[0002] In power systems, cables are a crucial component for transmitting electrical energy, and their quality and performance directly affect the safety and reliability of power supply. To ensure the normal operation of cables, various tests must be conducted on them regularly, including routine tests, sampling tests, type tests, acceptance tests, and preventative tests. Among these, acceptance tests and preventative tests are particularly important for cable construction and maintenance departments. Cable T-joints are key devices installed at the beginning and end of cable lines, primarily used to connect with other electrical equipment and to even out the electric field distribution at the cable end, effectively controlling electrical stress and improving the reliability of cable operation.

[0003] However, in practice, the large friction between the T-head and the base makes the disassembly process time-consuming, affecting work efficiency. Furthermore, the need for multiple non-specialized tools increases the complexity and time cost of the operation, making the process of removing the cable terminal T-head complex and time-consuming. Utility Model Content

[0004] The purpose of this utility model is to provide a cable T-head disassembly tool, which can avoid the situation where the disassembly process is time-consuming due to the large friction between the T-head and the base, which affects work efficiency. Secondly, it requires the use of multiple non-specialized tools, which increases the complexity and time cost of operation, making the process of removing cable terminal T-heads complicated and time-consuming.

[0005] This utility model provides a cable T-head disassembly tool, including a metal beam.

[0015] This utility model provides a cable T-joint disassembly tool, which, compared with the prior art, offers the following advantages:

[0016] 1. This utility model fixes the first and second retaining rings to the cable T-head and adjusts the positions of the two sets of metal rods according to the size of the first and second retaining rings, so that the hooks hook the first and second retaining rings. By rotating the set screw with an electric wrench or a manual wrench, the metal beam moves along with the metal rods, the first retaining ring and the second retaining ring, which in turn moves the cable T-head, allowing for quick disassembly. This eliminates the need for multiple disassembly tools required by traditional disassembly methods, saving time and effort.

[0017] 2. This utility model allows the sliding of the connecting piece within the groove to adjust the position of the two sets of metal rods as needed. It can fix different sizes of retaining rings one and two. The use of side blocks, buckles, buckle plates, and hook plates to form a buckle facilitates the disassembly of retaining rings one and two, further saving operation time.

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please refer to Figures 1-8This utility model provides a cable T-head disassembly tool, including a metal beam 1 made of cold-rolled steel. A threaded sleeve 3 is provided in the middle of the metal beam 1, and a set screw 4 is internally threaded into the threaded sleeve 3. Fixing components are slidably installed on both sides of the metal beam 1. When disassembling the cable T-head, the positioning component is sleeved on the cable T-head, and the two sets of fixing components fix the two sides of the positioning component. The set screw 4 is rotated using an electric wrench or a manual wrench. A sleeve block 5 is fixedly provided at the upper end of the set screw 4. The sleeve block 5 is easy to connect with the electric wrench or manual wrench, causing the two sets of fixing components to move the positioning component and the cable T-head, thereby realizing the disassembly of the cable T-head. This method eliminates the need for a series of disassembly tools and saves disassembly time.

[0031] The fixing component includes a connector 6, with symmetrical protrusions 7 arranged on the inner side of the connector 6. There is a gap between the symmetrical protrusions 7, and symmetrical extension sides 2 are arranged on both sides of the metal beam 1. A sliding groove 18 is formed between the symmetrical extension sides 2. The protrusions 7 on both sides slide in the sliding grooves 18 on both sides. By sliding the connector 6, the distance between the two sets of connectors 6 is adjusted. At the same time, a top block 9 is fixed inside the connector 6 by bolts 10. The lower end of the top block 9 is connected to a metal rod 8. The lower end of the metal rod 8 is provided with a hook 19. The two sets of hooks 19 are fixed on both sides of the positioning component so that the metal rod 8 and the hooks 19 can drive the positioning component to move when the metal beam 1 moves.

[0032] To accommodate the use of cable T-type connectors, the length of the metal beam 1 is 200mm, and the total length of the metal rod 8 and the hook 19 is 160mm.

[0033] In addition, the positioning assembly includes a first retaining ring 11 and a second retaining ring 12, which are hinged together by a hinge 13. Both retaining rings 11 and 12 are semi-circular rings and can move freely through the hinge 13. The retaining rings 11 and 12 are fitted onto the cable T-head. A side block 14 is installed on the other side of the retaining ring 11, and a buckle 15 is rotatably provided on the side block 14. A buckle plate 16 is fixedly provided at the other end of the side block 14. A hook plate 17 is provided on one side of the second retaining ring 12. The retaining ring 15 is fastened to the hook plate 17, and the retaining rings 11 and 12 are fixed to the cable T-head, which facilitates the hook 19 to fix the retaining rings 11 and 12.

[0034] Among them, the metal beam 1, metal rod 8 and hook 19 are all made of cold-rolled steel, and the first circlip 11 and the second circlip 12 are made of nylon to avoid damage to the cable T-head.

[0035] The inner sides of the retaining rings 11 and 12 are provided with anti-slip pads 20 to further prevent slipping. In addition, after the retaining rings 11 and 12 are fixed to the cable T-head, the gap between them and the cable T-head is less than 1mm, ensuring the stability of the cable T-head after fixing.

[0036] In summary, the working principle of the cable T-head disassembly tool of this utility model embodiment is as follows: Clamping ring 11 and clamping ring 2 12 are unfolded via hinge 13 and fitted onto the cable T-head. The buckle 15 on the side block 14 is fastened to the hook plate 17 on one side of clamping ring 2 12, ensuring the clamping ring is firmly fixed to the cable T-head. The sliding connector 6 is used to adjust the distance between the two sets of connectors 6, allowing the hook 19 to accurately hook clamping ring 11 and clamping ring 2 12. An electric or manual wrench is connected to the sleeve block 5 at the upper end of the set screw 4. Rotating the set screw 4 clockwise with the electric or manual wrench causes the fixing parts on both sides of the metal beam 1 to move the connector 6, metal rod 8, and hook 19. With the rotation of the set screw 4, the metal beam 1 and the two sets of hooks 19 move clamping ring 11 and clamping ring 2 12, thereby pushing the cable T-head along a predetermined direction for rapid disassembly.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
