Background
The graphite crucible is a tool matched with a smelting furnace, the requirement on high temperature resistance is high, and in actual production, the crucible can be placed into or moved out of the smelting furnace only by a hoisting mode because the position of the crucible in the smelting furnace is fixed. In prior art, some hoists adopt the flat belt formula, weave through the fiber rope, and intensity is fine, but can not hoist under the hot attitude, but must wait to adjust after the crucible cools off, so not only waste many non-production time, efficiency is very low, operates inconvenient moreover. Some adoption struts the crucible opening and presss from both sides the back and lifts by crane the removal, but graphite belongs to brittle material, struts through strut opening mode and lifts by crane the removal and very easily with crucible pressure-bearing fracture, in addition the crucible is in the state of being heated for a long time, the crucible is being heated, the atress department damages very easily, the life of general crucible is not long, manufacturing cost is higher, so how can prolong the life of crucible, it is the key of saving manufacturing cost to conveniently lift by crane the removal, consequently must design neotype graphite crucible hoist.
Disclosure of Invention
The utility model aims at providing a graphite crucible hoist solves traditional crucible hoist structure complicacy, and the inconvenient problem of operation not only can realize dismantling the safety of crucible under high temperature state, adopts the tight method of lifting by crane of crucible outer wall clamp moreover, safe and reliable more.
The utility model adopts the technical proposal that: the utility model discloses an adjustable hanger for graphite crucible, which comprises a hanging ring, a hanging rod and a clamping jaw, wherein the lower part of the hanging ring is connected with the hanging rod, the hanging rod is a long screw rod, and the lower end of the hanging rod is connected with a fixed column at the upper end of a support; a nut tightening block is arranged on the suspension rod, a sliding sleeve is arranged at the lower part of the nut tightening block, a spring is sleeved on the suspension rod between the sliding sleeve and the fixed column, and the upper part and the lower part of the spring are limited by the sliding sleeve and the fixed column respectively and are in a compressed state; the upper ends of the three long supporting rods are hinged on the sliding sleeve in an equal circumferential angle distribution mode, and the lower ends of the three long supporting rods are connected with clamping jaws; one ends of the three short supporting rods are hinged on the fixing column in an equal circumferential angle distribution mode, and the other ends of the three short supporting rods are hinged in the middle of the three long supporting rods respectively.
The nut tightening block is provided with two symmetrical extending handles.
The clamping jaw is arc-shaped and matched with the crucible, and a transverse anti-slip groove is formed in the working surface of the inner side of the clamping jaw.
The clamping jaw is connected with the long supporting rod through a bolt, and the angle of the working face of the clamping jaw is adjustable.
The support comprises a disc at the lower part, a support column is connected to the disc, and a fixing column is connected to the upper end of the support column.
The utility model has the advantages that: the utility model discloses have certain regulating power, the installation is simple. When the crucible needs to be disassembled, the separation can be realized only by rotating the nut screwing block, pressing the spring and opening the supporting rod. The utility model discloses simple structure, convenient operation, and firm reliable, the crucible receives the extrusion force very little when lifting by crane, can not receive the pressurized damage, has prolonged the life of crucible, does not need wait stove cooling moreover and just can lift by crane, has shortened non-production time by a wide margin, improves the efficiency, reduction in production cost.
