Description
Technical Field
The utility model relates to a sintering machine trolley lower sideboard of steel production auxiliary assembly, especially a hot crack prevention production.
Background
The sintering machine is suitable for sintering operation of large-scale ferrous metallurgy sintering plants, and is mainly suitable for sintering treatment of iron ore powder by large-scale and medium-scale steel enterprises. The reinforcing rib plates of the lower breast board of the original sintering machine trolley are mostly arranged in a 'mouth' shape, and the lower breast board is easy to generate hot cracks and expand along the vertical direction of the rib plate under the working condition of repeated cold and hot alternation, so that the service cycle of the breast board is short, and the sintering quality is influenced. In addition, the breast board and the trolley connecting bolt are arranged in a straight line shape, the bolt tightening torque is too large, the bolt is easy to break due to the alternating change of cold and heat, the tightening torque is insufficient, the breast board is easy to incline, the material leakage and air leakage of the trolley of the sintering machine are caused, the energy consumption is increased, and the production efficiency is influenced; bolt holes for connecting the lower breast board and the sintering machine trolley are all circular, and if size processing deviation occurs, the lower breast board and the trolley cannot be normally installed.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a sintering machine trolley lower sideboard preventing thermal cracks from generating, which is designed under the premise of not changing the original sideboard material (QT450) and the main installation size, reduces the thermal stress concentration of the lower sideboard and avoids the generation and extension of thermal cracks; the arrangement form of bolt holes of the lower breast board is changed, the tightening torque of fastening bolts is reduced, the situation that the bolts are broken due to overlarge tightening torque of the bolts and the breast board is loosened and inclined due to undersize tightening torque is prevented; the shape of the connecting bolt hole is changed, the size processing error is made up, and the mounting efficiency of the lower breast board and the trolley is improved.
The technical proposal of the utility model for solving the technical problem is that: a sintering machine trolley lower breast board capable of preventing thermal cracks from being generated comprises a board body and reinforcing ribs; the plate body comprises a plate surface, an upper plate edge and a lower plate edge; the upper plate edge and the lower plate edge are folded inwards; the method is characterized in that: the reinforcing rib comprises a transverse rib plate, a plurality of vertical rib plates and a plurality of inclined rib plates; the transverse rib plates, the vertical rib plates and the inclined rib plates are connected in a shape like a Chinese character 'mi'; the diagonal rib plates are symmetrically distributed by taking the vertical rib plates as central lines; screw holes for mounting are formed on the upper plate edge and the lower plate edge; two mounting screw holes in the middle of the lower plate are round screw holes, and the straight lines where the two screw holes are located are parallel to the plate surface; the mounting screw holes on the two sides of the lower plate are oval screw holes, and the straight lines where the two adjacent screw holes are located are not parallel to the plate surface.
The length of the lower plate edge extending towards the inner side is greater than that of the upper plate edge.
Compared with the prior art, the utility model discloses following outstanding beneficial effect has:
1. the lower baffle plate of the utility model can effectively prevent the generation of hot cracks, prolong the service cycle of the baffle plate, and prolong the service cycle from about 8 months before transformation to 15 months after on-line use without hot cracks, thereby reducing the spare part cost and labor cost;
2. the bolt holes are designed in a double-row mode, so that the tightening torque of the bolts can be effectively reduced, and a due fastening effect is achieved;
3. part bolt hole design is the ellipse circular, can compensate size processing deviation, realizes the quick installation of lower breast board and platform truck.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the structure a-a of fig. 1.
FIG. 3 is a schematic view of the structure B-B of FIG. 1.
Detailed Description
The invention is further described with reference to the drawings and the detailed description. For convenience of description, the reference is made to fig. 1 as top and bottom, the left side of fig. 3 as outside, and the right side as inside.
As shown in figures 1-3, the utility model comprises a plate body and a reinforcing rib.
The plate body comprises a plate surface 1, an upper plate edge 2 and a lower plate edge 3. The upper plate edge 2 and the lower plate edge 3 are folded inwards. The length of the lower plate edge 3 extending towards the inner side is larger than that of the upper plate edge 2.
The reinforcing rib comprises a transverse rib plate 4, a plurality of vertical rib plates 5 and a plurality of inclined rib plates 6. The transverse rib plate 4, the vertical rib plate 5 and the inclined rib plate 6 are connected in a shape like a Chinese character 'mi'. The inclined rib plates 6 are symmetrically distributed by taking the vertical rib plates 5 as the center line. The design of the Chinese character 'mi' shape can avoid the concentration of thermal stress and prevent the generation of thermal cracks.
In the optimized scheme, the transverse reinforcing plate 4 in the figure 1 is taken as a reference, and the upper vertical reinforcing plate 5 is longer than the lower vertical reinforcing plate 5. The adjacent vertical gusset 5 has different lengths extending inward.
Screw holes for mounting are arranged on the upper plate edge 2 and the lower plate edge 3. The lower plate is connected and fastened with the sintering machine trolley along the screw holes 3, and the upper plate is connected and fastened with the upper breast board along the screw holes 2.
Two mounting screw holes in the middle of the lower plate edge 3 are round screw holes 7, and the straight lines of the two screw holes are parallel to the plate surface 1; the mounting screw holes on the two sides of the lower plate edge 3 are oval screw holes 8, and the straight lines of the two adjacent screw holes are not parallel to the plate surface 1. The screw holes are arranged in double rows, so that the screwing torque of the bolts can be effectively reduced, the overturning force arm of the anti-fence plate is increased, and the fastening effect is achieved. And two middle screw holes are circular, play breast board and platform truck complex positioning action down, and other screw designs are oval, can compensate the size processing deviation of breast board.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
