Abstract
An explosion-proof operation column solves the problems that a structure of an existing explosion-proof operation column is simple, and safety performance is bad. The explosion-proof operation column comprises an operation column box and an operation panel which covers the operation column box. Electrical apparatus elements are placed in the operation column box. Two button switches which are used for controlling the electrical apparatus elements to be connected and disconnected are placed on the operation panel. A conversion main switch is placed on the operation panel. The conversion main switch is connected with the button switches in an electric mode. The explosion-proof operation column has the advantages that the conversion main switch is added, the button switches are out of action when the conversion main switch is closed, faulty operations such as pressing the button switches carelessly are avoided, safety factor is improved, and service life of the product can be prolonged indirectly.
Description
Technical field
The utility model relates to a kind of explosive operation post.
Background technology
Along with the develop rapidly of the industries such as oil, chemical industry, mining industry, the use of explosive operation post in producing, store in a warehouse, rescuing is more and more extensive, and kind is more and more.Because explosive operation post produces electric spark inevitably in when work, they will cause the generation of explosion accident in case meet with the explosive gas mixture of production or rescue site, directly jeopardize national wealth and citizen's life security.
Existing explosive operation post generally comprises casing, is located at electric elements and guidance panel in the casing, and guidance panel is provided with starting button and the stop button of electric elements work in the control casing.Although such structure is fairly simple, if the staff can make the electric elements misoperation because of carelessness by to button, have potential safety hazard, and misoperation also reduces the useful life of electric elements easily.
Summary of the invention
Simple in structure for solving in the background technology existing explosive operation post, the problem of poor safety performance, the utility model provides a kind of explosive operation post.
The technical solution of the utility model is: a kind of explosive operation post, comprise that operation post casing and lid place the guidance panel on the operation post casing, be provided with electric elements in the described operation post casing, described guidance panel is provided with two push-button switches that are used for the switching of control apparatus element, also be provided with the conversion master switch on the described guidance panel, described conversion master switch is electrically connected with push-button switch.
As a kind of improvement of the present utility model, also be provided with the indicator light of energy indication button switch operating state on the described guidance panel.
The beneficial effects of the utility model are, increase the conversion master switch, so that conversion master switch push-button switch when closing is inoperative, can effectively avoid running into because of carelessness the misoperations such as push-button switch, increase coefficient of safety, also can indirectly increase the useful life of product simultaneously.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure, 1, the operation post casing; 2, guidance panel; 3, push-button switch; 4, conversion master switch; 5, indicator light.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By shown in Figure 1, a kind of explosive operation post, comprise that operation post casing 1 and lid place the guidance panel 2 on the operation post casing 1, be provided with electric elements in the described operation post casing 1, described guidance panel 2 is provided with two push-button switches 3 that are used for the switching of control apparatus element, also be provided with conversion master switch 4 on the described guidance panel 2, described conversion master switch 4 is electrically connected with push-button switch 3.Specifically, when changing master switch 4 at the state of opening, push-button switch 3 works, and namely presses the button switch 3, and the electric elements in the operation post casing 1 have corresponding action; When the state of conversion master switch 4 in closure, push-button switch 3 does not play control action to the electric elements in the operation post casing 1, has avoided misoperation thereby play, and has increased the fail safe of product.Also be provided with the indicator light 5 of energy indication button switch 3 operating states on the described guidance panel 2.The beneficial effects of the utility model are, increase the conversion master switch, so that conversion master switch push-button switch when closing is inoperative, can effectively avoid running into because of carelessness the misoperations such as push-button switch, increase coefficient of safety, also can indirectly increase the useful life of product simultaneously.Being arranged so that of indicator light, product can be known the state that shows push-button switch of living in use, further improve fail safe.
Every technical staff's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
