Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a wall surface inspection device, and more particularly, a crack condition (width and depth) in a vertical or inclined wall surface of a building made of mortar or tiles, or a crack condition between tiles. This invention relates to a device for visually inspecting the condition of joints and caulking.

When such inspections are performed with the naked eye from the ground using a telescope or telephoto camera, the high parts of the wall are viewed diagonally from below, making it very difficult to see the condition (width and length of the crack). The drawback is that it is difficult. On the other hand, constructing scaffolding or using gondolas to inspect the wall surface from nearby would not only require an extremely large number of man-hours, increase costs, and take a long time to conduct the inspection, but it would also be dangerous. Another drawback is that some areas cannot be inspected depending on the location.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to eliminate the need for scaffolding or gondolas, even on walls that include high places or dangerous areas that cannot be directly approached by people. It is an object of the present invention to provide a device that can accurately inspect the condition of a wall surface from any location away from the wall surface in a short time and at low cost.

In order to achieve the above object, the wall inspection device according to the present invention has a wall photographing mechanism mounted on a vehicle body that can travel while adhering to a wall, and can monitor images taken by the photographing mechanism at any location. It has the following characteristics:

The functions and effects exhibited by this characteristic configuration are as follows.

That is, for example, a mechanism for photographing the wall surface is mounted on a vehicle body that can be moved to any location on the wall surface by remote control, and the resulting image of the wall surface can be displayed on a monitor TV at any location, such as on the ground. This allows you to check the condition of cracks, joints, and caulking on walls at any time and at your convenience, just as if you were looking at them from a close distance. Furthermore, by installing monitor televisions and the like, it has become possible for multiple people, including not only the person in charge of the construction work but also the client, to visually check the inspection results at the same time. In addition, even if the wall surface includes small parts that people cannot directly approach or dangerous high places, the vehicle body can be moved arbitrarily to remove such small parts or high places without using scaffolding or gondolas. Since inspection of specific parts can be easily carried out, it has become possible to inspect the condition of wall surfaces very safely, in a short period of time, and at low cost.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.As schematically shown in FIG. At the same time, there is a vehicle body (C) that can run while adhering to a wall (B), and a control section and equipment group (R) on the ground, for example.

This system constitutes a system that can be operated at a control unit (R) located at an arbitrary location apart from the wall (B).

There is a monitor TV that displays the captured images.

The specific details of the vehicle body (C), the wall photographing mechanism attached thereto), and the tile peeling detection mechanism (B) are as shown in FIG.

That is, the vehicle body (C) is attached to the lower part of the vehicle body frame (5) via a fixed frame (6) with elongated holes, and bolts (7)... A cross-sectional annular frame (8) is attached so as to be changeable, and a skirt portion side (9) made of an elastic material such as rubber is attached from this frame (8).

Further, a crawler-type traveling device 4 is installed in the interior space (S), so that the crawler drive device O; 1 can be operated. Note that the frame (8)
By adjusting the perspective position relative to the vehicle body frame (5),
By adjusting the degree of adhesion of the lower end edge of the skirt member (9) to the wall surface (A), the suction force can be adjusted according to the condition of the wall surface (A). This has already been proposed by the applicant of the present application in a patent application filed on December 28, 1980. The tile peeling detection mechanism (B) is installed on the vehicle body (C).

That is, the tile peeling state is detected from the characteristic vibration that occurs when the tile is peeling off.The display device (2) of the control section (R) includes a speaker and A detection indicator lamp is provided. Further, although not shown, a wire suspended from the roof is connected to the vehicle body (C) via a fall prevention device, so as to prevent an accidental fall due to a decrease in suction force.

The wall photographing device (A) includes a video camera μQ fixed to the front part of the upper surface of the vehicle body frame (5), and a mirror ( 17), and the angle of the mirror Uη with respect to the wall surface (B) is adjusted eight-dimensionally so that the range of the wall surface (B) corresponding to the wall image reflected toward the camera 4 can be changed within a certain range. It consists of four mirror drive devices w that can be changed to some extent. This mirror drive device H, (L

The vehicle body (C ) has the advantage of reducing the frequency of travel control and travel stop control operations.

In the above embodiment, the wall photographing mechanism (A) is constructed by combining the camera aCt and the mirror Qη, but it may be configured to directly photograph the wall using only the camera. In that case, the camera itself may be configured to be able to change its angle eight-dimensionally.

Alternatively, a still photo production device may be connected to the monitor television (4).

Furthermore, if the decompression space (S) is divided into a plurality of sections to reduce the effect of air escaping from the lower edge of the skirt (9), even when the joint thickness is large, etc. , it is not necessary to increase the capacity of the exhaust fan Oυ so much, and it is economical.
