Embodiment Construction

[0018] Referring to Fig. 1 and Fig. 2, the present invention is a kind of high-speed trolley cable conveying system of container crane, and it mainly is made up of drag frame assembly 2, tackle assembly 3, tackle traction mechanism 4, guide rail system 5 and rubber belt 6 etc. The number 7 in Fig. 1 is the hinge point center of the front and rear girders; the number 8 in Fig. 2 is the front girder, 9 is the rear girder, 10 is a pulley, and 11 is a roller assembly.

[0019] Referring to Fig. 3 and Fig. 4, the drag frame assembly 2 includes a drag frame 21 fixed on the high-speed trolley 1 of the crane through a support 13 and a support 12 for fixing cables at the hinge point of the rear girder. The drag frame 21 is fixed on the support 13 by bolts, and then integrally welded on the high-speed trolley 1 of the crane. Rubber band 6 is placed on drag frame 21 by cable clamping plate 15 among Fig. 3. The rubber belt 6 is provided with an arc-shaped groove to separate the cables, a...

Abstract

A system using dan to transport cable at high speed for container crane consists of driving frame assembly, pulley assembly, pulley towing mechanism, guide rail system and rubber belt. The system can save 50% of cable and can increase service lifetime of the cable comparing with mode of hanging cable car on crane beam.

Description

technical field [0001] The invention relates to a container crane, in particular to a high-speed trolley cable conveying system for the container crane. Background technique [0002] With the increasing development of the container transportation industry, in order to cope with the increasing cargo volume and to obtain the maximum economic benefits, the ship owners specially build the container transportation ships bigger and bigger. In order to cope with the ever-increasing transport ships and to obtain the greatest economic benefits, the wharf hopes that the container cranes will be tall and large, and the unloading speed will be accelerated. [0003] At present, there is a quay bridge capable of loading and unloading the largest container ship in the world. The girder of this type of quay bridge reaches more than 60 meters. If the running speed of the high-speed trolley of the crane is not increased, the lengthening of the front reach of the girder is equivalent to prolo...
