Abstract

The invention discloses a locking device. The locking device is used for locking an isolation switch (3), the isolation switch (3) is fixed on a baffle board (1), a protection cover (2) is at the outer periphery, and the locking device comprises a clamp ring (6) fixed at the protection cover (2), a dead bolt (5) which is mounted on the clamp ring (6) and can shield the isolation switch (3), and a lockset (4) capable of firmly locking the dead bolt (5) to shielding the isolation switch (3). The locking device effectively solves problems of external exposure of the isolation switch and illegal start of a heading machine.

Description

technical field [0001] The invention relates to the field of mining machinery safety, in particular to a locking device for an isolating switch. In addition, the present invention also relates to an isolating switch and fully mechanized excavator comprising the above-mentioned locking device. Background technique [0002] With the continuous innovation of comprehensive mechanized excavation equipment, the safety of machine equipment operation has been widely valued. Many accidents are caused by non-professional operators operating machines without permission. In the fully mechanized excavation working face, the roadheader is a large-scale head-on equipment. When personnel are performing operations such as head-on anchor net support and roadheader maintenance, all personnel are concentrated near the roadheader. At this time, the roadheader is strictly prohibited from starting. [0003] Please refer to figure 1 and figure 2 , figure 1 It is a structural schematic diagram ...
