Description

Technology Field

[0001] The present invention relates to a geodetic surveying device, and more specifically, to a geodetic surveying device that can easily fix a leveling rod to the ground, thereby minimizing measurement errors by ensuring the leveling rod maintains its original position when changing direction, and reducing work fatigue by allowing the leveling rod operator to move the leveling rod to each point without effort, and enabling measurement work to be performed quickly. Background Technology

[0003] In general, geodetic surveying must be carried out first for various civil engineering or architectural designs. Geodetic surveying refers to all activities involved in measuring horizontal distances, elevation differences, and directions to determine the relative positions of measurement points, representing them in drawings or numerical values, and conducting on-site surveying.

[0004] Among these geodetic surveys, leveling is a survey that determines the height difference between two points using a leveling rod and a leveler, and it requires such detailed surveying that the accuracy is specified to be within 5 mm × S / 2 (where S is the one-way distance, and the unit is km) in the case of Class 2 leveling.

[0005] The method of measuring levels using a leveling rod and a leveler is explained as follows.

[0006] In the first step, the leveler sets the leveling rod at a ground reference point with a known altitude, and the mechanic reads the scale of the leveling rod with a leveler at a first observation point located at a certain distance.

[0007] In the second step, the leveling rod operator moves to the first point and sets up the leveling rod, and the machine operator reads the scale at the first point. Here, the altitude of the first point is calculated from the difference between the ground reference point and the scale read at the first point, and the altitude of the ground reference point.

[0008] In the third step, the machine operator moves to the second observation point behind the first point, and when the leveler redirects the level at its original position (the first point) so that it faces the leveler, the machine operator reads the level of the level at the first point from the second observation point using the leveler.

[0009] In the fourth step, the leveler moves to the second point and sets up the leveling rod, and the mechanic reads the scale at the second point from the second observation point. Here, the altitude of the second point is calculated from the difference between the scale readings from the first point and the second point.

[0010] In this manner, continuously move the leveling rod and the leveler, switch the direction of the leveling rod at each point and the leveler at each observation point, read the scales, and determine the altitude of each point to the target point.

[0011] However, conventional leveling rods are combined to allow length adjustment using a sliding mechanism, and in the third step, when the leveler changes the direction of the leveling rod, the leveler must lift the leveling rod from the ground to change its direction and then lower it back to its original position. However, there are frequent instances where the leveler fails to accurately lower the leveling rod back to its original position, resulting in measurement errors.

[0012] In addition, when surveying a large area, the leveling rod operator must carry a heavy leveling rod and move to many points such as ground control points, first point, second point, third point, etc., and set up the leveling rod at the correct point each time, which causes severe work fatigue for the leveling rod operator and problems such as delays in work.

[0013] Therefore, there is a need to develop a technology that minimizes measurement errors by ensuring the leveling rod maintains its original position when changing direction, and also reduces work fatigue and enables the work to be carried out quickly by allowing the leveling rod operator to move the leveling rod to each point without effort.

[0014] The aforementioned technical configuration is provided as background technology to aid in understanding the present invention and does not refer to prior art widely known in the technical field to which the present invention belongs. The problem to be solved

[0016] The present invention aims to solve the above-mentioned problems by providing a geodetic surveying device that can easily fix a leveling rod to the ground, thereby minimizing measurement errors by ensuring the leveling rod maintains its original position when changing direction, reducing work fatigue by allowing the leveling rod operator to move the leveling rod to each point without effort, and enabling measurement work to be performed quickly. means of solving the problem

