Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a liquid automatic protector for belt conveyors. Background Technology

[0002] During belt operation, various factors such as uneven belt tension, unbalanced material distribution, and installation deviations of rollers or idlers can cause the belt to deviate from its intended running trajectory, resulting in belt misalignment. This problem not only reduces transmission efficiency and accelerates wear on the belt edges, but can also lead to material spillage, and in severe cases, even equipment damage and safety accidents.

[0003] Traditional belt alignment methods, such as manual adjustment or simple mechanical adjustment devices, have significant drawbacks, including insufficient alignment accuracy, cumbersome adjustment processes, and the inability to monitor and adjust in real time. With the continuous advancement of industrial automation and intelligent technologies, the market is placing increasingly stringent demands on the stability and intelligence level of belt transmission systems. Utility Model Content

[0004] To address some of the problems existing in the prior art, this utility model provides a liquid automatic protector for belt conveyors, which can monitor the belt's operating status in real time. Once a deviation is detected, it immediately and automatically activates the correction mechanism to adjust the belt and quickly return it to the predetermined track.

[0005] To achieve the above objectives, this utility model provides a liquid-type automatic protector for belt conveyors, comprising a liquid-type automatic protector body, the liquid-type automatic protector body including a fixed frame, an upper belt correction structure provided at the upper end of the fixed frame, a lower belt correction structure provided at the lower end of the fixed frame, the upper belt correction structure including an upper belt frame, and an upper detection drive wheel provided on one side of the upper belt frame.

[0006] As a further improvement of this utility model, in order to enhance the support and guiding function of the belt, make the correction action faster and more accurate, and help to correct the belt deviation in a timely manner, the upper belt correction structure is also equipped with an upper oil pump on the upper belt frame. The upper oil pump is connected to the upper detection drive wheel. The upper belt frame is equipped with multiple sets of upper trough-shaped idlers, one set of which is located in the middle section of the upper belt frame, and the remaining upper trough-shaped idlers are located on both sides, forming a U-shaped structure.

[0007] As a further improvement of this utility model, in order to further enhance the stability and reliability of the belt deviation correction system, facilitate fine-tuning when the belt deviates, and improve the accuracy of belt deviation correction, a connecting beam is provided between the upper belt conveyor frame and the upper detection drive wheel. A cylinder mounting seat is provided on the connecting beam, and an upper composite cylinder is provided on the cylinder mounting seat. An upper self-aligning idler is provided between the upper belt conveyor frames.

[0008] As a further improvement of this utility model, in order to realize the transmission of power from the hydraulic cylinder to the roller, provide continuous power support for the correction system, and ensure the smooth operation of the correction action, a piston rod is provided at the output end of the upper composite hydraulic cylinder. The piston rod is configured to cooperate with the upper self-aligning roller. The upper oil pump is configured to cooperate with the upper composite hydraulic cylinder through an oil circuit and provide power to the upper composite hydraulic cylinder.

[0009] As a further improvement of this utility model, in order to achieve precise correction of the lower belt and provide good support and guidance, which helps to maintain the stable operation of the belt, the lower belt correction structure includes a lower correction frame, a lower adjustment detection wheel is provided on one side of the lower correction frame, a lower adjustment oil pump is provided below the lower adjustment detection wheel, and a lower adjustment idler is provided on the lower correction frame. The lower adjustment idler is arranged in a strip-shaped structure.

[0010] As a further improvement of this utility model, in order to achieve fine adjustment of the lower belt and enhance the flexibility and adaptability of the belt correction system to cope with belt misalignment under different working conditions, a lower self-aligning idler is provided between the lower adjusting idler and the lower belt correction frame. The lower belt correction structure is also provided with a lower adjusting cylinder. A connecting rod is provided at the output end of the lower adjusting cylinder, and the connecting rod is connected to the lower self-aligning idler.

[0011] When this utility model is in operation, it can be divided into an upper correction process and a lower correction process. The working processes of the upper correction structure and the lower correction mechanism can be described in detail as follows:

[0012] Upper correction structure workflow

[0013] Initial state:

[0014] The upper belt conveyor frame is mounted above the belt conveyor via a fixed frame. Upper trough-shaped idlers are arranged in a U-shape on the upper belt conveyor frame, providing stable support for the belt. The upper detection drive wheel is located on one side of the upper belt conveyor frame, maintaining contact with the belt and ready to monitor its operating status at any time. The upper oil pump is mechanically connected to the upper detection drive wheel. The upper composite oil cylinder and its piston rod, as well as the upper self-aligning idlers, are all in their initial positions, awaiting startup.

