The invention relates to a cable puncture tool, in particular to a high voltage cable puncture device. At least two slot openings (13) are formed on the two side plate walls of a U-shaped sheet (12) respectively and face each other; through-holes (16) are arranged on the two side surfaces of a square clamping block (10) and communicated with each other, and correspond to the slot openings; a fixing bolt (15) passes through the first slot opening, the through-holes and the second slot opening and then is connected with a nut A (11); a locking bolt (7) passes through a fixation hole B (18) and a fixation hole A (9) and then is connected with a nut B (14); the upper end of a twist drill is connected with the lower end of a threaded rod (1); one side of a rotating arm is fixedly connected at the upper end of the threaded rod; the twist drill is inserted into a guide hole (17); and a handle is arranged on any one side of a goal-shaped frame (6) and used for ensuring the stability during the screwing and twisting process. The exposed parts of the components are all coated with insulating paint. The invention can prevent the serious security incident of personal injury caused by the wrong puncture operation or sawing operation of the high voltage cable.
Description
【Technical field】 [0001] The invention relates to a cable puncture tool, in particular to an anti-electric shock high-voltage cable puncture device. 【Background technique】 [0002] At present, for the overview, the cable operation and maintenance departments have been testing cables in accordance with the requirements of Article 234 of the People's Republic of China Industry Standard DL409-91 "Safety Work Regulations for the Electric Industry (Power Lines)". Transmission lines, in the process of large-scale construction and renovation, involve the transformation and re-laying of many live cables. One of the main tasks is to cut the cables. In the process of cable cutting, the first thing to do is to check whether the cables are live or not. , After determining the cable to be tested, one person first puts on insulating gloves, holds the grounded iron rod and aligns the cable, and then the other person uses a hammer to drive the iron rod into the cable to be cut until the iro...
