Description

Track tubular belt conveyor with locking vehicle

Technical Field

The invention relates to the technical field of belt conveyors, in particular to a track tubular belt conveyor with a locking vehicle.

Background

The tubular belt conveyor has the advantages of flexible circuit arrangement, closed material conveying and reduced environmental pollution along the line. The traditional tubular belt conveyor consists of six or eight rollers to form a polygonal window type carrier roller, and the surrounding conveying belt is shaped like a circular tube, so that the conveying of materials in a pipeline is realized. Because of the transverse elastic action of the conveying belt, the diameter of a circular pipe which is presented by the conveying belt between the two groups of window type carrier rollers is larger than the diameter of the window type carrier rollers, and each group of window type carrier rollers can generate additional extrusion on the circular pipe of the conveying belt in operation, so that the conveying belt has large running resistance, high strength, high power loss and limited conveying distance. The window type carrier roller has no effective circumferential restraint means on the conveying belt, and the phenomenon of deviation and torsion of the tubular conveying belt can also occur frequently so as to influence the normal operation.

In recent years, rail-mounted tubular belt conveyors have been developed in which window-type idler rollers are replaced with rail cars to reduce running resistance. For example: 1. the carrier roller is used for supporting the conveying belt, and the carrier roller still needs to press the conveying belt from above to keep the circular tube shape because the carrier roller cannot encircle the conveying belt. The carrier roller of the technology walks along with the conveyer belt, and the position of the upper carrier roller is fixed. The carrier roller and the upper carrier roller are not on the same section most of the time, which is not beneficial to the requirement of encircling the conveyer belt into round tubes; 2. the carrier band car is adopted to support the conveying belt, the belt pressing car is arranged above the conveying belt, and the conveying belt is surrounded to form a circular tube shape under the combined action of the carrier band car and the belt pressing car. The mode can keep the carrier belt car and the belt pressing car at the same position, and has a better pipe forming effect of encircling the conveying belt. However, the carrier belt car and the belt pressing car need to run on respective tracks, and the complexity of the structure is increased. 3. The conveyor belt is surrounded by a movable bracket arranged in the closed frame to form a circular tube shape. The movable bracket runs on the rails arranged in the closed frame, and the closed and opened conveyer belt is realized through the restraint and the guide of a plurality of rails, so that the structure is very complex, and the equipment maintenance is inconvenient. Based on the design, the track tubular belt conveyor with the locking vehicle provides a bulk cargo conveying mode which not only plays the energy-saving and environment-friendly advantages of the track tubular belt conveyor, but also is simpler and more effective to restrict the conveying belt to be in a circular tube shape.
