Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet maintenance, in particular to a quick elbow-type cable head extraction device. Background Art

[0002] During equipment maintenance and testing, the cable and the equipment need to be separated. However, after a period of operation, the plug-in cable terminal will generate heat due to the passage of current. Thermal expansion and contraction will cause the silicone grease to generate a strong grip between the plug-in cable terminal and the equipment casing, making disassembly difficult. The disassembly process can easily damage the silicone grease protective layer on the outer surface, and thus a device is needed to quickly pull out the elbow-type cable head.

[0003] Reference may be made to an existing document for an elbow-type cable head wrapped removal tool (CN210016191U), which provides two forces on the elbow-type cable head through a vertical circular ring buckle and a horizontal circular ring buckle, thereby preventing the elbow-type cable head from being damaged due to a single force during the removal process.

[0004] In the prior art, as shown in the above-mentioned literature, a clamping structure is usually provided to fix the elbow-type cable head, and then the clamping part is connected to the hydraulic part to achieve the clamping of the cable terminal head. The hydraulic cylinder is used to drive the clamping structure to move, and then drive the plug-in cable terminal head to pull it out. This design is often for the disassembly of a single elbow-type cable head. When disassembling multiple groups of elbow-type cable heads, it is necessary to continuously disassemble the clamping structure to remove the elbow-type cable head, and then put it into other elbow-type cable heads for positioning and installation. Continuous disassembly and positioning will consume a lot of maintenance time. Therefore, a device for pulling out an elbow-type cable head that is easy to position and fix is ​​now designed.

[0005] The purpose of the present invention is to address the shortcomings of the prior art and to propose a quick elbow cable head extraction device. During the extraction process, the elbow cable head can be fixed by a locking assembly, and then quickly extracted by the operation of a hydraulic rod. At the same time, the device can achieve rapid positioning through the reverse movement of the two locking assemblies, and the position can be adjusted by the lateral movement of the locking assembly. The elbow cable heads in the same row can be removed one by one, eliminating the need for personnel to constantly disassemble and position them, thereby improving maintenance efficiency.

[0027] Referring to Figure 1-4 , the quick elbow cable head pulling device comprises an adjusting seat 1, a hydraulic rod 2, a positioning seat 3 and a locking assembly. The adjusting seat 1 is internally provided with a slider I 9 capable of moving linearly in the transverse direction. The front end of the slider I 9 is fixed with the hydraulic rod 2. The telescopic end of the hydraulic rod 2 is fixed with the positioning seat 3. The positioning seat 3 is internally provided with two sliders II 12 capable of moving in opposite directions. The front ends of the two sliders II 12 are connected with the locking assembly. The device can clamp and fix the two ends of the elbow cable head 4 through the two symmetrically designed locking assemblies, and then pull out the elbow cable head 4 through the operation of the hydraulic rod 2. The opposite movement of the two sliders II 12 can drive the opposite movement of the two locking assemblies, thereby quickly positioning the elbow cable head 4. The transverse movement of the slider I 9 can make the two locking assemblies as a whole to be adjusted in the transverse position, thereby adjusting according to the position of the elbow cable head 4, and facilitating the installation and positioning of the elbow cable head 4.

[0028] Specifically, as shown in Figure 1-2 , an installation plate 6 is integrally connected to the outside of the adjusting seat 1. The adjusting seat 1 is fixed on the surface of the power distribution cabinet through the installation plate 6. The locking assembly is positioned and fixed through the hole position on the installation plate 6, and is directed towards the inside of the power distribution cabinet.

[0029] Further, as shown in Figure 2 , a one-way screw rod 8 is rotatably connected in the adjusting seat 1. The one-way screw rod 8 is externally threaded with the slider I 9. Meanwhile, a motor I 7 is installed at one end of the adjusting seat 1. The output end of the motor I 7 is fixed with the one-way screw rod 8.

[0030] In this embodiment, the rotation of the one-way screw rod 8 is driven by the operation of the motor I 7, so that the slider I 9 externally threaded with the one-way screw rod 8 moves linearly in the adjusting seat 1.

[0031] Specifically, as shown in Figure 3 , a bidirectional screw rod 11 is rotatably connected in the positioning seat 3. The bidirectional screw rod 11 is externally threaded with two sliders II 12. The two sliders II 12 are symmetrically distributed at the center of the bidirectional screw rod 11. Meanwhile, a motor II 10 is installed at one end of the positioning seat 3. The output end of the motor II 10 is fixed with the bidirectional screw rod 11.

[0032] In this embodiment, the operation of the second motor 10 drives the bidirectional screw rod 11 to rotate, thereby causing the two outer sliders 2 12 to move in opposite directions about the center of the bidirectional screw rod 11 .

[0033] For details, please refer to Figure 4 The locking assembly includes a fixed bracket 13, which is L-shaped and installed at the front end of the slider 2 12, and the other end is fixed to the splint 1 5 in the locking assembly. The locking assembly also includes a splint 2 14 and a docking plate 15. Both the splint 2 14 and the splint 1 5 are arc-shaped and the splint 2 14 is rotatably connected to the top of the splint 1 5, and the docking plate 15 is rotatably connected to the other end of the splint 2 14.

[0034] In this embodiment, the two clamps 1 5 and 14 are driven to move in opposite directions by the fixed bracket 13, so that the clamps 1 5 and 14 are tightly attached to the two ends of the elbow-shaped cable head 4 and provide clamping force. The rotation of the clamp 2 14 can be adjusted according to the diameter of the elbow-shaped cable head 4. The rotation of the docking plate 15 makes the connecting screw holes 16 on the surface of the docking plate 15 aligned, and bolts are installed in the connecting screw holes 16 of the two docking plates 15, and bolts are installed in the connecting screw holes 16 on the surfaces of the two clamps 1 5, so that the elbow-shaped cable head 4 can be locked.

[0035] When disassembling multiple elbow-type cable heads 4, they can be quickly positioned by the reverse movement of the two locking assemblies, and the position can be adjusted by the lateral movement of the two locking assemblies, thereby improving maintenance efficiency.

[0036] Working principle: When using the present invention, when disassembling the elbow-type cable head 4, the bidirectional screw rod 11 can be driven to rotate by the operation of the motor 2 10, so that the two sliders 2 12 connected to the external thread of the bidirectional screw rod 11 move in opposite directions, so that the two locking components can be automatically positioned at the two ends of the elbow-type cable head 4 and provide clamping force, and then the staff can connect the two bolts to lock it, which can be quickly positioned and fixed. When installing multiple elbow-type cable heads 4 in the same row, the one-way screw rod 8 can be driven to rotate by the operation of the motor 1 7, so that the slider 1 9 can drive the two locking components to move laterally, and perform laterally adjustment according to the position of other elbow-type cable heads, and then perform positioning by the reverse movement of the two locking components. There is no need for personnel to frequently position and fix, which improves maintenance efficiency.
