Abstract

The invention discloses a drilling machine for a large-diameter down hole hammer. The drilling machine comprises a chassis (1), a jib lubbing mechanism (4), a main rolling steel wire rope (8), a mast (5), a power head (9), a gas inlet channel (6), a drill stem (14) and a goose head (7), and further comprises a group of sleeves (13) which can be inserted into drilling holes, and a deslagging head (11), wherein the power head (9) is mounted on the mast (5) by adopting a forerake and sidesway structure; the deslagging head (11) can be in butt joint with the upper ends of the sleeves (13); the upper end of a deslagging tube (12) is connected to a slag outlet of the deslagging head (11); the lower end of the mast (5) is provided with a telescopic front supporting leg (17); and a pile gripper (18) is connected with the telescopic front supporting leg (17). The drilling machine is reliable in performance, complete in function, high in degree of automation, capable of realizing entire process supervising for large-diameter down hole hammer drilling and casing, suitable for various geological conditions and capable of conveniently and efficiently carrying out drilling construction.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a down-the-hole hammer drilling machine in the field of pile foundation construction machinery. Background technique [0002] The construction hole diameter of traditional down-the-hole hammer drilling rigs is less than 400mm. At present, there is no special drilling rig for the construction of large-diameter down-the-hole hammers exceeding 400mm. The difficulty is that the vibration caused by the construction of large-diameter down-the-hole hammers has a great impact on the surrounding environment. The air in the ground will disturb the formation, which requires follow-up protection of the wall casing, and the whole casing casing wall of the deep hole needs to be connected by multiple casings, which will affect the construction efficiency. The above problems are the main obstacles preventing the promotion of large-diameter down-the-hole hammer construction methods, and the d...
