[0002] The automatic escalator is an electric transport tool for transporting passengers in the form of a conveyor belt. It drives the chain to drive the escalator to circulate and form a staircase surface through a motor, and is equipped with a handrail that moves synchronously. When riding, it is necessary to pay attention to the running direction, hold the handrail tightly, stand steadily and not play, avoid clothes or body parts from approaching dangerous areas such as comb plate and apron plate, and pay more attention when taking children. In case of emergency, the red emergency brake button can be pressed to stop running. It is widely used in places with high population density such as shopping malls and stations to provide convenient vertical traffic services for pedestrians.

[0003] Among them, when the escalator is running, a lubricating device needs to be used, which is mainly responsible for providing lubrication for key moving parts such as chains, bearings and gears to ensure smooth operation of the equipment. It is usually composed of oil storage components, conveying pipelines, distributors and control units. Through automatic or manual methods, lubricating oil is accurately delivered to each lubrication point to reduce friction and wear between parts, reduce operating noise and prolong equipment life.

The oil injection mechanism sprays lubricating oil onto the surface of the chain. The application also includes an oil collecting assembly arranged below the oil injection mechanism and the chain to collect the lubricating oil dripping from the chain. The application has the effect of spraying lubricating oil onto the surface of the chain by the oil injection mechanism, collecting excess lubricating oil by the oil collecting assembly, and recycling the lubricating oil, thereby improving the cleanliness of the escalator environment.

[0005] However, the lubricating device in the prior art has significant drawbacks when in use. The oil injection mechanism sprays lubricating oil onto the surface of the chain. However, due to the viscosity of the lubricating oil, dust inside the escalator is easily adhered to the nozzle of the oil injection mechanism during long-term use, causing the nozzle to be blocked and seriously affecting the use effect of the lubricating device. On the other hand, the lengths of the oil conveying branch pipes differ, which makes it difficult to maintain the balance of the oil outlet pressure and flow rate at the ends of the oil conveying branch pipes when the electric lubricating pump delivers lubricating oil to oil conveying branch pipes of different lengths. This results in uneven lubrication effect at different parts of the chain, further affecting the normal operation and service life of the equipment.

A lubricating method for an escalator based on the lubricating device for an escalator according to any one of claims 1 to 9, characterized in that: The lubrication method comprises: S1: starting the conveying mechanism so that the conveying mechanism conveys the lubricating oil in the lubrication box (2) to the inside of the main frame (3), and the lubricating oil is conveyed to the plurality of stepping pipes (4) through the main frame (3) until the plurality of stepping pipes (4) are filled with the lubricating oil; S2: The driving end of the synchronous driving mechanism drives the plurality of grading pipes (4) to slide inside the main frame (3), so that the spraying ends of the plurality of grading pipes (4) are separated from the main frame (3), and the lubricating oil is discharged through the spraying ends of the plurality of grading pipes (4), and the lubricating oil is sprayed into the escalator body (1); S3: When the lubricating oil is discharged through the spraying ends of the plurality of grading pipes (4), the pressure compensation mechanism is driven synchronously, so that the elastic end of the pressure compensation mechanism presses out all the lubricating oil in the grading pipes (4); S4: the driving end of the synchronous driving mechanism drives the plurality of grading tubes (4) to slide inside the main frame (3), so that the spraying ends of the plurality of grading tubes (4) are retracted into the main frame (3), thereby shielding the spraying ends of the grading tubes (4); S5: The recovery mechanism collects the lubricating oil dripping from the escalator body (1), and re-transports the lubricating oil into the lubrication box (2) through the recovery end of the recovery mechanism.
