Angle iron tower climbing device

Abstract

The invention discloses an angle iron tower climbing device. The angle iron tower climbing device comprises connecting plates and U-shaped foot pins; the upper end and the lower end of each connecting plate are penetrated by long screw pitch ends of two corresponding U-shaped foot pins, and the long screw pitch ends of the U-shaped foot pins are fixedly connected with an angle iron of an angle iron tower; short screw pitch ends of the U-shaped foot pins are fixedly connected with the connecting plates; the U-shaped foot pins are vertically arranged on the two sides of the angle iron in two lines in a left-right alternative manner along the direction of the angle iron; and the plurality of connecting plates are arranged in an alternative manner. According to the angle iron tower climbing device, the U-shaped foot pins and the limit connecting plates are arranged on a steel support conveniently and rapidly using original foot pin holes of single-rib foot pins left on the steel support, assembling and disassembling and maintenance are convenient, impact of operating personnel with end parts of single-rib foot pins after falling is avoided, operating dangerousness is reduced, accident seriousness is reduced, double end fixed connection is adopted, foot pin connection is reliable, climbing is more safe, hanging of safety belts is more convenient, and it is convenient to find slits via cleaning for hanging of safety belts even in winter when iron towers are covered with ice.

Description

technical field [0001] The invention relates to a climbing device for an angle steel tower, which belongs to the technical field of electric power maintenance climbing equipment. Background technique [0002] One end of the single tendon foot nails used on the existing angle steel towers is fixedly connected to the steel pipe or the angle steel tower through nuts, and they are arranged in a staggered manner. Serious injury, and the nut may be loose due to the long-term erosion of the sun and rain under stress, and the climbing safety is poor; in addition, a safety belt is installed on the lower side of the outer end of the existing single tendon foot nail The hook frame will be frozen and closed in case of ice and snow disasters. If a large square frame is used, when the foot nails are held by hand during climbing, the torque will become larger and the foot nails will rotate. Part of the seat belt hook frame is welded, and the anti-corrosion and anti-shedding of the welding...

[0002] One end of the single tendon foot nails used on the existing angle steel tower is fixedly connected to the steel pipe or the angle steel tower through a nut, and they are arranged in a staggered manner. Serious injury, and the nut may be loose due to the long-term erosion of the sun and rain under stress, and the climbing safety is poor; in addition, a safety belt is installed on the lower side of the outer end of the existing single tendon foot nail The hook frame will be frozen and closed in case of ice and snow disasters. If a large square frame is used, when the foot nails are held by hand during the climbing process, the torque will become larger and the foot nails will rotate.
