A full-hydraulic crawler tunnel boring machine

Abstract

The utility model relates to a gallery drilling technology field especially relates to a caterpillar full hydraulic gallery drilling machine, including the bearing platform and the caterpillar assembly of installation in the bottom of bearing platform, the top of bearing platform rotatory installation has the slewing ring, the top of slewing ring fixedly has the support frame, the top of support frame is hinged with the bracket body, the top of bracket body is provided with the mast of carrying drilling assembly, still be installed on the bearing platform and drive the lifting mechanism of bracket body along the hinge upwardly overturn to adjust the mast pitch angle, the drilling assembly includes the power head, the power head adopts the speed change mechanism of double gear and sliding double gear combination, has realized two gear mechanical speed change, has effectively prolonged the equipment life and reduced the energy consumption, through the combination of slewing arm and hydraulic outrigger, has realized the flexible, active adjustment of support span, makes the drilling machine to need integral movement to be able to select the best support position for outrigger, effectively avoids the obstruction and rugged point in the gallery.
