Abstract

The invention relates to a folding boring tower which comprises a boring tower support arranged on the rear part of a rig substructure and a tower body articulated on the boring tower support, wherein a tower body comprises an upper section boring tower, a lower section boring tower and a tower rising oil cylinder, and the tower rising oil cylinder is arranged between the lower section boring tower and the rig substructure; the top end of the boring tower support is articulated with a sliding seat, a sliding oil cylinder is arranged between the sliding seat and the lower section boring tower, the front of a joint of the upper and lower section boring towers is provided with a folding articulated shaft, and the back surface of the joint of the upper and lower section boring towers is provided with positioning holes which are mutually matched; and an automatic plug pin mechanism matched with the positioning holes is arranged on the upper section boring tower or the lower section boring tower, and a double cylinder mutual assistance mechanism is arranged between the upper and lower boring towers. The folding boring tower provided by the invention adopts the double cylinder mutual assistance mechanism, the tower body can automatically complete spread or fold, the automatic degree is increased, and the performance of a boring apparatus is improved; and the sliding seat and the sliding oil cylinder are adopted to match, the work force and a lifting device are not needed in a tower rising process, the auxiliary expenses in a construction process is greatly reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a core drilling technical equipment, in particular to a folding drilling tower. Background technique [0002] Since 2006, the State Council promulgated the "Decision on Strengthening Geological Work". my country's mining industry has recovered rapidly, geological core drilling has grown rapidly, and investment in mineral exploration has continued to increase accordingly. Geological exploration equipment, vertical shaft core drilling rigs are still the absolute main force in the exploration market. XY-4, XY-42, XY-44, and XY-5 drilling rigs basically cover shallow and middle layer exploration. Vertical shaft core drilling rigs, most construction units, are equipped with square towers or A-shaped towers. To install, dismantle and transport the tower requires a certain amount of manpower, material resources and relocation equipment, which is relatively high in auxiliary construction costs. To reduce the construction process, d...
