Problems solved by technology

[0003] However, the strength of wood is too low. When the height of the ladder reaches a certain value, it cannot withstand excessive pressure. The strength of steel is high, but the proportion of the material is relatively large. Difficult, the strength of the aluminum alloy material is also poor, and the height of the ladder cannot be made too high
[0004] Limited by the strength and specific gravity of the material itself, the height of the ladder made of the above materials is greatly restricted. At present, the height of the ladder in my country is generally about 50 meters, and the highest ladder in China can only reach a height of 70 meters.
[0005] With the continuous advancement of urbanization, high-rise buildings are getting higher and higher, and the height of the aerial ladder is too short. The problems caused by emergency rescue work such as marine accidents, mountaineering rescues, and air rescues have become increasingly prominent, affecting rescue time and rescue effects.

Embodiment 1

[0019] The invention provides a method for manufacturing a ladder made of composite materials, which includes the following steps: putting high-strength carbon fibers into a mold after braiding and surface treatment; putting titanium alloy or magnesium alloy or engineering plastic at a temperature of about 430-750 degrees Melt, pour the melted titanium alloy or magnesium alloy or engineering plastic into the mold; make the frame and boarding layer of the ladder.

[0020] The frame and boarding layer of the ladder are directly solidified and formed as a whole.

[0021] The frame of the ladder and the boarding are bonded together or fixedly connected by screws.

Embodiment 2

[0023] Melt titanium alloy or magnesium alloy or engineering plastic at a temperature of about 430-750 degrees, melt the titanium alloy or magnesium alloy, weave high-strength carbon fiber into cloth by warp and weft weaving, and then pre-soak it in the melted melt, and then carry out The frame and boarding layer of the ladder are made of high-temperature curing molding.

[0024] The aerial ladder of the present invention can be made into small sections connected one by one, and the sliding part of the aerial ladder can be made of graphite material with good self-lubricity, which can be positioned and slid with each other, waterproof and dustproof.

Abstract

The invention relates to a manufacturing method for a composite material scaling ladder. The manufacturing method comprises the following steps: melting a titanium alloy or magnesium alloy or engineering plastic at the temperature of about 430-750 DEG C; performing preparation forming and surface treatment on high-strength carbon fibers and then placing the treated high-strength carbon fibers in a mold; pouring the melt titanium alloy or the magnesium alloy or the engineering plastic in the mold or knitting the high-strength carbon fibers into cloth by adopting a warp / weft knitting method and then immersing the cloth in the melt liquid in advance for film pressing and forming. The scaling ladder disclosed by the invention has the advantages of being high in strength, light in weight, high in attitude, easily-obtained in material source, and worthy of wide popularization.

Description

technical field [0001] The invention relates to the field of research and development of fire-fighting equipment, in particular to a method for manufacturing a ladder made of composite materials. Background technique [0002] Aerial ladders are widely used in fields such as fire protection, high-altitude operations, street lamp maintenance, construction installation, maintenance, mountain climbing, field observation, rescue, and high-altitude rescue. At present, the materials for making aerial ladders are mainly divided into three types: one is wood, and the other is wood. The first is to use steel, and the third is to use aluminum alloy materials. [0003] However, the strength of wood is too low. When the height of the ladder reaches a certain value, it cannot withstand excessive pressure. The strength of steel is high, but the proportion of the material is relatively large. Difficult, the strength of the aluminum alloy material is also poor, and the height of the ladder ...
