Described change is provided with locating guide device across overhead traveling crane, locating guide device comprises guide piece and registration device, guide piece is fixed on and becomes across overhead traveling crane rear and front end, and registration device is fixed on girder and becomes across completing normal place, becomes and completes change across rear accurately in place across overhead traveling crane by locating guide device.Locating guide device comprises orienting lug and locating piece, and orienting lug ensures to become to move to accurate location across overhead traveling crane, and locating piece is used for fixing change across overhead traveling crane.
The present invention becomes at lifting beam machine and increases traveling roller structure across overhead traveling crane corner, with original change across the pumping plant of oil cylinder into propulsion source, traveling roller designs vertical top oil-lifting jar, makes change upwards depart from girder across overhead traveling crane by cylinder jacking.
To utilize steel wire rope of windlass to draw to become across overhead traveling crane along rail moving, guide piece be set when moving to destination locations, guarantee to become across overhead traveling crane in place accurately after, retraction vertical top oil-lifting jar, makes overhead traveling crane to falling back on girder, and namely fixing overhead traveling crane completes change across operation.
The jacking cylinder of traveling roller structure adopts hydraulic efficiency pressure system to drive, and controls the action of oil cylinder practical function by control cock block.
Utilize additional steel rope and become and across the snap ring on overhead traveling crane, traction hanger and hoisting rope are coupled together, realize the change of 32m → 24m and 24m → 32m across operation by conversion connection mode.
Appropriate application field condition of the present invention makes change across more convenient, utilizes the vertical top oil-lifting jar of original HYDRAULIC CONTROL SYSTEM corner, by flexible the realizations top that controls oil cylinder from the action of falling girder, coordinate hoisting rope traction to realize change across operation.When ensureing safety, well improving and become across operating efficiency and reduce labour intensity.
