As shown in FIGS. 1 and 2, the wall surface inspection device is formed in a rectangular shape (square) by the upper frame 11, the lower frame 12, and the left and right frames 13, 13 and has a frame main body 10 having a rectangular opening in the center and a frame. A consultation unit 20 that consults or slides on the wall surface H provided on the lower frame 12 of the main body 10, main body suspension portions 14 and 14 provided on the left and right ends of the upper frame 11 of the frame main body 10, and a frame main body 10. The sound collecting microphone 16 provided in the center of the upper frame 11, the weight suspension lower parts 17 and 17 provided on the left and right ends of the upper frame 11 of the frame body 10 in multiple stages in a horizontally expandable manner, and the frame body 10 It is composed of four wheels 15 rotatably provided on the upper and lower sides of the left and right frames 13 and 13. As the material of the upper frame 11, the lower frame 12, and the left and right frames 13, 13, a durable steel plate or the like is preferably used.

Although the details of the percussion unit 20 provided in the lower frame 12 of the frame body 10 will be described later, the wall surface for inspecting the percussion balls 21a provided at the tip of the wall surface H side of a plurality of (9 in this embodiment) percussion rods 21. It has a mechanism that can generate wall surface inspection data (percussion sound or sliding sound) by consulting and sliding on H.

The main body suspension portions 14, 14 provided at the upper left and right ends of the upper frame 11 of the frame main body 10, respectively, are formed in a ring shape so that one end of the wire rope R can be fastened. Then, as shown in FIG. 6, one end of the wire rope R is fastened to the main body suspension lower portions 14 and 14, and the other end of the wire rope R is wound or unwound by the winding machine 30 installed on the roof of the building. Therefore, the frame body 10 can be moved in the vertical direction of the wall surface H of the building.

The four wheels 15 rotatably provided on the left and right sides of the frame 13 and 13 of the frame body 10 are assumed to be fanned by the weather (mainly wind) when the frame body 10 moves up and down on the wall surface H. Also, the direct contact between the frame body 10 and the wall surface H is restricted to prevent the wall surface H and the frame body 10 from being damaged. The two wheels 15 provided on the lower left and right sides of the left and right frames 13 and 13 have a wall surface of the percussion ball 21a at the tip of the percussion rod 21 constituting the percussion unit 20 described later, rather than the outer peripheral portion of the wheel 15. It protrudes to the H side. Therefore, it is possible to maintain the contact between the percussion ball 21a and the wall surface H below the frame body 10.

The sound collecting microphone 16 provided in the central portion of the upper frame 11 of the frame body 10 is generated when the wall surface H for inspecting the percussion ball 21a at the tip of the percussion rod 21 on the wall surface H side is consulted or slid. The purpose is to collect sounds (that is, wall surface inspection data composed of percussion sounds or sliding sounds of the wall surface H by the percussion ball 21a). The diagnosis of the wall surface inspection data at the time of wall surface inspection in the present embodiment can be made by inputting the wall surface inspection data from the sound collecting microphone 16 into a personal computer (personal computer) in which dedicated analysis software is installed. .. Further, a skilled worker can directly hear the wall surface inspection data from the sound collecting microphone 16 to diagnose the abnormality of the wall surface H. In this way, by providing the sound collecting microphone 16 at the center of the upper frame 11, the percussion balls 21a at the tips of a plurality of (9 in this embodiment) percussion rods 21 can be consulted or slid on the wall surface H to be inspected. The wall surface inspection data (percussion sound or sliding sound) obtained by moving is configured to be efficiently collected without being obstructed through the rectangular opening formed in the center of the frame main body 10.

As shown in FIGS. 1 and 5, the weight hanging lower portions 17 and 17 provided on the left and right end side surfaces of the upper frame 11 of the frame main body 10, respectively, have the base ends on the left and right end side surfaces of the upper frame 11 on the side opposite to the wall surface H. The lower end 17a of the weight suspension at the tip is stretchable in multiple stages (for example, 3 stages) in the horizontal direction. The lower end 17a of the weight suspension is formed in a ring shape, and a weight W having a predetermined weight is suspended. One end of the wire rope R is fastened to the upper portion of the weight W, and a hook F for locking the weight W to the lower end of the weight suspension 17a is provided at the other end. Then, the weight W is suspended by hooking the hook F on the weight suspension lower end 17a of the weight suspension lower portion 17. In the present embodiment, since a plurality of weights W having different weights are prepared in advance for the weights W suspended from the weight suspension lower end 17a of the weight suspension lower portion 17, a hook F can be easily attached to the weight suspension lower end 17a of the weight suspension lower portion 17. It can be attached and detached. As the hook F, for example, a hook provided with a retaining metal fitting that can lock the locked state, although it is easy to attach / detach to the ring-shaped weight hanging lower end 17a, is preferably used.

By configuring the weight W to be suspended from the weight suspension lower end 17a of the weight suspension lower portion 17 in this way, as shown in FIG. 5A, when the weight W is not suspended, it is designated as the wall surface H. The frame main body 10 is vertically suspended by the main body hanging lower portions 14 and 14 at intervals. On the other hand, as shown in FIG. 5B, when the weight W is suspended from the weight suspension lower end 17a of the weight suspension lower portion 17, the load of the weight W (black arrow in the figure) is applied to the frame body 10. The upper frame 11 tilts in a direction away from the wall surface H with the main body suspension lower portions 14 and 14 as the center. On the other hand, the lower frame 12 is tilted in a direction approaching the wall surface H, and the percussion balls 21a at the tips of the plurality of percussion portions 20 (nine in the present embodiment) on the wall surface H side of the percussion portions 20 provided on the lower frame 12 , It will be pressed against the wall surface H (white arrow in the figure) with a predetermined pressure.

