Description

Technical Field

[0001] This invention relates to the field of power system safety tools and equipment, and in particular to an auxiliary device for installing overhead grounding wires. Background Technology

[0002] Installing grounding wires is an important part of the maintenance of overhead power distribution lines.

[0003] Currently, workers use a grounding wire manipulator to install and remove grounding wires. Due to the difficulty of operation and lack of standardized procedures, there are often many problems when installing and removing grounding wires, mainly in the following aspects.

[0004] First, during the process of ground crew passing grounding wires to workers on poles (towers) via a rope, problems such as the grounding wires becoming scattered, bumping into pole (tower) equipment, and the grounding wire handle rolling off are easily caused.

[0005] Secondly, the limitations of the work methods and operating procedures lead to unreasonable physical exertion by the workers. The operating procedures for installing and removing grounding wires require that the body must not touch the grounding wire during the process, and a safe distance must be maintained between the body and the conductor. Due to these limitations, when installing or removing grounding wires at heights, workers need to lean outwards to keep the grounding wire at a distance from their body, holding the wire and extending it outwards and upwards. Because of the heavy weight of the grounding wire, the limited strength exerted by the worker at height, and the fact that the center of gravity of the grounding wire is located on the outside of the body, the workers bear a heavy load on their waist and hands during these operations, which can easily lead to injuries to the joints of the waist and hands.

[0006] Third, the difficulty of installing and removing grounding wires leads to improper operation. According to operating procedures, when installing a combined-phase grounding wire, all three phases must be simultaneously connected to the grounding wire pre-installation point closest to the operator. After the grounding wire is passed to the worker, the worker must readjust its position and connect all three phases to a single pre-installation point before proceeding with the phase-by-phase installation. During this process, the worker wears insulated gloves throughout, making it difficult to simultaneously insert the installation holes for all three phases into the pre-installation point. Furthermore, the gloves cause slippage when tightening or loosening the grounding wire, further complicating the operation. Summary of the Invention

[0007] This invention provides an overhead grounding wire installation auxiliary device, which solves the technical problem of how to provide assistance to improve the convenience of operation when installing and removing grounding wires through the grounding wire operating rod. This avoids problems such as the grounding wire scattering during transmission, excessive physical load on the operator due to unreasonable physical exertion, and improper installation of grounding wires when installing and removing grounding wires through the grounding wire operating rod.

[0008] This invention provides an overhead grounding wire installation auxiliary device, comprising a snap-fit ​​part, a connecting part, and a base part connected in sequence;

[0009] The latching part includes a latching body and three hooks for latching the grounding wire operating rod. The three hooks are spaced apart on one side of the latching body, and the center lines of each hook are located in the same plane and are parallel to each other.

[0010] The base includes a base body and three fittings for connecting the tail of the grounding wire operating rod. The three fittings are spaced apart on one side of the base body, and the center lines of each fitting are located in the same plane and are parallel to each other.

[0011] The center lines of the three hooks are collinear with the center lines of the three sockets, so that when the three-phase grounding wire is connected, the three grounding wire operating rods connected by the hooks and the sockets are located on the same plane.

[0012] According to one embodiment of the invention, the socket is provided with an insert portion for inserting a grounding wire operating rod and a bottom portion rotatable along the socket hole.

[0013] The bottom portion is provided with a socket groove for connecting to the tail of the grounding wire operating rod.

[0014] According to one possible method of the present invention, the inner sidewall of the socket groove is provided with a rubber protective material.

[0015] According to one embodiment of the invention, the bottom surface of the bottom portion is provided with a threaded hole that matches a hexagonal screw.

[0016] According to one embodiment of the present invention, the overhead grounding wire installation auxiliary device further includes an extension rod;

[0017] The extension rod is provided with a hexagonal screw that connects to the threaded hole.

[0018] According to one achievable method of the present invention, the connecting portion is detachably connected to the snap-fit ​​portion and / or the base portion.

[0019] According to one possible method of the present invention, the hook is detachably connected to the buckle body.

