Structural Design of a Hydraulic Control Clutch Tensioning Chain Device for Scraper Conveyor
At present,the hydraulic tensioning chain device of the scraper conveyor requires manual operation of its clutch handle before and after tensioning,in order to control the combination and separation between the idler wheel of the hydraulic tensioning chain device and the tensioning gear of the input shaft of the scraper conveyor reducer.In order to liberate labor and improve work efficiency,a hydraulic control clutch tensioning chain device structure was designed:a combination of reducer,hydraulic clutch,and low-speed high torque hydraulic motor.The characteristic of this structure is that when a tensioning chain is required,the connection work of the oil system of the tensioning chain device can be directly remote controlled.The reducer of this structure is connected in a spline manner in the inner cavity of the sprocket assembly of the scraper conveyor.With the oil supply for connecting and closing the hydraulic clutch,it controls the suction and separation of the intermediate connecting piece of the hydraulic clutch,achieving torque and speed transmission and disconnection between the reducer and the hydraulic motor.Through detailed scheme analysis and working principle inference of the structure,the results showed that the structure could achieve automated tensioning chain function.
