Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to a conveying device. Background Art

[0002] Currently, the raw material area relies solely on the reducer's built-in backstop to prevent the conveyor from repeatedly stopping and backing up. However, the conveyor often experiences high flow rates, and repeated impacts can cause the backstop to fail, causing the conveyor to reverse and back up. This can lead to a large amount of production ore being accumulated and buried at the tail of the machine, causing equipment downtime, disrupting normal production, and placing a heavy burden on manual cleaning. Because replacing the built-in backstop online can affect the reducer's tooth clearance, the reducer must be disassembled and returned to the factory for repair. During the reducer repair period, it is difficult to eliminate the equipment hazards caused by the backstop failure. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0030] Combine Figure 1-Figure 4The embodiment of the present application provides a transport device 1, comprising a main roller 11, a transport belt 12, a check belt 20 and a drive device 30. The transport belt 12 is wound around the main roller 11, the main roller 11 is supported by the transport belt 12, the check belt 20 is arranged in the transport belt 12, the end of the check belt 20 away from the main roller 11 is a movable end 21, the movable end 21 has an initial position and a check position set at intervals on the transport belt 12, the initial position is set on the side of the check position away from the main roller 11, and the drive device 30 is connected to the check belt 20; wherein, in response to the reverse rotation of the main roller 11, the drive device 30 can drive the check belt 20 to move in the direction of the main roller 11 and be wound between the main roller 11 and the transport belt 12, and when the movable end 21 of the check belt 20 reaches the check position from the initial position, the drive device 30 stops driving, and the main roller 11 stops rotating under the action of friction.

[0031] The main roller 11 and the conveyor belt 12 are connected by transmission. The conveyor belt 12 has a built-in check valve to prevent reverse flow and material leakage. When the check valve fails and the conveyor belt 12 reverses and unloads the material, the main roller 11 also reverses. Therefore, when the main roller 11 rotates in the reverse direction, it indicates that the conveyor belt 12 is transmitting in the reverse direction at this time.

[0032] It should be noted that, combined with Figure 2 The main roller 11 is connected to a driving device. When the conveyor belt 12 reverses and unloads, the driving device will be immediately shut down. The conveyor equipment 1 also includes a tail roller 13. The conveyor belt 12 is wound around the main roller 11 and the tail roller 13 at the same time to form a loading conveyor belt 121 and a return conveyor belt 122. The loading conveyor belt 121 is located above the return conveyor belt 122. The check belt 20 is arranged between the loading conveyor belt 121 and the return conveyor belt 122. In order to facilitate the arrangement and placement of the check belt 20 and the driving device 30, in the embodiment of the present application, the check belt 20 and the driving device 30 are both applied to the return conveyor belt 122, that is, the initial position and the check position are both located on the return conveyor belt 122. The check belt 20 is rolled from the bottom of the main roller 11 between the main roller 11 and the conveyor belt 12.

[0033] Combine Figure 1-Figure 4 In the process of the check belt 20 being wound between the main roller 11 and the conveyor belt 12, since the driving device 30 is still driving the check belt 20 to move in the direction of the main roller 11, the check belt 20 will move with the main roller 11. When the movable end 21 of the check belt 20 reaches the check position from the initial position, the driving device 30 stops driving, that is, the position of the check belt 20 is fixed at this time and no longer moves, while the main roller 11 still has a tendency to reverse. Therefore, friction will be generated between the check belt 20 and the main roller 11, and under the action of this friction, the main roller 11 will stop rotating, thereby preventing the conveyor belt 12 from reversely dumping the material and improving the backlog situation at the tail of the machine.

[0034] Specifically, the end of the check belt 20 close to the main roller 11 is the check end 22. Obviously, the check end 22 is rolled between the main roller 11 and the conveyor belt 12. When the check end 22 reaches approximately Figure 4 When the movable end 21 moves from the initial position to the check position, the check end 22 just reaches the position A. At this time, the driving device 30 can stop driving, and the main roller 11 stops rotating under the action of friction.

[0035] It is worth mentioning that the transport equipment 1 provided in the embodiment of the present application is a secondary compensation for the sudden failure of the built-in check valve and the inability to replace it online. That is, the built-in check valve is the first measure to prevent reverse material spillage, and the transport equipment 1 provided in the embodiment of the present application is the second measure to prevent reverse material spillage. Under the protection of the dual measures, the situation of reverse material spillage of the conveyor belt 12 can be further improved.

[0036] In some embodiments, the driving device 30 includes a first sensor 350 and a driving mechanism 300 . The first sensor 350 is used to detect the rotation direction of the main drum 11 . The first sensor 350 and the driving mechanism 300 are electrically connected. The driving mechanism 300 is connected to the check belt 20 .

