Description

Facility examination device

The present invention relates to an apparatus for inspecting the state (eg, cracks, damage, etc.) of auxiliary facilities applied to main facilities such as bridges, dams, tunnels, etc. It relates to a facility inspection device that can closely photograph the condition of a target facility (eg, an underground common duct or a small ventilation passage in an underpass).

In general, as well as bridges, dams, and tunnels, jet fans installed on bridges, dams, and tunnels, lighting, vehicle detection system (VDS), lane control system (LCS; Lane Control Systwm), monitoring device (CCTV) ), road electric signage (VMS), etc., deteriorate and damage over time due to natural and environmental factors, etc. Continuous and efficient inspection and diagnosis should be carried out.

Appearance investigation is the most basic investigation item in performing such inspection and diagnosis. The investigation of cracks or damage, especially during the exterior investigation, is a very important factor in evaluating the condition of the inside and outside of the facility and determining the items, procedures, and methods for performing local precise safety diagnosis in the next step.

A typical conventional external appearance inspection method for cracks or breakage is a visual inspection method by manpower. Visual inspection lacks objectivity because its results cannot be expressed quantitatively and therefore cannot be compared with other inspection results, and therefore relies on personal knowledge and experience.

In addition, since it is impossible to accurately grasp the current state as well as the history of the surrounding conditions, it cannot be compared with the past inspection results, and even experienced technicians can fix defects in invisible parts such as the inside of concrete or parts that are difficult to access by manpower. can't find

In particular, in the case of cracks or damage, it is usually impossible to obtain objective data because most of the cases are visually checked without using a measuring device that can make quantitative judgments. It is almost impossible to conduct an inspection.

Accordingly, conventionally, to measure a change in the state of a facility, as in Korean Patent Publication No. 2001-0094657, a defect in a bridge is detected through a camera-equipped rover, or in Korean Patent Publication No. 10-2008-0078167. The state change of the facility was detected by the laser scanning method as in , or the state change of the underground space was measured as in Korean Patent Application Laid-Open No. 10-2008-0045435.

However, the inspection equipment of the prior art as described above has the disadvantage of not being able to move freely, and in particular, when trying to inspect the change of state such as cracks or damage on the surface of the tunnel facility, there is a disadvantage that the measurement distance cannot be effectively adjusted. , Due to this lack of control function, the sharpness of the image through the imaging equipment was lowered, which caused considerable difficulties in the analysis.

Accordingly, the applicant of the present application, as in Patent Publication No. 10-1732085 and Patent Publication No. 10-1843947 (transfer of rights from Yangsoo Kim to Awasoft), is coupled to a vehicle to move or make self-flying movement. The facility was photographed through an imaging device and analyzed to check the state changes such as cracks or damage to the facility.

However, the facility inspection device provided in the above prior art as well as the registered patent publication of the applicant of the present application is a narrow space within the facility, and it is difficult to enter the underground common area or small ventilation passage of the underground passageway. It was not possible to closely examine the condition of cracks or breakage on the surface.

The lighting module and the photographing module 11 are seated on the seating part 10a, which is a ring-shaped structure, while the main body part 10 is the center of the inspection target facility 100. The ground surface ( 101) and the side 102 and the upper surface 103 can be taken 360 °.

Here, the lighting module, not shown, may be a conventional LED lamp or an infrared lamp, and the photographing module 11 may be any one of a conventional DSLR, Area Scan, and Line Scan. to be omitted.

The propulsion driving unit 20 is rotated in a first direction (P1) in an upward direction at the front and rear of the main body part (10), and a second direction (P2) in a downward direction opposite to the first direction (P1). It is to be coupled as possible, to provide a driving force for the driving of the main body portion 10, the driving wheel 21, the shaft rod 22, the first rotation rod 23, the second rotation rod (24) will include

The driving wheel 21 is rotated by the driving force of the first driving unit M1 as a pair, and the first driving unit M1 rotates forward or reversely on any one of the driving wheels 21 forming the pair. As the rotational driving force is transmitted, the driving wheel 21 may rotate in a forward or reverse direction to drive the main body 10 in a forward or reverse direction.

Here, although not specifically shown in the drawing, the first driving unit M1 is formed on any one of a motor that rotates forward and reverse, a driving gear connected to the motor, and a pair of the driving wheels 21 . It may include a driven gear meshed with the driving gear, and the driving wheel 21 without the driven gear may be shaft-coupled to enable free rotation.

The shaft rod 22 is rotatably coupled to the front and rear sides of the main body 10, respectively, and the rotation of the shaft rod 22 can be made according to the driving force of the second driving part M2. .

