Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and specifically to a device for disassembling a high-voltage cable T-type cable plug-in connector. Background Technology

[0002] Ring main units and cable branch boxes are the main power equipment of 10kV high-voltage cable lines. The cables are mainly connected to the ring main units and cable branch boxes by T-type cable plug-in joints. The T-type plug-in joints need to be disassembled during routine testing, maintenance and repair to separate the T-type cable plug-in joints from the cable pile head insulation sleeves.

[0003] T-type cable plug joints typically consist of a shielding layer and an insulation layer. The insulation material constituting the insulation layer is generally EPDM rubber or solid silicone rubber. When disassembling a T-type cable plug joint, because the connection between the T-type cable plug joint and the cable end insulating sleeve is tight, the traditional method of directly pulling it manually is time-consuming, labor-intensive, and inefficient. It may also damage the external insulation of the T-type cable plug joint, posing a safety hazard to the cable operation. Furthermore, pulling with ropes can damage the equipment panel, causing gaps between the panel and the cable end insulating sleeve.

[0004] To address the issue of manually disassembling T-type cable plugs, existing technologies have developed tools that can quickly disassemble T-type cable plugs, reducing the time-consuming, labor-intensive, and damaging problems associated with manual disassembly. However, these existing tools still rely on the pulling force generated during use to directly pull off the T-type cable plug, which still causes some damage to the T-type cable plug and requires considerable force. Summary of the Invention

[0005] To address the technical problem that existing tools capable of quickly disassembling T-type cable plugs rely on the pulling force generated during use to directly pull off the T-type cable plugs, which still causes some damage to the T-type cable plugs and requires considerable force, this invention provides a high-voltage cable T-type cable plug disassembly device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-voltage cable T-type cable plug-in connector disassembly device includes a connector sleeve, one end of which is used to fix and clamp the T-type cable plug-in connector, and the other end of which is coaxially connected to a nut. The nut can be detachably connected to a first disassembly component and a second disassembly component. The first disassembly component includes a wrench sleeve, one end of which is slotted to fit the nut, and the other end is coaxially connected to a wrench handle. The second disassembly component includes a lead screw, one end of which can be threadedly connected to the nut.

[0007] First, clamp one end of the connector sleeve to the rear of the T-type cable plug connector. Then, use the first disassembly tool to loosen the connection between the T-type cable plug connector and the cable post insulation sleeve. Next, use the second disassembly tool to pull the T-type cable plug connector with a smaller pulling force than existing technologies, so that the T-type cable plug connector is separated from the cable post insulation sleeve. This better protects the T-type cable plug connector, reduces damage to the T-type cable plug connector during disassembly, and is more convenient and labor-saving.

[0008] In a preferred embodiment of a high-voltage cable T-type cable plug-in connector disassembly device, the connector sleeve is an L-shaped structure adapted to the rear of the T-type cable plug-in connector. One end of the connector sleeve, used to clamp the T-type cable plug-in connector, has an opening for the T-type cable plug-in connector to be fitted onto the rear of the connector. A latch is provided on the lower side of the opening. By aligning one end of the opening with the rear of the T-type cable plug-in connector, the connector sleeve is fitted over the rear of the T-type cable plug-in connector, and then the latch is engaged, thus fixing the T-type cable plug-in connector in place.

[0009] As a preferred implementation of a high-voltage cable T-type cable plug-in connector disassembly device, one end of the buckle is rotatably connected to the connector sleeve, and the connector sleeve has a connecting buckle at the other end of the buckle. The connecting buckle engages with the buckle, and the buckle has an arc-shaped structure.

[0010] In a preferred embodiment of a high-voltage cable T-type cable plug-in connector disassembly device, the first disassembly component includes an electric wrench. A first connector is coaxially connected to the end of the wrench handle away from the wrench sleeve. The first connector can engage with the head sleeve of the electric wrench. By engaging the head sleeve of the electric wrench with the outside of the first connector and activating the electric wrench, the head sleeve rotates alternately in both forward and reverse directions. This allows for alternating forward and reverse rotation of the wrench handle along its circumferential direction, enabling faster and more convenient loosening of the T-type cable plug-in connector and ensuring more even force distribution on the connector.

[0011] In a preferred embodiment of a high-voltage cable T-type cable plug-in connector disassembly device, the wrench lever is detachably connected to the first connector. This facilitates the replacement and maintenance of the first connector and ensures that the first connector and the head sleeve are compatible.

