Abstract

The invention discloses a full-casing full-rotation drilling rig, which relates to engineering machinery. Including power station, working device and auxiliary drilling tools. The power station is external, and the working device includes a base, a power support platform, a column, a lifting platform and a casing clamping device, and there is an outrigger cylinder in the base for leveling. Drawing cylinders, hydraulic motors, gearboxes, clamping cylinders and gear transmissions are the main devices that transmit power to the casing, driving the casing to rotate, rise and fall. Auxiliary drilling tools include casings of various specifications, grabs, multi-head grippers, etc. The full-casing full-rotary drilling rig has four main actions: leveling, clamping, turning, pressing and pulling. The engine in the power station drives a number of hydraulic pumps, which are connected to the working device through hydraulic hoses and transmit the power to the corresponding actuators.

Description

technical field [0001] The invention relates to a construction machine, in particular to a full-casing full-rotation rotary drilling rig. Background technique [0002] With the continuous acceleration of my country's infrastructure construction, more and more constructions are being carried out in various complex geological environments such as plateaus, mountains, hills, beaches, rivers, lakes and tidal flats. During on-site construction, quicksand, karst caves, rock formations, etc. are often encountered underground. Various complex geological conditions. In traditional crawler excavators, the drill pipe is separated from the casing, and the casing is short, so it can only play the role of partial wall protection. The problem of landslides cannot be avoided, which affects the quality of the project. The crawler excavator has poor neutrality and it is difficult to guarantee the verticality. Contents of the invention [0003] In order to solve the above technical problems...
