Description

Technology Field

[0001] The present invention relates to a position surveying device, and more specifically, to an underground facility position surveying device that can improve the efficiency of measuring and recording the location of underground facilities and the accuracy of the measurement results, allows for convenient storage by enabling the separation of each component, and enables multi-angle adjustment so as to be adjusted to correspond to the diameter of each underground facility. Background Technology

[0003] Recently, water and sewage lines, various communication lines, and various infrastructure facilities for urban development (hereinafter referred to as 'underground facilities') are buried underground for storage and protection.

[0004] Since such underground facilities cannot be exposed to the outside once buried, their burial location and type cannot be determined from the surface.

[0005] However, in order to repair and manage underground facilities that have problems in case of emergency, the buried location of the underground facilities must be accurately identified, and the identified location must be recorded so that the management of the underground facilities subject to search can be carried out effectively.

[0006] Korean Registered Patent Publication No. 10-0973591 (August 2, 2010) discloses a ‘single-person surveying target for real-time location measurement of underground facilities.’ However, this conventional single-person surveying target for real-time location measurement of underground facilities had a problem in that, although it could be withdrawn from the main body, it was difficult to maintain the length of the adjusted rod because the main body could not be secured to the main body.

[0007] Prior art for solving these problems is disclosed in Korean Registered Patent Publication No. 10-1721248 (March 23, 2017). However, although this prior art can maintain the length of the adjusted rod by being connected to the main body, the stability of the connection is poor because it is connected to an underground facility using the magnetic force of the stator, and the ease of operation and convenience are poor because it only has a tilting function of the rod and lacks functions such as rotation. Therefore, an improvement measure is required.

[0008] The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. The problem to be solved

[0025] The above cross attachment part (100) is connected to an underground facility (10), such as a sewer pipe or a gas pipe, and includes a first attachment part (110) with one side attached to the underground facility (10), as shown in FIG. 6, and a second attachment part (120) that is hinge-connected to the first attachment part (110) and has one side attached to the underground facility (10).

[0026] As shown in FIG. 6, the first attachment part (110) includes a first cross support (111) in which the upper part is coupled to a rotating guide part (200) and the lower part is positioned close to an underground facility (10), a first movable block (112) coupled to the first cross support (111) so as to be movable, and a first magnetic member (113) provided on the first movable block (112) to magnetically attach the first movable block (112) to the underground facility (10).

[0027] In this embodiment, the first cross support (111) and the second cross support (121) of the second attachment part (120) are joined to intersect each other, and the parts where they meet are hinge-joined so that they can rotate, thereby allowing the distance between the first cross support (111) and the second cross support (121) to be adjusted to correspond to the diameter of the underground facility (10), as shown in FIG. 3.

[0028] In the present invention, the first cross support (111) and the second cross support (121) may be formed from an aluminum alloy comprising 0.7 to 1.6 wt% copper, 0.8 to 1.7 wt% tin, 1.6 to 2.7 wt% cobalt, 0.6 to 1.6 wt% molybdenum, 0.6 to 1.3 wt% iron, 2.2 to 2.9 wt% titanium, 0.1 to 0.4 wt% zirconium, 0.1 to 0.6 wt% barium, 1.1 to 1.4 wt% silicon, 1.9 to 2.3 wt% calcium, and the remainder being aluminum.

Additionally, the adjustment of the spacing between the first cross support (111) and the second cross support (121) and the movement of the first movable block (112) may be applied together, or each may be adjusted separately.

[0032] As shown in FIG. 1, the first magnetic member (113) is coupled to the first movable block (112) so that the first movable block (112) can be attached to the underground facility (10) by magnetic force. In this embodiment, the strength of the magnet of the first magnetic member (113) can be determined by taking into account the foreign matter generally attached to the underground facility (10), for example, the underground pipe, and the material of the underground pipe.

[0033] As shown in FIG. 6, the second attachment member (120) comprises a second cross support member (121) that is hinge-coupled to the first cross support member (111), with the lower portion spaced apart from the upper portion of the first cross support member (111) and the upper portion positioned close to the underground facility (10), a second movable block (122) that is movably coupled to the second cross support member (121), and a second magnetic member (123) provided on the second movable block (122) to magnetically attach the second movable block (122) to the underground facility (10).

