Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] The embodiment of container crane of the present invention is as follows:

[0017] Such as figure 1 , figure 2 The anti-rolling container crane shown includes a trolley 9 and a spreader 11 below the trolley. The crane 9 is provided with two sets of anti-sway mechanisms corresponding to two ends of the spreader 11 respectively. The anti-rolling mechanism includes a pair of fiber-drawing driving devices parallel to the running direction of the trolley. The rotating shafts of the two devices are perpendicular to the traveling direction of the trolley. The first fiber-drawing driving device includes: the first reel driving motor 1, which drives the first reel through the gear chain structure. Drum 3, the pulley 5 on the outside of the first reel 3, the first anti-sway stay rope 7 is wound on the first reel 3, the first anti-sway stay rope 7 passes throu...

Abstract

The invention relates to a roll reduction container crane and a roll reduction mechanism thereof. The crane is provided with at least two roll reduction mechanisms, wherein each roll reduction mechanism comprises a pair of same towing driving devices, each towing driving device comprises a drum driving motor, a friction brake synchronizing device is arranged between output shafts of two drum driving motors, the friction brake synchronizing device is composed of two friction plates which are sticked together and rotate synchronously, and the two friction plates are respectively connected with the corresponding drum driving motor in a transmission way. When a lifting appliance swings, a roll reduction hauling cable at one side is retracted, and the roll reduction hauling cable at the other side is released. By utilizing the friction brake synchronizing device, the volicity difference of the retraction and release of the two sides of roll reduction hauling cables is braked directly, therefore, the swing of the lifting appliance is braked, and excellent lifting applicance roll reduction effect is reached.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a container crane with an anti-sway function and an anti-sway mechanism thereof. Background technique [0002] Various cranes used in container ports, including container quay cranes, rail-mounted and tire-type container gantry cranes, etc., have high working level and fast running speed, and have high requirements for anti-rolling of spreaders. At present, the anti-rolling system of container cranes, whether it is a mechanical anti-rolling system or an electronically controlled anti-rolling system, is not very effective in practical application. [0003] The Chinese patent document whose application number is 200920232267.8 discloses a anti-sway mechanism of a container lifting spreader. The drive device includes two front and rear drive devices, and each drive device drives its own reel to wind in and release its own anti-sway stay cord, and the two anti-sway stay cords are arranged cros...
