Abstract

The invention relates to a monitoring, early warning and protecting simulation visual system for the working state of a drill rod of a rotary drilling rig. The monitoring, early warning and protecting simulation visual system comprises a display and control all-in-one machine, a main winch depth sensor, a power head position sensor and a power head weight sensor, wherein the display and control all-in-one machine is connected with a power supply and is connected to a hydraulic or electric appliance execution element, the display and control all-in-one machine is connected with the main winch depth sensor which is used for measuring the drilling depth, and the display and control all-in-one machine is connected with the power head position sensor which is used for monitoring the position of a power head and the power head weight sensor which is used for monitoring the weight of the power head; the main winch depth sensor is fixedly installed on a main winch of the rotary drilling rig or a component associated with a steel wire rope; the power head position sensor is fixedly installed on a mast or the power head of the rotary drilling rig or a component connected with the mast and the power head and is used for connecting the power head with the mast and measuring the position of the power head on the mast; and the power head weight sensor is installed on a pin shaft which is used for connecting the power head with a pressurizing oil cylinder or other components which can measure the weight change of the power head and are directly or indirectly connected with the power head.

Description

technical field [0001] The invention relates to the technical field of drill pipe protection for rotary drilling rigs, in particular to a drill pipe working state monitoring, early warning and protection analog visual system for rotary drilling rigs. Background technique [0002] The drill pipe of the rotary drilling rig is a multi-section large set of small retractable structure. Counting from the outside to the inside is; 1-section rod, 2-section rod, 3-section rod, ... and so on. According to the type of drill pipe, there are different sections. During the lowering process of the drill pipe, the whole drill pipe starts to be lowered together. When one section of the pipe falls on the power head, it is supported by the buffer support of the power head, and the other section of the pipe stops moving downward. The main winch continues to lower, and the second and third sections continue to descend. The second section and the third section are lowered synchronously to the ...
