Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, specifically to a conveyor testing device. Background Technology

[0002] Belt conveyors are widely used in industrial and mining enterprises. Idler rollers are crucial components of belt conveyors, coming in various types and in large quantities. They are the most frequently used and replaced parts of belt conveyors, making their service life extremely important. In underground environments, belt conveyors are frequently exposed to water. If the idler rollers have poor waterproofing, water can enter and corrode bearings and other sensitive components, reducing their lifespan. Therefore, it is necessary to test the waterproofing performance of idler rollers. However, current testing equipment lacks the capability to assess the waterproofing performance of idler rollers. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, this invention provides a conveyor testing device that can test the waterproof performance of idlers.

[0005] The conveyor testing apparatus according to an embodiment of the present invention includes: a water tank defining an immersion area for holding water; a mounting frame including a first frame and a roller mounting portion, the roller mounting portion being disposed on the first frame and corresponding to the immersion area, the first frame being connected to the water tank, at least a portion of the first frame being movable in the vertical direction so that the roller cooperating with the roller mounting portion comes into contact with the water in the immersion area; a pulley assembly and a driver, the pulley assembly including a driven pulley, a driving pulley and a conveyor belt, the mounting frame further including a driver mounting portion and a driven pulley mounting portion, the driven pulley mounting portion and the driven pulley mounting portion being installed... All components are mounted on the first frame. The driven pulley mounting portion, the idler roller mounting portion, and the driver mounting portion are spaced apart along the length of the first frame. The idler roller mounting portion is located between the driven pulley mounting portion and the driver mounting portion. A portion of the driven pulley mounting portion is rotatable relative to the first frame. The driven pulley is fitted onto this portion of the driven pulley mounting portion. The driver is mounted on the driver mounting portion. The driving pulley is fitted onto the driver so that the driver drives the driving pulley to rotate. The conveyor belt is wound around the driven pulley and the driving pulley. The conveyor belt is able to contact the idler roller fitted onto the idler roller mounting portion.

[0006] The conveyor testing apparatus of this invention immerses the idler roller in water in the immersion zone by attaching the idler roller to the idler roller mounting part and lowering at least a portion of the first frame. The idler roller is then rotated by the drive of the conveyor belt, simulating the rotation state of the idler roller under actual working conditions, the deformation state of the idler roller under the pressure of the conveyor belt, and the heat generation state due to friction. Therefore, the conveyor testing apparatus of this invention can not only test the waterproof performance of the idler roller, but also provide more accurate experimental results.

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The conveyor test apparatus 100 of the present invention is described below with reference to the accompanying drawings.

[0031] like Figures 1-6 As shown, the conveyor testing device 100 of this embodiment includes a water tank 1, a mounting frame 2, a pulley assembly 3, and a driver 4.

[0032] The water tank 1 defines an immersion area 10 for holding water. The mounting frame 2 includes a first frame 21 and a roller mounting part 23. The roller mounting part 23 is disposed on the first frame 21 and corresponds to the immersion area 10. The first frame 21 is connected to the water tank 1. At least a portion of the first frame 21 is movable in the vertical direction so that the roller 200 that cooperates with the roller mounting part 23 comes into contact with the water in the immersion area 10.

[0033] The pulley assembly 3 includes a driven pulley 32, a driving pulley 33, and a conveyor belt 31. The mounting frame 2 also includes a driver 4 mounting portion and a driven pulley mounting portion 22, both of which are mounted on the first frame 21. The driven pulley mounting portion 22, the idler roller mounting portion 23, and the driver 4 mounting portion are spaced apart along the length of the first frame 21, with the idler roller mounting portion 23 located between the driven pulley mounting portion 22 and the driver 4 mounting portion. A portion of the driven pulley mounting portion 22 is rotatable relative to the first frame 21, and the driven pulley 32 engages with this portion of the driven pulley mounting portion 22. In other words, this portion of the driven pulley mounting portion 22 that engages with the driven pulley 32 is rotatable relative to the first frame 21, allowing the driven pulley 32 to rotate and ensuring that the driven pulley 32 does not obstruct the movement of the conveyor belt 31. The driver 4 is mounted on the driver 4 mounting part, and the drive pulley 33 cooperates with the driver 4 so that the driver 4 drives the drive pulley 33 to rotate. The conveyor belt 31 is wrapped around the driven pulley 32 and the drive pulley 33, and the conveyor belt 31 can contact the idler 200 that is fitted on the idler mounting part 23.

