Description

Technical Field

[0001] The utility model relates to the technical field of crucible transportation, in particular to a crucible transportation device. Background Art

[0002] There are many types and specifications of crucibles. When used, they are not limited by production scale, batch size and type of smelting materials. They can be selected arbitrarily, have strong applicability, and can ensure the purity of the smelted materials. Place in a dry place after use to avoid rainwater intrusion; before use, it must be slowly baked to 500 degrees Celsius. Add materials according to the capacity of the crucible, and avoid squeezing too tightly to prevent the metal from thermal expansion and cracking the crucible. When taking out the molten metal, it is best to scoop it out with a spoon and use calipers as little as possible. If calipers and other tools are used, they should be consistent with the shape of the crucible to avoid excessive local force and shorten the service life. The service life of the crucible is related to its usage. Strong oxidizing flames should be avoided from being directly sprayed onto the crucible, which will cause the raw materials of the crucible to oxidize and shorten their life. The raw materials for the production of crucibles can be summarized into three types. One is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker. Since 2008, we have started to use high temperature resistant synthetic materials such as silicon carbide, alumina and ferrosilicon as the framework clinker of crucibles. This clinker has a significant effect on improving the quality of crucible products and enhancing the density and mechanical strength of crucibles.

A bearing seat 13 is movably sleeved on one end of the two-way lead screw 12 away from the forward and reverse motor 10. Slide bars 11 are fixedly installed at the front and rear ends of the left and right side walls of the inner arm body 1 near the top. A connecting end 6 is fixedly installed at the center of the top of the arm body 1, and a connecting hook 7 is arranged on the connecting end 6. A control box 8 is fixedly installed at the top of the arm body 1 near the right side.

[0023] Specifically, one end of the bearing seat 13 away from the bidirectional screw rod 12 is fixedly connected to a position near the top of the center of the inner right side wall of the clamp arm body 1 .

[0024] In this embodiment, the stability of the bidirectional screw rod 12 during rotation is enhanced.

[0025] Specifically, the two sliders 2 near the front and rear ends are movably sleeved with the outer surfaces of the two slide bars 11 respectively.

[0026] In this embodiment, it is convenient for the subsequent slider 2 to move along the slide rod 11 .

[0027] Specifically, one end of the bidirectional screw rod 12 away from the bearing seat 13 passes through the inner left wall of the clamp arm body 1, the mounting plate 4 and the motor box 5 and is connected to the forward and reverse motor 10. The connection between the bidirectional screw rod 12 and the clamp arm body 1, the mounting plate 4 and the motor box 5 is a movable socket.

[0028] In this embodiment, it is convenient for the subsequent forward and reverse motor 10 to drive the bidirectional screw rod 12 to rotate.

[0029] Specifically, the left and right sides of the two spring sheets 18 are fixedly connected to the left and right side walls inside the two installation slots 17 respectively.

[0030] In this embodiment, the stability of the spring piece 18 is enhanced.

[0031] Specifically, the interiors of the two springs 16 are movably sleeved with the outer surfaces of the two pressure sensors 15 .

[0032] In this embodiment, the spring 16 is used to enhance the elasticity of the spring 18 and also protect the pressure sensor 15 .

[0033] Specifically, the two movable blocks 19 are movably sleeved with adjacent sides of the two sliding blocks 2 respectively.

[0034] In this embodiment, the movable block 19 is convenient to move forward and backward.

[0035] Specifically, adjacent sides of the two anti-slip plates 3 are both provided with anti-slip grooves.

[0036] In this embodiment, the anti-slip effect of the anti-slip plate 3 is enhanced.

[0037] When in use, the clamp arm body 1 is placed on the top of the crucible and the two anti-skid plates 3 are close to the outer surface of the crucible, the forward and reverse motors 10 are started, and the bidirectional screw rod 12 is driven to rotate by the forward and reverse motors 10, so that the two sliders 2 are driven to gather toward the center along the slide rod 11 by utilizing the characteristics of the bidirectional screw rod 12. After the anti-skid plate 3 contacts the crucible, the distance between the two sliders 2 and the crucible is gradually reduced, and the anti-skid plate 3 retracts due to the extrusion force. When the anti-skid plate 3 retracts, the sliders 2 and the limiter are driven to move toward the inside of the installation groove 17, so that the connecting block 20 bends the center of the spring piece 18 when moving toward the inside of the installation groove 17, and the spring 16 contracts due to the bending of the spring piece 18, so that the end of the spring piece 18 away from the connecting block 20 contacts the contact end of the pressure sensor 15, and when the pressure sensor 15 senses the pressure, the forward and reverse motors 10 are electrically turned off, so that the two sliders 2 stop moving, and the pressure sensor 15 The fact that the sensor 15 senses that the pressure does not disappear also proves that the crucible is clamped and fixed, which is convenient for carrying the crucible. If a certain gap is generated between the anti-slip plate 3 and the crucible, the pressure disappears, and the spring 16 and the spring piece 18 both push the connecting plate 14, the limit plate 21, the movable block 19 and the anti-slip plate 3 to move toward the direction of the crucible. The pressure sensor 15 cannot sense the pressure or continues to sense the pressure, and then the forward and reverse motor 10 is electrically driven to make the pressure sensor 15 sense the pressure again, thereby playing a safety role and reducing damage to the crucible during transportation. After the crucible is transported, the forward and reverse motor 10 is driven again to make the two sliders 2 move away from the crucible respectively, and the pressure on the spring 16 and the spring piece 18 disappears. The elastic force generated by compression makes the connecting plate 14, the limit plate 21, the movable block 19 and the anti-slip plate 3 return to their original positions, and the crucible is also separated from the clamping of the anti-slip plate 3 and the two sliders 2, which is also convenient for carrying the next crucible.

[0038] To sum up, the crucible transfer device, by providing the spring 16 and the spring 18, can ensure that the pressure sensor 15 can accurately sense after the pressure disappears, and also helps to protect the pressure sensor 15 from excessive impact and vibration and does not cause damage. By providing the pressure sensor 15, the anti-slip plate 3, the forward and reverse motor 10, the bidirectional screw rod 12, the slide rod 11 and the slide block 2, the crucible can be conveniently clamped and fixed, and the crucible can be prevented from falling during transportation, thereby improving production efficiency and reducing the damage rate of the crucible.
