Problems solved by technology

[0002] At present, the step chain is the main transmission part of the escalator. During the production process of the step chain chain, it is necessary to apply lubricating grease to the sleeve of the chain, and most manufacturers use manual brushing of lubricating grease during the production process of the chain. In this way, uneven coating inside the sleeve often occurs in this lubrication method, which leads to the failure of the assembled step chain to be well lubricated, and greater wear and tear during long-term use, which reduces the service life of the step chain and may eventually Causes the escalator chain to break during operation, which poses a great safety hazard

Abstract

The invention discloses a sleeve oiling device, which comprises grease metering valves, oiling nozzles, a solenoid valve and a pneumatic oiler. An external air source provides air for the solenoid valve, the pneumatic oiler and a pedal; an external oil storage device provides a lubricating grease for the pneumatic oiler; the lubricating grease output to the oiling nozzles from the pneumatic oileris adjusted through the grease metering valves; the solenoid valve controls the grease metering devices to open and close; each oiling nozzle comprises an oiling base and an oiling connector arrangedon each oiling base; each oiling base is provided with an oil inlet hole communicating with an oil outlet hole of each grease metering valve; each oiling connector is matched with an inner link sleeveof a trapezoid chain in a plugging way; and each oiling connector is provided with oiling holes communicating with the oil inlet hole and used for injecting the lubricating grease into an inner wallof each inner link sleeve. According to the device, the grease is evenly applied, the oiling amount is constant, and the service life of the trapezoid chain is prolonged.

Description

technical field [0001] The invention relates to the technical field of step chain auxiliary tooling, in particular to a sleeve oil injection device. Background technique [0002] At present, the step chain is the main transmission part of the escalator. During the production process of the step chain chain, it is necessary to apply lubricating grease to the sleeve of the chain, and most manufacturers use manual brushing of lubricating grease during the production process of the chain. In this way, uneven coating inside the sleeve often occurs in this lubrication method, which leads to the failure of the assembled step chain to be well lubricated, and greater wear and tear during long-term use, which reduces the service life of the step chain and may eventually This will cause the escalator chain to break during operation, which poses a great safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sleeve...
