Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a roller wear experimental device. Background Art

[0002] Rollers are a kind of mechanical parts and an important part of belt conveyors. There are many types and large quantities of rollers, which can support the weight of conveyor belts and materials. It accounts for 35% of the total cost of a belt conveyor and generates more than 70% of the resistance, so the quality of rollers is particularly important. Rollers are composed of wheels, bearings and shells. Their main function is to support and turn heavy objects to make them easier to move. In belt conveyors, rollers are an important part used to support the weight of conveyor belts and materials. Their quality has a vital impact on the performance and life of the conveyor.

[0003] After the roller is manufactured, it needs to undergo a wear test. The roller wear test is a test used to evaluate the wear resistance of the roller. The main purpose of this test is to simulate the wear of the roller in the actual working process, and to evaluate the wear resistance and service life of the roller by measuring and analyzing the wear amount, wear rate and other related parameters.

[0004] Wear tests are usually carried out using roller test benches. During the test, a certain load is applied to the roller through a loading device, and the roller is driven to rotate through a transmission device. During the test, the measurement and control system monitors and records various parameters in real time for subsequent data processing and analysis. By comparing the test results under different loads, speeds and other conditions, the performance indicators of the roller can be evaluated, thereby providing a scientific basis for the material selection, design and manufacturing process of the roller. A vernier caliper is usually used to measure the roller size parameters to detect the degree of wear of the roller. However, in this process, it is necessary to manually place the vernier caliper at the roller wear test position, and then observe and record the readings. The measurement is not fast enough, and for rollers of different diameters, vernier calipers of different specifications need to be replaced for measurement. The measurement is not convenient enough, which affects the efficiency of the experiment. Therefore, there is an urgent need for a roller wear test device that can quickly and accurately measure rollers and can be used for rollers of different diameters. Utility Model Content

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] like Figures 1 to 7 As shown, a roller wear test device includes a test bench 3, on the upper side of which are mounted two sets of clamping frames 1 for fixing rollers, and a measuring mechanism 2 is provided on the test bench 3 between the two sets of clamping frames 1.

[0030] The measuring mechanism 2 includes an adjusting component 21, a supporting plate 22, a plate 23, a measuring scale plate 24, a limiting groove 27 and a positioning component 28. The supporting plate 22 is fixed on the test bench 3 through the adjusting component 21. A limiting groove 27 of a T-shaped structure for accommodating the measuring scale plate 24 is provided inside the supporting plate 22. The measuring scale plate 24 has a T-shaped cross-section and is inserted inside the limiting groove 27. A plate 23 of a horizontal structure is fixed on the top of the measuring scale plate 24. A positioning component 28 is provided on the rear side of the supporting plate 22. This design solves the problem that during the roller wear test, the vernier caliper needs to be manually placed in the roller wear test position, and then the readings are observed and recorded, the measurement is not fast enough, and for rollers of different diameters, vernier calipers of different specifications need to be replaced for measurement, the measurement is not convenient enough, and the experimental efficiency is affected.

[0031] The adjustment component 21 includes a slide bar 211, a No. 1 slide groove 212, a limit slider 213 and a sleeve 216. The slide bar 211 is fixed on the test bench 3. The sleeve 216 is fixed on the bottom of the support plate 22 and sleeved on the slide bar 211. The lower side of the annular surface of the sleeve 216 is fixedly connected to the limit slider 213. The No. 1 slide groove 212 for accommodating the slider is provided inside the test bench 3. The adjustment component 21 is set to facilitate the sliding adjustment of the position of the measuring scale plate 24, and can change the corresponding position of the measuring scale plate 24 and the roller, which provides convenience for measuring rollers of different lengths and diameters. When it is necessary to move the support plate 22, the experimenter can apply force to move the support plate 22 along the slide bar 211. In this process, the sleeve 216 slides on the slide bar 211, and the limit slider 213 moves in the No. 1 slide groove 212 to ensure the stability of the support plate 22 and the accuracy of movement. This design allows the experimenter to easily adjust the position of the support plate 22 to accommodate rollers of different lengths and diameters, thereby performing accurate wear measurements.

