Description

Crack measurement device for safety diagnosis of facilities with easy measurement of crack information

The present invention relates to a crack measuring device for safety diagnosis of a facility that can measure crack width and crack depth and can easily measure crack information to easily inform the outside of the crack state.

In general, when a crack occurs in a facility, there is a risk that the facility may collapse depending on whether or not the crack grows.

Accordingly, a safety diagnosis is performed on the facility, and when a safety diagnosis is performed, if a crack occurs at a major location in the facility, the growth of the crack is observed.

In order to observe crack growth, the "Concrete Crack Progression Measuring Instrument" of Korean Patent Registration No. 10-0568264 (April 11, 2006) has been disclosed.

The conventional concrete crack progress meter is a crack progress meter for measuring whether the crack progresses on the concrete surface. It is adhered to one surface centering on the crack formed on the surface of the concrete structure, and has a cantilever type that crosses the crack. a body case in which the fixing part is integrally formed; a slide member that is adhered to the other side of the concrete surface around the crack and is slidably installed along the bottom surface of the fixing part; A plurality of sensor terminals that are installed at a predetermined distance apart from the tip of the bottom surface of the fixing part and are connected to light emitting devices of different colors and are installed on the upper surface of the slide member at a predetermined angle so as to sequentially contact the plurality of sensor terminals a sensor unit comprising a sensor contact plate having an inclined portion formed thereon; It is configured to include a power connection terminal and a power connection lead installed on the bottom surface of the fixing part and the top surface of the slide member so as to apply power to the sensor contact plate and the sensor terminal.

The conventional concrete crack progress meter with this configuration visually displays the change in the crack width as the crack width increases, so that it is possible to easily check the progress of the minute crack width.

However, since the conventional concrete crack progress meter measures only the growth of the crack width, it cannot measure the growth of the crack depth. There was a problem in that the maintenance cost was increased due to power consumption.

The present invention has been devised to solve the above problems, and the problem to be solved by the present invention is that it is possible to measure the growth of the crack depth by measuring the crack depth by a depth measuring unit, as well as measure the growth of the crack depth. 2 The crack width can be measured easily by measuring the width of the crack with the measuring table and the width measuring cylinder. As the crack width grows, the fluid filled in the width measuring cylinder operates the crack indicator through the hose. The purpose of this is to provide a safety diagnosis crack measuring device for facilities that can easily measure crack information that can measure crack width growth and crack width change at a location spaced from the point where this occurs.

In addition, since the progress of cracks is shown on the rotating disc of the crack indicator, even the elderly who have difficulty in measuring cracks can easily identify the growth status of crack widths and prepare for accidents such as collapse of facilities due to the growth of crack widths. An object of the present invention is to provide a safety diagnosis crack measuring device for facilities that can easily measure crack information that can reduce maintenance costs by minimizing power consumption by operating an alarm only in the state.

The gap between the support plate parts 141 is narrowed.

When the gap between the first support plate part 131 and the second support plate part 141 is narrowed, the pressing shaft of the width measuring cylinder 150 positioned between the first support plate part 131 and the second support plate part 141 ( 151) is pressurized and inserted into the pressurizing housing 155, and when the pressurizing shaft 151 is inserted, the pressurizing head 153 moves together to pressurize the fluid filled in the charging space.

The fluid pressurized in the filling space of the width measuring cylinder 150 is discharged through the discharge port 156 and flows into the inlet 172 of the operation housing 171 through the hose 160 .

At this time, the position of the pressure head 153 of the width measuring cylinder 150 may be measured through the difference between the initial position and the changed position through the scale of the width display unit 157 to measure the grown crack width.

On the other hand, when the fluid flows into the indicator cylinder 170 , the operation head 175 is pressed while the operation shaft 173 connected to the operation head 175 protrudes from the operation housing 171 and protrudes from the operation housing 171 . The actuating shaft 173 presses the actuating protrusion.

When the working protrusion is pressed, the rotating disc 181 rotates as much as the distance at which the working shaft 173 protrudes, and the gap between the first attachment part 133 and the second attachment part 143 is widened due to the continuous growth of the crack width. On the ground, as the amount of fluid supplied to the indicator cylinder 170 is increased by that amount, the protruding length of the operating shaft 173 is further increased to further rotate the rotating disk 181 .

Here, when the rotating disk 181 is rotated by the actuating shaft 173, the length at which the crack width has grown can be predicted through a scale that can estimate the rotated angle.

On the other hand, when the gap between the first attachment part 133 and the second attachment part 143 is widened to the maximum of the crack width, the operation protrusion is maximally pressed by the operation shaft 173 and the rotating disk 181 is rotated to rotate the display window. The indication of safety and the indication of danger are shown through 186 , and the operating shaft 173 presses the warning switch 187 .

When the operating shaft 173 presses the warning switch 187, the alarm 189 operates, and the alarm 189 warns of the growth of cracks externally by sound or light, indicating that the collapse of the facility may occur. It is possible to prevent the occurrence of a collapse accident of the facility by notifying the outside.

Therefore, the safety diagnosis crack measuring device 100 for a facility in which crack information can be easily measured according to an embodiment of the present invention can simultaneously measure the crack depth and crack width by the depth measuring unit 110 and the width measuring cylinder 150 . In addition, it is possible to continuously measure the growth of crack depth and crack width change.

In addition, since the width measuring cylinder 150 and the indicator cylinder 170 operating the crack indicator 180 are connected by a hose 160 and operate according to the movement of the fluid, the growth of the crack width at a point spaced from the crack is confirmed. It is possible to prevent the occurrence of accidents such as the collapse of facilities due to the growth of cracks in advance.

In addition, it is possible to easily measure whether or not the crack width has grown through the rotation angle of the rotating disc 181 of the crack indicator 180, even if the crack width is not measured at the location where the crack occurs, as well as the rotating disc 181. By looking at the crack state displayed in the figure, even the elderly can easily identify and cope with the growth of the crack width.

In addition, since the alarm 189 is operated only in a dangerous situation and electricity is not consumed until a dangerous situation does not occur, maintenance costs can be reduced.

Although the embodiment of the present invention has been described above, the scope of the present invention is not limited thereto, and it is easily changed from the embodiment of the present invention by a person skilled in the art to which the present invention belongs and recognized as equivalent. including all changes and modifications to the scope of
