An oblique wedge telescopic stainless steel mobile climbing ladder

Abstract

The invention relates to an oblique wedge telescopic type stainless steel mobile climbing ladder. According to the climbing ladder, frames comprise fixing sleeves, connecting plates and springs, wherein the four fixing sleeves are respectively and fixedly arranged at four corners of a ladder frame through the connecting plates; ejector rods are fixedly arranged on the upper parts of casters; the springs penetrate through the ejector rods; the inner side of the bottom of the ladder frame is provided with a slide block fixing rack; four corners of the slide block fixing rack are respectively provided with oblique wedge type slide blocks; the bottoms of the oblique wedge type slide blocks respectively serve as a lifting plane, a transition inclined plane and a downward pressing plane; two side walls of each fixing sleeve are respectively provided with a first chute in an oppositely-penetrating manner; the oblique wedge type slide blocks are movably arranged in the first chutes; the bottom of the rear side of the ladder frame is provided with a U-shaped pull rod; and the bottom ends of two side rods of the U-shaped pull rod are respectively arranged on the ladder frame in a hinging manner. The action of an oblique wedge telescopic mechanism is controlled through the pull rod, and the climbing ladder is easy and convenient to move, fix and operate.

Description

technical field [0001] The invention relates to a climbing ladder. Background technique [0002] According to the safety standardization requirements of the tobacco industry: when the height of the mobile climbing ladder (platform) from the reference plane is greater than or equal to 2m and less than 20 m, the height of the protective railing should not be less than 1050 mm. Combined with the actual production of our factory, the climbing ladder (platform) Generally not up to standard. Combined with the actual situation of the workshop site, it must be ensured that the climbing ladder can easily pass under the conveying line with limited height requirements in the workshop, that is, the overall height of the climbing ladder should not exceed 3500mm (including fixed protective railings), and it is generally necessary to ensure that the climbing ladder operation in the workshop is feasible The stair height of the climbing ladder must be 2800mm. In this way, to meet the requir...

Problems solved by technology

Combined with the actual situation of the workshop site, it must be ensured that the climbing ladder can easily pass under the conveying line with the limited height requirement of the workshop, that is, the overall height of the climbing ladder should not exceed 3500mm (including fixed protective railings), and it is generally necessary to ensure that the climbing ladder operation in the workshop is feasible The stair height of the climbing ladder must be 2800mm. In this way, if the requirement of adding a protective fence of 1050mm is added to meet the benchmarking requirements, the climbing ladder cannot pass through the conveyor line normally. Mobile climbing ladder (platform) for safety benchmarking requirements
