Coated-type composite balance weight and manufacturing method thereof

Abstract

The invention discloses a coated-type composite balance weight and a manufacturing method thereof. The coated-type composite balance weight is made of main materials as industrial mineral waste residue (1) and an inorganic bonding agents (3), wherein the weight of the industrial mineral waste residue accounts for 70-85% of the total weight; the weight of the inorganic bonding agents accounts for 7-25% of the total weight; the coated-type composite balance weight further comprises a reinforcing material (2) which can be short fibers or particulate fibers, and accounts for 0.5-3% of the whole weight; a layer of shell (4) is coated on the outer layer of the coated-type composite balance weight, and materials for preparing the shell can be materials such as rubber and epoxy resin. The coated-type composite balance weight provided by the invention can be compressed and molded once through using a mold, is stable in weight after forming, is high in pressure resistant intensity, is extremely low in moisture absorption rate, is a compound material, can prevent the possibility of being stolen, is good in freezing resistance, is good in durability, has long service life, and can avoid problems of cracking, corner falling, block falling and the like after being used for a long time, so that the quality of the balance weight and the safety of a contact net system can be ensured.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a clad composite weight applied to a tension compensation mechanism of an electrified railway catenary and a manufacturing method thereof. Background technique [0002] Electrified railway is a modern railway in which electric locomotives are used as the traction power of trains. The catenary is responsible for the important task of directly transmitting the electric energy obtained from the traction substation to the electric locomotive, and is regarded as the artery of the electrified railway. Therefore, the quality and working status of the catenary will directly affect the transportation capacity of the electrified railway. [0003] The pendant is an anchor compensation device for the catenary system of the electrified railway, which plays the role of adjusting the tension compensation of the catenary cable or contact line. What are commonly used in China at present are co...

AI Technical Summary

Problems solved by technology

The iron pendant is small in size and stable in weight, so it is prone to theft and the collapse of the network will seriously affect the safety of the power supply of the catenary and the safety of train operation; the concrete pendant is large in size and has water absorption, and the weight of the pendant will change, causing the tension of the catenary wire to occur Changes, poor durability, etc.
