Description
Technical Field
The invention relates to the field of belt type material conveying machinery, in particular to a pressing steering device of a belt type conveyor.
Background
The belt conveyor is a common material conveying device and is widely applied to various industries such as metallurgy, mines, coal, ports, electric power, building materials, chemical engineering and the like, the belt conveyor mostly adopts two modes of direct inclination angle variation and gradual inclination angle variation when the inclination angle changes, and the direct inclination angle variation mostly adopts a single-shaft press belt roller or a plurality of single-shaft press belt rollers to press the whole belt inclination angle variation; the gradual change angle depends on the dead weight of the conveyer belt, the diameter of the gradual change angle is enlarged to enable the conveyer belt to naturally fall on the lower carrier roller, and the change of the conveying inclination angle of the conveyer belt can be completed without increasing the pressure belt roller.
Because the gradual change inclination angle of the conveyor needs to adopt a large-radius radian to meet the requirement of natural falling of the conveyor belt, the length of the gradual change inclination angle conveyor is much longer than that of a direct angle change conveyor, and the longer the inclination angle change is, the longer the length of the conveyor is. The cost of the conveyor equipment is increased, meanwhile, the gradual change inclination angle conveyor is used for the loose part of the space structure due to the fact that the conveyor occupies a large space, the space structure is compact, the length of the part is limited, and a straight change inclination angle conveying mode is mostly adopted for the belt conveyor with the limited space structure.
The single-shaft belt pressing roller steering device is one of important parts of a belt conveyor, and has the main functions of preventing the rubber belt of a conveying belt at a turning part from being lifted and separated from a roller surface, namely, the phenomena of material scattering, complicated angle adjusting steps and the like caused by belt floating and belt material running when the belt conveyor is started in a no-load mode. The existing single-shaft belt pressing roller device at home and abroad is characterized in that two pressing wheels are connected on a cross shaft, and two rollers respectively press a belt edge of a belt to convey materials. The device has a plurality of disadvantages, one is that when the conveyer belt conveys large materials, the conveyer belt is easily blocked by the pinch roller shaft, so that the large materials cannot pass through the conveyer belt, and the phenomena of blanking and scattering are generated; secondly, because the contact surface of the belt pressing roller and the conveying belt is extremely small, under the condition that the belt is tensioned, the tension on two sides of the belt is far greater than that on other parts, the outer edges of two sides of the conveying belt are easy to tear, and the service cycle of the conveying belt is shortened; and thirdly, because of the pressing of the belt roller and the friction of the conveyer belt, the edge of the conveyer belt is seriously abraded, the service cycle of the conveyer belt is shortened, and the operation cost of the conveyer is increased.
