2. The pipeline produces horizontal force in the rolling process, and the material shelf is easy to turn on one's side by impacting the guardrail of the material shelf.

3. The pipeline rolling position has randomness, which is not beneficial to the orderly stacking of the pipeline on the material rack.

Disclosure of Invention

The invention aims to provide a pipeline discharging device, so that pipeline damage is reduced, a material rack is prevented from being turned on one side, and pipelines are stacked in order.

In order to achieve the purpose, the invention adopts the following technical scheme: pipeline discharge apparatus, which comprises a supporting rack, be equipped with the support groove on the support frame, climbing mechanism, the stand, blanking mechanism, climbing mechanism includes one-level unloading strip, one-level unloading strip goes up and down to pass the support groove, the interval of one-level unloading strip and stand is less than the pipeline diameter, the stand upper end is equipped with second grade unloading strip, one-level unloading strip and second grade unloading strip upper surface slope set up, blanking mechanism is close to material frame one side and is equipped with tertiary unloading strip, one-level unloading strip, second grade unloading strip, tertiary unloading strip respectively has two, two one-level unloading strips, two second grade unloading strips, horizontal interval between two tertiary unloading strips scales up in proper order.

After the pipeline is produced and is accomplished, be carried on supporting the groove, the ascending support groove that passes of one-level unloading strip, jack-up the pipeline, when the pipeline height was higher than the stand, the pipeline was rolled down along the second grade unloading strip continuously, and then falls on tertiary unloading strip, and the guardrail of material frame is spacing to the pipeline, and when the pipeline stack height on tertiary unloading strip was close guardrail top height, blanking mechanism drove tertiary unloading strip and descends, repeats the above-mentioned process, fills up the material frame until the pipeline. The beneficial effect of this scheme does:

1. the impact force of the multistage discharging strip during rolling of the pipeline is buffered, and further damage to the pipeline is reduced.

2. The larger the horizontal distance between each stage of discharging strips is, the larger the sinking amplitude of the middle of the pipeline is, the inclination of the contact surface of the pipeline and each stage of discharging strips can be generated, so that the gravity of the pipeline generates a horizontal component force vertical to the rolling direction of the pipeline, and the horizontal component force further generates a sliding friction force to reduce the speed of the pipeline. The pipeline is jacked up by the primary discharging strip, and the inclined upper surface of the primary discharging strip enables the pipeline to generate a downward initial speed; the horizontal distance between the secondary discharging strips is increased, and the first speed reduction is carried out on the pipeline; and the horizontal distance between the three-stage discharging strips is continuously increased, and the speed of the pipeline is reduced for the second time, so that the pipeline is finally stopped on the three-stage discharging strips. The material shelf is prevented from side turning over by reducing the impact of the pipeline on the guardrail.
