Description

Technical Field

[0001] The present invention relates to the technical field of elevator components, and particularly relates to an oil scraping device for elevator steel wire ropes to remove oil. Background Art

[0002] With the large-scale popularization of elevators, for users in some high-quality communities, such as adding air conditioners to the elevator machine room and painting the ground, the entire machine room environment is required to be clean and beautiful. The traction machine in the machine room starts and rotates frequently. After long-term use, the sludge inside the steel wire ropes hanging on the traction machine will be thrown out along with the traction wheel, making it difficult to clean the ground and walls.

[0003] For this reason, the Chinese invention patent authorization publication number CN205973357U discloses a steel wire rope cleaning and maintenance device, including an oil scraping device and a cleaning device. The oil scraping device includes a bracket, a bushing installed on the bracket, and an oil scraper that is in interference fit with the bushing through a bearing. At least one set of the oil scrapers is provided. The oil scraper is a cylindrical structure with a two-stage stepped outer wall. The middle part thereof is an oil scraping blade. The front end of the oil scraping blade is a guide sleeve, and the rear end is a storage cavity. The middle part of the oil scraping blade is an oil scraping hole. The cross-sectional shape of the oil scraping hole matches the cross-sectional shape of the steel wire rope to be cleaned. The guide sleeve forms a bearing with steel balls and the outer ring of the bearing as the inner ring of the bearing, and the outer ring of the bearing is in interference fit with the bushing; the oil scraper and the cleaning device are installed in a matching manner with the steel wire rope. The cross-sectional shape of the oil scraping hole in the middle of the oil scraper is the same as the cross-sectional shape of the steel wire rope. When the steel wire rope passes through the oil scraping hole, the excess grease on the surface of the steel wire rope can be scraped off and stored in the storage cavity. The cleaning device can clean the surface of the steel wire rope to ensure that there is no oil stain. However, the oil scraping device in the above patent cannot remove the sludge on the traction wheel of the traction machine, resulting in the sludge on the traction wheel of the traction machine being thrown out and polluting the machine room.

[0025] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0026] See Figures 1 to 4 , the oil scraping device for the oil leakage of the elevator steel wire rope shown in the figure includes a fixed bracket 10, a brush 20, two oil scraping pieces 30 and two oil collecting boxes; the two oil collecting boxes are divided into a first oil collecting box 40 and a second oil collecting box 50. Of course, the number of the oil scraping pieces 30 can also be one or more than two, which is set according to needs.

[0027] The fixing bracket 10 is L-shaped, and its vertical plate 11 is fixed to the frame 61 of the traction machine 60 by fasteners (see Figure 4 ). The bottom plate 41 of the first oil collecting box 40 is fixed to the horizontal plate 12 by fasteners, and one side plate 51 of the second oil collecting box 50 is fixed to the vertical plate 11 by fasteners. The second oil collecting box 50 is located below the first oil collecting box 40.

[0028] The oil collecting cavity of the first oil collecting box 40 is separated into a first oil collecting sub-cavity 43 and a second oil collecting sub-cavity 44 by a partition plate 42. The side 44a of the second oil collecting sub-cavity 44 facing the traction wheel 62 is open to receive the sludge in the groove 62a of the traction wheel 62 scraped by the oil scraping blade 30 during the forward rotation of the traction wheel 62. The side 43a of the first oil collecting sub-cavity 43 facing the wire brush 20 is open to receive the oil stain on the wire rope 63 cleaned by the wire brush 20.

[0029] The wire brush 20 is fixed to the partition plate 42 in an inclined manner through a bent plate 21 and is located above the side 43a of the first oil collecting sub-cavity 43 facing the wire brush 20. The wire brush 20 contacts the wire rope 63 to clean the oil stain on the wire rope 63, and the oil stain cleaned by the wire brush 20 can flow into the first oil collecting sub-cavity 43 through the bent plate 21 for storage.

[0030] Two oil scraping blades 30 are stacked on top of each other and installed between the bottom plate 41 of the first oil collecting box 40 and the horizontal plate 12 of the fixing bracket 10 by fasteners. The two oil scraping blades 20 are perpendicular to the wheel surface of the traction wheel 62. Each oil scraping blade 20 is made of a non-metallic material, such as rubber, to prevent abnormal noise from being generated when contacting the groove of the traction wheel. Each oil scraping blade 30 is provided with a fixing hole (not shown in the figure) for the fastener to pass through. The fixing hole is an oblong hole for easy adjustment.

[0031] A number of oil scraping fingers 31 are provided on the contact surface of each oil scraping blade 30 in contact with the groove 62a on the traction wheel 62. Each oil scraping finger 31 is inserted into the corresponding groove 62a on the traction wheel 62 and is slightly in contact with the corresponding groove 62a on the traction wheel 62, so as to facilitate scraping the sludge in the groove 62a on the traction wheel 62.

[0032] The side 53 of the oil collecting cavity 52 of the second oil collecting box 50 facing the traction wheel 62 is open. The second oil collecting box 50 is arranged obliquely at an angle relative to the contact surface A where the oil scraping blade 20 contacts the groove 62a on the traction wheel 62 to receive the sludge in the groove 62a of the traction wheel 62 scraped by the oil scraping blade 20 during the reverse rotation of the traction wheel 62.

[0033] The traction machine 60 of the elevator runs for a long time. As the steel wire rope 63 suspended on the traction machine 60 rotates and is extruded, the oil in the internal rope core will be extruded onto the groove 62a of the traction wheel 62 and form sludge with the dust in the air. The oil scraping device of the present invention is integrally fixed on the traction machine 60. As the traction machine 60 runs, it drives the steel wire rope 63 to move, so that the sludge on the steel wire rope 63 and the traction wheel 62 can be automatically cleaned at the same time. During the monthly maintenance, the oil stains in the first oil collecting box 40 and the second oil collecting box 50 are centrally cleaned to ensure the cleanliness of the use environment of the elevator machine room.