[0018] According to one aspect of the present invention, the invention comprises: a support body disposed on the ground; a support post height-adjustably connected to the support body and equipped with a scale indicator; a lighting unit rotatably installed on the support post; a position indicator installed on the lighting unit and rotating together with the lighting unit, which repeatedly flashes and irradiates light of different colors; a lifting support unit connected to the support body and supporting the support body so as to be raised and lowered; a handle unit connected to the support body; and a battery installed on the support body, wherein the support body comprises: a support base disposed parallel to the ground; a support block provided on the upper surface of the support base and rotatably supporting the support post; and a plurality of wheel members installed on the lower surface of the support base, wherein the support post comprises: a first post rotatably installed on the support block and having the scale indicator formed thereon; and a second post connected vertically and rotatably to the first post and having the scale indicator formed thereon. and includes a third post that is vertically and rotatablely connected to the second post, has a scale indicator formed thereon, and has a lighting unit installed thereon; the lighting unit includes a lighting connection block installed on the third post and having an angle indicator formed on its outer surface; a lighting connection post rotatably connected to the lighting connection block; a lighting head connected to the lighting connection post; a lighting member installed on the lighting head; and a rotation fixing part that penetrates the lighting connection block and contacts the lighting connection post, and limits the rotation of the lighting connection post; the position indicator includes a connecting plate installed on the outer surface of the lighting head and rotating together with the lighting head; a position block installed on the connecting plate; and a plurality of position lights installed on the position block that repeatedly flash and irradiate light of different colors; and the lifting support includes a connecting block installed on the support base; a lifting drive unit installed on the connecting block; and a lifting unit connected to the lifting drive unit and moving up and down in the direction of the ground.A geodetic surveying device capable of easily fixing a leveling rod to the ground may be provided, characterized in that it includes a support flange installed at the end of the lifting portion and contacting the ground, and the handle portion comprises: a first connecting bar coupled to the support base; a second connecting bar connected to the first connecting bar so as to be vertical and rotatable; a third connecting bar connected to the second connecting bar so as to be vertical and rotatable and formed at an angle to the second connecting bar; a bending bar connected to the end of the third connecting bar so as to be bent; and a display installed on the third connecting bar.

[0019] The angle display unit is positioned in a direction intersecting the extension direction of the scale display unit, and the lighting unit and the position display unit can indicate the position of the scale display unit by rotating within the angle range indicated on the angle display unit and irradiating light toward the scale display unit. Effects of the invention

[0021] According to the present invention, since the measuring rod can be moved to each point using a trolley, the work fatigue of the measuring rod operator can be reduced, and the measuring rod can maintain its original position when changing direction, thereby minimizing measurement errors and allowing the measurement work to be performed quickly.

[0022] Since the lighting unit illuminates the scale indicator, the scale can be accurately read with the level even at night or in dark environments, and since the position indicator repeatedly flashes different colored lights, the operator can easily identify the position of the level even from a distance.

[0023] An angle indicator is formed on the outer surface of the lighting connection block, and since the lighting unit and the position indicator rotate within the angle range indicated on the angle indicator, the illumination angle of the lighting unit can be precisely adjusted to accurately indicate the position of the scale indicator, and the rotation of the lighting connection post can be restricted by the rotation fixing part to stably maintain the set illumination angle.

[0026] In order to fully understand the present invention, the operational advantages of the present invention, and the objectives achieved by the implementation of the present invention, reference must be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described therein.

[0027] The present invention will be described in detail below by explaining preferred embodiments of the invention with reference to the attached drawings. Identical reference numerals in each drawing indicate identical components.

[0028] FIG. 1 is a perspective view illustrating a geodetic surveying device that can easily fix a leveling rod to the ground according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating a state in which a lifting support member is operated in a geodetic surveying device according to an embodiment of the present invention, FIG. 3 is a perspective view illustrating a state in which a support post is lifted and rotated in a geodetic surveying device according to an embodiment of the present invention, and FIG. 4 is a perspective view illustrating a state in which a lighting member is rotated in a geodetic surveying device according to an embodiment of the present invention.

[0029] A geodetic surveying device (1) according to one embodiment of the present invention includes a support body (100), a support post (200), a lighting unit (300), a position display unit (400), a lifting support unit (500), a handle unit (600), and a battery (700).

