Description

A geodetic surveying system that can precisely measure the level of the ground surface {GEODETIC SURVEY SYSTEM FOR PRECISELY MEASURING LEVEL OF GROUND}

The present invention relates to a geodetic surveying system, and more specifically, to a geodetic surveying system that can precisely perform level surveying of the earth's surface.

In general, for various civil engineering or architectural designs, geodetic surveying must be performed first. Geodetic surveying refers to various activities such as measuring horizontal distance, elevation difference and direction, determining the location of each measurement point, displaying this in drawings or figures, and staking out on site.

Among these geodetic surveys, level surveying is a survey that determines the height difference between two points using measuring devices such as a marker, level, and total station. The accuracy is 5mm * S/2 in the case of level 2 surveying (here, S is the one-way distance (unit is km), so a detailed survey is required.

Figure 1 is a diagram illustrating a method of measuring level using a conventional marker and measuring equipment.

In the first step, the marker (1) sets the marker (1) at the ground reference point (a0) whose altitude is known, and the mechanical operator uses a level, etc. at the first observation point (b1) a certain distance away. Read the scale on the scale (1) with the measuring device (2).

In the second step, the marker moves to the first point (a1) and sets up the marker (1), and the mechanical operator changes the direction of the measuring instrument (2) at the observation point (b1) and measures the first point through the measuring instrument (2). Read the scale of the point. Here, the altitude of the first point is obtained from the difference between the scales read at the ground reference point (a0) and the first point (a1) and the altitude of the ground reference point.

In the third step, the machine operator moves to the second observation point (b2) behind the first point (a1), and the marker (1) changes direction in place (first point) so that the marker (1) performs the survey. When looking at the device (2), the operator reads the scale of the first point (a1) from the second observation point (b2) with the measuring device.

In the fourth step, the marker moves to the second point (a2) and sets up the marker (1), and the machine operator reads the marker scale at the second point (a2) from the second observation point (b2). Here, the altitude of the second point is obtained from the difference in scales between the first point (a1) and the second point (a2) read from the second observation point (b2).

In this way, while continuously moving the target scale (1) and the measuring device (2), the target marker at each point and the direction of the measuring device at each observation point are changed to read the scale to obtain the altitude of each point up to the target point.

At this time, in order to perform accurate geodetic survey work, the surveying equipment must be able to maintain a stable horizontal position and not shake even when external shock or vibration is applied.

For this purpose, conventionally, workers check the curvature of the ground where the geodetic survey device will be placed and manually adjust the length of the tripod supporting the geodetic survey device, and for more detailed leveling, horizontal bubble alignment means are added. It is being utilized.

The bubble aligning means is widely used as a standard for leveling devices by applying the principle that bubbles always face upward, and is a technology widely used in devices that require leveling.

However, the leveling work of the geodetic survey device is not only very cumbersome in that it has to be performed repeatedly each time the position of the geodetic survey device is adjusted, but also because all work is done manually, there are limits to accurate leveling, so the geodetic survey results are limited. There is a problem that the error rate is also not small.

In addition, the conventional geodetic surveying device has a problem in that when it receives surrounding vibration or shock during the geodetic surveying process, the measuring device shakes while reading the scale, making it impossible to read the scale accurately, thereby causing measurement errors. .

The lifting control cylinder 431 is coupled to the lower surface of the second horizontal base 420 and can be lifted up and down. When the lift control cylinder 431 operates and the length of the lift control cylinder 431 increases, the second horizontal base 420 moves away from the semicircular housing 432 and the second horizontal base 420 rises. When the lift control cylinder 431 operates in the opposite direction and the length of the lift control cylinder 431 decreases, the second horizontal base 420 approaches the semicircular housing 432 and the second horizontal base 420 is lowered.

The semicircular housing 432 is coupled to the lower part of the lifting control cylinder 431 and forms a semicircular space therein. The rotation fixture 433 is fixedly coupled to the upper surface of the first horizontal base 410, and the spherical rotation ball 434 is coupled to the upper part of the rotation fixture 433 and the upper side is accommodated inside the semicircular housing 432. do.

Since the semicircular housing 432 is rotatably coupled to the upper part of the rotating ball 434, the second horizontal base 420 can be tilted left and right to be level.

The rotation support portion 440 is coupled to the outside of the semicircular housing 432 and can move left and right, and supports the outer surface of the rotation ball 434.

