The main components are equipment casing, bolts, front joints, insulating plugs and rear end covers. Usually, when installing new cable T-elbows, it is necessary to apply lubricants such as silicone grease on the surface of the equipment insulating casing in the cable room, and manually squeeze the front joint onto the equipment insulating casing.

[0003] For example, Chinese patent CN210326759U discloses a 0kV cable T-head disassembly device, including a base, a plurality of support rods, a screw rod, an adjustment device and a drive device, wherein the support rods are connected to the base; the screw rod can rotate through the base and is located between the support rods, and the output end of the drive device is connected to the screw rod; a hook can be movably hinged at the end of the support rod, and a plurality of first teeth are provided at one end of the hook at the hinge; the adjustment device is arranged on the support rod, and the adjustment device is provided with a plurality of second teeth, and the second teeth are transmitted by meshing with the first teeth, so that the adjustment device can adjust the tightening or opening of the hook.

[0004] Due to the small space in the cable room and the dense electrical components inside, the positions of several support rods in the device are relatively fixed, and the position of the hook cannot be adaptively adjusted according to the gap around the cable T-shaped elbow. In actual use, there are problems such as difficult operation and low practicality, which is not conducive to the rapid disassembly of the cable T-shaped elbow.

[0005] Therefore, we propose a cable T-elbow quick-disassembly device to solve the above problems. Summary of the invention

[0017] In the figure: 1 semicircular plate, 2 arc groove, 3 lead screw, 4 rotating rod, 5 hook arm, 61 connecting block, 62 side notch, 63 main notch, 71 slider, 72 screw, 73 positioning nut, 8 handle, 91 stud, 92 fastening nut, 10 multi-sided groove. DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] See also Figure 1-3 The present invention provides a technical solution for a quick-disassembly device for a cable T-shaped elbow: Embodiment 1: according to Figure 1-3 As shown, it includes a semicircular plate 1, a lead screw 3, N fixing parts and N sliding parts. An arc groove 2 is opened on the semicircular plate 1, and a threaded hole is opened at the center of the semicircular plate 1. A handle 8 is welded on the bottom of the semicircular plate 1, so that the user can hold the handle 8 and operate the device.

[0020] The front end of the lead screw 3 is an arc end, and a rotating rod 4 is provided at the rear end thereof. The lead screw 3 is threadedly connected to the threaded hole.

[0021] The sliding component includes a connecting block 61 and a slider 71. The interior of the connecting block 61 is hollow, and a main notch 63 is provided on one side arm away from the semicircular plate 1. The slider 71 is arranged in the inner cavity of the connecting block 61, and a screw 72 is welded on its side. The outer end of the screw 72 passes through the side notch 62 provided on the other side wall of the connecting block 61 and is threadedly connected with a positioning nut 73. By tightening the positioning nut 73, the positions of the screw 72 and the slider 71 are fixed, so that the slider 71 no longer slides.

[0022] The fixed end of the hook arm 5 passes through the main slot 63 and is fixedly connected to the slider 71, so that the hook arm 5 can adjust its own position as the slider 71 slides, so as to realize the rapid disassembly of the cable T-elbow with different port outer diameters, thereby improving the applicability of the device. The end of the hook arm 5 away from the connecting block 61 is a hook portion, and the hook portion of the hook arm 5 is brought into contact with the port of the cable T-elbow to facilitate the rapid disassembly of the cable T-elbow.

[0023] The fixing member is a stud 91, one end of which is fixedly connected to the connecting block 61, and the other end thereof extends out of the arc groove 2 and is threadedly connected with a fastening nut 92. By rotating the fastening nut 92 in the forward direction, the connecting block 61 is fixed after sliding to a predetermined position.

[0024] When used specifically, the cable T-shaped elbow quick disassembly device of the present invention first reversely rotates the positioning nuts 73 one by one, and adjusts the positions of the slider 71 and the hook arm 5 one by one according to the outer diameter of the port of the cable T-shaped elbow. After the hook arm 5 is adjusted to a suitable position, the positioning nuts 73 are tightened to fix the positions of the slider 71 and the hook arm 5. Then, the fastening nuts 92 are rotated in reverse one by one, and the positions of the connecting block 61 and the hook arm 5 are adjusted one by one according to the gap around the cable T-shaped elbow. After the hook arm 5 is adjusted to a suitable position, the fastening nuts 92 are tightened to fix the positions of the connecting block 61 and the hook arm 5. Finally, multiple hook arms 5 pass through the gap and contact the port of the cable T-elbow. At the same time, the arc end of the screw 3 presses on the insulating sleeve of the equipment. By rotating the screw 3, the three hook arms 5 drive the cable T-elbow to slide out slowly until the cable T-elbow is completely separated from the insulating sleeve of the equipment.

[0025] Embodiment 2: On the basis of the first embodiment, Figure 2 As shown, a multi-ribbed groove 10 is provided at the rear end of the lead screw 3 .

[0026] It also includes a hand drill, in which a polygonal shaft is clamped in the drill chuck of the hand drill, and the polygonal shaft matches the polygonal groove 10. By inserting the polygonal shaft into the polygonal groove 10 and operating the hand drill, the lead screw 3 is driven to rotate.
