Description

Technical Field

[0001] This invention relates to the field of power maintenance tools, and more particularly to an auxiliary tool for riveting high-voltage cable joints. Background Technology

[0002] Due to installation methods and limited space, some high-voltage cables require riveting at two points at the cable joint, such as... Figure 1 As shown, during riveting operations, a 1mm space needs to be left below the rivet on the high-voltage cable connector. Currently, when installing rivets, a flat-head screwdriver is placed below the rivet hole, the rivet is placed above the rivet hole, and then hammered in. However, when using the above method for riveting, inserting the flat-head screwdriver can easily increase the space required for the rivet, such as... Figure 2 As shown, this results in excessive rivet residue when the rivet is engaged, making it impossible for the flathead screwdriver to fit into the space when riveting the other side.

For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from this disclosure.

[0040] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the device structure closely related to the solution according to the invention is shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0041] like Figures 3 to 5 As shown, an embodiment of the present invention provides a high-voltage cable joint rivet auxiliary tool, including: an upper pad 1, a first grip ring 14, a lower pad 2, and a second grip ring 24. The upper pad 1 includes an upper rivet pad 11 and an upper handle, and the lower pad 2 includes a lower rivet pad 21 and a lower handle.

[0042] The upper pad 1 and the lower pad 2 are movably connected by the first grip ring 14 and the second grip ring 24;

[0043] When the upper pad 1 and the lower pad 2 are closed by the first grip ring 14 and the second grip ring 24, the upper rivet pad 11 and the lower rivet pad 21 form an opening below the rivet hole of the high-voltage cable connector and extend a predetermined length toward the rivet hole of the high-voltage cable connector 3. The upper grip and the lower grip form a receiving cavity for accommodating the components of the high-voltage cable connector 3. The upper pad 1 and the lower pad 2 form a through slot along the extending direction of the upper rivet pad 11 and the lower rivet pad 21 so that the wiring of the high-voltage cable connector 3 can pass through.

[0044] An auxiliary tool for riveting high-voltage cable joints according to an embodiment of the present invention mainly includes two parts: an upper pad 1 and a lower pad 2. One end of the upper pad 1 is an upper rivet pad 11, which can be inserted under the rivet hole of the high-voltage cable joint 3 to prepare for the riveting process; the other end is connected to a first gripping ring 14 and is movably connected to the lower pad 2 through a second gripping ring 24. Figures 3-10 In the middle, the first grip ring 14 can be called the upper grip ring, and the second grip ring 15 can be called the lower grip ring. Figure 11-15 and Figure 17 In this invention, the first grip ring 14 (which can be called the left grip ring) and the second grip ring 15 (which can be called the right grip ring) allow the upper pad 1 and the lower pad 2 to open and close easily, facilitating the placement of the high-voltage cable connector and not affecting the cable wiring of the high-voltage cable connector 3. The upper pad 1 has an upper handle in the middle, which facilitates pressing the high-voltage cable connector riveting auxiliary tool during the riveting process, preventing rivet misalignment. The structure of the lower pad 2 is similar to that of the upper pad 1, consisting of a lower rivet pad 21 and a lower handle; the lower pad 2 and the upper pad 1 are movably connected by the first grip ring 14 and the second grip ring 24. The high-voltage cable connector riveting auxiliary tool of this embodiment allows the high-voltage cable connector 3 to be riveted by having both upper and lower rivet pads simultaneously inserted into the pad space, avoiding the problem in related technologies where simple tools prevent riveting on one side.

[0045] like Figures 4 to 5 As shown in the embodiment of the present invention, the upper grip includes an upper step portion 12 and an upper support bar 13; the lower grip includes a lower step portion 22 and a lower support bar 23. The upper step portion 12 is connected to the upper rivet pad 11, the upper support bar 13 is connected to the upper step portion 12, the lower step portion 22 is connected to the lower rivet pad 21, and the lower support bar 23 is connected to the lower step portion 22. The upper rivet pad 11 and the lower rivet pad 21 are symmetrically arranged, the upper step portion 12 and the lower step portion 22 are symmetrically arranged, and the upper support bar 13 and the lower support bar 23 are symmetrically arranged. When the upper pad 1 and the lower pad 2 are closed by the first grip ring 14 and the second grip ring 24, a receiving cavity for accommodating the component of the high-voltage cable connector 3 is formed between the upper step portion 12 and the lower step portion 23.

[0046] In this embodiment of the invention, the upper pad 1 includes an upper handle, which includes an upper support bar 13 and is provided with an upper step portion 12. The lower pad 2 includes a lower handle, which includes a lower support bar 23 and is provided with a lower step portion 22. This facilitates avoiding the knurled nut 4 of the high-voltage cable connector 3 when performing the riveting process and prevents the rivet from being misaligned.

[0047] like Figure 3 and Figure 6 As shown in the embodiment of the present invention, the first grip ring 14 includes a first handle and a first connecting part, and the second grip ring 24 includes a second handle and a second connecting part. The first connecting part and the second connecting part are movably connected by a hinge. When the upper pad 1 and the lower pad 2 are closed by the first grip ring 14 and the second grip ring 24, the first handle and the second handle may or may not be in contact.

[0048] In this embodiment of the invention, the upper pad 1 and the lower pad 2 can be opened and closed well through the handle (including two handles: a first handle and a second handle) and the connecting part (including two connecting parts: a first connecting part and a second connecting part). When the first handle of the first grip ring 14 and the second handle of the second grip ring 24 come into contact, the first grip ring 14 and the second grip ring 24 can form a complete closed structure. This makes the high-voltage cable joint riveting auxiliary tool more stable and reliable when the upper pad 1 and the lower pad 2 are closed by the first grip ring 14 and the second grip ring 24.

