Trapezoidal frame for line fault detection of illuminating lamp

Abstract

The invention relates to a trapezoidal frame, in particular to a trapezoidal frame for line fault detection of an illuminating lamp. The trapezoidal frame for line fault detection of the illuminating lamp is provided, wherein the trapezoidal frame can prevent a ladder from shaking and can store a detection tool. The trapezoidal frame for line fault detection of the illuminating lamp comprises a mounting frame, at least two pedals, a first cross rod, a bracket, two rubber pads and two connecting plates. The number of the pedals is at least two, and the pedals are installed on the mounting frame in a stepped manner. The first cross rod is mounted at the upper part of the mounting frame; the bracket is rotationally mounted on the first cross rod; the two rubber pads are mounted at the bottom of the bracket and the bottom of the mounting frame; and the two connecting plates are rotationally mounted at the two sides of the upper part of the bracket. When a line needs to be detected, a worker moves upwards through the pedals to conveniently detect the line, after detection is completed, the worker pushes the mounting frame to rotate rightwards to be folded, the worker can conveniently move, and when the mounting frame is unfolded, a limiting block can clamp a sliding shaft, so that the mounting frame is fixed, and abnormal rotation of the mounting frame in use is avoided.

Description

technical field [0001] The invention relates to a ladder frame, in particular to a ladder frame for detecting circuit faults of illuminating lamps. Background technique [0002] After long-term use of lighting lamps, line faults may occur, requiring staff to overhaul. Since the installation position of lighting lamps is generally relatively high, when performing maintenance on the lines, staff need to use ladders to move to a suitable height for maintenance. Commonly used Ladders are generally herringbone ladders. When in use, the staff will open the ladder frames on both sides and support them through the ladder frames on both sides, so that the staff can climb to a suitable height. The ladder frame on the side cannot be fixed, causing the ladder to shake easily, and the staff cannot borrow force when they are above the ladder, which is not convenient for maintaining their own balance, and the ladder cannot store the tools used for testing. [0003] Therefore, it is necess...
