Description

Produce the device of composite sleeper

Technical field

The utility model relates to composite sleeper manufacturing technology fields, and in particular, to produce the device of composite sleeper.

Background technique

With the fast development of railway track traffic, the type of railroad sleeper is more and more, but has deficiency.

Reinforced concrete sleeper is than great, so that the heavy workloads such as installation, disassembly, transport, and its there are also intensity high, hardness Greatly, the feature that impact is big, noise is big, so replacing concrete sleeper with other sleepers in some regions at present.

Sleeper is most common sleeper, and elasticity is good, processability is strong, price is low, electrical insulating property is excellent, so be used for all the time On railway, but sleeper corrosion resistance is low, weatherability is poor, mechanical damage height, erosion of easily damaging by worms, timber resources are deficient and sleeper Only 5~15 years service life, service life are low after preservative treatment.

Composite sleeper has the spies such as density is low, intensity is high, resistance to decadent nature, weatherability, electric insulation impedance height, easy processing Point.It is applied at present in China, is mainly used in the regions such as subway railroad switch, bridge.

For the above three classes sleeper, large-scale timber, which can be used, in sleeper can be processed into various specifications size, and there is no viscous The problem of being connected into type；Concrete sleeper is molded by different molds and is made, so that bonding problem is also not present in required sleeper；Synthesize rail At present, there is the phenomenon that bonding in the composite sleeper of Chinese market composite sleeper and Japan's production with pillow.

This bonding composite sleeper is mainly influenced by external factor such as artificial, environment, when quality control is not tight, is being transported In defeated, carrying, installation and application process, it may appear that the case where bonding plane cracks, in railway operation, there are biggish hidden danger.

In addition, less appearance 140~160mm thickness is not bonded composite sleeper currently on the market, and do not occur with a thickness of 160~300mm's is not bonded composite sleeper, and reason has following two aspect: 1) heat release is not easily-controllable in composite sleeper production process System, 2) glue yarn dipping is mostly also in the rubbing stage by hand, or automation impregnation technology is unreasonable, realization rate is undesirable.