[0034] The specific implementation process of the conveyor testing device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0035] The shaft of the idler roller 200 is fitted onto the idler roller mounting part 23, so that the outer circumferential surface of the idler roller 200 contacts the conveyor belt 31. The driver 4 is started to rotate the drive pulley 33, which drives the conveyor belt 31 to rotate. The drive pulley 33 and the driven pulley 32 keep the conveyor belt 31 taut, so that the conveyor belt 31 can apply sufficient friction to the idler roller 200 to drive the idler roller 200 to rotate. At least a portion of the first frame 21 is moved downward, so that the idler roller 200 enters the immersion zone 10 and comes into contact with water, thereby conducting an immersion test on the idler roller 200. After the idler roller 200 has been immersed in water for a certain period of time, the driver 4 is stopped, and at least a portion of the first frame 21 is moved upward to remove the idler roller 200 from the immersion zone 10. The idler roller 200 is then removed from the idler roller mounting part 23, and the water ingress of the idler roller 200 is observed, thereby completing the waterproof performance test of the idler roller 200.

[0036] The conveyor testing apparatus 100 of this embodiment of the invention immerses the idler roller 200 in the water of the immersion zone 10 by mounting the idler roller 200 on the idler roller mounting part 23 and lowering at least a portion of the first frame 21. The idler roller 200 is then rotated by the drive of the conveyor belt 31, simulating the rotation state of the idler roller 200 under actual working conditions, the deformation state of the idler roller 200 under the pressure of the conveyor belt 31, and the heating state after friction. Therefore, the conveyor testing apparatus 100 of this embodiment of the invention can not only test the waterproof performance of the idler roller 200, but also provide more accurate experimental results.

[0037] Therefore, the conveyor testing device 100 of this embodiment of the invention can test the waterproof performance of the idler roller 200, and the test results are more accurate.

[0038] like Figures 1-6 As shown, the conveyor testing device 100 of this embodiment includes a water tank 1, a mounting frame 2, a pulley assembly 3, and a driver 4.

[0039] In some embodiments, the driver 4 is an electric motor, and the drive pulley 33 includes a second shaft hole. The shaft of the electric motor is engaged with the second shaft hole, thereby causing the driver 4 to drive the drive pulley 33 to rotate.

[0040] In some embodiments, the water tank 1 includes a surrounding wall 11 and a bottom wall 12, with the bottom wall 12 connected to the lower end of the surrounding wall 11. The surrounding wall 11 and the bottom wall 12 define an immersion area 10. The water tank 1 also includes a guide rail disposed on the inner wall surface of the surrounding wall 11, with the guide rail extending in the same direction as the vertical direction. A guide member is provided on the first frame 21, which cooperates with the guide rail to allow the mounting frame 2 to move vertically. In other words, by cooperating with the guide member on the first frame 21 and the guide rail, the first frame 21 can move vertically as a whole, allowing the idler roller 200 fitted on the idler roller mounting part 23 to be immersed in the water of the immersion area 10. This design is not only simple in structure but also convenient for users to operate.

[0041] In some embodiments, such as Figures 1-2 As shown, the water tank 1 includes a surrounding wall 11, a bottom wall 12, and a second frame 13. The bottom wall 12 is connected to the lower end of the surrounding wall 11. The surrounding wall 11 and the bottom wall 12 define an immersion area 10. The second frame 13 is located at the upper end of the surrounding wall 11 and has a first through hole 131. The mounting frame 2 also includes a first rotating shaft 24. The first frame 21 has a second through hole 211 located between the roller mounting part 23 and the driver 4 mounting part. The first rotating shaft 24 is fitted into the first through hole 131 and the second through hole 211 so that the mounting frame 2 can rotate relative to the second frame 13.

[0042] In other words, by rotating the first frame 21 relative to the second frame 13, the portion of the first frame 21 having the idler roller mounting portion 23 and the driven pulley mounting portion 22 moves vertically, allowing the idler roller 200 fitted on the idler roller mounting portion 23 to be immersed in the water of the immersion area 10. This not only simplifies the structure but also facilitates operation. Furthermore, since the second through hole 211 is located between the idler roller mounting portion 23 and the driver 4 mounting portion, when the first frame 21 rotates relative to the second frame 13 and the idler roller mounting portion 23 moves downward, the driver 4 mounting portion moves upward, preventing the driver 4 from being immersed in water. Therefore, there is no need to provide an additional waterproof structure for the driver 4, reducing manufacturing costs.

