Technical Field
[0001] This invention belongs to the technical field of dynamic monitoring equipment for vibration components, specifically relating to a monitoring system for the safe operation of vibration equipment, and also to a monitoring method for the system. Background Technology
[0002] In modern chemical elastomer material production systems, vibrating conveyor equipment is responsible for conveying granular materials. The operation of the vibrating equipment relies on the eccentric shaft of the motor to perform elliptical motion. The force is decomposed by spring components, effectively dividing the material's motion into vertical and horizontal motion. This allows the material to translate horizontally and has a certain displacement in the vertical direction, ensuring that impurities are effectively removed during the medium conveying process. In actual production, after the medium enters the vibrating conveyor equipment, uneven distribution can cause some of the springs to shift during reciprocating motion. If these slight shifts are not addressed in time, long-term operation can lead to spring failure, which in turn can cause the vibrating equipment to malfunction and cause production shutdowns.
[0003] As part of vibrating equipment, springs move at high frequencies, making deviations from their operating trajectory undetectable to the naked eye. Spring failure often occurs in an instant. Timely and effective monitoring of the spring's operating status and real-time dynamic tracking of its movement trajectory are crucial safeguards against equipment malfunctions during operation. Summary of the Invention

A spring is connected to the upper spring support seat, and a lower spring support seat is connected to the end of the spring away from the upper spring support seat.

The second displacement source and the first displacement source receiver are respectively located on both sides of the spring. The first displacement source receiver is positioned opposite to the first displacement source, and the second displacement source receiver is positioned opposite to the second displacement source.
[0014] Another technical solution adopted in this invention is a monitoring method for a vibration equipment safety operation monitoring system, which is implemented according to the following steps: Step 1: When the material passes through the vibrating screen, the two motors drive the first eccentric shaft and the second eccentric shaft to perform cam elliptical motion, which in turn drives the first swinging robotic arm and the second swinging robotic arm to move. Step 2: The first and second swing robotic arms drive the vibrating screen to reciprocate. Step 3: During the movement of the vibrating screen, the spring provides elastic force. The first temperature source, the second temperature source, and the third temperature source monitor the local temperature of the spring in real time.

When the first displacement source receiver 9 and the second displacement source receiver 10 do not receive the detection signals from the first displacement source 5 and the second displacement source 12, it indicates that the running trajectory of the spring 11 has deviated. At this time, an alarm will be generated, and the alarm information will be fed back to the central control room to remind the operator to adjust the distribution of the process medium in time, correct the problem of uneven load distribution, and restore the spring 11 to the specified running trajectory in time. The first temperature source 6, the second temperature source 7, and the third temperature source 8 monitor the local temperature of the spring 11 in real time. When the local temperature rises abnormally, an alarm information is issued and transmitted to the central control room to prompt timely replacement.
[0046] Example 7 The monitoring method for a vibration equipment safety operation monitoring system shall be implemented according to the following steps: Step 1: When the material passes through the vibrating screen 1, the two motors drive the first eccentric shaft and the second eccentric shaft to make cam elliptical motion, which in turn drives the first swinging robotic arm 2 and the second swinging robotic arm 16 to move. Step 2: The first swinging robotic arm 2 and the second swinging robotic arm 16 push the vibrating screen 1 to perform reciprocating motion; Step 3: During the movement of the vibrating screen 1, the spring 11 provides elastic force. The first temperature source 6, the second temperature source 7 and the third temperature source 8 monitor the local temperature of the spring 11 in real time. The first displacement source 5 and the second displacement source 12 monitor whether the running trajectory of the spring 11 deviates.
[0047] The working principle of the vibration equipment safety operation monitoring system of the present invention is as follows: When the material passes through the vibrating screen 1, the motor drives the eccentric shaft to perform a cam elliptical motion. The eccentric shaft drives two swinging robotic arms to perform a cam elliptical motion, pushing the vibrating screen 1 to reciprocate at 30° to 45° in the direction of material movement. After receiving this reciprocating force, the material uses spring 11 to decompose the force, effectively dividing the material's motion into vertical and horizontal motion. This allows the material to translate horizontally and have a certain amount of displacement in the vertical direction, ensuring effective removal of impurities during the media conveying process. Spring 11 is limited and fixed by the upper spring support 13 and the lower spring support 14. The first displacement source receiver 9 and the second displacement source receiver 10 are not activated when the first displacement source is not detected. When the detection signal from the second displacement source 12 is received, it indicates that the running trajectory of the spring 11 has deviated. At this time, an alarm will be generated and the alarm information will be fed back to the central control room, reminding the operator to adjust the distribution of the process medium in time, correct the problem of uneven load distribution, and restore the spring to the specified running trajectory in time. The first temperature source 6, the second temperature source 7, and the third temperature source 8 monitor the local temperature of the spring 11 in real time. When the local temperature rises abnormally, an alarm message will be issued and transmitted to the central control room, prompting timely replacement. Through the above temperature and running trajectory monitoring, fatigue state can be warned in advance, turning sudden failures into planned shutdowns, fundamentally avoiding failure losses caused by spring breakage.
[0048] This invention relates to a vibration equipment safety operation monitoring system. The system utilizes a monitor to plan the spring's running trajectory and monitor its operating temperature. When the spring deviates from its running trajectory, an alarm is triggered. Upon receiving the alarm, operators promptly adjust the distribution of the process medium to correct uneven load distribution, ensuring the spring returns to its designated running trajectory. Infrared temperature measurement points are installed along the spring's running trajectory to monitor its operating temperature in real time. When the spring material reaches the expected operating time, fatigue heat is generated. This abnormality is detected promptly, and preventative shutdowns and replacements are implemented, reducing losses from unplanned maintenance and equipment downtime. The system provides early warning of fatigue conditions, transforming sudden failures into planned shutdowns, fundamentally preventing losses caused by spring breakage.

Step 3: During the movement of the vibrating screen (1), the spring (11) provides elastic force. The first temperature source (6), the second temperature source (7) and the third temperature source (8) monitor the local temperature of the spring (11) in real time. The first displacement source (5) and the second displacement source (12) monitor whether the running trajectory of the spring (11) deviates.
