AI Technical Summary

Technical Problem

Existing belt conveyor misalignment detection switches cannot accurately detect misalignment in real time and are easily affected by vibration, leading to false alarms or false alarms, and cannot quantify the misalignment value.

Method used

It adopts a combination structure of bracket, outer arc sleeve, bearing, connecting shaft, drive shaft, vertical roller and potentiometer. By squeezing the vertical roller with the edge of the belt, the rotation angle of the drive shaft is converted into angular displacement and measured by potentiometer, which reduces the impact of vibration.

Benefits of technology

It enables real-time and accurate detection of belt conveyor misalignment, reduces equipment damage, extends equipment life, and quantifies the amount of misalignment.

Description

Technical Field

[0001] This utility model relates to a belt conveyor misalignment monitoring device. Background Technology

[0002] Currently, belt conveyor misalignment detection switches are mainly two-pole misalignment switches installed on the belt conveyor idler frame. They work by rotating and pressing a detection roller to tilt the belt, triggering two sets of contacts and sending "please misalign" or "re-misalignment" signals. However, these switches suffer from problems such as inaccurate real-time detection, inability to quantify misalignment values, significant susceptibility to vibration, and a tendency to reject or false alarms. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a belt conveyor misalignment monitoring device.

[0004] The above objectives are achieved through the following technical solutions: A belt conveyor misalignment monitoring device comprises a bracket, an outer arc sleeve fixed on the bracket, a bearing fixed inside the outer arc sleeve, an inner ring of the bearing fixed to a connecting shaft, a side of the connecting shaft fixed to a transmission shaft, and a vertical roller sleeved at the bottom of the transmission shaft. The connecting shaft is sleeved at one end of the universal flexible shaft, and the other end of the universal flexible shaft is fixed to the rotating rod of the potentiometer; A spring connects the outer arc sleeve to the drive shaft.

[0005] The belt conveyor misalignment monitoring device mentioned above, wherein the vertical roller is in contact with the edge of the belt.

[0006] The belt conveyor misalignment monitoring device is described above, wherein the vertical roller is rotatably connected to the drive shaft. Beneficial effects

[0007] 1. In this utility model, the edge of the belt is pressed against the vertical roller. When the belt runs off track, the drive shaft rotates. The drive shaft is connected to a potentiometer via a universal flexible shaft, which converts the rotation angle of the drive shaft into angular displacement. The potentiometer can observe the amount of angular displacement, reduce vibration damage to the equipment, improve the equipment life, and can obtain the belt conveyor offset in real time and accurately.

[0008] Appendix Figure 1 This is the front view of this utility model; Appendix Figure 2 This is a top view of the present invention; Appendix Figure 3 It is attached Figure 1 Enlarged view of part A; Appendix Figure 4 It is attached Figure 2 Enlarged view of part B; In the diagram: 1. Potentiometer; 2. Potentiometer bracket; 3. Universal flexible shaft; 4. Connecting shaft; 5. Bearing; 6. Drive shaft; 7. Vertical roller; 8. Belt; 9. Bracket; 10. Top plate; 11. L-shaped vertical plate; 12. Opening; 13. Spring; 14. Outer arc sleeve; 15. Idler roller. Detailed Implementation

[0009] Reference Figures 1-4 A belt conveyor misalignment monitoring device comprises a support 9, a top plate 10, both ends of which are fixed to an L-shaped vertical plate 11. An outer arc sleeve 14 is fixed on the support. The outer arc sleeve is a three-quarter arc sleeve. A bearing 5 is fixed inside the outer arc sleeve. The inner ring of the bearing is fixed to a connecting shaft 4. The side of the connecting shaft is fixed to a transmission shaft 6. The transmission shaft passes through an opening 12 on a fixed plate. A vertical roller 7 is fitted at the bottom of the transmission shaft. The connecting shaft is sleeved at one end of the universal flexible shaft 3, and the other end of the universal flexible shaft is fixed to the rotating rod of the potentiometer 1; A spring 13 is connected between the outer arc sleeve and the drive shaft.

[0010] The vertical roller is in contact with the edge of the belt 8.

[0011] The vertical roller is rotatably connected to the drive shaft.

[0012] Working principle: During use, the vertical roller contacts the edge of the belt. A spring ensures that the vertical roller and the belt edge are in contact and pressed together. As the belt edge is pressed against the vertical roller, the position of the vertical roller changes, keeping it in contact with the belt edge and causing the drive shaft to rotate. The drive shaft is connected to a potentiometer via a universal flexible shaft, which converts the rotation angle of the drive shaft into angular displacement. The potentiometer can observe the amount of angular displacement, reducing vibration damage to the equipment, improving equipment lifespan, and providing real-time and accurate measurement of belt conveyor offset.
