A mine operation system and its multi-door interlocking electrical equipment

Abstract

The invention discloses multi-gate electrical equipment, including a lock shaft and an isolation shaft. The lock bolt shaft is in transmission connection with a first moving part and a second moving part. The second moving part is provided with a lock hook used for locking a first protection door in a moving direction. The isolation shaft is used for achieving switching on and switching off of an isolation switch through self rotation and is coaxial with the first moving part in the moving direction. The isolation shaft is also provided with a cam gear, and the cam gear is rotatably clamped with a lock clamp of a second protection door. The lock shaft rotates to clamp the second moving part with the lock hook and to clamp the cam gear with the lock clamp when the first moving part departs from the isolation shaft. When the first moving part is tightly clamped with the isolation shaft, the second moving part is disengaged with the lock hook, and the cam gear is disengaged with the lock clamp. The invention ensures safety and usage convenience in the usage process of the electrical equipment. The invention also provides a mine operation system including the multi-gate electrical equipment.

Description

Technical field [0001] The invention relates to the technical field of mine operations, in particular to a multi-door interlocking electrical equipment. In addition, the present invention also relates to a mine operation system including the above-mentioned multi-door interlocking electrical equipment. Background technique [0002] In modern coal mine underground operations, it is usually required that the doors of explosion-proof electrical equipment be mechanically interlocked with the isolation switch. Before the isolation switch is disconnected, the equipment enclosure should maintain the explosion-proof performance, that is, the equipment door is required to remain closed before the isolation switch is disconnected. [0003] In the common technology at this stage, the method of coaxial control of the isolating switch and the door of the device can be used to control a single door and the isolating switch, and the setting angle of the door and the isolating switch is relatively...

AI Technical Summary

Problems solved by technology

[0003] In the commonly used technology at this stage, the coaxial control method of the isolating switch and the door of the equipment can be used to control a single door and isolating switch, and the setting angle of the door and isolating switch is relatively single

Although this method can better realize the control of the two devices, there are problems in safety, and it cannot guarantee that the equipment door remains locked during the closing and opening process of the isolating switch.
