Description
Technical field
The utility model is related to engineering machinery, and in particular to a kind of rock drilling device realized two-stage and promoted.
Background technology
It is needed in water power tunnel, subway engineering, railway tunnel, vcehicular tunnel, underground power house, military ground engineering construction
Preliminary bracing is carried out, needs to carry out drilling operation by rock drill in Bracing Process（Such as lock foot anchoring stock hole, advanced tubule
Hole）.Due to above-mentioned operating environment narrow space, drilling operation is manually presently mainly carried out by pusher leg drill.
As shown in Figure 1, the drilling rod stroke of rock drilling device provisioned in heavy construction equipment is all pushed away by rock drill is opposite at present
It moves and generates into beam, thus the length dimension of forward beam is very big, is put to good use not open in narrow working environment, it is difficult to it is competent at above-mentioned work
Make.
Utility model content
Technical problem to be solved in the utility model can be met narrow in view of the shortcomings of the prior art, offer is a kind of
The engineering machinery rock drilling device of job space.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of rock drilling realized two-stage and promoted
Device, including rock drill, upper guide plate, propelling cylinder, forward beam, compensating cylinder, lower guide plate, wherein
The rock drill connects composition first movement pair by the top of upper guide plate and forward beam, the propelling cylinder
One end is connect with forward beam, and the other end is connect by wire rope pulley mechanism with rock drill；
The lower part of the forward beam connect with rack by lower guide plate composition the second prismatic pair, one end of compensating cylinder with
Rack connects, and the other end is connect with forward beam.
The utility model is using cumulative principle, and the displacement using rock drill with respect to forward beam is as a hemistich of rock drilling device
Journey, other half stroke of the forward beam with respect to the displacement of rack as rock drilling device.Rock drilling device entire in this way is in identical work
In the case of stroke the length dimension of forward beam by be conventional apparatus half, rock drilling device can be met in operation in narrow space
It needs.
To improve the job stability of the utility model rock drilling device drilling rod, the front end setting of the rack is bored for buttressing
The puncheon centralizing device of bar front end.When rock drill at work, the puncheon centralizing device in rock drill distal end will buttress drilling rod, prevent drilling rod from shaking,
Improve borehole stability.
To improve the job stability of the utility model rock drilling device, the front end of the rack is provided with positional cylinder, fixed
The extensible member front end of position oil cylinder is provided with the locating rod for supporting working face.After rock drilling device determines punch position,
Locating rod is acted by positional cylinder stretches out, until on its top to working face.Rock drilling device can be effectively reduced in this way in work
Shaking during work improves borehole stability.
The upper and lower guide plate is preferably the guide plate that cross section is V-type, the company of the forward beam and upper and lower guide plate
End is connect to be set as and the matched convex body of V-type guide plate.In this way, the connection of the utility model forward beam and rock drill, rack
It is more reliable, it is advantageous steady mobile.

Bar 10, puncheon centralizing device 11, wherein upper guide plate 2, lower guide plate 7 are preferably the guide plate that cross section is V-type.
Rock drill 1 is connect by upper guide plate 2 with forward beam 5, and first movement pair is formed.One end of propelling cylinder 4 with push away
It is connected into beam 5, the other end of propelling cylinder 4 is connect by wire rope pulley mechanism with rock drill 1.When propelling cylinder 4 works
Rock drill 1 will be acted on by wire rope pulley mechanism, realizes relative motion of the rock drill 1 with respect to forward beam 5, to realize this
The half stroke of utility model rock drilling device.
Forward beam 5 is connect by lower guide plate 7 with rack 8, and the second prismatic pair is formed.6 one end of compensating cylinder connects with rack 8
It connects, other end is connect with forward beam 5.Forward beam 5 will be pushed to be moved with respect to rack 8 when compensating cylinder 6 works, to realize this
Another half trip of utility model rock drilling device.
Puncheon centralizing device 11 is arranged in the front end of rack 8, for buttressing 3 front end of drilling rod.3 tail end of drilling rod is connect with rock drill 1.