[0037] When the first sensor 350 detects that the main drum 11 is rotating in reverse, it sends a driving signal to the driving mechanism 300, which then drives the check belt 20 to move in the direction of the main drum 11. Specifically, the first sensor 350 can be a Hall effect direction sensor 351, and the Hall effect direction sensor 351 has a matching magnetic block 352. The magnetic block 352 can be installed on the main drum 11 to determine whether the main drum 11 is rotating in reverse.

[0038] The transport equipment 1 also includes a head redirecting roller 14, which is supported on the conveyor belt 12. The conveyor belt 12 and the head redirecting roller 14 are connected by transmission. When the conveyor belt 12 reverses and unloads the material, the main roller 11 reverses accordingly, and the head redirecting roller 14 also reverses due to pressure. That is, when the head redirecting roller 14 rotates in the opposite direction, it also indicates that the conveyor belt 12 is transmitting in the opposite direction at this time. Therefore, the first sensor 350 can also be installed on the head redirecting roller 14, and there is no restriction on this.

[0039] In some embodiments, the driving mechanism 300 includes a driving unit 310 and a transmission unit 320. The transmission unit 320 is connected to the check belt 20. The driving unit 310 can drive the check belt 20 to move toward the main roller 11 through the transmission unit 320 and enter between the main roller 11 and the conveyor belt 12.

[0040] The drive unit 310 may include a drive motor 311 and a coupling 312. The drive motor 311 and the coupling 312 are in transmission connection. The coupling 312 is connected to the transmission unit 320, so that the driving force of the drive electrode can be transmitted to the transmission unit 320 to drive the check belt 20 to move. Specifically, the drive motor 311 rotates forward to drive the check belt 20 to move in a direction closer to the main drum 11, and the drive motor 311 rotates forward to drive the check belt 20 to move in a direction away from the main drum 11.

[0041] The drive mechanism 300 also includes a control panel 330 and a dual contactor 340. The first sensor 350 and the drive mechanism 300 are electrically connected to the control panel 330 and the dual contactor 340. After receiving the signal from the control panel 330, the dual contactor 340 controls the external 380V current to be connected, and controls the forward and reverse rotation of the motor through the "ABC" and "ACB" wiring sequence. That is, when the first sensor 350 detects that the main drum 11 is reversed, it sends a signal to the control panel 330. The control panel 330 then outputs a signal to the forward contactor in the dual contactor 340, controlling the external power supply of the dual contactor 340 to be energized, causing the drive motor 311 to rotate forward, thereby driving the check belt 20 to move in the direction close to the main drum 11.

[0042] In some embodiments, the transmission unit 320 includes a transmission member 321, a connecting member 322 and a drive assembly 323 relatively arranged on both sides of the conveyor belt 12, the transmission member 321 is transmission-connected between the two drive assemblies 323, the drive unit 310 is transmission-connected to one of the drive assemblies 323, the connecting member 322 is connected to the two drive assemblies 323, and is connected to the check belt 20.

[0043] Because the drive unit 310 is in transmission connection with one of the drive assemblies 323, the transmission member 321 is in transmission connection between the two drive assemblies 323. That is, when the drive unit 310 drives one of the drive assemblies 323 to move, the other drive assembly 323 also moves simultaneously under the drive of the transmission member 321. Because the connecting member 322 is connected to both drive assemblies 323 and to the check belt 20, the connecting member 322 moves with the two drive assemblies 323 and drives the check belt 20 to move.

[0044] In some embodiments, the driving assembly 323 includes a mounting member 3231, a transmission member 3232 and at least two rotating members 3233, at least two rotating members 3233 are arranged on the mounting member 3231, the driving unit 310 is connected to one of the rotating members 3233, the transmission member 3232 is arranged around at least two rotating members 3233, the transmission member 321 is transmission-connected to the rotating member 3233, and the connecting member 322 is connected to the transmission member 3232.

[0045] Since the driving unit 310 is connected to one of the rotating parts 3233, the conveying part 3232 is arranged around at least two rotating parts 3233, and the transmission part 321 is in transmission connection with the rotating parts 3233, the driving unit 310 drives one of the rotating parts 3233 to rotate, and the two conveying parts 3232 rotate around the corresponding two rotating parts 3233 at the same time. Since the connecting part 322 is connected to the conveying part 3232, the connecting part 322 rotates with the conveying part 3232 and drives the check belt 20 to move.

