Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a double-belt bidirectional belt conveyor. Background Art

[0002] Domestic tubular belt conveyors are developing rapidly, and their application in power plants is increasing. In recent years, there are fewer new power plants and more expansion projects, and the demand for communication between multiple coal yards is becoming more and more vigorous. Tubular belt conveyors have the advantages of large-angle turning, two-way transportation, and small footprint, which are very suitable for the application scenario of multiple coal yards.

[0003] At present, there is no mature case of bidirectional tubular belt conveyor for material transportation between two material points in domestic power plants. Under the design requirements of short-distance, double-belt bidirectional transportation, it is urgent to solve the layout problem:

[0004] 1. The middle design of the trestle of a short-distance double-belt bidirectional tubular belt conveyor generally requires the four belts on the outbound and return journeys to be horizontally spread out, with a width of about 10m.

[0005] 2. Due to the expansion in the middle, the front and rear trestles and pipe-belt conveyors need to be arranged in curves at a larger angle, which makes the design more difficult.

[0006] 3. The entire belt conveyor has many curved parts and bends back and forth in a short distance. Some rollers are easily overloaded and damaged, and the belt conveyor is prone to deviation and twisting.

[0007] 4. The overall layout of the guard belt conveyor is irregular, narrow at both ends and wide in the middle, the trestle investment is large and the appearance effect is not good. Summary of the invention

[0008] In view of the above-mentioned technical problems, the present invention provides a double-belt bidirectional pipe belt machine to solve the problem that the existing double-belt bidirectional tubular belt conveyor has a wide lateral expansion in the middle part and is difficult to arrange within a short distance. The double-belt bidirectional pipe belt machine reduces the arrangement spacing of the four parallel pipe belts, thereby achieving the purpose of saving space and investment and optimizing the appearance.

[0009] The present invention discloses a double-belt bidirectional tube belt machine, comprising a first bidirectional tube belt machine and a second bidirectional tube belt machine, wherein the first bidirectional tube belt machine comprises a first upper tube and a first lower tube, the first upper tube and the first lower tube are arranged in an X-shaped cross-arrangement, and two ends of the first upper tube and two ends of the first lower tube are located in the same vertical plane, the first upper tube and the first lower tube have a first intersection point, and the first upper tube is provided with a first arc segment for avoiding the first lower tube at the position of the first intersection, and the second bidirectional tube belt machine comprises a second upper tube and a second lower tube, the second upper tube and the second lower tube are arranged in an X-shaped cross-arrangement, Both ends of the second upper tube and both ends of the second lower tube are located in another vertical plane, the second upper tube and the second lower tube have a second intersection, the second upper tube is provided with a second arc segment for avoiding the second lower tube at the position of the second intersection, the first lower tube and the second lower tube are parallel to each other, the first upper tube and the second upper tube are located between the first lower tube and the second lower tube, the first intersection and the second intersection are located at different heights, the projections of the first arc segment and the second arc segment in the vertical direction have an overlapping part, and the first arc segment avoids the second arc segment.

[0010] Further, the first bidirectional belt conveyor includes a first belt turning mechanism and a second belt turning mechanism, the first belt turning mechanism is located between one end of the first upper tube and one end of the first lower tube, the second belt turning mechanism is located between the other end of the first upper tube and the other end of the first lower tube, and the second bidirectional belt conveyor includes a third belt turning mechanism and a fourth belt turning mechanism, the third belt turning mechanism is located between one end of the second upper tube and one end of the second lower tube, and the fourth belt turning mechanism is located between the other end of the second upper tube and the other end of the second lower tube.

[0011] Furthermore, a first walkway is disposed on an inner side of the first upper tube, a second walkway is disposed on an inner side of the first lower tube, and the first walkway and the second walkway have a common portion at the first intersection.

[0012] Furthermore, a third walkway is disposed on the inner side of the second upper tube, a fourth walkway is disposed on the inner side of the second lower tube, and the third walkway and the fourth walkway have a common portion at the second intersection.

[0013] This double-belt bidirectional pipe conveyor is mainly a system solution for the middle layout of the belt conveyor when two parallel tubular belt conveyors realize bidirectional transportation between two material points. Among them, the first lower tube and the second lower tube are always arranged from the lower left to the upper right in a vertical plane, and there is no space bend. The first upper tube and the second upper tube are constantly approaching the inside from left to right and staggered, forming an upper and lower overlapping arrangement at the first intersection and the second intersection, and then separated to the same vertical plane of the first lower tube and the second lower tube, effectively reducing the horizontal expansion width of the middle part, thereby reducing the bending curvature of the belt within a short distance and reducing the consumption of the trestle steel structure. The optimized finite element analysis shows that the force on the pipeline machine frame is also relatively uniform, and it can still meet the actual operation needs well. In addition, the width of the trestle is reduced after optimization, the consumption of the trestle steel structure is reduced, and the initial investment cost is reduced.
