Description
Technical field
The utility model relates to the monorail mud scraper equipment that uses in a kind of water factory sedimentation basin.
Background technology
The bricklayer that scrapes that mud scraper is used at the bottom of the sedimentation basin pond of waterworks or sewage treatment plant does, and therefore the advantage that mud scraper has that spoil disposal efficient height, energy consumption are low, precipitation water water quality height, land area are economized is used for replacing traditional soil discharging facility.
Mud scraper is divided into chain-type mud scraper, oil pressure reciprocating mud scraper, monorail mud scraper etc.The chain-type mud scraper is to utilize chain drive scraper plate to do to scrape mud continuously; The oil pressure reciprocating mud scraper is to utilize oil hydraulic cylinder to promote linkage, scraper plate is moved reciprocatingly scrape mud; The sludge discharge effects of these two kinds of mud scrapers is general, maintenance cost is higher, service life is shorter, is progressively eliminated at present.The monorail mud scraper is to utilize ring chain pulling mud scraper chassis to move back and forth on guide rail, and described guide rail is laid at the bottom of the sedimentation basin pond, scrapes mud thereby drive scraper plate at the bottom of to the sedimentation basin pond.The monorail mud scraper has that sludge discharge effects is good, the advantage of easy maintenance, long service life, is widely used in the world at present.
See also Fig. 1, this is the schematic diagram that existing monorail mud scraper is disposed at sedimentation basin.Rectangular configuration under the horizon is the sedimentation basin of water factory, is equipped with track 91 at the bottom of the sedimentation basin.The front end 91a of track 91 has two fixed chain wheels 911,912, and the rear end 91b of track 91 has a fixed chain wheels 913.Leading portion chassis 92 and back segment chassis 93 are fixed on the track 91 and can slide along track 91, have cleaning shoe 921 and 931 respectively on leading portion chassis 92 and the back segment chassis 93.The top of track 91 front end 91a just has a draw-gear (motor platform) 94 on ground level.The fixed chain wheels 912 back connection leading portion chassis 92 that draw-gear 94 is set out and walked around quadrant by chain 95, leading portion chassis 92 connects back segment chassis 93 by chain 95 again, back segment chassis 93 again by chain 95 walk around the fixed chain wheels 913 of about 1/2nd circumference successively, the fixed chain wheels 911 of quadrant is got back to draw-gear 94.In other words, chain 95 is annular in the monorail mud scraper.Start draw-gear 94 and control its direction of rotation, can on track 91, move by chain 95 pulling leading portion chassis 92 and back segment chassis 93, by the rear end 91b forward end 91a of track 91 motion is operative orientation, is the backhaul direction by the front end 91a 91b motion to the back-end of track 91.When present segment chassis 92 and back segment chassis 93 moved on track 91, cleaning shoe 921,931 was just scraped the mud operation at the bottom of sedimentation basin.
The monorail mud scraper needs to keep chain 95 to be tensioning state in use, all is at present to adopt the height of adjusting draw-gear 94 and counter weight type tensioning apparatus (not shown) is installed on the pool wall above the sedimentation basin front end track to make chain 95 tensionings.But the scope that the height of adjusting draw-gear 94 can be regulated is little, and the weight of the balancing weight in the counter weight type tensioning apparatus and quantity also are limited, and this makes the chain 95 of monorail mud scraper can not keep very tight tensioning state.
The utility model content
Technical problem to be solved in the utility model provides a kind of ring chain guiding mechanism of monorail mud scraper.
For solving the problems of the technologies described above, the ring chain guiding mechanism of the utility model monorail mud scraper comprises:
Fixed chain wheels 3 is fixed in chain tension frame 1;
The utility model can make the ring chain of monorail mud scraper remain tensioning state easily.

Fig. 2 is the schematic diagram that the utility model cooperates the monorail mud scraper;
Fig. 3 is the schematic diagram of the utility model along orbital direction;
Fig. 4 is the schematic diagram of the utility model vertical track direction.
Description of reference numerals among the figure:
1 is the chain tension frame; 11 is rectangular groove; 2 is movable sprocket wheel; 21 is sprocket shaft; 22 is connecting plate; 3 is fixed chain wheels; 4 is suspension rod; 5 is manual operation machine; 51 is trapezoidal thread; 52 is crank or handwheel; 91 is track; 91a is the track front end; 91b is the track rear end; 911,912,913 be fixed chain wheels; 92 is the leading portion chassis; 93 is the back segment chassis; 921,931 be cleaning shoe; 94 is draw-gear; 95 is chain.
The specific embodiment
See also Fig. 2, Fig. 3 and Fig. 4, wherein Fig. 2 is the schematic diagram that the utility model cooperates the monorail mud scraper, and Fig. 3 is the schematic diagram (front view) of the utility model along track 91 directions, and Fig. 4 is the schematic diagram (side view) of the utility model vertical track 91 directions.The ring chain guiding mechanism of the utility model monorail mud scraper is installed in the top of rear end 91b of the track 91 of monorail mud scraper, comprising:
Among Fig. 2, the fixed chain wheels 912 back connection leading portion chassis 92 that draw-gear 94 is set out and walked around quadrant by chain 95, leading portion chassis 92 connects back segment chassis 93 by chain 95 again, and back segment chassis 93 is walked around the fixed chain wheels 3 of quadrant, the movable sprocket wheel 2 of 1/2nd circumference, the fixed chain wheels 913 of quadrant, the fixed chain wheels 911 of quadrant successively by chain 95 again and got back to draw-gear 94.Chain 95 still remains annular.
When the ring chain in the monorail mud scraper 95 is not in tensioning state, adjustment process of the present utility model is: the crank or the handle 52 that shake and rotate manual operation machine 5, nut rotation connection transmission by trapezoidal thread 51 makes suspension rod 4 rise along plumb line, drive activity sprocket wheel 2 rises within rectangular groove 11, thus tensioning the chain 95 of pile warp activity sprocket wheel 2.Because the existence of connecting plate 22, upper and lower displacement only takes place in movable sprocket wheel 2 in this process, do not have horizontal displacement, also not rotation.
The utility model is by said structure, and the upper and lower displacement of utilization activity sprocket wheel 2 makes ring chain 95 tensionings, has reduced the workload of artificial shortening ring chain 95 quantity, has also reduced the loss of ring chain 95.
