Description
Technical Field
The utility model relates to the field of electrical control, in particular to an explosion-proof operation column for cover opening switching.
Background
The operation column is widely applied to the fields of coke, chemical industry and mining industry. The operation column is usually arranged beside the field device and used for in-situ operation, and the control mode is single. The existing explosion-proof operation column is generally a single cavity and has a single function, and once the explosion-proof operation column is damaged, the control function can be lost, so that emergency operation control can not be performed. Therefore, there is a need for an explosion-proof operation column with novel control mode switching, multiple functions and emergency operation.
Disclosure of Invention
The utility model aims to provide an operation column with various control modes.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides an explosion-proof operation post of switching uncaps, includes the operation post body, still includes first cavity and second cavity, and first cavity and second cavity are fixed at the top of operation post body, first cavity and second cavity comprise casing and panel, and the second cavity sets up in first cavity, all are equipped with electric control part on the panel of first cavity and second cavity, set up travel switch on the second cavity, the back of first cavity panel sets up the firing pin, and the firing pin top is on travel switch after the first cavity panel is closed.
Preferably, the end surface of the contact end of the firing pin and the roller is provided with an inclined chamfer.
Preferably, the end part of the travel switch is in a roller type, and the firing pin is propped against the roller on the travel switch.
By adopting the technical scheme of the utility model, the following beneficial effects can be obtained:
The explosion-proof operation column with the cover switched is characterized in that an operation column shell is provided with two explosion-proof cavities from outside to inside; a first cavity is arranged in the shell and is provided with a first cavity electric element; and a second cavity and an electric element which are in interlocking relation with the first cavity, and an operation column for automatically switching a control mode after the cover is opened.
Drawings
The following is a brief description of what is expressed in the drawings of this specification and the references in the drawings:
FIG. 1 is a schematic view of the explosion-proof operation column;
FIG. 2 is a schematic diagram of a second embodiment of the present explosion-proof operation column;

Detailed Description
The following describes the shape, structure, mutual position and connection relation between the parts, action and working principle of the parts, etc. of the specific embodiments of the present utility model, such as the related parts, will be further described in detail by describing examples.
As shown in fig. 1 and 2, the explosion-proof operation column for switching the cover comprises an operation column body, and further comprises a first cavity 4 and a second cavity 5, wherein the first cavity 4 and the second cavity 5 are fixed at the top of the operation column body, the first cavity 4 and the second cavity 5 are composed of a shell and a panel 1, the second cavity 5 is arranged in the first cavity 4, the panel 1 of the first cavity 4 and the panel 1 of the second cavity 5 are both provided with an electric control part 2, the second cavity 5 is provided with a travel switch 3, the back of the panel 1 of the first cavity 4 is provided with a firing pin 6, and the firing pin 6 is propped against the travel switch 3 after the panel 1 of the first cavity 4 is closed. The end face of the contact end of the firing pin 6 and the roller 7 is provided with an inclined chamfer, the end part of the travel switch 3 is a roller, and the firing pin 6 is propped against the roller 7 on the travel switch 3.
The explosion-proof operation column is internally provided with two sets of identical electric control components 2, the two sets of electric control components 2 are connected into an electric device to be controlled, the electric control components 2 on the first cavity 4 are used for controlling under normal conditions, when the electric control components 2 on the first cavity 4 are damaged or fail to be destroyed under special conditions, the electric control components are propped against a firing pin 6 on the back surface of a panel 1 of the first cavity 4, the travel switch 3 acts to strike the panel 1 of the first cavity 4, and the electric control components are switched to the second cavity 5 for continuous use.
The explosion-proof operation column with the cover switched comprises an operation column shell, wherein the operation column shell is provided with two explosion-proof cavities from outside to inside; a first cavity is arranged in the shell and is provided with a first cavity electric element; and a second cavity and an electric element which are in interlocking relation with the first cavity, and an operation column for automatically switching a control mode after the cover is opened.
While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the utility model are adopted, all within the scope of the utility model.
