Description

Technical Field

[0001] The utility model belongs to the technical field of sound insulation devices, and specifically relates to a sound insulation room for a speed sensor test bench. Background Technique

[0002] Speed sensors are widely used in modern industry, especially in rail transit, automation equipment, and mechanical control systems. Their accuracy and reliability play a crucial role in the operation of the entire system. However, during the testing process of speed sensors, the generation of noise often has an adverse impact on the accuracy of test results and the comfort of the test environment.

[0003] In related technologies, speed sensor test benches usually use heavy protective covers to isolate noise. However, such designs not only occupy a large amount of space and are inconvenient to operate, but also cannot effectively reduce noise to an ideal level. Moreover, the opening and closing of the protective cover require manual operation. Especially when installing and disassembling sensors, this design increases the operation difficulty and is not conducive to improving the test efficiency. In addition, the protective cover also has obvious deficiencies in sound insulation effect and cannot effectively isolate the noise generated during high-speed rotation, thus affecting the working environment of operators and even potentially causing adverse effects on their health. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a sound insulation room for a speed sensor test bench, which can reduce noise.

[0006] A sound insulation room for a speed sensor test bench according to an embodiment of the utility model has at least the following beneficial effects:

[0007] By designing the sliding structure of the upper and lower opening doors and combining the use of the electric chain door assembly, the electric opening and closing operation of the soundproof door is realized. This design not only simplifies the process of sensor installation and disassembly but also reduces the inconvenience brought by traditional manual operations, especially in a frequent testing environment, significantly improving work efficiency. The side of the soundproof room frame adopts a multi-layer soundproof wall design, which can more effectively reduce the noise generated during the operation of high-speed rotating equipment compared with traditional protective covers. This design reduces the noise level to below 80 decibels, thus providing a more comfortable and safe working environment for testers and reducing the impact of noise on test results and personnel health. The frame is designed to be strong and durable, and high-quality materials are used, such as triple-layer double PVB laminated glass as the glass panel on the top of the soundproof room, further enhancing the soundproof effect and the structural stability.

Since both ends of the chain are respectively connected to the upper opening door leaf and the lower opening door leaf, it can effectively disperse the load and reduce mechanical wear, thereby extending the service life of the soundproof door.

[0013] According to some embodiments of the present utility model, a driving motor is installed on the top of the front door frame assembly through a motor mounting seat. The driving motor is drivingly connected to a transmission rod.

[0014] According to some embodiments of the present utility model, the sprocket is installed on the transmission rod, and the lifting operation of the upper and lower door leaves is realized through the sprocket. This design ensures that the opening and closing operation of the door is smoother and more accurate, reduces the error in mechanical operation, and improves the reliability of the entire system.

[0015] According to some embodiments of the present utility model, the transmission rod includes a left transmission rod and a right transmission rod, and the left transmission rod and the right transmission rod are fixedly connected through a connecting sleeve. This modular transmission structure is not only convenient for assembly and maintenance, but also enables the length and position of the transmission rod to be adjusted according to actual needs, providing greater flexibility.

By designing the sliding structure of the upper and lower opening door leaves 5 and combining the use of the electric chain door assembly 7, the electric opening and closing operation of the soundproof room door is realized. Such a design not only simplifies the process of installing and disassembling the sensor, but also reduces the inconvenience brought by traditional manual operations, especially in a frequent test environment, significantly improving the work efficiency. The side of the frame of the soundproof room adopts a design of multiple layers of soundproof walls 3, which can more effectively reduce the noise generated during the operation of high-speed rotating equipment compared with traditional protective covers. This design reduces the noise level to below 80 decibels, thus providing a more comfortable and safe working environment for testers and reducing the impact of noise on test results and personnel health. The frame is designed to be strong and durable, and at the same time, high-quality materials are used, such as triple-layer double PVB laminated glass as the glass plate 4 on the top of the soundproof room, further enhancing the soundproof effect and the stability of the structure.
