Abstract

PURPOSE:To elevate an elevation leveling rod automatically and to measure a horizontal plane to a reference plane by one-person operation by operating a transmitter while looking in a level, and controlling a motor under remote control. CONSTITUTION:A level measuring instrument main body 2 is fixed to the peak part of the support shaft 1 of a level measuring instrument and the elevation leveling rod 4 is arranged penetrating the machine frame 3 of the main body 2 so that it can be elevated. A driving part 5 drives and elevates the leveling rod 4 and a receiver device 6 receives a driving control signal from the transmitter 15 that an operator operates, so that the driving part 5 is controlled with the received signal. Further, the leveling rod 4 is arranged on a shaft 11 projected at the center part of a turntable 12 and coupled with the driving part 5 through a rack 9 and a gear 8. Then the rack 9 is driven by a small-sized motor which is not shown in a figure to elevate the leveling rod 4 under the operation command of the one operator, thereby measuring the horizontal plane to the reference plane.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a level measuring device used in construction, civil engineering, etc. Conventional technology Conventionally, leveling devices used in construction, civil engineering, etc. have consisted of a spirit level and a staff. It consists of a combination of To measure the level W with respect to a specific reference point using this device, look at the scale of the leveling rod held upright at the position to be measured through the telescope of the leveling instrument set at a predetermined position, and make sure that the specified scale is at the reference point of the leveling instrument. This is done by adjusting the height of the leveling rod so that it matches the line. Therefore, conventional leveling requires at least two people: an observer who looks through the telescope of the leveling instrument, and a leveller who holds and raises and lowers the leveling rod.
was.

Problems to be Solved by the Invention As mentioned above, the conventional level measurement required at least two people, and it was not possible for one person to measure the level in Dutch studies.

The present invention was created in view of the above circumstances, and includes:
The object of the present invention is to provide a level measuring device that allows even a person to measure the level of a container.

Means for Solving the Problems In order to solve the above-mentioned problems, the leveling device of the present invention includes a lifting staff that is movably supported on a platform, a motor that drives the lifting staff up and down, and a remote control system for driving the motor. A configuration characterized by comprising a remote control means was adopted.

By operating the transmitter while looking through the working level and controlling the motor from the remote side, the vertical leveling rod is automatically raised and lowered, and the water level relative to the reference surface can be measured. Therefore, even one person can measure the level.

Embodiments Hereinafter, embodiments of the level measuring device of the present invention will be described in detail based on the drawings.

In the embodiment shown in FIGS. 1 to 3, there is a single support leg, and the level measuring device main body 2 is fixed to the top of the support leg. The main body 2 includes a vertical leveling rod 4 that passes through the machine frame 3 of the main body 2 and moves up and down, and a drive section 5 that drives the vertical leveling rod 4 up and down.
and a receiver device 6 that receives the drive control signal from the transmitter 15 and controls the drive section.

As shown in FIG. 3, the vertical leveling rod 4 has a support hole 7 for the shaft 11 of the turntable 12 in the center, a rack 9 that engages with the gear 8 of the drive unit on the negative side, and a rack 9 on the other side. It is formed into a prismatic shape with appropriate scales 1o provided thereon. The turntable 12 is provided on the table surface to support a marker such as a pen protruding from the outer peripheral surface and to mark the level position on a wall surface etc. by rotating the level measuring device table. It is.

The drive device 5 includes a small motor (not shown) and a gear 8 that is rotationally driven by the motor and meshes with the rack 9.

In the figure, 13 is a batch IJ+, ]4 is a receiving antenna, 16 is a leveling instrument, and 17 is a transmitting antenna.

To measure the level with the level measuring device configured as described above, install the measuring device main body at the level measuring position, operate the transmitter 15 while holding the telescope of the leveling instrument, and drive the motor. Raise and lower the leveling rod 4 to align the turntable surface with the reference line. From this K, the top surface of the turntable 12 becomes the desired level position. Thereafter, the turntable 12 is manually rotated, and the level position is marked on the object to be measured using a marker held on the table.

FIG. 4 shows a pond embodiment of the level measuring device of the present invention.

In the device of this embodiment, the measuring device main body 2 is mounted on the top plate 21 of the tripod 20.
2 is fixed. Further, as in the previous embodiment, a turntable 25 is supported at the top of the elevator rod 24. In this embodiment, a shaft support 27 is fixed to the turntable 25 and supports a water pump shaft 26 so as to be slidable in the water direction. A pen 2 that can freely protrude is attached to the tip of the water rod 26.
While fixing the marker 29 having a
is fixed vertically. The configuration of the pond is substantially the same as in the previous embodiment.

To measure the level using the device of this embodiment, position the device opposite the surface of the object to be measured, adjust the protruding length of the water rod 26, and operate the transmitter in the same manner as in the previous embodiment. As a result, the elevator rod 24 is raised and lowered by remote control. The device of this embodiment is configured to align the desired scale of the straight scale with the reference line. After measuring the level position, the water mower shaft 26 is rotated and a mark is placed on the surface of the object to be measured using the pen 28.

In each of the above embodiments, the turntable is configured to be rotated manually, but an electric rotation mechanism may be provided and the turntable may be configured to be rotated by remote control in the same way as raising and lowering the leveling rod. At that time, if the marker is equipped with a pen protrusion mechanism and configured so that the pen protrusion can be controlled by remote control, it is possible to automatically attach a reference mark to the measurement target by remote control. .

Furthermore, in the above embodiment, the measurement device main body was supported by a support leg or a tripod, but the measurement device main body is provided with a retaining means that engages with the wall surface of the object to be measured, so that it can be directly supported on the wall surface of the object to be measured. It may be configured.

Effects The leveling device of the present invention is configured as described above, and the leveling rod can be raised and lowered automatically by a remote subsidiary, so that only the observer can measure the level, which saves the labor of conventional leveling. It is possible to aim for Further, since the leveling rod is automatically raised and lowered while being held vertically, the leveling rod does not become stiff as in the case of a conventional leveling rod, and accurate leveling can be performed. Further, by providing a marker on the turntable, it is possible to accurately mark the level position on the object to be measured.
