Background technique
Drill jumbo has become one of commonly used equipment in method of tunnel drilling and blasting mechanized construction, but bores tunnel perimeter blasthole
When, drilling rod cannot be pasted to the incision of tunnel contour line level, needed with certain heterodyne angular bit to designated position, it affects tunnel
The size of profile out break, the smoother degree of tunnel contour and the extent of damage to tunnel contour peripheral rock, serious damage
The safety that extreme influence tunnel is constructed for a long time and construction cost.
Current drill jumbo be it is linear punching, it is dry due to equipment various in tunnel in drilling tunnel perimeter
It relates to or the limitation of construction space, causes the drill steel of existing drill jumbo to be pierced in tunnel perimeter dike at an angle, nothing
Method is constructed by technique requirement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of forward beam assembly of tunnel perimeter blasthole drilling.
A kind of forward beam assembly of tunnel perimeter blasthole drilling, including forward beam, are equipped with rock drilling in the forward beam rear end
Drilling machine, the drill steel of rock drilling machine extend to the front end of the forward beam from the rear end of the forward beam, it is characterised in that: described
The front end of forward beam is fixedly installed with retractable guide sleeve, is installed with fixed guide sleeve in the forward end of the forward beam, pushes away described
Movable guide bush, the retractable guide sleeve, fixed guide sleeve are slidably fitted on into beam between the fixed guide sleeve and rock drilling machine
With the equal loop of movable guide bush on the drill steel.
Further are as follows: the retractable guide sleeve includes driving mechanism, telescopic rod and guide sleeve, and described telescopic rod one end is led with described
Set is fixedly connected, and the other end of the telescopic rod is connect with the driving mechanism, and the driving mechanism is installed in the forward beam
On.
Further are as follows: the driving mechanism is hydraulic gear or is mechanical spiral transmission mechanism.
Further are as follows: inner sleeve is equipped between the retractable guide sleeve and fixed guide sleeve and the drill steel, in the inner sleeve
Loop is enclosed on the drill steel, the outer ring rotating of the inner sleeve is mounted on the retractable guide sleeve or fixed guide sleeve.
Beneficial effects of the present invention: retractable guide sleeve is set in the front end of forward beam and is arranged admittedly in the forward end of forward beam

The size for enough controlling tunnel contour out break, ensures the smoother degree of tunnel contour, reduces the damage to tunnel contour peripheral rock
Degree.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the partial structural diagram of present invention Construction State in tunnel.
In figure, 1, rock drilling machine；2, movable guide bush；3, fixed guide sleeve；4, retractable guide sleeve；5, forward beam；6, drill steel；7, tunnel
Road palisades.
Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.It should be noted that left, center, right in present example,
The positional terms such as upper and lower are only relative concepts or be to refer to, and should not be considered as with the normal operating condition of product each other
It is restrictive.
As shown in Figure 1, a kind of forward beam assembly of tunnel perimeter blasthole drilling, including forward beam 5, in the forward beam 5
Rear end is equipped with rock drilling machine 1, and the drill steel 6 that the rock drilling machine 1 is arranged is arranged along the forward beam 5, before the forward beam 5
End is fixedly installed with retractable guide sleeve 4, fixed guide sleeve 3 is installed in the forward end of the forward beam 5, on the forward beam 5
Movable guide bush 2, the retractable guide sleeve 4, fixed 3 and of guide sleeve are slidably fitted between the fixed guide sleeve 3 and rock drilling machine 1
The equal loop of movable guide bush 2 is on the drill steel 6；The retractable guide sleeve 4 includes driving mechanism, telescopic rod and guide sleeve, described flexible
Bar one end is fixedly connected with the guide sleeve, and the other end of the telescopic rod is connect with the driving mechanism, and the driving mechanism is solid
It is located on the forward beam 5；The driving mechanism is hydraulic gear or is mechanical spiral transmission mechanism；
It is equipped with inner sleeve between the retractable guide sleeve and fixed guide sleeve and the drill steel, the inner sleeve inner ring loop is in the pricker
On bar, the outer ring rotating of the inner sleeve is mounted on the retractable guide sleeve or fixed guide sleeve；The outer ring of the inner sleeve is outer arc
The position that the inner sleeve is corresponded on shape periphery, the retractable guide sleeve and fixed guide sleeve is equipped with the inner arc to match with inner sleeve outer ring
Connected in star, the inner sleeve are rotatably installed in described flexible by rotation relation of the outer arcuate periphery after chimeric with inner arc connected in star
On guide sleeve or fixed guide sleeve.
The working principle of the invention: rock drilling machine is moved along forward beam from rear end forward end, while generates drill steel palisades
Percussion, the schematic diagram of the operation on tunnel palisades 7 of drill steel 6 as shown in Figure 2, retractable guide sleeve 4 can pull drill steel 6 to moving down
It is dynamic, make the drill steel bending at fixed guide sleeve 3 of drill steel 6, the inner sleeve axis of rotation can be protected always with drill steel drill steel axis after bending
Hold consistent friction between reduction guide sleeve and drill steel 6；6 position of drill steel is relative to the angle before stretch bendingθ2, forward beam 5 promotes
Angle is relative to the angle of theoretical drill center lineθ1, drilling rod withθ =θ 1 - θ2 angle pierces.H1 is to bore after adjusting
Centerline hole Distance Theory drill center linear distance, H2 are to adjust preceding drill center linear distance theoretical drill center line distance, H1 <
H2.Therefore the extent of damage to tunnel contour peripheral rock can be effectively reduced in the present invention.
