2. Description of the Related Art A pallet truck structure in a Dwyroid type sintering machine has a rectangular body frame, that is, a material loading width and a lower suction opening width are equal, and axles and wheels are extended on both sides of the frame and laid on both sides of the opening. On the rail that has been set. Therefore, the width of the pallet is the width of the suction opening, and a countermeasure for preventing air leakage at the side portion due to the tightening of the sintering process is usually a method such as enlarging or blinding the great bar at the side portion.

A pallet truck in which the material loading width is wider than the suction opening width for the purpose of improving productivity and improving quality and yield has been proposed in Japanese Patent Laid-Open No. Hei 5-71879. The more expanded portion is one in which the opaque plate projects on both sides of the rectangular bogie main body frame. In such a method, since the passing wind speed in the raw material bed becomes discontinuous, the effect corresponding to the widening cannot always be obtained. On the other hand, as shown in Japanese Patent Application No. 8-125555, a system in which the bogie side wall structure itself is changed and the material loading width is expanded in consideration of the wind speed distribution has been proposed.

However, when the pallet truck is to be widened by the side wall structure, the width of the pallet truck is naturally limited. Above all, the interference margin between the supply / discharge sprocket wheel and the side wall of the bogie main body is a large rate-determining factor due to large equipment modification, but usually about 250 mm can be secured. What matters rather is the height of the bogie frame body. The frame height of the bogie is usually 300 ~
It is about 500 mm. Since the side wall extends in the vertical direction in the conventional method, there is no problem in attaching and detaching the great bar and the seal bar.

However, when the side wall is formed into a curved surface, it is necessary to consider these workability. Referring to FIG. 3, on the curved side wall 2 having a bogie main body height 1, a vertical portion 4 for mounting the claws of the great bar 3 and a vertical portion 7 for securing a space for tightening the fixing bolt 6 of the seal bar 5 are provided. Only 9 trolley heights are required and contribute to the bending, ie the expansion 8 of the material loading width. There is also a limit on the bending inclination angle 10 of the bogie height 9, and the larger the inclination angle, the greater the thermal stress of the concave portion 11 inside the curved side wall surface. Therefore, a truck with a low height has a small width for widening, and a large result may not be expected for the equipment modification.

SUMMARY OF THE INVENTION In order to solve these problems, the present invention focuses on the structure of an air seal cover for storing an air seal bar and the positional relationship with a pallet side wall. Since the starting point of the side wall is slid in the direction in which the width is widened in advance by being provided inside the lower portion of the pallet, the curvature of the side wall is remarkably reduced, and the restriction on the height of the carriage of the wide pallet is removed. Since the air seal cover is installed inside the lower part of the pallet, the inner end of the fixing bolt of the air seal bar is exposed to the high temperature dust atmosphere. I do.

That is, in the pallet side wall structure, the inclination downward from the great bar charging portion is gently taken, and the pallet side wall is branched at the lower portion of the pallet, one vertically downward and the other once toward the pallet center. After extending horizontally, the air seal cover is formed by extending vertically downward.

Further, the air seal bar has a slight increase in temperature as compared with the conventional structure, so that a gap is provided between the air seal cover and the air seal bar to form an air heat insulating layer, thereby reducing the temperature of the air seal bar. Prevent rise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A seal bar is originally provided on a pallet truck side to seal a sintering exhaust gas suction portion, and is conventionally provided outside a side wall in consideration of workability and atmosphere. . However, the width of the air seal cover itself is nearly 200 mm, and in any case, the outer wall on the side wall side is exposed to the temperature of the sintering exhaust gas and heated to around 300 ° C. In addition, the life of the seal bar has been improving recently, and it is about 5 to 6 years, and the side wall and the great bar have the same life. Therefore, the maintenance of the seal bar can be performed at the same time as these. Although slightly worse, the seal bar fixing bolts can be installed inside the pallet, thereby greatly reducing the curvature of the side wall when widening. Specifically, referring to FIG. 1, the side wall 2 is branched at the lower portion of the pallet, and the air seal cover 11 is formed.
Is formed, whereby the fixing bolt 6 of the seal bar 5 becomes inside the pallet.

As described below, the width can be sufficiently widened even in consideration of the vertical portion of the upper wall of the great bar mounting portion. Atmospheric countermeasures are to install a simple lid 12 around the fixing bolt to prevent dust from entering, and to provide a slightly rising air seal cover temperature, it is sufficient to provide an air insulation layer 4 between the air seal cover and the seal bar. It is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 2, a structure around a seal bar of an air seal cover-incorporated widening truck will be described. The fixing bolt 6 of the seal bar 5 is covered with a lid 12 to protect it from dust atmosphere, and the lid 12 is fixed to the air seal cover 11 with a set screw 13. Also, the air seal cover 11
An air insulation layer 14 is provided between the seal bar 5 and the seal bar 5 to reduce the temperature load on the seal bar 5. By adopting such a structure, the limitation on the height of the bogie when widening is practically eliminated.
