Description

Technical Field

[0001] This utility model relates to the field of roller testing technology, and in particular to a roller loading testing device. Background Technology

[0002] In practical applications, rollers need to withstand a certain weight, such as the weight of materials on the conveyor belt or the weight of the equipment itself. Through loading tests, the working state of the rollers under different load conditions can be simulated, and their maximum load capacity can be accurately measured to ensure that the rollers will not deform, be damaged or fail due to overload in actual use. Currently, technicians directly observe the abnormal vibration, noise or deviation of the rollers to judge the working state of the rollers, but it is difficult to understand the degree of deformation of the roller surface by relying solely on the naked eye.

[0003] Therefore, it is necessary to provide a new roller loading test device to solve the above-mentioned technical problems. Utility Model Content

[0007] Preferably, the top of the base is fixed with a guide for limiting the movement path of the adjustment frame, the adjustment frame is slidably mounted on the guide, and the adjustment frame is threaded with a limiting bolt connected to the guide for stabilizing the adjustment frame.

[0008] Preferably, both the fixed plate and the adjusting plate are equipped with an electric telescopic rod, and the output rod of the electric telescopic rod is equipped with a limiting plate for stabilizing the movement path of the carrier.

[0009] Preferably, the guide frame is provided with a sliding groove, and a slider is slidably installed in the sliding groove. The slider is connected to the adjustment frame, and the bottom of the adjustment frame is inlaid with a ball bearing that contacts the top of the base to reduce friction.

[0010] Preferably, the spring is provided with a limiting telescopic rod for limiting the extension and retraction path of the spring. The limiting telescopic rod is fixed between the adjusting block and the U-shaped plate. The adjusting block is equipped with a connecting plate that is connected to the base by adjusting bolts.

[0011] Preferably, a motor box is fixed on the base, and a servo motor for driving the connecting cylinder to rotate is installed in the motor box. The output shaft of the servo motor is connected to the connecting cylinder located on the fixed plate through a coupling.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-4 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the roller loading test device provided by this utility model; Figure 2 This is a schematic diagram of the assembly structure of the adjusting block, spring, U-shaped plate and adjusting cylinder in this utility model; Figure 3 This is a side view of the adjustment frame in this utility model. Figure 4 This is a three-dimensional structural diagram of the connecting cylinder in this utility model.

[0023] The roller loading test device includes: a base 1; an adjusting block 9 detachably mounted on the base 1; a spring 10 mounted on the adjusting block 9; a U-shaped plate 11 fixed on the spring 10, on which an adjusting cylinder 12 that can contact the test roller is mounted; a connecting rod 13 fixed on the U-shaped plate 11, on which a reading head 14 is provided; a grating 15 disposed on the adjusting block 9, the grating 15 being able to contact the reading head 14 for detecting the displacement distance of the adjusting cylinder 12; and a device disposed on the base 1 for stabilizing the roller. The fixed structure allows for flexible adjustment of the position by setting the adjustment block 9, making it easy to adapt to rollers of different specifications and improving the versatility of the device. The spring 10 installed on the adjustment block 9, in conjunction with the U-shaped plate 11 and the adjustment cylinder 12, can detect the degree of deformation of the roller. In conjunction with the connecting rod 13 and its reading head 14 fixed on the U-shaped plate 11, and the grating 15 on the adjustment block 9, the degree of deformation of the roller surface can be intuitively reflected by detecting the displacement distance of the adjustment cylinder 12, making up for the deficiencies of visual observation. By setting the fixed structure, the roller is ensured to be stable during the test, avoiding the impact of shaking on the test results.

[0024] The fixing structure includes a fixing plate 2 fixed to the top of the base 1, an adjusting frame 3 movably mounted on the base 1, an adjusting plate 4 fixed to the top of the adjusting frame 3, connecting cylinders 5 rotatably mounted on the fixed plate 2 and the adjusting plate 4 respectively on their adjacent sides, a roller body 6 provided between the two connecting cylinders 5, the two ends of the roller body 6 extending into the two connecting cylinders 5 respectively, and fixing bolts 7 threadedly mounted on the connecting cylinders 5 and connected to the roller body 6. By setting the fixing plate 2 fixed to the top of the base 1 and the adjusting frame 3 and adjusting plate 4 movably mounted on the base 1, the distance between the adjusting plate 4 and the fixing plate 2 can be flexibly adjusted to adapt to the installation requirements of roller bodies 6 of different lengths, enhancing the applicability of the device. By setting the connecting cylinders 5, the two ends of the roller body 6 can be stably embedded and can rotate with the connecting cylinders 5 to simulate the real working state. By using the fixing bolts 7 threadedly mounted on the connecting cylinders 5 and connected to the roller body 6, the roller body 6 can be firmly locked to prevent the roller body 6 from shifting or falling off during testing, ensuring the safety and reliability of the testing process.

[0025] The top of the base 1 is fixed with a guide frame 18 for limiting the movement path of the adjustment frame 3. The adjustment frame 3 is slidably mounted on the guide frame 18. A limiting bolt 22 connected to the guide frame 18 and used to stabilize the adjustment frame 3 is threaded onto the adjustment frame 3. By setting the guide frame 18 and allowing the adjustment frame 3 to slide on the guide frame 18, the movement path of the adjustment frame 3 is limited, ensuring that the adjustment frame 3 remains stable and does not deviate during movement, thus improving the accuracy and reliability of the adjustment process. By installing the limiting bolt 22 connected to the guide frame 18 on the adjustment frame 3, the adjustment frame 3 is stabilized, preventing the adjustment frame 3 from loosening or moving due to force during the test, thereby ensuring the stability of the roller test.

