Description

Technical Field

[0002] Bucket elevators, as a common vertical material conveying equipment, are widely used in industries such as mining, building materials, and chemicals. During actual operation, belt slippage is a common type of failure, which can lead to reduced equipment efficiency, material spillage, and even safety accidents. Traditional slippage detection methods mainly rely on manual inspection or contact sensors, which suffer from problems such as slow response, easy wear, and high false alarm rates. Furthermore, while some non-contact detection devices improve detection accuracy to some extent, they are complex in structure, expensive, and have stringent installation and maintenance requirements, making large-scale application in industrial settings difficult. Therefore, there is an urgent need for a slippage detection device that is simple in structure, highly reliable, and cost-effective, to achieve real-time monitoring and early warning of the bucket elevator's operating status.

[0024] Please see Figure 1-3 To achieve the above objectives, this embodiment provides a bucket elevator slippage detection device.

[0025] In this embodiment, the frame body 1 serves as the basic support structure for the entire device. It is constructed of a metal frame and installed at a fixed location on the hoist. Its function is to support all other components and ensure the stability and rigidity of the overall structure.

[0026] In this embodiment, the receiving components 2 are evenly distributed on the frame body 1. Each receiving component 2 includes a support frame 4, with both ends of the support frame 4 fixedly connected to the frame body 1. A drive roller 5 and a fixed roller 6 are sleeved on the support frame 4, with the fixed roller 6 located on both sides of the drive roller 5. The drive roller 5 directly contacts and supports the belt, while the fixed roller 6 assists in positioning and prevents belt deviation. The receiving components 2 together form the belt's rolling path, reducing friction and improving transmission efficiency.

[0027] In this embodiment, the drive mechanism 3 is located on one side of the frame body 1 and includes a roller 7 and a drive motor 8. The drive motor 8 is fixed to the frame body 1, and its output shaft is connected to the roller 7 via a coupling or a transmission belt. The roller 7 directly drives the belt to move, providing the power required by the hoist.

[0028] In this embodiment, the placement frame 9 is positioned above the rollers 7 and connected to the frame body 1. Its function is to support and fix the drive motor 8 and other auxiliary equipment, ensuring the stable operation of the drive mechanism 3.

[0029] In this embodiment, the mounting net 10 is located on one side of the roller 7 and fixed to the frame body 1. The mounting net 10 integrates an alarm 11 and a current sensor 12. The alarm 11 is used to issue an audible and visual alarm when an abnormality is detected, while the current sensor 12 monitors the current change of the drive motor 8 in real time.

[0030] In this embodiment, multiple detection probes 13 are installed on the side wall of the frame body 1 and distributed along the belt running path. The detection probes 13 are electrically connected to the alarm 11 and are used to monitor the actual running speed or position status of the belt.

[0031] In this embodiment, the baffle 14 is disposed on one side of the frame body 1, and is usually made of metal or plastic sheet to prevent material leakage or external foreign objects from interfering with the belt operation.

[0032] In this embodiment, the support plate is located at the bottom of the frame body 1 and is connected to the ground or foundation structure, which enhances the overall stability and distributes the load.

[0033] Working principle

[0034] This slippage detection device determines whether slippage has occurred by monitoring the real-time operating status of the belt and the load on the drive motor 8. The specific workflow is as follows:

[0035] Drive and transmission: The drive motor 8 drives the belt through the roller 7. The belt rolls on the transmission roller 5 and the fixed roller 6 of the receiving component 2, thereby lifting the material. The receiving component 2 reduces the resistance of the belt movement and prevents it from deviating.

[0036] Status monitoring:

[0037] Current monitoring: Current sensor 12 is electrically connected to drive motor 8 to monitor the motor's operating current in real time. When the belt is running normally, the current is stable within the rated range; if slippage occurs, the load decreases, and the current drops significantly.

[0038] Speed ​​monitoring: The detection probe 13 is arranged along the side wall of the frame to monitor the actual running speed of the belt. If the speed is lower than the set value (indicating slippage), the probe will transmit a signal to the alarm 11.

[0039] Alarm Trigger: When the current sensor 12 detects an abnormal decrease in current, or the detection probe 13 detects that the belt speed is below the threshold, the alarm 11 is triggered, emitting an audible and visual signal to remind the operator to handle the situation in a timely manner and avoid equipment damage or production interruption.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