[0034] The second movable block (122) is coupled to the second cross support (121) so as to be movable, that is, to be movable in the longitudinal direction of the second cross support (121), so as to be movable to correspond to the diameter of the underground facility (10). The second movable block (122) can be screw-coupled to the second cross support (121).

[0035] In this embodiment, the second movable block (122) may be moved to be adjusted to correspond to the diameter of the underground facility (10), and additionally, the adjustment of the gap between the first cross support (111) and the second cross support (121) and the movement of the second movable block (122) may be applied together or each may be adjusted separately.

[0036] As shown in FIG. 1, the second magnetic member (123) is coupled to the second movable block (122) to attach the second movable block (122) to the underground facility (10) by magnetic force, and the strength of the magnet of the second magnetic member (123) can be determined by considering the foreign matter generally attached to the underground facility (10), for example, the underground pipe, and the material of the underground pipe.

That is, when the ball fastening nut (250) is screw-coupled to the outer wall of the rotating support post (220), the rotating support post (220) is pressed in the direction of the rotating support ball (230) housed inside, so that the rotating support ball (230) can be fixed in position so as not to move.

[0043] The above-mentioned rotating support ball (230) can be positioned to be received inside the rotating support post (220), and can be separated from the rotating support post (220) when the ball fastening nut (250) is separated from the rotating support post (220).

[0044] In this embodiment, the ball body (240) may be provided integrally with the rotational support ball (230), and a ball fastening bar (241) may be provided on the upper part of the ball body (240).

[0045] The ball fastening nut (250) is screw-coupled to the outer wall of the rotational support post (220) and can press the rotational support post (220) in the direction of the rotational support ball (230).

[0046] The above rod portion (300) is coupled to the upper part of the rotary guide portion (200), as shown in FIG. 1, and can be a surveying target for known and common surveying equipment such as a total station.

[0047] In this embodiment, the rod portion (300) includes a rod support body (310) that is detachably coupled to a rotation guide portion (200) as shown in FIG. 1, a first rod (320) coupled to the rod support body (310), a second rod (330) that is length-adjustably coupled to the first rod (320), and a fixing means (340) that detachably couples the first rod (320) to the rod support body (310).

As a result, the rod support body (310) can be detachably screw-coupled to the rotation guide part (200) by the screw coupling of the rod coupling groove (311) and the ball coupling bar (241).

[0049] In this embodiment, the second rod (330) may be lengthened by frictional force on the first rod (320).

[0050] In the present invention, the first rod (320) and the second rod (330) may be formed of a titanium alloy in which, in weight percent based on the total alloy weight, 3.4 to 7.8 weight percent aluminum, 0.8 to 1.3 weight percent iron, 0.1 to 0.8 weight percent zinc, 0.1 to 0.7 weight percent chromium, 0.3 to 4.4 weight percent molybdenum, 2.4 to 6.8 weight percent tin, 4.5 to 9.5 weight percent niobium, 0.8 to 3.2 weight percent zirconium, 0.02 to 0.04 weight percent carbon, 0.01 to 0.05 weight percent nitrogen, and the remainder being titanium and impurities.

[0051] When the first rod (320) and the second rod (330) are formed from such a titanium alloy, they have wear resistance, fatigue strength, and hot workability that surpass those of conventional titanium alloys, and manufacturing costs are reduced. Furthermore, compared to conventional titanium alloys, their applications are expanded as components for equipment and parts that have sliding movement, and mechanical properties are improved due to their lightweight and high strength characteristics. Therefore, they have the characteristic of maximizing the support force of the tripod while extending the lifespan of the second rod even when frequently withdrawing it from the first rod.

[0052] In this embodiment, the fixing means (340) may be configured to include a fixing bolt (341) that fastens the rod support body (310) and the first rod (320) as shown in FIG. 5, and a fixing nut (342) that is coupled to the fixing bolt (341) to fix the first rod (320) to the rod support body (310).

[0053] As seen above, this embodiment can improve the accuracy of the measurement results along with the economic efficiency of the work of measuring and recording the location of the underground facility (10).
