Description

Technical Field

[0001] The utility model belongs to the technical field of plug disconnecting tools, in particular to a tool for disconnecting the plug of a continuous casting crystallizer width adjustment system. Background Art

[0002] As we all know, the crystallizer width adjustment system in the continuous casting area is connected to the operating system using two cables with 48 pins and 72 pins. The cable plug is fixed on the crystallizer, and the cable connection is a round plug. Since the crystallizer generates a lot of steam and heat during production and the space of the crystallizer is limited, the control box of the crystallizer is relatively small. The space for plugging and unplugging the plug can only extend half of the hand. The plug interface is easily expanded due to heat, making it difficult to unscrew it by hand, so it is necessary to use the power of tools to unplug it without damaging the plug.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0017] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.