[0043] In some embodiments, such as Figures 1-3 As shown, the first frame 21 is provided with a first insertion hole 213, and there are multiple first insertion holes 213, which are spaced apart circumferentially in the first through hole 131. The second frame 13 is also provided with a second insertion hole, which corresponds to the first insertion hole 213 circumferentially in the first through hole 131. The mounting frame 2 also includes a connector 25, which can fit into the first insertion hole 213 and the second insertion hole. In other words, when the idler roller 200 is immersed in the water of the immersion area 10, the connector 25 is inserted into the second insertion hole and into one of the multiple first insertion holes 213 corresponding to the second insertion hole, thereby fixing the position of the first frame 21 and keeping the idler roller 200 immersed in the water of the immersion area 10, which facilitates operation by the user and improves the practicality of the conveyor testing device 100 of this embodiment of the invention.

[0044] In some embodiments, such as Figures 1-2 As shown, the connector 25 includes a first segment and a second segment opposite each other in its length direction, with the radial dimension of the second segment being larger than that of the first segment. The mounting bracket 2 also includes an elastic element, one end of which is connected to the second bracket 13, and the other end of which is connected to the second segment. In other words, the radial dimension of the second segment is larger than that of the first segment, forming a step between the second and first segments. The elastic element is connected at one end to the second bracket 13, and at the other end to the kick surface of the second segment. Thus, the elastic force provided by the elastic element prevents the connector 25 from easily dislodging from the first and second insertion holes 213, thereby improving the stability of the fixation between the first and second brackets 21 and 13.

[0045] In some embodiments, such as Figures 5-6As shown, the driven pulley mounting part 22 includes a second rotating shaft 221, a fixed cylinder 222, and a bearing 223. The bearing 223 is disposed in the fixed cylinder 222, and its outer peripheral surface contacts the inner peripheral surface of the fixed cylinder 222. A portion of the second rotating shaft 221 is inserted into the bearing 223, and the outer surface of this portion of the second rotating shaft 221 contacts the inner peripheral surface of the bearing 223. The other portion of the second rotating shaft 221 mates with the driven pulley 32.

[0046] Specifically, the driven pulley 32 has a first shaft hole, the rear end of which is inserted into the bearing 223, and the front end of which fits into the first shaft hole. When the conveyor belt 31 rotates, the driven pulley 32 can rotate with the conveyor belt 31, enabling the conveyor belt 31 to move normally. It has a simple structure and low manufacturing cost.

[0047] In some embodiments, such as Figures 5-6 As shown, the fixed cylinder 222 also includes a cylinder body 2221 and a first sliding plate 2222. The cylinder body 2221 is connected to the first sliding plate 2222. The bearing 223 is disposed in the cylinder body 2221, and the outer peripheral surface of the bearing 223 is in contact with the inner peripheral surface of the cylinder body 2221. The mounting bracket 2 also includes a first guide member 212. The first sliding plate 2222 is provided with a first guide hole 22221. The extending direction of the first guide hole 22221 is consistent with the length direction of the first bracket 21. The first guide member 212 is connected to the first bracket 21, and the first guide member 212 fits in the first guide hole 22221 so that the fixed cylinder 222 can move in the length direction of the first bracket 21.

[0048] In other words, the fixed cylinder 222 cooperates with the first guide member 212 on the first frame 21 through the first sliding plate 2222, so that the fixed cylinder 222 can move relative to the first frame 21 in the length direction of the first frame 21, thereby adjusting the interval between the driven pulley 32 and the driving pulley 33 to adjust the tension of the conveyor belt 31, thereby simulating the tension state of the conveyor belt 31 under different actual working conditions, making the test results more accurate.

[0049] Furthermore, the first guide member 212 includes a first bolt and a first nut, wherein the first bolt is connected to the first frame 21 and can engage with the first nut. The first bolt is inserted into the first guide hole 22221. After adjusting the gap between the driven pulley 32 and the driving pulley 33, the first sliding plate 2222 is pressed onto the first frame 21 by engaging the first nut with the first bolt, thereby fixing the driven pulley 32.

