The all-in-one cutterhead is dug in pick
Technical field
The present invention relates to a kind of pick and dig the all-in-one cutterhead, be particularly useful for the excavation in gutter under the coal mine, the finishing of tunnel metope, the ditching in the ground surface works.
Background technology
Along with the development of coal mining technology and engineering machinery technology, China's coal-mine and mechanical engineering degree improve constantly, and use the kind of machinery and form more and more, but still can not satisfy the production demand.For example, the drift dewatering ditch is the important component part of drainage underground system under the coal mine, when the design tunnel, the gutter need be excavated in the both sides, tunnel, because the gutter is generally narrower and be lower than ground, tunnel, can't finish by development machine, again because this place is all ragstone, it is big that difficulty is dug in pick, mainly make it loosening at present by drilling and blasting after, carry out the hand excavation again.Simultaneously, the draining in the ground, pipeline, wiring installation also all need ditching, but ditch for soil structure ground usage mining machine, and for rock quality face or concrete surface, still need the hand excavation, and efficient is lower.This mode not only efficient is low, and is dangerous higher for the down-hole construction, had a strong impact on the construction speed and the safety of down-hole and ground surface works.Therefore, need a kind of digging machine structure of digging safely and efficiently in a hurry.
Summary of the invention
Technical problem: the objective of the invention is to overcome the weak point in the prior art, propose a kind of compact conformation, the all-in-one cutterhead is dug in time saving and energy saving, the down-hole high pick of construction safety efficient.
Technical scheme: the all-in-one cutterhead is dug in pick of the present invention, mainly is made of hydraulic motor, hydraulic motor fixed case, T generating gear reducer, runing rest and the cylinder that is furnished with a plurality of pick-shaped cutters; Wherein: hydraulic motor is located at the left side in the hydraulic motor fixed case, establish the bearing support of fixed hydraulic motor output shaft in the right-hand end of hydraulic motor fixed case, the right-hand end of hydraulic motor fixed case connects T generating gear reducer, and T generating gear reducer mainly is made of T generating gear reducer, the two ends splined shaft, power transmission shaft, bevel gear set and the straight-tooth wheels that are located in the T generating gear reducer; Bevel gear set is made of the bevel gear wheel that is located at the bevel pinion on the hydraulic motor output shaft and be located on the power transmission shaft respectively; The spur gear group is respectively by being located at the pinion on the power transmission shaft, the idler gear that is meshed with pinion and the gear wheel that is fixed on splined shaft middle part, two ends that is meshed with idler gear constitutes; Runing rest is two, and symmetry is located on the two ends splined shaft of T generating gear reducer two sides of tail, is respectively installed with the cylinder that is furnished with a plurality of pick-shaped cutters on two runing rests.
Described runing rest mainly is made of the swivel mount that is fixed on the fixed mount on the T generating gear reducer and be fixed on the splined shaft of two ends, has the groove that is fastened on the fixed mount on the swivel mount, is provided with a pair of radial thrust roller bearing between fixed mount and the swivel mount.
Beneficial effect: the present invention adopts fluid motor-driven, satisfy the convenience that downhole anti-explosion requirement and ground surface works use, gear reduction box adopts T shape structure to make the overall simple compactness, adopt powerful broken rock cylinder, it is strong to dig the ability of digging, give bevel gear set by hydraulic motor output shaft with power transmission, after the transmission of one-level awl tooth changes rotation direction, pinion by the straight-tooth wheels passes to the deceleration of idler gear realization one-level, give gear wheel with transmission of power again, pass to symmetrical runing rest by splined shaft at last, two runing rests respectively are with the cylinder of adorning pick-shaped cutter outward, by the broken rock of rotation realization cut of cylinder.Can dig the rock mass that digs broken hardness f<8, can satisfy down-hole and ditch, ground excavation demand, save labour's input, improve mechanization degree and safety that colliery and ground surface works are carried out.The present invention also can connect with down-hole raking loader or ground excavation machine by bearing pin, realizes that multiple pick digs function.Can carry out 90 ° of rotations of cutterhead according to ditching width demand.The pick in realization underworkings and ground surface works gutter is dug.Its compact conformation, installation and maintenance are simple, and the reliability height is safe and efficient, time saving and energy saving, have a practicality widely.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
The all-in-one cutterhead is dug in pick of the present invention, mainly is made of hydraulic motor 1, hydraulic motor fixed case 2, T generating gear reducer, runing rest 7, idler gear 8, power transmission shaft 9, bevel gear set 10, cylinder 11, pick-shaped cutter 12, hydraulic motor output shaft 13.Hydraulic motor 1 is located at the left side in the hydraulic motor fixed case 2, establish the bearing support 14 of fixed hydraulic motor output shaft 13 in the right-hand end of hydraulic motor fixed case 2, the right-hand end of hydraulic motor fixed case 2 connects T generating gear reducer, and T generating gear reducer mainly is made of T generating gear reducer 3, the two ends splined shaft 6, power transmission shaft 9, bevel gear set 10 and the straight-tooth wheels that are located in the T generating gear reducer 3; Bevel gear set 10 is made of the bevel gear wheel that is located at the bevel pinion on the hydraulic motor output shaft 13 and be located on the power transmission shaft 9 respectively, and big bevel pinion is meshed; The spur gear group is respectively by being located at the pinion 4 on the power transmission shaft 9, the idler gear 8 that is meshed with pinion 4 and the gear wheel 5 that is fixed on two ends splined shaft 6 middle parts that is meshed with idler gear 8 constitutes; Runing rest 7 is two, symmetry is located on the two ends splined shaft 6 of T generating gear reducer two sides of tail, runing rest 7 mainly is made of fixed mount 7-1 and swivel mount 7-4, fixed mount 7-1 is fixed on the T generating gear reducer 3 through I inner bolt 7-3, swivel mount 7-4 is fixed on the two ends splined shaft 6, have the groove that is fastened on the fixed mount 7-1 on the swivel mount 7-4, be provided with a pair of radial thrust roller bearing 7-2 between fixed mount 7-1 and the swivel mount 7-4.Be respectively installed with the cylinder 11 that is furnished with a plurality of pick-shaped cutters 12 on two runing rests 7, cylinder 11 is fixed on the swivel mount 7-4 through II inner bolt 7-5.The cylinder 11 that is furnished with a plurality of pick-shaped cutters 12 is identical with the structure of existing pick-shaped cutter.