[0015] Belt conveyor operation monitoring:

[0016] When the belt starts running, its running trajectory is continuously monitored. If the belt deviates from its designated path, meaning the edge of the belt touches a specific position on the upper detection drive pulley, the belt makes contact with the upper detection drive pulley, causing it to rotate. The upper detection drive pulley transmits this signal to the upper oil pump through a mechanical structure. Upon receiving the signal, the upper oil pump starts, meaning the upper detection drive pulley rotates, driving the upper oil pump to output pressurized oil. This pressurized oil is generated through the rotation of internal gears or vanes and is then transported to the upper composite cylinder through the oil pipe assembly.

[0017] After receiving pressurized oil, the piston rod inside the upper composite cylinder extends or retracts, and this action is transmitted to the upper self-aligning idler roller via a mechanical connection. The upper self-aligning idler roller then rotates or moves, changing the local support angle of the belt and generating a corrective force opposite to the direction of belt deviation, gradually bringing the belt back to the correct running track. The upper detection drive wheel continues to monitor the belt's running status, and if the belt deviates again, the above process is repeated for automatic adjustment.

[0018] Lower correction structure workflow

[0019] Initial state:

[0020] The lower self-aligning frame is mounted below the belt conveyor via a fixed frame. Lower adjusting idlers are arranged in a strip-like structure on the lower self-aligning frame to support the lower belt. The lower adjusting detection wheel is located on one side of the lower self-aligning frame, maintaining contact with the lower belt, ready to monitor the belt's operating status at any time. The lower adjusting oil pump is mechanically connected to the lower adjusting detection wheel. The lower adjusting cylinder and its connecting rod, as well as the lower self-aligning idlers, are all in their initial positions, awaiting activation.

[0021] Belt conveyor operation monitoring:

[0022] When the lower belt starts running, its running trajectory is continuously monitored. If the lower belt deviates from its designated path, that is, if the lower belt comes into contact with the lower adjustment detection wheel, the lower adjustment detection wheel will rotate and transmit this signal to the lower adjustment oil pump through a mechanical structure.

[0023] Upon receiving a signal, the lower adjusting oil pump starts, generating pressurized oil, which is then delivered to the lower adjusting cylinder via an oil pipe. The rotation of the lower adjusting detection wheel drives the lower adjusting oil pump to output pressurized oil. Upon receiving the pressurized oil, the piston inside the lower adjusting cylinder extends or retracts. This action is transmitted to the lower self-aligning roller via a connecting rod, directly causing the lower adjusting roller to rotate.

[0024] The movement of the lower self-aligning idler or lower adjusting idler changes the local support points of the lower belt, generating a corrective force opposite to the direction of belt deviation, gradually bringing the lower belt back to the correct running trajectory. The lower adjusting detection wheel continues to monitor the running status of the lower belt; if the belt deviates again, the above process is repeated for automatic adjustment.

[0025] The beneficial effects of this utility model are as follows:

[0026] Improve transportation efficiency and stability:

[0027] By incorporating upper and lower belt correction structures, this protector effectively corrects belt misalignment, ensuring the belt maintains a stable running trajectory during transportation. This helps reduce transportation interruptions and malfunctions caused by belt misalignment, thereby improving transportation efficiency.

[0028] Automatic deviation correction improves transportation efficiency:

[0029] This invention, through its upper and lower belt misalignment correction structures, enables real-time monitoring of the belt's trajectory. Once belt misalignment occurs, the corresponding correction structure immediately activates, adjusting the position or angle of the self-aligning idlers to generate a correction force opposite to the direction of belt deviation, quickly returning the belt to its correct running track. This automatic correction function effectively prevents malfunctions such as material spillage, machine downtime, and even belt tearing caused by belt misalignment, significantly improving the operating efficiency and stability of the belt conveyor.

[0030] Energy saving and environmental protection, reducing energy consumption:

[0031] Compared with traditional mechanical or electric correction devices, the hydraulic automatic protector of this invention does not require an external power supply. Instead, it uses the power of the belt running to drive the oil pump through the upper detection drive wheel.

