Telescopic belt conveyor

Abstract

The invention discloses a telescopic belt conveyor, which comprises a basic arm, a first telescopic arm, a second telescopic arm, a third telescopic arm, a driving mechanism and a belt transmission mechanism, and the belt transmission mechanism includes: a belt, an electric drum, a first redirection Drum, second reversing drum, third reversing drum and first adjusting drum, fourth reversing drum and second adjusting drum, fifth reversing drum and third adjusting drum, sixth reversing drum and fourth adjusting drum Drum, the seventh reversing roller; the belt is set on the electric drum, the first reversing roller, the second reversing roller, the third reversing roller, the fourth reversing roller, the fifth reversing roller, the sixth reversing roller and the seventh reversing roller, the first, second, third and fourth adjustment rollers press the belts at the third, fourth, fifth and sixth reversing rollers respectively. The invention has a small height, a small length in a folded state, and a large length in a fully unfolded state, and is suitable for environments with narrow and long spaces and small entrances and exits.

Description

technical field [0001] The invention relates to a telescopic belt conveyor, in particular to a telescopic belt conveyor used in a long and narrow space with limited inlet and outlet dimensions. Background technique [0002] The telescopic belt conveyor has the advantages of high efficiency and labor saving for loading and unloading goods, so it is quite popular. For the narrow and long space with limited entrance and exit dimensions like boxcars, when the telescopic belt conveyor with cantilever beam structure is used to load and unload goods, there are high requirements for the size of the belt conveyor in the folded and unfolded state. In the folded state, if the height of the belt conveyor is too high and the length is too long, it will not be possible to enter the door and cannot change the direction in the compartment; in the unfolded state, the belt conveyor needs to have a longer length so that the belt conveyor can reach the end of the compartment In order to realiz...

AI Technical Summary

Problems solved by technology

In the folded state, if the height of the belt conveyor is too high and the length is too long, it will not be possible to enter the door and cannot change the direction in the compartment; in the unfolded state, the belt conveyor needs to have a longer length so that the belt conveyor can reach the end of the compartment To realize loading and unloading operations in all spatial positions

The general four-section telescopic belt conveyor can meet the requirements in terms of length, but this kind of four-section telescopic belt conveyor needs to be equipped with 7 reversing rollers, resulting in the height of the belt conveyor being too high to meet the requirements

The general three-section telescopic belt conveyor can meet the requirements in terms of height, but its length in the folded state or the length in the fully expanded state cannot meet the requirements.
