Abstract

PURPOSE:To facilitate angle adjustment and to eliminate the need to cut an excessive length part by suspending a shoot pipe temporarily from the lower end of a discharge shoot through a stay and an U bolt. CONSTITUTION:To the reverse surface of a flange 5 provided to the lower end of the discharge shoot 1, a ring 6 having slightly greater internal diameter than the external diameter of the shoot pipe 3 to be coupled is fixed. In the reverse surface of the ring 6, plural stays 8 are impalanted and U bolts 9 implanted in the outer circumferential surface of the upper end of the pipe 3 are hooked by them to suspend the pipe 3 from the ring 6. In this case, a gap 11 is formed between the pipe 3 and ring 6, so the pipe 3 is slanted at a fairly large angle as shown by broken lines. Then, a neck flange 12 is slid to fix a flange part 13 to a flange 15 at the upper end of a receiving pipe 2, and the shoot 1 and pipe 2 are coupled together. Lastly, welding 16 is carried out in the gap 11 to complete the fitting operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a chute pipe that connects an upper discharging chute and a lower receiving section pipe when injecting grain or other grain into a silo or discharging it from a silo.

For example, as shown in Figure 1, the payout chute (1
) and the receiving pipe Q) of the lower receiving section, the middle must be connected with a chute pipe (3). In order to fix such a chute pipe (3) to the lower end of the dispensing chute (1) and the upper end of the receiving pipe (2), conventionally, the adjustment length was set by 100 sss or more from the standard dimension in advance as an adjustment allowance for adjusting the length. Since we had prepared pipes with extra length and installed them together with the actual parts, we had to cut off the excess length during installation, resulting in a lot of waste. Also, to adjust the mounting angle, the adjustment was done using the insertion part of the flange into which the upper and lower ends of the chute pipe are inserted, but since the adjustment allowance for the 7-lunge part is extremely small, if the adjustment angle is large, please refer to Figure 2. As shown in Figure 5, the chute pipe (3) had to be cut in the middle and the cut ends (4) were butted together and welded, making the work extremely difficult.

The present invention solves the problems of such conventional mounting methods,
It is intended to provide an easy installation method for on-site construction.
A ring with an inner diameter slightly larger than the outer diameter of the chute pipe to be connected is fixed to the flange provided at the lower end of the dispensing chute at the top, and a ring having an inner diameter slightly larger than the outer diameter of the chute pipe to be connected is fixed to the flange provided at the lower end of the dispensing chute at the top. The chute pipe is suspended from the ring by engaging the U bolt attached to the outer circumferential surface, and the flange of the neck 7 flange, which is slidably fitted on the outer circumference mK of the lower end of the chute pipe, is connected to the upper end of the receiving pipe. A silo chute characterized in that the chute pipe is mounted between the ring and the neck flange, and then the upper end of the chute pipe is fixed to the ring by welding between the ring and the chute pipe. This relates to a method of installing pipes.

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1, 3, and 4, the dispensing chute (1) at the top should be connected to the lower surface of the seven flange (5) provided at the lower end of the dispensing chute (1). A ring (6) having an inner diameter slightly larger than the outer diameter of the chute pipe (3) is fixed with bolts (7) and nuts. This ring (6) K indicates No. 41iiC51
A plurality of stays (8) are provided protruding from the lower surface of C.

On the other hand, a plurality of U poles (9) are protruded from the outer peripheral surface of the upper end of the shoot vibe (3). Ring bolt (9)
This is the welded part. When this U bolt (9) is hooked onto the stay (8), the chute pipe (3) will be suspended from the ring (6) by the stay (8). In this case, since there is a gap (b) between the chute pipe (3) and the ring (6), the chute pipe (3) is at a considerably large angle with respect to the ring (6) as shown by the broken line in Figure 4. You can lean up to. Further, a neck flange (b) is slidably fitted into the lower end of the shoot nozzle (eve (3)).

The neck 7 lunge has a sleeve part a that has a larger diameter than the 7 lunge part (b) and the chute pipe (3) that protrudes from the 7 lunge part.
It consists of

In this way, shoot the eve (3) and T-ring (6).
) [When temporarily fixed, neck 7 lunge (2
) to the flange (2) provided at the upper end of the receiving/inlet pipe (2) using bolts or other appropriate means, the chute pipe (3) will attach the upper and lower ends to the ring (6).
) and the neck flange of ) are supported and mounted on the sleeve part α → of ) to connect the dispensing chute (1) and the receiving pipe (2). Finally, ring (6) and chute pipe (
3) Complete the installation by welding the gap (b).

If the angle to be adjusted is large and it is difficult for the lower end of the chute pipe to enter the sleeve part (b) of the neck 7 lange (2), a notch α force can be provided in the sleeve part α◆ as shown in Figure 5. good.

As described above, in this invention, the chute pipe (3) is temporarily fixed by suspending the ring (6) K fixed to the flange at the lower end of the temperature discharge chute (1) via the stay (8) and the U bolt (9). Therefore, the ring (6) can be tilted to a considerable degree with respect to the ring (6), and the angle can be easily adjusted. Also, since the connection with the lower receiving pipe (2) is made via the neck flange (2), the length of the chute pipe can be adjusted using the neck 7 lange (
2) because it is performed by the sleeve part a◆, it is different from the conventional 5
Since there is no need to prepare long materials in advance, and there is no need to cut off parts that are not long during assembly on site, the work is extremely easy. Then, in this way, the upper dispensing chute and the lower receiving pipe are temporarily connected with the chute nozzle tube (3), and finally the gap between the ring and the chute nozzle tube (3) is welded to integrate them. Therefore, installation is quick and reliable, and construction on site is extremely easy.