[0012] In a preferred embodiment of a high-voltage cable T-type cable plug-in connector disassembly device, a second connector is coaxially connected to the other end of the lead screw. This second connector can be engaged with the head sleeve of an electric wrench. By engaging the head sleeve of the electric wrench with the second connector and activating the electric wrench, the lead screw can be rotated, allowing for easier and less strenuous pulling out of the T-type cable plug-in connector, and resulting in more even force distribution on the connector.

[0013] As a preferred implementation of a high-voltage cable T-type cable plug-in connector disassembly device, the bottom of the electric wrench is detachably connected to the top of the extension arm, and the bottom of the extension arm is connected to the base. During use, the bottom of the extension arm is supported on the ground, and the worker squats or sits down, using their legs to clamp and secure the extension arm, improving the stability of the electric wrench during operation, enhancing work quality, and further protecting the T-type cable plug-in connector.

[0014] In a preferred embodiment of a high-voltage cable T-type cable plug-in connector disassembly device, an electric wrench is connected to an inverter power supply. A portable power source is provided for convenient use when no power outlet is available.

[0015] As a preferred implementation of a high-voltage cable T-type cable plug-in connector disassembly device, a first connecting hole is opened at the end of the wrench lever away from the wrench sleeve. The first connecting hole is perpendicular to the axial direction of the wrench lever, and a first torsion bar is detachably sleeved in the first connecting hole. When the first torsion bar is inserted into the first connecting hole, the first torsion bar is perpendicular to the wrench lever. Rotating the first torsion bar makes it easier for the wrench lever to drive the wrench sleeve and nut to rotate in the forward and reverse directions in the circumferential direction, requiring less effort.

[0016] As a preferred implementation of a high-voltage cable T-type cable plug-in connector disassembly device, a second connecting hole is opened at the other end of the lead screw. The second connecting hole is perpendicular to the axial direction of the lead screw, and a second torsion bar is detachably sleeved in the second connecting hole. Inserting the second torsion bar into the second connecting hole, with the second torsion bar perpendicular to the lead screw, allows for easier circumferential rotation of the lead screw to screw into the nut, requiring less effort.

[0017] The beneficial effects of this invention include: 1. Simple to operate In use, first, fix one end of the connector sleeve to the rear of the T-type cable plug-in connector. Then, use the wrench sleeve in the first disassembly part to fit around the nut of the connector sleeve. Rotate the wrench lever alternately in the forward and reverse directions along the circumferential direction of the wrench lever to loosen the T-type cable plug-in connector. Then, remove the first disassembly part.

[0018] Using the screw from the second disassembly component, screw it into the nut. The screw and nut are threaded together. After the end of the screw is screwed into the connector sleeve and abuts against the end of the T-type cable plug connector, continue to screw the screw. Since the previous step has already loosened the T-type cable plug connector, continuing to screw the screw, with the end of the screw already abutting against the end of the T-type cable plug connector, can pull the T-type cable plug connector and separate it from the cable post insulation sleeve.

[0019] 2. Facilitates protection of T-type cable plug-in connectors Compared to existing technologies that directly pry or pull open the T-type cable plug connector to separate it from the cable post insulation sleeve, potentially damaging the rubber sealant and compromising the outer insulation, this invention first loosens the connection between the T-type cable plug connector and the cable post insulation sleeve. Then, it uses a smaller pulling force than existing technologies to pull the T-type cable plug connector, separating it from the cable post insulation sleeve. This provides better protection for the T-type cable plug connector, reduces damage during disassembly, and is more convenient and labor-saving. Attached Figure Description

[0023] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example 1: Reference Figure 1 In the existing technology, the T-type cable plug connector 5 and the cable post insulating sleeve 6 are tightly connected. Traditional manual pulling may damage the external insulation of the T-type cable plug connector 5, which is not only inefficient but also poses a safety hazard. The existing tools for quickly disassembling the T-type cable plug connector 5 also involve covering the T-type cable plug connector 5 and then using the tool to generate a pulling force perpendicular to the mounting surface (the surface on which the cable post insulating sleeve 6 is mounted on the equipment). A large pulling force is used to pull apart the T-type cable plug connector 5 and the cable post insulating sleeve 6. Although this method improves efficiency, it is still easy to damage the external insulation of the T-type cable plug connector 5.

[0025] Based on this, this embodiment proposes a device for disassembling a high-voltage cable T-type cable plug-in connector.

