Description

Wear testing equipment and wear performance testing method for conveyor chain rollers Technical Field

[0001] The present invention relates to the field of chain processing, and in particular to wear testing equipment and a wear performance detection method for conveying chain rollers. Background Art

[0002] A conveyor chain is a mechanical device used to transport items. It consists of inner links, outer links, and rollers, with the inner links connected in series via the outer links. As shown in Figure 1, the inner links consist of two inner links, with a sleeve positioned between them. The rollers are mounted on this sleeve. Due to the operating mode of the conveyor chain, the diameter of the rollers is larger than the width of the inner and outer links. During operation, the rollers contact and roll along the guide rails of the equipment, thereby carrying and conveying materials. Technical issues

[0003] The rolling performance of the rollers on the guide rails is crucial during the operation of a conveyor chain. A common failure mode is wear and tear between the rollers and the sleeves. Once the wear between the rollers and the sleeves is excessive, the clearance between the two will increase, making it easy for debris to enter. Over time, the rollers will become stuck, significantly increasing the tension of the chain, causing the chain to stretch rapidly and even causing it to break instantly. At the same time, wear and tear between the rollers and the sleeves can also cause uneven chain force, increased vibration, and poor operation.

[0004] Therefore, it is necessary to test the wear performance between the roller and the bushing to obtain the chain's performance and service life parameters. The conventional test method uses an entire chain to simulate the operating conditions of a conveyor chain and conduct a conveyor operation test. This has the advantage of reliable test results, but the equipment required for this test method is complex, takes up a lot of space, and is inefficient.

[0005] The purpose of this application is to design a method for measuring the wear performance of rollers and sleeves to address the above-mentioned problems of existing test methods, simplify the equipment structure, and improve test efficiency. Technical Solutions

[0052] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] Example

[0054] As shown in FIG2 and FIG3 , a wear test device for conveying chain rollers includes a mounting module 3 , a driving module 1 , a pressing module 2 , a loading module 4 and a detection module.

[0055] As shown in Figures 3-5, the mounting module 3 includes a mounting base, on which two load-bearing wheels 33 are rotatably connected. The two load-bearing wheels 33 are arranged in parallel and are connected to the mounting base via a rotating shaft. One of the two load-bearing wheels 33 is a driving wheel, and the other is a driven wheel. A synchronization component 6 is provided between the driving wheel and the driven wheel. The synchronization component 6 is a synchronous belt. When connected by the synchronous belt, the driving wheel and the driven wheel rotate synchronously in the same direction. The mounting module 3 is used to install, load, and limit the test piece 7 composed of an inner chain link and rollers, wherein the rollers are placed on the two load-bearing wheels 33.

[0056] As shown in Figures 4 and 5, the mounting base includes a base plate 34 and two support units 31. The two support units 31 are arranged in parallel, forming a test space between them. The load-bearing wheel 33 is located within the test space and connected to the support units 31 via a central axis. The two support units 31 provide reliable lateral positioning of the inner chain links, ensuring the smooth and reliable conduct of the test. Specifically, the support units 31 are vertically arranged plates.

[0057] As shown in FIG. 4 and FIG. 5 , at least one of the support units 31 is provided with an operating channel 312 , and the operating channel 312 passes through the corresponding support unit 31 .

[0058] As shown in Figures 5-8, the mounting module 3 also includes an anti-rotation limiter assembly, which includes a limiter shaft 35. The mounting base is provided with a limiter hole, which is arranged in an elongated strip. The limiter shaft 35 is disposed within the limiter hole and is removably connected to the mounting base. Due to the elongated shape of the limiter hole, the position of the limiter shaft 35 relative to the limiter block 313 can be adjusted to accommodate conveyor chains of varying specifications.

[0059] As shown in FIG. 2 and FIG. 3 , the driving module 1 is a motor. The driving module 1 is connected to the driving wheel through a coupling. The driving module 1 is used to drive the driving wheel to rotate.

[0060] As shown in Figures 6-11, the compression module 2 includes a floating compression seat 22, to which a compression wheel 21 is rotatably connected. The floating compression seat 22 is in floating connection with the mounting seat via an elastic member 24. The compression wheel 21 is positioned above the load-bearing wheels 33, with its center parallel to the center of the load-bearing wheels 33. Horizontally, the compression wheel 21 is positioned between the two load-bearing wheels 33, forming a mounting area between the compression wheel 21 and the load-bearing wheels 33.

[0061] The installation section is aligned with the operating channel 312 . During the installation operation, the staff can adjust the position of the inner chain link, insert the adapter core shaft 43 , and perform other operations through the operating channel 312 .

[0062] The pressing module 2 is used to press the roller onto the load-bearing wheel 33 to ensure that there is sufficient friction between the roller and the load-bearing wheel 33 for transmission, and the pressing wheel 21 can rotate along with the roller.

[0063] As shown in Figure 5, further, the operating channel 312 extends upward to the top of the support unit 31, and the top of the test space is open. As shown in Figures 6 to 11, the clamping module 2 also includes an adjustment seat 23 and a connecting rod 25, and the connecting rod 25 is located between the adjustment seat 23 and the floating clamping seat 22, and the elastic member 24 is located between the adjustment seat 23 and the floating clamping seat 22. The adjustment seat 23 is arranged at the top of the support unit 31 and is detachably connected to the support unit 31. The floating clamping seat 22 and the clamping wheel 21 extend into the test space. A slider 221 is provided on the floating clamping seat 22, and the slider 221 is slidably arranged in the operating channel 312.

