Description

TECHNICAL FIELD [0001] The present invention relates to a breaker, a long bolt breakage monitoring system and a method for monitoring a long bolt breakage,

The present invention relates to construction equipment including a breaker, and more particularly to a construction equipment including a breaker having a cylinder for receiving the piston to reciprocate the piston.

A breaker is a device used for crushing rocks by striking a chisel that touches an object through a reciprocating motion of the piston. In a large construction site, a hydraulic attachment type mounted on a heavy equipment vehicle such as an excavator is mainly used .

Rock crushing work is one of the important factors in the work speed due to the construction period and so on. Accordingly, the conventional breaker has a long stroke mode in which the stroke distance of the piston is lengthened so as to enhance the hitting force for crushing and carcass destruction according to the operation of the operator, and a long stroke mode in which the hitting speed is improved And is configured to change the short stroke mode.

On the other hand, as the breaker hits the rock, the long bolt may be damaged by its impact.

When the long bolt is loosened, the binding force of the parts of the breaker is weakened. In such a state, if the breaker continues to strike the rock, the breaker may be damaged. It is therefore important to detect that the long bolt is broken.

The existing breaker could not detect whether the bolt was broken, and the breaker was broken.

A more detailed description of the breaker 1000 will be described later.

The carrier 120 can be largely divided into a traveling body 121 and a rotating body 122.

The traveling body 121 is mainly provided as a crawler type or a wheel type, and in some cases, it may be a crane type or a truck type.

The rotating body 122 is mounted on the traveling body 121 so as to be rotatable with respect to the axis perpendicular to the paper.

The rotating body 122 is provided with a connecting member 123 such as a boom or a arm. The breaker 1000 may be detachably attached to the end of the connecting member 123 in a manner that the breaker 1000 is fastened in an attachment type or fastened through the coupler 140. [

The connecting member 123 is mainly composed of two or more members fastened in a linking manner, and can be connected to the cylinder to perform an operation of bending or expanding, a stretching and the like by the expansion and contraction of the cylinder. The connecting member 123 can place the breaker 1000 attached to its end by this action on the pita boot.

Hydraulic pressure may be applied to the breaker 1000 so that the mounted breaker 1000 may be operated or hydraulic pressure may be applied to each part of the carrier 120 including the boom or arm or the coupler 140, And a hydraulic tank 160a for storing hydraulic oil may be installed.

Hereinafter, the breaker 1000 according to the embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG.

As shown in FIGS. 2 and 3, for example, the breaker 1000 may include a mounting bracket 1200, a main body 1400, and a chisel 1600. The main body 1400 has a cylinder 1430 and a piston 1440 accommodated in the cylinder 1430 to generate a hitting force in the breaker 1000. The main body 1400 includes a piston 1440 accommodated in the cylinder 1430, The piston 1440 reciprocates to generate a hitting force. The chisel 1600 directly hits the pit bulge and the lower portion of the main body 1400 (the piston 1440 advances (advances) in the following description to the upper side of the main body 1400 so as to hit the lower end of the piston 1440 And defines the upward direction in which the piston 1440 is moved upward (downward).

The mounting bracket 1200 is coupled to the upper end of the main body 1400 and serves as a connection between the carrier 120 and the main body 1400.

The main constituent of the main body 1400 may be a cylinder 1430 and a piston 1440.

For example, the piston 1440 is provided in a cylindrical shape, and the cylinder 1430 may be provided in a hollow cylindrical shape so that the piston 1440 can be inserted and reciprocated.

The inner surface 1437 of the cylinder is provided with various hydraulic ports 1433, 1434, 1435 and 1436 for supplying hydraulic pressure to the inside of the cylinder 1430 or discharging the hydraulic pressure from the inside of the cylinder 1430.

The piston 1440 includes at least a small diameter portion 1446, a first large diameter portion 1444 located on the upper side of the small diameter portion 1446 and a second large diameter portion 1442 located on the lower side of the small diameter portion 1446 .

The hydraulic pressure applied to the inside of the cylinder 1430 through the hydraulic port acts on the stepped surfaces 1444a and 1442a formed by the first large diameter portion 1444 and the second large diameter portion 1442, (1430). ≪ / RTI >

Accordingly, by appropriately designing the stepped surfaces 1444a and 1442a of the hydraulic port and the piston 1440 formed in the cylinder 1430, it is possible to control not only the reciprocation of the simple piston 1440 but also the stroke distance of the piston 1440 have.

The front head 1450 and the head cap 1420 can be connected to the lower end and the upper end of the cylinder 1430, respectively.

The front head 1450 is provided with a chisel pin (not shown) to which the chisel 1600 is attached and the chisel 1600 is hammered by the lower end of the piston 1440 by advancing the piston 1440 by a chisel pin (not shown) In a suitable position.

The head cap 1420 has a gas chamber (not shown) therein and the gas chamber can impart an appropriate damping effect to the piston 1440 as its volume is compressed upon retraction of the piston 1440.

The structure and structure of the breaker 1000 described above are only an example of the breaker 1000 according to the present invention. The breaker 1000 according to the present invention may have a similar function to the breaker 1000, It should be understood that other striking devices are also included.

A circuit diagram of the breaker 1000 according to the embodiment of the present invention will be described with reference to FIG.

