The following terms are defined in consideration of the functions of the present invention, and they may vary depending on the intentions or customs of the client, the operator, the user, and the like. Therefore, the definition should be based on the contents throughout this specification. Like numbers refer to like elements throughout the drawings.

Example 1: Detection of loosening and breakage of long bolt

3 to 6, a hydraulic breaker 300 having a display operated by a sensing sensor for detecting the loosening and breakage of a long bolt or the breakage of a chisel pin according to the present invention includes a bracket 310, A mountain cap 320 mounted on an upper portion of the bracket 310, a piston (not shown) mounted in the bracket 310, and a checker 330 struck by the piston.

The hydraulic breaker 300 includes an upper head cap 410 and a front head 430 on which the cylinder 420 and the chisel 330 are mounted in order The body part 400 is constructed by combining the above-described components in an integrated state by using a plurality of long bolts 440 after assembly.

The body part 400 is inserted into and fixed to the bracket 310 coupled to the upper part of the mountain cap 320 to complete the hydraulic breaker 300.

The head cap 410 is coupled to the upper portion of the cylinder 420 and functions as a lid. In addition, the long bolt 440 is inserted through a bolt hole (not shown) formed in the head cap 410.

The cylinder 420 is installed at the lower part of the head cap 410. A piston operating in the up / down direction is installed by the hydraulic pressure of the operating oil supplied from the outside.

The front head 430 is installed at a lower portion of the cylinder 420 and is operated to prevent the piston 430 from being separated from the cylinder 420 and to receive the operating force of the piston of the cylinder 420 to crush the crushed material The chisel 330 is exposed and installed externally.

The long bolt 440 is inserted through the bolt hole of the head cap 410 and sequentially penetrates through the cylinder 420 and the front head 430. The long bolt 440 is fixed to the cylinder head A large diameter large diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter small diameter do.

In order to fix the long bolt 440, a plurality of hexagonal nuts 450 are fastened at the upper end to prevent loosening to fix the upper part.

A damper 460 is mounted on the upper portion of the long bolt 440 to prevent collision between the long bolt 440 and the mountain cap 320 due to vibration or impact when the hydraulic breaker 300 operates. The damper 460 is formed in a shape of a cross, the material of which is either MC nylon or Teflon. The height of the damper 460 is determined by the length of the bolt 440 protruding from the head cap 410 Is higher than a hex nut 450 fixing the long bolt 440 by a predetermined height. Also, when the size of the hydraulic breaker 300 is changed, the size of the long bolt 440 is also changed. The size of the damper 460 may be changed according to the size change.

In order to use the hydraulic breaker 300 having the display operated by the detection sensor for detecting the loosening and breakage of the long bolt or the breakage of the chisel pin according to the present invention having the above-described structure, the body part 400 is fixed to the bracket 310, And then mounts the mountain cap 320 so as to be supplied with oil pressure to an operating device such as an excavator.

When the hydraulic pressure is supplied after the completion of the mounting, the hydraulic oil is repeatedly supplied / discharged to the inside of the cylinder 420, and the crush is crushed by hitting the chisel 330 with the operating force of the piston. At this time, vibration or impact force generated by the crushing action is transmitted to the body part 400 through the chisel 330. Part of the vibration or impact force is absorbed and destroyed by the body part 400 itself, but the rest is transmitted through the long bolt 440.

 The damper 460 is compressed in accordance with the moving direction of the long bolt 440 so that the long bolt 440 and the mountain cap 320 are preferentially compressed while moving the long bolt 440, Thereby absorbing vibration and impact force and extinguishing it.

However, when such vibration or impact force is transmitted for a long time, the hexagon nut 450 fixing the long bolt 440 is loosened or broken. Therefore, in order to detect that the hex nut 450 is loosened or broken, the hex nuts 450 for fixing the long bolt 440 detect the loosening and breakage of the hex nut 450, The first sensing sensor 510 is mounted between the hex nut 450 and the first sensing sensor 510 to sense the loosening and breakage of the hex nut 450, A washer 520 having a detection groove for protecting the first sensing sensor 510 is provided. Therefore, the number of the hex nuts 450 is equal to the number of the first sensing sensors 510 and the washers 520.

