Description

The invention relates to transporting equipment for heat treatment of products transported through a furnace, and can be used: in the oil, ferrous and non-ferrous metallurgical industries.

The aim of the invention is to increase reliability by ensuring uniform distribution of the pulling force between conveyor chains.

FIG. depicts a conveyor for moving the heated products in the furnace; view from above; in fig. 2 shows section A-A in FIG. one; in fig. 3-section BB in FIG. 2; in fig. 4 is a section on BB in FIG. 3

The conveyor consists of four traction chains 1, including high bearing cradles 2 and low bearing cradles 3, driving 4 and driven sprockets of the tensioning device 6, drive 7 and guiding traction chains 8.

The conveyor works as follows.

When the actuator 7 is turned on, the drive sprockets 4, which set the driving chains 1 in motion, begin to rotate. Since the load-bearing cradles 2 have a much greater height than the bed. 3, the heated products, for example, heavy 9, laid on the conveyor rolling lies only on those chains, which in this cross-section of the conveyor belong to high support lodgments 2. Since the height difference between lodgements 2 and 3 can be preselected greater than the possible difference in the levels of the guides under the traction chains, carrier beds

The cops 2 of the heated products 9 will not touch the cradle 3 and load their chains.

The product, located on the next section of the conveyor, rests on the high support cradles 2 two other traction chains, and the traction chains, whose support high cradles were loaded with the preceding slab, are not loaded at this stretch. Thus, with the considered construction of a four-chain conveyor, the products placed on the conveyor along the entire length of the product alternately load one pair of chains and the other, and the weight of the entire load is evenly distributed over all four chains. If there are more than four quantities of traction chains at the conveyor, the weight of the entire load is also evenly distributed over all the conveyor chains.

In comparison with the prototype in the proposed conveyor due to the presence of groups of high support lodgments located along the length of the conveyor with a gap between them, and along the width of the conveyor in pairs on two transversely alternating different traction chains, the heated products are placed on the conveyor

traction chains, then to others.

In this case, the weight of all products placed on the conveyor is evenly distributed to all, without exception, traction chains, which naturally reduces to a minimum the load on each circuit separately, and thereby increases their service life and increases the reliability of the conveyor and furnace in operation.