4, a piston 1440 is inserted into the cylinder 1430, and a chisel 1600 is disposed below the piston 1440. As shown in FIG.

The piston 1440 may be formed with a small diameter portion 1446, a first large diameter portion 1444 located on the upper side of the small diameter portion 1446 and a second large diameter portion 1442 located on the lower side of the small diameter portion 1446 have.

The first large diameter portion 1444 and the second large diameter portion 1442 may have substantially the same outer diameter as the inner diameter of the cylinder 1430. Accordingly, the lower portion of the cylinder 1430, A front chamber 1431 may be formed between the neck portion 1442 and a rear chamber 1432 may be formed between the upper side of the cylinder 1430 and the first large diameter portion 1444.

A backward port 1433 is formed in the front chamber 1431 and a backward port 1433 can be connected to the hydraulic source 160 through a backward line 1433a.

Accordingly, the hydraulic pressure can be applied to the front chamber 1431 by the operating oil flowing into the backward port 1433 from the hydraulic pressure source 160 through the backward line 1433a.

The hydraulic pressure applied to the front chamber 1431 acts on the step surface 1442a of the second large-diameter portion 1442, and the piston 1440 can be subjected to a backward force.

The rear chamber 1432 is formed with a forward port 1434 and the forward port 1434 can be connected to the control valve 1460 through the forward line 1434a.

The control valve 1460 may be disposed at any one of the forward position 1460-2 or the backward position 1460-1 and the forward position 1460a may be disposed at the hydraulic source 160 And the forward line 1434a can be connected to the hydraulic tank 160a in the backward position 1460-1.

Accordingly, when the control valve 1460 is disposed in the forward position 1460-2, the rear chamber 1432 is supplied with the hydraulic fluid from the hydraulic source 160 through the control valve 1460 and the forward line 1434a to the forward port 1434 The hydraulic pressure can be applied by the operating oil.

The hydraulic pressure applied to the rear chamber 1432 acts on the stepped surface 1444a of the first large diameter portion 1444 and a forward force is applied to the piston 1440. [

When the control valve 1460 is disposed in the backward position 1460-1, the rear chamber 1432 is connected to the hydraulic tank 160a via the forward line 1434a and the control valve 1460, 1460-2, the hydraulic fluid flowing into the rear chamber 1432 is discharged to the hydraulic tank 160a.

In this structure, since the stepped surface 1444a of the first large diameter portion 1444 has an area larger than the stepped surface 1442a of the second large diameter portion 1442, the control valve 1460 is moved to the forward position 1460-2 The forward force is greater than the backward force and the piston 1440 can advance.

Conversely, when the control valve 1460 is disposed in the reverse position 1460-1, the hydraulic pressure applied from the hydraulic pressure source 160 acts on only the stepped surface 1442a of the second large-diameter portion 1442, can do.

As a result, the reciprocating motion of the piston 1440 can be realized as the control valve 1460 is disposed in the forward position 1460-2 or the backward position 1460-1.

In one example, the control of the position of the control valve 1460 may be hydraulic.

That is, the control valve 1460 may be a hydraulic valve in which the forward position 1460-2 and the backward position 1460-1 can be selected in accordance with the input hydraulic pressure signal.

At both ends of the control valve 1460, a forward action surface 1464 and a backward action surface 1462, which are connected to the hydraulic line, respectively, may be provided.

Here, the forward action surface 1464 may be connected to the long stroke line 1435a and the forward control line 1464a which is branched to the short stroke line 1436a.

The reverse working surface 1462 can be connected to the hydraulic source 160 via the reverse control line 1462a.

In this structure, the forward action surface 1464 has an area larger than the backward action surface 1462, so that when both hydraulic surfaces are applied to the both action surfaces, the control valve 1460 can be disposed at the forward position 1460-2 Accordingly, the piston 1440 can advance.

Conversely, when hydraulic pressure applied from the hydraulic pressure source 160 is applied only to the reverse operation surface 1462, the control valve 1460 can be disposed from the advance position 1460-2 to the reverse position 1460-1, (1440) can be reversed.

The long stroke line 1435a is connected to the long stroke port 1435 formed in the cylinder 1430. [ The long stroke port 1435 may be formed between the forward port 1434 and the backward port 1433 of the cylinder 1430 so that the long stroke port 1435 can be connected to or disconnected from the front chamber 1431 according to the position of the piston 1440.

More specifically, the long stroke port 1435 is connected to the front chamber 1431 when the piston 1440 advances and the second large diameter portion 1442 is on the long stroke port 1435 or below the long stroke port 1435, Is disconnected.

The long stroke port 1435 is connected to the front chamber 1431 when the piston 1440 is reversed and the second large diameter portion 1442 is located above the long stroke port 1435.

Accordingly, when the long stroke port 1435 is connected to the front chamber 1431, the hydraulic pressure from the hydraulic pressure source 160 is supplied to the reverse line 1433a, the reverse port 1433, the front chamber 1431, the long stroke port 1435, The long stroke line 1435a and the forward control line 1464a to the forward action surface 1464 so that the control valve 1460 can be disposed at the forward position 1460-2.

The short stroke line 1436a may be connected to the short stroke port 1436 formed in the cylinder 1430. [ The short stroke port 1436 is formed between the forward port 1434 and the backward port 1433 of the cylinder 1430 so that the short stroke port 1436 can be connected to or disconnected from the front chamber 1431 according to the position of the piston 1440, May be formed at a position closer to the backward port (1433) than the port (1435).

