Description

TECHNICAL FIELD

[0044] Specifically, the positioning assembly further comprises the compression cavity 25 and the special-shaped clamping block 26. The special-shaped clamping block 26 is arranged in the middle of the shaft sleeve 18. The compression cavity 25 is movably arranged on the inner wall of the special-shaped clamping block 26.

[0045] In the embodiment, the compression cavity 25 is arranged to cooperate with the special-shaped clamping block 26 to control the length of the compression cavity 25 according to the change of the internal pressure, so as to control the angle of the flip cover shaft 19.

[0046] Specifically, one end of the compression cavity 25 is provided with an extension part, the size of the extension part is matched with the size of the flip cover shaft 19. One end of the flip cover shaft 19 is provided with a clamping groove. The other end of the compression cavity 25 is provided with a sealing plug which is tightly combined with the inner wall of the compression cavity 25.

[0047] In the embodiment, the compression cavity 25 forms a closed environment with the special-shaped clamping block 26 under the action of the sealing plug. When the compression cavity 25 moves along the inner wall of the special-shaped clamping block 26 under the extrusion of the flip cover shaft 19, the pressure in the special-shaped clamping block 26 increases, the bottom end of the compression cavity 25 is tightly combined with the outer side of the flip cover shaft 19, and the electromagnetic valve 24 is in a closed state, so that the flip cover shaft 19 cannot be reversed, and the aluminum liquid cover plate 7 can be smoothly flipped.

[0048] Specifically, the protection assembly comprises a micro electric push rod 27 and a telescopic block 28, the micro electric push rod 27 is arranged outside the limiting cylinder 12, and the telescopic block 28 is fixedly installed at one end of the micro electric push rod 27.

[0049] In the embodiment, the micro electric push rod 27 is arranged to drive the telescopic block 28 to move along the inner side of the limiting cylinder 12 to achieve clamping and protection of the rotating shaft 11.

[0050] Specifically, the protection assembly further comprises a hinged clamping column 29, the hinged clamping column 29 is arranged on the inner side wall of the limiting cylinder 12, a mounting groove is arranged in the middle of the limiting cylinder 12, the hinged clamping column 29 is movably connected with the mounting groove through a pin shaft, and the top end of the hinged clamping column 29 is movably connected with the telescopic block 28.

[0051] In the embodiment, the hinged clamping column 29 is arranged to cooperate with the rotating shaft 11 to achieve positioning of the rotating shaft 11, the outer side of the hinged clamping column 29 is provided with a stop lever, when the telescopic block 28 drives the connecting rod to move downward, the curved lever in the hinged clamping column 29 is driven to move downward to be attached to the rotating shaft 11 to achieve positioning.

[0052] Specifically, the outer side of the rotating shaft 11 is provided with a special-shaped clamping groove 30, the number of the special-shaped clamping grooves 30 is several groups and is distributed at equal intervals in a circle, and the protection assembly is located outside the rotating shaft 11.

[0053] In the embodiment, the several groups of special-shaped clamping grooves 30 are arranged to cooperate with the hinged clamping column 29 to achieve buckling to ensure stable operation of the rotating shaft 11 and prevent the tilting frame 4 from being inverted.

[0054] When the molten aluminum in the furnace 6 needs to be poured, the hydraulic jack 31 is first pressed to drive the furnace 6 to move upward, so that the hinge buckle 8 is buckled with the claw 9, ensuring the stability of the furnace 6. Then the hydraulic push rod 10 is pressed to make the hydraulic push rod 10 in the elongated state. With the pushing of the hydraulic push rod 10, one end of the hydraulic push rod 10 pushes the tipping frame 4 to rotate counterclockwise along the inside of the support 3. The rotating shaft 11 is fixedly connected with the tipping frame 4, so that the rotating shaft 11 also rotates counterclockwise. When the rotating shaft 11 rotates, the hinge clamping column 29 is in a separated state from the rotating shaft 11. When the tipping frame 4 is tilted by an angle under the pushing of the hydraulic push rod 10, the micro electric push rod 27 is energized to drive the extension block 28 to move inward. The stop rod outside the hinge clamping column 29 moves downward under the driving of the extension block 28, which drives the curved rod in the hinge clamping column 29 to move downward and abut with the rotating shaft 11 to realize positioning, thereby positioning the rotating shaft 11 to prevent the tipping frame 4 from being reversed due to uneven force. Before the molten aluminum in the furnace 6 is poured, the hydraulic rod 21 is pressed to drive the cover connecting piece 22 and the aluminum cover 7 to move upward. Since the aluminum cover 7 is movably connected with the deflection seat 15 through the special-shaped connecting block 17, the aluminum cover 7 rotates clockwise along the inner wall of the deflection seat 15. The shaft sleeve 18 is used in cooperation with the flip shaft 19 to control the deflection angle of the special-shaped connecting block 17. The exhaust hole 23 is used to discharge the air in the shaft sleeve 18. The electromagnetic valve 24 is used to control the closing state of the exhaust hole 23. The electromagnetic valve 24 is connected with a power supply. When the electromagnetic valve 24 is in a closed state, the compression cavity 25 forms a sealed environment with the special-shaped clamping block 26 under the action of the sealing plug. When the compression cavity 25 is extruded along the inner wall of the special-shaped clamping block 26 under the extrusion of the profile of the flip shaft 19, the pressure in the special-shaped clamping block 26 gradually increases. When the compression cavity 25 moves outward to the maximum position, the bottom end of the compression cavity 25 is tightly buckled with the outside of the flip shaft 19 under the action of air pressure, so that the flip shaft 19 cannot be reversed, ensuring the stable rotation of the aluminum cover 7. When the electromagnetic valve 24 is in an open state, the air in the special-shaped clamping block 26 is discharged. When the flip shaft 19 is extruded to the maximum position of the compression cavity 25, the electromagnetic valve 24 is energized to be in a closed state. The compression cavity 25 is abutted with the inner wall of the special-shaped clamping block 26 under the action of negative pressure, so that the deflection positioning of the flip shaft 19 is released. The hydraulic rod 21 is retracted to realize the back cover of the aluminum cover 7 and the furnace 6, preventing the aluminum from leaking out.
