Description
Technical field
Mining and the road heading machinery used on a kind of middle and small scale coal mine scope of operation belong to the coal mine machinery field.
Background technology
The coal mine tunneling machine of producing both at home and abroad all is large-scale development machine at present, and weight is the 15-50 ton, can only adapt to large-scale Coal Production.Middle-size and small-size or vertical formula colliery for those because have that well head is little, short narrow, the restriction that the hanging device tonnage is little in tunnel, large-scale development machine can't be delivered on the scope of operation.And the road surface in the mine, channel condition abominable (loose as the road surface, ponding etc.), may make machine be absorbed in wherein and can't walk.
No. 2006200530653 utility model patent has proposed a kind of " mini-boom coal mine tunneling machine ", and this body amasss little, in light weight, as to be applicable to medium and small colliery mining, but following weak point is arranged:
1, the machine deadweight is too light, poor stability, and when running into the coal seam with certain degree of hardness, machine works is got up and will be swung or bob, can't normal operation.
2, because the cutting arm hoist cylinder that the support cutting arm moves up and down has only one, so the hoist cylinder live load is excessive, and easy deformation produces oil leakage phenomenon.Because support revolution fulcrum that cutting arm swings and be being connected of stomidium and axostylus axostyle behind the cutting arm, when angling cylinder swung cutting arm, the twisting resistance that axostylus axostyle is subjected to was very big, also easy deformation and can't operate as normal, in a word, fault rate is higher.
Summary of the invention
The purpose of this utility model provides a kind of modified coal mine tunneling machine, accomplishes deadweight rationally, good stability, and fault rate is low, is adapted to middle or small colliery excavation operation.
Technical scheme is that " mini-boom coal mine tunneling machine " improved.The utility model comprises the body that fire-proof motor and explosion-proof electrification control device, oil pump and hydraulic pressure control device are housed, and the body below has crawler type walking mechanism, front lower place to have loader mechanism, middle rear to have conveying mechanism, front upper place that the boom-type roadheader structure is arranged; The bit of described boring mechanism is affixed with the driving hydraulic motor of band reducer, the driving hydraulic motor is affixed with the telescopic oil cylinder telescopic arm that is positioned at the cutting arm inner chamber, improvements are that the body top is equipped with floating bearing and the rotary disk that is placed on the floating bearing, the front end of left and right cutting arm angling cylinder is hinged on respectively on the rotary disk upper surface left and right side, their rear end is hinged on respectively on the body left and right side, the rotary disk front side has left and right supporting arm respectively, and both sides, cutting arm rear end are hinged on respectively on the left and right supporting arm upper arm; The front end of left and right cutting arm hoist cylinder is hinged on respectively on the left and right side of cutting arm middle part, their rear end is hinged on respectively on the left and right supporting arm underarm, and driving hydraulic motor, angling cylinder, hoist cylinder and telescopic oil cylinder all have oil circuit to be communicated with hydraulic pressure control device.
The headwork principle is as follows: handle left and right cutting arm hoist cylinder, cutting arm is moved up and down; Handle left and right cutting arm angling cylinder, can make the rotary disk deflection of turning left or turn right, the left and right supporting arm of rotary disk front side then drives cutting arm and cutting arm hoist cylinder and turns left or turn right deflection; Manipulation is positioned at the telescopic oil cylinder of cutting arm inner chamber, and bit is moved forward and backward.Fire-proof motor in the power turn-on, body drives oil pump and produces hydraulic oil, and the pilot oil pressure control device makes the hydraulic motor rotation, orders about bit and rotates the cutting ore that advances.Bit is spiral heading end, be equipped with on it many carbide alloy pick, thereby can cut out the section of arbitrary shape.In cutting, the nozzle that is contained on the cutting arm sprays the vaporific globule, the effect of playing depositing dust and preventing to produce spark.Nozzle links to each other with the cooling water tank that is positioned at body by water pipe.In addition, the cutting arm sidepiece is equipped with explosion-proof wide-angle shot-light and gas detector.Explosion-proof wide-angle shot-light is used for illumination.Gas detector is used to measure gas density, sends signal to the explosion-proof electrification control device on the body when gas density exceeds standard, and realizes autostop.
Compared with the prior art, the utility model has following characteristics:
1, volume is little, deadweight 10-12 ton, and good stability adapts to medium and small or vertical coal uses.
Owing to increased rotary disk, floating bearing parts, overstriking cutting arm, change single cutting arm hoist cylinder into two cutting arm hoist cylinders, so the machine deadweight is increased to the 10-12 ton, thereby increased the stability of machine works.The supporting role of especially left and right two hoist cylinders gets much than the supporting ﹠ stablizing of single hoist cylinder.
2, fault rate is low.
Because the revolution fulcrum that the support cutting arm swings is a rotary disk, rotary disk places again on the floating bearing, and the torsional stress that left and right cutting arm angling cylinder makes cutting arm do generation when swinging has been dissolved by floating bearing, so fault rate reduces.Add two cutting arm hoist cylinders and replace single cutting arm hoist cylinder, promptly the live load of hoist cylinder does not reduce half, thereby yielding and fault such as leakage of oil occurs yet.
