Technical Field

[0001] The invention relates to the field of belt conveyors, and in particular to a broken belt catching device. Background Art

[0002] At present, in the field of material transportation, belt conveyors have become an indispensable mechanical equipment in the transportation process. Belt conveyors use conveyor belts as carriers for transporting materials. The reliability of the conveyor belt will directly affect the reliability of the belt conveyor. There is friction in the conveyor belt during transportation. The material transportation is achieved through friction, which leads to greater friction in the conveyor belt and the possibility of belt breakage. The original technology only uses the method of regular maintenance to check the wear of the conveyor belt, lacks early warning and monitoring of conveyor belt breakage, and it is difficult to take timely measures when the conveyor belt breaks, which will not only cause property losses, but also the possibility of safety accidents, affecting the personal safety of front-line workers. Therefore, it is necessary to design a better monitoring technology to provide timely feedback when the conveyor belt breaks to solve the above problems. Summary of the invention

However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the protection scope of the present invention.

In the description of this article, directional terms such as "upper", "lower", "front", and "rear" are used. It should be understood that these directional terms are relative concepts. They are used to describe and clarify relative positions, and their corresponding specific orientations can change accordingly according to the change of the orientation of the present invention.

[0014] like Figures 1 to 4 As shown, the present invention provides a broken belt capturing device, including a roller 1, a capturing device, a signal acquisition module and a control center. The control center processes and judges the signal collected by the signal acquisition device and then controls the capturing device. The signal acquisition includes a piezoelectric device 3 arranged on both sides of a conveyor belt 2 of a belt conveyor. An ammeter 4 is arranged on the piezoelectric device 3 for collecting the current signal generated by the piezoelectric device 3 and transmitting it to the control center.

[0015] The conveyor belt 2 is arranged on the roller 1, and tracks are arranged on both sides of the conveyor belt 2, and the tracks include an upper track 7 and a lower track 9. The catcher includes an upper catcher 8 and a lower catcher 10, wherein the upper catcher 8 is arranged on the upper track 7 and can move along the upper track 7 under the action of electric drive, and the lower catcher 10 is arranged on the lower track 9 and can catch the position where the belt breaks according to the feedback signal from the control center.

[0016] In this embodiment, the signal acquisition device also includes a visual acquisition device 6 arranged above the belt conveyor, and the visual acquisition device 6 is installed on the frame 5 of the belt conveyor. The visual acquisition device 6 includes a left visual collector and a right visual collector and a central visual collector arranged between the left visual collector and the right visual collector. The central visual collector is used to collect image signals of the current loaded conveyor belt 2, and the left visual sensor and the right visual sensor are used to collect image signals of the unloaded conveyor belt 2 below.

[0017] like Figure 3 and Figure 4 As shown, the present invention installs a visual acquisition device 6 on a frame 5, and a visual acquisition device 6 is arranged in the center above the conveyor belt 2 to complete the image information acquisition of the current loaded part of the conveyor belt 2. A visual acquisition device 6 is installed on each side above the conveyor belt 2, and the device realizes the image information of the current unloaded part of the conveyor belt 2, and feeds back the image information to the control center. The control center analyzes the position where the current broken or cracked belt occurs according to the image information fed back by the visual acquisition device 6. If the broken or cracked belt occurs on the loaded side, the upper capture device 8 is driven to capture the broken or cracked belt position. The upper capture device 8 is installed on the upper rail 7, and the upper capture device 8 can slide on the upper rail 7. If the broken or cracked belt occurs on the unloaded side, the lower capture device 10 captures the position where the broken belt occurs on the unloaded side of the conveyor belt 2. The lower capture device 10 is installed on the lower rail 9, and can slide along the lower rail 9. According to the feedback signal from the control center, it runs to the sliding position for capture, so as to prevent the belt conveyor from endangering production safety due to broken belt or cracking.

[0018] In this embodiment, the control center receives the current signal of the piezoelectric device 3 collected by the ammeter 4 and the signal collected by the visual collection device 6 for feedback processing to determine the belt breakage of the conveyor belt 2 and the location where the breakage occurred.

[0019] In this embodiment, the piezoelectric device 3 generates a current signal when the conveyor belt 2 is deformed, and the ammeter 4 feeds back the current signal generated by each piezoelectric device 3 to the control center. The control center can read and process the current signal fed back from the ammeter 4, and judge the operating status of the conveyor belt 2 of the current belt conveyor according to the current signal. When the belt breaks, the current signal is greater than the preset value, and a capture signal is given.

[0020] In this embodiment, the visual acquisition device 6 determines whether the current belt conveyor belt has cracks and the location of the fault based on the visual signals collected at various locations of the current belt conveyor belt 2 and gives a capture signal to drive the capture device to capture the conveyor belt.

[0021] In the present invention, the conveyor belt of the belt conveyor will be elongated when transporting materials. If the current conveyor belt of the belt conveyor has the hidden danger of belt breakage, the elongation of the conveyor belt of the belt conveyor will be too large, and the trial current of the piezoelectric device 3 will increase due to the excessive deformation. The current feedback by the current ammeter 4 is used to judge whether the current conveyor belt has the hidden danger of belt breakage. At the same time, the visual acquisition device 6 is used to collect the image signal of the current conveyor belt 2. When the belt conveyor is impacted, the deformation of the conveyor belt 2 will increase rapidly until the conveyor belt 2 cracks or even breaks. This process is not easy to collect and judge using the piezoelectric device 3. The visual method can more accurately judge the working condition of the current conveyor belt of the belt conveyor. The control center is used to analyze the image signal to obtain the current position of the broken belt. The broken belt position is captured in time by the capture device to prevent the belt conveyor from causing safety hazards during the operation of the belt conveyor due to the broken belt.

[0022] The implementation schemes in the above embodiments can be further combined or replaced, and the embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various changes and improvements made to the technical solutions of the present invention by professional and technical personnel in this field all belong to the protection scope of the present invention.
