Description

{STAFF FOR LEVELING ON THE SLOP}

The present invention relates to a surveying sculpture capable of precise level-level surveying of slopes, which enables precise leveling even on slopes.

For civil engineering design and architectural design, first of all, geodetic survey of the construction site should be done. Here, the term "geodetic survey" refers to all activities for measuring the position, such as the horizontal distance, the elevation difference and the direction, between the points, and displaying the position in figures or numerical values.

Among these geodetic surveying methods, level measurement is a surveying method in which a height difference between two points is obtained by using a marking and leveling machine. In the prior art, a leveling survey is performed by using a motor and a screw, Quot; elevator height adjusting device "

However, most conventional leveling techniques, including the above-described prior art, presuppose a technique of installing a crest on a slope. This is because the scales installed on the target for leveling should be arranged vertically straight from the ground and should not be tilted.

Therefore, in order to erect the conventional skewer without tilting, the installation point had to be a completely horizontal floor, or the floor had to be laid on the floor when the installation point was inclined.

However, since most of the floors that need to be laid are unpaved or sloped, it has been urgently required to develop floors that can be set up for precise leveling even on slopes.

1, the elevator 100 of the present embodiment is vertically installed not only on a general horizontal plane but also on inclined diverse angles as shown in FIG. 1, thereby enabling accurate measurement of the level of the ground G using a multi station M or the like .

To this end, the skirt 100 of the present embodiment includes a base 110 that rests on the ground G and performs an anchor function for establishing the skeleton 100, a stand 110 that is connected to the base 110, 130 and a linker 120 for pivotally connecting the base 110 and the stand 130 in a pivotal manner.

The base 110 of the present embodiment has a relatively large weight for concentrating the load of the skeleton 100 at the lower end so that the skeleton 100 can maintain a stable standing condition, Respectively. The base 110 is connected to the outer case 111 having a hollow shape and hollow and the upper end of the outer case 111 so that the inner surface is connected to the peripheral face plate 122 of the linker 120 And a spherical curved surface receiving member 113 for receiving a linker 120 having a spherical shape in which the upper and lower ends of the sphere are cut.

The linker 120 of the present embodiment includes a base plate 121 on which the stand 130 is seated and a peripheral face plate 122 having a curved shape along the periphery of the base plate 121, So that a certain space is formed between the bottom plate 121 of the linker 120 and the bottom of the curved surface bearing 113. The linker 120 has a container shape in which the base plate 121 is surrounded by the peripheral face plate 122 and the lower end of the stand 130 is fixed to the upper face of the base plate 121. The coupling structure between the linker 120 and the base 110 will be described in more detail below. Since the linker 120 has a shape in which the upper and lower ends of the sphere are cut as described above, the circumferential face plate 122 of the linker 120 has a central portion protruding and upper and lower ends relatively concave. Therefore, when the linker 120 is placed on the curved surface bearing 113 having the same curvature as that of the linker 120, the linker 120 only rotates without being vertically moved by the curved surface bearing 113.

In order to adjust the length of the stand 130, as shown in the figure, two or more rulers 131 and 132 are movably connected along the longitudinal direction do. In the present embodiment, the second scale 132 is a joint structure in which the second scale 132 is removably inserted into the first scale 131, but the present invention is not limited thereto and the number of scales may vary.

FIG. 4 is a sectional view showing the internal structure of the table chuck according to the present invention, FIG. 5 is a perspective view showing the reference body of the table chuck according to the present invention, FIG. 6 is a cross- FIG. 2 is an enlarged cross-sectional view showing an enlarged view of FIG.

The embodiment of the present invention further includes a main magnetic body 140 and a sub magnetic body 150 in addition to the base 110, the linker 120, and the stand 130.

The main magnetic body 140 is movably seated in the hollow of the curved surface bearing 113 of the base 110 and moves along the inclination of the base 110. The main magnetic body 140 moves in the direction of gravity along the inner surface of the curved surface bearing 113 so that the bottom surface of the curved surface bearing 113 Face ').

The main magnetic body 140 for this purpose has a relatively larger load than the combined load of the linker 120 and the stand 130. To this end, the main magnetic body 140 is moved in the direction of the movable surface contact with the curved surface bearing 113 A weight member 141 having a curved plate shape having a curvature equal to the curvature of the curved surface support 113 and a main magnet 142 disposed on the upper surface of the weight member 141 with N and S poles arranged up and down . The main magnetic body 140 of the present embodiment includes a plurality of protrusions 143 protruding from the bottom surface of the weight member 141 in order to reduce frictional force between the weight member 141 and the curved surface bearing 113 which are in close contact with each other .

