Description

Technical Field

[0001] The present application belongs to the technical field of conveying equipment, and specifically relates to a roller test platform. Background Art

[0002] In coal mining, belt conveyors are often used for conveying coal and rock. These conveyors primarily consist of a drive unit, a drive roller, a driven roller, and a surface-adding roller. The roller is the component subject to the greatest stress and has the highest failure rate. Currently, most manufacturers only conduct static inspections of rollers before delivering them to end users. This inspection is based solely on static inspections of the roller surface, thickness, and other static indicators. Dynamic performance during operation is not verified, making roller quality uncertain. While static inspections are convenient, they fail to guarantee the quality of the roller bearings or the roller's operational performance under load. Because static inspections are often limited to static inspections, quality issues often go undetected. Failures often occur after installation due to roller quality issues. Replacement can take anywhere from one to two days to five to seven days, resulting in significant labor and material investment, and even more significant shipping losses after production halts.

[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] Before describing the various embodiments of this application in detail, we first briefly describe the technical concept of this application: Currently, the rollers of belt conveyors are all statically inspected, making it difficult to detect roller quality problems. To this end, this application provides a roller testing platform. A drive roller base and a test roller base are arranged on a bottom plate. The position of the test roller base is adjusted using a drive mechanism, thereby adjusting the distance between the test roller and the drive roller. This allows for dynamic testing of the roller, thereby more comprehensively verifying the performance and quality of the roller. The specific principles of this roller testing platform will be described below in conjunction with more embodiments.

[0025] Specifically, if Figure 1 As shown, the roller test platform of this embodiment includes a base plate 10, a driving roller base 20, a test roller base 30, and a driving mechanism 40. The driving roller base 20 is mounted on the base plate 10 and is used to support the driving roller 100. The test roller base 30 is movably mounted on the base plate 10 and is used to support the test roller 200. The driving mechanism 40 is mounted on the base plate 10 and is used to drive the test roller base 30 away from or toward the driving roller base 20 along the radial direction of the test roller 200. The driving roller 100 serves as the active roller, and the test roller 200 serves as the driven roller. The driving roller 100 and the test roller 200 are in contact with each other, and the friction between the rollers drives the test roller 200 to roll.

[0026] In one or more embodiments, there are two sets of test roller bases 30 and drive mechanisms 40. The two sets of test roller bases 30 and drive mechanisms 40 are installed on both sides of the drive roller base 20 along the radial direction of the test roller 200. In this way, the test rollers 200 can be installed on both sides of the drive roller 100 and driven to roll simultaneously to conduct dynamic testing. Of course, as needed, the test roller 200 can also be installed on only one of the test roller bases 30 to conduct dynamic testing. During testing, a certain number of temperature and vibration sensors (at least one set per bearing seat) are installed on the bearing seats of the drive roller 100 and the test roller 200. Abnormal temperature and vibration values ​​indicate a problem with the roller quality.

[0027] In one or more embodiments, the drive mechanism 40 includes a slide 41 and a drive unit 42. The test roller base 30 is mounted on the slide 41, which is slidably mounted on the bottom plate 10. The drive unit 42 is used to drive the slide 41 away from or toward the drive roller base 20 along the radial direction of the test roller 200. Exemplarily, the drive unit 42 is an electro-hydraulic push rod. The bottom plate 10 is provided with a rear bracket 11, and the slide 41 is provided with a front bracket 411. The main body of the electro-hydraulic push rod is mounted on the rear bracket 11, and the telescopic push rod of the electro-hydraulic push rod is connected to the front bracket 411 to push the slide 41 to slide, thereby driving the test roller base 30 away from or toward the drive roller base 20. This allows test rollers 200 of different diameters to achieve good contact with the drive roller 100 for rolling testing. Exemplarily, there can be two sets of drive units 42 to ensure stable drive of the slide 41.

[0028] For example, the base plate 10 is provided with a pair of spaced first slideways 12, and the slide plate 41 is slidably mounted between the pair of first slideways 12. Under the premise of enabling the slide plate 41 to slide, the limiting effect of the first slideway 12 can ensure that the slide plate 41 slides along the radial direction of the test drum 200, preventing deviation. Furthermore, the first slideway 12 is provided with a first top screw 13, which is used to abut the slide plate 41. The first top screw 13 is movably inserted into the first slideway 13. When the position of the slide plate 41 needs to be adjusted, the first top screw 12 is loosened. When the position of the slide plate 41 is adjusted, the first top screw 13 is tightened to achieve the positioning of the slide plate 41.

[0029] In one or more embodiments, the test roller base 30 is slidably mounted on the slide plate. The sliding direction of the test roller base 30 relative to the slide plate 41 is the axial direction of the test roller 200. For test rollers 200 of different lengths, the test roller base 30 is provided with the ability to adjust its position in the axial direction to ensure that test rollers 200 of different lengths can all effectively contact the drive roller 100. Exemplarily, the test roller base 30 includes two first sub-bases spaced apart along the axial direction of the test roller 200. The two first sub-bases are respectively used to support the two ends of the test roller 200. The test rollers 200 of different lengths can be accommodated by adjusting the relative distance between the two first sub-bases.

[0030] Exemplarily, the slide 41 is provided with a pair of spaced-apart second slideways 44, and the bottoms of the two first sub-bases are slidably mounted between the pair of second slideways 44. Thus, while the first sub-bases can slide, the limiting action of the second slideways 44 ensures that the first sub-bases slide along the axial direction of the test drum 200, preventing deviation. Exemplarily, the second slideway 44 is provided with a second top screw 43, which is used to abut the bottoms of the two first sub-bases. The second top screw 43 is movably inserted into the second slideway 44. When the position of the first sub-base needs to be adjusted, the second top screw 43 is loosened. When the position adjustment is completed, the second top screw 43 is tightened to achieve the positioning of the first sub-base.

[0031] In one or more embodiments, the driving roller base 20 includes two second sub-bases spaced apart along the axial direction of the driving roller 100, and the two second sub-bases are respectively used to support the two ends of the driving roller 100, wherein the axial direction of the driving roller 100 is parallel to the axial direction of the test roller 200.

[0032] The roller test platform provided in this embodiment can use a driving roller to drive test rollers of different diameters to perform rolling experiments, and can verify the performance of the roller under various conditions, such as high temperature, low temperature, high speed, heavy load, etc., to test the reliability of the roller in various environments.

[0033] The above describes in detail the specific implementation methods of the present application. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principles and spirit of the present application, the scope of which is defined by the claims and their equivalents. These modifications and improvements should also be within the scope of protection of the present application.
