A mobile handling rack for a port logistics park

Abstract

The utility model discloses a kind of mobile handling goods shelves for port logistics park, including support frame, the support frame is rotatably connected with rotating shaft, the rotating shaft is fixedly connected with two support wheels, detachably connected with goods shelf on the support frame, the rotating shaft is fixedly connected with bevel gear one, the bottom of the support frame is fixedly connected with support plate, the support plate is rotatably connected with connecting shaft, the connecting shaft is fixedly connected with bevel gear two, the bevel gear one and bevel gear two engage, the upper end of the connecting shaft is fixedly connected with connecting block, the connecting block is provided with circumferential equidistance blind hole, centrifugal hook is slidably connected in the blind hole of the connecting block, the centrifugal hook and the connecting block between fixedly connected with elastic member. When goods shelf is unexpectedly out of control and accelerates to slide on ramp, centrifugal hook is thrown out under the action of centrifugal force and overcomes the tension of elastic member, engages with connecting rod, finally locks rotating shaft and support wheel through gear set, to realize automatic emergency brake.
