Description

Technical Field

[0001] The utility model relates to the technical field of crucible hoisting clamps, and more specifically, to a graphite crucible unloading hoisting clamp. Background Art

[0002] In modern industrial production, graphite crucible is an important container and is widely used in metallurgy, chemical industry, electronics and other fields. In the production and use of graphite crucible, it is necessary to carry out furnace lifting operation.

[0003] After searching, the Chinese patent with announcement number CN216745412U discloses a graphite crucible furnace-out auxiliary clamp. In the prior art, the graphite crucible has a high temperature after being taken out of the furnace, which makes it inconvenient to carry it directly by hand. Using other tools to carry the graphite crucible is very easy to collide or fall, resulting in damage to the graphite crucible, causing unnecessary waste and increasing the labor cost of the enterprise. By using a clamp tool to carry the graphite crucible, it is also not easy to collide or fall, reducing the labor cost of the enterprise. A rotating shaft is fixedly connected to the inner wall of the sliding track, and the rotating shaft is in contact with the surface of the connecting rod. By setting the rotating shaft, the connecting rod can be limited without causing too much friction to the connecting rod.

[0004] During use, the clamp for removing the graphite crucible from the furnace has a fixed angle of the jaws. For graphite crucibles with complex shapes, it is difficult to achieve stable and reliable clamping. Safety accidents such as the crucible slipping may easily occur during the lifting process, affecting production efficiency and operation safety. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, the utility model provides a graphite crucible furnace lifting clamp to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a graphite crucible unloading hoisting clamp, comprising a fixing box, the outer side of which is provided with a clamping mechanism;

[0007] The clamping mechanism includes a square fixing box, which is fixed to the outside of the fixing box, a fixing shell fixedly connected to the top of the fixing box, a motor fixedly installed on the bottom of the inner wall of the fixing shell, a first bevel gear fixedly connected to the output end of the motor, a plurality of second bevel gears meshed with the top of the first bevel gear, a threaded rod fixedly connected to the inside of the second bevel gear, a threaded sleeve threadedly connected to the outside of the threaded rod, a connecting slide rod fixedly connected to the bottom of the threaded sleeve, a through slide groove is provided on the bottom surface of the square fixing box, a movable plate is fixedly connected to the bottom of the movable plate, a rotating clamping plate is installed, a plurality of friction blocks are provided on one side of the rotating clamping plate, and an angle adjustment mechanism is provided between the movable plate and the rotating clamping plate.

[0008] Preferably, the angle adjustment mechanism includes a groove, the groove is opened on the bottom surface of the movable plate, a rotating block is provided inside the groove, and a fixing bolt is rotatably connected to the inner wall of the groove.

[0009] Preferably, the outer side of the fixing bolt is fixedly connected to the rotating block, and the fixing bolt is rotationally connected to the movable plate.

[0010] Preferably, a thread is provided on the outer surface of one end of the fixing bolt, and a fixing nut is connected to the outer thread of the fixing bolt.

[0011] Preferably, a fixing column is fixedly connected to the top of the fixing shell, and a fixing sleeve is provided on the outer side of the fixing column.

[0012] Preferably, a reinforcing steel rope is fixedly connected between the fixing sleeve and the square fixing box, and a lifting hook is fixedly installed on the top of the fixing column.

[0013] Preferably, the motor output end passes through the fixing box and extends into the interior of the fixing box, the connecting slide rod is slidably connected to the through slide groove, and the fixing box and the square fixing box are both rotationally connected to the threaded rod.

[0014] The technical effects and advantages of this utility model are:

[0015] By setting a clamping mechanism and an angle adjustment mechanism, a motor drives the bevel gear to rotate the threaded rod, so that the threaded sleeve moves, and then drives the movable plate and the rotating clamping plate to move, so that graphite crucibles of different sizes can be clamped, which greatly improves the applicability of the clamp. By rotating the fixing bolt and the fixing nut, the angle of the rotating clamping plate can be adjusted, so that it is convenient to clamp and hoist graphite crucibles of different shapes, increasing the flexibility of the clamp, and being able to adapt to crucibles of various complex shapes, thereby improving work efficiency. At the same time, the threaded rod and the threaded sleeve are locked by the stress between the threads to prevent the clamping jaws from being accidentally loosened. The four-jaw design makes the clamping force more evenly distributed on the crucible.

[0016] The rotating clamp plate, equipped with friction blocks, increases friction with the graphite crucible, ensuring effective clamping. During the hoisting process, the crucible is prevented from slipping even under certain vibrations and external forces, improving operational safety. The motor-driven clamping operation eliminates the need for manual adjustment, significantly improving operational convenience and efficiency. A fixed sleeve and reinforced steel ropes enhance the overall stability of the clamp during hoisting. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] As attached Figure 1-5 The graphite crucible lifting clamp shown includes a fixing box 1, and a clamping mechanism is provided on the outside of the fixing box 1;

[0025] The clamping mechanism includes a square fixed box 2, which is fixed on the outside of the fixed box 1. The top of the fixed box 1 is fixedly connected to a fixed shell 3, and a motor 4 is fixedly installed on the bottom of the inner wall of the fixed shell 3. The output end of the motor 4 is fixedly connected to a first bevel gear 5, and a plurality of second bevel gears 6 are meshed on the top of the first bevel gear 5. The inside of the second bevel gear 6 is fixedly connected to a threaded rod 7, and the outer side of the threaded rod 7 is threadedly connected to a threaded sleeve 8, and the bottom of the threaded sleeve 8 is fixedly connected to a connecting slide rod 9. A through slide groove 10 is provided on the bottom surface of the square fixed box 2, and a movable plate 11 is fixedly connected to the bottom of the connecting slide rod 9. A rotating clamping plate 12 is installed at the bottom of the movable plate 11, and a plurality of friction blocks 13 are provided on one side of the rotating clamping plate 12. An angle adjustment mechanism is provided between the movable plate 11 and the rotating clamping plate 12.

[0026] As attached Figure 1-4As shown, the angle adjustment mechanism includes a groove 14, which is opened on the bottom surface of the movable plate 11, and a rotating block 15 is provided inside the groove 14. A fixing bolt 16 is rotatably connected to the inner wall of the groove 14, and the outer side of the fixing bolt 16 is fixedly connected to the rotating block 15, and the fixing bolt 16 is rotatably connected to the movable plate 11. A thread is provided on the outer surface of one end of the fixing bolt 16, and a fixing nut 17 is threadedly connected to the outer side of the fixing bolt 16, which facilitates the adjustment of the angle of the rotating clamping plate 12 so that it can be suitable for graphite crucibles of different shapes.

[0027] As attached Figure 1 As shown, a fixed column 18 is fixedly connected to the top of the fixed shell 3, a fixed sleeve 19 is provided on the outer side of the fixed column 18, a reinforcing steel rope 20 is fixedly connected between the fixed sleeve 19 and the square fixed box 2, and a lifting hook 21 is fixedly installed on the top of the fixed column 18 to improve the stability of the overall clamp when lifting the graphite crucible.

[0028] As attached Figure 2-5 As shown, the output end of the motor 4 passes through the fixed box 1 and extends to the inside of the fixed box 1, and the connecting slide rod 9 is slidably connected to the through slide groove 10. The fixed box 1 and the square fixed box 2 are both rotationally connected to the threaded rod 7, so that the threaded rod 7 can rotate inside the square fixed box 2, thereby driving the movable plate 11 and the rotating clamping plate 12 to move through the threaded sleeve 8 and the connecting slide rod 9.
