The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 to Fig. 3, a kind of roller type plate chain cinder conveyer, comprise actuating device 1, drive sprocket set 2, driven chain wheels 3, flight chain 4, guide rail 5, actuating device 1 drives drive sprocket set 2,3 of drive sprocket set 2 and driven chain wheels are connected by flight chain 4, and drive sprocket set 2, driven chain wheels 3 respectively are furnished with two sprocket wheels that are meshed with the standard round loop chain.
Described guide rail 5 is top and following each two, upper and lower guide rail 5 is installed in respectively on rectangular cross section tank 7 interior both sides cell wall supports and the bottom built-in fitting, two flight chains arranged side by side 4 along top guide rail 5 and below guide rail 5 operations, top flight chain 4 is return leg, and below flight chain 4 is work branch; Between two flight chains 4, be installed with scraper plate 47.
Described flight chain 4 comprises roller 42, inner chain sheet 41, outer chain sheet 48, scraper plate 47, bearing pin 44, referring to Fig. 4, Fig. 5, two apodema sheets 41 of flight chain 4 and outer chain sheet 48 (GB/T8350-2008) as the basis, have carried out specific aim design according to characteristics such as mediumand smallscale industrial boilers room cinder wet type conveyings take national standard " conveyer chain, annex and sprocket wheel ".Every group of flight chain 4 mainly by four rolling 42, six chain sheets 41,48 and a slice scraper plate 47 and bearing pin 44 etc. form.Scraper plate 47 is " U " shape on fix shaft 46 is fixed in inboard outer chain sheet 48 between the duplex chain, can prevent that slag from overflowing from both sides in course of conveying, and strengthen the integral rigidity of flight chain 4.
The roller 42 of described flight chain 4 is that a side has edge wheel, and described roller 42 can be erected at operation on the guide rail 5, is convenient to the location with the roller 2 that a side is had chance with.Because guide rail 5 is held roller 42, just can control the scraper plate 47 of flight chain 4 and the distance of tank 7 bottoms, when flight chain 4 moves in Rectangular Water Trough 7 bottoms of retaining, can keep 3～5 millimeters gap between scraper plate 47 and tank 7 bottoms.
The roller place of described flight chain 4 is comprised of bearing pin 44, axle sleeve 45, roller 42 and lining 43, outside the bearing pin 44 axle sleeve 45 is housed, and lining 43 is housed in the roller 42, and lining 43 is sleeved on the axle sleeve 45.Wherein lining 43 has adopted compound oil-free lubrication material, can be more satisfactoryly at the contain slag and the water trough work of water quality meta-acid, its wear resisting property is good.Simultaneously, as the lining 43 of consumable accessory, and 42 on roller is flush fit, and 45 on axle sleeve can relatively rotate, and may wear to a certain degree, can pound out from roller 42 easily, changes new lining.
Described flight chain 4 turns to the slant operation place by level, or by roll steer level place, arc fixedly is housed on the bilateral cell wall of described guide rail 5 tops presses rail 6, roller 42 bottoms of flight chain 4 are held by guide rail 5, roller 42 tops are pressed rail 6 to push down by arc, make flight chain 4 press rail 6 operations along guide rail 5 and arc.
The working process of the utility model roller type plate chain cinder conveyer is:
According to the layout of conveyer, can determine its length of run and flight chain (group) quantity.Every group of (two pitches) flight chain 4 relies on four edge wheel 42 rolling-operation on default guide rail 5 is arranged, and its friction coefficient is little, and guide effect is good.Flight chain 4 keeps approximately 3～5 millimeters gap between scraper plate 47 and tank 7 bottoms when the operation of Rectangular Water Trough 7 bottoms of retaining, slag is slowly pushed towards service direction.
Under actuating device 1 drives, drive sprocket set 2 drives flight chain 4 along the upper and lower guide rail 5 continuous circulations operation that places rectangular cross section tank 7, top flight chain 4 is return leg, below flight chain 4 is work branch, will sink to the cinder output of bottom land by means of the equidistant scraper plate 47 that is fixed on the carrier bar.Turn to the slant operation place at chain 4 by level, or by roll steer level run place, for the chain 4 that overcomes tensioning lifts, be welded with arc on the bilateral cell wall of guide rail 5 tops and press rail 5, with control flight chain 4 upper rollers 42 trends.The driven chain wheels 3 of afterbody are equipped with tightening device, by adjusting screw(rod), can keep the suitable degree of tension of flight chain 3.
When in case flight chain 4 may transship in the tank 7 unexpected stuck phenomena of appearance, the utility model has adopted double overload protection measure, that is: 1) connect hinge wheel between the drive sprocket set 2 and the safety pin of wheel hub will be cut off out voluntarily at actuating device 1, hinge wheel idle running, flight chain is eliminated tractive force at once; 2) set up the overload protection element in the electric control system.
Actuating device support, tightening device support and the guide rail of the utility model roller type plate chain cinder conveyer, arc press rail etc. can adopt welding manner to be welded on the bottom land, cell wall of corresponding site.
It below only is preferred embodiment of the present utility model; be not be used to limiting protection domain of the present utility model; therefore, all any modifications of within spirit of the present utility model and principle, doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
