Abstract

The invention discloses a ladder with a sliding hoop. The ladder is characterized in that a guide rail, a fixed hoop and a sliding hoop are arranged at the upper end of the ladder, wherein the fixed hoop is fixedly connected with the right part of the guide rail; a slide block of the sliding hoop is slidingly matched with the left part of the guide rail; and one side of the ladder is provided with a sliding locking device which is connected with the sliding hoop. The fixed hoop and the sliding hoop are symmetrical clips which surround a pole; one end of the fixed hoop is fixedly connected with the right part of the guide rail through a piece of connection steel channel; and the slide block of the sliding hoop is a slide sleeve. The ladder with the sliding hoop, disclosed by the invention, is simple in structure and practical; the sliding hoop moves towards the pole to be matched with the fixed hoop; and the ladder and the pole are firmly fixed so that an operator can smoothly climb the pole for work, the number of constructors can be reduced, and human injuries are avoided.

Description

technical field [0001] The invention relates to a ladder, in particular to a ladder used for maintenance of electric poles. Background technique [0002] In electric power maintenance operations, operators are often required to climb poles over 18 meters in length. Due to the large diameter of the base of the pole and the small adjustment range of the catch arm, the operator cannot climb directly at the base of the pole, and needs to use a ladder to climb to the pole. At a height of 3 meters, you can use the foot buckle to climb upwards. Ordinary ladders need to lean on the poles, and the contact parts cannot form a stable contact surface. In addition, the maintenance site is complex. When constructing on the ground in the field, the base of the poles often has uneven terrain. It is very easy for the ladder to tip over, and the accident of falling and falling of the person climbing the pole occurs; if the operator on the pole is a little careless, the tool falls off, which ...
