Background
A tooth scraping chain for a railway line maintenance cleaning vehicle is a main component and a vulnerable component used in the railway line cleaning process. At present, the tooth pulling chain for railway line maintenance and cleaning vehicles in China generally adopts a low-cost base metal forged product of ZG45 (the base metal does not contain any wear-resistant and toughness-enhancing alloy elements). Its disadvantages are that it is not wear-resistant, it is easy to break, and its service life of the chain is generally within forty kilometers. Aiming at the current situations of short service life, high cost, low efficiency, high labor intensity of workers and the like of the raking tooth chain for the railway line maintenance cleaning vehicle in China. The utility model discloses from taking off the atress structure of tooth chain, wear-resisting material selection and the welding technique go up through the repeated screening practice, make its wearability of taking off the tooth chain and impact resistance's wholeness ability reach international advanced level, be domestic the initiative, be in internal leading position. Has good cost performance, and is a novel practical technology with extremely high energy-saving, environment-friendly and social benefits.
Disclosure of Invention
The utility model aims at the actual conditions of taking off chain tooth low in service life, intensity of labour is big, manufacturing cost is high for present railway circuit maintenance cleaning vehicle, what the scientific research personnel of my company had corresponding takes off two big problems of easy wearing and tearing, the big easy fracture of stress intensity of chain tooth existence and investigate and demonstrate. Technical innovation is carried out by selecting the wear-resistant material of the base material of the tooth-raking chain and optimizing the welding method, so that social end benefits of saving energy, reducing consumption, improving production efficiency and reducing use cost are achieved.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a chain is taken off to nanometer alloy for railway sieve cleaning vehicle, includes the support arm, and the connecting plate is taken off the chain connecting hole, is taken off tooth head, its characterized in that: the utility model discloses a take off tooth chain, including connecting plate, support arm, take off tooth head connecting hole, take off tooth chain connecting hole inside and be equipped with cylinder suit alloy, take off tooth chain connecting hole and cylinder suit alloy and link to each other through frequency brazing hot melt welding, take off the tooth overhead V type cap form that is equipped with the nanometer powder sintering carbide material sintering design that wearability and toughness are good and take off tooth head alloy component upper cover, it is stained with and bonds with wear-resisting nanometer alloy spare and takes off tooth head bonding an organic whole through high frequency brazing hot melt welding to take off the tooth head.
Preferably, the cylindrical sleeve alloy is made of powder sintered hard cylindrical sleeve-shaped alloy.
Preferably, the wear-resistant cylindrical nano powder sintered hard alloy is embedded in the connecting hole of the base metal chain of the scraper chain scraper.
The utility model has the advantages that the structure is simple, the use is convenient, the technology greatly enhances the wear resistance and the impact resistance of the raking tooth head, the whole rake tooth chain matrix chain body connecting hole and the pin are covered by the wear-resistant nano powder sintered hard alloy material through the soldering hot-melting welding adhesion, the wear resistance and the service life of the rake tooth chain are enhanced, the technology is domestic original technology, and the technology greatly enhances the wear resistance and the impact resistance of the rake tooth chain. Compared with the common steel head raking tooth chain adopted by the current domestic railway cleaning and screening vehicle, the service life of the raking tooth chain is 5 times that of the common raking tooth chain. The novel energy-saving environment-friendly product has the advantages that the use cost is reduced, the labor intensity of workers is reduced, and the novel energy-saving environment-friendly energy-saving environment.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-2, a nano alloy scraper chain for a railway cleaning vehicle comprises a support arm 1, a connecting plate 2, a scraper chain connecting hole 4, a scraper head 3, and is characterized in that: the upper end of the connecting plate 2 is provided with a supporting arm 1, the upper end of the supporting arm 1 is provided with a plurality of raking toothed chain connecting holes 4, a cylindrical sleeve alloy 5 is arranged inside the raking toothed chain connecting holes 4, the raking toothed chain connecting holes 4 are connected with the cylindrical sleeve alloy 5 through frequency brazing hot melting welding, a V-shaped cap-shaped raking toothed head alloy component sleeve cover formed by sintering a nano powder sintered hard alloy material with good wear resistance and toughness is arranged on the raking toothed head 3, and the raking toothed head 3 is adhered with a wear-resistant nano alloy piece and adhered with the raking toothed head into a whole through the high frequency brazing hot melting welding.
Wear-resistant nano-powder sintered hard alloy sleeves are used in the easily damaged tooth-raking chain holes to protect the connecting part matrix of the tooth-raking chain, so that the service life of the tooth-raking chain is prolonged. Through a plurality of technical tests, the company adopts domestic original nano powder sintering hard alloy material with excellent wear resistance and toughness on the tooth-pulling chain base material, a sintered and shaped cylindrical sleeve-shaped alloy component covers a hole and a bolt of a tooth-pulling chain connecting part, and then innovative high-frequency brazing hot-melting welding adhesion treatment is adopted, so that the hole and the bolt of the tooth-pulling chain are respectively adhered into a whole by the wear-resistant nano alloy component. The whole tooth-raking chain is integrally covered by the wear-resistant nano powder sintered hard alloy material, so that the wear resistance and the shock resistance of the tooth-raking chain are enhanced, and the wear-resistant nano powder sintered hard alloy is used for protecting a tooth-raking head matrix on a head which is easy to be damaged, so that the service life of the tooth-raking head matrix is prolonged.
