Description

Technical Field

[0001] The present invention relates to the technical field of electric rollers, and specifically to a test vehicle frame for an electric roller. Background Art

[0002] An electric roller generally refers to a rotating roller driven by an electric motor, which is widely used in fields such as conveying systems, industrial equipment, and fitness equipment (such as treadmills). The test vehicle frame of an electric roller (also known as a test frame, trial frame, or commissioning frame) is a special device used for functional testing and performance verification of an electric roller before leaving the factory, after repair, or before installation. Its main function is to simulate the actual working environment to ensure that various parameters of the electric roller (such as rotational speed, torque, temperature rise, noise, sealing performance, etc.) meet the design requirements, avoid problems being discovered only after installation, and improve reliability and safety.

[0003] After retrieval, a Chinese patent with the application number "CN202223167294.6" is specifically a test vehicle frame for an electric roller. The counterweight includes a fixing plate fixedly connected to the surface of the transmission belt. A connecting rod is fixedly provided on the side of the fixing plate away from the transmission belt, and a number of counterweight rings are arranged on the surface of the connecting rod. More specifically, the weight of the counterweight rings can increase the resistance of the transmission belt and apply an external load to the transmission belt.

[0004] When testing an electric roller, the test vehicle frame is used to detect the performance of various parameters of the electric roller under the condition of having an external load installed. However, the counterweight is in a relatively static state during transportation and cannot simulate the test under the condition of vibration of the counterweight. Especially in ore mining, when the electric roller controls the transportation of ore, the vibration generated by the collision of ore with ore will affect the performance of the electric roller, resulting in low authenticity of the test of the test vehicle frame.
