Abstract
Description
Technical Field
[0001] The utility model relates to a casting workpiece of an automobile component, in particular to a casting structure of an automobile main reduction shell, and belongs to the technical field of component casting. Background Art
[0002] During the casting construction of the main reduction shell of an automobile, a crucible and an overhead crane are used to cast the automobile mold. The staff moves the crucible to the molten steel outlet through the overhead crane and the hoist. After the crucible is filled with molten steel, the crucible is moved to the side of the mold by the overhead crane and the mold is cast. During the crucible transportation process, the crucible is in an empty state. If the hoist becomes loose, there is a safety hazard that the crucible may fall. Moreover, the existing crucible is fixedly connected to the pillars on both sides. During casting, the crucible and the pillars need to be tilted at the same time, which will affect the staff's observation of the casting condition of the mold and cause the molten steel in the mold to overflow.

DETAILED DESCRIPTION
[0020] The present invention will be further explained and illustrated below with reference to the accompanying drawings:
[0021] For example, see Figure 1-Figure 3 A casting structure of a main reduction shell of an automobile includes a fixing ring 1, a first pillar 3, a cross arm 5 and a second pillar 6. The first connecting blocks 2 are rotatably connected at both ends of the fixing ring 1. The first pillar 3 is provided on the first connecting block 2 located on the left side of the fixing ring 1. The cross arm 5 is sleeved on the first pillar 3. The second pillar 6 is provided at the bottom of the right end of the cross arm 5. The second pillar 6 is inserted into the first connecting block 2 on the right side of the fixing ring 1 and fixed by bolts; a slot 15 is provided on the fixing ring 1 below the first connecting block 2, and a handle 16 is connected to the slot 15 by bolts. A third connecting block 9 is provided on the outer wall of the fixing ring 1, and a hook column 11 is inserted in the third connecting block 9. The bottom of the hook column 11 is connected to a base 12. Three support handles 13 are evenly provided on the outer wall of the base 12, and a roller 14 is provided at the bottom of the support handle 13.
[0022] A first limiting block 4 is provided on the top of the first pillar 3 .
[0023] A lifting lug 7 is provided on the top of the cross arm 5 , and a through hole 601 is dug at the bottom of the second support column 6 .
[0024] The hook column 11 is connected to the third connecting block 9 by bolts. The third connecting block 9 is arranged in the middle of the outer wall of the fixing ring 1 and is located between the two first connecting blocks 2. The hook column 11 is distributed in an L shape.
[0025] Four second connection blocks 8 are evenly arranged on the outer wall of the fixing ring 1 . A limiting hook 10 runs through the second connection block 8 . The limiting hook 10 is fixedly connected to the second connection block 8 by bolts.
[0026] A groove is dug at the top of the first connecting block 2 on the right side of the fixing ring 1 , and the position of the second support 6 corresponds to the position of the groove above and below.
[0027] In the above description, when the crucible needs to be placed in the fixed ring, move the cross arm to pull the second pillar out of the second connecting block on the right, and rotate the cross arm or the second pillar to place the crucible in the fixed ring. After placement, rotate the cross arm or the second pillar and insert the second pillar into the second connecting block on the right, and then fix the interface with bolts.
[0028] In the above description, the bolts on the outside of the second connecting block sequentially penetrate the second connecting block and the through holes at the bottom of the second pillar to fix the second pillar.
[0029] In the above description, the limiting hooks are distributed in an L-shape, which plays a role in fixing the crucible to avoid the safety hazard of the crucible sliding when the crucible is tipped over.
[0030] In the above description, when in use, the position of the hook column can be adjusted so that the bottom of the crucible fits on the base.
[0031] In the above description, a lifting lug is provided on the top of the cross arm, and the lifting lug is located in the middle of the cross arm.
[0032] During construction, adjust the position of the hook column and place the crucible in the fixed ring. Fix the four sides of the crucible with the limit hook, then place the handle in the slot and fix it with bolts. Move the crucible to the overhead crane with the handle and fix the lifting lug with the lifting device under the overhead crane. Use the overhead crane to move the crucible to the molten steel outlet. When the crucible is filled with molten steel, use the overhead crane or roller to move the crucible. When casting, the overhead crane is required to lift the crossbar of the crucible and use the handle to tilt it for casting.
[0033] The utility model makes the support and the fixed ring become a movable connection, which is helpful for workers to observe the pouring situation of the mold during casting; by arranging rollers at the support handle of the base, the crucible can be placed on the ground for horizontal movement, ensuring the stability and safety of the crucible transportation, and is easy to use, simple to operate, and easy to promote.