[0050] In some embodiments, such as Figures 5-6As shown, the idler roller mounting part 23 includes a first clamping member 231 and a second clamping member 232. Both the first clamping member 231 and the second clamping member 232 are connected to the first frame 21, and the first clamping member 231 and the second clamping member 232 are opposite each other in the vertical direction, and one of the first clamping member 231 and the second clamping member 232 is movable in the vertical direction. In other words, the first clamping member 231 is movable in the vertical direction; or, the second clamping member 232 is movable in the vertical direction; or, both the first clamping member 231 and the second clamping member 232 are movable in the vertical direction. Thus, by adjusting the interval between the first clamping member 231 and the second clamping member 232, the first clamping member 231 and the second clamping member 232 can clamp the rotating shaft of the idler roller 200, which not only has a simple structure, but also has a good fixing effect on the rotating shaft of the idler roller 200.

[0051] The second clamping member 232 has a groove on its end face adjacent to one end of the first clamping member 231 in the vertical direction, and the groove is adapted to the rotating shaft of the idler roller 200. Alternatively, the first clamping member 231 has a second groove on its end face adjacent to one end of the second clamping member 232 in the vertical direction, and the second groove is adapted to the rotating shaft of the idler roller 200. In other words, the second clamping member 232 has a groove on its end face adjacent to one end of the first clamping member 231 in the vertical direction; or, the first clamping member 231 has a second groove on its end face adjacent to one end of the second clamping member 232 in the vertical direction; or, the second clamping member 232 has a groove on its end face adjacent to one end of the first clamping member 231 in the vertical direction, the groove is adapted to the rotating shaft of the idler roller 200, and the first clamping member 231 has a second groove on its end face adjacent to one end of the second clamping member 232 in the vertical direction. This further improves the fixing effect of the first clamping member 231 and the second clamping member 232 on the rotating shaft of the idler roller 200.

[0052] For example Figure 6 As shown, a V-shaped groove is provided on the lower end surface of the first clamping member 231, and a V-shaped groove is provided on the upper end surface of the second clamping member 232.

[0053] In some embodiments, such as Figures 5-6As shown, the idler roller mounting part 23 also includes a fixing frame 233 and a guide rod 234. The fixing frame 233 includes a first side plate 2331, a second side plate 2332, a top plate 2333, and a back plate 2334. The first side plate 2331 and the second side plate 2332 are opposite each other in the length direction of the first frame 21. The top plate 2333, the first side plate 2331, and the second side plate 2332 are all connected to the back plate 2334. The top plate 2333 is connected to the upper end of the first side plate 2331 and the upper end of the second side plate 2332. The top plate 2333 is provided with a third through hole 23331. The guide rod 234 passes through the third through hole 23331 and is connected to the first clamping member 231. This facilitates the user to move the first clamping member 231 through the guide rod 234, thus improving the practicality of the conveyor testing device 100 of this embodiment of the invention.

[0054] In some embodiments, such as Figures 5-6 As shown, the mounting frame 2 also includes a second guide member, which is connected to the first frame 21. The back plate 2334 is provided with a second guide hole 23341. The extension direction of the second guide hole 23341 is consistent with the first direction, which is perpendicular to the length direction of the first frame 21. The second guide member is fitted in the second guide hole 23341 so that the roller mounting part 23 can move in the vertical direction.

[0055] In other words, the idler roller mounting part 23 cooperates with the second guide member on the first frame 21 through the back plate 2334, allowing the fixed cylinder 222 to move relative to the first frame 21 in a first direction, thereby adjusting the spacing between the idler roller 200 and the conveyor belt 31. When the radial dimension of the idler roller 200 changes, the position of the idler roller 200 can be adjusted by adjusting the position of the idler roller mounting part 23, so that the idler roller 200 can contact the conveyor belt 31. Thus, the conveyor testing device 100 of this embodiment can be adapted to idler rollers 200 with different radial dimensions, thereby improving the universality of the conveyor testing device 100 of this embodiment.

[0056] Furthermore, the second guide member includes a second bolt and a second nut, wherein the second bolt is connected to the second frame 13 and can engage with the second nut. The second bolt is inserted into the second guide hole 23341. After adjusting the gap between the idler roller 200 and the conveyor belt 31, the back plate 2334 is pressed onto the first frame 21 by engaging the second nut with the second bolt, thereby fixing the idler roller mounting part 23.
