Generally comprise hydraulic motor travel motor F6 and walking reversal valve F5.Locating oil cylinder E4 and the oil circuit of continuous milling machine walking mechanism are linked,
When continuous milling machine displacement, the limiting piston bar E41 of locating oil cylinder E4, which is withdrawn, drives limit slide bar E2 from the position limited gear E1
Slot in extraction release to rolling net axis C limit, the continuous milling machine do not walk the time limit position oil cylinder E4 reset spring E43 drive under
It stretches out limiting piston bar E41 and then limit slide bar E2 is pushed into the tooth socket of the position limited gear E1, realize the limit of rolling net axis C
Locking.
The fuel feeding working principle of locating oil cylinder E4: when continuous milling machine walking mechanism will walk, walking reversal valve F5 movement is row
Walk hydraulic motor F6 fuel feeding, while pressure oil output is to the first shuttle valve F1, and then by the second shuttle valve F2, third shuttle valve F3, into
Enter the limit oil inlet E42 of locating oil cylinder E4, releases the limit to rolling net axis C.If wanting to release when continuous milling machine is not walked
The limit for rolling net axis C, then can be passed through hydraulic oil to the limit oil inlet E41 of locating oil cylinder E4 by hand-operated direction valve F4, together
Sample can achieve the purpose for releasing rolling net axis limit.When wherein hand-operated direction valve F4 does not need to unlock by hand, manual reverse of direction
Pressure oil is switched to oil return box off-load by valve F4；When manual operation being needed to unlock, the handle for operating hand-operated direction valve F4 is real
Pressure oil is switched to third shuttle valve F3 by the commutation of existing valve, and pressure oil enters locating oil cylinder E4, driving limit by third shuttle valve F3
Position oil cylinder E4 movement unlocks.

Cylinder limits oil inlet E42 no pressure when continuous milling machine is not walked, and reset spring E53 pushes one-way cylinder piston rod (to limit
Position piston rod E41), limiting piston bar E41 pushes limit slide bar E2 to stretch out again, and the tip of limit slide bar E2 is inserted into position limited gear E1
Tooth socket in, position limited gear E1 is stuck, so realize will entire rolling net axis C1 is stuck is not able to rotate, linked network disk C4 catches on flexibility
Net 4, net volume C41 cannot continue to be unfolded, and the expansion net C42 at rear portion is tightened, and worker is in the development roof timbering operation off the net tightened.
When continuous milling machine walking, pressure oil is passed through to limit oil inlet E42 by hydraulic system, pressure oil compresses reset spring E43,
It drives the limiting piston bar E41 of locating oil cylinder E4 and then limit slide bar E2 is driven to withdraw, limit slide bar E2 from position limited gear E1's
Deviate from tooth socket, release the limit to position limited gear E1, and then relieves the limit to rolling net axis C.Since expansion net C42 is
It is fixed on back via Bolt System, therefore when continuous milling machine is walked forward, since the traction of expansion net C42 is made
With rolling net axis C passive rotation, net volume 41 follows expansion to become expansion automatically and nets C42.The process need not human intervention, by hydraulic
System interlink is completed.Wherein net volume 41 can be directly placed on net volume storage rack A, can also be installed on net volume storage rack A
Net volume 41 is wound and is fixed in shaft by shaft.It is tightened as long as the gravity or pulling force of net volume 41 can be such that expansion net C42 reaches
State.The working principle of damping mechanism D: it adjusts plug screw D5 and compresses damping spring D2, damping spring D2 pushes damping slide bar
D1 stretches out, in the head insertion damping disk cover D4 of damping slide bar D1.When rolling net axis C is to be rotated, it is necessary to have enough tractive force,
The resistance that damping slide bar D1 can just be overcome, is pushed up back.In this way it is prevented that the rolling automatic back rotation of net axis C leads to net volume
41 expansion are excessive, expansion net 42 can not be tightened.