More specifically, the short stroke port 1436 is connected to the front chamber 1431 when the piston 1440 advances and the second large diameter portion 1442 is on the short stroke port 1436 or is located forward of the short stroke port 1436. [ The connection is blocked.

The short stroke port 1436 is connected to the front chamber 1431 when the piston 1440 is retracted and the second large diameter portion 1442 is located rearward of the short stroke port 1436.

Here, on the short stroke line 1436a, a shift valve 1470 for controlling the short-circuit of the short stroke line 1436a may be provided.

The shift valve 1470 may be selectively disposed at one of the long stroke position 1470-1 and the short stroke position 1470-2 and the short stroke line 1436a And connects the short stroke line 1436a at the short stroke position 1470-2.

Thus, the long stroke mode and the short stroke mode of the piston 1440 can be determined by the transmission valve 1470. [

The shift valve 1470 is disposed at the short stroke position 1470-2 and the second large diameter portion 1442 is positioned further rearward than the short stroke port 1436 so that the short stroke port 1436 and the front chamber 1431 The hydraulic fluid is supplied to the hydraulic source 160, the reverse line 1433a, the reverse port 1433, the front chamber 1431, the short stroke port 1436, the shift valve 1470 and the forward action surface 1464, Can be reached sequentially.

With this structure, the piston 1440 can selectively perform the reciprocating motion in the long stroke mode and the short stroke mode according to the position of the speed change valve 1470.

In one example, the shift valve 1470 may automatically switch between the long stroke position 1470-1 and the short stroke position 1470-2 by the controller 180, Stroke position 1470-1 and the short stroke position 1470-2.

The breaker 1000 may further include a shutoff valve 1480 for selectively shutting off the flow of the hydraulic fluid.

The shutoff valve 1480 may be installed in a line where the hydraulic oil is to be moved, and may selectively allow the flow of the hydraulic oil or block the flow of the hydraulic oil.

In one example, the shutoff valve 1480 may allow the flow of hydraulic fluid in the connecting position 1480-2 and may block the flow of hydraulic fluid in the cutoff position 1480-1.

In one example, shutoff valve 1480 is located on advancement control line 1464a and extends from actuating oil or short stroke port 1436, which is moved from long stroke port 1435 to advancement action surface 1464, The flow of the hydraulic fluid to be transferred to the first hydraulic pump may be allowed or blocked.

If the shutoff valve 1480 is disposed in the shutoff position 1480-1 to shut off the flow of hydraulic fluid, hydraulic pressure is not applied to the forward action surface 1464 and the control valve 1460 is in the reverse position 1460- 1) to the forward position 1460-2.

Therefore, the hydraulic fluid is not supplied from the hydraulic pressure source 160 to the rear chamber 1432 by the control valve 1460 in the reverse position 1460-1, so that the reciprocation of the piston 1440 can be stopped.

The installation position of the shutoff valve 1480 is not limited to the above-mentioned position, but may be provided on the backward line 1433a or on the forward line 1434a, for example.

Further, the shutoff valve 1480 may be installed in a line through which hydraulic oil is discharged from the hydraulic pressure source 160. [

In this case, when the shutoff valve 1480 interrupts the flow of the hydraulic oil, the hydraulic oil supply from the hydraulic pressure source 160 to the cylinder 1430 can be shut off.

Hereinafter, a technique for monitoring breakage of the long bolt 1402 that detects the breakage of the long bolt 1402 using the detection sensor 150 will be described.

The breaker 1000 can be vibrated by the reciprocating movement of the piston 1440 on the cylinder 1430 and the long bolt 1402 can be broken by the vibration.

When the long bolt 1402 is broken, the long bolt 1402 does not fix the cylinder 1430, the front head 1450, and the head cap 1420, and is in a released state (the cylinder 1430, the front head 1450, And the head cap 1420 can not be coupled to each other).

When the long bolt 1402 is broken, the cylinder 1430, the front head 1450, and the head cap 1420 may be spaced apart from each other and may be ruptured or struck to each other by the vibration of the breaker 1000 .

Therefore, the detection sensor 150 may be installed in the breaker 1000 to detect that the long bolt 1402 is broken.

For example, the detection sensor 150 can detect that the long bolt 1402 is broken.

For example, the detection sensor 150 may be disposed in a receiving space 1402-4 formed in the long bolt 1402. [

For example, the sensing sensor 150 may be formed in the second through hole 2403-4 formed in the washer 1403 or in the first through hole 3402-5 formed in the long bolt 1402, Hole 4420-3.

For example, the detection sensor 150 may detect breakage of the long bolt 1402 by an electrical short.

At this time, the detection sensor 150 may detect a breakage of the long bolt 1402 by sensing a current or a resistance.

That is, when the long bolt 1402 is broken, the detection sensor 150 installed on the long bolt 1402 can be broken by interlocking with the breakage of the long bolt 1402.

The detection sensor 150 includes a body 150-2 inserted into the accommodation space 1402-4, a wire 150-3 for applying a current to the body 150-2, and a wire 150-3 And a terminal 150-1 coupled to the body 150-2 to connect the body 150-2 with the body 150-2.

