コンベア軸自体の軽量化を合間したものに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a screw conveyor on a base, and in particular, by applying a bending moment in a direction that cancels the bending stress due to its own weight, the bending stress is averaged.
This involves reducing the weight of the conveyor shaft itself.

1) A conveyor shaft (4) is rotatably supported by an underwater bearing part (2) provided inside the pool and a bearing part (3) provided in one part outside the pool. One half of the liquid was covered by a circular guide cover (5), and the sediment was deposited at the bottom of the pool due to the transport action of the spiral blade plate (6) installed around the outer circumference of the conveyor shaft (4) driven by the rotation of the conveyor shaft (4). The slag is transported obliquely upward along the guide cover (5) and taken out of the pool.

めて大きい。Because the screw conveyor has such a structure, it cannot be supported at the middle part other than by the bearings (2) and (3) at both ends of the shaft, and moreover, both bearings +21, Dimensions between +31 and 17
Due to special circumstances such as the fact that the conveyor shaft (4) and the vane plate (6) are quite heavy and are applied to the conveyor shaft (4) as an evenly distributed load, the conveyor shaft This bending stress is extremely large compared to other machinery.

) is supported by a rotatable bar and receives a uniformly distributed load in the middle. As is clear from the figure, the bending stress is maximum (σtnax) at the center of the shaft, and therefore, in design, the diameter of the entire conveyor shaft must be made large to match the shaft diameter required for this region. This causes an increase in size and cost.Such problems also occur in screw classifiers and screw pumps having similar structures.

Therefore, such a bending moment (M) in the opposite direction causes a bending stress distribution in the negative direction as shown in Fig. 2 (C), and the sum of the stresses in Fig. The actual bending stress distribution is as shown in d).As shown in the figure, the bending stress (amax) at the center of the shaft decreases by the stress (0m) due to the bending moment (M) in the opposite direction, and becomes (σ1 ).

We will explain how to do this. In this case, as shown in FIG. 3, the bearing area is first placed on the base Oj. At this time, the bearing a1 that supports the front end of the conveyor shaft (1η) is lifted by a crane or the like in a state where it is suspended upward by an appropriate gap (7) from the base Uυ in each ζ water as shown in the figure. With the bearing OI lifted by the width of the gap (1), set the height positions of the bases q1J and 0 moat in advance so that the bottom surface 4 of the bearing box a chrysanthemum comes into close contact with the top surface (to) of the base 03. In this state, align the mounting hole (2) on the rear end of the bearing box with the mounting hole (to) on the rear end of the base 03, and pass the bolt through this. , Attach the spring (A) and nut (To) to the threaded part of the bolt (2) that protrudes downward from the mounting hole.

できる。Next, a crane or the like that is floating the bearing a is driven upward to gradually lower the position of the bearing OI. Then, the inclination of the conveyor shaft surface gradually increases, and the counter spring (C) bends, creating a gap (to) between the rear edge (C) of the shaft inlet Φ and the top surface of the base +13. A bending moment (M) is generated at the rear end of the conveyor shaft (old) in the direction of the arrow (X) according to the amount of compression of the countershaft spring (5), that is, in a direction that cancels out the bending moment due to the conveyor shaft Uη's own weight. The bending moment (M) due to (c) is
Since it is proportional to the amount of deflection c), that is, the amount of inclination of the bearing box I, it can be adjusted to any value by detecting the amount of uplift of the slope of the bearing box A using a dial gauge ■, and the predetermined bending moment When (M) is obtained, the bearing OI
Stop descending, insert spacers corresponding to the widths of the gaps (to) and (to) into the gaps (to) and (2), and place the bearing O1 on the base (II) and the bearing box 041. Fixed to base 0 (to). By the above operation, the conveyor shaft Uη can be installed on the base while the bending moment in the direction of the arrow (X) is applied to the rear end ( ) of the conveyor shaft αη.

This screw conveyor installation method is characterized by applying a bending moment in the direction that cancels out the bending moment due to its own weight, so even in screw conveyors with long distances between bearings, the bending stress applied to the conveyor shaft can be averaged out. Since the maximum bending stress value can be lowered, the conveyor shaft can be made smaller in diameter, and the same applies to screw classifiers and screw pumps, which have a similar mechanism to a screw conveyor and can be treated as a screw conveyor.
