Abstract
The utility model relates to an engineering driving machinery man. The utility model is characterized in that the engineering driving machinery jointly uses a common drilling rig and a saw tooth cutter. The saw tooth cutter contains a saw blade type cutter used for cutting wood and a novelsaw tooth circular disk cutter. While in work, the common drilling rig first drills holes on a rock formation, and then the saw tooth cutter forwards cuts a rock mass along the drilled holes. The cut cutting surfaces are respectively crossed (including the cross with the exterior surface of mountain rocks) to get the practical space required by design.
Description
The utility model belongs to technical field of engineering machinery.Be a kind ofly to be used for all kinds of practical spaces such as tunnel, open channel (groove), culvert, cutting, half tunnel (hangar tunnel), cavern dwelling house, air raid shelter and pavement of road and plane excavation, and be particularly suitable for the road heading machinery and the mining machinery of in hard complete rock stratum, constructing.
At present, the method for tunnel construction mainly contains drilling and blasting method, three kinds of shield method and tunnel boring machine methods.Wherein, be tens of on the hob plate by its development machine head hobboing cutter is close to the work plane rock mass and it is applied powerful pressure and scissors comes crushed rock progressively to push ahead during the operation of tunnel boring machine method.The shortcoming of this development machine maximum that this method is at present used is that the cutter loss is big, and the energy of waste is many; Specificity is too strong, can not adapt to the tunnel section of difformity different size; Driving speed is slow, maintenance difficult; Body is huge, and assembling is complicated; Efficiency of construction is low.
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned existence, has replaced existing with the fragmentation of development machine hobboing cutter to rock mass with sawtooth disk and saw blade for the cutting of work plane rock mass.
The utility model technical solution:
Sawtooth development machine, its feature mainly are the uses of uniting of rig and saw cut machine.Wherein, the saw cut machine comprises and structurally duplicating in two kinds of the saw-blade type cutting machine that is usually used in lumbering and novel sawtooth disc cutters.The latter, its sawtooth disk vertically is hinged in an end of the tubular shaft type motor hollow bloster of motor (or include) in its center of circle by a gear pivot pin; And this disk is parallel to the vertical section of this motor (or this bloster).Turn under the transmission of travelling gear in tubular shaft type motor (or the motor in the hollow bloster) drive and its free end, the sawtooth disk can rotate.
During operation, the utility model is earlier to the work plane rock body drilled, and its bore direction can level, vertical or tilt.After taking out drilling core, the sawtooth disk of saw cut machine will rotate at a high speed when tubular shaft type motor (or hollow bloster) stretches in boring and advance jointly with cutting rock mass (and when the utility model adopts the operation of saw-blade type cutting machine, its saw blade will directly stretch into and cut the rock stratum in the boring).When formed cut surface intersects (comprise with mountain rock external surface and intersecting) successively, can get column that an end face and each side break away from rock stratum on every side or terrace with edge shape rock mass (comprise by single cut surface directly cut irregular rock mass).The root of this rock mass fractures.Then, whole to take out of promptly get aforementioned required practical space part or all of with it.
Advantage of the present utility model:
Since needn't the whole rock mass of hand breaking during operation, the carbide alloy that the sawtooth development machine consumes and the energy are all seldom.Assembling is fast with maintenance, the driving speed height.Operational sequences such as its ventilation, depositing dust, " muck removal " prevent that with waterproof the processing of engineering geological problems such as gas is also relative easy.The hole wall is smooth smooth, and it is minimum to surpass, owe the amount of digging, and saves lining material.In addition, it is little to rock stratum disturbance on every side to construct, and operates saferly, saves more labour.
Fig. 1 is cutting machine saw blade of the present utility model, sawtooth disk and tubular shaft type motor (or hollow bloster) schematic diagram.
Fig. 2 is the five class work plane schematic diagrames that the utility model operation is met often.
Fig. 3 is the basic morpheme schematic diagram of the resulting general column rock mass in the utility model cutting rock stratum before and after taking out.
Below in conjunction with accompanying drawing the utility model is further described:
1 is the saw blade of saw cut machine among Fig. 1.The 2nd, the tubular shaft type motor of saw cut machine (or hollow bloster), the length of its section (or cross section) major axis is about about in the of 20 centimetres.By gear pivot pin 3, the sawtooth disk 4 of cutting machine is hinged on this motor (or this beam).
All continuous circular line are boring boundary lines as 5 indications among Fig. 2; All dotted lines are the line of cut or the cutting seam (referring to Fig. 3) of saw blade and sawtooth disk as 6 indications.When tubular shaft type motor (or hollow bloster) stretches in the boring of boring boundary line 5, the same rock stratum of cutting of sawtooth disk 4 with saw blade, and form cut surface.These faces can surround the roughly rock mass of the column shown in shade among Fig. 2, terrace with edge shape or other respective shapes of section configuration after intersecting (comprise with mountain rock external surface 10 and intersecting) successively.
Among Fig. 37 cut when being the utility model operation general column rock mass; The 8th, the root of this rock mass; The 9th, the arch groove that boring stays on rock pillar.
Claims (2)
1, sawtooth development machine, mainly form by rig and two parts of saw cut machine, it is characterized in that saw cut machine part is made up of the sawtooth disc cutter, its sawtooth disk is parallel to the vertical section of tubular shaft type motor, and by turning to travelling gear to rotate by this motor drives.
2, sawtooth development machine according to claim 1 is characterized in that saw cut machine part also can be the saw-blade type cutting machine.
