Description
Technical field
The present invention relates to the extractive equipment technical field, relate in particular to a kind of tunneling machine cutting mechanism and development machine.
Background technology
Along with the fast development of China's economic construction, coal industry constantly develops towards the direction of mechanization, automation, and comprehensive mechanical coal mining equipment is applied among the coal production of various geological conditionss more and more widely.In the production operation of mechanized extraction coal, development machine is one of main extractive equipment, realizes the digging in tunnel by the rotation cutting of cutterhead.
But the inventor finds that there is the deficiency of the following aspects in existing development machine in implementing process of the present invention:
One, because development machine need have tunneling effect preferably to coal petrography, half coal petrography and rock gangway, this just restricts and causes the short and dense arrangement of pick of development machine, rotary speed is lower in addition, when when the development machine operation, running into clay or frozen soil layer, cutterhead is very easy to adhesive tape clay or frozen soil, thereby with the pick parcel, work can't be carried out.
Two, because in the digging process of inclined shaft coal mine roadway, development machine is mainly based on digging coal petrography, half coal petrography or rock gangway, the hardness of coal petrography and half coal petrography is lower, development machine can normally be dug usually, and the hardness of rock gangway is bigger, and development machine generally is merely able to the lower tunnel of digging formation hardness, economy ground.Present stone head development machine is primarily aimed at the following rock of individual event compressive strength 100Mpa and designs, because down-hole geological condition complexity, development machine often runs into individual event compressive strength greater than the rock of 100Mpa in tunneling process, if continue to adopt the development machine driving, not only use cost increases suddenly but also can reduce application life of equipment.Therefore, when running into the bigger rock of hardness in tunneling process, generally the mode by explosion realizes digging.But, in making the process that blows up with dynamite, have a lot of high speeds and collapse the rock fragment that, cause the development machine critical component to damage easily, therefore, usually in the operating mode that adopts the explosion driving, need to make development machine away from work plane (generally need make development machine retreat about 30 meters to 50 meters), after explosion finishes, again development machine is retracted and worked on.But existing development machine is bulky, and relevant device is more complicated, when development machine moves, equipment associated with it also needs to move thereupon, special in the bigger inclined gallery of the gradient, huge work system shifts comparatively difficulty, thereby has increased job costs virtually.As " a kind of development machine " (patent No.: CN201010224590.8), though development machine has been carried out self preservation to a certain degree, but also only be to make equipment " not away from " in blasting process, the equipment in the blasting process of fundamentally not solving still needs the problem of " moving ".
Three, existing development machine is bulky, inconvenience is used in digging at small-sized tunnel, adit or the thinner seam in colliery, many collieries are carried out big gun and are adopted in this operating mode, the danger that big gun is adopted is very high, and operating efficiency has had a strong impact on tunnelling speed and comprehensive digging speed.Existing development machine mainly contains two kinds of cantilevered and straight arm types.The cutterhead of boom-type roadheader is tight the connection with cutting arm, can't realize changing multiple functional device and finish multi-function operation, material anterior to the development machine shovel board and the left and right side needs artificial auxiliary feeding to conveying mechanism, manual work is slower, often cause the colliery to be deposited in the left and right sides leading flank of shovel board front portion and machine, can't satisfy the Capability Requirement of conveying mechanism, equipment efficiency of usage is not enough.And the development machine of straight arm type cutting arm device is after finishing the tunnel cut, the surperficial danger in the end face in tunnel and left and right side is a lot, planeness is not enough, need manually finish danger removes and flat surface, just can carry out next step supporting operation, because these auxiliary charging personnel and carry out the cleaning of tunnel end face and side and the non-supporting district that smooth personnel are in the tunnel, operating environment is abnormally dangerous, artificial in addition operating efficiency is low, reduced tunnelling speed, have a strong impact on Coal Production and benefit, even jeopardize workman's life security.