In addition, the body 150-2 may be formed of a PCB 150-2a through which electricity is conducted. The body 150-2 may include a conductor 150-2c through which electricity is conducted and an insulator 150-2b insulated between the conductor 150-2c and the long bolt 1402. [ However, the body 150-2 is not limited to this, and may mean any means that can be insulated from the long bolt 1402 with electricity flowing from the standpoint of a person skilled in the art.

The terminal 150-1 is connected to the body 150-2, So that the electric wire 150-3 can be connected. The terminal 150-1 may exist only at one end of the body 150-2, or may exist at both ends of the body 150-2. This can be variously modified in consideration of the purpose of use, production situation, and the like at a level that is obvious to a person skilled in the art.

The electric wire 150-3 can electrically connect the body 150-2 and the galvanometer (not shown) or the controller 180 and the body 150-2. However, the present invention is not limited thereto, and all the sensing means capable of detecting the breakage of the long bolt 1402 at a level obvious to a person skilled in the art can be connected to the electric wire 150-3.

For example, the detection sensor 150 can detect a breakage of the long bolt 1402 by sensing a change in the position of the accommodation space 1402-4 using a position displacement sensor.

At this time, the position displacement transmitter (not shown) of the sensor 150 is disposed at one end of the long bolt 1402, and the position displacement receiver (not shown) of the sensor 150 is positioned at the other end of the long bolt 1402 As shown in FIG. The position displacement transmission unit may radiate a laser to the accommodation space 1402-4 and receive the laser displacement from the position displacement reception unit to sense a change in the positional displacement of the accommodation space 1402-4. The positional displacement receiving unit can detect that the positional displacement of the accommodation space 1402-4 fluctuates when the long bolt 1402 is broken.

For example, the sensing sensor 150 senses a liquid fluid that is broken and leaks, such as a breakage of the long bolt 1402, and can detect breakage of the long bolt 1402.

At this time, the body 150-2 may be a tube containing a fluid. A leak sensor may be disposed at the upper end or the lower end of the long bolt 1402. When the long bolt 1402 is broken, the body 150-2 may be broken and the fluid may leak from the body 150-2. At this time, the leakage sensor senses the fluid and can detect the breakage of the long bolt 1402.

However, the present invention is not limited thereto, and may include all sensing sensors 150 capable of detecting breakage of the long bolt 1402 in accordance with the present invention.

For example, the first through holes 3402-5 may be disposed corresponding to the second through holes 3403-4.

For example, the first through holes 3402-5 may be disposed corresponding to the third through holes 4420-3.

Also, the meaning that the through-holes are disposed correspondingly can be said to be inserted from the outside to the accommodation space through the through-holes so that the electric wire can come into contact with the body inserted into the accommodation space have.

Further, the through holes can be arranged so that the electric wire can be inserted.

5, for example, the long bolt 1402 forms a receiving space 1402-4, and the detection sensor 150 detects the receiving space 1402-4 of the long bolt 1402 And can detect the breakage of the long bolt 1402.

In one example, the breaker 1000 may include a head cap 1420, a cylinder 1430, a front head 1450, a long bolt 1402, a washer 1403, a nut 1401, have.

For example, the long bolt 1402 can be inserted into the insertion hole 1420-1 formed in the head cap 1420, the cylinder 1430 and the front head 1450. [ The long bolt 1402 can fix the head cap 1420, the cylinder 1430, and the front head 1450. The long bolt 1402 can fix the head cap 1420, the cylinder 1430 and the front head 1450 by the nut 1401. The nut 1401 may be screwed to the threads formed at both ends of the long bolt 1402.

For example, the washer 1403 may be disposed between the long bolt 1402 and the nut 1401. The washer 1403 may be disposed only on the upper end of the head cap 1420. The washer 1403 may be disposed only at the lower end of the head cap 1420. The washer 1403 may be disposed at an upper end portion and a lower end portion of the head cap 1420.

For example, the long bolt 1402 may form an accommodation space 1402-4 in which the detection sensor 150 may be disposed. The accommodation space 1402-4 may be formed in the long bolt 1402 in the longitudinal direction of the rotation axis A of the long bolt 1402. The accommodation space 1402-4 may be formed entirely in the long bolt 1402. [ The center of rotation of the accommodation space 1402-4 may coincide with the center of rotation of the long bolt 1402. The upper side of the long bolt 1402 and the lower side outer side of the long bolt 1402 may be connected by the receiving space 1402-4.

For example, the long bolt 1402 includes a first head 1402-1 to which the nut 1401 is coupled, a body portion 1402-1 extending downward in the longitudinal direction from the first head 1402-1, And a second head portion 1402-3 extending downward from the first body portion 1402-2 in the longitudinal direction and coupled with the nut 1401, May be formed from the end of the first head 1402-1 to the end of the second head 1402-3.

For example, the sensing sensor 150 is inserted into the receiving space 1402-4 so that the first head 1402-1, the body 1402-2, and the second head 1402-3, It is possible to detect the breakage of the battery. The body of the detection sensor 150 may be disposed in the accommodation space 1402-4. The terminal 150-1 of the sensing sensor 150 may be formed outside the accommodation space 1402-4. However, the present invention is not limited thereto, and the terminal 150-1 may be formed in the receiving space 1402-4.

