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 through the rotation cutting of cutterhead.
But the inventor finds that there is the deficiency of the following aspects in existing development machine in the process of embodiment 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, and 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, work can't be carried out with the pick parcel.
Two, because in the digging process of inclined shaft coal mine roadway; Development machine is main with digging coal petrography, half coal petrography or rock gangway mainly; 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.The rock that present stone head development machine is primarily aimed at below the individual event compressive strength 100Mpa designs; Because the down-hole geological condition is complicated; Development machine often runs into the rock of individual event compressive strength greater than 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 in tunneling process, running into the bigger rock of hardness, generally the mode through 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 make development machine, after explosion finishes, again development machine retracted and worked on away from work plane (generally need make development machine retreat about 30 meters to 50 meters).But existing development machine is bulky, and relevant device is more complicated, when development machine moves; Also need to move with its associated device thereupon; Special in the bigger inclined gallery of the gradient, huge work system shifts comparatively difficulty, thereby has increased job costs virtually.Like " 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 in blasting process, to make equipment " not away from ", 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 accomplish multi-function operation; Material to driving mechanical shovel prelaminar part and left and right side needs artificial auxiliary feeding to conveying mechanism, and manual work is slower, often causes the colliery to be deposited in the left and right sides leading flank of shovel prelaminar part 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 accomplishing the tunnel cut; The surperficial danger in the end face in tunnel and left and right side is a lot, planeness is not enough, needs manual work to accomplish danger and removes and flat surface, just can carry out next step supporting operation; Since these auxiliary charging personnel with 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, and artificial in addition operating efficiency is low, has reduced tunnelling speed; Have a strong impact on Coal Production and benefit, even jeopardize workman's life security.
