Technical field
The utility model relates to the heading equipment field, is specially the broken rock device that a kind of constructing tunnel or tunnelling are used.
Background technology
In China tunnel, tunnel and underground engineering construction, middle hard rock construction accounts for significant proportion, and drilling and blasting method and comprehensive drivage method are two kinds of job practicess commonly used that hard rock tunnel and tunnel are dug.Yet low, the poor stability of drilling and blasting method bore operation efficient, misoperation causes gas explosion easily, and the roadway forming quality also is difficult to control, and backbreaking, it is serious to owe to dig.Comprehensively than higher, formation hardness can not surpass f8 to drivage method to the requirement in tunnel, and head-room must not be less than 3.0 meters, and width must not be less than 4 meters.If local formation hardness is too high, also need employing to loosen moving big gun and assist driving, can not fundamentally stop to blow out.
Quartering hammer especially hydraulic breaking hammer has characteristics such as ballistic work is big, frequency of impact height, and it passes to hard rock with the form of shock wave with ballistic work by drill steel, can be in moment the compressive strength considerably beyond rock, thereby realize fragmentation to hard rock.At present quartering hammer just develops towards directions such as super large percussion power, intellectuality, variations, carries out constructing tunnel and tunnelling is a kind of effective means with it.But how it effectively is installed on the equipment, and realizes that broken rock driving is the problem that we need solution badly.
The utility model content
In order to overcome the deficiency of drilling and blasting method and comprehensive drivage method, the purpose that realization is carried out constructing tunnel and tunnelling with quartering hammer, the broken rock device that the utility model provides a kind of constructing tunnel or tunnelling to use.Adopt and to break the rock device, do not need to blow out to realize quick, the efficient driving in superhard total rock tunnel, avoided the generation of major accident from root.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of broken rock device, this device are provided with panoramic table, broken rock arm and quartering hammer, and an end of broken rock arm connects panoramic table, and the other end of broken rock arm connects quartering hammer.
Described broken rock device, panoramic table is installed on the carrier by pivoting support.
Described broken rock device, broken rock arm is a telescopic arm structure.
Described broken rock device, broken rock arm is for breaking the telescopic arm structure that the flexible outer arm of flexible inner arm of rock arm and broken rock arm connects and composes.
Described broken rock device, the outer end and the panoramic table of the flexible outer arm of broken rock arm are hinged.
Described broken rock device also comprises the hydraulic cylinder I, and an end of hydraulic cylinder I is articulated on the panoramic table, and the other end of hydraulic cylinder I is articulated in brokenly on the flexible outer arm of rock arm.
Described broken rock device, the end and the quartering hammer of the flexible inner arm of broken rock arm are hinged.
Described broken rock device also comprises the hydraulic cylinder II, and an end of hydraulic cylinder II is articulated in brokenly on the flexible inner arm of rock arm, and the other end of hydraulic cylinder II is articulated on the quartering hammer.
The beneficial effects of the utility model are:
1, in order to satisfy the construction in different size tunnel or tunnel, broken rock arm adopts telescopic arm structure, stretches between the interior outer arm by Driven by Hydraulic Cylinder.
2, the end and the quartering hammer of the flexible inner arm of the broken rock arm of the utility model are hinged, utilize hydraulic cylinder can realize the broken thrum degree that quartering hammer is different.
3, the outer end and the panoramic table of the flexible outer arm of the broken rock arm of the utility model are hinged, utilize lifting hydraulic cylinder can realize brokenly the pitching of rock arm in the carrier vertical direction.
4, the utility model panoramic table utilizes pivoting support to link to each other with carrier, utilizes hydraulic cylinder or hydraulic motor can realize brokenly the deflection of rock arm in the carrier horizontal direction.
5, the utility model need not to blow out to realize the fast, efficient, safe driving in superhard total rock lane as the new tool of constructing tunnel and broken rock driving.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1 panoramic table; The flexible outer arm of 2 broken rock arms; The flexible inner arm of 3 broken rock arms; 4 quartering hammers; 5 hydraulic cylinder I; 6 hydraulic cylinder II; 7 drill steels.
The specific embodiment
As shown in Figure 1, the broken rock device of the utility model mainly comprises panoramic table 1, broken rock arm (the flexible outer arm 2 of broken rock arm, the flexible inner arm 3 of broken rock arm) and quartering hammer 4, and an end of broken rock arm connects panoramic table 1, and the other end of broken rock arm connects quartering hammer 4.Panoramic table 1 is installed on the carrier by pivoting support, and panoramic table 1 can be realized the deflection of wraparound rotating shaft by hydraulic cylinder or fluid motor-driven; Broken rock arm is a telescopic arm structure, realizes the flexible of broken rock arm by Driven by Hydraulic Cylinder.In the present embodiment, broken rock arm is broken the telescopic arm structure that flexible inner arm 3 of rock arm and the flexible outer arm 2 of broken rock arm connect and compose, the outer end and the panoramic table 1 of the flexible outer arm 2 of broken rock arm are hinged, one end of hydraulic cylinder I 5 is articulated on the panoramic table 1, the other end of hydraulic cylinder I 5 is articulated in brokenly on the flexible outer arm 2 of rock arm, in the pitching that can realize under the promotion of hydraulic cylinder I 5 on the equipment vertical direction; End and the quartering hammer 4 of the flexible inner arm 3 of broken rock arm are hinged, and an end of hydraulic cylinder II 6 is articulated in brokenly the rock arm and stretches on the inner arm 3, and the other end of hydraulic cylinder II 6 is articulated on the quartering hammer 4, but under the promotion of hydraulic cylinder II 6 angle of attack of flexible modulation quartering hammer 4.In addition, quartering hammer 4 is furnished with drill steel 7.
In the utility model, the typical operation process of broken rock device is as follows:
Before the broken rock operation, at first drive broken rock arm by the flexible outer arm 2 of broken rock arm and deflect into the operating position by panoramic table 1; Then, stretch out brokenly the flexible inner arm 3 of rock arm, the drill steel end of quartering hammer 4 is compressed treat fragmented rock, finished breaking is finished in last quartering hammer 4 work.If the lower rock in broken broken rock arm position relatively then needs to change the impact direction of quartering hammer 4 by regulating brokenly the end hydraulic cylinder of the flexible outer arm 3 of rock arm.
