Design And Research On Power Charging And Testing Device By Roller For Rigid Tank Track Of Mine Hoist

In recent years,with the gradual improvement of the safety requirements of the mine hoisting system,a series of monitoring and detection equipment are installed on the hoisting container to ensure its stable operation.At present,the mining lithium battery is installed on the hoisting container to supply power and must be replaced manually once it is exhausted,which wastes human and material resources and has potential safety hazards.In order to solve this problem,this paper studies and designs the power charging and testing device by roller for rigid tank track of the mine hoist.First of all,the composition and working principle of the mine hoist system are introduced,including the power consumption demand and environmental requirements of the mine hoist system.By comparing the two kinds of contact friction power generation methods of the roller with tank ear and with the rigid tank,the reliable power generation is proposed through using the contact friction of the roller with the rigid tank,the feasibility of the roller charging power generation and testing device of the tank track is verified at the same time.Secondly,the roller friction contact power generation device of the direct acting offset cam mechanism is designed for the first time.In order to make the roller always press the rigid tank,the whole device is arranged obliquely,and press it by gravity and spring force.The response is faster than simply using spring compression,which ensures that the roller always presses on the rigid tank even when the lifting container swings from one side to the other side with the largest swing.The spring can also play a buffering role to ensure the stable speed of the generator.On this basis,the components are designed,such as roller friction contact device and buffer and compression device,which are calculated,select and optimized.The spring force sensor is designed to monitor the roller exerting the rigid tank road compression force,and the intelligent diagnosis is given according to the compression force.The dynamic characteristics of the device are analyzed in the undamped and damped state.According to the characteristics of mining lithium battery,the matching charging and testing circuit is designed.Then,in order to verify the design scheme of,a three-dimensional model of the roller friction contact device,the belt drive device,the buffer and compression device and the overall device is established.In addition,the performance analysis of the key parts and the overall device is carried out,and verify its static and vibration properties.The position and groove thickness of the spring force sensor are optimized to improve the measurement accuracy.The dynamic model of the roller generator device and the simulation of the rigid tank track are established,and the dynamic performance of the roller generator device is tested based on ADAMS and MATLAB.The optimization is carried out according to the results,which show that the roller generator can generate electricity reliably.At last,the performance of the device is simulated and test.Firstly,the performance test is carried out to analyze the relationship between the deformation and the compression force of the roller,which verifies that the preload of the overall device can be full.At the same time,the model of charging and testing circuit is established and its performance is verified.Finally,the performance test of the charging and testing circuit is carried out,the mine lithium battery can be charged reliably through the test results.The overall test results show that the power charging and testing device by roller for rigid tank track of the mine hoist run smoothly and can achieve reliable charging and power generation.There are 78 figures,19 tables and 80 references in this paper.
