Description

Technical Field

[0001] This utility model relates to the field of testing and measurement technology, and in particular to a roller noise and rotational resistance detection platform. Background Technology

[0002] Idler rollers are an important component of belt conveyors, and their performance directly affects the stability, energy consumption, and service life of the conveyor. Among the many performance indicators of idler rollers, noise and rotational resistance generated during operation are two key parameters for measuring their manufacturing quality and operational status. Therefore, accurate noise and rotational resistance testing of idler rollers before they leave the factory is a necessary step to ensure product quality and efficient operation of the conveying system.

[0003] In existing testing practices, these two performance characteristics of idlers are usually measured separately. However, the operating conditions and sources of interference for these two tests are fundamentally different. For noise testing, the core is to accurately capture the faint sounds emitted by the idler's own bearings and other components during operation. This requires that the testing environment, especially the noise and vibration of the drive source itself, must be shielded to the greatest extent possible. Otherwise, the background noise generated by the drive system will easily drown out the true noise signal of the idler under test, leading to serious distortion of the measurement results.

[0004] On the other hand, the core of rotational resistance testing lies in realistically simulating the stress state of the idler roller under actual working conditions. This involves applying a constant radial load to the roller body while simultaneously driving the roller shaft to rotate, and accurately measuring the resulting resistance torque. This requires a stable and precise loading method, and the driving method must not interfere with the resistance measurement. Existing testing devices often struggle to simultaneously meet these two drastically different testing conditions.

[0005] To simultaneously perform both types of detection, existing technologies often employ a single drive and loading system, which inevitably leads to structural compromises. For example, complex transmission systems designed to isolate noise may introduce unstable frictional forces, interfering with the accurate measurement of rotational resistance; while direct drive systems designed for accurate resistance measurement suffer from difficulty in effectively isolating the noise and vibration of their own motors, thus compromising the accuracy of noise detection. This inherent technical contradiction makes achieving high-precision, high-efficiency detection of idler roller noise and rotational resistance on a single platform a pressing technical challenge.

[0006] Therefore, this utility model proposes a roller noise and rotational resistance detection platform to address the shortcomings of the prior art. Utility Model Content

[0007] To address the problems of existing idler noise and rotational resistance detection platforms, such as the inability to effectively shield background noise from the drive motor during noise measurement leading to inaccurate measurements, the difficulty in accurately simulating actual working conditions with varying loading and driving methods during rotational resistance measurement, and the structural technical contradictions that result in low detection efficiency when integrating the two detection functions into a single platform, this utility model aims to provide an improved idler noise and rotational resistance detection platform that can effectively solve the above problems.

[0017] Preferably, as a further limitation of the loading component, the cylindrical locking rod of the height adjustment rod assembly is provided with a height locking button for locking the load counterweight.

[0018] Preferably, the rotational resistance detection mechanism further includes a corrugated sensor and a sensor sag support, wherein the corrugated sensor is mounted on the slider of the sensor sag support and connected to the height adjustment rod assembly.

[0020] Preferably, the platform further includes an electrical control system, which is electrically connected to the noise sensor, the S-shaped tension / compression load cell, the ripple sensor, the first silent geared motor, and the second silent geared motor.

[0022] 2.

It achieves the technical effect of high functional integration, high detection efficiency, and cost and space saving.

[0023] 3. This utility model solves the problem of difficulty in accurately applying and quantifying radial load during noise detection by designing the soundproof power box of the noise detection mechanism as a suspension structure and using a load adjustment mechanism to adjust its suspension position via an S-shaped tension and compression weighing sensor to change the tension of the O-belt. This achieves the technical effect of cleverly combining drive transmission with load application and making the load application precise and controllable.

[0033] Please refer to the following carefully. Figure 1 and Figure 2 The structure of the noise detection mechanism 5 will be described in detail below: The noise detection mechanism 5 includes a fixed hanging shaft seat 501, which is installed below the worktable of the detection platform body 1. A power box hanging shaft 502 is fixed on the fixed hanging shaft seat 501.

[0042] As another preferred embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The structure of the rotational resistance detection mechanism 10 is defined. The rotational resistance detection mechanism 10 also includes a loading assembly, which includes a height adjustment rod assembly 103 and a load counterweight 105. The height adjustment rod assembly 103 includes a friction belt that passes around the cylinder of the detection roller 13 and suspends the load counterweight 105. The cylindrical locking rod of the height adjustment rod assembly 103 is provided with a height locking button 104 for locking the load counterweight 105.

[0043] As a further definition of the rotational resistance detection mechanism 10, the rotational resistance detection mechanism 10 also includes a corrugated sensor 101 and a sensor sag support 102. The corrugated sensor 101 is mounted on the slider of the sensor sag support 102 and connected to the height adjustment rod assembly 103.

[0045] The working principle of this utility model's idler roller noise and rotational resistance detection platform is as follows: When testing is required, the shaft end of the testing roller 13 is first adjustablely installed between the main shaft flange three-grip chuck assembly 7 and the outer rotating body rotary tip 8 on the testing platform body 1. The main shaft flange three-grip chuck assembly 7 and the outer rotating body rotary tip 8 are slidably connected to the first aluminum profile guide rail 3 and the second aluminum profile guide rail 4, respectively. The first aluminum profile guide rail 3 and the second aluminum profile guide rail 4 are fixed to the plug-in guide rail assembly 2.

[0046] During noise testing, an O-belt 6 is fitted onto the belt drive pulley 507 of the first silent reduction motor 506, the cylinder of the detection roller 13, and the belt drive pulley 507 of the second silent reduction motor 9. Then, the handwheel of the load adjustment mechanism 512, mounted on the load adjustment mechanism hanger 508, is rotated. The load adjustment mechanism 512 is lifted and suspended from the soundproof power box 505, which is connected to the power box hanger shaft 502, via the S-type tension / compression load cell 509 and the hinge bolt 11. The power box hanger shaft 502 is fixed to the fixed hanger seat 501. This lifting action tensions the O-belt 6, thereby applying a radial load to the cylinder of the detection roller 13.

[0047] When performing rotational resistance testing, firstly, adjust the load adjustment mechanism 512 to loosen and remove the O-belt 6; then, the friction belt of the height adjustment rod assembly 103 in the rotational resistance testing mechanism 10 is wrapped around the top of the cylinder of the testing roller 13, and the load counterweight 105 is suspended and fixed on the height adjustment rod assembly 103 through the height setting button 104 to apply a radial load to the testing roller 13; start the second silent reduction motor 9, which is connected to the main shaft flange three-grip chuck set 7 to drive the shaft of the testing roller 13 to rotate; at this time, the corrugated sensor 101 installed on the slider of the sensor sag support 102 detects the tangential force generated by friction and transmits the static force and dynamic force signals to the electrical control system 12 for processing.