For example, the detection sensor 150 may be configured to block the openings on both sides of the accommodation space 1402-4 with a plug (not shown) made of PVC or urethane, insert the sensing sensor 150 into the groove formed in the plug So that the detection sensor 150 can be fixed without being shaken. However, the present invention is not limited thereto, and may include any means capable of fixing the detection sensor 150 to the accommodation space 1402-4.

As shown in FIG. 6, for example, the breaker 1000 may include a washer 1403.

The washer 1403 includes an inner space 1403-1 in which the long bolt 1402 is inserted, an inner surface 1403-2 defining the inner space 1403-1, and a shape of the washer 1403 And an outer surface 1403-3 defining the outer surface 1403-3.

For example, the washer 1403 can prevent the nut 1401, the head cap 1420, and the front head 1450 from being damaged, and the vibration of the breaker 1000 can be reduced.

As shown in FIG. 7, for example, the breaker 1000 may include a long bolt 1402 having a receiving space 1402-4.

For example, the long bolt 1402 may include a first head 1402-1 threaded and threaded with the nut 1402, a second head 1402-1 threaded and threadably engaged with the nut 1401, And a body portion 1402-2 for connecting the first head portion 1402-1 and the second head portion 1402-3.

At this time, the first head 1402-1 may be disposed in the upper direction with respect to the body 1402-2. The second head 1402-3 may be disposed in a downward direction with respect to the body 1402-2.

At this time, the first head 1402-1, the second head 1402-3, and the body 1402-2 may be integrally formed. The rotation centers of the first head 1402-1, the second head 1402-3, and the body 1402-2 may be aligned in the longitudinal direction.

The first head portion 1402-1 has a first head top surface 1402-1a formed with threads and screwed to the nut 1401 and a first head bottom surface 1402 inserted into the washer 1403. [ -1b).

The second head portion 1402-3 has a third head upper end surface 1402-1c formed with threads and screwed to the nut 1401 and a fourth head lower end surface Quot;). The second head portion 1402-3 may be provided only with the third head top surface 1402-1c.

For example, the body portion 1402-2 may have a body outer surface 1402-2a that defines the shape of the outer shape.

For example, the accommodation space 1402-4 may be formed longitudinally in both the first head 1402-1, the body 1402-2, and the second head 1402-3.

As shown in Fig. 8, the receiving space 2402-4 of the long bolt 1402 can be formed in another embodiment.

For example, the accommodation space 2402-4 may be formed from the end of the second head portion 1402-3 to the middle of the first head portion 1402-1.

At this time, the accommodation space 2402-4 may be formed so as to include a portion where the long bolt 1402 is severely damaged.

At this time, the terminal 150-1 of the sensing sensor 150 may be formed only toward the end of the second head 1402-3.

At this time, the body 150-2b of the detection sensor 150 may be inserted into the accommodation space 2402-4. The terminal 150-3 of the sensing sensor 150 may be disposed outside the accommodation space 2402-4, but may be disposed in the accommodation space 2402-4.

The receiving space 2402-4 is formed only up to the end of the first head 1402-1 so that moisture and foreign matter flow into the receiving space 2402-4 from the upper direction of the long bolt 1402 Can be prevented.

As shown in Fig. 9, the accommodating space 3402-4 of the elongated bolt 1402 can be formed in another embodiment.

For example, the accommodation space 3402-4 may be formed from the end of the first head portion 1402-1 to the middle of the first head portion 1402-1.

The accommodating space 3402-4 is formed so as to include the second through hole 3403-4 of the washer 3403 in a virtual direction orthogonal to the rotational axis A of the long bolt 1402 .

The receiving space 3402-4 may be formed to include a through hole (not shown) formed in the nut 1401 in a virtual direction perpendicular to the rotational axis A of the long bolt 1402 .

At this time, if the accommodation space 3402-4 is formed up to the middle of the first head portion 1402-1, the accommodation space 3402-4 can be variously modified at a level that is obvious to a general technician.

By forming the accommodating space 3402-4 only in a part of the long bolt 1402, the durability of the long bolt 1402 can be enhanced.

For example, the first head 1402-1 has a first through hole 3402-5 that connects the outside with the receiving space 3402-4, and the washer 3403 has a through- And a second through hole 3403-4 connecting the space 1403-1.

At this time, the second through holes 3403-4 may be disposed corresponding to the first through holes 3402-5.

For example, the detection sensor 150 may be inserted into the accommodation space 3402-4 to detect breakage of the first head 1402-1.

At this time, the detection sensor 150 is inserted into the first through hole 3402-5 and the second through hole 3403-4 to detect the breakage of the first head 1402-1 .

At this time, the terminal 150-1 of the sensing sensor 150 may be disposed at both ends of the body 150-2c and may be disposed at a lower side of the body 150-2c. This can be changed at a level that is obvious to a person skilled in the art in consideration of the purpose of the user and the industrial field.

At this time, the terminal 150-1 of the sensing sensor 150 may be disposed outside the accommodation space 3402-4. Also, the terminal 150-1 of the sensing sensor 150 may be disposed in the accommodation space 3402-4.

When the nut 1401 is screwed into the long bolt 1402, the first through hole 3402-5 and the second through hole 3403-4 are coupled to each other through the washer 3403, And a first corresponding means 3403-5 for correspondingly arranging them.

