The present invention relates to the technical field of section steel straightening, and more particularly, to a straightening roll integral replacement device for a section steel straightener. The straightening roll integral replacement device comprises a hydraulic roll change buggy as well as an upper hydraulic roll stand and a lower hydraulic roll stand which are used in conjunction with the hydraulic roll change buggy. The hydraulic roll change buggy comprises base guiding rails, a placing platform for the roll stand, guiding posts for the roll stand, synchronous jacking hydraulic cylinders, a transverse hydraulic cylinder and a three-position four-way solenoid valve; the upper hydraulic roll stand includes an upper roll stand body which is provided with first arc-shaped supports, first ear-shaped hooks, holes for shafts of lower straightening rolls to go through and first guide sleeves; the lower hydraulic roll stand includes a lower roll stand body which is provided with second arc-shaped supports, second ear-shaped hooks and second guide sleeves. The straightening roll integral replacement device realizes the function of integrally replacing the working upper straightening rolls and upper straightening rolls, reducing the time of such replacement and the production intensity of laborers.
Description
(1) Technical field [0001] The invention relates to the technical field of section steel straightening, in particular to a whole replacement device for straightening rollers for a section steel straightening machine. (2) Background technology [0002] At present, domestic straightening machines are generally 10-roller or 8-roller cantilever-type straightening machines. When replacing the straightening rollers, all the cranes are manually operated. First, loosen the locking device on the shaft end of each straightening roller, and then use Wire ropes or slings are disassembled one by one, and the order is reversed when installing straightening rollers. This kind of manual operation takes a long time to replace, generally takes 1.5-2.5 hours, which not only seriously affects the operating efficiency of the workshop, but also has the hidden danger of the straightening roller slipping and hurting people. (3) Contents of the invention [0003] In order to make up for the defic...