As shown, the rotation support portion 440 includes an 'L' shaped support extension portion 441 coupled to the outside of the semicircular housing 432, and a rotation support cylinder horizontally coupled to the bottom of the support extension portion 441. 442), a rotation support case 443 that is coupled to one end of the rotation support cylinder 442 and has a space formed therein, and is accommodated inside the rotation support case 443 and can rotate left and right according to the operation of the rotation support cylinder. Includes a support rod (445).

At this time, a rotation contact portion 444 that is always in contact with the spherical rotation ball 434 is further coupled to the end of the rotation support case 443, and an end of the rotation support rod 445 is used to operate the rotation support cylinder 442. Accordingly, the rotation stop portion 446 that is exposed to the outside of the rotation support case 443 and contacts the spherical rotation support ball is further coupled.

The end of the rotation contact portion 444 is formed in a convex shape so as to contact and support the rotation ball 434 depending on the state of the spherical rotation ball 434, and the end of the rotation stop portion 446 supports the rotation ball 434. It is formed in a concave shape with the same curvature as the rotating ball 434 to enable strong pressure.

Since the soft rotating contact portion 444 is normally in contact with the spherical rotating ball 434, the semicircular housing 432 does not move rapidly even on an inclined surface and the second horizontal base 420 also moves slowly. Accordingly, it is possible to prevent the video image from shaking rapidly.

When the second horizontal base 420 is horizontal, the rotation support rod 445 operates to expose the rotation support rod 445 from the rotation support case 443, and the rotation stopper 446 is a spherical rotation ball ( The outside of 434) is strongly pressed to prevent the second horizontal base 420 from moving any further.

The second vibration case 452 is inserted into the first vibration case 451 and can move up and down.

The vibration rod 453 is formed in the form of a vertically long bar and is disposed inside the first vibration case 451 and the second vibration case 452. The width of the vibration rod 453 is the same as the internal width of the second vibration case 452, and since the vibration rod 453 is disposed inside the first vibration case 451 and the second vibration case 452, the second vibration rod 453 The vibration case 452 can be firmly coupled to the first vibration case 451 without being separated. The vibrating rod 453 is made of a permanent magnet having magnetism.

The first vibrating magnet member 454 is coupled to the bottom surface of the first vibrating case 451 and has a polarity opposite to that of the vibrating rod 453. The second vibration magnet member 456 is coupled to the ceiling surface of the second vibration case 452 and has a polarity opposite to that of the vibration rod 453.

Since the first vibration magnet member 454 and the second vibration magnet member 456 have a polarity opposite to that of the vibration rod 453, the first vibration magnet member 454, the second vibration magnet member 456, and the vibration A certain space is formed between the rods 453, and external shocks or vibrations are not directly transmitted to the second horizontal base 420.

In addition, the space between the first vibration magnet member 454 and the vibration rod 453 is connected by a first vibration elastic member 455 having elastic force, and the space between the second vibration magnet member 456 and the vibration rod 453 is connected by an elastic force. Since it is connected to the second vibration elastic member 457, external shock can be further absorbed secondarily.

Furthermore, the first vibration horizontal member 458a extends horizontally on the outer surface of the first vibration case 451, and the second vibration horizontal member 458c extends horizontally on the outer surface of the rotation fixture 433. , Since the first vibration horizontal member 458a and the second vibration horizontal member 458c are connected by a horizontal elastic member 458b having elastic force, the vibration transmitted through the elevation control unit 430 is also connected to the vibration control unit 450. can be absorbed by In other words, the vibration control unit 450 can absorb external shock or vibration three times.

The pair of horizontal adjustment units 460 are coupled between the first horizontal base 410 and the second horizontal base 420 and are disposed outside each of the pair of vibration control units 450. By adjusting the length of the horizontal adjustment unit 460, the second horizontal base 420 can be made horizontal. In addition, the horizontal adjusting unit 460 can auxiliaryly raise and lower the second horizontal base 420 from the outside during overall elevation through the lifting adjusting unit 430.

Specifically, the horizontal adjusting unit 460 includes a horizontal adjusting cylinder 461 rotatably coupled to the lower surface of the second horizontal base 420, and a horizontal adjusting rod rotatably coupled to the horizontal adjusting cylinder 461 to be raised and lowered. (462) and a horizontal support member 463 that is coupled to the upper surface of the first horizontal base 410 and supports the side of the horizontal adjustment rod 462.
