Description

Technical Field

[0001] The utility model relates to a lifting tool for a carbon material crucible, belonging to the technical field of engineering lifting tools. Background Art

[0002] Chinese Utility Model Patent CN202320263727.3 discloses a crucible lifting tool, which includes: a clamping piece provided with a plurality of vertical rope-passing holes; a lifting head arranged on the upper side of the clamping piece, the lifting head includes a lifting ring and a steel wire rope, and the steel wire rope passes through the rope-passing holes on the clamping piece according to a predetermined rope-passing method, so that at least two sections of steel wire ropes for supporting the crucible are formed at the bottom of the crucible lifting tool; the rope ends of the steel wire ropes are fixed to the lifting head. This disclosure solves the problems of space limitation between the crucible and the heater and the safety risk of crucible lifting, and can effectively improve the disassembly, assembly and overall lifting efficiency of the lifting tool. However, the above-mentioned lifting tool can only lift a single crucible at a time and cannot realize the simultaneous lifting of multiple crucibles at a time, which increases the waiting time for on-site high-temperature calcination operations, is not conducive to reducing energy consumption, and has certain defects in use. Summary of the Invention

[0003] Aiming at the problems existing in the above background art, the utility model discloses a lifting tool for a carbon material crucible, which can realize the simultaneous lifting of multiple crucibles at a time, improving the lifting efficiency and lifting safety.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A lifting tool for a carbon material crucible includes a lifting beam, on which a plurality of lifting holes are evenly arranged. Two ear hooks and a plurality of non-ear hooks are detachably connected in the lifting holes. The two ear hooks are symmetrically distributed on the left and right sides of the lifting beam, and the plurality of non-ear hooks are symmetrically distributed at the remaining positions on the lifting beam except the installation positions of the ear hooks; crucible tong mechanisms are suspended on the ear hooks and non-ear hooks. The crucible tong mechanism includes a lifting ring, at the bottom of which a first transmission rod and a second transmission rod are hinged. The other ends of the first transmission rod and the second transmission rod are respectively hinged to a first clamping rod and a second clamping rod. The middle parts of the first clamping rod and the second clamping rod are hinged to form a scissors brace structure, and the free ends of the first clamping rod and the second clamping rod are both provided with clamping plates with an arc-shaped opening, and the openings of the two clamping plates face each other.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The lifting tool for crucibles designed in this application utilizes the cooperation between various link mechanisms, enabling two arc-shaped clamping plates that fit the outer peripheral surface of the crucible to clamp the crucible. This tight clamping method is convenient and labor-saving in operation, improves the stability when lifting the crucible, and effectively prevents the crucible from tilting or even falling during lifting. Additionally, by using the lifting beam and setting the corresponding number of crucible tong mechanisms according to the number of furnace hearths, the transfer efficiency of the crucibles is improved, and the waiting time for furnace startup is shortened.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] As Figures 1-3 shown, a lifting tool for carbon material crucibles includes a lifting beam 1. A plurality of lifting holes 2 are evenly arranged on the lifting beam 1. Two hooks with ears 3 and a plurality of hooks without ears 4 are detachably connected in the lifting holes 2. The two hooks with ears 3 are symmetrically distributed on the left and right sides of the lifting beam 1, and the plurality of hooks without ears 4 are symmetrically distributed at the remaining positions on the lifting beam 1 except the installation positions of the hooks with ears 3. Crucible tong mechanisms 5 are suspended on both the two hooks with ears 3 and the plurality of hooks without ears 4. The crucible tong mechanism 5 includes a lifting ring 51. The bottom of the lifting ring 51 is hinged with a first transmission rod 52 and a second transmission rod 53. The other ends of the first transmission rod 52 and the second transmission rod 53 are respectively hinged with a first clamping rod 54 and a second clamping rod 55. The middle parts of the first clamping rod 54 and the second clamping rod 55 are hinged to form a scissors bracing structure, and the free ends of the first clamping rod 54 and the second clamping rod 55 are both provided with clamping plates 56 with an arc-shaped opening, and the openings of the two clamping plates 56 face each other.

[0013] Meanwhile, in order to further increase the clamping force, anti-slip blocks made of rubber are installed on the inner sides of the openings of the two clamping plates 56.

[0014] When in use, two ear-hooked hooks 3 on the lifting beam 1 are connected to the overhead crane hook by using a sling. Subsequently, the two clamping plates 56 are sleeved on the crucible. The lifting beam 1 is pulled upward. By virtue of the self-weight of the crucible, the first transmission rod 52, the second transmission rod 53, the first clamping rod 54 and the second clamping rod 55 then move upward, and the two clamping plates 56 clamp the crucible inward. Since the lengths of the first clamping rod 54 and the second clamping rod 55 are greater than the lengths of the first transmission rod 52 and the second transmission rod 53, the relative displacement is larger, and the clamping stroke also increases accordingly, which better improves the stability and clamping degree of the crucible during the lifting process. After the crucible is lifted to the designated position, the pulling force on the lifting beam is cancelled, and the crucible uses its own weight to reset the link mechanism. The crucible is not subject to the downward pressure of the lifting tool, realizing easy disassembly.
