Intelligent idling system of rotary drilling rig

Abstract

The invention provides an intelligent idling system of a rotary drilling rig. The intelligent idling system of the rotary drilling rig comprises a shuttle valve group type idling identification module, an unlocking type idling identification module, a switching type idling identification module, an action button type idling identification module and an electrical controller, the modules are used for inputting idling identification signals into the electrical controller, the electric controller receives the identification signals of all the modules and converts the identification signals into output signals to an engine, the shuttle valve group type idling identification module comprises a power head pilot component, a main winch pilot component and a pressurizing pilot component, the unlocking type idling identification module comprises a walking unlocking button, a platform rotation unlocking button and a mast verticality adjusting unlocking button, the switching type idling identification module comprises a variable-amplitude switching button and an auxiliary winch switching button, and the action button type idling identification module comprises a caterpillar band oil cylinder stretching button and a caterpillar band oil cylinder contracting button. According to the system, automatic idling work of the rotary drilling rig can be completed only through five shuttle valves; and the automatic idling system is low in cost and low in system failure rate.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to an engine speed control system of a rotary drilling rig. Background technique [0002] Rotary drilling rigs are designed with an automatic engine idling system, that is, when the engine of the equipment is not turned off and the hydraulic system is not working, the engine needs to be placed in a low idle state, but when the hydraulic system is working, the engine speed needs to be increased, which can reduce Reduce fuel consumption, improve engine and hydraulic component life. Therefore, it is necessary to identify when the hydraulic system works and when it does not work. At this time, a shuttle valve group is generally designed on the pilot of the hydraulic system, and the pressure signal is extracted through the pressure switch as the identification signal of the automatic idle system of the electrical system controller; [0003] The actions of rotary drilling...