[0030] The above support body (100) is placed on the ground and is a foundation structure on which each component of the geodetic surveying device (1) is installed. A support post (200), a lifting support part (500), a handle part (600), and a battery (700) are installed on the support body (100), and the support body (100) can move along the ground while stably supporting these components. The support body (100) includes a support base (110), a support block (120), and a wheel member (130).

[0031] The support base (110) is positioned parallel to the ground. The support base (110) may be formed in the shape of a square plate, but is not limited thereto and may be modified into various shapes such as a circular plate.

[0032] The above support base (110) may be made of a metal material having rigidity to stably support the load of the support post (200), the lifting support part (500), the handle part (600), and the battery (700).

[0033] A support block (120) is provided in the center of the upper surface of the support base (110), and a plurality of wheel members (130) are installed on the lower surface of the support base (110). Since the support base (110) is positioned parallel to the ground, the support post (200) supported by the support base (110) can be erected vertically with respect to the ground, and accordingly, altitude measurement through the scale of the scale display part (240) can be accurately performed.

[0034] The support block (120) is provided on the upper surface of the support base (110) and rotatably supports the support post (200). An insertion hole may be formed inside the support block (120) into which the lower end of the support post (200), i.e., the lower end of the first post (210), is inserted, and a bearing member may be interposed between the support block (120) and the first post (210) to allow the first post (210) to rotate smoothly.

[0035] Since the support post (200) is rotatably installed on the support block (120), when changing the direction of the gauge, there is no need to lift the gauge from the ground to change direction and then lower it again as in the conventional method; instead, the support post (200) can be rotated in place while the support body (100) is fixed to the ground. Since the gauge can maintain its original position, it is possible to prevent measurement errors caused by the change in the position of the gauge during the direction change process.

[0036] A plurality of the above wheel members (130) are installed on the bottom surface of the support base (110). The wheel members (130) can be installed at the corners of the bottom surface of the support base (110) and can be exemplified as caster types so that the direction can be freely changed.

[0037] Since the support body (100) can be moved along the ground by means of the wheel member (130), the surveyor can easily move to each survey point, such as a ground reference point, a first point, and a second point, by simply pushing or pulling the surveying device (1) without having to carry a heavy surveyor on their shoulder or hold it in their hand.

[0038] The support post (200) is connected to the support body (100) in a height-adjustable manner and is equipped with a scale display part (240). The support post (200) is a part that performs the inherent function of a leveling rod, providing a scale to be read by a leveler during surveying, and is rotatably supported by the support block (120) so that it can change direction in place. The support post (200) includes a first post (210), a second post (220), and a third post (230).

[0039] The first post (210) is rotatably installed on the support block (120), and a scale mark (240) is formed on its outer surface. The first post (210) may be formed in a hollow cylindrical shape, and a second post (220) may be movably accommodated inside.

[0040] The lower part of the first post (210) is inserted into the support block (120) and supported so as to be rotatable, so that the entire support post (200) can be rotated together by the rotation of the first post (210).

[0041] The second post (220) is connected to the first post (210) so as to be vertical and rotatable, and a scale indicator (240) is formed on its outer surface. The second post (220) is formed in the shape of a hollow cylinder with a smaller diameter than the first post (210) and can be inserted into the interior of the first post (210) so as to be slidably moved, and the overall height of the support post (200) varies depending on the degree to which it is withdrawn from the first post (210).

[0042] The third post (230) is connected to the second post (220) so as to be vertical and rotatable, has a scale indicator (240) formed on its outer surface, and has a lighting unit (300) installed on its upper end. The third post (230) is formed with a smaller diameter than the second post (220) and can be inserted into the interior of the second post (220) so as to be slidably movable.

