Description

Freely-lifting belt conveyor

Technical Field

The utility model relates to the technical field of material conveying, in particular to a free lifting belt conveyor.

Background

In an automated production line, port or dock, a belt conveyor is often used to transport bulk or box-like goods, and the transport height is generally adjusted according to the situation on site, or horizontal transport can be inclined. The prior belt conveyor is driven by a motor which drives a conveyor belt through a roller, wherein the motor is generally arranged at one end. The lifting structure of the conveyor and the conveyor frame body form a triangular structure, the lifting structure consists of two supporting beams, one supporting beam only does rotary motion, and the other supporting beam can do linear motion and can also do rotation. One fixed supporting beam is hinged with the conveying rack, the other supporting beam is connected with the belt conveyor rack in a floating mode, the lower ends of the two supporting beams are hinged with a spindle, and the spindle is supported by the two tires. The floating end is strongly indexed by a steel wire, the other end of the steel wire rope is wound on the rope wheel, and the lifting height is adjusted by adjusting the length of the steel wire rope during lifting.

However, although the existing liftable belt conveyor technology enables the belt conveyor to have a simpler structure, the working process stability of the belt conveyor is poorer, and when the belt conveyor is lifted, the lifting height is adjusted by adjusting the length of a steel wire rope, so that the automation degree is lower, and the labor intensity of operators is high. When the conveying device is conveyed horizontally, only one horizontal height exists, the horizontal lifting range is limited, and when the conveying device is conveyed obliquely, the height of one end is determined, and the height of the other end is only unique; when the belt conveyor runs in the reverse direction, the tight edge is in the return segment, and the slipping phenomenon often appears, so that the belt conveyor only has one conveying direction, and when the belt conveyor needs to convey in the reverse direction, the belt conveyor is often realized by changing the position of the conveyor. In addition, the moving device does not have a steering function, and the belt conveyor can only move along one direction. In summary, a belt conveyor with adjustable height, capability of reversely conveying goods and a steering function is to be invented.
