Description
Technical field
The utility model relates to crane field, is specifically related to a kind of single girder dolly transfer crane.
Background technology
The one distortion of crane in bridge type during transfer crane.The loading and unloading operation of material is mainly used in road and bridge build.Its metal construction, as door-shaped frame, is installed two supporting legs under support main beam, can directly be walked on the track of bottom surface.Current most domestic adopts two girder portal crane, and existing pair of girder portal crane complex structure installs inconvenience, and rolled steel dosage is large, and cost is higher, waste raw MAT'L.And running into the bending situation of track laying, easily there is the situation of wheel gnawing rail in traveling mechanism of the larger traveller.
Summary of the invention
In order to better solve problem existing in above-mentioned prior art, this use is novel provides a kind of single girder dolly transfer crane.
In order to realize foregoing invention object, the technical solution of the utility model is: a kind of single girder dolly transfer crane, comprise girder, dolly, left, right supporting leg, lift system and electric system, wherein, described girder two ends and a described left side, the upper end of right supporting leg connects, a described left side, lower road wheel case is equipped with bottom right supporting leg, described girder top is provided with walking dolly, bottom is provided with lift system, the longitudinal cross-section of described girder is inverted triangle structure, described girder comprises two horizontally disposed entablatrances and a cross sill, described cross sill is positioned at position, middle below described two entablatrances, multiple connection reinforcement part is provided with between described entablatrance and between entablatrance and cross sill, described lower road wheel case is flexibly connected with described supporting leg.
Described lower road wheel case is flexibly connected with described supporting leg by rotating shaft mechanism.
Described rotating shaft mechanism is fixed on lower walking opinion box top, comprise bearing pin and with bearing pin with the use of nut, described box top of taking turns is provided with a bearing groove, placement force bearing in bearing groove, described pressure bearing and described pinned connection, described bearing pin and described supporting leg are fixed together.
Beneficial effect:
1, the utility model list girder dolly transfer crane is cost-saving, and convenient transport, in-site installation is convenient.The utility model list girder dolly transfer crane is single girder, and main beam structure is inverted triangle version, and structure is simple, and has saved cost when ensureing safety, makes in use to facilitate transport, and in-site installation is convenient; Under 2 the utility model list girder dolly transfer cranes, road wheel case runs and can rotate, and solves the phenomenon that track bends wheel gnawing rail in situation.The utility model list girder dolly transfer crane bottom roller box adopts rotating shaft mechanism to connect, and solves the phenomenon that track bends wheel gnawing rail in situation.
