Pass type skip-plating and chain-separating preventing device for circular ring chain continuous hot-dip coating

Abstract

The invention discloses a pass type skip-plating and chain-separating preventing device for circular ring chain continuous hot-dip coating. The pass type skip-plating and chain-separating preventing device comprises a cylindrical cam, a circular ring chain wheel, an indexing disc and a non-return mechanism, wherein a molded line which consists of three phase sections of a negative rotation section, a static section and a positive rotation section is arranged on the cylindrical cam; a phase angle of each phase section is designed according to viscosity of a plating solution; a roller is arranged on the indexing disc; the roller and the molded line form high pair linkage; the indexing disc and the circular ring chain are coaxially mounted and are fixed in phase; a chain of the circular ringchain wheel enters one side; and the tail end of the mounting shaft of the cylindrical cam is equipped with the non-return mechanism. The pass type skip-plating and chain-separating preventing devicefor circular ring chain continuous hot-dip coating, which is realized through means such as mechanical transmission and mechanism design, is compact in structure, can realize modularized mounting anddismounting, is convenient for equipment maintenance and repair; and meanwhile, on the premise of improving operating efficiency of circular ring chain hot-dip coating, a skip-plating phenomenon at ajoint of the circular ring chain and a chain ring further can be obviously avoided.

Description

technical field [0001] The invention relates to the field of metal surface anticorrosion and wear-resisting treatment, in particular to a ring chain continuous passing type hot-dip plating leak-proof plating off-chain device. Background technique [0002] The working environment of the mining circular link chain is relatively special. In addition to meeting the strength requirements, it must also have excellent anti-corrosion and wear-resistant properties. At present, when the anti-corrosion and wear-resistant coating is applied to the surface of the mining circular link chain, the immersion treatment process is generally used. However, this process takes a long time and is inefficient, and it is only suitable for short-length circular chains. Otherwise, the plating solution container will be enlarged, and it will be difficult for medium melting time, plating solution replenishment frequency and slag removal. Even equipment maintenance and other aspects bring problems. [...

Problems solved by technology

However, the existing technical problem is that because the circular link chain is in a tensioned state when it passes through the plating solution continuously, the gap between the links is small, and the plating solution has a high viscosity and poor fluidity, so it is difficult to fully immerse into the joints of the links. , although there are many types of flux as auxiliary, but still often occur in the case of missed plating
