Abstract
The utility model relates to a guide wheel tension structure of slag extractor of boiler, in particular to water-proof guiding tension wheels of slag extractor of boiler. The guiding wheels tension mechanism comprises a guide wheel shaft (2) and two guide wheels (1). Both ends of the guide wheel shaft (2) are provided with a chain tension adjuster comprising an adjusting slider (3) and a slider support (6). The two guide wheels (1) and the guide wheel shaft (2) are connected together. The guide wheel shaft (2) is supported in the adjusting slider (3) with the bearing (4). The guide wheel shaft rotates relatively to the adjusting slider. The guide wheel shaft (2) is provided with a watertight ring (5). The watertight ring (5) is arranged on the guide wheel shaft between the guide wheel (1) and the adjusting slider (3). The utility model has the advantages that troubles of the tension guide wheels in the prior art are effectively reduced and the operation reliability of the cinder dragging machine is improved.
Description
Technical field
The utility model relates to boiler dragveyer tensioner Guiding wheel structure, mainly proposes a kind of boiler dragveyer waterproof tensioner guide wheel.
Background technology
The boiler dragveyer is the slag equipment that drags for of power plant boiler, and it is a chain scraper type conveying machinery of the slag in the water being pulled and is delivered to out the fixed position.The afterbody of dragveyer is provided with the tensioner guide wheel of adjusting the chain degree of tightness, original tensioner Guiding wheel structure as shown in Figure 1, two guide wheels 1 are set on its guide wheel shaft 2, guide wheel 1 is bearing on the guide wheel shaft 2 by bearing 4, be to be provided with bearing 4 in the guide wheel, guide wheel 1 rotates relative to guide wheel shaft 2, the two ends of guide wheel shaft 2 have the slide block 3 of adjustment and slider bracket 6, adjusting slide block 3 can drive guide wheel shaft 2 and move along the chute of slider bracket, by changing the spacing between guide wheel and the adjacent guide wheel (not shown), adjust the elasticity of chain; Promptly when needs are adjusted the chain elasticity, adjust slide block 3 and move, make guide wheel 1 and the spacing between the head sprocket on the guide wheel shaft obtain changing, thereby make chain tensioner degree obtain adjusting relative to slider bracket 6.Chain will pass through from the slag case in the dragveyer running; make to speckle with buck on the chain and bring on the guide wheel 1, flow in the guide wheel bearing, destroyed bearing lubrication bearing is damaged thereby have buck often; the tensioner guide wheel is broken down, reduced the functional reliability of boiler dragveyer.
Summary of the invention
The purpose of this utility model is to propose a kind of boiler dragveyer waterproof tensioner guide wheel, by the architecture advances to the tensioner guide wheel, prevents that buck from entering in the bearing, prolongs tensioner guide wheel service life, improves the functional reliability of dragveyer.
The utility model is finished the technical scheme that its invention task taked: the tensioner guide wheel includes guide wheel shaft and two guide wheels, the guide wheel shaft two ends have by adjusting the chain tensioner degree guiding mechanism that slide block and slider bracket constitute, wherein, two guide wheels connect one with guide wheel shaft, guide wheel shaft is bearing in by bearing and adjusts in the slide block, guide wheel shaft rotates with respect to adjusting slide block, has drip ring on guide wheel shaft.
During the work of the utility model tensioner guide wheel, because two guide wheels connect one with guide wheel shaft, guide wheel shaft together rotates with guide wheel, guide wheel shaft is bearing in by bearing and adjusts in the slide block, and when adjusting slide block and rotate, bearing plays the supporting lubrication at guide wheel shaft, bearing is arranged on to be adjusted in the slide block cavity away from chain, prevent the damage of buck, on guide wheel shaft, have drip ring, prevent that further buck from entering bearing generation damage along axle bearing.The boiler dragveyer waterproof tensioner Guiding wheel structure that the utility model proposes can effectively reduce the fault rate of tensioner guide wheel, has improved the reliability of dragveyer work.
Description of drawings
Accompanying drawing 2 is the utility model boiler dragveyer waterproof tensioner Guiding wheel structure schematic diagram.
Among the figure, 1, guide wheel, 2, guide wheel shaft, 3, adjust slide block, 4, bearing, 5, drip ring, 6, slider bracket.
The specific embodiment
The embodiment that provides is in conjunction with the accompanying drawings further specified the utility model:
As shown in Figure 2, the tensioner guide wheel includes guide wheel shaft 2 and two guide wheels 1, guide wheel shaft 2 two ends have by adjusting the chain tensioner degree guiding mechanism that slide block 3 and slider bracket 6 constitute, adjusting slide block 3 can move relative to slider bracket 6, by changing the spacing between guide wheel shaft upper block and the adjacent guide wheel, the elasticity of dragveyer chain is adjusted.Wherein, two guide wheels 1 constitute integrative-structure with guide wheel shaft 2 key connecting, bearing 4 is positioned at the cavity of adjusting slide block 3, guide wheel shaft is bearing in by bearing and adjusts in the slide block, guide wheel shaft rotates with respect to adjusting slide block, and the cavity of adjusting slide block 3 is sealed with encapsulant, has drip ring 5 on guide wheel shaft 2, drip ring 5 produces damage in order to prevent that buck from moving in the bearing along guide wheel shaft to bearing on the guide wheel shaft 2 between guide wheel 1 and the adjustment slide block 3.
Claims (1)
