Abstract
The utility model discloses an electromechanical switching-off operating mechanism which comprises an electric switching-off element, a mechanical switching-off element and an implementing mechanism. The implementing mechanism is provided with a rotating switching-off handle on the shell of a switching-off device; the switching-off handle is connected with a rotating shaft; the rotating shaft is connected with a switching-off shifting fork; when the switching-off shifting fork rotates, a shifting head is first pressed on the electric switching-off element; and when the switching-off shifting fork continues to rotate, the shifting head is supported against the mechanical switching-off element. Due to the adoption of the electromechanical switching-off operating mechanism, a switch can switch off more conveniently, rapidly and reliably. In addition, the number of flameproof holes of the shell of the switching-off device decreases, and the explosion prevention requirements of a coal mine can be met.
Description
Technical field
The utility model relates to flame-proof switches such as vacuum feed switch, vacuum electromagnetic starter, relates in particular to the switching-off device of flame-proof switch.
Background technology
In the coal electrical apparatus industry, the separating brake of flame-proof switches such as vacuum feed switch, vacuum electromagnetic starter is main with the electric button separating brake of hand push button formula and the mechanical separating brake of thumb-button push rod formula mainly, and two kinds of separating brakes use separately.When the needs separating brake, use electronic separating brake earlier, use manual brake separating when inseparable again, owing to be separately to use, so will prolong in time, operation inconvenience, and poor reliability cause the accident easily.
Summary of the invention
The purpose of the utility model is to change the traditional electric separating brake of push button and the deficiency of the independent operator scheme of button type mechanical separating brake, designs the two-in-one on/off operation mechanism of a kind of motor machine.
The two-in-one on/off operation mechanism of a kind of motor machine, it comprises electronic separating brake element and mechanical separating brake element, it is characterized in that; It also comprises an actuator; Actuator is provided with rotary type separating brake handle on the housing of switching-off device, connect a separating brake rotating shaft on the separating brake handle, is connected with the separating brake shift fork in the separating brake rotating shaft; Shifting block withstood on again when being rotated further on the mechanical separating brake element at first by being pressed on the electronic separating brake element again when the separating brake shift fork rotated.
During use, only need forward the separating brake handle to upright position from horizontal level counterclockwise, make the electric separating brake of one-level, are rotated further to reach secondary machinery separating brake again.
The utility model has the advantages that: make more convenient, quick, the reliable separating brake of switch ability, safer.And the minimizing of the flame proof hole number of device case, be easy to reach the coal mine explosion-proof requirement.
Description of drawings
Position left view when Fig. 1, Fig. 2, Fig. 3 are respectively the utility model embodiment separating brake, wherein Fig. 1 represents the action initial position, and Fig. 2 represents the electrical action position, and Fig. 3 represents the action final position;
Master when Fig. 4 is the utility model embodiment separating brake looks cutaway view.
Marginal data: 1-separating brake handle, the rotating shaft of 2-separating brake, 3-separating brake shift fork, 4-sensitive switch, 5-machinery separating brake element.
Embodiment
As shown in the figure, the two-in-one on/off operation mechanism of a kind of motor machine, it comprises electronic separating brake element and mechanical separating brake element 5; It is characterized in that it also comprises an actuator, the structure of actuator is; On the housing of switching-off device, be provided with rotary type separating brake handle 1; Connect a separating brake rotating shaft 2 on the separating brake handle 1, be connected with separating brake shift fork 3 in the separating brake rotating shaft 2, shifting block was at first by being pressed on the electronic separating brake element when separating brake shift fork 3 rotated; Electronic separating brake element is selected sensitive switch 4 for use, withstands on again when being rotated further on the mechanical separating brake element 5 again.
As can be seen from Figure 1, separating brake handle 1 is at horizontal level during initial condition, and sensitive switch 4 does not all have the separating brake instruction to send with mechanical separating brake element 5.
Stir separating brake handle 1 counterclockwise, drive separating brake shift fork 3 action to position shown in Figure 2 together through separating brake rotating shaft 2, separating brake handle 1 is the 45 position with level, drives sensitive switch 4 actions this moment, sends electric separating brake instruction.
Continue to stir counterclockwise separating brake handle 1; Drive separating brake shift fork 3 through separating brake rotating shaft 2 and move together to position shown in Figure 3 with sensitive switch 4, separating brake handle 1 is in position, 80--90 ° of angle, and this moment, mechanical separating brake element 5 sent instruction; Promote the breaker mechanical separating brake; This moment, sensitive switch 4 kept operate condition, continued to send electric separating brake instruction, was in two instruction gate-dividing states this moment.
