Further, the drag conveyor is equipped with the cable of the rotatable groove body of any one of them band of content described above
Slot.
Further, the pedal centre position is equipped with 3 positioning gussets.
With the above structure, pedal need to only be rotated to horizontal position and can trampled by maintenance personnel, and coalcutter is carried out
Detection；When needing to safeguard coalcutter in mined out side, maintenance personnel only need to be by the coalcutter in the cable trough upper groove body of relevant position
Then cable dragging removes positioning pin, upper groove body is rotated, without dismantling cable trough, lower groove to suitable position
Internal water, liquid pipe and cable all can normal uses；At the end of maintenance work, only upper groove body need to be turned round horizontal position and be used in combination
Positioning pin is fixed, and electric cable for coal mining machine resets, and pedal, which is rotated to upright position, to be fixed.
Advantages of the present invention：The bolt that the cable trough of this rotatable groove body of band uses is few, and intensity is high, compact-sized, leads to
Rotation upper groove body and pedal are crossed, can vacate and safeguard space, carries out trampling operation convenient for maintenance personnel, avoids dismounting cable trough,
So that plant maintenance is more convenient, safety, and it is time saving and energy saving, meet the exploitation requirement of coal mine work area high-yield and high-efficiency.
