Abstract
The invention discloses a mechanical electrical interconnection safety device which is used for prevent on-load operation of an isolation phase-change switch in an explosion-proof vacuum electromagnetic starter, and the device comprises an isolating sleeve, a jackscrew, an isolating operation rod assembly, an isolating copper sleeve, an isolating steel sleeve, a housing front plate, an elastic shaft check ring, an operating handle, a handle gasket, a button spring, a button copper sleeve, a button baffle plate, a button rod, and a button adjustment nut. The four inner corners of the isolating sleeve are engaged with an isolating operation shaft, and the switching-on and switching-off of the isolation phase-change switch can be achieved through the rotation of the operating handle. When a button is at a free position, the button baffle plate prevents an isolating operation rod from rotating in a groove of a petaling rotating disc of the isolating operation rod assembly, and cannot control the on/off of the isolation phase-change switch. Only when the button is pressed down, can the button baffle plate be separated from the groove of the petaling rotating disc of the isolating operation rod assembly, so as to allow the free rotation of the isolating operation rod.

As shown in Figure 1, 2,2. when button is in free position, button baffle plate (14) engages with the semicircle groove of isolated operation bar assembly (3) petal rotating disk and interlocks, and stops isolated operation bar assembly (3) to rotate, can not the break-make of operation isolation phase-change switch; Only have when button spindle (15) presses power-off, button baffle plate (14) could depart from the semi-circular groove of isolated operation bar assembly (3) petal rotating disk, the semicircle groove of button baffle plate (14) and isolated operation bar assembly (3) petal rotating disk is thrown off and is unlocked, allows isolated operation bar assembly (3) rotation to isolate commutation.When insulating phase-change switch has commutated relieving button spindle (15), button spindle (15) can under the effect of button spring (12) in tow button baffle plate (14) upspring, button baffle plate (14) with isolation lever assembly (3) petal nibble engagement locking.
Beneficial effect of the present invention is compact conformation, simple, easy-to-operate, stable, reliable, is applicable to various explosion-proof vacuum electromagnetic device and moves the mechanical interlocking mechanism that device uses.For coal industry mark provides the safety utilization of electric power mechanical interlock of a kind of insulating phase-change switch operating mechanism and electrical correlation.
