Description
Technical field
The present invention relates to a kind of bank bridge, especially a kind of bank bridge with lifting mode truss crossbeam and three dollies, belongs to harbour container logistics field.
Background technology
In the logistics field of harbour container, bank bridge system plays irreplaceable effect in container handling system, but along with the process of international trade is constantly accelerated, the freight transport volume at harbour is also in cumulative year after year, the work efficiency of quayside container crane system has obtained unprecedented test, and the work efficiency that therefore how to improve container handling bank bridge becomes problem instantly anxious to be resolved.
At present, general harbour container bank bridge be by single lifting trolley by freight container from ship hang oneself transport to the top of truck or from truck handling to ship, in handling process, because lifting trolley lower end suspender is far apart from lifting trolley, now suspender is as easy as rolling off a log swings, cause suspender and freight container to bit comparison difficulty, have a strong impact on the efficiency of container handling system handling, in order to contribute to freight container and suspender to carry out contraposition, need to increase anti roll device, prevent shaking effect although can play, can increase like this complexity of equipment; In addition, in handling ship process, because freight container needs stacking highlyer, therefore in the time of design, the lifting mechanism of lifting trolley need to be chosen higher working level, so the integral structure of container handling bank bridge is relatively large, cause its production, use and maintenance cost higher.
Summary of the invention
The invention provides a kind of bank bridge with lifting mode truss crossbeam and three dollies, he can realize the function of bank bridge grider lifting, reduce the requirement of the lifting altitude of bank bridge system to lifting trolley, reduce the complexity of quayside container crane system, and can improve the handling efficiency of quayside container crane system.
Technical scheme of the present invention: a kind of bank bridge with lifting mode truss crossbeam and three dollies, comprise bank portal frame and bank bridge grider, bank bridge grider is located at the upper end of bank portal frame inner side, bank portal frame comprises four door frame columns, door frame column below is connected by connecting cross beam a, bank bridge grider is connected with the top of bank portal frame, and the upper strata of bank bridge grider is provided with two bank bridge lifting trolleys, and the lower floor of bank bridge grider is provided with suspension type transport carriage.In the aforesaid bank bridge with lifting mode truss crossbeam and three dollies, bank bridge grider is located at the inner side of bank portal frame and is connected by crossbeam latching device, the inner side on bank bridge grider top and the outside of bottom are equipped with trolley track, two ends in the inner track on bank bridge grider top are respectively equipped with a bank bridge lifting trolley, and the track in the outside of bank bridge grider bottom is provided with suspension type transport carriage; The top of four door frame columns is parallel is provided with two connecting cross beam b, the below of connecting cross beam b is provided with assembly pulley a, connecting cross beam a is provided with crossbeam lifting mechanism, and bank bridge grider top is provided with assembly pulley b, and the steel rope on crossbeam lifting mechanism is connected with bank bridge grider with assembly pulley b by assembly pulley a.In the handling ship process of carrying out freight container, the container transshipment pattern of two bank bridge lifting trolleys and a suspension type transport carriage coordinative operation has replaced traditional quayside container crane to use the pattern that hoist and transport of single lifting trolley to freight container, solve traditional single lifting trolley and hung the slow-footed persistent ailment of handling, improved dramatically the transport speed of freight container.
In the aforesaid bank bridge with lifting mode truss crossbeam and three dollies, the distance of the upper and lower two-layer track of bank bridge grider is 6m～10m.
In the aforesaid bank bridge with lifting mode truss crossbeam and three dollies, the distance of the upper and lower two-layer track of bank bridge grider is preferably 7m.