When the nut 1401 is screwed into the long bolt 1402, the head cap 3420 is inserted into the first through hole 3402-5 and the second through hole 3403-4, And a second corresponding means 3420-2 for allowing the first and second receiving means to be disposed correspondingly.

For example, the first through hole 3402-5 and the second through hole 3403-4 are in contact with the first corresponding means 3403-5 and the second corresponding means 3420-2 As shown in FIG.

As shown in FIG. 10, for example, the washer 3403 may further include a second through hole 3403-4 and a first corresponding means 3403-5.

For example, the second through-hole 3403-4 may connect the outer space with the inner space 1403-1 of the washer 3403.

The second through hole 3403-4 may be formed to connect the inner surface 1403-2 of the washer 3403 and the outer surface 1403-3 of the washer 3403.

The second through hole 3403-4 may be formed so as to be a center of rotation about an imaginary line orthogonal to the rotation axis A of the inner space 1403-1 of the washer 3403, And may be variously modified so that the electric wire 150-3 can be inserted into the second through hole 3403-4 at a level that is easily known to the ordinary artisan.

At this time, electric wires can be inserted into the second through holes 3403-4.

In one example, the first corresponding means 3403-5 may be formed at the lower end of the washer 3403.

At this time, the first corresponding means 3403-5 may be formed to be protruded, and may be formed by embedding.

At this time, the first corresponding means 3403-5 may have the same shape as the second corresponding means 3420-2 so as to be able to engage with the second corresponding means 3420-2.

At this time, the shape of the first corresponding means 3403-5 can be variously modified. The shape of the first corresponding means 3403-5 may include any shape such that the first through-hole 3402-5 and the second through-hole 3403-4 are correspondingly arranged.

For example, the first corresponding means 3403-5 may be formed in the washer 3403 in plural. The number of the first corresponding means may correspond to the number of the second corresponding means 3420-2. The number of the first corresponding means 3403-5 can be variously changed in consideration of an industrial environment and a manufacturing environment at a level that is obvious to a person skilled in the art.

In one example, the first countermeasure means 3403-5 may be formed to extend from the lower end of the outer surface 1403-3 to completely cover the upper end surface of the head cap 3420. [

At this time, the washers 3403 inserted into the respective long bolts 1402 may be integrally formed by the first corresponding means 3403-5.

As shown in Fig. 11, for example, the head cap 3420 may further include an insertion hole 1420-1 and a second corresponding means 3420-2 in which a long bolt 1402 is inserted.

In one example, the insertion hole 1420-1 can be formed such that the elongated bolt 1402 can be inserted.

At this time, the insertion hole 1420-1 may be formed corresponding to the shape of the long bolt 1402. [

In one example, the second corresponding means 3420-2 may be formed at the upper end of the head cap 3420. [

At this time, the second countermeasure means 3420-2 may be formed to protrude, and may be formed by embedding.

At this time, the second corresponding means 3420-2 may have the same shape as the first corresponding means 3403-5 so as to be coupled to the first corresponding means 3403-5.

At this time, the shape of the second corresponding means 3420-2 can be variously modified. In addition, the shape of the second corresponding means 3420-2 may include any shape that allows the first through holes 3402-5 and the second through holes 3403-4 to be disposed in a corresponding manner have.

For example, the second corresponding means 3420-2 may be formed in the head cap 3420 in plural. The number of the second corresponding means 3420-2 may be formed corresponding to the number of the first corresponding means 3403-5. The number of the second response means 3420-2 can be variously changed in consideration of the industrial environment and the production environment at a level that is obvious to those skilled in the art.

12, for example, the long bolt 1402 may further include a first through hole 3402-5, and the receiving space 3402-4 may include the first head 1402-1 To the middle of the first head portion 1402-1.

For example, the first through hole 3402-5 may be formed to connect the lower end surface of the first head portion 1402-1 to the receiving space 3402-4.

At this time, the first through hole 3402-5 may be formed around an imaginary line orthogonal to the rotational axis A of the elongated bolt 1402, but the present invention is not limited thereto, So that the electric wire 150-3 can be inserted into the first through hole 3402-5.

At this time, the electric wire of the detection sensor 150 is inserted into the first through hole 3402-5 and can be electrically contacted with the body 150-2c inserted into the accommodation space 3402-4.

For example, the accommodation space 3402-4 may be formed in a part of the long bolt 1402 in the lengthwise direction thereof to enhance the durability of the long bolt 1402. [

As shown in Fig. 13, as an example, the receiving space 4402-4 of the long bolt 1402 can be formed in another embodiment.

For example, the head cap 4420 may have a third through hole 4420-3 connecting the first through hole 4402-5 with the outside.

At this time, the third through holes 4420-3 may be arranged to correspond to the first through holes 4402-5.

At this time, the third through hole 4420-3 can connect the outside with the accommodation space 4402-4 through the first through hole 4402-5.

For example, the third through hole 4420-3 can connect the outside with the insertion hole 1420-1 of the head cap 4420.

At this time, the third through hole 4420-3 may be formed to connect the outer wall of the head and the insertion hole 1420-1.

The third through hole 4420-3 may be formed to connect the outer cylinder wall (not shown) or the front head outer wall (not shown) and the insertion hole 1420-1.