[0020] According to one possible embodiment of the present invention, the buckle body is provided with a snap-fit ​​groove, and the hook is provided with a snap-fit ​​protrusion that matches and connects with the snap-fit ​​groove.

[0021] According to one possible embodiment of the invention, the socket is detachably connected to the base body.

[0022] According to one embodiment of the present invention, the base body is composed of three detachably connected base body units, and each base body unit is provided with a socket on one side.

[0023] When using the overhead grounding wire installation auxiliary device, the three grounding wire operating rods of the three-phase grounding wire operating rod can be snapped together by the buckle part, and the tail of the three grounding wire operating rods can be sleeved onto the socket of the base part, so that the three grounding wire operating rods are fixed into a whole and kept on the same plane. When installing or removing the grounding wire, the base part can be placed on the legs as a fulcrum, and the connecting part can be held with both hands to hang the grounding wire of the three-phase grounding wire operating rod onto the conductor.

[0024] As can be seen from the above technical solutions, the present invention has the following advantages:

[0025] The auxiliary device of the present invention includes a latching part, a connecting part, and a base part connected in sequence. The latching part includes a latching body and three hooks for latching the grounding wire operating rod. The three hooks are spaced apart on one side of the latching body, and the center lines of each hook are located in the same plane and are parallel to each other. The base part includes a base body and three sleeves for fitting the tail of the grounding wire operating rod. The three sleeves are spaced apart on one side of the base body, and the center lines of each sleeve are located in the same plane and are parallel to each other. The center lines of the three hooks are collinear with the center lines of the three sleeves, so that when the three-phase grounding wire is connected, the three grounding wire operating rods connected by the hooks and the sleeves are located in the same plane. The invention uses a snap-fit ​​part and a base part to fix the three grounding wire operating rods connected to the grounding wires into a whole, eliminating the need for grounding wire transmission and preventing the grounding wires from scattering during transmission. It also reduces the difficulty of installing and removing the grounding wires. The base part can be placed on the legs as a fulcrum, and the connecting parts can be held with both hands to shift the force point to the legs rather than the waist. The lever principle optimizes the operator's force application and installation distance, thereby protecting the operator's hands, waist, and other parts. Therefore, the invention can provide assistance in installing and removing grounding wires through the grounding wire operating rod to improve the convenience of operation, ensure the simultaneous connection of three-phase grounding wires, and make the grounding wire installation work more convenient, safe, and standardized.

Detailed Implementation

[0034] This invention provides an overhead grounding wire installation auxiliary device to solve the technical problem of how to provide assistance to improve the ease of operation when installing and removing grounding wires using a grounding wire operating rod.

[0035] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] In the description of this application, it should be noted that the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] This invention provides an auxiliary device for installing overhead grounding wires.

[0038] like Figure 1-3 As shown, the overhead grounding wire installation auxiliary device includes a buckle part 1, a connecting part 2, and a base part 3 connected in sequence;

[0039] The latching part 1 includes a latching body 11 and three hooks 12 for latching the grounding wire operating rod 4. The three hooks 12 are spaced apart on one side of the latching body 11, and the center lines of each hook 12 are located in the same plane and are parallel to each other.

[0040] The base part 3 includes a base body 31 and three sockets 32 for connecting the tail of the grounding wire operating rod 4. The three sockets 32 are spaced apart on one side of the base body 31, and the center lines of each socket 32 ​​are located in the same plane and are parallel to each other.

[0041] The center lines of the three hooks 12 are collinear with the center lines of the three sockets 32, so that when the three-phase grounding wire is connected, the three grounding wire operating rods 4 connected by the hooks 12 and the sockets 32 are located on the same plane.

[0042] When using the overhead grounding wire installation auxiliary device, the three grounding wire operating rods 4 of the three-phase grounding wire operating rods 4 can be snapped into the buckle part 1, and the tail of the three grounding wire operating rods 4 can be sleeved onto the sleeve part 32 of the base part 3, so that the three grounding wire operating rods 4 are fixed into a whole and kept on the same plane. When installing or removing the grounding wire, the base part 3 can be placed on the legs as a fulcrum, and the connecting part 2 can be held with both hands to hang the grounding wire of the three-phase grounding wire operating rods 4 onto the conductor.