[0032] Safe and reliable, protects the belt:

[0033] This utility model's liquid-type automatic belt protector does not damage the belt during the belt alignment process. It adjusts the belt's trajectory by changing the position or angle of the self-aligning idler rollers, rather than through forced compression or friction. This design effectively avoids belt wear or damage caused by improper alignment, extending the belt's service life. Furthermore, the entire device can monitor the belt's operating status in real time and make automatic adjustments. Attached Figure Description

[0049] When this utility model is in operation, it can be divided into an upper correction process and a lower correction process. The working processes of the upper correction structure and the lower correction mechanism can be described in detail as follows:

[0050] Upper correction structure workflow

[0051] Initial state:

[0052] The upper belt conveyor frame 4 is mounted above the belt conveyor via a fixed frame 1. Upper trough-shaped idlers 7 are arranged in a U-shape on the upper belt conveyor frame 4, providing stable support for the belt. The upper detection drive wheel 5 is located on one side of the upper belt conveyor frame 4, maintaining contact with the belt and ready to detect its operating status at any time. The upper oil pump 6 is mechanically connected to the upper detection drive wheel 5. The upper composite oil cylinder 10 and its piston rod 12, as well as the upper self-aligning idler 11, are all in their initial positions, awaiting startup.

[0053] Belt conveyor operation monitoring:

[0054] When the belt starts running, its running trajectory is continuously monitored. If the belt deviates from its designated path, i.e., the edge of the belt touches a specific position on the upper detection drive wheel 5, the belt makes contact with the upper detection drive wheel 5, causing the upper detection drive wheel 5 to rotate. The upper detection drive wheel 5 transmits this signal to the upper oil pump 6 through a mechanical structure. Upon receiving the signal, the upper oil pump 6 starts, i.e., the upper detection drive wheel 5 rotates, driving the upper oil pump 6 to output pressurized oil. The pressurized oil is generated through the rotation of internal gears or blades and is transported to the upper composite cylinder 10 through the oil pipe assembly.

[0055] After receiving pressurized oil, the piston rod 12 inside the upper composite cylinder 10 extends or retracts. This action is transmitted to the upper self-aligning idler 11 via a mechanical connection. The upper self-aligning idler 11 then rotates or moves, changing the local support angle of the belt and generating a corrective force opposite to the direction of belt deviation, gradually bringing the belt back to the correct running trajectory. The upper detection drive wheel 5 continues to monitor the belt's running status. If the belt deviates again, the above process is repeated for automatic adjustment.

[0056] Lower correction structure workflow

[0057] Initial state:

[0058] The lower self-aligning frame 13 is mounted below the belt conveyor via a fixed frame 1. Lower adjusting rollers 16 are arranged in a strip-like structure on the lower self-aligning frame 13 to support the lower belt. A lower adjusting detection wheel 14 is located on one side of the lower self-aligning frame 13, maintaining contact with the lower belt and ready to monitor its operating status at any time. The lower adjusting oil pump 15 is mechanically connected to the lower adjusting detection wheel 14. The lower adjusting cylinder 18 and its connecting rod 19, as well as the lower self-aligning roller 17, are all in their initial positions, awaiting activation.

[0059] Belt conveyor operation monitoring:

[0060] When the lower belt starts running, its running trajectory is continuously monitored. If the lower belt deviates from its designated path, that is, if the lower belt comes into contact with the lower adjustment detection wheel 14, the lower adjustment detection wheel 14 will rotate and transmit this signal to the lower adjustment oil pump 15 through a mechanical structure.

[0061] Upon receiving a signal, the lower adjusting oil pump 15 starts, generating pressurized oil, which is then delivered to the lower adjusting oil cylinder 18 via an oil pipe. This causes the lower adjusting detection wheel 14 to rotate, driving the lower adjusting oil pump 15 to output pressurized oil. Upon receiving the pressurized oil, the piston inside the lower adjusting oil cylinder 18 extends or retracts. This action is transmitted to the lower self-aligning roller 17 via the connecting rod 19, directly causing the lower adjusting roller 16 to rotate.

[0062] The movement of the lower self-aligning idler 17 or the lower adjusting idler 16 changes the local support point of the lower belt, generating a corrective force opposite to the direction of belt deviation, causing the lower belt to gradually return to the correct running trajectory. The lower adjusting detection wheel 14 continues to monitor the running status of the lower belt, and if the belt deviates again, the above process is repeated for automatic adjustment.
