[0031] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The present application embodiment provides a tubular belt conveyor, such as Figure 1As shown, the tubular belt conveyor includes a frame 1, a detection mechanism 2 and a replacement mechanism 3, wherein the frame 1 is provided with at least two mounting frames 11 along the length direction, each mounting frame 11 is provided with a first slideway 12 arranged coaxially, and a roller group 4 is provided in the first slideway 12, and the roller group 4 includes a plurality of rollers 41 connected to each other. That is to say, in the roller group 4, each roller 41 is connected end to end in sequence. Specifically, the number of mounting frames 11 can be set according to actual conditions, and no specific limitation is made here.

[0033] The detection mechanism 2 is used to detect whether each roller 41 has a fault, and when the detection mechanism 2 detects that a roller 41 of the roller group 4 has a fault, the replacement mechanism 3 can move along the length direction of the frame 1 to the position where the failed roller 41 is located, and replace the corresponding roller group 4. Specifically, the detection mechanism 2 has optical, temperature and other detection capabilities. How the detection mechanism 2 detects whether the roller 41 has a fault belongs to the existing technology and is not repeated here to save space.

[0034] Specifically, the number of rollers 41 in each roller group 4 is the same, but there is no limit on the number of rollers 41 in each roller group 4. Figure 4 As shown, in the present embodiment, each roller group 4 includes three rollers 41, the first slide 12 is an arc-shaped structure, the three rollers 41 are arranged along the arc-shaped structure, and the center of the arc-shaped structure is located above it, and the number of rollers 41 provided on the mounting frame 11 may be only the three rollers 41 contained in the roller group 4, and may also include rollers 41 located above the roller group 4, that is, the mounting frame 11 is provided with a plurality of rollers 41, and the three rollers 41 located below form a roller group 4 connected end to end in sequence. This part of the rollers 41 is the main force-bearing component during use, and is therefore prone to damage. When damage occurs, it can be replaced by a replacement mechanism 3, which can improve economy compared to the solution of replacing all the rollers 41.

[0035] The replacement mechanism 3 includes a storage part 31, a second slide 32 and a driving part 33, wherein the storage part 31 is used to store the roller group 4, the second slide 32 can be connected between the first slide 12 and the storage part 31, and when the storage part 31, the second slide 32 and the first slide 12 are connected in sequence, a replacement slide can be formed, and the driving part 33 can drive the roller group 4 located in the replacement slide to slide along the replacement slide. If the driving part 33 first drives the roller group 4 that has failed in the first slide 12 to slide along the replacement slide to the storage part 31, and then drives the new roller group 4 in the storage part 31 to slide along the replacement slide to the first slide 12, the replacement of the roller group 4 can be completed.

[0036] The tubular belt conveyor provided in this embodiment is provided with a first slide 12 on the mounting frame 11, and a second slide 32 and a storage part 31 are provided on the replacement mechanism 3. The driving part 33 drives the roller group 4 to slide so as to realize automatic replacement of the failed roller group 4. No manual replacement operation is required, which can achieve the purpose of saving time and labor and facilitate improving the replacement efficiency of the rollers 41.

[0037] The detection mechanism 2 can move along the length direction of the frame 1 to detect each roller 41 of the roller group 4 of each mounting frame 11. At the same time, the replacement mechanism 3 can also move along the length direction of the frame 1 to replace the roller group 4 of each mounting frame 11.

[0038] Specifically, Figure 1-Figure 3 As shown, a sliding platform 5 is provided above the frame 1, and both the detection mechanism 2 and the replacement mechanism 3 are provided with the sliding platform 5, and the sliding platform 5 can move relative to the frame 1 along its length direction, and drive the detection mechanism 2 and the replacement mechanism 3 to move simultaneously along the length direction of the frame 1. Alternatively, the detection mechanism 2 and the replacement mechanism 3 can also be provided to be independent of each other, and can move independently relative to the frame 1, and the provision of the sliding platform 5 can simplify the overall structure.

[0039] Of course, the sliding platform 5 may also be provided separately and movable along the length direction of the frame 1 . When the sliding platform 5 is provided above the frame 1 , the overall structure can be simplified and the occupied space can be reduced.

[0040] A slide rail 13 is also provided at the top of the frame 1, and the slide rail 13 is provided with a plurality of slot groups along its length direction, and each slot group is respectively arranged in a one-to-one correspondence with each mounting frame 11, and each slot group includes a plurality of slots 14. The sliding platform 5 is provided with a pulley 51 that can slide along the slide rail 13, and the pulley 51 of the sliding platform 5 can be respectively arranged in a one-to-one correspondence with each slot 14 of the slot group, and the pulley 51 can slide along the slide rail 13 until it is partially located in the slot 14, so as to limit the sliding of the sliding platform 5.