As a result, the main magnetic body 140 is always disposed on the floor surface which is the lowest point of the curved surface bearing 113 while moving in accordance with the attitude change of the curved surface bearing 113 forming the spherical shape.

The linker 120 is movable in surface contact with the curved surface bearing 113 in a curved surface shape in which the circumferential surface plate 122 protrudes while the circumferential surface plate 122 of the linker 120 is curved in the same curvature The peripheral face plate 122 of the linker 120 and the curved face support 113 are always in surface contact with each other and remain in a close contact state.

The end cover 112 is formed at the upper end of the outer case 111 of the base 110 to have a curved inner surface. Since the end cover 112 covers the upper end of the circumferential face plate 122 of the linker 120, (120) is caught by the end cap (112) and remains seated in the curved surface receiving member (113) without being separated from the base (110). The linker 120 can smoothly move along the curved surface support 113 and the end lid 112 without interference because the end lid 112 has an extended shape conforming to the curved surface shape of the curved surface support 113. [ Do.

When the linker 120 is seated on the curved surface bearing 113 of the spherical shape, the bottom plate 121 of the linker 120 and the curved surface bearing 113 A space is formed between the bottom surfaces of the base plates. In this space, the main magnetic body 140 is located opposite to the linker 120, and the sub-magnetic body 150 is installed on the bottom plate 121 of the linker 120.

The sub magnetic body 150 constitutes a sub magnet 152 corresponding to the main magnet 142 of the main magnetic body 140 and an adapter 151 for fixing the sub magnetic body 152 to the linker 120.

The sub magnet 152 is disposed at the lower end with the same polarity as the polarity positioned at the upper end of the main magnet 142 so as to generate a repulsive force with the main magnet 142 while the N pole and the S pole are arranged vertically. At this time, the repulsive force is smaller than the load of the main magnetic body 140, and is larger than the load of the linker 120 and the stand 130, thereby allowing the stand 130 to move and support by the repulsive force. The linker 120 and the stand 130 which receive the repulsive force with the main magnetic body 140 move in the same direction as the main magnetic body 140, And maintains a vertical posture while moving in a repulsive force direction.

The space between the curved surface support 113 and the linker 120 is maintained at a relatively high atmospheric pressure and the gap between the curved surface support 113 and the linker 120 is blocked by the packer 123 in the space. As a result, the air having a relatively high air pressure in the space is cut off through the gap, and the packer 123 is pressed against the inner surface of the curved surface bearing 113 of the clearance portion by the air applying pressure at a high air pressure, ) Of the linker 120 so as to prevent the linker 120 from moving.

Of course, the above-described function of the packer 123 allows the linker 120, which is positioned by the repulsive force of the main magnetic body 140 and the sub magnetic body 150, to keep the position constant without shaking.

The packer 123 of the present embodiment has a cross-sectional shape of 'A' which is in close contact with the inner surface of the curved surface bearing 113 and the bottom plate 121 of the linker 120. One or both ends of the packer 123 are air Is preferably inclined so as to prevent a gap between the inner surface of the curved surface bearing 113 and the packer 123 or a gap between the bottom plate 121 of the linker 120 and the packer 123 from leaking.

7 is a cross-sectional view illustrating an operation of the table chuck according to the present invention.

When the base 110 is placed on the inclined paper surface G, the base 110 is inclined by the inclination of the paper surface G. In this case,

At this time, the curved surface bearing 113 of the base 110 is inclined with the outer case 111 of the base 110, and the main magnetic body 140, which is seated on the curved surface bearing 113, Which is the lowest point of the floor.

The linker 120 and the stand 130 are also separated from the main magnetic body 140 with the movement of the sub magnetic body 150. The main magnetic body 140 is disposed at a position spaced apart from the main magnetic body 140 as much as possible, (140). As a result, the main magnetic body 140, the sub magnetic body 150, the linker 120, and the stand 130 are vertically arranged in a line, and the stand 130 is always vertically arranged regardless of the inclination of the ground G. .

The repulsive force of the main magnetic body 140 and the sub magnetic body 150 can be more easily applied to the stand 130 when the user grasps the stand 130 and adjusts it to be close to the vertical posture so that the stand 130 is more easily positioned. And the stand 130 thus positioned can accurately measure the level of the ground by the multi-station M while maintaining the current posture.
