Problems solved by technology

When it is necessary to open the gate, use the electric gate first, and then manually open the gate if it cannot be separated. Since it is used separately, the time will be prolonged, the operation is inconvenient, and the reliability is poor, which is likely to cause accidents.

Embodiment Construction

[0010] Such as Figure 1-4 As shown, an electromechanical two-in-one opening operating mechanism, which includes an electric electric opening element 4 and a mechanical opening element 5, is characterized in that it also includes an actuator, the structure of the actuator is, in the opening The housing of the device is provided with a rotary opening handle 1, which is connected to an opening shaft 2 and the opening shaft 2 is connected with a switching fork 3. When the switching fork 3 rotates, the shift head first Press on the electric opening element, the electric opening element selects the micro switch 4, and then it is pressed against the mechanical opening element 5 when it continues to rotate.

[0011] From figure 1 It can be seen that in the initial state, the opening handle 1 is in the horizontal position, and neither the micro switch 4 nor the mechanical opening element 5 has an opening command issued.

[0012] Turn the opening handle 1 counterclockwise, and drive the op...

Abstract

The invention discloses an electric and mechanical two-in-one operation mechanism for brake separation. The mechanism comprises an electric brake separation element, a mechanical brake separation element and an execution mechanism, wherein the execution mechanism is provided with a rotary type brake separation handle on a shell of a brake separation device and the brake separation handle is connected with a rotary shaft; the rotary shaft is connected with a brake separation shifting fork; when the brake separation shifting fork rotates, a shifting head is firstly pressed on the electric brake separation element; when the brake separation shifting fork continually rotates, the shifting head is ejected on the mechanical brake separation element. According to the invention, the brake separation of a switch can be more conveniently, fast and reliably realized and is safer. And the quantity of flameproof holes on the shell of the device is reduced so that explosion-proof requirements of coal mines are easy to meet.

Description

Technical field [0001] The invention relates to explosion-proof switches such as vacuum feed switches, vacuum electromagnetic starters, etc., and in particular to an opening device of an explosion-proof switch. Background technique [0002] In the coal electrical industry, the opening of explosion-proof switches such as vacuum feed switches and vacuum electromagnetic starters are mainly manual button type electrical button opening and button push rod type mechanical opening. The two types of opening are used separately. When it is necessary to open the brake, first use the electric opening, and then use the manual opening when it cannot be opened. Because it is used separately, the time is prolonged, the operation is inconvenient, and the reliability is poor, and it is easy to cause accidents. Summary of the invention [0003] The purpose of the present invention is to change the shortcomings of the traditional button-type electrical opening and button-type mechanical opening sepa...
