Abstract
The utility model discloses a crane dolly carrier roller, which comprises a crane dolly track, a dolly running gear, a dolly frame and an electric block. The crane dolly carrier roller is characterized in that brackets are installed at both ends of the dolly frame; carrier rollers are installed on the brackets; and strip adjusting holes are arranged at the installation places of the brackets and the dolly frame. The crane dolly carrier roller has the advantages that carrier rollers are additionally installed at two ends of the dolly frame and the carrier rollers contact with the lower plane of an I-shaped steel track, so side force caused by rocking of a grab bucket can be effectively counterbalanced, thus protecting the dolly running gear and improving service life of the equipment.
Description
Technical field
The utility model relates to the dolly carrying roller on a kind of hoisting crane, is specially adapted to use on the electric single-beam cucurbit bridge grabbing crane dolly.
Background technology
Electric single-beam cucurbit bridge grabbing crane is a kind of small-sized weight-hauling equipment, and the dolly of this type hoisting crane is a suspension type, during trolley travelling, grab bucket rock and rocking of dolly self very easily damaged wheeling mechanism, reduce the service life of equipment.
Summary of the invention
Task of the present utility model is to propose a kind of side force that generation is rocked in grab bucket of offsetting, the dolly holder rod on the hoisting crane of protection wheeling mechanism.Task of the present utility model is done in such a way that it comprises monkey track, wheeling mechanism, trolley frame and electric block is characterized in that: support is equipped with at the trolley frame two ends, and carrying roller is housed on the support, support and trolley frame installation place have adjustment hole, adjustment hole be shaped as bar shaped.The utlity model has following effect, install carrying roller additional at the trolley frame two ends, carrying roller contacts with the i-beam track lower plane, offsets the side force of being rocked generation by grab bucket effectively, has protected wheeling mechanism, has improved service life of equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the idler structure scheme drawing
The drawing explanation
Hoist electric block 6 of 1 monkey track, 2 wheeling mechanisms, 3 carrying rollers, 4 trolley frames 5 opens and closes electric blocks 7 grab buckets 8 adjustment holes 9 supports 10 mandrels 11 bearings 12 spacers 13 nuts
Specific embodiment
Describe embodiment in detail in conjunction with above accompanying drawing; carrying roller 3 is installed on the support 9 by mandrel 10; the bearing 11 that rotates for holder rod 3 is equipped with at the two ends of mandrel 10; bearing 11 is fixed on the support 9 by spacer 12 and nut 13; support 9 is installed in the two ends of trolley frame 4; adjust the distance of carrying roller 3 and monkey track 1 lower plane by adjustment hole 8; because the trolley frame two ends have increased carrying roller; when dolly rocks the generation side force; carrying roller contacts with the i-beam track lower plane; thereby offset the side force of rocking generation by grab bucket, protected wheeling mechanism.
