4 (maximum amplitude 45°), the ladle 9 is tilted with the pin shaft 14 as the axis and placed obliquely into the furnace. Manually, only the handle 4 needs to be slightly pressed downward in the appropriate position to place the mold shell in the furnace, and the clamp is manually pulled out of the mold shell. Outside the furnace, there is no need to manually press the handle 4, and the clamp automatically balances.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
