Abstract
The present invention discloses a maintenance ladder in butt joint with the fixed ladder of a transmission tower pole. The maintenance ladder comprises a ground ladder and plate-type hooks. The top end of the ground ladder is provided with a circular pipe. The circular pipe is at least provided with two plate-type hooks and is hung onto the cross bar of the fixed ladder of the transmission tower pole. The upright column of the cross bar of the fixed ladder of the transmission tower pole is clamped between two plate-type hooks at the middle part of the circular pipe by the hooks. According to the technical scheme of the invention, the upright column of the cross bar of the fixed ladder of the transmission tower pole is clamped between the two plate-type hooks by the hooks, and the upright pipe of the ground ladder is sleeved by a sleeve on a hoop. Therefore, the maintenance ladder can be reliably connected with the fixed ladder of the transmission tower pole. Even in extremely windy days, the maintenance ladder is effectively prevented from shaking. Meanwhile, maintenance equipment can be conveyed to the upper part of the transmission tower pole through a hanging pulley and a pulley block. The maintenance ladder is convenient in maintenance and construction, labor-saving and time-saving. The maintenance ladder ensures the maintenance safety, and improves the labor efficiency.
