Description of drawings
Fig. 1 is a labyrinth seal structure schematic diagram of the present invention.
Fig. 2 is the structural representation of level board bracing frame of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, 2.
A kind of labyrinth seal structure of water knife device for longitudinal movement rail, it mainly is made up of main cover plate 1, inner cover plate 2 and limit cover plate 3, the two ends of main cover plate 1 are separately fixed on the two ends of track base 4, main cover plate 1 is made up of level board 101 and two downward flangings 102, as shown in Figure 1, among Fig. 1 two guide rail structures, ball-screw 7 is installed in the track base 4, structure of the present invention also can be used for the single-rail structure during concrete enforcement, present embodiment is that example is illustrated with two guide rail structures, and the structure of single-rail can be with reference to design.In order to realize labyrinth seal structure, slide plate 5 of the present invention also must be made respective design, the groove 501 that matches with flanging 102 promptly is set on the limit of slide plate 5, slide plate 5 by thrust slide supporting on guide rail 12, described inner cover plate 2 is linked to each other with vertical side plate 202 by horizonal base plate 201 and forms, wherein horizonal base plate 201 is fixed on the horizontal plane of track base 4, the upper edge of vertical side plate 202 exceeds the lower edge of flanging 102 and is positioned at its inboard, described limit cover plate 3 is by horizontal segment 301, vertical section 302 upwards links to each other with downward vertical section 303 and forms, vertical section 302 upwards links to each other with the both sides of horizontal segment 301 respectively with downward vertical section 303, the described downward vertical section 303 and the side of track base 4 are fixedly linked, the installation site of described horizontal segment 301 is lower than horizonal base plate 201, the described vertical section that makes progress 302 is positioned at the outside of slide plate 5, its upper edge is higher than the lower edge of flanging 102, for the purpose of attractive in appearance, should can be provided with a horizontal bending section 304 that points to slide plate 5 by vertical section 302 upwards, so that whole hermetically-sealed construction looks like an overall structure, in addition, in time discharge from the labyrinth for the ease of the smear metal of splashing in the cutting process, the present invention is provided with the through hole that allows impurity fall on described horizontal segment 301.
During concrete enforcement, in order to increase the debris removal effect, also can be on described slide plate 5, be equipped with slide plate 5 synchronization-moving removings brushes with described horizontal segment 301 relative position places, with moving around of slide plate 5 some are dropped on impurity on the through hole limit and sweep in the through hole and discharge by removing brush.
In order to increase the rigidity of level board 101, the utility model utilizes slide plate 5 as a movable supporting point, for this reason in the installed inside of level board 101 raised line 103, and pulley 502 has been installed in slide plate 5 corresponding positions, pulley 502 is against on the level board 101 all the time to play a supporting role.
For the big-and-middle-sized water knife device of length greater than 4 meters, in order to prevent that level board 101 is because of gravity sag, the utility model has adopted movable supporting, promptly have and prevent its movable support frame 6 because of gravity sag in the installed inside of described level board 101, dress is cut with scissors mutually with the inside bottom surface of level board 101 in the upper end of this movable support frame 6, the action roller 601 of its lower end offsets with the horizontal plane or the horizonal base plate 201 of track base 4, the structural representation of movable support frame 6 as shown in Figure 2, when slide plate 5 moves to described movable support frame 6, pulley 502 on the slide plate 5 is with level board 101 jack-up slightly, the suffered pressure of movable support frame 6 disappear (or very little), edge is at first run into movable support frame 6 and it upwards is pushed in the inner space 13 of slide plate, when slide plate 5 moves apart this movable support frame 6, movable support frame 6 is sagging once more under the effect of gravity, the horizontal plane of the roller of its lower end and track base 4 or horizonal base plate 201 offset and play a supporting role, pulley 502 is remained on the height of level board jack-up can guarantee in the suitable scope that movable support frame 6 just in time vertically props up level board when slide plate 5 leaves the movable support frame of being run into 6.
When the length of turn-screw more than 4 meters the time, in order to prevent that leading screw 7 is because of gravity sag, can adopt turn nut driving mechanism shown in Figure 1, even leading screw 7 keeps motionless, and adding certain pulling force at two stiff ends, it is sagging that leading screw is reduced, and the leading screw movable support frame 8 of the movable support frame that is similar to support level plate 101 6 of some is installed at interval in the bottom of leading screw simultaneously, at this moment, nut 11 links to each other with drive motors 10 on being installed in slide plate 5 by driving-belt 9.
The part that the present invention does not relate to prior art that maybe can adopt same as the prior art is realized.