[0041] In detail, the position of each slot 14 of each slot group is set to correspond to the position of a mounting frame 11. When the pulley 51 of the sliding platform 5 slides along the slide rail 13 until each pulley 51 is partially located in each slot 14 of the same slot group, the sliding of the sliding platform 5 is blocked, indicating that at this time, the sliding platform 5 drives the detection mechanism 2 and / or the replacement mechanism 3 to slide to the position of a mounting frame 11. The detection mechanism 2 can detect the roller 41 of the mounting frame 11. If the roller 41 fails, the replacement mechanism 3 can replace the roller group 4 of the mounting frame 11. If the roller 41 of the mounting frame 11 is not faulty, the sliding platform 5 can continue to slide along the slide rail 13 to the next slot group.

[0042] The pulley 51 is partially located in the slot 14, and the slot 14 can limit the sliding platform 5 through the pulley 51, and can continue to slide along the slide rail 13 under the driving action of the driving force (here, a driving mechanism can be set separately, such as a motor and a screw assembly, or a motor, a gear and a rack assembly). When the pulley 51 is partially located in the slot 14, the bottom 1 / 3 of the height of the pulley 51 can be located in the slide groove.

[0043] like Figure 1 and Figure 2 As shown, the second slideway 32 and the driving part 33 are both arranged on the sliding platform 5, and the storage part 31 includes a trolley 311. The trolley 311 is provided with a plurality of third slideways 312 arranged in parallel. The third slideway 312 is used to place the roller group 4. The trolley 311 is provided on the sliding platform 5 and can move relative to the sliding platform 5 along the length direction of the frame 1 so that the third slideway 312 is connected to the second slideway 32. In other words, by moving the sliding platform 5 along the length direction of the frame 1, the second slideway 32 can be driven to move to communicate with the corresponding first slideway 12, and then the trolley 311 can slide on the sliding platform 5 and drive the corresponding third slideway 312 to communicate with the second slideway 32, thereby forming a replacement slideway, so as to facilitate the replacement of the roller group 4.

[0044] Specifically, among the third slides 312 of the storage part 31 , at least one third slide 312 is vacant and is used to place the failed roller group 4 , and the remaining third slides 312 can be used to place new or non-faulty roller groups 4 .

[0045] In this embodiment, the first slideway 12, the second slideway 32 and the third slideway 312 are all slideways with a C-shaped cross-section, and the drive chain 332 is located in the slideway and can slide along the slideway, or each slideway can be set as a track, and the drive chain 332 can slide along the track by setting a slider that can slide along the track. When the slideway is set as a slideway structure, the overall structure can be simplified.

[0046] The driving part 33 includes a driving member 331 and a driving chain 332 (such as Figure 2 As shown), wherein the driving chain 332 can slide along the replacement slide under the drive of the driving member 331, and the end of the driving chain 332 is also provided with a connecting member 333, and the connecting member 333 can be detachably connected to the roller group 4. When the driving chain 332 needs to drive the roller group 4 to slide along the replacement slide, the connecting member 333 is connected to the end of the roller group 4. When the replacement is completed, the connecting member 333 can be detached from the end of the roller group 4.

[0047] In this embodiment, the specific structure of the driving member 331 is not limited. For example, it can be configured to include a motor and a driving wheel, the driving chain 332 is wound around the outer periphery of the driving wheel, the motor drives the driving wheel to rotate, and the driving chain 332 is retracted to drive the connecting member 333 to slide along the replacement slideway. Alternatively, the driving member 331 can also be configured to include a motor and a driving shaft, the driving chain 332 can be a steel wire rope and is wound around the outer periphery of the driving shaft, the motor drives the driving shaft to rotate, and the driving chain 332 is retracted to drive the connecting member 333 to slide along the replacement slideway.

[0048] The connecting member 333 is an electromagnetic member. When the connecting member 333 is powered on, it has magnetism and can be connected to the end of the roller group 4 through magnetic attraction. Then, under the action of the driving member 331, the roller group 4 is driven to slide along the replacement slideway. When the connecting member 333 is powered off, the magnetic attraction disappears, and the connecting member 333 is separated from the roller group 4. The detachable connection between the connecting member 333 and the roller group 4 is achieved through electromagnetic action, which can simplify the overall structure and detachable operation.

