Description
Technical Field
The invention relates to a stay-cord type longitudinal positioning device for a hanging return roller of a belt conveyor, in particular to a device for fixing and adjusting the position of the hanging return roller along the central line direction of the belt conveyor.
Background
At present, in order to adapt to poor flatness and unstable geological conditions of a belt conveyor way and meet the requirements of extension and transfer of the belt conveyor, a shifting type or semi-fixed belt conveyor and a hanging carrier roller are used for a mining working surface, a dumping working surface and an end slope conveying system of an open pit mine. In addition, when the geological conditions are special or the application units have special requirements, a belt conveyor with hanging carrier rollers is also adopted. The belt conveyor selects the hanging carrier roller to ensure that the belt conveyor can still normally run when the rack is slightly distorted due to terrain change.
Since the belt conveyors used today primarily for transporting material from the pit to the ground, the vertical profile of the belt conveyor usually represents an inclined upward or horizontal transport of material. Each hanging return idler (namely a pair of left and right idlers) is arranged on a return traction steel wire rope through a U-shaped bolt, specifically, a connecting clamping plate of the hanging carrier idler between the pair of idlers is arranged in the U-shaped bolt, each U-shaped bolt is arranged on the return traction steel wire rope, namely, the return traction steel wire rope passes through the upper and lower pressing plates of the U-shaped bolt, and then the upper and lower nuts of the U-shaped bolt push the respective pressing plates to move in opposite directions to press the return traction steel wire rope therein. Because the hanging return idler and the middle frame are flexibly connected, and a back inclination angle is naturally formed between the hanging return idler and the return conveyer belt, the return conveyer belt is easy to deviate, and for a belt conveyer with a larger included angle with a horizontal plane, the larger back inclination angle can aggravate the abrasion of the idler and the return conveyer belt and increase the energy consumption.
In order to protect the environment, after an inner discharge space is formed in an open pit, stripped objects and other waste residues need to be refilled into an inner discharge field of the open pit. Because the ground of the inner soil discharge field is relatively soft, only a movable or semi-fixed belt conveyor and a hanging return roller can be adopted. Because the topography of the inner soil discharge field is relatively low, the shifting type or semi-fixed type belt conveyor for the inner soil discharge field generally shows that materials are conveyed downwards in an inclined mode from the longitudinal section of the belt conveyor, a forward inclination angle is naturally formed between the hanging return idler and the return conveyor belt, and for the belt conveyor with a large included angle with the horizontal plane, the large natural forward inclination angle can aggravate the abrasion of the hanging return idler and the return conveyor belt and increase the energy consumption.
