Abstract
The utility model relates to the field of an electric control box of a coal mine laneway digging machine, in particular to a remote controller of an electric control box of a digging machine, which is used for switching off an upper stage electricity supplying power supply when a box door of the electric control box is opened. The device is provided with a stroke switch and a trigger, wherein the stroke switch is arranged on the electric control box, and the trigger is arranged on the door of the electric control box, and corresponds to the stroke switch. The utility model adds the stroke switch and the trigger in the electric control box, and through the control by a control circuit, the upper stage electricity supplying power supply of the digging machine is switched off when the box door of the electric control box is opened. The utility model solves the problem that the potential safety hazard is great when only a power supply in the electric control box under a transformer arranged in the electric control box is switched off when the electric control box of the existing digging machine is opened, and the safety performance of the existing digging machine is improved.
Description
Affiliated technical field
The utility model relates to the electric cabinet field of coal mine roadway development machine, is specially a kind of remote control of development machine electric cabinet, cuts off the upper level power supply of development machine when being used to open the electric cabinet chamber door.
Background technology
Development machine only cuts off the control power supply of development machine when opening electric cabinet at present, also there is the high voltage of 1140V in the transformer leading-in end in the electric cabinet, as excessive at high gas or coal dust or be easy to generate under the electric spark situation on fire, cause the generation that electric spark is on fire or explode easily, have potential safety hazard.
The utility model content
In order to improve the security performance of development machine, reduce safety of coal mines hidden danger, the purpose of this utility model is to provide a kind of remote control of development machine electric cabinet, has increased travel switch and trigger in electric cabinet, cuts off development machine upper level power supply when opening the electric cabinet chamber door.The utility model has solved existing development machine and only cut off in the electric cabinet power supply in the electric cabinet below the transformer when opening electric cabinet, and the problem that potential safety hazard is big has improved the security performance of existing development machine.
The technical scheme that the utility model adopted is:
A kind of remote control of development machine electric cabinet, this device is provided with travel switch, trigger, and travel switch is installed on the electric cabinet, and trigger is installed on the automatically controlled chamber door, and trigger is corresponding with travel switch.
The remote control of described development machine electric cabinet, travel switch is installed on the electric cabinet by the travel switch seat.
The remote control of described development machine electric cabinet, travel switch seat are fixed on the electric cabinet of development machine; Perhaps, the electric cabinet of travel switch seat and development machine is integral.
The remote control of described development machine electric cabinet, trigger are fixed on the automatically controlled chamber door of development machine; Perhaps, the chamber door of trigger and development machine is an one.
The remote control of described development machine electric cabinet, travel switch are connected on the control circuit of development machine electric cabinet.
The remote control of described development machine electric cabinet, the output connection processing device of travel switch, the output of processor connect the control end of development machine upper level power supply by the control line of cable.
The remote control of described development machine electric cabinet, travel switch are two.
The remote control of described development machine electric cabinet, travel switch are normally closed travel switch.
The beneficial effects of the utility model are:
1, the utility model is fixed on travel switch in the electric cabinet, trigger is fixed on the electric cabinet chamber door, and when opening the electric cabinet chamber door, trigger triggers travel switch, travel switch is used to cut off control circuit, cuts off the power supply of development machine upper level by circuit for remotely controlling.
2, adopt the utility model, can cut off the upper level power supply when meeting accident, increased coefficient of safety, it is little to have potential safety hazard compared with prior art, safety of coal mines coefficient advantages of higher.
Description of drawings
Fig. 1 is the utility model circuit controling drawing.
Fig. 2 is the utility model structure chart.Among the figure: 1 electric cabinet; 2 travel switch seats; 3 travel switches; 4 triggers; 5 automatically controlled chamber doors.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the utility model development machine electric cabinet remote control, on the control circuit of development machine electric cabinet, be in series with two travel switches: travel switch I and travel switch II, the output connection processing device of travel switch, the output of processor connect the control end of power supply by the control line of cable.When opening the electric cabinet chamber door, corresponding travel switch I or travel switch II disconnect, control circuit is disconnected, by described control circuit cut-off signal is passed to processor, the output of processor is realized the Long-distance Control of development machine power supply by the control line of cable, cut off circuit for remotely controlling, realize the long-range outage of development machine, cut off the upper level power supply of development machine.
Because the electric cabinet in the utility model has two automatically controlled chamber doors, so adopted " two " travel switches: the automatically controlled chamber door that the travel switch I is corresponding different respectively with the travel switch II.
In the utility model, travel switch is normally closed travel switch.
As shown in Figure 2, the remote control of the utility model development machine electric cabinet mainly partly is made of travel switch seat 2, travel switch 3, trigger 4 etc.Travel switch 3 is installed on the electric cabinet by travel switch seat 2, and travel switch seat 2 is fixed on the electric cabinet 1 of development machine, also can be integral with the electric cabinet 1 of development machine.Trigger 4 is fixed on the automatically controlled chamber door 5 of development machine, can be one with the automatically controlled chamber door 5 of development machine also.Travel switch 3 is installed on the travel switch seat 2, and trigger 4 is corresponding with travel switch 3, is used for the closure or openness of travel switch 3.
When opening electric cabinet chamber door 5, trigger 4 leaves travel switch 3, and the control circuit at travel switch 3 places disconnects, and by control circuit signal is passed to processor, and processor passes to remote power supply with the remote power supply cut-off signal, the remote power supply outage.
More than a kind of remote control provided by the utility model is described in detail, use specific case principle of the present utility model and execution mode are set forth, the explanation of above case study on implementation just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