[0046] Specifically, the rotating member 3233 is a sprocket, the conveying member 3232 is a chain, and the transmission member 321 is a rotating shaft. The mounting member 3231 may include two bases spaced apart, and the two rotating members 3233 are respectively disposed on the two bases.

[0047] In some embodiments, when the main drum 11 rotates forward again, the driving device 30 can drive the check belt 20 to move away from the main drum 11 and pull the check belt 20 out from between the main drum 11 and the conveyor belt 12.

[0048] When the main roller 11 is stopped from reversing, the conveyor belt 12 needs to be restarted. At this time, the main roller 11 rotates forward again. Therefore, the driving device 30 needs to drive the check belt 20 to move away from the main roller 11 and pull the check belt 20 out from between the main roller 11 and the conveyor belt 12 to avoid the check belt 20 hindering the rotation of the main roller 11. The movable end 21 of the check belt 20 needs to return to the initial position from the check position to prepare for stopping the main roller 11 from reversing next time.

[0049] In some embodiments, the transport equipment 1 further includes a second sensor 40 and a third sensor 50, the second sensor 40 is set at the initial position, and the third sensor 50 is set at the check position. When the second sensor 40 detects that the end of the check belt 20 reaches the initial position from the check position, or the third sensor 50 detects that the check belt 20 reaches the check position from the initial position, the drive device 30 stops driving.

[0050] That is, when the main drum 11 reverses and the driving device 30 drives the check belt 20 from the initial position to the check position, the third sensor 50 sends a stop signal to the driving device 30, and the driving device 30 stops driving; when the main drum 11 rotates forward again and the driving device 30 drives the check belt 20 from the check position to the initial position, the second sensor 40 sends a stop signal to the driving device 30, and the driving device 30 stops driving.

[0051] Specifically, the second sensor 40 and the third sensor 50 are both proximity switches, and in order to facilitate the installation of the second sensor 40 and the third sensor 50, the two bases can be respectively arranged at the initial position and the check position, so that the second sensor 40 and the third sensor 50 are respectively arranged on the two bases.

[0052] In some embodiments, the transport equipment 1 further includes a supporting device 60 , which is disposed on the transport belt 12 , and the supporting device 60 is supported on the check belt 20 , so that the check belt 20 is spaced apart from the transport belt 12 .

[0053] Since the check belt 20 needs to be wound between the main roller 11 and the conveyor belt 12, it is made of a soft material. Specifically, the check belt 20 can be made of a non-slip belt. Since the conveyor belt 12 is also made of a soft material, if the check belt 20 is placed in close contact with the conveyor belt 12, the friction between the check belt 20 and the conveyor belt 12 will make it difficult for the drive device 30 to drive the check belt 20 to move. Therefore, it is necessary to support the check belt 20 with the support device 60 to ensure that there is a gap between the check belt 20 and the conveyor belt 12. In this way, the drive device 30 can easily drive the check belt 20 to move. In addition, since there is a gap between the check belt 20 and the conveyor belt 12, the conveyor belt 12 is wound around the main roller 11, that is, there is a height difference between the check belt 20 and the bottom of the main roller 11. Therefore, in addition to the driving force of the drive device 30, the check belt 20 can also enter between the main roller 11 and the conveyor belt 12 under the action of its own weight.

[0054] In some embodiments, the supporting device 60 includes a base 61, two support rods 62 and two first guide rollers 63. The base 61 is arranged on the conveyor belt 12, the two support rods 62 are arranged relative to the base 61, the two first guide rollers 63 are arranged vertically between the two support rods 62, and the check belt 20 is arranged between the two first guide rollers 63.

[0055] The two first guide rollers 63 are arranged along the width direction of the conveyor belt 12. Since the check belt 20 is arranged between the two first guide rollers 63, the two first guide rollers 63 can provide guidance for the movement of the check belt 20 during its movement, making the movement of the check belt 20 smoother.

[0056] In some embodiments, the supporting device 60 further includes two second guide rollers 64 . The two second guide rollers 64 are disposed on the base 61 and are respectively disposed on both sides of the check belt 20 .

[0057] The second guide roller 64 can be arranged perpendicular to the first guide roller 63. Since the two second guide rollers 64 are arranged on both sides of the check belt 20, the movement of the check belt 20 can be limited to prevent the check belt 20 from deviating, ensuring that the check belt 20 can enter between the main roller 11 and the conveyor belt 12.

[0058] In addition, slide rails are provided on the base 61 and the support rod 62. The first guide roller 63 is slidably set in the slide rail of the support rod 62, and the second guide roller 64 is slidably set in the slide rail of the base 61, so that the positions of the first guide roller 63 and the second guide roller 64 can be adaptively adjusted.

[0059] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0060] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
