Device and method capable of measuring drilling depth of hydraulic drill carriage

Abstract

The invention discloses a device and method capable of measuring the drilling depth of a hydraulic drill carriage. The device comprises a drill bit, a drill pipe, a gripper, a gripper opening cylinderoil inlet pipe, a guide rail, a propulsion cylinder, rare earth magnets, a hydraulic chuck, a hydraulic chuck oil inlet pipe, a proximity switch, a gyrator reduction gearbox and a small water adaptersubstitute. The device and method capable of measuring the drilling depth of the hydraulic drill carriage have the beneficial effects that a drilling rig can accurately record the drilling depth in real time in the drilling process of the drill bit, and personnel does not need to record the number of drill pipes and supervise; the advance and retreat of the drill pipe are judged by the oil inletpipeline pressure of the hydraulic chuck, the pipeline pressure of the open side of the gripper, the pipeline pressure of the feeding side of an oil cylinder and the pipeline pressure of the retracting side of the oil cylinder, and the record of the positive and negative values of the stroke is convenient; the proximity switch is composed of an inductive element and a single-chip microcomputer, and can sense a plurality of rare earth magnets for collecting signals so that the proximity switch can record the stroke when continuously sensing two rare earth magnets; and the small water adapter substitute is used for ventilation and drainage in the drilling process, and the punching operation is facilitated for workers.

[0002] The history of China's industrialized coal production is like a wave-like tide, which has been rushing to today. Science and technology are advancing day by day, and the pace of innovation is changing with each passing day. The rapid growth of the coal industry has driven the rapid development of the national economy and reinterpreted the brand-new concept of the coal industry—— ——In the era of safe and efficient mining, in China, we have always focused on coal mine gas, water damage control, and coal seam geological exploration to create conditions for safe production in coal mines. Drilling rigs and drilling trucks are the main exploration equipment in coal mines at present. There is a huge demand for use. The number of drilled holes is even more numerous, and the geological conditions of each mine are different, and the drilling process is also different, which leads to different hole depths required by the process. At present, the mining rig team is mostly outsourced, and the mine pays according to the number and depth of the holes. At present, the measurement of the hole depth can only be recorded manually by counting the number of drill pipes (that is, the hole depth = the number of drill pipes × the length of the drill pipe). There may still be deviations due to human factors
