Line maintenance bearing support capable of stable positioning

Abstract

The invention discloses a line maintenance bearing support capable of stable positioning. The bearing support includes an insulating bar working head, an electricity testing head and a telescopic piece. The telescopic piece includes a bottom part cannula, an extension pipe and a positioning lever. A lower end of the extension pipe is connected to a first positioning screw thread head. The first positioning screw thread head is connected to an upper end of the bottom part cannula through screw thread matching. A lower end of the positioning lever is connected to a second positioning screw thread head. The second positioning screw thread head is connected to an upper end of the extension pipe through screw thread matching. A top end of the positioning lever recesses inwardly to constitute apositioning screw hole. The lower ends of the insulating working head and the electricity testing head are both connected to a positioning screw. The bottom part cannula is sleeved thereon with an anti-skid sleeve which is in interference fit with the bottom part cannula. According to the invention, a line maintenance bearing support can ensure extension length through the telescopic piece, and conducts electricity testing and back brake on the ground, so that the line maintenance bearing support is easy to operate and can prevent safety hazards caused by operating workers performing work by climbing the support.

Description

technical field [0001] The invention relates to an auxiliary tool for electric power construction, in particular to a support frame for line maintenance with stable positioning. Background technique [0002] With the development of industry, all walks of life have increasing requirements for the reliability and stability of power supply of power systems, so it is particularly important for the operation, maintenance and repair of power systems. When operating the switch in the power system, sometimes the indicator will go to the sub-position after the switch operating lever is moved, but the internal mechanism has problems and is not actually separated, resulting in the situation of pulling the switch with load, which has a large risk Potential safety hazards. Therefore, after the switch is turned off, the staff usually performs the switching after the load side is checked. The existing general-purpose electroscope pen is relatively short in length, and the switch operator ...

Problems solved by technology

When operating the switch in the power system, sometimes the indicator will go to the sub-position after the switch operating lever is moved, but the internal mechanism has problems and is not actually separated, resulting in the situation of pulling the switch with load, which has a large risk Potential safety hazards, therefore, after the switch is disconnected, the staff usually perform the switching operation after the load side power test

The existing general-purpose electroscope pen is relatively short in length, and the switch operator must climb the pole to the switch to conduct an electrical inspection when inspecting the load side. The stick is passed to the operator on the pole for switching operation, the operation efficiency is low, and there is a safety hazard for the switch operator to operate on the pole