[0043] In this embodiment of the invention, the three grounding wire operating rods 4 connected to the grounding wire are fixed as a whole by the buckle part 1 and the base part 3, so there is no need to transfer the grounding wire, thus avoiding the problem of the grounding wire scattering during the transfer process.

[0044] When installing three-phase grounding wires, since the three grounding wire operating rods 4 are fixed as a whole, there is no need to adjust the position of the grounding wires. The operator can use the connecting part 2 as a handle to operate the three grounding wire operating rods 4 by holding the connecting part 2, which reduces the difficulty of operating the grounding wires while wearing insulating gloves. Compared with the method of installing and removing the grounding wires without auxiliary devices, the difficulty of installing and removing the grounding wires is greatly reduced.

[0045] By placing the base 3 on the legs as a fulcrum and holding the connecting part 2 with both hands, the force point can be shifted to the legs rather than the waist. The lever principle is used to optimize the operator's force application and installation distance, thereby protecting the operator's hands, waist and other parts.

[0046] Therefore, the present invention can provide assistance to improve the ease of operation when installing and removing grounding wires through the grounding wire operating rod 4, ensuring that the three-phase grounding wires are connected at the same time, making the grounding wire installation work more convenient, safe and standardized.

[0047] To make it easier for operators to hold the connecting part 2, a handle can be further provided on the connecting part 2.

[0048] The connection between the hook 12 and the buckle body 11 can be detachable, fixed, or even integrally formed.

[0049] As one possible approach, the hook 12 is detachably connected to the buckle body 11 to facilitate replacement of the hook 12 in case of problems. The size of the hook 12 can also be set according to the diameter of the grounding wire operating rod 4. When the hook 12 is detachably connected to the buckle body 11, different sizes of hooks 12 can be set according to different grounding wire operating rods 4, so that the hook 12 that can be adapted to clamp the current grounding wire operating rod 4 can be selected by replacing the hook 12. In addition, the detachable connection between the hook 12 and the buckle body 11 also facilitates the phase-by-phase installation of the grounding wire.

[0050] When the hook 12 is detachably connected to the buckle body 11, in a specific embodiment, the hook 12 and the buckle body 11 are detachably connected by a buckle connection. For example... Figure 2 As shown, the buckle body 11 is provided with a first snap-fit ​​groove 111, and the hook 12 is provided with a first snap-fit ​​protrusion 121 that matches and connects with the first snap-fit ​​groove 111. It should be noted that a protrusion can also be provided on the buckle body 11, and a groove that matches and connects with the protrusion can be provided at the tail of the hook 12.

[0051] In another specific implementation, the hook 12 and the buckle body 11 are detachably connected by a threaded connection. Specifically, the hook 12 may have an external thread at its tail, and the buckle body 11 may have an internal thread matching the external thread. It should be noted that, alternatively, the hook 12 may have an internal thread at its tail, and the buckle body 11 may have an external thread matching the internal thread.

[0052] As another possible method, the hook 12 and the buckle body 11 are connected by a sliding groove. A concave groove is provided on the buckle body 11, and a sliding rod that matches the concave groove is provided on the tail of the hook 12. The two are connected in a detachable manner.

[0053] It should be noted that the detachable connection between the hook 12 and the buckle body 11 can also refer to other existing connection methods.

[0054] In one feasible manner, the socket 32 ​​is detachably connected to the base body 31.

[0055] Similarly, the connection between the socket 32 ​​and the base body 31 can be a detachable connection, a fixed connection, or even an integral molding.