[0032] A slot 214 is provided on the front side of the annular surface of the slide bar 211, and a fastening screw 215 is threadedly assembled on the front side of the annular surface of the slide sleeve 216, and the tail end of the fastening screw 215 is inserted into the slot 214. This design provides a positioning function for the sliding of the slide sleeve 216 through the slot 214 and the fastening screw 215, thereby improving the stability of the device. After adjusting the support plate 22 to the desired position, the experimenter tightens the fastening screw 215 so that the tail end is inserted into the slot 214, and the slide sleeve 216 is fixed in the current position, thereby firmly locking the support plate 22 at a specific position on the slide bar 211.

[0033] The surface of the measuring scale plate 24 is engraved with scale lines 221, and the left and right sides of the front surface of the supporting upright plate 22 are both horizontally engraved with indicator lines 241. The scale lines 221 and the indicator lines 241 allow the experimenter to directly read the wear amount or the diameter change of the roller, and then by comparing the scale readings before and after wear, the wear amount of the roller can be accurately calculated.

[0034] A second slide groove 25 is provided on the right side of the support vertical plate 22, and a sliding handle 26 is provided inside the second slide groove 25 and is fixedly connected to the measuring scale plate 24. This design provides an adjustment function for the measuring scale plate 24, facilitates the driving of the measuring scale plate 24 to move up and down, and improves the convenience of operation. The experimenter can adjust the position of the measuring scale plate 24 by moving the sliding handle 26 to ensure that the sticking plate 23 on the top of the measuring scale plate 24 is in contact with the surface of the roller.

[0035] The positioning assembly 28 includes a No. 3 slide groove 281, a left card plate 282, a right card plate 283, an adjusting rod 285, a connecting rod 286 and a rod groove 289. The No. 3 slide groove 281 is opened on the left side surface of the supporting vertical plate 22. An adjusting rod 285 is longitudinally and movably arranged inside the supporting vertical plate 22 and the measuring scale plate 24, and the right end of the adjusting rod 285 extends out from the inside of the sliding handle 26. The left end of the adjusting rod 285 is fixedly connected to the left card plate 282, and the rear side of the sliding handle 26 is fixedly connected to the right card plate 283. Two groups of rod grooves 289 are opened in the right card plate 283. Two groups of connecting rods 286 are fixedly arranged on the end surface of the left card plate 282 and extend into the two groups of rod grooves 289 respectively. The part of the connecting rod 286 located inside the rod groove 289 is sleeved with a return spring 287, and a blocking piece 288 is fixedly arranged at the end of the connecting rod 286. The positioning assembly 28 can be arranged to position the measuring scale plate 24 after adjustment, so that it is fixed in the current position, thereby ensuring the stability of the measuring scale plate 24 and improving the convenience of measurement. When the measuring scale plate 24 needs to be moved, the connecting rod 286 is pressed downward, and the left clamping plate 282 is driven to move outward by the connecting rod 286, so that the left clamping plate 282 is separated from the supporting vertical plate 22, and then the measuring scale plate 24 is adjusted to a proper position, and the connecting rod 286 is released, and the left clamping plate 282 returns to its original position under the reverse elastic force of the reset spring 287. The reverse elastic force of the reset spring 287 makes the left clamping plate 282 and the right clamping plate 283 interact with each other and stick to the supporting vertical plate 22, forming a stable clamping force, thereby firmly fixing the measuring scale plate 24 in the current position.

[0036] The right card plate 283 and the left card plate 282 are both L-shaped structures. The right card plate 283 and the left card plate 282 are closed to form a C-shaped structure. This structure allows the card plate to fit tightly with the measuring scale plate 24 to provide stable support and positioning. A layer of rubber pad 284 is pasted on the fitting surface of the left card plate 282 and the left side of the supporting vertical plate 22. The rubber pad 284 increases the friction and plays an anti-skid role, so that the left card plate 282 can fit more stably on the supporting vertical plate 22. At the same time, it plays a buffering role, which can prevent the left card plate 282 from directly contacting the supporting vertical plate 22 and causing wear.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
