A counting device and counting method for measuring the cumulative rock drilling depth of rock drilling equipment

Abstract

The invention discloses a mechanical counting device for metering the accumulative rock drilling depth of rock drilling equipment. The device comprises a synchronous counting wheel, a single chip microcomputer, a pressure relay and a register, wherein the synchronous counting wheel is composed of a rotating piece with a signal source and an induction piece, the rotating piece is connected with a rotating shaft of a hydraulic motor of the rock drilling equipment, the induction piece is connected with the single chip microcomputer, the pressure relay is arranged on a hydraulic cylinder on the hydraulic motor and is in signal connection with the single chip microcomputer, and the register is in signal connection with the single chip microcomputer and used for displaying the accumulative rock drilling depth. The synchronous counting wheel is adopted to convert the accumulative rock drilling depth of the rock drilling equipment into the number of rotating cycles of the rotating piece, the pressure relay and the register are used for controlling the counting time and displaying the accumulative rock drilling depth, the structure is simple, and counting is accurate. The invention further provides a counting method. The method and device are special for metering the accumulative rock drilling depth of the hydraulic rock drilling equipment.

Description

Technical field [0001] The invention belongs to the field of measuring rock drilling depths in mines, and in particular relates to a counting device and a counting method for measuring the cumulative drilling depth of rock drilling equipment. Background technique [0002] In recent years, mining machinery, especially rock drilling equipment, has gradually changed from pneumatic rock drilling equipment to full hydraulic equipment, which has greatly improved the efficiency of rock drilling operations. However, most domestic manufacturers only simply imitate foreign equipment, no matter in terms of functional structure, performance efficiency, or machine life, they cannot compare with foreign countries. How to narrow this technological gap and accelerate the development of their own high-performance products, equipment manufacturers need to perform performance parameter evaluation and service life tracking of some key parts of machinery, especially vulnerable parts. Therefore, it i...
