Description

Technical Field

[0001] The present invention relates to the technical field of intelligent conveying systems, and particularly to a tape double-layer to single-layer switching frame assembly for an intelligent conveyor. Background Art

[0002] When conveying materials, conveyors are usually used. After excavation in the roadway, the materials and bulk materials are conveyed by the conveyor. With the development of intelligence and automation, conveyors are becoming more and more intelligent and unmanned.

[0003] As the tunneling machine advances, the length of the roadway becomes longer. The conveyor is located behind mining equipment such as the tunneling machine and is used to convey the mined materials or bulk materials to the ground. As the roadway becomes longer, the length of the conveyor should adaptively become longer. Moreover, the trend of development is equipment that can follow the elongation without stopping, and can elongate automatically without manual operation.

[0004] In the original design, in order to adapt to the elongation of the roadway, a tape storage device is used to store the tape at the bottom or abdomen of the frame in advance. The wound and stored tape gradually elongates with the traction in front of the conveyor, but this tape storage can only meet the requirements of length change for a relatively short distance. In addition, after excavation by the tunneling machine, materials or bulk materials at different positions after underground exploration need to be separated and transported separately. For such a tape storage and single-layer conveyor, it is no longer possible to transport two kinds of materials. Summary of the Invention

[0005] In view of the above defects, the present invention provides a tape double-layer to single-layer switching rack assembly for an intelligent conveyor, which includes a first component and a second component. The first component includes a plurality of first support frames, a first track, a first upper idler roller, a first lower idler roller, and a first connecting member. The first support frames are arranged on the roadway ground. There are two first tracks, which are respectively arranged inside the first support frames through the first connecting member. A docking head connected to an external traction mechanism is arranged at the left end of the first track. The first upper idler roller and the first lower idler roller are arranged above and below the first track and are both connected to the first track. The upper surfaces of the first upper idler roller and the first lower idler roller are used to carry the first upper layer tape and the first lower layer tape, providing a rolling support surface for the tape to move. The first connecting member includes a first roller and a first connecting rod. One end of the first connecting rod is arranged inside the first support frame and is connected to the first support frame, and the other end is connected to the first roller. The first roller rotates relative to the first connecting rod. A transverse chute is also opened on the outer side surface of the first track, and the first roller is arranged in the transverse chute, so that the first track moves relative to the first roller. The second component includes a second support frame, a second track, a second upper idler roller, a second lower idler roller, and a second connecting member. The second support frames are arranged on the roadway ground. There are two second tracks, which are respectively arranged inside the second support frames through the second connecting member. A docking head connected to an external traction mechanism is arranged at the right end of the second track. The second upper idler roller and the second lower idler roller are arranged above and below the second track and are both connected to the second track. The upper surfaces of the second upper idler roller and the second lower idler roller are used to carry the second upper layer tape and the second lower layer tape, providing a rolling support surface for the tape to move. The second connecting member includes a second roller and a second connecting rod. One end of the second connecting rod is arranged inside the second support frame and is connected to the second support frame, and the other end is connected to the second roller. The second roller rotates relative to the second connecting rod. A transverse chute is also opened on the outer side surface of the second track, and the second roller is arranged in the transverse chute, so that the second track moves relative to the second roller. A vertical chute is also opened on the inner side wall of the first support frame, and a lifting mechanism is arranged in the vertical chute. The bottom of the lifting mechanism is fixed inside the first support frame, and the top is connected to the first connecting rod. The lifting mechanism has the function of moving up and down along the vertical chute, thereby driving the first connecting rod to move downward along the vertical chute.

[0006] In this solution, the conveyor is set as a double-layer structure. Due to the double-layer setting, only the height space for the chute lap needs to be reserved for the upper layer and the lower layer. The double-layer height difference can be achieved as long as it is not less than 0.5 meters, and it is easy to implement within the allowable height range of the roadway height. Moreover, for the double-layer designed tape, at least two unit lengths can be pre-stored. When single-layer transportation is required, the length of the tape combined into one working face is almost twice the length of the original double layer, and the effective working face is much larger than the length of the original tape for storing the tape.

[0007] When switching from double-layer to single-layer, the first track is pulled by the traction mechanism at the left front end and is in a driven state, without the need for manual intervention. Moreover, the speed and length of the driven state are synchronized with the traction mechanism, making it less prone to failures or interference, and it has strong practicality. A monitoring device can also be set up, such as a length sensor or a position sensor. When the moving length of the first track reaches a preset distance, for example, the length of the lower layer of the tape, or other length setting values that exactly overlap with the length of the lower layer of the tape, at this time, the support mechanism in the first support frame starts to act, pulling the first track and its structure to slide downward until it reaches the stroke of the support mechanism, exactly overlapping with the lower layer of the tape to form a working surface, thus completing the switching.

[0008] In the switching from double-layer to single-layer in this solution, no manual operation is required, and fully automated, intelligent, and unmanned operation can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation method

