Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite crucible processing technology, and specifically discloses a material handling device for graphite crucible processing. Background Technology
[0002] Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, they have a small coefficient of thermal expansion and a certain resistance to strain from rapid heating and cooling. They are widely used in the smelting of alloy tool steel and the melting of non-ferrous metals and their alloys. During the production process, graphite crucibles need to be shaped using molds. After the graphite crucible is formed, the mold is removed, and then the crucible is taken out from the processing area and transported to the finished product storage area.
[0003] Existing technology typically involves operators using clamps to remove graphite crucibles from the mold. However, since the clamps require deliberate, continuous manual pressure from the operator to achieve a clamping effect, during transportation, operational errors or insufficient pressure can easily reduce the friction between the clamps and the graphite crucible, causing the crucible to detach from the clamps and resulting in material loss. Therefore, a material handling device for graphite crucible processing is needed to solve this problem. Utility Model Content
[0004] This utility model proposes a material handling device for processing graphite crucibles. Through a gravity-driven self-locking internal support structure and a high-temperature resistant and anti-slip design, it realizes automatic clamping, stable gripping, and non-destructive handling of graphite crucibles.
[0005] This utility model is implemented as follows: a material handling device for processing graphite crucibles includes a sleeve, a sliding rod slidably connected to the inner wall of the sleeve, two sets of circumferentially distributed first connecting rods hinged to the lower end of the outer wall of the sliding rod via a hinge seat, multiple circumferentially distributed second connecting rods hinged to the outer wall of the sleeve via a hinge seat, and multiple circumferentially distributed inner support plates provided outside the sliding rod, with the other ends of the first and second connecting rods located on the same side both hinged to the inner wall of the inner support plate via a hinge seat;
[0006] The outer wall of the sleeve is fixedly connected to a first conical platform, and a conical groove is formed on the lower end face of the first conical platform. The outer wall of the sleeve is slidably connected to a second conical platform that is opposite to the first conical platform. The upper end face of the second conical platform is fixedly connected to a third conical platform that matches the conical groove. The outer wall of the slide rod is hinged to a plurality of circumferentially distributed grippers through a hinge seat. The lower ends of the plurality of grippers are all fixedly connected to hooks that engage with the conical grooves.
[0007] As a preferred embodiment of the material handling device for processing graphite crucibles according to this utility model, the outer wall of the sleeve is fixedly connected with a plurality of circumferentially distributed limiting rods.
[0008] As a preferred embodiment of the material handling device for processing graphite crucibles according to this utility model, the inner support plate is arc-shaped.
[0009] As a preferred embodiment of the material handling device for processing graphite crucibles according to this utility model, the lower end of the gripper is provided with a rounded corner.
[0010] As a preferred embodiment of the material handling device for processing graphite crucibles according to this utility model, a handle is fixedly connected to the upper end of the slide rod.
[0011] As a preferred embodiment of the material handling device for graphite crucible processing according to this utility model, the outer wall of the inner support plate is provided with a high-temperature resistant rubber pad, and the outer wall of the high-temperature resistant rubber pad is provided with anti-slip texture.
[0012] The beneficial effects of this utility model are:
[0013] 1. When the sliding rod is pulled upward, the inner support plate expands outward by the gravity of the device itself, achieving a self-locking clamping. It can be stably gripped without additional force. After transfer, the crucible can be easily released by simply pushing the sliding rod down. The operation is simple and labor-saving.
[0014] 2. The outer wall of the inner support plate is equipped with a high-temperature resistant rubber pad and anti-slip texture, which not only enhances friction to prevent slipping, but also avoids direct contact between hard parts and the inner wall of the crucible, effectively protecting the surface of the graphite crucible from damage. It is suitable for high-temperature working conditions. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0021] Please see Figure 1-3 A material handling device for processing graphite crucibles includes a sleeve 1. A slide rod 2 is slidably connected to the inner wall of the sleeve 1. Two sets of circumferentially distributed first connecting rods 4 are hinged to the lower end of the outer wall of the slide rod 2 through a hinge seat. Multiple circumferentially distributed second connecting rods 5 are hinged to the outer wall of the sleeve 1 through a hinge seat. Multiple circumferentially distributed inner support plates 3 are provided on the outside of the slide rod 2. The other ends of the first connecting rods 4 and the second connecting rods 5 located on the same side are both hinged to the inner wall of the inner support plate 3 through a hinge seat.
