The existing connection between the suspension arm and the upright column has insufficient strength and can not load heavy goods, or the manufacturing cost is increased due to overhigh manufacturing cost.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an kind of cantilever crane device, its davit is firm with being connected of stand, rotates in a flexible way.

In order to solve the technical problem, the technical scheme of the utility model is that the cantilever crane devices comprise a stand column fixed on a pier seat, a suspension arm vertically arranged on the stand column and capable of rotating around the stand column, an electric hoist capable of running back and forth along the suspension arm is arranged on the suspension arm, a rotating shaft vertically fixed on the stand column is further included, the suspension arm is fixed on the rotating shaft, an upper bearing seat and a lower bearing seat are fixed with the stand column through a connecting plate, bearings are arranged in the bearing seats, inner rings of the bearings are fixedly sleeved on a connecting shaft, the rotating shaft is hollow, end covers are arranged at two ends of the rotating shaft, connecting holes for the connecting shaft to penetrate through are formed in the end covers, and sealing plates larger than the connecting holes are fixed at the tail ends of the connecting.

As improvements, the head of the connecting shaft is sleeved with a gear, and the suspension arm further comprises a driving gear meshed with the gear, wherein the driving gear is driven by a motor.

As improvements, the head parts of the upper connecting shaft and the lower connecting shaft are respectively provided with a gear, the two driving gears are an upper driving gear and a lower driving gear which are respectively meshed with the two gears, the two driving gears are linked by a connecting rod, and force is applied to the upper part and the lower part simultaneously, so that the stress of the rotating shaft is more balanced.

preferably, a reinforcing plate is provided between the arm and the rotating shaft to improve strength.

As improvements, the bearing sleeved on the upper connecting shaft is a one-way thrust ball bearing, and the bearing sleeved on the lower connecting shaft is a self-aligning roller bearing.

it is preferable that the bearing seat is provided with dust covers above and below the bearing to prevent dust from entering and fouling the bearing.

As an improvement of , the tail end of the connecting shaft is conical, and the connecting hole in the end cover is in a conical sleeve shape matched with the connecting hole, so that radial play caused by displacement of the connecting shaft and the end cover is avoided.

The utility model has the advantages that rotating shafts are independently arranged for installing the suspension arm, the suspension arm lifting device with the structure is convenient to maintain and replace even if damaged, and the rotating shafts can bear larger load and can flexibly rotate under the condition of load.
