Abstract

A pull-type safe ladder for a high-voltage wire frame (1), comprising tread baffles (7), ladder cross rods (9), a baffle slide hole (10), tread cavities (11), a clamping block (25), a clamping block slide hole (26) and a control rod (27), wherein a ladder knob (5) controls up and down movement of the control rod (27), thereby controlling the clamping block (25) to slide between the clamping block slide hole (26) and a vertical hole so as to unlock or lock all of the tread cavities (11) and tread baffles (7).

Description

Technical field [0001] The invention belongs to the technical field of climbing ladders for high-voltage wire racks, and in particular relates to a pull-type safety ladder for high-voltage wire racks. Background technique [0002] At present, the high-voltage wire frame is very high. When the high-voltage wire frame needs to be repaired or inspected by maintenance personnel, the maintenance personnel climbs to the top through the ladder on the high-voltage wire frame for maintenance or inspection. Therefore, for high-voltage wire racks, climbing ladders are a must, which cannot avoid serious high-voltage accidents caused by non-professionals climbing the ladders. How to design the ladder, which can not only make it convenient for professionals to go up and down, but also prevent non-professionals from going up and down, is of great design significance. [0003] The present invention designs a pull-type high-voltage wire frame safety climbing ladder to solve the above proble...
