Technical Field
The invention relates to the technical field of belt conveyors, in particular to a belt conveyor with a reversible aligning upper carrier roller group.
Background
The belt conveyor consists of a roller and a conveyer belt sleeved outside the roller, and the conveyer belt is driven by the friction of the roller to circularly move so as to convey materials borne on the surface; the carrier roller is a component for supporting the conveying belt and having rolling friction with the conveying belt.
When the existing belt conveyor is used for conveying, no matter heavy load, light load or no load, all carrier rollers are in contact with a belt, so that the abrasion of the belt and the carrier rollers is undoubtedly accelerated, and particularly when the carrier rollers break down due to the following reasons, firstly, the rigidity of a bearing seat is insufficient, the assembly precision of the carrier rollers is difficult to ensure, and the operation flexibility of the carrier rollers is restricted; secondly, the shell of the carrier roller is blocked by the material; thirdly, the problem of sealing and lubricating; the belt is difficult to drive the carrier roller to rotate, so that sliding friction is formed between the belt and the carrier roller, the abrasion speed of the belt and the carrier roller is greatly accelerated, in the whole belt conveyor, the carrier roller accounts for about 35% of the total cost, the belt accounts for about 20% of the total cost, and therefore the use cost is greatly increased due to the damage of the carrier roller and the belt. Based on this, how to reduce the wearing and tearing between belt and the bearing roller in the belt feeder use is the difficult problem of working on in the trade and solving always, but the development is very little. Based on the technical problem, the invention provides a belt conveyor with a reversible aligning upper carrier roller group, which has small running resistance and small abrasion between a belt and carrier rollers.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A method of reducing running resistance of a belt conveyor, comprising: dividing the upper carrier rollers into a plurality of groups, wherein each group comprises the same number of upper carrier rollers, the upper carrier rollers of each group are sequentially arranged in an inserting manner along the length direction of the conveying belt, and the number of the groups of the upper carrier rollers contacting with the belt is adjusted according to the actual carrying capacity of the conveyor;
assuming that the upper carrier rollers are divided into n groups, the maximum carrying capacity is m, the carrying capacity of the belt is divided into n stages corresponding to the number of the upper carrier roller groups, several upper carrier roller groups are required to be in contact with the belt in the stage of several times, if the carrying capacity x is a stage every time, x is m/n, and the carrying range of the stage s is: (s-1). x to s.m, detecting the actual carrying capacity of the belt, judging which stage the belt is in, and then adjusting the number of groups of upper carrier rollers which are in contact with the belt and correspond to the stage;
by the adjusting method, a reasonable number of upper carrier rollers are in contact with the belt according to the actual carrying capacity of the belt, so that the supporting effect of the upper carrier rollers on the belt is ensured, and the normal conveying of the belt is ensured; on the other hand, all the upper carrier rollers are not required to be in contact with the belt, so that the friction loss between the belt and the upper carrier rollers is reduced, the service life of equipment is prolonged, the running resistance of the belt is reduced, and the energy consumption is reduced;
the number of the upper carrier rollers is specifically designed into a plurality of groups, and is determined according to acceptable manufacturing cost, the number of the minimum carrier rollers required in an unloaded state and the number of the minimum carrier rollers required in a fully loaded state, and no matter how many groups are divided, the principle of reducing the number of the upper carrier rollers contacted with the belt as far as possible is adopted as long as the normal conveying state of the belt is ensured.