[0026] Reference Figure 2-6 and Figure 8 This embodiment proposes a high-voltage cable T-type cable plug-in connector disassembly device, including a connector sleeve 1. One end of the connector sleeve 1 is used to fix and clamp the T-type cable plug-in connector 5, and the other end of the connector sleeve 1 is coaxially connected to a nut 2. The nut 2 can be detachably connected to a first disassembly component 3 and a second disassembly component 4 respectively. The first disassembly component 3 includes a wrench sleeve 31. One end of the wrench sleeve 31 is slotted to fit the nut 2, and the other end is coaxially connected to a wrench handle 32. The second disassembly component 4 includes a lead screw 41. One end of the lead screw 41 can be threadedly connected to the nut 2.

[0027] In use, firstly, fix one end of the connector sleeve 1 to the rear of the T-type cable plug connector 5. Then, use the wrench sleeve 31 in the first disassembly part 3 to fit outside the nut 2 of the connector sleeve 1. Rotate the wrench rod 32 alternately in the forward and reverse directions along the circumferential direction of the wrench rod 32 to loosen the T-type cable plug connector 5. Then, remove the first disassembly part 3.

[0028] Using the second disassembly part 4, screw the lead screw 41 into the nut 2. The lead screw 41 is threadedly connected to the nut 2. After the end of the lead screw 41 is screwed into the connector sleeve 1 and abuts against the end of the T-type cable plug connector 5, continue to screw the lead screw 41. Since the previous step has already loosened the T-type cable plug connector 5, continuing to screw the lead screw 41 can pull the T-type cable plug connector 5 and separate the T-type cable plug connector 5 from the cable post insulation sleeve 6, even though the end of the lead screw 41 is already abutting against the end of the T-type cable plug connector 5.

[0029] Compared to existing technologies that directly pry open or pull the T-type cable plug connector 5 to separate it from the cable post insulating sleeve 6, which may damage the rubber T-type cable plug connector 5 and destroy the outer insulation, this embodiment first loosens the connection between the T-type cable plug connector 5 and the cable post insulating sleeve 6, and then uses a smaller pulling force than existing technologies to pull the T-type cable plug connector 5 to separate it from the cable post insulating sleeve 6. This can better protect the T-type cable plug connector 5, reduce damage to the T-type cable plug connector 5 during disassembly, and is more convenient and labor-saving.

[0030] Example 2: This embodiment proposes a device for disassembling a high-voltage cable T-type cable plug-in connector. This embodiment is based on Embodiment 1 and refers to... Figure 2-4 and Figure 8 In this embodiment, the connector sleeve 1 of the high-voltage cable T-type cable plug-in connector disassembly device is an L-shaped structure adapted to the rear of the T-type cable plug-in connector 5. The connector sleeve 1 has an opening 11 at one end for fixing and clamping the T-type cable plug-in connector 5. The opening 11 is used to access the rear of the T-type cable plug-in connector 5 (i.e.,...) Figure 1 The left end of the T-type cable plug-in connector 5 is connected to the insulating sleeve 6 of the cable post head. The connector sleeve 1 has a buckle 12 on the lower side of the opening 11. The top of the end of the connector sleeve 1 used to fix and clamp the T-type cable plug-in connector 5 has a first notch 14. The bottom of the end face of the connector sleeve 1 with the nut 2 has a second notch 15. The bottom of the connector sleeve 1 opposite to the opening 11 has a third notch 16. The width of the third notch 16 is smaller than the diameter of the bottom column of the T-type cable plug-in connector 5. The design of the first notch 14, the second notch 15 and the third notch 16 notches not only facilitates the user to observe the connection between the connector sleeve 1 and the T-type cable plug-in connector 5, but also reduces the material cost of the connector sleeve 1.

[0031] Align one end of the opening 11 with the rear of the T-type cable plug-in connector 5, so that the connector sleeve 1 covers the rear of the T-type cable plug-in connector 5, and then lock the buckle 12 to fix the connector sleeve 1 in place and hold the T-type cable plug-in connector 5.

[0032] Furthermore, one end of the buckle 12 is rotatably connected to the connector sleeve 1, and the connector sleeve 1 has a connecting buckle 13 at the other end of the buckle 12. Rotating the buckle 12 can engage the buckle 12 with the connecting buckle 13. The buckle 12 has an arc-shaped structure. The buckle 12 fits more snugly with the T-type cable plug connector 5.

