Crucible lifting appliance capable of automatically unhooking and crucible lifting method

Abstract

The invention discloses a crucible lifting appliance capable of automatically unhooking and a crucible lifting method, and belongs to the technical field of carbon-carbon product processing, the crucible lifting appliance comprises a pull rod, a lifting ring is arranged at the upper end of the pull rod, the lifting ring is connected with a lifting hook of a travelling crane, the pull rod is provided with a side hook below the lifting ring, and the lower end of the pull rod is hinged with support arms which are symmetrically arranged to form a scissor fork; the supporting arms on the two sides are connected through a connecting piece, the connecting piece is of a flexible structure, a limiting ring is arranged on the connecting piece, an unhooking ring is connected to the limiting ring, an unhooking rope is connected to the unhooking ring, and the upper end of the unhooking rope is limited through a limiting piece on the pull rod. The invention provides a lifting appliance capable of realizing automatic unhooking, can realize lifting of products in a deep well type furnace within 100 DEG C, and is simple in structure, convenient to operate, less in manual operation, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of carbon-carbon product processing, in particular to a crucible hanger that can be automatically decoupled and a crucible hoisting method. Background technique [0002] Graphite crucibles or carbon-carbon crucibles are supplied in large quantities as thermal field consumables. Before leaving the factory, each crucible must go through processes such as blank, densification, and processing. The weight is more than 60 kg, and when multiple suits are transported, it reaches more than 200 kg. The manual handling efficiency is low and safety accidents are prone to occur. [0003] The existing crucible spreader or hanger on the market is put into the hanger from the wide-mouth end of the crucible, and the clamping movement is realized by the friction between the hanger and the inner wall of the crucible. There are several main problems in this hoisting method: First, The hanger has a complex structure, heavy weig...

AI Technical Summary

Problems solved by technology

[0002] Graphite crucibles or carbon-carbon crucibles are supplied in large quantities as thermal field consumables. Before leaving the factory, each crucible has to go through process steps such as green body, densification, and processing. Each link is inseparable from the lifting and moving of the crucible. The weight is more than 60 kg, and it can reach more than 200 kg when carrying multiple sets. Manual handling is inefficient and prone to safety accidents

[0003] The existing crucible hanger or hanger on the market is put into the hanger from the wide-mouthed end of the crucible, and the clamping movement is realized by the friction between the hanger and the inner wall of the crucible. There are several main problems in this lifting method: one is The hanger has complex structure and heavy weight, and cannot get rid of manual picking in the whole process; secondly, it is difficult to realize automatic operation especially for taking products in deep well type high temperature furnace