For example, the accommodation space 4402-4 may be formed to include the third through hole 4420-3 in a virtual direction orthogonal to the rotation axis A of the long bolt 1402. [

At this time, the durability of the long bolt 1402 can be enhanced by forming the receiving space 4402-4 only in a part of the long bolt 1402. [

For example, the detection sensor 150 may be inserted into the first through hole 4402-5 and the third through hole 4420-3 to detect breakage of the long bolt 1402. [

At this time, the body 150-2c inserted into the receiving space 4402-4 by inserting the electric wire of the detection sensor 150 into the third through hole 4420-3 and the first through hole 4402-5, It can be electrically contacted.

As shown in FIG. 14, for example, the head cap 4420 may further include a third through hole 4420-3 connecting the outside with the insertion hole 1420-1.

For example, the third through hole 4420-3 may be formed to connect the insertion hole 1420-1 through which the elongated bolt 1402 is inserted from the outer surface of the head of the head cap 4420. [

At this time, the third through hole 4420-3 may be formed around an imaginary line orthogonal to the rotational axis A of the long bolt 1402, but the present invention is not limited thereto, So that the wire 150-3 can be inserted into the third through hole 4420-3.

Hereinafter, the breakage monitoring system of the long bolt 1402 for monitoring the breakage of the long bolt 1402 using the detection sensor 150 and the controller 180 will be described in more detail.

The long bolt 1402 monitoring system may include a sensing sensor 150 and a controller 180.

For example, the controller 180 can determine whether the long bolt 1402 is broken using the breakage information detected by the detection sensor 150. [

Here, the damage information may be the amount of current flowing through the body 150-2 of the sensing sensor 150 or the resistance of the body 150-2.

The damage information may be position information detected by the position displacement receiving unit.

In addition, the breakage information may be information that the leakage sensor detects fluid.

Here, the damage information may be all the information sensed by the sensing sensor 150.

Here, the damage information may be data calculated / processed by the controller 180 on the basis of data or damage information related to the damage information sensed by the sensing sensor 150.

For example, if the predetermined condition is satisfied based on the damage information detected by the detection sensor 150, the controller 180 may determine that the long bolt 1402 is broken and perform a warning operation.

For example, the controller 180 is an electronic circuit that plays a role of processing and computing various electronic signals. The controller 180 receives breakdown information or signals from the detection sensor 150, computes information / data, Lt; RTI ID = 0.0 > 1000 < / RTI >

The controller 180 is typically located on the carrier 120, but may be located on the breaker 1000.

Also, the controller 180 does not necessarily have to be implemented as a single object.

In some cases, the controller 180 may be implemented with a plurality of controllers 180 that are capable of communicating with each other.

For example, the controller 180 may be disposed in a distributed manner such that a part of the controller 180 is disposed on the side of the breaker 1000 and a part of the controller 180 is installed on the carrier 120, It is possible to perform the function by performing wired communication and collaborating.

For example, when a plurality of controllers 180 are distributed and arranged, some of the controllers 180 may simply transmit signals or information in a slave type, while others may receive various signals or information in a master type to perform processing / Control may be performed.

The predetermined condition may be a reference condition for judging whether or not the long bolt 1402 is broken.

For example, the controller 180 may determine that the elongated bolt 1402 is broken if the computed / transformed data satisfies a predetermined condition based on the sensed information sensed by the sensing sensor 150, If the condition is not satisfied, it can be determined that the long bolt 1402 is not broken.

The predetermined condition may be set by the user and the damage information obtained from the detection sensor 150 in a normal state in which the long bolt 1402 is not damaged or the long bolt 1402 is broken, As shown in FIG.

Also, the long bolt 1402 breakage monitoring system may further include an output module for outputting image or voice.

The output module may be implemented by, for example, a video output module for outputting a video image or a voice output module for outputting audio.

Of course, various output devices that convey information to the user besides the two can be employed as the output module 190.

The output module may directly output video or audio to the user, or may include a USB port for transmitting video / audio signals to another device that directly outputs video or audio to the user.

The output module may be configured to output a video or voice and output a warning message to the user about the occurrence of the breakage of the long bolt 1402. [

In one example, the output module may be installed in the breaker 1000 or in the carrier 120.

In one example, the controller 180 may control the output module to output a warning message to the user about the occurrence of the breakage of the bolt 1402 through the output module.

The controller 180 and the output module may be capable of wired communication or wireless communication.

For example, the sensing sensor 150 may sense an amount of current flowing through the body 150-2 of the sensing sensor 150. [ The controller 180 may determine that the long bolt 1402 is broken when the breakage information (current amount) detected by the detection sensor 150 is less than a predetermined reference value.

Here, when the body 150-2 is broken due to the breakage of the long bolt 1402, current does not continuously flow through the body 150-2. In such an electrical short circuit, the amount of current flowing through the body 150-2 corresponds to '0', but a minute current may flow through the body 150-2 due to foreign substances and other experimental errors.

The predetermined condition may be a condition that the amount of change of the damage information detected by the detection sensor 150 is equal to or greater than a predetermined reference change value X.