[0033] Example 3: This embodiment proposes a device for disassembling a high-voltage cable T-type cable plug-in connector. This embodiment is based on Embodiment 1. The first disassembly component 3 includes an electric wrench. Figure 5 (not shown in the image), see reference. Figure 5 The end of the wrench handle 32 away from the wrench sleeve 31 is coaxially connected to a first connector. The first connector can be sleeved with the head sleeve of the electric wrench. The first connector can be a hexagonal nut. The head sleeve of the electric wrench can be sleeved on the outside of the first connector.

[0034] An electric wrench is an electric tool used to tighten and loosen bolts and nuts. Electric wrenches usually have a forward and reverse power switch, such as an impact wrench.

[0035] Reference Figure 5 ,based on Figure 5 In the direction of the wrench lever 32, the left end is the first connector and the right end is the wrench sleeve 31.

[0036] The head socket of the electric wrench is fitted onto the outside of the first connector. The electric wrench is started, and the head socket of the electric wrench rotates alternately in both forward and reverse directions. This allows the wrench rod 32 to be rotated alternately in both forward and reverse directions along the circumferential direction, which can loosen the T-type cable plug connector 5 more quickly and conveniently, and make the force on the T-type cable plug connector 5 more even.

[0037] Furthermore, the wrench handle 32 is detachably connected to the first connector. This facilitates the replacement and maintenance of the first connector and ensures that the first connector and the head sleeve are compatible.

[0038] Furthermore, referring to Figure 7 The bottom of the electric wrench is detachably connected to the top of the extension arm 33, and the bottom of the extension arm 33 is connected to the base 34. In use, the bottom of the extension arm 33 is supported on the ground, and the worker squats or sits down, using their legs to clamp and secure the extension arm 33, improving the stability of the electric wrench during operation, enhancing work quality, and further protecting the T-type cable plug connector 5.

[0039] Furthermore, the electric wrench is connected to an inverter power supply. A portable power source is included for easy portability.

[0040] This embodiment can be implemented together with Embodiment 2.

[0041] Example 4: This embodiment proposes a device for disassembling a high-voltage cable T-type cable plug-in connector. This embodiment is based on Embodiment 1, and the second disassembly component 4 includes an electric wrench. Figure 6 (not shown in the image), see reference. Figure 6 The other end of the lead screw 41 (i.e. Figure 6 The left end of the lead screw 41 is coaxially connected to a second connector. The second connector can be fitted with the head sleeve of the electric wrench. The second connector can be a hexagonal nut. The head sleeve of the electric wrench can be fitted onto the outside of the second connector.

[0042] When the head socket of the electric wrench is fitted onto the outside of the second connector, the electric wrench is started, and the screw 41 can be rotated, which makes it easier and less strenuous to pull out the T-type cable plug connector 5, and makes the force on the T-type cable plug connector 5 more even.

[0043] This embodiment can be implemented together with Embodiments 2 and 3, and can share an electric wrench with Embodiment 3.

[0044] Example 5: This embodiment proposes a high-voltage cable T-type cable plug-in connector disassembly device. This embodiment is based on Embodiment 1. The end of the wrench rod 32 away from the wrench sleeve 31 has a first connecting hole. The first connecting hole is perpendicular to the axial direction of the wrench rod 32. A first torsion bar is detachably sleeved in the first connecting hole.

[0045] Insert the first torsion bar into the first connecting hole. The first torsion bar is perpendicular to the wrench lever 32. Rotating the first torsion bar makes it easier for the wrench lever 32 to drive the wrench sleeve 31 and nut 2 to rotate in the forward and reverse directions in the circumferential direction, which is more labor-saving.

[0046] This embodiment can be implemented together with Embodiments 2, 3, and 4.

[0047] Example 6: This embodiment proposes a high-voltage cable T-type cable plug-in connector disassembly device. This embodiment is based on embodiment one. The other end of the lead screw 41 has a second connecting hole, which is perpendicular to the axial direction of the lead screw 41. A second torsion bar is detachably sleeved in the second connecting hole.

[0048] Insert the second torsion bar into the second connecting hole. The second torsion bar is perpendicular to the lead screw 41. Rotating the second torsion bar makes it easier to rotate the lead screw 41 in the circumferential direction to screw it into the nut 2, which is less strenuous.

[0049] This embodiment can be implemented together with Embodiments 2, 3, 4, and 5.

[0050] All permutations and combinations of the above-described embodiments 1, 2, 3, 4, and 5 fall within the protection scope of this invention.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
