Abstract

The invention discloses a special safe power-off device for electric power machine maintenance personnel. The special safe power-off device comprises a base, wherein two first supporting rods are rotationally installed on the top side of the base, second supporting rods are rotationally installed at the top ends of the two first supporting rods through rotating shafts, and the top ends of the twosecond supporting rods are fixedly provided with the same operating table; and a fixed rod and a sliding rod are movably installed on the sides, close to each other, of the two rotating shafts correspondingly, a sliding groove is formed in the end, far away from the corresponding rotating shaft, of the fixed rod, one end of the sliding rod is slidably installed in the sliding groove, a placing groove is formed in one side of the sliding rod, a rack is fixedly installed in the placing groove, and a gear positioned in the sliding groove is meshed with the rack. According to the special safe power-off device, the height position of the operating table can be stably and conveniently adjusted, the operation by maintenance personnel is facilitated, and safe power off can be conveniently carriedout through a sensor; and meanwhile, the sensor can be stably and conveniently assembled and disassembled, and the maintenance and replacement of the sensor are facilitated.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a special safety power-off device for electric machine maintenance personnel. Background technique [0002] The power industry generally uses ladders when performing maintenance work on high maintenance points. For safety reasons, it is best to need another person to support the ladder. Poor reliability. In addition, when multiple people are required to cooperate for maintenance, the space on the ladder is limited and multiple people cannot stand; in addition, the existing lifting makes the power maintenance device generally not equipped with guardrails, and the risk factor for maintenance personnel is too high; it is not conducive to power maintenance work development. [0003] The patent with the application number 201620226670.X discloses a lifting type power maintenance device with a guardrail, including a support base, a base, a lifting device and a guardrail; the ...
