Description
Technical field
The present invention relates to a kind of digging type development machine, especially relate to the broken digging type development machine of a kind of multi-arm.
Background technology
The breaking excavation development machine of multi-arm is to reach f≤3 with digging (shovel) bucket or the direct excavating rock of milling head at formation hardness, excavate when motionless, to be higher or lower than the material that holds machine side again after then adopting quartering hammer with the hard rock fragmentation, and the material transport establishment of packing into unloaded to the tunnelling of rickyard machinery, tunnelling machinery is the engineering tunneling construction necessary equipments such as mine and tunnel.At present there is following problem in boom-type roadheader in the process of using: 1. can only be at formation hardness during greater than f8, can't carry out tunneling construction, can only adopt the mode of big gun pick, 2. work as formation hardness greater than the hard rock lane of f6 less than f8, tunneling construction is huge for the cutter tooth loss of heading machine cutting head, excavation cost is expensive, the driving progress is slow, 3. it is hard to work as rock, when soft error falls to distributing the tunnelling of geologic structure complexity, the big gun pick can only be carried out in f 〉=8,4. when running into coal seam or soft rock, because the development machine grounding pressure is excessive, machine is easy to depression, 5. boom-type roadheader climbing capacity≤16 are spent, when the inclined gallery gradient＞16 degree, development machine can't be worked, 6. the development machine construction can produce a large amount of dust, although atomization mechanism is arranged but effect is undesirable, air pollution is very serious in the tunnel, the constructor is for a long time in the underground work occupational disease-tuberculosis that is easy to get, therefore existing boom-type roadheader uses function ratio more single, applying working condition condition limitation is large, and applicability is not strong, can not satisfy the multiple requirement of constructing of different rock-layers mine laneway.
Summary of the invention
For the existing problem of boom-type roadheader in the above-mentioned prior art, the invention provides a kind of data mining duty that not only has, also has crushing function, and also have cutting function, and bucket and milling head can switch fast, and quartering hammer and bucket or milling head can be worked simultaneously, also can work independently, not only fragmentation and digging efficiency are high, and dependability is strong, durability is good, the broken digging type development machine of the multi-arm of long service life.
The technical scheme of clothes that the technical problem to be solved in the present invention is adopted is: the broken digging type development machine of described multi-arm comprises frame, walking mechanism, transport establishment, hydraulic system, electric system, operation steering device and digging mechanism, described digging mechanism links to each other with frame by linkage, described digging mechanism comprises bucket, bucket cylinder, chain frame; forearm; oil cylinder of small arm; big arm cylinder; large arm seat; large arm and angling cylinder; be respectively arranged with crushing mechanism on two tops of digging mechanism; described crushing mechanism links to each other with frame by linkage; described crushing mechanism comprises quartering hammer; the quartering hammer oil cylinder; chain frame; forearm; oil cylinder of small arm; big arm cylinder; large arm seat; large arm and angling cylinder, described linkage is double-deck pin shaft structure.
The present invention is owing to digging mechanism two side positions at development machine are fitted with respectively crushing mechanism, and is furnished with hydraulic quick coupler at digging mechanism, therefore when tunneling construction, according to the drift section size, select the single armed multi-arm, then the multi-arm while directly takes or mills and dig when rock stratum hardness is lower than f2, when rock stratum hardness be higher than f2 be lower than f5 then multi-arm enable simultaneously quick milling head and directly mill and dig, when formation hardness be higher than f5 then arm adopt bucket to take, other arms are enabled the quartering hammer fragmentation, as run in the material when occurring projection danger piece on ratchel and the tunnel, can start crushing mechanism and first oversize rock material be carried out fragmentation fast, or tunnel projection danger stone is carried out fragmentation fast get rid of the danger, greatly shortened employing hand breaking oversize rock material and processed on the tunnel and protruded the danger stone time, solved the difficult problem that present development machine can't be constructed in the tunnel greater than 16 degree at the above formation hardness of f8 and the gradient, greatly reduce the dust that construction produces, both alleviated labour intensity, reduced labor hour, reduce the tunneling construction cost, improved the safety work coefficient.Dependability of the present invention is high, durability is good, easy to operate, and applicability is strong, and long service life is widely used in the mine laneway tunneling construction and uses.
The present invention is fitted with crushing mechanism at digging mechanism two side positions, make the digging type development machine accomplish a tractor serves several purposes, having solved development machine can't adapt to formation hardness and look forward to the technical problem that solves greater than working condition, the tunnelling construction industry of f8 always in tunnelling work, obtain good efficiency of construction and safety production technique effect, filled up a technological gap on the rock speedy drivage history.
