The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
The chain tension adjusting device of using on described a kind of slat conveyer comprises connecting pin 1, fixedly access slot 2, first median plate 3, base plate 4, second median plate 5, movable access slot 7, right anterior branch fagging 8 and right back stay bearing plate 8B and left front stay bearing plate 13, right front flute profile side board 9 and right back flute profile side board 9B, right front adjusting screw(rod) 10 and right back adjusting screw(rod) 10B, first jam nut 11 and the second jam nut 11B, backing plate 12, right front bearing rib 14 and left front bearing rib 14B, right front setting nut 15 and right back setting nut 15B and right front ledge 16 and right back ledge 16B, the chain tension adjusting device of using on the slat conveyer that is made of said modules places between the intermediate channel and aircraft tail shelf of slat conveyer, and described intermediate channel and aircraft tail shelf are prior art.
The left side as shown in Figure 1 is called the front end of this case, and the right is called the rear end of this case.
Fixedly the front end of access slot 2 is connected with the intermediate channel of slat conveyer by connecting pin 1, and the rear end of movable access slot 7 is connected with the aircraft tail shelf of slat conveyer, fixedly the rear end of access slot 2 connects right front ledge 16 and right back ledge 16B, described right front ledge 16 and right back ledge 16B are commercially available shaped steel, prior art.In the outside of right front ledge 16 with right front flute profile side board 9 bound edges, in the outside of right back ledge 16B with right back flute profile side board 9B bound edge, both bound edge length L=110~130mm (the best is selected L=120mm).Be wrapped in right front ledge 16 outsides and right back flute profile side board 9B when being wrapped in right back ledge 16B outside in right front flute profile side board 9, guarantee right front flute profile side board 9 with the side board inner width W1 between the right back flute profile side board 9B greater than right front ledge 16 with the outer wide W2 of the ledge between the right back ledge 16B, desirable W1-W2=3.0~5.0mm, the interior high h4 of right back flute profile side board 9B (or right front flute profile side board 9) is greater than the outer high h3 of right back ledge 16B (or right front ledge 16), desirable h4-h3=3.0~5.0mm simultaneously.At the fixing middle part of access slot 2 first median plate 3 is arranged, long otch 6 backs that (as the welding) base plate 4 in first median plate 3 bottoms that is connected passes on right front ledge 16 and the right back ledge 16B contact with the right front flute profile side board 9 on both sides and the inwall of right back flute profile side board 9B, because the big 2.0~3.0mm of thickness of the aspect ratio base plate 4 of long otch 6, and the length of long otch 6 is 140-160mm (the best is selected 150mm), guarantee that base plate 4 can pass long otch 6, and can move freely.Near second median plate 5 positions of base plate 4 between the interior prominent point of right front ledge 16 and right back ledge 16B central authorities, the rear end scantling of structure of the second median plate 5 that links to each other with movable access slot 7 front ends is identical with the intermediate channel scantling of structure of slat conveyer, connects the aircraft tail shelf of slat conveyer indirectly with second median plate 5.
On right front flute profile side board 9, be fixed with backing plate 12, right front bearing rib 14 is connected with backing plate 12 mutually with right anterior branch fagging 8, and on right anterior branch fagging 8, be processed with the hole (circular hole or screw) that to pass right front adjusting screw(rod) 10, intrinsic left front stay bearing plate 13 and right front bearing rib 14B on left front flute profile side board 9C, on left front stay bearing plate 13, be processed with the hole (circular hole or screw) that to pass right front adjusting screw(rod) 10, right front adjusting screw(rod) 10 is installed in the hole of right anterior branch fagging 8 and left front stay bearing plate 13, both sides at right anterior branch fagging 8 are screwed with first jam nut 11 and right front setting nut 15 on right front adjusting screw(rod) 10, be screwed with the second jam nut 11B on one side of left front stay bearing plate 13 on right front adjusting screw(rod) 10.
Identical in the connection structure on the right back adjusting screw(rod) 10B with connection structure on the right front adjusting screw(rod) 10.
Fixedly access slot 2 is connected with right front adjusting screw(rod) 10 of movable access slot 7 usefulness and right back adjusting screw(rod) 10B, the rear end scantling of structure of the second median plate 5 that cause links to each other with the front end of movable access slot 7 is identical with the intermediate channel scantling of structure of slat conveyer, simultaneously because of the ledge between right front ledge 16 and the right back ledge 16B wide W2 and fixing access slot 2 outer wide consistent outward, front end that so both can assurance activity access slot 7 can freely stretch in the rear end of fixing access slot 2, can guarantee that again the coal phenomenon can not appear leaking in slat conveyer when carrying coal.
During enforcement, according to shown in the accompanying drawing chain tension adjusting device on described a kind of slat conveyer is assembled between the intermediate channel and aircraft tail shelf of slat conveyer, connecting pin 1 is linked to each other with intermediate channel, movable access slot 7 links to each other with aircraft tail shelf.Starting slat conveyer can export coal continuously, when the scraper chain of slat conveyer in use because of the elongation of chain stress deformation, cause that the both sides chain on the slat conveyer is asynchronous, when jumping chain or falling fault such as chain, unclamp first jam nut 11 and the second jam nut 11B on right front adjusting screw(rod) 10 and the right back adjusting screw(rod) 10B this moment, pull right front setting nut 15 right back setting nut 15B, movable access slot 7 is drawn back, thereby promote aircraft tail shelf to stepping back, the securable chain of drawing back of aircraft tail shelf, when the tensioning degree of chain meets the demands, tight first jam nut 11 and the second jam nut 11B, slat conveyer i.e. operation or use as usual, reaches purpose of the present invention.
Declared utility model patent simultaneously with this case.
