Bionic micro pore diameter drilling and counterboring type underground tunneling device supporting and propulsion mechanism

Abstract

The invention relates to a bionic micro pore diameter drilling and counterboring type underground tunneling device supporting and propulsion mechanism which comprises a tail casing, a direct-current speed reduction motor, supporting claws and a supporting claw drive unit, wherein the tail casing is internally provided with the direct-current speed reduction motor; the supporting claw drive unit comprises a crown gear, symmetric spur gears, a first double-crank cam mechanism and a second double-crank cam mechanism; the direct-current speed reduction motor drives the crown gear; the crown gear is engaged with the symmetric spur gears at the same time; and the symmetric spur gears drive the first double-crank cam mechanism and the second double-crank cam mechanism separately so as to drive the two supporting claws. The bionic micro pore diameter drilling and counterboring type underground tunneling device supporting and propulsion mechanism is scientific and reasonable in structure design, realizes independent propulsion without external power equipment and is adapted to efficient propulsion of a micro pore diameter tunneling device.

Description

technical field [0001] The invention belongs to the field of bionic tunneling devices, in particular to a bionic micro-aperture drilling expansion type underground tunneling device supporting propulsion mechanism. Background technique [0002] With the acceleration of urbanization in our country, the three-dimensionalization of urban transportation and communication networks has become an important development direction of urban construction today. Small-scale construction such as the laying of small-diameter pipelines in urban construction, various geological exploration and research, and concealed illegal activities in anti-terrorism Excavation operations require corresponding underground excavation devices and equipment. The construction of large-scale pipelines such as subway tunnels in urban construction mainly uses shield machines. The system is complex, integrating drilling, transportation, and support, and the cost is relatively high. For the construction of small d...

[0005] Chinese invention patent (CN201710445841.7) discloses an underwater arching mud robot imitating earthworms, which includes two steering and support mechanisms. The conical arching mud head rotates, and the reciprocating movement of the arching mud head mechanism is driven by the expansion and contraction of the cylinder rod to realize drilling, but the movement form of the robot is complicated and the movement distance is limited

[0006] To sum up, current research or inventions mainly focus on three aspects. One is to use the common shield machine and the commonly used trenchless method, which cannot realize the trenchless with small aperture, and needs to dig a working well in advance. ; One is to improve the drilling expansion tool on the existing drilling rig to realize the drilling expansion movement, but the drilling expansion requires auxiliary equipment and power equipment on the ground, which cannot realize long-distance movement; the other is based on the bionic design method, in the original impact spear Or the impact sleeve is improved on the basis of adding walking, steering or control functions to achieve flexible movement

[0007] In particular, the structure of the propulsion mechanism of the existing tunneling device is complex and requires external equipment to propel

At present, there is no propulsion equipment that does not require external power equipment, can realize independent propulsion, and is suitable for small-diameter tunneling devices