[0043] In this way, since the first post (210), second post (220), and third post (230) are connected in a multi-stage retractable manner, the total height of the support post (200) can be freely adjusted according to the elevation difference of the surveyed terrain or survey conditions, and the height of the support post (200) can be minimized during storage and movement to improve handling.

[0044] Meanwhile, the connecting portion between the first post (210) and the second post (220) and the connecting portion between the second post (220) and the third post (230) may be provided with a fixing means, such as a clamp, for fixing the adjusted height.

[0045] The above scale indicator (240) is formed on the outer surface of the first post (210), the second post (220), and the third post (230), respectively, and is arranged to extend along the length direction of the support post (200).

[0046] The scale display section (240) may include scales and numerical values ​​displayed at regular intervals, and the operator can measure the altitude of each point by reading the scale of the scale display section (240) through a leveler at the observation point. The scale display section (240) may be formed in a color that contrasts with the outer surface of the support post (200) so that visibility from a distance can be ensured.

[0047] The lighting unit (300) is rotatably installed on the support post (200) and emits light toward the scale indicator (240) to enable reading of the scale even at night or in a dark environment. The lighting unit (300) includes a lighting connection block (310), a lighting connection post (320), a lighting head (330), a lighting member (340), and a rotational fixing part (350).

[0048] The lighting connection block (310) is installed on the third post (230), and an angle indicator (311) is formed on the outer surface. The lighting connection block (310) can be coupled to the upper part of the third post (230), and a hollow portion can be formed inside into which a lighting connection post (320) is rotatably inserted.

[0049] The angle indicator (311) is formed on the outer surface of the lighting connection block (310) and is positioned in a direction that intersects with the extension direction of the scale indicator (240). That is, while the scale indicator (240) extends along the length direction (up and down direction) of the support post (200), the angle indicator (311) is positioned along the circumference direction of the lighting connection block (310).

[0050] Angle scales at regular intervals may be displayed on the angle display unit (311), and the operator can precisely adjust the rotation angle of the lighting unit (300) by quantitatively checking the angle displayed on the angle display unit (311).

[0051] The lighting connection post (320) is rotatably connected to the lighting connection block (310). The lighting connection post (320) can be rotated relative to the lighting connection block (310) while inserted into the hollow portion of the lighting connection block (310), and the lighting head (330), lighting member (340), and position indicator (400) are rotated together by the rotation of the lighting connection post (320).

[0052] The lighting head (330) is connected to the upper part of the lighting connection post (320). The lighting head (330) may have a space formed inside for accommodating a lighting member (340), and an opening formed on one side for irradiating light from the lighting member (340).

[0053] An opening rim portion (331) is formed protrudingly on the outer surface of the lighting head (330) to surround the perimeter of the lighting member (340). The opening rim portion (331) protects the lighting member (340) from external impact and allows the light from the lighting member (340) to be irradiated more clearly.

[0054] The lighting element (340) is installed on the lighting head (330) and emits light toward the scale indicator (240). The lighting element (340) may be exemplified by an LED module with low power consumption and a long lifespan, but is not limited thereto.

[0055] Since the above-mentioned lighting element (340) irradiates light toward the scale display part (240), the operator can accurately read the scale of the scale display part (240) through the leveler even during night surveying or surveying work in dark environments such as inside a tunnel or underground structure, and accordingly, the time and place where surveying work is possible can be expanded and work efficiency can be improved.

[0056] The rotation fixing part (350) penetrates the lighting connection block (310) and contacts the lighting connection post (320), thereby restricting the rotation of the lighting connection post (320). The rotation fixing part (350) may be exemplified by a bolt member that is screw-coupled to the lighting connection block (310), and may be provided with a handle or knob at the end to facilitate gripping.

[0057] When the operator rotates the rotation fixing part (350) in one direction to tighten it, the end of the rotation fixing part (350) comes into pressurized contact with the outer surface of the lighting connection post (320), thereby restricting the rotation of the lighting connection post (320). When the operator rotates the rotation fixing part (350) in the other direction to loosen it, the pressure on the lighting connection post (320) is released, and the lighting connection post (320) becomes rotatable again. Accordingly, the illumination angle of the lighting part (300), which is set based on the angle display part (311), can be stably maintained without being arbitrarily changed during the surveying work.

