[0003] Electricity generated at power plants is converted to low voltage at substations and supplied to homes through low-voltage power lines. Generally, these low-voltage power lines are installed on utility poles 5 to 6 meters above the ground to prevent contact with people or vehicles. This corresponds to the height of the second or third floor of a row house.

[0004] Accordingly, when moving household items to a unit located on the 2nd or 3rd floor, there was a problem in that the aforementioned low-voltage power lines interfered with the use of a ladder truck. To solve this, work was previously carried out to install protective conduits or temporarily remove the low-voltage power lines from the distribution control room, but there was a problem in that moving was delayed when the construction schedule was delayed.

[0005] Therefore, in the past, moving companies implemented temporary measures, such as securing space by tying ropes to the aforementioned low-voltage power lines and pulling them. However, this had the problem that safety accidents, such as electric shock, could occur.

[0006] A related prior art is Korean Patent Registration No. 10-2641637, titled "Indirect Live-Line Wire Lifting Device and Indirect Live-Line Work Method Using the Same." This invention involves lifting a wire from surrounding facilities to secure workspace during the process of performing live-line work in a power distribution system.

[0007] However, conventionally developed lifting devices had problems such as increased weight, maintenance costs, and significantly high manufacturing costs because the horizontal movement means of each support stick to accommodate cable spacing adjustment was considerably complex, required many parts, and necessitated a power supply. The problem to be solved

[0009] The problem that the present invention aims to solve is to provide a low-voltage power line lifting device that solves the problems of the aforementioned prior art. Specifically, it provides a low-voltage power line lifting device that can lift low-voltage power lines by simply installing it on the ground without the need for separate construction.

[0013] In addition, the mounting ring may be positioned on the upper side of the mounting portion and may be in the form of a ring with one side open.

[0014] And, the mounting portion may include a mounting portion body; and a protrusion formed protruding from the mounting portion body.

[0015] Additionally, the above-described ground low-voltage power line lifting device further includes a support member coupled to the lower end of the mounting member and supporting the mounting member; and the support member may include a coupling groove in which the protrusion is received.

[0016] In addition, the mounting body may include a first mounting body having a rectangular prism shape; and a second mounting body having a cylindrical shape disposed on the lower side of the first mounting body.

[0017] Additionally, the lifting member may include a bottom member supporting the ground; a pair of leg members hinged to the bottom member; a threaded rod penetrating the pair of leg members and having threads formed on its outer surface; and a handle coupled to one end in the longitudinal direction of the threaded rod.

[0024] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0026] FIG. 1 is a drawing showing a state in which a wire is mounted on a low-voltage wire lifting device according to one embodiment of the present invention, FIG. 2 is a drawing showing a mounting part of a low-voltage wire lifting device according to one embodiment of the present invention, FIG. 3 is a drawing showing a support part of a low-voltage wire lifting device according to one embodiment of the present invention, and FIG. 4 is a drawing showing a lifting part of a low-voltage wire lifting device according to one embodiment of the present invention.

[0028] As illustrated in FIGS. 1 to 4, a ground low-voltage wire lifting device (hereinafter referred to as the low-voltage wire lifting device (1)) according to an embodiment of the present invention includes a mounting part (10) that is formed to extend along one direction and includes a mounting hook (11) on which a wire is mounted, and a lifting part (20) that is positioned below the mounting part (10) and adjusts the height of the mounting part (10).

[0030] First, the mounting portion (10) may be in the shape of a column extending along one direction. It includes a mounting hook (11) on which a wire is mounted. A mounting hook (11) on which a low-voltage wire is mounted is positioned on the upper side of the mounting portion (10), and a protrusion (13) is formed on the lower side of the mounting portion (10). Additionally, a lifting portion (20) for adjusting the height of the mounting portion (10) is attached to the lower end of the mounting portion (10). The mounting portion (10) may be made of an insulating material.

[0032] The mounting ring (11) is positioned on the upper side of the mounting part (10) and may be in the shape of a ring with one side open. More specifically, the mounting ring (11) may be in the shape of a ring with the upper side open and the lower side concave. Accordingly, a low-voltage wire (2) located 5 to 6 meters above the ground can be received in the concave part of the mounting ring (11). Therefore, when the mounting part (10) is raised by the lifting part (20), the low-voltage wire (2) received in the concave part of the mounting ring (11) is also raised accordingly.

[0033] Additionally, a plurality of mounting hooks (11) may be formed. For example, a plurality of mounting hooks (11) may be formed along the longitudinal direction of the mounting portion (10). According to one embodiment of the present invention, four mounting hooks (11) may be formed along the longitudinal direction of the mounting portion (10). Accordingly, by accommodating one wire in each mounting hook (11), multiple low-voltage wires can be mounted and raised simultaneously.

[0035] Additionally, the mounting portion (10) may include a mounting portion body (12) and a protrusion (13). The mounting portion body (12) may refer to a column-shaped body portion that is not protruding from the mounting portion (10), and the protrusion (13) may refer to a portion protruding from the lower side of the mounting portion (10). When the mounting portion (10) is combined with the support portion (30), the protrusion (13) may be received inside the support portion (30). For example, a pair of protrusions (13) may be formed. One of the pair of protrusions (13) may be located in the opposite direction of the other protrusion (13).

