Novel radian-controllable carrier roller

Abstract

The invention discloses a novel radian-controllable carrier roller used on a belt conveyor for conveying bulk materials. The novel radian-controllable carrier roller is composed of a carrier roller with an embossed surface, flexible wear-resistant sleeving elements capable of sleeving the carrier roller and easy to assemble and detach, and detachable movable baffles and fastening staple bolts which are arranged at the two ends of the carrier roller. According to the invention, the phenomenon that the bulk materials are liable to fall off from a belt, and the potential safety hazards generated due to that a metal steel wire in the belt is exposed and forms friction with the carrier roller after the belt is broken, are solved; the roller diameter of the carrier roller is effectively reduced; the production and maintenance costs are saved; the service lives of the carrier roller and the belt are prolonged; the shortage of a small contact surface of the original carrier roller is overcome, the transmission efficiency is improved; and meanwhile, the possible phenomenon of slip due to contact between metal and the belt of the conveyor is also improved.

Description

technical field [0001] The invention relates to a novel radian-controllable supporting roller of a belt conveyor, which can be widely used in conveying bulk materials in mines, coal mines, docks, warehouses, factories, construction sites and other places. Background technique [0002] At present, as a modern conveying equipment, the belt conveyor has been widely promoted and used because of its excellent performance and the ability to transport various materials over long distances. [0003] As an important part of the belt conveyor, the idler roller is the power transmitter of the belt conveyor and carries very important functions and functions on the belt conveyor. [0004] Such as figure 1 As shown: Most of the existing rollers are in the shape of a cylinder. The disadvantages of this roller group are: the cylindrical rollers cannot bend the belt, and the bulk materials on the belt are easy to fall from the belt; The diameter of the machine idler is large, and the manuf...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown: Most of the existing rollers are in the shape of a cylinder. The disadvantages of this roller group are: the cylindrical rollers cannot bend the belt, and the bulk materials on the belt are easy to fall from the belt; The diameter of the machine idler is large, and the manufacturing cost is high; most of the idler is made of stainless steel, which is easy to wear the belt and reduce the service life of the belt when it is in contact with the belt for a long time; the contact area between the idler and the belt is small. The force is uneven, which reduces the service life of the rollers. At the same time, there may be slippage when transporting more or heavier goods, which affects the transmission efficiency; the friction between the rollers and the belt in long-term use may cause the belt to break. Metal steel wires (to increase the strength of the belt conveyor, steel wires and other metals are laid in the belt) are exposed and rub against the idler rollers, generating sparks and causing safety hazards
