Description

DETAILED DESCRIPTION OF THE INVENTION A. OBJECTS OF THE INVENTION a. Field of Industrial Application The present invention relates to an inclinometer-type block-installed shape measuring machine.

b. Conventional technology and its problems: For wave dissipation on breakwaters, which are the main structures in ports, irregularly shaped blocks are installed in random piles, and currently their finished form is managed manually by dividing them into the upper part of the water and the part below the water. It is being implemented.

Performance management by divers and workers using staff levels, etc. has limitations in terms of safety and efficiency, and is therefore insufficient. As a result, there is a mismatch with the finished form management of other structures.

B Arrangement of the Invention a Means for Solving the Problem The present invention attempts to solve the above-mentioned problem with the following arrangement. That is, the device of the present invention consists of a measuring section, a recording processing section, and a holding section, and the measuring section is a series of measuring bands with a number of links each having a universal joint at both ends, and is configured to be able to float up and down. The part is a clinometer type which is configured to be laid in contact with the wave-dissipating surface of the irregularly shaped block from a holding part arranged on the breakwater body, and is configured to display and plot the signal from the inclination sensor of the measuring part by recording processing. This is a block installation finished shape measuring machine.

b. Embodiments of the Invention A is an inclinometer-type block-installed shape measuring machine of the present invention, which is composed of a measuring section, a recording processing section, and a holding section.

The measuring section is constructed by laying and contacting the measuring section from a holding section installed on the breakwater body onto the wave-dissipating surface of the irregularly shaped block, and the signal from the tilt sensor of the measuring section is displayed and plotted by the recording processing section. This is a measuring machine that can be installed on a measuring block.

Explanation of the measurement part Figure 2 shows an inclinometer type block measuring device.

The measurement section consists of a series of measurement bands 1 by connecting a large number of links 2 each of which has universal joints 1 at both ends.
Configure 0.

The detailed structure of universal joint 1 is shown in Part 3.
As shown in the figure, the relative angle of the measurement link 2 can be detected by embedding magnetic rubber 3 in the shaft part of the bearing and attaching a tilt sensor 4, which is a magnetic sensor, to the holder part of the bearing. There is.

As shown in FIG. 2, the measurement band has a structure in which three links are connected by horizontal universal links 5 so as not to fall into the valleys of irregularly shaped blocks.

6, water is injected into the measurement part to bring it into close contact with the irregularly shaped block, and when moving to the next measurement point, air is supplied from a compressor placed in the holding device so that it can be moved using the buoyancy of the air. It is a float, and 7 is a connecting pipe that connects it.

Next, a schematic diagram of a measurement link is shown in FIG. 4, and the measurement principle will be explained.

In the figure, the link oa indicates an arbitrary n-th link, and the coordinates of the 0 point are known from the initial conditions. Furthermore, the distance l between links is constant.

Model links and show them as line segments. Move the link oa, which is initially on the y-axis, on the yx plane, and change the link ob
and then move in a plane perpendicular to the yx plane and click
oc, and consider the change in coordinates from point a to point c when the angle of displacement of each link is α and β.

Since the length of the link is l, If the coordinates of point 0 are (0, 0, 0), then Coordinates of point a (0,0,l) Coordinates of point c z=l sinβ x=l cosβ sinα y=l cosβ cosα becomes.

Therefore, by measuring the deformation angles α and β of the link, the coordinates of point c can be determined.

Description of the recording processing section The recording processing section uses a pressure sensor as a sensor, switches the signal to an analog multiplexer, converts it to a digital signal with an A/D converter,
Input/output interface device and data files, analysis, calculation,
The system consists of a personal computer that performs display and printing.

The content of the measurement process is (b) Original data file: Printing (b) Shape analysis by correction and calculation of original data (c) Two-dimensional vertical section and cross section display (d) Three-dimensional display (e) Data analysis, file etc.

A system conceptual diagram and system flow are shown in FIGS. 5 and 6.

Description of Holding Unit The holding mechanism for the measuring unit is a mechanism that holds the measurement unit from above the wave bank body as shown in FIG.

The holding device is a device adapted from a known backhoe type construction machine, and supports the tip of the inclinometer-type measuring section during measurement, and extends it over the surface of the irregularly shaped block.

The tip of the arm is equipped with an underwater television camera 8 to prevent collisions, and the operator performs measurement operations while watching the monitor television 9. Furthermore, it is provided with a winding device 11 for the inclinometer-type measuring band 10, and an air supply device 1 for the float 6.
2 and an inlet/drainage device 13.

c action I will explain it along with the effects.

C Effect of the invention Consisting of a measuring section, a recording processing section, and a holding section, the measuring section is a series of measuring bands with a number of links each having a universal joint at both ends, and is configured to be able to float and sink freely. As mentioned at the beginning, the structure is such that the holding section installed on the embankment is brought into contact with the wave-dissipating surface of the irregularly shaped block, and the signal from the tilt sensor of the measuring section is displayed and plotted by the recording processing section. The finished shape of a group of irregularly shaped blocks can be easily and reliably managed from above the water.
