Description

Technical Field

[0001] The utility model belongs to the technical field of cable heads, and in particular relates to a device for disassembling a cable head of an electrical switch cabinet. Background Art

[0002] At present, electrical switch cabinets generally use pluggable cable T-type heads, the main components of which are equipment casing, bolts, front connectors, insulating plugs and rear end covers. Usually, when installing a new cable T-type head, it is necessary to apply silicone grease or other lubricants on the surface of the equipment insulating casing in the cable room, and manually squeeze the front connector onto the equipment insulating casing. It has good sealing and stress distribution. When repairing the electrical switch cabinet, it is necessary to unplug the cable head in the cabinet. Since the plug is basically in a vacuum state and the silicone grease has dried due to long-term operation of the cable, the fit between the cable front connector and the equipment insulating casing is very tight. In addition, the space in the cable room is small, and it is almost impossible to pull out the cable head by hand, which greatly affects the time for power distribution repairs. Utility Model Content

[0003] The purpose of the present invention is to provide a quick disassembly device for a cable head of an electrical switch cabinet.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Preferably, the positioning hole is arranged in a groove shape along the length direction of the frame of the fixing frame, that is, a positioning groove, which is used to adjust the position of the fixing frame on the door frame of the electrical switch cabinet.

[0007] Preferably, a hand-pull positioning hole is provided on the top surface of the support frame on the side opposite to the fixing frame.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. The utility model designs a quick disassembly device for the cable head of an electrical switch cabinet. It uses a hand chain hoist as a power source. When disassembling the cable head, first fix the disassembly device to the electrical switch cabinet, then connect one end of the hand chain hoist to the hand-pull positioning hole to obtain support, and wrap the other end of the pull rope around and fix it on the cable head. The cable head is quickly disassembled using a large pulling force through the hand chain hoist. The quick disassembly device can greatly shorten the cable head disassembly time and improve work efficiency.

[0010] 2. The electrical switch cabinet cable head quick disassembly device designed by the utility model is provided with symmetrically arranged positioning grooves on the bottom surfaces of the two opposite sides of the fixed frame, and the positioning height of the disassembly device can be adjusted to cope with the disassembly scenarios of cable heads at different heights.

[0011] 3. The electrical switch cabinet cable head quick disassembly device designed in the utility model also includes an opening and closing component. By adjusting the angle between the support frame and the fixed frame, the force direction of the cable head and the setting direction of the cable head are located in the same plane to achieve the best force effect.

[0012] 4. The electrical switch cabinet cable head quick disassembly device designed by the utility model has a simple structure and is easy to manufacture. It can be folded and stored by removing the fixing screws, which reduces space occupation and is convenient for work and carrying. BRIEF DESCRIPTION OF THE DRAWINGS