[0023] See Figures 1 - 9, a double-layer to single-layer rack assembly for a belt of an intelligent conveyor proposed by the present invention, includes a first assembly and a second assembly. The first assembly includes a plurality of first support frames 10, a first track 11, a first upper idler 12, a first lower idler 13, and a first connecting member 14. The first support frames 10 are arranged on the roadway ground. There are two first tracks 11, which are respectively arranged inside the first support frames 10 through the first connecting member 14. A docking head connected to an external traction mechanism is arranged at the left end of the first track 11. The first upper idler 12 and the first lower idler 13 are arranged above and below the first track 11 and are both connected to the first track 11. The upper surfaces of the first upper idler 12 and the first lower idler 13 are used to support the first upper layer belt 100 and the first lower layer belt 200, providing a rolling support surface for the movement of the belt. The first connecting member 14 includes a first roller 141 and a first connecting rod 142. One end of the first connecting rod 142 is arranged inside the first support frame 10 and is connected to the first support frame 10, and the other end is connected to the first roller 141. The first roller 141 rotates relative to the first connecting rod 142. A transverse chute is also opened on the outer side surface of the first track 11, and the first roller 141 is arranged in the transverse chute, so that the first track 11 moves relative to the first roller 141. The second assembly includes a second support frame 20, a second track 21, a second upper idler 22, a second lower idler 23, and a second connecting member 24. The second support frames 20 are arranged on the roadway ground. There are two second tracks 21, which are respectively arranged inside the second support frames 20 through the second connecting member 24. A docking head connected to an external traction mechanism is arranged at the right end of the second track 21. The second upper idler 22 and the second lower idler 23 are arranged above and below the second track 21 and are both connected to the second track 21. The upper surfaces of the second upper idler 22 and the second lower idler 23 are used to support the second upper layer belt 300 and the second lower layer belt 400, providing a rolling support surface for the movement of the belt. The second connecting member 24 includes a second roller and a second connecting rod. One end of the second connecting rod is arranged inside the second support frame 20 and is connected to the second support frame 20, and the other end is connected to the second roller. The second roller rotates relative to the second connecting rod. A transverse chute is also opened on the outer side surface of the second track 21, and the second roller is arranged in the transverse chute, so that the second track 21 moves relative to the second roller. A vertical chute is also opened on the inner side wall of the first support frame 10, and a lifting mechanism 101 is arranged in the vertical chute. The bottom of the lifting mechanism 101 is fixed inside the first support frame 10, and the top is connected to the first connecting rod 142. The lifting mechanism 101 has the function of moving up and down along the vertical chute, and further drives the first connecting rod 142 to move downward along the vertical chute.

[0024] The first upper belt 100 and the first lower belt 200 form an independent looped belt, and the second upper belt 300 and the second lower belt 400 form a looped belt. When double-layer transportation is required, chutes are arranged on the upper side of the first upper belt 100 and on the upper side of the second upper belt 300. Different materials are respectively conveyed onto the upper belt and the lower belt through the chutes to achieve separate transportation; or the same materials are conveyed simultaneously through the upper and lower layers to improve the conveying efficiency. However, as the length of the roadway extends, longer conveying lengths and distances need to be satisfied. This solution can be switched to a single conveying surface by shifting the upper belt downward to be flush with the lower belt to form a flat conveying surface. Moreover, for the switch from double-layer to single-layer in this solution, there is no need to stop the machine. The external mechanism at the left end pulls the first track 11 to move leftward, or the external mechanism on the right side pulls the second track 21 to move rightward.

[0025] When the upper layer is operating, the first support frame 10 and the lifting mechanism 101 are connected to the first roller 141 to provide the constraint for the straight-line operation of the first track 11. When the lower layer is operating, the second support frame 20 and the second roller provide the constraint for the straight-line operation of the second track 21.

[0026] When the double-layer belt is working, the lifting mechanism 101 in the first support frame 10 always maintains a jacking force to support the first track 11 above the second track 21. When the first track 11 or the second track 21 is pulled to reach the predetermined position, the lifting mechanism 101 removes the jacking force and pulls the first track 11 and the structures thereon to move downward along the vertical chute. When reaching the predetermined position, such as being flush with the second track 21, the lifting mechanism 101 stops operating, achieving the alignment of the upper belt and the lower belt. See Figures 10 - 13 。

[0027] Furthermore, the lifting mechanism 101 is an oil cylinder or a cylinder.

[0028] Furthermore, an induction mechanism is also arranged at the right end of the first support frame 10 to match with the induction mechanism arranged at the left end of the second support frame 20 for detecting whether the first track 11 moves leftward to the preset position. In a preferred embodiment, the two induction mechanisms can be distance sensors. If the detected distance between the two is less than the preset value, it indicates that the first track 11 has moved leftward by the preset length and has reached the position for docking with the second track 21. A detection signal can be sent to the outside, and then an instruction is sent to the lifting mechanism 101 through external control to control the lifting mechanism 101 to pull the first track 11 to slide downward, realizing the change from double-layer to single-layer.

[0029] See Figure 12, further, a number of first support frames 10 are also arranged near the left side of the first track 11, and a number of second support frames 20 are also arranged near the right side of the second track 21. The first support frames 10 and the second support frames 20 can move relative to the roadway ground. When the external mechanism at the left end pulls the first track 11 to move leftward, a number of the first support frames 10 on the left side also move leftward to a preset position for supporting and lapping the first track 11. When the double-layer changes to a single-layer in this solution, it is achieved by pulling the first track 11 on the left side to move leftward.

[0030] See Figure 12 , further, a connection structure 102 can also be arranged between adjacent first support frames 10. The first first support frame 10 on the leftmost side is connected to the first track 11. As the first track 11 moves leftward, it pulls the first support frame 10 to move leftward, thereby driving the adjacent first support frames 10 to move leftward. While moving, it provides a support carrier for the first guide rail, and the distance between the first support frames 10 is also controllable and stable. The connection structure 102 can be a steel wire rope or other chain-like structures with variable length, flexibility, and adaptable length that can contract and extend to a fixed length.

[0031] See Figure 7 , further, a first connecting piece 14 is also arranged inside the second support frame 20 for supporting the first track 11 and its structure, and the second track 21 and its structure.

[0032] The above has described the embodiments of this solution in detail with reference to the drawings. However, this solution is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
