Groove angle-changeable supporting roller set achieving large inclination angle conveying

Abstract

The invention provides a groove angle-changeable supporting roller set achieving large inclination angle conveying. The groove angle-changeable supporting roller set comprises middle rollers, side rollers, supports, middle support columns, side support columns, strengthening rib plates and fastening parts, the supporting roller sets are arranged in a double-row mode, the rollers which have the included angle smaller than 60 degrees are arranged in the front, and the rollers which have the large included angle of 60 degrees are arranged at the back. The side rollers can be equal or unequal in length. An intermediate roller of an ordinary roller set is designed to be two rollers which have a certain included angle, adhesive tape is subjected to grooving smoothly, the two side rollers are designed to form a 60-degree angle with the horizontal plane, by means of bearing and non-bearing continuous reciprocating opening and closing operation of the adhesive tape which is subjected to grooving on the supporting roller set, the coefficient of friction of the supporting roller set to the adhesive tape is increased, and therefore wrapping force, namely internal friction of the adhesive tape to materials and the internal friction between the materials are also increased; and it is guaranteed that sliding does not exist between the materials and the adhesive tape, and rolling does not exist between the materials. By adopting the groove angle-changeable supporting roller set achieving large inclination angle conveying, the conveying inclination angle of materials is increased; and by means of large inclination angle conveying, a route can be simplified, equipment investment can be reduced, and construction period can be shortened.

Description

technical field [0001] The invention relates to the field of belt conveyors, in particular to a conveying idler set with a variable groove angle and a large inclination angle. Background technique [0002] Belt conveyor is one of the main equipment for conveying bulk materials. It is widely used in metallurgy, mining, coal, port, chemical industry, water conservancy, electric power and many other industries. As an important bearing part of belt conveyor, the trough roller is fully Using the viscoelastic properties of the tape to form grooves to achieve a certain amount of inclination angle transportation, the groove angle of the idler roller of the ordinary belt conveyor is 30-45°, which can no longer meet the requirements of large inclination angle conveying materials. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conveyor roller set with variable groove angle and large inclination angle, considering that th...
