Compared to the prior art the present invention has the advantages that.
One, after development machine tunnels five meters and retreats, the present invention passes through the first running part, the second running part along development end
Walking, until top is to a steamed bread of corn, then staff operates handle at operating board, by the rise of multiple back timber columns, lower support cylinder
Support frame is stablized, forestope is pulled to level by diagonal brace oil cylinder and carries out supporting, owing to anchor online story is first layered on back timber, therefore
When multiple back timber columns are by back timber top to development end top board, i.e. can use, by anchor net, top board is carried out support work, a nurse
After completing, the present invention steps back, and development machine continues the next cycle of operation of beginning that moves ahead, and the present invention is compared with technical operation personnel
Gib compare that mechanization degree is high, safety is good, supporting effect is also stable.
Two, first running part of the present invention, the second running part are crawler-type traveling, it is possible to adapt to the complicated road of development end
Condition, front line stabilization.
Three, the present invention is by being symmetrical arranged four lower support cylinders bottom frame so that the present invention is in Bracing Process
The ground supports of frame is more firm.
Four, the back timber of the present invention is designed as segmentation structure, when development end top board flatness is poor when, due to top
Beam is that each back timber joint hinged forms, therefore when multiple back timber columns rise back timber, and smooth according to top board of each back timber root section
Degree situation can preferably touch top board respectively against top board, the anchor net being at this moment layered on back timber, and the supporting effect of anchor net is more preferable
More stable.
