[0002] Circular tube belt conveyor is a key equipment for long-distance bulk material transportation. Its good transportation sealing can effectively prevent the dust from affecting the surrounding environment during bulk material transportation. It also has the advantages of strong turning ability and good adaptability to terrain, which can effectively reduce construction costs. The large-span concave arc layout is a common layout method for circular tube belt conveyors when crossing rivers and hills. At present, a structure in which a pipe belt conveyor is arranged on the upper side of a suspension bridge for large spans is adopted.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1-Figure 37 A circular tube belt conveyor with a flexibly adjustable fuselage comprises a tubular belt 10, a plurality of window units, two towers 9 and a plurality of tensioning adjusters 5 fixed on the ground anchoring foundations on both sides of the river. The tensioning adjuster 5 is an existing device, which can adjust the rope used with it and fix it after adjustment. Here, an example of a common tensioning adjuster 5 is given. The tensioning adjuster 5 comprises a bracket 11, a rope locking block 12, a swing frame 13, a cylinder 14, a pin 15 and a conical sleeve 16. A plurality of brackets 11 are fixedly installed on the ground anchoring foundations on both sides, and a swing frame 13 is rotatably installed on each bracket 11. An oil cylinder 14 is rotatably installed between each bracket 11 through a pin 15, and the telescopic end of the oil cylinder 14 is rotatably connected to one end of the swing frame 13. Matching rope locking blocks 12 are fixedly installed on the bracket 11 and the swing frame 13, and a conical sleeve 16 is also installed on each bracket 11; when in use, the swing frame 13 is pushed and pulled by the oil cylinder 14 to drive the rope locking block 12 to self-lock or relax, so as to achieve the required adjustment. At the same time, before tensioning the rope, the conical sleeve 16 should be loosened first, and the conical sleeve 16 should be tightened after the rope is tensioned in place, so that the rope can be further stably fixed on the bracket 11; the conical sleeve 16 is a conical and hollow structure with a certain elasticity. When relaxed, the rope can pass through the conical sleeve 16 smoothly. When tightening is required, the nut included in it applies axial pressure to the conical sleeve 16, thereby fixing the rope passing through it; the window unit arrangement spacing can be dynamically adjusted according to the requirements of the circular tube belt conveyor.

[0021] Multiple rope reversing frames 8 are installed on both towers 9. Multiple tensioning adjusters 5 located at the top are fixedly installed with multiple installation auxiliary ropes 1 through corresponding rope reversing frames 8. Multiple installation auxiliary ropes 1 are jointly installed with two maintenance vehicles 6. The maintenance vehicles 6 are located on both sides of the window unit and are used for the early installation of the flexible fuselage and the later inspection of the circular tube belt conveyor. The curvature of the installation auxiliary rope 1 is adjusted by the tensioning adjuster 5, and the curvature of multiple installation auxiliary ropes 1 is the same.

[0022] The other multiple tensioning adjusters 5 at the heights are respectively installed with upper ropes 2, middle ropes 3, and lower ropes 4 from top to bottom through the corresponding rope reversing frames 8. The upper ropes 2, middle ropes 3, and lower ropes 4 are respectively fixed to the upper side, middle part, and lower side of the window unit through the rope clamping seats 17. The upper ropes 2, middle ropes 3, and lower ropes 4 are adjusted by the tensioning adjusters 5 to form different concave arc radii, and the auxiliary ropes 1, upper ropes 2, middle ropes 3, and lower ropes 4 are installed to be arranged with the same center of a circle; according to different terrains, the heights of the tower columns 9 at both ends are changed, and the installation of the auxiliary ropes 1, The tensioning adjustment of the upper rope 2, the middle rope 3, and the lower rope 4 can obtain arcs of different radii, so that the radius of the concave arc can be adjusted on site according to the overlapping conditions of the front and rear pipe-belt machines, thereby overcoming the influence of the construction accuracy of civil engineering on the arc installation quality of the fuselage; at the same time, when applied to different pipe-belt machine projects, the tension of the upper rope 2, the middle rope 3, and the lower rope 4 is adjusted according to the different tensions of the tubular tape 10, so that the tension of the tubular tape, the dead weight of the equipment and materials, and the tension of the wire rope form a dynamic balance, effectively reducing the influence of natural wind on the fuselage, thereby achieving stable operation of the pipe-belt machine.

[0023] The specific calculation idea is as follows: first establish a curved fuselage model, calculate the deadweight load, tape and material load of the fuselage. According to the different construction stages, the deadweight load, tape load and material load are decomposed into each window unit, and finally the load is applied to each node of the upper, middle and lower three ropes. The nodes of the ropes can be regarded as hinged tension two-force rods. The two-force rods form a force balance at the nodes. According to the force balance condition, the force of each node is accumulated along each rod to both sides of the rope. Finally, the rope end force at different construction stages is obtained, and the end force is adjusted by the tension regulator 5 to adjust and change the curvature of the flexible fuselage.

After the tubular tape 10 is completely installed, the shaft 25 continues to rotate, so that the roller 19 is reset for use; Step 8: During cleaning, the corresponding roller 19 rotates through the cooperation of the magnetic block 42 and the magnetic block 45, so that the airflow is continuously generated in the cleaning box 32. At this time, the pipe 46 is blocked, and the airflow directly cleans the corresponding roller 19 through the pipe 33; Step 9: Adjustment in windy weather, the servo motor 24 drives the one-way bearing 2 30 to rotate, the one-way bearing 2 30 rotates through the shaft 35 and the movable frame 37 to drive the block 38 to move, the block 38 moves through the rod 39, the blocking block 1 40, and the blocking block 2 41 to block the cleaning box 32, so that the pipeline 46 is not blocked. At this time, the airflow can be transported to the stabilizing box 31 through the pipeline 46, and then the airflow offset pipe has a certain degree of offset effect on the airflow outside the window 7.