[0056] As one possible approach, the socket 32 ​​is detachably connected to the base body 31 to facilitate replacement of the socket 32 ​​in case of problems. The size of the socket 32 ​​can also be set according to the diameter of the grounding wire operating rod 4. When the socket 32 ​​is detachably connected to the base body 31, different sized sockets 32 can be used for different grounding wire operating rods 4, allowing for the selection of a socket 32 ​​that is compatible with the current grounding wire operating rod 4 through replacement. Furthermore, the detachable connection between the socket 32 ​​and the base body 31 also facilitates the phase-by-phase installation of the grounding wire.

[0057] When the socket 32 ​​is detachably connected to the base body 31, in a specific embodiment, the socket 32 ​​and the base body 31 are detachably connected by a snap-fit ​​connection. For example... Figure 3 As shown, the base body 31 is provided with a second snap-fit ​​groove 311, and the socket 32 ​​is provided with a second snap-fit ​​protrusion 325 that matches and connects with the second snap-fit ​​groove 311. It should be noted that a protrusion can also be provided on the base body 31, and a groove that matches and connects with the protrusion can be provided at the tail of the socket 32.

[0058] In another specific implementation, the socket 32 ​​and the base body 31 are detachably connected by a threaded connection. Specifically, the socket 32 ​​may have an external thread at its tail, and the base body 31 may have an internal thread matching the external thread. It should be noted that, alternatively, the socket 32 ​​may have an internal thread at its tail, and the base body 31 may have an external thread matching the internal thread.

[0059] As another possible method, the socket 32 ​​and the base body 31 are connected by a sliding groove. A concave groove is provided on the base body 31, and a sliding rod that matches the concave groove is provided on the tail of the socket 32. The two are connected in a detachable manner.

[0060] It should be noted that the detachable connection between the socket 32 ​​and the base body 31 can also refer to other existing connection methods.

[0061] In one feasible way, such as Figure 4 , Figure 5 As shown, the socket 32 ​​is provided with an insert portion 321 for inserting the grounding wire operating rod 4 and a bottom portion 322 that can rotate along the socket hole;

[0062] The bottom portion 322 is provided with a socket groove 323 that connects to the tail of the grounding wire operating rod 4.

[0063] In this embodiment, since the connection between the socket groove 323 and the embedded part 321 on the bottom part 322 and the grounding wire operating rod 4 can fix the tail of the grounding wire operating rod 4, the grounding wire operating rod 4 can be tightened by rotating the bottom part 322.

[0064] In one feasible embodiment, the inner wall of the socket groove 323 is provided with a rubber protective material to increase the friction between the socket groove 323 and the grounding wire operating rod 4, thereby facilitating the tightening operation of the grounding wire operating rod 4.

[0065] In one feasible manner, the bottom surface of the bottom portion 322 is provided with a threaded hole 324 that matches a hexagonal screw.

[0066] In this embodiment, by setting the threaded hole 324, the grounding wire can be tightened using an electric wrench and a hexagonal socket, changing the manual tightening of the grounding wire operating rod 4 to electric tightening, effectively optimizing the grounding wire installation work.

[0067] In one feasible manner, the overhead grounding wire installation auxiliary device further includes an extension rod;

[0068] The extension rod is provided with a hexagonal screw that connects to the threaded hole 324.

[0069] In this embodiment, by setting an extension rod, the length of the grounding wire operating rod 4 for each phase can be increased, and the installation of the grounding wire at a distance can be directly achieved without moving the position of the auxiliary device on the grounding wire operating rod 4.

[0070] In one feasible embodiment, the connecting portion 2 is detachably connected to the snap-fit ​​portion 1 and / or the base portion 3. The detachable connection method can be referenced from the detachable connection method between the socket 32 ​​and the base body 31 described above, and will not be repeated here.

[0071] It should be noted that the connecting part 2 can also be detachably connected to the snap-fit ​​part 1 and / or the base part 3 by using an additional snap-fit ​​device.

[0072] In one feasible manner, the base body 31 is composed of three detachably connected base body 31 units, and each base body 31 unit is provided with a socket 32 ​​on one side.

[0073] In this embodiment, the base body 31 can be disassembled into individual base body 31 units, which is beneficial for the phase-by-phase installation of the grounding wire.

[0074] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