[0026] Both the fixed plate 2 and the adjusting plate 4 are equipped with electric telescopic rods 23. A limiting plate 24 for stabilizing the carrier's movement path is installed on the output rod of the electric telescopic rod 23. By installing the electric telescopic rods 23 on the fixed plate 2 and the adjusting plate 4, the position of the limiting plate 24 can be flexibly adjusted according to the specifications of the roller body 6, enhancing the versatility and adaptability of the device. The limiting plate 24 installed on the output rod of the electric telescopic rod 23 stabilizes the carrier's movement path, effectively preventing carrier displacement on the roller body 6 during testing. This prevents the roller body 6 from shifting or shaking due to uneven force or external interference, ensuring the stability of the test.

[0027] The guide frame 18 is provided with a sliding groove 19, and a slider 20 is slidably installed in the sliding groove 19. The slider 20 is connected to the adjusting frame 3. The bottom of the adjusting frame 3 is inlaid with a ball bearing 21 that contacts the top of the base 1 to reduce friction. By providing a sliding groove 19 on the guide frame 18 and slidably installing the slider 20 in the sliding groove 19, and connecting the slider 20 to the adjusting frame 3, the adjusting frame 3 can slide smoothly along the guide frame 18, ensuring the accuracy and stability of the movement of the adjusting frame 3. By inlaying the ball bearing 21 at the bottom of the adjusting frame 3 that contacts the top of the base 1, the friction is reduced, making the adjusting frame 3 move more smoothly and reducing the resistance caused by friction.

[0028] The spring 10 is provided with a limiting telescopic rod 16 for limiting the extension and retraction path of the spring 10. The limiting telescopic rod 16 is fixed between the adjusting block 9 and the U-shaped plate 11. The adjusting block 9 is equipped with a connecting plate 17 that is connected to the base 1 by adjusting bolts. By setting the limiting telescopic rod 16 in the spring 10 and fixing the limiting telescopic rod 16 between the adjusting block 9 and the U-shaped plate 11, the extension and retraction path of the spring 10 is limited, and the spring 10 can maintain linear motion when compressed or extended, avoiding bending or displacement of the spring 10. By installing the connecting plate 17 on the adjusting block 9, the position of the adjusting block 9 can be easily adjusted and the adjusting block 9 can be fixed.

[0029] A motor box 8 is fixed on the base 1. A servo motor for driving the connecting cylinder 5 to rotate is installed inside the motor box 8. The output shaft of the servo motor is connected to the connecting cylinder 5 located on the fixed plate 2 via a coupling. By fixing the motor box 8 on the base 1 and installing the servo motor for driving the connecting cylinder 5 to rotate inside the motor box 8, a stable rotational power is provided for the roller body 6. This allows the roller body 6 to simulate the rotation under actual working conditions during the test, ensuring that the test results are closer to the actual application scenario. By connecting the output shaft of the servo motor to the connecting cylinder 5 located on the fixed plate 2 via a coupling, the power is transmitted and the transmission error is reduced, ensuring the smooth rotation of the roller body 6.

[0030] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0031] The working principle of the roller loading test device provided by this utility model is as follows:

[0032] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0033] In use, first, according to the length of the roller body 6, slide the adjusting bracket 3 to move it on the guide frame 18, adjust the distance between the adjusting plate 4 and the fixed plate 2 so that both ends of the roller body 6 can be embedded into the connecting cylinders 5 on the fixed plate 2 and the adjusting plate 4 respectively. Then, use the fixing bolts 7 to firmly connect the roller body 6 and the connecting cylinders 5. Adjust the position of the adjusting block 9 on the base 1 through the connecting plate 17 and the adjusting bolts to adapt to rollers of different specifications. After adjustment, fix the adjusting block 9. According to the specifications of the roller body 6, start the electric telescopic rod 23 on the fixed plate 2 and the adjusting plate 4 (taking the Delco LT30 electric push rod as an example) to adjust the position of the limit plate 24. To stabilize the carrier's movement path and prevent the carrier (the structure that applies pressure to the roller) on the roller body 6 from shifting during the test, the servo motor in the motor box 8 (taking the Siemens 1FT7 servo motor as an example) is started. The servo motor drives the connecting cylinder 5 located on the fixed plate 2 to rotate through the coupling, thereby causing the roller body 6 to rotate, simulating the actual working state. When the roller body 6 is deformed by the loading force during rotation, the adjusting cylinder 12 will move accordingly, driving the U-shaped plate 11 and the connecting rod 13 to move. The reading head 14 cooperates with the grating 15 to detect the displacement distance of the adjusting cylinder 12, intuitively reflecting the degree of deformation of the surface of the roller body 6.

[0034] Compared with related technologies, the roller loading test device provided by this utility model has the following advantages:

[0035] This utility model provides a roller loading test device. By setting a fixed plate 2 fixed on the top of the base 1 and an adjusting frame 3 and adjusting plate 4 movably installed on the base 1, the distance between the adjusting plate 4 and the fixed plate 2 can be flexibly adjusted to adapt to the installation requirements of roller bodies 6 of different lengths, thus enhancing the applicability of the device. By using the spring 10 installed on the adjusting block 9 in conjunction with the U-shaped plate 11 and the adjusting cylinder 12, the degree of deformation of the roller can be detected. With the connecting rod 13 fixed on the U-shaped plate 11 and its reading head 14 and the grating 15 on the adjusting block 9, the degree of deformation of the roller surface can be intuitively reflected by detecting the displacement distance of the adjusting cylinder 12, thus making up for the deficiencies of visual observation.
