With the ability of various geotechnical borings, especially hard rock geological conditions, automaticity height, operating efficiency height.
Background technology
Raise boring machine has been widely used in the various of mine construction as a kind of important construction machinery in mining machinery
Sinking and drifting, it is mainly by the motor belt motor hydrodynamic pressure oil pump of rig, and passed to moment of torsion and thrust using hydraulic power
Drilling system, drives drilling rod and bit.Hobboing cutter on guide hole drill bit or reaming bit is in the presence of thrust, along shaft bottom rock
Stone working face does scroll-diced rock and gradually forms pit shaft.
In underground construction, raise boring machine by operating environment, operation geology due to being limited, special feelings in hard rock geology
Large-diameter borehole is realized under condition, reliability and accuracy except ensureing rig are examined while moment of torsion and axle thrust are also needs
The key factor considered.Country mine is with deep mining is progressively turned at present, and pit shaft design is mostly all towards more than three meters
The large aperture direction of diameter is developed, but domestic current courtyard construction equipment has obvious not enough, development in the development of this aspect
Level is also far behind external, and small-bore can only be used in the case of most of hard rock.
In addition, length of the raise boring machine in the non-cutting time of work progress connecting and disconnecting drill rod has influence on the speed of operating efficiency.
During connecting and disconnecting drill rod, need to block drilling rod before releasing, the kelly mode that the country is used at present mainly there are two kinds：(1) people
Work is snap-in：The kelly mode needs special support staff to take plate insertion in one's arms on side, and labor intensity is big, and security is poor, it is impossible to
Realize one man operation's operation；(2) hydraulic jack promotes plate static state to be directly caught in, and the kelly mode is fixed due to being caught in direction,
Needs are put in drilling rod card orientation and plate is aligned, and once-through operation is difficult to be adjusted in place, to operating unskilled operating personnel to occur
To not just, the phenomenon that plate can not be sticked 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, the hydraulic pressure

Spring 6-7 pulling force, lower plugboard 6-2 and lower plugboard box 6-3 together do clockwise rotation with the rotation of drilling rod, until underthrust
Plate box 6-3 meets right block 6-4 and stopped.In rotary course, lower plugboard 6-2 in the slot direction along lower plugboard box 6-3 still
Can be with free movement, it is ensured that lower plugboard 6-2's is fully-inserted.When lower plugboard 6-2 is extracted out, lower plugboard box 6-3 and lower plugboard 6-2
Automatically reset in the presence of back-moving spring 6-7, until lower plugboard box 6-3 meets left block 6-5, lower plugboard 6-2 encounters spacing
Block 6-6 reseting movements stop.
The dynamic flashboard mechanism 6 of the present invention, realizes the lower plugboard 6-2 kellies operation of automation, and operator need not enter
Rig inner space is operated, and is improved security, is reduced hand labor intensity, without to direct bearing, reducing to operator
Operation requirement, it is convenient, efficiently, and realize single single-set operation truly, substantially reduce connecting and disconnecting drill rod
Non-cutting time, improve the operating efficiency of raise boring machine and the automatization level of courtyard equipment.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent is defined.