[0049] In this embodiment of the invention, the first handle is an annular handle, the second handle is an annular handle, and when the upper pad 1 and the lower pad 2 are closed by the first grip ring 14 and the second grip ring 24, the first handle and the second handle form a ring.

[0050] In this embodiment of the invention, the cross-sectional shape of the connecting hole for hinged connection between the first connecting part and the second connecting part is a combination of circular, elliptical, rounded rectangle, straight line and / or arc shape.

[0051] When the cross-sectional shape of the connecting hole used for hinged connection between the first connecting part and the second connecting part is circular, the first gripping ring 14 and the second gripping ring 24 can be movably connected by screws and nuts. The first gripping ring 14 and the second gripping ring 24 can rotate and open and close around the screw as an axis, which facilitates the placement of high-voltage cable connectors.

[0052] like Figures 7 to 10 As shown, when the cross-sectional shape of the connecting hole for hinged connection of the first connecting part and the second connecting part is elliptical, rounded rectangle or approximately racetrack shape, the screw and nut for movable connection can move within the connecting hole. Therefore, the first grip ring 14 and the second grip ring 24 can rotate and open with the screw as the axis, and can also adjust their position in the vertical direction to realize the adjustment and switching of high voltage cable connectors 3 of different sizes or diameters and cable wiring.

[0053] The cross-sectional shape of the connecting hole used for hinged connection between the first connecting part and the second connecting part can be other shapes formed by a combination of straight lines and / or arcs.

[0054] As described above, in this embodiment of the invention, the first handle and the second handle may not contact each other, and their positions may be adjusted in the vertical direction to achieve adjustment and switching of high-voltage cable connectors and cable wiring of different sizes or diameters.

[0055] like Figures 11 to 17 The diagram shows another structural schematic of a special tool for riveting high-voltage cable joints according to an embodiment of the present invention. Figures 3 to 10 The difference between the special tools shown for the high-voltage cable joint riveting process is that... Figures 3 to 10 The special tool for riveting high-voltage cable joints in China is a side-opening type. Figures 11 to 17 The special tool used in the high-voltage cable joint riveting process is an up-and-down opening tool. Figures 3 to 10 The special tool for riveting high-voltage cable joints has the following characteristics: the extension plane of the first connecting part is parallel to or coincides with the plane of the first handle; the extension plane of the second connecting part is parallel to or coincides with the plane of the second handle; and the pivot of the hinge between the first connecting part and the second connecting part is parallel to the extension direction of the high-voltage cable and perpendicular to the plane of the first grip ring 14 and the second grip ring 24. Figures 11 to 17 This is a special high-voltage cable connector riveting process. The pivot shaft that is hinged between the first connecting part and the second connecting part is perpendicular to the extension direction of the high-voltage cable. There are two first connecting parts, located on both sides of the first handle, and two second connecting parts, located on both sides of the second handle. The two first connecting parts are movably connected to the two second connecting parts respectively.

[0056] In this embodiment of the invention, the pins used for hinged connection between the first connecting part and the second connecting part are pan head screws and hexagonal nuts.

[0057] Specifically, the first gripping ring 14 and the second gripping ring 24 are connected by GBT818 cross-grooved pan head screws and GB-T6170 hexagonal nuts.

[0058] In this embodiment of the invention, the upper rivet pad 11 and the lower rivet pad 21 are planar, arc-shaped, or wedge-shaped structures.

[0059] The upper rivet pad 11 and the lower rivet pad 21 can be arc surfaces to adapt to high-voltage cable joints of corresponding sizes and diameters. In this embodiment of the invention, in order to adapt to high-voltage cable joints of different sizes or diameters, the upper rivet pad 11 and the lower rivet pad 21 can be flat surfaces.

[0060] like Figures 11 to 13 As shown, the special tool for rivetizing high-voltage cable joints is designed to open and close from top to bottom. In order to accommodate high-voltage cable joints 3 of different sizes or diameters, the upper rivet pad 11 and the lower rivet pad 21 are set as wedges, that is, the side facing the rivet hole of the high-voltage cable joint is thin or the side away from the upper or lower handle is thin (the front end is thin), and the side away from the rivet hole of the high-voltage cable joint 3 is thick or the side connected to the upper or lower handle is thick (the rear end is thick).

[0061] In this embodiment of the invention, the thickness of the upper rivet pad 11 and the lower rivet pad 21 is less than 1 mm.

[0062] In this embodiment of the invention, the upper rivet pad 11, the upper grip and the first grip ring 14 are an integral structure, and the lower rivet pad 21, the lower grip and the second grip ring 24 are an integral structure.

[0063] like Figure 6 As shown in the figure, this embodiment of the invention also provides a method for riveting a high-voltage cable joint, comprising:

[0064] The upper pad 1 and the lower pad 2 are brought together on the cable of the high-voltage cable joint by the first gripping ring 14 and the second gripping ring 24, so that the upper step 12 and the lower step 22 are on the knurled nut of the high-voltage cable joint.

[0065] Push the high-voltage cable joint rivet auxiliary tool so that the upper rivet pad 11 and the lower rivet pad 21 are below the rivet hole;

[0066] Place the rivet above the rivet hole and hammer it in place.
