Abstract

The invention discloses a herringbone ladder. The herringbone ladder comprises a front ladder, a rear ladder, a top plate, a tool box fixing clamp, two leaning frames, P nonskid chains and two non-slipping blocks, wherein the front ladder and the rear ladder are connected at two sides of the top plate respectively, each of the front ladder and the rear ladder is provided with N cross bars, the rod bodies of the front ladder and the rear ladder have M locating holes respectively, and two ends of the cross bar penetrate through the locating holes to be fixed on the rod body; the tool box fixing clamp is connected with the top plate; the two leaning frames are connected with the rod bodies of the front ladder and the rear ladder respectively; the P nonskid chains are connected between the front ladder and the rear ladder; and the two non-slipping blocks are fixed at the bottoms of the front ladder and the rear ladder respectively. The herringbone ladder has the technical effects of reasonable structure design, convenience in use, simplicity in operation, high safety, wide using range, and small possibility of causing fatigue to workers.

Description

technical field [0001] The invention relates to the field of construction equipment research, in particular to a herringbone ladder. Background technique [0002] The herringbone ladder is a kind of climbing tool used for decoration in the space above the plane (such as the roof). It is often used when decorating houses and is a common tool for construction workers. [0003] In the prior art, the tops of the existing ladders are connected together with loose leaves, which is convenient for short-term use. When it is necessary to work on the ladders for a long time, it is easy to get tired when standing for a long time, and the existing The crossbar of the ladder ladder is fixed. When there is no suitable crossbar to stand on the roof or the height of the object to be operated, the staff needs to stand awkwardly on the previous or next crossbar, which makes the operation inconvenient. And the existing technology The miter ladder has only one connecting chain of two ladders, ...
