The invention relates to
railway engineering machinery, particularly relates to a device for quickly loosening and tightening railway steel rail
fastener bolts and an operation method of the device, and the device is applied to the field of
railway engineering and equipment maintenance. The device comprises a base support 4, and is characterized in that the base support 4 is connected with a driven walking mechanism 1 and a driving walking mechanism 10; a
walking distance detection device 2 is connected with the driven walking mechanism 1, and a three-in-one speed
reducer 9 is connected with the driving walking mechanism 10 through a locking disc; a bolt position detection device 3 is connected with the base support 4 and is used for detecting the relative position of each group of
fastener bolts; a cross sliding guide rail and
servo driving device 7 is arranged on the upper surface of the base support 4, an electric
wrench 6 is arranged on the cross sliding guide rail and
servo driving device 7, a
diesel generator 5 is arranged on one side of the base support 4 to serve as a power mechanism of the whole device, and a control box and a control panel 8 are arranged on the other sideof the base support 4, and are used for controlling the whole device to automatically loosen and tighten railway steel rail
fastener bolts. According to the device for loosening and tightening the railway steel rail fastener bolts, manual assistance is not needed, tightening and loosening operation of the railway steel rail fastener bolts can be conducted in a full-automatic mode, an existing working mode that manpower is matched with a mechanical
wrench can be replaced, a large amount of manpower is saved, the working efficiency is greatly improved, and integrated construction is conducted in cooperation with a rail changing vehicle.
