Description

Technical Field

[0001] The utility model relates to the technical field of escalators, in particular to a step chain used for super-high escalators. Background Art

[0002] An escalator is a convenient means of vertical transportation, usually used to connect buildings or large shopping malls on different floors. It can quickly and conveniently connect different floors in a building, allowing people to easily carry out vertical transportation, saving time and energy. In busy shopping malls, stations and other places, escalators can help people move faster, reduce congestion and improve passenger flow efficiency.

[0003] The step chain of the escalator in the prior art is fixed by a chain and a step shaft, and the step chain will generate friction during operation. In order to extend the service life of the step chain, the step chain needs to be lubricated. The existing chain lubrication method is to apply lubricating oil on the surface for lubrication, but this method has a poor lubrication effect and cannot fully lubricate the shaft pin at the chain connection.

[0005] Through the above technical solution, lubricating oil can enter the oil storage tanks on both sides through the oil filling hole, reducing the friction between the axle pin and the first sleeve, so that the chain can be more fully lubricated and have a better lubrication effect, thereby extending the service life of the chain. The first chain is used as the main chain for transmission support, and the second chain is used as an auxiliary chain for running guide. Therefore, the chain plates of the first chain use larger chain plates, and the chain plates of the second chain use smaller chain plates.

[0006] The utility model is further configured that a second sleeve is arranged on the outer side of the shaft pin near the inner chain, a bearing is arranged on the outer side of the second sleeve, and a flexible roller is installed on the bearing.

[0007] The utility model is further configured that an oil injection nozzle is arranged in the circulation hole, and the oil injection nozzle is communicated with the circulation hole.

[0008] Through the above technical solution, the oiling nozzle can easily inject lubricating oil into the circulation hole, and the oiling nozzle will not cause the lubricating oil to overflow, thereby reducing the waste of lubricating oil and avoiding the problem of inconvenience in cleaning caused by the overflow of lubricating oil.

[0009] The utility model is further configured that both ends of the shaft pin are provided with retaining rings, the retaining ring close to the outer chain is arranged on the side of the outer chain away from the inner chain, and the retaining ring close to the inner chain is arranged on the side of the inner chain away from the outer chain.

[0010] Through the above technical solution, the retaining ring is used to position and fix the chain to prevent the chain from falling off.

[0011] The utility model is further configured that one end of the shaft pin away from the oiling nozzle is rotatably connected to a step shaft, and the step shaft is a hollow structure.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model provides an oil storage tank and a circulation hole, and injects lubricating oil into the oil filling nozzle so that the lubricating oil is transmitted to the oil storage tank through the circulation hole. The oil filling nozzle will not cause the lubricating oil to overflow, thereby reducing the waste of the lubricating oil and also avoiding the problem of inconvenience in cleaning caused by the overflow of the lubricating oil. The lubricating oil stored in the oil storage tank can reduce the friction between the axle pin and the first axle sleeve, so that the chain can be more fully lubricated, with better lubrication effect, and extending the service life of the chain.