As described above, in the present embodiment, the horizontal length of the weight suspension lower portion 17 and the weight suspended from the weight suspension lower end 17a of the weight suspension lower portion 17 in response to changes in the weather (mainly wind force) at the inspection site. By changing the weight of W, the pressing force between the percussion unit 20 (the percussion ball 21a at the tip of the percussion rod 21 on the wall surface H side) and the wall surface H of the building can be easily adjusted. Specifically, when a strong wind is blowing around the wall surface H, the weight suspension lower end 17a of the weight suspension lower portion 17 is extended to the maximum length, and the heaviest weight W is suspended from the weight suspension lower end 17a. Increases the pressing force between the percussion unit 20 (the percussion ball 21a at the tip of the percussion rod 21 on the wall surface H side) and the wall surface H of the building to prevent the percussion unit 20 from being agitated by a strong wind and separating from the wall surface H. And the wall surface H can be reliably inspected.

Hereinafter, the configuration and operation of the percussion unit 20 in the present embodiment will be described with reference to FIGS. 3 to 5. The consultation unit 20 is arranged on the wall surface side of the lower frame 12 of the frame main body 10, and a plurality of (9 in this embodiment) consultation rods 21 are installed on the mounting frame 25 at equal intervals. The consultation rod 21 is between the spherical consultation ball 21a at the tip on the wall surface H side, the washer 21b at the rear end, the fixing portion 21d for fixing the consultation rod 21 to the mounting frame 25, and the consultation ball 21a and the fixing portion 21d. It is composed of a coil spring 21c arranged. SUS (stainless steel) is preferably used as the material of the percussion rod 21, and the diameter of the percussion ball 21a is preferably about 20 mm.

The drive unit of the consultation unit 20 is composed of a motor M and an aluminum rod 22 rotatably connected by the motor M. A disk-shaped set collar 23 is fixed to the aluminum rod 22 at predetermined equal intervals, and hook pins 24 are radially extended from the center of the set collar 23 on the outer circumference of the set collar 23. The tip of the hook pin 24 is covered with a protective cover 24a made of resin.

With the above configuration, the aluminum rod 22 rotates according to the rotation of the motor M, and the set collar 23 fixed to the aluminum rod 22 at predetermined equal intervals rotates. As a result, as shown in FIG. 4, the tip (protective cover 24a) of the hook pin 24 provided on the outer periphery of the set collar 23 comes into contact with the washer 21b provided at the rear end of the consultation rod 21 and horizontally touches the wall surface. The consultation rod 21 is moved in the direction away from H. As a result, the coil spring 21c disposed between the percussion ball 21a of the percussion rod 21 and the fixing portion 21d is compressed (FIG. 4B).

Further, when the protective cover 24a of the hook pin 24 provided on the outer periphery of the rotating set collar 23 and the washer 21b provided at the rear end of the consultation rod 21 progress, the protective cover 24a and the washer 21b are abbreviated. The consultation rod 21 is moved horizontally to the position farthest from the wall surface H by making contact at an angle of 30 degrees. As a result, the coil spring 21c disposed between the percussion ball 21a and the fixing portion 21d of the percussion rod 21 is maximally compressed (FIG. 4 (c)).

Further, when the set collar 23 rotates, the contact between the protective cover 24a and the washer 21b is released, so that the percussion ball 21a at the tip of the percussion rod 21 on the wall surface H side is released from the compression of the coil spring 21c and is moved to the wall surface H side. A percussion sound is generated when the percussion ball 21a and the wall surface H collide with each other.

The hook pins 24 provided on the outer circumference of the disk-shaped set collar 23 fixed to the aluminum rod 22 are set on the outer circumference of each set collar 23 so as to have different phases (approximately 30 degrees) in the rotational direction. Each is extended on the outer circumference of the collar 23. That is, the above-mentioned contact between the protective cover 24a at the tip of the hook pin 24 and the washer 21b at the rear end of the consultation rod 21 due to the rotation of the set collar 23 and the release of the contact are timed for each of the nine consultation rods 21. It has a staggered configuration. This makes it possible for the sound collecting microphone 16 to collect the percussion sounds generated by the collisions between the percussion balls 21a of the nine percussion rods 21 and the wall surface H at different timings without overlapping.

Further, when collecting the sliding sound between the percussion ball 21a of the percussion rod 21 and the wall surface H, the protective cover 24a at the tip of the hook pin 24 due to the rotation of all the set collars 23 and the washer constituting the percussion rod 21. This is performed with the rotation of the motor M stopped at a position where it does not come into contact with 21b. As a result, the sliding sound between the percussion ball 21a of the percussion rod 21 and the wall surface H can be collected while the percussion ball 21a of the nine percussion rods 21 and the wall surface H are in reliable contact with each other.

Further, as shown in FIG. 7, the wall surface inspection device may be a device provided with a riding unit E on which the worker S rides.