[0037] Meanwhile, the mounting body (12) may include a first mounting body (12a) which is in the shape of a square column and a second mounting body (12b) which is in the shape of a cylinder and is coupled to the bottom of the first mounting body (12a). That is, the first mounting body (12a) corresponds to the upper side of the mounting part (10), and the second mounting body (12b) corresponds to the lower side of the mounting part (10). The first mounting body (12a) may be a part for mounting the low-voltage wire (2) by having the mounting hook (11) arranged thereon. Meanwhile, the second mounting body (12b) corresponds to the lower side of the mounting part (10) and is a part coupled to the support part (30), and the protrusion (13) may be formed thereon.

[0038] First, the first mounting body (12a) can be formed in the shape of a rectangular prism. The part to which the mounting hook (11) is attached is a flat surface, which is one of the four sides of the first mounting body (12a). Therefore, the operator can rotate the low-voltage wire lifting device (1) with respect to the longitudinal axis so that the corresponding flat surface is positioned parallel to the wire. As a result, the mounting hook (11) is oriented toward the low-voltage wire (2), allowing the low-voltage wire (2) to be mounted. The shape of the first mounting body (12a) can be used as a guide to easily mount the low-voltage wire (2) located at a height of 5 to 6 meters from the ground.

[0039] Additionally, the second mounting body (12b) may be cylindrical in shape. The lower side of the second mounting body (12b) may be accommodated inside the support member (30). The shape of the groove may be formed to correspond to the shape of the second mounting body (12b). For example, a cylindrical groove may be formed on the upper part of the support member (30).

[0040] Additionally, the second mounting body (12b) may further include a protrusion (13). The protrusion (13) may be formed on the lower side of the second mounting body (12b). More specifically, the protrusion (13) may be formed in a portion that is received inside the support portion (30) of the second mounting body (12b).

[0041] The support member (30) may further include a coupling groove (31). The coupling groove (31) may be formed by being recessed into the inner surface of a cylindrical groove. Additionally, the coupling groove (31) may be in the shape of a straight slit formed along the longitudinal direction of the support member (30) so that a protrusion (13) coupled to the upper part of the support member (30) can be inserted. The shape of the coupling groove (31) may be formed to correspond to the shape of the protrusion (13). Accordingly, the mounting member (10) and the support member (30) can be fixed while coupled.

[0043] Additionally, the low-voltage wire lifting device (1) may include a support member (30). The support member (30) is coupled to the lower end of the mounting member (10) and can support the mounting member (10). For example, the support member may be in the shape of a rectangular prism. The lower side of the second mounting member body (12b) may be accommodated inside the support member (30). Accordingly, the shape of the support member (30) may be a rectangular prism in which the diagonal length of the cross-section of the support member (30) is longer than the diameter of the cross-section of the second mounting member body (12b). A cylindrical groove may be formed at the top of the support member (30).

[0044] The support member (30) may include a coupling groove (31) in which the protrusion (13) is received. The coupling groove (31) may be formed by being recessed into the inner circumference of a cylindrical groove of the support member (30). The shape of the coupling groove (31) may be formed to correspond to the protrusion (13).

[0046] Additionally, the low-voltage wire lifting device (1) may further include a lifting section (20). The lifting section (20) is positioned below the mounting section and can adjust the height of the mounting section. The lifting section (20) may use a device capable of adjusting the height. Preferably, the lifting section (20) may be a jack.

[0047] More specifically, the above-mentioned lifting portion may be configured to include a bottom portion (21), a leg portion (22), a screw rod (23), and a handle (24).

[0048] First, the bottom part (21) can support the ground. The bottom part (21) can be hinge-connected to the leg part (22). The bottom part (21) can be formed of a heavy material so that the low-voltage wire lifting device (1) can maintain stability while installed on the ground.

[0049] The leg portion (22) may be hinge-connected to the upper surface of the bottom portion (21). The leg portion (22) may be rod-shaped. The leg portion (22) may be formed of the same material as the bottom portion. A pair of leg portions (22) may be formed. Each leg portion (22) may further include a hinge in the middle. Accordingly, the leg portion (22) may operate to be folded and unfolded. Additionally, the leg portion (22) may further include a bolt hole for receiving a screw rod (23).

[0050] A threaded rod (23) having threads formed on its outer surface can be received in the bolt hole of the leg portion (22). The threaded rod (23) can penetrate both of the pair of leg portions (22). That is, the pair of leg portions (22) can be connected by the threaded rod (23).

[0051] A handle (24) can be attached to one end of the screw rod (23) in the longitudinal direction. The handle (24) can be attached in a direction perpendicular to the longitudinal direction of the screw rod (23). The operator can rotate the screw rod (23) about the longitudinal axis through the handle (24). When the screw rod (23) rotates about the longitudinal axis, a pair of leg portions (22) attached to the screw rod may move closer to or further apart from each other.

[0052] For example, the operator can turn the handle clockwise. Accordingly, the screw rod (23) rotates about the longitudinal axis. As the screw rod (23) rotates, a pair of leg portions (22) that receive the screw rod can move closer to each other. Thus, the overall height of the lifting portion (20) can be increased.

[0053] On the other hand, the operator can turn the handle counterclockwise. Accordingly, the screw rod (23) rotates in the opposite direction to the rotation direction with respect to the longitudinal axis. As the screw rod (23) rotates in the opposite direction, a pair of leg portions (22) that accommodate the screw rod can move further apart from each other. Thus, the overall height of the lifting portion (20) can be reduced.

[0054] Accordingly, the operator can raise or lower the mounting part by rotating the handle while the low-voltage wire is mounted on the mounting part.

[0056] According to embodiments of the present invention having such a shape and structure, no separate construction or additional operation is required, allowing low-voltage power lines to be raised in a short period of time. Furthermore, according to the present invention, there is an effect of safely raising low-voltage power lines.

[0057] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the invention as claimed in the patent claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
