Description

Rotating assembly of telescopic conveyor and telescopic conveyor

Technical Field

The utility model provides a rotating assembly and telescopic conveyor of telescopic conveyor relates to the commodity circulation conveyer field.

Background

The common telescopic conveyor is a belt conveyor, and is used as common equipment for conveying materials remotely, which is important in engineering application. As shown in fig. 1 and 2, a belt rotating mechanism of a telescopic conveyor in the prior art generally comprises a roller 1 and a conveying belt 2, and the conveying belt 2 is driven to rotate by virtue of friction force between the surface of the roller 1 and the surface of the conveying belt 2, so as to achieve the purpose of conveying materials. However, this construction has some problems, firstly, the belt conveyor is used frequently and has a long running time, so that the reliability of the belt conveyor is also required. The existing belt conveyor can loose and deform due to the loading and self reasons after running for a period of time, and the situation of loosening is easy to occur when the belt is longer, which is particularly obvious on a telescopic conveyor; secondly, how to increase the friction between the belt and the roller, the prior art drives the belt to rotate by the friction between the driving roller and the surface of the belt, so that the requirement on the driving of the conveyor is high, and particularly in a telescopic conveyor, because the length of the belt is increased due to the extension of a conveying line, the belt needs to be tensioned, and the belt needs to be driven by a larger friction between the belt and the roller, so that the larger the roller is, the higher the strength requirement of a rack material is, and the larger the driving requirement is, and the larger the energy consumption is; thirdly, the existing belt conveyor can generate the deviation phenomenon when the belt rotates on the roller.

Chinese patent application publication (publication No. CN 109292367a) discloses a novel belt conveyor, which solves the technical problem of belt slack, i.e. a plurality of support plates are arranged in a conveyor frame, the support plates are located between the conveyor belts, the upper end surfaces of the support plates are parallel to the conveyor belts, the problem of belt slack is solved by the support action of the support plates, and a belt slack adjuster is also provided, but this technical scheme cannot solve the problem of belt slack caused by too long dead weight of the belt in long-distance transportation.

The Chinese utility model patent specification (grant publication number: CN204938089U) discloses a novel telescopic belt conveyor. The tension pulley is arranged between the chain wheel and the tail end roller, but the belt has large mass due to long conveying distance, the requirements on the strength of the tension pulley and the conveyor frame are large, the structure of the conveyor is relatively complex for keeping the stable performance of the conveyor, and the conveyor is large in size, large in mass and inconvenient to move due to the fact that the conveyor is generally made of thick steel plates due to large material strength of the conveyor.

In reality, in order to increase the friction force between the belt and the roller, the belt used in the existing telescopic conveyor adopts impregnated three-dimensional industrial cloth on the surface contacting with the roller, but the friction force is increased, the mass of the belt is also greatly increased, and the requirement on the belt tensioning wheel is correspondingly increased.

The prior art also provides a technical proposal for solving the problem of the off tracking of the belt, the roller body is arranged to comprise a plane roller section positioned in the middle and conical roller sections positioned at two sides of the plane roller section, after a roller with a certain inclination at the middle flat two sides is adopted, when the belt is matched, the middle part is in a tension state with the belt due to higher height, and the parts at the two sides have certain inclination, therefore, the belt is in contact with the belt but is not in a tension state, when the force on one side of the belt is uneven, because the belt in the middle is in a tension state, therefore, certain counterforce is exerted on two sides, the two sides are in a non-tensioning state, and the two side parts have certain elasticity, so that the elastic force-adjustable plastic pipe has certain self-deformation adjusting capacity, therefore, the reaction force can offset the deformation, thereby avoiding the continuous deviation towards one side after being stressed due to the same belt tension at all positions on the roller.

Although the prior art seems to solve the problems of belt looseness, deviation and the like, the strength of the manufacturing material of the conveying machine is infinitely enhanced, particularly the thickness of the steel plate of the rack and the power of the driving motor are increased, and a simple and economical solution cannot be obtained.
