Background

The monorail conveyor has the advantages of small volume, low erection cost and high conveying efficiency, is more and more advocated by people, and is widely used for replacing manual labor in orchard transportation in hilly and mountainous regions. The monorail conveyor is divided into a power drive part and a load carriage part, the load carriage is arranged on a travelling mechanism, the travelling mechanism is arranged on a monorail and is driven by the power of the front part to pull, and the whole monorail conveyor moves forwards along the monorail to finish the transportation. The existing running mechanism is shown in figure 3 and comprises a plate frame body, a loading wheel arranged on the upper portion of the plate frame body and a guide wheel arranged on the lower portion of the plate frame body, wherein the guide wheel is arranged below the single rail, two side faces of the single rail are clamped by limiting portions on two sides of the guide wheel, blank pressing portions on two sides of the guide wheel are attached to the bottom face of the single rail, and the purpose of preventing the running mechanism from side turning is achieved by clamping the loading wheel on the upper portion and the guide wheel on the lower portion. In practical application, the load in a load compartment is difficult to balance, the limit parts at two sides of the guide wheel are different from the impact force of the single rail, because one single side of the rotating shaft through which the guide wheel passes is directly installed in the through hole on the plate frame body in a cantilever manner, the rotating shaft of the guide wheel impacts the installation hole of the plate frame body, when the load is heavier than the side of the installation hole, the rotating shaft is warped downwards, when the load is heavier than the other side, the rotating shaft is warped upwards, and the impact can be intensified at the turning position of the single rail; in addition, because environmental factor such as difference in temperature humidity, the face can't avoid to have deformation about the single track, the distance of single track top surface and bottom surface is in case changed, also can lead to the pivot of leading wheel to strike to the board support body mounting hole, this two kinds of factors merge and lead to the fact that current running gear live time is one long, the combination of leading wheel and board support body is not hard up easily, leading wheel and single track lower part laminating degree reduce, the load carriage rocks in service appear, should rock and can further aggravate the pivot to the impact of mounting hole, finally lead to the unable work of leading wheel, can only change running gear, running gear's life has been shortened.
