Problems solved by technology
[0003] At present, the power head is used to lift and lower the drill pipe. Due to the limitation of the stroke, only one 2-2.5-meter drill pipe can be lifted at a time. As the drilling depth increases, especially after 15 meters, the power head is used for lifting and lowering. Drilling time is greatly increased, the labor intensity is high, and the efficiency is low, which seriously affects the comprehensive drilling efficiency

Embodiment 1
[0022] Such as Figure 1-3 As shown, a double cylinder pushing device of a power head includes a vertically moving backboard 1 , a laterally moving cylinder 5 , and a laterally moving backboard 8 . Among them, the vertically moving backboard 1 is arranged on the mast 10 of the drilling rig and can move vertically along the height direction of the mast 10, and the horizontally moving backboard 8 is arranged on the vertically moving backboard 1 and can be moved horizontally relative to the vertically moving backboard 1. To move laterally, the power head 6 is arranged on the traversing backboard 8, so that when the traversing backboard 8 moves horizontally relative to the vertical moving backboard 1 in the horizontal direction, it drives the power head 6 to realize lateral movement.
[0023] In this embodiment, vertically refers to the height direction of the mast 10 when it is kept upright, and laterally refers to the horizontal direction perpendicular to the height direction of...

The invention provides a double-oil-cylinder pushing device of a power head. The double-oil-cylinder pushing device comprises a vertical moving back plate, transverse moving oil cylinders and a transverse moving back plate; the power head is fixed on the transverse moving back plate; the vertical moving back plate is arranged on a mast of a drilling machine and can vertically move along the height direction of the mast; the transverse moving back plate is arranged on the vertical moving back plate and can transversely move relative to the vertical moving back plate in the horizontal direction; and transverse movement of the transverse moving back plate is pushed by the transverse moving oil cylinders symmetrically arranged on the upper side and the lower side of the transverse moving back plate. According to the device, the situation that stress on the two sides of the power head during sliding is unbalanced is improved through the symmetrically-arranged transverse moving oil cylinders, the locking force of the power head in a working state is increased, and the stability of the power head in a drilling working state is improved.
Description
technical field [0001] The invention relates to a mechanism of an audio frequency vibration drilling machine, in particular to a moving device of a power head. Background technique [0002] In the past ten years, in order to meet the needs of increasing environmental geological survey work, my country's engineering survey research field has successively developed large (small) audio-frequency environmental protection sampling drilling rigs. The Second Exploration Bureau of the General Administration of Coal Geology of China has successively developed the audio-frequency vibration drilling rig and the audio-frequency environmental protection sampling drilling rig. The structural layout and aesthetics have been greatly improved, filling the gap in the development of the 50-meter audio-frequency environmental protection drilling rig in China, and basically reaching the domestic leading level. . Drilling rigs are effective in non-pollution and weak-disturbance sampling in compl...