[0058] The above-mentioned position indicator (400) is installed in the lighting unit (300) and rotates together with the lighting unit (300), and repeatedly flashes and illuminates light of different colors. The position indicator (400) is configured to allow a machine operator located at a distance to quickly identify the location of the geodetic surveying device (1), and includes a connecting plate (410), a position block (420), and a position light (430).

[0059] The above connecting plate (410) is installed on the outer surface of the lighting head (330) and rotates together with the lighting head (330). The connecting plate (410) may be formed to extend laterally from the outer surface of the lighting head (330) and serves as a medium for connecting the position block (420) to the lighting head (330).

[0060] The above position block (420) is installed on the connecting plate (410) and forms a body on which a plurality of position lights (430) are installed.

[0061] The above position lights (430) are installed in multiple numbers on the position block (420) and repeatedly flash and irradiate light of different colors. The position lights (430) can be exemplified by multiple LED modules that irradiate light of different colors, for example, by flashing red light and green light alternately.

[0062] Since the above-mentioned position lighting (430) repeatedly flashes and emits light of different colors, a machine operator located at a distant observation point can immediately identify the location where the geodetic surveying device (1) is set up, not only during the day but also at night, and accordingly, the machine operator can quickly align the direction of the level, thereby shortening the surveying work time.

[0063] In addition, since the flashing light has higher visibility than the continuously lit light, the location of the geodetic surveying device (1) can be clearly distinguished even in an environment where there are similar structures nearby.

[0064] Since the position indicator (400) is installed on the lighting head (330) via the connecting plate (410), it rotates together with the lighting unit (300) when the lighting connecting post (320) rotates. That is, regardless of whether the position indicator (400) rotates or the lighting head (330) rotates, the position indicator (400) and the lighting unit (300) rotate simultaneously while organically connected.

[0065] Accordingly, the lighting unit (300) and the position display unit (400) rotate as a single unit while sharing the angle range displayed on one angle display unit (311), and irradiate light toward the scale display unit (240) to indicate the position of the scale display unit (240).

[0066] Since the illumination direction of the lighting unit (300) and the display direction of the position display unit (400) can be aligned simultaneously with the direction of the observation point where the machine number is located, scale reading and position identification can be performed with a single rotation operation without separate operation.

[0067] The above lifting support member (500) is connected to the support body (100) and supports the support body (100) so that it can be lifted. The lifting support member (500) is configured to fix the support body (100) to the ground during surveying work and to release the fixation of the support body (100) during movement, and includes a connecting block (510), a lifting drive member (520), a lifting member (530), and a support flange (540).

[0068] The above connecting block (510) is installed on the support base (110). Multiple connecting blocks (510) may be provided, each installed at a corner of the support base (110), and a mounting portion is provided on which a lifting drive unit (520) is mounted.

[0069] The above lifting drive unit (520) is installed on the connecting block (510) and provides a driving force to move the lifting unit (530) up and down. The lifting drive unit (520) may be exemplified as an electric actuator that operates by receiving power from the battery (700), but is not limited thereto and may be modified to a screw jack method that raises the lifting unit (530) by manual operation.

[0070] The lifting unit (530) is connected to the lifting drive unit (520) and is raised in the direction of the ground. The lifting unit (530) is lowered by the operation of the lifting drive unit (520) to bring the support flange (540) into close contact with the ground, or is raised to separate the support flange (540) from the ground.

[0071] The support flange (540) is installed at the end of the lifting section (530) and comes into contact with the ground. The support flange (540) is formed in a plate shape that extends from the end of the lifting section (530) to secure a contact area with the ground, and accordingly, the support body (100) can be stably supported without sinking even on soft ground.

