The load-carrying mechanisms 5 replace the traditional roller assembly 3, enabling the belt 8 to be loaded and unloaded on the load section 81 and return section 82, reducing friction and energy consumption. The mounting position of the load-carrying mechanisms 5 can be adjusted according to the specific location of the track 7 to achieve different belt surface heights and facilitate on-site installation.

[0041] The track 7 located in the load-bearing section 81 and the track 7 located in the return section 82 are connected by the rotating devices 4 at both ends thereof. A continuous upper and lower combined rotating track 7 is adopted and installed on the bracket 9 by welding, bolts, etc. The load-bearing running mechanism 5 is in contact with the rotating device 4 to realize continuous rotation of the load-bearing running mechanism 5.

The connection between the two is horizontally rotatable on the wheel bridge 16 via a torsion spring and a bearing. The second support frame 141 is located on the side of the wheel bridge 16 closest to the belt 8, while the second support leg 142 is located on the other side of the wheel bridge 16. The angle adjustment unit 134 enables the angle adjustment and locking of the first support frame 131, replacing the traditional upper roller for carrying and removing the belt 8. The second support device 14 rotates to support the return belt 8 section, replacing the traditional lower roller.

[0044] Two first supporting devices 13 are symmetrically arranged side by side along the width direction of the adhesive tape 8 .

[0045] When the carrying mechanism 5 runs to the carrying section 81, the first support frame 131 is lifted toward the outer side of the ring of the adhesive tape 8 and drives the adhesive tape 8 to be lifted into a groove shape to carry the material; when the carrying mechanism 5 runs to the return section 82, the first support frame 131 falls to make the adhesive tape 8 flat, and the second support device 14 rotates horizontally until the second support frame 141 is in contact with the outer side of the ring of the adhesive tape 8 to hold the adhesive tape 8.

[0046] The wheel-rail belt conveyor also includes a reversing device 11 arranged between the load-bearing section 81 and the return section 82. A first reversing wheel 133 is provided on the first support leg 132, and a second reversing wheel 143 is provided on the second support leg 142. The first reversing wheel 133 and the second reversing wheel 143 respectively rotate after contacting the reversing device 11, and drive the vertical rotation of the first support leg 132 and the horizontal rotation of the second support leg 142 to realize the angle adjustment of the first support device 13, disengage and accommodate the belt 8 of the load-bearing section 81; realize the rotation of the second support device 14, which is used to disengage and support the belt 8 of the return section 82.

[0047] The reversing device 11 is mounted on the bracket 9 by welding, bolts, etc.; the reversing device 11 includes a first stopper 111 and a second stopper 112; the first stopper 111 is arranged on the side of the bracket 9 close to the bearing section 81, and the upper surface of the first stopper 111 is inclined from low to high along the running direction of the tape 8; when the first supporting device 13 runs to the bearing section 81, the first reversing wheel 133 contacts the first stopper 111, and as the tape 8 continues to run, the first reversing wheel 133 climbs on the upper surface of the first stopper 111, and the first supporting device 13 rotates around the angle adjustment unit 134 to The first support frame 131 is lifted to a fixed angle, the angle adjustment unit 134 locks the first support device 13, and the first reversing wheel 133 disengages from the first block 111; the second block 112 is arranged on the side of the bracket 9 close to the return section 82, and one of the side surfaces of the second block 112 is arranged to be an inclined surface at a certain angle to the running direction of the tape 8; when the second support device 14 runs to the return section 82, the second reversing wheel 143 contacts the side surface of the second block 112, causing the second support leg 142 to rotate around the torsion spring, and driving the second support frame 141 to rotate until the tape 8 is caught.

[0048] A tensioning device 2 is provided on the return section 82 to tension the tape 8. When the tensioning device 2 employs a weighted tensioning mechanism, a reversing device 11 is provided on either side of the tensioning device 2 along the direction of travel of the tape 8. The tape 8 first passes through the reversing devices 11, disengaging the second support frame 141. The tape then passes through the tensioning device 2 for tensioning. The reversing devices 11 then rotate the second support frame 141 again until the tape 8 is re-engaged.

[0049] The operation process of the wheel-rail belt conveyor of the present invention:

[0050] The drive mechanism 12 drives the adhesive tape 8, shaping it in the area of ​​the tail assembly 1 under the action of the roller assembly 3. Under the action of the rotating mechanism 4 and the reversing mechanism 11 at the tail assembly 1, the carrying mechanism 5 gradually adjusts the angle of the first support frame 131 of the first supporting mechanism 13. Once it reaches a fixed angle, it is locked at that fixed angle by the angle control unit. The second support frame 141 of the second supporting mechanism 14 gradually rotates, disengaging the adhesive tape 8. At this point, the carrying mechanism 5 enters the carrying section 81 from the return section 82 of the adhesive tape 8. The adhesive tape 8 drives the carrying mechanism 5 along the track 7 until it reaches an area near the drive mechanism 12. Under the action of the rotating mechanism 4 and the reversing mechanism 11 near the drive mechanism 12, the first support frame 131 of the first supporting mechanism 13 gradually retracts. The second support frame 141 of the second supporting mechanism 14 gradually rotates, carrying the adhesive tape 8. At this point, the carrying mechanism 5 enters the return section 82 of the adhesive tape 8 from the carrying section 81. Through the above-mentioned continuous rotation operation, the continuous operation of the new wheel-rail belt conveyor is realized, and the rapid and continuous transportation of materials is completed.