[0049] The tubular belt conveyor provided in this embodiment also includes a control mechanism, which is used to control the sliding platform 5 to slide along the slide rail 13, control the detection mechanism 2 to detect the roller 41, and when a failure of the roller 41 is detected, the roller group 4 can be replaced by the replacement mechanism 3, specifically controlling the trolley 311 to slide along the sliding platform 5, and controlling the driving unit 33 to drive the roller group 4 to replace. Specifically, how the control mechanism performs the above control operation through a program is already a well-known prior art for those skilled in the art, and will not be repeated here to save space.

[0050] The end of the roller group 4 is also provided with a limiter 42, which can interact with the slideway and limit the roller group 4 from sliding along the slideway. For the roller group 4 located in the storage part 31, its limiter 42 can limit the roller group 4 from sliding along the third slideway 312, and for the roller group 4 located in the first slideway 12, the limiter 42 can limit the roller group 4 from sliding along the first slideway 12, thereby ensuring the stability of the position of the roller group 4.

[0051] like Figure 6As shown, the limiting member 42 includes a rotating shaft 421, a torsion spring 422 and two clamping plates 423, wherein the rotating shaft 421 is fixed to the end of the roller group 4, the torsion spring 422 is sleeved outside the rotating shaft 421, and the clamping plate 423 is connected to the leg of the torsion spring 422, and can abut against the slideway under the action of the torsion spring 422, thereby playing a limiting role. When the connecting member 333 is in the power-on state, it can be connected to the clamping plate 423 through magnetic attraction, so that the clamping plate 423 rotates around the rotating shaft 421 and disengages from the slideway, thereby releasing the limiting effect of the limiting member 42, and then the roller group 4 slides along the slideway without restriction, and the driving chain 332 can drive the roller group 4 to slide along the slideway, thereby replacing the roller group 4.

[0052] Specifically, the embodiment does not limit how the clamping plate 423 and the slideway abut against each other to limit the sliding of the roller group 4. For example, the clamping plate 423 may abut against the side wall of the slideway to achieve position limiting through friction. Alternatively, a position limiting structure may be provided on the slideway to achieve position limiting through the abutment between the clamping plate 423 and the position limiting structure. Figure 6 As shown in the figure, when there is only one card plate 423, one leg of the torsion spring 422 is fixed to the rotating shaft 421, and the other leg of the torsion spring 422 is connected to the card plate 423. When there are two card plates 423, the two legs of the torsion spring 422 are respectively connected to the two card plates 423. The connecting member 333 is located between the two card plates 423 and can be connected along the two card plates 423 by magnetic attraction when the power is on. Figure 6 The arrow directions in FIG. 1 are close to each other and connected to the connecting member 333 (such as Figure 7 As shown), the two clamping plates 423 are separated from the slide rails respectively.

[0053] When the driving chain 332 drives the roller group 4 to slide along the slide to the target position (the third slide 312 or the first slide 12), the connecting piece 333 is powered off, the magnetic force is released, and the clamping plate 423 returns to its original position under the action of the torsion spring 422 and acts with the slide to achieve limiting.

[0054] like Figure 4 As shown, connecting parts 43 are provided at both ends of the roller group 4 and between two adjacent rollers 41. Figure 5 As shown, the connecting portion 43 includes an intermediate shaft 431 , and the end of the roller 41 is sleeved outside the intermediate shaft 431 and can rotate around the intermediate shaft 431 , and the intermediate shaft 431 can slide along the slideway.

[0055] That is to say, each roller 41 is provided with a connecting portion 43 at both ends, and the two ends of the roller 41 can be respectively mounted on two intermediate shafts 431, and the axis of the intermediate shaft 431 is perpendicular to the axis of the roller 41. The connecting portion 43 can provide support and installation for the roller 41, and can enable two adjacent rollers 41 to be connected through the connecting portion 43 while being able to rotate relative to each other around the intermediate shaft 431, thereby realizing a hinged connection.

[0056] There is no restriction on the connection method between the end of the roller 41 and the intermediate shaft 431. Figure 5 As shown, the intermediate shaft 431 is provided with a clamp 433. After the end of the roller 41 is sleeved on the intermediate shaft 431, it is limited by the compression spring 432, thereby limiting the separation of the roller 41 from the intermediate shaft 431 and ensuring that the roller 41 can stably rotate around the intermediate shaft 431.

[0057] The intermediate shaft 431 can slide along the slideway. Specifically, when the slideway is a slideway with a C-shaped cross section, a sliding member 434 can be provided at the bottom of the intermediate shaft 431. The width of the sliding member 434 is greater than the opening width of the slideway. The sliding member 434 is located in the slideway and can slide along the slideway and prevent separation from the slideway. When the slideway is a track, the intermediate shaft 431 can be provided with a sliding member 434 with a C-shaped structure. The sliding member 434 slides along the track and can prevent separation from the track.

[0058] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