For example, when the body 150-2 of the sensing sensor 150 is damaged, damage information of the sensing sensor 150 may be detected as damage information that is different from the previously measured damage information. Noise may be generated in the breakage information due to vibration of the breaker 1000. In order to prevent the controller 180 from determining that the long bolt 1402 is damaged due to the noise of the breakage information, the predetermined condition is that the change amount of the breakage information detected by the detection sensor 150 is smaller than a predetermined reference change (X) or more.

For example, as shown in Fig. 15, the damage information measured between t1 and t2 is smaller than the reference change value X. In this case, the controller 180 may not judge that the long bolt 1402 is broken. However, the damage information measured between t3 and t4 is larger than the reference change value (X). In this case, the controller 180 may determine that the long bolt 1402 is broken.

The long bolt 1402 breakage monitoring system may further include a vibration sensor 200 for detecting vibration information of the breaker 1000 so as to detect the vibration amount of the breaker 1000.

The vibration sensor 200 may be installed in the breaker 1000, and may be installed in the head cap 1420, for example.

The vibration sensor 200 can sense vibrational information on the vibration of the breaker 1000 generated due to the reciprocating movement of the piston and / or the striking of the striking object.

When the long bolt 1402 is broken, the tight coupling between the cylinder 1430 and the front head 1450 and the head cap 1420 is loosened, so that the vibration can be amplified rather than when the long bolt 1402 is not broken.

Power must be continuously applied to operate the detection sensor 150. [ Therefore, the detection sensor 150 can detect the breakage of the long bolt 1402 when the vibration transmission sensed by the vibration sensor 200 satisfies a predetermined vibration condition.

Since only one vibration sensor 200 is normally used, it is possible to reduce the power consumption that occurs while using the sensor.

The controller 180 may determine that the long bolt 1402 is broken if the predetermined condition is satisfied.

The long bolt 1402 breakage monitoring system may further include an output module for outputting video or audio.

Here, if the controller 180 determines that the long bolt 1402 is broken, the controller 180 may output a warning message to the user through the output module.

In addition, for example, when the controller 180 determines that the controller 180 is broken, the piston 180 can stop the reciprocating motion of the piston.

For example, the controller 180 may control the shutoff valve 1480 to shut off the flow of hydraulic fluid if the shutoff valve 1480 determines that the nut 1401 is released.

In one example, if controller 180 does not control shutoff valve 1480, shutoff valve 1480 is in the engaged position and if shutoff valve 1480 controls shutoff valve 1480, Can be changed from the connecting position to the blocking position.

That is, the controller 180 can control the shutoff valve 1480 to change from the connection position to the shutoff position, so that the shutoff valve 1480 can shut off the flow of the operating fluid.

As described above, when the shutoff valve 1480 is switched from the connection position to the shutoff position under the control of the controller 180, the control valve 1460 is continuously maintained in the backward position, and as a result, the hydraulic source 160 Can not flow into the rear chamber 1432, so that the reciprocating motion of the piston 1440 may not be realized.

The controller 180 controls the hydraulic source 160 so that the hydraulic source 160 supplies the hydraulic oil to the breaker 1000 and the hydraulic oil 160 supplies the hydraulic oil 160 to the breaker 1000. [ It is possible to control the off state to the OFF state.

That is, when the controller 180 determines that a scratch has occurred, the controller 180 may control the hydraulic source 160 so that the hydraulic oil is not supplied to the breaker 1000.

For example, the controller 180 may control the shift valve 1470 to control the reciprocating movement of the piston 1440 when it determines that the nut 1401 is released.

The controller 180 may control the shift valve 1470 to control the piston 1440 to change to the short stroke state when the piston 1440 determines that the nut 1401 has been released in the long stroke state And can stop the piston 1440 by controlling the shutoff valve 1480 when the piston 1440 determines that the nut 1401 has been released in the short stroke state.

The controller 180 may sequentially control the speed change valve 1470 and the shutoff valve 1480 so that the piston 1440 sequentially shifts to the short stroke when the piston 1440 is a long stroke and stops again at the short stroke.

The user can recognize that the nut 1401 has been released by changing the reciprocating state of the piston 1440 under the control of the controller 180. [

For example, the warning action of the controller 180 may mean outputting a warning message to the user via the output module 190 and / or changing the reciprocating state of the piston 1440. [

Hereinafter, a method of monitoring the breakage of the long bolt 1402 will be described.

The long bolt 1402 breakage monitoring method includes a step in which the chisel 1600 hits the object in accordance with the reciprocating motion of the piston 1440 in the cylinder 1430, the step of detecting breakage of the long bolt 1402, 180 may be determined that the long bolt 1402 is damaged when the predetermined condition is satisfied based on the damage information detected by the detection sensor 150, and performing a warning operation.

The controller 180 and the sensing sensor 150, the vibration sensor 200, the shutoff valve 1480, the speed change valve 1470, and the output module (not shown) to implement the technical idea of the present invention, 190 are capable of wired communication or wireless communication and are connected to the sensing sensor 150, the vibration sensor 200, the shutoff valve 1480, the speed change valve 1470, and the output module 190 under the control of the controller 180. [ Can be controlled.

Alternatively, the controller 180 may be inputted with a predetermined reference, a predetermined reference value, and a predetermined reference change value X, and the controller 180 may determine that the breakage information and / or the breakage information acquired in a normal state in which the long bolt 1402 is not broken, And may be set based on the damage information obtained in the state where the bolt 1402 is broken.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
