Example Embodiment

[0024] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and drawings therein are essentially for illustrative purposes, rather than limiting this invention.
[0025] Such as figure 1 As shown, the present invention includes a moving device 1, a bracket 2 and a scraper chain 3. The mobile device 1 can select the coal charging cart, the coke pushing cart or the SCP integrated machine on the side of the coke oven 4 according to the situation. The main function of the mobile device 1 is to adapt to local conditions and can be easily moved, so as to realize the cleaning of the remaining coal of the coke oven 4 stove 41.
[0026] Such as figure 2 versus image 3 As shown, the bracket 2 is a supporting structure. The two ends of the bracket 2 are respectively installed with a tension sprocket 5 and a driving sprocket 6, and a reduction motor 7 is also installed on the bracket 2, and the reduction motor 7 and the driving sprocket 6 drive Connect and drive the sprocket 6 to rotate. The driving sprocket 6 and the tensioning sprocket 5 are both left-right symmetrical structure, and both sides are equipped with scraper chain 3, the structure of scraper chain 3 is as Figure 4 As shown, the arrow direction in the figure is the rolling direction of the scraper chain 3. There are two scraper chains 3, which are arranged symmetrically on both sides of the bracket 2 respectively. The scraper chain 3 surrounds the tension sprocket 5 and the drive sprocket 6 to form a closed loop chain. The tension sprocket 5 and the drive sprocket 6 are located in the closed space of the closed chain, and the reduction motor 7 is located on one side of the closed space.
[0027] Scrapers 8 are installed on the outside of the scraper chain 3 at intervals. The scrapers 8 are evenly spaced. When the scraper chain 3 circulates, a scraping surface is formed to continuously scrape off the excess on the stove 41 of the coke oven 4 layer by layer. coal. In order to prevent the scraper 8 from scraping against the countertop 41 of the coke oven 4, the rotating outer edge of the scraper 8 is provided with an isolating steel bar 9, and the gap between the isolating steel bar 9 and the outer edge of the scraper 8 is 5-15 mm. The isolation steel strip 9 is only arranged on the side of the scraper 8 that scrapes the remaining coal, and is installed on the bracket 2 by welding or threaded connection. The isolation steel bar 9 is perpendicular to the scraper 8, that is, parallel to the movement direction of the scraper 8, and the remaining coal is poured along the movement direction of the scraper 8, so that when the scraper 8 scrapes the remaining coal, the isolation steel bar 9 will not It creates obstacles and can also lead to the dumping of remaining coal.
[0028] The bracket 2 supports the scraper chain 3 to form an independent structure for scraping the remaining coal. One end of the bracket 2 is installed on the moving device 1 through the turning mechanism 10. The turning mechanism 10 can be realized by a motor-driven linkage mechanism to achieve accurate positioning, but the structure is relatively complicated. In this embodiment, the turning base 11 is used in conjunction with the hydraulic cylinder 12 to achieve turning, such as Figure 5-Figure 7 Shown. The flip seat 11 includes two axle seats, one axle seat is fixedly installed on the top of the mobile device 1, the other axle seat is welded to the bracket 2 through the connecting plate 13, and the two axle seats are processed with corresponding holes, and the pin is used. Passing through the holes on the two shaft seats, a turning axis for the support 2 to turn around the moving device 1 is formed.
[0029] A hydraulic cylinder 12 is installed on the top of the mobile device 1 at the rear side of the turning base 11. The hydraulic cylinder 12 is fixed by the base 14. The hydraulic cylinder 12 can rotate around the base 14, and the hydraulic cylinder 12 is provided with a movable piston rod 15 The exposed end of the piston rod 15 is pivotally connected to the connecting plate 13 via a pin, so that the piston rod 15 is connected to the bracket 2. Driven by hydraulic power, the hydraulic cylinder 12 can extend or retract the piston rod 15 to drive the connecting plate 13 and the support 2 to move. Since the connecting plate 13 is simultaneously restricted by the turning seat 11, the support is pushed by the piston rod 15. 2 It can turn around the turning seat 11 to form a turning movement, which is convenient for turning the bracket 2 as a whole to the remaining coal and coal pile on the countertop 41 of the coke oven 4.
[0030] If the stove 41 of the coke oven 4 is equipped with a stove coal belt conveyor, the remaining coal is directly scraped onto the conveyor by the present invention and transported away by the conveyor. When the coke oven 4 stove 41 is not equipped with a stove coal belt conveyor, it is also necessary to separately set a movable skip 16 and a coal collecting bucket 17 on the mobile device 1 to facilitate storage and transportation of the remaining coal.
[0031] The movable skip 16 can be telescopic in the mobile device 1 and is located on the upper part of the coal collecting bucket 17. Rollers 18 are fixedly installed on both sides of the upper part of the movable skip 16 through a shelf, and raceways 19 are installed on the two sides of the mobile device 1 in dependent positions. The rolling wheels 18 are fitted in the raceways 19 and can roll back and forth in the raceways 19. The movable skip 16 is also connected to the inner side of the mobile device 1 with the piston rod 21 of the hydraulic cylinder 20. The hydraulic cylinder 20 is installed on the mobile device 1. The protruding end of the piston rod 21 is connected with the movable skip 16, and the expansion direction is parallel to Raceway 19. The hydraulic cylinder 20 and the piston rod 21 can be installed in pairs or on one side, which is determined according to actual needs. When working, the hydraulic cylinder 20 is driven by hydraulic power to push the piston rod 21 to extend. The movable bucket 16 is pushed by the piston rod 21 of the hydraulic cylinder 20 to extend out of the moving device 1 and is located under the coke oven 4 stove 41. The movable skip 16 has an inlet at the upper part and an outlet at the lower part. The inlet corresponds to the position where the remaining coal of the coke oven 4 stove 41 is scattered, and the outlet corresponds to the inlet of the coal hopper 17.
[0032] After the movable skip 16 introduces the remaining coal from the falling surface of the stove 41 into the coal collecting bucket 17, the remaining coal can be directly discharged through the outlet of the coal collecting bucket 17 or transported away by the mobile device 1. A pair of gates 22, 23 are connected to the outlet of the coal collecting bucket, and gears that mesh with each other are arranged on the rotating shafts of the pair of gates 22, 23 to realize mutual cooperation and separation. Any one of the pair of gates 22 and 23 (the gate 23 in this embodiment) is pivotally connected to a piston rod 25 of a hydraulic cylinder 24, and the hydraulic cylinder 24 is pivotally mounted on the moving device 1. When the gate needs to be clocked in, the hydraulic cylinder 24 drives the piston rod 25 to retract under the drive of hydraulic power, and the piston rod 25 pulls the gate 23 to rotate through the pivot shaft. When the gate 23 rotates and clocks in, the gate 22 is driven by the meshing gears on the rotating shaft. Rotate to open the outlet of the coal hopper 17. When the outlet of the coal collecting bucket 17 is closed, the piston rod 25 extends, and the gates 22 and 23 rotate relatively to close the outlet together.
[0033] The invention adopts the bracket 2 to be turned over and installed on the mobile device 1, which is convenient to move and clean up the remaining coal. The bracket 2 is provided with a cyclically rolling scraper chain 3 and a scraper 8, which can quickly and conveniently scrape the remaining coal out of the stove when rolling 41. In this way, safe and efficient residual coal cleaning is realized. The present invention realizes fully mechanized operation, with high efficiency, low labor intensity, safer and more environmentally friendly, and lower accident rate.
