Description

technical field

[0001] The invention belongs to the technical field of mechanical equipment, and specifically relates to a direct-push soil sampling drilling rig. Background technique

[0002] At present, when the rotary drilling rig is configured with the CFA method, it is usually implemented on models below 280, and it is difficult to achieve a large drilling depth increase on a small drilling rig according to the conventional drilling rig classification.

[0003] CAF usually completes pile hole construction with large drilling depth by increasing the height of the mast or changing to a larger model.

[0004] A rotary drilling rig with a publication number of CN203639040U, a lifting device, a lifting system, and a rotary drilling rig with the same, include a fixed pulley block and a movable pulley block that are arranged oppositely on the upper and lower sides, and a fixed pulley block connected to the movable pulley block and the fixed pulley block. The telescopic oil cy...
