Traction mechanism for pipeline conveying apparatus and pipeline conveying apparatus comprising the same
A traction mechanism for pipeline conveying apparatus comprises a flat belt and a plurality of trays fixedly arranged in the lengthwise direction at intervals on the flat belt. The pipeline conveying apparatus further comprises a pipeline, where the traction mechanism is arranged in the pipeline in a penetrating manner, and the pipeline conveying apparatus is further provided with a driving mechanism for driving the traction mechanism to move in the pipeline.
1. A traction mechanism for a pipeline conveying apparatus, comprising
a flat belt, and
a plurality of trays,
wherein the plurality of trays are fixedly arranged in a lengthwise direction of the flat belt at intervals, each of the trays comprises a notch for receiving a driving portion of a driving mechanism that engages with each of the trays, a width of the notch is greater than a width of the flat belt, and the flat belt is embedded and fixed in the notch; and
the flat belt is annular and adopted to be driven by rotating at least one driving wheel to move in a pipeline by wheel surface friction of the driving wheel.
2. The traction mechanism of claim 1 , wherein the flat belt is made of stainless steel, and has a thickness of 0.1 mm to 1.0 mm and a width of 1 mm to 100 mm.
3. The traction mechanism of claim 1 , wherein the flat belt is made of resin, and has a thickness of 0.1 mm to 3.0 mm and a width of 1 mm to 100 mm.
4. The traction mechanism of claim 3 , wherein the resin flat belt comprises a reinforcing core wire.
5. The traction mechanism of claim 4 , wherein the reinforcing core wire is made of stainless steel.
6. The traction mechanism of claim 1 , wherein the flat belt is provided with protrusions or holes for fixing the trays.
7. A pipeline conveying apparatus, comprising
the traction mechanism as described in claim 1 ,
the driving mechanism, and
the pipeline,
wherein the traction mechanism is arranged in the pipeline in a penetrating manner, and the driving mechanism drives the traction mechanism to move in the pipeline.
8. The pipeline conveying apparatus of claim 7 , wherein the driving mechanism comprises at least one driving wheel arranged on the flat belt in a sleeving manner for driving the flat belt to move in the pipeline by friction force, and the driving wheel rotates to drive the flat belt to move in the pipeline by wheel surface friction of the driving wheel.
9. The pipeline conveying apparatus of claim 8 , further comprising
a tensioning wheel arranged on the flat belt in a sleeving manner.
10. The pipeline conveying apparatus of claim 8 , further comprising
a steering wheel arranged on the flat belt.
11. The pipeline conveying apparatus of claim 8 , further comprising
a cleaning scraper,
wherein the cleaning scraper is arranged above an attaching surface of the flat belt and the driving wheel.
