The short supporting beam and the long supporting beam can support the stress of the roller chain and guide the sliding direction of the roller chain, the upper ends of the short supporting beam and the long supporting beam are respectively provided with a slide way, the roller chain can be guaranteed to slide flexibly, the abrasion of the chain is effectively reduced, the service life of the chain is prolonged, the slide ways comprise sliding grooves and sliding ribs welded in the middle of the sliding grooves, and the whole slide way is firm and reliable.

The roller length of roller chain is greater than the width of smooth muscle, and roller chain width is less than the distance between the spout internal surface, and the height that highly is less than the spout of smooth muscle can guarantee that the roller of roller chain just in time rides directly over the slide when using, and the chain cylinder freely slides on the smooth muscle of slide during the transmission, and the both ends of roller chain also are located the slide simultaneously, avoid the skew of chain slip in-process slip direction, guarantee the normal use of equipment.

The lower ends of the short supporting beam and the long supporting beam are respectively provided with a slideway, the roller chain rotates around the supporting beam periodically, the lowest end of the supporting beam is provided with the slideway, and the lower end of the chain can slide on the slideway in the rotating process, so that the abrasion of the chain is reduced.

Short supporting beam and long supporting beam are domes, and domes can guarantee better the gravity of bearing tubular product, and when roller chain was used for carrying heavier objects such as tubular product, a supporting beam atress was bigger, especially long distance transport, and the very easy emergence of rectangular shape is cracked, but domes bearing capacity is stronger, and a supporting beam is difficult to the emergence fracture, and the arch is located short supporting beam and long supporting beam's lower extreme simultaneously, is favorable to the chain to carry the heavy object.
