Abstract

The invention relates to a rod carrying monitoring system for a drill rod of a rotary drilling machine, belonging to monitoring systems of engineering machinery. The monitoring system comprises a pin shaft sensor, a sounding coder, a controller, a pilot solenoid valve and a main winding system, wherein the pin shaft sensor is connected to the center of the main winding pulley, the sounding coder is connected with a rotating shaft at one side of a main winding drum, the output ends of the pin shaft sensor and the sounding coder are both connected with the input end of the controller, the output end of the controller is connected with the pilot solenoid valve, the pilot solenoid valve is connected with a main winding motor of the main winding system, the controller is arranged in an electric control box, the pilot solenoid valve is installed on the drilling machine car body, the main winding system and the main winding motor are connected with the winding drum, the main winding drum is connected with the drill rod through a steel wire rope, the steel wire rope pass through a main winding pulley groove, a main winding pulley is installed on a main winding pulley bracket. The rod carrying monitoring system has the advantages of simple structure, capability of effectively monitoring the rod carrying condition of the drill rod and judging whether the rod carrying of the drill rod happens or not without depending on the experience of operators, and good reliability and practical applicability.

Description

technical field [0001] The invention relates to a monitoring system for construction machinery, in particular to a monitoring system for drilling rods of rotary drilling rigs. Background technique [0002] Rotary drilling rigs generally have a main machine, a mast, a drill pipe and a main winch system. The main winch system includes a main roll drum, a wire rope, a main roll motor and a main roll pulley. The mast is installed on the main machine. After the mast is erected, the drill The mast is located on the front side of the mast. The main roll pulley is connected to the upper end of the mast. The main roll drum is installed on the main machine. The main roll motor is located on one side of the main roll drum. On the drum, the other end of the wire rope is connected to the drill pipe through the main coil pulley. [0003] The drill pipe of the rotary drilling rig adopts a telescopic drill pipe, and each section of the drill pipe adopts a rectangular insert to match the ou...
