无极绳连续牵引车新型防脱压绳轮装置设计OA

A mechanical analysis of the traditional anti-rope-off rope pressing wheel device is conducted,and it is determined that the traditional structure needs to increase the elastic force of the connecting tension spring when pulling a large load.Moreover,when the traction vehicle passes through the anti-rope-off device,the traditional structure is prone to huge impacts.At the same time,when a large traction force continues to act on the tension spring,it also accelerates the damage of the tension spring.In response to these problems,a new type of anti-rope-off rope pressing wheel device is designed,which includes a rotating arm that can drive two rope pressing wheels to rotate synchronously.The rotating arm can close and open between the two rope pressing wheels in one direction and only needs a small spring to reset the rope pressing wheel,thereby reducing the force on the spring.Moreover,when the shuttle passes through the two rope pressing wheels,the opening amplitude of the two rope pressing wheels is small,which effectively prevents the steel wire rope from slipping off during operation.Finally,after conducting field tests on the two structures,it is determined that the maximum tensile force and stationaritythat can be withstood by the new anti-rope-off rope pressing wheel device is significantly greater than that of the traditional structure.
