A cylindrical conveying corridor bridge

Abstract

The invention discloses a cylindrical conveying gallery bridge. The cylindrical conveying gallery bridge is composed of one or more gallery bridge units; each gallery bridge unit comprises an outer cylinder, a framework structure, an outer stiffening plate, an inner stiffening plate, a support and a carrier roller mechanism, wherein the outer cylinder is a round or oval cylinder, the framework structure comprises an inner framework and a combined jig frame, the inner framework comprises beams which are axially distributed along the inner face of the outer cylinder, the combined jig frame is a rectangular frame composed of two connecting rods, an upper steel beam and a lower steel beam, an inner framework support is arranged at the right corner position composed of each connecting rod and the upper steel beam, the outer stiffening plate is a ring plate connected to the inner framework and the outer face of the outer cylinder, the inner stiffening plate is a ring plate fixedly connected with the inner framework and the inner face of the outer cylinder, the support is a support along with the circle with the outer cylinder, the outer cylinder support is fixed to a foundation, and the carrier roller mechanism is fixed to the combined jig frame and arranged in the outer cylinder. Every two adjacent gallery bridge units of the conveying gallery bridge are connected through splice bolts in splice bolt holes in the outer stiffening plate. The cylindrical conveying gallery bridge has the beneficial effects of being small in self weight of the structure, high in bearing force, economical and convenient to machine and mount.

Description

technical field [0001] The invention belongs to the field of logistics conveying machinery, in particular to a corridor bridge for conveying industrial materials. Background technique [0002] In large-scale projects such as ports, coal mines, grain depots, and power plants, many bulk granular materials need to be transported through large belt conveyors. When there are requirements for material transportation such as windproof, rainproof, moisture-proof, and dust-proof, there are existing technologies that will The conveying machinery is placed in the closed conveying bridge for conveying. The section of the conveying gallery bridge in the prior art is mostly rectangular, and plane trusses or space trusses are used to bear the load. The disadvantage is that the structure is relatively complicated and the weight is relatively large. [0003] With the development of industrial construction technology and computing technology, space structure technology has entered the field ...
