Abstract

The invention provides a border hook ladder. The border hook ladder comprises a safety frame and a bent hook, wherein the safety frame consists of an oblique frame and a horizontal frame which are connected into a whole; guard bars are arranged in the horizontal frame, thereby constructing a working platform; a casing is connected to the oblique frame; the bent hook is sleeved in the casing; fence rods are connected between the oblique frame and the horizontal frame; an angle of 60-90 degrees is formed between the oblique frame and the horizontal frame; a reinforcing transverse rod is welded in the center of the oblique frame, and is welded together with the casing in an reinforced manner through angle iron; two fixing stop rods are welded in parallel at the joint of the horizontal frame and the oblique frame, and are equal in the lengths and the sizes; the guard bars are arranged transversely in the horizontal frame; small holes are formed in the casing at equal intervals; bolts are inserted into the holes. The border hook ladder is high in safety coefficient, low in manufacturing cost, convenient and easy to install, and suitable for welding and repairing inlet pipes.

Description

technical field [0001] The invention relates to pipeline and bridge construction ladders, in particular to a side hanging ladder. Background technique [0002] The installation, welding and maintenance of gas pipelines are often a relatively large project, especially for household pipelines. The installation, welding and maintenance of existing household pipelines are all carried out by hanging plates. The process is complicated and the cost is very high, especially for retail households. During construction, it consumes manpower and material resources, which is extremely uneconomical. [0003] The Chinese patent with the application number 201120464400.X discloses a utility model patent titled "An Adjustable Hanging Ladder", which includes an aluminum alloy hanging ladder. At least two hooks are arranged at the end of the aluminum alloy hanging ladder. No fence poles are set up, which may easily lead to safety accidents during the construction process.