[0022] A first conical platform 6 is fixedly connected to the outer wall of the sleeve 1. A conical groove 7 is provided on the lower end face of the first conical platform 6. A second conical platform 8 is slidably connected to the outer wall of the sleeve 1, which is arranged in the opposite direction to the first conical platform 6. A third conical platform 9 that matches the conical groove 7 is fixedly connected to the upper end face of the second conical platform 8. A plurality of circumferentially distributed grippers 10 are hinged to the outer wall of the slide rod 2 through a hinge seat. The lower ends of the plurality of grippers 10 are all fixedly connected to hooks 11 that are inserted into the conical groove 7.
[0023] In this embodiment: By inserting the handle into the crucible, the limiting rod 12 rests on the upper edge of the crucible (at this time, there is a gap between the bottom end of the slide rod 2 and the bottom of the crucible). The slide rod 2 is then pushed further into the crucible, causing multiple grippers 10 to move downwards to below the second conical platform 8. Under their own weight, the grippers 10 hold the second conical platform 8, pulling the slide rod 2 upwards. This causes the second conical platform 8 to slide upwards along the slide rod 2, making the first conical platform 6 and the second conical platform 8 fit together (the third conical platform 9 is engaged in the conical shape). If the crucible is in groove 7, pulling the slide rod 2 upwards will cause the gripper 10 to disengage from the first conical platform 6 and move above the first conical platform 6. At this time, the slide rod 2 and the sleeve 1 lose their limiting position. Pulling the slide rod 2 upwards will cause multiple inner support plates 3 to move outwards synchronously through the first connecting rod 4 and the second connecting rod 5, supporting and lifting the crucible from the inside. After the crucible is transferred to the designated location, pushing the slide rod 2 downwards will cause the slide rod 2 to move inwards synchronously through the first connecting rod 4 and the second connecting rod 5, and the gripper 10 will re-engage in the conical groove 7, thus releasing the crucible. When the slide rod 2 is pulled upwards, the inner support plates 3 are expanded outwards by the device's own gravity to fix the crucible from the inside, without requiring continuous force from the operator, resulting in good performance.
[0024] As a technical optimization of this utility model, the outer wall of the sleeve 1 is fixedly connected with a plurality of circumferentially distributed limiting rods 12.
[0025] In this embodiment, the limiting rod 12 facilitates the limitation of the depth of the device extending into the crucible.
[0026] As a technical optimization of this utility model, the inner support plate 3 is arc-shaped.
[0027] In this embodiment, the inner support plate 3 is set to be arc-shaped to better fit the inner wall of the crucible.
[0028] As a technical optimization of this utility model, the lower end of the gripper 10 is provided with a rounded corner.
[0029] In this embodiment, by providing a rounded corner at the lower end of the gripper 10, it is easier for the gripper 10 to move to the area below the second conical platform 8.
[0030] As a technical optimization of this utility model, a handle is fixedly connected to the upper end of the slide bar 2.
[0031] In this embodiment: a handle is fixedly connected to the upper end of the slide bar 2 to facilitate the operator to lift the device.
[0032] As a technical optimization of this utility model, the outer wall of the inner support plate 3 is provided with a high-temperature resistant rubber pad, and the outer wall of the high-temperature resistant rubber pad is provided with anti-slip texture.
[0033] In this embodiment, a high-temperature resistant rubber pad is provided on the outer wall of the inner support plate 3 to improve the friction and anti-slip properties with the inner wall of the graphite crucible, while adapting to the high-temperature environment and avoiding scratching the crucible.
[0034] The working principle and usage process of this utility model are as follows: During use, the handle is inserted into the crucible, allowing the limiting rod 12 to rest on the upper edge of the crucible. The sliding rod 2 is then pushed further into the crucible, causing multiple grippers 10 to move downwards to below the second conical platform 8. Under their own weight, the grippers 10 hold the second conical platform 8, pulling the sliding rod 2 upwards. This causes the second conical platform 8 to slide upwards along the sliding rod 2, bringing the first conical platform 6 and the second conical platform 8 into contact. The process continues... Pulling up the slide rod 2 causes the gripper 10 to disengage from the first conical platform 6 and move above it. At this point, the slide rod 2 loses its limiting position with the sleeve 1. Pulling up the slide rod 2 can cause multiple inner support plates 3 to move outward synchronously via the first connecting rod 4 and the second connecting rod 5, supporting and lifting the crucible from the inside. After the crucible is transferred to the designated location, pushing down the slide rod 2 causes it to move inward synchronously via the first connecting rod 4 and the second connecting rod 5, allowing the gripper 10 to re-engage in the conical groove 7, thus releasing the crucible. This invention utilizes the device's own gravity to drive the inner support plates 3 to expand outward when the slide rod 2 is pulled upward, securing the crucible from the inside without requiring continuous force from the operator, resulting in good performance.

Therefore, they should not be construed as limitations on this utility model.
[0036] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
