The invention provides an interlocking device. The interlocking device is arranged on an electric control box; the electric control box comprises a circuit breaker, a first box door and a second box door; the interlocking device comprises an installation seat, a first supporting shaft, a second supporting shaft, a first supporting sheath, a second supporting sheath and a rotating shaft; the rotating shaft is provided with a groove and is connected with the circuit breaker; the first supporting sheath is used for fixing the first supporting shaft; the second supporting sheath is used for fixing the second supporting shaft; the first end of the first supporting shaft can slide in the installation seat; the second end of the first supporting shaft is clamped in the groove in a detachable way; the first end of the second supporting shaft is connected to the second supporting sheath in a slideable way; the second end of the second supporting shaft can slide in the installation seat; and the installation seat is arranged on the first box door and is used for locking the second supporting shaft through the first supporting shaft or locking the first supporting shaft through the second supporting shaft. The interlocking device provided by the invention can implement the interlocking of a circuit breaker switch and electric control box doors and is simple in structure and assembly. The invention also provides the electric control box.
Description
technical field [0001] The invention relates to the field of coal mines, in particular to an interlock device and an electric control box including the interlock device. Background technique [0002] In the field of coal mines, the electric control box is a special component of coal mine products, and it is strictly forbidden to open the door when the electric control box is electrified. As the circuit breaker is the component that controls the entire circuit in the electric control box, it is necessary to ensure that the door of the electric control box cannot be opened when the circuit breaker is turned on, and the door can only be opened when the circuit breaker is turned off. [0003] At present, most of the electric control box door and circuit breaker switch are controlled by a separate interlock device, that is, the circuit breaker itself adds an interlock device or the on-off of the circuit breaker must be controlled by a special tool, and the electric control box do...
