Guaranteeing to provide the storage tank of the 2nd kind of version among Fig. 7 under the constant situation of basic function.In structure shown in Figure 7, the structure of first storage tank 8 on the frame is constant, 16 of second storage tanks on the lath 10 by U-shaped become that sidewall by the bottom surface of a horizontal direction and a vertical direction constitutes horizontal L shaped, all relative lath 10 length directions of the sidewall of two L shaped storage tanks are positioned at the outside of second storage tank, and two inside surface of side wall are respectively with matching with the outer surface of its corresponding first storage tank on the frame, realize qualification thus, simultaneously guide effect is played in the motion that fluctuates of lath 10 lath 10 relative shelf position.Two of two second storage tanks 16 sidewalls all are positioned at the stave lengths direction outside on Fig. 7 middle plate strip 10, also two sidewalls can be arranged on stave lengths direction inboard, and the spacing technique effect with guiding that it played is identical.
Because whole sealing surface is spliced mutually by 10 laths 10, in order further to guarantee the integrality of whole sealing surface, make and face the good engagement state of maintenance between the lath 10 mutually, avoid because of the mutual too big and stuck bullet of the changing of the relative positions not, and whole sealing surface can both well be fitted with the bottom surface of chassis bottom girder 4, therefore, as Fig. 8, shown in Fig. 9, also be arranged at intervals with two through holes 21 that run through its width on the middle part horizontal segment of each lath 10, and by in formed two passages that run through whole seal f ace width direction that join successively by the through hole 21 in each lath 10, steel wire or steel wire rope 20 being set, and all laths 10 are concatenated into one " chain structure ", like this, both guaranteed the stable of each lath 10 relative position relation, force all laths 10 when fitting, to form interlock again with chassis bottom girder 4, guaranteed the continuity and the integrality of whole sealing surface distortion, eliminated lath jammed phenomenon in location free procedure simultaneously and taken place.19 is the steel wire in the containing hole that is provided with on the two outermost laths or the dop at steel wire rope two ends among the figure.
After utilizing steel wire or steel wire rope 20 that all laths 10 are concatenated into one " chain structure ", in the whole sealing surface location free procedure that constitutes by all laths 10, be subjected to force interlock to influence, relatively rotate occurring between the adjacent slat 10, therefore, rotational deformation for fear of the 15 pairs of laths 10 of tilting section that are positioned at lath 10 length direction two ends causes interference, and as shown in Figure 10, the width of tilting section 15 is less than the width of lath 10 by-level sections.
After all laths 10 are concatenated into one " chain structure ", all laths in the whole seal cover board are being carried out in the applying process with chassis bottom girder bottom surface, can link mutually, thereby integrality and continuity when forcing to have guaranteed whole seal cover board distortion, for the excellent sealing of device for frame head and tail of sintering provides further guarantee.In addition, after each lath is concatenated into " chain structure ", also help to overcome the impurity obstruction that unsteady distortion is produced to lath of facing mutually in the lath interface slit.
Figure 11,12,13 shows the 4th kind of embodiment of the present invention.At first need to prove, lath 10 length directions in this embodiment have with embodiment 3 in the identical three-stage structure of lath.
In this embodiment, as shown in FIG., two sides of lath 10 middle part horizontal segments have adopted the circular arc 23 of evagination of mutual coupling and arc groove 22 structures of indent respectively, like this, when facing the 10 mutual splicings of two laths mutually, the side 23 of the evagination of one of them lath 10 is inserted in the arc groove 22 of indent of another lath 10, make and form the arc interface structure between two laths 10, like this, when lath 10 is subjected to the compressing of chassis bottom girder to float distortion, facing two laths 10 mutually can relatively rotate around its arc interface, makes between the adjacent slat 10 structurally interrelatedly thus, and links mutually when unsteady.
Utilize steel wire or steel wire rope 20 formed " chain structure " to compare with embodiment 3, in the present embodiment with face mutually between the lath 10 by the arc interface join can realize equally between the lath 10 interrelated on the structure, interlock mutually in the location free procedure is to guarantee integrality and the continuity in the whole seal cover board deformation process.And this arc interface structure also has good seal, relatively rotates advantage flexibly.Arc interface structure form also helps and prevents that impurity from falling into interface, simultaneously, faces lath mutually and does to relatively rotate by the arc interface and also help overcoming the obstruction that impurity caused in the interface, even if fall into some impurity in the interface, also can not make interface stuck.
Rotate because of facing mutually to exist mutually between the lath 10, therefore, as shown in figure 12, and with reference to Figure 10, the width of lath 10 two ends tilting sections 15 and the width of U-lag can be avoided causing interference to facing relatively rotating between the lath 10 mutually less than the width of its middle part horizontal segment like this.
The foregoing description should not be construed as limitation of the invention just for thought of the present invention is described.
