Description

Technical Field

[0001] The utility model relates to the technical field of a fast-assembled split truss for a belt conveyor, in particular to a fast-assembled split truss for an overhead belt conveyor. Background Art

[0002] The truss on the belt conveyor is used to carry loads such as rollers, belts, materials, and inspectors, and is the main structure of the overhead belt conveyor. The belt conveyor corridor can be divided into: trestle structure, bracket structure, integrated truss structure, etc.

[0003] As far as the current trestle structure is concerned, it is necessary to arrange the supporting legs and middle frames of the rollers inside the trestle. The installation workload is large, more materials are used, and it is not economical. Bracket structure: The walkway, legs and middle frame are installed on the upper plane of the bracket, which occupies a large space and is difficult to install. Integrated truss structure: The roller tape is installed on the window frame of the truss, eliminating the legs and middle frame. The walkway is installed on both sides of the truss, which occupies a small space and is easy to install, but the transportation cost is high. Based on this, a quick-assembly split truss for an overhead belt conveyor is designed to solve the existing technical and economic problems such as large space occupation, difficult installation, and high transportation costs. It is particularly suitable for export projects and can greatly reduce land and sea transportation costs. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a quick-assembly split truss for an overhead belt conveyor, which effectively solves the limitations of over-width and over-height during transportation. Since the truss can be disassembled for operation, the total volume is greatly reduced, the packaging cost is reduced, and more importantly, the land and sea transportation costs are significantly reduced.

[0005] The purpose of the utility model is achieved through the following technical solutions: a quick-assembly split truss for an overhead belt conveyor, which is used to carry loads such as rollers, tapes, materials, and inspection personnel, and is the main structure of the overhead belt conveyor. The quick-assembly split truss includes a truss body, and the truss body includes an upper single piece, a lower single piece, an upper roller and a lower roller. The upper single piece is connected to the lower single piece by several window frames, and vertical and oblique rods are arranged between adjacent window frames. The upper rollers and lower rollers are both connected to the window frames, and tapes are arranged on the tops of the upper rollers and lower rollers. The tapes are the traction components of the belt conveyor and the components that carry materials.

[0006] The upper single piece includes two upper chords and several upper oblique rods, and the two upper chords are connected and fixed by several upper oblique rods. The lower single piece includes two lower chords and several lower oblique rods, and the two lower chords are connected and fixed by several lower oblique rods. Positioning plates are provided at the bottom of the upper single piece and the top of the lower single piece.

[0007] The positioning plate includes a window frame positioning plate and a vertical diagonal rod positioning plate. Several window frames are evenly distributed between the upper single piece and the lower single piece, and are fixed to the upper chord rod and the lower chord rod respectively through the window frame positioning plate. The vertical diagonal rod is fixed to the upper chord rod and the lower chord rod respectively through the vertical diagonal rod positioning plate.

[0008] The upper oblique rods respectively form an angle of 45 degrees with the two upper chord rods, and adjacent upper oblique rods form an angle of 90 degrees. The lower oblique rods respectively form an angle of 45 degrees with the two lower chord rods, and adjacent lower oblique rods form an angle of 90 degrees.

[0009] The window frame is composed of two cross bars, a middle cross bar and two vertical bars to form a sun-shaped structure. The upper roller is arranged on the top of the middle cross bar and fixedly connected to the vertical bars. The lower roller is arranged below the middle cross bar and fixedly connected to the vertical bars.

[0010] Walkways for inspection personnel to pass through are arranged on both sides of the left and right sides of the truss body, and a crossbeam for supporting the walkway and the truss body is arranged at the bottom of the truss body, and a railing is arranged on the outside of the walkway, and the railing is connected to the crossbeam.

[0011] The crossbeam is made of section steel and steel plate by resistance welding, and the walkway is made of patterned steel plate folded edge, which reduces the amount of welding and increases the rigidity of the walkway.

[0012] The railing comprises a plurality of uprights, a plurality of steel pipes and a connecting plate. The steel pipes and the uprights are interlaced and fixedly connected with each other, and are fixed with the cross beams through the connecting plate.

[0013] The handrail and the crossbeam, the upper roller and the window frame, and the lower roller and the window frame are all fixedly connected by bolts, and are easy to install.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model effectively solves the limitations of over-width and over-height during transportation. Since the truss can be disassembled for operation, the total volume is greatly reduced, the packaging cost is reduced, and more importantly, the land and sea transportation costs are significantly reduced.

[0016] 2. The utility model only needs to make simple tooling to produce upper single pieces, vertical and oblique rods, window frames, lower single pieces, beams, walkways and railings in batches, and can realize modular production. During the installation process, bolt connections are used, which greatly reduces labor intensity. While ensuring product accuracy, it effectively protects the product appearance quality and saves production, transportation and installation costs. BRIEF DESCRIPTION OF THE DRAWINGS