Here, although not specifically shown in the drawing, the second driving unit M2 is formed in a motor that rotates forward and reverse, a driving gear connected to the motor, and the shaft rod 22 and is gear-engaged with the driving gear It may include a driven gear.

The first rotary rod 23 is coupled and fixed to the shaft rod 22, and the first direction P1 in the upward direction as shown in FIGS. 2 to 4 attached by the rotation shaft rod 22 ) or may be configured to rotate in the second direction P2 in the downward direction as in the accompanying FIGS. 5 to 7 .

The second rotating rod 24 is the third direction P3 of accommodation as in FIGS. 2 and 5 attached for length adjustment in the first rotating rod 23 according to the driving of the third driving unit M3. Alternatively, as in FIGS. 3 and 4 and the accompanying FIGS. 6 and 7 , it moves linearly in the fourth direction P4 of withdrawal opposite to the third direction P4.

At this time, the driving wheel 21, which rotates according to the driving of the first driving unit M1, may be rotatably coupled to the second rotating rod 24, and for this purpose, the second rotating rod 24 While forming a pair of extension rods 24a facing each other at The first driving unit M1 may be connected to each other.

Here, although not specifically shown in the drawings, the third driving unit M3 may include a motor that rotates forward and reverse, a pinion gear connected to the motor, and a rack gear gear-engaged with the pinion gear.

On the other hand, each motor included in the lighting module and the shooting caps 11, as well as the first to third driving units M1, M2, M3, is on/off controlled by the remote control terminal 40 Of course, the forward rotation driving and the reverse rotation driving may be remotely controlled, and thus, a receiving unit (not shown) for receiving the remote control signal of the remote control terminal 40 may be configured in the main body 10 . .

At this time, the reason for selectively rotating the first rotational rod 23 and the second rotational rod 24 in the upward first direction P1 or the downward second direction P2 is a narrow space. This is to allow the driving wheel 21 to come into contact with the flat surface to be driven in the facility 100 to be inspected when there is only one of the upper and lower directions or both sides.

In addition, the reason for linearly moving the first rotating rod 23 to receive the second rotating rod 24 in the third direction P3, or selectively linearly moving the second rotating rod 24 to be drawn out in the fourth direction P4. is to allow the driving wheel 21 to contact the ground according to the vertical height or left and right width within the inspection target facility 100, which is a narrow space.

The traveling support part 30 is at least one formed on the bottom surface of the main body part 10, and the main body part 10 through the propulsion driving part 20 runs along the inspection target facility 100 in a narrow space. It supports the running of the main body 10, and may include a rolling roller 31, a support rod 32, and a lifting rod 33.

The rolling roller 31 is a spherical body made of a rubber material, and the support rod 32 is formed on the bottom edge side of the main body 10 , which is an elevating groove structure formed in the main body 10 . it could be

The lifting rod 33 is in the fifth direction (P5) of accommodation in the support rod 32 as shown in FIGS. 2 and 3 and the accompanying FIGS. 5 and 6 according to the driving of the fourth driving unit M4. Or by linear movement in the sixth direction (P6) of the withdrawal opposite to the fifth direction (P5) as in the accompanying FIGS. 4 and 7, one end of the lifting rod 33 is rotated in a 360° direction. To make this possible, the rolling roller 31, which is a spherical shape, may be seated.

Here, the reason for forming the rolling roller 31 as a spherical body is that when the main body 10 is driven by the driving wheel 21, the rolling roller 31 travels while in contact with the ground. This is to support the lower portion of the main body 10 , and accordingly, the main body 10 can be stably driven by the driving wheels 21 .

At this time, the rolling roller 31 is a bar that can be raised and lowered by the lifting rod 33, which is at least one or more capable of 360° shooting on the seating part 10a, which is a ring-shaped structure of the body part 10. When the photographing module 11 is seated, if the photographing module 11 disposed on the bottom side of the main body 10 is close to the ground, the photographing resolution is poor when photographing the ground by the photographing module 11 . This is to prevent breakage.

Here, although not specifically shown in the drawing, the fourth driving unit M4 may include a motor that rotates forward and reverse, a pinion gear connected to the motor, and a rack gear that is gear-engaged with the pinion gear, In addition, the motor included in the fourth driving unit M4 is turned off by the remote control terminal 40, and the forward rotation and reverse rotation driving can be remotely controlled.

In this way, the facility inspection apparatus (A) according to the embodiment of the present invention is to first put the main body portion 10 into the inspection target facility 100, which is a narrow space, as shown in the accompanying FIGS. 1 to 10 .