[0064] The top opening of the test space can be used to place the inner link and roller assembly, and provides a channel for the placement and adjustment of the clamping module 2. When placing the assembly, the clamping module 2 can be removed, and after adjusting the position of the assembly, the clamping module 2 can be installed and the clamping operation can be carried out.

[0065] As shown in FIG6 to FIG11 , the loading module 4 includes a loading head 41 , a load unit 42 and an adapting mandrel 43 . The adapting mandrel 43 is connected to the loading head 41 , and the load unit 42 is hung on the loading head 41 .

[0066] The limiting shaft 35 is used to be inserted into one of the sleeves of the inner link and limited on the mounting seat. The adapting core shaft 43 is used to be inserted into the other sleeve of the inner link and limit it. Both sleeves of the inner link are limited and the installation is reliable. During operation, only the roller can rotate under the drive of the load-bearing wheel 33.

[0067] The loading module 4 is used to apply a preset load between the roller and the sleeve to simulate the gravity load of the material being conveyed when the conveyor chain is working.

[0068] As shown in Figures 4 and 5, the two support units 31 are further provided with a limiting channel 311, which passes through the corresponding support unit 31 and extends to the bottom end of the support unit 31. The support unit 31 is also provided with a limiting block 32, which is located below the installation area and corresponds to the limiting channel 311.

[0069] As shown in Figures 8-11, the loading head 41 comprises a body 411 and two connecting arms 412. The adapting mandrel 43 is detachably connected to the two connecting arms 412. The body 411 is positioned within the test space. The connecting arms 412 correspond to the support units 31 one-to-one and extend into the corresponding limiting channels 311. The limiting blocks 32 are used to limit the maximum distance that the connecting arms 412 can move downward along the limiting channels 311.

[0070] Before loading, the loading head 41 can be temporarily placed on the limit stop 32, which acts as a load-bearing and position-limiting mechanism for the loading head 41. During loading, the inner link is positioned between the two connecting arms 412, and the adapting mandrel 43 passes through the corresponding sleeve. Because the loading head 41 is applied to the adapting mandrel 43 via the two connecting arms 412, and the load cell 42 and the main body 411 of the loading head 41 can be positioned directly below the roller, unbalanced loading is effectively avoided, resulting in reliable loading and convenient operation.

[0071] As shown in Figures 2 and 3 , the detection module includes a rotational speed detection assembly 52 and a displacement detection assembly 51. The rotational speed detection assembly 52 is used to detect the rotational speeds of the load wheel 33 and the pressure wheel 21, respectively, while the displacement detection assembly 51 is used to detect the vertical displacement of the loading module 4. The detection module is used to detect operating parameters during the test, providing conditions for wear performance evaluation.

[0072] As shown in Figures 2 and 3, specifically, the speed detection assembly 52 includes a first detection unit and a second detection unit, wherein the first detection unit is disposed between the drive module 1 and the driving wheel and is used to detect the speed of the driving wheel, and the second detection unit is disposed on one of the support units 31 and is disposed toward the pressure wheel 21 and is used to detect the speed of the pressure wheel 21. When the speed difference between the driving wheel and the pressure wheel 21 reaches a certain value, it can be determined that there is slippage between the roller and the load-bearing wheel 33 or the pressure wheel 21, which may be caused by insufficient pressing force, insufficient load, etc., and the machine needs to be shut down for processing.

[0073] As shown in Figures 2 and 3, the displacement detection assembly 51 includes a displacement sensor, which is located below the load cell 42. The wear between the roller and the sleeve is fed back to the displacement sensor via the displacement of the load cell 42. When the wear between the roller and the sleeve reaches a certain value, wear failure is determined and the test is terminated.

[0074] As shown in Figures 12 and 13, to improve test efficiency, there are at least two mounting modules 3, the clamping module 2 and the loading module 4 correspond one to one with the mounting modules 3, and the driving module 1 is connected to one of the driving wheels. Multiple inner chain links can be tested simultaneously.

[0075] As shown in FIG. 12 , as a specific embodiment, the driving wheels of each mounting module 3 are aligned, and a transmission shaft 9 is provided between every two adjacent driving wheels.

[0076] As shown in FIG13 , as another specific embodiment, the installation modules 3 are arranged in parallel, and a transmission assembly 8 is provided between two adjacent installation modules 3. Specifically, the transmission assembly 8 includes a timing belt, and in two adjacent installation modules 3, the driven pulley of one transmission module is connected to the driving pulley of the other transmission module via the timing belt.

[0077] The wear test equipment of the present application can use a combination of an inner chain link and a roller as a test piece. The equipment has a simple structure and has the advantages of convenient operation, reliable operation, and high test efficiency.

[0079] At least the following steps are included:

[0080] S1. Installation: Select the inner chain link and a single roller to assemble the test piece, place the roller in the installation range, and simultaneously contact the two load-bearing wheels 33;

[0081] S2. Compression: The compression wheel 21 of the compression module 2 contacts the upper side of the roller and applies pressure to the roller, pressing the roller against the load-bearing wheel 33;

[0082] S3 loading: The adapter mandrel 43 passes through the sleeve located within the installation interval and is connected to the load unit 42 through the loading head 41, and the load size is set according to the preset test parameters;

[0083] S4. Test: The driving module 1 drives the load-bearing wheel 33 to rotate, and the load-bearing wheel 33 drives the roller to rotate relative to the sleeve; during operation, the detection module detects the rotation speed of the load-bearing wheel 33 and the pressure wheel 21, and the displacement of the loading module 4 in the vertical direction.
