AI Technical Summary
The lifting pulleys of mine hoists are prone to sludge buildup due to dust and lubricating oil, causing them to rotate unevenly. Existing technologies are not effective at cleaning them.
Scraper blades are installed on both sides of the lifting pulley. Through the push of the booster and the spring, the scraper blades come into contact with the bearing cover and the surface of the main shaft of the hanging rail. When rotating, they scrape off the sludge. The cooperation between the guide seat and the second scraper blade ensures that the sludge is completely removed.
This effectively prevents sludge from accumulating on the lifting pulleys and the main shaft of the hanging rail over a long period of time, ensuring the smoothness of the pulleys and improving rotation efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] like Figures 1 to 4As shown in the figure, a self-cleaning hoist track pulley of mine hoist is applied to the hoist, which comprises a lifting pulley 1 rotatably mounted on a hoist track spindle 3 through a bearing 2, and bearing covers 4 covering the bearing 2 are mounted on both sides of the lifting pulley 1; the hoist track spindle 3 is provided with a boosting part located on both sides of the lifting pulley 1 respectively, and a scraping part is detachably mounted on the boosting part; the scraping part comprises a scraping seat 5, and a scraping plate one 6 is fixedly welded on the scraping seat 5, and the scraping plate one 6 is in contact with the side surface of the bearing cover 4 and the surface of the hoist track spindle 3 under the action of the boosting part; the length of the scraping plate one 6 is greater than the radius of the bearing cover 4, and the scraping plate one 6 does not rotate with the rotation of the lifting pulley 1; the scraping seat 5 is fixedly provided with the scraping plate one 6, and the scraping plate one 6 is in contact with the side surface of the bearing cover 4 and the surface of the hoist track spindle 3 under the action of the boosting part; the length of the scraping plate one 6 is greater than the radius of the bearing cover 4, and the scraping plate one 6 does not rotate with the rotation of the lifting pulley 1. The self-cleaning hoist track pulley of the mine hoist can scrape off all the oil sludge around the bearing cover 4 through the scraping plate one 6 when the lifting pulley 1 rotates, so as to avoid the long-term accumulation of the oil sludge on both sides of the lifting pulley 1, and greatly ensure the smoothness of the lifting pulley 1 when rotating.
[0040] As shown in the figure, Figure 5 The boosting part comprises a guide rod one 7 slidably mounted on the hoist track spindle 3, and a spring one 8 pushing the guide rod one 7 to move vertically downward is sleeved on the guide rod one 7; the boosting part further comprises a guide rod two 9 slidably mounted on the top end of the guide rod one 7, and the end of the guide rod two 9 is a butt plug 10, and the scraping seat 5 is interference-fitted on the butt plug 10, and a spring two 11 pushing the guide rod two 9 to move horizontally to the position of the bearing cover 4 is sleeved on the guide rod two 9. In order to ensure that the scraping plate one 6 is in contact with the side surface of the bearing cover 4 and the surface of the hoist track spindle 3, the boosting part is installed, and the scraping plate one 6 is in contact with the side surface of the bearing cover 4 under the pushing of the spring one 8, and the scraping plate two is in contact with the surface of the hoist track spindle 3 under the pushing of the spring two 11.
[0041] As shown in the figure, Figure 1 , Figure 4 The scraping seat 5 is further fixedly welded with a contact rod 12 located above the scraping plate one 6, and a convex head 13 cooperated with the contact rod 12 is fixedly welded on the side of the lifting pulley 1; when the convex head 13 rotates to the contact rod 12 following the rotation of the lifting pulley 1, the contact between the contact rod 12 and the convex head 13 will compress the spring one 8; wherein the end of the contact rod 12 and the surface of the convex head 13 are both arc surfaces. In order to avoid the oil sludge scraped off by the scraping plate one 6 from accumulating on the scraping plate one 6, the scraping plate one 6 will vibrate once every time the convex head 13 rotates to the contact rod 12 following the rotation of the lifting pulley 1, so as to shake off the oil sludge on the scraping plate one 6 again, thereby avoiding the accumulation of the oil sludge on the scraping plate one 6.
[0042] As Figures 6 to 7 shown, the side of the mud scraping plate one 6 is welded with the obliquely arranged mud guide seat 14 which covers the overhead of the suspension rail main shaft 3. In order to avoid the oil sludge being scraped by the mud scraping plate one 6 and accumulated on the suspension rail main shaft 3, the obliquely arranged mud guide seat 14 is installed to cover the overhead of the suspension rail main shaft 3, at this time the oil sludge will slide along the mud guide seat 14, thereby avoiding the oil sludge being accumulated on the suspension rail main shaft 3.

Whenever the convex head 13 rotates to contact the rod 12 once, at this time, since the mud scraping plate one 6 is not in contact with the bearing cover 4, there will be oil sludge remaining on the upper part of the bearing cover 4, at this time, by installing the mud scraping plate two 15, the part of the bearing cover 4 which is not scraped by the oil sludge will be completely scraped when passing through the mud scraping plate two 15.
[0044] The working principle of the utility model:
[0045] In the application, the motor of the elevator lifts the ore in the mine through the traction steel wire rope 16, as Figure 1 shown, since the steel wire rope 16 is wound on the lifting pulley 1, when the lifting pulley 1 rotates, the bearing cover 4 will permeate the lubricating oil outward, and the air environment under the mine is often accompanied by a large amount of dust, so that the dust falling on the lubricating oil will form oil sludge.
[0046] In order to clean the oil sludge, the mud scraping plate is installed on both sides of the lifting pulley 1; when the lifting pulley 1 rotates, the mud scraping plate one 6 can scrape all the oil sludge around the bearing cover 4, thereby avoiding the long-term accumulation of the oil sludge on both sides of the lifting pulley 1, greatly ensuring the smoothness of the lifting pulley 1 when rotating.
[0047] In the above process of cleaning the oil sludge, in order to avoid the oil sludge being scraped by the mud scraping plate one 6 and accumulated on the mud scraping plate one 6, whenever the convex head 13 rotates to contact the rod 12 once, the mud scraping plate one 6 will vibrate once, thereby the oil sludge on the mud scraping plate one 6 will fall again, thereby avoiding the oil sludge being accumulated on the mud scraping plate one 6; in order to avoid the oil sludge being scraped by the mud scraping plate one 6 and accumulated on the suspension rail main shaft 3, the obliquely arranged mud guide seat 14 is installed to cover the overhead of the suspension rail main shaft 3, at this time the oil sludge will slide along the mud guide seat 14, thereby avoiding the oil sludge being accumulated on the suspension rail main shaft 3; whenever the convex head 13 rotates to contact the rod 12 once, at this time, since the mud scraping plate one 6 is not in contact with the bearing cover 4, there will be oil sludge remaining on the upper part of the bearing cover 4, at this time, by installing the mud scraping plate two 15, the part of the bearing cover 4 which is not scraped by the oil sludge will be completely scraped when passing through the mud scraping plate two 15.
[0048] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