At this time, when the inspection target facility 100 has an inverted triangle structure as an accessory facility as in FIGS. 9 and 10 attached, the upper surface 103 of the inspection target facility 100 provides a drivable flat surface. , the operator remotely controls the second driving unit M2 through the remote control terminal 40 to rotate the shaft rod 22 formed in the front and rear of the main body 10, respectively, and the shaft rod 22 ) a first rotation rod 23 fixed to the coupling, and a second rotation rod 24 that is coupled to the first rotation rod 23 so as to be length-adjustable, as shown in FIG. 1 in the upward direction. rotate in the direction P1.

Then, the driving wheels 21 respectively rotatably coupled to the extension rods 24a formed on the second rotation rod 24 are flat upper surfaces formed in the upper direction as shown in FIGS. 9 and 10 attached thereto. (103) can be contacted.

Here, even if the first and second rotation rods 23 and 24 are rotated in the first direction P1 , when the driving wheel 21 does not contact the upper surface 103 in the upward direction, the operator can control the remote control The third driving unit M3 can be controlled to be driven through the terminal 40, and in this case, the second rotating rod 24 is attached to the first rotating rod 23 in the fourth direction as shown in FIG. 2 ( P4), the driving wheel 21 may be in contact with the upper surface 103 .

In addition, the spherical rolling roller 31 included in the traveling support 30 formed on the bottom side of the main body 10 may be in contact with the inclined side 102 .

At this time, when the rolling roller 31 cannot contact the inclined side 102 due to the height of the upper surface 103 and the ground 101 of the facility 100 to be inspected, the operator can use the remote control terminal 40 ) through the driving control of the fourth driving unit (M4), in this case, the lifting rod 33 included in the traveling support unit 30 is drawn down in the sixth direction (P6) as shown in the attached FIG. While this is made, the rolling roller 31 , which is a spherical body, can be in contact with the inclined side wall surface 102 .

Therefore, when the driving wheel 21 and the rolling roller 31 stably contact the upper surface 103 and the inclined side surface 102, respectively, as described above, the operator operates the first driving unit ( M1) is driven, and accordingly, the main body 10 can travel along the inspection target facility 100, which is a narrow space, and has a ring-shaped structure on the seating portion 10a, which is a ring-shaped structure of the main body 10, when driving. The photographing module 11 mounted as The inclined side 102, and the upper surface 103 can be photographed selectively or simultaneously, and cracks or cracks in the structural wall surfaces 101, 102, 103 through the image information photographed through the photographing module 11 or You can check for damage, etc.

On the other hand, although not shown in the drawing, the driving wheel 21 driving on the upper surface 103 constituting the structural wall surface of the inspection target facility 100 to which the body part 10 is to be inserted is impossible, and only driving on the ground 101 If possible, the operator remotely controls the second driving unit M2 through the remote control terminal 40 to rotate the shaft rod 22 formed in the front and rear of the main body 10, respectively, and the shaft rod A first rotary rod 23 coupled and fixed to (22), and a second rotary rod 24 coupled to the first rotary rod 23 so as to be length-adjustable, as shown in FIG. It rotates in the second direction P2.

Then, the driving wheels 21 respectively rotatably coupled to the extension rods 24a formed on the second rotation rod 24 may be in contact with the ground surface 101 formed in the downward direction.

Here, even when the first and second rotation rods 23 and 24 are rotated in the second direction P2, if the driving wheel 21 does not contact the ground 101 in the downward direction, the operator can remotely control The third driving unit M3 can be controlled to be driven through the terminal 40, and in this case, the second rotating rod 24 is attached to the first rotating rod 23 in the fourth direction as shown in FIG. 6 ( P4), the driving wheel 21 may be in contact with the ground 101 .

In addition, the rolling roller 31 which is a spherical body included in the traveling support 30 formed on the bottom side of the main body 10 may also be in contact with the ground 101 .

At this time, if the body portion 10 is too close to the ground 101, the photographing by the photographing module 11 cannot be properly performed, and the operator operates the fourth driving unit M4 through the remote control terminal 40. The driving control can be performed, and in this case, the lifting rod 33 included in the traveling support unit 30 is lowered to be drawn out in the sixth direction P6 as shown in the attached FIG. 7 , and the main body portion 10 is to be able to maintain a certain distance with the ground (101).

Then, as described above, when the driving wheel 21 and the rolling roller 31 are stably in contact with the ground 101, respectively, and the main body 10 is spaced a certain distance from the ground 101, the operator The first driving unit M1 is driven through the remote control terminal 40, and accordingly, the main body unit 10 can travel along the inspection target facility 100 that is a narrow space, and the main body unit 10 during the driving. The photographing module 11, which is seated as a ring-shaped structure on the receiving part 10a, which is a ring-shaped structure of 102, and the upper surface 103 can be photographed selectively or simultaneously, and cracks or damage in the structural wall surfaces 101, 102, 103 can be checked through the information photographed through the photographing module 11. it can be
