The upper surface of described carriage is arcs of recesses and is complementary with the barrel outer surface of trommel mixer.
The assembly and disassembly methods of the attaching/detaching apparatus of described trommel mixer carrying roller is characterized in that the method for dismounting of carrying roller is:
1) start hydraulic jack,
2) carriage cylindrical shell in the effect subiculum of hydraulic jack and is moved up, and climb is 110-130mm,
3) stop the rising of hydraulic jack,
4) connecting bolt on dismounting carrying roller and carrying roller basis,
5) with crane carrying roller is extracted out,
6) hydraulic jack is fallen after rise,
7) the carriage holder cylindrical shell fall back to original position under the effect of gravity, realizes the dismounting to carrying roller,
The installation method of carrying roller is:
1) start hydraulic jack,
2) carriage cylindrical shell in the effect subiculum of hydraulic jack and is moved up, and climb is 110-130mm,
3) stop the rising of hydraulic jack
4) with crane carrying roller is placed on the carrying roller basis,
5) with connecting bolt carrying roller and carrying roller basis is connected and fixes,
6) hydraulic jack is fallen after rise,
7) the carriage holder cylindrical shell fall back to original position under the effect of gravity, realizes the installation to carrying roller,
Described attaching/detaching apparatus is one group, can enable simultaneously, also can enable separately.
The attaching/detaching apparatus of trommel mixer carrying roller of the present invention and the advantage of assembly and disassembly methods are:
1, because the surface of base of trommel mixer is domatic, thus the support of jack all will be set during each dismounting carrying roller, can steady operation to guarantee jack.Adopt attaching/detaching apparatus of the present invention to exempt and jack stand is set and, makes the method for dismounting carrying roller simpler, time saving and energy saving, boost productivity with back loaded down with trivial details work of removing jack stand;
2, attaching/detaching apparatus of the present invention is located at appropriate location below the cylindrical shell of trommel mixer, thrust by hydraulic jack is with the steady jack-up of cylindrical shell, owing to the spacing and guide effect of guide post, limited the cross force of carriage, the stability when guaranteeing the carriage top lifting.Realize separating of cylindrical shell and carrying roller, can carry out the dismounting of carrying roller, its stability, security are higher;
3, attaching/detaching apparatus of the present invention is one group, and the position of setting is reasonable, and Stability Analysis of Structures can realize 4 carrying rollers of dismounting trommel mixer simultaneously, the also arbitrary carrying roller of dismounting separately, and do not influence miscellaneous part and overhaul dismounting;
4, need not dismounting after attaching/detaching apparatus of the present invention uses, economical and practical, long service life is put things right once and for all.
