Summary of the invention
The technical problem to be solved is to provide a kind of development machine of can following and carries out the device of safe efficient supporting.
For solving above-mentioned technical problem, the technical solution adopted in the present invention: self-propelled development end advance timbering, including operating desk, frame, first running part, second running part, back timber, multiple telescopic back timber columns, multiple lower support cylinders, back timber, forestope, motor and hydraulic oil container, described operating desk is arranged on frame top, the back timber column of multiple supporting top beam also it is arranged at intervals with in described frame top both sides, and between each two back timber column relative to thirty years of age of the frame both sides, it is equipped with tie-beam, a tie-beam above operating desk is provided with hydraulic oil container and motor, described first running part, second running part be symmetricly set on bottom frame and the first running part and the second running part structure identical, the plurality of lower support cylinder is symmetricly set on two ends bottom frame；
Diagonal brace oil cylinder and a connecting piece it is hinged with bottom described back timber, the second connection sheet it is hinged with bottom described forestope, and second to connect sheet and a connecting piece hinged, the cylinder body of described diagonal brace oil cylinder is connected with back timber, the pin joint of piston rod and a connecting piece, the second connection sheet is hinged.
Inner barrel movable set, in the inside of outer cylinder body, is provided with scalable oil cylinder at inner barrel inner vertical, and the piston rod end of scalable oil cylinder is connected with bottom back timber, cylinder body is arranged on inner barrel inwall.
Described first running part, the second running part are crawler type walking mechanism.
Being provided with tripod on a tie-beam above described operating desk, described hydraulic oil container and motor are arranged on tripod.
Piston rod end at described lower support cylinder is provided with the pad being easy to support ground.
The plurality of telescopic back timber column quantity is five, and the plurality of lower support cylinder quantity is four.
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, second running part is walked along development end, until top is to a steamed bread of corn, then staff operates handle at operating desk, multiple back timber columns are risen, make frame stable to the support of lower support cylinder, 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, after support work completes, the present invention steps back, development machine continues the next working cycles of beginning that moves ahead, the present invention compares mechanization degree height compared with the gib of technical operation personnel, security 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 complex road condition of development end, front line stabilization.
Three, the present invention is by being symmetrical arranged four lower support cylinders bottom frame so that present invention ground supports of frame in Bracing Process is more firm.
