HYDRAULIC BREAKER WITH DISPLAY OPERATED BY SENSOR FOR SENSING UNLOCKING AND BREAKAGE OF LONG BOLT OR BREAKAGE CHISEL PIN

摘要

The present invention relates to a hydraulic breaker with a display operated by a sensor for sensing unlocking and breakage of a long bolt or breakage of a chisel pin, which senses unlocking or breakage of a long bolt or breakage of a chisel pin by being mounted on a main body to combine components against vibration or impact and which can prevent deterioration of performance of a hydraulic breaker by sensing damage to a chisel pin to fix a chisel by being mounted on a front head by the operation of a piston to strike the chisel, comprising: a plurality of first sensors (510) mounted in a lower part of a number of hexagonal nuts (450) to prevent unlocking of a long bolt (440) by fixing the long bolt (440); second sensors (810) mounted on both ends of a wire head (730) connected to a wire (720) which is inserted into a through-hole (710) formed in a chisel pin (470) so as to operate in a non-contact type to sense damage of the chisel pin (470); a sending part (900) to send signals detected by the plurality of first sensors (510) and second sensors (810); and a receiving part (1000) to receive signals sent from the sending part (900), to operate the display by detection of the first sensors (510) and the second sensors (810).
