Abstract

The invention relates to a limiting plug pin and a drill rod mechanical arm applying the limiting plug pin, and belongs to the technical field of drilling machine equipment. The limiting plug pin comprises a fixed base; a sliding groove is formed in the fixed base; a sliding block is slidably connected to the sliding groove; one end of the sliding block is connected with an extending mechanism capable of enabling the sliding block to move along the sliding groove; a limiting cavity perpendicular to the moving direction of the sliding block is formed in the sliding block; a limiting block capable of moving along the limiting cavity is arranged in the limiting cavity; the limiting block comprises a limiting block body and a connector detachably connected with the limiting block body; the end, away from the extending mechanism, of the connector extends out of the sliding block to be connected with a plug pin body; and a rotary positioning device and a horizontal positioning device of thedrill rod mechanical arm are positioned by the limiting plug pin. The mechanical limiting plug pin is adopted for positioning, the problem that a positioning device is prone to being affected by the environment and failing is solved, and the reliability of the positioning device is improved.

Description

technical field [0001] The invention belongs to the technical field of drilling rig equipment, and relates to a limit bolt and a drill pipe manipulator using the limit bolt. Background technique [0002] The positioning device of the existing manipulator for loading and unloading drill pipes is to set the synchronous positioning sensor assembly at the end of the manipulator so that the rotary arm of the manipulator is parallel to the axis of the drill pipe holder on the frame; by horizontally positioning the sensor assembly, the rotary arm of the manipulator is realized The angle with the horizontal plane is zero. The positioning device includes a controller and a sensor module connected to it, and the positioning of the manipulator is realized through the sensor and the sensor sensing block. [0003] The disadvantage of this positioning method is: the damp working environment of the coal mine underground drilling rig is easy to cause the sensor to fail; during the working ...
