Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator guide rail lubrication device. Background Art

[0002] As one of the main supporting structures during the elevator lifting process, the elevator guide rail is usually reciprocated with the existing elevator guide shoe to ensure the stability of the elevator lifting. In order to avoid the phenomenon of increased friction caused by the elevator guide rail and the elevator guide shoe being fitted for a long time, a synchronous lubrication device will be set on the elevator, and the detailed technical content of the lubrication device has been disclosed. For example, the patent document with application number CN201921087884.3 discloses an elevator guide rail lubrication device that "the elevator guide rail lubrication device is provided with a motor. When lubricating oil needs to be added to the slide groove, the motor is started to drive the rotating shaft to rotate. The rotation of the rotating shaft drives the threaded sleeve to rotate under the cooperation of the first bevel gear and the second bevel gear. The rotation of the threaded sleeve drives the threaded rod and the baffle to move to the left under the cooperation of the limit slide rail and the limit slider, thereby moving the baffle away from the oil outlet and starting to leak oil into the slide groove. While the rotating shaft rotates, the driving wheel and the connecting belt are used to drive the rotating rod to rotate. The rotation of the rotating rod drives a group of disturbance leaves to rotate. The oil leaking into the slide groove is dispersed by the disturbance leaves, so that the inner surface of the slide groove is evenly lubricated."

[0003] However, in addition to the concave guide structure, the elevator guide rails currently in use are more often protruding T-shaped structures. Judging from the technical content disclosed in the above-mentioned prior art, its technical structure may interfere with the T-shaped elevator guide rails during operation, which has limitations in use. Secondly, the extended lubrication of the rotary striking type lacks precise control over the direction and range of the lubricating oil operation, and some of the lubricating oil will be used ineffectively.

[0032] Working principle:

[0033] Example 1

[0034] The entire device is installed at the bottom of an existing elevator guide shoe and moves synchronously with the elevator. During the elevator's ascent and descent, the elevator guide shoe and the elevator guide rail are fitted together to guide and support the elevator. At the same time, the solenoid valves in the two solenoid valve tubes 7 are opened by the control component 9, and the lubricating oil in the lubricating oil tank 3 is transported through the two solenoid valve tubes 7 to the inside of the two transition infusion components 5. The lubricating oil is then diverted through the two transition infusion components 5 to the inside of the two spray pipes 8.

[0035] While the entire device moves synchronously with the elevator, the two transmission wheel shafts 4 rotate in contact with the surfaces on both sides of the elevator slide rail 1, and then the two pressure blocks 6 periodically press their corresponding transition infusion components 5. After the two transition infusion components 5 are compressed and contracted, the lubricating oil inside them will be pressurized synchronously and finally sprayed onto the surface of the elevator slide rail 1 through the multiple atomizing nozzles 83 inside the corresponding spray pipe 8, realizing automated lubrication processing and ensuring the stability of the mutual fitting of the elevator guide shoe and the elevator guide rail.

[0036] Example 2

[0037] For the lubrication treatment of the elevator slide rail 1, it is sufficient to operate according to the above-mentioned embodiment 1. When the active lubrication of the elevator slide rail 1 is completed, the solenoid valves inside the two solenoid valve tubes 7 are closed, and a certain amount of lubricating oil will remain inside the two transition infusion components 5. At this time, the lubricating oil dripping from the atomizing nozzles 83 in the two spray pipes 8 can be collected separately by the two semi-open hollow sleeves 12 for secondary collection. Then, it is absorbed by the oil-absorbing cotton block 13 and covered and smeared on the surface of the elevator slide rail 1 again to avoid waste.