[0072] During surveying operations, the lifting unit (530) is lowered to bring the support flange (540) into contact with the ground, thereby distributing the load applied to the wheel member (130) to the support flange (540) and firmly fixing the support body (100) to the ground. This prevents the support body (100) from moving due to wind or external forces during surveying, thereby ensuring measurement precision.

[0073] Conversely, when moving, the lifting member (530) is raised to separate the support flange (540) from the ground, thereby allowing for rolling movement through the wheel member (130).

[0074] In this way, since the fixed state and the moving state are rapidly switched by a simple lifting operation of the lifting support member (500), work efficiency can be greatly improved due to the nature of level surveying work, which involves moving sequentially to multiple points for surveying.

[0075] The handle portion (600) is connected to the support body (100) and is a part that is grasped by the surveyor when moving the geodetic surveying device (1). The handle portion (600) includes a first connecting bar (610), a second connecting bar (620), a third connecting bar (630), a bending bar (640), and a display (650).

[0076] The first connecting bar (610) is coupled to the support base (110). The first connecting bar (610) can be installed to extend upward from the upper surface of the support base (110) and serves to support the entire handle portion (600) on the support base (110).

[0077] The second connecting bar (620) is connected to the first connecting bar (610) so as to be able to move up and down and rotate. The second connecting bar (620) can be connected to the first connecting bar (610) so as to be able to slide and rotate relative to it while inserted into the first connecting bar (610).

[0078] The third connecting bar (630) is connected to the second connecting bar (620) so as to be vertical and rotatable, and is formed at an angle to the second connecting bar (620). Since the third connecting bar (630) is formed at an angle to the second connecting bar (620), when the surveyor grips the bending bar (640), the position of the hand is separated laterally from the support body (100), thereby preventing interference between the surveyor's foot and the support body (100) during movement, and allowing the surveying device (1) to be moved in a natural walking posture.

[0079] The above-mentioned bending bar (640) is connected to the end of the third connecting bar (630) by being bent. The bending bar (640) is the part that the surveyor substantially holds, and may be provided with an anti-slip grip on its outer surface to improve the gripping sensation. The surveyor can move the geodetic surveying device (1) to each survey point by pushing or pulling it while holding the bending bar (640).

[0080] In this way, since the second connecting bar (620) is connected to the first connecting bar (610) and the third connecting bar (630) is connected to the second connecting bar (620) so as to be vertically and rotatable, the height and angle of the handle part (600) can be adjusted in multiple stages to match the height, working posture, and direction of movement of the figure.

[0081] Accordingly, workers of various body types can move the device in a comfortable position, which further reduces work fatigue, and when storing, the volume can be minimized by lowering and rotating the handle part (600).

[0082] The above display (650) is installed on the third connecting bar (630). Since the display (650) is positioned within the line of sight of the leveler while holding the bending bar (640), the leveler can easily check the status of the device while moving or working.

[0083] The display (650) may display the lighting status of the lighting member (340) and the position lighting (430), the operating status of the lifting support member (500), the remaining amount of the battery (700), etc., and the display (650) may be equipped with a touch panel capable of touch operation and may also serve as an operating unit that controls the operation of the lighting member (340), the position lighting (430), and the lifting drive unit (520).

[0084] The battery (700) is installed on the support body (100) and supplies power to the electrical configuration of the geodetic surveying device (1). The battery (700) may be installed on the upper surface of the support base (110) and supplies power to the lighting member (340), position lighting (430), lifting drive unit (520), and display (650).

[0085] The above battery (700) can be exemplified as a rechargeable and reusable secondary battery, and thus can be used for a long time even in outdoor surveying sites where power supply is difficult. Since the battery (700) is installed on the support base (110), the center of gravity of the device is located at the bottom, so the device can be prevented from tipping over even when the support post (200) is extended high.
