Problems solved by technology

However, since various soil layers and rocks will increase the difficulty of the operation, the structure of the soil layer is changing during the construction of the drilling rig; especially when the drilling rig is drilling, it is easy to generate high friction and the drilling rig is subjected to high-intensity damping. Drilling is difficult; at this time, if the drilling rig encounters a rock layer that is difficult to drill during the continuous drilling process, it will be stuck, and the operation will no longer be possible

Abstract

The invention discloses a casing pipe emergency rotary torque enhanced control device of a fully slewing drilling machine and belongs to an engineering mechanical control system. The output parameter of a main machine is increased instantly through a group of electrical appliances and a hydraulic composite control system. When the main machine works normally, once the casing pipe cannot rotate caused by increased peripheral resistance, an emergency rotary torque enhanced device is started, so that the rotary torque is enhanced and the dilemma that the casing pipe cannot rotate is avoided.

Description

technical field [0001] The invention relates to a torque enhancement control device, in particular to a casing casing emergency rotation torque enhancement control device for a full-rotation drilling rig. Background technique [0002] With the continuous acceleration of my country's infrastructure construction, full-rotary drilling rigs, as emerging products in the construction machinery industry, have become the most ideal construction machinery for hole-forming operations in high-speed rail, elevated, and building foundation projects. The full-rotary drilling rig has the characteristics of high efficiency, high quality, and environmental protection. However, due to various soil layers and rocks that will increase the difficulty of the operation, the structure of the soil layer is changing during the construction of the drilling rig; especially when the drilling rig is drilling, it is easy to generate high friction so that the drilling rig is subjected to high-strength damp...
