Description

Technical Field

[0001] This utility model relates to a support roller that automatically monitors faults, belonging to the technical field of slag treatment equipment. Background Technology

[0002] Solid waste slag is generated during metal smelting. The slag is often treated by the drum method. During the operation of the drum or dewatering device, the drum slag treatment equipment requires support rollers to support the rotating equipment as a whole. As a common wear part, the support rollers need to be checked frequently to check their working condition.

[0003] Given a constant overall speed of rotating equipment, the rotational speed and temperature of the support rollers supporting the rotating equipment at each location should also be the same. Traditional support rollers have a simple structure and lack automatic fault monitoring. Temperature checks must be performed manually on-site using handheld temperature guns at multiple support rollers, and a timer must be used to periodically check the number of markers on each roller to determine if their rotational speeds are consistent. Manual monitoring is time-consuming, inaccurate due to darkness, and difficult to access in confined spaces. Furthermore, the long inspection periods make it difficult to detect abnormal conditions in a timely manner, impacting equipment operation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic fault monitoring support roller that can monitor the support roller temperature and rotation speed in real time, promptly detect abnormal support rollers and accurately report their location, and provide precise feedback on abnormal roller data. This assists operators in locating abnormal support rollers, promptly troubleshooting, replacing, and repairing them, ensuring stable production operations, avoiding frequent entry and exit of personnel into confined and dark spaces, effectively improving worker safety, and reducing labor intensity.

[0005] The technical solution of this utility model is: An automatic fault-monitoring support roller includes a support, an intermediate shaft, end caps, a roller, and bearings. The roller is rotatably mounted on the intermediate shaft via bearings. Both ends of the intermediate shaft are respectively mounted on the support, and end caps are provided on both sides of the roller. A temperature-sensing screw hole is provided inside the intermediate shaft, extending directly to the end of the intermediate shaft. The protective probe of the temperature-sensing element is threaded into the temperature-sensing screw hole, and the temperature-sensing probe of the temperature-sensing element extends from the temperature-sensing screw hole to the center position inside the intermediate shaft. The end caps and the roller are fixedly connected by multiple marking bolts evenly distributed along the circumference. A bracket is provided on the support, and a proximity switch is provided on the bracket, located on the side of the marking bolts.

[0006] Furthermore, the support includes a base and side support plates disposed at both ends of the base. The upper end of the side support plate is provided with an arc-shaped groove, and the end of the intermediate shaft is disposed in the arc-shaped groove. The upper end of the arc-shaped groove is fixed with a movable pressure plate by pressure plate bolts, and the movable pressure plate positions the intermediate shaft in the arc-shaped groove.

[0007] Furthermore, the bracket includes a stiffening plate, a base plate, and a vertical support plate. The base plate is fixed on the movable pressure plate, the vertical support plate is fixed on the base plate, a stiffening plate is provided between the vertical support plate and the base plate, and a proximity switch is provided on the vertical support plate.

[0008] Furthermore, an end cap gasket is connected between two adjacent marked bolts.

[0009] Furthermore, a sealing felt ring is provided between the end cap, the intermediate shaft, and the bearing.

[0010] Furthermore, the temperature sensing element and proximity switch are matched and connected to the PLC program. The PLC program continuously compares data online, automatically monitors faults, and locates the position and problem of the faulty support roller in a timely and accurate manner, saving maintenance and troubleshooting time and labor intensity.

[0011] The positive effects of this utility model are: 1. A temperature sensing element is used to precisely and automatically monitor the temperature of the support rollers at the center of the intermediate shaft. This eliminates the need for frequent manual entry into confined spaces to measure the temperature of the rollers' exterior with a handheld temperature sensor, avoiding inaccurate monitoring of the roller's outer surface by handheld devices. Real-time online monitoring of the support roller temperature allows for timely detection of abnormal support rollers and accurate reporting of their location, saving maintenance personnel time in troubleshooting.

[0012] 2. The support roller speed is monitored by measuring the number of marked bolts passing through the roller using a proximity switch. This eliminates the need for frequent manual entry into narrow spaces for visual counting, avoiding human error. The automatic speed monitoring provides timely and accurate feedback on abnormal roller data, assisting operators in locating abnormal rollers, promptly troubleshooting, replacing, and repairing faulty rollers, and ensuring stable production operation.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: An automatic fault-monitoring support roller includes a support 1, an intermediate shaft 2, end caps 3, a roller 6, and a bearing 10. The roller 6 is rotatably mounted on the intermediate shaft 2 via the bearing 10. Both ends of the intermediate shaft 2 are respectively mounted on the support 1. End caps 3 are respectively provided on both sides of the roller 6. The intermediate shaft 2 has a temperature-sensing screw hole 22 inside, which extends directly to the shaft end of the intermediate shaft 2. The center line of the temperature-sensing screw hole 22 coincides with the axis of the intermediate shaft 2. The protective probe of the temperature-sensing element 8 is threadedly connected to the temperature-sensing screw hole 22, and the temperature-sensing probe of the temperature-sensing element 8 extends from the temperature-sensing screw hole 22 into the center position inside the intermediate shaft 2. The end caps 3 and the roller 6 are fixedly connected by multiple marking bolts 4 evenly distributed along the circumference. The support 1 is provided with a bracket 91, and the bracket 91 is provided with a proximity switch 9, which is located on the side of the marking bolts 4.

