Problems solved by technology

[0003] In addition, the production of FRP components by hand lay-up process is cumbersome, and the quality is unstable, which will bring certain safety hazards. At the same time, the shaft equipment produced by hand lay-up process has the disadvantage of not being reusable, which greatly wastes resources.

Abstract

The invention relates to a novel pultruded fiber reinforced plastic (FRP) ladder, which comprises a pultruded FRP side plate and a pultruded FRP footboard. A connecting rod is disposed inside the pultruded FRP footboard. The pultruded FRP side plate is fixedly connected with the pultruded FRP footboard through the connecting rod. The pultruded FRP ladder provided by the invention has advantages of simple structure, high safety factor and long service life.

Description

technical field [0001] The invention relates to a ladder, in particular to a glass fiber reinforced plastic ladder. Background technique [0002] In the usual mine production operation, in order to facilitate the operator to enter and exit the mine up and down, it is generally necessary to install a mine ladder room in the shaft, and enter and exit the mine through the ladder. At present, the general mine ladders are all made of ordinary steel, which is welded by steel plates, section steel, round steel and other steel materials. Due to the high humidity and rotten substances in the mine, the ladders made of steel are prone to rust and rot, especially the welded joints are prone to rust and fall off, which poses a safety hazard. For this, every few years It is necessary to replace the components and carry out anti-corrosion treatment. The protection is difficult, the construction quality is difficult to guarantee, and the maintenance cost is high. There is also a glass fib...