The washer 520 is fixed by two washer fixing pins 530 formed at a lower portion of the washer 520. The washer fixing pins 530 are disposed at an angle of 180 °, 410, respectively. Therefore, eccentricity of the washer 520 due to the rotation of the hex nut 450 is prevented by the washer 520 fixed by the washer fixing pin 530. Therefore, the number of the washer fixing pins 530 is twice that of the washer 520.

A plurality of first sensing sensors 510 are mounted on the head cap 410. The plurality of first sensing sensors 510 are mounted on a lower portion of the hex nut 450, Non-contact type. Accordingly, the first sensing sensor 510 senses the spacing of the hex nut 450. FIG. Of course, there is no problem if the spacing of the hex nut 450 is within the sensing range of the first sensing sensor 510. However, due to vibration or shock caused by the chisel 330, The first sensing sensor 510 recognizes that the elongated bolt 440 is loosened or broken and outputs the elongated bolt 440 to the receiving unit 1000 through the transmitting unit 900 to be described later A sensing signal is transmitted to allow the operator of the hydraulic breaker to recognize it.

In addition, when the object to be crushed is crushed by the chisel 330, the chisel 330 is temporarily engaged with the air hole in the air, The chlippin 470 is hit by the repetition of the blow, and the chisel pin 470 damages one of the outer side surfaces of the two outer side surfaces. Accordingly, when one of the outer surfaces of the chisel pin 470 is damaged by the hitting of the piston, the chisel pin 470 is separated from the coupling hole 480 in order to prevent breakage of the chisel pin 470 And the chisel pin 470 is inserted reversely so that the other outer side surface of the chisel pin 470 is opposed to the stroke of the piston and the blow of the chisel.

However, by repeating the crushing operation, the chisel pin 470 is eventually destroyed, and the front head 430 is damaged due to the vibration of the chisel 330 which is released due to the breakage of the chisel pin 470 Even the bracket 310 surrounding the front head 430 can be damaged.

A wire 720 and a wire head 730 are inserted into the through hole 710 of the chisel pin 470 according to the present invention. The wire 720 is inserted into the through hole 710, Both ends of the wire 720 are inserted into the through hole 710 and are connected to the wire head 730 so as to be connected to the second sensing sensor 810 mounted on both ends of the chisel pin 470 in a non- Mounted.

Here, the second sensing sensor 810 detects the separation of the wire head 730. Of course, there is no problem if the spacing of the wire head 730 is within the sensing range of the second sensing sensor 810. However, if the outer surface of the chisel pin 470 is broken due to the impact of the piston, The wire 720 is pressed by the wire 470 and the wire 730 and the second sensor 810 are spaced apart from each other to sense breakage of the chisel pin 470.

The chislip pin 470 is connected to the receiving part 1000 through the transmitting part 900 to be described later by sensing the separation between the wire head 730 and the second sensing sensor 810, It transmits the damage signal as an acoustic signal and simultaneously transmits the light signal through the display so that the operator of the hydraulic breaker 300 recognizes the damage.

The magnetic switch 910 is activated by the sensing signal generated by the first sensing sensor 510 and the second sensing sensor 810, The digital signal processor 920 digitally filters the digital signal converted by the A / D converter having the analog signal generated by the operation, and the transmission signal processor 930 processes the filtered digital signal as a transmission signal The transmission signal is transmitted to the reception unit 1000 to be described later by the transmission antenna 940. At this time, the transmission MCU 950 transmits the signal to the magnetic switch 910, the digital signal processing unit 920, 930 and the transmitting antenna 940. It is checked whether the hex nuts 450 of the plurality of hex nuts 450 are loosened or broken and the chisel pin 470 is broken by the processed transmission signal, Checking, The transmission control unit 960 transmits the status to the receiving unit 1000 through the transmitting antenna 940.