[0015] This invention uses a proximity switch 9 to calculate the number of marked bolts 4 passing through roller 6 within a set time. This data is converted into the rotational speed of the support roller by a PLC program. The PLC program automatically compares the rotational speeds of multiple support rollers to monitor the working status. When the rotational speed of a support roller slows down significantly or stops, the PLC program prompts the operator to check or replace the support roller if it is faulty. A temperature sensing element 8 inside the intermediate shaft 2 extends to the center of the intermediate shaft 2 to detect the temperature inside roller 6. The PLC program compares the temperatures of multiple rollers 6 to monitor the working status. When the temperature of roller 6 rises significantly, the PLC program prompts the operator to locate the faulty support roller for inspection or replacement.

[0016] The support 1 includes a base 11 and side support plates 12 disposed at both ends of the base. The side support plates 12 are provided with arc-shaped grooves. The end of the intermediate shaft 2 is disposed in the arc-shaped groove. The upper end of the arc-shaped groove is fixed with a movable pressure plate 13 by bolts. The movable pressure plate 13 positions the intermediate shaft 2 in the arc-shaped groove.

[0017] The bracket 91 includes a stiffening plate 911, a base plate 912, and a vertical support plate 913. The base plate 912 is fixed on the movable pressure plate 13, and the vertical support plate 913 is fixed on the base plate 912 to form an L-shaped structure. A stiffening plate 911 is provided between the vertical support plate 913 and the base plate 912 to increase the connection strength. The proximity switch 9 is provided on the vertical support plate 913.

[0018] Preferably, a sealing felt ring 7 is provided between the end cap 3, the intermediate shaft 2 and the bearing 10 to increase the sealing performance.

[0019] Preferably, an end cap gasket 5 is connected between two adjacent marked bolts 4.

[0020] As attached Figure 1 As shown, this embodiment provides a support roller for automatically monitoring faults, including: a support 1, an intermediate shaft 2 on the support 1, and a roller 6 rotatably mounted on the intermediate shaft 2 via a bearing 10. A proximity switch 9 is mounted on the support 1 via a bracket 91, with the roller 6 in front of the proximity switch 9, and a marking bolt 4 is provided on the roller 6.

[0021] As attached Figure 3 As shown, the intermediate shaft 2 is provided with a lubricating oil hole 21 and a temperature measuring screw hole 22. The bottom of the lubricating oil hole 21 is adjacent to one end of the temperature measuring screw hole 22 but not connected. The other end of the temperature measuring screw hole 22 is directly connected to the end face of the intermediate shaft 2.

[0022] As attached Figure 2 As shown, the temperature sensing element 8 is connected to the temperature sensing screw hole 22 via the external thread on its protective probe, and the temperature sensing probe of the temperature sensing element 8 is inserted deep into the temperature sensing screw hole 22. In this embodiment, the temperature sensing element 8 is a resistance temperature detector (RTD) sensor, which is a commonly used temperature measuring device in the art.

[0023] As attached Figure 4 As shown, threaded holes 61 are provided on both sides of the roller 6, and the threaded holes 61 are arranged in a ring. The threaded holes 61 and the roller 6 are concentrically arranged, and the number of threaded holes 61 is 6-12. The end cap 3 is provided with a threaded hole 1 that matches the threaded holes 61. Marking bolts 4 pass through the threaded hole 1 and the threaded hole 61 to fix the roller 6 and the end cap 3. The number of marking bolts 4 is determined according to the number of threaded holes 61 on the roller.

[0024] As attached Figure 1 As shown, the two ends of the intermediate shaft 2 are provided with milled flat pressure plate end faces. A movable pressure plate 13 is provided on the upper part of the pressure plate end face. The movable pressure plate 13 is provided with two openings. Pressure plate bolts are provided at the openings of the movable pressure plate 13. The movable pressure plate 13 is fixed to the upper end of the side support plate 12 of the support 1 by pressure plate bolts.

[0025] The working principle of this invention is as follows: When the dewatering machine is running, it requires support rollers to support the force and ensure smooth rotation. Due to the significant weight of the dewatering machine, and the inevitable damage to the support rollers during long-term operation, damage can occur. Damaged support rollers can cause changes in rotation speed or stoppage, or abnormal increases in bearing temperature. The proximity switch 9 and temperature sensing element 8 on the support roller collect similar data, which is compared by a PLC program. When a significant difference occurs over a prolonged period, it can promptly provide feedback to the computer screen, prompting the operator to locate the cause of the faulty support roller and the data discrepancy. This facilitates timely troubleshooting and ensures production operation. It enables accurate and timely diagnosis of support roller faults, preventing minor anomalies from being overlooked and causing downtime that affects production progress. It also facilitates timely troubleshooting and maintenance, while saving manpower from frequent entry into confined spaces, ensuring safety.

[0026] Additionally, when the dehydrator's drum leaks, the high-temperature liquid inside the drum may flow onto the support rollers at the bottom of the drum and enter the intermediate shaft through the gaps in the support rollers. In this case, the PLC program detects an abnormal temperature in the intermediate shaft via temperature sensing element 8, prompting the operator to inspect the equipment. This invention not only detects the support rollers but also detects whether the drum is leaking.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
