Safety insulation ladder for operation and maintenance management of substations

Abstract

The invention discloses a safety insulation ladder for operation and maintenance management of substations. The safety insulation ladder comprises an insulation ladder body, and a locking mechanism is arranged on the upper portion of the insulation ladder body and comprises a left hoop, a right hoop and a locking module. The locking module comprises a C-shaped supporting rod, a driving motor, a C-shaped locking rod, an electronic lock and a processor, one end of the C-shaped supporting rod is connected with the C-shaped locking rod through the driving motor, the electronic lock is arranged at the other end of the C-shaped supporting rod, the tail end of the C-shaped locking rod is provided with locking teeth matched with the electronic lock, and the driving motor and the electronic lock are both connected with the processor through wires. The safety insulation ladder has the advantages that remote control of the electronic lock and the driving motor can be realized by adopting a wireless remote key for controlling, and defects of direct on and off and line control are avoided; by the aid of the driving motor, control of the C-shaped locking rod can be realized, safety is greatly improved, and the safety insulation ladder is more convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of electric power basic equipment, and in particular relates to a safety insulating ladder for substation operation and maintenance management. technical background [0002] At present, in the electric power industry, insulated single ladders are often used for climbing operations on equipment such as 220kV voltage transformers, metal zinc oxide arresters, and current transformers; The upper end of the insulating ladder is directly placed above the cylindrical tower pole, but because it is mostly a flat pole or a rope, it is easy to tilt, the safety factor is low, and the life safety of electric workers cannot be well guaranteed; although the rope plays a certain role in preventing Tilt effect, but it does not fundamentally solve the problem. [0003] In CN 203377550 U, an insulating single ladder with a hoop device is disclosed, which includes an insulating single ladder body, and the upper end of the insu...

Problems solved by technology

[0002] At present, in the power industry, insulated single ladders are often used for climbing operations of 220kV voltage transformers, metal zinc oxide arresters, current transformers and other equipment; The upper end of the insulating ladder is directly placed above the cylindrical tower pole, but because it is mostly a flat pole or a rope, it is easy to incline, the safety factor is low, and the life safety of electric workers cannot be well guaranteed; although the rope plays a certain role in preventing Tilting effect, but it does not fundamentally solve the problem

[0003] In CN 203377550 U, an insulating single ladder with a hoop device is disclosed, including an insulating single ladder body, and the upper end of the insulating single ladder body is provided with a hoop device, and the hoop device includes a left hoop, a The body and the right hoop, the left hoop, the support body and the right hoop are integrally structured, and the left hoop and the right hoop are symmetrically arranged, and the left and right ends of the support body are symmetrically provided with single-ladder locking devices, so The locking device includes a steel sleeve, the steel sleeve is threaded with a locking bolt, the upper end of the vertical bar of the insulating single ladder body is inserted into the corresponding steel sleeve, and the corresponding insulating single ladder body is locked by the locking bolt However, it adopts the hoop type, although it plays a certain role in fixing, but its fixing is still unstable, difficult to remove, and difficult to assemble and unload. Therefore, a device that can overcome these points is needed
