Standards based MT/T318.1-1997 content of the coal industry, combined with precision test equipment, in line with simple, compact equipment, long service life, the design principles of continuous operation, the machine uses a combination of hydraulic and mechanical transmission steel skeleton structure, can be based on five different arbitrary replacement drum samples. Company SJDN-02 type automatic correction based on the increase and hydraulic locking device systems, machine operation and detect more perfect. , By the time the meter electric drive distribution components, actuators, computers, PLC, printers, etc., through the appropriate combination of the above devices, data acquisition, preservation. Test equipment to do the whole user-friendly design. The product is a dynamic endurance strength testing machine meets MT/T318.1-1997 "coal conveyor belt mechanical joint technical conditions" in the conventional dynamic endurance test strength test requirements.Structure?1, the mechanical part a, a fixed cylinder, hydraulic mobile drum set, b, mechanical transmission device, c, joists device, d, racks, e rotary arm hang (with user can reduce operator workload), e automatic correction device. 2, the hydraulic part a, hydraulic station, b, a hydraulic locking device, c, tensioning cylinder, d, solenoid valve. 3, electric control part a, the operation control computer system, b, displays the printing system, c, data acquisition system, d, electrical drive systems, e, a measuring instrument, the displacement sensors, f automatic correction device.
