Description
Technical field
The invention belongs to mining machinery technical field, particularly relate to a kind of large aperture construction raise boring machine, have
Can be suitable for the ability of various geotechnical boring, especially hard rock geological conditions, automaticity is high, and work efficiency is high.
Background technology
Raise boring machine, as important construction machinery a kind of in mining machinery, has been widely used in mine construction
Various sinking and driftings, it is mainly by the driven by motor hydraulic oil pump of rig, and utilizes hydraulic power by moment of torsion
Pass to drilling system with thrust, drive drilling rod and bit.Hobboing cutter on guide hole drill bit or reaming bit exists
Under the effect of thrust, do scroll-diced rock along bottom rock work surface and gradually form pit shaft.
In underground construction, raise boring machine is owing to being limited by working environment, operation geology, especially on hard rock ground
Large-diameter borehole to be realized in the case of matter, except ensureing reliability and degree of accuracy, moment of torsion and the axle simultaneously of rig
Thrust is also the key factor needing to consider.Current domestic mine is along with progressively turning to deep mining, pit shaft
Design mostly the most all directions, large aperture towards three meters of diameter above are developed, but domestic current courtyard construction equipment exists
The development of this aspect exists the most not enough, and level of development also lags far behind abroad, in the case of major part hard rock only
Small-bore can be used.
It addition, the length that raise boring machine is in the non-cutting time of work progress connecting and disconnecting drill rod has influence on the fast of working performance
Slowly.During connecting and disconnecting drill rod, needing to block drilling rod before releasing, the most domestic used kelly mode is main
There are two kinds: (1) is the most snap-in: this kelly mode needs special paraprofessional personnel to take plate insertion, labor in one's arms on side
Fatigue resistance is big, poor stability, it is impossible to realize one man operation's operation；(2) hydraulic jack promotes plate static directly
Snapping in, this kelly mode is fixed owing to snapping in direction, and needs are put in drilling rod card orientation and plate aligns, once-through operation
It is difficult to be adjusted in place, there will be the most just to operating unskilled operator, the phenomenon that plate can not block into.
Both the above mode has had a strong impact on connecting and disconnecting drill rod speed and then has had influence on courtyard construction operation efficiency.
A kind of rat hole drilling tool clamping device disclosed in the patent No. 201420535798.5, including hydraulic means, institute
State hydraulic means to be made up of hydraulic cylinder, hydraulic stem and oil pipe, also include that sleeve, binding clip, described sleeve upper end set
Having anchor ring, described sleeve lower end to be provided with ring flange, described ring flange external diameter is more than described anchor ring external diameter, institute

The direction of linear motion of plate 6-2, lower plugboard 6-2 snaps in the card side of drilling rod under the effect of plate oil cylinder 6-1
Position.After lower plugboard 6-2 snaps in drilling rod, due to the rotary torque pulling force more than back-moving spring 6-7, lower plugboard
6-2 and lower plugboard box 6-3 together does clockwise rotation along with the rotation of drilling rod, until lower plugboard box 6-3
Meet right block 6-4 to stop.In rotary course, lower plugboard 6-2 is in the slot direction along lower plugboard box 6-3
Still can be freely-movable, it is ensured that lower plugboard 6-2's is fully-inserted.When lower plugboard 6-2 extracts out, lower plugboard
Box 6-3 and lower plugboard 6-2 automatically resets under the effect of back-moving spring 6-7, until lower plugboard box 6-3 encounters
Left block 6-5, lower plugboard 6-2 encounter positive stop 6-6 reseting movement and stop.
The dynamic flashboard mechanism 6 of the present invention, it is achieved that automatization lower plugboard 6-2 kelly operation, operator without
The operation of rig inner space need to be entered, improve safety, reduce hand labor intensity, it is not necessary to direct bearing,
Reduce the operation requirement to operator, convenient, efficient, and achieve single unit behaviour truly
Make, substantially reduce the non-cutting time of connecting and disconnecting drill rod, improve the working performance of raise boring machine and courtyard equipment
Automatization level.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, described in above-described embodiment and description
The principle that the present invention is simply described, the present invention also has respectively without departing from the spirit and scope of the present invention
Planting changes and improvements, these changes and improvements both fall within scope of the claimed invention.Application claims is protected
Scope of protecting is defined by appending claims and equivalent thereof.
